AI Technical Summary

Technical Problem

Current hysteroscopic surgeries require different methods and/or instruments, depending on the type of surgery, the patient's anatomy, and technical considerations. Furthermore, switching between different imaging modalities requires changing instruments, leading to complex operations and low efficiency.

Method used

A hysteroscopy system is provided that combines an ultrasound device and a hysteroscope. The ultrasound device includes a removable shaft and an ultrasound sensor assembly for ultrasound imaging, and the hysteroscope is used for visualization. The system allows for flexible insertion and fixation of the instruments through a movable sheath and a locking mechanism, and supports multimodal imaging and operation.

Benefits of technology

It enables switching imaging modes during hysteroscopy without changing instruments, improving the flexibility and efficiency of the surgery and providing multi-angle imaging and manipulation capabilities of the uterus and surrounding tissues.

Abstract

An ultrasound device includes a frame and an ultrasound sensor assembly. The frame includes first and second rails spaced apart relative to each other and a longitudinal segment defining a longitudinal axis. The longitudinal segment has a distal end portion. The ultrasound sensor assembly is configured to enable ultrasound imaging of a field of view and is attached to the distal end portion of the longitudinal segment of the frame and is oriented such that the field of view is disposed at an oblique angle relative to the longitudinal axis. A surgical system is also provided that includes the ultrasound device and a surgical instrument insertable through the ultrasound device.
