Description

A kind of dividing sewing needle for root part of iris

Technical field

This utility model is related to a kind of dividing sewing needle for root part of iris, it is adaptable to which closed type single needle continuously sutures iris root Detachment.

Background technology

Detached peripheral iris are a kind of relatively common ocular injury, are dampened by eye more and are caused.Its operation method is more, has Cut sewing, such as incarceration method, cut-out of limbus corneae sewing；With going deep into for microsurgery and Micro-traumatic concept, aforementioned operation Method is gradually eliminated, presently, it is recognized that operation method be closed type single needle continuous suture, i.e., continuous mattress suture or improvement Upper shoe suture.Conventional 1ml syringe needle (4.5 or No. 5 syringe needles), its shortcoming has suture easily to be cut off by needle point edge, so as to Cause suture to slip, cause operative failure.Chinese patent CN201727639U discloses a kind of " dividing sewing needle for root part of iris ", it Be provided with a pin hole at syringe needle head end 1mm of syringe, for stitching thread through and it is fixed, its shortcoming be needle point not Sharp keen, threading slightly has inconvenience.Chinese patent CN105342750A is disclosed a kind of " choroid, iris stitching instrument ", and sewing needle is real Heart round bar shape, its shortcoming is that needle point is not sharp keen, relatively costly, and structure slightly shows complexity, operation inconvenience.

Utility model content

Technical problem to be solved in the utility model is：A kind of simple and reasonable, threading convenience is provided, is difficult to cut off The dividing sewing needle for root part of iris of suture.

It is to solve the technical scheme that adopted of above-mentioned technical problem this utility model：A kind of detached peripheral iris suture Pin, sewing needle is syringe needle header structure, including needle point, pin stalk and pintle, and needle point has a pin hole end face, pin obstruct side wall with pin The connecting portion of hole end surface is provided with Wire channel in building, and Wire channel in building is circular arc or ellipse arc.

It is further：Angle between pin hole end face and suture needle axis is 25 °～35 °.

The beneficial effects of the utility model are：Sewing needle is syringe needle header structure, can be fixedly installed on ordinary syringe (or viscoelastic agent syringe) front end；During enforcement, surgical thread (10-0 ophthalmology nonabsorbable sutures) is penetrated by Wire channel in building, is then worn from pintle Go out, threading is convenient, and Wire channel in building is circular arc or ellipse arc, and edge is not sharp keen, does not cut off line.The letter of this utility model structure It is single reasonable, using disposable aspiration needle, can keep sharp；Own wt is lighter, easy to operate；Surgical thread is installed with needle body, is made Big operative incision need not be made of during, patient's pain is reduced, surgical work efficiency and cure rate is improved；In anterior chamber Nei Tong Cross horizontal mattress suture, using the pin can under direct-view very easily by the iris suture of Iridodialysis corneoscleral junction Gong Under film lobe, human body physiological characteristics are more met after healing；Closed type single needle can be completed in the case of wound is less and continuously sutures rainbow Film Iridodialysis, can fully meet the needs of various injury of iris sutures, rebuild iris anatomy relationship；Using cornea lateral incision, The existing cataract operation apparatus of artificial intraocular lensess' positioning hook and viscoelastic agent etc. is performed the operation, simple and convenient and easy to study, it is easy to by vast ophthalmology Doctor receives；With safely, effectively, it is practical the characteristics of；It is simple with processing technology, it is easy and safe to operate, it is easy to produce in batches The advantages of, can widely use as disposable medical article.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Labelling in figure：1- needle points, 2- pins stalk, 3- pintles, 4- Wire channel in building, 11- pin hole end faces.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail.

As shown in figure 1, sewing needle of the present utility model is syringe needle header structure, including needle point 1, pin stalk 2 and pintle 3, Needle point 1 has pin hole end face 11, and pin obstructs 2 side walls and sets being provided with Wire channel in building 4, i.e. Wire channel in building 4 with the connecting portion of pin hole end face 11 Obstruct the end of 2 sides near pin in pin hole end face 11, Wire channel in building 4 is circular arc or ellipse arc, preferably circular arc.To cause Needle point is sharp keen, and the angle between pin hole end face 11 and suture needle axis is set to 25 °～35 °, preferably 30 °.

In addition, when making, suture gauge should meet international standard 26G (or country's 4.5# syringe needles), i.e. external diameter 0.46mm, Internal diameter 0.25mm；Needle point 1, pin stalk 2 and pintle 3 should be on the same axis；Needle point 1 answers sharp mellow and full without agnail, and pin stalk 2 should be smooth (including inner surface).

In the present embodiment, syringe needle overall length is 40mm, and the length of wherein needle point+pin stalk is 20mm.

The size of Wire channel in building 1 and suture match specifications, suture is usually 10-0 ophthalmology nonabsorbable sutures, adopts in the present embodiment It is about the circular arc Wire channel in building of 0.25mm with diameter.

During operation, make conjunctival flap of the detached peripheral iris scope accordingly with fornix as substrate, expose corneoscleral junction, make phase Answer 1mm andantes layer scleral incision after scope limbus of corneae, thickness about 1/3-1/2 scleral thicknesses.In the cornea of iris detachment center offside Edge row corneal incision, injection viscoelastic agent protection eye inner tissue simultaneously separates iris detachment edge and flattening-out iris.Hand syringes Needle tubing, self-induced transparency corneal incision enters iris detachment sewing needle, at pin row to iris detachment edge end 0.5mm and through detachment rainbow Film, passes from corneosclera metaplax layer scleral incision, and clamp goes out suture, and needle retraction anterior chamber, needle point is worn up in iris detachment edge After crossing iris detachment edge, again anterior chamber is passed from corneosclera posterior scleral flaggy incision, such as detachment scope is less, then exit pin Head, knotting can repair iris detachment.As detachment scope is larger, then under band line states, for example above-mentioned method of syringe needle passes in and out anterior chamber Repeatedly, iris detachment edge is both passed through every time, until detachment root is all sutured, " W " shape cabling is formed in corneosclera and anterior chamber, The upper shoe suture of row improvement, finally tightening up stitching thread makes every needlework balancing tension, the end of a thread tail be embedded under sclera flaggy after knotting.
