The utility model discloses when the design:

the tissue biopsy forceps with the electrocoagulation function for the laparoscope has the advantages that: at present, clinically, both patients and surgeons pursue minimally invasive surgery, that is, when performing surgery, a puncture cannula is performed on the abdominal wall of a patient to establish an external connection channel with the abdominal cavity of the patient, the puncture cannula is placed into the puncture cannula by using a special laparoscopic surgical instrument to perform operation in the abdominal cavity, finally, after the surgery is finished, only a tiny operation scar caused by the puncture cannula is left on the abdominal wall of the patient, the operation scar is tiny, and the pain of the patient is light, the surgery mode is commonly called as 'punching surgery', and is gradually accepted by surgeons and patients, however, when performing laparoscopic minimally invasive surgery, some surgeries are often performed, local tissue biopsy of an operation area is required, samples are selected to perform benign and malignant judgment, for example, when performing gastric perforation repair surgery under a laparoscope, partial tissues need to be selected at a gastric perforation point to perform histological case examination, judging whether malignant perforation is possible, and carrying out different operation treatment schemes according to benign and malignant results, wherein no special laparoscopic biopsy tissue instrument exists clinically at present. An electric knife or an ultrasonic knife is often used for excising partial tissue biopsy at a tissue needing biopsy, because the electric knife or the ultrasonic knife works on the principle of electrically excising or thermally excising the tissue, the excised biopsy tissue is burnt sometimes when the tissue is excised, and the biopsy result is influenced. Another scheme is to use scissors to cut off a part of the tissue to be examined for tissue biopsy, but when laparoscopic scissors are used for cutting off the tissue, bleeding often occurs at the material-taking part in the tissue cutting-off process, rapid hemostasis cannot be realized, the biopsy tissue is soaked in blood and is not dissolved in the clamped biopsy tissue, or excessive bleeding of the patient occurs, and postoperative disease recovery of the patient is affected. Above-mentioned shortcoming of solution that this apparatus can be fine, adopt the utility model discloses when carrying out tissue biopsy under the peritoneoscope, at first will lead the conductor wire on electrical pillar 11 and the operating room electricity congeals the machine and link to each other, establish electrically conductive route, then, grip this apparatus, put into the patient abdominal cavity through the puncture sleeve pipe that the belly was established, can be according to the needs of drawing materials, put into tissue clamp 1 with the tissue that needs draw materials, through the moving handle 14 of this apparatus of pullback, under the transmission of connecting rod 15, movable jaw 17 is closed with fixed jaw 16, because tissue clamp 1 is the sharp recess clamp mouth that can cut the tissue, cause tissue clamp 1 to press from both sides completely, cut the tissue, and will draw materials the tissue and leave in the recess, and then convenient clamp gets the tissue of biopsy. After removing the biopsy tissue by clamping, if the tissue wound surface is clamped, when the bleeding occurs, the movable cap 8 can be pushed forward, the electrocoagulation rod 3 is moved out of the insulating sleeve 4, a foot-controlled conductive switch is arranged in the electrocoagulation machine in an operating room (most of electrocoagulation machines in clinical manufacturers are electrically conductive by controlling the foot-controlled switch), a conductive path is established, the electrocoagulation head 2 is contacted with the bleeding point, and the rapid electrocoagulation hemostasis operation is carried out. Through clinical practice, the instrument can obviously reduce the operation time after being used, and effectively improve the operation safety.
