Abstract

The invention discloses a kind of simple MEEK cuts skin device, this cuts skin device includes one apertured " lid " (1) and a base " platform " (2).The bottom surface internal diameter of " lid " is that 42mm × 42mm is square, and four sides are the rib for having certain thickness and height, and there is certain thickness bottom surface, the internal depth about 5mm of " lid ".13 parallel gaps are hollow out, and the distance between center line of adjacent slits is 3mm, and its two ends reaches the rib of both sides and hollow out is formed on rib, and hollow out depth exceedes bottom thickness.Respectively there is an arc defect with 13 two parallel ribs of gap.The shape of " platform " is similar with pyramid, is length of side 42mm square above, and here is larger square, and the up-small and down-big desktop that keeps flat has stability.Into certain thickness cuboid, the horizontal plane of cuboid is the square of the 42mm length of sides to square palpiform above, and which highly must not drop below the internal depth of " lid ".This simple MEEK cuts skin equipment material simple structure, and Costco Wholesale is very cheap.

Description

Simple MEEK cuts skin device

Technical field

The invention belongs to medical instruments field, and in particular to a kind of dermatome of wound surface MEEK skin-grafting technology

Background technology

Existing MEEK micro skin pieces implantation technique is a kind of clinically very effective skin grafting mode, wherein used To equipment set in key be MEEK dermatomes.Existing MEEK dermatomes can be by the skin graft Jing of 4.2cm × 4.2cm The miniature little skin graft that cutting twice in length and breadth forms 196 pieces of 3cm × 3cm is crossed, but in place of the equipment has some shortcomings.Its price is very It is expensive, it is difficult to extensively to launch in national basic hospital, be applied to zoopery and need to pay great cost；Its cleaning and sterilizing program is multiple Miscellaneous, lubricating maintenance needs cost, while needing the personnel of special training just complete；Wherein the knife edge of directly contact skin graft, makees Reuse in clinic for a kind of invasive sharp instrument, the medium for causing disease cross transmission may be become, repeatedly sterilization and Reuse can cause edges dull, affect operation technique.

The content of the invention

In order to overcome Costco Wholesale in prior art high, plant equipment is complicated, the shortcomings of clinically reuse, the present invention The simple MEEK for providing a kind of simple structure cuts skin device, can reach identical and cut bark effect.

The present invention is achieved by the following scheme：

The technical solution adopted for the present invention to solve the technical problems is：Design one " lid " (1) for having 13 gaps and One pyramid base " platform " (2).

The bottom surface internal diameter of " lid " (1) is that 42mm × 42mm is square, and bottom thickness is 2-5mm；Four edges are thickness 1- The rib of 3mm, is highly 7-10mm, and the internal depth of described " lid " (1) is 5mm or so.There are 13 to put down on described " lid " (1) Hollow out of the capable gap for 0.2-0.6mm, the distance between center line in adjacent gap is 3mm, its two ends reach the rib of both sides and Hollow out is formed on rib, the depth in the gap formed on rib exceedes bottom thickness 2-4mm.It is each with 13 two parallel ribs of gap An arc defect is made, the size of arc defect is similar with the radian of adult's thumbnail, and " lid " is pressed close on the summit of arc (1) bottom surface.

The shape of " platform " (2) is similar with pyramid, is square above and below, and the square length of side above is 42mm, here are big square, and its length of side is more than 42mm, concrete indefinite, up-small and down-big, places in principle and can protect in the plane Hold steady statue.Square palpiform above is the 42mm length of sides into certain thickness cuboid, the horizontal plane of cuboid Square, which highly must not drop below the internal depth of " lid ", generally 5mm or so.

The material of " lid " can be the metal such as aluminium alloy, rustless steel, alternatively organic compound such as plastics, resin etc. or its His hard material.

The invention has the beneficial effects as follows, material is simple, simple structure, and fabrication and processing is convenient, and cost is reduced from hundreds of thousands unit To hundreds of unit, the common cheap blade of matching used circular roller bearing blade, be conducive in nationwide poverty-stricken areas and burn patient Less medical institutions' popularization and application MEEK micro skin piece implantation techniques.The simple MEEK dermatomes and blade are disposable use Product, to be fabricated to after product carries out disinfection carry out being packaged in aseptic package bag, using rear by waste process, it is to avoid complicated tears open Unload sterilization and lubricating maintenance, it is to avoid long-term reuse causes edges dull, it is to avoid become disease cross transmission communication media.

Description of the drawings

In the accompanying drawings：Fig. 1. there are " lid ", the Fig. 2 in 13 gaps. pyramid base " platform ", Fig. 3. outside the axonometric chart of " lid " Face is seen, Fig. 4. and the axonometric chart inner face of " lid " is seen, Fig. 5. the axonometric chart of " platform " and " lid ", Fig. 6. the material object of " platform " and " lid " Figure, Fig. 7. the operating process figure of skin is cut with circular roller bearing knife.

Specific embodiment

In operation, the skin graft taken by skin donor site is affixed on into square cork (the MEEK skin graftings that the length of side is 42mm Supporting special consumptive material), the cork with skin graft is placed on " platform " (2), then (1) " will be covered " and buckled, with roller bearing blade edge Every gap is cut, and after completing 13 cuttings, removes " lid " (1) and cork, and 90 ° of cork of rotation is positioned over " flat Platform " (2), covers " lid " (1) and carries out 13 cuttings again.Remove i.e. visible 196 pieces of length of sides 3mm after " lid " (1) and cork The miniature little skin graft of square, working specification of the subsequent process steps with MEEK micro skin piece implantation techniques.

Claims

1. a kind of simple MEEK makes skin graft device, it is characterised in that：One " lid " (1) for having 13 gaps and a pyramid base are put down Platform (2) can be used to the skin graft of 4.2cm × 4.2cm will can be formed the micro- of 196 pieces of 3mm × 3mm through cutting twice in length and breadth The little skin graft of type.

2. skin is cut as described in claim 1, and operating process supports the use circular roller bearing blade and cuts skin, and and non-usage is common Knife blade, so as to " cover " during skin is cut (1) fasten post the cork of skin graft after can without being close to skin graft, in order to avoid Skin graft is pasted during separation.
