Abstract

Localization guidance surgical electrocoagulation scissors comprise a front-end scissor mechanism and a control mechanism which are connected through a carbon fiber tube. The front-end scissor mechanism comprises a pair of scissor bodies, and a middle support with the top hinged to the pair of scissor bodies and the bottom hinged to a bobbin. The control mechanism controls the opening, closing and homodromous swinging of the pair of scissor bodies through steel wire ropes, and the control mechanism controls the swinging of the middle support through a steel wire rope. The middle support is conical, and a wiring groove is formed in the side wall of the middle support. The pair of scissor bodies is connected with an electrode through an electrocoagulation wire to form the single-pole electrocoagulation scissors, the electrocoagulation wire is fixedly connected to the bottom of the bobbin, and the electrocoagulation wire does not move along with the pair of scissor bodies. Wearing of the electrocoagulation wire is slight, the service life is long, and the service life of micro-equipment is prolonged overall.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to monopolar electrocoagulation scissors for minimally invasive surgery. Background technique [0002] Unipolar coagulation means that a metal plate with a large area is in contact with the patient's buttocks as one of the electrodes, which is called the patient electrode or invalid electrode, and the other electrode is connected to the hemostatic device for electrocoagulation. [0003] The difference between bipolar coagulation and monopolar coagulation is that the ineffective electrode in contact with the buttocks is canceled, and the two electrodes are respectively connected to the two blades of a pair of tweezers, and the two blades of the tweezers are insulated. When applied, the current passes only through the tissue between the two tips of the forceps. [0004] The application number is 02216805.2, and the invention patent specification whose authorized announcem...
