Abstract
The utility model discloses a minimally invasive surgery's bone cement infusion device relates to the technical field of orthopedic medical equipment. It is equipped with the push rod of plug including needle tubing, one end, the plug in the push rod and with needle tubing inner wall sliding sealed fit, needle tubing side left end symmetry is fixed with two pull rings, and the needle tubing right -hand member is fixed with the decurrent notes pipe of slope, and the right -hand member lower part side of needle tubing is fixed with shock dynamo, shock dynamo manages axial lead between them at the coplanar with notes, needle tubing and notes spigot end of pipe lie in the lower tip of needle tubing cross section. The beneficial effects of the utility model are that: can avoid injecting in bone cement in -process pours into the bubble into bone, increase the successful type and the reliability of operation, effectually avoid the probability that the secondary performed the operation.
Description
Technical field
This utility model relates to the technical field of orthopaedic medical treatment equipment.
Background technology
Compression fracture of vertabral body is the modal complication of sufferers of osteoporosis face, and the large complication of open operation treatment wound is in the past many.And percutaneous vertebroplasty and Percutaneous kyplasty are spinal surgery development in recent years novel micro-wound surgical operations rapidly, directly injected in compressed vertebral by percutaneous or first to be reinjected the implant such as bone cement, artificial bone by balloon expandable, thus strengthen the mechanical stability of pathological changes vertebral body, clinical practice has confirmed its reliable and stable, rapid effective therapeutic effect, and few intercurrent disease.And bone cement injector is in micro-wound surgical operation, for what use in vertebral body filling bone cement process, common bone cement injector, easily there is bubble in the bone cement of filling, greatly have impact on surgical effect, and the note pipe of usual bone cement injector is elongated not, larger on the impact such as cortex, periosteum, cause wound comparatively large to patient body, the chemical property of its material is also stable not.
Utility model content
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provides a kind of bone cement injector of micro-wound surgical operation; Can avoid in injection bone cement process, bubble being injected in bone, add successful type and the reliability of operation, effectively avoid the probability of second operation.
The technical solution adopted in the utility model is: the bone cement injector providing a kind of micro-wound surgical operation, the push rod that it includes needle tubing, one end is provided with plug, and plug is in push rod and coordinate with needle interior wall slipper seal; Needle tubing side left end is symmetrically fixed with two draw rings, the note pipe under needle tubing right-hand member is fixed with and is tilted to, and the right-hand member lower side of needle tubing is fixed with vibration motor; The axial line of vibration motor and note pipe is at same plane; Needle tubing is positioned at the bottom of needle tubing cross section with the interface of note pipe.
Further optimization the technical program, the bone cement injector of micro-wound surgical operation is communicated with flexible pipe at the end of note pipe; The end of flexible pipe is communicated with tip note pipe, and tip note pipe top is fixed with lever.
Further optimization the technical program, the bone cement injector of micro-wound surgical operation is evenly carved with in the longitudinal direction at push rod measures screw thread, and push rod right-hand member and plug rotate and be socketed; The left end of needle tubing is screwed with swivel nut, measures screw thread and coordinates with swivel nut.
Further optimization the technical program, the bone cement injector of micro-wound surgical operation has polytetrafluorethylecoatings coatings in the surface-coated of tip note pipe.
Utility model is compared with traditional bone cement injector, its beneficial effect is: 1, open vibration motor, press push rod, bone cement is injected sutura by note pipe, is about to inject the bone cement in bone because vibration motor constantly shakes, bubble is wherein moved toward other parts, guarantee that the bone cement injected in bone does not have bubble, add successful type and the reliability of operation, effectively avoid the probability of second operation, patient is fully recovered sooner, better.2, note pipe and tip note pipe are connected by flexible pipe, and making tip note pipe has had larger operating range and angle, considerably increases the application conditions of utility model; Lever can facilitate healthcare givers to operate utility model, accelerates operation progress, reduces operating difficulty.3, measure screw thread to coordinate with swivel nut, by rotating push rod, plug is advanced, accurately can control the amount injecting bone cement, injection process is more stablized, is more accelerated.4, tip note pipe top layer scribbles politef, and this kind of material has antiacid alkali resistant, and its coefficient of friction is extremely low, and institute is so that use when performing the operation.

In Fig. 1,1, needle tubing; 2, draw ring; 3, push rod; 4, note pipe; 5, vibration motor; 6, flexible pipe; 7, tip note pipe; 8, lever; 9, plug; 10, screw thread is measured; 11, swivel nut.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, the bone cement injector of micro-wound surgical operation, the push rod 3 that it includes needle tubing 1, one end is provided with plug 9, plug 9 is in push rod 3 and coordinate with the slipper seal of needle tubing 1 inwall; Needle tubing 1 side left end is symmetrically fixed with two draw rings 2, the note pipe 4 under needle tubing 1 right-hand member is fixed with and is tilted to, and the right-hand member lower side of needle tubing 1 is fixed with vibration motor 5; The axial line of vibration motor 5 and note both pipes 4 is at same plane; Needle tubing 1 is positioned at the bottom of needle tubing 1 cross section with the interface of note pipe 4.The end of note pipe 4 is communicated with flexible pipe 6; The end of flexible pipe 6 is communicated with tip note pipe 7, and tip note pipe 7 top is fixed with lever 8.Push rod 3 is evenly carved with in the longitudinal direction measures screw thread 10, and push rod 3 right-hand member and plug 9 rotate and be socketed; The left end of needle tubing 1 is screwed with swivel nut 11, measures screw thread 10 and coordinates with swivel nut 11.The surface-coated of tip note pipe 7 has polytetrafluorethylecoatings coatings.
As shown in the figure, it should be noted that, utility model is when specifically using, first swivel nut 11 is screwed down, push rod 3 is pulled out needle tubing 1, then in needle tubing 1, bone cement is injected, the injection rate of bone cement should be greater than and need use amount, so just can guarantee that the bubble in bone cement can fully shake out by vibration motor 5, after injection, installing utility model will, rotating push-rod 3, piston 9 is mobile in needle tubing 1, vertical needle tubing 1, air in needle tubing 1 is got rid of, be rotated further push rod 3, just can start to carry out bone cement injection to have performed the operation, after having performed the operation, fully should clean note pipe 4, flexible pipe 6, tip note pipe 7, needle tubing 1, guarantee utility model safe and sanitary.
