Background
Hysteroscopes are used for examination and treatment in the uterine cavity. When the hysteroscope is used, the lens of the hysteroscope can magnify and observe the part in the uterine cavity. The surgical instrument can perform surgical operation on the uterine cavity through the hysteroscope. From the inspection perspective, hysteroscopes are the first-choice inspection instruments for gynecological hemorrhagic diseases and intrauterine lesions.
The hysteroscope should be rotatable to increase the overall field of view for a complete examination of the uterus. When the hysteroscope is used, the horizontal line of the camera can rotate relative to the anatomical structure of the patient when the camera at the front end of the hysteroscope is rotated. In order to compensate for this, the rotation angle is recorded by rotating the gear structure and the potentiometer on the operating part of the hysteroscope, and the embedded software in the image signal processing board reads the signal and compensates accordingly.
And the visual angle (DOV) of the hysteroscope should be inclined to meet the clinical requirements, and the DOV should be 0 degrees, 12 degrees and 20 degrees to 30 degrees to meet different program requirements. Most conventional hysteroscopes meet the requirements of various viewing angles by tilting the tip or implementing a prismatic structure. If the prism is added, the manufacturing cost is increased, and how to position the prism in the production is also a technical problem, which makes the production and the manufacturing difficult. In addition, the hysteroscope front end is a beveled tip, which makes it relatively difficult to insert the tip into the cervix of the uterus, and may damage the tip during insertion.

Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1 to 5. It should be understood that the structures, ratios, sizes, etc. shown in the drawings of the present specification are only used for matching with the contents disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any modification of the structures, changes of the ratio relationship, or adjustment of the sizes should still fall within the scope covered by the technical contents disclosed in the present invention without affecting the efficacy and the achievable purpose of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
The utility model relates to a hysteroscope, the core of this embodiment is the imaging module on the hysteroscope, and the front end of intubate carries camera etc. in the hysteroscope is arranged in to it, is used for acquireing the internal image of human body when the diagnosis.
As shown in fig. 1 to 5, the imaging module of the present embodiment includes:
the supporting seat 1 is provided with an instrument through channel 2 and three mounting grooves 12 which are arranged at the end part of the supporting seat and distributed annularly, wherein an inclined surface 11 is arranged in the mounting groove 12 in the middle, and the inclined surface 11 and the axis L of the instrument through channel 2 form an acute angle;
the camera 3 is arranged in the mounting groove positioned in the middle and is fixed on the inclined surface 11;
