A method and system for estimating a 3D pose of an ultrasound probe based on acquired 2D ultrasound images. During surgery, the 3D probe pose is projected to a corresponding 2D location on the 2D laparoscopic image. An ultrasound probe is placed at / near a selected one of the 3D probe poses to acquire a 2D ultrasound image from which an anatomical structure (AS) is detected and used to generate an AS mask (ASM). The 3D probe pose of the ultrasound probe is estimated based on the ASM using an ASM pose mapping model and used to generate an optimal 3D probe pose estimate.

The application discloses a multifunctional surgical dissector, which comprises a hollow shell, an electrode knife head, a PCB board, a high-frequency electrotome conductive sheet, an ultrasonic input conductive sheet, an ultrasonic output conductive sheet, a function switching knob and an ultrasonic transducer. The function switching knob is rotated to control the conduction route. When the function switching knob is rotated to the high-frequency electrotome conductive sheet and the ultrasonic input conductive sheet and the ultrasonic output conductive sheet are all conducted, the electrode knife head can have high-efficiency cutting of the high-frequency electrotome, and can significantly reduce tissue adhesion and thermal damage by using the vibration characteristics of the ultrasonic surgical knife, thereby improving the operation efficiency. When the function switching knob is rotated to only connect the high-frequency electrotome conductive sheet, the device can be used as a high-frequency electrotome alone. When the function switching knob is rotated to only connect the ultrasonic input conductive sheet and the ultrasonic output conductive sheet, the device can be used as an ultrasonic surgical knife alone, so that the device has multiple functions and is suitable for various surgical environments.
