Bipolar electric coagulation forceps capable of being cut under endoscope

Abstract

The invention relates to the field of medical instruments, and particularly relates to bipolar electric coagulation forceps capable of being cut under an endoscope. The bipolar electric coagulation forceps comprise a fixed handle, a movable handle, an outer tube, a forceps head and an electric connector, wherein the outer tube is rotationally arranged on the fixed handle, the far end of the outer tube penetrates through the fixed handle to be provided with the forceps head, a forceps head push piece is arranged in the outer tube, one end of the forceps head push piece is in transmission connection with the forceps head, the other end of the forceps head push piece extends out of the outer tube to be located in the fixed handle, the movable handle is rotationally connected with the fixed handle, and the movable handle is in transmission connection with the forceps head push piece; the forceps head and the forceps head push piece are electrically connected to the electric connector, the electric connector is located outside the fixed handle, and the electric connector is used for being connected to a high-frequency electrotome main machine; and a smoke inlet is formed in one end of the outer tube, and the other end of the outer tube communicates with a smoke suction tube through a rotary sealing assembly. The bipolar electric coagulation forceps are reasonable in structural arrangement, good in electric coagulation effect, safe to use, beneficial to smoke removal and capable of ensuring clear operation view.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a bipolar electric coagulation forceps that can be cut under an endoscope. Background technique [0002] In laparoscopic surgery, energy instruments are used to separate, grasp, and coagulate blood vessel ends. Now the ultrasonic knife is commonly used, but the ultrasonic knife has obvious disadvantages: ①The sealing effect on blood vessel ends is not high-frequency The equipment based on the principle of bipolar coagulation is stable, which may cause secondary bleeding or oozing of the patient after surgery; ② only blood vessels with a diameter of less than 1mm can be sealed, resulting in the use of vascular clips which inevitably increases the surgical cost of the patient. ③The thermal penetration injury to the nerve tissue within a radius of 3mm from the tissue contact site is unavoidable, which is likely to cause complications. High-frequency bipolar coagulation forceps can ...

[0002] In laparoscopic surgery, energy instruments are used to separate, grasp, and coagulate blood vessel ends. Now the ultrasonic knife is commonly used, but the ultrasonic knife has obvious disadvantages: ①The sealing effect on blood vessel ends is not high-frequency The device based on the principle of bipolar coagulation is stable, which may cause secondary bleeding or oozing of the patient after surgery; ②It can only seal blood vessels with a diameter of less than 1mm, resulting in the use of vascular clips which inevitably increases the patient’s surgical costs

③The thermal penetration injury to the nerve tissue within a radius of 3mm of the tissue contact site is unavoidable, which is likely to cause complications

High-frequency bipolar coagulation forceps can provide more stable electrocoagulation hemostasis effect and ensure absolute safety of peripheral nerve tissue in laparoscopic surgery, and reduce or even avoid the use of vascular clips to reduce the cost burden of patients, such as Hangzhou Kangji Medical The disposable bipolar coagulation forceps KJ-SJ0105 of Instrument Co., Ltd., but the current domestic bipolar coagulation forceps for laparoscopic surgery does not have the function of electric cutting tissue, and can only stop bleeding with coagulation forceps, so it cannot effectively replace ultrasound The position of the knife in laparoscopic surgery, this product design is to overcome this weakness, so that the bipolar coagulation forceps can effectively cut tissue, thereby replacing the ultrasonic knife, and bring better surgical results to patients undergoing laparoscopic surgery and lower cost
