Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to a visual bipolar electrocoagulation forceps with flushing and suction channels. Background Art

[0002] Although the trauma is small during clinical surgery under laparoscopy, it is inevitable that blood vessels will be cut during the operation, resulting in local bleeding. The traditional method of blood clotting is not very applicable in laparoscopic surgery, so the method of electrocoagulation hemostasis is widely used in clinical practice.

[0003] Electrocoagulation has been used for surgical hemostasis for a long time. The current used for surgery is high-frequency current. Even if the voltage is as high as several thousand volts, high-frequency current can pass through the human body safely without causing nerve or muscle reactions. The thermal effect of high-frequency current is used to dehydrate and shrink the blood vessel wall, coagulate the blood in the blood vessel, and fuse the blood vessel and the blood clot into one, thus achieving effective hemostasis.

[0004] In order to better assist the work, we have designed a flushing channel, which can control the flushing tube to spray water through external devices to achieve the cleaning function, and then use the thumb to press and block the suction control air port to achieve the suction function of the suction tube. The electrocoagulation forceps are inclined to improve the convenience of clamping and increase the visual range. At the same time, it ensures the high efficiency of suction, and effectively solves the current problems of being unable to see and clamp. For this reason, we have proposed a visual flushing and suction bipolar electrocoagulation forceps. Summary of the invention
