Abstract
Description
Technical Field
[0001] This invention belongs to the field of endoscope technology and relates to a curved electronic eye endoscope. Background Technology
[0002] The purpose of posterior scleral reinforcement is to control further elongation of the axial length of the eye. This surgery typically involves a 3 / 4 circumference conjunctival incision behind the limbus. The reinforcement strip is introduced through this incision, traversing the scleral surface posteriorly, bypassing the macula, and finally exiting on the opposite side and sutured to the sclera. However, due to the narrow space and complex anatomy of the retrobulbar space, containing important structures such as the optic nerve and vortex veins, the path of the strip to the posterior pole of the eyeball is uncontrollable. Improper implant placement can easily cause direct mechanical compression of the optic nerve, leading to complications such as decreased vision or visual field defects. Once optic nerve damage occurs, an emergency secondary surgery is usually required within hours to adjust or release the strip.
[0003] Therefore, accurate visualization of the retrobulbar structures during surgery is crucial. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a curved electronic eye endoscope that facilitates access to the retrobulbar region.
[0005] The objective of this invention can be achieved through the following technical solutions:
[0006] A curved electronic ophthalmic endoscope includes a handle, an insertion part located at the front of the handle, and a camera module located at the front end of the insertion part. The insertion part is curved into an arc shape, the curvature of which matches the outer contour of the eyeball. The handle contains a light source and optical fibers. The light-emitting end of the optical fibers extends to the front end of the insertion part, and the light-incoming end of the optical fibers is aligned with the light source. A cable connector is detachably connected to the rear end of the handle. During use, the arc-shaped insertion part can be inserted around the surface of the eyeball, overcoming the obstruction of the eyeball, allowing the front end to reach the posterior region of the eyeball. The camera module provides clear and real-time visualization of the posterior region and its path.
[0007] The structural components inside the handle are arranged in a reasonable manner to make the structure compact and easier to assemble.
[0008] In the aforementioned curved electronic endoscope, a threaded hole is provided on the outer periphery of the handle, and a locking screw is threaded into the threaded hole. The inner end of the locking screw abuts against the light source. The light source is fixed by the locking screw. Correspondingly, a light source fixing component can be provided, on which the light source is mounted, with the inner end of the locking screw abutting against the outer periphery of the fixing component.
[0009] In the aforementioned curved electronic endoscope, the handle is provided with an irrigation channel extending to the front end face of the insertion part. The handle is equipped with a water connector, the inner end of which communicates with the rear end of the irrigation channel. Cleaning water is injected through the water connector and delivered to the front end of the insertion part via the irrigation channel for rinsing or cleaning the observation area.
[0010] In the aforementioned curved electronic endoscope, the handle also has an instrument channel extending to the front end face of the insertion part, and the handle has an instrument inlet communicating with the rear end of the instrument channel. Through the instrument channel, doctors can insert various specialized miniature instruments into the target area to complete diagnostic or treatment procedures.
[0011] In the aforementioned curved electronic eye endoscope, the light source is an LED.
[0012] Compared with existing technologies, this curved electronic eye endoscope has the following advantages:
[0013] By employing an arc-shaped insertion part that conforms to the contour of the eyeball, it can bypass the eyeball and directly reach the posterior region, enabling clear and real-time visualization of the posterior region. Scleral reinforcement surgery can be performed in a single procedure. It supports irrigation and minimally invasive operations, and its overall structure is compact, easy to assemble, and has good heat dissipation, significantly improving the feasibility, safety, and efficiency of ophthalmic surgery.

[0019] like Figure 1 The curved electronic endoscope shown includes a handle 1, an insertion part 2 located at the front of the handle 1, and a camera module 3 located at the front end of the insertion part 2. The signal line of the camera module 3 passes through the insertion part 2 and the handle 1 in sequence, and then connects to the main unit through a cable connected to the rear end of the handle 1.
[0020] The insertion part 2 is curved into an arc shape, and its curvature matches the outer contour of the eyeball. In use, the insertion part 2 can be inserted around the surface of the eyeball so that the front end of the insertion part 2 can reach the posterior region of the eyeball. In use, the insertion part 2 surrounds half of the eyeball.
[0021] In this embodiment, the cross-section of the insertion part 2 is cylindrical.
[0022] The arc-shaped insertion part 2 can enter along the surface of the eyeball during use, bypassing the obstruction of the eyeball, so that the front end of the insertion part 2 can reach the posterior region of the eyeball, and the camera module 3 can clearly and in real time visualize the path of the strip in the posterior region of the eyeball.
[0023] In this embodiment, the camera module is a full-color camera module.

The light source 4 is disposed on the light source fixing component.
[0026] A cable connector 6 is detachably connected to the rear end of the handle 1. It can be connected by means of threads, clips, etc. When the cable connector 6 is connected in place, the signal line and the wire of the light source 4 pass through the inner hole of the cable connector 6 and are connected to the host.
[0027] like Figure 2 and Figure 3 As shown, the handle 1 has an injection channel 7 extending to the front end face of the insertion part 2. The handle 1 is equipped with a water connector 8, the inner end of which is connected to the rear end of the injection channel 7. Cleaning water is injected through the water connector 8 and delivered to the front end of the insertion part 2 through the injection channel 7 for rinsing or cleaning the observation area.
