Problems solved by technology

[0005] The above technology has the following problems: the whole is made of medical resin or soft material, which has poor rigidity, and cannot directly reach the affected area when used, and the bending angle is small, so the scope of application is narrow
However, the existing control device requires two-handed operation and fixation, which affects the efficiency and quality of medical examination.
At the same time, the existing control mechanism has complex structure and high cost

Abstract

The invention provides a bending controlling mechanism of a medical endoscope. The bending controlling mechanism comprises a bending portion, a bending driving unit and a hand wheel adjusting device. The bending portion is provided with an outer cover, a bending assembly and a fixed barrel, the bending assembly is sleeved with the outer cover, and the fixed barrel is fixedly connected to the front end of the bending assembly. The bending driving unit comprises at least four control cables and control balls, the positions, corresponding to the control cables, of the fixed barrel is provided with connecting grooves in the circumferential direction, and the control balls at the end portions of the control cables are arranged in the connecting grooves respectively. The hand wheel adjusting device is connected with the control cables in a driving mode, and the hand wheel adjusting device is further provided with two sets of limiting and self-locking mechanisms. The bending assembly variable in range is adopted in the bending controlling mechanism, free bending is achieved through a controlling mechanism arranged in the bending controlling mechanism, resetting is achieved through the bending assembly variable in range, and the bending controlling mechanism has bending and resetting effects, reduces high cost in the whole operation process, achieves disposable use really, and is high in control accuracy and good in control effect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bending control mechanism of a medical endoscope. Background technique [0002] An endoscope is a commonly used medical device, which consists of an insertion part, a bending part, a front end, a control part and a host, wherein the insertion part, the bending part and the front end are collectively called an insertion tube. It enters the human body through the natural orifice of the human body, or a small incision made by surgery; when in use, the insertion tube of the endoscope is introduced into the pre-examined organ, and the changes in the relevant parts can be directly observed. [0003] Endoscope is a kind of delicate medical equipment. Most of the domestic medical endoscope market is occupied by foreign products. The price ranges from tens of thousands to hundreds of thousands. Complicated and costly disinfection and maintenance are required after each use. ...
