Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a hip replacement surgery auxiliary device and a use method thereof. Background Art

[0002] Hip replacement is the process of fixing an artificial prosthesis, consisting of a femoral part and an acetabulum part, to normal bone using bone cement and screws to replace the diseased joint and reconstruct the normal function of the patient's hip joint.

It includes an operating table, a fixing seat is embedded in the upper surface of the operating table, and two support blocks are symmetrically fixedly connected to the upper surface of the fixing seat. A lifting assembly is arranged inside the fixing seat and the support block, and a movable sleeve is connected through the lifting assembly, and the top of the movable sleeve extends outward through the top wall of the support block and is fixedly connected to a fixing frame, and a fixing bar is slidably connected to the inner wall of the fixing frame, and a limiting assembly is arranged between the fixing frame and the fixing bar. When the prosthesis auxiliary stabilization device used in artificial hip replacement surgery is fixed with screws, during the knocking process, the femoral part of the prosthesis can only slide in one direction between the two semicircular sleeves, so that the femoral part of the prosthesis will not tilt.

[0004] The above technical solution can ensure the stability of the prosthesis during the operation, but before hip replacement, the patient's legs need to be lifted and separated from the operating table so that medical staff can wrap and bandage the patient's legs and waist. The patient also needs to lie on his side to fully expose the position where the hip replacement operation is required for the operation. In the existing operation, medical staff need to manually lift the patient's legs and push the patient to turn over, which is not conducive to ensuring the stability of the patient after lying on his side, so improvement is needed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a hip replacement surgery auxiliary device and a method of using the same.

[0009] Compared with the prior art, the present application can bind the patient's legs and lift both legs of the patient at the same time, which is convenient for wrapping the patient's legs and the operating table, and can also drive the patient to flip over to fully expose the patient's surgical position, facilitate disinfection and marking operations, and facilitate subsequent operations. At the same time, it can effectively limit the position of the patient's legs and feet, which helps to ensure the stability of the patient's body during later operations.

[0010] Preferably, the foot binding mechanism includes a moving opening at one end of the side flap plate, a moving plate is slidably installed in the moving opening, a positioning mechanism is provided on the moving opening, a bearing plate is slidably installed at the lower end of the moving plate, both ends of the double-head telescopic rod are located on one side of the two bearing plates, a telescopic assembly is slidably installed at the end of the moving plate away from the side flap plate, a foot binding assembly is fixed to the upper end of the telescopic assembly, a through opening is provided at the end of the moving plate away from the side flap plate, an oblique push rod is penetrated through the through opening, the upper and lower ends of the oblique push rod are respectively rotatably connected to the bearing plate and the foot binding assembly, and a clamping mechanism is provided on the foot binding assembly.

[0012] Preferably, the positioning mechanism includes two spring members fixed on the side wall at one end of the moving opening, one end of the two spring members is fixed on a moving plate that passes through the moving opening, a fastening bolt member is screwed on the lower end of the side flip plate, and one end of the fastening bolt member extends into the moving opening and contacts the moving plate.

[0013] Furthermore, when the patient is turned sideways, the spring member can cause the movable plate to slowly fall down, and at the same time, by rotating the fastening bolt member, one end of the fastening bolt member extends into the moving opening and contacts the movable plate, thereby effectively fixing the position of the movable plate and ensuring the stability of the patient's legs.

[0014] Preferably, the fastening mechanism comprises a T-shaped rod rotatably connected to the lower end of the foot binding assembly, a limiting opening is provided on the movable plate, and the T-shaped rod is penetrated and arranged in the limiting opening.

[0015] Furthermore, when the foot binding assembly moves toward the direction of the movable plate, the lower end of the T-bar overlaps with the limit opening, making it easier for the T-bar to pass through the limit opening. When the foot binding assembly collides with the movable plate, the lower end of the T-bar extends to the lower end of the movable plate, and the T-bar is rotated so that its lower end and the limit opening are staggered, which can effectively fix the position of the foot binding assembly.

During actual preparation, the spring component can also be fixed between the two contact plates to facilitate the relative movement of the two contact plates when there is no external force or the external force disappears, thereby reducing the distance between the two contact plates. At the same time, the opposite sides of the two contact plates are inclined. During operation, the inclined end of the pressure plate member and the inclined end of the contact plate are in conflict with each other, thereby facilitating stable movement operation.

[0020] Preferably, the regulating mechanism includes a U-shaped notch opened at the lower end of the side flap, two U-shaped frames are respectively located in the two U-shaped notches, the U-shaped frame is rotatably connected in the U-shaped notch, an elastic plug rod is installed on the side wall at one end of the U-shaped notch, and two plug holes are provided on the side wall at one end of the U-shaped notch, and one end of the elastic plug rod extends into one of the plug holes.

[0022] Preferably, a fixing frame is fixed to the lower end of the movable bed assembly, and linkage plates are penetrated through both ends of the fixing frame, and the two linkage plates are respectively fixed on opposite sides of the two abutment plates.

[0023] Furthermore, the fixed frame and the movable bed assembly are fixedly connected, and the contact plate can be moved at the lower end of the movable bed assembly through the action of the linkage plate.

[0024] Preferably, both sides of the pressure plate member close to the abutment plate are arranged in an arc shape, and the two abutment plates are arranged obliquely close to one end of the pressure plate member, and the inclined ends of the two abutment plates are arranged opposite to each other.

[0025] Furthermore, the inclined ends of the pressure plate and the contact plate can be inclined or arc-shaped according to the situation, so that the pressure plate can squeeze the contact plate to move the contact plate, and a spring component can be fixed between the two contact plates to facilitate the rapid relative movement of the two contact plates when there is no external force or the external force disappears.

[0026] The present invention also provides a method for using a hip replacement surgery auxiliary device, which is applicable to the above-mentioned hip replacement surgery auxiliary device, and comprises the following steps:

[0027] S1. Fixing the bed: Move the movable bed assembly into the operating room and effectively fix the movable bed assembly. At the same time, the patient is also moved into the operating room through the bed and then transferred to the movable bed assembly;

[0028] S2. Preoperative preparation: The patient lies flat on the movable bed assembly with his face upward, and the patient's feet are fixed on two foot binding assemblies respectively. The hydraulic cylinder assembly is operated, so that the top plate can push the double-headed telescopic rod to move away from the movable bed assembly. At the same time, the two ends of the double-headed telescopic rod are respectively in contact with the two bearing plates. As the bearing plates move at the lower end of the movable plate, the oblique push rod can push the foot binding assembly to rise. The stability of the foot binding assembly can be ensured by the telescopic assembly, so that the patient's legs are separated from the movable bed assembly, which is convenient for medical staff to lay the mattress on the movable bed assembly and the side flap and wrap the patient's legs with surgical tape except for the surgical site;

[0029] S3, line disinfection: the hydraulic cylinder assembly contracts to lower the foot binding assembly and make the T-bar pass through the limit opening, rotate the limit opening so that the T-bar and the limit opening are staggered, pull the elastic plug rod at the patient's surgical position to rotate the U-shaped frame, and set the U-shaped frame vertically downward, loosen the elastic plug rod to insert it into the corresponding plug hole to fix the U-shaped frame, and the U-shaped frame will contact the connecting plate on that side. At this time, the hydraulic cylinder assembly contracts and makes the top plate contact the pressure plate part, and the pressure plate part contacts the contact plate, so that the contact plate moves toward the direction of the side flip plate. The contact plate at the position where the U-shaped frame and the connecting plate contact each other can push the connecting plate through the swing rod to flip the side flip plate on that side;

[0030] At this time, the moving plate will move toward the movable bed assembly along the direction of the moving opening, and the moving plate can be slowly dropped by the spring member, while the position of the moving plate can be effectively resisted and fixed by the fastening bolt member;

[0031] At this time, the patient will be transformed from lying flat to lying sideways under the action of the side flip board, and the surgical site will be exposed. The medical staff can mark and disinfect the surgical site so that cutting can be performed according to the markings during subsequent surgery;

[0032] At the same time, the connecting plate on the side of the U-shaped frame that has not rotated will move at the lower end of the side flip plate under the action of the resistance plate on that side and will not rotate.

[0033] Compared with the prior art, the operation mode of the present application is described in detail so that medical staff can quickly understand how it operates, and can perform foot fixation, leg lifting, turning over and other steps according to the operating procedures of hip replacement surgery, so that medical staff can lay medical pads, draw lines and perform disinfection operations.

[0034] The beneficial effects of the present invention are:

[0035] 1. This application can provide power through the hydraulic cylinder assembly to realize automatic leg lifting and turning over operations, which can effectively reduce the operating intensity of medical staff, facilitate medical staff to fix the patient's feet, lift the legs, turn over and other operations, and make it easier to lay medical pads, mark lines and disinfect operations;

[0036] 2. During operation, the opposing ends of the contact plate and the pressure plate can be inclined or arc-shaped as required, so that when the pressure plate moves toward the contact plate, the two contact plates can be pushed apart to provide power for the rotation of the side flap. Then, by controlling the rotation of the U-shaped frame on the corresponding side, the relative position of the connecting plate and the side flap on that side can be limited, so that the side flap can be pushed to flip through the swing rod, driving the patient to flip and expose the surgical position; the connecting plate and the side flap on the other side can move relatively to make the side flap on that side stable;

[0037] 3. The foot binding assembly can effectively fix the patient's feet so as to push the patient's legs and the side flip board apart. At the same time, the T-bar and the limit opening can cooperate to fully fix the feet and the movable board. During surgery, the legs and feet on the side not undergoing surgery can be separated from the foot binding assembly so that the patient can flip over. At the same time, the spring part can make the patient's legs slide down slowly, and the movable board on that side can be effectively fixed by tightening the bolt part to ensure the stability of the leg on the surgical side.
