Abstract
The invention discloses a minimally invasive quantitative controllable design for fetching silicone oil from eyes, provides a method for fetching silicone oil from eyes in a minimally invasive, quantitative and controllable manner, and relates to improvement of methods for medical operation. The method has the advantages that the method mainly aims to accurately control negative pressures in real time when the silicone oil is fetched on the premise that special equipment is omitted, the negative pressures can be quickly released when liquid of vitreous cavities is mistakenly sucked, and accordingly severe problems of mistaken suction of ocular tissues, collapse of eyeballs and the like can be solved; double negative pressure release links of a manual valve are regulated and controlled by a conventional negative-pressure sucker and the manual valve of a negative-pressure tube when continuous quantitative negative-pressure suction assistance is required, so that the method mainly can be implemented, and tissue injury can be reduced by the aid of 23G minimally invasive incision; the 23G puncture incision is adopted in the method, the head of a 1 ml syringe is connected with a 22G intravenous indwelling canula to enter the eyes to suck the silicone oil, a disposable sputum sucking tube is connected with the tail of the syringe, the tail of the sputum sucking tube is further connected with a disposable suction connecting tube and then is connected with the conventional wall type or vertical negative-pressure sucker, negative-pressure values are set by the negative-pressure sucker, and operators can flexibly adjust the negative pressures by means of mastering an opening degree of the manual valve; all service materials are common articles for operation rooms, and accordingly the method is convenient to popularize.
Description
Technical field
The present invention is that the Wicresoft that a kind of intra-ocular silicon oil takes out quantizes controlled design, relates to the improvement of medical care precess method.
Background technology
Automatically released by top sclera or corneal incision under current intra-ocular silicon oil mode of taking out is generally intraocular irrigation, syringe allows manual aspiration or phaco suction are taken out greatly.Automatic emitting rate remains slowly, easily, and flows out silicone oil and fill the air and affect surgical field of view; During allows manual aspiration, vacuum cavitations and operation technique generally adhere to two people separately, to waste time and energy and negative pressure cannot accurately control in real time, when silicone oil amount is few, dust collecter may suck vitreous humor by mistake, now can not remove negative pressure immediately and easily cause the severe complication such as atrophy of eyeball, Wu Xi eye inner tissue; Phaco gets oil then must by special installation, and cost is high and same exist when inhaling can not the shortcoming such as Rapid reversal negative pressure by mistake.Main purpose of the present invention accurately controls negative pressure when not realizing silicone oil removal by special installation in real time, and guarantee that handling safety gets speed oil simultaneously also very fast, the operation visual field is totally clear, and mini-incision is little to ocular tissue's damage.Vacuum cavitations is mainly through the manual valve of conventional vacuum extractor and negative tube, discharge two dual regulation and control of link with the auxiliary manual valve negative pressure if desired of lasting quantification vacuum suction to realize, operational approach handy and safe, all use materials are operating room ordinary articles, are convenient to promote.
Summary of the invention
This method invention adopts eyeball pars plana 23G Wicresoft's perfusion and gets oily otch, the 1ml syringe head end removing nook closing member and syringe needle is connected disposable vein indwelling casing tube (22G, reserved about 1cm is long for sleeve pipe head end, top is cut into 45 degree of inclined-planes) get oily otch from top and enter ophthalmic, syringe afterbody connects disposal sputum collecting cannula, and (F16 is with valve, wipe out head end side opening) and disposable suction connecting tube (F28), suction connecting tube afterbody connects wall type or vertical conventional vacuum extractor, vacuum extractor can arrange vacuum suction numerical value, valve can be grasped degree of opening by operator doctor and come to adjust negative pressure flexibly further, when missing the emergencies such as suction, operator doctor can make negative pressure decline fast by completely open valve immediately, avoid atrophy of eyeball and eye inner tissue's damage, 1ml syringe can also rough estimate silicone oil removal amount except facilitating operation by human hand simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this method invention is described further
Fig. 1 is equipment therefor structural representation of the present invention
Shown in figure: 1,23G puncture incision (wherein get oily otch and remove puncture casing) 2, disposable vein indwelling casing tube (the reserved about 1cm length of 22G, sleeve pipe head end, top are cut into about 45 degree of inclined-planes) 3,1ml syringe (removing nook closing member and syringe needle) 4, disposal sputum collecting cannula (F16 wipes out head end side opening) 5, disposable suction connecting tube (F28) 6, manual valve 7, vacuum extractor
Detailed description of the invention
According to Fig. 1, the specific embodiment of the invention is described further below: connect disposable vein indwelling casing tube (2), 1ml syringe (3), disposal sputum collecting cannula (4), disposable suction connecting tube (5) by Fig. 1, and it is for subsequent use suction connecting tube to be accessed conventional vacuum extractor (7).After performing intraocular irrigation and suction slit (1), venous indwelling sleeve pipe is inserted in intra-ocular silicon oil bubble, close manual valve (6), open vacuum extractor and initial negative pressure value (first can preset 400mmHg) is set, according to adjusting negative pressure value according to silicone oil sucking-off speed in art, when silicone oil is less, open manual valve (6) uses thumb shutoff instead, negative pressure is adjusted further by grasping valve shutoff degree, thus reach the object of two ore control suction, realize accurately controlling in real time suction.1ml syringe can also be used for rough estimate silicone oil removal amount (about 0.3 ml/min) except facilitating operation by human hand.
Claims (1)
1. Wicresoft quantizes controlled intra-ocular silicon oil removing method, comprise combinationally using of 23G mini-incision, disposable vein indwelling casing tube, 1ml syringe, disposal sputum collecting cannula, disposable suction connecting tube and wall type or vertical conventional vacuum extractor, feature is mini-incision and continues to quantize vacuum suction and assist manual valve negative pressure if desired to discharge two links to the two ore control of suction.
