Abstract
The utility model relates to an anterior chamber maintainer, which comprises an inserting tube (1), a connecting hose (2) and an infusion instrument joint (3). The front end of the inserting tube (1) adopts a semispherical shape, and at least two infusion holes (4) are uniformly formed on the tube wall near the front end, and uniformly communicated with passages (5) at the inner part of the inserting tube (1); the back end of the inserting tube (1) is inserted in the connecting hose (2); and the connecting hose (2) is connected with the infusion instrument joint (3). The inserting tube (1) is made of medical metal materials and the outer surface of the inserting tube is processed with tiny sands. The utility model has the advantages that the structure is simple, fixed and reliable; the impulsive force of water flow is small; the water leakage can be prevented; the use operation is simple; and can be widely used as a one-off medical article.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to anterior chamber's retainer that a kind of ophthalmologic operation is used.
Background technology
Aqueous humor is water white liquid, has nutrition and keeps the effect of intraocular pressure.Aqueous humor is constantly produced by corpus ciliare, enters blood through back room-pupil-angle of anterior chamber-discharge.Aqueous humor is different from tear, and tear are to be produced outward by eye.The internal pressure (intraocular pressure) of eye depends on the amount of aqueous humor.Aqueous humor is produced by corpus ciliare and enters the anterior chamber by pupil then, discharges eyeball by the trabecular reticulum of angle of anterior chamber again.The aqueous humor system works of eyes is talked about normally, and the aqueous humor growing amount should just in time equal the output of aqueous humor.
When ophthalmologic operation, for carrying out smoothly of keeping performing the operation, the anterior chamber keeps particular importance in the space in the time of must carrying out keeping of anterior chamber's pressure, particularly ECCE, phacoemulsification, intraocular lens implants, anterior chamber's flush operation, glaucoma filtration surgery, vitrectomy associating cataract operation, silicone oil removal surgery.The main purpose that the anterior chamber keeps is: (1) operation overall process keeps the ophthalmic malleation, and has bigger tolerance fluid loss to cause the deposit that intraocular pressure changes; (2) keep the enough degree of depth of anterior chamber, satisfied working place is provided; (3) spill infusion liquid by otch, can get rid of blood, pigment and inflammatory factor that operation produces; (4) anterior chamber's malleation makes the back cyst membrane to afterwale, reduces cyst membrane disruptive chance in back in the art; (5) can use injection pressure floats the nucleus lentis dislocation; (6) tearing capsule need not can finish by viscoelastic agent.
Use anterior chamber's retainer, can form good and stable anterior chamber automatically, reduce the use of viscoelastic agent, reduce surgery cost.The anterior chamber's retainer that uses clinically is a simple metal hollow pipe at present, and the top is the oval perfusing hole in an inclined-plane, and end connects silica gel tube, tube for transfusion, perfusion bottle.This anterior chamber's retainer is the single hole reperfusion structure, and current are too concentrated, and impulse force is bigger, can cause certain problem, current directly impact the vulnerable area and the endothelial cell of lens capsule bag, cause easily that posterior lens capsule breaks and endothelial cell damage, have brought certain inconvenience to operation technique.Key is that this anterior chamber's retainer top is most advanced and sophisticated, very sharp keen, may cause the damage of eye inner tissue.In addition, this anterior chamber's retainer ophthalmic part is more smooth, comes off easily and causes and leak, and surgical effect is affected.
In view of above reason, anterior chamber's retainer haves much room for improvement at present, press for a kind of fixing reliable, impulsive force is less, can prevent to leak, anterior chamber's retainer simple to operate.
The utility model content
This utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of fixing reliable, impulsive force is less, can prevent to leak, ophthalmologic operation simple to operate anterior chamber's retainer.
The purpose of this utility model is realized by following technical scheme:
A kind of ophthalmologic operation anterior chamber's retainer is made up of intubate, connection sebific duct and transfusion device joint three parts; The front end of described intubate is hemispherical, avoided damage to eye inner tissue, evenly have at least two infusion holes near on the tube wall of front end, these infusion holes all with the channel connection of intubate inside, will be divided into a plurality of current from the infusion liquid of perfusion bottle, be formed uniformly and keep anterior chamber's pressure, a little less than the single impulsive force, little to eye inner tissue's impulse force, damage for a short time, cornea is safer.Connect the sebific duct internal diameter and be slightly less than cannula outer diameter, for the elasticity medical material is made, can place cannula outer diameter one end with comparalive ease, and drainage can not take place.Connect the sebific duct other end and link to each other, liquid can be transported to the anterior chamber by transfusion device joint, connection sebific duct, intubate by the transfusion device joint with the transfusion device joint.
Described intubate is that medical metal material is made, and outer surface is that trickle frosted is handled, and can prevent the appearance of obscission.
This utility model is simple in structure, and is fixing reliable, and impulsive force is less, can prevent to leak, and uses simple to operately, and it is widely-used to can be used as disposable medical article.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
Referring to Fig. 1, this utility model is made up of intubate 1, connection sebific duct 2 and transfusion device joint 3 three parts.The front end of intubate 1 is hemispherical, evenly have plural circle or oval infusion hole 4 in intubate 1 near on the tube wall of front position, these infusion holes 4 all are connected with the passage 5 of intubate 1 inside, intubate 1 is made for medical metal material, outer surface is that trickle frosted is handled, and can prevent the appearance of obscission.Connect sebific duct 2 internal diameters and be slightly less than intubate 1 external diameter,, intubate 1 is inserted, connect sebific duct 2 other ends and link to each other with transfusion device joint 3 for the elasticity medical material is made.
After carrying out preceding preparation of art and anesthesia during concrete the use earlier, strut palpebra inferior with eye speculum, outer bulbar conjunctiva of fixation forceps clamping point of puncture offside or homonymy limbus of corneae and fascia be eyeball fixedly, 0.5～1mm does the horizontal cut that half penetrates with the paracentesis of anterior chamber cutter in the limbus of corneae of temporo top, anterior chamber's retainer intubate 1 is inserted in the otch gently, and the otch size is complementary with intubate 1 external diameter, therefore, need not sutured, intubate 1 can closely contact with otch.Connect the perfusion pipeline, perfusion bottle is got final product apart from about the about 50cm in eyeball plane.
The dabbling beginning of flow regulator may command by adjusting infusion bottle height and tube for transfusion, close and anterior chamber's pressure size.
