Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning bracket technology, specifically an orthopedic positioning bracket. Background Technology
[0002] A positioning stent is a medical device, usually made of metal or polymer materials, that is an auxiliary device with a specific shape and structure. It is used to precisely position, fix, and support bones, joints, or implants during orthopedic surgery or treatment. Its design purpose is to ensure the accuracy of surgical procedures, improve treatment outcomes, and reduce damage to surrounding tissues.
[0003] The existing utility model with authorization announcement number CN214388113U discloses an orthopedic Kirschner wire positioner. By setting up a bracket, a lead screw, a rotating handle, and a clamping plate, it can support and fix the patient's leg, avoiding the inconvenience of Kirschner wire positioning caused by the difficulty of fixing and supporting the patient's leg. It meets the needs of orthopedic Kirschner wire positioners. By setting up a sleeve, a fixing frame, a rotating rod, and a positioning tube, it can rotate and position the Kirschner wire, avoiding the low surgical efficiency caused by the small positioning range of the Kirschner wire, and improving the efficiency of orthopedic Kirschner wire positioners.
[0004] While the above-mentioned technical solution can locate the patient's legs and improve the positioning range and efficiency, it requires the use of screws and levers, lacking a quick positioning structure that can rapidly fix the patient's limbs. This results in a relatively slow positioning of the patient's limbs, which affects the progress of treatment.
[0005] Therefore, those skilled in the art have provided an orthopedic positioning bracket to address the problems mentioned in the background section. Utility Model Content
[0006] The purpose of this invention is to provide an orthopedic positioning bracket to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The quick positioning mechanism includes a first electric telescopic rod, the telescopic end of which is fixedly connected to an arc-shaped support plate. Two positioning pins are provided inside the base frame. A button controller is fixedly connected to the front of the base frame. Two second electric telescopic rods are fixedly connected to the inner wall of the arc-shaped frame. Two support plates are provided inside the arc-shaped frame. A pressure sensor is fixedly connected to the bottom surface of each support plate. An arc-shaped clamping plate is provided below each support plate. Four guide rods are fixedly connected to the upper surface of each arc-shaped clamping plate.
[0010] As a further embodiment of this utility model: the outer surface of the arc-shaped frame is in contact with the inner wall of the base frame; the outer surface of the first electric telescopic rod is fixedly connected to the inner bottom wall of the base frame; the outer surface of each positioning pin is in contact with the inner wall of the base frame and the inner wall of the arc-shaped frame respectively; the upper surface of each support plate is fixedly connected to the telescopic end of the second electric telescopic rod; the upper surface of each arc-shaped clamp is in contact with the bottom surface of the pressure sensor; the outer surface of each guide rod is slidably connected to the inside of the support plate; the first electric telescopic rod, the two second electric telescopic rods, and the two pressure sensors are all electrically connected to the button controller via wires; mounting plates are fixedly connected to the front and back of the base frame; and the upper surface of each mounting plate has several identical mounting holes.
[0011] As a further improvement of this utility model: each of the positioning pins is fixedly connected to an anti-slip sleeve on its outer surface, and each of the anti-slip sleeves is fixedly connected to a plurality of identical anti-slip protrusions on its outer surface.
[0012] As a further embodiment of this utility model: the inner wall of the arc-shaped frame is fixedly connected to two sliding rods, the outer surfaces of the two sliding rods are slidably connected to a sliding plate, and the inner wall of the sliding plate is fixedly connected to a positioning tube.
[0013] As a further improvement of this utility model: the inner wall of the slide plate is threaded with two hand-tightening screws, and the ends of the two hand-tightening screws that are close to each other are in contact with the outer surfaces of the two slide rods respectively.
[0014] As a further improvement of this utility model: the inner wall of the arc-shaped support plate is fixedly connected with a first anti-slip pad, and the inner wall of each arc-shaped clamp is fixedly connected with a second anti-slip pad.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention utilizes a base frame, an arc-shaped frame, a first electric telescopic rod, an arc-shaped support plate, a button controller, positioning pins, a second electric telescopic rod, a support plate, an arc-shaped clamp, a guide rod, and pressure sensors in a coordinated manner. The patient's limbs can be placed on the arc-shaped support plate. After the arc-shaped frame is flipped downwards, it is fixed relative to the base frame by the insertion of two positioning pins. Operating the button controller extends the first electric telescopic rod until the arc-shaped support plate lifts the patient's limbs into a suitable position near the two arc-shaped clamps. Then, operating the button controller extends the two second electric telescopic rods, and the two arc-shaped clamps, in conjunction with the arc-shaped support plate, clamp the patient's limbs until the opposing forces exerted on the two pressure sensors by the arc-shaped clamps reach the preset appropriate force by the button controller. This allows for rapid fixation of the patient's limbs simply by inserting and removing the positioning pins and operating the button controller, improving the efficiency of limb fixation and avoiding the problem of slow limb fixation and delayed treatment progress caused by the lack of a quick fixation structure.

[0022] Please see Figure 1-4An orthopedic positioning bracket includes a base frame 1, with an arc-shaped frame 2 hinged to the back of the base frame 1. A quick positioning mechanism 3 is installed inside the base frame 1, comprising a first electric telescopic rod 301. An arc-shaped support plate 302 is fixedly connected to the telescopic end of the first electric telescopic rod 301. The outer surface of the arc-shaped frame 2 contacts the inner wall of the base frame 1, and the outer surface of the first electric telescopic rod 301 is fixedly connected to the inner bottom wall of the base frame 1. Mounting plates 4 are fixedly connected to both the front and back of the base frame 1. Each mounting plate 4 has several identical mounting holes 5 on its upper surface. By using the mounting holes 5, the mounting plates 4 can be fixed to a support surface suitable for limb surgery, such as an operating table, using external bolts or other positioning structures, thus facilitating the fixed installation of the entire positioning bracket.
[0023] The base frame 1 has two positioning pins 304 inside. The outer surface of each positioning pin 304 contacts the inner wall of the base frame 1 and the inner wall of the arc frame 2, respectively. A button controller 303 is fixedly connected to the front of the base frame 1. The button controller 303 has a built-in speaker, so that it can emit a completion prompt sound after the bracket has finished clamping the patient's limbs. Each positioning pin 304 has an anti-slip sleeve 12 fixedly connected to its outer surface. Each anti-slip sleeve 12 has several identical anti-slip protrusions 13 fixedly connected to its outer surface. By setting the anti-slip protrusions 13, the anti-slip property of the outer surface of the anti-slip sleeve 12 can be increased. By setting the anti-slip sleeve 12 and the anti-slip protrusions 13, the anti-slip effect of the outer surface of the positioning pin 304 can be increased, thereby facilitating the insertion and removal of the positioning pin 304.
[0024] Two second electric telescopic rods 305 are fixedly connected to the inner wall of the arc-shaped frame 2. Two support plates 306 are provided inside the arc-shaped frame 2. The upper surface of each support plate 306 is fixedly connected to the telescopic end of the second electric telescopic rod 305. Two slide rods 8 are fixedly connected to the inner wall of the arc-shaped frame 2. A slide plate 9 is slidably connected to the outer surface of the two slide rods 8. A positioning tube 10 is fixedly connected to the inner wall of the slide plate 9. By setting the slide plate 9, it can slide left and right along the outer surface of the two slide rods 8, thereby facilitating the adjustment of the position of the positioning tube 10. By setting the positioning tube 10, it can provide guidance for Kirschner wires or other needle-like structures.
[0025] Each support plate 306 has a pressure sensor 309 fixedly connected to its bottom surface. Each support plate 306 has an arc-shaped clamp 307 below it. The upper surface of each arc-shaped clamp 307 is in contact with the bottom surface of the pressure sensor 309. The first electric telescopic rod 301, the two second electric telescopic rods 305, and the two pressure sensors 309 are all electrically connected to the button controller 303 through wires. The inner wall of the slide plate 9 is threaded with two hand-tightening screws 11. The ends of the two hand-tightening screws 11 that are close to each other are in contact with the outer surfaces of the two slide rods 8. By setting the hand-tightening screws 11, it is convenient to tighten the outer surface of the slide rod 8 after hand-tightening, thereby conveniently fixing the position of the positioning tube 10 relative to the slide rod 8.
[0026] Each arc-shaped clamp 307 has four guide rods 308 fixedly connected to its upper surface. The outer surface of each guide rod 308 is slidably connected to the inside of the support plate 306. The inner wall of the arc-shaped support plate 302 is fixedly connected to a first anti-slip pad 6, and the inner wall of each arc-shaped clamp 307 is fixedly connected to a second anti-slip pad 7. By setting the first anti-slip pad 6, the anti-slip properties of the inner wall of the arc-shaped support plate 302 can be increased. By setting the second anti-slip pad 7, the anti-slip properties of the inner wall of the arc-shaped clamp 307 can be increased, thereby jointly increasing the stability when clamping and positioning the patient's limbs.
[0027] The working principle of this utility model is as follows: In use, the two positioning pins 304 are pulled out of the base frame 1. Then, the arc-shaped frame 2 is flipped upwards, and the patient's limbs are placed on the arc-shaped support plate 302 in a suitable posture. Afterwards, the arc-shaped frame 2 is flipped downwards and fixed relative to the base frame 1 by the insertion of the two positioning pins 304. Then, the button controller 303 is operated to extend the first electric telescopic rod 301 until the arc-shaped support plate 302 lifts the patient's limbs in a suitable posture to a position close to the two arc-shaped clamps 307. Then, the button controller 303 is operated to extend the two second electric telescopic rods 305 respectively. Then, the two arc-shaped clamps 307 cooperate with the arc-shaped support plate 307 to extend the two second electric telescopic rods 305 respectively. The shaped support plate 302 clamps the patient's limb until the opposing forces exerted on the two pressure sensors 309 by the arc-shaped clamp 307 reach the appropriate preset force by the button controller 303. At this point, the built-in speaker of the button controller 303 emits a positioning completion prompt tone, so that the fixation of the patient's limbs can be quickly completed by simply inserting and removing the positioning pins 304 and operating the button controller 303, which improves the efficiency of limb positioning. The design of the entire orthopedic positioning bracket effectively solves the problem that the lack of a quick positioning structure that can quickly fix the patient's limbs leads to slow limb positioning and affects the treatment progress.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
