Abstract

The invention belongs to the technical field of medical instruments, and discloses a roll shaft skin taking knife for burn patients. The roll shaft skin taking knife comprises a fixing frame and an eccentric fixing stent connected to the inside of the fixing frame; a knife holder is mounted in the eccentric fixing stent, and a pressing roller is fixedly connected to one side, close to the knife holder, in the eccentric fixing stent through a stent; a blade is connected to the side, close to the pressing roller, of the knife holder; a driving device is installed on the side, close to the eccentric fixing stent, in the fixing frame; and the driving device comprises two grooves and a movable shaft, wherein the two grooves are located in the two sides of the inner wall of the fixing frame respectively. The fixing block, the driving wheel, a lead screw, a threaded sleeve and other structures are arranged in the driving device in a matched mode, so that the eccentric fixing stent moves stably and reliably, the knife holder is stressed evenly, and the pushing force degree is controlled conveniently; and therefore, the blade can stably move to cut, the safety coefficient is increased, theoperation is simple and labor-saving, and the skin taking efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a roller dermatologist for burn patients. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body. Autologous skin or allogeneic skin needs to be cut and transplanted to the defective skin, and the roller dermatome is a commonly used instrument in burn surgery. It is widely used. [0003] There are some problems in the use of the existing roller dermatome used for burn patients. For example, in the process of pushing the dermatome to cut the skin, it is difficult to control the pushing force, not only is it more difficult to push, but the direction of the thrust is also difficult. Offset is easy to occur, resulting in unstable movement of the dermatome and error-prone. When the dermatome cuts ...
