Intraocular foreign matter suction device

Abstract

The invention provides an intraocular foreign matter suction device, wherein the non-magnetic foreign matter taking-out effect can be effectively improved, and the problem that when existing intraocular non-magnetic foreign matter is grabbed, grabbing is not firm, and secondary damage to intraocular tissue is caused is solved. The intraocular foreign matter suction device comprises a handle, forceps claws, a movable suction pipe, a push button, a suction source and a suction cup. The handle is of a sleeve structure, the movable suction pipe is arranged in the handle, an internal thread is arranged in a center hole in the front end of the movable suction pipe, an external thread is arranged on the outer wall of the front end of the movable suction pipe, the rear end of the movable suction pipe is connected with a suction source arranged outside the handle, and the suction source is used for providing negative pressure for sucking foreign matter. The push button is arranged on the handle and is connected with the movable suction pipe; the suction cup is connected with an internal thread at the front end of the movable suction pipe, and meanwhile a plurality of suction holes communicated with an inner cavity of the movable suction pipe are formed in the suction cup. The forceps claws are connected with external threads at the front end of the movable suction pipe.

Description

technical field [0001] The invention relates to the field of ophthalmic medical instruments, in particular to an intraocular foreign body suction device. Background technique [0002] In clinical practice, intraocular foreign body injury is a relatively common and serious vision-threatening ocular trauma. Safe and effective removal of intraocular foreign body is the key to the treatment of intraocular foreign body injury. According to the nature of foreign bodies in the eye, foreign bodies can be divided into magnetic and non-magnetic foreign bodies. For magnetic foreign bodies, they are usually sucked out directly by the intraocular magnetic device or taken out by the external magnetic stick; for non-magnetic foreign bodies, they are mainly taken out with the assistance of foreign body tweezers, foreign body forceps, foreign body claws and other instruments. [0003] However, when foreign body tweezers, foreign body forceps or foreign body claws are used alone to grab fore...
