Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1, capsule liquid puncture decompression sleeve pipe under the bionical peritoneoscope of described a kind of Hirudo, comprises hollow and attracts sleeve pipe 1 and the movable puncture inner core 2 being nested with the hard in described attraction sleeve pipe 1.Described attraction sleeve pipe 1 head end arranges the bionical sucker 3 of annular Hirudo along attracting sleeve pipe 1 tube wall, and described attraction sleeve pipe 1 through tube wall major axis buries some negative pressure conducting tubes 4 for providing negative pressure for the bionical sucker 3 of Hirudo be communicated with the bionical sucker of Hirudo 3 underground.Described negative pressure conducting tube 4 completely cuts off with attracting the tube chamber of sleeve pipe 1, and described negative pressure conducting tube 4 goes out to attract the negative pressure booster source 5 of sleeve pipe 1 afterbody tube wall setting for providing negative pressure for the bionical sucker 3 of Hirudo.Described attraction sleeve pipe 1 afterbody is arranged and the attraction interface 6 for providing negative pressure for attraction sleeve pipe 1 attracting sleeve pipe 1 hollow tube chamber to be communicated with.Described puncture inner core 2 length comparatively hollow attracts sleeve pipe 1 long, and described puncture inner core 2 external diameter attracts the internal diameter of sleeve pipe 1 little compared with hollow, and described puncture inner core 2 can be nested with intracavity in attraction sleeve pipe 1 and move.
Described negative pressure booster source 5 attracts the negative pressure conducting tube 4 in sleeve pipe 1 tube wall to attract the bionical sucker of Hirudo 3 of sleeve pipe 1 head end to provide suitable negative pressure for being arranged on by being arranged on, and the bionical sucker 3 of the Hirudo of vacuum suction sleeve pipe 1 head end can be attracted on the cyst wall of cyst.Then, puncture inner core 2 pairs of cyst cyst walls are used to puncture to the cyst wall in the bionical sucker 3 of Hirudo through described attraction sleeve pipe 1 hollow tube chamber, puncture inner core 2 is extracted after having punctured, the attraction interface 6 of sleeve pipe 1 tail end is being attracted to connect Medical negative pressure connection tube, namely by attracting sleeve pipe 1 hollow tube chamber to carry out decompression drainage to the liquid in cyst.
Described Hirudo bionical sucker 3 inner ring edge part arranges the inner ring diaphragm seal circle of soft quality class annular.Inner ring diaphragm seal circle is set and can increases sealing when the bionical sucker 3 of Hirudo is adsorbed on cyst outer wall.Specific works principle is: before puncture and when puncturing, the bionical sucker of Hirudo 3 is negative pressure in annular adsorption zone, attract the attraction sleeve pipe 1 tube chamber district in Hirudo bionical sucker 3 inner edge of sleeve pipe 1 head end to be atmospheric pressure, gas or liquid flow tendency are for being flowed to the annular suction inlet side of the bionical sucker of Hirudo 3 by attraction sleeve pipe 1 tube chamber side.Under the pressure differential effect of tube chamber district atmospheric pressure and annular adsorption zone negative pressure, the potential gap that may occur between inner ring diaphragm seal circle distortion shutoff Hirudo bionical sucker 3 inner ring at Hirudo bionical sucker 3 inner ring edge and cyst cyst wall, is just uprooted before gas leakage or leakage still do not occur.It is noted that punctured rear in cyst liquid negative pressure attract time, in order to keep sealing between Hirudo bionical sucker 3 inner ring and cyst cyst wall, the absorption negative pressure of the bionical sucker 3 of Hirudo should be less than the negative pressure of liquid negative pressure attraction in cyst, ensure that the pressure differential of both sides does not take a turn for the worse.
Described Hirudo bionical sucker 3 outer ring edge part arranges the outer ring diaphragm seal circle of soft quality class annular, and be the sealing in order to increase when the bionical sucker 3 of Hirudo is adsorbed on cyst outer wall equally, principle is identical, repeats no more.
Described negative pressure conducting tube 4 connection arranges switch 41, for Rapid degassing after cyst excision, the bionical sucker 3 of described Hirudo is departed from cyst.During normal use, switch 41 cuts out, and ensures the seal of negative pressure conducting tube 4.When operation completes, when needing described attraction sleeve pipe 1 to depart from from cyst cyst wall, open switch 41, ambient atmos enters the bionical sucker 3 of Hirudo through switch 41, pressure and the ambient atmosphere of the bionical sucker 3 of Hirudo balance, pressure difference ends between the bionical sucker 3 of Hirudo and atmospheric pressure, adsorption disappears, and attraction sleeve pipe 1 can be departed from from cyst cyst wall.
Mouth-shaped and size and injector for medical purpose liquid outlet coupling in described attraction interface 6, its clinical meaning is: when needing to do pathological analysis or antibacterial culturing to the sampling of cyst capsule liquid, syringe liquid outlet can be connected through attracting interface 6 internal orifice, through the indwelling of syringe pump capsule liquid, complete pathological analysis or antibacterial culturing etc. further.
As shown in Fig. 4 and Fig. 6, when specifically implementing, described puncture inner core 2 head end arranges cutting edge 20, the preferred trident of cutting edge 20 shape, and trident cutting edge 20 converges at puncture inner core 2 top and forms puncture tip 21.The cut that puncture tip 21 is formed when guiding the cutting edge 20 of trident to break cyst cyst wall not easily closes, and drain is comparatively unobstructed.After the head end of puncture inner core 2 aligns with the head end of attraction sleeve pipe 1, at concordant 0 reference mark going out to attract sleeve pipe 1 tail end opening part to arrange paracentesis depth of puncture inner core 2, and puncture inner core 2 tail end after 0 scale arranges length mark scale, in order to read penetration depth during the 2 pairs of cyst cyst wall punctures of puncture inner core, improve safety when using, avoid puncturing dark.
Maloperation during in order to avoid using, arranges safety cock at described puncture inner core 2 tail end.The method to set up of safety cock is a lot, presents just a kind of embodiment explanation.The tail end of described puncture inner core 2 arranges security card slot 23, arranges safe kelly 22 in corresponding security card slot 23 by rotating shaft.When not using, one end of safe kelly 22 is given prominence in security card slot 23 outer and hold at the caudal end egress tube wall attracting sleeve pipe 1, makes puncture inner core 2 carry out puncture procedure.When needing puncture, oppress one end that safe kelly 22 gives prominence to security card slot 23, make whole safe kelly 22 enter security card slot 23 completely, no longer hold the tube wall attracting sleeve pipe 1, thus can puncture procedure be carried out.
As shown in Fig. 2, Fig. 3 and Fig. 6, described attraction sleeve pipe 1 is hollow pipe, and its head end arranges the bionical sucker 3 of annular Hirudo along transverse section tube wall annular axis.For ensureing sealing when Hirudo bionical sucker 3 is adsorbed on cyst cyst wall, the width of the bionical sucker 3 of described Hirudo should be less than the tube wall width attracting sleeve pipe 1, make the Hirudo bionical sucker edge of 3 one weeks concordant, be adsorbed on cyst cyst wall during convenient operation, reduce and stay apertured possibility.The material of soft quality preferably selected by described attraction sleeve pipe 1 manufactured materials, but the requirement of material itself is not high, and hard material also can.As shown in Figure 5, the bottom of the bionical sucker of described Hirudo 3 arranges some for providing the passage negative pressure conducting tube 4 of negative pressure for the bionical sucker 3 of Hirudo along attracting sleeve pipe 1 tube wall, negative pressure conducting tube 4 is passed through by the air sucking-off of bionical for Hirudo sucker 3 in negative pressure booster source 5, thus is adsorbed on the cyst wall of cyst by bionical for Hirudo sucker 3.
The embodiment in negative pressure booster source 5 has many kinds, and presents just Fig. 2 and Fig. 3 two embodiments illustrates:
As shown in Figure 2, described negative pressure booster source 5 comprises and to seal the indeformable hollow cylindrical discharge chamber 51 be communicated with, bleed check valve 52 and the exhaust check valve 53 with discharge chamber 51 and extraneous connecting pipeline that are arranged on negative pressure conducting tube 4 and discharge chamber 51 connecting pipeline with described negative pressure conducting tube 4.The piston 54 of coupling is set in described discharge chamber 51, the air in bionical for Hirudo sucker 3 can be entered discharge chamber 51 through check valve 52 suction of bleeding and discharge discharge chamber 51 to extraneous through exhaust check valve 53 when described piston 54 moves back and forth in discharge chamber 51.
Circulated to discharge chamber 51 by negative pressure conducting tube 4 in the described unidirectional direction of check valve 52 of bleeding, outwardly circulated by discharge chamber 51 in the unidirectional direction of described exhaust check valve 53.
The operation principle of the present embodiment is: when piston 54 is movable away from check valve 52 of bleeding in discharge chamber 51, exhaust check valve 53 is closed, check valve 52 of bleeding is open, and the air pressure of discharge chamber 51 declines, and the gas in the bionical sucker 3 of Hirudo and negative pressure conducting tube 4 is sucked and enters discharge chamber 51.When piston 54 adverse movement, check valve 52 of bleeding is closed, and exhaust check valve 53 is open, and the air pressure of discharge chamber 51 raises, and the gas of discharge chamber 51 is discharged extraneous.So, piston reciprocating is movable, and the negative pressure of the bionical sucker 3 of Hirudo is established.
As shown in Figure 3, described negative pressure booster source 5 comprises and to seal the elastically deformable housing 50 be communicated with, bleed check valve 52 and the exhaust check valve 53 with deformable housing 50 and extraneous connecting pipeline that are arranged on negative pressure conducting tube 4 and deformable housing 50 connecting pipeline with described negative pressure conducting tube 4.Described deformable housing 50 forced compression is out of shape and gets loose when restoring and the air in bionical for Hirudo sucker 3 can be entered deformable housing 50 through check valve 52 suction of bleeding and discharge deformable housing 50 to extraneous through exhaust check valve 53.
Circulated to deformable housing 50 by negative pressure conducting tube 4 in the described unidirectional direction of check valve 52 of bleeding, outwardly circulated by deformable housing 50 in the unidirectional direction of described exhaust check valve 53.
Operation principle is: when deformable housing 50 is by compression, gas pressure in deformable housing 50 is greater than the gas pressure in negative pressure conducting tube 4 and the external world, and now, check valve 52 of bleeding is closed, exhaust check valve 53 is open, and the gas in deformable housing 50 discharges the external world through exhaust check valve 53; When unclamping deformable housing 50, deformable housing 50 is expanded and is recovered luv space under natural resiliency restitution, air pressure in deformable housing 50 diminishes, air pressure in deformable housing 50 is less than the gas pressure in negative pressure conducting tube 4 and the external world, now, so, exhaust check valve 53 is closed, check valve 52 of bleeding is open, and the gas in the bionical sucker 3 of Hirudo and negative pressure conducting tube 4 is sucked and enters deformable housing 50.Operate and so forth, the negative pressure of the bionical sucker 3 of Hirudo is established.In this principle, the size of the negative pressure of the bionical sucker 3 of Hirudo is about due to the recovery tension force of deformable housing 50 self, and the larger peak suction value that can reach of tension force is larger, and the less peak suction value that can reach of tension force is less.
Certainly, the adoptable detailed description of the invention in negative pressure booster source 5 is a lot, is not repeating one by one herein.In concrete operation, often need to the capsule liquid sampling in cyst to carry out the subsequent survey such as pathological diagnosis or antibacterial culturing.For convenience of sampling, mouth-shaped and size and injector for medical purpose liquid outlet coupling in described attraction interface 6, when needing sampling, only need syringe liquid outlet to be connected on and attract, on interface 6 internal orifice, to extract appropriate capsule liquid.Certainly, sampling the work best opportunity is after cyst puncture cut and before capsule liquid suction decompression.
In a word: the present invention for liquid cyst decompression drainage, utilizes the bionical attraction bobbin seal of Hirudo of band Ring like suction disc mouth to be adsorbed on cyst outer wall, punctures from attraction cannula cavity, sample and decompression drainage cyst in laparoscopic surgery.Easy and simple to handle, when can avoid puncture decompression, capsule liquid outflow contaminated operation is wild, and convenient sampling, can also reduce the clear water flushing work after cyst excision again, and structure is simple, safe and reliable.
