Disposable tip assembly for laser surgical device
View Patent ↗A multi-component sterile, disposable tip apparatus for laser surgical devices is provided and features assembly for alignment of a self-contained optical fiber to the surgical device and releasably locking assembly between the tip and device.
1. A disposable tip assembly for a laser surgical device, the tip assembly comprising:
a hollow sleeve having a first opening for removably receiving a portion of the laser surgical device and a second opening defined in a distal end thereof, wherein the sleeve includes a plurality of spaced apart longitudinally extending internal ribs adapted to be received in corresponding slits on the laser surgical device,
a tip member having a hollow interior and that is partially received in the second opening in the sleeve,
a connector having an orifice extending axially therethrough, wherein at least a portion of the connector is received in the hollow interior of the tip member, and
an optical fiber that extends through the axial orifice of the connector and the hollow interior of the disposable tip member.
2. The disposable tip assembly of claim 1 wherein the connector includes a housing and a probe, wherein the housing is received in the disposable tip member and the probe extends into the hollow sleeve.
3. The disposable tip assembly of claim 2 wherein the housing comprises a magnetic material.
4. The disposable tip assembly of claim 3 wherein the housing has a larger diameter than the probe.
5. The disposable tip assembly of claim 1 wherein the tip member tapers to a discharge tip end.
6. The disposable tip assembly of claim 5 wherein the sleeve defines a longitudinal axis, and wherein the discharge tip end is at a right angle to the sleeve longitudinal axis.
7. The disposable tip assembly of claim 1 wherein the connector comprises a magnetic material.
8. A disposable tip assembly for a reusable surgical laser treatment device, the tip assembly comprising:
a) a hollow sleeve that defines a longitudinal axis and is adapted to releasably fit on the reusable surgical laser treatment device, wherein the sleeve includes a plurality of spaced apart longitudinally extending internal ribs adapted to be received in corresponding slits on the reusable laser surgical device,
b) a cannula member that includes a first end having a diameter and a second end that tapers to a discharge tip end,
c) an optical fiber axially positioned within the tip assembly and extending beyond the discharge tip end, and
d) a connector for releasably connecting the sleeve to the reusable surgical laser treatment device, wherein the connector includes a housing having a diameter that is smaller than the first end of the cannula, such that the housing is received in the cannula, and a probe that is adapted to extend into the reusable surgical laser treatment device, and wherein the housing and the probe cooperate to define a longitudinal opening through which the optical fiber extends.
9. The disposable tip assembly of claim 8 wherein the discharge tip end is at a right angle to the sleeve longitudinal axis.
10. The disposable tip assembly of claim 8 wherein the connector comprises a magnetic material.
11. The disposable tip assembly of claim 8 wherein the housing comprises a magnetic material.
12. The disposable tip assembly of claim 8 wherein the housing has a larger diameter than the probe.
