Gastrointestinal endoscope surgery needle holding clamp having electrocoagulation function

Abstract

The invention discloses a gastrointestinal endoscope surgery needle holding clamp having an electrocoagulation function. The needle holding clamp comprises a clamp head, a clamp body, a control handleand an electrocoagulation mechanism, wherein a rear end of the lamp head is connected with one end of the clamp body, and the other end of the clamp body is connected with a front end of the controlhandle; via the clamp body, the control handle is used for controlling the clamp head to clamp and release a suture needle and suture lines; the electrocoagulation mechanism is connected with the control handle; the clamp head comprises a pair of clamp arms, a driving mechanism, a clamp head main body and a fixed rotary mechanism; the clamp body comprises an inner core, a spring tube arranged on the inner core in a sleeving manner, and an insulation layer arranged on the spring tube in a sleeving manner; the control handle comprises a handle main body, a slide ring assembly and a locking assembly; the electrocoagulation mechanism comprises a high frequency electric knife and an electrode plate. The needle holding clamp disclosed in the invention is a special-purpose clamp for a gastrointestinal endoscope surgery, and a front end of the needle holding clamp can rotate freely and can open and close freely; the needle holding clamp can help with clamping and locking the suture needle, thetissue and the suture lines; polyps can be electrically removed via fulgerizing operation, and electric coagulation hemostasis can be realized through the needle holding clamp.

Description

technical field [0001] The invention relates to a medical operation instrument, in particular to a needle-holding forceps with electrocoagulation function for digestive endoscopic operation. Background technique [0002] Malignant tumors of the digestive tract are common and frequently-occurring diseases of the digestive tract, which have seriously threatened human life and health. As the society gradually enters the aging stage, the detection rate of malignant tumors of the digestive tract also increases. The tumor can be resected by endoscopic minimally invasive treatment, and a radical effect can be achieved. [0003] With the continuous development of digestive endoscopy and endoscopic diagnosis and treatment technology, endoscopic examination has increasingly become a routine examination method for gastrointestinal diseases, making more and more early tumors of the gastrointestinal tract discovered, and endoscopic treatment also follows The increase will lead to a corr...

AI Technical Summary

Problems solved by technology

Surgical suturing techniques can achieve full-thickness alimentary canal wall suturing, which is an important factor for tissue healing and preventing postoperative leakage of the digestive tract, which is difficult to achieve with the above-mentioned suturing techniques.

When suturing with the help of a digestive endoscope, due to the limited space of the clamp channel of the digestive endoscope, the diameter of the clamp channel of the gastroscope is about 2.8 mm, the diameter of the clamp channel of the colonoscope is about 3.2 mm, and the length of the clamp channel itself is 1.2 mm. ~1.4mm, in such a long and narrow space, the surgical instruments that can be placed are very limited, and the current conventional suturing surgical instruments can no longer meet these requirements, and it is necessary to produce a special instrument for minimally invasive surgery under digestive endoscopy
