Description

A kind of ophthalmic 23G light-guiding type core splitting hook

Technical field

This utility model belongs to technical field of medical instruments, particularly relates to a kind of ophthalmic 23G light-guiding type core splitting hook.

Background technology

Modern ultrasound emulsifying operation generally acknowledged is used for the treatment of one of cataractous Main Means.In operation process, for harder nucleus lentis block, need to use core splitting hook to be split into multiple maneuverable fritter, realize pouch internal emulsification, effectively reduce ultrasonic energy, reduce the damage to eye inner tissue, improve operation safety and efficiency.

At present, core splitting hook employed both at home and abroad mainly contains following three kinds:

1. Nagaharachopper and southern style hook, its front end hook neck is right-angle bending, is about 1.5mm ~ 2mm, and outer end circle is blunt, in blade inside hook segment, is usually used in level and splits core;

2. vertically split core core splitting hook, its hook neck is right-angle bending, and head end is sharp-pointed, is beneficial to and vertically splits core, and part front end becomes spade-type blade;

3. koch core splitting hook (kochchopper), hook neck is right-angle bending, is about 1.5mm ~ 2mm, and outer end circle is blunt, without blade, can take into account level or vertically split core.

But, when adopting above-mentioned three kinds of core splitting hooks to carry out cataract surgery, all adopt exterior lighting, for the complicated cataract operation of the refractive media muddinesses such as corneal leukoma, because the light transmission of refractive media is poor, cause the illuminating effect of ophthalmic often not good, the operating difficulty virtually increased, also make the occurrence probability of intraoperative compliaction significantly increase, reduce operation safety.

Utility model content

For prior art Problems existing, this utility model provides a kind of ophthalmic 23G light-guiding type core splitting hook, hook neck possesses luminous power, ophthalmic illumination can be realized in operation process, improve refractive media light transmission, thus reduction operating difficulty, reduce the occurrence probability of intraoperative compliaction, finally improve operation safety.

To achieve these goals, this utility model adopts following technical scheme: a kind of ophthalmic 23G light-guiding type core splitting hook, comprise hook neck, handle and wire, described hook neck rear end is connected with wire one end by handle, the wire other end connects light guide connector, and wire is cut machine by light guide connector and glass and is connected; Described wire is made up of the 23G optical fibers being coated with gelatinous layer; Described hook neck is made up of the 23G optical fibers being coated with steel layer.

Described hook neck at right angles bends, and diameter is 0.5mm, and length is 1.5mm ~ 2mm, and outer end circle is blunt, without blade.

The beneficial effects of the utility model:

This utility model can realize ophthalmic illumination in operation process, avoids the operation of many blindnesses, reduces the damage to eye inner tissue, be particularly suitable for the complicated cataract operations such as corneal leukoma, microcoria, keratoplasty.

Cannot the complicated cataract operation of clear observation ophthalmic for what cause because of cornea condition difference, continuous curvilinear capsulotomy can being completed by assist physician by this utility model, preventing, when carrying out crystal nuclear emulsifying, the complication such as Poster capsulorhexis occur.

When microcoria, mature cataract, cortical cataract carry out occurring that optical fundus reflection to red light is not good when splitting core operation, carry out ophthalmic illumination by this utility model, accurately can point out capsule position and each layer tissue boundary after doctor, the generation of prevention intraoperative compliaction.

Accompanying drawing explanation

Fig. 1 is a kind of ophthalmic 23G light-guiding type core splitting hook structural representation of the present utility model;

In figure, 1-hook neck, 2-handle, 3-wire, 4-light guide connector.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.

As shown in Figure 1, a kind of ophthalmic 23G light-guiding type core splitting hook, comprises hook neck 1, handle 2 and wire 3, and described hook neck 1 rear end is connected with wire 3 one end by handle 2, and wire 3 other end connects light guide connector 4, and wire 3 is cut machine by light guide connector 4 and glass and is connected; Described wire 3 is made up of the 23G optical fibers being coated with gelatinous layer; Described hook neck 1 is made up of the 23G optical fibers being coated with steel layer.

Described hook neck 1 at right angles bends, and diameter is 0.5mm, and length is 1.5mm ~ 2mm, and outer end circle is blunt, without blade.

Below in conjunction with accompanying drawing, a use procedure of the present utility model is described:

First the light guide connector 4 of wire 3 end being inserted glass cuts in the photoconduction port of machine, light is cut machine by glass and is exported to hook neck 1, now hook neck 1 realizes luminescence, then holding handle 2 and controlling hook neck 1 enters in anterior chamber by cornea side otch, now carry out ophthalmic illumination by hook neck 1, next carry out cortex separation successively by hook neck 1, core is separated, cut and rotate, complete the collection of core sheet.

Scheme in embodiment is also not used to limit scope of patent protection of the present utility model, does not allly depart from the equivalence that this utility model does and implements or change, and is all contained in the scope of the claims of this case.
