Embodiment 1

[0032] The base 10, the rotating shaft 11 fixed on the base, and an annular handle 12 assembled on the base 10 and rotatable around the rotating shaft 11, the inner circumference of the handle 12 has tooth lines 121, so The base 10 is provided with an elastic member 13 abutting against the tooth pattern 121 , and when the handle 12 rotates, the elastic member 13 abuts against the crest 1211 and the tooth root 1212 of the tooth pattern 121 alternately.

[0033] There is a guide rail 101 arranged radially along the inner circumference of the handle 12 on the base 10, and the elastic member 13 includes a slider 131 which can move along the guide rail 101 and whose head abuts against the tooth groove 121, and a The tail of the slider 131 is an elastic part that pushes the slider 131 along the direction of the guide rail 101 . The elastic part can be, for example, a shrapnel 132 , and the shrapnel 132 is accommodated and fixed in the space at the tail of the slider 131 . When the f...

Embodiment 2

[0042] The handle part 1, and the operating part 2 provided on the handle part 1, the operating part 2 has a rotating shaft 21 fixed on the holding part 1, and the rotating shaft 21 is provided from the inside to the outside and can respectively surround The rotating shaft 21 independently rotates the first shaft sleeve 211, and the second shaft sleeve 212 partially surrounds the first shaft sleeve 211. The operating part 2 also has The first handle 22 and the second handle 23 that are fixedly connected, the second handle 23 has a handle rotation control structure, specifically: there is a fixed ring around the rotating shaft 21 between the second handle 23 and the handle 1 On the base 24 on the handle part 1, the inner circumference of the second handle 23 has tooth lines 231, and the base 24 is provided with an elastic member 25 abutting against the tooth lines 231. When the two handles 23 are rotated, the elastic member 25 abuts against the crest 2311 and the root 2312 of t...

Abstract

The invention provides a handle rotation control structure and an endoscope device using the handle rotation control structure. The control structure comprises a base and an annular handle which is arranged on the base and can rotate relative to the base, wherein insections are formed on the inner circumference of the handle; an elastic component which is resisted against the insections is arranged on the base; and when the handle rotates relative to the base, the elastic component is resisted against tooth crests and tooth roots of the insections alternately, so that a rotation angle of the handle relative to the base can be precisely controlled according to a designed angle, and the handfeel of the operation is optimized.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to a handle rotation control structure and an endoscope device. Background technique [0002] Endoscope is a medical instrument used to insert into the body through the natural orifice of the living body so as to check the internal organ lesions of the body. It usually has a hand-held operation part and an insertion part. The insertion part is a flexible pipe. The front end of the insertion part includes a light beam and a CCD The array, or the ultrasonic transducer assembly, collects optical images or ultrasonic signal data, sends them back to an externally connected image processor for processing, and displays them to the user on the display. The front end of the insertion part controls its bending orientation and positioning in the body by holding the operation part. The existing hand-held operation part of the endoscope usually has a columnar handle part and an operation part vertical...
