Problems solved by technology

Due to operation errors caused by the long-term operation fatigue of the operator, it is likely that when the endoscope intervenes in the human body, a large extrusion force will occur between the endoscope lens and the human tissue. When the extrusion force exceeds a certain threshold, It will lead to soft tissue damage, which may lead to medical accidents such as perforation of human tissue
There are roughly two types of existing endoscopes, one is to use an angle slider to limit the position, and the other is to use a traction device with a worm gear mechanism. These two types of endoscopes have complex structures and require high manufacturing precision. Relevance and interaction between parts are highly required, and the degree of dependence on other devices of the endoscope is high. The operation requires the coordination and adjustment of the endoscope as a whole, and the use efficiency is low.

Abstract

The invention discloses an endoscope with an angle adjusting function. The endoscope comprises an endoscope handle, an angle adjusting mechanism, a hard sheath, a soft sheath and a steel wire rope winding wheel with an output shaft. The inner end portion of the hard sheath is connected with the endoscope handle, the soft sheath is located in the hard sheath, and the soft sheath stretches out of the end portion of the hard sheath. The angle adjusting mechanism comprises an angle adjusting handle and a two-stage transmission gearbox. First-stage transmission in the gearbox is gear transmission, and second-stage transmission in the gearbox is worm gear transmission. An input shaft, a middle shaft and an output shaft are arranged in the gearbox. The steel wire rope winding wheel is fixed on the output shaft. A driving gear and a driven gear of the first-stage transmission are arranged on the input shaft and the middle shaft respectively. A worm is arranged on the middle shaft, a worm gear is arranged on the output shaft, and the angle adjusting handle is sleeved and installed on the input shaft. The endoscope is good in reliability, simple in structure and convenient to assemble. The pressure can be adjusted according to different requirements.

Description

technical field [0001] The invention relates to a medical device, in particular to an endoscope with an angle adjustment function. Background technique [0002] The endoscope enters the human body through the natural orifice of the human body, or through a small incision made through surgery. An endoscope is a commonly used medical device. When in use, the endoscope is introduced into the pre-examined organ, and the changes in the relevant parts can be directly observed. The diagnosis and treatment effect of the endoscope is highly dependent on the skill and experience of the physician, and there are also high requirements for the stability and sensitivity of the endoscope device. It is necessary to avoid repeated angle adjustment and positioning in the patient's body. High safety and high efficiency are urgent needs to meet the requirements of clinical diagnosis and treatment. Due to operation errors caused by the long-term operation fatigue of the operator, it is likely...
