Abstract
The invention discloses a kind of nail foot fixer made of memory alloy, it is carried on the back including cuved nail, the both ends of cuved nail back are respectively equipped with nail pin, nail pin and the material of cuved nail back are memorial alloy and nail pin and cuved nail antiform into a ring structure, the inside of cuved nail back is equipped with multiple fixed teeth, and the inside of nail pin is equipped with multiple anti-skidding pawls.Anti-skidding pawl of the invention enhances fixator in the stability of the fixed position of ligament, deviates from after preventing fixator to be implanted into；Fixed dental transition further enhances the fixation of ligament, and ligament is fixed.In addition, two nail pins are unfolded after using memorial alloy material, when operation to be fully cooled by the present invention, notch, remove tissue, reduction ligament, fixing holder, hot compress fixator after installation, two nail pins reset, and repair so that ligament is fixed, and memory alloy material biocompatibility is preferable, conducive to knitting is suffered from.Easy to operate in surgical procedure, operating time is short, and wound face is small, postoperation recovery is fast, effectively improves life in patients.
Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of nail foot fixer made of memory alloy.
Background technique
Human body ligament is the primary condition for maintaining joint stability, it had not only limited the scope of activities in joint, but guidance joint according to
It is moved according to certain rule, that is, ligament felt incoming by nerve, cause respective muscle reflexively by tension when movement
Contraction maintain joint in the movement of three axial directions to limit the movable ligament in joint in one figure of eight structure of intra-articular formation
Stablize, while ligament intersects again, the anatomical features for being located at articulation center and bony structure complements each other, and common guidance is closed
According to a certain direction, certain rule moves section.Because external force or movement caused by rupture of ligament, will lead to joint cannot be normal
Movement, will lead to joint instability if not treating, cartilage wear, the symptoms such as osteoarthritis.Common operative treatment scheme is ligament
Suture is fixed, screw is fixed, but operating time is long in ligament fixation procedure at present, and operation wound face is big, and postoperation recovery is slower.
Summary of the invention
The purpose of the present invention is to solve the technical problems existing in the prior art, provide that a kind of structure is simple, operation
The nail foot fixer made of memory alloy convenient, ligament is fixed, operating time is short, wound face is small, postoperation recovery is fast.
In order to achieve the above object, the invention adopts the following technical scheme: a kind of nail foot fixer made of memory alloy, including arc
Staple back, the both ends of cuved nail back are respectively equipped with nail pin, the material of the nail pin and cuved nail back be memorial alloy and
At a ring structure, the inside of the cuved nail back is equipped with multiple fixed teeth, the inside of the nail pin for nail pin and cuved nail antiform
Equipped with multiple anti-skidding pawls.
Further, the nail pin is structure as a whole with cuved nail back.
Further, the end of the nail pin is cusp-shaped or square toes shape.
Further, the radius of the cuved nail back is 10-150mm.
Further, the fixed tooth is 1-20.
The present invention has the advantages that nail foot fixer made of memory alloy of the present invention mainly by material compared with the prior art
For the cuved nail back and nail pin composition of memorial alloy, cuved nail, which is carried on the back, forms one with two nail pins that cuved nail back both ends are arranged in
Anti-skidding pawl is arranged in the inside of two nail pins in ring structure, enhances fixator in the stability of the fixed position of ligament, prevents
Deviate from after fixator implantation；Fixed tooth is set in the inside of cuved nail back, further strengthens the fixation of ligament, ligament is fixed
It is firm.In addition, cuved nail of the present invention back and nail pin use memorial alloy material, when operation be fully cooled after two nail pins are unfolded
It is parallel to two nail pins, to notch at rupture of ligament, tissue is removed, reduction ligament installs nail foot fixer made of memory alloy, after installation
Hot compress fixator, two nail pins of fixator reset so that ligament is fixedly secured reparation, and memory alloy material biocompatibility compared with
It is good, conducive to knitting is suffered from.Not only make the firm fixation of ligament in entire surgical procedure, but also is implanted into surgical procedure, takes out behaviour
Facilitate, operating time is short, and wound face is small, postoperation recovery is fast, effectively improves life in patients.
Detailed description of the invention
The structural schematic diagram that Fig. 1 is nail pin end of the invention when being cusp-shaped；
Fig. 2 is the side view of Fig. 1；
The structural schematic diagram that Fig. 3 is nail pin end of the invention when being square toes shape；
Fig. 4 is the side view of Fig. 3.
Appended drawing reference meaning of the present invention is as follows: 1, cuved nail is carried on the back；2, nail pin；3, fixed tooth；4, anti-skidding pawl.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
As shown in Figs 1-4, a kind of nail foot fixer made of memory alloy, including the cuved nail back 1 that radius is 10-150mm, arc
The both ends of nail back 1 are respectively equipped with nail pin 2, and the end of nail pin 2 is cusp-shaped or square toes shape, and two nail pins 2 and cuved nail back 1 are one
The material of body structure, nail pin 2 and cuved nail back 1 is that memorial alloy and nail pin 2 and cuved nail back 1 form a ring structure, arc
The inside of staple back 1 is equipped with 1-20 fixed tooth 3, and the inside of nail pin 2 is equipped with multiple anti-skidding pawls 4.Wherein, by the end of nail pin 2
Portion is made into cusp-shaped, be in order to by nail foot fixer made of memory alloy quickly, easily directly squeeze into bone；By the end of nail pin 2
Portion is made into square toes shape, is installed after punching on bone when cannot directly squeeze into bone for nail foot fixer made of memory alloy.
2 end of nail pin is that the nail foot fixer made of memory alloy application method of cusp-shaped is as follows: by memoryalloy pin when operation
Foot fixator, which is put into sterile brine ice, is allowed to after being fully cooled that nail pin 2 is expanded to two nail pins with specific purpose tool in brine ice
