Abstract
The invention relates to an ophthalmostat for all-femtosecond SMILE (small incision lenticule extraction) surgery. The ophthalmostat comprises a handle, a connecting rod and a fixing ring. The handle comprises a handheld part coaxially made; one end of the handle is obliquely fixed to one side of the fixing ring through the connecting rod; a circular plane of the fixing ring is oblique to the handle; center lines of the handle, the connecting rod and the fixing ring are coplanar. The ophthalmostat can effectively immobilize an eyeball during separation of the corneal stroma lens, allowing surgeons to conveniently operate by both hands in cooperation; a certain acting point can be given to the hand separating the lens, along the radial line of the eyeball; the separation is made smoother and more effective; handle is clearer; success rate of complete extraction of the corneal stroma lens can be increased, and surgical complications such as lens residue and fracture are decreased.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to the micro-surgical instruments relevant with cornea refractive surgery, especially a kind of ophthalmostat of performing the operation for full femtosecond SMILE.
Background technology
In recent years, along with the application of femtosecond laser, cornea refractive surgery enters a brand-new developmental stage.Femtosecond laser cuts accurately with it, good safety and predictability, and cornea refractive surgery is introduced new epoch.And in recent years, the important breakthrough of operation designing theory has been achieved in the appearance of femtosecond laser minimal incision * substrate lens removal surgery (small incision lenticule extraction, SMILE) especially.This operation is without the making of cornea flap, avoid a series of because making the postoperative complication that cornea flap causes, it also avoid corneal flap displacement that Post operation causes because of wound etc. and the postoperative potential safety hazard such as biomechanical stability is influenced simultaneously, the use of femtosecond laser, make the accuracy of performing the operation, safety and predictability are all significantly improved than before.The feature of full femtosecond SMILE operation " minimal incision * " and " without valve " is significant innovation again of cornea refractive surgery theory and technology, its operation principle is the corneal stroma plane preset by femtosecond laser vernier focusing, carry out the rear surface of substrate lens and the scanning of front surface successively, then be that the limit of lens is cut and cut with the limit of cornea flap, next step is then utilize micro-separation instrument to be thoroughly separated by lense tissue and take out from otch, completes operation.The appearance that full femtosecond SMILE performs the operation has epoch-making meaning, also indicates the arrival in Wicresoft's epoch of cornea refractive surgery simultaneously.
Full femtosecond SMILE, as a kind of new cornea refractive surgery technology, requires relatively high to operation operation skill, and while needing abundant surgical experience, the reasonable employment of operating theater instruments is also the key point improving success rate of operation.In full femtosecond SMILE operation process, the separation of corneal stroma lens and taking-up are extremely crucial steps, are directly connected to the success or failure of operation.Hands art in the past, when being separated and take out corneal stroma lens, surgical doctor carries out the fixing of eyeball often through the apparatus such as cotton swab or tweezers, because eyeball is a spheroid, and smooth surface, be fixed up and acquire a certain degree of difficulty, make doctor in the process of dialyte lens, due to the slip of eyeball, effective eyeball cannot be carried out fix and affect operation, thus it is incomplete that lens separation occurs, take out difficulty, the complication such as lens fracture or tissue residue, simultaneously, the clamping of tweezers also may cause conjunctiva to be torn, the iatrogenic injuries such as hemorrhage even scuffing, severe patient may affect the carrying out of operation and the recovery of postoperative patient vision, therefore, need a kind of new ophthalmostat tool at present badly to meet user demand.
A good operating theater instruments, effectively assisting operation doctor can not only carry out operation technique, make operation carry out more smooth and easy, also can reduce complication in art and postoperative simultaneously.
Full femtosecond SMILE performs the operation as a kind of emerging surgical technic, up to now still without relevant ophthalmostat tool.
By retrieval, not yet find the patent document relevant to patent application of the present invention.
Summary of the invention
The object of the invention is the blank filling up existing operation technique apparatus used, there is provided that a kind of structure is simple, the ophthalmostat made in full femtosecond SMILE operation process easy, easy to use, this ophthalmostat can be used in carrying out carrying out definitely and effectively fixing to eyeball in the separation process of corneal stroma lens, facilitate the operation of patient, improve the success rate of the complete taking-up of lens, decrease the postoperative complications such as lens are residual, broken.
The object of the invention is to be achieved through the following technical solutions:
A kind of ophthalmostat of performing the operation for full femtosecond SMILE, described ophthalmostat comprises handle, connecting rod and retainer ring, described handle comprises coaxial system handgrip part thereon, one end of described handle is solidly installed by a side of connecting rod and retainer ring, and the centrage of this handle, connecting rod and retainer ring in one plane;
Described retainer ring is the circular of opening, and described connecting rod is connected on a nearly opening of retainer ring, and the curved design of ring inner surface from top to bottom in the gradient of this retainer ring, radian and the anterior corneal surface curvature of its curved surface match.
And plane of a loop and the handle of described retainer ring are inclined to set.
And the plane of a loop of described retainer ring and the angle of inclination of handle are 45 degree.
And the outer surface of described handgrip part is shaped with anti-slip veins.
And the material of described handle, connecting rod and retainer ring is medical stainless steel.
Advantage of the present invention and good effect are:
1, this holder effectively keeps eyeball to fix when isolated cornea substrate lens, facilitate the operation of patient, both hands compounding practice can also give lens lock out operation hands with certain impetus in the radial line direction of eyeball, substrate lens are separated more smooth and easy, more effective, feel is more definite, the success rate of the complete taking-up of corneal stroma lens in art can be improved, the postoperative complications such as minimizing lens are residual, broken.
2, the ring inner surface of the retainer ring of this holder is from top to bottom in the curved design of the gradient, and radian and the anterior corneal surface curvature of its curved surface match, and the ring inner surface of this retainer ring and eyeball surface are closely attached, and increases its fixation to eyeball.
3, the retainer ring of this holder is opening-like, and make in art while eyeball is fixing by this ophthalmostat, operating theater instruments can freely be come in and gone out, and does not affect the taking-up of substrate lens, is convenient to operation.
4, the plane of a loop of the retainer ring of this holder and handle are inclined to set, and this structure be obliquely installed is beneficial to the operation of operation; The outer surface of handgrip part is shaped with anti-slip veins, prevents the generation of slippage in operation process, makes operation technique safer, smooth.
