Colonoscope handle operator for assisting doctor in colonoscopy

Abstract

The invention discloses a colonoscope handle operator for assisting a doctor in colonoscopy. A poking wheel driving mechanism, a handle fixing mechanism, a biopsy forceps closing mechanism and a biopsy forceps conveying mechanism are arranged on a U-shaped supporting plate; the handle fixing mechanism is used for fixing the colonoscope handle on the handle fixing mechanism; and a colonoscope thumbwheel is tightly attached to the inner side of a thumb wheel shell. A doctor drives the motor to control the rotating direction and angle of a poking wheel; the motor and the thumb wheel shell are driven by a synchronous belt; the accuracy of the rotating angle of the thumb wheel is ensured; the biopsy forceps conveying mechanism can ensure that biopsy forceps wires are conveyed into a biopsy channel; the biopsy forceps closing mechanism can control the opening and closing of the biopsy forceps tip. The operator can replace a traditional mode of manual impeller operation of a doctor to solvea problem that muscles of fingers and shoulders of the doctor are injured by long-time impeller stirring; meanwhile, a traditional mode of assisting the doctor in operating conveying and opening and closing of biopsy forceps by an assistant is replaced, and the purpose that the doctor independently completes colon examination and polyp extirpating work is achieved.

Description

technical field [0001] The invention belongs to the field of endoscopic surgery medical robots, in particular to an operation mode for doctors to perform colon examination. Background technique [0002] Global cancer statistics show the morbidity and mortality of 36 cancers in 185 countries around the world. The data show that there are about 18.1 million new cases and 9.6 million cancer deaths per year, of which the incidence and mortality of colorectal cancer account for 10.2% and 9.2% respectively , ranking third and second in cancer rankings. However, 80% of colorectal cancers are transformed from benign colorectal polyps. If colorectal cancer can be detected and treated at an early stage, the survival rate will be significantly improved. Therefore, the key to preventing colorectal cancer is to find and remove polyps as soon as possible. [0003] Colonoscopy is used to examine, diagnose, and treat inflammatory ulcers, polyps, tumors, etc. in the colorectal wall mucosa ...

AI Technical Summary

Problems solved by technology

[0004] Because colonoscopy requires interventional surgery through the natural orifice of the human body, the internal space of the intestinal cavity is narrow, the curvature is complex, the intestinal wall is full of folds, and has certain stretch characteristics. Compared with other operations, the environment is complex and the operation is difficult. And the characteristics of high risk, so higher requirements are put forward for the doctor of colonoscopy. The doctor needs to control the rotation of the large and small dial repeatedly with one hand for a long time, and cooperate with the other hand to advance and rotate the scope to observe the intestinal cavity lesions , frequent operations will cause discomfort to the doctor, and distraction will make the operation difficult to achieve the best results. At the same time, the long-term colon examination operation will cause great damage to the doctor's fingers and shoulders
