Embodiment
[0020] As Figures 1-3 shown, an adjustable traction device for orthopedic surgery includes a trolley 1 and a counterweight 19. The top end of the trolley 1 is fixedly connected with a support frame 2. One end of the support frame 2 is fixedly connected with a slide rail 3. The outer side of the slide rail 3 is slidably connected with a slider 4. The slider 4 can be removed from the outer side of the slide rail 3, and then the slider 4 can be engaged with the rail on the side of the hospital bed, so that the device can be fixed for use beside the bed. One end of the slider 4 is fixedly connected with a sleeve 5. The inner side of the sleeve 5 is slidably connected with a support pipe 6. The top end of the support pipe 6 is rotatably connected with a cross pipe 20. The second pull rope 21 passes through the inner sides of both the cross pipe 20 and the support pipe 6. Both ends of the second pull rope 21 are fixedly connected with second hooks 22. The second hooks 22 are used to hang on the arm sleeve on the outer side of the patient's arm. One end of the support pipe 6 is fixedly connected with a fixed column 7. The other end of the fixed column 7 is fixedly connected with an adjusting mechanism. The counterweight 19 is hung on the second hook 22 at the bottom, and the weight of the counterweight 19 can be selected according to actual needs.
[0021] As a further improvement of the present utility model, as Figure 1 , Figure 2 and Figure 3As shown in the figure, the adjusting mechanism includes a fixing ring 8 fixedly connected to the fixing column 7. A turntable 9 is rotatably connected to the inner side of the fixing ring 8. A limiting component is arranged on the inner side of the turntable 9, and one end of the limiting component is engaged with the fixing ring 8. One end of the turntable 9 is fixedly connected to a connecting cylinder 14. A square tube 15 is slidably connected to the inner side of the connecting cylinder 14. A first pull rope 17 passes through the inner sides of both the square tube 15 and the connecting cylinder 14. Both ends of the first pull rope 17 are fixedly connected to a first hook 18. A counterweight 19 can also be hung on the outer side of the first hook 18. By the mutual rotation between the fixing ring 8 and the turntable 9 and the mutual movement between the connecting cylinder 14 and the square tube 15, the adjustment of the traction angle and height of the arm can be realized. Then, the second hook 22 can be hung on the cuff. This device can realize the adjustment of the angle and height of the patient's arm through two steps, simplifying the adjustment steps and facilitating the use of medical staff.
[0022] As a further improvement of the present utility model, as Figure 3 shown, the limiting component includes a guiding plate 10 fixedly connected to the turntable 9. A guiding rod 11 is slidably connected to the inner side of the guiding plate 10. The other end of the guiding rod 11 is fixedly connected to a clamping head 13, and the clamping head 13 is engaged with the fixing ring 8. A spring 12 is arranged on the outer side of the guiding rod 11, and both ends of the spring 12 are fixedly connected to the guiding plate 10 and the clamping head 13 respectively. The spring 12 gives a elastic force to the clamping head 13. After the turntable 9 is adjusted to a suitable position, the turntable 9 can be limited and fixed under the action of the mutual engagement between the clamping head 13 and the fixing ring 8, without manual fixing, and the fixing of the turntable 9 can be realized at any time, facilitating the use of medical staff.
[0023] As a further improvement of the present utility model, as Figure 3 shown, slots engaged with the clamping head 13 are formed in the four circumferences of the inner wall of the fixing ring 8. The slots facilitate the quick engagement between the fixing ring 8 and the clamping head.
[0024] As a further improvement of the present utility model, as Figure 1 、 Figure 2 shown, a locking screw 16 is spirally connected to the inner side of one end of the connecting cylinder 14, and the locking screw 16 is in close fit with the square tube 15. After the square tube 15 and the connecting cylinder 14 are adjusted to a suitable position, the square tube 15 can be limited and fixed by the locking screw 16.
[0025] Workflow: When traction needs to be applied to the patient's arm, fix the cuff on the outside of the patient's arm. Then, hang the counterweight 19 on the outside of the first hook 18 at the bottom. Next, hang the first hook 18 together with the cuff. Then, the staff rotates the turntable 9 through the connecting tube 14 inside the fixed ring 8, causing the connecting tube 14 to drive the square tube 15 to rotate to a suitable position. At the same time, the spring 12 also drives the chuck 13 to engage with the fixed ring 8, and the chuck 13 is used to limit and fix the position between the turntable 9 and the fixed ring 8. Then, the first pull rope 17 can be pulled, causing the first pull rope 17 to drive the arm to rotate to a suitable angle and height through the first hook 18 and the cuff. If the height and angle of the arm rotation do not meet the requirements, the medical staff can adjust the position between the connecting tube 14 and the square tube 15 to change the traction height and angle of the first pull rope 17, so as to meet different usage requirements. Then, the staff hangs the second hook 22 on the part of the cuff near the armpit, thus completing the traction of the arm.
