Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a detachable medical endoscope lens. Background Technology

[0002] An endoscope is a diagnostic instrument that integrates traditional optics, ergonomics, and software. It can enter the stomach through the mouth or other natural orifices into the body. Endoscopes can be used to see lesions that cannot be seen by X-rays, making them very useful for doctors.

[0003] Patent CN208464027U discloses a medical endoscope. This medical endoscope uses a miniature ultraviolet generator on the operating part and optical fiber filaments on the inside of the infusion and aspiration tubing of the insertion tube. The ultraviolet rays generated by the miniature ultraviolet generator can be transmitted to the infusion and aspiration tubing through a second optical guide tube and optical fiber filaments to disinfect and sterilize the infusion and aspiration tubing with ultraviolet light. This can effectively prevent the growth of bacteria inside the infusion and aspiration tubing and provide a guarantee for the safe use of the endoscope.

[0004] In the existing technology, the lens of an endoscope is generally connected to the base by a thread. This connection method requires the lens to be turned continuously until the threads are completely disengaged, which is quite troublesome. Alternatively, the two can be fixed with screws. Regardless of the fixing method, installation and disassembly are quite troublesome. Therefore, a detachable medical endoscope lens is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a detachable medical endoscope lens to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable medical endoscope lens, comprising a base, an mounting sleeve and a fixing sleeve mounted on one side of the base, the mounting sleeve being fixedly mounted on one side of the base, a scope barrel being connected to one side of the mounting sleeve, a lens body being disposed on the scope barrel, a fixing sleeve being fixedly mounted inside the mounting sleeve, a shaped block being movably mounted inside the fixing sleeve, a movable rod being movably mounted inside the fixing sleeve, a roller being rotatably mounted on the inner end of the movable rod, an arc-shaped ball being fixedly mounted on the outer end of the movable rod, a mounting post being fixedly mounted inside the fixing sleeve, a compression spring being fixedly mounted on the outer side of the mounting post, and a movable groove being provided on the shaped block.

[0007] As a further preferred embodiment of this technical solution: a locking rod is fixedly installed inside the mounting sleeve, and a docking groove is provided on the outer side of the lens barrel, with the locking rod and the docking groove being docked together.

[0008] As a further preferred embodiment of this technical solution: one side of the lens barrel is provided with a mounting groove corresponding to the fixing sleeve, and the inner side of the mounting groove is provided with an arc-shaped groove corresponding to the arc-shaped ball.

[0009] As a further preferred embodiment of this technical solution: the fixed sleeve and the irregular block are movably installed together via a rotating shaft, and the outer side of the irregular block is provided with an arc-shaped surface corresponding to the roller.

[0010] As a further preferred embodiment of this technical solution: the movable rod is located inside the fixed sleeve and a limiting plate is fixedly installed on the outside of the movable rod.

[0011] As a further preferred embodiment of this technical solution: the compression spring is fixedly installed to the mounting column via a mounting sleeve, and one end of the compression spring is fixedly connected to the inner side of the movable groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the cooperation of a fixed sleeve, an arc-shaped surface, a movable rod, a mounting cylinder, and a compression spring, facilitates the docking of the lens barrel and the mounting sleeve. The docking groove and the locking rod are slidably installed, allowing one end of the lens barrel to be installed inside the mounting sleeve. The mounting groove is then installed on the outside of the fixed sleeve. During docking, the mounting groove presses against the top of the arc-shaped ball, allowing the movable rod to slide along the inside of the fixed sleeve. Simultaneously, the bottom of the movable rod rolls on the outside of the arc-shaped surface, and the irregular block rotates along the rotation axis. As the arc-shaped surface moves, the movable groove and the mounting post move closer together, compressing the compression spring. After the fixed sleeve and the mounting groove are docked, the spring's rebound pushes the movable rod outward, limiting the arc-shaped ball and the arc-shaped groove. This allows the lens barrel to be installed inside the mounting sleeve, making installation and disassembly more convenient. Attached Figure Description

The inner end of the fixed sleeve 2 is fixedly mounted with a mounting post 207, and the outer end of the mounting post 207 is fixedly mounted with a compression spring 209. The irregular block 201 is provided with a movable groove 210. The inner end of the mounting sleeve 101 is fixedly mounted with a locking rod 105. The outer end of the lens barrel 102 is provided with a docking groove 104, and the locking rod 105 and the docking groove 104 are docked together.

[0023] In this embodiment, specifically: the lens barrel 102 is connected to the mounting sleeve 101, and the docking groove 104 and the locking rod 105 are slidably installed so that one end of the lens barrel 102 is installed inside the mounting sleeve 101.

[0024] Example 2

[0025] Reference Figure 2 The lens barrel 102 has a mounting groove 106 corresponding to the fixed sleeve 2 on one side. The inner side of the mounting groove 106 has an arc groove 107 corresponding to the arc ball 205. The fixed sleeve 2 and the irregular block 201 are movably installed through the rotating shaft 202. The outer side of the irregular block 201 has an arc surface 203 corresponding to the roller 211.

[0026] In this embodiment, specifically: during the docking process, the mounting groove 106 can be pressed against the top of the arc-shaped ball 205, allowing the movable rod 204 to slide along the inside of the fixed sleeve 2, and allowing the bottom of the movable rod 204 to roll on the outside of the arc-shaped surface 203.

[0027] Reference Figure 2 The movable rod 204 is located inside the fixed sleeve 2 and the limiting plate 206 is fixedly installed on the outside of the movable rod 204. The compression spring 209 and the mounting column 207 are fixedly installed through the mounting cylinder 208. One end of the compression spring 209 is fixedly connected to the inside of the movable groove 210.

[0028] In this embodiment, specifically: the irregular block 201 can rotate along the rotating axis 202, and during the movement of the arc surface 203, the movable groove 210 and the mounting post 207 can move closer to each other, compressing the compression spring 209.
