Minimally invasive carpal tunnel release decompression auxiliary device

Technical Field

The utility model relates to a carpal tunnel syndrome surgical instruments field, specificly relate to a wicresoft's carpal tunnel release decompression art auxiliary device.

Background

Carpal tunnel syndrome is a group of symptoms and signs exhibited by the median nerve when the carpal tunnel is compressed, and belongs to the most common one of peripheral nerve entrapment syndromes. The patient presents with prick, numbness, weakness or pain in the radial and radial halves of the fingers, and pain in the arms between the partially conscious hands and elbows. The treatment includes home treatment, physical treatment, drug treatment, surgical treatment and the like. Carpal tunnel incision decompression is used as a standard operation formula for treating carpal tunnel syndrome and is used by a plurality of operators till now. The advantages of the traditional carpal tunnel incision decompression are well known, such as clear lesion exposure, thorough decompression, definite curative effect and the like, but meanwhile, the operation has certain defects, the incision S-shaped passes through the wrist, the postoperative scar is not concealed enough, the appearance is influenced, complications such as columnar pain, bowstring-shaped deformity and the like often occur after the operation, and simultaneously, the operation for daily life can be rubbed to cause discomfort.

Therefore, many scholars research and improve the surgical approach and instruments with the purposes of improving the appearance after the operation and reducing the surgical complications and explore a treatment method of the carpal tunnel syndrome, the surgical design mostly does not directly pass through the wrist, but the skin and the subcutaneous tissue bridge of the wrist are reserved, the damage to the nerve endings of the wrist can be reduced, thereby reducing the postoperative complications, and meanwhile, the position can be far away from the thenar region, and the interference to the grip strength is reduced. The inventor has been engaged in the clinical research of the minimally invasive carpal tunnel release decompression surgery for a long time, and has adopted a single operation and developed a corresponding simple first generation instrument and a second generation surgical instrument combined with an endoscope since 2015, in the operation, an incision is made from the intersection point of the radial side edge extension line of the ring finger and the Kaplan baseline to the near end, about 1.5-2.0 of the incision is made, aponeurosis is cut, tissues around the superficial arch of the palm are separated bluntly by vascular forceps, the self-made instrument is inserted into the near end of the carpal tunnel from the surface of the nerve and the tendon, further, the transverse carpal ligament is cut by a surgical knife, the transverse carpal ligament is ensured to be cut by inserting the instrument to about the transverse carpal striation level, in the cutting process, the problem that how to ensure the nerve and the blood vessel not to be accidentally injured, how to quickly obtain the surgical path and how to quickly insert the surgical knife needs to be considered by the operator. Based on the research and clinical practical experience, the inventor researches and designs the minimally invasive carpal tunnel decompression and loosening auxiliary device, and the device can effectively protect nerves and blood vessels from being accidentally injured in the using process and can effectively assist in cutting transverse carpal ligaments.
