Description

Technical Field

[0001] This utility model belongs to the field of medical supplies technology, and in particular to a gonioscope for minimally invasive glaucoma surgery. Background Technology

[0002] In ophthalmic surgery, doctors often need to observe the angle of the anterior chamber. One method is to use an indirect gonioscope (or simply gonioscope, gonioscope) in conjunction with a slit-lamp biological microscope. For optimal observation, the gonioscope needs to be able to examine both the left and right eyes. Traditionally, it is flipped and hinged for use. However, some gonioscopes are designed with handles. When the handle is facing downwards, it's difficult to effectively examine both eyes simultaneously.

[0003] A search revealed a Chinese patent document (authorization announcement number CN221469838U) for a direct gonioscope that utilizes the principle of double reflection. By combining the angles of two reflecting mirrors, a magnified, upright image of the anterior chamber angle structure can be observed under direct vision, matching the observation angle. The clamp-on handle facilitates lens manipulation, allowing the lower lens surface to better conform to the corneal surface for optimal observation. When performing anterior chamber angle-related procedures under a microscope, there is no need to tilt the surgical microscope or adjust the patient's position / eye position, offering advantages such as ease of operation, time savings, and reduced surgical complications. The direct gonioscope can be reused after sterilization, reducing operating costs. While gonioscopes with handles are convenient to use, when the handle is facing downwards, it's difficult to effectively examine both eyes simultaneously. Utility Model Content

[0004] The purpose of this invention is to provide a gonioscope for minimally invasive glaucoma surgery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gonioscope for minimally invasive glaucoma surgery, comprising:

[0006] The endoscope body for preoperative examination of minimally invasive glaucoma surgery;

[0007] The C-shaped fixed lug is rotatably connected to the endoscope body at the anterior chamber angle via a rotating component;

[0008] Handheld component, fixedly connected to the fixed lifting lug, for the operator to hold;

[0009] A threaded tube, internally installed on the outer periphery of a fixed lifting lug;

[0010] The T-shaped threaded rod is threaded to the threaded pipe. Two symmetrically arranged limiting tubes are embedded in the outer circumference of the rotating part. The end of the threaded rod is set in one of the limiting tubes to limit and fix the limiting tube and the endoscope body.

[0011] As a preferred embodiment, the rotating component includes:

[0012] The movable sleeve is rotatably connected to the body of the gonioscope via a bearing;

[0013] Two fixed tubes are fixedly connected to the movable sleeve and abut against the inner wall of the fixed lifting lug;

[0020] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0021] This minimally invasive glaucoma surgery uses a gonioscope. Through a rotating component, the gonioscope body can be rotated relative to the fixed lug to meet different usage needs. Using bearings, the gonioscope body can be rotated relative to the fixed lug, changing the rotation angle of the gonioscope body to meet the examination needs of the left and right eyes. The threaded rod passes through the limiting tube at the adjacent position to ensure the stability of the gonioscope body.

[0022] This minimally invasive glaucoma surgery uses a gonioscope. The threaded rod can fix the limiting tube and the gonioscope body. After the blocking plate of the rotating part is opened, the limiting rod can be removed, which makes it easy to disassemble the gonioscope body and to disinfect and replace the gonioscope body.

[0023] This minimally invasive glaucoma surgery uses a gonioscope with a convenient handheld device. By rotating the handheld tube, the distance between the handheld tube and the gonioscope body can be changed to meet different usage needs.

[0039] Please see Figures 1 to 4 As shown, a gonioscope for minimally invasive glaucoma surgery, in this embodiment, includes:

[0040] The gonioscopic endoscope body 1 is used for preoperative examination of minimally invasive glaucoma surgery.

[0041] The C-shaped fixed lug 2 is rotatably connected to the endoscopic body 1 of the anterior chamber angle via the rotating part 3. The width of the endoscopic body 1 of the anterior chamber angle is smaller than the width of the fixed lug 2 to meet the flipping requirements. When flipping is required, the threaded rod 7 is taken out, the endoscopic body 1 of the anterior chamber angle is rotated, and then the threaded rod 7 is used for fixation.

[0042] Handheld component 4 is fixedly connected to the fixed lifting lug 2 and is used by the operator for holding.

[0043] Threaded pipe 5 is embedded in the outer periphery of fixed lifting lug 2;

[0044] The T-shaped threaded rod 7 is threadedly connected to the threaded tube 5. Two symmetrically arranged limiting tubes 8 are embedded in the outer circumference of the rotating part 3. The end of the threaded rod 7 is set in one of the limiting tubes 8 to limit and fix the limiting tube 8 and the endoscope body 1. The rotating bearing causes the endoscope body 1 to rotate relative to the fixed lug 2, changing the rotation angle of the endoscope body 1. The threaded rod 7 is used to press and fix the endoscope body 2, ensuring the stability of the endoscope body 1.

[0045] Rotating component 3 includes:

[0046] The movable sleeve 35 is rotatably connected to the endoscope body 1 of the anterior chamber angle via a bearing. The width of the endoscope body 1 of the anterior chamber angle is smaller than the width of the fixed lug 2 to meet the rotation requirements.

[0047] Two fixed tubes 31 are fixedly connected to the movable sleeve 35 and abut against the inner wall of the fixed lug 2;

[0048] Two auxiliary tubes 32 are embedded in both sides of the fixed lifting lug 2;

[0049] Two limiting rods 33 are set inside the auxiliary tube 32 and the fixed tube 31. Both auxiliary tubes 32 are rotatably connected to a blocking plate 34 for blocking the limiting rods 33. The blocking plate 34 is connected and fixed to the auxiliary tube 32 by a latch.

[0050] The handheld component 4 includes a threaded connecting rod 41 that is inclinedly connected to the fixed lifting lug 2, and a handheld tube 42 that is threadedly connected to the threaded connecting rod 41. The outer periphery of the handheld tube 42 is bonded with an anti-slip sleeve 43. By rotating the handheld tube 42, the distance between the handheld tube 42 and the endoscopic body 1 of the anterior chamber angle can be changed.

[0051] Working principle

[0052] This minimally invasive glaucoma surgery uses a gonioscope. By rotating the handheld tube 42, the distance between the handheld tube 42 and the gonioscope body 1 is changed. By rotating the bearing, the gonioscope body 1 rotates relative to the fixed lug 2, changing the rotation angle of the gonioscope body 1. The threaded rod 7 is used to tighten and fix the gonioscope body 2, ensuring the stability of the gonioscope body 1. When it is necessary to flip it, the threaded rod 7 is removed, the gonioscope body 1 is rotated, and then the threaded rod 7 is used to fix it.
