Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a closed release device that can be used throughout the body. Background Art

[0002] Medical devices mainly refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items used on the human body. Computer software is the equipment required for them. Medical devices are mainly obtained through physical means rather than pharmacological or metabolic means. However, these methods only play an auxiliary role to facilitate medical staff to treat patients.

[0003] The transverse carpal ligament releaser is a type of medical device. For existing transverse carpal ligament shearing surgeries, most of them are performed using traditional surgical operations or traditional transverse carpal ligament releasers, which involve making a large incision on the patient's wrist and then finding the transverse wrist for cutting. These two methods result in a large incision on the patient's wrist, which requires a lot of time for suturing surgery and a long postoperative recovery time, which can easily cause infection at the incision site and threaten the patient's life safety.

[0004] Traditional systemic closed release devices use a sleeve to guide the cutter to the cutting position for cutting, but the blade of the cutter is mostly fixed. During the movement along the sleeve, there is a problem of cutting other body tissues, causing unnecessary wounds. Utility Model Content
