Description

Technical Field

[0001] The utility model relates to the field of traction frames, in particular to a freely adjustable traction frame. Background Technique

[0002] Orthopedic clinical is a medical field that studies, diagnoses, and treats diseases of the musculoskeletal system. During orthopedic clinical practice, a traction frame is required. A traction frame is a medical device mainly used to assist traction and fixation during fractures and joint dislocation surgeries. Through the traction frame, doctors can better operate on the patient's bones, thus ensuring the smooth progress of the surgical procedure.

[0003] When some existing traction frames adjust the angle of the rotating rod body, manual adjustment is used, resulting in different adjustment angles of the two rotating rod bodies during the adjustment process, thus leading to poor traction effect and prolonging the patient's recovery period. Therefore, those skilled in the art have provided a freely adjustable traction frame to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a freely adjustable traction frame is proposed. By means of bolts, the first connecting circular through-hole plate and the second connecting circular through-hole plate are clamped together, thereby extending the multi-stage telescopic rod, enabling the second slider to slide within the rotating rod body, so that the two rotating rod bodies have the same angle adjustment.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A freely adjustable traction frame, including a base mechanism. On one side surface of the upper end of the base mechanism away from the center, two rotating rod mechanisms are rotatably arranged. On both side surfaces of the inner walls of the two rotating rod mechanisms, telescopic mechanisms are clamped. On one side surface of each of the two rotating rod mechanisms, displacement mechanisms are slidably arranged. On the upper surface of each of the two displacement mechanisms, an adjustment mechanism is fixedly connected. Each of the two rotating rod mechanisms includes a rotating rod body. On one side surface of each of the two rotating rod bodies, a chute is provided. On one side surface of each of the two chutes, a second slider is slidably arranged. On one side surface of each of the two second sliders, a first connecting circular through-hole plate is fixedly connected.

[0006] The telescopic mechanism includes a fixed box. At the center of the interior of the fixed box, a partition plate is fixedly connected. At the center of both side surfaces of the two partition plates, multi-stage telescopic rods are fixedly connected. On one side surface of each of the two multi-stage telescopic rods, a second connecting circular through-hole plate is fixedly connected. The adjustment mechanism includes a motor protection box. On one side surface of the interior of the motor protection box, a rotating motor is fixedly connected. The output end of the rotating motor is fixedly connected with a second arc-shaped block.

[0007] Through the above technical solution, through the mutual cooperation of the second sliders on both sides of the inner wall of the rotating rod main body and the multi-stage telescopic rod inside the fixed box, the first connecting circular through-hole plate fixedly connected to one side surface of the second slider and the second connecting circular through-hole plate fixedly connected to one side surface of the multi-stage telescopic rod are clamped together under the action of bolts. Then, by extending the multi-stage telescopic rod, the two second sliders are displaced inside the rotating rod main body. In this way, the angles of the two rotating rod main bodies can be adjusted simultaneously, ensuring that the two legs of the patient receive the same rotation angle, thus realizing more precise traction for the operation. By means of the motor protection box, the second arc-shaped block is rotated by the rotating motor inside it. In this way, the inclination of the patient's foot can be adjusted, so that the patient's foot can have good comfort.

[0008] Further, the base mechanism includes a base main body, and a control panel is fixedly connected to the front side surface of the upper end of the base main body;

[0009] Through the above technical solution, the first electric telescopic rod, the second electric telescopic rod and the third electric telescopic rod can be turned on or off under the action of the control panel.

[0010] Further, a first electric telescopic rod is fixedly connected to the center of the upper end surface of the base main body, a lying board is fixedly connected to the upper end surface of the first electric telescopic rod, and a gear block is fixedly connected to one side surface of the upper end of the lying board;

[0011] Through the above technical solution, the patient can lie in the lying board, and the gear block can play a role in limiting the patient.

[0012] Further, first sliders are slidably arranged on the upper end surfaces of the two rotating rod main bodies, second electric telescopic rods are fixedly connected to the upper end surfaces of the two first sliders, and a first arc-shaped block is fixedly connected to the upper end surfaces of the two second electric telescopic rods;

[0013] Through the above technical solution, the first slider can displace the second electric telescopic rod, and the second electric telescopic rod can extend or shorten the first arc-shaped block.

[0014] Further, the two displacement mechanisms include fixed blocks, connecting blocks are fixedly connected to the lower end surfaces of the two fixed blocks, and rollers are rotatably arranged on the front and rear side surfaces of the two connecting blocks;

[0015] Through the above technical solution, the main function of the connecting block is to serve as a connection medium between the fixed block and the roller, and the roller can displace the fixed block.

[0016] Further, a sliding rod is fixedly connected to one side surface of each of the two fixing blocks, and a third electric telescopic rod is fixedly connected to the upper surface of each of the two fixing blocks;

[0017] Through the above technical solution, the distance between the fixing block and the main body of the rotating rod can be changed under the action of the sliding rod, and the motor protection box can be extended or shortened under the action of the third electric telescopic rod.

[0018] Further, a connecting plate is fixedly connected to the lower surface of each of the two motor protection boxes, and a fixing band is fixedly connected to one side surface of each of the two second arc-shaped blocks;

[0019] Through the above technical solution, the connecting plate can serve as a connection medium between the motor protection box and the third electric telescopic rod, and the fixing band can play a role in limiting and fixing the patient's feet.

[0020] The utility model has the following beneficial effects:

[0021] 1. For a freely adjustable traction frame proposed by the utility model, the second connecting circular through-hole plate on one side of the multi-stage telescopic rod and the first connecting circular through-hole plate fixedly connected to one side surface of the second slider are clamped together under the action of bolts, and then by extending or shortening the multi-stage telescopic rod, the main body of the rotating rod is adjusted by the same angle under the action of the second slider, so that the two legs of the patient receive the same rotation angle, thereby realizing more precise traction for the operation and enabling the operation to be better completed.

[0022] 2. For a freely adjustable traction frame proposed by the utility model, when the patient's feet are better fixed on the second arc-shaped block under the action of the fixing band, the second arc-shaped block is adjusted in angle under the action of the rotating motor inside the motor protection box. In this way, the feet fixed on the second arc-shaped block can be rotated left and right, but the rotation amplitude is very small. In this way, the patient's feet can be prevented from being in the same state for a long time, thereby reducing the patient's comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Referring to Figures 1-2 , both of the two rotating rod mechanisms 2 include a rotating rod main body 201. A chute 205 is provided on one side surface of the two rotating rod main bodies 201. A second slider 206 is slidably arranged on one side surface of the two chutes 205. A first connecting circular through-hole plate 207 is fixedly connected to one side surface of the two second sliders 206. A first slider 204 is slidably arranged on the upper end surface of the two rotating rod main bodies 201. A second electric telescopic rod 203 is fixedly connected to the upper end surface of the two first sliders 204. A first arc-shaped block 202 is fixedly connected to the upper end surface of the two second electric telescopic rods 203.

[0035] Under the action of the chute 205, the second slider 206 can slide inside it, and under the action of the first slider 204, the second electric telescopic rod 203 can be displaced. Under the action of the first arc-shaped block 202, the legs of the patient can be supported.

[0036] Referring to Figure 3 , the telescopic mechanism 3 includes a fixed box 301. A partition plate 302 is fixedly connected to the center of the inside of the fixed box 301.

[0037] Under the action of the two multi-stage telescopic rods 303, the second connecting circular through-hole plate 304 fixedly connected to one side surface of it can be extended or shortened.

[0038] Referring to Figure 1 , both of the two displacement mechanisms 4 include a fixed block 401. A connecting block 402 is fixedly connected to the lower end surface of the two fixed blocks 401. Rollers 403 are rotatably arranged on the front and rear side surfaces of the two connecting blocks 402. A slide rod 405 is fixedly connected to one side surface of the two fixed blocks 401. A third electric telescopic rod 404 is fixedly connected to the upper end surface of the two fixed blocks 401.

[0039] Through the mutual cooperation of the slide rod 405 and the rollers 403, the distance between the rotating rod main body 201 and the fixed block 401 can be changed, and under the action of the third electric telescopic rod 404, the connecting plate 501 can be extended or shortened.

[0040] Referring to Figure 4, the adjusting mechanism 5 includes a motor protection box 502. On one side surface inside the motor protection box 502, a rotating motor 503 is fixedly connected.

Then, through the mutual cooperation of the sliding rod 405 and the roller 403, the fixing block 401 is slid to a suitable position. Then, under the action of the second arc-shaped block 504 and the fixing belt 505, the patient's feet are limited and fixed. Then, the first connecting circular through-hole plate 207 and the second connecting circular through-hole plate 304 are clamped together by bolts, so that the multi-stage telescopic rod 303 and the second slider 206 are clamped together. Then, under the action of the control panel 102, the first electric telescopic rod 104, the second electric telescopic rod 203, and the third electric telescopic rod 404 are extended to suitable positions. Then, under the action of the multi-stage telescopic rod 303, the second connecting circular through-hole plate 304 is extended, so that the angle between the second connecting circular through-hole plate 304 and the first connecting circular through-hole plate 207 changes. At the same time, the second slider 206 slides in the chute 205. In this way, when the angles of the two rotating rod bodies 201 change, they are the same. And under the action of the rotating motor 503, the second arc-shaped block 504 can be rotated, so as to drive the patient's feet to tilt left and right, thereby improving the comfort of the patient.
