Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic surgery, in particular to a novel adjustable capsule scissors. Background Art

[0002] Cataract capsule surgery is a common eye surgery. During the operation, the doctor needs to remove the capsule on the back of the lens in the eye. Generally, special capsule scissors or right-angle instruments are required for operation. Special capsule scissors can help ophthalmologists perform precise operations in a small space, remove the damaged capsule part, and protect other sensitive structures in the eye.

[0003] Currently, most common capsular scissors are of fixed right-angle design, which limits the doctor's flexibility. Especially when dealing with the capsule or cortex below the incision, right-angle instruments often have difficulty reaching the ideal cutting position and are not easy to operate, which may result in tearing off part of the capsule again, increasing the complexity and risk of the operation. In addition, right-angle capsular scissors may cause tearing of the membrane during shearing. In this case, the tear is easy to expand, which may lead to surgical complications and increase the patient's postoperative recovery time and discomfort.

[0004] Therefore, a new type of adjustable capsule scissors is needed to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide a novel adjustable capsular scissors to solve the problem that the existing capsular scissors mentioned in the above background technology are difficult to operate when processing the capsular membrane or cortex below the incision.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of adjustable capsule shears, comprising a handle body and a movable groove, wherein movable grooves are respectively provided on both sides of the top of the handle body, and each movable groove is equipped with a group of shearing pieces, a fixing buckle is fixed inside the movable groove, a knob is installed on the top of the shearing piece, and the knob is embedded in the fixing buckle, a pull rod is fixedly connected to the root of the shearing piece, a plurality of groups of protrusions are distributed on the inner wall of the fixing buckle, and a plurality of groups of teeth are distributed on the outer wall of the knob, and the teeth and the protrusions are engaged by friction.

[0007] Preferably, the number of the protrusions and the number of the teeth correspond, and the fixing buckle and the knob form a concentric circle structure.

[0008] Preferably, the shearing blades are hook-shaped, and the two groups of shearing blades are symmetrically distributed about the central axis of the handle body.

[0009] Preferably, storage grooves are respectively opened on both sides of the outer wall of the handle body, a group of hand blocks are hinged in each of the storage grooves, a magnetic attraction sheet is welded on the inner side of the hand blocks, and the magnetic attraction sheet and the storage grooves form a magnetic attraction structure.

[0010] Preferably, an anti-slip pattern is provided below the storage groove, and the anti-slip pattern is processed on the outer wall of the handle body.

[0011] Preferably, hinge rods are hinged on both sides of the inner wall of the handle body, hinge blocks are installed at the roots of the hinge rods, and the hinge rods are hinged to each other through the hinge blocks.

[0012] Preferably, the hinged rods are provided with two groups, a sliding rod is fixed at the right group of hinged rods, the end of the sliding rod is bent integrally to form a locking hook, and a groove is fixed at the left group of hinged rods, a locking hole is processed in the groove, the groove and the locking hole are buckled and fixed, and the hinged rods form an "X" shape structure.

[0013] Preferably, the handle body is formed by bending in one piece, and the handle body is made of stainless steel metal material.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the adjustable new capsular membrane scissors not only realize the adjustable shear blades, handle the hard-to-reach parts below the incision, prevent the membrane from tearing, avoid the operator's hand slipping, and reduce the doctor's fatigue during surgery, but also realize the safe closure and simple closing, which is convenient for storage, delivery and use;

[0015] (1) The scissors are equipped with cutting blades, a pull rod, a fixing buckle, and a knob. Accurate cutting of the capsule is crucial in cataract capsule surgery. By setting a cutting blade with an adjustable angle at the front end of the scissors, the pull rod is pulled during use, so that the fixing buckle and the knob can rotate relative to each other to overcome the friction and lock in place, thereby adjusting the cutting angle of the cutting blade, allowing ophthalmologists to more easily handle the hard-to-reach areas below the incision, preventing the membrane from tearing, and thus reducing the risk of postoperative complications.

[0016] (2) The scissors are provided with a handle, a hand guard, anti-slip patterns, and a magnetic sheet. An openable hand guard is provided on the outside of the handle. When the doctor holds the handle, he mainly holds the anti-slip pattern area, which provides a better grip. The hand abuts against the hand guard, which provides additional support, effectively avoiding the impact of hand slippage on the operation during the operation, ensuring that the ophthalmologist's hand is stable when performing delicate operations, reducing fatigue caused by long-term surgery, and increasing the safety of the operation;

[0017] (3) A locking structure is designed in the middle of the scissors by arranging an articulated rod, a sliding rod, a locking hook, a groove, and a locking hole. The handle body is squeezed hard, and the two sets of articulated rods are hinged to each other. The sliding rod slides at the locking hook. When it slides to the end, the groove hooks into the locking hole, so that the scissors can be safely closed when not in use. This not only facilitates the safe storage of surgical instruments, increases the durability of the scissors, and avoids accidental damage when not in use, but also ensures the quick and safe storage, transfer and retrieval of the capsular scissors in a tense surgical environment.
