Surgical handpiece having directional fluid control capabilities

A handpiece configured for use in a medical system, comprising:

• a sleeve comprising a first port opening and a second port opening, wherein the first pot opening and the second port opening independently dispense fluid therethrough;
• a first fluid channel disposed within the handpiece and connected to the first port opening a second fluid channel disposed within the handpiece and connected to the second port opening;
• a first fluid flow restrictor disposed within the handpiece that variably restricts irrigation fluid flow through the first fluid channel independent of a pressure of the fluid at the first fluid flow restrictor;
• and
• a second fluid flow restrictor disposed within the handpiece that variably restricts irrigation fluid flow through the second fluid channel independent of a pressure of the fluid at the second fluid flow restrictor;
• wherein the handpiece:
• receives a signal from a control unit, wherein the signal is based on an input from a user, and electronically and individually controls a degree of opening of the first fluid flow restrictor and the second fluid flow restrictor to control the direction of the irrigation fluid flow through the first fluid channel and the direction of the irrigation fluid flow through the second fluid channel based on the signal.

A medical system comprising a system host and a control device connected to the system host, the medical system further comprising:

• a handpiece communicatively connected to the system host, comprising:
• a sleeve comprising a first port opening and a second port opening,
• wherein the first port opening and the second port opening independently dispense fluid therethrough,
• a first fluid channel disposed within the handpiece and connected to the first port opening,
• a second fluid channel disposed within the handpiece and connected to the second port opening,
• a first fluid flow restrictor disposed within the handpiece that variably restricts irrigation fluid flow through the first fluid channel independent of a pressure of the fluid at the first fluid flow restrictor;
• and
• a second fluid flow restrictor disposed within the handpiece that variably restricts irrigation fluid flow through the second fluid channel independent of a pressure of the fluid at the second fluid flow restrictor;
• wherein the control device:
• receives input from a user, and
• generates a control signal based on the input to control an amount of irrigation fluid and direction of irrigation fluid dispensed by the first port opening and the second port opening based on the input received from the user;
• wherein the handpiece:
• receives the control signal, and
• electronically and individually controls a degree of opening of the first fluid flow restrictor and the second fluid flow restrictor, respectively, to control the amount of irrigation fluid and direction of the irrigation fluid flow through the first fluid channel and the amount of irrigation fluid and direction of the irrigation fluid flow through the second fluid channel based on the control signal.

A medical system comprising:

• a system host device;
• a handpiece connected to the system host device comprising:
• a sleeve having a first port opening and a second port opening wherein the first port opening and the second port opening independently dispense fluid therethrough,
• a first fluid channel connected to the first port opening,
• a second fluid channel connected to the second port opening,
• a first fluid flow restrictor that restricts irrigation fluid flow through the first fluid channel, and
• a second fluid flow restrictor that restricts irrigation fluid flow through the second fluid channel;
• and
• a controller communicatively connected to the system host device;
• wherein the system host device comprises instructions that when executed cause the system host to provide signals to the handpiece to electronically and independently control the first fluid flow restrictor and the second fluid flow restrictor to control the direction of the fluid flow through the first fluid channel and the direction of the fluid flow through the second fluid channel based on input received at the controller from a user, and wherein the control of the first fluid flow restrictor and second fluid flow restrictor is independent of a pressure of the fluid flow through the first fluid channel and the second fluid channel.
