Abstract

A dermatome for skin burn grafting comprises a plurality of vertically-arranged cutters which have blades facing downward and which are fixed on a base with the blade exposed. The utility model is characterized in that at least one group of cutters are arranged in parallel to one another; and cutters are staggered horizontally and superposed partially, with superposed length being at least a quarter of the cutter's total length. When two groups of cutters are used, the two groups of cutters are arranged vertically to each other, forming cruciform structures, and the cruciform structures are superposed partially with the superposed length being at least a quarter of the cutter's total length. The utility model has the advantages of simplified operation, shortened operation time, ingenious design, simple structure, easy use, and high quality and efficiency of skin incision.

Description

A kind of dermatotome tool that is used for the grafting for burns operation

Technical field

This utility model relates to the dermatotome tool that uses in a kind of surgical operation, specifically is a kind of dermatotome tool that is used for the grafting for burns operation.

Background technology

Often need surgery skin grafting at the burn patient wound surface, operation divides big open skin-grafting, the skin-grafting of mesh graft cuticle sheet etc., and is wherein comparatively general with skin-grafting of small pieces skin and mesh graft.Cuticle sheet skin-grafting can be cut into a lot of fritters with a spot of skin, diffusible being implanted on the bigger wound surface, but cut skin, row requires great effort during skin-expenses, cicatrix is bigger behind the wound healing.Mesh skin graft skin-grafting is to cut out a plurality of otch by certain size, certain distance on the skin that takes off, then to around draw back skin and be netted, the area increase can be implanted on the wound.Mesh skin graft skin-grafting is owing to be that whole skin is planted in wound surface, and healing back cicatrix is interrupted, and cicatrization is lighter relatively, and is less to the influence of the limb activity after the healing, but mesh is bigger, and outward appearance is bad.The conventional mesh skin graft of making is usually with rolling the skin machine or the cutting of a manual cutter one cutter, and skin graft is not only thin but also soft, and hand cut is time-consuming, difficult quality guarantee.

Summary of the invention

The purpose of this utility model is the convenient and swift and high-quality a kind of dermatotome tool that is used for the grafting for burns operation that cuts out the otch that has mesh skin graft and cuticle sheet advantage concurrently on skin graft of a kind of energy of design.

The technical solution of the utility model is, a kind of dermatotome tool that is used for the grafting for burns operation, arranged vertical many downward blade of blade, blade is fixed on the pedestal upper knife edge and exposes, it is characterized in that at least one group of blade is parallel to each other, a blade and next blade interlace on every capable blade, and overlap, overlap length is at least 1/4 of blade lengths.

When adopting two groups of blades, it is overlapped that two groups of blades vertically are between "+", each "+" the position part mutually, and overlap length is at least 1/4 of blade lengths.

This utility model is with many blade to be fixed on the pedestal by the blade that rule is arranged downward vertically.Cutting during skin graft with this utility model application of force vertically downward, just can on skin graft, cut out simultaneously a plurality of standards, little skin graft and the bonded otch of mesh skin graft.This utility model adopts two groups of blades vertically to be the bonded dermatotome tool of little skin graft and mesh skin graft mutually.When adopting one group of blade, be the bonded secondary dermatotome of little skin graft and mesh skin graft tool.This utility model has been simplified operation process, protects expensive operating time for rescue patient has won, and be skillfully constructed, simple in structure, easy to use, can improve greatly and cut the cortex amount and cut skin efficient.

The specific embodiment

Embodiment 1 mesh skin graft and the bonded secondary dermatotome of little skin graft tool,

One group of arranged vertical has manyly the downward blade of blade (3) in frame (1), is that pedestal (2) is fixed blade with rapid solidification glue.Blade (3) is parallel to each other, and a blade and next blade interlace on every capable blade, and overlap, and overlap length is at least 1/4 of blade lengths, and overlap length is big, and propagation is big, and overlap length is little, and propagation is also just little, and overlap length designs as required, as Fig. 1.During use skin graft is tiled on the platform, this utility model is otch of the application of force vertically downward, cutter is revolved to turn 90 degrees again, and secondary cut just can cut out the mesh skin graft and the cuticle sheet otch of a plurality of standards simultaneously on skin graft.Can be designed to the blade and the different cutter of knife number of different size as required, also can be according to the thickness difference of skin graft, the Design of length that blade is exposed is the H=0.5-1.5 millimeter.

The bonded dermatotome tool of embodiment 2 mesh skin grafts and little skin graft,

Arranged vertical has many downward blade of blade (3) for two groups in frame (1), two groups of blades are vertical mutually, and blade (3) vertically is "+" mutually, respectively the position part is overlapped between "+", and overlap length is at least 1/4 of blade lengths, overlap length is big, propagation is big, and overlap length is little, and propagation is also just little, overlap length designs as required, just,, be made as pedestal (2) with metal blade is fixed as Fig. 3 with vertical mutually setting of cutter two covers of embodiment 1.During use skin graft is tiled on the platform, with this utility model application of force vertically downward, once cutting just can cut out the otch of a plurality of standards simultaneously on skin graft, and other structure is with real resistance example 1.

Claims

1, a kind of dermatotome tool that is used for the grafting for burns operation, arranged vertical many downward blade of blade (3), blade is fixed on pedestal (2) upper knife edge and exposes, it is characterized in that, at least one group of blade (3) is parallel to each other, a blade and next blade interlace on every capable blade, and overlap, and overlap length is at least 1/4 of blade lengths.

2, a kind of dermatotome tool that is used for the grafting for burns operation as claimed in claim 1 is characterized in that, two groups of blades (3) vertically are "+" mutually, respectively the position part is overlapped between "+", and overlap length is at least 1/4 of blade lengths.
