Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spinal traction, and specifically relates to a traction mechanism for orthopedic spinal surgery. Background Technique
[0002] Spinal traction, also known as spinal traction, has various methods. According to the patient's position during treatment, it can be divided into lying traction, sitting traction, oblique traction or upright traction. According to the source of the traction force, it can be further divided into self-weight traction of the patient, manual traction, mechanical traction, and electric traction. According to the duration of the traction, it can be divided into continuous traction and intermittent traction.
[0003] The existing traction mechanism for orthopedic spinal surgery is provided with an arc-shaped seat body. By allowing the patient to lie flat on the arc-shaped seat body and lean back by themselves, the spinal traction of the patient is carried out. This method can only perform flat traction and cannot perform prone traction. If a groove is opened for prone traction, the patient's toes will touch the traction mechanism, causing the toes to bend and the feet to be unable to stretch normally. Therefore, a traction mechanism for orthopedic spinal surgery is proposed. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a traction mechanism for orthopedic spinal surgery, which has the advantages of being convenient for spinal traction and avoiding interference with the feet during traction.
[0005] To achieve the purpose of being convenient for spinal traction and avoiding interference with the feet during traction, the utility model provides the following technical solution: a traction mechanism for orthopedic spinal surgery, including a chassis, a support rod is fixedly installed on the top of the chassis, a lying board is fixedly installed on the top of the support rod, and a synchronous adjustment component for being convenient for spinal traction and avoiding interference with the feet during traction is arranged on the chassis and the lying board;
[0006] The synchronous adjustment component includes a backrest board, a tail board, a driving rod, a connecting rod and an electric push rod. The backrest board is rotatably connected to one side wall of the lying board, the tail board is rotatably connected to the other side wall of the lying board, the driving rod is fixedly installed at the bottoms of the backrest board and the tail board, the connecting rod is hinged between the opposite sides of the two driving rods, and the electric push rod is hinged between the opposite sides of the chassis and the backrest board.
[0007] Further, the shape of the chassis is a Chinese character "Ri", and connecting seats for hinging the electric push rod are fixedly connected to the top of the chassis and the bottom of the backrest board.
[0008] Further, mounting holes are opened on the chassis, and soft cushion pads are arranged on the lying board, the backrest board and the tail board.
[0009] Further, connecting blocks are fixedly installed on the front and rear walls of the lying board and the backrest board. Connecting bands are connected to both sides of the connecting blocks, and magic tapes are sewn on the outer surfaces of the front and rear connecting bands.
[0010] Further, the connecting band is made of nylon, and the magic tapes can be adhered to each other.
[0011] Compared with the prior art, the utility model provides a traction mechanism for orthopedic spine surgery, which has the following beneficial effects:
[0012] In the traction mechanism for orthopedic spine surgery, by setting a synchronous adjustment component, after the synchronous adjustment component is used, under the telescopic action of the electric push rod, the backrest board is driven to rotate upward or downward. Under the connection of the connecting rod to the driving rods on the backrest board and the tail board, when the backrest board rotates downward, the tail board rotates upward to a horizontal state, allowing the patient to lie flat for spinal traction. When the backrest board rotates upward, the tail board rotates downward to an inclined state, allowing the patient to lie prone for spinal traction. The tail board will not interfere with the toes of the feet, which is beneficial to the extension of the patient's toes. Two methods of lying flat and lying prone are adopted, so as to facilitate spinal traction and avoid interfering with the feet during traction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.
[0017] Please refer to Figure 1-2 , a traction mechanism for orthopedic spine surgery, including a chassis 1. The shape of the chassis 1 is a Chinese character 'Ri' shape. Mounting holes 5 are provided on the chassis 1, and screws are used to pass through the chassis 1 for fixing or disassembling work. A support rod 2 is fixedly installed on the top of the chassis 1, and a lying board 3 is fixedly installed on the top of the support rod 2. People can lie or lie prone on the lying board 3 for spinal traction work.
[0018] Please see Figure 1-2 The base frame 1 and the reclining board 3 are equipped with a synchronous adjustment component 4 to facilitate spinal traction and avoid obstructing the feet during traction. The synchronous adjustment component 4 includes a backrest 41, a tail plate 42, a drive rod 43, a connecting rod 44, and an electric push rod 45. The backrest 41 is rotatably connected to one side wall of the reclining board 3 and can rotate up and down around the reclining board 3. The tail plate 42 is rotatably connected to the other side wall of the reclining board 3 and can rotate up and down around the reclining board 3. Soft pads 6 are provided on the reclining board 3, the backrest 41, and the tail plate 42 to ensure the comfort of the patient when performing spinal traction.
[0019] Furthermore, the drive rod 43 is fixedly installed at the bottom of the backrest 41 and the tail plate 42, and can move together with the backrest 41 or the tail plate 42. The connecting rod 44 is hinged between the two drive rods 43 on opposite sides. With the connection of the connecting rod 44, the backrest 41 and the tail plate 42 can rotate together. The electric push rod 45 is hinged between the base frame 1 and the backrest 41 on opposite sides. When the electric push rod 45 retracts, it can pull the backrest 41 to rotate downwards. With the connection of the connecting rod 44, the tail plate 42 rotates upwards to a horizontal state, which is suitable for patients to lie flat for spinal traction. When the electric push rod 45 extends, it can push the backrest 41 to rotate upwards. With the connection of the connecting rod 44, the tail plate 42 rotates downwards to an inclined state, which is suitable for patients to crawl for spinal traction. The top of the base frame 1 and the bottom of the backrest 41 are both fixedly connected with connecting seats that are hinged to the electric push rod 45.
[0020] Please see Figure 1-2 Connecting blocks 7 are fixedly installed on the front and back walls of the reclining board 3 and the backrest board 41. Connecting straps 8 are connected to the connecting blocks 7 on both sides. The connecting straps 8 are made of nylon, which makes them wear-resistant and elastic, and convenient for binding the upper and lower body. The outer surfaces of the connecting straps 8 on both sides are sewn with Velcro, which can connect the two ends of the connecting straps 8. The Velcro can be glued to each other, so that the upper surface of one end can be glued to the lower surface of the other end, or the lower surface of one end can be glued to the upper surface of the other end, thus realizing the connection of the two ends of the connecting straps 8.
[0021] In this embodiment, when the patient is lying down for spinal traction, the connecting strap 8 is used to bind the patient's upper and lower body. Adjusting the retraction of the electric push rod 45 causes the backrest 41 to rotate downwards. With the connection of the connecting rod 44, the tail plate 42 gradually rotates upwards. The backrest 41 provides downward traction to the patient's lower back, while the tail plate 42 rotates upwards to a horizontal position to support the feet. When the patient is lying prone for spinal traction, the connecting strap 8 is used to bind the patient's upper and lower body. Adjusting the extension of the electric push rod 45 causes the backrest 41 to rotate upwards. With the connection of the connecting rod 44, the tail plate 42 gradually rotates downwards. The backrest 41 provides upward traction to the patient's lower back, while the tail plate 42 rotates downwards to an inclined position to avoid obstructing the feet and toes, preventing the toes from contacting the soft pad 6, thus facilitating the patient's comfort.
[0022] The beneficial effects of the above embodiments are as follows:
[0023] This orthopedic spinal traction mechanism, through the setting of a synchronous adjustment component 4, drives the backrest 41 to rotate upward or downward under the extension and retraction of the electric push rod 45. With the connection of the connecting rod 44 to the drive rod 43 on the backrest 41 and the tail plate 42, when the backrest 41 rotates downward, the tail plate 42 rotates upward to a horizontal state, allowing the patient to lie flat for spinal traction. When the backrest 41 rotates upward, the tail plate 42 rotates downward to an inclined state, allowing the patient to lie prone for spinal traction. The tail plate 42 does not obstruct the feet and toes, which is conducive to the extension of the patient's feet and toes. It adopts both lying flat and lying prone methods, which facilitates spinal traction and avoids obstruction to the feet during traction.
[0024] The electric actuator 45 mentioned in the text is electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in the text.
