Embodiment Construction

[0053] The following examples are only used to illustrate the present application and should not be considered as limiting the scope of the present application. Those who do not indicate the specific conditions in the examples are carried out according to the conventional conditions or the conditions suggested by the manufacturer. The reagents or instruments used were not indicated by the manufacturer, and they were all conventional products that could be purchased from the market.

[0054] The invention aims at the problems of lack of real-time positioning and navigation equipment in uretero-renal interventional operations and difficult manipulation of flexible ureteroscopes. With the development of flexible ureteroscopy technology in recent years, it has become an important method of minimally invasive diagnosis and treatment in urology, gradually replacing traditional percutaneous renal invasive surgery. Only in our country, millions of people carry out minimally invasive ...

Abstract

The invention relates to the technical field of medical instruments, in particular to a flexible ureteroscope with a magnetic positioning function and a ureteroscope pose estimation system. The flexible ureteroscope comprises a ureteroscope tube which comprises a tip part, a bending part and an insertion part which are connected in sequence; the tip part is provided with a first magnetic positioning sensor which is used for detecting a first magnetic positioning signal and transmitting the first magnetic positioning signal to a navigation system server; the illumination light transmitting bundle penetrates through the endoscope tube, one end of the illumination light transmitting bundle is connected with a light source, and the other end of the illumination light transmitting bundle is close to or located at the tip part, so that illumination light emitted by the light source is transmitted to the tip part; the tip part is provided with a camera module, and the camera module is used for capturing a first image under the action of light transmitted by the illumination light transmitting bundle and transmitting the first image to the navigation system server, so that the navigation system server displays the first image through an image display.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a flexible ureteroscope with a magnetic positioning function and a pose estimation system for the ureteroscope. Background technique [0002] In uretero-renal interventional surgery, manipulating the flexible ureteroscope requires extensive experience. The patient's calices structure is complicated with multiple pipeline branches, and even the vision is not clear due to hematuria, and there is a lack of equipment for real-time positioning of the tip of the endoscope and detection of the posture of the operating part during the operation. Novice doctors tend to get lost when manipulating the flexible ureteroscope, do not know the position and shape of the intrarenal pipeline, and even get stuck in the position, resulting in the inability to explore deeply and find stones or tumors. In addition, intrarenal intrarenal pressure is likely to be excessive due to cont...
