Closure folder operation principle：
The Ni-based marmem tissue closure folder of titanium, including the closure clip main body that the band by closing is formed；Closure
Band is sequentially connected by the interior segmental arc of staggered at least three outer arc segments and identical quantity head and the tail；The band of closure forms flat
Planar layout, disk like layout or bowl-shape layout；There is hyperelastic titanium Ni-based shape when the band of closure is by higher than memory temperature
Memory alloy material is made, after external force unloading or high again when external force acts on or can changed during less than memory temperature its shape
Refresh memory shape when memory temperature.
The operation principle of the Ni-based marmem anal fistula internal orifice closure folder of titanium is exactly that make use of the Ni-based shape memory of titanium to close
The temperature effect and superlastic sexual function of gold are pulled open at low temperature, and closure reverts to shape memory under high temperature, are increased with tissue
Raw, necrosis physiological Mechanism is combined, and the reasonability of the Ni-based marmem anal fistula internal orifice closure clamping structure design of titanium,
Realize the identical purpose of tissue tissue.
The Bi He Clip made of the shape memory function characteristic of the Ni-based shape memory alloy material of titanium are released to affected area,
Make to press from both sides with temperature or the closure changed in outer masterpiece, it can be played and clinically implement the leading role of operation.
Engaging tissue：
It is semi-closure conjunction state, closed-gap 1-2mm or so that memorial alloy anal fistula internal orifice is closed into folder memory.By closing for closure
Co-clip pulls open rear enclosure on the closure holder of delivery device of the present invention, and cocking, push rod travels forward, and drives steel wire to transport forward
Move, steel wire drives push ring to move downward, and closure is pressed from both sides and pushed at the tissue that needs close.If necessary, tissue is tied up with fine rule
Tie, silk thread passes from through hole, tenses, and pulls tissue into closure folder, then cocking, release closure folder, makes ring-type
The tissue to be closed is clamped at center, continues Self-pressurizing agri, and tissue is tightly pushed down and coincide.The tissue of pressurization is good because of blood circulation
Good, the hyperblastosis of pressurization forms cicatricial tissue and provides regeneration, reaches the purpose of engaging tissue.
Cutting tissue：
It is fully closed condition that memorial alloy anal fistula internal orifice is closed into folder memory, and remaining step is identical with engaging tissue.Add
Tissue ischemia is caused to make necrosis in the ring of pressure, while ring inner tissue one side is downright bad, the hyperblastosis of the outer another side of ring
Make engaging tissue.Due to ring inner tissue ischemic necrosis, otch is formed, slough comes off, Ti-Ni marmem closure folder
Also come off therewith, de- fall behind in the presence of enterocinesia excretes, and makes not stay foreign matter in vivo.
Close the reliability of folder：
Pressed from both sides with the closure of the Ni-based marmem board making of the titanium of different-thickness, its constant pressure characteristic determines simultaneously
Different tissues thickness can be compensated, and place tissue is produced and stablizes lasting pressure, so as to ensure uniform and controllable pressurization
Anastomosis procedures.Make the regeneration of engaging tissue portion within the different time, slough comes off, and ensure that the reliable of engaging tissue
Property.
Closure folder comes off the time：
The operation principle of the Ni-based marmem anal fistula internal orifice closure folder of titanium is exactly that make use of the Ni-based shape memory of titanium to close
The temperature effect function of gold is pulled open at low temperature, and closure reverts to shape memory under high temperature, with hyperblastosis of human body, the life of necrosis
It is external for the exclusion that comes off of closure folder after ten days, ten days that reason mechanism is combined the organization healing time.
The design principle and design structure and clinical manipulation and make that the Ni-based marmem anal fistula internal orifice closure of titanium is pressed from both sides
It is more scientific, easier with peg stapling apparatus all more all than clinic at present, it is a preferable tissue closure binder tool.
