Abstract

The utility model discloses a simple MEEK skin cutter, which comprises a cover with 13 gaps and a pyramid base platform; the cork with the leather sheet is detachably fixed on the pyramid base platform, and the cover is detachably buckled on the pyramid base platform. The simple MEEK skin cutting equipment material has a simple structure and very low price and cost.

Description

Simple MEEK skin cutter

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to simple and easy MEEK skin cutter of surface of a wound MEEK skin grafting technique.

Background

The existing MEEK micro skin graft transplantation technology is a very effective skin grafting operation mode in clinic, wherein the key of the whole set of equipment is a MEEK skin cutter. The prior MEEK skin cutter can cut 4.2cm multiplied by 4.2cm skin sheets into 196 pieces of miniature skin sheets of 3cm multiplied by 3cm by two times in length and breadth, but the equipment has some defects. The price is very expensive, the system is difficult to be widely developed in primary hospitals all over the country, and the system needs to pay huge cost when being applied to animal experiments; the cleaning and disinfection procedures are complex, the lubrication and maintenance need cost, and the lubrication and maintenance can be completed by specially trained personnel; the blade directly contacting the skin piece is used as an invasive sharp instrument for repeated clinical use, which may be a medium causing cross-spread of diseases, and the repeated disinfection and repeated use can cause the blade to become dull and affect the operation.

Disclosure of Invention

In order to overcome the shortcomings of high price cost, complex mechanical equipment, clinical repeated use and the like in the prior art, the utility model provides a simple MEEK skin cutter with simple structure, which can achieve the same skin cutting effect.

The utility model discloses a realize through following scheme:

the utility model provides a technical scheme that its technical problem adopted is: a 'cover' with 13 gaps and a pyramid base 'platform' are designed, a cork adhered with a leather sheet is detachably fixed on the 'platform' (2), and the 'cover' (1) is detachably buckled on the 'platform' (2).

The inner diameter of the bottom surface of the cover is 42mm multiplied by 42mm square, and the thickness of the bottom surface is 2-5 mm; the four edges are edges with the thickness of 1-3mm, the height is 7-10mm, and the inner depth of the cover is about 5 mm. The cover is provided with 13 parallel hollows with the gaps of 0.2-0.6mm, the distance between the central lines of the adjacent gaps is 3mm, two ends of each gap reach the edges at two sides and form the hollows on the edges, and the depth of the gaps formed on the edges exceeds the thickness of the bottom surface by 2-4 mm. Two edges parallel to the 13 slits are respectively provided with an arc-shaped defect, the size of the arc-shaped defect is similar to the radian of a thumb nail of an adult, and the top point of the arc is close to the bottom surface of the cover.

The shape of the platform is similar to that of a pyramid, the upper side and the lower side of the platform are both square, the side length of the square on the upper side is 42mm, the side length of the square on the lower side is 42mm, the side length of the square is larger than 42mm, the platform is not specific, the upper part is small, the lower part is large, and the platform can be placed on a plane to keep a stable state in principle. The square on the upper surface needs to form a cuboid with a certain thickness, the horizontal plane of the cuboid is the square with the side length of 42mm, and the height of the cuboid is not less than the internal depth of the cover, generally about 5 mm.

The material of the "lid" may be metal such as aluminum alloy and stainless steel, or organic compounds such as plastic and resin, or other hard materials.

The beneficial effects of the utility model are that, the material is simple, simple structure, and preparation processing is convenient, and the cost reduces to several hundred yuan from tens of thousand yuan, and the ordinary low-priced blade of circular roller bearing blade that the supporting was used is favorable to popularizing and applying the miniature skin graft of MEEK technique in the poor area of whole nation and the less medical institution of burn patient. This simple and easy MEEK skin grafting machine and blade are disposable, make into the product and disinfect the back and encapsulate in aseptic packaging bag, according to waste disposal after the use, have avoided complicated dismantlement disinfection and lubrication maintenance, have avoided long-term used repeatedly to make the cutting edge dull, have avoided becoming the disease alternately-the transmission medium.

Drawings

FIG. 1 is a structural view of a "lid" having 13 slits according to the present invention

Fig. 2 is a structural diagram of the pyramid base "platform" of the present invention.

Detailed Description

During operation, a leather sheet taken by a leather supply area is attached to a square cork (a consumable material special for MEEK skin grafting operation) with the side length of 42mm, the cork with the leather sheet is placed on a platform 2, a cover 1 is buckled, a roller blade is used for cutting along each gap, after 13 times of cutting, the cover 1 and the cork are taken down, the cork is rotated for 90 degrees and placed on the platform 2, the cover 1 is covered, and the cutting is carried out again for 13 times. After the cover 1 and the cork stopper are taken down, 196 small square skin sheets with the sides of 3mm can be seen, and the subsequent operation steps are the same as the operation specifications of the MEEK micro skin sheet transplantation technology.

Claims

1. The utility model provides a simple and easy MEEK skin cutter which characterized in that: comprises a 'cover' (1) with 13 gaps and a 'platform' (2) of a pyramid base; the cork with the leather sheet is detachably fixed on the pyramid base platform (2), and the cover (1) is detachably buckled on the pyramid base platform (2).
