In pipe insertion needle tubing, provided with positioning plug between the needle tubing and sleeve pipe, the needle tubing tube chamber front end is provided with position-limiting tube, the needle tubing
Front end connecting needle, the needle-covering cap is arranged on needle tip.
The syringe needle is arc syringe needle.
The syringe needle is made up of metal or high polymer material.
It is provided with optical fiber in the fibre-optic catheter, the extension of optical fiber of fibre-optic catheter front end to needle tip.
The optical fiber front end is antisitic defect round end structure.
Comprise the following steps：
A. by trochar from scleral flap tripping in pin, the passage of scintillation light sent according to luminous trochar front end optical fiber indicates that lime is applied on edge
Family name's pipe direction of travel is in sqclerotal interlayer traveling；
B. trochar syringe needle is passed at surgical incision, forward pushing sleeve pipe so that the optical fiber in syringe needle is pushed out syringe needle, positioning
Plug and optical fiber are also moved forward therewith, until positioning plug be moved at position-limiting tube, it is impossible to forward, optical fiber also will not continue to by
Release, so far optical fiber front end has been pushed out syringe needle, and the round end structure of optical fiber front end is exposed, the distance that optical fiber is released is positioning glue
Fill in mobile distance.
C. suture is tied up in the round end structure of optical fiber, Lai Mushi pipes direction of travel rollback is applied on edge after the two linking is stable
Trochar, suture is taken out of.
Beneficial effects of the present invention：A kind of luminous trochar of ophthalmology and its application method, the optical fiber hair of the trochar are provided
Light technology can in surgical procedure real-time indication trocar position, provided a great convenience to doctor, reduce operation
Risk；The arc of the trochar syringe needle is set, and is conducive to the physiological curve inserting needle of syringe needle laminating tissue, it is to avoid to the wound of tissue
Evil；The round end structure of the optical fiber front end of the trochar not only antisitic defect, and prevent the suture for lying in optical fiber from coming off.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the luminous trochar of ophthalmology of the present invention.
Label declaration in figure：1- fibre-optic catheters, 2-SC joints, 3- sleeve pipes, 4- positioning plugs, 5- position-limiting tubes, 6- needle tubings, 7-
Syringe needle, 8- needle-covering caps, 9- optical fiber, 10- round ends, 11- sutures.
Embodiment
Embodiment:
The trochar as shown in figure 1, ophthalmology of the present invention lights, including SC joints 2, fibre-optic catheter 1, sleeve pipe 3, needle tubing 6, syringe needle 7,
Position plug 4, position-limiting tube 5, needle-covering cap 8.
The rear end of the fibre-optic catheter 1 connection SC joints 2, SC joints 2 are connected with equipment.Set is fixed in the front end of fibre-optic catheter 1
In pipe 3, in the insertion needle tubing 6 of sleeve pipe 3.Provided with positioning plug 4 between needle tubing 6 and sleeve pipe 3, the free skating in needle tubing 6 of sleeve pipe 3 is prevented
It is dynamic.Be provided with optical fiber 9 in fibre-optic catheter 1, optical fiber luminescent technology can in surgical procedure real-time indication trocar position, to doctor
Life is provided a great convenience, and reduces operation risk.The optical fiber 9 of the front end of fibre-optic catheter 1 extends to the front end of syringe needle 7.Before optical fiber 9
Hold as the structure of round end 10, not only antisitic defect, and prevent the suture 11 for lying in optical fiber from coming off.The front end connecting needle 7 of needle tubing 6, pin
First 7 are set to arc, are conducive to the physiological curve inserting needle of the laminating tissue of syringe needle 7, it is to avoid the injury to tissue.The tube chamber front end of needle tubing 6
Provided with position-limiting tube 5, prevent optical fiber 9 from excessively being released at syringe needle 7.Needle-covering cap 8 is used to protect syringe needle 7 in transportation,
During operation, needle-covering cap 8 will be removed.
The surgical procedure that trochar is used for is：Temporo side at the past trabecular resection position, does the conjunctiva using arched roof as substrate
Valve, makes two layers of scleral flap of the depth, Lai Mushi pipes are applied in exposure, and along away from former surgical scars position direction, microtubular is inserted
To traveling in Lai Mushi pipes is applied Lai Mushi pipe incision positions are applied to farthest, i.e. the past surgical injury.Radial incision here
Sclera takes out after microtubular, ligation suture to Lai Mushi pipes are applied, withdraws microtubular, viscoelastic agent is injected when withdrawing.(A) will hair
The scleral flap tripping in pin that light trochar makes from this operation, the passage of scintillation light instruction sent according to luminous trochar front end optical fiber,
Lai Mushi pipes direction of travel is applied in sqclerotal interlayer traveling in edge.(B) trochar syringe needle is passed at surgical incision, forward pushing sleeve
Pipe so that the optical fiber in syringe needle is pushed out syringe needle, positioning plug and optical fiber are also moved forward therewith, until positioning plug is moved to
At position-limiting tube, it is impossible to forward, optical fiber also will not continue to be pushed out, and so far optical fiber front end has been pushed out syringe needle, the circle of optical fiber front end
Header structure exposes, and positioning plug and position-limiting tube ensure that optical fiber will not be released excessively, so as to ensure that the stabilization of optical fiber front end
Property, it is to avoid optical fiber is broken off.The distance that optical fiber is released is the distance for positioning plug movement.(C) suture is tied up into optical fiber
In round end structure, along Lai Mushi pipe direction of travel rollback trochars are applied after the two linking is stable, suture is taken out of.Tension ligation
Suture, Close suture scleral flap and conjunctival flap.
The preferred embodiment of the embodiment of the present invention is these are only, embodiment is not intended to limit the invention, it is all at this
Within the spirit and principle of inventive embodiments, any modification, equivalent substitution and improvements made etc. should be included in of the invention real
