Description

Technical Field

[0001] This utility model belongs to the field of ophthalmic medical optical instruments, specifically relating to a handheld ophthalmic operating room angle observation device and an internal focusing observation system. Background Technology

[0002] Glaucoma is the leading cause of irreversible blindness worldwide, and its examination and treatment require meticulous examination and surgical procedures of the anterior chamber angle within the eyeball. Due to the unique anatomical location of the anterior chamber angle, it cannot be directly observed under normal circumstances, necessitating the use of a gonioscope. Patent CN201910393821.9 discloses an anterior chamber angle observation mirror, which, through lens surface design, can generate an upright virtual image of the anterior chamber angle tissue at a large angle to the optical axis of the eyeball, providing doctors with an angle and direction of observation for surgical procedures.

[0003] The technical problems with the above-mentioned solution are as follows: The surgeon needs to hold the observation mirror, requiring only one hand for surgical operations, making it inconvenient. Furthermore, as shown in the attached diagram, the lens uses a refractive optical path, resulting in a tilted optical path after imaging. Therefore, when used with a surgical microscope, the microscope's optical axis must also be adjusted to a tilted angle to receive an image. However, controlling the tilt angle of the surgical microscope is difficult, making it easy to miss the desired anterior chamber angle image, and repeated angle adjustments also affect surgical efficiency. Moreover, when the surgical microscope is tilted, focusing requires moving it, necessitating significant movement of the surgeon's position, further complicating the operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hand-free ophthalmic surgical angle observation device and an internal focusing observation system. This solves the problems of doctors needing to hold the observation mirror and only having one hand to perform surgical operations, which is not convenient. When used with a surgical microscope, the optical axis of the surgical microscope also needs to be adjusted to a tilted angle to receive an image. However, the angle of the tilted surgical microscope is difficult to control, and it is easy to fail to observe the required angle image.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] A handheld ophthalmic operating room angle observation device includes a support frame and an observation mirror mounted on the support frame. The support frame includes a mounting base, a support arm, and a connecting base connected in sequence. The mounting base is used to connect with a surgical microscope, and the connecting base is used to connect with the observation mirror. The support arm includes a first arm and a second arm hinged together. The observation mirror includes a first lens surface for contacting the cornea, a second lens surface for refracting the light path of the first lens surface, and a reflecting surface for reflecting the light path of the first or second lens surface. The reflecting surface is used to change the light path to a vertical direction.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. In this solution, the observation mirror is mounted on the surgical microscope using a bracket, eliminating the need for medical staff to hold the mirror by hand, thus freeing up their hands and making surgery easier. Furthermore, the support arms are designed with the first and second arms hinged together. When the mirror is placed on the eyeball, the support arms can provide appropriate safety cushioning when the position of the surgical microscope is adjusted or when the eyeball moves during surgery, preventing the mirror from pressing on the eyeball.

[0009] 2. In this solution, the observation mirror includes a reflecting surface for reflecting the light path of the first lens surface or the second lens surface. Through the reflection of the reflecting surface, the path of the tilted light path refracted by the first lens surface or the second lens surface can be adjusted, so that the path of the tilted light path changes. By designing the angle of the reflecting surface, the light path can be reflected into a vertical state, so that the angle of the surgical microscope no longer needs to be adjusted, making it easier for medical staff to operate.

[0010] Furthermore, the mounting base includes a base and a slide connected laterally to the base, with a support arm connected to the slide.

[0011] Furthermore, the mounting base includes a base and a rotating seat hinged to the base, with a support arm connected to the rotating seat.

[0012] Furthermore, the first arm is connected to the mounting base, and a flexible arm connects the second arm to the connecting base.

[0013] Furthermore, the observation mirror includes a lens and a reflector, the lens being used to form a first lens surface and a second lens surface, and the reflector being used to form a reflecting surface.

[0014] Furthermore, the observation mirror includes a lens, with two sides of the lens forming a first lens surface and a second lens surface. A reflective coating is provided inside the lens between the first lens surface and the second lens surface, and the reflective coating is used to form a reflective surface.

[0015] Furthermore, the reflective surface has two opposing points.

[0016] According to embodiments of this utility model, the following technical solutions are also adopted:

[0017] The internal focusing observation system includes a surgical microscope and a handheld ophthalmic operating room angle observation device, with a focusing component on the mounting base.

[0018] Furthermore, the mounting base can be detachably connected to the surgical microscope.

[0019] Furthermore, the focusing assembly includes a first focusing lens and a second focusing lens. The first focusing lens is fixed on the mounting base, and the second focusing lens is slidably connected to the mounting base along its axis. The first focusing lens is a negative lens, and the second focusing lens is a positive lens.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this solution, focusing can be achieved by sliding the second focusing lens through the setting of the focusing component, without moving the surgical microscope and observation mirror. This avoids the surgical microscope and observation mirror touching or pressing on the eyeball during movement, making the surgery safer. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0033] like Figure 1 As shown, the handheld ophthalmic operating room angle observation device includes a support frame and an observation mirror 6 mounted on the support frame. The support frame includes a mounting base, a support arm 4, and a connecting base 15 connected in sequence. The mounting base is used to connect to the surgical microscope 1, and the connecting base 15 is used to connect to the observation mirror 6. The observation mirror 6 can be fixed to the connecting base 15 in a conventional manner. The support arm 4 includes a first arm 2 and a second arm 3 hinged together. The first arm 2 is directly fixed to the mounting base, or installed on the mounting base through a conventional detachable connection method (e.g., bolt connection). Other connection methods can also be used for installation, as long as it can remain stable during the operation. The second arm 3 is connected to the observation mirror 6. In this embodiment, the second arm 3 is fixedly connected to the connecting base 15, or connected to the connecting base 15 through a conventional detachable connection method (e.g., bolt connection). Other connection methods can also be used for installation, as long as it can remain stable during the operation.

[0034] The observation lens 6 is fixed on the connecting base 15. The observation lens 6 includes a first lens surface 10 for contacting the cornea, a second lens surface 11 for refracting the light path of the first lens surface 10, and a reflective surface 12 for reflecting the light path of the first lens surface 10 or the second lens surface 11. The reflective surface 12 is used to change the light path to a vertical direction. Specifically, in this embodiment, two design methods for the reflective surface 12 are given as follows:

[0035] A1, combination Figure 2 As shown, the observation mirror 6 includes a lens 8 and a reflector 9. The lens 8 is used to form a first lens surface 10 and a second lens surface 11, and the reflector 9 is used to form a reflective surface 12. In this solution, the reflector 9 is independent of the lens 8. Therefore, the lens 8 can be directly selected from the lens in the prior art, such as the lens in patent CN201910393821.9 mentioned in the background art. Only the reflector 9 needs to be additionally installed on the connector 15, which makes it easy to directly modify and upgrade the prior art.

[0036] The reflector 9 is provided in two sets, that is, the reflector surface 12 is provided in two opposite places. After the reflector 9 reflects the light path refracted by the second lens surface 11, the light path is oriented in the vertical direction.

[0037] B1, combination Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the observation mirror 6 includes a lens 8. The two sides of the lens 8 form a first lens surface 10 and a second lens surface 11. A reflective coating is provided inside the lens 8 between the first lens surface 10 and the second lens surface 11, forming a reflective surface 12. In this design, the lens 8 is modified by coating the connecting surface between the first lens surface 10 and the second lens surface 11 with a silver or aluminum reflective coating to form the reflective surface 12. The light refracted from the first lens surface 10 is first reflected by the reflective surface 12 and then refracted by the second lens surface 11, ensuring the light path is vertical.

[0038] In this embodiment, various design methods for the lens 8 are given. For example, the second lens surface 11 can be a plane (see...). Figure 4 , Figure 6 (as shown) or a convex surface that is not coaxial with the optical path of the first lens surface 10 (see...) Figure 3 , Figure 5 As shown), the two opposing reflective surfaces 12 can be a combination of a flat surface on one side and an inclined surface on the other side (see...). Figure 3 , Figure 4 , Figure 5 As shown), it can also be a completely symmetrical design with one side consisting of a plane and an inclined plane (see...). Figure 6 (As shown). In actual design, as long as the goal of oriented the light path vertically can be achieved, other methods can be adopted for the angle design of the second lens surface 11 and the reflecting surface 12, which will not be listed one by one in this embodiment.

[0039] In another embodiment of this utility model, to avoid the problem that the observation lens 6 would obstruct the operation of medical personnel when it is not needed after being mounted on the surgical microscope 1, this embodiment provides two mounting base designs as follows:

[0040] A2, such as Figure 7As shown, the mounting base includes a base 13 and a slide 14 slidably connected to the base 13 laterally. The support arm 4 is connected to the slide 14. Specifically, the base 13 has a transverse slide rail, and the slide 14 is slidably connected to the slide rail. In actual design, the slide 14 can be driven to slide using a cylinder (as in existing technology), or it can be driven to slide using conventional screw structures or other mechanical principles. By sliding the slide 14, it can be positioned directly below or offset from the surgical microscope 1. Combined with the relative movement of the first arm 2 and the second arm 3, the observation mirror 6 can be adjusted to no longer obstruct the operation of medical personnel.

[0041] B2, such as Figure 8 As shown, the mounting base includes a base 13 and a rotating seat 16 hinged to the base 13. The support arm 4 is connected to the rotating seat 16. In actual design, a motor used in the prior art to drive the rotation of the rotating seat 16 can be installed on the base 13, or the rotation of the rotating seat 16 can be driven by other conventional mechanical structures. By rotating the rotating seat 16, it can be positioned directly below the surgical microscope 1 or offset from directly below the surgical microscope 1, allowing the observation mirror 6 to be adjusted so as not to obstruct the operation of medical personnel.

[0042] In another embodiment of this utility model, such as Figure 1 As shown, in order to further improve the safety buffering effect and prevent the observation lens 6 from pressing on the eyeball 7, the first arm 2 is connected to the mounting base, and the second arm 3 is connected to the connecting base 15 with a flexible arm 5. In the actual design process, the flexible arm 5 can be made of multiple strands of steel wire twisted together, so that it has a deformation effect and can be maintained after deformation. Alternatively, the flexible arm 5 can be made of rubber material. As long as it has a certain deformation capacity, the connecting base 15 can move relative to the second arm 3 to a certain extent, thereby improving the safety buffering effect.

[0043] In another embodiment of this utility model, such as Figure 7 , Figure 8 , Figure 9 As shown, an internal focusing observation system is also disclosed, including a surgical microscope 1 and a handheld ophthalmic operating room angle observation device as described in any of the foregoing embodiments. The mounting base is detachably connected to the lens of the surgical microscope 1. Specifically, the base 13 of the mounting base can be bolted to the surgical microscope 1. The detachable connection facilitates the replacement of the handheld ophthalmic operating room angle observation device, or the surgical microscope 1 can be used alone without the handheld ophthalmic operating room angle observation device installed.

[0044] The mounting base is equipped with a focusing assembly. Specifically, the focusing assembly is set on the slide 14 or the rotating base 16. The focusing assembly includes a first focusing lens 17 and a second focusing lens 18. The first focusing lens 17 is fixed on the mounting base (i.e., the slide 14 or the rotating base 16), and the second focusing lens 18 is slidably connected to the mounting base (i.e., the slide 14 or the rotating base 16) along its axis. In actual design, a mounting ring is fixed to the outer wall of the second focusing lens 18. The mounting ring is slidably connected to the slide 14 or the rotating base 16. The mounting ring can be driven to slide by a cylinder in the prior art, or the sliding of the mounting ring can be achieved by using conventional screw structures and other mechanical principles.

[0045] The first focusing lens 17 is a negative lens 8, and the second focusing lens 18 is a positive lens 8. In specific applications, such as... Figure 9 As shown, a focal plane is formed below the first focusing lens 17. The second focusing lens 18 can change the position of the focal plane during movement. When the second focusing lens 18 moves in the direction of the optical axis, the focal plane moves downward synchronously, so that the focal plane below the first focusing lens 17 coincides with the image plane of the observation lens 6, achieving an internal focusing effect. Meanwhile, the observation lens 6 can remain stationary, avoiding contact or pressure on the eyeball 7 during the movement of the surgical microscope 1 or the observation lens 6, making the surgery safer.
