Technical Field
The utility model relates to the technical field of medical equipment, in particular to multifunctional instrument for retinal surgery.
Background
Vitreoretinal surgery is an important surgical method for solving various fundus diseases, and the vitreoretinal surgery field is developed rapidly through decades of development from the vitreocutting machine invented by Machemer of Americans in the 70 th generation of the 20 th century. Machemer originally used 17G (1.5 mm diameter) transpars plana vitrectomy multifunctional instruments that required a fiber optic cuff, and the procedure required a 2.3 mm scleral incision, and in 1974 OMalley and Heitz designed a thin vitrectomy head with a diameter of 0.9mm (20G, 0.9mm instrument diameter), and this less invasive three channel 20G catheter system has been used to date, and still physicians using this system, and now dominated by 23G (0.6 mm instrument diameter) and 25G (0.5 mm instrument diameter) vitrectomy systems. The 23G or 25G microsurgical system has a higher cutting frequency and suction force than the conventional vitrectomy system. The matched series of vitreoretinal microsurgical instruments comprise a vitrectomy head, a light guide fiber, an intraocular micro forceps, an intraocular electric coagulator, a microscope observation system and the like, and the instruments are finer and more complicated than the instruments used for the traditional vitreoretinal microsurgical operation.
In vitreoretinal surgery, it is often necessary to perform vitrectomy or removal of proliferative membranes from the anterior retinal surface of the peripheral area, as well as laser photocoagulation. Since the eyeball is a sphere, the manipulation of the peripheral region often requires the use of pressure against the outer sclera to allow for the observation and manipulation of the peripheral structures. Clinically, the conventional solution at present is that an assistant holds the contact lens with the left hand, and the assistant presses the contact lens in the operation with the sclera pressing device on the right hand, and a doctor of the main surgeon observes and operates the eyes with the sclera pressing device, which requires the assistant to have a skilled skill for pressing the sclera.
Therefore, how to reduce the difficulty of pressing the retina in the existing vitreoretinal surgery is a technical problem to be solved urgently by those skilled in the art.
