Description
Technical Field
The invention relates to the technical field of sports medicine products, in particular to an umbrella-shaped anchor with a wire.
Background
In clinical treatment application of achilles tendon fracture repair, the conventional threaded anchor is fixed in a human bone structure by utilizing structures such as threads, inverted teeth and a transverse limiting sheath.
The above-mentioned disadvantages of the anchor with thread are obvious, and in the process of entering the human skeleton structure, the limit structure (thread, pawl, transverse limit sheath) has enlarged the aperture of the installation location hole of the human skeleton structure, which causes the location hole to be difficult to fix the anchor, and the anchor is easy to be separated from the location hole due to the continuous activity of human body.
Disclosure of Invention
The invention aims to provide an umbrella-shaped anchor with a line, which aims to solve the technical problem.
The invention is realized by the following steps:
an umbrella-shaped anchor with a wire comprises an anchor body, a limiting rod, a connecting rod and a movable connecting seat; the limiting rod is hinged with the anchor nail body, one end of the connecting rod is hinged with the limiting rod, and the other end of the connecting rod is hinged with the movable connecting seat; the movable connecting seat is movably arranged on the anchor bolt body and can move along the length direction of the anchor bolt body.
The design concept and the working principle of the umbrella-shaped anchor with the line are as follows:
the anchor body is articulated with the gag lever post, and contained angle between the two is adjustable and change, when inserting the installation locating hole, can be the minimum angle or even both are parallel to each other with above-mentioned contained angle between them to do benefit to and put into the locating hole under the condition that does not enlarge the locating hole, and after inserting the installation locating hole, above-mentioned contained angle between the two can present greatly, prevents that the anchor body from breaking away from in the locating hole. Wherein, the contained angle adjustment of anchor body and gag lever post can be realized through connecting rod and swing joint seat: when the connecting rod, the limiting rod and the rivet body are placed in parallel relative positions, the limiting rod is attached to the rivet body; and after the anchor body is inserted into the positioning hole, the limiting rod swings to the larger included angle relative to the anchor body around the hinge shaft, and the limiting rod can play a limiting role to prevent the anchor body from coming out of the positioning hole. And along with the swinging of the limiting rod, the connecting rod swings relative to the limiting rod immediately, and the movable connecting seat moves relative to the rivet body.
Further, the movable connecting seat is annular and is sleeved outside the side wall of the anchor bolt body. The technical effects are as follows: the annular movable connecting seat not only limits the guide of the linear movement of the movable connecting seat, but also can utilize the anchor body to form traction or support to swing the limiting rod to a specific position. When the number of the limiting rods is multiple, the two corresponding limiting rods also play a role in mutual pushing.
Furthermore, the inner wall of the movable connecting seat is provided with guide teeth, and the outer wall of the anchor bolt body is provided with guide grooves matched with the guide teeth. The technical effects are as follows: lead tooth and guide slot and can prevent that the swing joint seat from rotating for the anchor body, avoid appearing the gag lever post around the pivoted condition of anchor body, improve the structural stability of anchor.
Further, the cross section of the anchor body is rectangular, and the movable connecting seat is a rectangular ring. The technical effects are as follows: when the cross section of one section anchor body for the swing joint seat removes is the rectangle, and cup joint when the swing joint ring in the outside is the rectangle ring of mutually supporting, can prevent equally that the swing joint seat from rotating for the anchor body, avoids appearing the gag lever post around the pivoted condition of anchor body, improves the structural stability of anchor.
Optionally, the movable connecting seat is spherical, and the anchor body is provided with a groove extending along the length direction of the anchor body; the movable connecting seat is arranged in the groove. The technical effects are as follows: when the enough big intensity of size of anchor body is enough hard, can avoid setting up the swing joint seat in the periphery of anchor body, and embed the swing joint seat in the recess of anchor body, the swing joint seat of spheroid shape can enough realize the articulated of gag lever post, can also follow the anchor body and remove.
Furthermore, the device also comprises a limiting block; the limiting block is arranged on the anchor body and is positioned between the movable connecting seat and a hinge point of the anchor body. The technical effects are as follows: when the limiting rod swings to the maximum angle relative to the anchor body, the limiting block is arranged to prevent the limiting rod from continuously swinging to lose the limiting effect on the anchor body. And, can set for the position of stopper as required to confirm the most reasonable angle that the gag lever post swung for the anchor body.
Further, when the movable connecting seat abuts against the limiting block, the connecting rod is perpendicular to the anchor nail body. The technical effects are as follows: the connecting rod mainly receives the tensile stress when the effect of fixed anchor nail body after anchor location, and when the swing joint seat butt stopper, connecting rod and anchor nail body mutually perpendicular can make above-mentioned tensile stress only act on the connecting rod of swing joint seat and relative setting, prevents that the anchor nail body from taking place the unnecessary slope.
Furthermore, the number of the limiting rods is multiple, and the multiple limiting rods are uniformly distributed around the circumferential direction of the anchor bolt body; the number of the connecting rods is equal to that of the limiting rods. The technical effects are as follows: a plurality of gag lever posts evenly distributed do benefit to in the chucking effort dispersion of with the anchor reaches each gag lever post, further improves the fixed mounting effect of anchor.
Further, the anchor rod further comprises an anchor sleeve; the anchor sleeve is wrapped on the outer sides of the anchor body, the limiting rod, the connecting rod, the movable connecting seat and the limiting block. The technical effects are as follows: the anchor sleeve can limit the limiting rod, the connecting rod and the movable connecting seat on the anchor body when the limiting rod is not unfolded and is tightly attached to the anchor body. The packing and the storage of convenient anchor nail.
Furthermore, a threading hole is formed in the anchor bolt body. The technical effects are as follows: the threading hole is used for fixing a thread, so that the anchoring nail can fix an implanted object.
The invention has the beneficial effects that:
the invention relates to an umbrella-shaped anchor with a wire, wherein a limiting rod which can be folded and stored through a connecting rod and a movable connecting seat is arranged on an anchor body. The limiting rod is in a folding and accommodating shape before the anchor body enters the installation position, so that the anchor body can conveniently enter the bone structure of the human body without expanding the installation hole; and after the anchor body enters the installation position, the limiting rod and the anchor body are separated to be in an umbrella-shaped opening state, so that the fixation of the anchor body at the installation position is facilitated.
