Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a postoperative anti-dislocation leg-splitting seat cushion. Background Technology

[0002] Hip replacement surgery, also known as artificial hip replacement, involves inserting an artificial prosthesis, comprising the femur and acetabulum, into healthy bone using bone cement and screws to replace the diseased joint and restore normal hip function. After surgery, the affected limb is placed in an outward tilt position, with the replaced hip joint abducted at approximately 15°. The legs are then positioned to maintain both hip joints in an abducted, neutral position to prevent flexion, adduction, or internal rotation. Currently, trapezoidal pillows are often used after hip replacement surgery to position the angle between the legs and help patients maintain a correct postoperative recovery posture. However, this method is extremely inconvenient when the patient is sitting, hindering rapid recovery.

[0003] In existing technologies, after hip replacement surgery, patients need to maintain the affected limb in an abducted neutral position to avoid dislocation caused by adduction and internal rotation. However, if the cushion does not have a leg-splitting function, the patient's legs may be restricted to a close distance, which may increase the risk of adduction and internal rotation of the affected limb, thereby increasing the risk of dislocation. Simultaneously, clinical practice has also found that patients undergoing hip replacement surgery often experience balance disorders due to decreased tolerance, reduced muscle elasticity and fiber aggregation, and decreased proprioception, significantly increasing the risk of falls in elderly patients. This can not only lead to further injury but also affect the patient's rehabilitation process. Therefore, there is a need for a leg-splitting cushion to prevent dislocation after hip replacement surgery, which not only helps patients restore normal flexion and abduction functions but also helps them maintain balance and prevent falls, thereby increasing their willingness and ability to participate in rehabilitation training and promoting postoperative recovery. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a postoperative anti-dislocation leg-splitting cushion that can ensure that the cushion does not shift after being subjected to force. After the patient gets up, it is convenient for the operator to quickly place and install the cushion, leaving a gap between the patient's two legs, which can separate the legs and keep the affected limb in an abducted and neutral position.

[0005] The technical solution of this utility model is: this postoperative anti-dislocation leg-split seat cushion includes a base plate (1), an installation component (2), a rotating shaft (3), a top plate (4), and a seat cushion component (7);

[0006] The bottom and top of the base plate are respectively equipped with mounting components and seat cushion components, and the two ends of the rotating shaft are rotatably connected to the top of the base plate and movably connected to the top plate, respectively.

[0007] The mounting assembly includes a mounting plate (201), a support sleeve (202), a spring (203), a rack (204), a gear (205), a threaded sleeve (206), a screw (207), and a clamping plate (208). The support sleeve is fixedly connected inside the mounting plate, and the spring is fixedly connected inside the support sleeve. The top of the spring is fixedly connected to the bottom of the base plate. The rack is fixedly connected to the bottom of the base plate. The gear is meshed with the outer wall of the rack. The threaded sleeve is fixedly connected inside the gear. The two ends of the screw are respectively connected to the internal thread of the threaded sleeve and the clamping plate.

[0008] The seat cushion assembly includes a seat cushion body (703) and a leg post (704), with the leg post fixed to the middle of one side of the seat cushion body.

[0009] When the patient sits on the cushion, pressure is applied, causing the cushion assembly to move within the mounting plate. The base plate moves the rack downwards, which in turn rotates the threaded sleeve on the gear against the outer wall of the screw. The screw then moves the clamping plate along the threaded sleeve, thus clamping and positioning the cushion body using the clamping plates on both sides of the mounting plate. After the patient stands up, the spring returns to its original position, and the clamping plates move outwards, disengaging from the cushion assembly, allowing the operator to quickly place and install the cushion. The leg-split column creates a gap between the patient's legs, effectively separating them and maintaining the affected limb in an abducted, neutral position. Attached Figure Description

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this postoperative anti-dislocation leg-split seat cushion includes a base plate 1, a mounting assembly 2, a pivot 3, a top plate 4, and a seat cushion assembly 7.

[0017] The bottom and top of the base plate are respectively equipped with mounting components and seat cushion components, and the two ends of the rotating shaft are rotatably connected to the top of the base plate and movably connected to the top plate, respectively.

[0018] The mounting assembly includes a mounting plate 201, a support sleeve 202, a spring 203, a rack 204, a gear 205, a threaded sleeve 206, a screw 207, and a clamping plate 208. The support sleeve is fixedly connected inside the mounting plate, and the spring is fixedly connected inside the support sleeve. The top of the spring is fixedly connected to the bottom of the base plate. The rack is fixedly connected to the bottom of the base plate. The gear is meshed with the outer wall of the rack. The threaded sleeve is fixedly connected inside the gear. The two ends of the screw are respectively connected to the internal thread of the threaded sleeve and the clamping plate.

[0019] like Figure 5 As shown, the seat cushion assembly includes a seat cushion body 703 and a leg post 704, with the leg post fixed to the middle position of one side of the seat cushion body.

[0020] When the patient sits on the cushion, pressure is applied, causing the cushion assembly to move within the mounting plate. The base plate moves the rack downwards, which in turn rotates the threaded sleeve on the gear against the outer wall of the screw. The screw then moves the clamping plate along the threaded sleeve, thus clamping and positioning the cushion body using the clamping plates on both sides of the mounting plate. After the patient stands up, the spring returns to its original position, and the clamping plates move outwards, disengaging from the cushion assembly, allowing the operator to quickly place and install the cushion. The leg-split column creates a gap between the patient's legs, effectively separating them and maintaining the affected limb in an abducted, neutral position.

[0021] Preferably, the inner diameter of the threaded sleeve matches the outer diameter of the screw, and the outer wall of the screw fits against the inner wall of the threaded sleeve. This strengthens the connection between the threaded sleeve 206 and the screw 207, allowing the gear 205 to rotate, which in turn drives the threaded sleeve 206 to rotate on the outer wall of the screw 207. This allows the screw 207 to drive the clamping plate 208 to clamp the sides of the seat.

[0022] Preferably, the pivot extends through the top plate. This design makes the connection between the pivot and the top plate more secure.

[0023] Preferably, an electric push rod 5 is movably connected to the bottom of the top plate, and a remote control 6 is fixedly connected to one side of the bottom plate. If the patient needs to stand up, the remote control can be used to open the electric push rod, and the electric push rod can drive one end of the top plate to move, so that the top plate can be tilted at an angle by means of the pivot at the other end, thus assisting the patient to stand up from the seat.

[0024] Preferably, the seat cushion assembly further includes a hook and loop fastener side 701 and a hook and loop fastener side 702, with one side of the hook and loop fastener side adhered to the hook and loop fastener side, and the other side of the hook and loop fastener side fixedly connected to the seat cushion body. This structure makes installation and disassembly relatively convenient.

[0025] Preferably, there are multiple seat cushion bodies, with the uppermost seat cushion body being attached to the top plate via a Velcro front side. The dimensions of the Velcro front side and the Velcro back side are the same. This allows for the attachment of multiple seat cushion bodies as needed, enabling overall height adjustment.

[0026] Preferably, the leg support has a U-shaped cross-section, with the curved portion close to the human body. This ensures a better fit and greater patient comfort.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
