Problems solved by technology

[0002] At present, the scissors used in ophthalmic surgery have been continuously improved and can be conveniently used in the operation. However, because the head structure of the scissors cannot get rid of the structural constraints of traditional scissors, it cannot cut deeply in small incisions, making its The scope of use is limited, which brings certain difficulties to the operation
For example, in the intracapsular intraocular lens implantation operation, the anterior capsule is usually torn open with micro forceps, so the operation is difficult, the safety performance is poor, and the success rate is low

Abstract

The invention belongs to the field of surgical instruments, and in particular provides a microscopic intraocular instrument. The microscopic intraocular instrument comprises a handle, a connection part and a head part, wherein the handle and the head part are respectively fixed at two ends of the connection part; the handle and the connection part are detachably connected; the head part and the connection part are detachably connected; the head part comprises tongs; the tongs comprise two scissoring bodies; and the two scissoring bodies can displace relatively so as to form clamping force together. The microscopic intraocular instrument disclosed by the invention provides a plurality of different head part scissor structures, therefore, different surgical and operation requirements can be satisfied; furthermore, because various parts in the microscopic intraocular instrument are detachably connected with each other, a part of parts can be only changed or replaced in need of changing or replacing a certain part, the whole body of the microscopic intraocular instrument is unnecessary to change or replace, and thus, the sustainable utilization rate can be greatly increased.

Description

technical field [0001] The invention belongs to the field of surgical instruments, and more specifically, the invention belongs to a microscopic intraocular scissors used in ophthalmology. Background technique [0002] At present, the scissors used in ophthalmic surgery have been continuously improved and can be conveniently used in the operation. However, because the head structure of the scissors cannot get rid of the structural constraints of traditional scissors, it cannot cut deeply in small incisions, making its The scope of use is limited, which brings certain difficulties to the operation. For example, in the intracapsular intraocular lens implantation operation, the anterior capsule is usually torn open with micro forceps, so the operation is difficult, the safety performance is poor, and the success rate is low. In some vitreous cutting and intraball foreign body removal operations, if the scissors can be cut deep into the ball, the safety and reliability of the o...
