An Electric Skin Knife Device Based on Linear Bearings

Abstract

The invention discloses an electric dermatome device based on a linear bearing. The electric dermatome device based on the linear bearing comprises a motor shaft, an eccentric shaft, a linear bearing, a concave slide block, a bracket, a handpiece, a handle, a direct-current motor, a blade, a controller, a battery, a switch and a fine tuning knob, wherein the motor shaft is connected with the eccentric shaft; the front end of the eccentric shaft is directly inserted into the concave slide block in which the linear bearing is arranged; the bracket is arranged at the front end of the handpiece; the handle is connected with the handpiece of the dermatome; the direct-current motor and the battery are arranged inside the handle; the blade is arranged in a handpiece groove; the controller is connected with the handle; the switch is arranged on the upper surface of the handle; and the fine tuning knob is arranged on one side of the handpiece. Due to the arrangement of the linear bearing, starting friction resistance and the kinematic friction resistance are extremely small due to flow contact; and a linear moving bearing has the characteristics of high interchangeability, convenience in installing and using, time saving, novel mechanical structure, small size and light weight.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an electric skin removal device based on a linear bearing. Background technique [0002] Launched in 2009, our company has developed several skin flap blades. As a medical consumable, this product can be used together with several foreign brands of electric dermatologists. By the end of 2012, the skin flap blades produced by our company have sold nearly 2.5 A total of 3,000 flap blades were used in Xijing Hospital and Tangdu Hospital in Xi'an, which were well received by burn hospitals and surgeons, filling the gap in the domestic market. [0003] However, some foreign electric dermatologists have many shortcomings in actual users. For example, they can only use alternating current, which cannot meet the requirements of different departments and different doctors, and even sudden power outages in the operating room; the motor participates in high-temperature and high-pres...
