Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and more specifically, to an Achilles tendon fixation device and its method of use. Background Technology

[0002] For example, Chinese patent application number 201822021255.2 discloses a device for fixing the Achilles tendon with a tendon-skin splint, which assists in the recovery and fixation of the Achilles tendon by setting the tendon-skin splint.

[0003] For example, Chinese patent application number 201911213164.1 discloses a device for fixing the Achilles tendon skin and its usage method. Based on the above patent, it reduces the occurrence of pressure sores, sets up an observation window to observe the recovery of the Achilles tendon, and reduces the possibility of wire rope breakage.

[0004] In practical use, the Chinese patent with application number 201911213164.1 still has, but is not limited to, the following problems:

[0005] 1. The above patent only uses a flexible fixation part to reduce the possibility of pressure sores on the Achilles tendon skin. However, the recovery time of the Achilles tendon is usually more than ten or several weeks. The Achilles tendon fixation device is used directly for at least one month after the initial surgery. If the flexible fixation part is not replaced within one month, pressure sores will still occur. In addition, some flexible fixation parts will come into contact with tissue fluid secreted from the wound and medication left over from dressing changes. If they are not replaced in time, it will lead to complications such as infection.

[0006] 2: The aforementioned patent mainly utilizes two horizontally positioned steel wires to connect the ruptured Achilles tendon. The Achilles tendon is tensioned by pulling the two horizontally positioned steel wires. However, the horizontally positioned steel wires are not convenient in actual use. If the steel wires are positioned vertically with the lower leg, then the steel wires must pass through the surface of the tendon skin. Therefore, while tensioning the steel wires, the tendon skin will be pulled, leading to tendon skin damage. If the steel wires are used to suture under the tendon skin through the wound, then tensioning with steel wires will still lead to the problem of increasing the wound area. Summary of the Invention

[0007] The purpose of this invention is to provide an Achilles tendon fixation device and its usage method, which can easily and conveniently replace the flexible fixation component and can efficiently and accurately tension and fix the Achilles tendon.

[0008] The embodiments of the present invention are achieved through the following technical solution: an Achilles tendon fixation device, comprising at least one fixation group, the fixation group comprising two fixation members, each fixation member having a flexible fixation part and a rigid fixation part, the rigid fixation part comprising a first support rod, a first fixing rod, a connecting rod, a second fixing rod and a second support rod connected in sequence to each other, the first support rod and the second support rod being vertically arranged, the first fixing rod and the second fixing rod being detachably connected to the flexible fixation part, the ends of the two first support rods in each group being detachably connected by a first threaded rod, the ends of the two second support rods in each group being detachably connected by a second threaded rod, the fixation group also having a window, the window passing through the flexible fixation part and located between the first threaded rod and the second threaded rod.

[0009] Furthermore, the connecting rod in each fastener is positioned away from the flexible fastener.

[0010] Furthermore, the flexible fixing part includes a coating layer and a fixing layer, and the first fixing rod and the second fixing rod are detachably connected to the fixing layer.

[0011] Furthermore, the first threaded rod is provided with at least one through hole.

[0012] Furthermore, a limiting groove is provided at the end of the first support rod.

[0013] Furthermore, a medicated patch is also provided, which is placed inside the window.

[0014] A method of using an Achilles tendon fixation device includes the following steps:

[0015] S1: Treat the wound according to the Achilles tendon rupture and prepare for the procedure. Set one set of Achilles tendon fixation devices for one Achilles tendon rupture, three sets of Achilles tendon fixation devices for two Achilles tendon ruptures, and so on: the number of Achilles tendon fixation devices is equal to the number of Achilles tendon ruptures plus one.

[0016] S2: Connect the first end of the first medical wire rope to the upper end of the Achilles tendon rupture, and detachably connect the end of the first medical wire rope to the first threaded rod; connect the first end of the second medical wire rope to the upper end of the Achilles tendon rupture, and detachably connect the end of the second medical wire rope to the second threaded rod.

[0017] S3: Lay out the flexible fixing part and fix the rigid fixing part on the flexible fixing part;

[0018] S4: Tension the Achilles tendon by tightening the first and second threaded rods, and position the Achilles tendon healing site at the window.

[0019] S5: Check the installation effect of the Achilles tendon fixation device. After confirming that there are no errors, place the medicated patch inside the window.

[0020] S6: Wrap gauze around the garment as needed;

[0021] S7: Based on the recovery treatment time, remove the gauze and dressing, observe the Achilles tendon healing through the window, and replace the dressing.

[0022] S8: Remove the rigid fixation part from the flexible fixation part. The medical staff holds the rigid fixation part and cleans the contact surface of the flexible fixation part. After replacing the flexible fixation part, reinstall the new flexible fixation part and install the rigid fixation part on the new flexible fixation part. Adjust the tension of the first threaded rod and the second threaded rod, and reposition the dressing block and gauze.

[0023] S9: Repeat steps S7 and S8 until the Achilles tendon is fully recovered.

[0024] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0025] 1. The structure is simple and efficient, with multiple fixation groups. The fixation of several Achilles tendon ruptures is achieved through the cooperation of these multiple fixation groups.

[0026] 2. Both flexible and rigid fixation parts can be quickly and easily removed, facilitating postoperative Achilles tendon recovery, fundamentally solving the problem of pressure sores, and avoiding other complications.

[0042] Example

[0043] According to one aspect of this application, an Achilles tendon fixation device is provided.

[0044] Figure 1-4 According to some embodiments of this application, an Achilles tendon fixation device is provided, including a set of fixation groups 1, which includes two fixation members 10. Each fixation member 10 is provided with a flexible fixation part 11 and a rigid fixation part 12. The flexible fixation part 11 contacts the human tendon skin to improve comfort, and the rigid fixation part 12 fixes the steel wire rope to the tendon skin surface.

[0045] Specifically, such as Figure 2-4 As shown, the rigid fixing part 12 includes a first support rod 121, a first fixing rod 122, a connecting rod 123, a second fixing rod 124, and a second support rod 125 connected in sequence. The first support rod 121 and the second support rod 125 are vertically arranged to keep the end of the wire rope away from the surface of the tendon. The first fixing rod 122 and the second fixing rod 124 are both detachably connected to the flexible fixing part 11. Specifically, the detachable connection method is not fixed, including but not limited to one or more of the following: concealed buckle, Velcro, and nut and screw combination. The two first support rods 121 in each group are detachably connected at their ends via a first threaded rod 21, which connects to the upper Achilles tendon. The two second support rods 125 in each group are detachably connected at their ends via a second threaded rod 22, which connects to the lower Achilles tendon. The upper and lower Achilles tendons are tensioned by tightening the first threaded rod 21 and the second threaded rod 22. Specifically, the operation is as follows: the wire rope is tied tightly to the threaded rod, and the threaded rod is rotated to tighten the wire rope. After tightening, the nut is tightened. Figure 5-6As shown, in some embodiments, because the tension of the wire rope is relatively large, a polygonal groove is also provided at the end of the support rod to restrict the rotation of the threaded rod. Specifically, as shown in Figures 5-6, a polygonal prism-shaped groove such as a triangular prism or a quadrangular prism can be used. Correspondingly, a polygonal prism-shaped protrusion such as a triangular prism or a quadrangular prism should be provided at the end of the threaded rod. The rotation of the threaded rod is restricted by the concave-convex fit. In other embodiments, in order to quickly fix the wire rope to the threaded rod, two through holes 3 are drilled in the threaded rod, and the end of the wire rope is fixed by passing through the two through holes 3, which is quick and firm.

[0046] The fixation unit 1 is also provided with a window 2. The window 2 passes through the flexible fixation part 11 and is located between the first threaded rod 21 and the second threaded rod 22. The recovery of the Achilles tendon can be observed through the window 2. Of course, the window 2 can also be used in conjunction with a dressing block. The dressing block is placed in the window 2 and fixed by means of detachment or gauze, which facilitates the replacement of medication in a short period of time and stimulates muscle growth in the wound.

[0047] In some embodiments, the flexible fixing part 11 includes a dressing layer 111 and a fixing layer 112, and the first fixing rod 122 and the second fixing rod 124 are detachably connected to the fixing layer 112; similarly, the detachable connection method is not fixed, and the dressing layer 111 can be made of medical skin-friendly material.

[0048] This embodiment also includes a method of using an Achilles tendon fixation device, comprising the following steps:

[0049] S1: Treat the wound according to the Achilles tendon rupture and prepare for the procedure. Set one set of Achilles tendon fixation devices for one Achilles tendon rupture site, three sets of Achilles tendon fixation devices for two Achilles tendon rupture sites, and so on. The number of Achilles tendon rupture devices is equal to the number of Achilles tendon rupture sites plus one. In this embodiment, one set is sufficient.

[0050] S2: Connect the first end of the first medical wire rope to the upper end of the Achilles tendon rupture, and detachably connect the end of the first medical wire rope to the first threaded rod 21; connect the first end of the second medical wire rope to the upper end of the Achilles tendon rupture, and detachably connect the end of the second medical wire rope to the second threaded rod 22.

[0051] S3: Lay out the flexible fixing part 11 and fix the rigid fixing part 12 on the flexible fixing part 11;

[0052] S4: The Achilles tendon is tensioned by tightening the first threaded rod 21 and the second threaded rod 22, and the healing site of the Achilles tendon is set at the window 2;

[0053] S5: Check the installation effect of the Achilles tendon fixation device. After confirming that there are no errors, place the medicated patch in the window 2.

[0054] S6: Wrap gauze around the garment as needed;

[0055] S7: Based on the recovery treatment time, remove the gauze and medicated patch, observe the Achilles tendon healing through window 2, and replace the medicated patch;

[0056] S8: Remove the rigid fixation part 12 from the flexible fixation part 11. The medical staff holds the rigid fixation part 12 and cleans the contact surface of the flexible fixation part 11. After replacing the flexible fixation part 11, reinstall the new flexible fixation part 11 and install the rigid fixation part 12 on the new flexible fixation part 11. Adjust the tension of the first threaded rod 21 and the second threaded rod 22, and reposition the dressing block and gauze.

[0057] S9: Repeat steps S7 and S8 until the Achilles tendon is fully recovered.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art.
