Ultrasound device and ultrasound imaging method

An ultrasound device, comprising:

• an ultrasound probe, configured to perform transmission of ultrasound waves and reception of ultrasound echo signals;
• a guidance member, comprising a guide body and a distal portion, wherein the ultrasound probe is disposed at the distal portion, and the guide body is configured to guide the ultrasound probe at the distal portion into a patient's body cavity;
• a drive mechanism, configured to drive the ultrasound probe to move within the body cavity;
• one first function key, capable of being triggered in a first type by an operator to execute a disengagement function;
• and
• a controller;
• wherein:
• when the ultrasound probe is guided into the body cavity and in a contact state with a biological tissue that forms the body cavity, the ultrasound probe performs the transmission of ultrasound waves and the reception of ultrasound echoes to obtain the ultrasound echo signals that are used to generate an ultrasound image;
• and
• when the first function key is triggered in the first type, the controller is configured to control execution of the disengagement function, wherein the disengagement function comprises the controller controlling the drive mechanism to drive the ultrasound probe to perform a disengagement motion, so as to transition from the contact state to a non-contact state with the biological tissue.

An ultrasound imaging method, comprising:

• controlling an ultrasound probe to perform transmission of ultrasound waves and reception of ultrasound echoes to obtain ultrasound echo signals that are used to generate an ultrasound image, wherein the ultrasound probe is guided into a patient's body cavity and is in a contact state with a biological tissue that forms the body cavity;
• and
• controlling execution of a first function and a disengagement function when a first function key is triggered, wherein the first function is different from the disengagement function,
• wherein the disengagement function comprises:
• controlling the ultrasound probe to perform a disengagement motion so as to transition from the contact state to a non-contact state with the biological tissue.
