Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a knee joint suspension disinfection device. Background Technology

[0002] In orthopedics, especially in complex surgeries such as joint replacement, preoperative leg disinfection is crucial for preventing postoperative infection. For patients about to undergo knee replacement surgery, thorough disinfection of the entire area from the thigh to the foot is necessary before surgery, which requires a stable and appropriate leg elevation technique.

[0003] Currently, traditional disinfection procedures typically rely on doctors manually lifting the patient's legs (such as...). Figure 12 As shown in the diagram, this method ensures comprehensive disinfection coverage. However, it has significant limitations. First, for obese patients or those with muscular legs, prolonged manual lifting can easily lead to exhaustion for medical staff, increasing fatigue and the risk of accidental leg slippage, potentially causing leg injury. Second, to ensure thorough and even disinfection of every area of ​​the leg, frequent adjustments to the height, angle, and position of the leg lift are necessary. This continuous adjustment further increases the physical burden on medical staff, exacerbating fatigue, and significantly reduces the stability and controllability of the entire disinfection process. Furthermore, during prolonged lifting and adjustment, the muscles in the doctor's arms, back, and legs remain tense, leading to decreased precision in hand movements and potentially resulting in insufficient or excessive lifting, thus affecting disinfection effectiveness, leaving potential blind spots, and increasing the risk of infection. Simultaneously, manual adjustment often lacks precise control, especially for disinfection at specific angles or positions, making it difficult to guarantee thorough disinfection.

[0004] Therefore, how to design a knee joint suspension disinfection device that can effectively support and move the patient's legs while ensuring the safety and convenience of the disinfection process is a technical problem that has not yet been solved in the existing technology.

[0066] This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0067] This embodiment provides a device for suspending and disinfecting the knee joint, such as... Figure 1-11As shown, the device includes: a fixed base 1, a rotating base 2, a slide rail 3, a movable support 5, and a lifting member 7; wherein, the fixed base 1 is suitable for detachable installation on the operating table; the rotating base 2 is rotatably installed on the fixed base 1 via an installation structure; one end of the slide rail 3 is fixedly connected to the rotating base 2 and can rotate with the rotating base 2 in a vertical plane; a limiting component is provided between the fixed base 1 and the slide rail 3 for limiting and fixing the slide rail 3 relative to the fixed base 1; the movable support 5 includes a support arm 52 and a sliding sleeve 50 disposed at one end of the support arm 52; the sliding sleeve 50 is detachably mounted on the slide rail 3, and a locking mechanism is provided between the sliding sleeve 50 and the slide rail 3 for locking the sliding sleeve 50 at a selected position on the slide rail 3 at any time; the lifting member 7 is rotatably installed on the other end of the support arm 52 via a rotating structure, and the top surface of the lifting member 7 has an arc-shaped lifting surface.

[0068] When using the knee joint suspension disinfection device of this embodiment, firstly, the fixing seat 1 is fitted onto the connecting slide plate of the operating table and moved to a suitable position for the patient's affected limb at the side of the operating table and fixed. Next, the angle of the slide rail 3 is manually adjusted so that it is vertical relative to the fixing seat 1. After adjustment, the position of the slide rail 3 is locked using the limiting component. Then, the movable bracket 5 is lowered to the bottom along the slide rail 3 so that the support arm 52 naturally rests on the side of the patient's leg. The lifting member 7 is adjusted to an angle suitable for the patient's comfort by rotating the structure. Subsequently, the patient's leg is placed on the arc-shaped lifting surface to ensure that the patient's knee joint is properly supported.

When it is necessary to store the device, first move the entire device to the head (or foot) of the operating table, and then raise the moving support 5 a certain distance to avoid interference with the head (or foot) of the operating table. Next, release the locking component from the slide rail 3, and push the slide rail 3 and the rotating seat 2 to rotate a certain angle to the outside of the operating table so that it, along with the moving support 5, rotates and folds into the bottom of the operating table for storage, so that it can be used later.

[0069] The knee joint suspension disinfection device in this embodiment effectively reduces the physical exertion and fatigue of medical staff through stable mechanical support and convenient height adjustment, improves the stability and safety of operation, simplifies the disinfection process and storage procedures, and improves disinfection efficiency.

[0070] like Figure 1 and Figure 2 As shown, the fixing seat 1 is provided with a connecting groove 11 extending through both ends along the axial direction. The side wall of the fixing seat 1 facing the operating table is provided with a transverse opening 111 communicating with the connecting groove 11. The transverse opening 111 is used to guide the fixing seat 1 to be sleeved on the operating table connecting slide plate. The bottom of the fixing seat 1 is provided with a first threaded through hole 12 communicating with the connecting groove 11. It also includes a positioning handle 8 with a threaded post 81 at the top. The threaded post 81 is screwed to the first threaded through hole 12, passes through the bottom side wall of the fixing seat 1, and is then pressed and fixed against the operating table connecting slide plate.

[0071] like Figure 6 and Figure 8 As shown, the mounting structure includes: an arc-shaped sliding groove 15, threaded blind holes 21, and bolts 9; wherein there are two arc-shaped sliding grooves 15, which are concentrically arranged on the side wall of the fixed seat 1 away from the operating table; the arc-shaped sliding grooves 15 have a stepped countersunk hole structure along the axial direction of the fixed seat 1, with the larger diameter section of the stepped countersunk hole structure facing inward and the smaller diameter section facing outward, forming a limiting step surface between them; there are two threaded blind holes 21, which are arranged on the side wall of the rotating seat 2 facing the fixed seat 1, and correspond to the two arc-shaped sliding grooves 15 respectively; there are two bolts 9, the screw part can pass through the two arc-shaped sliding grooves 15 respectively and be screwed and fixed to the two threaded blind holes 21; the screw head is located in the larger diameter section and is axially limited by the limiting step surface; the two bolts 9 can slide in the two arc-shaped sliding grooves 15 respectively to drive the rotating seat 2 to rotate within a certain range. It also includes a circular notch 13, which is formed on the fixed base 1, specifically located on the side wall of the opening side of the connecting groove 11. The circular notch 13 is designed on the side wall of the fixed base 1, which facilitates the processing of the arc-shaped sliding groove 15 and the accurate installation of the bolts 9, thereby improving the assembly efficiency and stability of the overall structure.

[0072] like Figure 5 and Figure 6 As shown, the rotating seat 2 has a mounting groove 22 on its side wall facing the fixed seat 1, and one end of the mounting groove 22 has a vertical opening 23; one end of the slide rail 3 is inserted into the mounting groove 22 through the vertical opening 23; the fixed seat 1 has a first central hole 17 on its side wall away from the operating table, and the first central hole 17 is concentrically arranged with the arc-shaped sliding groove 15; the slide rail 3 has a second central hole 31 on its side opposite to the fixed seat 1, which is opposite to the first central hole 17; it also includes a rotating shaft 10, which can be rotatably inserted into the first central hole 17 and the second central hole 31.

[0073] like Figure 5 and Figure 6As shown, the axial depth of the mounting groove 22 is greater than the thickness of the slide rail 3. The limiting assembly includes: a first limiting groove 18, a second limiting groove 32, a limiting post 102, a mounting cavity 101, a spring 19, a second threaded through hole 24, and a second locking bolt 25. There are two first limiting grooves 18, formed on the side wall of the fixed seat 1 away from the operating table. The two first limiting grooves 18 are symmetrical with respect to the first central hole 17 and communicate with the first central hole 17, which is a blind hole. There are two second limiting grooves 32, formed... On the side of the slide rail 3 opposite to the fixed seat 1, two second limiting grooves 32 are symmetrical with respect to the second central hole 31 and communicate with the second central hole 31; the two first limiting grooves 18 and the two second limiting grooves 32 can be spliced ​​together to form two limiting cavities; there are two limiting posts 102, symmetrically arranged on the outer peripheral wall of the rotating shaft 10; the mounting cavity 101 is disposed in the rotating shaft 10, and has an end opening at one end facing the first central hole 17; the spring 19 is pressed and installed in the mounting cavity 101, with its two ends separated. Do not abut against the bottom of the first central hole 17 and the bottom of the mounting cavity 101; in the initial state, the spring 19 pushes the slide rail 3 away from the fixed seat 1 by a certain distance, so that the limiting post 102 is always engaged in the second limiting groove 32 and separated from the first limiting groove 18. At this time, rotating the slide rail 3 can synchronously drive the rotating seat 2 to rotate relative to the fixed seat 1; the second threaded through hole 24 is opened on the side wall of the rotating seat 2 away from the fixed seat 1 and communicates with the mounting groove 22; the second locking bolt 25, Screwed into the second threaded through hole 24, it can pass through the side wall of the rotating seat 2 and enter the mounting groove 22; it is used to screw inward when the two limiting posts 102 are aligned with the two first limiting grooves 18 and the two second limiting grooves 32 respectively, so as to push the slide rail 3 close to the fixed seat 1, thereby limiting the two limiting posts 102 in the two limiting cavities formed by the splicing of the two first limiting grooves 18 and the two second limiting grooves 32. At this time, the slide rail 3 is locked and cannot drive the rotating seat 2 to rotate relative to the fixed seat 1.

[0074] When the two limiting posts 102 are aligned with the two first limiting grooves 18 and the two second limiting grooves 32 respectively, the second locking bolt 25 is screwed inward, so that the second locking bolt 25 applies a pushing force to the slide rail 3, forcing the slide rail 3 to move towards the fixed seat 1, and pushing the rotating shaft 10 to move towards the fixed seat 1, and further compressing the spring 19, until the two limiting posts 102 are limited in the two limiting cavities formed by the splicing of the two first limiting grooves 18 and the two second limiting grooves 32, thereby locking the slide rail 3 to the fixed seat 1; when the second locking bolt 25 is turned outward, the spring 19 restores its deformation and pushes the rotating shaft 10 to move the slide rail 3 away from the fixed seat 1, until the first limiting groove 18 and the second limiting groove 32 separate, the limiting post 102 disengages from the first limiting groove 18, and thus unlocks the slide rail 3 from the fixed seat 1.

[0075] like Figure 7 As shown, the locking mechanism includes: a ratchet 4, a handle 51, and a grip 6; wherein, the ratchet 4 is disposed on one side of the slide rail 3 along its length; the handle 51 is disposed on the slide sleeve 50 and has an inner cavity 511 inside, the inner cavity 511 having an outlet 522 facing the ratchet 4; the grip 6 is rotatably mounted in the inner cavity 511, and has a pawl 61 at one end, and a limiting structure is provided between the grip 6 and the handle 51; the pawl 61 has a first state of extending through the outlet 522 and engaging with the ratchet 4, and a second state of retracting from the outlet 522 and disengaging from the ratchet 4; preferably, the limiting structure includes a first top surface 62 disposed at one end of the grip 6 and a second top surface 523 of the inner cavity 511 opposite to it.

[0076] In this embodiment, one end of the grip 6 with a pawl 61 is rotatably connected to the inner wall of the inner cavity 511 via a pivot 64. When the grip 6 rotates around the pivot 64, it can drive the pawl 61 to extend out of or retract into the inner cavity 511. When the pawl 61 engages with the ratchet 4, the first top surface 62 of one end of the grip 6 and the second top surface 523 of the inner cavity 511 are mutually abutted to prevent the pawl 61 and the ratchet 4 from disengaging.

[0077] A tension spring 63 is provided between the grip bar 6 and the handle 51. In the initial state, the pawl 61 extends out of the inner cavity 511 at a certain angle under the action of the tension spring 63.

[0078] In this embodiment, the tension spring 63 can be disposed between the top of the grip 6 and the top inner wall of the inner cavity 511, and applies a pushing force to the grip 6, so that the pawl 61 tends to always extend out of the inner cavity 511.

[0079] like Figure 7As shown, the ratchet teeth of the ratchet bar 4 are inclined upwards, with a limiting plane located above and a guide slope located below; when the grip bar 6 is pulled directly upwards, the pawl 61 slides with the guide slope, and under the action of the tension spring 63, the pawl 61 always abuts against the guide slope; after the external force disappears, the pawl 61 abuts against the limiting plane and is limited, and under the action of the limiting structure, the pawl 61 always abuts against the limiting plane.

[0080] like Figure 10 and Figure 11 As shown, the rotating structure includes: a support body 73, a rotating spherical part 72, and a sealing cap 74; wherein, the support body 73 is fixedly disposed at the end of the support arm 52, and has a spherical cavity 731 and a sealing cap 74 inside; wherein, the rotating spherical part 72 includes a spherical head 721 and a connecting rod 722 fixedly connected to the spherical head 721; the spherical head 721 is rotatably mounted in the spherical cavity 731; the sealing cap 74 is assembled on the support body 73 to limit the spherical head 721 in the spherical cavity 731; the sealing cap 74 has an upper through hole 741, and the connecting rod 722 passes through the upper through hole 741 and connects to the bottom of the lifting member 7; preferably, the top end of the connecting rod 722 has an external thread section 723; the bottom of the lifting member 7 has a corresponding internal thread hole 76, and the connecting rod 722 is threadedly connected to the lifting member 7. The external threaded section 723 is screwed into the internal threaded hole 76. The combination of the support body 73, the rotating ball part 72 and the closing cap 74 enables the lifting member 7 to rotate flexibly on the support arm 52. This design allows the lifting member 7 to be adjusted according to the patient's comfort, improving the convenience and comfort of use.

[0081] like Figure 9 and Figure 10 As shown, a locking and fixing structure is also included to lock and fix the spherical head 721. The locking and fixing structure includes a screw hole channel 732 and a locking screw 75. The screw hole channel 732 is located at the bottom of the support body 73 and communicates with the spherical cavity 731. The locking screw 75 is threadedly connected to the screw hole channel 732, allowing it to enter the spherical cavity 731 and press and fix the spherical head 721. The combination of the screw hole channel 732 and the locking screw 75 achieves the locking and fixing of the spherical head 721 within the spherical cavity 731. This design ensures the stability of the support member 7 after angle adjustment and prevents accidental rotation during use.

[0082] like Figure 10 and Figure 11As shown, the top surface of the support member 7 has an arc-shaped support surface, on which a silicone pad 71 is provided. The arc-shaped support surface matches the shape of the patient's leg, providing better support and comfort, while the addition of the silicone pad 71 further improves the softness and anti-slip performance of the support surface, ensuring the patient's safety and comfort during the disinfection process.

[0083] The knee joint suspension disinfection device in this embodiment is used in the following way:

[0084] First, the fixing seat 1 is fitted onto the connecting slide plate of the operating table, guided by the transverse opening 111, ensuring that the connecting groove 11 is fully engaged with the slide plate. After moving the fixing seat 1 to a suitable position for the patient's affected limb, the threaded post 81 of the positioning handle 8 is screwed into the first threaded through hole 12, so that it is pressed against the operating table slide plate, completing the stable installation of the fixing seat 1. Next, the angle of the slide rail 3 is manually adjusted so that it is vertical relative to the fixing seat 1. After adjustment, the second locking bolt 25 is tightened, pushing the vertically positioned slide rail 3 close to the circular boss 16, thereby compressing the spring 19 in the mounting cavity 101, causing the rotating shaft 10 to move into the first central hole 17, and the limiting post 102 is locked between the first limiting groove 18 and the second limiting groove 32, fixing the slide rail 3 vertically onto the fixing seat 1. Then, the moving bracket 5 is lowered to the bottom along the slide rail 3, so that the support arm 52 naturally rests on the side of the patient's leg. When adjusting the height, rotate the handle 6 to retract the pawl 61 from the outlet 522 and disengage it from the ratchet 4. Then, the moving bracket 5 can be adjusted upwards or downwards. After adjustment, release the handle 6. Under the action of the tension spring, the pawl 61 extends through the outlet 522 and engages with the ratchet 4. Rotate the lifting component 7 to a comfortable angle for the patient. The spherical head 721 rotates flexibly within the spherical cavity 731. After adjustment, screw the locking screw 75 into the screw hole channel 732 to press the spherical head 721 and fix the angle. When the patient's leg is placed, ensure that the knee joint is fully in contact with the arc-shaped lifting surface covered by the silicone pad 71 to ensure proper support for the patient's knee joint. According to the patient's body shape, fine-tune the height of the sliding sleeve 50 again to lift and support the patient's knee joint to a position that is convenient for medical staff to perform disinfection operations. The locking mechanism keeps the sliding sleeve 50 stable throughout the process, preventing movement during disinfection. After disinfection, the locking mechanism is released from the sliding sleeve 50, and the height of the moving bracket 5 is slowly adjusted so that the support arm 52 is lowered to a suitable height. Then, the patient's legs are removed from the arc-shaped support surface. When the device needs to be stored, the entire device is first moved to the head (or foot) of the operating table, and then the moving bracket 5 is raised a certain distance to avoid interference with the head (or foot) of the operating table. Next, the second locking bolt 25 is turned outward, and the elastic force of the spring 19 is released, pushing the rotating shaft 10. The rotating shaft pushes the slide rail 3 to move outward, and at the same time, the limiting post 102 disengages from the first limiting groove 18, releasing the fixation of the vertical sliding rail 3. The slide rail 3 and the rotating seat 2 are pushed to rotate a certain angle to the outside of the operating table, so that it, along with the moving bracket 5, rotates and folds into the bottom of the operating table for storage, so that it can be used later.

[0085] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
