Abstract

The invention belongs to the field of medical instruments, and relates to a silicone oil taking device. The silicone oil taking device mainly consists of a miniature pneumatic motor, a casing, a reciprocating pump, a needle head inner core and an external needle head; and a knob and the external needle head are arranged in the head part of the casing, a negative suction liquid outlet port is arranged in the tail part of the casing, the reciprocating pump and the miniature pneumatic motor are arranged inside the casing, one end of the reciprocating pump is connected with one end of the miniature pneumatic motor through a connecting rod, the other end of the reciprocating pump is connected with the needle head inner core, the reciprocating pump is further provided with a reciprocating pump liquid outlet port, the other end of the miniature pneumatic motor is connected with an air guide tube, and a gas inlet port is arranged on the other end of the air guide tube. According to the silicone oil taking device, a current power and negative suction device is adopted, the compatibility is good, two paths of the reciprocating pump and the negative suction can be comprehensively adjusted, and the effect is excellent; and additionally, a 3D (three-dimensional) nonlinear mode can be fully utilized for taking silicone oil out, the efficiency is high, the stability of an intraocular pressure is easily maintained, and the usability is remarkable.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to ophthalmic microsurgery equipment, in particular to a gas power, negative pressure suction, and reciprocating pump silicone oil extraction device for ophthalmic surgery; the device can be connected and fully utilized with a 3D nonlinear mode Remove the silicone oil with a vitrectomy machine. Background technique [0002] In recent years, with the continuous improvement of surgical instruments and the accumulation of experience, the indications for surgery have continued to expand. Vitrectomy (also referred to as vitrectomy) is an effective treatment for a variety of vitreoretinal diseases. With further affirmation, the application of intraocular fillers is becoming more and more important. Clinical practice shows that intraocular filling with silicone oil in the vitreous cavity can treat complex retinal detachment and complete retinal reattachment in a short time. At present, intra...
