Technical field

The invention belongs to ophthalmic surgical device technical fields, and in particular to a kind of device for the implantation of ophthalmology drainage tube.

Background technique

Glaucoma is global first irreversibility diseases causing blindness, and main harm is that pathologic intraocular hypertension leads to view cream Head nervous lesion and defect of visual field, if effectively treatment will lead to blindness not in time.Conventional composite trabeculectomy combines mitogen Mycin is still the treatment most common modus operandi of glaucoma.The success rate of majority glaucoma filtration operation is higher at present, but For Refractory Glaucoma, channel is effectively filtered since avascular filtering bleb related complication causes to be difficult to set up, success rate is lower.It is common Avascular filtering bleb related complication include that avascular filtering bleb scarring, postoperative Ocular hypotension, ocular hypotension ARM, avascular filtering bleb seepage are tardy Property avascular filtering bleb is scorching, adhesion etc. before and after peripheral iris tissue, choroid may occur for early stage after related data shows trabeculectomy The complication such as exudation, wound leakage, shallow of anterior chamber, hyphema, even if operation success is caused also greatly to destroy ocular knot Structure, therefore be not ideal therapeutic modality.With medical level and science and technology continuous development, operation for glaucoma gradually to Minimally invasive mode development is close, come various novel Minimally Invasive Surgeries such as emerge rapidly in large numbersBamboo shoots after a spring rain, wherein drainage device be made of gel rubber material forever The long soft miniature drainage tube of property reproduces water flow under conjunctiva by connection anterior chamber and subconjunctival space and goes out channel, promotes anterior chamber's aqueous humor Discharge achievees the effect that reduce intraocular pressure.Treatment method damage is small, and safety and validity are high.

However, the import operation of drainage tube is simultaneously inconvenient, and the propulsion of drainage tube is not when into ophthalmology surgical drainage Steadily, the precision of operation is impacted, or even patient health can be endangered.Therefore, develop a kind of structure it is simple, convenient for behaviour Make and device of the movement smoothly for the implantation of ophthalmology drainage tube has important practical significance.

Summary of the invention

The object of the invention is that solve the above-mentioned problems and to provide a kind of structure simple, design a kind of reasonable use In the device of ophthalmology drainage tube implantation.

The present invention through the following technical solutions to achieve the above objectives:

A kind of device for the implantation of ophthalmology drainage tube, including needle assembly and pushing component, the needle assembly include Needle stand and puncture needle, the needle stand top are provided with a glue groove, and the puncture needle is inserted by the top of needle stand, and crossing point glue groove is solid It is scheduled on the top of needle stand, the needle stand inside sets gradually connecting hole and communicating pipe with puncture needle contact position;

The pushing component includes the casing being flexibly connected with the needle stand end and the push rod being arranged in casing, described Sliding groove is provided in casing, the sliding groove is mutually communicated with the communicating pipe in needle stand, and the push rod is arranged in casing One end, which is provided with, pushes pin, and described push pin is mutually matched with the connecting hole size.

By using above-mentioned technical proposal, convenient for drainage tube push is entered surgical procedure region, the method is simple and quick, just In realization

As a further optimization solution of the present invention, the end of described sleeve pipe is provided with guiding cap, the table of the guiding cap Grooved hole is arranged in face, and the slot position of the guiding cap is additionally provided with guide pad, and the guide pad is led with the push rod surface It is mutually matched to slot.

By using above-mentioned technical proposal, enable push rod in the sliding groove side of casing upward sliding, and push rod makes It is more stable with sliding in the process.

As a further optimization solution of the present invention, the surface of the guiding cap is additionally provided with limiting slot, the push rod Surface is provided with the limited block with the limiting slot corresponding position.

By using above-mentioned technical proposal, so that push rod can avoid pushing away in pushing course in fixed position stop motion Pushing pin for rod end head setting is moved to the outside of puncture needle, and damages to the sufferer used.

As a further optimization solution of the present invention, sealing is additionally provided between the sliding groove inner wall and the push rod Circle.

By using above-mentioned technical proposal, resistance to sliding of the push rod in sliding groove is reduced, and avoids push rod in sliding groove Interior shaking, and then keep the movement of push rod not stable enough, to influence the progress of surgical drainage.

As a further optimization solution of the present invention, when push rod is pushed to the position that limited block and limiting slot contact with each other When, the distance between end of the end pushed pin and the puncture needle is not less than 1.5mm.

By using above-mentioned technical proposal, avoid in use making sufferer the end for releasing puncture needle of pushing pin At injury etc..

As a further optimization solution of the present invention, the diameter of the connecting hole is less than the diameter of puncture needle.

It is able to maintain puncture needle in needle stand by using above-mentioned technical proposal to limit to puncture needle Fixed position, prevents puncture needle to be moved in connecting hole, guarantees the stability of puncture needle in use.

The beneficial effects of the present invention are:

1) device of the present invention by setting for the implantation of ophthalmology drainage tube, convenient for drainage tube push is entered surgical procedure Region, the method is simple and quick, is easy to implement;

2) present invention makes push rod in the sliding groove of casing by the way that mutually matched casing and push rod are arranged in the apparatus It is mobile, certain guiding role is played to push rod;

3) present invention keeps sliding of the push rod in sliding groove more stable, enhances the essence of surgical procedure by setting sealing ring Accuracy;

4) present invention makes pushing pin for push rod end be unlikely to be exposed to the outer of puncture needle by setting limiting slot and limited block Portion, avoiding pushing pin damages surgical object;

5) the configuration of the present invention is simple, stability is high, and design rationally, is easy to implement.
