Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical positioning fixation, and in particular to a surgical positioning fixation system. Background Technology
[0002] During surgery, especially surgical procedures, the patient's position may change depending on the surgical site, such as lying flat, prone, or on their side. During surgical anesthesia, without external assistance, it is difficult for the patient to maintain a fixed lateral position for an extended period of time, making the surgical procedure difficult.
[0003] Currently, there are no ready-made products to meet the above requirements. Patients are maintained in their position through temporary measures such as hand support and padding. However, these measures are not stable enough and are difficult to meet the requirements for some special postures, which affects the quality and progress of the operation. The position fixation devices in most hospitals are rudimentary and not securely connected to the operating table, resulting in poor position fixation and obvious drawbacks during the operation.

The fixator, the positioning shaft, and the foot pedal are all inserted into the positioning plate. The fixator is inserted into the edge of the positioning plate to fix the position of the positioning plate on the operating table. The positioning shaft and the foot pedal are both inserted into the positioning plate to fix the patient's position.
[0006] Preferably, the positioning plate includes a long plate and a short plate, both the long plate and the short plate are provided with a plurality of round holes, the long plate and the short plate are arranged perpendicularly, and the inner side of the short plate is connected to one end of the long plate by a mortise and tenon structure.

The first pressure plate is inserted into the long plate to fix the position of the long plate on the operating table, and the second pressure plate is inserted into the short plate to fix the position of the short plate on the operating table.
[0009] Preferably, the positioning shaft includes a long shaft, a middle shaft, and a short shaft. Each of the long shaft, the middle shaft, and the short shaft includes a rigid shaft core for support and a soft bushing for preventing pressure sores. One end of the shaft core of the middle shaft and the short shaft extends out of the bushing for insertion into the round hole of the long plate. Both ends of the shaft core of the long shaft extend out of the bushing. One end of the shaft core of the long shaft is inserted into the round hole of the long plate, and the other end of the shaft core of the long shaft is used for binding with straps or ropes.

[0018] Example
[0019] like Figure 1 As shown, a surgical positioning system includes a positioning plate 1, a fixator 2, a positioning shaft 4, and a foot pedal 3. The fixator 2, positioning shaft 4, and foot pedal 3 are all inserted into the positioning plate 1. The fixator 2 is inserted into the edge of the positioning plate 1 to fix the position of the positioning plate 1 on the operating table. The positioning shaft 4 and foot pedal 3 are both inserted into the positioning plate 1 to fix the patient's position. The position of the positioning shaft 4 inserted into the positioning plate 1 varies depending on the patient's position, so that the positioning shaft 4 can provide support at multiple points on the patient. The positioning plate 1 includes a long plate 101 and a short plate 102. Both the long plate 101 and the short plate 102 are provided with several round holes. The long plate 101 and the short plate 102 are arranged perpendicularly. The inner side of the short plate 102 is connected to one end of the long plate 101 by a tenon and mortise structure. The fixator 2 includes a rod 201 and a pressure plate 202. The rod 201 is arranged perpendicularly to the pressure plate 202 and is connected by bolts. The pressure plate 202 is provided with a strip groove for adjusting the position of the rod 201.
[0020] The pressure plate 202 includes a first pressure plate 2021 and a second pressure plate 2022. The first pressure plate 2021 is inserted into the long plate 101 to fix the position of the long plate 101 on the operating table. The second pressure plate 2022 is inserted into the short plate 102 to fix the position of the short plate 102 on the operating table. The positioning shaft 4 adopts an ergonomic structural design that is thinner in the middle and thicker at both ends, making the positioning shaft 4 more suitable for human use. The positioning shaft 4 includes a long shaft 403, a middle shaft 402, and a short shaft 401. The long shaft 403, the middle shaft 402, and the short shaft 401 all include a rigid shaft core that provides support and a protective structure. The soft bushings for pressure ulcer protection have bushings extending from one end of the central shaft 402 and the short shaft 401 for insertion into the round hole of the long plate 101. Bushings extend from both ends of the long shaft 403. One end of the long shaft 403 is inserted into the round hole of the long plate 101, and the other end of the long shaft 403 is used for binding with straps or ropes. The foot pedal 3 includes a high foot pedal 301 and a low foot pedal 302. Both the high foot pedal 301 and the low foot pedal 302 include a rigid frame for support and soft silicone for pressure ulcer prevention. The bottom of the rigid frame is provided with a post, which is inserted into the round hole on the positioning plate 1.
[0021] Working principle: When in use, if the patient needs to maintain a lateral decubitus position, two parallel long boards 101 are placed horizontally on the operating table, separated in the middle, exposing the foam padding of the operating table. The patient lies on the separated area of the two long boards 101, i.e., the area where the foam padding is exposed, which can reduce the risk of pressure sores. Then, a positioning shaft 4 is inserted into the positioning plate 1 corresponding to the pubic bone and sacrum of the patient, and a positioning shaft 4 is inserted into the positioning plate 1 corresponding to the chest and back of the patient, so that the patient's torso can be stably fixed. If it is necessary to use straps to bind the patient, the long shaft 403 can be inserted into the corresponding position of the positioning plate 1, and the two ends of the strap can be tied to the upper end of the long shaft 403 for fixation. If it is necessary to maintain a supine position with knees bent, the foot pedal 3 can be inserted into the positioning plate 1 to provide support points for the feet and legs.
[0022] Therefore, the surgical positioning fixation system of the present invention, which adopts the above structure, realizes the rapid fixation of the patient's position and can adapt to various patient positions, especially suitable for patients in lateral and supine positions with knees bent. The operation before and after the operation is particularly simple and quick, which facilitates the operation and saves manpower.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
