Abstract
The utility model relates to a medical cartilage grafting receptor cancellous bone bed former. The former is characterized in that a knife head base is connected with a connecting part; the connecting part is connected with a hand holding part; and the knife head base is connected with a plurality of knife edges. The former overcomes the defects that a bone cutting surface finished manually by a bone knife, a bone chisel and the like is uneven, the randomness is high, mismatching of a receptor bone cutting surface and a donor bone cutting surface is caused easily, and bone healing is not facilitated. The former can immediately accomplish receptor cancellous bone bed forming by hitting once, so that the forming efficiency is improved greatly, the operation time is shortened, the repeatability is very high, and the former can be reused; and the former can allow complete matching of the bone cutting form of a grafting donor cartilage cancellous bone and a receptor cancellous bone bed, so that a grafting donor can be completely matched with a receptor, and bone healing is facilitated.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of medical cartilage transplantation receptor spongy bone bed former.
Background technology
Before the present utility model, when bulk allogeneic cartilage is transplanted, under receptor cartilage, before the transplanting of spongy bone, be trimmed to manual operations, use osteotome, the simple tools such as osteotome.The osteotomy surface out-of-flatness of hand finish, random large, cause the form of each osteotomy surface inconsistent, and easily shine into receptor osteotomy surface and do not mate with donor osteotomy surface.General manual osteotomy is monoplane osteotomy, no matter spongy bone or receptor spongy bone bed is plane under donor cartilage, therefore, the contact area of donor and receptor is little, and the bone healing time of creeping substitution can be longer, is unfavorable for knitting.
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned defect, develops a kind of medical cartilage transplantation receptor spongy bone bed former
The technical solution of the utility model is:
Medical cartilage transplantation receptor spongy bone bed former, its technical characteristics is that cutter head pedestal connects connecting portion, and connecting portion connects Handheld Division, and cutter head pedestal connects multiple blades.
Curved concave surface before described cutter head pedestal, blade is along this arc-shaped concave spread configuration.
Described blade is isosceles triangle.
The tip of described multiple blades points to the center of circle of arc-shaped concave, or blade is on the normal of arc-shaped concave.
Advantage of the present utility model and effect are: 1. once hit the shaping at once completing receptor spongy bone bed, greatly improve forming efficiency, shorten operating time.2. can select corresponding shaping cutter head according to the radian of receptor cartilage surface.3. can select according to the form of spongy bone under donor cartilage the cutter head of corresponding knife edge angular.4. use this invention can make the receptor spongy bone bed form after each shaping be consistent, have high repeatability.5. this osteotomy clipper is all-metal construction, can repeatedly sterilize, and reuses.6. coordinate spongy bone wedge osteotomy clipper under donor cartilage, can make under transplantation donor cartilage form after spongy bone osteotomy mate completely with receptor spongy bone bed, thereby transplantation donor and receptor are fitted like a glove, be easy to bony union.
Brief description of the drawings
Fig. 1---this utility model structural principle schematic diagram.
Fig. 2---Fig. 1 top view.
In figure, each label corresponding component is as follows:
Blade 1, cutter head pedestal 2, connecting portion 3, Handheld Division 4.
Detailed description of the invention
As shown in Figure 1, 2:
Cutter head pedestal 2 connects (strike handle) connecting portion 3, connecting portion 3 connects (strike handle) Handheld Division 4, cutter head pedestal 2 curved concave surface above, on this arc-shaped concave, connect multiple blades 1, blade 1 is isosceles triangle, the tip of multiple blades 1 points to the center of circle of arc-shaped concave, or blade 1 is on the normal of arc-shaped concave, and all parts are metal material and make.
The explanation of this utility model application process:
The receptor graft area of spongy bone under cartilage to be formed is appeared, size and form, medical cartilage transplantation receptor spongy bone bed former that radian is suitable will be selected, the blade of forming-tool head end 1 is aimed to receptor spongy bone bed, operator holds Handheld Division 4, knock the end of Handheld Division 4 with peening hammer, the blade 1 of forming-tool head end embeds in spongy bone, removes shaping cutter head, and under cartilage, the receptor graft area of spongy bone forms continuously arranged wedge shape spongy bone bed.
The angle of blade 1, length have many styles, and concave surface radian, length and the width of cutter head pedestal 2 has many styles to select.
