PROBE FOR TRANSESOPHAGEAL ECHOCARDIOGRAPHY WITH ERGONOMIC CONTROLS
A connectorized ultrasound probe includes a distal section that is configured for insertion into a patient's body and a proximal section configured to interface the distal section with an ultrasound system. The distal section is easily attachable and detachable from the proximal section using at least one set of connectors. When connected, a user-operated actuator located on the proximal section controls the bending of the distal section, and the ultrasound system sends driving signals to and receives return signals from the ultrasound transducer via the proximal section. The proximal section also has a control bottom ergonomically arranged in relation to the actuator to allow actuation of the actuator and button with one hand.
1 . A handle for an ultrasound probe that has a bendable distal portion, comprising:
a gripping portion configured to be comfortably held in a user's hand while the handle is being used;
a control region positioned distal to the gripping portion, the control region having a top and a bottom;
a first actuator disposed on the top of the control region, and positioned such that when the gripping portion is being held in the user's hand, the first actuator is located just beneath a natural resting place of the user's thumb, wherein the first actuator can be moved back and forth in a proximal-distal direction by the user's thumb, and wherein the first actuator is configured so that (a) actuation of the first actuator causes the distal portion of the ultrasound probe to bend and (b) deactuation of the first actuator causes the distal portion of the probe to unbend; and
a second actuator disposed on the bottom of the control region, and positioned such that when the gripping portion is being held in the user's hand with the first actuator located beneath the user's thumb, the second actuator is located adjacent to a natural resting place of the user's forefinger so that the second actuator can be easily actuated by the user's forefinger, wherein actuation of the second actuator generates a signal that is compatible with a control input of an ultrasound system.
2 . The handle of claim 1 , wherein the second actuator comprises a pushbutton switch.
3 . The handle of claim 2 , wherein the signal initiates capturing of an image.
4 . The handle of claim 1 , wherein the first actuator comprises a lever.
5 . The handle of claim 1 , wherein the first actuator comprises a lever and the second actuator comprises a pushbutton switch.
6 . The handle of claim 5 , wherein the signal initiates capturing of an image.
7 . The handle of claim 1 , wherein the handle attaches to the bendable distal portion with a connectorized connection that provides control over bending of the bendable distal portion.
8 . The handle of claim 1 , wherein the handle attaches to the bendable distal portion with a non-connectorized connection.
9 . A handle for an ultrasound probe that has a bendable distal portion, the handle comprising:
a body;
a first actuator located on a first side of the body and positioned so as to be easily actuatable by a user's thumb when the body is being held in the user's hand, wherein the first actuator is configured so that (a) actuation of the first actuator causes the distal portion of the ultrasound probe to bend and (b) deactuation of the first actuator causes the distal portion of the probe to unbend; and
a second actuator located on a side of the body that is opposite to the first side of the body and positioned so as to be easily actuatable by the user's forefinger when the body is being held in the user's hand and the user's thumb is positioned on the first actuator, wherein actuation of the second actuator generates a signal that is compatible with a control input of an ultrasound system.
10 . The handle of claim 9 , wherein the second actuator comprises a pushbutton switch.
11 . The handle of claim 10 , wherein the signal initiates capturing of an image.
12 . The handle of claim 9 , wherein the first actuator comprises a lever.
13 . The handle of claim 9 , wherein the first actuator comprises a lever and the second actuator comprises a pushbutton switch.
14 . The handle of claim 13 , wherein the signal initiates capturing of an image.
15 . The handle of claim 9 , wherein the handle attaches to the bendable distal portion with a connectorized connection that provides control over bending of the bendable distal portion.
16 . The handle of claim 9 , wherein the handle attaches to the bendable distal portion with a non-connectorized connection.
