Abstract

A medical suction and irrigation apparatus includes a suction/irrigation tip removably connected to a conventional suction/irrigation handpiece. Suction is provided through a suction tube which has a bypass conduit in the tip. The bypass conduit is directly connectable to a suction source so that aspirated debris passes through the tip to the suction source. The suction tube thus prevents aspirated debris from entering the conventional suction tube in the handpiece and contaminating the handpiece. The suction tube is also designed to have a maximum size to prevent the tip from clogging. The tip also has an irrigation tube for directing irrigation liquid to the irrigation site, and a connector which connects the irrigation tube to the handpiece so that the handpiece pumps fluid through the tip in a conventional manner. A flexible splash shield, slidably mounted to the irrigation tube, confines irrigation fluid to the local site.

Claims

1. A detachable suction tip for use with a suction handpiece, the handpiece having a suction lumen extending therethrough for removing irrigation fluid from an irrigation site, the tip comprising:

a suction tube for aspirating irrigation fluid from the irrigation site, the suction tube having a fluid bypass path within the detachable tip which channels aspirated irrigation fluid directly to a suction source so that aspirated fluid within the suction tube does not enter the handpiece suction lumen;

a connector for mechanically connecting the tip to the handpiece, the connector also having a plug for sealing the suction lumen in the handpiece;

an irrigation tube for directing the irrigation fluid to the irrigation site, the suction tube being within the irrigation tube.

2. A detachable suction and irrigation tip for use with an irrigation handpiece, the handpiece having a suction lumen and an irrigation lumen extending therethrough, the irrigation lumen directing irrigation fluid to an irrigation site, the tip comprising:

an irrigation tube for directing the irrigation fluid to the irrigation site;

a connector for detachably connecting the irrigation tube to the handpiece to provide fluid communication therebetween and for sealing the suction lumen in the handpiece; and

a suction tube for aspirating irrigation fluid from the irrigation site, the irrigation tube and suction tube being coaxially aligned, the suction tube having a fluid bypass path within the detachable tip which channels aspirated irrigation fluid directly to a suction source so that aspirated fluid within the suction tube does not enter the handpiece.

3. A detachable suction and irrigation tip for use with an irrigation handpiece, the handpiece having a suction lumen and an irrigation lumen extending therethrough, the irrigation lumen directing irrigation fluid to an irrigation site, the tip comprising:

an irrigation tube for directing the irrigation fluid to the irrigation site;

a connector for detachably connecting the irrigation tube to the handpiece to provide fluid communication therebetween and for sealing the suction lumen in the handpiece; and

a suction tube for aspirating irrigation fluid from the irrigation site, the suction tube being disposed in the irrigation tube, the suction tube having a fluid bypass path within the detachable tip which channels aspirated irrigation fluid directly to a suction source so that aspirated fluid within the suction tube does not enter the handpiece.

4. The tip as defined by claim 3 wherein the fluid bypass path passes through the irrigation tube.

5. A detachable suction and irrigation tip for use with an irrigation handpiece, the handpiece having a suction lumen and an irrigation lumen extending therethrough, the irrigation lumen directing irrigation fluid to an irrigation site, the tip comprising:

an irrigation tube for directing the irrigation fluid to the irrigation site;

a connector for detachably connecting the irrigation tube to the handpiece to provide fluid communication therebetween and for sealing the suction lumen in the handpiece; and

a suction tube for aspirating irrigation fluid from the irrigation site, the suction tube having a fluid bypass path within the detachable tip which channels aspirated irrigation fluid directly to a suction source so that aspirated fluid within the suction tube does not enter the handpiece; and

a splash shield slidably mounted on the tip.

6. A detachable suction and irrigation tip for use with an irrigation handpiece, the handpiece having a suction lumen and an irrigation lumen extending therethrough, the irrigation lumen directing irrigation fluid to an irrigation site, the tip comprising:

an irrigation tube for directing the irrigation fluid to the irrigation site;

a connector for detachably connecting the irrigation tube to the handpiece to provide fluid communication therebetween and for sealing the suction lumen in the handpiece; and

a suction tube for aspirating irrigation fluid from the irrigation site, the suction tube having a fluid bypass path within the detachable tip which channels aspirated irrigation fluid directly to a suction source so that aspirated fluid within the suction tube does not enter the handpiece; and

a fluid deflecting hood extending from the connector to deflect splashed irrigation fluid away from the handpiece.

7. A detachable suction and irrigation tip for use with an irrigation handpiece, the handpiece having a suction lumen and an irrigation lumen extending therethrough, the irrigation lumen directing irrigation fluid to an irrigation site, the tip comprising:

an irrigation tube for directing the irrigation fluid to the irrigation site;

a connector for detachably connecting the irrigation tube to the handpiece to provide fluid communication therebetween and for sealing the suction lumen in the handpiece; and

a suction tube for aspirating irrigation fluid from the irrigation site, the suction tube having a fluid bypass path within the detachable tip which channels aspirated irrigation fluid directly to a suction source so that aspirated fluid within the suction tube does not enter the handpiece; and

a protective covering fastened to the tip and covering the handpiece.

8. A detachable suction and irrigation tip for use with an irrigation handpiece, the handpiece having a suction lumen and an irrigation lumen extending therethrough, the irrigation lumen directing irrigation fluid to an irrigation site, the tip comprising:

an irrigation tube for directing the irrigation fluid to the irrigation site;

a connector for detachably connecting the irrigation tube to the handpiece to provide fluid communication therebetween and for sealing the suction lumen in the handpiece; and

a suction tube for aspirating irrigation fluid from the irrigation site, the suction tube having a fluid bypass path within the detachable tip which channels aspirated irrigation fluid directly to a suction source so that aspirated fluid within the suction tube does not enter the handpiece; and

the suction tube having a tube segment that diverts aspirated fluid away from the distal end of the handpiece.

9. A method of irrigating an irrigation site, the method comprising the steps of:

(a) providing a handpiece defining a handpiece irrigation lumen and a handpiece suction lumen;

(b) connecting the handpiece irrigation lumen to an irrigation fluid source;

(c) detachably connecting a tip to the distal end of the handpiece, the tip having a tip irrigation tube in fluid communication with the handpiece irrigation lumen, a tip suction tube for aspirating fluid from the site and a bypass fluid path in fluid communication with the tip suction tube, and

(d) connecting the bypass fluid path to a suction source.

10. The method of irrigating the irrigation site as defined by claim 9 wherein step (c) comprises the step of plugging the handpiece suction lumen.

11. The method of irrigating the irrigation site as defined by claim 9 further comprising the steps of:

(e) removing the tip from the handpiece;

(f) inserting a plug in the handpiece suction lumen; and

(g) inserting a plug in the handpiece irrigation lumen.

12. The method of irrigating the irrigation site as defined by claim 9 further comprising the steps of:

(h) removing the plug from the handpiece suction lumen;

(i) removing the plug from the handpiece irrigation lumen; and

(j) connecting a second tip to the handpiece, the second tip having a tip irrigation tube, and a tip suction tube that prevents aspirated fluid from communicating with the handpiece suction lumen.

13. An apparatus for irrigating an irrigation site comprising:

a handpiece having a lower end;

a tip connected to the handpiece and having a proximal end; and
