Method for fetching silicone oil from eyes in minimally invasive, quantitative and controllable manner

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 [0001] The invention relates to a minimally invasive and quantitatively controllable design for taking out intraocular silicone oil, and relates to the improvement of medical operation methods. Background technique [0002] At present, the removal methods of intraocular silicone oil are generally automatic release through the upper sclera or corneal incision under intraocular perfusion, manual suction with a large syringe or suction with a vitrectomy machine, etc. The speed of automatic release is slow, it is easy to remain, and the outflow of silicone oil diffuses and affects the surgical field of vision; the negative pressure control and surgical operation are generally divided into two people during manual suction, which is time-consuming and laborious, and the negative pressure cannot be accurately controlled in real time. When the amount of silicone oil is small, the suction head Vitreous humor may be inhaled by mistake. If the negative pressure is not r...

Problems solved by technology

The speed of automatic release is slow, it is easy to remain, and the outflow of silicone oil diffuses and affects the surgical field of vision; the negative pressure control and surgical operation are generally divided into two people during manual suction, which is time-consuming and laborious, and the negative pressure cannot be accurately controlled in real time. When the amount of silicone oil is small, the suction head Vitreous humor may be inhaled by mistake. If the negative pressure is not released immediately, it may cause serious complications such as eyeball collapse and aspiration of intraocular tissue; the vitrectomy machine must use special equipment to extract oil, which is costly and cannot be quickly relieved when aspiration is also present. Disadvantages such as negative pressure
