Description

Medical suction separating forceps for endoscopic surgery

Technical Field

The utility model belongs to the field of medical equipment, in particular to a medical suction separating forceps for endoscopic surgery.

Background

Laparoscopic surgery is a minimally invasive procedure that is technically more complex and often requires more time than open surgery. One reason for this is that each surgical port in the abdominal cavity can only accommodate one surgical instrument at a time. When bleeding inevitably occurs in the laparoscopic surgery, the surgeon must temporarily withdraw the ultrasonic blade and replace it with a suction apparatus for blood suction, and the existing surgical separation forceps do not have a suction function. Such a one-handed replacement is complicated and time-consuming. If the replacement time is too long, a small amount of bleeding during the operation may infiltrate into the surrounding tissues, so that the surrounding tissues are discolored red, and the bleeding is difficult to identify, thereby influencing the judgment of doctors and delaying the operation process. Therefore, in view of the obstacles of function optimization of the endoscopic surgical instruments, there is still a great need to develop an attractable separating forceps with a suction function on the endoscopic surgical separating forceps.

Detailed Description

The embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1-3, a medical suction separating forceps for endoscopic surgery comprises operating arms hinged together through a pin shaft 3, wherein the operating arms are divided into a front forceps arm 1 and a rear forceps arm 2, the front forceps arm 1 and the rear forceps arm 2 are respectively provided with an operating finger ring, the front forceps arm 1 is connected with an endoscopic hollow rod 10 and is connected and fixed with a detachable sealing cap 9 into a whole through a knob 8, and the knob can rotate 360 degrees; the rear end of the hollow rod 10 of the endoscope is provided with a negative pressure suction connecting port and a negative pressure suction regulating valve 7, a negative pressure suction pipe 6 is inserted on the negative pressure suction connecting port, the opening and closing of the suction pipe are controlled by the negative pressure suction regulating valve 7, and the negative pressure suction pipe 6 is communicated with a negative pressure device 5; the rear end of the rod core 15 is provided with a clamping groove 16, the rod core 15 is inserted into the hollow rod of the endoscope, and the rod core 15 is clamped and fixed through the lock catch 4 on the rear tong arm 2; the hollow cavity of the cavity mirror hollow rod 10 is communicated with the negative pressure suction tube 6, the cavity is normally in a closed state, and when the cavity mirror hollow rod is required to be used, the negative pressure suction adjusting valve 7 is pressed down, so that a negative pressure passage is formed between the negative pressure suction tube 6 and the cavity of the cavity mirror hollow rod 10.
