Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 words
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 providing an entrance aperture through which said suction is applied to said surgical debris and providing an exit aperture through which surgical debris sucked through said entrance aperture exits said apparatus, and control means including external cutting means for externally cutting any surgical debris lodged in said entrance aperture to thereby clear said aperture.
Claim 2
Dependent Claim
80 words
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 providing an entrance aperture through which said suction is applied to said surgical debris and providing an exit aperture through which surgical debris sucked through said entrance aperture exits said apparatus, and control means including external cutting means for externally cutting any surgical debris lodged in said entrance aperture to thereby clear said aperture.
Claim 3
Dependent Claim
78 words
Surgical apparatus according to Claim 1 wherein said suction means comprises a first tube terminating in a generally cylindrical filter provided with a plurality of radially dis-posed suction holes providing said entrance aperture, and wherein said cutting means comprises a second tube axially surrounding said first tube and mounted for sliding, reciprocat-ing, translating movement relative to said first tube to permit portions of said second tube to engage and cut said surgical debris lodged in said entrance aperture.
Claim 4
Dependent Claim
30 words
Surgical apparatus according to Claim 2 wherein said second tube is terminated in a generally annular cutting blade for engaging and cutting said surgical debris lodged in said entrance aperture.
Claim 5
Dependent Claim
82 words
Surgical apparatus according to Claim 1 wherein said suction means comprises a first tube terminating in a generally cylindrical filter provided with a plurality of radially dis-posed suction holes providing said entrance aperture, and where-in said control means comprises a second tube coaxially surround-ing said first tube and mounted for sliding, reciprocating, translating movement relative to said first tube to permit portions of said second tube to cover and uncover said suction holes to vary said suction applied to said surgical debris.
Claim 6
Dependent Claim
120 words
Surgical apparatus according to Claim 4 wherein said plurality of radially disposed suction holes are of different sizes and are axially disposed such that the smaller sized suction holes are forwardly of said generally cylindrical filter and said larger suction holes are rearwardly of said generally cylindrical filter whereby, upon said second tube being slid forwardly of said first tube, the number and size of said radially disposed suction holes exposed are decreased thereby reducing the suction applied and focusing the suction at the forward end of said first tube and, upon said second tube being slid rearwardly of said first tube, the size and number of said radially disposed suction holes exposed are increased thereby increasing the suction applied.
