Antiskid sleeve and colonoscope handle

Abstract

The invention relates to the technical field of medical instruments, and in particular relates to an anti-skid sleeve and a colonoscope handle; the anti-skid sleeve comprises an inner sleeve body andan outer sleeve body; the inner surface of the inner sleeve body is used for sleeving an angle knob of the colonoscope handle; and the outer surface of the inner sleeve body and the inner surface of the outer sleeve body are arranged in a matched and sleeving mode. The inner surface of the inner sleeve body is designed in match with the shape of the angle knob, so that the inner sleeve body does not rotate and slide relatively after sleeving the angle knob; the inner surface of the outer sleeve body is matched with the outer surface of the inner sleeve body in shape design, so that it is guaranteed that the outer sleeve body is prevented from moving and slipping after sleeving the inner sleeve body; and meanwhile the connection tightness between the inner sleeve body and the angle knob ofthe colonoscope handle is enhanced. The antiskid sleeve is larger than the angle knob, equivalently, the size and the structure of the angle knob of the colonoscope handle are changed, so that the distance between fingers of a doctor and the angle knob in an operation process is reduced, the problem that a thumb is difficult to make contact with a small operation wheel during operation of the doctor is solved, and the effect of simplifying operation is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an anti-slip cover and a colonoscope handle. Background technique [0002] At present, colonoscopy generally adopts the single-person colonoscope insertion method. During operation, the doctor's left hand operates the colonoscope handle, and controls the up, down, left, and right rotation of the apex where the lens is located by turning the up and down angle knobs and left and right angle knobs, and the right hand operates the colon The mirror body is used to advance or withdraw the insertion tube part. The left hand of the doctor operating the handle needs to grasp and lift the handle while using the thumb and ring finger to jointly control the up and down / left and right angle knobs. Due to the large weight and volume of the handle, the angle knobs in the up, down and left and right directions protrude outwards, and the function control buttons on the upper end of the ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the distance between the angle knob of the handle of the existing colonoscope and the doctor's finger is far away, and it is difficult to turn it during the operation, and it is inconvenient to rotate the angle knob
