[0002] Surgery is abbreviated as operation, commonly known as opening the door, which refers to the process of entering the human body or other biological tissues through surgical equipment or surgical instruments under the operation of surgeons or other professionals to eliminate lesions, change structures or implant foreign objects by external means.

[0003] After searching, the publication number CN215350351U discloses a human body positioning device for thoracic surgery, which can easily drive two sets of positioning splints to be close by setting a rotating shaft, a gear ring, a gear plate, a threaded slider, a screw, a handwheel, a gear ring and other mechanisms, so as to facilitate the restriction of the patient's body position on both sides and achieve the function of body position fixation. However, the device still has some defects in actual use. For example, the use range of the device is relatively fixed, and it can only limit a certain part of the patient. The flexibility of use is poor and cannot meet different usage requirements. At the same time, the device can only limit the patient's sides. When the patient is in a state of local anesthesia, it is easy to move upward due to the pain stimulation of the operation, which will affect the progress of the operation.

[0027] See also Figure 1-4 ,The utility model provides a technical solution:

[0028] A body position fixing device comprises an operating table 1, a fixing block 4 is fixedly arranged on the lower side of the operating table 1, mounting grooves 5 are provided on both sides of the fixing block 4, threaded rods 6 are rotatably arranged on the inner sides of two sets of mounting grooves 5, threaded blocks 7 are threadedly sleeved on the outer sides of the threaded rods 6, a connecting plate 9 is movably arranged on the outer sides of the threaded blocks 7, a connecting rod 10 is fixedly arranged on the outer sides of the connecting plate 9, a limited position frame 11 is fixedly arranged on the outer end of the connecting rod 10, an L-shaped block 12 is movably inserted and inserted into the inner side of the limiting frame 11, a threaded rod 16 is fixedly arranged on the outer sides of the L-shaped block 12, and a threaded rod 16 is fixedly arranged on the outer sides of the threaded blocks 7. The second rod 16 movably passes through the limit frame 11 and extends to the outside, and the outer side of the threaded rod 16 is located on the outer side of the limit frame 11 and a butterfly nut 17 is threadedly sleeved thereon. The outer side of the limit frame 11 is penetrated by a slide groove 18 for docking with the second threaded rod 16. The threaded rod 16 movably passes through the mounting groove 5 and extends to the outside, and the outer end of the threaded rod 16 is located on the outer side of the mounting groove 5 and a turntable 14 is fixedly provided thereon. The position of the limit frame 11 and the L-shaped block 12 is convenient to adjust, so as to facilitate the limit fixation according to different positions of the patient to meet different usage requirements.

[0029] Specifically, a soft cushion 2 and a head cushion 3 are respectively provided on the upper side of the operating table 1. The soft cushion 2 and the head cushion 3 can improve the patient's supine comfort, thereby facilitating surgery.

[0030] Furthermore, an electric push rod 8 is provided on the outside of the threaded block 7, one end of the electric push rod 8 is connected to the threaded block 7, and the other end of the electric push rod 8 is connected to the connecting plate 9. Turning on the electric push rod 8 through an external power supply can conveniently drive the limit frame 11 to fit on both sides of the patient, thereby improving the fixation effect on the patient and being suitable for patients of different body shapes.

[0031] It is worth mentioning that two sets of limiting grooves 13 for docking the threaded block 7 are opened on the inner side of the installation groove 5. The threaded block 7 slides in the limiting grooves 13. The limiting grooves 13 can limit the threaded block 7, so that when the threaded rod 6 rotates, it can drive the threaded block 7 to move parallel to the threaded rod 6, thereby improving the movement stability of the threaded block 7.

[0032] It is worth noting that a plurality of anti-skid grooves are provided on the outer side of the turntable 14 , and the anti-skid grooves can increase the friction of the turntable 14 , making the rotation of the turntable 14 more convenient.

[0033] In addition, a protective pad 15 is fixedly provided on the lower side of the L-shaped block 12. The protective pad 15 is made of soft material. The protective pad 15 can provide a certain degree of protection for the patient to avoid crushing the patient.

[0034] It must be mentioned that a tightening belt 19 is arranged on the outside of one group of L-shaped blocks 12, and a buckle 20 is fixedly arranged on the outside of the tightening belt 19, and an insertion frame 21 for docking with the buckle 20 is arranged on the outside of another group of L-shaped blocks 12. By setting the tightening belt 19, the patient can be further limited and fixed, thereby further improving the fixation effect on the patient.

[0035] Working principle: first, the patient lies supinely on the operating table, and then the turntable 14 is rotated according to the position that needs to be fixed. The turntable 14 drives the threaded rod 6 to rotate, and the threaded block 7 sleeved on the outside of the threaded rod 6 moves along the threaded rod 6 under the limiting action of the limiting groove 13. When the threaded block 7 moves, it drives the electric push rod 8 and the connecting rod 10 to move. When the connecting rod 10 moves, it drives the limit frame 11 and the L-shaped block 12 to move until the limit frame 11 moves to the appropriate position, and then the electric push rod 8 is turned on by an external power supply. The electric push rod 8 is shortened and drives the limit frame 11 to limit and fix the patient, and then the L-shaped block 12 is pushed downward so that the protective pad 15 fits the upper side of the patient, and then the butterfly nut 17 is tightened, and finally the buckle 20 is inserted into the slot 21, so that the patient can be fixed in all directions.
