Medical disposable electric motor saw

Abstract

The invention discloses a medical disposable electric motor saw, which comprises a handle and an enclosure main body, wherein a non-removable battery and a circuit control panel which is connected with the battery are arranged in the handle; a press part of the handle is provided with a speed adjusting switch which is connected with the circuit control panel; a hollow motor which is provided with a driving shaft is arranged in the enclosure main body; the battery is a rechargeable lithium battery; a charging socket is formed in the bottom or the lateral part of the handle; a sterile sealing bag is arranged on the outer sides of the handle and the enclosure main body. After the structure is adopted, and the hollow motor is used, the medical disposable electric motor saw is stable in transmission and good in braking performance, the weight of the medical disposable electric motor saw is about a half of that of an electric motor saw with a common motor, the structure is simple, the fault rate is low, the medical disposable electric motor saw is easy to carry and use, the manufacturing cost is low, the battery cannot be detached, so the loosening or dropping phenomenon cannot occur, and the completion quality of a surgery is effectively ensured. The sterile sealing bag is used, the wait for high-temperature high-pressure sterilization is not needed, and the medical disposable electric motor saw can be used any time. The precious operation time is saved for an emergency operation patient.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a medical disposable electric saw drill. Background technique [0002] In surgical bone surgery, medical electric saw drills are the most commonly used surgical equipment. The medical electric saw drill is a power tool for trauma surgery. Now the high temperature and high pressure medical electric saw drill has gradually replaced the industrial saw drill that can only be fumigated and sterilized. It can withstand high temperature below 135° and high pressure of 1.6 MPa. It can kill some bacteria and viruses that cannot be killed by fumigation, and shorten the disinfection time. It only needs to be treated at 135 ° high temperature and high pressure for 20 minutes, which has won precious time for emergency surgery patients. [0003] However, the above-mentioned medical electric saw drills that can be reused many times still have the following deficiencies: [0004] 1. The motor part is us...

AI Technical Summary

Problems solved by technology

[0004] 1. The motor part is usually installed in the main body. Due to the inability to disassemble the motor and long-term use, the sealing quality of the electric saw drill is reduced. Generally, the motor is corroded due to the residual water vapor after disinfection, and the functions of the battery, speed control switch and drive circuit board Lost and unable to work, which affects the performance of the electric saw drill, and even affects the quality of the operation

[0005] 2. Before use, it needs about 20 minutes of high temperature and high pressure disinfection trea
