Description

Technical Field

[0001] The invention relates to the technical field of sports medicine products, and in particular to an umbrella-shaped wire anchor. Background Art

[0002] In the clinical treatment application of Achilles tendon rupture repair, existing wire anchors mostly use structures such as threads, inverted teeth, and transverse limiting sheaths to fix the anchors in the human bone structure.

[0003] The disadvantages of the above-mentioned wire anchor are obvious. In the process of the anchor entering the human skeletal structure, the limiting structure (thread, inverted teeth, and lateral limiting sheath) has expanded the diameter of the installation positioning hole of the human skeletal structure, making it difficult to fix the anchor in the positioning hole. The anchor can easily detach from the positioning hole due to the continuous activity of the human body. Summary of the invention

[0004] The object of the present invention is to provide an umbrella-shaped belt wire anchor to solve the above technical problems.

[0005] The present invention is achieved in that:

[0006] An umbrella-shaped anchor with a line comprises an anchor body, a limiting rod, a connecting rod and a movable connecting seat; the limiting rod is hinged to the anchor body, one end of the connecting rod is hinged to the limiting rod, and the other end of the connecting rod is hinged to the movable connecting seat; the movable connecting seat is movably arranged on the anchor body, and the movable connecting seat can move along the length direction of the anchor body.

[0007] The design concept and working principle of the above-mentioned umbrella-shaped belt wire anchor are as follows:

[0008] The anchor body is hinged to the limit rod, and the angle between the two can be adjusted and changed. When inserted into the installation positioning hole, the angle between the two can be minimized or even parallel to each other, so as to facilitate insertion into the positioning hole without expanding the positioning hole. After being inserted into the installation positioning hole, the angle between the two can be larger to prevent the anchor body from escaping from the positioning hole. Among them, the angle adjustment between the anchor body and the limit rod can be achieved through the connecting rod and the movable connecting seat: when the connecting rod, the limit rod and the anchor body are placed in a relative position parallel to each other, the limit rod is attached to the anchor body; and when the anchor body is inserted into the positioning hole, the limit rod is swung relative to the anchor body around the hinge axis until the angle becomes larger, and the limit rod can play a limiting role to prevent the anchor body from coming out of the positioning hole. As the limit rod swings, the connecting rod also swings relative to the limit rod, and the movable connecting seat moves relative to the anchor body.

[0009] Furthermore, the movable connection seat is annular and sleeved outside the side wall of the anchor body. Its technical effect is that the annular movable connection seat not only limits the guide of its linear movement, but also can use the anchor body to form traction or support to swing the limit rod to a specific position. When there are multiple limit rods, the corresponding two limit rods also play a role of pushing each other.

[0010] Furthermore, the inner wall of the movable connection seat is provided with a guide tooth, and the outer wall of the anchor body is provided with a guide groove matched with the guide tooth. The technical effect is that the guide tooth and the guide groove can prevent the movable connection seat from rotating relative to the anchor body, avoid the situation where the limit rod rotates around the anchor body, and improve the structural stability of the anchor.

[0011] Furthermore, the cross section of the anchor body is rectangular, and the movable connection seat is a rectangular ring. The technical effect is that when the cross section of a section of the anchor body that moves relative to the movable connection seat is rectangular, and the movable connection ring sleeved on the outside is a mutually matching rectangular ring, the movable connection seat can also be prevented from rotating relative to the anchor body, avoiding the situation where the limit rod rotates around the anchor body, thereby improving the structural stability of the anchor.

[0012] Optionally, the movable connection seat is spherical, and the anchor body is provided with a groove extending along its length direction; the movable connection seat is built into the groove. Its technical effect is that when the size of the anchor body is large enough and the strength is hard enough, it is possible to avoid setting the movable connection seat on the periphery of the anchor body, and the movable connection seat is built into the groove of the anchor body. The spherical movable connection seat can realize the articulation of the limit rod and can also move along the anchor body.

[0013] Furthermore, it also includes a limit block; the limit block is arranged on the anchor body, and the limit block is located between the hinge point of the movable connection seat and the anchor body. Its technical effect is that when the limit rod swings to the maximum angle relative to the anchor body, the limit block can prevent the limit rod from continuing to swing and losing the limit effect on the anchor body. In addition, the position of the limit block can be set as needed to determine the most reasonable angle for the limit rod to swing relative to the anchor body.

[0014] Furthermore, when the movable connection seat abuts against the limit block, the connecting rod and the anchor body are perpendicular to each other. The technical effect is that after the anchor is positioned, the connecting rod is mainly subjected to tensile stress when fixing the anchor body, and when the movable connection seat abuts against the limit block, the connecting rod and the anchor body are perpendicular to each other, so that the tensile stress can only act on the movable connection seat and the relatively arranged connecting rod, thereby preventing the anchor body from being tilted unnecessarily.

[0015] Furthermore, there are multiple limit rods, which are evenly distributed around the circumference of the anchor body; the number of the connecting rods is equal to the number of the limit rods. The technical effect is that the uniform distribution of multiple limit rods is conducive to dispersing the clamping force of the anchor to each limit rod, further improving the fixing and installation effect of the anchor.

[0016] Furthermore, it also includes an anchor sleeve; the anchor sleeve is wrapped around the outside of the anchor body, the limiting rod, the connecting rod, the movable connecting seat and the limiting block. Its technical effect is that the anchor sleeve can limit the limiting rod, the connecting rod and the movable connecting seat on the anchor body when the limiting rod has not yet been unfolded and is tightly attached to the anchor body. It is convenient for the packaging and storage of the anchor.

[0017] Furthermore, the anchor body is provided with a threading hole, and the technical effect thereof is that the threading hole is used to fix the suture, so that the anchor can fix the implanted object.

[0018] The beneficial effects of the present invention are:

[0019] The umbrella-shaped anchor with wire of the present invention is provided with a limit rod on the anchor body that can be folded and stored through a connecting rod and a movable connecting seat. Before the anchor body enters the installation position, the limit rod is in a folded and stored state, which is conducive to the anchor body entering the human bone structure without expanding the installation hole; and after the anchor body enters the installation position, the limit rod is separated from the anchor body and is in an umbrella-shaped open state, which is conducive to fixing the anchor body at the installation position.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] First embodiment:

[0037] Figure 1 This is a schematic diagram of the structure of the umbrella-shaped belt wire anchor provided in the first embodiment of the present invention when it is closed. Figure 2 This is a schematic diagram of the structure of the umbrella-shaped belt wire anchor provided in the first embodiment of the present invention when it is opened. Figure 1 , Figure 2 The present embodiment provides an umbrella-shaped anchor with a wire, which includes an anchor body 1, a limiting rod 2, a connecting rod 3 and a movable connecting seat 4; the limiting rod 2 is hinged to the anchor body 1, one end of the connecting rod 3 is hinged to the limiting rod 2, and the other end of the connecting rod 3 is hinged to the movable connecting seat 4; the movable connecting seat 4 is movably arranged on the anchor body 1, and the movable connecting seat 4 can move along the length direction of the anchor body 1.

[0038] Furthermore, if Figure 1 , Figure 2 As shown, the movable connection seat 4 is annular and sleeved outside the side wall of the anchor body 1.

[0039] The design concept and working principle of the umbrella-shaped belt wire anchor are:

[0040] The anchor body 1 is hinged to the limiting rod 2, and the angle between the two can be adjusted and changed. When inserted into the installation positioning hole, the angle between the two can be minimized or even parallel to each other, so as to facilitate insertion into the positioning hole without enlarging the positioning hole. After being inserted into the installation positioning hole, the angle between the two can be larger to prevent the anchor body 1 from detaching from the positioning hole.

[0041] The angle adjustment between the anchor body 1 and the limiting rod 2 can be achieved through the connecting rod 3 and the movable connecting seat 4: when the connecting rod 3, the limiting rod 2 and the anchor body 1 are placed in a relative position parallel to each other, the limiting rod 2 is attached to the anchor body 1; and when the anchor body 1 is inserted into the positioning hole, the limiting rod 2 is swung relative to the anchor body 1 around the hinge axis until the angle becomes larger, and the limiting rod 2 can play a limiting role to prevent the anchor body 1 from coming out of the positioning hole. As the limiting rod 2 swings, the connecting rod 3 also swings relative to the limiting rod 2, and the movable connecting seat 4 moves relative to the anchor body 1.

[0042] Preferably, one end of the limiting rod 2 is hinged to the end of the anchor body 1, and the connecting rod 3 is hinged to the middle section of the limiting rod 2, so as to avoid the connection being located at the end of the limiting rod 2, and the movable connecting seat 4 is movably arranged in the middle section of the anchor body 1. When the limiting rod 2 is opened, the anchor body 1, the connecting rod 3 and the limiting rod 2 form a triangle, thereby improving the connection stability of the three.

[0043] In addition, the tip of the limit rod 2 may be sharpened.

[0044] Second embodiment:

[0045] Figure 3 This is a schematic diagram of the structure of the components related to the movable connection seat 4 in the umbrella-shaped belt wire anchor provided in the second embodiment of the present invention. Figure 3 The present embodiment provides an umbrella-shaped belt line anchor, which is substantially the same as the umbrella-shaped belt line anchor of the first embodiment. The difference between the two is that in the umbrella-shaped belt line anchor of the present embodiment, the inner wall of the movable connection seat 4 is provided with a guide tooth 5, and the outer wall of the anchor body 1 is provided with a guide groove 6 that cooperates with the guide tooth 5.

[0046] The guide teeth 5 are 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 teeth 5 can also be arranged on the outer wall of the anchor body 1, and the guide groove 6 is arranged on the inner wall of the movable connection seat 4. However, since the movable connection seat 4 itself has a small structural size, it is preferred to arrange the guide teeth 5 on the movable connection seat 4 for structural stability.

[0047] Third embodiment:

[0048] Figure 4 This is a schematic diagram of the structure of the components related to the movable connection seat 4 in the umbrella-shaped belt wire anchor provided in the third embodiment of the present invention. Figure 4 The present embodiment provides an umbrella-shaped belt line anchor, which is substantially the same as the umbrella-shaped belt line anchor of the first embodiment. The difference between the two is that the cross-section of the anchor body 1 in the umbrella-shaped belt line anchor of the present embodiment is rectangular, and the movable connecting seat 4 is a rectangular ring.

[0049] Optionally, the cross section of the anchor body 1 may also be in an elliptical, diamond-shaped or other non-rotationally symmetrical shape to prevent the movable connection seat 4 from rotating arbitrarily.

[0050] Fourth embodiment:

[0051] The present embodiment provides an umbrella-shaped belt line anchor, which is substantially the same as the umbrella-shaped belt line anchor of the first embodiment. The difference between the two is that the movable connection seat 4 in the umbrella-shaped belt line anchor of the present embodiment is spherical, and the anchor body 1 is provided with a groove extending along its own length direction; the movable connection seat 4 is built into the groove.

[0052] In this embodiment, when the size of the anchor body 1 is large enough and the strength is hard enough, it is possible to avoid setting the movable connection seat 4 on the periphery of the anchor body 1, and the movable connection seat 4 is built into the groove of the anchor body 1. The spherical movable connection seat 4 can not only realize the articulation of the limit rod 2, but also move along the anchor body 1.

[0053] Fifth embodiment:

[0054] Figure 5 A schematic diagram of the structure of the umbrella-shaped belt wire anchor provided in the fifth embodiment of the present invention when closed;

[0055] Figure 6 This is a schematic diagram of the structure of the umbrella-shaped belt line anchor provided in the fifth embodiment of the present invention when it is opened. Figure 5 , Figure 6 The present embodiment provides an umbrella-shaped belt line anchor, which is substantially the same as the umbrella-shaped belt line anchor in the first embodiment, the second embodiment, the third embodiment or the fourth embodiment. The difference between the two is that the umbrella-shaped belt line anchor in the present embodiment further includes a limit block 7; the limit block 7 is arranged on the anchor body 1, and the limit block 7 is located between the hinge point of the movable connecting seat 4 and the anchor body 1.

[0056] Furthermore, if Figure 6 As shown, when the movable connection seat 4 abuts against the limiting block 7, the connecting rod 3 and the anchor body 1 are perpendicular to each other.

[0057] When the limit rod 2 swings to the maximum angle relative to the anchor body 1, the limit block 7 can prevent the limit rod 2 from continuing to swing and losing the limiting effect on the anchor body 1. In addition, the position of the limit block 7 can be set as needed to determine the most reasonable angle for the limit rod 2 to swing relative to the anchor body 1.

[0058] In addition, after the anchor is positioned, the connecting rod 3 is mainly subjected to tensile stress when fixing the anchor body 1, and when the movable connecting seat 4 abuts the limit block 7, the connecting rod 3 and the anchor body 1 are perpendicular to each other, so that the above-mentioned tensile stress only acts on the movable connecting seat 4 and the relatively arranged connecting rod 3, thereby preventing the anchor body 1 from unnecessary tilting.

[0059] On the basis of any of the above embodiments, further, Figure 3 , Figure 4 As shown, there are multiple limiting rods 2 , which are evenly distributed around the circumference of the anchor body 1 ; and the number of connecting rods 3 is equal to the number of limiting rods 2 .

[0060] Figure 7 A schematic diagram of the structure of an umbrella-shaped belt line anchor provided in an embodiment of the present invention is provided with an anchor sleeve 8. Based on any of the above embodiments, further, as Figure 7 As shown, it also includes an anchor sleeve 8, which is wrapped around the anchor body 1, the limiting rod 2, the connecting rod 3, the movable connecting seat 4 and the limiting block 7, which is convenient for packaging and storage of the anchor.

[0061] On the basis of any of the above embodiments, further, Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, a threading hole 9 is provided on the anchor body 1 .

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
