Abstract

An ultrasound probe and a ultrasound system are disclosed. In some embodiments, the ultrasound system includes a bite block configured to, during a transesophageal insertion of the probe cable starting from the distal end, guard the probe cable from a bite and prevent anteflexion and retroflexion movement of the transducer until a predetermined length of the probe cable is inserted.

First claim

We claim:

1. A transesophageal ultrasound system comprising:
a transesophageal ultrasound probe including a probe body, a probe cable, and a transducer, the probe body detachably connected to a one end of the probe cable and the transducer connected to a distal end of the probe cable; and
a bite block configured to, during transesophageal insertion of the probe cable starting from the distal end, guard the probe cable from a bite and prevent anteflexion and retroflexion movement of the transducer until a predetermined length of the probe cable is inserted, wherein the bite block is implemented to, during transesophageal removal of the probe cable, prevent the anteflexion and retroflexion movement of the transducer by configuring the transducer in a limp state until an additional predetermined length of the probe cable is removed.

2. The transesophageal ultrasound system as described in claim 1 , wherein the probe body is implemented to be disconnected from the probe cable while the transducer and a portion of the probe cable remain transesophageally inserted.

3. The transesophageal ultrasound system as described in claim 2 , wherein the probe body, once said disconnected from the probe cable, is configured to be detachably connected to an additional probe cable.

4. The transesophageal ultrasound system as described in claim 3 , wherein the additional probe cable is of a different length than the probe cable or is connected to an additional transducer that is of a different diameter or head size than the transducer.

5. The transesophageal ultrasound system as described in claim 1 , further comprising an ultrasound machine communicatively coupled to the transesophageal ultrasound probe, the ultrasound machine including a user interface configured to display an indicator of a flexion angle corresponding to the anteflexion and retroflexion movement of the transducer.

6. The transesophageal ultrasound system as described in claim 1 , further comprising a hand-worn radiator configured to be placed on a patient location and control the anteflexion and retroflexion movement of the transducer so that the transducer directs ultrasound in a direction based on the patient location.

7. A transesophageal ultrasound system comprising:
a transesophageal ultrasound probe including a probe body, a probe cable, and a transducer, the probe body detachably connected to a one end of the probe cable and the transducer connected to a distal end of the probe cable;
a bite block configured to, during transesophageal insertion of the probe cable starting from the distal end, guard the probe cable from a bite and prevent anteflexion and retroflexion movement of the transducer until a predetermined length of the probe cable is inserted; and
a hand-worn radiator configured to be placed on a patient location and control the anteflexion and retroflexion movement of the transducer so that the transducer directs ultrasound in a direction based on the patient location.

8. The transesophageal ultrasound system as described in claim 7 , wherein the probe body is implemented to be disconnected from the probe cable while the transducer and a portion of the probe cable remain transesophageally inserted.

9. The transesophageal ultrasound system as described in claim 8 , wherein the probe body, once said disconnected from the probe cable, is configured to be detachably connected to an additional probe cable.

10. The transesophageal ultrasound system as described in claim 9 , wherein the additional probe cable is of a different length than the probe cable or is connected to an additional transducer that is of a different diameter or head size than the transducer.

11. The transesophageal ultrasound system as described in claim 7 , further comprising an ultrasound machine communicatively coupled to the transesophageal ultrasound probe, the ultrasound machine including a user interface configured to display an indicator of a flexion angle corresponding to the anteflexion and retroflexion movement of the transducer.

12. The transesophageal ultrasound system as described in claim 7 , wherein the bite block is implemented to, during transesophageal removal of the probe cable, prevent the anteflexion and retroflexion movement of the transducer.
