Planer cutter power control mechanism

Abstract

The invention discloses a planer cutter power control mechanism. The mechanism comprises a shell, a control system suite, a negative pressure connector, a negative pressure switch kit, a motor, a cable suite and a cutter assembly, wherein the control system suite, the negative pressure connector and the negative pressure switch kit are installed on the shell; the motor is arranged in the shell, one end of the motor is connected with the cutter assembly, and the other end of the motor is connected with the cable suite; the control system suite comprises a hall sensor and a PCB control panel, the hall sensor is arranged at one end of the PCB control panel, and a wire connected with the motor is arranged at the other end of the PCB control panel; the cutter assembly is provided with a permanent magnet. The permanent magnet transmits signals to the hall sensor, the signals are transmitted to a host through the connected PCB control panel, the host determines the model of a cutter accordingto the signals, and then the rotation speed corresponding to the cutter is obtained through adjustment. The mechanical structure is optimized, the type of the cutter is intelligently detected throughthe hall sensor, and then the rotating speed of the cutter is automatically adjusted, so that time is saved; the PCB control panel and the hall sensor are used as main controllers, so that the service life is effectively prolonged.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a planer power control mechanism. Background technique [0002] In the operation of excision of internal or external tissues such as ear, nose, throat, neck bone and joints, it is necessary to use a planer and other scalpels to remove diseased tissue or excess tissue; while operations performed in small spaces such as ear, nose and throat and inside the body are different from other surgical procedures. Due to the limitations of space and vision during the operation, inaccurate or incomplete resection often occurs, the efficiency of the operation is low, the wound is large and the bleeding is large, and the postoperative recovery period is long, which increases the pain of the patient. Increased treatment costs. Therefore, there is a need for an instrument suitable for surgery in a small space and in the body, which can completely and accurately remove diseased tissue and redund...

AI Technical Summary

Problems solved by technology

[0003] The existing medical planer power control mechanism manually detects different types of knives and then adjusts the corresponding tool speed, which has poor flexibility and takes a long time to operate; the mechanical switch used is complex in structure and short in service life.
