Surgical aspirator sleeve

Claim 2

A combination sleeve and surgical aspirator tube having a straight and a curved profile, the aspirator tubes having an enlarged medial portion, an elongate forward portion extending forwardly of the medial portion, a tip in the end of the forward portion opposite the medial portion and with no part of the forward portion being diametrically larger than the enlarged medial portion, said sleeve comprising: an elongate, nominally straight tubular body defining an internal channel having an open, rearward aspirator end and an enclosed, forward tip end, said tubular body formed from resilient, deformable material over the forward portion of the surgical aspirator tube to receive the forward portion of the aspirator tube therein and to assume the curved profile of the forward portion of the aspirator tube means to secure said tubular body to an aspirator tube to prevent longitudinal movement of said tubular body; wherein said body defining plural, spaced orifices at least in the forward tip portion, at a spaced distance rearwardly from the tip end, to communicate through the tubular body to allow passage of material to be aspirated into the internal channel defined by the tubular body; and, wherein the size of the internal channel of said tubular body is sufficiently larger than the exterior of the forward portion of the aspirator tube to enable the material passing into the channel through the orifices to flow through the internal channel between the interior of the tubular body and the exterior of the aspirator tube toward the forward tip of the aspirator tube.

Claim 3

The sleeve of claim 1, wherein the open, rearward end of the tubular body is resiliently expandable.

Claim 4

The sleeve of claim 1 further characterized by: the inner surface of the sleeve defining plural inwardly projecting elements to positionally maintain the aspirator tube being serviced in a medial position within the channel defined by the sleeve.

Claim 5

The sleeve of claim 1 further characterized by: the outer surface of the sleeve having plural outwardly projecting ribs to aid in spacing the orifices defined in the sleeve from tissue defining a surgical site.

Claim 6

A conversion sleeve for elongate aspirator tubes of both a straight and a curved profile, the aspirator tubes having a medial bulbous enlargement, an elongate forward section extending forwardly of the medial bulbous enlargement, a tip at the forward end of the forward section and with no portion of the forward section being diametrically larger than the medial bulbous enlargement, said conversion sleeve comprising: an elongate, nominally straight, resiliently deformable, tubular body defining an internal channel to receive substantially the entire length of and to conform to the curvature of the elongate forward section of the aspirator tube, said body having an open rearward aspirator end an a forward enclosed tip end means to secure said tubular body to an aspirator tube to prevent longitudinal movement of said tubular body; a plurality of spacedly arrayed orifices communicating through the tubular body, said orifices being spaced a distance from the enclosed tip end of the tubular body and including being located in the region of the body that overlaps the forward section of the aspirator tube; a plurality of spaced, radially inwardly extending positioning ribs to maintain the aspirator tube substantially in a medial position in the internal channel; and, wherein the size of the internal channel of the tubular body is sufficiently larger than the exterior of the forward portion of the aspirator tube to allow the material to be aspirated that passes through the orifices and into the channel to flow through the internal channel between the interior of the tubular body and the exterior of the aspirator tube toward the forward tip of the aspirator tube.

Claim 7

A conversion sleeve for elongate aspirator tubes of both a straight and a curved profile, the aspirator tubes having a medial bulbous enlargement, an elongate forward section extending forwardly of the medial bulbous enlargement, a tip at the forward end of the forward section and with no portion of the forward section being diametrically larger than the medial bulbous enlargement, said conversion sleeve comprising: an elongate, nominally straight, resiliently deformable, tubular body defining an internal channel to receive substantially the entire length of and to conform to the curvature of the elongate forward section of the aspirator tube, said body having an open rearward aspirator end an a forward enclosed tip end means to secure said tubular body to an aspirator tube to prevent longitudinal movement of said tubular body; a plurality of spacedly arrayed orifices communicating through the tubular body, said orifices being spaced a distance from the enclosed tip end of the tubular body and including being located in the region of the body that overlaps the forward section of the aspirator tube; a plurality of spaced, radially inwardly extending positioning ribs to maintain the aspirator tube substantially in a medial position in the internal channel; and, wherein the size of the internal channel of the tubular body is sufficiently larger than the exterior of the forward portion of the aspirator tube to allow the material to be aspirated that passes through the orifices and into the channel to flow through the internal channel between the interior of the tubular body and the exterior of the aspirator tube toward the forward tip of the aspirator tube.

Claim 8

The conversion sleeve of claim 5, wherein the open rearward end of said tubular body is resiliently expandable to snugly engage around the medial enlargement of the aspirator tube.

Claim 9

A conversion sleeve for elongate aspirator tubes of both straight and curved shapes, the aspirator tubes having a medial bulbous enlargement, a forward section extending forwardly of the medial bulbous enlargement, a tip at the forward end of the forward section and with no portion of the forward section being diametrically larger than the medial bulbous enlargement, said conversion sleeve comprising an elongate, resiliently deformable, tubular body defining an internal channel to accommodate the curvature of and releasably receive the forward section of the aspirator tube to be serviced, said body: having an open rearward aspirator end and an enclosed tip end; defining a plurality of spacedly arrayed orifices communicating therethrough, said orifices being spaced a distance from the enclosed tip end of the tubular body and being arrayed in radially spaced lines extending longitudinally of the tubular body; a plurality of spaced, radially inwardly extending positioning ribs to maintain an aspirator tube substantially in a medial position in the internal channel; wherein the outer surface of the sleeve body defining plural, spaced, radially outwardly extending spacing ribs; and, wherein the inner and outer spacing ribs being radially coincident and extending between the lines of spaced orifices.

Claim 10

A conversion sleeve for elongate aspirator tubes of both straight and curved shapes, the aspirator tubes having a medial bulbous enlargement, a forward section extending forwardly of the medial bulbous enlargement, a tip at the forward end of the forward section and with no portion of the forward section being diametrically larger than the medial bulbous enlargement, said conversion sleeve comprising an elongate, resiliently deformable, tubular body defining an internal channel to accommodate the curvature of and releasably receive the forward section of the aspirator tube to be serviced, said body: having an open rearward aspirator end and an enclosed tip end; defining a plurality of spacedly arrayed orifices communicating therethrough, said orifices being spaced a distance from the enclosed tip end of the tubular body and being arrayed in radially spaced lines extending longitudinally of the tubular body; a plurality of spaced, radially inwardly extending positioning ribs to maintain an aspirator tube substantially in a medial position in the internal channel; wherein the outer surface of the sleeve body defining plural, spaced, radially outwardly extending spacing ribs; and, wherein the inner and outer spacing ribs being radially coincident and extending between the lines of spaced orifices.
