Novel skin graft rolling device

Abstract

The invention discloses a novel skin graft rolling device. The device comprises a base, a skin graft rolling device body and a placing table, a portal frame is installed on the base, a lead screw motor is installed above the portal frame, and the lead screw motor is in transmission connection with a lead screw; the skin graft rolling device body comprises a movable bottom plate, the movable bottom plate is movably connected to the outer surface of the lead screw, guide rod frames and a rack frame are installed on the movable bottom plate, a movable frame is movably connected to the outer surfaces of the guide rod frames through sleeve rods, a first driving motor and a skin graft rolling machine are installed on the movable frame, and the driving motor is meshed with a rack on the rack frame through a first gear; and the driving end of the skin graft rolling machine penetrates through a strip-shaped groove and is connected with a cutting blade. The defects in the prior art are overcome, and a cutting blade is driven by the driving motor to move and cut in the Y-axis direction; and the rotating angle of the faulted skin graft on the horizontal plane is controlled through a second driving motor, and the whole placing plate is driven to axially move on the horizontal plane by controlling a third driving motor, so that the cutting work of the skin graft of different specifications or different sizes is realized.

Description

technical field [0001] The invention relates to the technical field of peeling machines, in particular to a novel peeling device. Background technique [0002] Skin grafting refers to a piece of skin that is completely free from the body without subcutaneous fat. It is removed from one part of the body and transplanted to another to restore circulation and survive. It is often applied to patients with moderate or severe skin burns. According to different skin grafting methods, free skin grafts can be divided into stamp-shaped skin grafts, microparticle skin grafts, mesh skin grafts, and medium-thickness and full-thickness or mesh grafts with subdermal blood vessels. [0003] At present, the mainstream skin rolling machine is manually operated. By turning the handle, the rotating shaft with the blade is rolled to pass through the tray with the faulty skin between the rotating shafts to achieve a mesh skin, or to repair the wound after two superimposed 90-degree rolling. The ...

Problems solved by technology

[0003] At present, the mainstream skin rolling machine is manually operated. By turning the handle, the rotating shaft with the blade is rolled to pass through the tray with the faulty skin between the rotating shafts to achieve a mesh skin, or to repair the wound after two superimposed 90-degree rolling. The required skin sheet has a simple process but is not fine and accurate enough, and the operation steps are cumbersome
