The utility model discloses simple structure, the design is compact, and convenient to use, fixed cover can make the puncture ware fix the position of putting into of guaranteeing the puncture ware in the incision outside putting into the in -process, and the setting of spiral pipe can be broken the ring and can make fixed cover and the separation of sheath pipe in the bending of laparoscopic surgery chinese side stool pot tool in the sheath pipe, and cross infection is avoided for disposable to the sheath pipe, and sanitation and safety is good.
Description
Technical field
This utility model relates to a kind of flexible pipe perforator for endoscope-assistant surgery, belongs to technical field of medical instruments.
Background technology
Along with the continuous progress of medical technique level, endoscope-assistant surgery is more and more general in surgery.Conventional thoracoscopic operation needs to open 3-4 minimal incision * at chest, insert multiple perforator, for the placement of operating theater instruments and camera lens, but the pipe sheath of the perforator used in existing endoscope-assistant surgery is hard tubulose, in operation process operating theater instruments if desired certain angle use time, the pipe sheath of operating theater instruments and perforator produces larger friction and causes and use inconvenience, and perforator can not stomach wall fixedly cause perforator to stretch into abdominal cavity or thoracic cavity again crosses dark or deviate from external, affect operation technique, cause operating time to extend or complication increase.
Summary of the invention
The purpose of this utility model be in order to solve in endoscope-assistant surgery operating theater instruments because of need movable use to certain angle time and the pipe sheath of perforator produce larger friction and cause awkward problem, provide a kind of structure simple, the flexible pipe perforator for endoscope-assistant surgery compact to design.
This utility model adopts following technical scheme: a kind of flexible pipe perforator for endoscope-assistant surgery, comprise sheath pipe and puncture needle, the centre of described sheath pipe is set to serpentine pipe, one end of described sheath pipe is arranged with the fixed cover for being fixed on by sheath pipe outside otch, inner sleeve is provided with in described fixed cover, sealing ring is provided with in described inner sleeve, one end of described puncture needle is set to tip-shape, the other end of described puncture needle is provided with puncture cap, the end of described sheath pipe is provided with breaks ring, described in break ring around sheath pipe end arrange for by sheath pipe end section from.
Further, the inner side of described fixed cover is provided with groove, and described inner sleeve arranged outside has the flange that can embed groove, and described fixed cover and inner sleeve are flexibly connected by groove and flange.
Further, the end caliber of described sheath pipe is taper.
Further, described sheath pipe is that PE material is made.
Further, described fixed cover, inner sleeve and puncture needle are that medical stainless steel material is made.
This utility model structure is simple, compact to design, easy to use, fixed cover can make perforator insert in process the implantation site being fixed on and ensureing perforator outside otch, in sheath pipe, the setting of serpentine pipe can facilitate the bending of apparatus in endoscope-assistant surgery, and break ring and fixed cover can be made to be separated with sheath pipe, sheath pipe is single use, avoid cross infection, wholesomeness is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figs 1 to 6, a kind of flexible pipe perforator for endoscope-assistant surgery, comprise sheath pipe 1 and puncture needle 2, the centre of sheath pipe 1 is set to serpentine pipe, one end of sheath pipe 1 is arranged with the fixed cover 3 for being fixed on by sheath pipe 1 outside otch, the end caliber of sheath pipe is taper, inner sleeve 4 is provided with in fixed cover 3, the inner side of fixed cover 3 is provided with groove, inner sleeve 4 arranged outside has the flange that can embed groove, fixed cover 3 and inner sleeve 4 are flexibly connected by groove and flange, sealing ring 5 is provided with in inner sleeve 4, the setting of sealing ring 5 can ensure good pneumoperitoneum good airproof performance in operation process, one end of puncture needle 2 is set to tip-shape, the other end of puncture needle 2 is provided with puncture cap, the end of sheath pipe 1 is provided with breaks ring 6, break ring 6 to arrange for by sheath pipe 1 end separating around the end of sheath pipe, sheath pipe 1 is made for PE material, fixed cover 3, inner sleeve 4 and puncture needle 2 are made for medical stainless steel material.
Using method: in endoscope-assistant surgery, first carry out disinfection and otch at given surgical position, then the perforator sheath pipe 1 being arranged with fixed cover 3 is inserted in otch, fixed cover 3 is placed in outside otch, the corrugated tubing that PE material is made can make apparatus and photographic head in operation process bend certain angle, make instrumentation more convenient, after operation sheath tube end broken ring 5 tear fracture, namely sheath tube end is separated with sheath pipe, fixed cover 3, after inner sleeve 4 and puncture needle 2 can reclaim sterilization, secondary uses, and fixed cover do not contact with used sheath pipe clean after safety and sanitation better, sheath pipe is single use.
