Detailed Description
In order that the invention may be more readily understood, a more particular description of the invention will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Example 1:
referring to fig. 1, the present embodiment provides a flexible and recyclable anchor fixer, which includes a U-shaped body 100 and a fixing spring 200 sleeved on the U-shaped body 100.
The U-shaped structure body 100 is made of elastic and deformable materials so that the U-shaped structure body 100 is suitable for deformation; the U-shaped structural body 100 has a closed arcuate end 101 at one end and an open end 103 at the other end. The fixing spring 200 is sleeved on the outer circumference side of the opening end 103 of the U-shaped structure body 100 to fold the opening end 103 of the U-shaped structure body 100.
Optionally, the material of the U-shaped structural body 100 is NiTi alloy. The NiTi alloy is a resilient material such that the anchor deforms under the pulling action of the push wire 400.
It should be noted that, the U-shaped structure body 100 of the present embodiment is formed by bending a linear material to form a U-shaped structure, so two ends of the U-shaped structure body 100 formed after bending respectively form a closed arc end 101 and an open end 103, and the fixing spring 200 mainly has a function of restraining and folding the open end 103. The limit length of the fixing spring 200 accounts for 1/3 to 1/2 of the whole length of the U-shaped structure body 100, and the restraint folding effect of the opening end 103 of the U-shaped structure body 100 can be met. The fixing spring 200 itself has elasticity, so that the fixing spring 200 does not affect the deformation of the retainer along with the pulling of the push wire 400, but also can be synchronously and completely deformed along with the deformation of the retainer on the basis of realizing the restraining and folding effect on the opening end 103 of the U-shaped structure body 100.
For the connection between the fixing spring 200 and the U-shaped structural body 100, the fixing spring 200 is riveted with the U-shaped structural body 100 or fixedly connected with the U-shaped structural body 100 through high-viscosity adhesive, and of course, the fixing spring 200 and the U-shaped structural body 100 are also optionally fixedly connected with each other through welding.
Example 2:
referring to fig. 1, on the basis of the flexible and recoverable puncture anchor holder according to embodiment 1, this embodiment provides a flexible and recoverable puncture anchor, which specifically includes: the anchor of example 1, a recovery wire 300 attached to the arcuate end 101 of the anchor, and a push wire 400 partially attached to the inside of the U-shaped structural body 100 of the anchor. Wherein the recovery line 300 is a soft line.
Specifically, a channel 105 is formed between the open end 103 and the curved end 101 of the U-shaped structure, and the channel 105 is formed during bending of a linear material to form the U-shaped structure. The part of the pushing wire 400 fixedly connected with the U-shaped structure body 100 is accommodated in the channel 105; the pushing wire 400 is fixedly connected with the inner side wall of the channel 105 of the U-shaped structure body 100; the end of the push wire 400 that is attached to the U-shaped structure body 100 is proximal to the open end 103 of the U-shaped structure body.
Optionally, the push wire 400 is secured to the inner sidewall of the channel 105 by means such as, but not limited to, welding. The end of the push wire 400 may optionally be flush with the open end 103 of the U-shaped structure, or alternatively, the end of the push wire 400 may not be flush with the open end 103 of the U-shaped structure, for example, may be received in the channel 105 at a distance from the open end 103 of the U-shaped structure, and the embodiment is illustrated only in the case where the end of the push wire 400 is flush with the open end 103 of the U-shaped structure.
Optionally, since the pushing wire 400 needs to be pulled to deform the fixer, in order to make the fixer more stable in the deformation process, the turning part between the part of the pushing wire 400 accommodated in the channel 105 and the part located outside the U-shaped structural body 100 corresponds to the 1/2 length of the U-shaped structural body 100, so that after the fixer is sent into human tissue, the pushing wire 400 is pulled to force the middle part of the fixer, so that the whole fixer is bent and deformed from the middle part to two sides, namely, the arc-shaped ends 101 and the opening ends 103 distributed on two sides of the middle part of the fixer are deformed towards one side deviating from the pushing wire 400, so that the arc-shaped ends 101 and the opening ends 103 can be prevented from propping against the human tissue, and the damage of the fixer to the human tissue is reduced. Of course, the turning point between the portion of the pushing wire 400 accommodated in the channel 105 and the portion located outside the U-shaped structural body 100 may also correspond to the length of the U-shaped structural body 100 in other situations, for example, 1/3 of the length, that is, as long as the fastener can be caused to deform by the pulling action of the pushing wire 400 to meet the use requirement of the present embodiment, which is not limited in any way.
Referring to fig. 2, optionally, the pushing wire 400 is a hard wire with a certain pushing strength. And the surface of the hard silk thread is coated with the high polymer material coating 402, and the friction force during pushing can be reduced due to the arrangement of the high polymer material coating 402.
Optionally, the pushing wire 400 is a soft wire, and is pushed together with other instruments, and the pushing together with other instruments in this place belongs to a conventional technical means, which is not described in detail in this embodiment.
The specific embodiment of the flexible and recyclable puncture anchor holder of the present embodiment is as follows:
referring to fig. 3 to 5, under the guidance of an endoscope, an endoscopic puncture needle 1 (or other similar apparatus) punctures a tissue to a target position, then a push wire 400 of a puncture anchor is aligned with a holder, the holder is pushed out of the head end of the endoscopic puncture needle 1 (the end of the holder, which is not connected with a recovery wire 300, is advanced into the inner hole of the puncture needle 1) from the inner hole of the endoscopic puncture needle 1 by the push wire 400), then the holder is automatically in a vertical state with the push wire 400, the endoscopic puncture needle 1 is withdrawn, and the push wire 400 is pulled to pull and move the tissue to achieve the folding effect of the tissue and the tissue, and in this process, the holder is deformed along with the pulling of the push wire 400. Of course, the target tissue can be moved independently, thereby providing a convenient way for surgical treatment. After the operation is completed, the recovery wire 300 is pulled, and the anchor is automatically aligned with the recovery wire 300, thereby withdrawing the puncture anchor.
