Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary appliances, and in particular relates to an adjustable head position fixing device for ophthalmic surgery. Background Art

[0002] When performing eye surgery on a patient, if the patient's head moves unconsciously during the operation, it will affect the doctor's surgical progress. Therefore, the patient's head needs to be fixed before the operation to prevent the patient's head from moving during the operation. After searching, it was found that the application number "202220587534.9" discloses "an adjustable ophthalmic surgical head position fixator", which records "including an adjustment plate, an angle adjustment component and a head fixing component. The top of the adjustment plate is equipped with a head fixing component, and the side wall of the adjustment plate is equipped with an angle adjustment component. The angle adjustment component includes an arc plate, an electric telescopic rod, a first vertical plate, a second vertical plate and a support plate. The arc plate is installed on the outer wall of the adjustment plate. The side wall of the arc plate is rotatably connected to the telescopic end of the electric telescopic rod through a pin shaft. The end of the electric telescopic rod The first vertical plate is rotatably connected with the first vertical plate through a pin shaft, the second vertical plate is installed on a side of the adjustment plate away from the arc plate, and the side walls of the second vertical plate are rotatably connected with a support plate through a pin shaft. When in use, the above-mentioned fixer drives the screw rod to rotate by a driving motor, so that the first clamping plate and the second clamping plate can fix the patient's head. However, the above-mentioned fixer still has certain shortcomings when in use: firstly, although the patient's head can be quickly fixed by the motor-driven screw rod, for patients with different head circumferences, the motor-driven screw rod method is not enough to quickly fix the patient's head. At the same time, after the first clamping plate and the second clamping plate fix the patient's head, the patient's head cannot move left and right, but can still perform simple nodding activities. Therefore, there is still a situation in which head activities affect the operation during the operation. Utility Model Content

After changing the position of the adjusting rod 62 in the square sleeve 61 so that the support pad 65 is close to the patient's chin, tightening the second locking bolt 68 can fix the position of the adjusting rod 62, thereby stabilizing the patient's chin.

[0033] In this embodiment, guide grooves 7 are formed on both inner walls of the slide groove 3 , and guide blocks 8 are fixedly connected to both sides of the moving block 53 , and the guide blocks 8 are slidably installed in the guide grooves 7 .

[0034] Specifically, the guide block 8 cooperates with the guide groove 7 to guide the moving direction of the moving block 53 , thereby improving the stability of the movement of the clamping member 54 .

[0035] In this embodiment, one end of the moving rod 63 located in the moving tube 64 is fixedly connected to the limiting block 9, the inner wall of the moving tube 64 is provided with a sliding groove 10, the limiting block 9 is slidably installed in the sliding groove 10, and the size of the moving rod 63 matches the internal size of the moving tube 64.

[0036] Specifically, the limit block 9 cooperates with the sliding groove 10 to prevent the end of the moving rod 63 from being separated from the moving tube 64 .

[0037] In this embodiment, a neck pillow 11 is installed at the front end of the installation shell 1 .

[0038] Specifically, the provided neck pillow 11 can support and lift the patient's neck, thereby reducing the discomfort caused by the patient's neck being suspended in the air.

[0039] In this embodiment, the support pad 65 is a silicone pad.

[0040] Specifically, the support pad 65 made of silicone pad can improve the patient's comfort when fixing the patient's chin.

[0041] Working principle: After placing the device on the operating table, the patient's head is placed on the surface of the headrest 4. The neck pillow 11 provided can support the patient's neck to prevent the patient's neck from being suspended in the air and causing discomfort. Then, by rotating the rotating wheel 52, the two-way screw rod 51 drives the two moving blocks 53 to move toward each other. At this time, the clamping member 54 can clamp the patient's head. At the same time, the two moving rods 63 move into the moving tube 64. Then, the square sleeve 61 is rotated, and then the position of the adjusting rod 62 is adjusted to make the support pad 65 fit the patient's chin. After that, the first locking bolt 67 and the second locking bolt 68 are tightened respectively. In this way, the patient's head can be stably fixed to prevent the patient from having unconscious activities during the operation that affect the progress of the operation.
