Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in figures 1 to 6:

A kind of joint capsule cutter external member, including joint capsule cutter 1 and cutter protective case 2, the joint capsule cutter 1 include Operation handle 11 and cutter knife bar 12, the cutter knife bar 12 are fixed in operation handle 11, and the cutter knife bar 12 is cylinder Structure, the cutter protective case 2 include protective case main body 22 and disassembly pull ring 21, and 22 shape of protective case main body is top band The lower end of protective case main body 22 and vertical with protective case main body 22 is arranged in the hollow cylinder of circular cone, the disassembly pull ring 21, The disassembly pull ring 21 is D font.

12 top of cutter knife bar be equipped with sword type function part 13,13 two sides of sword type function part put the first edge on a knife or a pair of scissors and with cutter knife Bar 12 is smooth to be fixedly connected, and the 13 top blade tip part of sword type function part is semicircle, cuts more smooth when tissue, angle choosing Take range relatively large, the structure that thicker two sides, that is, semicircle head end puts the first edge on a knife or a pair of scissors among the sword type function part 13 can guarantee that function part is strong Degree will not be equipped with item with disassembly 21 relative position of pull ring in the protective case main body 22 situations such as operating process is broken Shape dismantles mouth 23, the bar shaped dismantle mouth 23 from 22 bottom end entrance of protective case main body extend to 22 one third of protective case main body to Position between half is equipped with V-type inside the protective case main body 22 and dismantles slot 24, described V-type disassembly 24 one end of slot and item Shape disassembly mouth 23 other end that connects extends to taper endvertex, facilitates protective case to dismantle, inside 22 upper end of protective case main body Equipped with sword type function part protective case 25,25 shape of sword type function part protective case and sword type function part 13 coincide, and prevent from operating Protective case and cutter are subjected to displacement variation, the disassembly pull ring 21 and bar shaped disassembly 23 place plane of mouth and sword type function when external member Face where the non-blade in portion 13 is parallel, and protective case is smoothly split from bar shaped disassembly mouth 23 to conical insertion end top when easy to disassemble, into One step, V-type disassembly slot 24 is bonded with sword type function part side edge, insertion end top one when can more effectively guarantee to dismantle protective case Side is split, and protective case is facilitated to extract from articular cavity, and the operation handle 11 is opposite with hand-type is held to coincide, and it is convenient to hold, and keeps away Exempt to slide.

Working principle: in use, the joint capsule cutter 1 that will be cased with cutter protective case 2, i.e. joint capsule cutter external member are from pre-cut Good approach notch is inserted into articular cavity, and after being inserted to suitable position, a hand-held joint capsule cutter 1, the other hand pulls pull ring 21, cutter Protective case can from disassembly 23 side of mouth tear, and then from approach extract abandon, it is easy to use, effectively reduce medical treatment at This, improves procedure efficiency.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
