Problems solved by technology

Tissue dissociation and blood vessel dissociation mainly use tissue forceps for blunt separation. When tissue forceps bypass certain important structures such as blood vessels and bronchi, they often encounter soft tissue resistance. Due to the limitations of laparoscopic surgery, only relatively large forces can be used. Forced breakthrough, often causing vascular or bronchial injury

Embodiment Construction

[0016] combine figure 1 It can be seen that the present invention is a suction head of a suction device for a laparoscopy with cutting function and suction function, comprising a circular tube body 1 and a suction port 2 at the front end; the circular tube body 1 has a circular cutter 3. The front end of the cutter 3 has a blade-like or tooth-like structure, and the rear end is connected to the inner wall of the circular tube body 1; the front end of the cutter 3 faces the suction port 2, and is 22-5mm away from the suction port.

[0017] The distance between the front end of the cutter 3 and the suction port 2 is preferably 3mm.

[0018] Wherein, the angle between the side wall of the cutter 3 and the tube wall of the circular tube body 1 is 5-30°.

[0019] The front end of the cutter 3 is a blade-shaped structure, and the angle between the side wall and the wall of the circular tube body 1 is preferably 5-15°.

[0020] Wherein, the distance between the front end of the cut...

Abstract

The invention provides a suction head of a suction apparatus with a cutting function for an endoscope. The suction head comprises a circular tube body and a suction port at the front end, wherein an annular cutter is arranged in the circular tube body; the front end of the cutter is provided with a cutting-edge-shaped or tooth-shaped structure, and the back end of the cutter is connected to the inner wall of the circular tube body; and the front end of the cutter faces the suction port, and is 2-5 millimeters away from the suction port. According to the suction head provided by the invention, soft tissues which prevent tissue forceps from passing through can be cut through the cutter in the suction apparatus, and the tissue forceps can break through successfully and easily, so that operation becomes easy; and meanwhile, the structure and size of each position are combined organically in the suction head under the consideration of the problems of efficiency and safety in a surgery process, so that good cutting and suction effects are ensured simultaneously, and the surgery safety is ensured.

Description

technical field [0001] The invention relates to a suction head of a suction device with a cutting function for a cavity mirror. Background technique [0002] The aspirator is used to suck the contents of bleeding, exudate, pus, and chest viscera during the operation, so as to make the operation clear and reduce the chance of contamination. Suction devices are inseparable from the removal of accumulated blood or fluid during surgery, and the manipulation of the broken ends of ruptured blood vessels. [0003] Aspirators are also often used in laparoscopic surgery to cooperate with tissue dissociation and blood vessel dissociation, mainly to absorb blood oozing during tissue dissection. Tissue dissociation and blood vessel dissociation mainly use tissue forceps for blunt separation. When tissue forceps bypass certain important structures such as blood vessels and bronchi, they often encounter soft tissue resistance. Due to the limitations of laparoscopic surgery, only relative...
