[0048] Continue to refer to Figure 1 , the automatic lifting structure 103 further includes a controller 1035. The controller 1035 is located outside the fixed frame 1031. An up button 10351 and a down button 10352 are provided on the controller 1035. The controller 1035 is controllably connected to the motor 1033. The up button 10351 and the down button 10352 on the controller 1035 are set to respectively control the output end of the motor 1033 to rotate forward and reverse when pressed. When adjusting the height according to the surgical needs, press the up button 10351 or the down button 10352, and the controller 1035 controls the output end of the motor 1033 to rotate. The motor 1033 drives the screw rod 1034 to push the slider 1032 to slide on the guide rail through the threaded hole, realizing the adjustment of the height of the upper frame body 102 connected to the slider 1032, and further realizing the adjustment of the overall height of the frame body 100.

[0049] See Figure 5 and 6, a clamping member 104 is provided on the frame main body 100. The height of the clamping member 104 on the frame main body 100 is adjustable. The clamping member 104 is detachably connected to the edge of the bed body. Specifically, a rotating sleeve 1041 is provided on the outer side of the clamping member 104. The rotating sleeve 1041 is sleeved on the outer side of the frame main body 100. A bolt is radially installed on the rotating sleeve 1041, and the bolt abuts and cooperates with the outer side of the frame main body 100;

[0050] The clamping member 104 is "C"-shaped, that is, a receiving area for the edge of the bed body is provided on one side of the clamping member 104. A bolt is provided on one side of the clamping member 104 in the height direction of the bed body. The bolt is arranged along the height direction of the bed body, and a plurality of bolts are arranged in the length direction of the edge of the bed body. When in use, the clamping member 104 can be first moved along the frame main body 100 to a suitable height through the rotating sleeve 1041, and the bolt on the rotating sleeve 1041 is rotated. The bolt presses the outer wall of the frame main body 100 to fix the height of the clamping member 104. The receiving area on the clamping member 104 is sleeved on the edge of the bed body, and the bolt on the clamping member 104 is further rotated. The bolt presses the edge of the bed body to fix the relative position of the clamping member 104 and the bed body.

[0051] Further, referring to Figure 5 , the frame main body 100 can rotate around its own axis through the clamping member 104. Specifically, the rotating sleeve 1041 is rotatably installed on the outer side of the clamping member 104. The rotating sleeve 1041 and the frame main body 100 are coaxially arranged. A first bevel gear is provided on the outer side of the rotating sleeve 1041. An adjusting knob 1042 is rotatably connected to the clamping member 104, and a second bevel gear matching the first bevel gear is provided on the adjusting knob 1042. When in use, the clamping member 104 can be first fixed to the edge of the bed body, and the rotating sleeve 1041 is fixed to the outer side of the frame main body 100. The adjusting knob 1042 is rotated. The adjusting knob 1042 drives the rotating sleeve 1041 to rotate through the bevel gear, and then drives the entire frame main body 100 to rotate.

[0052] To improve the installation stability of this shoulder joint surgical traction frame and facilitate its flexible transfer indoors, referring to Figure 8 , further, a base 105 with universal wheels is provided at the bottom of the frame main body 100. Specifically, the base 105 is a five-star foot base 105, and a universal wheel is provided at each foot of the five-star base 105.

[0053] Referring to Figure 1 and 7, the length adjusting member 500 and the height adjusting member 400 share an adjusting housing 800. The adjusting housing 800 is movably sleeved on the outside of the frame main body 100 along the length direction. The height adjusting member 400 is movably connected to the adjusting housing 800 in a direction perpendicular to the frame main body 100. An elastic member 401 is arranged between the height adjusting member 400 and the adjusting housing 800. An active latch 402 is arranged on the height adjusting member 400. Positioning portions 403 matching the active latch 402 are arranged at intervals along the length direction on the frame main body 100. The elastic member 401 is arranged to provide a force towards the frame main body 100 for the height adjusting member 400, so that the active latch 402 contacts the positioning portion 403. Specifically, a groove-shaped positioning portion 403 is formed by inward depression on the outside of the frame main body 100. A holding hole is formed in the adjusting housing 800. The height adjusting member 400 is movably installed inside the holding hole. The height adjusting member 400 is a frame structure corresponding to the inner circumference of the holding hole. Further, a groove corresponding to the finger is arranged inside the height adjusting member 400, so that the height adjusting member 400 conforms to ergonomics and is convenient for operation. During use, the operator inserts the hand into the inside of the height adjusting member 400 and presses. The active latch 402 on the height adjusting member 400 and the positioning portion 403 are separated. The adjusting housing 800 is adjusted to a suitable height. The height adjusting member 400 is released. The elastic member 401 pushes the height adjusting member 400 to reset. The active latch 402 is inserted into the corresponding positioning portion 403, realizing the adjustment of the height of the height adjusting member 400. During the height adjustment of the height adjusting member 400, the cross bar 200 swings under the support of the connecting rod 300. See Figure 1 and 2 , realizing the extension and retraction of the lower cuff 600. If the height adjusting member 400 is moved below the frame main body 100, the cross bar 200 can be retracted, reducing the occupied space of the device in the horizontal direction.

[0054] See Figure 9 , the length adjusting member 500 includes two handles 501 respectively rotatably connected to opposite sides of the adjusting housing 800. The handles 501 are divided into a proximal handle and a distal handle. The proximal handle is connected to the traction rope 202 connecting the proximal pulley 2011. The distal handle is connected to the traction rope 202 connecting the distal pulley 2012. During use, the corresponding handle 501 can be rotated to realize the adjustment of the length of the traction rope 202, and further realize the adjustment of the traction force and angle. Further, a lock is arranged on the adjusting housing 800. The lock is arranged to fix the position of the handle 501 on the adjusting housing 800 to fix the length of the traction rope 202 after adjustment.

[0055] Further, the cross bar 200 is provided as hollow, and the towing ropes 202 between the length adjusting member 500 and the proximal pulley 2011, and the towing ropes 202 between the length adjusting member 500 and the distal pulley 2012 are all hidden inside the cross bar 200. Even further, two independent pipes are provided inside the cross bar 200, and the two independent pipes are respectively used to accommodate the towing ropes 202 between the length adjusting member 500 and the proximal pulley 2011 and the towing ropes 202 between the length adjusting member 500 and the distal pulley 2012. Through the above limitations, a moving space for the towing ropes 202 is reserved inside the cross bar 200 to prevent the towing ropes 202 from jamming during the process of being guided by the pulleys.

[0056] See Figure 1 and 2 , the traction state monitoring member 700 includes a liquid crystal display screen provided on the adjustment housing 800. The liquid crystal display screen can display the traction force and angle. Specifically, sensors capable of acquiring the traction force and angle are provided on the towing rope 202 and the sleeve 600. The sensors are electrically connected to the liquid crystal display screen. The traction state monitoring member 700 realizes the display of the traction angle and force, facilitating the real-time observation and recording of key parameters to ensure the standardization and safety of the operation.

[0057] Continue to see Figure 1 , the position of the proximal pulley 2011 on the cross bar 200 is adjustable. Specifically, a proximal sleeve is sleeved outside the cross bar 200. The proximal sleeve is arranged to be suitable for moving along the length direction of the cross bar 200. A bolt is arranged radially on the proximal sleeve, and the bolt is in abutting cooperation with the outside of the cross bar 200. During use, the proximal pulley 2011 can move on the cross bar 200 through the proximal sleeve to adjust the position of the proximal pulley 2011 on the cross bar 200. Further rotate the bolt, and the end of the bolt abuts against the outside of the cross bar 200 to realize the fixation of the relative position of the proximal pulley 2011 on the cross bar 200.

[0058] A multi-functional fixing and traction accessory is provided at the end of the towing rope 202 to adapt to various types of suspenders, straps and rotating hooks to meet the requirements of different body types and different surgical procedures.

[0059] Further, the shoulder joint surgical traction frame further includes a reminder module. The reminder module is provided on the frame main body 100. The reminder module is arranged to be suitable for sending a reminder every 0.5 hours after 2 hours of the start of traction. By adding a reminder module with a traction time reminder function, it is possible to prevent brachial plexus nerve injury caused by too long traction time.

[0060] In summary, by defining the position of the crossbar 200 on the frame main body 100, both the crossbar 200 and the connecting rod 300 are arranged on the same side of the frame main body 100. On the premise of ensuring the overall load-bearing capacity and stability, the occupation of the space outside the bed body is reduced. In cooperation with the length adjusting member 500, the height adjusting member 400 and the rotating sleeve 1041, multi-directional adjustment of the sleeve 600 can be achieved, improving the applicability and operation convenience;

[0061] By adjusting the length of the traction rope 202 between the pulley 201 and the sleeve 600 through the length adjusting member 500, precise adjustment of the traction force and angle can be achieved;

[0062] An automatically lifting structure 103 driven by electricity is arranged on the frame main body 100 to achieve automatic fine adjustment of the traction height, reduce manual intervention, and improve the accuracy and efficiency;

[0063] A traction state monitoring member 700 capable of displaying the traction force and angle is provided, which can real-time display the traction force received by the patient's arm and the specific angle of the limb being tractioned, facilitating both the operator's operation and real-time monitoring, recording and traceability.
