Abstract
The invention discloses a bone tunnel cross fixing pin for orthopedics ligament reconstructive surgery. The cross fixing pin comprises a connection part, a pointed part with a pointed protrusion is arranged on the end face of one end of the connection part, a tail part is arranged on the end face of the other end of the connection part, and the diameter of the tail part is consistent with that of the connection part. The pointed part is provided with an anti-receding groove with an opening towards the tail part. A blood supply groove is evenly formed around the axis of the connection part and in the outer side of the connection part. The tail part is provided with an anti-forwarding groove with an opening towards the pointed part. The fixing pin has the advantages that cross fixing is achieved, the fixing pin is firm and easy, operation time is shortened, and operation risk is reduced; the fixing pin is prevented from sliding or rotating after being fixed, and the fixing effect is guaranteed; the fixing pin has the blood supply groove function and provides an effective guarantee for healing between tendon and bone after the surgery.
Description
Technical field
The invention belongs to orthopaedics ligament reconstructive operation osseous tunnel internal ligament and cross fixed network, be specifically related to a kind of orthopaedics ligament reconstructive operation osseous tunnel and cross staple.
Background technology
Human body ligament refers to the dense connective tissue being attached to the interior or close juxtra-articular of articular cavity; It just needs operation to carry out reconstruction reparation once damage.
Currently used method is the ligament of inserting reconstruction after the former attachment point boring of ligament, then carries out the fixing of ligament by modes such as suture, holdfast, extrusion screws.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, provides a kind of orthopaedics ligament reconstructive operation osseous tunnel to cross staple, and structure is simple, easy to use, can guarantee safe implants material for doctor provides.
The technical solution adopted in the present invention is: a kind of orthopaedics ligament reconstructive operation osseous tunnel crosses staple, comprise connecting portion, described connecting portion wherein one end end face is provided with the tip with sharp protrusion, described connecting portion other end end face is provided with the diameter afterbody consistent with connecting portion, described tip has the anti-back groove of opening direction towards afterbody, evenly have blood supply groove around its axle center outside described connecting portion, described afterbody has the anti-pushing groove of opening direction towards tip.
As preferably, described staple length is 18mm ~ 48mm.
As preferably, described staple diameter is 1.8mm ~ 4.0mm.
As preferably, described staple material is the biomaterials such as BR, PLA.
As preferably, described blood supply groove is six.
Beneficial effect of the present invention is:
(1) cross fixing, firmly, simply, reduce operating time, reduce operation risk;
(2) fixing rear defence sliding stop and rotation, ensure fixed effect;
(3) there is blood supply groove function, for the healing between postoperative tendon and bone provides effective guarantee.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is that A-A of the present invention is to attempting.
In figure: 1, connecting portion; 2, tip; 3, afterbody; 4, anti-back groove; 5, blood supply groove; 6, anti-pushing groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of orthopaedics ligament reconstructive operation osseous tunnel crosses staple, comprise connecting portion 1, described connecting portion 1 wherein one end end face is provided with the tip 2 with sharp protrusion, described connecting portion 1 other end end face is provided with the diameter afterbody consistent with connecting portion 13, described tip 2 has the anti-back groove 4 of opening direction towards afterbody 3, evenly has blood supply groove 5 outside described connecting portion 1 around its axle center, and described afterbody 3 has the anti-pushing groove 6 of opening direction towards tip 2.
In the present embodiment, described staple length is 18mm ~ 48mm.
In the present embodiment, described staple diameter is 1.8mm ~ 4.0mm.
In the present embodiment, described staple material is the biomaterials such as BR, PLA.
In the present embodiment, described blood supply groove 5 is six.
The present invention can cross fixing, firmly, simply, reduces operating time, reduces operation risk; Fixing rear defence sliding stop and rotation, ensure fixed effect; There is blood supply groove 5 function, for the healing between postoperative tendon and bone provides effective guarantee.
Upper described embodiment only have expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
