Skin graft cutting device

Abstract

The invention relates to a skin graft cutting device. The skin graft cutting device comprises a skin graft cutting mechanism, a three-dimensional moving mechanism and a base, wherein the skin graft cutting mechanism cuts a skin into a shape meeting the skin grafting operation requirement; the three-dimensional moving mechanism holds the skin graft cutting mechanism and comprises an X-axis moving assembly, a Y-axis moving assembly and a Z-axis moving assembly, and therefore the skin graft mechanism can be moved in the X, Y and Z-axis directions orthogonal to one another; and the three-dimensional moving mechanism is arranged on the base. The skin graft cutting device is wide in application range, easy and convenient to operate, adjustable in size specification of a pull net and the skin, uniform in particle shape, high in activity retention and particularly suitable for being used in various skin grafting operations.

Description

technical field [0001] The present disclosure generally relates to the field of skin grafting, and in particular relates to a skin graft cutting device. Background technique [0002] At present, the treatment of extremely large and deep burns is still a major challenge for clinicians. Timely wound repair is one of the keys to improving the success rate of treatment. If a patient with a large area of ​​deep burn cannot seal the wound in the early stage, it will bring great difficulties to the follow-up treatment. Therefore, how to use limited skin donor sites to repair large-area deep wounds and ensure the survival rate of grafts is an urgent problem to be solved in the treatment of critically ill burn patients. [0003] Existing skin grafting methods can be divided into mesh skin grafting, postage stamp skin grafting, particle skin grafting, etc. according to the shape of the skin graft, all of which require the use of special equipment for skin graft preparation. Mesh sk...

AI Technical Summary

Problems solved by technology

Mesh skin grafting requires the use of a mesh skin grafting machine, but the distance between the mesh of the mesh skin grafting machine is relatively fixed and cannot be adjusted flexibly according to the wound surface, and the postoperative appearance is not very beautiful

The representative MEEK skin grafting in postage stamp skin grafting requires the use of MEEK skin grafting machine, but the cleaning and disinfection procedures of MEEK skin grafting machine are complicated and require specially trained personnel to operate, and the blades are expensive. If repeated use in clinical practice may cause cross-infection of diseases , In addition, after repeated disinfection and repeated use, the dullness of the blade will affect the cutting effect

Microparticle skin grafting needs to use manual scissors or medical shredders. The manual cutting method is simple and convenient, and does not require special equipment, but it is time-consuming and laborious. It takes at least 2 people to cut for more than 30 minutes to achieve a size of less than 20mm x 20mm. 1mm 2 The preparation standard of particles, and the particle size is very uneven; although the rotary medical peeling machine can quickly prepare particle skins that meet the particle size in a short time, there are also problems of irregular particle size and extremely low particle activity
