A system for conducting a vitrectomy includes: a gas source; a vitrector including a cutting mechanism that opens and closes according to a pressure at the vitrector; and a pulse-generating system receiving gas from the gas source and generating pulses at the vitrector. The pulses cause the pressure at the vitrector to vary according to a cycle, and the varying pressure at the vitrector causes the cutting mechanism of the vitrector to open and close. At a first time in the cycle, the pulse-generating system, raises the pressure at the vitrector to a maximum pressure. At a second time in the cycle, the pulse-generating system reduces the pressure at the vitrector to a minimum pressure that is greater than ambient, the pressure at the vitrector being maintained at least at the minimum pressure. The difference between the maximum pressure and minimum pressure is minimized to reduce gas consumption.

Bipolar electrosurgical forceps are provided with dual irrigating tubes that deliver irrigating liquid to the opposed surfaces of the tips of the forceps to prevent the sticking of body tissue to the tips. To reduce the manufacturing costs of the forceps and enable the forceps to be single use, disposable forceps, each tube of the dual irrigating tools is a plastic tube adhered along one of the opposing surfaces of the pair of forceps arms. Each tube also has a flat nozzle at the distal end of the tube that disburses irrigating liquid across the opposed surfaces of the forceps arm distal and tips.


A microsurgical instrument has a pair of operative surgical surfaces that are moved relative to each other in shearing or grasping procedures performed by the instrument. The instrument has a handle containing an elongate center rod with a ring mounted for reciprocating movement on the rod. A tube is secured to the ring and a shaft extends through the tube and is secured to the rod. The handle also includes a plurality of resilient arms that extend along the length of the rod and engage against a sliding surface of the ring on the rod. The plurality of actuator arms are alternatively manually compressed radially inwardly by the surgeons hand and released by the surgeons hand to allow the arms to flex radially inwardly and outwardly. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod and causes the tube and shaft to move axially relative to each other.

Disposable, bipolar electrosurgical forceps are designed to prevent the sticking of body tissue to the tips of the forceps and include a pair of electrode arms having lengths with opposite proximal and distal ends, with thin layers of biocompatible metal on the forceps arm distal ends and bipolar electrical conductors permanently secured to the forceps arm proximal ends.

A surgical device for use with a surgical site within a body includes a hub, a tube, and a compliant tip. The hub is configured to be connected to at least one of a vacuum source and an infusion source. The tube has a proximal end and an opposing distal end. The proximal end of the tube is connected to the hub. The compliant tip is connected to the tube and disposed adjacent the distal end of the tube, and includes a tip passage defined within the tip and a notch that defines a stepped opening in the tip. The stepped opening provides fluid communication between the at least one vacuum source and infusion source and the surgical site.

An irrigating cannula includes a hub having an inner passage and a side port extending through the hub and connecting to the inner passage. The inner passage is configured to receive an instrument, and a fluid passage is defined between the hub and the instrument. The fluid passage is configured to deliver a fluid through an incision in a body.

An illuminated surgical device includes a shaft and an optical fiber. The shaft includes a body having a central bore defined therein, and a passage extending through the shaft body to the central bore of the shaft. The shaft is configured for at least partial insertion into a human body. The optical fiber extends at least partially through the bore of the shaft such that light emitted from the optical fiber passes through the passage and is directed radially outward from the shaft.

Systems and methods for using a trocar system are disclosed. The system generally includes a handle having a first end a second end, a trocar disposed adjacent the first end of the handle, a plurality of cannulas disposed on the trocar simultaneously, and a drive system. The drive system is disposed for forward movement of the cannulas in a longitudinal direction away from the first end of the handle.

A biopsy system includes a cutting probe including a suction port, a suction line connected to the suction port, and a biopsy chamber fluidly connected to the cutting probe by the suction line. The biopsy chamber is positioned proximate the cutting probe such that the biopsy chamber is configured to receive and store a biological sample free from irrigation fluid.
