Abstract

The invention discloses a silicone oil extracting device for an ophthalmology department. The silicone oil extracting device comprises a negative pressure assembly for generating negative pressure and a extracting assembly for extracting silicone oil; the negative pressure assembly comprise a barrel body with a containing cavity and a piston and a piston rod which are arranged in the containing cavity; the extracting assembly comprises a catheter which is communicated with the containing cavity; the rod wall of the piston rod is connected with a push-pull part, a sliding groove is formed in the barrel wall of the barrel body, the push-pull part penetrates out from the sliding groove, and the push-pull part drives the piston rod to move in the axial direction of the containing cavity when the push-pull part slides in the length direction of the sliding groove; a limit groove which is communicated with the sliding groove and used for limiting movement of the push-pull part is formed in the barrel wall of the barrel body. According to the silicone oil extracting device for the ophthalmology department, the piston rod can be positioned reliably and effectively to prevent an operation from being failed, the pain of a patient is relieved, the structure is simple, and the operation can be conveniently operated.

Description

technical field

[0001] The invention relates to an ophthalmic medical device, in particular to an ophthalmic silicone oil removal device. Background technique

[0002] Vitrectomy combined with silicone oil intraocular filling for retinal detachment has become a routine clinical operation method. Silicone oil is filled into the patient's eye to support the retinal reset. After the patient's retina is completely reset, the silicone oil in the patient's eye is removed. At present, the medical consumables commonly used in intraocular silicone oil extraction are the silicone oil extraction kits produced by vitrectomy machine manufacturers, which use the continuous negative pressure generated by the vitrectomy machine to remove intraocular silicone oil through the relevant equipment provided by the oil extraction kit. . The price of this medical device is very expensive. In clinical application, the entire operation fee is high, which leads to the high cost of the entire treatmen...
