Description

Technical Field

[0001] This invention relates to a retractor, and more particularly to an ophthalmic eyelid retractor. Background Technology

[0002] The eyelid, commonly known as the eyelid, is usually opened when treating ophthalmological patients. Generally, medical staff open the patient's eyelid before performing surgery. During the treatment, the medical staff manually open the patient's eyelid continuously. The operation time is long, which can easily cause soreness in the hands of the medical staff, affect the surgical treatment, and increase the difficulty of the medical staff's work.

The two ends of the second torsion spring 113 are respectively connected to the sixth bracket 111 and the fixed soft plate 114.

[0088] When it is necessary to open a patient's eyelids during ophthalmic surgery, this ophthalmic eyelid retractor can be used. First, the patient needs to lie on the pad 2 and rest their head on the support platform 3. Then, the lifting mechanism 6 is activated. The operation of the lifting mechanism 6 drives the opening mechanism 7, which in turn drives the opening rod 5, allowing the opening rod 5 to contact the patient's eyelids. Then, the medical staff needs to manually push the opening mechanism 7 to drive the opening rod 5, thereby opening the patient's eyelids. After the surgery, stop pushing the opening mechanism 7 and turn off the lifting mechanism 6.

[0089] Medical staff can start the servo motor 61. After the servo motor 61 is started, the output shaft of the servo motor 61 rotates, which drives the belt drive group 62 to drive the first lead screw 63 to rotate, which in turn drives the first connecting block 64 to move downward, causing the opening mechanism 7 components to move downward. Then, the medical staff can control the output shaft of the servo motor 61 to rotate in the opposite direction, which drives the belt drive group 62 to drive in the opposite direction, which in turn drives the first lead screw 63 to rotate in the opposite direction, which in turn drives the first connecting block 64 to move upward, causing the opening mechanism 7 components to move upward. Afterward, the servo motor 61 can be turned off.

[0090] When the first connecting block 64 moves downward, it drives the second connecting block 71 on the same side to move downward, thereby driving the second slide rail 72, the sliding block 73, and the first spring 74 to move downward. When the sliding block 73 moves downward, it drives the opening rod 5 on the same side to move downward, so that the opening rod 5 contacts the patient's eyelid. Then, the medical staff needs to manually pull the sliding block 73 to move in the opposite direction. The first spring 74 is stretched, thereby driving the opening rod 5 to move in the opposite direction. The movement of the opening rod 5 in the opposite direction can open the patient's eyelid, achieving the opening effect. When the medical staff releases the hand, the first spring 74 returns to its original position, causing the sliding block 73 to move in the opposite direction, thereby driving the opening rod 5 on the same side to move in the opposite direction. When the first connecting block 64 moves upward, it drives the second connecting block 71 on the same side to move upward, thereby driving the second slide rail 72, the sliding block 73, and the first spring 74 to move upward. When the sliding block 73 moves upward, it drives the opening rod 5 on the same side to move upward.

[0091] When the second connecting block 71 moves downward, it drives the second bracket 89 on the same side to move downward, thereby driving the nozzle 810 downward, which in turn causes the flexible water pipe 86 on the same side to move downward. Then, medical personnel can activate the micro cylinder 88. After activation, the telescopic rod of the micro cylinder 88 moves outward and contacts the first push plate 87 on the same side, causing the first push plate 87 to move outward, thereby driving the sliding baffle 84 to move outward. The second spring 85 is compressed, opening the outlet of the liquid outlet valve 83, allowing the medicine in the storage bottle 82 to pass through the flexible water pipe. Water flows through pipe 86 into nozzle 810 and is dripped into the patient's eyes to achieve the effect of medication. When the telescopic rod of miniature cylinder 88 moves inward and does not contact the first push plate 87 on the same side, the second spring 85 resets and drives the sliding baffle 84 to move inward, which can block the outlet of the liquid valve 83. At this time, medical staff can close miniature cylinder 88. When the second connecting block 71 moves upward, the second connecting block 71 drives the second bracket 89 on the same side to move upward, thereby driving the nozzle 810 to move upward, which in turn causes the soft water pipe 86 on the same side to move upward and reset.

[0092] When the first connecting block 64 moves downward and contacts the contact block 93 on the same side, the first connecting block 64 drives the contact block 93 on the same side to move downward, thereby driving the first sliding rod 92 to move downward. The third spring 94 is compressed. When the contact block 93 moves downward and contacts the rotating rod 96 on the same side, the rotating rod 96 swings outward, and the first torsion spring 97 twists and deforms. When the rotating rod 96 swings outward and contacts the pressing rod 98 on the same side, the rotating rod 96 causes the pressing rod 98 on the same side to move in the opposite direction, thereby driving the sliding block 73 on the same side to move in the opposite direction. No manual pushing is required. This saves manpower and achieves the squeezing effect. When the first connecting block 64 moves upward and does not contact the contact block 93 on the same side, the third spring 94 resets and drives the first sliding rod 92 to move upward, thereby driving the contact block 93 to move upward, so that the contact block 93 does not contact the rotating rod 96 on the same side. The first torsion spring 97 resets and drives the rotating rod 96 to swing inward, so that the rotating rod 96 does not contact the squeezing rod 98 on the same side. The first spring 74 resets and drives the sliding block 73 on the same side to move towards each other, thereby driving the squeezing rod 98 on the same side to move towards each other and reset.

[0093] Before surgery, medical staff can adjust the distance of the support column 4 according to the distance between the patient's eyes. If the distance between the patient's eyes is small, the medical staff can manually hold the handle and turn it, thereby driving the second lead screw 106 to rotate, which in turn causes the fourth connecting block 107 to move to the right. When the fourth connecting block 107 moves to the right, it drives the second push plate 108 to move to the right. As the fourth spring 109, which is in a compressed state, returns to its original position, it causes the support column 4 to move in the opposite direction, which in turn causes the second sliding rod 102 to move in the opposite direction, thus adjusting the distance between the front and rear supporting rods 5 and reducing the distance between the supporting rods 5 on both sides. Then, the medical staff can stop the handle 105. After the surgery, the medical staff can manually hold the handle and turn it in the opposite direction, thereby driving the second lead screw 106 to rotate in the opposite direction, which in turn causes the fourth connecting block 107 to move to the left. When the fourth connecting block 107 moves to the left, it drives the second push plate 108 to move to the left, thus causing the second sliding rod 102 to move in the opposite direction. The moving rod 102 moves in the opposite direction, which in turn drives the support column 4 to move in the opposite direction, causing the fourth spring 109 to be compressed. If the distance between the patient's eyes is large, the medical staff can reverse the handle 105, which causes the second lead screw 106 to rotate in the opposite direction, causing the fourth connecting block 107 to move to the left, which in turn drives the second push plate 108 to move to the left. When the second push plate 108 moves to the left, the second sliding rod 102 moves in the opposite direction, which in turn causes the support column 4 to move in the opposite direction. The fourth spring 109 continues to be compressed, which can adjust the opening rods 5 on both sides, making the distance between the opening rods 5 on both sides larger. After the operation, the medical staff can use the handle 105, which drives the second lead screw 106 to rotate, which in turn drives the fourth connecting block 107 to move to the right, which in turn drives the second push plate 108 to move to the right. When the second push plate 108 moves to the right, the fourth spring 109, which is still under compression, returns to its original state, which drives the second sliding rod 102 to move in the opposite direction, which in turn causes the support column 4 to move in the opposite direction and return to its original state.

[0094] When the patient rests their head on the fixed soft plate 114, the weight of the patient's head causes the fixed soft plate 114 to move downward, thereby causing the rotating shaft 112 to rotate and the second torsion spring 113 to twist and deform. When the patient gets up after the operation, due to the reduction of weight, the second torsion spring 113 returns to its original position, causing the fixed soft plate 114 to move upward and return to its original position.

[0095] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
