Description

Bipolar electrocoagulation forceps and electrocoagulation equipment

Technical Field

The utility model relates to the field of medical instruments, in particular to an electrocoagulation forceps, especially a bipolar electrocoagulation forceps and an electrocoagulation device.

Background Art

Bipolar electrocoagulation is used in microsurgery to discharge and coagulate microvessels. Its working principle is to connect to the electrocoagulator host through the forceps wire, clamp the bleeding site with the tip of the forceps, and the electrocoagulator releases current to form a loop between the two forceps tips, providing high-frequency electrical energy to the lesion tissue, causing the blood vessels between the two ends of the bipolar forceps to dehydrate, denature and coagulate. Since the current only flows between the two forceps tips, it will not cause burns to other parts, making it very suitable for various microsurgeries. It can still stop bleeding in the presence of saline, blood, and cerebrospinal fluid.

A water dripping electrocoagulation forceps is disclosed in the patent with publication number CN115813537A, comprising:

The tweezers body is a tubular structure, the inner wall of the tweezers body surrounds and forms a first flow channel, and the first flow channel is arranged to penetrate the tweezers body axially;

The tweezer tip is fixedly connected to the tweezer body to form an integrated tweezer blade; the end of the tweezer tip close to the tweezer body is hollowed out to form a second flow channel, and the second flow channel is connected to the first flow channel; the end of the tweezer tip away from the tweezer body is provided with a drip port, which is connected to the second flow channel; in a working state, the drip port is suitable for guiding the physiological saline in the first flow channel and the second flow channel to the wound surface.

Among them, a welding part is arranged at one end of the forceps body away from the forceps tip, and the welding part is suitable for welding and connecting with an electric wire, so that the dripping electrocoagulation forceps is electrically connected to an external electrocoagulation device host through the electric wire.

In addition, a water inlet is provided at one end of the forceps body away from the forceps tip, one end of the water inlet is connected to the first flow channel, and the other end is connected to the dripping pipe, so that the dripping electrocoagulation forceps is connected to the external water storage device through the dripping pipe.

The above-mentioned dripping electrocoagulation forceps have the disadvantage that since the dripping electrocoagulation forceps are connected to an external electrocoagulation device host through an electric wire and connected to an external water storage device through a dripping pipe, if the electric wire or the dripping pipe is damaged, it will inevitably affect the use of the electrocoagulation forceps and the operation.
