Abstract

A scope system includes a processor and a scope device. The scope device includes a handle configured to remain outside of the body and an elongated shaft extending from the handle to a distal tip and including a working channel extending therethrough. The working channel is open at the distal tip of the shaft. The shaft is inserted through a bodily lumen to a target surgical site. The shaft includes at least one sensor transmitting to the processor sensor data relating to the target surgical site.

First claim

What is claimed is:

1. A scope system, comprising:
a processor; and
a single-use scope device, comprising:
a handle configured to remain outside of a body; and
an elongated shaft extending from the handle to a distal tip and including a working channel extending therethrough, the working channel being open at the distal tip of the shaft and adjacent to a camera and a light source, the shaft being configured to be inserted through a bodily lumen to a target surgical site, the shaft including a pressure sensor embedded in a housing mounted within the distal tip of the shaft, the pressure sensor being configured to measure intraluminal pressure relating to a target surgical site and to transmit to the processor sensor data relating to the target surgical site, an active portion of the pressure sensor being adjacent a window of the housing and proximate a surface of a diameter of the shaft, wherein the active portion is covered by a water-tight coating within the window that separates the active portion of the pressure sensor from fluid surrounding the scope device while permitting the active portion of the pressure sensor to measure pressure in the fluid surrounding the scope device.

2. The system of claim 1 , wherein the pressure sensor is a chip pressure sensor which measures a pressure exerted by the target surgical site on the chip pressure sensor.

3. The system of claim 1 , wherein the scope device further includes a temperature sensor positioned at a distal surface of the distal tip and providing a temperature readout from the distal tip to the processor.

4. The system of claim 1 , wherein the scope device further includes a force sensor configured to measure external forces exerted on tissue by the shaft, the force sensor being positioned on an outer circumference of the shaft and including a wire that extends through the shaft to connect to the processor.

5. The system of claim 1 , wherein the scope device includes a series of force sensors placed along a length of the shaft, the force sensors measuring a ureteral peristalsis wave force.

6. The system of claim 1 , further comprising a fluid source coupled to the scope device, the fluid source providing fluid through the shaft to the target surgical site.

7. The system of claim 1 , wherein the processor includes a display screen and a user interface, the display screen displaying the sensor data to a user, and wherein the processor stores a maximum pressure and is configured to trigger an alarm when the pressure sensor measures the maximum pressure.

8. The system of claim 1 , wherein the scope device further includes a gyroscope sensor to measure an angular rate of the elongated shaft as it deflects within the target surgical site.

9. The system of claim 1 , wherein the scope device further includes a pH sensor.

10. The system of claim 1 , wherein the housing is rectangular.

11. The system of claim 10 , wherein the window is on a long side of the housing, and wherein a shape of the window is a square.

12. The system of claim 1 , wherein the pressure sensor provides the sensor data to the processor by a lead coupled to the pressure sensor and extending through the shaft, and wherein portions of the lead are within the housing.

13. The system of claim 1 , wherein the pressure sensor is below the window of the housing and proximate a surface of the shaft.

14. A scope system, comprising:
a processor; and
a single-use scope device, comprising:
a handle configured to remain outside of a body; and
an elongated shaft extending from the handle to a distal tip and including a working channel extending therethrough, the working channel being open at the distal tip of the shaft, the shaft being configured to be inserted through a bodily lumen to a target surgical site, the shaft including first and second sensors transmitting to the processor first and second sensor data, respectively;

wherein the first sensor is a pressure sensor embedded in a housing mounted within the distal tip of the shaft, an active portion of the pressure sensor being adjacent to a window of the housing and below a surface of the shaft, the active portion being covered by a water-tight coating that separates the active portion of the pressure sensor from fluid surrounding the scope device while permitting the active portion of the pressure sensor to measure pressure in the fluid surrounding the scope device, the scope device being configured for use in one of ureteroscopy, hysteroscopy, bronchoscopy, or cystoscopy.

15. The system of claim 14 , wherein the second sensor is one of a temperature sensor, a pH sensor, a capacitive sensor, or a gyroscope sensor.

16. The system of claim 14 , further comprising a fluid source coupled to the scope device, the fluid source providing fluid through the handle and the shaft to the target surgical site.

17. The system of claim 14 , wherein the processor includes a display screen and a user interface, the display screen displaying the first and second sensor data to a user.

18. The system of claim 14 , wherein the pressure sensor is coupled to a lead that extends through the shaft.

19. The system of claim 14 , wherein the housing is rectangular.
