Abstract

The invention discloses an operation supporting sleeve and a puncture guiding needle capable of being used by combination, which are characterized in that the main body of a sleeve (1) is a round tube provided with an opening (2) on the tube wall, the head of the puncture guiding needle (4) is spiny, and when used by combination, the sleeve (1) is sleeved on the tail of the puncture guiding needle (4). The operation supporting sleeve and the puncture guiding needle are convenient to use and have high security. The operation supporting sleeve and the puncture guiding needle are mainly used for cutting off ligamenta or cutting part of the ligamenta in operative treatment of nerve compression wounds on a wrist or other parts and incising deep tissues in a minimally invasive surgery.

Description

technical field [0001] The invention relates to a medical device, in particular to a combination-used surgical support sleeve and puncture guide needle. Background technique [0002] At present, endoscopic minimally invasive surgery is used to treat nerve entrapment injuries in wrists, ankles and other parts. It only needs to cut off the corresponding ligaments. The operation is simple and the curative effect is good, which is welcomed by surgeons and patients. However, due to the lack of special medical equipment for this operation, the operation is not very convenient and fast during the operation, and it is easy to damage the peripheral nerves and tissues of the surgical site, resulting in low safety. In addition, the surgical instruments used are not disposable and may easily lead to cross-infection . Contents of the invention [0003] The purpose of the present invention is to provide a combined operation support sleeve and puncture guide needle which is convenient, ...
