Lymph gland biopsy forceps suitable for thoracoscopic surgery and operation method of lymph gland biopsy forceps

Abstract

The invention provides a pair of lymph gland biopsy forceps suitable for the thoracoscopic surgery. The pair of forceps includes a forceps body, the front portion of the forceps body bends forward and downward and is connected with a forceps head, the rear portion of the forceps body is provided with an operating handle used for controlling the forceps body to open and close, the forceps head is provided with a forceps head suction hole and a forceps head side hole, the tail end of the forceps body is provided with a negative pressure suction port, and the negative pressure suction port is communicated with the forceps head suction hole through a cavity in the forceps body. The invention further provides an operation method of the lymph gland biopsy forceps suitable for the thoracoscopic surgery, and the pair of forceps is connected with a conventional intraoperative negative pressure suction device through the negative pressure suction port; the operating handle controls forceps head to clamp and drag lymph gland tissue, water and blood in the lymph gland tissue are discharged through the forceps head side hole, and osmotic blood and frog are sucked away through the forceps head suction hole. The lymph gland biopsy is combined with the suction device into a whole, can be used for clamping and dragging the lymph gland tissue, also can absorb the surrounding osmotic blood and the frog, and makes vision for the surgery clear, and the interference between devices is avoided.

Description

technical field [0001] The invention relates to a lymph node biopsy forceps capable of negative pressure suction suitable for thoracoscopic surgery, especially single-port thoracoscopic surgery, and a working method thereof, belonging to the technical field of surgical instruments. Background technique [0002] Lymph node biopsy forceps is an indispensable tool for lymph node dissection during thoracoscopic surgery. It can directly clamp lymph node tissue and be used for traction of lymph tissue. [0003] In the process of surgical cleaning, due to the rich blood supply of lymph nodes, bleeding from small blood vessels or tissue oozing (in addition to the smoke generated during the cutting process of surgical electric knife and ultrasonic knife) often affects the surgical field of vision and increases the difficulty of surgery. Cooperate with the endoscopic suction device to remove blood and smoke to expose the field of view. Thoracoscopic minimally invasive surgery has a s...

AI Technical Summary

Problems solved by technology

Thoracoscopic minimally invasive surgery has a small incision, especially single-hole surgery usually only has a 3-4cm incision, the number of instruments passing through the incision is limited, and the more instruments, the more mutual interference (lymph node biopsy forceps and aspirator). Not only will it affect the operation, but also prolong the operation time
