[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0028] The present utility model provides a Figure 1 high-stability Thomas traction frame as shown in the figure, including a traction frame body 1 located on the hospital bed and a traction rope 5. One end of the traction rope 5 is connected to the traction bow. A cloth sleeve 4 for supporting the affected limb is sleeved on the traction frame body 1. Two columns of the traction frame body 1 are located on one side of the cloth sleeve 4. A fixed guide wheel 2 is fixed on one side of the column, and a rotatable adjustable guide wheel assembly 3 is provided at the top of the column. The other end of the traction rope 5 passes between the adjustable guide wheel assembly 3 and the fixed guide wheel 2 and is suspended at the end of the hospital bed.

[0029] When the present utility model is in use, first, the traction frame body 1 is fixed on the hospital bed through the reinforcement assembly 8. Specifically, as Figure 2 shown, the reinforcement assembly 8 includes a column binding strap 81 and a base binding strap 82. The column binding strap 81 is installed on the column of the traction frame body 1. The column binding strap 81 is located below one side of the column. The column binding strap 81 binds the column of the traction frame body 1 to the end of the hospital bed. The base binding strap 82 is fixed to the chassis of the traction frame body 1. The base binding strap 82 is located at the bottom of the cloth sleeve 4. The base binding strap 82 binds the chassis of the traction frame body 1 to the bed board of the hospital bed. Moreover, both the column binding strap 81 and the base binding strap 82 in the present utility model are adjusted in length through a Japanese character buckle. During use, the lengths of the column binding strap 81 and the base binding strap 82 can be shortened as much as possible, so that the chassis of the traction frame body 1 can be closely attached to the bed board of the hospital bed, and the column of the traction frame body 1 can be closely attached to the end of the hospital bed, so as to prevent the traction frame body 1 from shaking during use and affecting the traction effect on the affected limb, and improve the stability of the present utility model during use;

[0030] As Figure 3As shown in the figure, the adjustable guide wheel assembly 3 in the present utility model includes two connecting plates 31 that are in contact with the inner sides of the tops of the two columns of the traction frame body 1. Two guide wheel fixing frames 32 are fixed between the two connecting plates 31. The included angle between the two guide wheel fixing frames 32 is 90°. An adjustable guide wheel 33 for guiding the traction rope 5 is rotatably connected inside each guide wheel fixing frame 32. One end of the traction rope 5 is connected to the traction bow, and the other end passes through the adjustable guide wheel 33 and the fixed guide wheel 2 as needed, and then is hung at the end of the hospital bed;

[0031] Next, adjust the traction direction. The connecting plate 31 is rotatably connected to the top of the column of the traction frame body 1 through a rotating shaft 34. The rotating shaft 34 is fixed to the connecting plate 31. A locking disc 35 is fixed to the end of the rotating shaft 34 away from the connecting plate 31. The locking disc 35 is in contact with the side of the top of the column of the traction frame body 1 away from the guide wheel fixing frame 32. A handle 39 for a medical staff to rotate the locking disc 35 by hand is fixed to the side of the locking disc 35 away from the rotating shaft 34. Before use, the medical staff pinches the handle 39 with their hand and then rotates the locking disc 35 to drive the guide wheel fixing frame 32 and the adjustable guide wheel 33 to rotate. It is also possible to directly hold the guide wheel fixing frame 32 by hand and rotate it. The specific operation method can be flexibly adjusted according to the on-site situation;

[0032] A plurality of through holes 37 are provided in the locking disc 35, and a plurality of threaded holes 38 are provided on the side of the top of the column of the traction frame body 1. A bolt 36 is provided on the side of the locking disc 35 away from the guide wheel fixing frame 32. One end of the bolt 36 passes through the through hole 37 and extends into the threaded hole 38 to be threadedly connected with the threaded hole 38. After adjusting the positions of the guide wheel fixing frame 32 and the adjustable guide wheel 33, the bolt 36 can be inserted into the connected through hole 37 and threaded hole 38 and tightened to fix the two guide wheel fixing frames 32 between the two columns of the traction frame body 1.

[0033] Then, adjust the magnitude of the traction force. As shown in FIGS. Figure 1 、 4 and 5, a plurality of weights 7 are installed at the other end of the traction rope 5 through a weight fixing assembly 6. By selecting weights 7 of different numbers and different weights, different magnitudes of traction force can be applied to the affected limb through the traction rope 5;

[0034] In order to prevent the weights 7 from falling off due to the movement of people around the hospital bed, the weight fixing assembly 6 in the present utility model includes a connecting frame 61 fixed to the other end of the traction rope 5. Different from the traditional horizontal placement of the weights 7, the weights 7 in the present utility model are stuck to the outer end of the connecting frame 61 in a downward-opening shape. Under the action of the self-gravity of the weights 7, the opening can be stuck to the outer end of the connecting frame 61. Compared with the traditional horizontal placement of the opening of the weights 7, the downward-opening method in the present utility model is less likely to fall off;

[0035] Moreover, two fixed disks 62 are fixed to the outer end of the connecting frame 61. An elastic limiting strip 65 is fixed between the two fixed disks 62, and a round rod 66 is fixed between the two fixed disks 62. The elastic limiting strip 65 is fixed to the outer end of the round rod 66. The cross-section of the elastic limiting strip 65 is in the shape of a circle at the top and a rectangle at the bottom. The width of the bottom end of the elastic limiting strip 65 is the same as the opening width of the weight 7, and the width of the bottom end of the elastic limiting strip 65 is smaller than the diameter of the top end of the elastic limiting strip 65. Therefore, the upper part of the elastic limiting strip 65 can be tightly inserted into the opening of the weight 7 to block the opening of the weight 7 and fix the weight 7 to the outer end of the connecting frame 61, achieving the effect of preventing detachment.

[0036] Furthermore, springs 63 are fixed to one side of each of the two fixed disks 62 close to the weight 7. One end of each spring 63 is fixed with a moving disk 64. The two springs 63 respectively push the two moving disks 64 to squeeze on both sides of the weight 7. The more weights 7 inserted between the two moving disks 64, the greater the squeezing force exerted by the springs 63 on both sides of the weight 7. Thus, the weight 7 can be further strengthened to prevent it from falling off the connecting frame 61, improving the stability and safety during use of the present utility model.

[0037] Moreover, the weight 7 in the present utility model is located at the end of the hospital bed, which can also facilitate medical staff to increase or decrease the weight 7 at any time to adjust the traction force and reduce the operation difficulty.

[0038] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
