Abstract
The utility model relates to a visual electric physiological operation monitoring electrode. An optical fiber is connected to a convex face of a cornea-touching mirror, and the other end of the optical fiber is connected with a bulb and a plug. The optical fiber is used for conducting light rays emitted from a remote light emitting source to the cornea-touching mirror; the concave face of the cornea-touching mirror is plated with a circuit of metal plated films as a metal ring; a conducting wire is connected with a single core plug to from a guide electrode. The utility model which can simultaneously stimulate eye tissues optically and record biologic electrical signal is particularly suitable for the electrophysiological monitoring on the eye tissues.
Description
This utility model relates to a kind of eye bioelectrical signals recording equipment, specifically a kind of monitor electrode for visual electrophysiotogic operation.
Bioelectrical signals by eye in ophthalmologic operation is guarded operation, the form of using abroad is to utilize visual evoked potential (VEP) at present, be a miniature bulb to be installed stimulate on the convex surface of corneal contact lens formula electroretinogram recording electrode, do not have the tinsel of the guiding signal of telecommunication on the concave surface of contact lens as luminous source.There is following problem in prior art, and the one, on the monitoring observation item of operation, can only select one, i.e. VEP, and can not two carry out synchronously.The 2nd, thorn lasing light emitter and recording electrode are installed together, increased the weight and the technical sophistication degree of electrode itself.
The purpose of this utility model is to redesign a kind ofly can observe ERG, can observe the electrode of VEP again, can finish simultaneously the optical stimulation of part tissue of eye and the record of bioelectrical signals, and will sting lasing light emitter and electrode itself is separated, to alleviate the weight of electrode itself.
The purpose of this utility model is to realize like this, in the middle of the convex surface of the corneal contact lens 8 of monitor electrode for visual electrophysiotogic operation, be connected with optical fibers 4 by fixed installation bearing 5 in the above, the other end of optical fibers 4 is connected with bulb 2 by sleeve pipe 3, bulb 2 is connected with power supply by twin-core plug 1, the becket 7 that is positioned at corneal contact lens 8 concave surfaces adopts metal coating, and has also increased a scleral contact lens 6 at the periphery of corneal contact lens 8.
This utility model has increased the thorn lasing light emitter that is connected by optical fibers on existing monitor electrode for visual electrophysiotogic operation, in operation, can observe ERG like this, can observe VEP again, and will sting lasing light emitter and electrode and itself separate, alleviated the weight of electrode itself, increased corneal contact lens 5 at epibulbar adhesive force, reduced in test process damage part tissue of eye.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is a left view of the present utility model.
Below in conjunction with accompanying drawing this utility model is done to discuss in detail: as shown in Figure 1, this utility model is mainly by corneal contact lens 8, becket 7, lead 9, single-core plug 10, bearing 5, optical fibers 4, compositions such as bulb 2 and twin-core plug 1, be coated with all metal films on the concave surface of corneal contact lens 8 and reduced the damage of corneal as becket 7, metal coating can adopt golden film or platinum plating film and save precious metal, becket 7 is connected with lead 9 by sleeve pipe 11, the other end of lead 9 is connected to single-core plug 10, increased a scleral contact lens 6 in corneal contact lens 8 neighborings, scleral contact lens 6 can be made of one with corneal contact lens 8, also can be fixedly mounted on the periphery of corneal contact lens 8, contact area with increase and eyeball, and can make between eyeball and the corneal contact lens 8 and form negative pressure, can avoid corneal contact lens 8 obscissions in use effectively, in the middle of the convex surface of corneal contact lens 8, be connected with optical fibers 4 by fixed installation bearing 5 in the above, the other end of optical fibers 4 connects by the stimulation light source bulb 2 of sleeve pipe 3, bulb 2 is connected with power supply by twin-core plug 1, bulb 2 links to each other with twin-core plug 1, can directly be plugged in the socket of grapher, alleviated the weight of electrode itself like this, made ERG and VEP can carry out record simultaneously, observe.
Of the present utility model simple in structure, reasonable in design, can finish simultaneously the optical stimulation of part tissue of eye and the record of bioelectrical signals, therefore be particularly suitable in operated eye, part tissue of eye being carried out electrophysiological monitoring.
