[0029] Example:

[0030] Figure 1 It is a hysteroscope used to collect specimens. Figure 2 yes Figure 1The front view of the image shows only the structure relevant to this application; other components such as the control unit are not shown. The structure includes a housing 1, a moving cylinder 2, a mirror body 3, and a camera 4. The housing 1, the moving cylinder 2, and the mirror body 3 are coaxially arranged from the outside in. The camera 4 is located at the front end of the mirror body 3. A receiving plate 21 is provided at the front end of the moving cylinder 2. The receiving plate 21 can be completely retracted into the cavity of the housing 1 or extended forward to the outside of the housing 1. A control component is provided at the rear end of the moving cylinder 2 to control its forward and backward movement.

[0031] This invention features a movable cylinder between the outer shell and the endoscope body. The front end of the movable cylinder is equipped with a receiving plate, which can extend to catch the specimen, then retract and leave the patient's body along with the hysteroscope. This facilitates immediate catching of the uterine specimen during cutting, making it easy to remove and convenient to use.

[0032] Figure 3 This is a schematic diagram of the moving cylinder. Figure 4 yes Figure 3 A partially enlarged schematic diagram shows that the front end face of the movable cylinder 2 has an upper notch to form the receiving plate 21. The receiving plate 21 is arc-shaped and has filter holes 22 to form a filter plate structure.

[0033] The receiving plate of this invention is arc-shaped, meaning that a section of the outer shell of the moving cylinder is directly used as the receiving plate. The arc-shaped structure facilitates the loading of specimens, and since the specimen volume is very small, the arc-shaped plate of the moving cylinder is sufficient to hold the specimen. The receiving plate is also equipped with filter holes to filter out liquids such as swelling fluid, achieving solid-liquid separation.

[0034] The front end of the receiving plate 21 has a baffle 23, and the height of the baffle 23 is lower than the height of the receiving plate 21.

[0035] This utility model features a baffle to prevent the specimen from falling due to inertia when retracting with the specimen. For ease of understanding, Figure 4 In the middle, 'h' represents the height difference.

[0036] Figure 5 This is a schematic diagram of the mirror body. The front end of the mirror body 3 has a bottom notch 31, and the baffle 23 is located in the bottom notch 31.

[0037] The baffle of the microscope body and the receiving plate of this utility model are combined to hold a part of the space of the microscope body and increase the space of the receiving plate, which makes it easier to load specimens.

[0038] Combined with the diagram Figure 3 and Figure 6 The control component comprises a rod and a groove. The rod is fixed to the rear end surface of the movable cylinder 2, and the groove is opened at the rear end of the outer shell 1. The rod is placed in the groove.

[0039] like Figure 3 As shown, the rod includes a guide rod 24 and a handheld rod 25. The guide rod 24 is fixed to the rear end surface of the movable cylinder 2 along the length direction, and the handheld rod 25 is fixed to the rear end of the guide rod 24.

[0040] like Figure 6 As shown, the groove includes a guide groove 13 and a limiting groove 12. The guide groove 13 is connected to the limiting groove 12. The guide rod 24 is disposed in the guide groove 13 and moves along the guide groove 13. The handheld rod 25 is disposed in the limiting groove 12 and moves along the limiting groove 12. The length of the guide groove 13 is greater than the length of the limiting groove 12.

[0041] like Figure 7 The image shown is a rear view of the casing, as follows: Figure 8 What is shown is Figure 1 The diagram illustrates the extended state of the movable tube. Medical personnel grasp the handle 25 and push it forward. Under the action of the guide rod and guide groove, the movable tube moves forward, causing the receiving plate 21 to extend. The front wall of the limiting groove 12 acts as a limit. At this point, the receiving plate is fully extended. After catching the specimen, the handle 25 can be grasped and pulled back to allow the receiving plate to retract completely into the outer shell 1. Alternatively, a rear limiter can be installed on the endoscope body 3 to prevent the movable tube from overextending later.

[0042] like Figure 6 As shown, a receiving groove 11 is also provided at the lower front end of the outer shell 1, which can catch liquids such as distending fluid dripping from the specimen after the moving cylinder retracts.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
