The calculus gripping device for the urological department adopts the U-shaped gripping head, does not easily hurt the urethra when a calculus gripping device is inserted into the urethra from the urethral meatus and is used for calculus gripping of the urological department.

Description

A kind of urology department is used the calculus grabber

Technical field

This utility model belongs to technical field of medical instruments, is the calculus grabber that a kind of urology department is used concretely.

Background technology

The calculus grabber that existing urology department is used, because grasping end (grab bucket) adopts the opening type structure, and grab bucket is processed by many steel wires; When grasping calculus of urethra; After the calculus grabber inserted from urethral orifice, grasping end caused damage to urethra easily, is prone to cause urinary tract infection.

Summary of the invention

The purpose of this utility model provides a kind of when grasping calculus of urethra, is difficult for causing the urology department of damage to use the calculus grabber to urethra.

A kind of urology department is used the calculus grabber, and described urology department comprises that with the calculus grabber U-shaped grasps termination, seal wire, sleeve pipe, spring, pushes away handle, sliding sleeve, and the two ends that U-shaped grasps the termination are fixedly connected with the front end face of seal wire; The medial surface that U-shaped grasps the termination is provided with sawtooth, and casing pipe sleeve is contained on the seal wire, and telescopic inwall is provided with a plurality of semi-cylindrical hills that U-shaped grasps the termination that are used to clamp; Telescopic rear end face is fixedly connected with an end of spring; Sliding sleeve is sleeved on the seal wire, and sliding sleeve and sleeve pipe and seal wire are slidingly matched, and spring is between sliding sleeve and sleeve pipe; Push away handle and be fixedly connected with the rear end face of seal wire, U-shaped grasps the termination and grasps the termination for the U-shaped of being processed by spring steel.

This utility model adopts U-shaped to grasp the termination because U-shaped grasps the outer surface smoother of termination, when the calculus grabber when urethral orifice inserts, U-shaped grasps the termination and is difficult for urethra is caused damage, has reduced the chance of urinary tract infection.The medial surface that U-shaped grasps the termination is provided with sawtooth, when grasping calculus, has increased frictional force, extracting calculus that can be firm.

During use, utilize to push away handle and promote seal wire, the calculus grabber of this utility model is inserted into from urethral orifice, when U-shaped grasping end headgear is on calculus; Firmly promote sliding sleeve forward, the spring compression promotes the sleeve pipe reach, and telescopic front end sleeve is contained in U-shaped and grasps on the termination; And through semi-cylindrical hill clamping U-shaped extracting termination, again through the tight calculus of U-shaped grasping end head-clamp, afterwards; Retracting spring, and pulled backwards seal wire take out calculus.
