Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to a patient prone table for ophthalmic surgery. Background Art

[0002] With the development of modern medical technology, the precision and complexity of ophthalmic surgery are constantly improving, especially for microsurgery and laser surgery, which have extremely high requirements on the patient's body position. In order to ensure the effectiveness of the surgery, the patient needs to maintain a stable prone position for a long time during the operation. Although this position can provide the surgeon with an ideal surgical field of view, for the patient, maintaining this position for a long time often causes discomfort or even health problems, such as pressure in the chest, neck and lower limbs, difficulty breathing and poor blood circulation.

[0003] In the prior art, the operating table usually adopts a fixed design, which is difficult to meet the precise adjustment requirements of the patient's body position in different ophthalmic surgeries. In addition, individual differences in patients (such as height, weight, health status) and different types of surgeries (such as cataracts, glaucoma, retinal detachment, etc.) put higher requirements on the design of the prone table. Existing operating tables often lack flexibility and it is difficult to provide a comfortable prone experience and suitable surgical operating conditions at the same time. Summary of the invention

[0010] Preferably, the outer wall of the second horizontal plate is rotatably connected to the first rotating plate, the outer wall of the first rotating plate is rotatably connected to the second rotating plate, and the right outer wall of the second rotating plate is fixedly connected to the lower surface of the adjustment frame.

[0011] Preferably, a fourth pulley is rotatably connected to the left outer wall of the second rotating plate, a second sliding frame is fixedly connected to the upper surface of the second transverse plate, and an outer wall of the fourth pulley is slidably connected to the inside of the second sliding frame.

[0015] Working principle: When the device needs to be used, first turn on the first electric push rod on the inner wall of the slide plate. When the first electric push rod starts running, it will push the push-pull plate at its output end to move. When the first electric push rod pushes the push-pull plate to move, it will rotate itself. When the push-pull plate moves, it will drive the second lifting plate on its outer wall to rotate. When the second lifting plate rotates, it will drive the third pulley on its outer wall to rotate. When the third pulley is driven by the second lifting plate to rotate, its outer wall will slide on the inner wall of the first slide frame. At the same time, the second lifting plate will drive the first lifting plate on the outer wall of the connecting shaft to rotate. When the third pulley is driven by the second lifting plate to rotate, its outer wall will slide on the inner wall of the first slide frame. At the same time, the second lifting plate will drive the first lifting plate on the outer wall of the connecting shaft to rotate. When the first lifting plate is driven by the second lifting plate to rotate, the second pulley on its outer wall will be driven to rotate. When the second pulley rotates, its outer wall will slide on the inner wall of the base. When the first lifting plate rotates, the connecting plate on its outer wall will be driven to slide. When the connecting plate slides, the slide plate on its lower surface will be driven to slide. The outer wall of the slide plate will slide inside the base. When the connecting plate slides, the first pulley on its outer wall will be driven to rotate. At the same time, when the first pulley rotates, its outer wall will slide on the inner wall of the base. Finally, the first lifting plate and the second lifting plate rotate at the same time. When the patient lies on the prone table and needs to adjust the angle and height of the front and rear bed boards, the second electric push rod on the inner wall of the outer frame is first turned on. When the second electric push rod starts to run, it will drive the adjusting rod at its output end to rotate. At the same time, the second electric push rod itself will also rotate due to the pressure. When the outer wall of the adjusting rod rotates on the inner wall of the supporting piece, it will push the adjusting frame on its outer wall to adjust the angle. When the outer wall of the adjusting frame rotates on the inner wall of the outer frame, it will drive the second rotating plate on its lower surface to rotate. When the second rotating plate rotates, it will drive The fourth pulley on its outer wall rotates, and when the fourth pulley rotates, its outer wall will slide inside the second sliding frame. At the same time, the second rotating plate will also drive the first rotating plate of its outer wall to rotate. The first rotating plate rotates on the outer wall of the second horizontal plate to support the second rotating plate. When the adjustment frame drives the prostrate board to adjust to a suitable angle, the hydraulic rod specified on the upper surface of the support plate is opened according to the needs of the patient. When the hydraulic rod is running, it will drive the lifting bed board specified at its output end to be raised and lowered, so that not only the angle of the upper body can be adjusted according to the needs of the patient, but also the height of the designated bed board for the lower body can be adjusted according to the needs of the patient.

[0016] The present invention provides a patient prone table for ophthalmic surgery, which has the following beneficial effects:

[0017] 1. The present invention pushes the push-pull plate through the first electric push rod, the push-pull plate drives the second lifting plate to rotate, the second lifting plate drives the third pulley to slide, the second lifting plate drives the first lifting plate to rotate, the first lifting plate drives the second pulley to slide, the first lifting plate drives the connecting plate to slide, the connecting plate drives the slide plate to slide, the connecting plate drives the first pulley to slide, and finally the first lifting plate and the second lifting plate rotate at the same time to push the supporting plate to rise and fall, thereby driving the entire prone table to rise and fall. Different ophthalmic surgeries require different patient positions, and the lifting prone table can be flexibly adjusted to meet the needs of various surgeries.

[0018] 2. The present invention drives the adjusting rod to rotate through the second electric push rod, the adjusting rod pushes the adjustment of the angle of the adjusting frame, the adjusting frame drives the second rotating plate to rotate, the second rotating plate drives the fourth pulley to slide, and the second rotating plate drives the first rotating plate to rotate, so as to adjust the angle of the upper body to reduce the pressure on the patient's chest, neck and face, relieve the discomfort caused by long-term surgery, and help patients better maintain the body position required for surgery.

[0019] 3. The present invention opens a hydraulic rod designated on the upper surface of the support plate, and the hydraulic rod drives the designated lifting bed board at its output end to perform lifting and adjustment. Prolonged prostrate posture may lead to obstructed blood circulation or muscle tension in the lower limbs. Adjusting a bed board in the lower body can reduce pressure on the leg and buttocks area, and help relieve numbness, soreness or other discomfort in the lower limbs.

[0020] 4. The present invention combines the lifting function with the adjustment of the upper body angle, so that the doctor can adjust the patient to the ideal height and posture according to the surgical requirements, thereby obtaining the best viewing angle and operating space, especially in micro-ophthalmic surgery, which helps to improve the accuracy of the surgery.
