Description

    REFERENCE TO RELATED APPLICATIONS
  • The present application claims the priority benefit of U.S. provisional patent application Ser. No. 60/548,301, filed on Feb. 27, 2004, the contents of which are incorporated herein by reference.
  • This application contains subject matter related to co-owned patent application No. 60/617,427, filed on Oct. 8, 2004, the contents of which are incorporated herein by reference.
  • FIELD OF THE INVENTION
  • The present invention is related generally to surgical instruments, and more particularly to an ultrasonic surgical shears and to a tissue pad for an ultrasonic surgical shears.
  • BACKGROUND OF THE INVENTION
  • Ultrasonic surgical instruments are known which include an ultrasonic surgical shears having an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, and a polytetrafluoroethylene tissue pad which is attached to the clamping arm and which includes a clamping surface. The clamping arm exerts a clamping force on a blood vessel which is positioned between the clamping surface of the tissue pad and the blade. The result of the ultrasonically-vibrating ultrasonic surgical blade and the clamping force on the blood vessel is a coaptation of the blood vessel (a bringing together of the walls of the blood vessel), a transection (a cutting) of the coapted blood vessel, and a coagulation (a sealing) of the coapted cut ends of the blood vessel. At the completion of a tissue transection, the ultrasonically-vibrating ultrasonic surgical blade contacts and cuts away some of the polytetrafluoroethylene tissue pad because of the frictional abrasion and frictional heat generated by the blade vibrating against the tissue pad. Exemplary devices are described in U.S. Pat. Nos. 5,322,055 and 6,325,811, the contents of which are incorporated herein by reference.
  • Still, scientists and engineers continue to seek improved ultrasonic surgical shears and improved tissue pads for ultrasonic surgical shears.
  • SUMMARY OF THE INVENTION
  • A first embodiment of an ultrasonic-surgical-shears tissue pad of the invention includes an ultrasonic-surgical-shears tissue pad body having a base material and at least one filler material which is a different material from the base material.
  • A second embodiment of an ultrasonic-surgical-shears tissue pad of the invention includes an ultrasonic-surgical-shears tissue pad body having adjoining first and second regions, wherein the first region includes a first material and wherein the second region includes a second material which is a different material from the first material.
  • A first embodiment of an ultrasonic surgical shears of the invention includes an ultrasonic surgical blade and a clamping arm operable to open and close toward the blade and having a transversely and resiliently flexible distal tip.
  • A second embodiment of an ultrasonic surgical shears of the invention includes an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, and a tissue pad attached to the clamping arm and having a clamping surface. At least a portion of the tissue pad is resiliently flexible in a direction substantially perpendicular to the clamping surface.
  • Several benefits and advantages are obtained from one or more of the embodiments of the invention. Having a tissue pad with a base material and at-least-one filler material allows the base material and the at-least-one filler material to be chosen with a different hardness, stiffness, lubricity, dynamic coefficient of friction, heat transfer coefficient, abradability, heat deflection temperature, and/or melt temperature to improve the wearability of the tissue pad which is important when high clamping forces are employed because tissue pads wear faster at higher clamping forces than at lower clamping forces. Applicants found, in one experiment, that a 15% graphite-filled polytetrafluoroethylene tissue pad showed substantially the same wear with a 7 pound clamping force as a 100% polytetrafluoroethylene tissue pad showed with a 1.5 pound clamping force. Having a flexible clamping arm and/or a flexible tissue pad should also improve the wearability of the tissue pad due to the ability of the flexible member to more evenly distribute the load across the entire surface of the tissue pad.
  • The present invention has, without limitation, application in straight or curved ultrasonic surgical blades as disclosed in the patents incorporated by reference and further in hand-activated instruments as well as in robotic-assisted instruments.

In another construction, not shown, the interface between the first and second regions is substantially parallel to the clamping surface (this can be visualized by rotating the tissue pad 18 in FIG. 2 by ninety degrees. In an additional construction, not shown, the interface is slanted with respect to the clamping surface at an angle between substantially 1 and 89 degrees, as can be appreciated by the artisan.
  • It is noted that the examples, illustrations, choices of materials, etc. described for the embodiment of the ultrasonic-surgical-shears tissue pad 10 of FIG. 1 are equally applicable to the embodiment of the ultrasonic-surgical-shears tissue pad 18 of FIG. 2 with the phrase “first material 28” replacing the phrase “base material 14” and with the phrase “second material 30” replacing the phrase “at-least-one filler material 16”.

The ultrasonic surgical blade, not shown in FIG. 5, moves through the first material 318 and then comes into contact with the second material 330. The second material 330 is selected for properties that make it abrade or melt less than the first material 318.
  • It is noted that the examples, illustrations, choices of materials, etc. described for the embodiment of the tissue pad 18 of FIG. 2 are equally applicable to the embodiments of the tissue pad 118, 218 and 318 of FIGS. 3-5. Other alternate embodiments to the tissue pad 18 are left to the artisan.
  • FIG. 6 illustrates a first embodiment of an ultrasonic surgical shears 32 of the invention. The ultrasonic-surgical-shears 32 includes an ultrasonic surgical blade 34 and a clamping arm 36 operable to open and close toward the blade 34 and having a transversely and resiliently flexible distal tip 38. By “resiliently flexible distal tip” is meant that the distal tip 38 resiliently flexes during clamping of the clamping arm 36 such as when the ultrasonic-surgical-shears 32 is used to transect and seal a blood vessel, disposed between the clamping surface 42 and the ultrasonic surgical blade 34, whose walls have been coapted by a clamping force applied via the clamping arm 36. In one implementation of the first expression, the ultrasonic surgical shears 32 also includes a tissue pad 40 attached to the clamping arm 36 and having a clamping surface 42, wherein the tissue pad 40 is resiliently flexible in a direction substantially perpendicular to the clamping surface 42.

The ultrasonic-surgical-shears 44 includes an ultrasonic surgical blade 46, a clamping arm 48 operable to open and close toward the blade 46, and a tissue pad 50. The tissue pad 50 is attached to the clamping arm 48 and has a clamping surface 52. At least a portion of the tissue pad 50 is resiliently flexible in a direction substantially perpendicular to the clamping surface 52. By “resiliently flexible” is meant that the tissue pad 50 resiliently flexes during clamping of the clamping arm 48 such as when the ultrasonic-surgical-shears 44 is used to transect and seal a blood vessel, disposed between the clamping surface 52 and the ultrasonic surgical blade 46, whose walls have been coapted by a clamping force applied via the clamping arm 48. In one illustration of the embodiment of the ultrasonic-surgical-shears 44, the tissue pad 50 includes a base material and at least one filler material as previously described for the tissue pad 10 of FIG. 1. In another illustration of the ultrasonic-surgical-shears 44, the tissue pad 40 includes a first material and a second material as previously described for the tissue pad 18, 118, 218 or 318 of FIGS. 2-5.
  • Several benefits and advantages are obtained from one or more of the embodiments of the invention. Having a tissue pad with a base material and at-least-one filler material allows the base material and the at-least-one filler material to be chosen with a different hardness, stiffness, lubricity, dynamic coefficient of friction, heat transfer coefficient, abradability, heat deflection temperature, and/or melt temperature to improve the wearability of the tissue pad which is important when high clamping forces are employed because tissue pads wear faster at higher clamping forces than at lower clamping forces. Applicants found, in one experiment, that a 15% graphite-filled polytetrafluoroethylene tissue pad showed substantially the same wear with a 7 pound clamping force as a 100% polytetrafluoroethylene tissue pad showed with a 1.5 pound clamping force. Having a flexible clamping arm and/or a flexible tissue pad should also improve the wearability of the tissue pad due to the ability of the flexible member to more evenly distribute the load across the entire surface of the tissue pad.
  • While the present invention has been illustrated by a description of several embodiments, it is not the intention of the applicants to restrict or limit the spirit and scope of the appended claims to such detail. Numerous other variations, changes, and substitutions will occur to those skilled in the art without departing from the scope of the invention. For instance, the ultrasonic surgical shears and the tissue pad of the invention have application in robotic assisted surgery taking into account the obvious modifications of such systems, components and methods to be compatible with such a robotic system. It will be understood that the foregoing description is provided by way of example, and that other modifications may occur to those skilled in the art without departing from the scope and spirit of the appended Claims.
