Description

Ophthalmology iris peritomy micro-sharp nose pliers

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to micro-sharp nose pliers of ophthalmology iris peritomy.

Background

In ophthalmic vitreous cutting operation, for complicated fundus operation, after the operation, the vitreous cavity is often filled with silicone oil as a vitreous substitute, so that the detached retina can be restored. For the eyes with lens defects, after the eyes are subjected to anterior-posterior chamber communication and silicone oil filling operation, silicone oil easily enters the anterior chamber due to the posture and the gravity action of the silicone oil, the chamber angle is filled with the silicone oil, the outflow of aqueous humor is blocked, and secondary ocular hypertension is caused. In order to avoid silicone oil from entering the anterior chamber clinically, peripheral incisions are usually made at the root of the iris at six points below the anterior chamber to form a drainage opening, and the prone position is matched after the operation, so that aqueous humor in the posterior chamber flows into the anterior chamber, and the aqueous humor flows out through the chamber angle to achieve intraocular pressure balance. Currently, the lower iris root tissue is cut clinically by using a vitrectomy head, and a peripheral incision is formed artificially. When the peripheral incision of the iris is performed by the vitrectomy head, different shapes are frequently cut due to different experience and manipulation of each person, the control of the cutting suction is poor, the peripheral incision is easily too large or too small, double pupils and pupil displacement occur, even large blood vessels are cut off, secondary anterior hemorrhage is caused, and the probability of secondary blockage of the peripheral incision is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an ophthalmological iris peritomy micro-sharp-nose pliers, which can enter eyes through a small corneal incision to clamp the root of an iris and is convenient for operation; can control cutting force, and can avoid the conditions of double pupils, pupil displacement, secondary anterior chamber bleeding and secondary blockage of peripheral incision.

In order to achieve the above purpose, the utility model adopts the following technical scheme: it contains first pointed end, the pointed end of second, connecting piece, left hand handle, right hand handle, spring coupling spare, the top at first pointed end be provided with first incision, first incision is the sharp incision of arc, the pointed top of second is provided with the second incision, the second incision is the sharp incision of arc, first pointed end is connected with the upper end of left hand handle, the pointed end of second is connected with the upper end of right hand handle, it is articulated through the connecting piece between left hand handle and the right hand handle, form the cross structure of X type, the one end of spring is fixed on the right hand handle, the other end of spring is fixed on the left hand handle, spring coupling spare sets up on left hand handle or one of them spring of right hand handle.

The structure of the first notch is the same as that of the second notch.

The spring is fixed on different horizontal positions of the left handle and the right handle.

The length of the left handle is longer than that of the first tip.

The length of the right handle is longer than that of the second tip.

The spring connecting piece is an adjusting screw, and the tightness of the spring can be adjusted. For those with hypertrophic iris tissue, the adjusting screw can be rotated counterclockwise to expand the distance between the left and right handles in order to expand the opening formed by the first tip and the second tip. The utility model discloses a theory of operation: the first tip and the second tip form a pair of micro-nipper pliers, the arc sharp cuts of the first cut and the second cut enable the pair of micro-nipper pliers to enter the anterior chamber of an eye through a 2mm corneal limbus cut when the pair of micro-nipper pliers is closed, and then open to enter the iris root part below the eye, and then close the pair of micro-nipper pliers to cut iris tissues, and meanwhile, the pair of micro-nipper pliers can be repeatedly used, and can avoid bleeding of the eye when pressurized, the spring controls the opening of the left handle and the right handle, and controls the opening and closing of the left handle and the right handle through the compression elastic force of the spring and the hand use force in a matching way, so that the force used when the pair of micro-nipper pliers is used can be controlled, the spring has the function of controlling the force, the clamping is labor-saving, the cutting force can be well controlled by the pair of micro-nipper pliers in the, the situation that the peripheral incision is blocked again due to the fact that large blood vessels are cut off to cause secondary intracameral hemorrhage makes the peripheral incision of the iris more firm after the ophthalmic vitreous body cutting operation.

After adopting above-mentioned technical scheme, compare in current glass crop head iris week and cut the technique and have following effect:

the utility model discloses micro-sharp-nosed pliers is cut all around to ophthalmology iris adopts the first most advanced and the second most advanced that have the sharp-pointed incision of arc to make things convenient for the intercepting iris tissue, through left hand handle, the structure that can open and shut that first most advanced and second most advanced formation X type is connected to right hand handle, can make things convenient for the operation in-process to control first most advanced and second most advanced, especially left hand handle reaches and has to set up the spring between the handle, elasticity through the spring makes left hand handle and right hand handle and first most advanced, the second most advanced remains open state throughout, make the centre gripping more laborsaving, make things convenient for the operation, when carrying out the all cut of iris, the easy control cutting strength, make the all cut size of iris comparatively unified, the security is higher, ophthalmic surgery is more firm, and the utility model discloses.
