[0002] Based on existing technology, a digital hysteroscope is a device used for intrauterine examination and treatment. During use, the camera of the digital hysteroscope allows for observation of the uterine cavity. Furthermore, surgical instruments inserted into the digital hysteroscope allow for surgical procedures within the patient's uterine cavity. Due to its convenient examination, the digital hysteroscope is the preferred diagnostic tool for gynecological bleeding disorders and intrauterine pathologies.
[0003] However, the working length of current electronic hysteroscopes is fixed and cannot be changed during use. Therefore, when a patient's condition is unique, the range of compatible instruments is limited by the hysteroscope's working length, making effective adaptation impossible. To meet these specific needs, custom instruments of specific lengths are often required for auxiliary use, which is very inconvenient.

[0032] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0033] like Figures 1 to 3The variable-length electronic hysteroscope comprises a hysteroscope body 1. Its unique features include: a decompression chamber 1 is provided with a water tank assembly at the front of the decompression chamber. To achieve length adjustment and ensure proper watertightness, the decompression chamber is provided with an adjustment housing 2, and a length adjustment handle 3 is movably provided at the rear end of the adjustment housing 2. Furthermore, to ensure proper positioning of the hysteroscope after length adjustment during use, a temporary limiting mechanism is provided on the inner side of the adjustment housing 2, and an adjustment mechanism that cooperates with the temporary limiting mechanism is provided at the front end of the length adjustment handle 3, with the temporary limiting mechanism in contact with the adjustment mechanism. Thus, after length adjustment is completed, the hysteroscope can be properly locked, preventing secondary telescopic displacement. Furthermore, the present invention provides a stop mechanism at the front end of the length adjustment handle 3, and a terminal limiting mechanism is provided on the inner side of the adjustment housing 2. When the length adjustment handle 3 is in its longest outward position, the terminal limiting mechanism abuts against the stop mechanism. This prevents the length adjustment handle 3 from being accidentally pulled out when in its longest position.
[0034] In view of a preferred embodiment of the present invention, the temporary limiting mechanism includes a contact surface located on the inner wall of the rear side of the adjustment housing 2, and the contact surface is provided with a protrusion structure 4 distributed inward. Correspondingly, the adjustment mechanism is a plurality of spaced limiting grooves 5. In this way, when in the locked state, the protrusion structure 4 is embedded in the corresponding limiting groove 5. Specifically, in order to achieve appropriate contact limiting, the protrusion structure 4 is a convex strip or a bump. Thus, when in the locked state, the protrusion structure 4 is interference fit with the limiting groove 5. In this way, other external stresses during use will not cause the protrusion structure 4 to be easily separated from the limiting groove 5, and it has better stability in use. In addition, the present invention is provided with a guide flare 8 at the upper end of the limiting groove 5, which can realize the insertion and sliding guidance of the protrusion structure 4 under the premise of reasonable force application. In this way, when the user holds the length adjustment handle 3 to apply force, there is an appropriate adjustment damping feeling and no jamming occurs.
[0035] Furthermore, the stop mechanism is a stop boss 6, and the terminal stop mechanism is a contact step 7. During use, when the length adjustment handle 3 is in its longest extended position, the inner edge of the stop boss 6 abuts the outer edge of the contact step 7. This effectively stops the handle 3, preventing the user from pulling out the length adjustment handle 3 due to improper force at the maximum length. Furthermore, a marking can be provided at the maximum adjustable position of the length adjustment handle 3 to remind the user that this position has been reached, thus preventing improper secondary force application.
[0036] In view of actual implementation, in order to achieve proper movement guidance, a stop guide column 9 is provided at the rear end of the inner side of the adjustment shell 2, and a through channel is distributed in the stop guide column 9 to facilitate the subsequent installation guidance of the steel pipe 13. At the same time, an adjustment guide groove 10 is provided at the front end of the length adjustment handle 3, and the stop guide column 9 is inserted into the adjustment guide groove 10. When at the shortest limit distance, the front end of the stop guide column 9 contacts the inner bottom of the adjustment guide groove 10. In this way, the length adjustment handle 3 can be prevented from causing improper squeezing of the decompression chamber. Of course, in order to have a proper buffering contact effect, the utility model is provided with a buffer pad at the front end of the stop guide column 9.
[0037] Looking further, the length adjustment handle 3 is equipped with a gripping mechanism 11, which consists of a plurality of arcuate grooves. Alternatively, the gripping mechanism 11 can be formed using a plurality of ridges arranged in an array. This provides a superior non-slip grip and facilitates length adjustment. Furthermore, to facilitate the subsequent installation and guidance of the steel tube 13, a connecting channel 12 is provided within the length adjustment handle 3 for guiding the steel tube 13.
[0038] The working principle of this utility model is as follows:
[0039] In the default state, the length adjustment handle 3 is in the shortest length state of extreme compression. During use, when the user needs to adjust the current image viewing distance, the length adjustment handle 3 can be held and stretched appropriately. After the length adjustment handle 3 is limited by the temporary limiting mechanism and the adjustment mechanism, a "click" sound can be heard due to the deformation of the material, indicating that the temporary limiting mechanism and the adjustment mechanism are in a temporarily locked state. The user can further perform corresponding operations, through the steel pipe 13 attached to the hysteroscope body 1, so that the head end bracket attached thereto drives the camera to the specified position.
[0040] During use, when the user grips the length adjustment handle 3 and pulls it outward to the maximum length, the stop mechanism and the terminal limit mechanism cooperate to prevent the length adjustment handle 3 from abnormally separating. At the same time, when in the maximum position, the user can visually observe a marking, such as a red line, set at the longest adjustable position of the length adjustment handle 3, to avoid improper secondary force application.
[0041] It can be seen from the above text description and the accompanying drawings that the present invention has the following advantages:
[0042] 1. The length of the decompression chamber can be adjusted by adjusting the length of the handle, which can drive the steel pipe inside to different positions, providing better extreme image observation distance and operating space. It does not require additional auxiliary equipment and is safe and convenient to use.
[0043] 2. Relying on the cooperation of the temporary limiting mechanism and the adjusting mechanism, the length adjustment handle can be temporarily positioned. Since the current length is limited, improper retraction will not occur during use. The user does not need to always hold the length adjustment handle to limit the position, which improves the convenience of operation.
[0044] 3. It is equipped with a stop mechanism and a terminal limit mechanism, which can effectively prevent the length adjustment handle from being accidentally pulled out and has better stability in use.
[0045] 4. The overall structure is simple, and the existing hysteroscope body can be replaced and modified, with low implementation cost and good versatility.
[0046] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated in a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
