Description

Technical Field

[0001] This utility model relates to the field of Achilles tendon suturing technology, and in particular to a fixation device for Achilles tendon suturing. Background Technology

[0002] An Achilles tendon rupture is a complete tear of the Achilles tendon caused by direct or indirect force. Symptoms include local swelling and pain in the posterior ankle, weakness in plantar flexion, and inability to stand on tiptoe. Treatment for Achilles tendon rupture generally involves suturing the ruptured tendon together. During the suturing process, two straight clamps are needed to hold the broken ends, overlap them, and then suture them. However, the straight clamps are held by the surgical assistant, and when they are held at both ends, the angle is obvious and they are easy to loosen, which increases the difficulty of the operation and reduces the efficiency of the operation.

[0003] For example, patent CN218515798U discloses a fixation device for Achilles tendon rupture suturing, including a left slide rail and a right slide rail. The upper and lower ends of the left and right slide rails are connected by an upper arc-shaped bracket and a lower arc-shaped bracket, respectively. A first lower steel plate and a second lower steel plate are spaced apart between the left and right slide rails, and both ends of the first and second lower steel plates are slidably connected to the left and right slide rails, respectively. This aforementioned fixation device for Achilles tendon rupture suturing has shortcomings. Although it achieves fixation at the Achilles tendon rupture site, it has limitations. Fixing the two lower steel plates to the two slide rails, as well as fixing the two sets of lower steel plates to the upper steel plate, requires medical personnel to rotate a large number of bolts for connection, increasing the complexity of the operation, prolonging the operation time, and reducing the efficiency of the surgery.

[0004] Therefore, in order to solve this problem, we propose a fixation device for Achilles tendon suturing. Utility Model Content

[0007] Preferably, the first and second slide rails are each provided with a plurality of slots evenly distributed on their sidewalls, the connecting plate is provided with a third mounting groove on its sidewall, and a through hole is provided on the sidewall of the connecting plate, the through hole communicating with the third mounting groove. The fixing component includes a mounting plate, which is slidably connected to the inner wall of the third mounting groove. A pull block is fixedly connected to the sidewall of the mounting plate, and a locking post is fixedly connected to the sidewall of the mounting plate away from the pull block. The locking post is slidably connected to the inner wall of the through hole. A first spring is provided at both the upper and lower ends of the pull block, and the two ends of the first spring are fixedly connected to the inner wall of the third mounting groove and the sidewall of the connecting plate, respectively.

[0008] Preferably, the upper ends of the first and second slide rails are provided with toothed grooves, and the lower end of the lower steel plate is fixedly connected with a locking tooth, which engages with the toothed groove.

Two second mounting slots 133 are provided on the inner side wall. The upper end of the lower steel plate 13 is rotatably connected to the upper steel plate 16 via a hinge. The lower end of the upper steel plate 16 is provided with an upper tooth 161. One end of the upper surface of the upper steel plate 16 is provided with a through slot 162. The inner wall of the through slot 162 is fixedly connected to a limit post 163. Two push plates 164 are slidably connected to the side wall of the limit post 163. A locking block 165 is fixedly connected to the side wall of the lower end of the push plate 164. A second spring 166 is movably sleeved on the side wall of the limit post 163. The two ends of the second spring 166 are fixedly connected to the push plate 164 respectively.

[0024] When using this device, place it on the Achilles tendon rupture site in the heel. The first slide rail 1 and the second slide rail 12 are located on the left and right sides of the heel, respectively. Then, raise the two upper steel plates 16 and press the upper and lower ends of the Achilles tendon rupture onto the lower teeth 131 on the two lower steel plates 13. Leave some suture space at the ends of the two ruptured ends of the Achilles tendon that are close to each other. Then, press the upper steel plates 16 down onto the upper ones, with the upper teeth 161 and lower teeth 131 interlacing to compress the Achilles tendon. At this time, the locking block 165 at the lower end of the push plate 164 slides directly into the first mounting groove 132 and engages with the second mounting groove 133. This eliminates the need for medical personnel to frequently turn the screws for fixation, resulting in high operational efficiency.

[0025] The first slide rail 1 and the second slide rail 12 are each provided with a plurality of slots 101 evenly distributed on their side walls. The connecting plate 14 is provided with a third mounting groove 141 on its side wall. The connecting plate 14 is also provided with a through hole 142 on its side wall, which communicates with the third mounting groove 141. The fixing assembly 15 includes a mounting plate 151, which is slidably connected to the inner wall of the third mounting groove 141. A pull block 152 is fixedly connected to the side wall of the mounting plate 151. The side wall of the mounting plate 151 away from the pull block 152 is fixedly connected to... There is a locking post 153, which is slidably connected to the inner wall of the through hole 142. The upper and lower ends of the pull block 152 are provided with first springs 154. The two ends of the first springs 154 are fixedly connected to the inner wall of the third mounting groove 141 and the side wall of the connecting plate 14, respectively. The locking post 153 is used to engage with the locking groove 101 at the end away from the pull block 152 to limit the lower steel plate 13. The locking can be achieved by directly pulling the pull block 152, without the need to frequently turn the screws, making the operation simple.

[0026] The upper ends of the first slide rail 1 and the second slide rail 12 are both provided with toothed grooves 102. The lower end of the lower steel plate 13 is fixedly connected with a locking tooth 134. The locking tooth 134 engages with the toothed groove 102 and is used to perform secondary positioning of the lower steel plate 13 by engaging with the toothed groove 102.

[0027] The inner wall of the through groove 162 is provided with a sliding groove 1621. The side wall of the push plate 164 is fixedly connected to a limiting block 1641. The limiting block 1641 is slidably connected to the inner wall of the sliding groove 1621. The limiting block 1641 is used to limit the push plate 164 and increase the stability of movement.

[0028] The end of the locking post 153 away from the pull block 152 is semi-circular, which is used for quick engagement between the end of the locking post 153 away from the pull block 152 and the slot 101, increasing smoothness and reducing jamming.

[0029] Latex plates 17 are fixedly connected to the lower ends of both the first slide rail 1 and the second slide rail 12. These plates increase friction and reduce slippage when the first slide rail 1 and the second slide rail 12 are in contact with the skin. They also help reduce pressure on the skin and increase comfort.

The lower steel plate 13 and the upper steel plate 16 are both 7mm wide and 3mm high. When using the device, place it on the Achilles tendon rupture site in the heel, with the first slide rail 1 and the second slide rail 12 located on the left and right sides of the heel, respectively. Then, pull the pull block 152 directly to release the engagement between the end of the locking post 153 away from the pull block 152 and the locking groove 101. Then, move the lower steel plate 13 to the appropriate position and release the pull block 152, so that the end of the locking post 153 away from the pull block 152 engages with the locking groove. 101 Re-engages the connection, thereby limiting the lower steel plate 13. Then, raise the two upper steel plates 16 respectively, pressing the upper and lower ends of the Achilles tendon rupture onto the lower teeth 131 on the two lower steel plates 13 respectively, and leaving some suture space at the ends of the two ruptured ends of the Achilles tendon that are close to each other. Then, press the upper steel plate 16 down onto the upper one, with the upper teeth 161 and lower teeth 131 interlacing to compress the Achilles tendon. At this time, the locking block 165 at the lower end of the push plate 164 slides directly into the first mounting groove 132 and engages with the second mounting groove 133, eliminating the need for medical personnel to frequently rotate the screws for fixation.
