Abstract
The utility model discloses a metal interface screw for ligament is fixed, a metal interface screw for ligament is fixed wholly becomes toper, and the surface is covered by the screw thread, and inside is provided with the guiding hole that is used for passing the location apparatus, and the afterbody is provided with electric tool or apparatus complex hexagon socket head groove, the utility model discloses metal interface screw fixes ligament or substitute in bone tunnel through extruded mode, and easy operation has improved operation efficiency and fixed accuracy with the fixed degree of difficulty of ligament.
Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a metal interface screw for ligament is fixed.
Background
The cruciate ligament of knee, also called cruciate ligament, is located slightly posterior to the center of knee joint, is tough, and is lined by synovial membrane, which can be divided into anterior and posterior. The two ligaments cooperate to limit excessive knee motion.
When the athlete needs to quickly start, quickly stop and quickly change direction, the injury of the anterior cruciate ligament is very easy to happen to the athlete; the ACL laceration is difficult to repair by itself, and as the mechanical function of the anterior cruciate ligament is increasingly emphasized and the functional instability caused by injury causes the knee joint to fail to meet the needs of daily life and movement and can cause a series of sequela lesions of the knee joint, the operative treatment should be performed to reconstruct the ligament and the function thereof.
The need for ligament/substitute fixation in ligament reconstruction surgery is felt and therefore a need exists to provide an interface screw for ligament/substitute fixation that addresses the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve this problem, disclose a metal interface screw for ligament is fixed.
A metal interface screw for ligament fixation is characterized in that the metal interface screw (1) is integrally conical, the surface of the metal interface screw is covered by threads, a guide channel (3) for passing through a positioning instrument is arranged in the metal interface screw, and the tail part (5) of the metal interface screw is provided with an inner hexagonal groove (2) matched with an electric tool or instrument.
Preferably, the cross-sectional area of the whole interface screw (1) is gradually reduced from the tail part (5) of the metal interface screw to the head part (4) of the metal interface screw.
Preferably, the metal interface screw tail (5) leaves a smooth surface section that is partially unthreaded.
Preferably, the guide channel (3) is concentric with the inner hexagonal groove (2).
Preferably, the thread pitch of the surface of the metal interface screw for ligament fixation is uniform.
The utility model has the advantages of: the utility model discloses an extruded mode is fixed ligament or substitute in bone tunnel, easy operation, and the fixed degree of difficulty of ligament that has reduced has improved operation efficiency and fixed accuracy.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings and examples:
it should be noted that the structure, ratio, size and the like shown in the drawings of the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, and any modification of the structure, change of the ratio relationship or adjustment of the size should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the efficacy that the present invention can produce and the purpose that the present invention can achieve.
As shown in fig. 1 to 3, the detailed structure of the metal interface screw of the present invention is shown;
a metal interface screw for ligament fixation, the metal interface screw 1 is overall conical, the surface is covered by screw threads, a guide channel 3 for passing through a positioning instrument is arranged in the metal interface screw, and the tail part 5 of the metal interface screw is provided with an inner hexagonal groove 2 matched with an electric tool or instrument.
Preferably, the cross-sectional area of the interface screw 1 is gradually reduced from the metal interface screw tail 5 to the metal interface screw head 4.
Preferably, the metal interface screw tail 5 leaves a smooth surface section that is partially unthreaded.
Preferably, the guide channel 3 is concentric with the hexagonal socket 2.
Preferably, the thread pitch of the surface of the metal interface screw for ligament fixation is uniform
The utility model discloses a use: after the ligament or the substitute is placed at a proper position of the bone tunnel, the metal interface screw is sleeved into the guide rod, the head end of the metal interface screw is plugged into the entrance of the bone tunnel, an instrument is used for connecting the inner hexagonal groove 2 at the tail part of the metal interface screw, and the screw is screwed into the bone tunnel until the tail part is submerged into the entrance of the bone tunnel, so that the ligament or the substitute is fixed by the extrusion of the screw, and the effect of fixing the ligament or the substitute is achieved.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art.
Many other changes and modifications can be made without departing from the spirit and scope of the invention. It is to be understood that the invention is not to be limited to the specific embodiments, and that the scope of the invention is defined by the appended claims.
