Auxiliary frame of push injection device for intraocular lens implantation surgery

Abstract

An auxiliary frame of a push injection device for intraocular lens implantation surgery relates to an auxiliary surgical instrument. A loosening screw B (71) is arranged on the lower bottom surface ofa U-shaped clamping slot (69) and penetrates the lower bottom surface of the U-shaped clamping slot (69), and a top plate B (70) is arranged on the inner end of the loosening screw B (71). Accordingto the present invention, an auxiliary frame capable of being supported and fastened on an operating table surface for the push injection device for intraocular lens implantation surgery is provided,so as to avoid the problem that the height of the hand-held push injection device is uncertain and the push injection angle cannot be accurately determined; by setting a mode of horizontal and vertical staggered sliding, the flexible sliding of the push injection device can be realized, the three-dimensional spatial position adjustment of the push injection device and a process control or angle control device matched with the push injection device can be realized, and the standardization and normalization of the intraocular lens implantation surgery process can be realized; and the risk of surgical treatment can be greatly reduced, and a necessary auxiliary device for the precise injection of the push injection device is provided when interns or medical college students carry out the intraocular lens injection surgery.

Description

technical field [0001] The invention relates to an auxiliary device for artificial lens implantation, in particular to an auxiliary frame for injection device for artificial lens implantation. Background technique [0002] It is well known that the intraocular lens is currently the most effective method for correcting the refraction of aphakic eyes. It replaces the original lens anatomically and optically, and constitutes a nearly normal system, especially the one fixed in the normal physiological position of the lens. Posterior chamber intraocular lens. It can be used for one eye, and the visual acuity can be restored quickly after operation, and it is easy to establish binocular monovision and stereopsis. According to the different materials of IOLs, IOLs are divided into hard IOLs formed of hard materials and soft IOLs. Soft IOLs are also called foldable IOLs. When using a rigid IOL, the surgical incision should be at least 6 mm wide at the time of implantation. In c...

Problems solved by technology

[0006] In order to overcome the deficiencies in the background technology, the present invention discloses an auxiliary frame for injection device for intraocular lens implantation surgery. , to avoid the problem that the height of the bolus injection device cannot be accurately determined when the bolus injection device is in the hands. By setting the horizontal and vertical sliding, the flexible sliding of the bolus injection device can be realized, and the process control or matching of the bolus injection device and the bolus injection device can be realized. The three-dimensional space position adjustment of the angle control device, adding an auxiliary frame on the basis of the process control or angle control device on the bolus injection device, can play the role of supporting the bolus injection device and facilitate the doctor to flexibly control the propulsion height and the distance of the propeller And the propeller angle, etc., to realize the standardization and standardization of the operation process of intraocular lens implantation, greatly reduce the risk of surgery and medical treatment, and provide the necessary practice auxiliary equipment for the intern doctor or medical student to perform the intraocular lens injection operation with the injector.
