Abstract
The utility model discloses a noninvasive negative-pressure fixator in ophthalmology, comprising a segment-shaped sucking tip, an air pipe and an air bag, wherein the sucking tip is arranged at the lower end of the air pipe and mutually communicated and hermetically connected with the air pipe, the air bag is arranged at the upper end of the air pipe and mutually communicated and hermetically connected with the air pipe, the middle upper part of the outer wall of the air pipe is provided with a handle; and the outer wall of the air pipe is provided with a scale layer along the length direction of the air pipe. The eyeball fixer utilizes the principle of negative-pressure attraction, not only has good effects, no pain and no injury, but also is simple, convenient and fast to use.
Description
Technical field
This utility model relates to eyeball fixture in a kind of ophthalmologic operation, particularly a kind of non-invasive negative-pressure fixer in ophthalmology.
Background technology
Traditional operated eye fixed apparatus is that the former has damaging action to part tissue of eye with toothed forceps and Smooth forceps, and the latter is because fixing part tissue of eye is generally used for the knotting of suture.Develop rapidly along with Ophthalimic microsurgery, the ultrasonic emulsification operation reaches its maturity, the implantation of transparency cornea otch and foldable intraocular lens, whole surgery is carried out on the avascular area cornea of eye, so perfectly operation is that eye does not have the petechia, but do the keratonyxis hole in the art and when tearing capsule, owing to be topical anesthesia, best fixing eyeball for the sake of security.At present the doctor still uses toothed forceps when carrying out ophthalmologic operation, but toothed forceps damages the conjunctiva blood vessel easily, causes hemorrhagely, both part tissue of eye is caused damage, increase sensation of pricking, may leave a trace in injury region after surgery again, and it is attractive in appearance to influence eye.Resemble common cataractous ECCE, pterygium enucleation, cornea deep layer foreign body taking-up operation etc., all have the problems referred to above.
The utility model content
The purpose of this utility model just is to provide a kind of gravitational principle of negative pressure of utilizing, not only effective, no pain, not damaged, and use simply, non-invasive negative-pressure fixer in ophthalmology easily and efficiently.
To achieve these goals, the technical solution adopted in the utility model is such: non-invasive negative-pressure fixer in ophthalmology of the present utility model, the suction nozzle, trachea and the air bag that comprise the segment shape, suction nozzle is arranged on the trachea lower end and is tightly connected with the trachea intercommunication, air bag is arranged on the trachea upper end and is tightly connected with the trachea intercommunication, be provided with one handle in trachea outer wall middle and upper part, the trachea length direction is provided with the scale layer in trachea outer wall upper edge.
As preferably, described trachea length is 10-15cm.
As preferably, described handle is near air bag.
As preferably, described air bag, trachea and suction nozzle all adopt the once moulding manufacturing of silicon gel, hydrogel, acrylate or polymethyl methacrylate.
Compared with prior art, advantage of the present utility model is: when carrying out ophthalmologic operation, use fixedly eyeball of this holder, and convenient, fast, reliable, and there are not pain, not damaged, postoperative is trace not, and it is attractive in appearance not influence eye, if there is vein blood vessel on the part tissue of eye surface of being adsorbed by suction nozzle, this holder also has auxiliary hemostatic function, can replace the toothed forceps in the ophthalmologic operation, allow the more pleased acceptance of patient, and help ophthalmologic operation safety, carry out quickly and smoothly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, non-invasive negative-pressure fixer in ophthalmology of the present utility model, the suction nozzle 1 that comprises the segment shape, trachea 2 and air bag 3, suction nozzle 1 is arranged on trachea 2 lower ends and is tightly connected with trachea 2 intercommunications, air bag 3 is arranged on trachea 2 upper ends and is tightly connected with trachea 2 intercommunications, be provided with one handle 4 in trachea 2 outer wall middle and upper parts, be provided with scale layer 5 at trachea 2 outer wall upper edge trachea 2 length directions, described trachea 2 length are 10-15cm, described handle 4 is near air bag 3, described air bag 3, trachea 2 and suction nozzle 1 all adopt the silicon gel, hydrogel, the once moulding manufacturing of acrylate or polymethyl methacrylate.
During use, pinch air bag 3 with thumb and forefinger, middle finger passes handle 4 and holds trachea 2, the convenient holder of firmly holding, avoid causing danger because of the hands shake, suction nozzle 1 is adsorbed on the cornea of eyeball and can undergos surgery smoothly, on trachea 2, be provided with scale layer 5, be beneficial to the tram of finding operation accurately.
Claims (4)
