Description

A kind of core splitting hook

Technical field

The utility model relates to the field of medical instrument technology, and in particular to a kind of core splitting hook.

Background technique

Cataract is common blinding eye disease, and operation is unique effective means of current treatment cataract, domestic at present Mainstream operation is Phacoemulsification and intraocular lens implantation.The mode of Phacoemulsification and intraocular lens implantation: After doing cut-out of limbus corneae, row anterior lens capsule continuous curvilinear capsulotomy, water separates crystal nuclear, splits core, Phacoemulsification separation Crystal nuclear, perfusion suction lens cortex, implantable artificial crystal.The core of the operation is muddy lenticular ultrasonic emulsification, The core of ultrasonic emulsification operation is the separation of lens nucleus.

Current splits kernel mode are as follows: using ultrasonic syringe needle cutting on lens nucleus, a word or cross, under vacuum suction Lens nucleus is divided into several fritters by the separation of row lens nucleus, and convenience for ultrasonic emulsification is sucked out.Cataract operation need to use split core Hook, common core splitting hook is L-type core splitting hook at present, is had the problem that using this core splitting hook

1. when encountering complicated cataract or fortuitous event, such as: capsulorhexis fails (too small, capsular rupture), is traumatic white Cataract or glaucoma etc., conventional core splitting hook, which often can not be successfully, at this time is operated, and operating difficulty increases.

2. encountering the patient that patient's suspensorium is bad or cyst membrane is relatively thin, conventional core splitting hook is easy to damage cyst membrane, causes to perform the operation Failure.

3. when encountering the cataract of 5 grades and the above hardness, conventional core splitting hook can not rive crystal nuclear, and operation is caused to lose It loses, or big incision cataract surgery of changing one's profession.

Utility model content

The purpose of this utility model is to provide a kind of core splitting hooks, to solve the problems, such as that existing core splitting hook application range is small.

The technical solution that the utility model solves above-mentioned technical problem is as follows:

A kind of core splitting hook, comprising: the neck of hook；The both ends of the neck of hook are equipped with coupler body；Coupler body includes sequentially connected linkage section, folding Curved segment and head, and be in bending-like between linkage section and bending section, it is formed between bending section and head by bending hook-shaped；Even Section is connect to connect with the neck of hook；One of head is equipped with blade in inside, another head is equipped with blade on the outside.

The utility model is equipped with coupler body at the both ends of the neck of hook, and the blade in two coupler bodies has different directions, The function of core splitting hook is increased, suitable one end can be selected to be operated according to the eye and head situation of patient, is grasped Make flexibly, to improve and split core efficiency, expand the operative indication range of cataract operation.

Further, the extending direction of above-mentioned linkage section and the extending direction of the neck of hook are consistent.

Further, the angle between above-mentioned linkage section and bending section is 90 ° -150 °.

Further, direction bending of the above-mentioned head to the separate neck of hook.

Further, the angle between above-mentioned head and bending section is 60 ° -120 °.

Further, the angle between above-mentioned blade two sides is 80 ° -100 °.

The knife edge angular of the utility model is larger, will not be too sharp keen, can avoid damage to the cyst membrane of patient.

Further, changeover portion is equipped between the above-mentioned neck of hook and linkage section.

Due to being relatively large in diameter for the hand-held neck of hook, coupler body each section diameter for operation is smaller, and changeover portion is used for hook Transition between handle and linkage section.

Further, the lateral surface of the above-mentioned neck of hook is equipped with annular knurl.

The utility model has the function of anti-skidding in the annular knurl that neck of hook lateral surface is arranged.

The utility model has the following beneficial effects:

(1) the utility model is respectively provided with coupler body at the both ends of the neck of hook, can select to close according to the eye and head situation of patient Suitable one end is operated, and promotes the flexibility ratio of operation.

(2) blade in the utility model on two coupler bodies has different directions, respectively in knife outside blade in side and side Sword improves and splits core efficiency, expands the operative indication range of cataract operation.

(3) coupler body at the utility model neck of hook both ends has different modes of operation, and operator's both hands respectively hold one end, coordinates Effect makes to split kernel mode more convenient.

(4) the core splitting hook structure of the utility model is simple, and convenient for production, cost is smaller.
