Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a flexible wire hole with wire anchor assembly. Background Art

[0002] At present, in the repair technology of fixing soft tissue to bone, anchors are mostly used to fix sutures. The suture passes through the hole at the end of the anchor and is squeezed into the bone canal by the anchor to achieve the purpose of fixation. The anchor is a human implant, so it is expected that the bone will be minimally damaged and injured during its implantation.

[0003] Most of the commonly used anchors are structures with threading holes at the ends, and the overall length is fixed. When pre-drilling the bone, a bone tunnel that is suitable for the length of the anchor needs to be drilled.

[0004] Although the prior art has used a deformable wire loop to replace the anchor end, so that the length of the anchor can be shortened, thereby avoiding drilling a deeper bone tunnel, but in fact, after the coil is tightened, a wire knot will be formed, occupying the space of the bone tunnel, and after the wire loop is self-locking, the traction wire is pulled out, and the wire loop is in a free state near the nail body end. It is possible that during human activities, the wire loop will become loose, thereby weakening the restraint on the soft tissue suture; the structure of the traction wire and the wire loop being integrally formed requires the excess part of the traction wire to be cut off after self-locking is achieved. Under arthroscopy, this operation increases the operation time and cost.

[0005] In addition, currently, anchors are implanted into bone canals mostly by delivery with an inserter, which usually has an inner shaft and an outer shaft. The anchor is screwed into the bone canal by rotating the inner shaft. However, during this process, the wire loop does not rotate with the inserter, and the rotation of the inner shaft will wear the wire loop, increasing the risk of wire loop failure. Utility Model Content

[0023] In an optional embodiment, the traction wire passes through the interior of the inserter and is connected to the single-wire structure.

[0024] The beneficial effects of the embodiments of the utility model are:

[0025] After the wire loop of the flexible self-locking knot shrinks, it can be hidden in the inner hole where the nail body and the wire knot are in contact, so that the overall length of the rigid anchor and the flexible wire knot is reduced, which can truly shorten the depth of the pre-drilled hole in the bone channel, reduce bone loss, and facilitate patient recovery; at the same time, the wire loop is a fully enclosed structure, which completely binds the suture, and can be hidden in the end of the nail body after shrinking, so as to achieve the effect of completely fixing the suture; the traction line is an independent and removable structure.

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

[0046] Combine the following Figures 1 to 12 , 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.

[0047] The utility model provides a flexible wire hole with wire anchor assembly, such as Figure 1 As shown, it includes a nail body 1, a flexible self-locking structure 3, a traction line 5 and an inserter 2; the inserter 2 passes through the nail body 1 from one end of the nail body 1 and is connected to the flexible self-locking structure 3; the flexible self-locking structure 3 includes a wire sleeve 11 and a wire loop, the wire loop is a closed double-wire loop structure, wherein one end of the wire loop is a single-wire structure 9, and the other end of the wire loop is a double-wire structure 10, the wire sleeve 11 is sleeved on the double-wire structure 10, and the double-wire structure 10 forms a threading hole 12 for the suture 4 to pass through; the traction line 5 is connected to the single-wire structure 9 of the wire loop, and can pull the double-wire structure 10 of the wire loop to shrink in the wire sleeve 11.

[0048] In this embodiment, the inserter 2 drives the nail body 1 to rotate. An external thread is provided on the outer wall of the nail body 1, which can be screwed into the bone canal 8 under the drive of the inserter 2.

[0049] The flexible self-locking structure 3 follows the end of the inserter 2 into the bone tunnel 8. After the nail body 1 enters the bone tunnel, the flexible self-locking structure 3 is pulled into the end of the nail body 1 by the traction line 5, and the suture 4 is locked by the flexible self-locking structure 3, thereby achieving anchoring of the suture 4.

[0050] After the suture 4 passes through the threading hole 12 of the flexible self-locking structure 3, it is implanted into the bone tunnel 8 together with the flexible self-locking structure 3. When necessary, the traction line 5 pulls the single-line structure 9 to contract the double-line structure 10 of the flexible self-locking structure 3 to fix the suture 4.

[0051] The existing self-locking structure is open, and the thread loop is in a free state. It is possible that during human activities, the thread loop becomes loose, and the restraining force on the soft tissue suture is weakened.

[0052] In this embodiment, the flexible self-locking structure 3 is arranged at the end of the inserter 2, and enters the end of the nail body 1 after the traction wire 5 is pulled, so that the total length of the rigid anchor and the flexible wire knot is reduced, the pre-drilling depth of the bone channel 8 is shortened, the bone loss is reduced, and the patient's recovery is facilitated.

[0053] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the flexible self-locking structure 3 is a closed double-wire ring structure, and one end of the double-wire ring structure is a single-wire structure 9, and the other end is a double-wire structure 10, which is equivalent to putting the wire around the ring with one end aligned and the other end not aligned, and then partially positioning the double-wire structure 10 through the wire sleeve 11 to prevent the double-wire structure 10 from being separated into the single-wire structure 9, and the through hole formed in the double-wire structure 10 is used as a threading hole 12, and the suture 4 is set through the threading hole 12, and the single-wire structure 9 is connected to the traction line 5. Through the traction of the traction line 5, one end of the single-wire structure is driven to move away from the double-wire structure 10, so that the double-wire structure 10 shrinks. Due to the existence of the wire sleeve 11, the double-wire structure 10 will not be dispersed into a single wire, but the threading hole 12 will become smaller through shrinkage, and finally shrink together to fix the suture 4, thereby forming a locking effect on the suture 4.

[0054] When the traction line 5 completes traction on the flexible self-locking structure 3 , it can be pulled out from the single-line structure 9 .

[0055] The whole process is simple and convenient to operate, and there is no need to cut the traction line 5 separately, thereby improving the operating efficiency.

[0056] The flexible self-locking knot of the utility model is in a fully closed state, completely restraining the suture 4, and after shrinking, it cooperates with the concealable anchor nail in this embodiment to completely fix the suture 4.

[0057] In an optional embodiment, a mounting groove 7 is provided at the end of the nail body 1, and the mounting groove 7 is used to accommodate the flexible self-locking structure 3 after traction; the mounting groove 7 is coaxial and connected to the inner hole 6 of the nail body 1; in the axial section of the nail body 1, the mounting groove 7 and the inner hole 6 together constitute a T-shaped hole structure, and in the same axial section, the width of the mounting groove 7 is greater than the width of the inner hole 6.

[0058] In this embodiment, a mounting groove 7 is provided at the end of the nail body 1, the bottom of the mounting groove 7 is connected to the inner hole 6, and a step structure is formed between the groove wall of the mounting groove 7 and the side wall of the inner hole 6, that is, in the axial section of the nail body 1, the mounting groove 7 and the inner hole 6 together constitute a T-shaped hole structure, and in the same axial section, the width of the mounting groove 7 is greater than the width of the inner hole 6.

[0059] In order to prevent the flexible self-locking structure 3 from detaching from the inner hole 6 of the nail body 1, the width of the flexible self-locking structure 3 after contraction is larger than the maximum hole diameter of the inner hole 6, and can be placed in the mounting groove 7, so that the flexible self-locking mechanism 3 can be hidden at the end of the nail body 1, and the flexible self-locking structure 3 can be prevented from entering the inner hole 6.

[0060] In this embodiment, on the axial cross-section of the nail body 1, the mounting groove 7 and the inner hole 6 form a T-shaped hole structure, so that the contact point between the nail body 1 and the flexible self-locking structure 3 is the mounting groove 7 with a large diameter. Therefore, the flexible self-locking structure 3 can be hidden in the mounting groove 7 after shrinkage, while being constrained by the inner hole 6 with a small diameter.

[0061] In an optional embodiment, in the radial cross section of the nail body 1 , the shape of the mounting groove 7 is the same as the shape of the inner hole 6 .

[0062] In this embodiment, in the radial cross section of the nail body 1, the shapes of the mounting groove 7 and the inner hole 6 are both quadrilateral or hexagonal.

[0063] Such a configuration can facilitate the inserter 2 to drive the nail body 1 and drive the nail body 1 to rotate.

[0064] It should be pointed out that the shape of the mounting groove 7 and the shape of the inner hole 6 can be a quadrilateral or a hexagon, but it is not limited to a quadrilateral or a hexagon. It can also be other types of hole groove structures, such as a pentagon, a triangle, etc., or it can be set to an ellipse, a semicircle, or other shapes that can be driven.

[0065] In an optional embodiment, the traction line 5 and the single-line structure 9 are connected in a detachable manner.

[0066] In the prior art, the traction wire and the self-locking wire ring are an integrated structure. After self-locking is achieved, the excess part of the traction wire needs to be cut off. Under arthroscopy, this operation increases the operation time and cost.

[0067] In this embodiment, the connection between the traction wire 5 and the single-wire structure 9 is a detachable connection, and the traction wire 5 and the flexible self-locking structure 3 are two independently set structures. During the operation, the traction wire 5 is pulled, and after the flexible self-locking structure 3 contracts, the traction wire 5 can be pulled out, which simplifies the surgical operation.

[0068] There are many ways to detachably connect the traction line 5 and the single-line structure 9.

[0069] Specifically, in the present embodiment, the traction line 5 and the single-line structure 9 are connected by threading, that is, one end of the traction line 5 passes through the gap between the single-line structure 9 and the double-line structure 10, and then merges with the other end, so that the single-line structure 9 can be pulled, thereby driving the single-line structure 9 to move, and when one end of the traction line 5 is loosened, the traction line 5 can be pulled out from the unidirectional structure, thereby facilitating the separation of the traction line 5 and the single-line structure 9.

[0070] This arrangement makes the flexible self-locking structure 3 and the traction wire 5 independent of each other. The size of the threading hole 12 in the flexible self-locking structure 3 is controlled by the traction of the traction wire 5. After the implantation is completed, the traction wire 5 can be pulled out, and the closed structure in the flexible self-locking structure 3 is not affected. This not only reduces the operating steps of the traction wire 5 in arthroscopic surgery, but also has a continuous fixed constraint force on the external suture 4.

[0071] It should be pointed out that in the present embodiment, the connection method between the traction line 5 and the single-line structure 9 is threading, but it is not limited to this setting method. It can also be other connection methods, as long as it can achieve the independence of the traction line 5 and the flexible self-locking structure 3 and facilitate the separation of the traction line 5 and the flexible self-locking structure 3.

[0072] In an optional embodiment, the inserter 2 includes an inner tube 13, an outer tube 14, a first handle 15 and a second handle 16; the first handle 15 is fixedly arranged at one end of the outer tube 14, the outer tube 14 and the first handle 15 are both arranged outside the inner tube 13, and the other end of the outer tube 14 is inserted into the inner hole 6 of the nail body 1 to drive the nail body 1 to rotate; the second handle 16 is fixedly arranged at one end of the inner tube 13.

[0073] In this embodiment, the outer tube 14 of the inserter 2 is connected to the nail body 1 , and can drive the outer tube 14 to rotate under the action of the first handle 15 , thereby driving the nail body 1 to rotate, so that the nail body 1 can enter the bone canal 8 .

[0074] During the process of implanting anchors into bone tunnels, the inner tube of the existing inserter is the moving part, and the self-locking wire loop is connected to the inner tube of the inserter. Therefore, the wire loop rotates with the rotation of the inner tube during the entire implantation process, and the contact surface is always in a friction state, increasing the risk of wire loop failure.

[0075] In this embodiment, the moving part of the inserter 2 is designed as an outer tube 14, and the inner tube 13 and the outer tube 14 are sleeved together. Through the coordination of the tube diameter shape, the anchor implantation is completed under the action of the first handle 15; and the rotation of the outer tube 14 will not drive the inner tube 13 to rotate. During the implantation process, the wire loop contacts the inner tube 13 but does not move, and the wire loop will not be worn, thereby ensuring the use effect of the flexible self-locking structure 3.

[0076] In an optional embodiment, the inner tube 13 and the outer tube 14 are threadedly connected.

[0077] In this embodiment, the connection between the inner tube 13 and the outer tube 14 is a threaded connection, so that when the inner tube 13 is stationary, the outer tube 14 can rotate and move axially relative to the inner tube 13, thereby driving the nail body 1 to rotate and move axially, so that the nail body 1 can enter the bone canal 8.

[0078] In an optional embodiment, the outer contour of the radial cross section of the end of the outer tube 14 close to the nail body 1 is a quadrilateral or a hexagon, and matches the shape of the inner hole 6 of the nail body 1 .

[0079] In this embodiment, the overall outer contour of the outer tube 14 is a cylinder, and the end thereof close to the nail body 1 is configured as a quadrangular prism or a hexagonal prism matching the inner hole 6, forming a driving end 17, which can facilitate the rotation of the outer tube 14 without affecting the human body, and can also drive the nail body 1 to rotate, thereby achieving the purpose of sending the nail body 1 into the bone channel 8.

[0080] In an optional embodiment, the outer contour of the radial cross section of the inner tube 13 is circular, the inner contour of the radial cross section of the outer tube 14 is circular, and the inner tube 13 and the outer tube 14 can rotate relative to each other.

[0081] In this embodiment, the outer contour of the inner tube 13 is a cylinder, the inner through hole of the outer tube 14 is a circular hole, and there is a certain gap between the inner tube 13 and the outer tube 14 so that the inner tube 13 and the outer tube 14 can rotate relative to each other.

[0082] In an optional embodiment, the traction wire 5 passes through the interior of the inserter 2 and is connected to the single-wire structure 9 .

[0083] In this embodiment, the traction wire 5 is routed through the inner tube 13 of the inserter 2, and the suture 4 is routed outside the nail body 1 and the inserter 2, which can avoid the traction wire 5 and the suture 4 from being entangled.

[0084] The beneficial effects of the embodiments of the utility model are:

[0085] After the wire loop of the flexible self-locking knot shrinks, it can be hidden in the inner hole 6 where the nail body 1 contacts the wire knot, so that the overall length of the rigid anchor and the flexible wire knot is reduced, thereby truly shortening the depth of the pre-drilled hole in the bone channel 8, reducing bone loss, and facilitating patient recovery; at the same time, the wire loop is a fully enclosed structure, which completely binds the suture, and can be hidden in the end of the nail body 1 of the utility model after shrinking, so as to achieve the effect of completely fixing the suture; the traction line 5 is an independent and removable structure. After pulling the wire loop to make it self-locking, the traction line 5 can be directly pulled out without the need to cut the traction line 5, which reduces the operation time and reduces the operation cost; in addition, the moving stroke component of the inserter 2 is the outer tube 14, and the anchor implantation is completed by coordinating the tube diameter shape. During the implantation process, the wire loop contacts the inner tube 13 but does not move, and the wire loop will not be worn, reducing the risk of surgical failure.

[0086] 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 be subject to 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.
