Abstract
A compression fixing nail for single-tunnel double-bundle reconstruction of cruciate ligaments comprises a fixing body. The compression fixing nail is characterized in that the side face of the fixing nail body protrudes to form a splitting fin extending along the length direction of the fixing nail body; the upper end and the lower end of the big-end-up fixing nail body is in streamline smooth transition, and the cross section of the fixing nail body is water-drop-shaped; slip prevention teeth are formed on the upper section of the splitting fin. By the compression fixing nail for single-tunnel double-bundle reconstruction of the cruciate ligaments, the tendons can be close to anatomy stop-point stress areas, and requirements on anatomy reconstruction are met well; when the compression fixing nail is used together with a belt-carrier steel plate, the tendons are re-distributed at anatomy functional positions while good fixing force is guaranteed.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of staple of rebuilding for ligamentaum cruciatum list tunnel two-beam.
Background technology
Anterior cruciate ligament of knee joint under arthroscope (ACL) reconstruction operations has now become orthopedist's common recognition, but adopts single bundle or two-beam to rebuild, and still has and has many disputes.Many scholars think that two-beam reconstruction has good biological mechanics advantage, especially increases knee joint rotational stabilization.But also there is report to think that two-beam effect is effective unlike single bundle.It is to adopt twin tunnel two-beam to rebuild that two-beam is rebuild conventional method at present, but twin tunnel reconstruction needs femur end 2 Ge Gu roads, and technical difficulty is large, is difficult to judicious tunnel center position in art, and post-operative complication is more.It is a kind of technology that can meet two-beam ligament location that single tunnel two-beam is rebuild, and take at present Femoral Intrafix as representative, by a personal share osseous tunnel, after separation tendon, inserts nail sheath, screws in extrusion screw and fixes.But tendon is extruded the ridge away from resident after this technology is fixing, the normal ligament fibers that does not meet ACL distributes.ACL femur footprint is positioned at resident's ridge below extensive region, and the minimum intercondylar fossa lateral wall lower edge cartilage that extends to, can obviously distinguish AMB and PLB, intrafascicular visible bifurcated ridge of groups of people two.ACL fiber is by footprint periphery to the arrangement mode in footprint centralized, the function center footprint (fiber thick) of ACL two bundles is just in time positioned at the region under resident's ridge, and with resident's ridge runs parallel, show that resident's ridge is the upper bound of ACL two bundle footprints.Recover ACL completely and dissect the highest goal that footprint is clinical ACL reconstruction.How ligament is distributed during reconstruction function center under more close resident's ridge could better meet the function center of ligament, can better meet the physiological function of ligament.The reconstruction mode that also there is no at present a kind of the best, it is very significant developing the novel fixed form that effectively more meets ligamentaum cruciatum dissection footprint, functional requirement.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of single tunnel two-beam tendon that can adopt to rebuild the extruding staple of ligamentaum cruciatum, can make the more close dissection stop of tendon force area, better reach the requirement of Anatomical Reconstruction, coordinate belt loop steel plate to use, when guaranteeing good bed knife, tendon is redistributed in anatomical function position.
Object of the present invention realizes by following technical solution:
An extruding staple of rebuilding for ligamentaum cruciatum list tunnel two-beam, comprises staple body, it is characterized in that: described staple body side is protruded and is formed with a beam splitting fin extending along its length.
Further, streamlined seamlessly transitting between the large and upper and lower end in little upper end, described staple body lower end, its cross section is drops.
Further, described beam splitting fin epimere is formed with anti-slop serrations.
Further, described staple body is also formed with anti-slop serrations in the another side of relative beam splitting fin.
Further, described staple body upper surface is formed with " one " font locating slot of vertically extending positioning screw hole and horizontal expansion.
Further, described staple body is peek material, absorbable material or titanium alloy material.
The present invention has following beneficial effect:
The present invention can make ligament automatically be divided into front internal beam and rear external beam, by beam splitting fin, makes the more close dissection stop of two-beam tendon force area, can better reach the requirement of Anatomical Reconstruction.
The present invention coordinates belt loop steel plate to use, avoiding nail pulling risk to solve " bungee jumping effect " simultaneously, " rain brush effect " brings the problems such as tunnel face expansion.
Surgical technic difficulty of the present invention is significantly less than twin tunnel two-beam and rebuilds, also all multi-risk Systems that twin tunnel brings have been greatly reduced simultaneously, separating tendon simultaneously, give tendon in the certain extruding force of tunnel internal orifice, can not produce cutting to tendon again, increase effective bed knife of ligament, also increased the ability of tendon knitting simultaneously, met the fixing desirable requirement of ligament.
Streamlined seamlessly transitting between the large and upper and lower end in little upper end, staple body lower end, and cross section is drops, is convenient to, by tendon one side extruding to tunnel, conveniently enter nail simultaneously.
Staple arranges anti-slop serrations, and anti-slop serrations place diameter of a circle is slightly larger than tunnel diameter, can prevent staple rotation and nail pulling after placement staple; Staple upper surface arranges positioning screw hole, for being connected with the screw rod of specific purpose tool, can realize normally squeezing into and extracting of staple, gets nail convenient, residual without graft; Staple upper surface arranges locating slot, for the stop sleeve with specific purpose tool, clamps to prevent that screw rod relative localization screw from rotating.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further details.
Fig. 1 is front view of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is using state figure of the present invention.
The specific embodiment
Shown in Fig. 4, a kind of extruding staple of rebuilding for ligamentaum cruciatum list tunnel two-beam, comprise staple body 1, staple body 1 side is protruded and is formed with a beam splitting fin 11 extending along its length, streamlined seamlessly transitting between the large and upper and lower end in staple body 1 little upper end, lower end, its cross section is drops, beam splitting fin 11 epimeres are formed with anti-slop serrations 12, staple body 1 is also formed with in the another side of relative beam splitting fin 11 diameter that anti-slop serrations 13, two anti-slop serrations 12,13 place diameter of a circles are slightly larger than tunnel 4.
For operating the specific purpose tool of staple, comprise stick, be set on action bars and only can be along the axially movable stop sleeve of stick, stick front end is provided with the screw rod coordinating with positioning screw hole 14, stop sleeve can move between stop position and off-position, when stop sleeve is at stop position, the front end of stop sleeve snaps in and in locating slot 15, makes the screw rod of stick rotate by relative localization screw 14, to realize the implantation of staple; When stop sleeve is in off-position, the screw rod of stick can rotate by relative localization screw 14, to realize exiting of action bars, shown in Fig. 4, for the using state figure of staple, the beam splitting fin 11 of staple body 1 is divided into front internal beam 2 and rear external beam 3 by the tendon in tunnel 4.
The above, be only preferred embodiment of the present invention, therefore can not limit scope of the invention process with this, the equivalence of doing according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
