SURGICAL DEVICE HAVING A COMPLIANT TIP WITH A STEPPED OPENING
A surgical device for use with a surgical site within a body includes a hub, a tube, and a compliant tip. The hub is configured to be connected to at least one of a vacuum source and an infusion source. The tube has a proximal end and an opposing distal end. The proximal end of the tube is connected to the hub. The compliant tip is connected to the tube and disposed adjacent the distal end of the tube, and includes a tip passage defined within the tip and a notch that defines a stepped opening in the tip. The stepped opening provides fluid communication between the at least one vacuum source and infusion source and the surgical site.

2 . The surgical device of claim 1 , wherein the tip has an outer diameter defined by a circumferential sidewall of the tip, the notch extending radially inward from the circumferential sidewall to a depth, wherein a ratio between the depth and the outer diameter is between about 0.25 and about 0.75.
3 . The surgical device of claim 1 , wherein the tip has a first length protruding longitudinally outward from the distal end of the tube, and the notch has a second length extending from a distal end of the tip towards a proximal end of the tip, wherein the ratio of the second length to the first length is between about 0.25 and about 0.75.
4 . The surgical device of claim 1 , wherein the tip includes a circumferential sidewall extending from a proximal end of the tip to a distal end of the tip, the tip passage defined within the circumferential sidewall, the notch defined by a first surface of the sidewall and a second surface of the sidewall, wherein the first surface is oriented at an angle of between about 90 degrees and about 135 degrees with respect to the second surface.
5 . The surgical device of claim 4 , wherein the first surface is oriented substantially perpendicular to the second surface.
6 . The surgical device of claim 4 , wherein the circumferential sidewall extends along a longitudinal direction of the tip, one of the first and second surfaces being oriented substantially perpendicular to the longitudinal direction.
7 . The surgical device of claim 1 , wherein the tip has an outer diameter sized to be received within the distal end of the tube.
8 . The surgical device of claim 1 , wherein the tip is fabricated from at least one of silicone rubber and polyurethane.
9 . The surgical device of claim 1 , wherein the tip is connected to the tube by an interference fit.
10 . The surgical device of claim 1 , wherein a distal portion of the tip has a first stiffness, and a proximal portion of the tip has a second stiffness, wherein the first stiffness is less than the second stiffness.
11 . The surgical device of claim 1 , further comprising an illumination device disposed within at least one of the tube and the compliant tip, the illumination device configured to transmit light from a light source to the surgical site.
12 . A surgical device for use with a surgical site within a body, the surgical device having a proximal end and an opposing distal end, the proximal end configured to be connected to at least one of a vacuum source and an infusion source, the surgical device comprising:
a tube having a proximal end, an opposing distal end, and an internal tube passage defined therebetween; and
a compliant tip connected to the tube and disposed adjacent the distal end of the tube, the tip having a distal end that extends beyond the distal end of the tube, the tip including a tip passage defined therein and a notch defining a stepped opening in the tip, the stepped opening providing fluid communication between the at least one vacuum source and infusion source and the surgical site.
13 . The surgical device of claim 12 , wherein the tip is disposed within the internal tube passage, and the distal end of the tip protrudes outward from the internal tube passage.
14 . The surgical device of claim 12 , wherein the tip has an outer diameter defined by a circumferential sidewall of the tip, the notch extending radially inward from the circumferential sidewall to a depth, wherein a ratio between the depth and the outer diameter is between about 0.25 and about 0.75.
15 . The surgical device of claim 12 , wherein the tip has a first length protruding longitudinally outward from the distal end of the tube, and the notch has a second length extending from the distal end of the tip towards a proximal end of the tip, wherein the ratio of the second length to the first length is between about 0.25 and about 0.75.
16 . The surgical device of claim 12 , wherein the tip includes a circumferential sidewall extending from a proximal end of the tip to the distal end of the tip, the tip passage defined within the circumferential sidewall, the notch defined by a first surface of the sidewall and a second surface of the sidewall, the first and second surfaces extending between an outer circumferential surface of the sidewall and an inner circumferential surface of the sidewall.
17 . The surgical device of claim 16 , wherein the circumferential sidewall extends along a longitudinal direction of the tip, the first surface extending along the longitudinal direction of the tip and the second surface extending along a circumferential direction of the sidewall.
18 . The surgical device of claim 17 , wherein the first surface is oriented at an angle of between about 90 degrees and about 135 degrees with respect to the second surface.
19 . The surgical device of claim 18 , wherein the first surface is oriented substantially perpendicular to the second surface.
20 . The surgical device of claim 12 , wherein a distal portion of the tip has a first stiffness, and a proximal portion of the tip has a second stiffness, wherein the first stiffness is less than the second stiffness.
