Description

Endoscope operating rope winding system

technical field

The utility model relates to the technical field of endoscopes, in particular to an endoscope operating rope winding system.

Background technique

In common endoscopes, the winding system drives the operating rope to generate traction force on one side of the end of the endoscope lens, so as to control the bending direction of the bending part of the endoscope. The endoscope winding system generally includes a winding seat, and a winding wheel located in the winding seat and rotatable relative to the winding seat. groove, the operating rope is wound in the groove of the winding wheel, driven by the winding wheel, the two ends of the operating rope are pulled and loosened to the end of the endoscopic lens. One side generates traction, which drives the end of the endoscopic lens to bend to that side. The winding seat has a disk-shaped bottom surface and a circular arc-shaped side wall on the periphery, and the side wall and the groove form a storage space for the operating rope.

However, when the winding wheel is rotated, one end of the operating rope is in a tensioned state, and the other end is in a relaxed state, and the end in the relaxed state is easily in contact with the side wall and scratches occur, resulting in damage to the operating rope , and increase the frictional force between the operation rope and the side wall, so that the winding operation is not smooth.

Contents of the invention

In order to solve the above problems, the utility model provides an endoscope operating rope winding system, which is used to prevent the operating rope in a relaxed state from contacting and rubbing against the side wall of the winding seat.

The technical scheme that the utility model adopts is:

An endoscope operating rope winding system, comprising: a disc-shaped winding seat with a bottom surface and an arc-shaped side wall, and an outlet connected to the outside of the winding seat extends from both ends of the arc-shaped side wall the winding wheel coaxially arranged with the winding seat, the winding wheel can rotate relative to the winding seat, the outer periphery of the winding wheel is provided with an outwardly opening annular groove, and the operating rope Located in the annular groove, the two ends of the operating rope extend out of the winding seat from the outlet; between the outer peripheral edge of the winding wheel and the arc-shaped side wall, a plurality of rolling body.

Further, the endoscope operating rope winding system of the present invention may also include a cover plate covering above the rolling body to seal the rolling body between the outer periphery of the winding wheel and the arc. between the side walls.

Further, the rolling body is a cylindrical rolling body.

Further, the two ends of the cylindrical rolling body are provided with axially outwardly protruding cylindrical protrusions coaxial with the rolling body, and the bottom surface of the winding seat and the cover plate are respectively provided with A plurality of receiving parts for receiving the protrusions.

The beneficial effect of the utility model is that one end of the endoscope operating rope in a relaxed state does not contact or rub against the side wall of the winding seat, thereby protecting the operating rope and making the winding operation smoother.

Detailed ways

The technical solutions in the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Referring to Fig. 1 and Fig. 2, the endoscope operating rope winding system of the present invention comprises a disc-shaped winding seat 1, has a bottom surface 11 and an arc-shaped side wall 12, and the two ends of the arc-shaped side wall 12 extend A lead-out port 13 that communicates with the outside of the winding seat is provided; the winding wheel 2 coaxially arranged with the winding seat 1, the winding wheel 2 can rotate relative to the winding seat 1, and the winding wheel 2 can rotate relative to the winding seat 1. The outer periphery of the wheel 2 is provided with an outwardly opening annular groove 21, the operating rope 3 is located in the annular groove 21, and the two ends of the operating rope 3 extend out of the winding seat 1 through the outlet 13; A plurality of rolling elements 4 are arranged between the outer peripheral edge of the winding wheel 2 and the arc-shaped side wall 12 .

The utility model is provided with a plurality of rolling elements 4 between the outer peripheral edge of the winding wheel 2 and the arc side wall 12, so that the operating rope 3 will not contact the arc side wall 12 in a relaxed state, thereby To avoid scratching, the operating rope 3 is protected. There is rolling friction between the rolling body 4 and the loosened operating rope 3, and the frictional force is very small and negligible, so that the winding operation is smoother.

Referring to Fig. 3 and Fig. 4, preferably, the endoscope operating rope winding system of the present utility model may also include a cover plate 5 covering above the rolling body 4, and sealing the rolling body 4 in the Between the outer peripheral edge of the winding wheel 2 and the arc-shaped side wall 12, the rolling elements can be better positioned.
