First Claim
1. An ultrasound probe with a needle guide passage for a puncture needle, said ultrasound probe comprising:
- an ultrasound transducer mounted on a girder portion of a rigid fore end section at the distal end of a flexible insert section of a catheter member of said ultrasound probe; and
a needle passage provided axially within said catheter member of said ultrasound probe for launching a puncture needle therethrough, said needle passage being turned toward an exit opened on a lateral side portion of said rigid fore end section at a position on the near side of said ultrasound transducer; and

Abstract
An ultrasound probe with a needle guide passage for a puncture needle, the ultrasound probe having an ultrasound transducer mounted on a girder portion of a rigid fore end section at the distal end of a flexible insert section of a catheter member to be introduced into an intracavitary portion, and a needle passage provided axially within the catheter member for launching the puncture needle therethrough. The needle passage is turned toward an exit opened on a lateral side portion of the rigid fore end section at a position on the near side of the ultrasound transducer. The rigid fore end section of the catheter member is provided with a bent portion which is turned off the axis of the catheter member through a predetermined angle in a direction away from a needle launching direction of the needle passage at a position on the near side of the exit opening of the needle passage.
