[0024] Please refer to Figure 1-Figure 8 , this embodiment provides a limb traction device 200 for a fracture patient, the limb traction device 200 for a fracture patient comprises an external fixation bracket 210, a traction frame 220, a traction member 230, a driving unit 240 and a connecting member 250; The external fixation bracket 210 is sleeved on the fractured limb of the patient; the traction frame 220 is connected to the bed frame; the traction member 230 is movably connected to the traction frame 220, and the traction member 230 is located directly above the patient lying on the bed frame, and the traction member 230 is connected to the external fixation bracket 210 through the connecting member 250; the driving unit 240 is connected to the traction member 230; The driving unit 240 is used to drive the traction member 230 to move relative to the traction frame 220 and to retract and release the connecting member 250 .

[0025] Please refer to Figure 1-Figure 8 The working principle of the fracture patient limb traction device 200 is: First, the limb traction device 200 for fractured patients plays an auxiliary role in turning over or changing body positions for patients with lower limb fractures with femur or tibia fractures. When assisting patients in turning over or changing body positions, it can prevent the fracture ends of the fracture from rubbing against each other during turning over or changing body positions by positioning and fixing the fracture of the patient, and play a traction role, replacing the auxiliary role of the patient or medical staff, thereby alleviating the pain of the patient and reducing the labor intensity of the medical staff; Specifically, the fracture patient limb traction device 200 includes an external fixation bracket 210, a traction frame 220, a traction member 230, a driving unit 240 and a connecting member 250; The external fixator 210 is sleeved on the fractured limb of the patient. In this way, the fractured limb of the patient can be fixed to prevent the fractured limb from rubbing against each other when the patient turns over or changes position, thereby alleviating the pain of the patient. The traction frame 220 is connected to the bed frame; the traction member 230 is movably connected to the traction frame 220, and the traction member 230 is located directly above the patient lying on the bed frame, and the traction member 230 is connected to the external fixation bracket 210 through the connecting member 250; the driving unit 240 is connected to the traction member 230; the driving unit 240 is used to drive the traction member 230 to move relative to the traction frame 220, and to retract and release the connecting member 250. Therefore, through the setting of the driving unit 240, the fracture of the patient can be pulled in the process of turning over or changing the position. The traction method can be to pull the fracture vertically or horizontally as the patient's position changes, so as to avoid the patient's own force to change the position, or rely on the medical staff to support the lower limbs for changing position;

[0026] Therefore, the fracture patient limb traction device 200 can play a role in traction and fixation of the patient's lower limb fracture, reduce the mutual friction between the bone ends, and further assist the fracture patient to turn over or change body position, thereby reducing the patient's pain.

[0027] It should be noted that in this embodiment, when configuring the traction member 230 and the driving unit 240, under the action of the driving unit 240, the connecting member 250 connected to the traction member 230 can be retracted and extended, so as to pull and traction the external fixation frame 210 connected to the connecting member 250 in this way, and at the same time, the traction member 230 can also move relative to the traction frame 220 under the driving action of the driving unit 240, so as to always maintain a position directly above the fracture site, so as to maintain the upward traction effect applied to the patient when it is connected to the external fixation through the connecting member 250, so as to lift the fracture site of the patient to achieve the traction effect. In addition, the above-mentioned effect of the traction member 230 can be achieved by controlling the driving unit 240, so that when assisting the patient to turn over or change the body position, the traction effect can be flexibly achieved by controlling the driving unit 240, thereby improving the flexibility of its use.

[0028] For further information, please refer to Figure 1-Figure 8 In this embodiment, when the traction frame 220 is configured, its function is to form a moving track for the traction member 230 during the traction process to meet the traction needs of the patient. Based on this, the traction frame 220 includes a vertical section 221 and an arc section 222 connected to the vertical section 221. One end of the vertical section 221 is provided with a buckle 223 for connecting to the bed frame, and the other end of the vertical section 221 is connected to the arc section 222; wherein the traction member 230 is movably connected to the arc section 222. Such a setting can be conveniently connected to the bed frame through the setting of the vertical section 221, and the arc section 222 can be raised to avoid the traction member 230 from being close to the patient during the movement, thereby interfering with the bedding, railings or other items on the bed, and the setting of the arc section 222 forms a larger traction space directly above the patient to improve the flexibility of traction.

[0029] In order to enable the traction member 230 to move relative to the arc segment 222 under the driving action of the driving unit 240, the arc segment 222 is provided with an arc-shaped rack 224 along its extending direction; The traction member 230 includes a movable frame 231 and a traction gear 232. The movable frame 231 is movably connected to the arc segment 222. The traction gear 232 is rotatably connected to the movable frame 231 and meshes with the arc rack 224. The driving unit 240 includes a first traction motor 241 connected to the movable frame 231 . The first traction motor 241 is in driving connection with the traction gear 232 and is used to drive the traction gear 232 to rotate, so as to drive the movable frame 231 to move relative to the arc segment 222 .

[0030] Thus, in this way, the rotation control of the traction gear 232 can be realized by controlling the operation of the first traction motor 241, thereby driving the traction member 230 to move relative to the arc segment 222 of the traction frame 220. It should be noted that the first traction motor 241 can rotate forward or reverse under the control of the controller, and its rotation speed can also be controlled. Therefore, based on the control of the first traction motor 241, the movement direction of the traction member 230 relative to the traction frame 220 during the traction process and the control of the movement speed can be controlled, thereby improving the flexibility of traction to use the patient's turning over or changing body position.

[0031] In addition, since the patient's lower limbs will be lifted upward during the process of turning over, the present embodiment adapts to the lifting action of the lower limbs and plays a traction role by retracting and extending the connecting member 250 through the driving unit 240. Therefore, the traction member 230 also includes a winding wheel 233 rotatably connected to the movable frame 231; the driving unit 240 also includes a second traction motor 242 connected to the movable frame 231, and the second traction motor 242 is transmission-connected to the winding wheel 233 and is used to drive the winding wheel 233 to rotate to retract and extend the connecting member 250.

[0032] Therefore, through such a setting, during the traction process, the second traction motor 242 can be controlled to realize the retraction and extension of the connecting piece 250, and the speed of its retraction and extension can be controlled, so as to adapt to the change in the vertical height of the patient's lower limbs during the process of turning over or changing the body position, and in the process of the height change, the lower limbs at different heights can be pulled. Therefore, it can replace the patient's own lower limbs in the process of turning over or changing the body position and the auxiliary role of medical staff.

[0033] When configuring the connecting member 250, the connecting member 250 may include a traction rope 251, one end of which is connected to the reel 233, and the other end of which is used to connect to the external fixing bracket 210. Such a configuration can simplify the structure and facilitate traction.

[0034] In addition, since the traction member 230 moves along the arc segment 222 during its activity, the position of its winding wheel 233 will change. Therefore, in order to ensure that the winding wheel 233 can normally retract and release the traction rope 251, the traction member 230 also includes a wire rack 234 connected to the movable frame 231, and the traction rope 251 passes through the wire rack 234 and is connected to the winding wheel 233. This arrangement can ensure that the traction rope 251 can be normally retracted and released.

[0035] In addition, in order to avoid rigid traction and discomfort to the patient during traction, the fracture patient limb traction device 200 further includes a buffer 252, and the traction rope 251 includes a first segment 253 and a second segment 254. The first segment 253 and the second segment 254 are both connected to the buffer 252, and the first segment 253 and the second segment 254 are respectively connected to the reel 233 and the external fixation bracket 210. That is, the buffer 252 can play a buffering role, so that the patient can be slowly stressed during traction or release, thereby improving the comfort during traction.

[0036] Specifically, the buffer member 252 includes a buffer tube 255, a first buffer block 256, a second buffer block 257, and a buffer tension spring 258; the first buffer block 256 and the second buffer block 257 can be movably arranged in the buffer tube 255, the buffer tension spring 258 is arranged between the first buffer block 256 and the second buffer block 257, and the two ends of the buffer tension spring 258 are respectively connected to the first buffer block 256 and the second buffer block 257. Through such an arrangement, the buffer tension spring 258 can play a buffering role, and when the first buffer block 256 and the second buffer block 257 are configured, in the initial position, one of the first buffer block 256 and the second buffer block 257 abuts against the end of the buffer tube 255, or neither of the first buffer block 256 and the second buffer block 257 abuts against the end of the buffer tube 255, that is, there is space for the first buffer block 256 and the second buffer block 257 to increase the distance so as to allow the buffer tension spring 258 to deform.

[0037] For further information, please refer to Figure 1-Figure 8 In this embodiment, the external fixation frame 210 includes a waist fixing frame 211, a waist fixing belt 212, a lower limb fixing frame 213 and a lower limb fixing belt 214; The waist fixing frame 211 is used to be sleeved on the patient's waist and is located on the same side as the patient's fractured limb. The waist fixing belt 212 is used to be wrapped around the patient's waist for at least one circle and is connected to the waist fixing frame 211. The lower limb fixing frame 213 is fixed to the fractured limb of the patient and connected to the waist fixing frame 211 . The lower limb fixing belt 214 is used to wrap around the patient's lower limb for at least one circle and is connected to the lower limb fixing frame 213 .

[0038] Such a setting can fix the patient's waist and lower limb fractures to prevent relative movement of the fractures during traction, thereby improving the stability of traction.

[0039] Moreover, in the process of configuring the above-mentioned waist fixing frame 211 and lower limb fixing frame 213, the lower limb fixing frame 213 is fixedly connected to the waist fixing frame 211 in a detachable manner, and can be adjusted based on actual conditions to choose to install and use one or both of the waist fixing frame 211 and the lower limb fixing frame 213 on the patient.

[0040] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
