Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

as shown in fig. 1, the embodiment provides a portable orthopedic traction device, which includes a bed body 1, and two traction mechanisms 3 disposed at two sides of the tail end of the bed body 1; of course, in order to improve the comfort during traction, the head end of the bed body 1 is provided with the back cushion 2.

In this embodiment, as shown in fig. 2, the traction mechanism 3 includes a bracket 31, a slider 32, a traction rope 33, a driving assembly 37, and a limiting member 36.

As shown in fig. 2, the support 31 comprises a vertical column 312 vertically and fixedly mounted on the bed 1, and a cross beam 311 horizontally and fixedly connected to the upper end of the vertical column 312; the columns 312 and beams 311 form an L-shaped structure.

The fixed pulleys 35 are arranged at both ends of the cross beam 311, in other words, the two fixed pulleys 35 are respectively arranged at both ends of the cross beam 311; two fixed pulleys 35 are used for guiding the traction rope 33.

The hauling cable 33 is arranged on the support 31, specifically, the hauling cable 33 is sleeved in the wheel grooves of the two fixed pulleys 35, one end of the hauling cable is connected with a binding sleeve 34 for fixing the leg of a person, the other end of the hauling cable is fixedly connected with the sliding block 32, and the binding sleeve 34 can be an elastic binding sleeve 34.

In this embodiment, the side wall of the upright column 312 is provided with a sliding groove 3121 extending along the length direction of the upright column 312; the sliding block 32 is slidably connected in the sliding groove 3121, so that the sliding block 32 can be displaced along the length direction of the sliding groove 3121. Therefore, the traction rope 33 can be driven to draw through the displacement of the sliding block 32, so that the aim of drawing the legs is fulfilled.

As shown in fig. 3, the driving assembly 37 is disposed on the upright 312, and is mainly used for driving the sliding block 32 to displace, specifically, the driving assembly 37 includes a screw 371 rotatably connected in the sliding groove 3121 and extending along the length direction of the sliding groove 3121, a worm wheel 372 fixedly mounted on the bottom wall of the screw 371, and a worm 373 rotatably connected to the upright 312 and engaged with the worm wheel 372; the slider 32 is screwed to the screw 371.

Through the above arrangement, the worm 373 rotates to drive the worm wheel 372 to rotate, so that the screw rod 371 rotates, and the slider 32 is in threaded connection with the screw rod 371, so that the slider 32 can axially displace along the screw rod 371 along with the rotation of the screw rod 371, and the displacement effect of the slider 32 is driven. It should be noted that, in order to rotate the worm 373, in this embodiment, a hand wheel 374 is fixedly connected to an end of the worm 373. The advantage of pulling the pull cord 33 by driving the displacement of the slider 32 by the screw 371 is that when the screw 371 stops rotating, the slider 32 does not move, in other words, the slider 32 is self-locking, so that the end of the pull cord 33 pulling the leg does not fall freely.

In this embodiment, the limiting member 36 is disposed on the bracket 31 and is used for limiting the sliding of the sliding block 32.

Specifically, as shown in fig. 2, the position-limiting member 36 includes a pin 362 and a blocking rod 361, one end of which is fixedly connected to the sliding block 32, and the other end of which extends to the outside of the sliding block 32; a plurality of jacks 3122 distributed along the height direction of the upright column 312 are disposed on the side wall of the upright column 312 near the stop lever 361, and the bolt 362 is detachably mounted in the jack 3122.

When the bolt 362 is inserted into a certain insertion hole 3122, the end of the bolt 362 exposed outside the insertion hole 3122 may form a shielding portion, and when the blocking rod 361 moves to the position of the bolt 362, the blocking rod 361 cannot move downwards (the blocking rod 361 is above and the bolt 362 is below) under the blocking of the bolt 362, so that the slide block 32 cannot slide downwards continuously, thereby preventing the slide block 32 from driving the traction rope 33 to pull the leg too high, which may cause secondary damage to the leg. The purpose of providing several sockets 3122 is that the latches 362 can be inserted into the corresponding sockets 3122 as required to meet the requirements of different maximum pulling heights.

In this embodiment, the bolt 362 is a bolt, and the insertion hole 3122 is a threaded hole for the bolt to be screwed. When the bolt is used, the bolt is only required to be selected into the threaded hole.

The implementation principle is as follows:

firstly, the pin 362 is inserted into the corresponding insertion hole 3122 according to the maximum pulling height that the leg of the patient can bear, for example, the pulling height that the leg of the patient can bear is higher, the pin 362 can be inserted into the insertion hole 3122 that is lower, then the injured leg of the patient is sleeved into the binding sleeve 34, then the worker starts to rotate the worm 373 to drive the slider 32 to move downward, so that the pulling rope 33 can be pulled up by the slider 32 in the downward moving process, so that the leg of the patient is pulled up, when the slider 32 moves to the pin 362 position, the pin 362 can block the blocking rod 361 so that the blocking rod 361 cannot move downward continuously, which indicates that the worm 373 can be reversed to drive the slider 32 to move upward at the maximum pulling height, and the operation is repeated cyclically, so that the traction rehabilitation treatment for the leg of the patient can be completed.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
