Abstract
Abstract A surgical suction tip comprises a tubular body portion (2) with a hollow tip portion (6) at one end communicating into the body portion (2), and a cap portion (12) releasably closing the other end, a tubular connecting portion (14) mounted externally on the cap portion (12) communicating through a cap portion (12) into the body portion (2). A hollow filter member (26) within the body portion (2) defines an annular chamber (30) between the filter member (26) and the body portion (2) and communicating with the tubular connecting portion (14) through the cap portion (12), a plurality of apertures (31) in the filter member (26) connecting the interior of the filter member (26) with said annular chamber (30). The body portion (2) has locating means (20) thereon locating one end of the filter member (26) within the body portion (2), while the other end of the filter member (26) is closed. Waste material flows from the tip portion (6) into the hollow interior of the filter member (26) and thence to the annular chamber (30) and to the tubular connecting portion (14).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
243 words
A surgical suction tip comprising a tubular body portion (2) having a hollow, reduced-diameter tip portion (6) at one end thereof the bore (8) of which communicates into the interior of the body portion (2), a releasable cap portion (12) closing the other end of the body portion (2) and provided with a tubular connecting portion (14) externally thereof the bore (16) of which communicates through an aperture in the cap portion (12) into the interior of the body portion (2), and a hollow filter member (26) located within the body portion (2) to define a chamber (30) of generally annular transverse section between the filter member (26) and the inner wall of the body portion, the filter member (26) being provided with a plurality of apertures (31) therein interconnecting the interior of the filter member (26) with said annular chamber (30), characterised in that the body portion (2) has integrally formed therein, adjacent the tip portion (6) thereof, location means (20) to receive thereon and locate one end (28) of the filter member (26) within the body portion (2) such that material entering the body portion (2) through the tip portion (6) flows into the hollow interior of the filter member (26), the other end (34) of the filter member (26) being closed, and the annular chamber (30) within the body portion (2) being in communication with the tubular connecting portion (14) by way of said aperture in the cap portion 12.
Claim 2
Dependent Claim
243 words
A surgical suction tip comprising a tubular body portion (2) having a hollow, reduced-diameter tip portion (6) at one end thereof the bore (8) of which communicates into the interior of the body portion (2), a releasable cap portion (12) closing the other end of the body portion (2) and provided with a tubular connecting portion (14) externally thereof the bore (16) of which communicates through an aperture in the cap portion (12) into the interior of the body portion (2), and a hollow filter member (26) located within the body portion (2) to define a chamber (30) of generally annular transverse section between the filter member (26) and the inner wall of the body portion, the filter member (26) being provided with a plurality of apertures (31) therein interconnecting the interior of the filter member (26) with said annular chamber (30), characterised in that the body portion (2) has integrally formed therein, adjacent the tip portion (6) thereof, location means (20) to receive thereon and locate one end (28) of the filter member (26) within the body portion (2) such that material entering the body portion (2) through the tip portion (6) flows into the hollow interior of the filter member (26), the other end (34) of the filter member (26) being closed, and the annular chamber (30) within the body portion (2) being in communication with the tubular connecting portion (14) by way of said aperture in the cap portion 12.
Claim 3
Dependent Claim

A surgical suction tip as claimed in claim 1 in which the filter location means comprises a tubular member (20) extending coaxially within the body portion (2), the bore (22) thereof forming a continuation of the bore (8) through the tip portion (6), the one end (28) of the filter member (26) being a push-fit over said tubular member (20).
Claim 4
Dependent Claim
63 words
A surgical suction tip as claimed in claim 2 in which the tubular member (20) is provided with a plurality of circumferentially-spaced, axially extending ribs (24) on the outer wall thereof for abutment by the one end (28) of the filter member (26) to locate said filter member (26) axially relative to the tubular member (20) and therefore to the body portion (2).
