Embodiment 1

[0022] The capsulorhexis forceps adopts the two-piece tweezers handle commonly used in clinical practice at present. Elastic deformation is produced, and the upper end 12 of the front and rear plates of the tweezers handle is firmly connected. The front and rear plates 8 and 9 of the tweezers handle are connected to the restricting module 7 below the middle to prevent the front and rear plates 8 and 9 of the tweezers handle from being too separated or closed too tightly. The lower ends of the front and rear pieces 8 and 9 of the tweezers are bent forward to form the upper and lower pieces 3 and 4 of the tweezers respectively. , 4 Utilize the elastic force of the metal to be close to each other, the cross section of the tweezers neck is horizontally oval, and the cross section of the contact surface of the upper and lower pieces 3 and 4 of the tweezers neck is in the shape of "﹀" or "︿", which can prevent the left and right misalignment . The front ends of the upper and lower...

Embodiment 2

[0024] The capsulorhexis forceps adopts the two-piece tweezers handle commonly used in clinical practice at present. Elastic deformation is produced, and the upper end 12 of the front and rear plates of the tweezers handle is connected. The front and rear plates 8 and 9 of the tweezers handle are connected to the restricting module 7 below the middle to prevent the front and rear plates 8 and 9 of the tweezers handle from being too separated or closed too tightly. The front and rear pieces 8 and 9 of the tweezers are bent backward near the lower end, and are hinged at the bend by a pin 13. From the pin 13 downwards, the front and back pieces 8 and 9 of the tweezers exchange front and rear positions, and the lower ends of the front and back pieces 8 and 9 of the tweezers are bent forward The upper and lower parts 3 and 4 of the tweezers neck are formed, and the thickness of the rear ends 5 and 6 of the upper and lower parts 3 and 4 of the tweezers neck is reduced, which is cond...

Embodiment 3

[0026] The capsulorhexis forceps adopts a two-piece tweezer handle, the front and rear pieces 8 and 9 of the tweezer handle are arranged front and back (in working condition), the upper part of the front and back pieces 8 and 9 of the tweezer handle is bent forward, and the thickness of the parts 10 and 11 near the upper end is small , is conducive to elastic deformation, and the upper ends 12 of the front and rear plates of the tweezers handle are firmly connected. The front and rear plates 8 and 9 of the tweezers handle are connected to the restricting module 7 below the middle to prevent the front and rear plates 8 and 9 of the tweezers handle from being too separated or closed too tightly. The lower ends of the front and rear pieces 8 and 9 of the tweezers are bent forward to form the upper and lower pieces 3 and 4 of the tweezers respectively. , 4 Utilize the elastic force of the metal to closely adhere to each other, the cross section of the tweezers neck is transversely...

Abstract

The invention relates to the field of medical health, and discloses a pair of capsulorhexis forceps used through a micro incision. The CCC is a key step in the process of a cataract phacoemulsification operation, and needs to be accomplished through the capsulorhexis forceps. At present, a pair of capsulorhexis forceps frequently used clinically can be opened and closed in a left-and-right mode so that only when the requirement that an incision is large enough is met, the capsulorhexis forceps can be fully opened. The pair of capsulorhexis forceps used through the micro incision comprises a forceps handle, a forceps neck and forceps tips, wherein the forceps handle is a front and rear piece press fit type handle, the forceps neck is of a structure with an upper piece and a lower piece, and the front end of the forceps neck is downwards bent to form the front forceps tip and the rear forceps tip. In the process of using the pair of capsulorhexis forceps, front-and-rear opening and closing movement of the forceps handle drives the upper piece and the lower piece of the forceps neck to carry out front-and-rear relative movement, then the front forceps tip and the rear forceps tip can carry out front-and-rear opening and closing movement, and the clamping motion and the release motion are achieved. The pair of capsulorhexis forceps can smoothly enter into an eye through the micro incision, operation is convenient, and daily maintenance is easy.

Description

technical field [0001] The invention relates to the medical and health field, and relates to tweezers used in ophthalmic surgery, especially when the surgical incision is relatively small, it can enter the eye through a tiny incision, and perform capsulorhexis smoothly. Background technique [0002] Cataract surgery has a history of more than 2,000 years. With the advancement of technology, cataract surgery has become increasingly minimally invasive. From the initial needle-pull cataract surgery, it gradually developed into intracapsular cataract extraction (incision greater than 10mm) in the 18th century, extracapsular cataract extraction (incision 5mm-10mm) in the 20th century, and phacoemulsification extracapsular cataract extraction (incision 3mm). ~3.5mm), the incision gradually narrowed. Especially since Charles Kelman invented phacoemulsification surgery in 1967, after more than 40 years of development, cataract surgery has entered the era of micro-incision (the size...
