Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an ankle arthroscopic surgical support. Background Technology

[0002] Ankle arthroscopy is a minimally invasive surgical technique used to diagnose and treat lesions within the ankle joint. During the procedure, the ankle joint cavity needs to be fully opened to allow for observation of the intra-articular structures and to clean, repair, or remove diseased tissue.

[0003] In ankle arthroscopic surgery, in order to fully open the ankle joint space and ensure surgical quality and convenience, auxiliary supports are often needed to fix and support the ankle. Current techniques for ankle arthroscopic surgery support can provide horizontal traction to the ankle, but their adjustment of the ankle's torsional angle is not ideal. Especially when dealing with lesions in different locations, the ankle may not be able to adjust to a suitable angle, resulting in insufficient opening of the ankle joint space, increasing the difficulty for the surgeon, and adversely affecting the surgical outcome.

[0004] Chinese patent CN215960912U discloses an ankle traction device, including a support rod, a clamping part, a traction rod, a first adjustment mechanism, and a second adjustment mechanism. One end of the support rod is movably engaged with the traction rod through the second adjustment mechanism, and the other end of the support rod is detachably connected to the clamping part. The second adjustment mechanism is provided with a support protrusion. One end of the first adjustment mechanism passes through the support protrusion and is movably engaged with the traction rod. The other end of the first adjustment mechanism is a free end. The first adjustment mechanism can achieve horizontal traction of the ankle, while the second adjustment mechanism can only achieve axial rotation of the ankle, i.e., rotation in a single plane, to adjust the ankle.

[0005] While the aforementioned device achieves horizontal traction and single-plane rotation adjustment of the ankle joint, it cannot adjust the multi-directional rotation angle. Furthermore, the device's complex structure requires careful attention to avoidance of the traction seat during ankle surgery, increasing the difficulty of the procedure. Since the ankle joint is a joint capable of free rotation within a certain range, the aforementioned device clearly cannot adequately meet the usage requirements. Further improvements are needed to achieve more reasonable rotation adjustment and treatment of foot and ankle joint lesions. Utility Model Content

[0006] The purpose of this invention is to provide an ankle arthroscopic surgical support that can conveniently adjust the ankle joint in multiple directions, increasing the convenience of diagnosis and treatment and reducing the difficulty of medical procedures.

[0007] To solve the above-mentioned technical problems, the embodiments of this utility model provide a technical solution as follows:

[0008] An ankle arthroscopic surgical support includes a sliding sleeve, on which a lifting rod is connected via a lifting seat. A traction rod is horizontally slidably connected to the distal end of the lifting rod. A ball joint structure is fixedly provided at one end of the traction rod, and a foot support for fixing the foot is detachably fixedly connected to the ball joint structure.

[0009] Furthermore, the ball joint structure includes a ball joint seat fixedly connected to the traction rod, and a ball joint rod with a ball head at one end. The ball joint seat is provided with a ball socket adapted to the ball head, and the ball head can be rotatably embedded in the ball socket.

[0010] Furthermore, a limiting member is threadedly connected to the ball joint seat, and a friction plate is provided at the end of the limiting member. By screwing the limiting member, the friction plate is driven to press against the ball head to lock the rotational degree of freedom of the ball joint rod.

[0011] Furthermore, the sliding sleeve is slidably mounted on the side rail of the operating table, and the sliding sleeve is provided with a first fastener. Tightening the first fastener can cause its end to press against the side rail to fix the position of the sliding sleeve.

[0012] Furthermore, the lifting rod includes a vertical rod that is slidably connected to the lifting seat and a horizontal rod that extends horizontally along the upper end of the vertical rod, and the traction rod is slidably connected to the end of the horizontal rod away from the vertical rod.

[0013] Furthermore, the lifting seat is fixedly installed on the outside of the sliding sleeve, the vertical rod passes through the lifting seat and slides vertically with it, and the lifting seat is provided with a second fastener. Tightening the second fastener can lock the lifting position of the vertical rod.

[0014] Furthermore, the end of the second fastener is provided with a wrench perpendicular to its axis, the wrench being used to manually adjust the tightening state of the second fastener.

[0015] Furthermore, a third fastener is provided on the horizontal bar. Tightening the third fastener can press the traction rod to fix its horizontal sliding position.

[0016] Furthermore, the end of the ball joint rod away from the ball head is provided with a groove, and the foot support can be detachably fixed in the groove by snap-fit ​​or fastener.

[0017] Furthermore, the footrest is equipped with a strap, one end of which is fixed to one side of the footrest, and the other end is fixed to the other side of the footrest via an adjustable connector.

[0018] The ankle arthroscopic surgical support provided by this utility model, compared with the prior art, can effectively achieve multi-directional rotational adjustment of the foot support through a traction rod that is horizontally slidably connected to the lifting rod and a ball joint structure fixed at one end of the traction rod. It can achieve adjustment of the ankle height and horizontal traction, and facilitate doctors to perform multi-directional rotational adjustment of the ankle joint during diagnosis and treatment, increasing the convenience of diagnosis and treatment, reducing the difficulty of medical treatment, and increasing the safety of ankle arthroscopic surgery. Through the limiting member that is threadedly connected to the ball joint seat and the friction plate that is set corresponding to the ball head, the limiting member is turned to drive the friction plate to press against the ball head, and the friction force is used to lock the rotational degree of freedom of the ball joint rod, so that the ball joint rod can be locked with the ball joint seat at any position within the adjustment range, fixing the position of the ankle, further increasing the stability and practicality of the ankle arthroscopic surgical support.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0026] like Figure 1-4 As shown, one embodiment of this utility model relates to an ankle arthroscopic surgical support, including a sliding sleeve 31. A lifting rod 32 is connected to the sliding sleeve 31 via a lifting seat 33. The sliding sleeve 31 is used for connection with the operating table 10. The lifting seat 33 is fixedly disposed on the outer side of the sliding sleeve 31. The proximal end of the lifting rod 32 is vertically disposed through the lifting seat 33 and can slide up and down and rotate relative to the sliding sleeve 31. A traction rod 34 is horizontally slidably connected to the distal end of the lifting rod 32. The traction rod 34 can be horizontally displaced in a direction perpendicular to the lifting rod 32. A ball joint structure is fixedly provided at one end of the traction rod 34. The ball joint structure is detachably fixedly connected to a foot support 38 for fixing the foot.

[0027] One embodiment relates to an ankle arthroscopic surgical support, wherein the ball joint structure includes a ball joint seat 35 and a ball joint rod 36 hinged together. The ball joint seat 35 is fixedly connected to a traction rod 34. One end of the ball joint rod 36 is provided with a ball head 361, and one end of the ball joint seat 35 is provided with a ball socket 351 adapted to the ball head 361. The ball head 361 is rotatably embedded in the ball socket 351 in multiple directions, so that the ball joint rod 36 can rotate freely relative to the ball joint seat 35 within a certain range. The end of the ball joint rod 36 away from the ball head 361 is provided with a groove 362, and the foot support 38 is disposed in the groove 362. The foot support 38 and the groove 362 are detachably fixedly connected. The detachable fixed connection can be by snap-fit ​​or by fastener connection to facilitate the removal and replacement of the foot support 38. The ball joint connection between the ball joint seat 35 and the ball joint rod 36 allows the foot 20, fixed within the footrest 38, to rotate with the footrest 38. This free rotation of the footrest 38 within a certain range allows for adaptation to the medical needs of the ankle joint, enabling doctors to adjust the ankle to a more suitable angle for treating the lesion, improving the quality and safety of the surgery and reducing its complexity. In an exemplary example, the footrest 38 is also equipped with a strap 381. One end of the strap 381 is fixedly connected to one side of the footrest 38, and the other end is fixed to the other side of the footrest 38 via an adjustable connector 382. The strap 381 is used to secure the foot 20 to the footrest 38, increasing medical safety. The adjustable connector 382 allows for adjustment of the length of the strap 381 wrapped around the foot to accommodate different sizes of feet 20 and the tightness requirements of the footrest.

[0028] like Figure 4 As shown, in one embodiment, an ankle arthroscopic surgical support is provided. To further increase the stability of the ankle arthroscopic surgical support during surgery, a limiting member 37 is provided corresponding to the ball joint 361 in the ball joint seat 35. The limiting member 37 is threadedly connected to the ball joint seat 35. A friction plate 371 is provided at one end of the limiting member 37 facing the ball joint rod 36. The ball socket 351 is provided with a relief hole corresponding to the friction plate 371. By screwing the limiting member 37, the friction plate 351 is driven to press against the ball joint 361 through the relief hole. The friction between the friction plate 351 and the ball joint 361 is used to restrict the rotation of the ball joint 361 relative to the ball joint seat 35, thereby locking the rotational degree of freedom of the ball joint rod 36. Preferably, the limiting member 37 is coaxially arranged with the ball joint seat 35, and the top of the limiting member 37 is arranged facing the bottom of the ball head 361. The friction plate 371 can abut against the ball head 361 under the drive of the limiting member 37, and limit the ball head 361 by friction, thereby preventing the ball joint rod 36 from rotating relative to the ball joint seat 35. When the ankle joint is adjusted to a suitable position, the fastening of the limiting member 37 ensures that the relative position of the ball joint rod 36 and the foot support 38 with the ball joint seat will not easily move due to external force, thereby increasing the stability and safety of the ankle arthroscopic surgery support.

[0029] One embodiment relates to an ankle arthroscopic surgical support. To increase the stability of the connection between the sliding sleeve 31 and the operating table 10, a side rail 11 is fixedly provided on the side of the operating table 10 in the horizontal direction. The sliding sleeve 31 is slidably sleeved on the side rail 11. The sliding sleeve 31 has an approximately U-shaped cross-section. A retaining edge 312 extends inward from the side wall of the sliding sleeve 31. The retaining edge 312 can engage with the edge of the side rail 11, blocking the relative displacement between the sliding sleeve 31 and the side rail 11 in the vertical direction along the side of the operating table 10. The stop limit prevents the sliding sleeve 31 from detaching from the side rail 11. The setting of the locking edge 312 and the side rail 11 further increases the stability of the ankle arthroscopic surgery support. The lower end of the sliding sleeve 31 is connected to a first fastener 311, which is threaded to the side wall of the sliding sleeve 31. By tightening the first fastener 311, one end of the first fastener 311 can press against the side rail 11 to fix the position of the sliding sleeve 31, thus fixing the sliding sleeve 31 to the side rail 11 and maintaining the stability of the sliding sleeve 31 relative to the operating table 10.

[0030] In one embodiment, an ankle arthroscopic surgical support is provided. To further enhance the practicality and convenience of the ankle arthroscopic surgical support, the lifting rod 32 is L-shaped, comprising a vertical rod 321 vertically slidably connected to the lifting seat 33 and a horizontal rod 322 extending horizontally along the top of the vertical rod 321. The vertical rod 321 can slide and rotate vertically relative to the sliding sleeve 31. A traction rod 34 is horizontally slidably connected to the end of the horizontal rod 322 away from the vertical rod 321. The lifting seat 33 is provided with a second fastener 331 corresponding to the vertical rod 321. The second fastener 331 is threadedly connected to the lifting seat 33. One end of the second fastener 331 faces the vertical rod 321. By tightening the second fastener 331, one end of the second fastener 331 can abut against the vertical rod 321 to lock the lifting position of the vertical rod 321, thus fixing the lifting rod 32 to the sliding sleeve 31.

[0031] In one embodiment, an ankle arthroscopic surgical support is provided. To improve the fastening effect of the second fastener 331 and increase the convenience of rotating the second fastener 331, a wrench 332 is provided at the end of the second fastener 331 away from the vertical rod 321. The wrench 332 is set perpendicular to the axial direction of the second fastener 331. The tightening state of the second fastener 331 can be manually adjusted by the wrench 332. Rotating the second fastener 331 by the wrench 332 can save the physical strength of medical personnel, is convenient to use, and can also increase the locking force of the second fastener 331 within the limited range of human power.

[0032] In one embodiment, an ankle arthroscopic surgical support is provided. The horizontal rod 322 is provided with a third fastener 341 corresponding to the traction rod 34. Tightening the third fastener 341 allows one end of the third fastener 341 to press against the traction rod 34 to fix its horizontal sliding position, thus fixing the horizontal rod 322 and the traction rod 34 in a fixed connection. When adjusting the horizontal position of the traction rod 34, the third fastener 341 can be loosened, and a force can be applied to it along the axial direction of the traction rod 34, causing the traction rod 34 to slide relative to the horizontal rod 322. This allows the front and rear positions of the footrest 38 to be adjusted in the horizontal direction. After the footrest 38 is adjusted to the correct position, the third fastener 341 is tightened to maintain the position of the footrest 38, stabilize the ankle position, and facilitate the surgery.

[0033] In use, the sliding sleeve 31 is snapped onto the side rail 11 of the operating table 10. The position of the sliding sleeve 31 is adjusted by sliding according to the approximate position of the patient and locked by the first fastener 311. The vertical height of the lifting rod 32 relative to the sliding sleeve 31 is adjusted according to the height that the ankle needs to be raised, that is, the height of the horizontal rod 322 of the lifting rod 32 relative to the operating table 10 is adjusted and locked by the second fastener 331. The ankle is pulled by adjusting the horizontal displacement of the traction rod 34. After adjustment, the traction rod 34 and the horizontal rod 322 are locked by the third fastener 341. The ball joint rod 36 is rotated in multiple directions to adjust the position of the foot support 38 so that the ankle joint is fully opened and the appropriate treatment angle is selected according to the location of the lesion and locked by the limiting member 37. By tightening the limiting member 37, the friction plate 371 is driven to abut against the ball head 361, which limits the relative movement of the ball joint rod 36 relative to the ball joint seat 35, ensuring the stability of the ankle arthroscopic surgery support for the ankle during the operation, effectively reducing the medical difficulty and increasing the safety of the operation.

[0034] This utility model provides an ankle arthroscopic surgical support. Through a traction rod that is horizontally slidably connected to a lifting rod and a ball joint structure fixed at one end of the traction rod, it can effectively achieve multi-directional rotational adjustment of the foot support, enabling adjustment of the ankle height and horizontal traction. It also facilitates multi-directional rotational adjustment of the ankle joint by doctors during diagnosis and treatment, increasing the convenience of diagnosis and treatment, reducing the difficulty of medical procedures, and increasing the safety of ankle arthroscopic surgery. Through a limiting member threadedly connected to the ball joint seat and a friction plate corresponding to the ball head, turning the limiting member drives the friction plate to press against the ball head, using friction to lock the rotational freedom of the ball joint rod. This allows the ball joint rod to lock with the ball joint seat at any position within the adjustment range, fixing the position of the ankle and further increasing the stability and practicality of the ankle arthroscopic surgical support.

[0035] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
