Abstract
The utility model belongs to the medical instrument field, in particular relating to an eyeball fixer for surgical operation. The eyeball fixer includes a negative pressure sucking opening which is placed on a handle and connected with a negative pressure sucking pipe and a negative pressure generator. During the use, the whole cornea is placed in a ring, which is convenient for the cornea optical central positioning for the operated; the negative pressure exerts a roll on the sclera, which has little influence on the cornea, and the pressure on the eyeball after the sucking can be adjusted to the physiological value according to the need, without any structural or functional impairment brought to the eye. The eyeball fixer ensures that the optical center is not to be displaced or flowed away during the operation and compensates the defects of the traditional molecular laser instruments.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of surgical operation ophthalmostat.
Background technology
The excimer laser treatment ametropia (comprises myopia, hypermetropia and astigmatism), LASIK (laserin situ keratomileusis, laser in situ keratomileusis) and PRK (photorefractivekeratectomy PRK (phototherapeutic keratectomy)) are increasingly mature.There are every year hundreds thousand of myopia patients to accept this operation.The exploitation of the equipment relevant with refractive surgery, apparatus, software etc. is also constantly released.Because when operation, eyeball can take place independently not rotate, how to guarantee in the art that optical center is not offset or waves is the key of avoiding the cutting of refractive surgery partial center, be the problem that the refractive surgery doctor is concerned about very much.Labelling pupil central authorities and pupil edges such as Gobiie are followed the tracks of pupil center's design tracking system by infrared ray, reduced partially in emerging phenomenon.China began to introduce the excimer laser instrument of being furnished with tracking system in 2000.But present domestic most quasi-molecules all are not furnished with eye position tracking system.
Eye position tracking system is a much progress of excimer laser instrument, also is that starting point such as the excimer laser instrument that quasi-molecule office instrument further develops united corneal topography, wave front aberration.But also have weak point: 1 the cost an arm and a leg excimer laser instrument price of eye position tracking system is higher more than 1,000,000 than traditional excimer laser instrument.2 can't dispose eye position tracking system on traditional excimer laser instrument basis.3 position tracking systems are mismatched as patient's utmost point following the tracks of under some situation, corneal stroma edema in the art, and chip covers lesser ring of Merkel, microcoria, nystagmus patient.4 can not eliminate the caused optical axis of eyeball position deflection and laser direction inconsistent.
Summary of the invention
The purpose of this utility model provides a kind of surgery ophthalmostat.It is that traditional excimer laser instrument disposes upward " eye position tracking system " that this utility model can make the most excimer laser instrument of China, guarantees that optical center does not take place to be offset or to wave in the art, can fundamentally remedy the defective of traditional excimer laser instrument.
This utility model ophthalmostat is by attracting ring 1 to make by the vacuum suction pipe connection depression generator that is connected on the vacuum aspiration port 2.One end of this ophthalmostat is made the attraction ring of tubular type hollow, the one side of its contact eyeball is provided with the slit and is incomplete closed, the ring body height is the 2.5-3 millimeter, internal ring 3 diameters are 11～12mm, and outer shroud 4 diameters are 18～21mm, the fixedly connected hollow handle 5 of ring body one side, the long 10-15 of handle centimetre, angle is the 120-150 degree between ring body and the handle, and vacuum aspiration port is established on the handle top, can connect depression generator by the vacuum suction pipe.The depression generator that this utility model adopts can be a modified model KN-5000 lamellar cornea formation system control chamber.
When this ophthalmostat used, whole cornea was positioned at ring, is convenient to the centralized positioning of operator optics of cornea, and suction function is on sclera, and the influence of corneal form is little.Simultaneously, can adjust attraction back eyeball pressure as required is biological value 15～22mmHg, can not cause eye structure damage and dysfunction this moment.
This ophthalmostat has been compared following advantage with infrared eye position tracking system:
1 can combine with traditional excimer laser instrument, has remedied the defective of traditional excimer laser instrument
2 is cheap, only must 50,000 RMB
3 couples of very ill-matched patients are also effective
4 can to eliminate eye biased tiltedly
5 also are applicable to nystagmus and pupil smaller.
Description of drawings
Fig. 1 is this ophthalmostat structural representation
Wherein 1 is to attract ring, the 2nd, and vacuum aspiration port, the 3rd, internal ring, the 4th, outer shroud,
The 5th, handle.
The specific embodiment
Embodiment 1
But adopt medical metal material, make the attraction ring of hollow, the ring body height is 3 millimeters, interior ring diameter is 11, outer ring diameter is 18, the fixedly connected 15 centimetres of hollow handles of ring body one side, and angle is 130 degree between ring body and the handle, vacuum aspiration port is established on the handle top, connects negative pressure generator by the vacuum suction pipe.During the row excimer laser surgery, look bad the ring that can attract admittedly as the patient and oppress in the limbus of corneae position, the startup negative pressure generator holds eyeball, and eyeball is placed the operation desired location.Admittedly look bad patient through the hundreds of examples of clinic trial, the postoperative partial center all keeps in the 0.3mm, is better than eye position tracking system.
Claims (4)
1, a kind of operation ophthalmostat is characterized in that by attracting ring to connect vacuum suction pipe and depression generator by the vacuum aspiration port that is located on the handle.
2, operation ophthalmostat according to claim 1 is characterized in that an end of described ophthalmostat is made tubular type hollow attraction ring, and one side of its contact eyeball is provided with the slit and is incomplete closed, and ring body one side connects hollow handle.
3, according to claim 1 and 2 described operation ophthalmostats, it is characterized in that described ophthalmostat ring body height is the 2.5-3 millimeter, interior ring diameter is 11～12mm, outer ring diameter is 18～21mm.
4, according to claim 1 and 2 described operation ophthalmostats, it is characterized in that long 10-15 centimetre of described ophthalmostat handle, angle is the 120-150 degree between ring body and the handle.
