Endoscopes can visualize lesions that cannot be seen by X-rays, making them extremely useful for doctors. With the help of endoscopes, doctors can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly. Confocal microscopy provides high-definition microscopic endoscopic examination at the cellular level in real time. It integrates a miniaturized confocal laser microscope into the endoscope lens. While performing ordinary white light endoscopy, microscopic examination can be performed using confocal laser scanning technology, realizing a deeper development of in vivo imaging from macroscopic to microscopic.

[0003] While current endoscopes can be used to examine the human body, the procedure requires the patient to open their mouth before the endoscope is inserted. Due to the size of the endoscope, patients may experience discomfort and close their mouths, which can affect the movement of the endoscope, reduce examination efficiency, and ultimately decrease its practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a multi-cavity endoscope capable of simultaneously performing biopsies and confocal imaging, comprising an endoscope body 1, a fixing plate 11 on the outer side of the endoscope body 1, an anti-closing component on the fixing plate 11, and a positioning component inside the fixing plate 11. The anti-closing component includes cavities 21 respectively opened on both sides of the fixing plate 11, a rotating shaft 22 connected to the cavity 21, a driving bevel gear 23 fixedly connected to the outer side of the rotating shaft 22, driven bevel gears 24 respectively connected to both sides of the driving bevel gear 23, a lead screw 25 fixedly connected to the driven bevel gear 24, and a drive plate 26 connected to the lead screw 25. The push rod 27 and the outer support plate 28 are fixedly connected to the drive plate 26. The lead screw 25 is rotatably connected to the cavity 21 and screwed to the drive plate 26. The driving bevel gear 23 meshes with the driven bevel gear 24. The rotating shaft 22 is rotatably connected to the fixed plate 11. The fixed plate 11 can be placed inside the mouth. The rotating shaft 22 can drive the driving bevel gear 23 to rotate, which in turn can cause the two driven bevel gears 24 and the lead screw 25 to rotate, thereby driving the drive plate 26 to move the outer support plate 28. The movement of the outer support plate 28 can contact the teeth and hold them in place, preventing the mouth from being injured when the endoscope body 1 is lowered. Under the influence of closure, the endoscope body 1 is inserted into the patient's body. Movable grooves 41 are respectively opened on both sides of the cavity 21. Movable blocks 42 are slidably connected within the movable grooves 41. Movable blocks 42 are fixedly connected to the drive plate 26. The drive plate 26 can drive the movable blocks 42 to move synchronously. The movable blocks 42 can guide the movement of the drive plate 26, preventing the drive plate 26 from rotating synchronously with the lead screw 25, thus acting as a stop for rotation. A rotating plate 51 is fixedly connected to one end of the rotating shaft 22, and a handle 52 is fixedly connected to the other end of the rotating plate 51. The handle 52 facilitates the rotation of the rotating plate 51, thereby facilitating the rotation of the rotating shaft 22 and the active bevel gear. The rotation of wheel 23 facilitates the movement of the outer support plate 28. A protective pad 71 is provided on the outside of the outer support plate 28. The protective pad 71 is fixedly connected to the outer support plate 28 by Velcro. The protective pad 71 can act as a buffer to protect the patient. At the same time, the protective pad 71 can be quickly replaced to prevent cross-infection. The endoscope body 1 has at least two channels 81. One channel 81 is equipped with a biopsy forceps 82 for biopsy. The other channel is equipped with a confocal probe catheter for confocal microscopy imaging. Other channels 81 can facilitate the passage of irrigation devices, etc., for patient treatment.

[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5The positioning component includes an opening 31 on the top of the fixed plate 11, pressure grooves 32 on both sides of the opening 31, a pressure rod 33 in the pressure groove 32, a positioning plate 34 fixedly connected to one end of the pressure rod 33, and a spring 35 sleeved on the outside of the pressure rod 33. The pressure rod 33 is slidably connected to the pressure groove 32. The positioning plate 34 is arc-shaped. The two ends of the spring 35 are fixedly connected to the positioning plate 34 and the inner wall of the opening 31, respectively. The movement of the positioning plate 34 can drive the pressure rod 33 to move, and at the same time, it can compress the spring 35 to deform it. The pressure rod 33 can prevent the spring 35 from tilting. The thrust generated by the deformation of the spring 35 can push the positioning plate 34 to move. The movement of the two positioning plates 34 can clamp and fix the endoscope body 1, preventing the endoscope body 1 from moving. The inner wall of the pressure groove 32 is provided with a toggle groove 61. A toggle plate 62 is fixedly connected to the pressure rod 33. The toggle plate 62 is slidably connected to the toggle groove 61. The toggle plate 62 can drive the pressure rod 33 to move, thereby controlling the movement of the positioning plate 34, which is convenient for fixing or releasing the endoscope body 1.

[0025] Working principle: During operation, the fixed plate 11 is placed inside the mouth. By rotating the handle 52, the handle 52 drives the rotating plate 51 to rotate, which in turn drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the driving bevel gear 23 to rotate, which in turn drives the two driven bevel gears 24 to rotate. The driven bevel gears 24 drive the lead screw 25 to rotate, which in turn drives the drive plate 26 to move, which in turn drives the push rod 27 and the outer support plate 28 to move. The outer support plate 28 causes the protective pad 71 to contact the teeth, thus opening the mouth and allowing the mouth to open. The actuating plate 62 can move the pressure rod 33, which in turn moves the positioning plate 34. The movement of the positioning plate 34 can compress the spring 35, causing it to deform. Then, the endoscope body 1 is lowered into the patient's body. Once it is in the appropriate position, the actuating plate 62 is released. At this time, the thrust generated by the deformation of the spring 35 can push the positioning plate 34 to position and fix the endoscope body 1, preventing the endoscope body 1 from shifting and ensuring the stability of the examination. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
