Wherein holder comprises supporting seat 101 and guide 102; Holder is provided with opening, is provided with ball-type groove in the middle part of described opening, ball-type groove inside is provided with guide, and the guide Yanzhong heart is provided with pilot hole, and guide side is provided with open slot, and open slot is connected with pilot hole;
Wherein service aisle comprises and being made up of channel 301 and holder 302, service aisle is also connected with limiter, channel outer wall is also provided with scale strip, and wherein limiter 6 is connected to form by the knob 601 of female thread and externally threaded sleeve 602, and sleeve one end is also provided with scale;
Wherein perforator comprises and being connected to form successively by handle 201, mobile jib 202 and self-tapping screw 203, handle one middle side part is provided with groove, rotating seat 204 is provided with in groove, rotating seat one end is provided with projection, projection is connected with passage base 205 inner thread, passage base is connected with groove top by holder 206, and passage base, mobile jib are connected successively with self-tapping screw;
Wherein soft tissue pincers comprise rifle body 401, rifle body is provided with rifle bolt 402, straight tube 403 and ram seat 404, clip device 406 is provided with in straight tube, ejector sleeve 405 is provided with in clip device, ejector sleeve is connected with ram seat, clip device is connected with rifle bolt, and clip device is made up of upper grip and lower chuck, and lower chuck structure is spoon shape;
Wherein bony tissue forceps comprises tailstock 501, tailstock top is provided with slides cap 502, slide cap front end and be provided with guide pipe 503, guide pipe inside is provided with clipper 504, clipper is connected with rifle bolt 2 505, and rifle bolt two is connected with tailstock, and clipper front end is set to hook-shaped, and hook-shaped angular range is 90 degree to 135 degree, is also provided with clipper active tunnel 506 in guide pipe.
The end of straight tube and guide pipe is provided with scale strip, conveniently observes operational depth.
The operation principle of the present embodiment is as follows:
During use, all instruments all should be aseptic, first determines the patient body-surface position of percutaneous puncture, after medical science sterilization, service aisle is connected with perforator, is positioned over the position needing puncture, then pressed down by puncture handle force, skin histology is punctured, holds due to power and be difficult to control, so be also provided with rotating seat on perforator, rotate rotating seat, rotating seat drives the motion of passage base, realizes fine setting, realize paracentesis depth accurately by screw thread.Service aisle is touched after puncture terminates, the position of having punctured can be inserted, then by holder by opening and open slot, holder is stuck on channel, so just can ensure the problem of service aisle position movement all around, then limiter is fixed on channel, mutually abuts with holder and holder, ensure the degree of depth restriction of service aisle like this.
Fixing step can implement operation technique after finishing, and bony tissue forceps is goed deep into affected part vertebral plate position, carry out clip to osseous tissue, pinching rifle bolt two, clipper is shunk back, and returns in clipper active tunnel, and clipper closes, and gripping osseous tissue can complete.Because Bone density is high; hard; the capacity restriction of bony tissue forceps; sometimes all cannot cut disposable for affected part osseous tissue; and in order to the precision of performing the operation; so the piecemeal gripping of meeting usually; guarantee can not cause secondary injury to patient; so guide pipe diameter of the present utility model is greater than clipper active tunnel; the osseous tissue of such fritter can be filled within the space of guide pipe and clipper active tunnel after shearing retraction by hook-shaped clipper; bony tissue forceps's operation need not be extracted, convenient and practical.And clipper is set to hook-shaped, after clip, energy of retraction forms a towing force, ensures that osseous tissue can push in guide pipe smoothly, ensure that the time of clamp osseous tissue.After use terminates, owing to sliding cap and tailstock is clamping, so easily take off, by the mode slided, taken off from clipper sliding channel by the guide pipe sliding cap and front end fixing, the osseous tissue filling in guide pipe and clipper active tunnel in operating like this can take out, easy to operate.
Sting except after part vertebral plate, soft tissue can be used to clamp to be stung except tissues such as the ligamenta flava thickened, during use, to hold with a firm grip rifle bolt, the clip device closed (clip device normality is open configuration) that inside is arranged, prevent its hetero-organization from entering and cut mouthparts, cause danger, after closed, also conveniently enter through service aisle, after arriving soft tissue position, unclamp rifle bolt, clip device returns to normal and opens, and then with the ligamenta flava thickened of mode clamp affected part of occlusion, then pinching is held with a firm grip rifle bolt, clip device bounces back, and enters straight tube.To exert pressure ram seat, locking clip device, can not move, after exiting passage from straight tube, unclamp rifle bolt, promote ram seat, in clip device, the soft tissue such as ligamenta flava is ejected by ejector sleeve, and then rifle bolt of holding with a firm grip, clip device bounces back, enter straight tube, service aisle can be iterated through and repeatedly enter in patient body, the soft tissues such as the ligamenta flava that clamp thickens.Owing to reducing penetration damage, service aisle internal diameter is little, is closed in straight tube so the clip device opened can only be formed, and the structure energy more soft tissue of clamp of spoon shape, avoids tearing dural sac, injured nerve, operate safer, more convenient.
Repeat aforesaid operations at different disease sites, what can realize different parts is micro-wound pressure-reduced, and canalis spinalis expands, and patients symptomatic improves.
The disposable percutaneous puncture Canal expansive laminoplasty suit of one described in the utility model, there is good market prospect, by the mode of Wicresoft, to be down to minimum to the operation wound of patient, and handling safety, the operating time shortens, and does not need general anesthesia, decrease hemorrhage, the operating time of patient, patient's later stage is recovered to have good help.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
