It should be understood that the present utility model uses terms such as "first" and "second" to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.
[0025] Please refer to Figures 1 to 3, a preferred embodiment of the present utility model provides a body position fixing device, which includes a base 1, a support plate 2 and an angle adjustment mechanism 3; connecting rods 4 are respectively arranged on the left and right sides of the support plate 2, the upper ends of the connecting rods 4 are fixedly connected to the support plate 2 and are perpendicularly arranged to the support plate 2, and the lower ends of the connecting rods 4 are rotatably connected to the base 1 in the front and rear directions; a connecting shaft 5 is fixedly connected between the connecting rods 4 on the left and right sides, and the angle adjustment mechanism 3 is connected to the connecting shaft 5 and can adjust the included angle formed between the connecting rod 4 and the base 1; a soft pad 6 is covered on the support plate 2. Wherein, the included angle is preferably 90°-180°.
[0026] For the body position fixing device according to the present utility model, during use, first determine the lesion position and the body position that the patient needs to fix through preoperative ultrasound, and then place the body position fixing device on the operating table and place it on the back of the affected side where the patient's lesion is located to play a supporting role. When the patient needs to maintain a large lateral lying angle, the angle adjustment mechanism 3 can drive the connecting shaft 5 to rotate, and the connecting shaft 5 can drive the connecting rod 4 and the support plate 2 to rotate, so that the support plate 2 supports on the patient's back. Since the soft pad 6 is covered on the support plate 2, the comfort of the patient can be improved. It can be seen that the present utility model can adjust the inclination of the lateral lying body position of the patient through the angle adjustment mechanism 3, which is convenient for the selection of the puncture path under ultrasound guidance; after the operation is completed, the angle adjustment mechanism 3 can drive the connecting shaft 5 to rotate in the reverse direction, and the connecting shaft 5 can drive the connecting rod 4 and the support plate 2 to rotate in the reverse direction until the support plate 2 is reset, with a simple structure and convenient use.
[0027] Exemplarily, the angle adjustment mechanism 3 includes a driving motor 31, a worm and worm gear pair 32, and a bearing block 33. The driving motor 31 is fixedly installed on the base 1. The power output end of the driving motor 31 is connected to one end of the worm 321 of the worm and worm gear pair 32. The other end of the worm 321 of the worm and worm gear pair 32 is rotatably connected to the bearing block 33. The worm gear 322 of the worm and worm gear pair 32 is fixedly connected to the connecting shaft 5. When the patient needs to maintain a relatively large lateral lying angle, the driving motor 31 rotates forward. At the same time, the worm and worm gear pair 32 can drive the connecting shaft 5 to rotate, and the connecting shaft 5 can drive the connecting rod 4 and the support plate 2 to rotate. After the operation is completed, the driving motor 31 rotates in reverse. At the same time, the worm and worm gear pair 32 can drive the connecting shaft 5 to rotate in the opposite direction, and the connecting shaft 5 can drive the connecting rod 4 and the support plate 2 to rotate in the opposite direction until the support plate 2 returns to its original position. Moreover, the setting of the bearing block 33 can improve the stability of the angle adjustment mechanism 3 during operation. Further, the angle adjustment mechanism 3 further includes an installation box 34. The installation box 34 is fixedly installed on the base 1. The driving motor 31, the worm and worm gear pair 32, and the bearing block 33 are all arranged inside the installation box 34, which can protect the driving motor 31, the worm and worm gear pair 32, and the bearing block 33.
[0028] Exemplarily, as Figure 2 shown, the connecting rod 4 is a telescopic structure. Specifically, the connecting rod 4 includes an outer tube 41 and an inner tube 42. The upper end of the outer tube 41 is fixedly connected to the support plate 2. The lower end of the inner tube 42 is rotatably connected to the base 1. The inner tube 42 is slidably sleeved in the outer tube 41. The outer tube 41 and the inner tube 42 are locked by a locking assembly 43. Such a design can facilitate the operator to adjust the height of the support plate 2 relative to the base 1, so as to be applicable to the support of patients with different body types, and has strong versatility. Further, in this embodiment, the locking assembly 43 includes a pin 431, a first pin hole 432, and a plurality of second pin holes 433. The first pin hole 432 is provided on the outer tube 41. A plurality of the second pin holes 433 are all provided on the inner tube 42 and are arranged at equal intervals along the height direction of the inner tube 42. The pin 431 sequentially passes through the first pin hole 432 and the second pin holes 433. The pin 431 is connected to the outer tube 41 through a rope body 434. Thus, multi-stage adjustment of the height of the connecting rod 4 can be achieved, and the operation is simple and convenient. Secondly, the connection between the outer tube 41 and the inner tube 42 is reliable, which can improve the structural stability of the device. In addition, since the pin 431 is connected to the outer tube 41 through the rope body 434, the pin 431 is not easily lost, and the practicability is strong.
[0029] Exemplarily, the body position fixing device of the present utility model further includes a triangular limiting plate 7, and one right-angled side of the triangular limiting plate 7 is fixedly connected to the lower end of the connecting rod 4; when the included angle formed between the connecting rod 4 and the base 1 is 90°, the other right-angled side of the triangular limiting plate 7 can abut against the base 1. Thus, by providing the triangular limiting plate 7, the connecting rod 4 and the support plate 2 can be limited, making the device more stable when supporting the patient's back.
[0030] Exemplarily, the body position fixing device of the present utility model further includes a bedside fixing assembly. The bedside fixing assembly 8 includes a fixing frame 81 and a pressing bolt 83. The fixing frame 81 is provided with a clamping opening 82 matching the bed board, and the fixing frame 81 and the bed board can be pressed tightly through the pressing bolt 83. During use, the device can be fixed on the side of the operating bed close to the patient's back, thus saving space. Moreover, this fixing method is convenient for installation and disassembly, and can adapt to different types of operating beds, with strong versatility.
[0031] Exemplarily, when the device supports the patient's back, to further improve the comfort of the patient, an arc portion 9 is provided between the support plate 2 and the connecting rod 4, and the soft pad 6 wraps the arc portion 9.
[0032] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0033] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
