Description

Technical Field

[0001] The utility model relates to the technical field of electrocoagulation snares, in particular to a disposable multifunctional electrocoagulation snare. Background Art

[0002] A high-frequency electrosurgery unit is a medical surgical instrument that can incise and electrocoagulate tissue, causing the surface of severed capillaries to coagulate and stop bleeding. Due to its superior cutting and hemostatic properties, high-frequency electrosurgeries are widely used in surgery. Furthermore, electric snares are routinely used for endoscopic removal of polyps or tumors in the respiratory and digestive tracts. These devices utilize a high-frequency current to generate intense heat and cauterize tissue that comes into contact with the snare, allowing for complete and rapid removal of polyps and complete hemostasis.

[0003] Existing disposable multifunctional electrocoagulation snares have external wiring during use, which is inconvenient and not fixed. For example, a Chinese patent discloses a "disposable multifunctional electrocoagulation snare for tracheobronchoscopy," with application number "CN202223395974.3." This device combines an electrocoagulation probe and an electrocoagulation snare, which operate on the same principle. The electrocoagulation probe can be used alone to open blocked airways or dilate narrowed airways. To address the problem of residual marginal tissue that is difficult to treat after electrocoagulation surgery, the electrocoagulation probe can be used for additional electrocoagulation without removing or replacing the kit. However, the wiring is not fixed during use. Utility Model Content
