Description

Cone skin taking device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a cone skin taking device.

Background

In the field of burn plastic surgery, autologous skin grafting is a main treatment operation. Since the particle skin grafting method which is known as Chinese grafting method at home and abroad in 1985 provides revolutionary development for burn clinic, no substantial progress is made to the current skin grafting. At present, the autologous skin grafting can be divided into a full-thickness skin grafting method, a fault skin grafting method (further divided into a blade-thickness skin grafting method and a medium-thickness skin grafting method according to the thickness) and a particle skin grafting method. Since the nature of autologous skin transplantation is that the patient himself takes the treatment method of 'removing east wall and filling west wall', we have to take the gains and losses of the skin receiving area and the skin supplying area into consideration. For large-area burn patients, the knife-thick skin grafting method and the particle skin grafting method are widely applied clinically because the damage to the skin supply area is small. But many clinicians will have such experience: after the skin grafting of a large-area patient, the contracture of the blade-thick skin graft is much more serious than that of the microsomal skin.

We have discovered, by summarizing the results of many studies at home and abroad and many clinical practices we have done by themselves: the mechanism by which contractures in knife-thick graft are more severe than those of microsomes should include the following three aspects: 1) the influence of the contact plane direction of the graft and the skin tissue; 2) when the autologous dermal tissue is embedded into the repair tissue, the scar hyperplasia can be inhibited through the action of autologous fibroblasts to relieve the skin contracture; 3) wound healing is a complex biological process, and relates to the processes of proliferation, migration, differentiation, apoptosis and the like of various repairing cells, and the repairing cells are the main body of wound repair.

Therefore, we propose a pyramidal skin three-dimensional skin grafting method, which seeks to reduce the contracture of the grafted skin by changing the direction of the tissue connection plane between the grafted skin and the skin fracture layer, and simultaneously increase the dermal carrying capacity of the grafted skin while establishing a multi-plane skin surface, and reduce the contracture of the grafted skin to the maximum extent under the guidance of the three mechanisms. However, there is no special apparatus for manufacturing the conic skin strip, so there is a need to provide a conic skin picker to at least partially solve the problems in the prior art.
