Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary treatment, in particular to a lower limb joint visualization interventional treatment operation support. Background Art

[0002] At present, when placing the patient in visual interventional treatment of the lower limbs, single or comprehensive fixation aids such as ordinary sheets, soft pillows, elastic bands, and restraints are generally used for restriction. However, none of them can achieve the standard position fixation guided by B-ultrasound visualization of the lower limb joints, affecting the safety and accuracy of the treatment, and the patient's physical sensation is poor. Utility Model Content

[0003] The purpose of the utility model is to provide a lower limb joint visualization interventional treatment operation support to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a lower limb joint visualization interventional treatment operation support, comprising: a support frame; a telescopic frame, wherein there are two telescopic frames, one end of the first telescopic frame is rotatably mounted on the support frame, the other end of the first telescopic frame is rotatably connected to one end of the second telescopic frame, and the other end of the second telescopic frame is rotatably mounted with a slider, and the slider is slidably mounted on the support frame; a foot rest, wherein the foot rest is mounted on one end of the second telescopic frame away from the first telescopic frame; a first fixing member, wherein the first fixing member is mounted on the support frame, and the first fixing member is used to relatively fix the slider and the support frame.

[0005] This technical solution has at least the following beneficial effects: the patient's lower limbs are placed on top of two telescopic frames. By pushing the second telescopic frame against the support frame, the angle formed between the two telescopic frames can be adjusted, thereby adjusting the support angle between the patient's calf and thigh. The telescopic function between the two telescopic frames allows for adaptive adjustments to different patients, thereby meeting the adaptability requirements of different patients. This allows the patient's lower limbs to be fixed in the standard treatment position. The adjustment process is relatively simple and easy to operate, providing patients with greater comfort and experience. This meets the requirements of visually guided positioning of each lower limb joint, embodying medical humanistic care.

[0006] As a further improvement to the above technical solution, the first fixing member is a double-ended latch that slides the slider. Multiple positioning holes are formed side by side on both sides of the support frame. Both ends of the latch are bent and inserted into the positioning holes on both sides of the support frame. By sliding the support frame and pulling both ends of the latch out of the positioning holes, the position of the second telescopic frame and the angle between the two telescopic frames can be adjusted. After determining the angular position of the two telescopic frames, the two ends of the latch are inserted into the closest positioning holes on both sides, thereby fixing the angular positions of the two telescopic frames. This is simple to operate, and the fixing method is stable and reliable.

[0007] As a further improvement to the above technical solution, the telescopic frame includes a first support and a second support that are slidably connected relative to each other. The first support is mounted with a rack, and the second support is rotatably mounted with a gear that meshes with the rack. The second support is also mounted with a limiting member for limiting the rotation of the gear. By rotating the gear, the rack drives the first support to slide relative to the second support, and the limiting member then limits the position of the gear, thereby limiting the extension and retraction of the first and second supports, thereby achieving the telescopic adjustment function of the telescopic frame, which is simple to operate and easy to adjust.

[0008] As a further improvement to the above technical solution, the limiting member includes a handle axially slidably mounted on the gear, wherein turning the handle drives the gear to rotate, the handle being mounted with a limiting block, and the second support having a limiting groove for the limiting block to engage with. When the limiting block engages with the limiting groove, the handle cannot be rotated. By pulling the handle so that it slides relative to the gear and drives the limiting block to engage with or extend from the limiting groove, the handle can be restricted or unlocked, thereby facilitating limiting the position of the gear or rotating the handle to drive the gear to rotate.

[0009] As a further improvement of the above technical solution, the telescopic frame and the foot support are respectively installed with Velcro fixing straps. The Velcro fixing straps can restrict the position of the lower limbs and feet on the telescopic frame or the foot support to restrain the lower limbs and feet.

[0010] As a further improvement of the above technical solution, the telescopic frame is installed with a cushion to improve the comfort of the patient.

[0011] As a further improvement to the above technical solution, a base frame is installed at the bottom of the support frame, one side of the support frame is rotatably connected to the base frame, the direction of the rotation axis of the support frame relative to the base frame is parallel to the direction in which the slider slides relative to the support frame, and a support rod is rotatably installed on the other side of the support frame. After the support frame is rotated relative to the base frame, the support rod is rotated until it contacts the top of the base frame, so that the support rod supports one side of the support frame, achieving swinging and fixing of the support frame relative to the base frame. When the support frame rotates relative to the base frame, the patient's lower limbs can be turned outward or inward, thereby improving the flexibility of the patient's lower limb position adjustment.

[0012] As a further improvement of the above technical solution, the base frame is provided with a groove for the support rod to fit in at a position corresponding to the rotation of the support rod. When the support rod is fitted into the groove, it can prevent the support rod from sliding relative to the base frame, thereby improving the support stability of the support rod and enhancing safety.

[0013] As a further improvement to the above technical solution, the base frame is provided with a receiving slot for the support frame to be inserted into, a cylindrical body is formed on both sides of the support frame, and a fan-shaped slot is provided on both sides of the receiving slot to match the cylindrical body. The support rods are rotatably mounted on both sides of the support frame. The cylindrical bodies on both sides of the support frame allow both sides of the support frame to rotate a certain angle within the fan-shaped slots on both sides of the base frame receiving slot, thereby achieving adjustment of the swing angle. That is, both sides of the support frame can achieve the function of lifting and supporting. When the two sides of the support frame are lifted by the support rods on the corresponding sides, the patient's lower limbs can be turned outward and inward, further improving flexibility.

[0014] As a further improvement to the above technical solution, both ends of the support frame are provided with axial holes coaxial with the cylindrical body, and both ends of the base frame are provided with rotating shafts that can be inserted into the axial holes. When one side of the support frame needs to be lifted, the rotating shaft on that side is pulled out, and the support frame on that side can be lifted, allowing the support frame to swing around the rotating shaft on the other side, thereby improving the stability and reliability of the support frame's swing relative to the base frame.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] Reference Figure 1-4The visual interventional therapy operation support for lower limb joints includes a support frame 100, two telescopic frames 200, a foot support 400, and a first fixing member. One end of the first telescopic frame 200 is rotatably mounted on one end of the support frame 100 via an axis, and the other end of the first telescopic frame 200 is rotatably connected to one end of the second telescopic frame 200 via an axis. The end of the second telescopic frame 200 away from the first telescopic frame 200 is rotatably mounted with a slider 150 via an axis. The slider 150 is in an inverted T-shape as a whole, and a T-slot for limiting the sliding of the slider 150 is provided at the top of the support frame 100. The first fixing member can limit the position of the slider 150 in the T-slot, thereby realizing the angular position limitation between the two telescopic frames 200.

[0026] Specifically, a support base 120 is mounted on both sides of the top of the slider 150. Each support base 120 defines a vertical slot 130. The first fixing member is a double-ended latch 140. The two ends of the double-ended latch 140 are respectively inserted into the vertical slots 130 of the two support bases 120 and can slide within the vertical slots 130. It should be noted that the middle cross-section of the double-ended latch 140 is square, which prevents the double-ended latch 140 from rotating within the vertical slots 130 and affecting the sliding stability of the double-ended latch 140 relative to the slider 150. A certain distance is provided between the two support bases 120 to facilitate grasping the middle of the double-ended latch 140 for operation. After the double-ended latch 140 is removed, the slider 150 can be moved by pushing the double-ended latch 140, thereby facilitating the adjustment of the telescopic frame 200 and improving adjustment efficiency.

[0027] The two ends of the double-ended latch 140 pass through the vertical slot 130 and then bend downward 90 degrees, giving the double-ended latch 140 an overall U-shaped structure. Multiple positioning holes 110 are arranged side by side on both sides of the support frame 100, parallel to the length of the T-slot 160. The diameter of the positioning holes 110 is slightly larger than the diameter of the two ends of the double-ended latch 140. When the double-ended latch 140 slides downward from its highest position, its two ends fit into the positioning holes 110 on either side, thereby limiting the sliding movement of the slider 150.

[0028] In other embodiments, the first fixing member may also be a threaded rod, which is threadedly connected to the slider 150 . The threaded rod is screwed through the slider 150 and pressed against the bottom of the T-slot 160 , thereby limiting the sliding of the slider 150 .

[0029] The telescopic frame 200 includes a first bracket 210 and a second bracket 220. A rack 230 is mounted on one side of the first bracket 210. The second bracket 220 has a receiving hole into which one end of the first bracket 210 can slide. The teeth of the rack 230 are arranged parallel to the direction in which the second bracket 220 slides relative to the first bracket 210. A gear 240 is rotatably mounted on the second bracket 220, meshing with the rack 230. The second bracket 220 is also equipped with a limiting member 300, which can limit the rotation of the gear 240. This allows the limiting member 300 to limit the rotation of the gear 240 when the angular position of the first bracket 210 and the second bracket 220 does not need to be adjusted. Therefore, by rotating the gear 240, the first bracket 210 and the second bracket 220 can slide relative to each other under the transmission action of the gear 240 and the rack 230, and then the gear 240 is restricted by the limiting member 300 to fix the relative positions of the first bracket 210 and the second bracket 220.

[0030] A transmission cylinder is coaxially provided on one side of the gear 240, and a square hole is provided in the transmission cylinder. The limiting member 300 includes a handle 310, and a square column is provided at one end of the handle 310 to be embedded in the square hole. The length of the square column is shorter than the depth of the square hole. A coil spring is provided on the bottom wall of the square hole, and one end of the coil spring is fixed to the bottom wall of the square hole, and the other end is fixed to the end of the square column. A limiting block 320 is integrally formed in the middle of the handle 310, wherein the cross section of the limiting block 320 is a pentagon. A limiting groove 330 is provided on one side of the second support 220, and the cross section of the limiting groove 330 is also a pentagon. The limiting groove 330 can be embedded in the limiting block 320.

[0031] Under the restriction of the coil spring, the restriction block 320 remains embedded in the restriction slot 330, preventing the gear 240 from rotating, thereby maintaining the current relative position of the first and second brackets 210, 220. It is also impossible to rotate the handle 310 to rotate the gear 240. When the relative position of the first and second brackets 210, 220 needs to be adjusted, the handle 310 is pulled to overcome the elastic force of the coil spring and disengage the restriction block 320 from the restriction slot 330, allowing the handle 310 to rotate, thereby driving the gear 240 to rotate together, achieving overall telescopic adjustment of the telescopic frame 200. After the adjustment is completed, the restriction block 320 can be released to embed it in the restriction slot 330, thereby restricting the handle 310 and preventing the telescopic frame 200 from being unstable. In addition, the coil spring can also limit the position of the handle 310, preventing the square column from disengaging from the square hole, and maintaining the transmission relationship between the handle 310 and the gear 240.

[0032] In other embodiments, the limiting member can also be a screw spirally installed on the second support 220. The screw is rotated through the second support 220 and pressed against one side of the gear 240 to achieve the purpose of limiting the rotation of the gear 240. After loosening the screw, the length of the telescopic frame 200 can be adjusted by rotating the gear 240.

[0033] The foot support 400 is an L-shaped plate. The foot support 400 is detachably mounted on the first support 210 of the second telescopic frame 200 at one end away from the second support 220 by means of bolts. The second support 220 of the two telescopic frames 200 is respectively mounted with a Velcro fixing belt 500, and the foot support 400 is also mounted with a Velcro fixing belt 500. The Velcro fixing belt 500 includes a fixing rope and Velcro. The Velcro can form a closed loop with the fixing rope to fix the lower limbs or feet, thereby preventing the patient's lower limbs or feet from moving around and affecting the body position. In other embodiments, the foot support 400 can be rotatably mounted on the second telescopic frame 200 by means of a damping shaft structure, thereby facilitating adjustment of the support angle between the foot and the calf.

[0034] A soft cushion 600 is fixed to the side of the two telescopic frames 200 away from the support frame 100. An elastic band 610 is connected between the first support platform 210 and the second support platform 220 of one telescopic frame 200, allowing the telescopic frames 200 to extend and retract. An elastic band 610 is also connected between the two telescopic frames 200 to prevent the two telescopic frames 200 from easily pinching the patient's lower limbs during swinging. The soft cushion 600 can be an air cushion, sponge cushion, or silicone cushion.

[0035] Optionally, a base frame 700 is installed at the bottom of the support frame 100. The bottom area of ​​the base frame 700 is larger than the top area, so that the base frame 700 has a trapezoidal structure as a whole, thereby improving the stability of the base frame 700. A receiving groove 730 is formed at the top of the base frame 700. The two side walls of the receiving groove 730 are formed with a quarter-circular arc fan-shaped groove 750. Cylinders 740 are provided on both sides of the support frame 100. The diameter of the cylinder 740 is exactly the same as the thickness of the support frame, and the radius of the cylinder 740 is the same as the radius of the fan-shaped groove 750. Therefore, the support frame 100 can be precisely embedded in the receiving groove 730. At this time, the axes of the cylinder 740 and the fan-shaped groove 750 are parallel to the sliding direction of the slider 150. When one side of the support frame 100 is lifted, the surface of the cylindrical body 740 on the other side of the support frame 100 slides in the fan-shaped groove 750, allowing the support frame 100 to form a relatively stable swinging motion around the central axis of the cylindrical body 740 on the other side, thereby improving the swing stability of the support frame 100. Support rods 710 are rotatably mounted on both sides of the bottom of the support frame 100. When the support frame 100 is not lifted relative to the base frame 700, the support rods 710 are arranged flush with the bottom of the support frame 100. When one side of the support frame 100 is lifted, the support rod 710 on that side can rotate due to gravity or manual swinging. When the support rod 710 contacts the top of the base frame 700, the support rod 710 can prop up the support frame 100 and keep the support frame 100 in a swinging posture. Indented notches 170 are provided on both sides of the support frame 100 to facilitate gripping and lifting the support frame 100. A groove 720 for the support rod 710 to be embedded in is provided at the bottom of the accommodating groove 730 . The groove 720 can prevent the support rod 710 from slipping, thereby improving the stability of the swing angle of the support frame 100 .

[0036] To further enhance the stability of the support frame 100's swing relative to the base frame 700, rotating shafts 770 are provided on both sides of the base frame 700. The axis of each rotating shaft 770 coincides with the axis of the corresponding cylindrical body 740. Axial holes 760 are provided on both sides of the support frame 100. The center lines of the shaft holes 760 coincide with the axis of the corresponding cylindrical body 740. The rotating shafts 770 pass through the base frame 700 and are embedded in the corresponding shaft holes 760, thereby restraining the support frame 100 within the base frame 700.

[0037] When the support frame 100 needs to be swung relative to the base frame 700, the two rotating shafts 770 on one side are pulled out of the shaft hole 760, and the support frame 100 can be lifted on that side. When the support frame 100 is lifted, it swings around the rotating shaft 770 on the other side, thereby realizing the swing of the support frame 100, and the patient's lower limbs can be subjected to both outward and inward rotation actions.

[0038] In other embodiments, the support frame 100 may be provided with a fixed shaft structure on only one side for rotational connection with the base frame 700, while no shaft structure is provided on the other side to facilitate lifting the support frame 100. Only one support rod 710 is provided and is located at the bottom side of the lifted support frame 100. This allows the patient's lower limbs to be either everted or buckled.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
