Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an endoscope handle with locking limit and an endoscope. Background Technology

[0002] As a medical diagnostic instrument, the endoscope's insertion tube can be inserted into the body through natural orifices or incisions. Medical personnel adjust the bending motion of the active bending section located at the distal end of the insertion tube by controlling the rotation direction and angle of the rotating component on the endoscope handle, thereby adjusting the posture of the active bending section located at the distal end of the insertion tube.

[0003] Currently, in related technologies, medical personnel need to actively maintain the relative position of the actuating component on the endoscope handle by hand to brake the actuating component and thus maintain the active bending posture of the endoscope. This not only restricts the hand movement of medical personnel but also easily causes hand fatigue. Chinese Invention Patent Publication No. CN116019412B discloses an endoscope handle including a housing, a rotating component, an actuating component, a braking component, and a drive mechanism. The rotating component and the actuating component are rotatably connected to the housing. The braking component is connected between the rotating component and the actuating component. The drive mechanism connects with the braking component and drives the braking component to slide on the actuating component, so that the braking component connects with the housing to brake the rotating component or separates from the housing to release the braking of the rotating component. Thus, the driving mechanism and the braking component achieve braking of the rotating component, replacing the operator's manual maintenance of the active bending posture of the endoscope. The above solution uses the cooperation of the braking component and the drive component to connect the braking component to the housing to achieve the braking effect; however, this braking method has a complex structure and high manufacturing cost.

A wear-resistant pad is arranged in the limiting groove 11, and the friction is further improved.

[0030] Preferably, the knob 3 is fixed on the rotating shaft of the rotating member 2 by a locking screw 32, and is installed and disassembled by the locking screw 32, so that the knob 3 is integrally formed with the extension plate 31, production is more convenient, and the knob 3 is relatively more stable.
