[0002] In order to treat diseases such as urinary incontinence, fecal incontinence, gastroesophageal reflux disease, etc., a medical device is usually implanted in the patient's body, and the medical device includes a strap assembly, which is specifically arranged to form a ring-shaped structure around the surface of the corresponding human organ, and the diameter of the delivery channel of the human organ is adjusted by controlling the contraction or expansion of the ring-shaped structure. In particular, in the case of urinary incontinence or fecal incontinence, the contraction action of the ring-shaped structure formed by the strap assembly essentially forms an artificial sphincter.

[0003] Furthermore, the medical device is provided with an actuator for driving the ring-shaped structure to expand and contract. Before the medical device is placed in the patient's body, the actuator is often separated from the restraining belt assembly. In order to ensure the driving effect between the actuator and the restraining belt assembly, a cap is often provided at the driving end of the restraining belt assembly to protect the driving end.

[0004] However, there is at least one of the following problems in the related technology: the matching method between the cap and the driving end in the related technology is relatively simple, specifically, the cap is sealed to the driving end only by relying on the elastic deformation characteristics of the cap itself, which causes the cap to fall off from the driving end accidentally in dynamic environments such as transportation.
