Specific embodiment

Referring to Fig. 1 to Figure 46, the Ni-based marmem tissue closure folder of titanium, including closure clip main body, close clip main body It is the band of the closure that the Ni-based shape memory alloy material of titanium is made, band is by staggered at least three outer arc segments and identical Quantity interior segmental arc head and the tail be connected in sequence plane layout, disk like layout or bowl-shape layout；The disk like is laid out or bowl-shape cloth The circular cone angular region of the band of the closure of office is 120-180 °, most preferably 160 °.Have when closure band is by higher than memory temperature The hyperelastic Ni-based shape memory alloy material of titanium is processed as the memory proterties for clinically needing.Acted on when external force or less than memory Its shape can be changed during temperature, refresh memory shape when being higher than after external force unloading or again memory temperature.Outer arc segments it is optimal Quantity is 3 or 4, during specific demand, it would however also be possible to employ 5,6 or 8.

Band is the Ni-based shape memory alloy material of titanium, is that, with super-elasticity, can change under external force effect under its memory temperature Become its shape, external force recovers its shape memory after disappearing.

To reach optimal surgical effect, shape memory is set under the conditions of memory temperature, where the top of all interior segmental arcs Diameter of a circle is 1-4mm, and diameter of a circle where the top of all outer arc segments is 10-20mm；Under the conditions of less than memory temperature and Can be changed by diameter of a circle where the top of segmental arc in external force, it is identical with outer arc size.Meet or exceed memory temperature When and external force unloading after, the top of all interior segmental arcs drawn close to band center after where diameter of a circle revert to 1-4mm.

To prevent, closure folder is unexpected to come off, while more preferable closure effect can be reached, can also be set at the top of each interior segmental arc Detent projection is put, detent projection is towards closure folder center.

To further enhance closure effect, closure folder may also include the parallel folder consistent with outer arc segment number；Each is parallel Folder includes two clamps be arrangeding in parallel；Two fixing ends of clamp are connected with the two ends of outer arc segments respectively, its on-fixed end position In in the outer arc segments area defined.

To prevent, closing course is favorite to come off outward, can also be respectively arranged with geared assembly two relative sides of clamp. Geared assembly can have multiple structural forms, and three kinds of main structures are：

1st, geared assembly includes at least one pointed tooth of evagination, and pointed tooth staggers with the tine locations of relative clamp；Figure 41 In, each clamp includes two pointed tooths, and 4 pointed tooths of each closure folder are staggered.

The pointed tooth of the 2nd, groove of at least one pointed tooth of geared assembly including evagination and indent, and groove and relative clamp Quantity shape match, such as groove can be round and smooth groove, or V-shaped groove；In Figure 42, each clamp includes 2 points Tooth and 2 round and smooth grooves, pointed tooth are correspondingly arranged with the round and smooth groove on relative clamp.

3rd, geared assembly includes at least one round and smooth projection of evagination and the round and smooth groove and the round and smooth groove and phase of indent Round and smooth number of projection shape to clamp matches；In Figure 43, each clamp includes a round and smooth projection and a round and smooth groove.

Closure folder is clipped in tissue perforation internal orifice peripheral tissues, interior segmental arc or interior segmental arc with hyperelastic closure folder Treating anastomosed tissue internal orifice jointly with detent projection carries out Self-pressurizing agri, while pressurization, the group of the good side of blood circulation Scar proliferation is knitted, internal orifice is healed, reached hurtless measure and do not stayed the purpose of foreign matter in vivo.

Closure folder operation principle：The Ni-based marmem tissue closure folder of titanium, including by closing that the band for closing is constituted Co-clip main body；The band of closure is sequentially connected by the interior segmental arc head and the tail of staggered at least three outer arc segments and equal number； The band of closure forms plane layout, disk like layout or bowl-shape layout；Have when the band of closure is by higher than memory temperature super The Ni-based shape memory alloy material of titanium of elasticity is made, and its shape, external force can be changed during when external force effect or less than memory temperature Refresh memory shape when being higher than after unloading or again memory temperature.

The operation principle of the Ni-based marmem tissue closure folder of titanium make use of the Ni-based marmem of titanium Temperature effect and superlastic sexual function are pulled open under low temperature and external force effect, and closure reverts to shape memory under high temperature, with human body Hyperblastosis, the physiological Mechanism of necrosis are combined, and the design of titanium Ni-based marmem tissue closure clamping structure is reasonable Property, 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, The closure that can change with temperature or in outer masterpiece is pressed from both sides, its leading role for clinically implementing operation can be played.

Engaging tissue：It is semi-closure conjunction state that memorial alloy anal fistula internal orifice closure folder is remembered, closed-gap 1-2mm or so. The closure folder that will be closed 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 travels forward, and steel wire drives push ring to move downward, and will close folder and pushes to need at the tissue of closure.If necessary, with thin Line will organize colligation good, and silk thread is passed from through hole, tense, and pull tissue into closure folder, then cocking, release closure Folder, makes ring center clamp the tissue to be closed, and continues Self-pressurizing agri, tissue is tightly pushed down and is coincide.The tissue of pressurization because Blood circulation is good, and the hyperblastosis of pressurization forms cicatricial tissue and provides regeneration, reaches the purpose of engaging tissue.

Cutting tissue：It is fully closed condition by the closure folder memory of memorial alloy anal fistula internal orifice, remaining step is kissed with tissue Close identical.Tissue ischemia is caused in the ring of pressurization makes necrosis, while the one side necrosis of ring inner tissue, the outer another side of ring Hyperblastosis makes engaging tissue.Due to ring inner tissue ischemic necrosis, otch is formed, slough comes off, Ti-Ni shape memory is closed Gold closure folder also comes off therewith, and de- falling behind in excrete in the presence of enterocinesia, 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 is constant Pressure characteristic determine and can compensate different tissues thickness, and place tissue produced stablize lasting pressure, so as to ensure equal It is even with controllable compressed anastomosis process.Make the regeneration of engaging tissue portion within the different time, slough comes off, it is ensured that The reliability of engaging tissue.

What closure was pressed from both sides 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 temperature effect function of the Ni-based marmem of titanium is pulled open at low temperature, and closure reverts to shape memory under high temperature, with human body Hyperblastosis, the physiological Mechanism of necrosis were combined the organization healing time for ten days, folder is closed after ten days and comes off exclusion in vitro.Titanium nickel The design principle and design structure and clinical manipulation of base marmem tissue closure folder and use are all than current clinic institute Some peg stapling apparatus are more scientific, easier, are a preferable tissue closure binder tools.
