When the outer tube body 41 is inserted into the patient's body, the doctor can observe the patient's internal condition through the first oblique tube 13 and its internal structure.

[0021] The outer tube body 41 houses a shaped tube 42, an inner tube body 43, an optical system 44, an optical fiber body 45, and a water pipe 46. A set of connectors 521 is mounted on the top of the main body 40. A camera connection section is mounted on the top of each connector 521. The camera connection section includes an optical fiber connector 32, a green ring 33, an optical fiber shortening 34, an ACMI connector 35, a light taper 36, a WOLF connector 37, and a STORZ connector 38. These connectors are installed sequentially from bottom to top inside the housing of the camera connection section. The optical fiber connector 32 is connected to the optical fiber body 45. The camera connection section can connect to an external camera. The external camera is connected to the optical system 44 sequentially via the optical fiber connector 32, green ring 33, optical fiber shortening 34, ACMI connector 35, light taper 36, WOLF connector 37, and STORZ connector 38. The camera can display the image information detected by the outer tube body 41.

[0022] The oblique tube 13 houses an eyepiece tube 3, an adjustment seat 4, an aperture seat 5, a compression spring 7, a base 8, a pressure cap 9, and a centering ring 12. The compression spring 7 is installed between the aperture seat 5 and the base 8. A sealing ring 10 is installed on the outside of the oblique tube 13. An oblique inner tube 14 is installed on the inside of the centering ring 12. One end of the oblique inner tube 14 is connected to the base 8, and the other end of the oblique inner tube 14 is connected to the optical system 44. The main body 2 40 houses a mechanical tube 31, a sealing gasket 51, an inner nut 52, and an oblique tube 2 53. The oblique tube 2 53 is connected to the optical system 44, and the mechanical tube 31 is connected to the shaped tube 42. The sealing gasket 51 and the inner nut 52 are located between the mechanical tube 31 and the oblique tube 2. On the outside of 53, the bottom of the main body 2 40 is equipped with an outer tube seat 54 and a four-way connector 39. The top of the oblique tube 1 13 forms an eyepiece cover 1. The inside of the oblique tube 1 13 is equipped with a protective plate 2. The inside of the oblique tube 1 13 is provided with a slotted conical end set screw 6 and a rear connector 11. The inside of the main body 2 40 is equipped with a sealing ring 3 23, an inner tube seat 24, a fixing bolt 25, an adjusting nut 26, a prism seat 27, a three-way connector 28, and a sealing ring 4 29. The sealing ring 4 29 is installed between the positioning plate 30 and the main body 2 40. The three-way connector 28 is installed at the bottom of the main body 2 40. The inner tube seat 24, the fixing bolt 25, and the adjusting nut 26 are installed inside the main body 2 40 and located outside the positioning plate 30.

[0023] Through the above technical solution, the oblique tube 13 supports and fixes the oblique inner tube 14. The doctor observes the information transported inside the oblique inner tube 14 through the eyepiece tube 3 via the protective plate 2. The compression spring 7 supports the aperture seat 5, making it easy to install the aperture seat 5 at different depths. The pressure cap 9 supports the top of the oblique inner tube 14. The medical tube 31 and the special-shaped tube 42 are connected. The two ends of the oblique tube 2 53 are connected to the optical system 44 and the oblique inner tube 14, respectively. The sealing gasket 51 and the inner nut 52 support the oblique tube 2 53 and the medical tube 31, making the oblique tube 2 53 and the medical tube 31 more stable. The inner tube seat 24 and the fixing bolt 25 support the oblique tube 2 53 and the medical tube 31 at the same time, preventing one end of the oblique tube 2 53 and the medical tube 31 from shaking. The tee 28 is located at the bottom of the prism seat 27. The adjusting nut 26 is connected to the medical tube 31. The sealing ring 4 29 makes the positioning plate 30 and the main body 2 40 more tightly connected.

[0024] Specifically, a cylinder 22 is installed at the other end of the main body 2 40. Inside the cylinder 22, a main body 1 16, a magnetic block 17, a main body cap 18, a magnetic sheet 19, a connecting bolt 20, and a sealing ring 21 are installed. The main body cap 18 is installed inside the magnetic sheet 19. The main body 1 16 is installed at the other end of the cylinder 22. An instrument channel connector 55 is installed at the other end of the cylinder 22. An I-shaped sealing cap 15 is installed at the other end of the instrument channel connector 55. The I-shaped sealing cap 15 is connected to the cylinder 22 through another set of connecting seats 521. A left instrument valve 56 is installed inside the I-shaped sealing cap 15.

[0025] Through the above technical solution, the magnetic block 17 and the magnetic sheet 19 together form a magnetic component. The magnetic component is usually used with a magnetic capsule endoscope or a magnetically assisted endoscope system to achieve precise control and positioning of the endoscope. The instrument channel connector 55 is used to connect to the I-shaped sealing cap 15. After the left instrument valve 56 is opened, the instrument can enter the instrument tube 31 and the irregular tube 42 through the tube inside the I-shaped sealing cap 15, thereby removing the patient's stones and polyps.

[0026] Specifically, valve connection 1 48 and valve connection 2 49 are installed on both sides of the main body 2 40. A left water valve 47 is installed at the end of valve connection 1 48 that is away from the main body 2 40, and a right water valve 50 is installed at the end of valve connection 2 49 that is away from the main body 2 40.

[0027] Through the above technical solution, the left water valve 47 and the right water valve 50 can be connected to external pipes. Water enters the water pipe 46 through valve connection 1 48 and valve connection 2 49. The water flow sprayed from the water pipe 46 cleans the abdominal cavity after surgery. At the same time, the water pipe 46 can also aspirate abdominal fluid to remove the fluid. The fluid and stones / polyps are extracted, making the stones / polyps clean and without causing adverse reactions in the patient.

[0028] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
