Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to an angle mirror, and particularly relates to an angle mirror without adjusting the angle of a microscope. BACKGROUND

[0002] The angle mirror is a kind of medical apparatus and instruments for ophthalmic examination and operation, and can be used for observing the structure of eyes through a microscope or a magnifying glass. The angle mirror is usually composed of a thin sheet-shaped lens, a light source, a microscope or a magnifying glass, etc., can divide the eyeball into two parts of an anterior chamber and a posterior chamber, and enable doctors to observe the detailed conditions of the structure in eyes. In ophthalmic examination, the angle mirror is usually used for checking the diagnosis and treatment of diseases such as glaucoma, cataract and retinal diseases, and can help doctors to judge the type and degree of diseases and to make reasonable treatment plans.

[0003] The utility model discloses a position adjustable angle mirror, which comprises a bracket, a movable frame, an angle mirror, etc. Figure 1 The movable frame is movably arranged in the adjusting groove, and the inner extension plate is integrally connected to one side of the adjusting plate. The angle mirror comprises a first lens body rotatably installed between the inner extension plates, a second lens body integrally connected to one side of the top of the first lens body, an inner recess formed in one side of the first lens body and an outer convex portion formed in one side of the second lens body. The movable frame can be appropriately adjusted in position when the eye is diagnosed, so that the structure in the eye can be observed by the doctor to the greatest extent. The floating arrangement of the angle mirror can better cooperate with the lying posture of the patient, can reduce the pressure on the cornea, can avoid the deformation of the anterior chamber, and can ensure that the doctor can observe a clear angle image. The angle mirror of the application comprises a single cylindrical lens. When an observer needs to observe the anterior chamber angle, the microscope needs to be rotated by an angle A (as shown in the figure), at this time, the microscope is not on the same optical axis as the eye axis, the posture of the observer is very awkward, and after adjusting the position of the angle mirror, the microscope also needs to be adjusted, which seriously affects the speed of operation.

[0022] The utility model will be further described below in combination with the embodiments shown in the drawings.

[0023] As Figure 2 shown, the gonioscope without adjusting the angle of the microscope mainly comprises the rotating mounting sleeve 1, the handle 2 and the optical lens group 3 and the like in cooperation.

[0024] Among them, as Figure 3 shown, the rotating mounting sleeve 1 comprises the sleeve body 11 and at least one convex ring body 12 (the convex ring body 12 has the coincident axis with the sleeve body 11) formed (usually integrally formed) on the peripheral surface of the sleeve body 11, and the surface of the convex ring body 12 is covered with the anti-skid convex 121. In the embodiment, the convex ring body 12 is multiple (specifically two) and is arranged at intervals, so that the adjacent two convex ring bodies 12 have the accommodating space 13.

[0025] The handle 2 is rotatably installed on the rotating mounting sleeve 1. As Figure 4 shown, the handle 2 comprises the clamping hook 21 (the clamping hook 21 has the notch, so that the clamping hook 21 can be clamped into the aforementioned accommodating space through the notch, and the relative movement between the clamping hook 21 and the sleeve body 11 is not affected), the handle rod 23 arranged on one side of the clamping hook 21 and the adapter rod 22 connecting the clamping hook 21 and the handle rod (23), and the plane where the clamping hook 21 is located and the handle rod 23 form an acute angle, usually 30~50°. In the embodiment, the handle rod 23 comprises the rod body 231, the adapter 232 integrally formed at the end of the rod body 231 and gradually reducing in diameter outward, and the multiple anti-skid grooves 233 arranged at intervals on the peripheral surface of the rod body 231 and adjacent to the adapter 232, at this time, the clamping hook 21 and the adapter 232 are smoothly connected through the adapter rod 22. In this way, when the operator needs to rotate the rotating mounting sleeve 1 to drive the optical lens group 3 to rotate, the handle 2 will not affect such operation.

[0026] The optical lens set 3 is installed on the rotating installation sleeve 1, and is used in cooperation with a microscope to observe an angle of the anterior chamber (such as an angle of the anterior chamber). The optical lens set 3 at least comprises an optical lens body 31 (which is made of a conventional optical glass with a high refractive index available on the market). The top surface 311 of the optical lens body 31 is a convex surface, and the bottom surface 312 is a concave surface matched with the cornea. Meanwhile, the optical lens body 31 has a first side surface 313 and a second side surface 314 arranged oppositely (i.e. the optical lens body 31 has a peripheral surface between the convex surface and the concave surface, and the first side surface 313 and the second side surface 314 are located on the peripheral surface), and the first side surface 313 and the second side surface 314 are respectively coated surfaces (such as silver-coated surfaces). In use, as shown in Figure 6 , the concave surface is in contact with the cornea, and the pattern of the angle of the anterior chamber is refracted into the optical lens through the concave surface, and is reflected through the two coated surfaces and is refracted out of the optical lens through the convex surface. At this time, the light path is parallel to the optical axis, and the microscope is located directly above the eyeball, so that the complete angle of the anterior chamber can be observed. Moreover, the rotating lens can be used to observe the angle of the anterior chamber at 360°, and the angle of the microscope does not need to be adjusted, which is convenient, fast and ensures the speed of the operation.

[0027] In the embodiment, as shown in Figure 5 , the optical lens set 3 further comprises a first lens 32 and a second lens 33 matched with the optical lens body 31. Specifically, the second side surface 314 of the optical lens body 31 is formed with a convex part protruding from the second side surface 314, so that a stepped structure is formed between the second side surface 314 and the convex part. Thus, the first lens 32 can be supported on the optical lens body 31 (i.e. supported at the aforementioned stepped structure) and closely abut against the second side surface 314 (i.e. closely abut together), and the second lens 33 closely abuts against the first side surface 313. It is also preferred that the top surfaces of the first lens 32 and the second lens 33 form a large arc surface with the same curvature as the top surface 311 of the optical lens body 31, and the bottom surface of the second lens 33 does not contact the cornea. At this time, the optical lens set 3 is composed of three lenses, the middle one is the optical lens body 31, and the two sides are ordinary lenses (i.e. the first lens 32 and the second lens 33). The light path passes through the silver-coated surfaces (i.e. forms the first side surface 313 and the second side surface 314) on both sides of the optical lens body 31, which ensures the clarity of light reflection and facilitates the installation of the optical lens set 3 in the rotating installation sleeve 1. Moreover, the first side surface 313 and the second side surface 314 are respectively located on both sides of the optical axis, one side (the right side in Figure 6 ) is parallel to the optical axis, and the other side (the left side in Figure 6 ) forms an angle of 20-30° (preferably 28°) with the optical axis. The center of the convex surface deviates from the optical axis, which ensures that the light out of the lens is parallel to the optical axis, and the image is magnified by about 1.2 times, which improves the observation effect of the angle of the anterior chamber.

[0028] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
