Description
Technical field
The utility model relates to medical surgical instruments, more specifically to one kind for Minimally Invasive Surgery under digestive endoscopy
Vessel forceps.
Background technique
Malignant tumor of digestive tract is gastral common disease, frequently-occurring disease, has seriously threatened the life and health of the mankind, and with
Society gradually step into ageing stage, malignant tumor of digestive tract discovery rate also increases therewith, swollen for some alimentary canals early stage
Tumor can be treated by endoscopic minimally-invasive and carry out tumor resection, it will be able to reach radical result.
With the continuous development of Clinics under digestive endoscopy and scope, endoscopy increasingly becomes disease of digestive tract
Routine inspection means, so that the discovery of alimentary canal infantile tumour is also more and more, Endoscopic Treatment also increases therewith, causes and controls
It treats relevant complication accordingly also to increase, endanger among these maximum no more than Alimentary Tract Perforation.In Alimentary Tract Perforation can be divided into
Mirror diagnosis and treatment perforation complication and active digestive system tube wall stoma, as perforated when endoscopy, gastrointestinal polyps excision,
The perforation of the generations such as EMR, ESD and stomach wall full-thickness resection (EFTR) and through natural cavity endoscopic surgery (NOTES) notch
It is surgical operation repairing Deng, the primary treatment regimen of former Alimentary Tract Perforation, with the progress of endoscopic instruments and technology, a part
Alimentary Tract Perforation can be sutured under scope.
Currently used Alimentary Tract Perforation closure techniques mainly have conventional hemostatic clamp closure, big hemostatic clamp closure, nylon ring
Device hemostatic clamp purse string suture method, OTSC (over-the-scope-clip system), metal closure by clip are covered, in addition, eating
The perforation at the relatively narrow position such as pipe, duodenum also can be used provisional precoated metal stent in the treatment, but above-mentioned treatment there is
The disadvantages of technical difficulty is high, cumbersome, the time is long, reliability is not high, some also only exist in animal experiment stage.
In all Alimentary Tract Perforation suturing skills, surgical stapling technology is most basic, most reliable and other
After the completion of technology is difficult to, the suture means of final choice.Surgical stapling technology can accomplish alimentary canal tube wall holostrome apposition suture,
An important factor for this is organization healing and prevents gastrovascular cavity postoperative leakage, above-mentioned suturing skill is difficult to reach.In by digestion
When mirror carries out suture operation, since the pincers road space of digestive endoscopy is very limited, the diameter that gastroscope clamps road is about 2.8mm, colonoscopy
The diameter for clamping road is about 3.2mm, and clamps length in itself in 1.2~1.4mm or so, can in space long and narrow in this way
