The objective is to be able to rotate smoothly and smoothly and to perform surgery safely and in a short time. [Arrangement] On the side surface of the angled lens body (1) of a contact lens used for intraocular vitreous body surgery, a plurality of columnar arbitrary convex portions (2) for finger hooking (2) having a flat rectangular shape or an arbitrary shape are provided. , A contact lens for intravitreal vitreous surgery, characterized by being integrally formed with the same material as the angled lens body at appropriate intervals.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a new contact lens for intravitreal surgery, which allows an operating surgeon to perform surgery without an assistant in intravitreal surgery.

[0002]

[Prior Art]

 In the case of conventional vitreous surgery, which is related to the vitreous body in the eyeball, contact lenses are necessary, with some exceptions, when observing the fundus and the area around the fundus with a surgical microscope. This is the so-called contact lens for vitreous surgery, which consists of several types of contact lenses and a ring. The method of use is to sew a ring that holds the contact lens on the cornea, and then contact lens adapted for the purpose of observation. The surgeon operates with a scalpel inserted in the vitreous body and an illuminating fiber with both hands while observing with a microscope from above. Therefore, at that time, since the surgeon has both hands closed, the assistant operates the contact lens as needed.

The conventional surgical contact lens in such a vitreous surgery has a cylindrical lens body with a handle made of metal or the like attached thereto by adhesion or the like (hereinafter referred to as “handled lens”), or a handle. There is only the lens body without a lens attached (hereinafter referred to as “non-patterned lens”). The patterned lens is operated by pinching the patterned part and the unpatterned lens both sides of the column with tweezers. there were.

Among such conventional contact lenses for vitreous surgery, there is a lens (hereinafter, referred to as “angled lens”) in which the upper surface of the lens is angled with respect to the horizontal in order to particularly observe the peripheral part of the fundus. However, with this type of lens, the observation area varies depending on the rotation of the lens.Therefore, when using this lens, the surgeon must instruct the assistant to use the tweezers for both the patterned lens and unpatterned lens. It is necessary to rotate the lens to the position where you want to observe it, but it has the drawback that the position often shifts and it takes time, and the surgeon himself holds the surgical tool in both hands and uses the finger to move the lens arbitrarily. There is a drawback that even if you try to rotate it to the position, it does not take force as you want and you can not rotate it freely, especially if you need an emergency surgery without an assistant, This is not suitable when you want to shorten the operation time as much as possible to reduce the burden on the patient. Furthermore, in the case of a lens with a handle, the handle may break or come off during use.

[0005]

[Problems to be solved by the device]

 According to the present invention, in the conventional contact lens for vitreous surgery described above, the operation cannot be performed without an assistant and the operation cannot be performed smoothly, so not only the operation takes time, but the handle is broken or damaged during the operation. It is an object of the present invention to provide a contact lens for vitreous surgery, which can eliminate the drawbacks such as falling off and impeding surgery.

[0006]

[Means for Solving the Problems]

 Therefore, in the present invention, after various research and trial production, on the outer peripheral surface of the cylindrical side portion of the angled lens body (1) of the contact lens for vitreous surgery, an arbitrary number of arbitrary shapes made of the same material as the lens are provided. By forming the convex portion (2) integrally with the lens main body (1), the surgeon holds the surgical tool in both hands while holding the surgical tool in place, without using the assistant's hand We have developed a contact lens for intravitreal vitreous surgery with a convex portion for finger hanging that allows free rotation while operating, and has solved the above problems.

[0007]

[Action]

 While holding the surgical tool in both hands, the surgeon of the vitreous surgery hooks his or her arbitrary fingertip on the convex portion provided on the side outer peripheral surface of the angled lens body to rotate the lens. The lens can be swiftly and smoothly rotated to the position to be observed without the assistance of an assistant, and vitreous surgery can be performed safely and in a short time.

Unlike the conventional handle, the finger-holding convex portion (2) is formed integrally with the angled lens body (1), so that it does not break or fall off during use.

Since the finger-holding convex portions (2) are arranged on the outer peripheral surface of the side surface of the angled lens body (1) at an appropriate interval in any number, the surgeon can easily put his fingertip on either of them. You can observe the vitreous body while freely rotating the lens.

Since the convex portion (2) for finger hanging is integrally molded with the same material (transparent acrylic resin product) as the angled lens body (1), it does not hinder the observation of the surgeon. effective.

[0011]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to this. As shown in FIG. 1, a plurality of fingers (in the present embodiment, there are twelve, but the number can be increased or decreased as appropriate) in the shape of a rectangular column on the side outer peripheral surface of the angled lens body (1) of the contact lens for vitreous surgery. The present invention is completed by integrally providing the convex portion (2) for the lens body with the same material (acrylic resin product) as the lens body. The finger-hanging convex portion (2) may be in the shape of a square column or a circular column as shown in FIG. 4 (a) or (b).

[0012]

[Effect of the device]

 INDUSTRIAL APPLICABILITY The present invention enables a surgeon to operate a lens by himself / herself without an assistant in a vitreous surgery, carefully observing the vitreous body, and safely and swiftly performing the surgery. It is remarkable, especially in the case of emergency surgery when there is no assistant, and it can be said that it is useful in the era of shortage of nurses recently. Further, since the angled lens body and the finger-holding convex portion are integrally formed in the lens of the present invention, there is no risk of the handle being broken or coming off like a conventional lens with a handle, and the handle can be removed during surgery. There are some products that prevent troubles due to breakage, falling out, etc., have excellent durability, withstand long-term use, and have a great economic effect.
