Description

Technical Field

[0001] The utility model relates to the technical field of posterior lens capsule protection, in particular to a posterior lens capsule protector. Background Art

[0002] During phacoemulsification of cataracts, the posterior lens capsule is very easy to rupture. At present, there is an occasional method to first remove part of the lens nucleus, then implant an artificial lens, and then remove the remaining lens nucleus and cortex. However, the diameter of the artificial lens is large and thick, which makes the operation inconvenient, the cortex under the artificial lens is difficult to remove, and the operation is easy to damage the artificial lens. At the same time, there is a nuclear chopping hook among the instruments used in ophthalmic cataract surgery, which is used to split the lens nucleus during phacoemulsification of cataracts and assist ultrasound. Therefore, the nuclear chopping hook is very important and widely used.

[0003] After searching, the posterior capsule protector of the lens (authorization announcement number: CN 208229045U), "The posterior capsule protection sheet is a rectangular thin sheet with an arc-shaped corner. It is implanted behind the lens nucleus and in front of the posterior capsule during phacoemulsification; the nucleus-splitting forceps used to place the protection sheet: the front parts of the two arc-shaped forceps in the sleeve are folded into right-angle ends, the right-angle hooks are downward, and the tips are blunt, which are used to split the nucleus, and can be opened and closed to clamp the protection sheet by the pressure button on the forceps handle. The four corners of the protection sheet of the artificial lens material are arc-shaped due to the chamfers. The advantage is that it protects the posterior capsule during the phacoemulsification stage to prevent the phacoemulsification head from colliding with the posterior capsule and causing the posterior capsule to rupture. The posterior capsule protection sheet must be placed in place with tweezers, and the lens nucleus must be split during phacoemulsification of cataracts. This design replaces the use of nucleus-splitting hooks and tweezers separately, reducing the time and infection risks caused by multiple in and out of the eye incision by the instrument."

[0004] Based on the above-mentioned related technologies, the applicant believes that the nucleus-chopping forceps in the above-mentioned technologies lack a storage mechanism. In actual use, when the nucleus-chopping forceps need to be stored after the operation on the patient, the nucleus-chopping forceps can only be placed in a storage tray. The nucleus-chopping forceps are always exposed to the air and are easily attached with bacteria, which shortens their service life and increases the risk of infection for patients. In response to the above problems, we have launched a posterior lens capsule protector. Utility Model Content

[0024] In the above technical solution, considering that the nuclear splitting forceps 5 lack a storage mechanism, the nuclear splitting forceps 5 are always exposed to the air, which is very easy to be attached with bacteria, shortening the service life and increasing the risk of infection for patients. In order to solve such problems, the specific operations are as follows:

[0025] Reference Figure 1 , Figure 2 and Figure 3 The staff rotates the roller 4, and the rotation of the roller 4 drives the threaded rod 3 to retract inside the telescopic groove 2 toward the inside of the holding part 1, thereby driving the nuclear splitting forceps 5 and the memory metal wire 6 to move in the direction close to the holding part 1, until the threaded rod 3 completely enters the storage hole 9, the nuclear splitting forceps 5 enters the telescopic groove 2, and the memory metal wire 6 enters the storage cover 10.

The diameter of the forceps rod of the nuclear splitting forceps 5 is 6 mm, and the length of the forceps rod of the nuclear splitting forceps 5 is 90 mm. By providing the support plate 13, the gripping portion 1 can be lifted upward to prevent the outer surface of the gripping portion 1 from directly contacting external objects.

[0028] Working principle: In actual use, use the nucleus-chopping forceps 5 to clamp the posterior capsule protection sheet and place it into the anterior chamber of the eye through the patient's incision. Then the nucleus-chopping forceps 5 enter the eye from another auxiliary incision, and then clamp the posterior capsule protection sheet and place the posterior capsule protection sheet in front of the posterior capsule membrane to protect the posterior capsule membrane. After the operation is completed, the staff needs to disinfect the protector and then store it. The operation method is that the staff rotates the roller 4, and the rotation of the roller 4 drives the threaded rod 3 to shrink inside the telescopic groove 2 toward the inside of the holding part 1, thereby driving the nucleus-chopping forceps 5 and the memory metal wire 6 to move in the direction close to the holding part 1 until the threaded rod 3 completely enters the inside of the storage hole 9, the nucleus-chopping forceps 5 enters the inside of the telescopic groove 2, and the memory metal wire 6 enters the inside of the storage cover 10.
