Cannula That Provides Bi-Directional Fluid Flow That Is Regulated By A Single Valve

US Patent:
2005004, Feb 24, 2005
Filed:
Sep 24, 2004
Appl. No.:
10/949957
Inventors:
Erik Todd - Brisbane CA, US
International Classification:
A61M005/00
US Classification:
604248000
Abstract:
A cannula useful for endoscopic surgery. The cannula includes an outer tube in which an inner tube is removably seated. A surgical instrument can be positioned at the surgical site through the inner tube and irrigation fluid can be flowed to the surgical site through the inner tube. The tubes are spaced from each other to form a channel through which fluid can be selectively withdrawn from the surgical site. Fluid flow to and from the surgical site through the cannula is controlled by a valve assembly that has a single valve cock. The valve cock can be positioned to allow maximum irrigation flow/no suction flow or no irrigation flow/maximum suction flow. Bores internal to the valve cock are shaped so that, while the suction flow is initially incrementally increased, the irrigation flow is at a constant level.

Endoscope With Integrated Light Source

US Patent:
2006017, Aug 3, 2006
Filed:
Jul 11, 2005
Appl. No.:
11/179113
Inventors:
Erik Todd - Redwood City CA, US
Hasan Ertas - Sunnyvale CA, US
Andrew J. Hamel - San Mateo CA, US
Assignee:
Stryker Corporation - Kalamazoo MI
International Classification:
G03B 29/00
US Classification:
396017000
Abstract:
An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate. The light source unit is integrated into the proximal end of an endoscope and coupled directly to the optical fibers running to the tip of the endoscope. A plurality of such light source units may be integrated into the housing of an endoscope. Light emitted from each light source unit is directed to a distinctive section of the endoscope's tip and a doctor may control light output of each individual light source unit during a surgery.

Disposable Attachable Light Source Unit For An Endoscope

US Patent:
2006017, Aug 3, 2006
Filed:
Jul 11, 2005
Appl. No.:
11/179161
Inventors:
Erik Todd - Redwood City CA, US
Hasan Ertas - Sunnyvale CA, US
Andrew Hamel - San Mateo CA, US
Assignee:
Stryker Corporation - Kalamazoo MI
International Classification:
A61B 1/06
US Classification:
600178000
Abstract:
An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate, a light guide to collect light emitted from the LEDs and to couple the light into a group of optical fibers within the endoscope, and an interface to allow the light source unit to be removably attached to the endoscope at the endoscope's external light port. The LEDs therein may be overdriven by power for increased light output. When the LEDs reach their lifetime, the light source unit can be discarded.

Cannula That Provides Bi-Directional Fluid Flow That Is Regulated By A Single Valve

US Patent:
2003005, Mar 13, 2003
Filed:
Sep 12, 2001
Appl. No.:
09/952669
Inventors:
Erik Todd - Brisbane CA, US
International Classification:
A61N001/30
US Classification:
604/164020
Abstract:
A cannula () useful for endoscopic surgery. The cannula includes an inner tube () in which an inner tube () is removably seated. A surgical instrument () can be positioned at the surgical site through the inner tube and irrigation fluid can be flowed to the surgical site through the inner tube. The tubes are spaced from each other to form a channel through which fluid can be selectively withdrawn from the surgical site. Fluid flow to and from the surgical site through cannula is controlled by a valve assembly () that has a single valve cock (). The valve cock can be positioned to allow maximum irrigation flow/no suction flow or no irrigation flow/maximum suction flow. Bores () internal to the valve cock are shaped so that, while the suction flow is initially incrementally increased, the irrigation flow is at constant level.
