Patent number: 10179007Abstract: A surgical hand tool includes a handle that has an inner cavity. The handle has a proximal end and a distal end. The surgical hand tool also includes a primary tube extending outwardly from the cavity at the distal end, a reinforcing slider slidably disposed over the primary tube, and a biasing member coupled to the handle that biases the reinforcing slider away from the handle. The surgical hand tool also includes a retention mechanism coupled to the handle, the retention mechanism configured to engage and disengage with the reinforcing slider to control relative movement between the reinforcement slider and the handle.Type: GrantFiled: July 28, 2015Date of Patent: January 15, 2019Assignee: Medical Instrument Development Laboratories, Inc.Inventor: Erik William Peterson

Patent number: 10022268Abstract: Ocular fluid management systems and methods of operating the same. One ocular fluid management system includes a chamber, a diaphragm, a sensor, and a controller. The chamber includes a first portion and a second portion. The first portion is connected to an input line for receiving fluids into the first portion and an output line for discharging fluids from the first portion. The diaphragm is contained in the chamber and changes position based on a pressure difference between the first and second portions. The sensor detects a position of the diaphragm and transmits a signal based on the detected position. The controller is configured to receive the signal and control operation of at least one of a peristaltic pump and a vacuum pump based on the signal to maintain the diaphragm in a predetermined position.Type: GrantFiled: December 17, 2013Date of Patent: July 17, 2018Assignee: MEDICAL INSTRUMENT DEVELOPMENT LABORATORIES, INC.Inventor: Erik William Peterson

Publication number: 20110213317Abstract: A cannula for intraocular surgery including a cup, a tube including a wall and having a tube outer diameter, the tube extending from the cup to a distal end and defining a longitudinal axis. In one implementation, the distal end includes a first portion and a second portion, the first portion having a tip and being narrower than the second portion. A gripping section is formed in the wall. The gripping section has a diameter that is less than the tube outer diameter. The gripping section allows the sclera to deform into the reduced diameter in order to increase a retention force of the cannula in the eye while minimizing damage to the tissue of the eye.Type: ApplicationFiled: March 1, 2011Publication date: September 1, 2011Inventors: David E-bin Chen, Erik William Peterson

Publication number: 20100305596Abstract: A non-linear cut-rate multiplier for a vitreous cutter is provided whereby a signal from a host drive system may be multiplied in non-linear fashion to achieve significantly higher cut-rates for the vitreous cutter. Depending upon the cut-rate received from the host drive system, the multiplier may be configured to generate a subsequent cut-rate which is, potentially, linear for lower cut-rates of the host drive system and variably non-linear for higher cut-rates of the host drive system.Type: ApplicationFiled: March 3, 2010Publication date: December 2, 2010Inventors: Erik William Peterson, David E-bin Chen
