Medical apparatus for suction and combination irrigation and suction

A finger-controlled handpiece disposed to provide combined irrigation and suction, the handpiece comprising:

• a shaft having a first end and a second end distal from the first end, the shaft also having a channel disposed from the first end of the shaft to the second end of the shaft and disposed to allow suction through the shaft;
• a nozzle coupled to the first end of the shaft, wherein the nozzle is a first component of the handpiece and the shaft is a second component of the handpiece;
• an inlet disposed through an exterior surface of the shaft and in operable communication with the channel, the inlet being disposed to be manually covered and uncovered by a first portion of a single hand to control suction through the shaft wherein the inlet is sized such that an amount of the inlet that is covered is controllable to cause different suction pressures that are controllable to differ in pressure during a same operation of the finger-controlled handpiece;
• a conduit having a first end disposed to receive irrigation solution and having a second end disposed to output at least one of a spray, droplet or stream of the received irrigation solution from the conduit;
• and
• a dispenser coupled to the first end of the conduit and capable of alternatively outputting each of a spray, a droplet or a stream of the irrigation solution to the conduit,
• wherein whether the spray, the droplet or the stream is output is based, at least, in part, on an amount of pressure applied to a pliable irrigation source by the single hand,
• wherein the dispenser is disposed to receive irrigation solution and output the spray, droplet or stream of the irrigation solution to the conduit,
• wherein the conduit is disposed to output the spray, droplet or stream of the irrigation solution, due to positive pressure applied, from the single hand, on the pliable irrigation source that is coupled to the dispenser and that contains the irrigation solution,
• and wherein the finger-controlled handpiece can concurrently control the amount of pressure applied to the pliable irrigation source and the volume of irrigation solution emitted from the pliable irrigation source such that the amount of pressure and the volume of irrigation solution emitted from the irrigation source is modifiable during operation of the finger-controlled handpiece and such that a first form of the irrigation solution is capable of being emitted from the dispenser at a first time and a second form of the irrigation solution is capable of being emitted from the dispenser at a second time, the first time and the second time being during the operation of the finger-controlled handpiece, wherein the first form is at least one of the spray, the droplet or the stream and the second form is at least one of the spray, the droplet or the stream, wherein the finger-controlled handpiece can be controlled during operation such that the first form differs from the second form,
• wherein the dispenser and the inlet are concurrently operable by the single hand,
• and wherein concurrent operation comprises:
• causing the dispenser to receive the irrigation solution based on depression of the pliable irrigation source by at least one of a second portion of the single hand or the first portion of the single hand, and wherein the finger-controlled handpiece is configured such that manual depression by the single hand on the pliable irrigation source controls whether the first form or the second form of the irrigation solution is output from the pliable irrigation source;
• and
• at least one of a covering or uncovering of the inlet by the first portion of the single hand.
