Problems solved by technology

[0003] The above-mentioned shortcoming of the threaded anchor is obvious. When the anchor enters the human skeletal structure, the limiting structure (thread, inverted tooth, lateral limiting sheath) has enlarged the caliber of the installation positioning hole of the human skeletal structure, resulting in positioning The hole is difficult to fix the anchor, and the anchor is easy to detach from the positioning hole due to the continuous movement of the human body

[0045] image 3 It is a schematic structural diagram of the relevant components of the movable connection seat 4 in the umbrella stripline anchor provided by Embodiment 2 of the present invention. Please refer to image 3 , this embodiment provides an umbrella-shaped anchor with wire, which is roughly the same as the umbrella-shaped anchor with wire in the first embodiment, the difference between the two is that the movable connection seat 4 in the umbrella-shaped anchor with wire in this embodiment The inner wall of the anchor body 1 is provided with a guide tooth 5, and the outer wall of the anchor body 1 is provided with a guide groove 6 matched with the guide tooth 5.

[0046] Wherein, the guide tooth 5 is arranged on the inner wall of the movable connection seat 4 , and the guide groove 6 is arranged on the outer wall of the anchor body 1 . Of course, the guide tooth 5 can also be arranged on the outer wall of the anchor body 1 , while the guide groove 6 is arranged on ...

[0048] Figure 4 It is a schematic structural diagram of the relevant parts of the movable connection seat 4 in the umbrella stripline anchor provided by the third embodiment of the present invention. Please refer to Figure 4 , this embodiment provides an umbrella-shaped anchor with wire, which is roughly the same as the umbrella-shaped anchor with wire in the first embodiment. The difference between the two is that the anchor body 1 in the umbrella-shaped anchor with wire in this embodiment The cross-section is rectangular, and the movable connection seat 4 is a rectangular ring.

[0049] Optionally, the cross-section of the anchor body 1 can also be in other non-rotationally symmetrical shapes such as ellipse and rhombus, so as to avoid arbitrary rotation of the movable connection seat 4 .

Abstract

The invention provides an umbrella-shaped rivet with a suture, and relates to the technical field of medical products. The umbrella-shaped rivet comprises a rivet body, a limiting rod, a connecting rod and a movable connecting seat, wherein the limiting rod is hinged to the rivet body, one end of the connecting rod is hinged to one end of the limiting rod, and the other end of the connecting rod is hinged to the movable connecting seat; and the movable connecting seat is arranged on the rivet body and can slide along the length direction of the rivet body. The limiting rod which can be foldably stored through the connecting rod and the movable connecting seat is arranged on the rivet body. The limiting rod is foldably stored before entering a mounting position and can advantageously entera human skeletal structure; and after the limiting rod enters the mounting position, the limiting rod and the rivet body are separated to form an umbrella-shaped strutting state, so that the rivet body is advantageously fixed at the mounting position.

Description

technical field [0001] The invention relates to the technical field of sports medicine products, in particular to an umbrella-shaped threaded anchor. Background technique [0002] In the clinical application of Achilles tendon rupture repair, the existing anchors with wires mostly use structures such as threads, inverted teeth, and lateral limiting sheaths to fix the anchors in the human bone structure. [0003] The above-mentioned shortcoming of the threaded anchor is obvious. When the anchor enters the human skeletal structure, the limiting structure (thread, inverted tooth, lateral limiting sheath) has enlarged the caliber of the installation positioning hole of the human skeletal structure, resulting in positioning It is difficult to fix the anchor in the hole, and the anchor is easy to be detached from the positioning hole because of the continuous activity of the human body. Contents of the invention [0004] The object of the present invention is to provide an umbr...
