The invention relates to a medical surgical clamp matched with an endoscope, in particular to a visible surgical clamp with an endoscope sheath used for taking the intrauterine device out from the uterus. The existing visible surgical clamp is used in the birth control surgery, for example in the surgery to take the intrauterine device out from the uterus with the endoscope. Due to the easy bleeding of the endometrium tissue, the lens of the endoscope is easily contaminated to dim the surgery view, and the device is inserted in and taken out repeatedly for flashing, therefore the surgery time is prolonged and the operation is complicated. After the improvement, the groove formed after the side by side arrangement of the endoscope sheath and the drive rod is also fixed with two flush pipes 15 and 17, wherein the open of one flush pipe faces the open of the endoscope sheath 10, and the open of the other flush pipe faces a clamp head 6. A surgical cannula is provided, and the water nozzle on the surgical cannula is communicated with a negative pressure source to absorb and remove the water of flushing. The improved surgical clamp provides clear surgery view, has compact integral structure and convenient operation, and can shorten the surgery time.

A high-frequency electrosurgical station applicable to surgeries and worthy of popularization is a special high-power high frequency generator. The high-frequency electrosurgical station generates high frequency current of specific frequency, waveform and load power curves; the high frequency current directly acts on the surface of biological tissues and centrally heats the tissues to volatilize tissue elements, and accordingly physical effects such as cutting and hemostasis are achieved. Through high-frequency power output by a main unit of the high-frequency electrosurgical station and jaw pressure of vessel forceps, collagen and fibrous protein in human tissues fuse and degenerate, walls of blood vessels fuse into a transparent tape, and permanent luminal closure is achieved. In open surgery or endoscopic surgery, a vessel closure cutting system can be given to full play for any vein, artery or tissue-bundle, smaller than 7mm in diameter, and closing or cutting is safer, faster or more convenient. The above advantages are hardly found in ultracision harmonic scalpels and bipolar coagulation. The high-frequency electrosurgical station has the functions of unipolar incision, unipolar coagulation, bipolar coagulation, bipolar incision, large vessel close-cutting and the like and is a necessity for operating rooms in future.
