Abstract

The utility model relates to a puncturing cannula used on a transumbilical approach operation, comprising a puncture sheath, a puncture stabber, and an inner core with at least three operating passages, which is characterized in that one of the operating passages acts as a laparoscope passage, and at least two operating passages are used as the passages for soft apparatuses; the inner core can be arranged inside the puncture sheath, and an air leakage resistant device is arranged at the tail end of each operating passage of the inner core. The puncturing cannula has the advantages of enjoying simple structure and convenient operations, saving the space in a surgery as well as the equipment costs of the hospital, and facilitating a puncturing laparoscope operation.

Description

Through umbilicus approach operation puncture casing

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly discloses a kind of through umbilicus approach operation puncture casing.

Background technology

Along with the development of Minimally Invasive Surgical Technology, stomach wall does not have the cicatrix operation becomes the new target that people pursue.Its basic approach is through the operation of natural tract, promptly inserts soft scope through natural tract (stomach, rectum or vagina), and the otch by natural tract enters the abdominal cavity and undergos surgery.Thereby reach stomach wall and do not have cicatrix, postoperative pain lighter, Wicresoft, effect more attractive in appearance more.Yet this technical difficulty is very big, has problems such as abdominal cavity infection, complication chance of occurrence are many, even also has the risk of organ puncture hole fistula, and the apparatus of present clinical use also can't overcome its technical difficulty, awaits the further maturation of apparatus and technology.

Summary of the invention

The purpose of this utility model is to solve the problems of the prior art, provide a kind of simple in structure, save space, equipment cost low, be convenient to promote use puncture casing through the operation of umbilicus approach, greatly reduce technical difficulty and operation risk.

This utility model is achieved in that a kind of through umbilicus approach operation puncture casing, comprise puncture sheath, puncture awl, it is characterized in that: also comprise the inner core that is provided with at least three operating walk ways, one is that peritoneoscope passage, at least two are soft instrument channel in the operating walk way of described inner core; Described inner core can be inserted in the puncture sheath, and described inner core operating walk way tail end is provided with the gas-tight neglected loading and puts.

Described soft instrument channel tail end exposes the puncture sheath, and described soft instrument channel tail end place axis is parallel with inner core axes or intersect.

The gas-tight neglected loading of described inner core operating walk way tail end is changed to rubber cap.

The gas-tight neglected loading of described inner core operating walk way tail end is changed to silicon rubber cup.

The beneficial effects of the utility model are: 1. this utility model is inserted with peritoneoscope replacement scope and is carried out the wild illumination of art in the sleeve pipe inner core, can well solve the unmanageable problem of positive bit image under the scope, same surgical field of view when obtaining with laparoscopic procedure at ordinary times is more suitable for laparoscopic surgery doctor's operating habit; Wild brightness of art and image definition greatly strengthen than soft scope; Owing to need not use huge, numerous and diverse endoscopic assistance, save the space of operating room and the equipment cost of hospital; 2. two other passage of this utility model can be inserted two soft apparatuses and operated.3. this utility model is operated telescopic exploitation, has both reached the effect that stomach wall does not have cicatrix, has avoided again performing the operation with soft endoscopic technic problem, the problem includes: difficulty and problem through natural tract.For laying a good foundation, realized the laparoscopic surgery of a puncturing hole through carrying out of umbilicus approach operation.

The specific embodiment

According to Fig. 1～Fig. 7, this utility model comprises puncture sheath 1, puncture awl 2, inner core 3, and puncture awl 2, inner core 3 can insert respectively in the puncture sheath 1; Be provided with at least three operating walk ways in the inner core 3, wherein operating walk way is at least one peritoneoscope passage and at least two soft instrument channel, can place peritoneoscope in the described peritoneoscope passage, can place the operation technique apparatus in the described soft instrument channel, in this example, be provided with three operating walk ways in the inner core 3, an operating walk way is a peritoneoscope passage 7, and two other passage is soft instrument channel 8.Described inner core 3 operating walk way tail ends are provided with the gas-tight neglected loading and put, and described gas-tight neglected loading is changed to silicon rubber cup or rubber cap 9.Described soft instrument channel tail 6 ends expose puncture sheath 1, and described soft instrument channel tail end 6 place axis are parallel with inner core 3 place axis or intersect.

During use, cut earlier umbilicus lower edge skin to being fit to length, it is interior 1 that the awl 2 that will puncture is inserted the puncture sheath, and the place punctures at incision of skin.After entering the abdominal cavity, take out puncture awl 2, the controlled valve 5 on the puncture sheath 1 is closed.The intake valve 4 that wears long on the sheath of sting 1 connects the pneumoperitoneum apparatus air inlet pipe, and injecting carbon dioxide gas is kept abdominal pressure by pneumoperitoneum apparatus.Inner core 3 is inserted in the puncture sheath 1.The peritoneoscope that connects camera head is inserted the abdominal cavity through the peritoneoscope passage 7 of inner core 3, two soft operating apparatuss are inserted the abdominal cavity respectively through the soft instrument channel 8 of inner core 3, carry out the laparoscopic surgery operation.

This utility model is by the passage in the inner core, inserts peritoneoscope respectively and soft apparatus is operated, thereby finishes the laparoscopic surgery that only needs 1 handle hole.After umbilical notch cut was sewed up, stomach wall was not seen the operation cicatrix substantially, reached the purpose that stomach wall does not have the cicatrix operation.By the passage of this utility model sleeve pipe inner core, put peritoneoscope and replace scope, can well solve the unmanageable problem of positive bit image under the scope, same surgical field of view when obtaining with laparoscopic procedure at ordinary times is more suitable for laparoscopic surgery doctor's operating habit.Wild brightness of art and image definition greatly strengthen than soft scope.Owing to need not use huge, numerous and diverse endoscopic assistance, save the space of operating room and the equipment cost of hospital.Triple channel is operated telescopic exploitation, for laying a good foundation through carrying out of umbilicus approach operation.
