초록 ▼

An adjustable profile probe for insertion in a body cavity to sense a biological parameter includes an elongated shaft having a sensor panel and a resiliently expandable portion substantially opposing the sensor panel. An expansion mechanism is at least partially housed within the elongated shaft for varying the profile of the probe. The expansion mechanism includes a base plate adjacent to the resiliently expandable portion and a plurality of lever arms pivotally mounted to the base plate and the sensor panel. An actuating member pivotally connects to the lever arms such that upon movement of the actuating member, the resiliently expandable portion is selectively collapsed or expanded by the plurality of lever arms pivoting between a minimal profile position near parallel with the elongated shaft and an expanded profile position with the lever arms being near perpendicular to the elongated shaft.

1. A mechanism for varying a profile of an elongated rectal probe having a sensor, comprising: an expandable portion;a plurality of lever arms pivotally mounted to the rectal probe adjacent the expandable portion, the sensor protruding through a rigid sensor panel and mounted to a portion of the rectal probe separate from the expandable portion at a fixed radial distance from a longitudinal axis defined by the elongated rectal probe; anda linkage shaft attached to the plurality of lever arms for moving the arms from a first position in which the expandable portion is relaxed and a second position in which the expandable portion is extended, the sensor being at the fixed radial distance when the expandable portion is relaxed and when the expandable portion is extended, the rigid sensor panel mounted to the elongated rectal probe by a shoulder configured to raise the profile of the sensor panel with respect to the elongated rectal probe to press the sensor against a wall of an organ when the expandable portion is extended within a body of a patient. 2. The mechanism of claim 1 wherein the expandable portion has a thickness that varies to determine the profile of the elongated rectal probe in the second position. 3. The mechanism of claim 1 further comprising a base plate with at least one of the plurality of lever arms mounted thereto. 4. An adjustable profile probe for insertion in a body cavity to sense a biological parameter, comprising: an elongated shaft defining an interior, the elongated shaft including a proximal end, a closed distal end, a rigid portion, and a resiliently expandable portion substantially opposing the rigid portion;at least one sensor mounted on the rigid portion for generating a signal corresponding to the biological parameter, the at least one sensor protruding through a sensor panel; andan expansion mechanism at least partially housed within the interior, the expansion mechanism separate from the rigid portion, the expansion mechanism including: a base plate adjacent to the resiliently expandable portion;a plurality of lever arms including a first end pivotally mounted to the base plate and a second end adjacent to the rigid portion; andan actuating member pivotally connected to the plurality of lever arms and extending toward the proximal end such that, upon movement of the actuating member towards the closed distal end, the resiliently expandable portion expands and, upon movement towards the proximal end, the resiliently expandable portion is allowed to collapse, the at least one sensor being disposed at a fixed radial distance from a longitudinal axis defined by the elongated shaft when the expandable portion both expands and collapses, the sensor panel mounted to the elongated shaft by a shoulder configured to raise the profile of the rigid sensor panel with respect to the elongated shaft to press the sensor against a wall of an organ when the expandable portion is expanded within a body of a patient. 5. The probe of claim 4 wherein the at least one sensor is fixedly mounted relative to the elongated shaft. 6. The probe of claim 4 wherein the actuating member includes a plurality of bar links. 7. The probe of claim 4 wherein the resiliently expandable portion is fabricated from a material selected from the group consisting of silicone, latex, nitrile rubber, and combinations thereof. 8. The probe of claim 7 wherein the resiliently expandable portion has a varying thickness. 9. The probe of claim 4 wherein at least one of the plurality of lever arms is pivotally mounted to the rigid portion. 10. The probe of claim 4 wherein the rigid portion is near the closed distal end. 11. The probe of claim 4 wherein the rigid portion is on the closed distal end. 12. The probe of claim 4 wherein the sensor panel includes a plurality of sensors. 13. A mechanism for varying a profile of a probe, comprising: an expandable portion;a plurality of lever arms pivotally mounted to the probe adjacent the expandable portion;at least one temperature sensor protruding through a rigid sensor panel; andmeans attached to the plurality of lever arms for moving the plurality of lever arms between:(a) a first position where the profile of the probe is substantially minimized, the rigid sensor panel located at a radial distance from a longitudinal axis of the probe when the lever arms are in the first position; and(b) a second position where the at least one arm presses the expandable portion and thereby enlarges the profile of the probe, the rigid sensor panel located at the same radial distance from the longitudinal axis of the probe when the lever arms are in the second position as when the lever arms are in the first position, the rigid sensor panel mounted to the probe by a shoulder configured to raise the profile of the sensor panel with respect to the probe to press the at least one sensor against a wall of an organ when the expandable portion is enlarged within a body of a patient. 14. The mechanism of claim 13 wherein the expandable portion is substantially opposing the rigid sensor panel. 15. The mechanism of claim 13 further comprising a base plate with at least one of the plurality of lever arms pivotally coupled thereto. 16. The mechanism of claim 13 wherein the means is at least one bar link. 17. The mechanism of claim 13 wherein the means is a screw drive actuator.
