Description

Technical Field

[0001] The utility model relates to the field of ophthalmic surgical instruments, in particular to a pressing device sleeved on the front end of a vitrectomy illumination optical fiber. Background Art

[0002] During ophthalmic vitrectomy surgery, an illumination optical fiber is required. The illumination optical fiber consists of a handle and an optical fiber at the front end of the handle. The optical fiber is a light-conducting medium made of glass or plastic fibers. It can achieve long-distance illumination by using the principle of total internal reflection of light. Since the optical fiber is small in size, has good light transmittance, and is not easy to block the line of sight of the surgeon, and at the same time enables the surgeon to clearly see the vitreous body in the eye, the illumination optical fiber plays an important role in vitrectomy surgery.

[0003] However, during vitrectomy surgery, the surgeon needs to hold the vitrectomy cutter in one hand to cut the vitreous body and hold the illumination optical fiber in the other hand for illumination. An additional assistant is required to externally press the eyeball wall (sclera) to make the patient's eyeball rotate, so that the surgeon can observe the internal situation of the eye at an appropriate angle and excise the peripheral vitreous body. This operation requires the two to cooperate tacitly. If the pressing height is insufficient, the surgeon may miss cutting part of the vitreous body; if the pressing is too high, it may cause iatrogenic holes, resulting in the risk of surgical failure. Therefore, a pressing device sleeved on the front end of the vitrectomy illumination optical fiber is proposed, enabling the surgeon to independently complete the pressing and illumination work with one hand, improving the efficiency and success rate of the surgery. Summary of the Utility Model

[0004] The utility model aims to provide a pressing device sleeved on the front end of a vitrectomy illumination optical fiber to solve the problem that vitrectomy surgery requires the cooperation of the surgeon and an assistant to complete the operations of cutting the vitreous body, pressing the eyeball, and illuminating the eye interior.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A pressing device sleeved on the front end of a vitrectomy illumination optical fiber includes a main body, a pressing part, and a sleeve component. A first cavity for accommodating the optical fiber and a second cavity for accommodating the handle are provided inside the main body. The first cavity and the second cavity are in a communicating relationship. The rear end of the second cavity is in communication with the external environment. A pressing part is provided at the front end of the main body. The pressing part surrounds the front end of the first cavity. The pressing part is made of a material with high light transmittance. A sleeve component sleeved on the handle is provided at the rear end of the main body.

[0007] A further technical solution is that the main body is made of a tough material with high light transmittance.

[0008] A further technical solution is that the pressing part is in an ellipsoidal shape.

[0009] Further technical solution: The first cavity is in the shape of a cylinder, and the cross-section of the cylinder can ensure that the optical fiber inserted into the first cavity passes through. The length of the first cavity is equal to the length of the optical fiber.

[0010] Further technical solution: The inner contour of the second cavity fits the contour of the handle.

[0011] Further technical solution: The sleeve component is made of elastic rubber material, and the sleeve component and the handle form an interference fit.

[0012] Further technical solution: Anti-slip patterns are provided both inside and outside the sleeve component.

[0013] Further technical solution: The main body, the pressing part and the sleeve component are integrally connected.

[0014] Principle and beneficial effects of this technical solution:

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] The whole of the present utility model is in a sleeve structure and can be sleeved on the illumination optical fiber used in the existing vitrectomy surgery. The first cavity accommodates the optical fiber to enter, so that the head of the optical fiber reaches the pressing part, enabling the pressing part to have both illumination and pressing functions at the same time. This allows the surgeon to complete the pressing and illumination actions with one hand and the cutting action of the vitreous body with the other hand, solving the problem that the vitrectomy surgery requires the surgeon and the assistant to cooperate tacitly to complete the actions of cutting the vitreous body, pressing the eyeball and illuminating the eye cavity, and improving the efficiency and success rate of the surgery.

[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments:

[0022] As Figure 1-2As shown in the figure, a pressing device sleeved on the front end of a vitrectomy illumination optical fiber includes a main body 1, a pressing part 2 and a sleeve component 3. A first cavity 4 for accommodating the optical fiber 7 and a second cavity 5 for accommodating part of the handle 8 are arranged inside the main body 1. The first cavity 4 and the second cavity 5 are in a communicating relationship, and the rear end of the second cavity 5 communicates with the external environment. The illumination optical fiber 7 is inserted from the rear end of the second cavity 5 so that the optical fiber 7 enters the first cavity 4 to complete the assembly. The pressing part 2 is arranged at the front end of the main body 1. The pressing part 2 is ellipsoidal and surrounds the front end of the first cavity 4. The pressing part 2 is made of a material with high light transmittance, which can make the light at the head of the optical fiber 7 penetrate through the pressing top, so that the pressing part 2 has both pressing and illumination functions at the same time. A sleeve component 3 sleeved on the handle 8 is arranged at the rear end of the main body 1, so that the utility model is fixed on the handle 8 of the illumination optical fiber 7.

[0023] The main body 1 is made of a ductile material with high light transmittance. The high light transmittance of the main body 1 is convenient for observing whether the inserted optical fiber 7 smoothly enters the first cavity 4 when installing the utility model, and the main body 1 made of a ductile material can effectively protect the optical fiber 7.

[0024] The first cavity 4 is cylindrical, and the cross-section of the cylinder can ensure that the optical fiber 7 inserted into the first cavity 4 passes through. The length of the first cavity 4 is equal to the length of the optical fiber 7, which ensures that the optical fiber 7 can smoothly enter the first cavity 4, and the head of the optical fiber 7 can be effectively combined with the pressing top.

[0025] The internal contour of the second cavity 5 fits the contour of the handle 8, so that the utility model is not easy to deform and slide after installation.

[0026] The sleeve component 3 is made of an elastic rubber material. The sleeve component 3 and the handle 8 form an interference fit, so that the utility model is firmly fixed to the handle 8 and is not easy to fall off.

[0027] Anti-slip patterns 6 are arranged both inside and outside the sleeve component 3. The anti-slip pattern 6 inside the sleeve further increases the friction between the sleeve and the handle 8, and the anti-slip pattern 6 outside the sleeve makes it not easy for the main surgeon to slip when holding.

[0028] The main body 1, the pressing part 2 and the sleeve component 3 are integrally connected. The integral design is convenient for disassembly and disinfection.

[0029] The specific implementation process is as follows:

[0030] Insert the illumination optical fiber 7 into the present utility model from the rear end of the second cavity 5, so that the optical fiber 7 enters the first cavity 4. The head of the optical fiber 7 is combined with the pressing top part. Relying on the high light transmittance of the pressing part 2, the pressing part 2 has the functions of illumination and pressing at the same time, enabling the surgeon to complete the pressing and illumination actions with one hand and the vitreous cutting action with the other hand, solving the problem that the vitrectomy operation requires the surgeon and the assistant to cooperate tacitly to complete the actions of cutting the vitreous body, pressing the eyeball and illuminating the eye interior, and improving the operation efficiency and success rate.

[0031] The above are only the embodiments of the present utility model. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
