The utility model marmem closure folder and the multiple closure clamp device of stack, single closure folder 9 includes titaniumThe band being closed made of nickel shape memory alloy material, band are first by staggered two multiple tooth section 1 and two wave sections 2Tail is connected in sequence.
When carrying out memory processing, it is desirable that: when not reaching memory temperature, two multiple tooth section 1 and two smooth wave sections 2 are located atOn one circumference, when meeting or exceeding memory temperature, two multiple tooth section 1 is parallel to each other to draw close and completes closed action.
To reach best surgical effect, when not reaching memory temperature, two multiple tooth section 1 and two smooth wave sections 2 are located at oneOn a circumference, circular diameter is 8mm~15mm；It being parallel to each other and draws close for two multiple tooth section 1 when reaching memory temperature, spacing is 0~3mm is preferred with 0.1mm~3mm.
Pointed tooth type closure folder or cognate type closure folder may be selected in the different characteristic of identical tissue as needed.
For single closure folder 9 when not reaching memory temperature, two multiple tooth section 1 and two smooth wave sections 2 are located at a circumferenceOn, same closure folder 9 can be stacked gradually placement at this time, achieve the purpose that repeatedly to discharge.
Multiple closure folders 9 are sequentially stacked on a hollow cylindrical release head 3, and there are rope groove 6, rope groove 6 in 3 two sides of release headThe traction rope 4 of knot 5 is accomplished fluently in middle placement in advance, and knot 5 is stuck between two closures folder 9 that heap is folded, by pulling traction rope 4 canClosure folder 9 is successively released.
The memory temperature of Ti-Ni marmem is generally 33 ± 3 DEG C.
The utility model is performed the operation for digestive endoscope.When operation, closure folder 9 is clipped in the mucous membrane or muscle for needing to be closedTissue, deformation occurs under body temperature effect, and multiple tooth section 1 and pointed tooth occlusion thereon of closure folder 9 are jointly closed needsTissue carries out Self-pressurizing agri, and wound tissue is made to achieve the purpose that healing.
The utility model is used for hemorrhoids operation.When operation, closure folder 9 is clipped in the interior hemorrhoidal tissue root for needing to cut offPortion, deformation occurs under body temperature effect, multiple tooth section 1 and pointed tooth occlusion thereon of closure folder 9, the tissue being closed jointly to needsSelf-pressurizing agri is carried out, while pressurization, the organization healing of the good side of blood circulation, other end tissue ischemia necrosis, finallyClosure folder 9 falls off, and has achieved the purpose that hurtless measure and has not stayed foreign matter in vivo.
Occlusion refers to that interior segmental arc 11 and corresponding outer arc segments 12 are coincide.
Trough structure refers to that 2 band of wave section is provided with the warp architecture of similar wave, can be automatic under certain conditionThe length of wave section 2 is adjusted, to accordingly have adjusted the size of closure folder 9 when not reaching memory temperature.
