Abstract

The invention discloses a multifunctional minimally-invasive scalpel for an operation on the tendon sheath. The multifunctional minimally-invasive scalpel comprises a scalpel handle, a straight scalpel body and a two-bent scalpel body, wherein the scalpel body ends of the straight scalpel body and the two-bent scalpel body are connected with the scalpel handle and are perpendicular to each other, the two-bent scalpel body comprises a front scalpel body section, a rear scalpel body section and a scalpel tip section, one end of the front scalpel body section is connected with the scalpel handle, and the other section of the front scalpel body section is connected with one end of the rear scalpel body section. Due to the fact that an included angle b is formed between the scalpel point section and the rear scalpel body section, and an included angle a is formed between the rear scalpel body section and the front scalpel body section, an operator can smoothly and effectively solve pain and numbness symptoms caused by tenosynovitis stenosans, ligament hypertrophy, carpal tunnel syndrome, elbow tunnel syndrome, scapulohumeral periarthritis and the like under direct-vision linear operation, an opening is formed to enter a sheath, and during removal from the sheath, natural release cannot cause medical and traumatic injury to a patient. The combination of the two-bent scalpel body and the straight scalpel body achieves multiple purposes, reduces pollution, facilitates production, storage and transportation, and is low in cost, high in benefits and convenient to disinfect.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a multifunctional tendon sheath scalpel. Background technique [0002] Finger flexor tendon stenosing tenosynovitis, also known as "trigger finger", is mainly caused by the slippage of the flexor tendon at the beginning of the fiber sheath. It is one of the common and frequently occurring tendon diseases in the hand. It is more common in middle-aged women, and the thumb is more frequent. Severe Affect daily life and work. Treatment methods mainly include conservative treatment and surgical treatment. Conservative treatment includes: local immobilization, physical therapy, drugs, closed therapy, etc., but the drugs are mainly non-steroidal anti-inflammatory drugs (NSAIDS), such as aceclofenac tablets, ketoprofen sustained-release capsules, etc., and oral options are also available Cox-2 inhibitor, celecoxib (celecoxib, Celebrex), but these drugs have some side effects, often in...
