Abstract
The utility model discloses a pair of long tube-type surgical forceps for an eye deep under a microscope, which comprises a miniature left clamping piece (1) and a miniature right clamping piece (2) and is characterized in that the rear parts of the miniature left clamping piece (1) and the miniature right clamping piece (2) are fixed on a left wall and a right wall of the front mouth rim of a square pipe casing (4) through pin shafts (3) respectively; a tension spring (5) is arranged between the rear ends of the miniature left clamping piece (1) and the miniature right clamping piece (2); two ultra-high molecular weight polyethylene fibers (6 and 7) are arranged in a cavity of the square pipe casing (4); the front ends of the two ultra-high molecular weight polyethylene fibers are respectively fixedly connected with the middle parts of the miniature left clamping piece (1) and the miniature right clamping piece (2), and the rear ends of the two ultra-high molecular weight polyethylene fibers move round a middle shaft (8) and are then fixedly connected with the middle part of a pull rod (9); and the two ends of the pull rod (9) extend out of side wall holes (10) formed on the square pipe casing (4). The volume of a head of the long tube-type surgical forceps is small, and the opening degree is small when the surgical forceps stretch into the eye deep, so that the long tube-type surgical forceps are easy to stretch into the eye deep; in addition, the transmission can be completed through the fibers, so that the structure is simple, the operation is flexible, and the use is convenient. The long tube-type surgical forceps can be widely applied to ophthalmic microsurgeries.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of depths microscopically long tube formula surgical forceps.
Background technology
When doing the operation of deeps such as detachment of retina operation or vitreous body at ophthalmology, because operative site is darker, the art open country is less, need carry out at microscopically, this operation, and it is meticulous to perform the operation, and otch is small.At present still use common small cusp tweezer in operation, grasping tissue or blood vessel are because common small cusp tweezer, though head is point, can stretch in the little otch, it is big that the tweezer mouth opens amplitude, cause otch to enlarge, do not reach the purpose that stretches into little otch grasping tissue or blood vessel at microscopically.
Summary of the invention
The purpose of this utility model be to provide a kind of otch small, use flexibly, be particularly suitable for carrying out the eye depths microscopically long tube formula surgical forceps of a depths operation at microscopically.
For reaching above purpose, the technical scheme that this utility model adopted is: this depths microscopically long tube formula surgical forceps, by a miniature left side, right clamping piece constitutes, it is characterized in that a miniature left side, the rear portion of right clamping piece is fixed on the left side on square tube housing prosopyle edge respectively by bearing pin, on the right wall, on a miniature left side, be provided with extension spring between the rear end of right clamping piece, intracavity at the square tube housing is provided with two superhigh molecular weight polyethylene fibers silks, the front end of a superhigh molecular weight polyethylene fibers silk is fixedly connected on the middle part of miniature right clamping piece, the middle part that axis is fixedly connected on pull bar is walked around in its rear end, the front end of another root superhigh molecular weight polyethylene fibers silk is fixed on the middle part of miniature left intermediate plate, the middle part that axis also fixedly is connected in pull bar is walked around in its rear end, stretch out from the areole of square tube housing at the two ends of pull bar, is provided with the disc type lever in the rear end of square tube housing.
This utility model is also implemented by following measure: the intracavity at the square tube housing also is provided with optical fibers, rear end at the intracavity of square tube housing is provided with button-type battery and midget lamp, fibre-optic front end is bonded and fixed on the inwall of miniature left intermediate plate middle part, fibre-optic rear end extends midget lamp, and the switch of midget lamp is located on the wall of square tube housing; The cross section of described square tube housing is a rectangle, and its length is 6-8mm, and its width is 4-6mm; Also be provided with deflector apron on the described pull bar.
The beneficial effects of the utility model are: with at present in the delicate procedure of ophthalmology deep employed surgical forceps compare, its head volume is little, it is little to dehisce when stretching into, so stretch into easily; Because superfine superhigh molecular weight polyethylene fibers silk has been adopted in the transmission of power, so it is very thin that the square tube housing can be done.And simple in structure, flexible operation, easy to use.Can be widely used in ophthalmology deep microscopically delicate procedure.
