Description

Technical Field

[0001] This application relates to the technical field of positioners, and specifically to an orthopedic parallel compression positioner. Background Art

[0002] An orthopedic parallel compression positioner is a precision instrument specifically designed for orthopedic surgeries, aiming to assist surgeons in achieving precise alignment and stable compression of bone fracture ends during fracture reduction and internal fixation surgeries. Such positioners usually have a high degree of adjustability and accuracy to ensure the efficiency and safety of surgical operations.

[0003] The Chinese utility model patent with the publication number of CN221243003U discloses an orthopedic parallel compression positioner. By rotating the knob to drive the rotation of the positive and negative lead screws, the positive and negative lead screws drive the movement inside the moving block, and then the moving block moves inside the slide rail, so as to drive the adjustment of the positions of the positioning cones and sleeves on both sides. This structure facilitates the adjustment of the position. However, this orthopedic parallel compression positioner cannot view the numerical value of the distance length between the first positioning block and the second positioning block. During adjustment, it can only be blindly adjusted, and it is impossible to see how much the distance between the first positioning block and the second positioning changes. Consequently, the magnitude of the compression applied to the fracture sites of the two bones cannot be precisely controlled.

[0004] Therefore, this application provides an orthopedic parallel compression positioner to solve the above problems. Summary of the Utility Model

[0005] This application provides an orthopedic parallel compression positioner, aiming to solve the problems in the background art that the existing orthopedic parallel compression positioner cannot view the numerical value of the distance length between the first positioning block and the second positioning block, can only be blindly adjusted during adjustment, cannot see how much the distance between the first positioning block and the second positioning changes, and consequently cannot precisely control the magnitude of the compression at the fracture sites of the two bones.

[0006] To achieve the above objective, this application provides the following technical solution: An orthopedic parallel compression positioner includes a bracket assembly, two fixed seats and a movable seat that can move relative to each other provided on the bracket assembly, and a clamping mechanism provided on the fixed seats and the movable seat; a length display mechanism for displaying the distance between the fixed seat and the movable seat is provided on the bracket assembly; the length display mechanism includes a scale sleeve fixedly connected to the top end of the fixed seat, and a scale plate fixedly connected to the movable seat is slidably inserted inside the scale sleeve. In this way, when using the orthopedic parallel compression positioner, the length display mechanism can display the length distance between the fixed seat and the movable seat. Through the direct reading of the scale plate, doctors can very precisely control the compression force between the fracture ends. The treatment process with specific numerical records is convenient for doctors to track the rehabilitation progress of patients, provides data support for subsequent treatment plans, and is also convenient for scientific research and teaching use.

[0007] Preferably, the graduations on the scale sleeve are arranged in the direction from the fixed seat towards the movable seat, and the arrangement direction of the graduations on the scale plate is opposite to that of the graduations on the scale sleeve.

[0008] Preferably, the bracket assembly includes a fixed U-shaped frame and a movable U-shaped frame. The fixed U-shaped frame and the movable U-shaped frame are connected by an adjusting member. The fixed seat is fixedly sleeved outside the fixed U-shaped frame, and the movable seat is fixedly sleeved outside the movable U-shaped frame. By changing the length of the bracket assembly, the orthopedic parallel compression locator can be used to clamp and compress and adjust the arm bones or leg bones of different people.

[0009] Preferably, the adjusting member includes a driving screw rod rotatably inserted through a round hole at one end of the movable U-shaped frame, and one end of the driving screw rod is threadedly inserted into one end of the fixed U-shaped frame. The other end of the driving screw rod is fixedly connected with a rotating plate, and a guiding slide rod fixedly connected with the other end of the movable U-shaped frame is slidably inserted through the other end of the fixed U-shaped frame.

Through the direct reading of the scale plate, doctors can very precisely control the compression force between the fracture ends. The treatment process with specific numerical records is convenient for doctors to track the rehabilitation progress of patients, provides data support for subsequent treatment plans, and is also convenient for scientific research and teaching.

[0014] This application uses the cooperation of the fixed U-shaped frame, the movable U-shaped frame, the driving screw rod and the guiding slide rod to form a bracket assembly. Then, the cooperation of the driving screw rod and the guiding slide rod can adjust the distance between the fixed U-shaped frame and the movable U-shaped frame.

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application

[0021] Embodiment 1

[0022] This embodiment provides an orthopedic parallel compression locator, as Figures 1-3 shown. The orthopedic parallel compression locator includes a bracket assembly 1, two relatively movable fixed seats 2 and movable seats 3 provided on the bracket assembly 1, and a clamping mechanism 4 provided on the fixed seats 2 and the movable seats 3 for clamping and fixing the leg bone or hand bone

[0023] A length display mechanism 5 for displaying the distance between the fixed seat 2 and the movable seat 3 is provided on the bracket assembly 1; the length display mechanism 5 includes a scale sleeve 51 fixedly connected to the top end of the fixed seat 2, and a scale plate 52 fixedly connected to the movable seat 3 is slidably inserted into the scale sleeve 51; the length display mechanism 5 can be used to display the length distance between the fixed seat 2 and the movable seat 3, which is convenient for medical staff to see how much the distance between the fixed seat 2 and the movable seat 3 is, and then convenient for medical staff to watch the change of the distance between the fixed seat 2 and the movable seat 3 to adjust the distance between the fixed seat 2 and the movable seat 3 and change the compression force between the two broken bones; through the direct reading of the length display mechanism 5, doctors can very precisely control the compression force between the fracture ends, which is crucial for promoting fracture healing, because appropriate pressure can stimulate the growth of bone cells and accelerate the fracture healing process; as the fracture heals, it may be necessary to adjust the compression force to adapt to the healing needs at different stages; this method allows for easy adjustment according to the healing situation, avoiding excessive or insufficient pressure, thereby optimizing the treatment effect; compared with frequent surgical adjustments, this external adjustment method reduces the intrusion and risk to the patient and improves the safety and patient comfort of the treatment; the length display mechanism 5 is not only used for adjustment, but also can be used as an intuitive indicator of the healing progress. Doctors and patients can generally understand the fracture healing situation by observing the distance change, enhancing the transparency of the treatment and the confidence of the patient; appropriate compression can help maintain the correct alignment of the fracture site, prevent healing deformities, and thus promote the recovery of joint function and limb strength; the treatment process with specific numerical records is convenient for doctors to track the rehabilitation progress of patients, provide data support for subsequent treatment plans, and is also convenient for scientific research and teaching use;

[0024] It should be noted that: the scale numbers on the scale sleeve 51 are arranged in the direction from the fixed seat 2 towards the movable seat 3, and the arrangement direction of the scale numbers on the scale plate 52 is opposite to the arrangement direction of the scale numbers on the scale sleeve 51; the initial value on the scale plate 52 starts counting from the end value on the scale sleeve 51;

[0025] During use, first, the fixed seat 2 and the movable seat 3 are respectively fixed on the two broken bones through the clamping mechanism 4, and then by observing the value on the scale plate 52 at the intersection of the scale plate 52 and the scale sleeve 51, the distance between the fixed seat 2 and the movable seat 3 can be seen, and then by adjusting the distance between the movable seat 3 and the fixed seat 2, the compression force between the two bones can be changed.

[0026] Specifically, the clamping mechanism 4 includes a fixed plate 41, a movable plate 42, a fixing bolt 43 and a fixing nut 44. The fixed plate 41 is fixedly connected to the bottom ends of the fixed seat 2 and the movable seat 3. The movable plate 42 is arranged below the fixed plate 41. Through holes 45 for inserting the fixing bolt 43 are formed in both the fixed plate 41 and the movable plate 42. The fixing nut 44 is threadedly sleeved on the outside of the fixing bolt 43. The device uses the cooperation of two opposite fixed plates 41 and movable plates 42, as well as the fixing bolt 43 and the fixing nut 44 to fix the fixed seat 2 and the movable seat 3 on the fractured bone. The cooperation of the fixing bolt 43 and the fixing nut 44 provides firm fixation and is simple and convenient to operate.

[0027] During use, first, the fixed plate 41 is attached to the outside of the arm or leg, then the movable plate 42 is attached to the other side of the arm or leg, and then the fixed plate 41 and the movable plate 42 are fixed together through the cooperation of the fixing bolt 43 and the fixing nut 44, thereby completing the position fixation of the fixed seat 2 and the movable seat 3.

[0028] Furthermore, to prevent the loss of the fixing nut 44: the top end of the fixing nut 44 is fixedly connected to the bottom end of the movable plate 42. By fixing the fixing nut 44 on the movable plate 42, the phenomenon of the fixing nut 44 being lost is avoided.

[0029] Embodiment 2

[0030] Different from Embodiment 1, (in the case where the lengths of different human bones are inconsistent, there will be problems of the bracket assembly 1 being too long or too short). For this reason, the bracket assembly 1 includes a fixed U-shaped frame 11 and a movable U-shaped frame 12. The fixed U-shaped frame 11 and the movable U-shaped frame 12 are connected by an adjusting member. The fixed seat 2 is fixedly sleeved on the outside of the fixed U-shaped frame 11, and the movable seat 3 is fixedly sleeved on the outside of the movable U-shaped frame 12. The adjusting member includes a driving lead screw 13 rotatably inserted through a round hole at one end of the movable U-shaped frame 12. One end of the driving lead screw 13 is threadedly inserted into one end of the fixed U-shaped frame 11. The other end of the driving lead screw 13 is fixedly connected to a rotating plate 131. A guiding slide bar 14 fixedly connected to the other end of the movable U-shaped frame 12 is slidably inserted into the other end of the fixed U-shaped frame 11. An arc-shaped groove is formed on the side of the rotating plate 131.

[0031] When installing the fixed seat 2 and the movable seat 3, first adjust the length positions of the fixed seat 2 and the movable seat 3 according to the length of the bone, and then adjust the total length of the bracket assembly 1. During the adjustment, when the driving screw rod 13 is rotated clockwise, the total length of the bracket assembly 1 becomes shorter under the cooperation of the guiding slide rod 14, that is, the distance between the fixed seat 2 and the movable seat 3 becomes shorter. At this time, the movable seat 3 drives the scale plate 52 to move into the scale sleeve 51; when the driving screw rod 13 is rotated counterclockwise, the total length of the bracket assembly 1 becomes longer under the cooperation of the guiding slide rod 14, that is, the distance between the fixed seat 2 and the movable seat 3 becomes longer. At this time, the movable seat 3 drives the scale plate 52 to move out of the scale sleeve 51.

[0032] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
