Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a vitrectomy transillumination press. Background Art

[0002] Vitreous surgery is a type of fundus surgery that is used to treat common fundus lesions that require surgery. The surgery is usually performed by two specialized doctors, a main surgeon and an assistant. The main surgeon is the main operator who completes most of the surgical work; the assistant assists with external pressure, handling instruments, and assisting in observation.

[0003] External pressure is performed with a metal pressure device, which can only be performed by an assistant to assist the surgeon. The surgeon needs the cooperation of the assistant to complete the operation, and the two must have a very high level of tacit understanding. In addition, vitrectomy requires separate fiber optic lighting, which is usually conducted by an optical fiber to guide the strong light into the fundus, and completes the lighting at the fundus like a flashlight, requiring the surgeon to use one hand to complete the lighting.

[0004] The above operation has the following disadvantages:

[0005] (1) Lighting cannot be completed while pressing;

[0006] (2) It is not possible to observe fundus lesions through transillumination, and the observation is not three-dimensional and comprehensive;

[0007] (3) External pressure and internal lighting each take up one hand, requiring the assistant to cooperate tacitly;

[0008] (4) Lack of backlighting from the outside to illuminate the eye tissue. Summary of the invention

[0009] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a vitrectomy transillumination pressure device, which can perform local pressure on the eyeball while providing light transmission from the outside, and observe the fundus through the wall of the eyeball.

[0010] The technical solution adopted by the present invention is as follows: a vitreous cutting transillumination pressing device, comprising a pressing device and an optical fiber arranged inside the pressing device. The pressing device is a tubular member with a predetermined length and inner diameter, and the two ends of the tubular member are respectively connected to a holding end and an operating end, and the holding end and the operating end are both hollow, and form a receiving chamber for the optical fiber to extend into with the hollow tubular member.

[0011] Furthermore, the working end of the pressing device is in the shape of a teardrop, and a frosted layer is arranged on the outer side. The working end of the pressing device has a predetermined working outer diameter and is used for pressing the eyeball.

[0012] Further, the connection between the holding end of the top presser and the tubular member is gradually inwardly converging, positioning the corresponding position of the optical fiber at a corresponding position away from the working end.

[0013] Further, the holding end and the working end are integrally formed with the tubular member.

[0014] Further, the top presser is made of a transparent material and has corresponding elasticity and hardness;

[0015] Further, the outer wall of the holding end is provided with anti-slip patterns, which can be realized by knurling technology, such as diamond-shaped anti-slip patterns, granular anti-slip patterns, grid-shaped anti-slip patterns, etc.

[0016] After adopting the above structure, the beneficial effects of the present invention are as follows: The device of the present application can perform local eye pressing and external light transmission illumination at the same time, observe the fundus through the eye wall, reduce the surgical instruments and operation steps required, meet the clinical needs of doctors, and the use of the device of the present application does not change the surgical habits, reduces the operation of the assistant, and makes the operation easier to complete; In addition, the device of the present application has a simple structure, low cost, and is convenient for processing.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0023] Vitrectomy is usually performed under a surgical microscope and a fundus observation microscope. It is a microsurgery. Usually, the light source of the microscope itself cannot provide sufficient illumination for the fundus, so a separate fiber optic illumination is required. During the operation, three channels are opened in the eyeball (in the non-retinal area of ​​the eyeball, i.e. 4-5mm behind the cornea), one of which is used to enter the illumination fiber for fundus illumination. However, the illumination fiber in the eye is very small and not strong enough, so the assistant needs to cooperate with the surgeon to adjust the illumination angle. Based on this, the inventors have designed a new method, such as Figure 1-2 The invention provides a vitreous cutting transillumination pressing device, which comprises a pressing device and an optical fiber arranged inside the pressing device. The pressing device is made of high temperature and high pressure resistant materials, which can be reused or disposable materials.

[0024] The presser is a tubular member 1 with a predetermined length and inner diameter. The two ends of the tubular member 1 are connected to a gripping end 3 and an operating end 2 respectively. The gripping end 3 and the operating end 2 are integrally formed with the tubular member 1 and are made of transparent material. The gripping end 3 and the operating end 2 are both hollow and form a receiving chamber 4 for the optical fiber to extend into with the hollow tubular member 1. The operating end 2 of the presser is in the shape of a water droplet and is provided with a frosted layer on the outside. The operating end 2 of the presser has a predetermined operating inner diameter and outer diameter. The presser can be made of colorless and transparent material for medical use, such as polyethylene material with a certain hardness and slight elasticity. It can apply force without breaking when pressing, and is light-transmissive. The frosted layer is provided on the outside of the operating end 2 to enhance diffuse light, increase the illumination of the eyeball wall, and increase friction when pressing the outer wall of the eyeball to prevent slipping.

[0025] In addition, the connection between the holding end 3 of the pusher and the tubular member 1 is gradually inwardly arranged, and its cross-section is V-shaped, which is convenient for clamping the handles of lighting optical fibers of different models from different manufacturers. Taking into account that the top of the holding device is easy to slip after the vitrectomy surgeon gets wet, the outer wall of the holding end 3 is provided with anti-slip texture to increase friction. Specifically, the anti-slip texture on the handle can be achieved by a knurling process, for example, it can be a diamond block anti-slip texture, granular anti-slip texture, grid-like anti-slip texture, etc.

[0026] The illumination optical fiber can adopt 20G, 23G, 25G, or 27G intraocular illumination optical fiber. The optical fiber extends into the operation end 2, and its handle part is clamped at the connection between the holding end 3 of the micro-elastic body and the tubular member 1.

[0027] Working principle: For the specifications of the device in this application, the overall length of the top presser can be 75 mm, and the wall thickness is 1.05 mm; the outer diameter of the tubular member 1 is 3 mm (it needs to match the currently used illumination optical fiber, and the inner diameter of the tubular member 1 here is 0.9 mm); the outer diameter of the operation end 2 is 6 mm, the outer diameter of the holding end 3 is 16 mm, and it gradually tapers inwards to 3 mm at the connection position of the tubular member 1.

[0028] During use, select a suitable illumination optical fiber, insert the head of the illumination optical fiber into the operation end 2 of the top presser, that is, make an external illumination light source. Through this external illumination light source, light can pass through the eyeball wall to observe the internal eye lesions, just like looking at an X-ray film. Illumination is achieved while the top pressing is completed. It can be operated with only one hand, eliminating the need for the cooperation of an assistant and making the operation more convenient.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural methods and embodiments without departing from the purpose of the present invention without creative efforts, they should all fall within the protection scope of the present invention. Each component of this application can be driven by a corresponding external motor, which is prior art and will not be elaborated in this application.
