More Information
Summary:A medical endosurgical device is provided having both ultrasonic imaging and biopsy capabilities for easy grasping and manipulation by a surgeon. The medical endosurgical apparatus includes an ultrasonic imaging probe having an insertion portion with an ultrasonic device near the insertion tip and a probe handle for manipulating the ultrasonic imaging probe to position the ultrasonic device in the patient's body. The medical endosurgical device also includes a biopsy actuator that is mounted on the handle of the ultrasonic imaging probe so that a biopsy needle assembly exiting from the biopsy actuator is oriented to the field of view of the ultrasonic device on the probe. The medical endosurgical apparatus may also include a rigid sheath disposed over the insertion portion of the ultrasonic imaging probe that is engaged with and oriented to the ultrasonic imaging probe such that a biopsy needle assembly passing through a lumen in the rigid sheath would be oriented to the field of view of the ultrasonic device.
