Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a traction frame. Background Art

[0002] The lower limb traction frame is mainly used for traction, fixation and support of the lower limbs. The use of the lower limb traction frame can effectively restore the physiological curvature of the lower limbs, promote fracture healing and joint reduction. In addition, the lower limb traction frame can also be used for postoperative rehabilitation treatment, such as postoperative muscle relaxation and recovery. During rehabilitation treatment, patients can use the lower limb traction frame to perform active or passive muscle movements to promote muscle recovery and functional reconstruction.

[0003] At present, during the traction process, the patient places the lower limbs on a support, and then the lower limbs are pulled by a traction device. Medical staff can gradually adjust the traction force through an adjustment device on the traction frame. However, the adjustment device on the traction frame is mainly adjusted by adding or reducing counterweights. The operation steps are cumbersome, which increases the workload of medical staff.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The embodiments of the present application solve the problems in the prior art by providing a traction frame.

[0023] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0024] Embodiment 1:

[0025] The specific structure of this embodiment is as follows: Figure 1-Figure 2 As shown, a traction frame comprises:

[0026] A connecting plate 8, four first supporting legs 9 are connected to the bottom of the connecting plate 8, a second supporting leg 10 and a third supporting leg 21 are connected to the top of the connecting plate 8, a bracket 1 is connected to the top of the second supporting leg 10 and the third supporting leg 21, the bracket 1 is placed on the bed, the patient places the lower limbs on the bracket 1, and the ankles of the lower limbs are fixed by the restraint belt 2, and then the driving structure completes the traction work of the patient's lower limbs;

[0027] A pulley bracket 4 is connected to the upper part of the connecting plate 8 near the third supporting foot 21, and the inner side of the pulley bracket 4 is rotatably connected with the first pulley 5 and the second pulley 7 from top to bottom respectively, and the outer sides of the first pulley 5 and the second pulley 7 are slidably connected with a traction rope 6, one end of the traction rope 6 is connected with a restraining belt 2, and the other end of the restraining belt 2 is connected with a hanging ring 14, and the outer side of the hanging ring 14 is connected with a dynamometer 12, and the outer side of the dynamometer 12 is movably connected with a positioning frame 20, and a driving mechanism is provided on the outer side of the positioning frame 20. The patient places the lower limbs on the bracket 1, and puts the restraining belt 2 on the patient's ankle, and puts the restraining belt 2 on the patient's ankle, and sticks the Velcro fur surface 13 on the inner side of the restraining belt 2 on the Velcro smooth surface 3 to complete the fixation of the patient's ankle.

[0028] In some examples, the driving mechanism includes a pair of motors 18 connected above the connecting plate 8, one end of the output shaft of the motor 18 is connected to a reciprocating screw 17, the end of the reciprocating screw 17 is connected to a bearing seat 15, the bearing seat 15 is fixedly connected to the connecting plate 8, the outer side of the reciprocating screw 17 is connected to a ball nut 16, the outer side of the ball nut 16 is connected to a fixing plate 19, one side of the fixing plate 19 is fixedly connected to a positioning frame 20, the motor 18 is turned on, the reciprocating screw 17 is driven to rotate, and the ball nut 16 and the fixing plate 19 on its outer side are driven to move backward, thereby driving the dynamometer 12 to move backward, and under the connection of the traction rope 6, the traction restraint belt 2 moves backward, thereby completing the traction of the patient's lower limbs.

[0029] In some examples, the position of the second pulley 7 corresponds to the position of the dynamometer 12 , and the position of the first pulley 5 corresponds to the position of the bracket 1 .

[0030] In some examples, the third support leg 21 is set to a U-shape, and one end of the traction rope 6 passes through the interior of the third support leg 21. When the driving mechanism drives the dynamometer 12 to move backward, the traction restraint belt 2 moves backward under the connection action of the traction rope 6. By setting the third support leg 21 to a U-shape, the traction rope 6 can move forward and backward conveniently.

[0032] In some examples, a shell 11 is connected above the driving mechanism, and the end of the shell 11 is fixedly connected to the connecting plate 8. By providing the shell 11, it is not easy for the patient to contact the driving mechanism during use, thereby achieving a protective effect.

[0033] In some examples, the housing 11 is set to be L-shaped, and the reciprocating screw 17 drives the fixed plate 19 to move left and right during the rotation. By setting the housing 11 to be L-shaped, it is not easy for the patient to contact the driving mechanism during use, which has a protective effect, and it is convenient for the fixed plate 19 to move left and right without being restricted.

[0034] By adopting the above technical solution:

[0035] The patient places the lower limbs on the bracket 1 and fixes the ankles of the lower limbs with the restraint belt 2, then turns on the motors 18 on both sides to drive the reciprocating screw 17 to rotate, thereby driving the ball nut 16 to move backward, and under the connection action of the fixing plate 19, drives the positioning frame 20 and the dynamometer 12 inside it to move backward, and under the connection action of the traction rope 6, the traction restraint belt 2 moves backward, thereby completing the traction of the patient's lower limbs. The operation steps are simple, eliminating the step of manually adjusting the counterweight block. At the same time, medical staff can observe the traction force by observing the dynamometer 12, which is convenient for recording.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
