Electric skin grafting net machine

Abstract

The invention discloses an electric skin-grafting net making machine comprising a machine frame, a knife roll and an auxiliary roll, the knife roll and the auxiliary roll are installed on the machine frame in a rotating mode and are arranged in parallel to form a roll cutting pair for net making, and the knife roll or / and the auxiliary roll is / are driven by an electric assembly to rotate. By the adoption of driving of the motor, power is output in a deceleration mode through a reducer or a gear motor is directly adopted according to needs, a stable and even power source is provided due to rotation continuity of the motor, the sense of jerking is eliminated, evenness of a skin graft is ensured after a net is made, distortion of a skin expanding ratio caused by unstable rotation of the knife roll is avoided in the making process, and the working efficiency is high.

Description

technical field [0001] The invention relates to a medical device, in particular to a skin-grafting net-making machine used in surgical operations. Background technique [0002] Skin grafting mesh machine is a medical device used to expand skin grafts in surgical operations such as burn treatment. The enlarged area; conducive to the healing of the skin after skin grafting. [0003] Due to the small and simple structure of the existing net-making machines, manual methods are generally used to provide power for the net-making machines; although the manual structure is simple, manual frustration will occur. For relatively high-level operations, the instability of manual driving will lead to problems such as unevenness of the skin after the net is made, and even have an adverse effect on the control of the expansion ratio, and the controllability is not good. [0004] Therefore, it is necessary to improve the existing skin-grafting net-making machine, provide a stable and unifo...

[0003] Due to the small and simple structure of the existing net-making machines, manual methods are generally used to provide power for the net-making machines; although the manual structure is simple, manual frustration will occur. For relatively high-level operations, the instability of manual drive will lead to problems such as unevenness of the skin after the mesh is made, and even have an adverse effect on the control of the expansion ratio, and the controllability is not good.
