Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary technology, and in particular to an adjustable lower limb care restraint and fixation device. Background Technology
[0002] Neurosurgery is a branch of surgery that treats diseases of the brain and spinal cord caused by trauma. Agitation, coma, and delirium are common symptoms in neurosurgery. There are many factors that cause agitation. To ensure the effectiveness of treatment, restraint devices are often used to protect the patient's limbs.
[0003] Utility model patent CN219516752U discloses a lower limb care restraint and fixation device for neurosurgery, including a support base. The support base includes a left support base and a right support base symmetrically arranged, with an adjustment component between the left and right support bases. A support plate is fixedly connected to the left support base, a connecting plate is fixedly connected to the support plate, and a fixing plate is fixedly connected to the connecting plate. A restraint strap is provided on the fixing plate. A rotating shaft is fixedly connected to the support base, and a fixed arc-shaped plate that cooperates with the support plate is rotatably connected to the rotating shaft. This invention solves the problems of existing lower limb care restraint and fixation devices for neurosurgery, which cannot be adjusted according to the patient's body shape and have a rigid fixation method that increases patient resistance.
[0004] However, the aforementioned existing technology has the following problems:
[0005] While the lower limb care restraint device for neurosurgery of CN219516752U can be adjusted according to the patient's body shape, it does not restrict the rotation angle of the left threaded rods on both sides. Therefore, the patient can still make a certain degree of leg kicking posture. In addition, the lower limb care restraint device for neurosurgery of CN219516752U needs to be tied to the bed board through the third restraint strap, which is relatively difficult to fix.

[0037] Example
[0038] like Figure 1-5 As shown, this embodiment provides an adjustable lower limb care restraint and fixation device, which includes a support plate 1, a fixing plate 2, a connecting plate 3, an adjustment box 4, and a claw 6.
[0039] The left and right ends of the adjustment box 4 are respectively hinged to the two connecting plates 3; the front and rear ends of the two connecting plates 3 are fixedly provided with support plates 1, and the two connecting plates 3 are hinged to the rear end of the side away from each other with fixing plates 2. The two fixing plates 2 are fixedly provided with claws 6 on one side. The upper end of the two fixing plates 2 is provided with L-shaped grooves 10 on both sides near the front end, that is, a total of four L-shaped grooves 10 are provided.
[0040] The rotating surface of the hinged adjustment box 4 and the connecting plate 3 is parallel to the rotating surface of the hinged connecting plate 3 and the fixed plate 2.
[0041] Specifically, the connecting plate 3 can connect two support plates 1 located on the same side, which can fix the rotation angle of the patient's lower leg and thigh, and the adjusting mechanism 8 can adjust the distance between the fixing plates 2 on both sides and the bed rails on both sides, so that the device can be fixed to the bed rails by the claws 6, and the two fixing plates 2 can be stored by the fixing mechanism 9 in the L-shaped groove 10, which facilitates the transfer of the patient.
[0042] Each of the four L-shaped grooves 10 is connected to a fixing mechanism 9. Each of the four fixing mechanisms 9 includes an insert 901, an L-shaped plate 902, and a spring 903. One end of each of the four springs 903 is fixedly disposed on one side of the inner wall of the four L-shaped grooves 10, and the other end of each of the four springs 903 is fixedly connected to the four L-shaped plates 902. Each of the four inserts 901 is fixedly disposed at the center of the lower end of one side of each of the four L-shaped plates 902, and the four inserts 901 are disposed on the outside of the L-shaped grooves 10.
[0043] The two connecting plates 3 are provided with sliding grooves 5 at the center of one side away from each other and near the front and rear ends. Among the four sliding grooves 5, the two sliding grooves 5 located on the same connecting plate 3 are provided with grooves 7 at the center of one side away from each other on their inner walls.
[0044] Specifically, by embedding the insert 901 inside the groove 7, the rotation angle of the two fixed plates 2 can be limited.
[0045] When the fixed plate 2 is in the storage state, one end of each of the four L-shaped plates 902 is slidably disposed inside the four sliding grooves 5, and the four inserts 901 are respectively embedded inside the four inserts 7.
[0046] The adjustment box 4 includes an adjustment mechanism 8. The left and right end faces of the adjustment box 4 are respectively hinged to two connecting plates 3 through the adjustment mechanism 8. One end of the adjustment mechanism 8 is located inside the main body of the adjustment box 4, and the other end of the adjustment mechanism 8 extends out of the main body of the adjustment box 4. The adjustment mechanism 8 includes two threaded rods 801, two longitudinal bevel gears 802, a transverse bevel gear 803, and two extension rods 804. Limiting plates 11 are fixedly provided on both sides of the inner wall of the main body of the adjustment box 4.
[0047] Two threaded rods 801 are rotatably mounted at the center of opposite sides of two limiting plates 11. Two longitudinal bevel gears 802 are fixedly mounted at the opposite sides of two threaded rods 801. A transverse bevel gear 803 is rotatably mounted at the center of the upper end face of the inner wall of the main body of the adjusting box 4 and meshes with the two longitudinal bevel gears 802. Two extension rods 804 are slidably mounted on both sides of the inner wall of the main body of the adjusting box 4. Two extension rods 804 are hinged at the center of opposite sides of two connecting plates 3. Slide grooves 12 are provided at both ends of the outer wall of the two extension rods 804. Two limiting plates 11 are slidably mounted inside the two extension rods 804 through the two slide grooves 12. The limiting plates 11 are connected to the inner wall of the main body of the adjusting box 4 and restrict the rotation of the extension rods 804 through the slide grooves 12. The lower end of the rotating shaft 401 is fixedly connected to the transverse bevel gear 803, and the upper end of the rotating shaft 401 extends through the outer wall of the adjusting box 4 to facilitate the rotation of the transverse bevel gear 803.
[0048] Specifically, the limiting plate 11 and the slide groove 12 can effectively restrict the rotation of the extension rod 804, ensuring that the rotation angles of the two connecting plates 3 are always consistent.
[0049] Specifically, rotating the transverse bevel gear 803 drives the two longitudinal bevel gears 802 to rotate, thereby causing the two longitudinal bevel gears 802 to drive the two threaded rods 801 to rotate, so that the two threaded rods 801 can drive the two extension rods 804 to move respectively.
[0050] Specifically, by rotating the two threaded rods 801, the two extension rods 804 can be driven to rotate on the outer walls of the two threaded rods 801 respectively.
[0051] The inner walls of the two extension rods 804 are provided with threads in opposite directions, and the two extension rods 804 are respectively threadedly sleeved on the outer walls of the two threaded rods 801.
[0052] Each of the four support plates 1 has a restraint strap hinged at the center of one side, and a buckle hinged at the center of the other side of each of the four support plates 1. The restraint straps and buckles are connected to secure the patient's leg to the support plate 1.
[0053] Specifically, the restraint straps and buckles can fix the patient's lower limbs through four support plates 1, and at the same time connect two support plates 1 on the same side through two connecting plates 3, thereby restricting the rotation of the patient's lower leg.
[0054] The working principle of the above-mentioned adjustable lower limb care restraint and fixation device:
[0055] The patient's legs are placed on two support plates 1 on the same side. The patient's legs are then connected and fixed to the support plates 1 by restraint straps and buckles. The two extension rods 804 are driven to move laterally by rotating the pivot 401 and rotating the transverse bevel gear 803, thereby adjusting the distance between the two fixed plates 2 and the bed rail. The rotation of the extension rods 804 is restricted by the limiting plate 11, which can prevent the patient's legs from kicking. It is also convenient to connect the device to the bed rail by the two claws 6, which can further improve the fixation effect of the device. At the same time, the hinged setting between the two extension rods 804 and the two fixed plates 2 can facilitate the patient to adjust the leg position. After adjustment, the two claws 6 can be rotated to engage with the bed rail at different positions, thereby achieving the fixation effect for the legs of patients with different body types.
[0056] When a patient needs to be transferred, the claw 6 is separated from the bed rail. The two L-shaped plates 902 on the same fixed plate 2 can be pulled towards the center. Then, the fixed plate 2 is rotated until it is close to the connecting plate 3, so that one end of the two L-shaped plates 902 is slidably set in the two sliding grooves 5 respectively. Then, the hand is released so that the insert 901 is embedded in the groove 7 under the action of the spring 903 to fix the rotation angle of the fixed plate 2. The fixed plate 2 is in the storage state, thereby achieving the effect of fixing the rotation angle of the fixed plate 2, which facilitates the transfer of the patient.
[0057] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
