Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a non-invasive ankle traction device. Background Technology

[0002] The ankle joint is a vital weight-bearing joint with a complex anatomy and crucial function. Surgery is often an effective intervention for treating ankle-related diseases or injuries. To ensure successful surgery, appropriate traction force is provided intraoperatively using a traction device to open the joint space and facilitate surgical manipulation. However, existing ankle traction devices are inconvenient to fix and adjust. After adjustment, they are often fixed by tightening knobs, resulting in poor stability. During traction, loosening or displacement may lead to ineffective traction or even secondary injury to the patient. Furthermore, adjusting the support spacing and traction force of most devices is complex, consuming time and effort for medical staff and hindering surgical efficiency. In addition, the support and fixation methods of existing devices can easily compress the patient's limb, potentially causing discomfort or even pressure sores with prolonged use, which is detrimental to postoperative recovery. Therefore, a non-invasive ankle traction device is needed to address these issues. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 An ankle non-invasive traction device includes a first guide rail 1 and a second guide rail 101. Both the first guide rail 1 and the second guide rail 101 are provided with an L-shaped fixing plate 2 at one end close to each other. The two L-shaped fixing plates 2 are rotatably connected at one end close to each other by a connecting shaft. Both the first guide rail 1 and the second guide rail 101 are provided with sliding seats 3. Both sliding seats 3 are provided with adjustable brackets on the front. An ankle traction device is provided at the upper end of the adjustable bracket installed on the second guide rail 101.

[0024] The ankle traction device includes a traction component 6 and a fixation strap component 7, with the fixation strap component 7 located at the front end of the traction component 6.

[0025] The slide 3 has a convex plate on one side of its front wall, and a positioning pin 301 is provided on the convex plate. Several positioning holes 102 that cooperate with the positioning pin 301 are equally spaced on the first guide rail 1 and the second guide rail 101. The outer surface of the positioning pin 301 near its knob end has an external thread. The positioning pin 301 is threaded to the slide 3 through the external thread. By turning the knob to remove the positioning pin 301, the slide 3 slides along the first guide rail 1 or the second guide rail 101, which can effectively adjust the distance between the two adjustable supports. After the position of the adjustable supports is adjusted, the positioning pin 301 is reinstalled and passes through the positioning hole 102, which effectively ensures the stability of the slide 3, adapts to patients of different sizes, and avoids the slide 3 sliding during surgery, thus avoiding secondary trauma to the patient.

[0026] The adjustable support includes a protruding column 4 and an L-shaped support rod 5. The protruding column 4 is fixedly connected to the slide 3. A threaded groove is opened in the protruding column 4, and a pressing column 401 is threadedly connected to the protruding column 4 through the threaded groove. A handle 402 is provided on the front of the pressing column 401. A through hole 403 is opened in the center of the protruding column 4. The lower end of the L-shaped support rod 5 extends to the outside through the through hole 403. A support soft sleeve 501 is sleeved on the outer surface of the crossbar of the L-shaped support rod 5 installed on the first guide rail 1. The through hole 403 facilitates the installation of the L-shaped support rod 5 and makes the height of the L-shaped support rod 5 adjustable. After the height of the L-shaped support rod 5 is adjusted, the pressing column 401 is retracted inward and pressed against the L-shaped support rod 5 by rotating the handle 402, so as to ensure that the position of the L-shaped support rod 5 is fixed. The support soft sleeve 501 can effectively support the patient's knee joint and ensure the patient's comfort.

[0027] The traction component 6 includes a top sleeve 601, a fixing block 602, and a threaded rod 603. The top sleeve 601 is fitted onto the outer surface of the upper crossbar of the L-shaped support rod 5. The fixing block 602 is fixedly installed on the lower surface of the top sleeve 601. The threaded rod 603 is threadedly connected to the fixing block 602. One end of the threaded rod 603 is connected to a connecting ring 604 via a connecting block. A crank 605 is provided at the end of the threaded rod 603 away from the connecting ring 604. By turning the crank 605, the threaded rod 603 can be effectively driven to rotate synchronously and move horizontally to the right. During the horizontal movement of the threaded rod 603 to the right, the connecting ring 604 can exert a rightward pulling force on the fixing band component 7, thereby achieving traction on the patient's ankle joint.

[0028] The fixing strap assembly 7 includes a buckle 701, a heel drag 702, and a strap 703. The buckle 701 is located between the connecting ring 604 and the heel drag 702. There are two straps 703, which are respectively located on both sides of the heel drag 702. The two straps 703 are provided with Velcro 704 that are mutually adhesive. By providing the heel drag 702, the patient's heel can be effectively lifted. Then, the two straps 703 are mutually adhesive through the Velcro 704. The straps 703 are tied to the instep of the patient, which can effectively fix the patient's foot and ensure stability.

[0029] Among them, the first guide rail 1 and the second guide rail 101 are both fixedly provided with mounting blocks 201 at their opposite ends. The L-shaped fixing plate 2 and the mounting block 201 are both provided with fixing holes 202. By providing fixing holes 202, it is easy to install and fix the first guide rail 1 and the second guide rail 101. Since the two L-shaped fixing plates 2 are connected by a connecting shaft at their opposite ends, the first guide rail 1 and the second guide rail 101 can rotate. This can be adapted to use in folding and angle-adjustable hospital beds, and has a wide range of applications.

[0030] Working principle: By rotating the knob to remove the positioning pin 301, the slide 3 slides along the first guide rail 1 or the second guide rail 101, which can effectively adjust the distance between the two adjustable supports. After the position of the adjustable support is adjusted, the positioning pin 301 is reinstalled and passes through the positioning hole 102, which effectively ensures the stability of the slide 3, adapts to patients of different body sizes, and avoids the slide 3 sliding during surgery, thus avoiding secondary trauma to the patient.

[0031] Furthermore, the support sleeve 501 effectively supports the patient's knee joint and ensures patient comfort. The heel strap 702 effectively lifts the patient's heel. The two straps 703 are then glued together by Velcro 704 and tied to the instep of the patient, effectively fixing the patient's foot and ensuring stability. By turning the crank handle 605, the threaded rod 603 can be driven to rotate synchronously and move horizontally to the right. During the horizontal movement of the threaded rod 603 to the right, the connecting ring 604 exerts a rightward pulling force on the fixing strap assembly 7, thereby achieving traction on the patient's ankle joint.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
