Description
Technical field
This utility model relates to a kind of medical clip carrier, particularly a kind of medical clip carrier of being convenient to the locking and unlocking.
Background technology
In recent years Endoscope hemostasis folder because of its traumatic little, anthemorrhagic speed soon, the feature such as low, the few intercurrent disease of hemorrhage incidence rate, determined curative effect again, become critical patient acute gastrointestinal bleeding non-operative treatment the most effectively, have the method for clinical value most.Under scope, metal clip hemostasis is one of hemostasis means of comparatively extensive use, and appropriate case is carried out to skilled metal clip operation, can effectively stop blooding and prevent more hemorrhage, and minimizing untoward reaction, improves safety and the cure rate of digestive tract hemorrhage therapeutic endoscopy greatly.The hemostatic mechanism of metal hemostatic clamp is with surgery vascular ligation or sew up identical, for a kind of physical mechanical method, the mechanical force producing while utilizing hemostatic clamp closed, by its surrounding tissue and the ligation in the lump of hemorrhage blood vessel, thereby closed hemorrhage blood vessel, with blocking blood flow, reach hemostasis object, be applicable to the hemostatic treatment of nonvariceal active hemorrhage and visible vessels stump pathological changes.
While there is little perforation in endoscopic surgery, applied metal folder is organized clamp by cut, by cut sealing, prevents that alimentary canal content from leaking to abdominal cavity.For local organization, the poor or postoperative Suspected Area of APC presss from both sides and closes, can pre-blowout resistant generation.
Metal clip is visible under X-ray examination, if endoscopic surgery cannot complete resection focus, while needing further surgical operation, at lesions position, places 1～2 piece of metal clip, can be peritoneoscope or abdominal inspection provides indicative function.Metal current hemostatic clamp external product is in the great majority.The TriClip Endoscopic Clipping Device of COOK for example, opening diameter is 12mm, it is better to eminence lesion, as the residual base of a fruit after polypectomy, and application process, without rotation, can reduce the usage quantity of metal clip, but there are some researches show, because this design contacts with 3 of human bodies, this metal clip haemostatic effect is slightly poor.Bostonian
clip, opening and closing is no more than five times repeatedly, metal clip opening is 11mm, can make repeated attempts closure or open to adjust position of operator, but the partial-length that this metal clip is kept somewhere is in vivo about 15mm, after operation, keeping somewhere part can close the offside tissue friction at place with folder, cause ulcer, especially in esophagus or intestinal, more easily occurs.The patent 2005143767 of Olympus is mentioned a kind of rotatable metal clip, can select the metal clip of respective diameters according to the size of pathological changes diameter.Its clip is the joggle piece that has locking design between curved intersection type structure, clip and clamping element and prevent from again opening after clamp.Complex structure, has higher requirement to the proficiency level of user.About the spacing design of conveyer device; Boston clip is to utilize the casing protection clip of outside not open in entering scope process; avoid Dui Qian road to damage; enter behind human body relevant position; the positioner at handle place is shifted out; then by sleeve pipe to operator's one side shifting, convenience is inadequate in actual applications.
