Ultrasound guided probe device and sterilizable shield for same

摘要

Disclosed are medical probe devices and methods for use guiding of percutaneous probes during medical procedures. The probe devices include an ultrasound transducer housing having a passage therethrough configured to accommodate a probe. The devices can be utilized to guide a probe through the probe guide to a percutaneous target with real time visualization of the probe during the procedure. In addition, the devices can include a sterilizable shield including a sterile probe guide such that the transducer housing itself can be separated from a subject by a sterile barrier. The sterilizable shield can be a single-use shield that can prevent contamination and re-use of the shield. The devices can define a beneficial geometry conducive to use by a single operator that can be utilized for percutaneous targets near the skin surface and can enable excellent contact between the device and the skin surface of a subject.

主权项

1. A medical probe device comprising:
a monitor; a housing comprising an ultrasound transducer for forming a sonogram of a subdermal location on the monitor, the housing including a skin contacting surface; a probe guide that is attachable to the housing; a detector for detecting motion of a probe within the probe guide, the detector including a magnetic motion detection mechanism to generate signals regarding the movement of a probe as it passes through the probe guide, the signals from the detector creating a data stream; a processor in communication with the detector, the monitor, and the ultrasound transducer, the processer configured for creating and displaying a real time image of a virtual probe, the processor being programmed to analyze the data stream from the detector to calculate a relative position of the probe in relation to a reference point, the processor being capable of communicating the relative position to the monitor, said relative position being displayed on the monitor as the real time image of the virtual probe; and the processor being further configured for displaying on the monitor the real time image of the virtual probe in conjunction with the sonogram of the subdermal location.
