A computer visual guidance system for guiding a surgeon through an arthroscopic debridement of a bony pathology, wherein the computer visual guidance system is configured to: (i) receive a 2D image of the bony pathology from a source; (ii) automatically analyze the 2D image so as to determine at least one measurement with respect to the bony pathology; (iii) automatically annotate the 2D image with at least one annotation relating to the at least one measurement determined with respect to the bony pathology so as to create an annotated 2D image; and (iv) display the annotated 2D image to the surgeon so as to guide the surgeon through the arthroscopic debridement of the bony pathology.

Method and apparatus for treating a joint, including the treatment of cam-type femoroacetabular impingement in a hip joint and pincer-type femoroacetabular impingement in a hip joint

A pump and a pump controller which uses an algorithm to quickly achieve and maintain a stable plasma field in a surgical site are provided. The algorithm calculates an electrical characteristic value to determine if a suction rate by the pump should be increased or decreased to achieve the stable plasma field. A method of using the pump and the pump controller is also provided.

Integrated pump control for dynamic control of plasma field

A pump with a controller for adjusting head pressure using a pressure boost is provided. The pressure boost may be dynamically adjusted during a surgical procedure based on the device being used and inflow and/or outflow settings.

Pump and means for controlling a pump

A pump and pump controller which uses an algorithm to quickly achieve and maintain a set pressure in a surgical site when high resistance hardware is being used is provided. The algorithm uses a gravity control type loop and uses pressure loss calculations to quickly respond to changing joint conditions. A method of using such a pump and pump controller is also provided.

Pressure control algorithm for high resistance hardware

An in-joint pump and control device comprising a pump and an in-joint sensor. The pump is configured to convey fluid to a body joint surgical site. The pump has an algorithm associated therewith to make calculations and to assist in controlling the operation of the pump. The in-joint sensor is operatively associated with the pump by at least a communication member. The in-joint sensor comprises a sheath, an integration member attached to the sheath, a pressure sensor connected to the integration member, and a temperature sensor adjacent the sheath. The pressure sensor is adapted to provide pressure information to the pump via the communication member. The temperature sensor is also adapted to provide temperature information to the pump via the communication member.

In-joint sensor for a surgical fluid management pump system

A pump system including a pump, an inflow cassette and an outflow cassette. The inflow cassette has a damping flexible membrane covering a damping region configured to dampen pressure pulsations in washing fluid passing through the damping region. The pump has a plurality of individually actionable pressing members that can each be individually actuated to pinch one of a plurality of suction tubes of the outflow cassette to at least partially prevent fluid flow through the one of the plurality of the suction tubes.

Cassette for a surgical fluid management pump system

A surgical pump system arrangement receives an inflow cassette and provides fluid flow to a surgical site in a joint of a patient. The arrangement calculates load coefficients for a pressure loss curve based on an identified inflow cannula and an identified endoscope utilized therewith. The arrangement determines if the cannula is disposed at a surgical site and if adequate fluid flow is provided. Further, the arrangement determines if the inflow cannula and endoscope are properly identified. The arrangement integrates with an identified or unidentified surgical device to adjust pump operation when the surgical device is operating. The arrangement maps actuators disposed on a surgical handpiece or footswitch to control operation of the pump system, including providing suction to an outflow path of a surgical device that is not operating. The arrangement also determines when an inflow pump cassette is not properly inserted into the pump.
