Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a cataract surgery capsulorhexis marker. Background Art

[0002] Capsulotomy is an important step in phacoemulsification surgery. It mainly involves using tools such as capsulotomy forceps to perform continuous circular capsulotomy in the center of the anterior capsule of the lens. By evenly retaining the anterior capsule around the eye, a well-centered circular capsulotomy is formed to ensure that the artificial lens subsequently implanted in the capsular bag obtains long-lasting and good centered stability.

[0003] After searching, the application with patent publication number CN219127027U disclosed a cataract surgery capsulotomy marker, including a support rod, an outer ring, multiple fixed rods and an inner ring; the support rod is connected to the outer ring, one end of the outer ring is connected to the first end of each fixed rod, and the second end of each fixed rod is connected to the inner ring. The inner ring is arranged on the outside of the outer ring, the center of the inner ring is coaxial with the center of the outer ring, and the diameter of the inner ring is smaller than the diameter of the outer ring, so that the staff can manually make indentations on the corneal surface, thereby improving the accuracy of the capsulotomy operation.

[0004] However, since medical staff manually move the support rod to align the outer ring with the patient's corneal margin and place the inner ring on the corneal surface so that the inner ring contacts the cornea, the medical staff have low stability and low safety during the manual operation. At the same time, since the medical staff cannot observe the condition of the eye with the naked eye when the inner and outer rings are pressed against the eye, it is inconvenient to operate and the accuracy of the inner ring placement is low.

[0005] Therefore, we proposed a capsulorhexis marker for cataract surgery. Utility Model Content

[0006] In view of the deficiencies of the existing technology, the utility model provides a cataract surgery capsulorhexis marker, which solves the problems of low operational stability and low operational accuracy of the existing devices.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A cataract surgery capsulorhexis marker comprises a base, the bottom surface of which is fixedly mounted with four sets of moving wheels;

[0008] An electric telescopic rod A is fixedly mounted on the top surface of the base, a top plate is fixedly mounted on the top of the electric telescopic rod A, a cylinder in a relatively opposite position is fixedly mounted on the bottom surface of the top plate, a fixed plate is sleeved on the output end of the cylinder, a support rod is fixedly mounted on the bottom surface of the fixed plate, the bottom end of the support rod is equipped with a fixed block, an outer ring sleeve of matching specifications is fixedly mounted on the bottom surface of the fixed block, three groups of electric telescopic rods B located inside the outer ring sleeve are fixedly mounted on the bottom surface of the fixed block, and an inner ring of matching specifications is fixedly mounted on the bottom end of the electric telescopic rod B;

[0009] The base is equipped with a processor inside, the top surface of the top plate is equipped with a display screen connected to the processor, an ultra-clear camera connected to the display screen is fixedly installed at the center of the bottom surface of the fixed block, and the bottom surface of the fixed block is fixedly equipped with a lighting lamp in an opposite position.

[0010] Preferably, the top surface of the top plate is equipped with a rotating shaft via a bearing, and a display screen is fixedly mounted on the top surface of the rotating shaft, so that the display screen can be rotated, thereby facilitating observation by medical personnel.

[0011] Preferably, a complementary lighting ring is fixedly mounted on the inner wall of the outer ring sleeve, which is opposite to the inner ring, so that the part blocked by the inner ring can be supplemented with lighting to improve the clarity.

[0012] Preferably, a threaded hole is provided on the top surface of the fixing block, and a thread of matching specifications is provided on the outer wall of the bottom surface of the support rod, so that the inner ring and the outer ring sleeve can be easily replaced.

[0013] Preferably, a control button is fixedly mounted on the top surface of the top plate, which makes it easy to control each part.

[0014] Preferably, the outer ring sleeve and the inner ring are equipped with pressure sensors to prevent excessive pressure caused by operational errors, thereby preventing damage to the eyes.

[0015] 1. This cataract surgery capsulorhexis marker is configured with an electric telescopic rod A, a cylinder, and an electric telescopic rod B. The electric telescopic rod A and the cylinder can drive the outer ring to move up and down, thereby aligning the outer ring with the edge of the cornea. The electric telescopic rod B then drives the inner ring to move downward and applies a little pressure to the cornea. Through mechanical operation, stability and safety are improved.

[0016] 2. At the same time, through the setting of display screen, ultra-clear camera and lighting, when the outer ring and inner ring are in contact with the cornea, the lighting will illuminate the eye, and the ultra-clear camera will transmit the image of the eye to the display screen for display, which is convenient for medical staff to observe and improve the accuracy of operation.
