Endoscopic imaging and control systems and methods for use in diagnostic and therapeutic medical procedures
Endoscopic viewing systems for use in diagnostic and therapeutic medical procedures. More specifically, an imaging and control system and coupler that allows for control of imaging and fluid management from a hand-held unit coupled to a conventional multiple-use, sterilizable endoscope.
1. An endoscopic system comprising:
a handle with a rotatable C-mount coupler assembly for coupling to a proximal end of an endoscope;
an image sensor carried by the rotatable C-mount coupler assembly;
at least one of an accelerometer and a gyroscope carried by the rotatable C-mount coupler assembly; and
electrical leads extending from the at least one accelerometer and gyroscope to a fixed location in the handle, wherein the electrical leads are configured with a slack portion in an interior of the handle to accommodate rotation of rotation of the rotatable C-mount coupler assembly therein.
2. The endoscopic system of claim 1 further comprising:
a controller and an image processor coupled to the image sensor and the at least one accelerometer and gyroscope; and
a controller algorithm adapted to acquire signals from the at least one accelerometer and gyroscope caused by rotation of the C-mount coupler and thereafter rotate a displayed image in response to the signals to correct an orientation of the displayed image to a selected configuration.
3. The endoscopic system of claim 2 further comprising a fluid management system controlled by the controller, and at least one actuator in the handle for adjusting operating parameters of the fluid management system.
4. The endoscopic system of claim 3 wherein the controller includes algorithms for operating a fluid inflow source and a negative pressure source of the fluid management system to maintain fluid pressure in a working space within a set pressure range.
5. The endoscopic system of claim 1 further comprising electrical leads extending from the image sensor to a fixed location in the handle, wherein the electrical leads are configured with a slack portion in an interior of the handle to accommodate rotation of the rotatable C-mount coupler assembly therein.
6. The endoscopic system of claim 1 wherein the rotatable C-mount coupler assembly is configured to rotate at least 90° about its axis in the handle.
7. The endoscopic system of claim 1 wherein the rotatable C-mount coupler assembly is configured to rotate at least 180° about its axis in the handle.
8. The endoscopic system of claim 1 further comprising a light source adapted for coupling to the endoscope and at least one actuator in the handle for adjusting operating parameters of light source.
9. The endoscopic system of claim 1 further comprising at least one actuator in the handle for operating the image sensor to capture images or videos.
10. An endoscopic system comprising:
a handle with a rotatable C-mount coupler assembly for coupling to a proximal end of an endoscope;
an image sensor carried by the rotatable C-mount coupler assembly;
at least one of an accelerometer and a gyroscope carried by the rotatable C-mount coupler assembly;
a controller and image processor coupled to the image sensor and the at least one accelerometer and gyroscope, wherein a controller algorithm is adapted to acquire signals from the at least one accelerometer and gyroscope caused by rotation of the C-mount coupler and thereafter rotate a displayed image in response to the signals to correct an orientation of the displayed image to a selected configuration; and
electrical leads extending from the at least one accelerometer and gyroscope to a fixed location in the handle, wherein the electrical leads are configured with a slack portion in an interior of the handle to accommodate rotation of the rotatable C-mount coupler assembly therein.
11. A method for orienting an endoscope image on a display comprising:
providing a C-mount coupler carrying an image sensor for displaying an image on a display, wherein the C-mount coupler carries at least one of an accelerometer and a gyroscope carried by the C-mount coupler, wherein the C-mount coupler is rotatably disposed in a handle, wherein electrical leads extend from the at least one accelerometer and gyroscope to a fixed location in the handle, wherein the electrical leads are configured with a slack portion in an interior of the handle to accommodate rotation of the rotatable C-mount coupler assembly therein;
attaching the C-mount coupler to an endoscope;
acquiring signals from the at least one accelerometer and gyroscope caused by rotation of the C-mount coupler; and
rotating the image on the display in response to the signals to correct an orientation to a selected configuration.
12. The method of claim 11 , further comprising rotating the C-mount coupler and manipulating the image electronically.
