Embodiment 2

[0057] On the basis of Embodiment 1, in this embodiment, we explain the pushing structure of the second auxiliary rod. combine Figure 5 and Figure 6 , the tail of the auxiliary rod 4 is connected with a push linkage rod 13, the tip of the clamping section has a through hole that can accommodate the extension of the auxiliary rod, the tail of the push linkage rod is provided with several racks 14, and the The rack 14 is cooperatingly provided with a gear 15, and also includes a rotating wheel 16. The rotating wheel 16 and the gear 15 are linked by a fixing piece. The said hand section has a through hole 17, and the fixing piece 18 passes through the through hole 17. , the rotating wheel 16 and the gear 15 are located on the outside and inside of the tweezers handle wall respectively.

[0058] By turning the rotating wheel, the gear can be driven to rotate, and then the gear rack matched with it can be driven to move, so that the auxiliary rod connected with the linkage rod ...

Embodiment 3

[0064] In this embodiment, further preferred reference Figure 7 , the front end of the auxiliary rod is provided with a plurality of pointed protrusions along the direction of the auxiliary rod, and these pointed protrusions are located on an arc rod.

[0065] At the same time, preferably, as Figure 7 The spikes shown in are equally spaced.

[0066] Applying this structure to Embodiment 1 or Embodiment 2, the dot-like gaps forming the capsular flap are evenly distributed, making it easier to tear off.

Abstract

The invention belongs to the field of medical apparatuses, and in particular relates to a pair of capsulorhexis forceps. The capsulorhexis forceps comprise a forceps handle which is composed of a handheld section and a clamping section. The forceps handle is of a hollow structure. The capsulorhexis forceps further comprise an auxiliary rod with a plurality of sharp bumps. The auxiliary rod is accommodated in the hollow forceps handle and stretches out of or shrinks in the accommodating space of the forceps handle through a through hole in the tip of the clamping section; and the sharp bumps are vertically fixed or formed on the auxiliary rod. By means of the auxiliary rod and the sharp bumps arranged on the auxiliary rod, a boundary of a capsula pedal needed can be formed on the surface ofthe crystal capsula smoothly, and the capsula pedal is obtained smoothly, so that a very good basis is created for follow-up CCC. The operating difficulty and risk are reduced, the success rate of CCC is improved, and furthermore, the operating quality and safety are improved.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to the field of ophthalmic surgical instruments, in particular to capsulorhexis forceps. Background technique [0002] Cataract is a common disease in ophthalmology, and it is also one of the main causes of vision loss in the elderly. At present, the most common clinical treatment method is phacoemulsification surgery, and the key to the operation is whether the continuous circular capsulorhexis (CCC) can be completed during the operation. A completed CCC means that the operation has been half successful. [0003] The starting point of making a capsulorhexis flap is the first step. The purpose of this action is to rupture the capsule and raise an edge that is easy to grip. It can be done with a cystotomy needle, capsulorhexis forceps, or a spear knife. Commonly, capsulorhexis forceps are used. The tip of the capsulorhexis forceps is actually edged. Use the tip of the capsulorhex...
