Problems solved by technology

[0004] The technical problem to be solved in the present invention is: currently the existing feeding device for digestive endoscope adopts friction wheel to realize the feeding function of digestive endoscope, but the rotation of friction wheel will cause friction force at the same time, which is not conducive to the force detection of the feeding device. Moreover, it is easy to get stuck in an accidental situation, which is not conducive to the safety of patients; thereby providing a new type of digestive endoscope feeding device

Abstract

The invention discloses a novel digestive-endoscope feeding apparatus and belongs to the field of medicine instruments, aiming to solve problems that an existing digestive-endoscope feeding apparatusadopts a friction wheel to realize the feeding function, the rotation of the friction wheel causes friction force which is not conducive to the detection of force, and easy getting stuck by accident is not conductive to the safety of patients. The novel digestive-endoscope feeding apparatus comprises a fixed housing, a swing mechanism, two clamping mechanisms, two feeding mechanisms, two upper sliding plates and four first sliders; the swing mechanism includes a rotary frame and a drive assembly, the rotary frame is arranged in the fixed housing, the drive assembly is arranged outside the fixed housing, and the rotary frame performs rotary motion through the drive assembly; each of lower ends of two ends of each upper sliding plate is provided with a first slider fixedly, the upper slidingplates are respectively and sliably connected onto the upper end face of the rotary frame side by side through the first sliders at two ends of the upper sliding plate, and each upper sliding plate is provided with one clamping mechanism and one feeding mechanism. The novel digestive-endoscope feeding apparatus is used for feeding and outputting of the digestive endoscopy.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a digestive endoscope feeding device for digestive endoscopy. Background technique [0002] The field of medical devices is an intersecting field between the medical field and the robotics field. It is a development trend to apply the advantages of the robotics field to the medical field. In the traditional digestive endoscopy, the doctor needs to hold the digestive endoscope to operate and swing. The doctor is prone to fatigue and trembling under the long-term working state, resulting in blurred and distorted images. With the development of science and technology, robotic medical assistance technology can be very good to solve these problems. The robot-assisted technology can provide a stable spatial posture, and the doctor can adjust the feeding degree and posture of the digestive endoscope by adjusting the switches and buttons, which can effectively reduce the doctor's fatigue....
