Problems solved by technology

At present, the medical surgical suction cutter used in the hospital has defects such as not being able to be sterilized by high temperature and high pressure, the instrument is easy to rust, physiological saline and the resected object enter and exit through the same catheter, and the operation is complicated. Short, the doctor's labor intensity increases, the operation time is prolonged, and the wound is not easy to control. What's more, the patient has a lot of bleeding and strong pain, which increases the fear of surgery and leads to delays in early treatment.

Abstract

The invention relates to a medical operation attracting cutter used for cutting the polyp and the vegetation in the department of otorhinolaryngology. The present medical operation attracting cutter: 1. the reducer and the motor connected thereof are directly fixed on the main body, which is a one-piece structure, the motor and the reducer after being sterilized are easy to rust and erode; 2. the pipe is the same to suck the physiological saline and discharge the sewage conduit, which is easy to arouse the cross infection of germ. The invention includes a main body, a motor module which can be inserted into the main body and a cutter module assembled on the main body, characterized in that, the motor and the reducer are assembled in the motor module, and the reducer is meshed with a telescopic engage switch sleeve. The motor module and the main body in the invention is a fission type structure, which can be detached to avoid the motor and the reducer from being eroded, and prolongs the service life; the pipe to suck the physiological saline and the pipe to discharge the sew is separated, which avoids the germ cross infection, ensures the safety of the patients.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical operation suction cutter used for removing nasal polyps and proliferative bodies in sinusoscopic surgery. Background technique [0002] At present, the special medical device is a medical operation suction cutter when carrying out the nasal polypectomy operation under the sinus endoscope. At present, the medical surgical suction cutter used in the hospital has defects such as not being able to be sterilized by high temperature and high pressure, the instrument is easy to rust, physiological saline and the resected object enter and exit through the same catheter, and the operation is complicated. Short, the doctor's labor intensity is increased, the operation time is prolonged, and the wound is not easy to control. What's more, the patient has a lot of bleeding and strong pain, which increases the fear of surgery and leads to delays in early treatment. Contents of the invention [...
