Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a handle structure of a wire anchor inserter. Background Art

[0002] Existing inserter handles are generally in the form of having an internal hole or no hole. Generally, inserter handles with internal holes are suitable for anchor products with wires that require internal wires, while inserter handles without holes are suitable for anchor products with external wires or no wires.

[0003] At present, the sutures of wire anchor products in the domestic market are generally flat round or round, but due to the small diameter of the wire, there is a certain risk of cutting when fixing soft tissue. In order to avoid this risk, flat wire sutures can be used (here flat wire specifically refers to sutures with a width much greater than thickness) to increase the contact area between the suture and the soft tissue. However, at present:

[0004] 1. The handle of the inserter with an inner hole is generally limited by size, resulting in a smaller diameter of the inner hole, which has obvious restrictions on the type and number of sutures. Generally, the handle of the inserter with an inner hole cannot pass the flat wire or the small inner hole diameter causes the flat wire to be squeezed and deformed as a whole.

[0005] 2. The handle of the inserter without a hole cannot pass the wire, so it cannot meet the use requirements of the internal wire anchor. Utility Model Content

[0006] The utility model aims to provide a handle structure of a wire anchor inserter, which can meet the use requirements of an internal wire anchor.

[0007] The embodiment of the utility model is achieved as follows:

[0010] An open slot is arranged on the side wall of the driving part, and one end of the open slot passes through to an end of the driving part away from the rod body.

[0011] In an optional embodiment, the number of the open slot is at least one.

[0012] In an optional embodiment, when there are multiple open slots, the open slots are evenly arranged around the central axis of the rod body.

[0013] In an optional embodiment, the length of the opening slot is greater than or equal to the length of the driving portion.

[0014] In an optional embodiment, the cross-sectional shape of the opening groove is polygonal or semicircular.

[0015] In an optional embodiment, the open slot includes a line segment and a transition segment;

[0016] The line segment is arranged at an end of the opening slot away from the rod body, and the transition segment is arranged at an end of the opening slot close to the rod body;

[0017] One end of the line segment is connected to the end of the driving part away from the rod body, and the other end is connected to one end of the transition segment;

[0018] The other end of the transition section is connected to the side wall of the driving part or the side wall of the rod body.

[0019] In an optional embodiment, the groove bottom of the line segment is a plane, and the groove bottom of the transition segment is a plane or a curved surface.

[0020] In an optional embodiment, when the bottom surface of the transition section is a plane, a set angle is formed between the groove bottom of the transition section and the groove bottom of the line segment;

[0047] Combine the following Figures 1 to 10 , some embodiments of the present utility model are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] The utility model provides a handle structure of a wire anchor inserter, comprising a rod body 1 and a driving part 2; the length directions of the rod body 1 and the driving part 2 are consistent, and the driving part 2 is arranged at one end of the rod body 1; an open groove 3 is arranged on the side wall of the driving part 2, and one end of the open groove 3 passes through to the end of the driving part 2 away from the rod body 1.

[0049] In this embodiment, the driving part 2 is used to drive the anchor, and at least one driving surface is provided on its side wall. The driving surface can be a plane or an arc surface, which is used to cooperate with the driving groove on the anchor to realize the rotational drive of the anchor.

[0050] In this embodiment, an open groove 3 is provided on the side wall of the driving portion 2, and one end of the open groove 3 passes through the end of the driving portion 2, so that the suture on the wire anchor can extend to the outside through the open groove 3, so that the inserter handle does not need a threading hole, and due to the structural form of the open groove 3, the flat wire will not be squeezed and deformed, thereby meeting the use requirements of the internal wire anchor.

[0051] In this embodiment, in order to ensure the safety of the suture and prevent it from being worn off by the edges of the opening groove 3, the edges of the opening groove 3 are passivated.

[0052] Specifically, in the present embodiment, the edges of the opening groove 3 are rounded, and the risk of the suture being worn off is reduced by setting the rounded corners 3 - 3 .

[0053] In an optional embodiment, the number of the open slot 3 is at least one.

[0054] In this embodiment, the number of the opening slots 3 can be set according to usage requirements, and can be specifically set to one, two or even more.

[0055] When the number of the open slots 3 is set to be multiple, the suture can be connected to the anchor through any one of the open slots 3, or the anchor can be provided with multiple sutures.

[0056] In an optional embodiment, when there are multiple opening slots 3 , the opening slots 3 are evenly arranged around the central axis of the rod body 1 .

[0057] In this embodiment, when there are multiple opening grooves 3, the opening grooves 3 are evenly arranged around the outer wall of the driving part 2, and the center is the central axis of the rod body 1. In this arrangement, the edge stitches cooperate with the opening grooves 3.

[0058] In an optional embodiment, the length of the opening slot 3 is greater than or equal to the length of the driving part 2 .

[0059] In this embodiment, the transition period of the suture is increased by increasing the length of the opening groove 3, and the bending angle of the suture is reduced, thereby increasing the safety of the suture.

[0060] It should be understood that the length of the opening slot 3 should be set under the premise of ensuring the strength of the rod body 1 and the driving rod.

[0061] In an optional embodiment, the cross-sectional shape of the opening groove 3 is polygonal or semicircular.

[0062] In this embodiment, the cross-sectional shape of the opening groove 3 can be set to be a polygon or a semicircle.

[0063] Specifically, in this embodiment, when the cross-sectional shape of the opening groove 3 is a polygon, a rounded corner 3-3 is set between the bottom and the side wall of the opening groove 3, or between the edges of the polygon, to prevent the suture from being blocked by the angle and reduce the wear of the suture by the opening groove 3.

[0064] It should be pointed out that in the present embodiment, the shape of the opening groove 3 can be set to a polygon or a semicircle, but it is not limited to the above two shapes. It can also be set to other shapes, such as a semi-ellipse, etc. That is to say, as long as the setting of the opening groove 3 can facilitate the movement of the suture and will not affect the suture.

[0065] In this embodiment, the cross-sectional shape at any position of the opening groove 3 can be the same shape or different shapes, as long as the setting of the cross-sectional shape does not cause wear to the suture and does not affect the service life of the suture.

[0066] In an optional embodiment, the opening slot 3 includes a passing line segment 3-1 and a transition segment 3-2; the passing line segment 3-1 is arranged at an end of the opening slot 3 away from the rod body 1, and the transition segment 3-2 is arranged at an end of the opening slot 3 close to the rod body 1; one end of the passing line segment 3-1 is connected to the end of the driving part 2 away from the rod body 1, and the other end is connected to one end of the transition segment 3-2; the other end of the transition segment 3-2 is connected to the side wall of the driving part 2 or the side wall of the rod body 1.

[0067] In this embodiment, in order to ensure that the suture can be smoothly connected to the anchor and not affect the normal use of the suture and the anchor, the open groove 3 is set to a passing line segment 3-1 and a transition segment 3-2. The passing line segment 3-1 is connected to the anchor, and the transition segment 3-2 is connected to the passing line segment 3-1 and the outside of the rod body 1, forming a transition of the suture in the open groove 3.

[0068] In an optional embodiment, the groove bottom of the line segment 3 - 1 is a plane, and the groove bottom of the transition segment 3 - 2 is a plane or a curved surface.

[0069] In this embodiment, the bottom of the groove of the line segment 3 - 1 is set to be a plane, which can make the suture better connected with the anchor and make it easier for the suture on the anchor to pass through.

[0070] Specifically, in the present embodiment, the edges of the opening of the planar opening slot 3 of the line segment 3 - 1 are parallel, that is, the extending direction of the line segment 3 - 1 is consistent with the length direction of the driving part 2 .

[0071] In this embodiment, the groove bottom of the transition section 3 - 2 can be a flat surface or a curved surface, which can be set according to the strength of the rod body 1 and other design requirements.

[0072] In an optional embodiment, when the bottom surface of the transition section 3-2 is a plane, there is a set angle between the groove bottom of the transition section 3-2 and the groove bottom of the passing line segment 3-1; when the groove bottom of the transition section 3-2 is a curved surface, the curved surface is an arc surface.

[0073] In this embodiment, when the curved surface is an arc surface, the arc center of the arc is set in the opening direction of the opening groove 3.

[0074] In an optional embodiment, a groove bottom of the open groove 3 is provided with a wire opening 3-4 penetrating the rod body 1, and the wire opening 3-4 is arranged at an end of the transition section 3-2 away from the wire section 3-1.

[0075] In this embodiment, the transition section 3-2 of the open groove 3 can also be a mirror image direction of the axis, and a line opening 3-4 is set on the other side. At this time, the groove bottom of the transition section 3-2 is an arc surface, and the arc center is set in the direction away from the opening of the open groove 3.

[0076] This setting can ensure further management of the suture, make the position of the suture more stable, and reduce the possibility of suture swinging.

[0077] In an optional embodiment, the diameter or maximum width of the driving portion 2 is smaller than the diameter of the rod body 1, and a stepped groove can be formed on the side wall of the handle structure of the wire anchor inserter.

[0078] The beneficial effects of the embodiments of the utility model are:

[0079] By providing an open groove 3 on the side wall of the driving part 2, the wire passing requirement can be achieved without squeezing the flat wire during use, thereby meeting the implantation requirement of the inner wire anchor.
