Detailed Description
For a better understanding of the objects, structure and function of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.
Fig. 1-9 show the structure of a knotless anchor 100 according to an embodiment of the invention, comprising an anchor body 1, the anchor body 1 being formed with an axial central bore 11 extending axially through the anchor body 1, the anchor body 1 comprising a threaded connection section 12, the threaded connection section 12 being formed with at least one notch 13 on the edge of an external thread 124.
When the knotting-free anchor 100 is used, firstly, a positioning hole for implanting the knotting-free anchor 100 is formed in an anchor implantation position on a human bone, after a soft tissue to be fixed is fixed by a suture, the free end of the suture can penetrate through the knotting-free anchor 100, then, an external implantation instrument is used for implanting the knotting-free anchor 100 into the positioning hole which is formed in advance, so that the suture with the soft tissue fixed at one end is fixed in the positioning hole, namely, the soft tissue is fixed on the human bone.
Since the suture passing through the knot-free anchor 100 is located between the external thread 124 in the positioning hole and the human bone, the suture is easily cut off under the compression of the external thread 124 during the implantation of the anchor or when the suture is continuously tensioned after the implantation, while the knot-free anchor 100 of the embodiment has the notch 13 on the external thread 124 of the threaded connection section 12, so that even if the suture is compressed by the external thread 124, at least part of the suture is located in the notch 13 after the knot-free anchor 100 is implanted in the positioning hole, and the suture located in the notch 13 has a certain accommodating space relative to the suture directly compressed between the external thread 124 and the human bone, the risk of the suture being cut off can be reduced, thereby being beneficial to improving the fixing effect of the knot-free anchor 100.
It should be noted that the above-mentioned "passing the free end of the suture through the knotting-free anchor 100" may be to pass the free end of the suture through the axial center hole 11 and then to pull the free end of the suture between the external thread 124 in the positioning hole and the bone of the human body, or may be assisted by using an external component such as an additional anchor head, so that the free end of the suture passes through the anchor head and is pulled between the external thread 124 in the positioning hole and the bone of the human body (this embodiment with the aid of the anchor head will be described in detail later).
In the embodiment shown in fig. 1, 3, the external thread 124 may be configured to include a plurality of closed single-turn threads 125 formed at spaced intervals along the axial direction of the anchor body 1, each single-turn thread 125 having at least one notch 13 formed on an edge thereof. Often adopt among the prior art to have helical thread exempt from to tie an anchor, correspondingly adopt rotatory mode of implanting to implant exempting from to tie an anchor and plant the locating hole, at the rotatory in-process of exempting from to tie an anchor, the suture that is located exempt from to tie an anchor outer wall can be carried out more extrusion and cutting by the external screw thread at the rotatory in-process of anchor, and the suture is cut off more easily. Through this setting make external screw thread 124 form the multiple single-turn screw thread 125 of layering, when implanting exempting from to tie anchor 100, can carry out axial knocking to exempting from to tie anchor 100, beat exempting from to tie anchor 100 into the locating hole, at the in-process of knocking, exempting from to tie anchor 100 and be linear motion entering locating hole, consequently can reduce the risk that the suture is cut off by external screw thread 124.
In the embodiment shown in fig. 4 and 5, the external thread 124 may be configured as a full turn thread helically formed in the axial direction of the anchor body 1, and the portions of the turn thread located between the unit thread pitches may form single turns of the thread 125, each single turn of the thread 125 having at least one notch 13 formed on an edge thereof. By providing the notches 13 such that each single thread 123 forms an accommodating space for accommodating a suture when the knotless anchor 100 is implanted by rotation, the suture can be prevented from being squeezed and cut by the external thread 124 of the threaded connection section 12 in the entire length direction of the threaded connection section 12, and thus the fixing effect of the knotless anchor 100 can be further ensured.
As shown in fig. 1, 4, and 6-8, the notches 13 formed in each single turn thread 125 may be offset on the edge of the external thread 124. By this arrangement, after one part of the suture is compressed by the external thread of one single thread 125 at the outer edge of the knotting-free anchor 100, and then another part of the suture is positioned in the notch 13 of another single thread 125 adjacent to the one part of the suture, the compressed suture part is immovable, so that the strength of fixing the soft tissue and the human bone can be ensured, and the suture part positioned in the notch 13 has a certain accommodating space relative to the suture part directly compressed between the external thread 124 and the human bone, so that the risk of the suture being cut off can be reduced.
In addition, the notches 13 arranged on the edges of the external threads 124 of the single-turn threads 125 in a staggered manner enable the outer edges of the same single-turn thread 125 not to form a profile completely matched with the positioning hole, but after the notches 13 of the single-turn threads 125 are staggered, the outer edges of different single-turn threads 125 can be filled in an axial direction in a compensation manner, so that the knotting-free anchor 100 integrally has a radial outer profile more matched with the circular hole shape of the positioning hole, the knotting-free anchor 100 can be effectively connected with the human bone in the positioning hole, and the connecting strength is higher.
As shown in fig. 3 and 5, the notches 13 formed on each single turn of the thread 125 may be linearly arranged on the edge of the external thread 124. This setting makes the trend of suture on external thread 124 be the linear type, can conveniently walk the line and realize exempting from anchor 100 of knoing to the fine setting of suture after implanting the pilot hole, and simultaneously, the suture that is located in the notch 13 that is the linear type range also can not be cut by external thread 124 to ensure the fixed effect of exempting from anchor 100 of knoing.
In the embodiment shown in fig. 6, the difference from the embodiment shown in fig. 1 is that the threaded connection section 12 is further provided with a radial through hole 126 radially penetrating therethrough, and the radial through hole 126 can communicate with the axial center hole 11. Through this arrangement, the knotless anchor 100 has a plurality of threading methods, and thus can be applied to different situations of use. For example, the suture can be directly drawn to the outer surface of the threaded connecting section 12 to be fixed after passing through the axial center hole 11, or the suture can also be directly drawn to the outer surface of the threaded connecting section 12 to be fixed after passing through the radial through hole 126; alternatively, the suture may be drawn through the axial central bore 11 and/or the radial bore 126 in sequence and secured to the outer surface of the threaded connecting section 12.
Preferably, as shown in fig. 7, the anchor body 1 may further include an insertion section 14 coaxially connected to and integrally formed with the threaded connection section 12, and the insertion section 14 may further have at least one wire groove 15 formed on the outer peripheral wall thereof, and the wire groove 15 may communicate with the notch 13 on the single turn of the thread 125 closest to the insertion section 14 and extend out of the free end of the insertion section 14. The insertion section 14 is arranged to facilitate the knotting-free anchor 100 to be firstly positioned in the positioning hole, so as to facilitate the subsequent implantation; by providing the thread groove 15 such that when the suture is threaded from one end of the axial center bore 11, out the other end and drawn to the outer wall of the threaded connecting section 12, the suture can enter the thread groove 15 and be guided into the nearest recess 13 of the threaded connecting section 12 to ensure that the suture is not cut by the external thread 124 upon insertion of the anchor 100 into the predetermined pilot hole.
In an embodiment as shown in fig. 8, the threaded connection section 12 may include a first threaded connection section 121 near the insertion section 14 and a second threaded connection section 122 far from the insertion section 14, and the number of notches 13 of each single turn of the thread 125 located at the first threaded connection section 121 may be smaller than the number of notches 13 of each single turn of the thread 125 located at the second threaded connection section 122. The notches 13 are substantially notches formed at the edges of the external threads 124, so that the greater number of notches 13 weakens the structural strength and the fixing effect of the knot-free anchor itself, and the relatively smaller number of notches 13 of the single threads 125 of the first thread section 121 improves the structural strength and the fixing effect of the first thread section 121 to a certain extent because the first thread connecting section 121 is located deeper in the human bone when the knot-free anchor 100 is implanted into the positioning hole.
Preferably, the number of the recesses 13 of each single turn of the thread 125 of the first threaded connection section 121 may be 1.5 times to 2 times the number of the recesses 13 of each single turn of the thread 125 of the second threaded connection section 122.
In another preferred embodiment, the threaded connection section 12 may further include a third threaded connection section (not shown) between the first threaded connection section 121 and the second threaded connection section 122, and the number of the notches 13 of each single turn of the thread 125 of the third threaded connection section may be greater than the number of the notches 13 of each single turn of the thread 125 of the first threaded connection section 121 and less than the number of the notches 13 of each single turn of the thread 125 of the second threaded connection section 122. By this arrangement, the number of notches 13 at different positions of the threaded connection section 12 can be further refined, and a high connection strength between the threaded connection section 12 and the bone of the human body can be ensured while a high structural strength of the knotless anchor 100 is ensured.
