Iris retractor assembly device

Abstract

This invention discloses an iris retractor assembly, comprising an iris retractor and an iris retractor auxiliary implanter. The iris retractor has a closed-loop structure, with both ends being blunt, rounded, and smooth without barbs. The injection end of the iris retractor auxiliary implanter has a Y-shaped structure, which can push and pull the two ends of the iris retractor together to narrow them for entry into a smaller corneal-scleral incision or removal from the eye. The iris retractor in this device has a continuous closed-loop structure, and the retractor head is a "U" or "V" shaped shield-like structure without barbs. This structure ensures that the iris and lens capsule are not punctured or damaged during surgery. Furthermore, the retractor head in this device has a two-end design (one end of the retractor rod has a large U-shaped or large V-shaped structure, and the other end has a small U-shaped or small V-shaped structure). This design allows the surgeon to select different sizes according to the traction requirements during surgery.

Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an iris retractor assembly device. Background Art

[0002] Cataract is the eye disease with the highest blindness rate among the elderly, and surgical treatment is currently the most effective method. In order to fully expose the surgical interface, it is necessary to ensure that the pupil is large enough during the operation. Before the operation, it is necessary to select appropriate drugs to dilate the pupil. During the operation, high molecular weight viscoelastics can be injected into the anterior chamber to dilate the pupil through mechanical pressure on the pupil. However, in difficult and complex cataract surgeries, small pupils and iris adhesions often occur. The above methods cannot effectively dilate the pupil. In the case of a small pupil, the surgical operation is difficult and risky. If not handled properly, it is very likely to cause a variety of complications and adverse consequences.

[0003] Mechanical traction during surgery can effectively adjust the pupil size. The commonly used method is to first make a puncture around the cornea and then insert an adjustable nylon retractor with an adjustable silicone fixing sleeve. However, in practical observations, it is found that the puncture incision is often blocked by small blood clots or pressure differences inside and outside the eye during the operation gap between the puncture incision and the insertion of the iris retractor. It is necessary to make another puncture incision, repeat the surgical steps, or force the iris retractor into the incision under strong resistance, which can easily cause eye damage.

[0004] Chinese patent CN201120327668.9 discloses an iris retractor, which is composed of a retractor handle, a retractor rod, a circular silicone sheet and a triangular retractor; the characteristics are: a retractor handle is made at one end of the retractor rod, a triangular retractor is made at the other end of the retractor rod, a circular silicone sheet is mounted on the retractor rod, and the circular silicone sheet can slide on the retractor rod; the upper and lower surfaces of the triangular retractor are both triangular, and the upper and lower triangles are transitioned by arcs. It can be seen that the current lens capsule bag or iris retractor is mostly a fishhook-like "J" shape design, the hook-pulling structure is simple and unscientific, it is difficult to enter or remove the eye, the pointed part at one end is easy to puncture and damage the iris lens capsule, the range of hook-pulling iris is limited, and it is easy to fold and deform to damage the intraocular tissue. Summary of the invention

[0005] The main purpose of the present invention is to provide an iris retractor assembly device to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an iris retractor assembly device, comprising an iris retractor and an iris retractor auxiliary implanter, wherein the iris retractor is a closed-loop structure, and both ends of the iris retractor are blunt and smooth structures without hooks or thorns; the pushing end of the iris retractor auxiliary implanter is a Y-shaped structure, and the pushing end of the iris retractor auxiliary implanter can push and pull the two ends of the iris retractor and make them close together and thinner so as to enter a smaller corneal scleral incision or be removed from the eye.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the iris hook includes a hook rod, a slider is slidably connected to the hook rod, both ends of the hook rod are hook heads with blunt and smooth structures without hook barbs, and the hook head includes a first hook head and a second hook head.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the first hook head is a large U-shaped structure or a large V-shaped structure, and the second hook head is a small U-shaped structure or a small V-shaped structure.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the size of the slider is adapted to the size of the incision during surgery, the diameter of the slider is 2.5-4.5 mm, and the thickness of the slider is 1-2 mm.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the iris retractor-assisted implanter includes a connecting rod, one end of which is fixedly connected to the bottom of the push end of the iris retractor-assisted implanter, and the other end is fixedly connected to the handle.

[0011] The beneficial effects of the present invention are as follows:

[0012] (1) The iris retractor in the device is constructed in a continuous closed loop, and the retractor head of the iris retractor is a "U" or "V" shaped, barbed, blunt, smooth structure, which can ensure that the iris and lens capsule are not punctured or damaged during surgery.

[0013] (2) The retractor head in this device is a two-end design (one end of the retractor rod is a large U-shaped structure or a large V-shaped structure, and the other end is a small U-shaped structure or a small V-shaped structure). This structural design allows the doctor to choose different sizes according to the traction requirements during the operation.

[0014] (3) The iris retractor in the present device is equipped with a clothes-hanging fork-like "Y"-shaped iris retractor auxiliary implanter, which can push the "U" or "V" part of the retractor head, thereby making it easier to insert or remove the iris retractor into or out of the eye. The "Y"-shaped iris retractor auxiliary implanter pushes, pushes and pulls the "U" or "V" part of the iris retractor head, making it closer and thinner, thereby making it easier to enter or remove from the eye through a smaller corneal scleral incision.
