Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

A bridge type movement double lower limb fixator as shown in fig. 1 to 4 comprises a bridge plate 100, the length of which is slightly longer than or as wide as the width of a sickbed, two shoe sleeves 200 are arranged on the bridge plate 100, and feet of a patient extend into the shoe sleeves for fixation when performing bridge type movement. It should be noted that, in order to fix the bridge plate to the tail of the hospital bed conveniently, the clamping assemblies 300 are symmetrically disposed at two ends of the bridge plate 100. Specifically, the clamping assembly 300 includes a threaded sleeve 310 connected to an end of the bridge plate, a threaded rod 320 screwed into the threaded sleeve, the threaded rod extending longitudinally, a turntable 330 coaxially disposed at an upper end of the threaded rod 320 for facilitating rotation of the threaded rod by a medical person, and a clamping plate 340 rotatably connected to the threaded rod 320 disposed at a lower end of the threaded rod. The clamping plates are disposed parallel to the bridge plate 100. When the utility model is fixed, the medical staff rotates the screw to adjust the interval between the clamping plate 340 and the bridge plate, and finally the effect that the bridge plate and the clamping plate are clamped on the upper surface and the lower surface of the sickbed is achieved.

It should be noted that, in order to be the guardrail that clamping assembly can conveniently pass sick bed both sides during the installation, rotatable coupling is between installation assembly 300 and the bridge board. Specifically, a group of rotating shaft seats 110 are respectively arranged at two ends of the bridge plate, and screw sleeves 310 are rotatably connected with the rotating shaft seats, so that when the utility model is required to be fixed on a patient bed, medical staff turns over the clamping assemblies 300 at two ends of the bridge plate 100, and the clamping assemblies and the bridge plate pass through the guardrails in parallel. Preferably, to reduce the space occupied by the storage, the clamping plate 340 includes a base 341 rotatably connected to the screw 320, and a tongue 342 hinged to the base and capable of being turned to be parallel to the bridge plate 100. At the same time, a pallet 343 is provided in the row of brackets, parallel to the bridge plate, and extends below the tongue to support the tongue flipped over to be parallel to the bridge plate 100. When stored, the screw is turned to a state parallel to the bridge plate, and the tongue 342 is turned to a state parallel to the bridge plate, thereby reducing the space required for storage. In order to prevent slipping between the tongue plate and the hospital bed, an anti-slip rubber pad 344 is provided on the upper surface of the tongue plate 342.

In addition, in order to better adapt to patients with different sizes, the position of the boot 200 on the bridge plate 100 can be adjusted. In detail, the bridge plate 100 is provided with an adjusting groove 120 extending along the length direction of the bridge plate, and a slider 400 is slidably provided in the adjusting groove, and is fixedly connected with the shoe 200. Meanwhile, a positioning mechanism 500 capable of fixing the slider in the chute is provided in the slider. Specifically, the slider has a cavity 410 and a slide 420 in communication with the cavity. Wherein the slideway is arranged in a penetrating way and is opposite to the groove wall of the adjusting groove 120. The positioning mechanism comprises a cam 510 arranged in the cavity 410, and the rim of the cam is in transmission connection with a T-shaped shaft 520 which is rotatably inserted in the sliding block. The medical staff rotates the T-shaped shaft to drive the rotating shaft in the cavity to rotate. In addition, a positioning pin 530 is slidably inserted into the slide 420, the tip end of the positioning pin faces the outer groove wall, a spring 540 is sleeved on the other end of the positioning pin, and the positioning pin abuts against the rim of the cam under the action of the spring. It should be noted that, in order to enhance the locking effect of the positioning pin, a plurality of tooth-shaped grooves 130 are uniformly distributed on the groove wall of the adjusting groove 120, and when the positioning pin is driven by the cam 510 to extend out of the slideway, the tip of the positioning pin is clamped into the tooth-shaped grooves.
