Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an eye surgery auxiliary table. Background Art

[0002] Common ophthalmic diseases include central serous retinopathy, dry eyes, sympathetic ophthalmia, night blindness, amblyopia, astigmatism, trachoma, cataracts, glaucoma, floaters, etc. Surgery can treat, recover or completely cure these ophthalmic diseases. Generally, the surgery requires the cooperation of the patient with the help of an eye surgery assisting table.

[0003] When a conventional eye surgery auxiliary table is in use, after the head of the patient to be operated on is fixed, if the patient's head deflection needs to be controlled during the operation, the fixing effect of the fixing mechanism on the head needs to be released first in order to control the deflection of the head, and the fixing mechanism needs to be locked again later, which is cumbersome to operate, and it is difficult to control the locked fixing mechanism to directly drive the patient's head deflection. At the same time, when performing eye surgery, the doctor's hands are suspended above the patient's eyes for a long time to operate the surgical instruments, which is very tiring. Summary of the invention

[0004] The purpose of the present invention is to solve the problems that the conventional eye surgery auxiliary table is inconvenient to adjust the deflection of the patient's head after fixing it and cannot relieve the doctor's hand fatigue when in use. The present invention provides an eye surgery auxiliary table.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention controls the extension of the telescopic push rod to push the cable downward after the patient's head is resting on the pillow table. The cable applies pressure to the guide roller three, and the elastic rods on both sides are thereby driven to move toward each other, driving the flexible side guards to fit the cheeks to limit the position of the patient's head. In the process of the flexible side guards fitting the cheeks, the height of the flexible side guards continues to decrease, so that the flexible side guards can be at a suitable height according to the size of the patient's head. This not only improves the comfort of use, but also ensures the stability of fixing the patient's head, which is convenient for the doctor to operate safely. At the same time, the pillow table is deflected by adjusting the worm gear to drive the worm gear segment, so that the deflection of the fixed head of the patient can be controlled to be fine-tuned, which is convenient for eye surgery.

[0021] 2. The present invention controls the flexible side guards on both sides to move toward each other to fix the patient's head, and the auxiliary support plate automatically deflects forward to a horizontal position.

DETAILED DESCRIPTION

[0031] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] An eye surgery assisting table according to a preferred embodiment of the present invention will be described in detail below.

[0033] like Figure 1-Figure 8 As shown, an eye surgery auxiliary table includes an operating table 1, a U-shaped groove plate 2 is fixedly connected to the rear end of the operating table 1, an arc rail 21 is arranged on the top of the U-shaped groove plate 2, guide rollers 22 are rotatably connected to the left and right sides of the inner cavity of the U-shaped groove plate 2, a cable 23 is movably sleeved between the guide rollers 22, and a telescopic push rod 24 is fixedly installed in the middle of the inner cavity of the U-shaped groove plate 2;

[0034] A pillow platform 3 is slidably mounted on the upper end of the arc rail 21, and a bottom-connected card slot is opened on the left and right sides of the pillow platform 3. The bottom of the card slot is connected to two symmetrical guide rollers 2 31 that rotate along the central direction of the pillow platform 3. Elastic rods 32 are slidably mounted on the left and right sides of the card slot. A guide roller 33 is rotatably mounted on the bottom of the elastic rod 32. The cable 23 is movably sleeved with the guide roller 2 31 and the guide roller 3 33 respectively.

[0035] A flexible side stopper 39 is fixedly connected to the side wall of the elastic rod 32 near the center of the pillow platform 3, a top guard plate 4 is fixedly connected to the top rear side of the pillow platform 3, an arc-shaped worm gear segment 5 is provided on the front side of the pillow platform 3, an adjusting worm 25 meshing with the worm gear segment 5 is rotatably connected to the front end of the U-shaped groove plate 2, an auxiliary support plate 65 is provided above the top guard plate 4, an operating port 68 is opened at the rear end of the auxiliary support plate 65, and an adjusting screw 64 capable of controlling the downward movement of the auxiliary support plate 65 is threadedly connected to the rear end of the top guard plate 4.

[0036] When in use, by controlling the patient to lie flat on the operating table 1 with his head centered on the pillow table 3, the telescopic push rod 24 is controlled to extend and push the cable 23 downward, and the cable 23 is guided by the guide roller 1 22 and the guide roller 2 31 to apply pressure to the guide roller 33, thereby pulling the elastic rods 32 on both sides to compress the elastic potential energy and move toward each other, and then the flexible side guards 39 on the elastic rods 32 gradually approach and fit the patient's cheeks. When the elastic rods 32 drive the flexible side guards 39 to completely fit the patient's cheeks, the telescopic push rod 24 is controlled to stop extending and outputting, and the patient's head is automatically limited to ensure stability. In the process of the flexible side guards 39 fitting the cheeks, their height continues to decrease, so that the flexible side guards 39 can be ensured to be at a suitable height according to the size of the patient's head. That is, when the patient's head is relatively large, the width of the head is wider and the height is higher, and the corresponding flexible side guard 39 moves a shorter distance to fit the patient's cheeks, and the distance the top of the flexible side guard 39 drops is shorter, thereby ensuring that the patient's cheeks are sufficiently The covering limit, when the patient's head is relatively small, the width of the head is small and the height is low. The corresponding flexible side block 39 moves a large distance to fit the patient's cheek, and the top of the flexible side block 39 drops a long distance, thereby ensuring sufficient covering limit for the patient's cheek, not only improving the comfort of use, but also ensuring the stability of the fixation of the patient's head, which is convenient for the doctor to operate safely. At the same time, the worm gear 25 is adjusted to drive the worm gear segment 5 to control the deflection of the pillow table 3, which can control the deflection of the fixed head of the patient for fine adjustment, which is convenient for eye surgery. In addition, when the flexible side blocks 39 on both sides are controlled to move toward each other to fix the patient's head, the auxiliary support plate 65 automatically deflects forward to the horizontal, and after the flexible side blocks 39 are positioned, the control adjustment screw rod 64 drives the auxiliary support plate 65 to move down above the patient's face, so that when the doctor performs eye surgery, the auxiliary support plate 65 provides hand support and the operation port 68 is used for surgical operations, which is convenient for surgical operations and saves physical effort.

[0037] In this embodiment, the telescopic end of the bottom of the telescopic push rod 24 is movably sleeved on the cable 23, and vertical grooves for the cable 23 to be movably inserted are provided on both sides of the telescopic end of the bottom of the telescopic push rod 24;

[0038] The bottom of the U-shaped groove plate 2 and the bottom of the operating table 1 are both provided with a coaxial through groove, the size of the through groove is the same as the size of the telescopic end of the bottom of the telescopic push rod 24, and the upper side port of the through groove on the U-shaped groove plate 2 is rounded.

[0039] Specifically, when the telescopic push rod 24 is extended to push the cable 23 downward, the telescopic end at its bottom passes through the through slots on the U-shaped slot plate 2 and the operating table 1, and the cable 23 pulled out through the through slot is embedded in the vertical slots on the left and right sides of the telescopic end at the bottom of the telescopic push rod 24. Combined with the rounded corners of the upper side port of the through slot on the U-shaped slot plate 2, the cable 23 can be stably and reliably driven by the telescopic push rod 24 to slide.

[0040] In this embodiment, an elastic torque tube 35 is slidably sleeved on the top of the elastic rod 32, and a sliding roller 38 is rotatably connected to the top of the elastic torque tube 35. The flexible side block 39 is movably sleeved on the periphery of the sliding roller 38 and extends to be fixedly connected to the side wall of the pillow platform 3. A hinge rod 37 is movably connected between the elastic torque tube 35 and the side wall of the pillow platform 3. Specifically, the elastic torque tube 35 automatically lifts the flexible side block 39 using the sliding roller 38 under the action of its own elastic force. When the elastic rod 32 moves to the left or right, the elastic torque tube 35 automatically moves upward or downward accordingly under the restraining action of the hinge rod 37, so that the height of the flexible side block 39 can be automatically adapted to the heads of patients of different sizes.

[0041] In this embodiment, the elastic force of the elastic torque tube 35 is smaller than the elastic force of the elastic rod 32, and the elastic torque tube 35 is in a stretched state and has a tendency to move downward. Specifically, by utilizing the effect that the elastic torque tube 35 has a tendency to move downward, when the elastic rods 32 on both sides move toward each other, the elastic torque tube 35 can stably cooperate with the hinge rod 37 to automatically move downward, thereby adjusting the deformation of the flexible side block 39.

[0042] In this embodiment, the side wall of the elastic torque tube 35 away from the hinge rod 37 includes a protrusion 36 that movably interferes with the inner wall of the flexible side block 39. Specifically, the protrusion 36 on the side wall of the elastic torque tube 35 is utilized so that when the flexible side block 39 is deformed accordingly under the drive of the elastic torque tube 35, the flexible side block 39 can fit the patient's cheek and appropriately form a protruding portion that is snapped near the cheek bone, thereby ensuring the stability of the head fixation.

[0043] In this embodiment, two symmetrical telescopic rods 6 are rotatably connected to the rear side of the pillow platform 3, a bevel gear 62 is fixedly connected to the top of the telescopic rod 6, an axis plate 63 is rotatably connected between the tops of the two telescopic rods 6, an auxiliary support plate 65 is rotatably connected to the top of the axis plate 63, and the left and right sides of the auxiliary support plate 65 are rotatably connected to bevel gear 2 66 meshing with bevel gear 1 62, bevel gear 2 66 is coaxial with the auxiliary support plate 65, and a volute spring 67 is fixedly connected between bevel gear 2 66 and the auxiliary support plate 65.

[0044] A T-shaped rack 34 meshing with the transmission gear 61 is fixedly connected to the rear end of the bottom of the elastic rod 32 .

[0045] The telescopic rod 6 includes two parts that rotate synchronously up and down, and a transmission gear 61 is fixedly connected to the bottom of the telescopic rod 6.

[0046] Specifically, when the elastic rods 32 on both sides move toward each other, the T-shaped racks 34 on both sides are driven to move toward each other synchronously, thereby meshing and driving the transmission gear 61 to rotate, the transmission gear 61 drives the telescopic rod 6 to rotate, the telescopic rod 6 drives the bevel gear 1 62 to make the bevel gear 2 66 rotate, and the auxiliary support plate 65 is driven by the bevel gear 2 66 to deflect forward under the action of the volute spring 67. When the elastic rod 32 moves to drive the flexible side baffle 39 to fix the patient's head, the bevel gear 2 66 needs to rotate multiple circles. Therefore, after the auxiliary support plate 65 deflects forward half a circle and becomes horizontal, the volute spring 67 continuously deforms and accumulates force to ensure the stability of the auxiliary support plate 65, thereby ensuring the reliability of the use of the auxiliary support plate 65.

[0047] In this embodiment, the top end of the adjusting screw rod 64 is rotatably connected to the lower wall of the shaft plate 63. Specifically, after the flexible side stop 39 is positioned, the adjusting screw rod 64 is controlled to rotate and drive the shaft plate 63 to move downward, so that the auxiliary support plate 65 moves down to above the patient's face, thereby making it easier for the doctor to use the auxiliary support plate 65 to provide hand support when performing eye surgery and use the operating port 68 to perform surgical operations, thereby facilitating surgical operations and saving physical effort.

[0048] In this embodiment, arc grooves corresponding to the T-shaped rack 34 are provided on both the left and right sides of the rear wall of the U-shaped groove plate 2. Specifically, the arc grooves are used to facilitate the T-shaped rack 34 to follow the deflection movement of the pillow platform 3.

[0049] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
