a first seal located proximate the first open end and having a first diameter, the first seal being configured to sealingly accommodate a tubular shank, of a first diameter, of a blade of the surgical cutting device; and a first seal holder on the first seal, the first seal holder configured to maintain the first seal in place; wherein the second open end of the body is configured as a barbed connector. ### Claim 2 (depends on 1) The medical device of claim 1, further comprising a second seal located proximate the second open end and having a second diameter that is less than the first diameter, the second seal being configured to sealingly accommodate a tubular shank, of a second diameter that is less than the first diameter, of a blade of the surgical cutting device; wherein if the tubular shank of the first diameter of the blade of the surgical cutting device is inserted, a terminus of the tubular shank extends through the first suction seal and does not extend to the second suction seal, and if the tubular shank of the second diameter of the blade of the surgical cutting device is inserted, a terminus of the tubular shank extends through the first suction seal and through the second suction seal. ### Claim 3 (depends on 2) The medical device of claim 2, further comprising at least one third seal located in the hollow tubular connector intermediate the first seal and the second seal, the third seal being configured to sealingly accommodate a tubular shank, of a third diameter that is less than the first diameter of the blade of the surgical cutting device and greater than the second diameter of the blade of the surgical cutting device. ### Claim 4 (depends on 1) The medical device of claim 1, wherein the first seal holder is at least one of snap fitted, ultrasonically welded, adhesively coupled, or heat-staked to the hollow tubular connector. ### Claim 5 (depends on 1) The medical device of claim 1, wherein the source of pressurized air is a manually-operated pressure bulb. ### Claim 6 (depends on 1) The medical device of claim 1, wherein the hollow tubular connector comprises a gradually decreasing outer diameter from the first open end to the second open end. ### Claim 7 (depends on 1) The medical device of claim 1, wherein the seal is a self-closing seal. ### Claim 8 A medical device, comprising: a squeeze bulb comprising a first end having an opening through which air is expelled upon squeezing of the squeeze bulb; and a hollow tubular connector having a first open end connected to and in contact with the first open end of the squeeze bulb in an in-line configuration, and having a second open end configured to be connected to a suction port of a surgical cutting device; wherein the squeeze bulb and the hollow tubular connector define a modular assembly that is connectable to the suction port to allow for a removal of an obstruction in the surgical cutting device. ### Claim 9 (depends on 8) The medical device of claim 8, wherein the modular assembly is connectable to the suction port through a valve.
