Bipolar electric coagulation forceps

Abstract

The invention discloses a bipolar electric coagulation forceps, which comprise a bivalve forceps body and an electrode holder, the bivalve forceps body comprises a holding part and a forceps rod part,the forceps rod part comprises a forceps tip at the front end and a forceps body close to the holding part, when pressure is applied to the holding part or the holding part is loosened, the forceps tip is loosened or clamped, and the forceps tip is rotatably connected with the forceps body. The forceps tips can rotate around a connecting shaft between the forceps tips and the forceps body. A modethat the forceps heads are opened to work during kneading is adopted, so that the difficulty that the traditional electric coagulation forceps cannot smoothly open the head ends (forceps tips) and cannot work due to the fact that a minimally invasive incision is too small is overcome, especially an endoscope single-hole incision; the two forceps bodies and the two corresponding forceps tips are rotatably connected to form two rotatable joints, the rotating angles of the two joints can be adjusted at will according to actual requirements under the action of external force with certain strength, the two joints can be repeatedly adjusted and fixed at the set bending angle, and it can be guaranteed that in the operation process, by repeatedly adjusting the rotating angles of the two joints, bleeding target points of almost all parts can be reached safely and smoothly, and bleeding can be stopped smoothly. The inner side faces and the outer side faces of the tips of the oval forceps are covered with polytetrafluoroethylene coatings, only the exposed side edges are reserved to guarantee electric conduction, scab can be efficiently prevented from being generated, complex water flushing is not needed in the using process, and serious interference of water dripping on the visual field is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a special holding type bendable bipolar electrocoagulation forceps for minimally invasive surgery. Background technique [0002] Existing bipolar electrocoagulation tweezers are composed of a double-lobe tweezers body (including a grip part and a tweezers shaft) and an electrode seat. The tail ends of the double-lobe tweezers body are connected to the electrode seats respectively, and a high-frequency input plug is provided on the electrode seat. , the outer surface of the double-lobe tweezers is provided with an insulating layer, and a water channel is provided along the direction of the tweezers inside any petal of the double-lobe tweezers. The water inlet at the rear end is drawn from the wall of the flap tweezers and is sealed and connected to the water delivery guide. Bipolar coagulation tweezers are embedded in the body of the tweezers with a water channel formed...

AI Technical Summary

Problems solved by technology

[0003] The double-lobe tweezers (including the grip part and the tweezer shaft) of the current bipolar coagulation forceps are integrally formed, and the angles of the tweezer shaft and the tweezer tips are not adjustable. Part of the bleeding position in the mirror cannot be reached and cannot work, and there is difficulty in working because of the inability to open the tip of the forceps after reaching the deep position. In addition, continuous water injection at the tip of the forceps will seriously interfere with fine surgical operations
