Description

Technical Field

[0001] The present invention particularly relates to a device for preventing hip dislocation after hip replacement surgery. Background Art

[0002] The hip joint is a typical ball-and-socket joint, consisting of the femoral head and acetabulum. Hip replacement, also known as total hip replacement, involves attaching an artificial prosthesis (femoral and acetabulum components) to healthy bone using bone cement and screws to replace the diseased joint and restore normal hip function. It is a mature and reliable treatment.

[0003] Post-hip replacement surgery requires patients to maintain certain postures and positions. From a medical perspective, this position is primarily related to the surgical approach, specifically the incision. Different hip replacements involve different locations on the hip scar, and different postures and positions are used for each surgical approach to prevent post-operative hip dislocation.

[0004] Therefore, after the body position is set, how to maintain the inconvenient body position plays an important role in preventing hip dislocation after hip replacement surgery.

[0005] Currently, in clinical practice, most patients' body positions are fixed by placing a pillow between their legs while they are in bed to prevent excessive external rotation of the hip joint; some patients' lower limbs are fixed by placing a wedge-shaped cushion around their legs.

[0006] This approach has the following disadvantages:

[0007] 1. Since the fixing blocks such as pillows or wedge-shaped cushions are all prefabricated, however, for patients of different body shapes and different body positions, such prefabricated fixing devices are bound to achieve a good fixing effect;

[0008] 2. Due to the need to improve the fixation effect, many pillows or cushions are needed for fixation, which will inevitably cause the bed surface to be messy and bring a lot of inconvenience to patients and medical staff. Summary of the Invention

[0009] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a hip replacement surgery anti-dislocation device, which can improve the fixation effect after hip replacement surgery and thus play a good anti-dislocation role.

[0010] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: a device for preventing hip dislocation after hip replacement surgery, comprising:

[0011] There are two positioning plates, which are arranged on the bed surface opposite to each other on the left and right sides;

[0012] There are two clamping fixing members, which are respectively arranged on the two positioning plates and are used for clamping and fixing on the bed; and

[0013] The binding fixing parts include multiple binding blocks and multiple locking parts. The multiple binding blocks are hinged in sequence through the central axis to form a strip shape. The two binding blocks at the head and tail are respectively fixedly connected to the end parts on the inner side of the two positioning plates. A locking part is provided between each two adjacent binding blocks. The locking part is used to lock the angle between the two binding blocks.

[0014] Furthermore, the locking piece includes an internal gear and an external gear, the internal gear is arranged in the axial hole of one of the locking blocks of one of the two adjacent bundling blocks, the center shaft is fixed to the other bundling block and can be slidably inserted in the internal gear, the external gear is sleeved and fixed on the center shaft, and the center shaft is slid, and the external gear can be inserted in the internal gear and engage with the internal gear.

[0015] Furthermore, the locking member also includes an elastic member, which is sleeved on the central shaft and abuts between the two binding blocks. When the elastic member is in a natural state, the external gear is meshed with the internal gear.

[0016] Furthermore, the binding fixture further comprises a pushing assembly, which is connected to all the binding members and can push two adjacent binding blocks to slide along the central axis until the outer gear is disengaged from the inner gear.

[0017] Furthermore, the pushing assembly includes multiple mounting disks, rotating disks, first airbags and inflation devices. Each of the central axes is provided with one of the first airbags, two mounting disks and two rotating disks. Each end of the first airbag is provided with a mounting disk, and the two rotating disks are respectively provided on the end surfaces opposite to each other of the two mounting disks. The inflation device is connected to all the first airbags through multiple first air tubes. When the inflation device starts to inflate and drive the first airbag to expand axially along the central axis, it can push the two mounting disks to move away from each other until the two rotating disks abut against the two bundling blocks and push the two bundling blocks to move until the outer gear disengages from the inner gear.

[0018] Furthermore, it also includes an auxiliary locking support member, which is connected between the two binding blocks and is used to assist in locking the two binding blocks.

[0019] Furthermore, the auxiliary locking support member includes a support rod, a sleeve rod and a clamping member that are slidably connected to each other, and the two ends of the support rod and the sleeve rod are respectively hinged to the ends of the two binding blocks away from the bed surface. The locking member is connected to the support rod and the sleeve rod for locking and fixing the support rod and the sleeve rod.

[0020] Furthermore, the holding member includes a second airbag and a second air tube, and all the second airbags are connected to the inflation device through the second air tube.

[0021] Beneficial effects of the present invention:

[0022] When in use, first put all the locking parts in the unlocked state, then place the positioning plate on one side at the appropriate position at the end of the bed, then fix the clamping fixture on this side to the bed body, then pass the binding fixture 300 around the part that needs to be bound, then make the other positioning plate and the clamping fixture on the other side of the bed surface, then the patient adjusts the body position and makes all the binding blocks close to the body, then locks all the binding blocks through the locking parts, and then fixes the remaining clamping fixtures to the bed body, which can play the role of binding and fixing the patient, preventing the replaced hip joint from being dislocated due to changes in body position during the patient's body recovery process.

[0023] The above-mentioned anti-slip device after hip replacement surgery is used. Since the binding and fixing part 300 can change its shape according to the patient's body shape, body position and the state that needs to be bound and fixed, and since the binding block can fit tightly against the human body, it can adapt to the position fixation of patients of any body shape and body position, thereby forming a good fixing effect and playing a good anti-slip effect.

DETAILED DESCRIPTION

[0032] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0033] See Figures 1 to 5 The present invention provides a device for preventing hip joint dislocation after hip replacement surgery, including a positioning plate 100, a clamping fixture 200 and a binding fixture 300.

[0034] Specifically, there are two positioning plates 100, which are disposed on the bed surface in opposite directions. There are two clamping fixtures 200, which are disposed on each of the two positioning plates 100 for clamping and securing the bed surface. In a specific implementation, the clamping fixtures 200 can be conventionally used clamps capable of locking and securing, or can be secured by bolts or other means.

[0035] The binding fixture 300 includes a plurality of binding blocks 310 and a plurality of locking members 320. The binding blocks 310 are sequentially hinged through a central axis to form a strip shape. The first and last binding blocks 310 are respectively fixedly connected to the inner ends of the two positioning plates 100. A locking member 320 is provided between each adjacent binding block 310 to lock the angle between the two binding blocks 310.

[0036] When in use, first put all the locking pieces 320 in the unlocked state, then place the positioning plate 100 on one side at a suitable position at the end of the bed, then fix the clamping fixture 200 on this side to the bed body, then pass the binding fixture 300 around the part that needs to be bound, then make the other positioning plate 100 and the clamping fixture 200 on the other side of the bed, then the patient adjusts the body position and makes all the binding blocks 310 close to the body, then lock all the binding blocks 310 through the locking piece 320, and then fix the remaining clamping fixtures 200 to the bed body, which can play the role of binding and fixing the patient, preventing the replaced hip joint from being dislocated due to changes in body position during the patient's body recovery process.

[0037] The above-mentioned anti-slip device after hip replacement surgery is used. Since the binding and fixing part 300 can change its shape according to the patient's body shape, body position and the state that needs to be bound and shaped, and since the binding block 310 can fit tightly against the human body, it can adapt to the position fixation of patients of any body shape and body position, thereby forming a good shaping effect and playing a good anti-slip effect.

[0038] In this embodiment, the locking member 320 includes an internal gear 321 and an external gear 322. The internal gear 321 is disposed within the axial hole of one of the two adjacent binding blocks 310. The central shaft is fixed to the other binding block 310 and can be slidably inserted into the internal gear 321. The external gear 322 is sleeved and fixed on the central shaft. The central shaft slides, and the external gear 322 can be inserted into the internal gear 321 and mesh with the internal gear 321.

[0039] During use, in a normal state, all the inner gears 321 and outer gears 322 are in a non-meshing state. When it is necessary to lock the angle between the two binding blocks 310, the binding blocks 310 are slid along the central axis so that the outer gears 322 are inserted into the inner gears 321. This locks the angle between the two binding blocks 310.

[0040] As a preferred embodiment, the locking member 320 further includes an elastic member 323. The elastic member 323 is sleeved on the central axis and abuts between the two binding blocks 310. When the elastic member 323 is in a natural state, the outer gear 322 is meshed with the inner gear 321.

[0041] When not in use, the outer gear 322 meshes with the inner gear 321, and the shape of the binding fixture 300 is fixed. When binding is required, the binding block 310 of the portion to be bound is first moved along the central axis, and the angle of the binding block 310 is adjusted so that the binding block 310 is pressed tightly against the human body. The thrust is then released, and the elastic member 323 pushes the binding block 310 back along the central axis, causing the outer gear 322 to reinsert into the inner gear 321. The angle between the two binding blocks 310 is then fixed using the same method. The angle of the second binding block 310 is then adjusted and locked. This method can increase the speed of locking and fixing.

[0042] As a more preferred embodiment, the locking member 320 further includes a pushing assembly 330 , which is connected to all the binding members and can push two adjacent binding blocks 310 to slide along the central axis until the outer gear 322 is disengaged from the inner gear 321 .

[0043] During use, the bundling blocks 310 can be pushed along the central axis by pushing the assembly 330 to be quickly unlocked, and the elastic member 323 contracts to make all the bundling blocks 310 in a free state. Then the positioning plate 100 is moved to allow the bundling blocks 310 to be freely overlapped on the patient's body. Then, under the action of the elastic member 323, the positions of all the bundling blocks 310 are restored, and the inner and outer gears 322 are re-engaged to lock the angles of the bundling blocks 310, completing the bundling fixation of the bundling fixing member 300.

[0044] Specifically, the pushing assembly 330 includes a plurality of mounting disks 331, a rotating disk 332, a first airbag 333 and an inflation device. A first airbag 333, two mounting disks 331 and two rotating disks 332 are sleeved on each central axis. A mounting disk 331 is provided at both ends of the first airbag 333, and two rotating disks 332 are respectively provided on the end faces facing away from the two mounting disks 331. The inflation device is connected to all the first airbags 333 through a plurality of first air tubes. When the inflation device starts to inflate and drive the first airbag 333 to expand axially along the central axis, it can push the two mounting disks 331 to move away from each other until the two rotating disks 332 abut against the two bundling blocks 310 and push the two bundling blocks 310 to move until the outer gear 322 disengages from the inner gear 321.

[0045] When the airbag is not inflated, the elastic member 323 is in a natural state. When the airbag is inflated, the elastic member 323 can push the binding member to move and complete the unlocking function. The purpose of the rotating disk 332 is to facilitate the two hinged binding blocks 310 to freely adjust their angles.

[0046] As a more preferred embodiment, the device further includes an auxiliary locking support 400, which is connected between the two binding blocks 310 and is used to assist in locking the two binding blocks 310. After the angle adjustment binding is completed, the auxiliary locking support 400 provides auxiliary support to prevent the angle between the hinged binding blocks 310 from changing, further improving the fixing effect.

[0047] In this embodiment, the auxiliary locking support 400 comprises a support rod 410, a sleeve rod 420, and a locking member 320 that are slidably connected to each other. The ends of the support rod 410 and sleeve rod 420 are hingedly connected to the ends of the two binding blocks 310 away from the bed surface. The locking member 320 is connected to the support rod 410 and sleeve rod 420 to lock and secure them.

[0048] Before bundling, all the locking members 320 are unlocked, and after bundling is completed, all the locking members 320 are locked, which can play a role of auxiliary support and positioning.

[0049] Specifically, the locking member 320 includes a second air bag 431 and a second air tube 432. All the second air bags 431 are connected to the inflation device through the second air tube 432.

[0050] During use, when all second airbags 431 are inflated through the inflation device, the second airbags 431 expand, securing the support rod 410 and the sleeve rod 420. After use, the air in the second airbags 431 can be released. In practice, a three-way connection can be used between the first and second airbags 333, 431, and the inflation device. Pressure valves and pressure relief valves can be installed on both airflow branches. The air pressures within the first and second airbags 333, 431 can be adjusted accordingly.

[0051] How to use the above anti-dislocation device after hip replacement surgery:

[0052] During use, first inflate the first airbag 333 so that all the external gears 322 are in a disengaged state, then place the positioning plate 100 on one side at a suitable position on the bed surface, then fix the clamping fixture 200 on this side to the bed body, then pass the binding fixture 300 around the part that needs to be bound, so that the other positioning plate 100 and the clamping fixture 200 are located on the other side of the bed surface, at this time all the binding blocks are in a naturally rotatable state, then the patient adjusts the body position, the binding block 310 is naturally close to the patient's body, then the gas in the first airbag 333 is released, so that the internal and external gears 322 are in a meshing state, which can fix the shape of the binding fixture and play a role in binding positioning, finally, inflate the second airbag through the inflation device to fix the position of the support rod between the sleeve rod, and the auxiliary locking support member plays an auxiliary supporting and fixing role.

[0053] Finally, the remaining clamping fixtures 200 are fixed to the bed, which can play a role in binding and fixing the patient, thereby preventing the replaced hip joint from being dislocated due to external changes in the patient's body during the recovery process.

[0054] The above-mentioned anti-slip device after hip replacement surgery is used. Since the binding and fixing part 300 can change its shape according to the patient's body shape, body position and the state that needs to be bound and shaped, and since the binding block 310 can fit tightly against the human body, it can adapt to the position fixation of patients of any body shape and body position, thereby forming a good shaping effect and playing a good anti-slip effect.

[0055] In addition, the arrangement of the elastic member 323 and the pushing assembly 330 can achieve rapid fixing or releasing of the binding fixture. The auxiliary locking support member 400 can further support and improve the fixing effect.
