When it is necessary to urinate, a second force may be applied to push the locking body 123 to move it from the first position to the second position (that is, move toward the first clamping body 104). At this time, the first The two elastic components 118 are compressed and the ejecting piece 121 of the locking body 123 pushes the locking piece 120 to the release end 119a of the locking groove 119, so that the locked state of the locking component 103 is released, thereby allowing the second clamp The holding body 106 is moved by the first elastic force of the first elastic component 117 in the second direction D2 to move to the urination position from the self-controlled urine position, so that the first urethral clamp 105 and the second urethral clamp 107 Move away from each other, releasing the urethra for urination.

When the urination is completed, the second force can be released, so that the locking body 123 is returned from the second position to the first position by the second elastic force of the second elastic component 118 to release the ejector 121 from the lock. The force of the stopper 120 enables the lockup member 120 to be automatically switched to the locked state during subsequent operations. Therefore, the implantable urine control structure 1 provided by the first embodiment of the present application can provide better urine control effect and has the advantage of less implantation trauma.
