Apr 3, 2002

Appl. No.:

10/116467

Inventors:

Theodore S. Wortrich - Newport Coast CA
Armand Maaskamp - Mission Viejo CA
Michael Ekinaka - Irvine CA

Assignee:

Surgin Inc. - Tustin CA

International Classification:

A61M 100

US Classification:

604 35, 95284, 55414

Abstract:

A fluid flow regulator of a smoke evacuation system for use with laparoscopic and endoscopic surgery is disclosed. The fluid flow regulator is comprised of a flow regulating means and a conduit connecting means. The flow regulating means in one embodiment includes a diaphragm and one or more orifices of predetermined diameter to provide a significant obstruction to the flow of fluid through the evacuation system. When operatively coupled to the pressurized surgical site, the fluid flow regulator makes possible the continuous evacuation of surgical smoke while simultaneously maintaining the pneumoperitoneum in a distended position for the duration of the laparoscopic procedure. Also disclosed is a method of using the fluid flow regulator to continually evacuate surgical smoke in the course of laparoscopic and endoscopic surgical procedures without deflating the pneumoperitoneum, which hereto for has been used by prior art systems to evacuate surgical smoke.

International Classification:

B23P019/04

US Classification:

Abstract:

A small case for protecting a microkeratome blade while allowing inspection and cleaning of the blade cutting edge incorporates adjacent walls which are hinged together to open and close relative to an inserted microkeratome blade. In position, when the case is closed the blade is set in a recess in one of the walls and held in position by an opposing surface on the other wall. Windows encompassing the cutting edge in each of the walls allow visual inspection and cleaning, if desired. When the case is opened, a converging guide groove extending from a side of one wall into the blade unit and to a point behind the cutting edge allows a surgeon to insert and guide a forceps into the blade unit so that it can be gripped and removed without contacting the cutting edge.

Inventors:

Theodore Wortrich - Newport Coast CA, US

International Classification:

A61F009/00

US Classification:

606166, 600452

Abstract:

A blade and holder combination for use with a microkeratome, and including means for improving mechanical stability when the blade is reciprocated during cutting, as well as a peripheral configuration minimizing local nonuniformities. Blades in accordance with the invention have a generally hemispherical posterior geometry that include an adjacent centralized ovoid coupling aperture and a small centrally disposed access slot that may include indicia for denoting blade type. The hemispherical geometry minimizes both local deformities and the processing needed to assure that the product functions to provide a clean, uniform surgical result.

Appl. No.:

6/892811

Inventors:

Theodore S. Wortrich - Mission Viejo CA

Assignee:

Sugrin Surgical Instrumentation, Inc. - Placentia CA

International Classification:

B67B 724
B67D 300
A61M 514
A61M 5245

US Classification:

222 81

Abstract:

A disposable system for enabling a succession of individuals to be supplied with a sterile medical solution during operative and other procedures utilizes a number of spaced apart, penetrable elastomerically sealed funnels branching from an outlet from the solution container or an attached drip chamber. A standard sterile administration set having a spike end may be inserted into the seal of a first funnel to provide flow to a first individual. After the first procedure is completed the conduit to the first funnel is clamped off and the sequence repeated, but with the spike end of a second administration set inserted for supply to solution to a second individual. This sequence may be repeated for a selectable number of branches, enabling valuable solution from a container to be used with minimum wastage but without danger of cross-contamination.

Appl. No.:

8/114207

Inventors:

Theodore S. Wortrich - Long Beach CA

Assignee:

Surgin Surgical Instrumentation, Inc. - Tustin CA

International Classification:

A61M 5178

US Classification:

604158

Abstract:

A thin bodied elongated surgical instrument for penetrating into a body cavity and thereafter being useful for performing surgical functions disposes an obturator within a cutting cannula. The obturator is spring mounted to retract within the cannula in response to resistance encountered at a body wall, but moves to an extended distal position inside the body cavity. In that position the obturator is manually or automatically locked in axial position, so that means at the extended end can be used in the surgical procedure without danger of cutting internal tissue or organs. This safety device facilitates initial insertion of an insufflation needle, and subsequent insertion and use of other instruments during laparoscopic surgery.

Inventors:

Theodore S. Wortrich - Long Beach CA

Assignee:

Surgin Surgical Instrumentation, Inc. - Placentia CA

International Classification:

A61M 100

US Classification:

604 30

Abstract:

A system for controlling the irrigation and aspiration functions in flow lines cooperative with a surgical control console employs a reusable receiver within which a disposable cassette is insertable. The cassette includes lines which must be sterile for each user, but cooperates with elements in the receiver to which it is detachably engaged. Slider bars within the receiver are arranged to transmit clamping forces against interior flexible lines such that shortened and simplified flow paths are used.
