Thermocoagulation grasping clamp for preventing tumor disseminating metastasis

Abstract

The invention discloses a thermocoagulation grasping clamp for preventing tumor disseminating metastasis. The thermocoagulation grasping clamp is characterized in that a thermocoagulation grasping clamp head claw 1, a thermocoagulation grasping clamp head claw 2, a burnt injury prevention insulation protection sleeve, an insulation pipe, a rotating wheel, an electrode connecting wire, a clamp headopening and closing regulating handle, an electrode generator, a pedaling switch and a human body contact plate are installed. When the thermocoagulation grasping clamp head claw 1 and the thermocoagulation grasping clamp head claw 2 are engaged with the tumor tissues, a pedal switch is conducted with an electrode generator; a loop is formed between the pedal switch and the human body contact plate; the thermocoagulation grasping clamp head claw 1 and the thermocoagulation grasping clamp head claw 2 are embedded into the tumor tissue positions to generate heat energy, so that the peripheral tumor tissues in contact with the thermocoagulation grasping clamp head claw 1 and the thermocoagulation grasping clamp head claw 2 are burnt and coagulated to lose the biological growth activity.

Description

technical field [0001] The invention relates to a surgical instrument for laparoscopic surgery. Background technique [0002] Traditional surgical operations are traumatic. In recent years, laparoscopic surgery has been widely used, with less trauma and faster recovery. Taking laparoscopic surgery as an example, it is an operation carried out through several "keyhole" tiny wounds on the abdominal wall. When resecting or removing large tumors in laparoscopic surgery, it is routinely necessary to use grasping forceps to occlude the tumor and pull it out. Because the sharp teeth of the grasping forceps will inevitably cause tissue damage, especially during the operation, multiple and multi-position clamps are required to occlude and pull the tumor, just like "teeth" biting the tissue, the resulting tumor debris tissue or Cells can be attached to the grasping forceps, and can also adhere to the tumor wound, so they can flow into the pelvic and abdominal cavity along with the bl...

Taking laparoscopic surgery as an example, it is an operation carried out through several "keyhole" tiny wounds on the abdominal wall. When resecting or removing large tumors in laparoscopic surgery, it is routinely necessary to use grasping forceps to occlude the tumor and pull it out. Because the sharp teeth of the grasping forceps will inevitably cause tissue damage, especially during the operation, multiple and multi-position clamps are required to occlude and pull the tumor, just like "teeth" biting the tissue, the resulting tumor debris tissue or Cells can be attached to the grasping forceps, and can also adhere to the tumor wound, so they can flow into the pelvic and abdominal cavity along with the bleeding of the tumor injury site and the tumor debris or cell diffusion taken away by washing, and can also follow the entry and exit of the grasping forceps, Or changes in the location of the tumor lead to tumor tissue cells scattered in the abdominal cavity, even a small amount of tumor debris, or tumor cells have growth activity, so it becomes an important cause of tumor recurrence, seriously endangering the lives of patients, and seriously illegal tumor surgery The principle of tumor-free operation should be followed

However, at present, solid tumors are removed under laparoscopy. Without the assistance of grasping forceps, the operation is extremely difficult, which is a last resort.
