Robotic system for assisting doctor in operating colonoscope

Abstract

The invention discloses a robot system for assisting a doctor in operating a colonoscope. The robot system comprises a handle driving mechanism, a colonoscope feeding mechanism, a handle controller pose adjusting mechanism and a pose adjusting driven arm. The handle driving mechanism can replace a traditional mode that a doctor manually pokes an impeller; the rotation angle of the colonoscope tipis adjusted; the colonoscope feeding mechanism can replace a doctor to convey a colonoscope into the intestinal tract of a patient; the handle controller pose adjusting mechanism can adjust the angleand the position of the handle operator to realize convenient colonoscope delivery; the pose adjusting driven arm can adjust the colonoscope to the anus of a patient to realize convenient conveying ofthe colonoscope. The device can replace a traditional mode of manual impeller operation of doctors, a problem that the fingers and the shoulders of the doctors are injured by long-time impeller stirring is solved; meanwhile, the traditional mode of assisting the doctors in operating conveying and opening and closing of biopsy forceps by assistants is replaced, and the purpose that the doctors independently complete colon examination and polyp extirpating work is achieved.

Description

technical field [0001] The invention belongs to the field of endoscopic surgery medical robots, and in particular relates to an operation mode of a colonoscope during a doctor's 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...

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
