Surgical suction apparatus for applying suction to surgical debris to clear a surgical wound, said apparatus for being connected to a suction source, comprising:
- suction means including a first tube terminating at its forward and in a generally cylindrical filter provided with a plurality of radially disposed suction holes providing an entrance aperture through which said suction is applied to said surgical debris and terminating at its rearward end in an exit aperture through which surgical debris sucked through said entrance aperture exits said apparatus, and
- control means including a second tube coaxially surrounding said first tube and mounted for sliding, reciprocating, translating movement relative to said first tube to permit portions of said second tube to engage any surgical debris lodged in said entrance aperture to clear said entrance aperture and to permit portions of said second tube to alternately cover and uncover said suction holes to vary the effective size of said entrance aperture.
