Abstract
Description
Technical Field
[0001] This utility model relates to a rigid endoscope for microscopy. Background Technology
[0002] While rigid microendoscopy offers advantages such as high observational precision and the elimination of the need for puncture sampling, its inflexible nature makes it less convenient to operate. Furthermore, insertion into human organs can trigger stress and discomfort in patients. For example, laryngoscopes and otoscopes present similar problems when inserted into the larynx or ear canal. Summary of the Invention
[0003] The purpose of this invention is to provide a steering knuckle for a rigid microendoscopy, which has a certain bending angle and can transmit light signals. It can be used in conjunction with a rigid microendoscopy, making the rigid microendoscopy bendable for easy use.
[0004] The present invention relates to a steering joint for a rigid microendoscopy, comprising a rod lens assembly and an elbow; the rod lens assembly includes a first rod lens for forming parallel light emitted from a point and a second rod lens for converging the parallel light into a point; the two ends of the elbow are respectively connected to the first rod lens and the second rod lens, the optical axes of the first rod lens and the second rod lens are not coaxial; a steering prism is provided inside the elbow; the incident light emitted from a point passes through the first rod lens and is formed into parallel light parallel to the optical axis of the first rod lens, and after being deflected by the steering prism, it forms parallel light parallel to the optical axis of the second rod lens, which then enters the second rod lens and converges into a point.
[0005] The aforementioned rigid microendoscopy steering knuckle has one end of rod lens one and rod lens two connected to the two ends of the elbow by threads, and the other end of rod lens one and rod lens two also have threaded connections.
[0006] The aforementioned rigid microendoscopy steering knuckle has a 100° bend.
[0007] The aforementioned rigid microendoscopy steering knuckle has a 120° bend.
[0008] The aforementioned rigid microendoscopy steering knuckle has a 160° bend.
[0009] This invention also provides a rigid microendoscopy endoscope, which is bent in shape, making it easy to operate and convenient to insert into different organs for examination, while also being easy to assemble and disassemble.
[0010] The rigid endoscope of this invention has a steering knuckle for the rigid endoscope, and the objective lens is connected to a rod lens 1. The image formed by the objective lens is emitted as parallel light parallel to the optical axis of the rod lens 1 after passing through the rod lens 1. After being turned by the steering prism, parallel light parallel to the optical axis of the rod lens 2 is emitted into the rod lens 2 and converges to a point after passing through the rod lens 2.
[0011] The aforementioned rigid microendoscopy objective lens and rod lens are connected by a threaded structure.
[0012] The aforementioned rigid microendoscopy rod endoscope is connected to a handle via a threaded structure, and the handle has an optical path system that is connected to the main unit.
[0013] The beneficial effects of this utility model are:
[0014] Rod mirrors are existing technology, capable of directing light rays into parallel beams or converging parallel beams. This invention uses two rod mirrors (forming a rod mirror assembly) connected to both ends of a bend. The bend is located on the parallel light path between the two rod mirrors. Thus, the steering prism only redirects the light path without changing the image position. Therefore, when used in conjunction with a rigid microendoscopy, it does not affect the imaging of the objective lens within the rigid microendoscopy. Because of its bend, the rigid microendoscopy has an overall bent portion, rather than a straight line, facilitating operation and use, and allowing for insertion into different organs for examination.
[0015] For easier assembly and disassembly, one end of both rod lens one and rod lens two are threaded to the two ends of the elbow, and the other end of both rod lens one and rod lens two has a threaded connection part. The threaded connection parts of rod lens one and rod lens two are used to connect with different external components.
[0016] Elbows are available in different angles such as 100°, 120°, and 160°, and can be selected and used according to actual needs.
[0017] Steering prisms are existing technology, such as pentagonal prisms. Attached Figure Description
[0018] Figure 1 This is a schematic diagram of a rigid microendoscopy endoscope. Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] See Figure 1 The rigid microendoscopy shown comprises a steering knuckle 100 consisting of a rod lens group 1, an elbow 2, a steering prism 3, etc., an objective lens 5, a handle 6, a main unit 7, etc.
[0021] The rod lens assembly 1 includes a first rod lens 11 for forming parallel light emitted from a point into a point for output, and a second rod lens 12 for converging the parallel light into a point; the two ends of the elbow 2 with a through hole inside are respectively connected to the outer shell 13 of the first rod lens 11 and the outer shell 14 of the second rod lens 12 by threads, and the optical axes of the first rod lens and the second rod lens are not coaxial; a steering prism 3 is provided inside the elbow 2.
[0022] The outer ring 51 of objective lens 5 is connected to the outer shell 13 of rod lens 11 via a threaded structure. The outer shell 14 of rod lens 2 12 is connected to handle 6 via a threaded structure, and handle 6 has a flexible optical path system connected to main unit 7.
[0023] The image formed by the objective lens is emitted as parallel light parallel to the optical axis of the first bar lens. After being deflected by the turning prism, it is emitted as parallel light parallel to the optical axis of the second bar lens. The light then converges to a point after passing through the second bar lens and enters the main unit for imaging through the optical path system.
[0024] Elbow 2 can be 100° (e.g.) Figure 1 (As shown), bends at different angles such as 120° and 160°.

Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
