Abstract
Abstract A vacuum sleeve is disclosed for removing severed tissue from a surgical site. The vacuum sleeve is used in conjunction with a surgical appliance having a cutting element and the vacuum sleeve is connected to a vacuum source. The vacuum sleeve includes an elongated body member having a distal and a proximal end. The body member defines an internal passageway which extends between the distal and proximal ends of the body member. The internal passageway removably receives therein the surgical appliance and the distal end of the body member defines a aperture such that when the surgical appliance is disposed within the internal passageway, the cutting element of the surfical appliance extends through the aperture thereby enabling the cutting element to sever tissue from the surgical site. The internal passageway is connected to a vacuum source such that in use of the surgical appliance, when tissue is severed from the surgical site, the severed tissue is drawn from the surgical site through the aperture and along the internal passageway towards the source of vacuum.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
221 words
An adaptor vacuum sleeve for removing severed tissues from a surgical site for use with a self-contained cutting instrument having a cutting element and for connection to a vacuum source, comprising: an externally applied adapter sleeve means for removably receiving a self-contained cutting instrument; said adaptor sleeve means including an elongated body member having a distal end and a proximal end with an internal passageway means extending therebetween; said internal passageway means of said elongated body member being formed for receiving in use said self-contained cutting instrument therein; an aperture in said elongated body member enabling said cutting element of the cutting instrument in use to extend through said elongated body member to sever tissue from the surgical site; seal means located at said proximal end of said elongated body member for forming a seal between said cutting instrument and said elongated body member; and said seal means being flexible for resiliently engaging said self-contained cutting instrument at said proximal end of said elongated body member; a vacuum port in fluid communication with said internal passageway means of said elongated body member and being connectable to the vacuum source for removing tissue severed from the surgical site by drawing the removed tissue through said aperture and along said internal passageway means of said elongated member by action of the vacuum source.
Claim 2
Dependent Claim
221 words
An adaptor vacuum sleeve for removing severed tissues from a surgical site for use with a self-contained cutting instrument having a cutting element and for connection to a vacuum source, comprising: an externally applied adapter sleeve means for removably receiving a self-contained cutting instrument; said adaptor sleeve means including an elongated body member having a distal end and a proximal end with an internal passageway means extending therebetween; said internal passageway means of said elongated body member being formed for receiving in use said self-contained cutting instrument therein; an aperture in said elongated body member enabling said cutting element of the cutting instrument in use to extend through said elongated body member to sever tissue from the surgical site; seal means located at said proximal end of said elongated body member for forming a seal between said cutting instrument and said elongated body member; and said seal means being flexible for resiliently engaging said self-contained cutting instrument at said proximal end of said elongated body member; a vacuum port in fluid communication with said internal passageway means of said elongated body member and being connectable to the vacuum source for removing tissue severed from the surgical site by drawing the removed tissue through said aperture and along said internal passageway means of said elongated member by action of the vacuum source.
