Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a lower limb fixation device for patients after cerebrovascular interventional surgery. Background Technology

[0002] Interventional cerebrovascular surgery, with its minimally invasive and highly efficient characteristics, plays a vital role in the treatment of cerebrovascular diseases. Following interventional surgery, patients typically require prolonged bed rest to ensure the stability and recovery of the surgical site. During this period, effective and stable immobilization of the lower limbs not only prevents complications such as deep vein thrombosis but also effectively avoids bleeding or displacement at the surgical site due to limb movement. This ensures the surgical outcome, accelerates postoperative recovery, and improves the overall safety and effectiveness of the treatment.

[0003] Application number CN202321873496.4 discloses a lower limb fixation device for patients after cerebrovascular intervention, including a lower limb fixation component and multiple fixation strap groups. The lower limb fixation component has a strip-shaped receiving groove that can accommodate the patient's lower limb. The strip-shaped receiving groove extends in the front-back direction and its cross-section is U-shaped. Each fixation strap group is sequentially arranged at the opening of the strip-shaped receiving groove along its extension direction. Each fixation strap group includes two fixation straps in corresponding positions. The first ends of the two fixation straps are respectively connected to the two side edges of the lower limb fixation component, and the second ends of the two fixation straps are connected by an adjustable fastening structure. This application effectively fixes the lower limbs of patients after cerebrovascular intervention, effectively ensuring that the limb on the operated side is immobilized and does not flex, thus ensuring patient safety and reducing the workload of medical staff and family members.

[0004] However, existing techniques still have drawbacks: due to the prolonged lower limb immobilization required postoperatively, the patient's legs remain relatively still for extended periods, especially in the later stages of recovery. This can easily lead to muscle stiffness, limited joint movement, and poor blood circulation in the limbs. Therefore, to alleviate the negative effects of prolonged immobilization, patients urgently need appropriate muscle massage and relaxation of the legs to relieve muscle tension, promote blood circulation, thereby improving patient comfort and aiding in functional recovery.

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This utility model relates to a lower limb fixation device for patients after cerebrovascular interventional surgery. Please refer to [link to utility model]. Figures 1 to 7 As shown, this application aims to solve the problems of muscle stiffness, limited joint movement and poor blood circulation caused by prolonged lower limb immobilization in patients after surgery, especially in the later postoperative period, thereby promoting the functional recovery of patients and improving the comfort during treatment.

[0020] In a preferred embodiment, the lower limb fixation device for patients after cerebrovascular intervention consists of four fixation devices 1, which are configured on the bed frame 22. Specifically, two of the four fixation devices 1 are for the thighs, used to support and fix the patient's thighs, and the other two are for the lower legs, used to support and fix the patient's lower legs. On the thigh fixation device 1, a pad 21 is provided on the side away from the lower leg fixation device 1 to expose the thigh puncture site. The pad 21 is designed to support the thigh and avoid applying pressure to the femoral artery puncture area, ensuring that medical staff can easily observe, disinfect, and perform subsequent treatments on the puncture site.

[0021] Each fixing device 1 includes a base 2, with a U-shaped concave surface 3 formed in the center of the base 2. This concave surface 3 is used to support and guide the placement of the patient's lower limbs. The top surfaces 4 on both sides of the base 2, which are connected to the concave surface 3, are used to place the straps 20. Multiple telescopic tubes 5 are arranged in a spaced array along the curvature of the concave surface 3. One end of each telescopic tube 5 is directly exposed on the concave surface 3, serving as the massage end that contacts the patient's lower limbs; the other end passes through the concave surface 3 and extends into the inner cavity of the base 2, where a rotating wheel 6 is rotatably connected. To ensure comfort and skin-friendliness during the massage, a soft silicone head 16 is fitted onto the upper end of each telescopic tube 5. Furthermore, a sleeve 17 is installed on the lower outer periphery of each telescopic tube 5. The upper surface of the sleeve 17 is connected to the upper top surface 4 of the inner cavity of the base 2 by a return spring 18, ensuring that the telescopic tube 5 can quickly and effectively retract to its initial position when not under stress, providing the necessary pre-tension and recovery force for continuous massage movements.

[0022] Inside the cavity of the base 2, a slide rail 19 is arranged along the length of the cavity. The slide rail 19 is located at the bottom of the cavity. At the same time, the cavity of the base 2 is also equipped with a sliding seat 7. The bottom of the sliding seat 7 is provided with a connecting block adapted to the slide rail 19, so that the sliding seat 7 can make smooth reciprocating linear motion in the cavity of the base 2 via the slide rail 19. The top of the sliding seat 7 is designed with a wedge surface 8. The wedge surface 8 is a characteristic structure that enables the horizontal linear motion of the sliding seat 7 to drive the telescopic tube 5 to telescopic motion conversion.

[0023] The motion function of the fixing device 1 is realized by the motion mechanism 9, which is located on one side of the base 2. It includes a reciprocating lead screw 11 driven by a motor 10, and a slider 12 that is threadedly connected to the reciprocating lead screw 11 and driven by it to perform reciprocating linear movement. To ensure the structural stability of the motion mechanism 9, it also includes a first fixing block 13 and a second fixing block 14, which are respectively fixed to both ends of the side wall of the base 2. One end of the reciprocating lead screw 11 is rotatably connected via a bearing seat, and the other end extends parallel to the length direction of the base 2 and passes through the second fixed block 14, coaxially connected to the motor 10 located outside the second fixed block 14. The motion mechanism 9 also integrates a guide rod 15, which is fixed between the first fixed block 13 and the second fixed block 14 and is radially parallel to the reciprocating lead screw 11. The slider 12 is provided with a threaded hole that engages with the reciprocating lead screw 11, and also with a through hole that cooperates with the guide rod 15. The guide rod 15 passes through the through hole and slides with it, which is intended to effectively limit the rotation of the slider 12 and ensure that it only reciprocates linearly along the axial direction of the reciprocating lead screw 11. The slider 12 is fixed to the sliding seat 7 by passing through the side wall of the base 2, thereby transmitting the power of the motion mechanism 9 to the sliding seat 7.

[0024] Working principle: During use, the patient's lower limbs are placed on the concave surface 3 of the U-shape and secured by straps 20 located in the slots 4 on both sides of the top surface of the base 2. During operation, the motion mechanism 9 is activated, and the motor 10 drives the reciprocating screw 11 to rotate, thereby driving the slider 12 to reciprocate axially. Due to the fixed connection between the slider 12 and the sliding seat 7, the sliding seat 7 reciprocates linearly on the slide rail 19 in the inner cavity of the base 2. When the top wedge surface 8 of the sliding seat 7 sequentially abuts against the rotating wheel 6 at the tail end of the array telescopic tube 5 during the reciprocating motion, the telescopic tube 5... Under the action of the wedge 8, the concave surface 3 is pushed out, and its silicone head 16 applies local pressure to the patient's lower limb. When the wedge 8 disengages from the rotating wheel 6, the telescopic tube 5 quickly retracts under the action of the return spring 18. Due to the array arrangement of the telescopic tubes 5 and the sequential contact and disengagement of the wedge 8 and the rotating wheel 6, the telescopic movements of each telescopic tube 5 form a continuous and progressive wave-like sequence of motion, thereby producing a regular, proximal or distal squeezing and relaxing effect on the lower limb muscle tissue, which effectively promotes local blood circulation and lymphatic return, relieves muscle stiffness, and significantly improves patient comfort.
