Description

Intraocular tweezers

technical field

The invention relates to the field of medical instruments, in particular to an intraocular scissor tweezers used for ophthalmic surgery.

Background technique

The eyeball consists of the cornea, iris, lens, and retina. In ophthalmic surgery, forceps and surgical scissors are commonly used surgical tools. In the process of ophthalmic surgery, the ophthalmologist often needs to alternately use the above two surgical tools to enter and exit the eyeball during the operation, which greatly wastes the ophthalmologist's treatment time and energy. At the same time, due to the complexity of the eyeball structure, frequent replacement of surgical tools in and out of the eyeball also increases the risk of eyeball injury. Therefore, for delicate ophthalmic surgery, a more optimally designed surgical tool is urgently needed.

Utility model content

The purpose of the utility model is to provide an optimally designed tweezers tool.

In order to achieve the above purpose, the present utility model proposes an intraocular tweezers tool for ophthalmic surgery, which includes a grippable body part and a working part that can partially extend into the eye; the working part includes a tweezers head and A support arm; it is characterized in that, the tweezers head comprises a first tweezers tip and a second tweezers tip which are oppositely arranged; the first tweezers tip comprises a first tweezers part and a first tweezers part connected to it, The second scissor tweezer tip includes a second scissor portion and a second tweezer portion connected thereto.

Since the cutting forceps tip has both a cutting portion for cutting and a forceps portion for tearing, a surgical instrument has a cutting function and a tearing or gripping function at the same time. When performing delicate eye surgery, ophthalmologists no longer need to frequently replace surgical scissors and surgical forceps in and out of the eyeball under microscopic conditions, which greatly saves operation time and energy, makes delicate surgery more smoothly, and reduces surgery risk.

Preferably, a first cutting edge and a first cavity are provided on the inner surface of the first shearing portion; a second cutting edge and a second cavity are provided on the inner surface of the second cutting portion; the first cutting edge can be Being accommodated in the second cavity, the second cutting edge can be accommodated in the first cavity.

During intraocular surgery, when cutting or segmenting some ocular tissues in the eye, the first cutting edge cooperates with the second cutting edge to complete the cutting or segmenting work. Since the space inside the eye is very limited, during the shearing process, the relative opening and closing range of the first blade and the second blade is greatly limited, and the opening and closing range affects the shearing function. By arranging the first cavity and the second cavity, the opening and closing range of the first blade and the second blade in the shearing process can be enlarged, and the shearing function can be better realized.

In addition, when using the first tweezers part and the second tweezers part to realize the tweezers function, during the folding process of the first tweezers part and the second tweezers part, the first blade and the second blade can be respectively accommodated in the The first concave cavity and the second concave cavity will not prevent the first forceps portion and the second forceps portion from being folded, so as to better realize the function of the forceps.

Preferably, the first cutting edge is arranged opposite to the second cavity; the second cutting edge is arranged opposite to the first cavity.

Preferably, the first forceps portion and the second forceps portion are both hook-shaped.

Both the first tweezers part and the second tweezers part extend with a certain arc to form a hook shape.

In addition, the radial widths of the tweezer tips of the first tweezers part and the second tweezers part gradually become smaller, which is helpful for better tearing or grasping the tissue in the eye.

Preferably, the heads of the first forceps portion and the second forceps portion are both blunt.

In this way, other intraocular tissues are not easily damaged when the forceps are operated.

Preferably, along the axial direction of the intraocular tweezers, the first scissors and the first tweezers are connected in sequence, and the first tweezers are disposed farther away from the first scissors The end of the body part; the second scissors and the second tweezers are connected in sequence, and the second tweezers are arranged at the end farther from the body part than the second scissors.

Preferably, the working part further comprises a base, and the support arm is connected to the base.

Preferably, the head of the body part is provided with a locking device, and the base is connected to the body part through the locking device.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Referring to FIG. 1, a specific embodiment of the present invention includes a scissors tool for intraocular surgery, which includes a grippable body portion 1 and a working portion that can partially extend into the eye, the working portion Including the scissors head 2 and the support arm 3. The material of the body portion 1 is a titanium alloy material, which has high strength, good corrosion resistance and high heat resistance. The type of the tweezers head 2 is straight micro-tweezers, and the material is stainless steel. The body portion 1 includes a groove 11 and a clamping arm 12 . There are two grooves 11 , which are respectively disposed on both sides of the body portion 1 . The two sides in the groove 12 are slope-shaped, the bottom surface is horizontal, and the whole is in the shape of a boat, so that when the tweezers tool is used, the body part 1 is more suitable for the palm and is easy to be held. There are two clamp arms 12 , which are attached to the front end of the main body portion 1 . One end of the clip arm 12 is fixed on the body part 1, and the other end is suspended in the air, so that the ophthalmologist can operate and apply force more easily during use.
