DETAILED DESCRIPTION
[0032] The present disclosure relates to surgical instruments configured for treating tissue with light energy, e.g., surgical pencil 100 (
[0033] Turning to
[0034] With additional reference to
[0035] Sphere 142 is formed from a biocompatible material enabling transmission of light energy therethrough. More specifically, sphere 142 is configured to enable transmission of light energy within a tissue-treating wavelength range, e.g., a wavelength range from about 500 nm to about 2500 nm, therethrough, although other wavelength ranges may also be provided. Suitable materials for sphere 142 for this purpose include, but are not limited to sapphire, ruby, glass, crystal, combinations thereof, etc.
[0036] As noted above, energy transmission cable(s) 160 is configured to extend through cord 150 and surgical pencil 100 to interconnect the light energy surgical generator (not shown), activation switch 130, and tissue-treating portion 140 with one another. More specifically, a light energy transmission cable 160, e.g., a fiber optic cable or other suitable light energy transmission component, extends through shaft 120 to proximal throat 127, wherein light energy transmission cable 160 is proximally-spaced from sphere 142. Light energy transmission cable 160 is configured to direct light energy to sphere 142 which, in turn, focuses the light energy distally from distal end portion 122 of shaft 120 towards adjacent tissue to treat the adjacent tissue. Optics (not shown) may also be provided to facilitate the direction of light from the light energy transmission cable 160 to sphere 142. The shaft portions and/or other components of distal end portion 122 of shaft 120 are formed from material(s) with no or low light energy transmissibility to inhibit stray light energy from reaching tissue that is not intended to be treated. To this end, hoods, reflectors, and other structures (not shown) may be provided to redirect and/or confine light energy to a desired treatment area in the vicinity of sphere 142.
[0037] Referring still to
[0038] Turning to
[0039] In use, the supply of fluid F about sphere 142 maintains a positive pressure on sphere 142 so as to resiliently retain sphere 142 in a floating position, wherein sphere 142 protrudes distally from distal end portion 122 of shaft 120 despite opposing forces acting thereon from tissue in contact with sphere 142. This configuration helps maintain sphere 142 in contact with tissue as sphere 142 travels across irregular tissue surfaces, different tissue types, and other tissue features. The expulsion of fluid F from distal end portion 122 of shaft 120 also inhibits debris and other materials from collecting on sphere 142 and passing between sphere 142 and distal end portion 122 of shaft 120 and into cavity 124. In addition, the flow of fluid F helps cool tissue-treating portion 140 of surgical pencil 100 and/or surrounding tissue during tissue treatment.

[0042] One or more of the other light energy transmission cables 360 may serve as an optical sensor configured to sense one or more optical properties of tissue to determine tissue type, monitor tissue treatment, determine tissue temperature, determine electrical characteristics of tissue, etc. More specifically, one light energy transmission cable 360 may serve as an emitter and another light energy transmission cable 360 may collect light reflected from tissue to serve as a detector, although other configurations may also be provided. Optical tissue property information collected by one or more of the light energy transmission cables 360 may be communicated to the light energy surgical generator (not shown) to enable monitoring of tissue treatment, automatic shut off (for safety purposes and/or upon completion of tissue treatment), automatic adjustment of energy levels and/or waveforms during tissue treatment, and/or to inhibit treatment of certain tissue types. Suitable optical sensors and optical feedback mechanisms for the above purposes are disclosed in U.S. Patent Application Publication No. 2010/0296238, filed on May 16, 2011; U.S. Patent Application Publication No. 2010/0217258, filed on Jan. 30, 2008; and U.S. Patent Application Publication No. 2012/0226272, filed on Mar. 4, 2011, the entire contents of each of which are incorporated herein by reference.

[0045] Movable handle 540 is operably coupled to housing 510 and movable relative to a stationary handle portion 512 of housing 510 between an initial position and a compressed position. A drive assembly (not shown) extends through housing 510 and shaft 520 and is operably coupled between movable handle 540 and first and second jaw members 532, 534 of end effector assembly 530 such that movement of movable handle 540 between the initial position and the compressed position pivots one or both of jaw members 532, 534 relative to the other between a spaced-apart position and an approximated position to grasp tissue therebetween. A suitable drive assembly for these purposes is detailed in U.S. Patent Application Pub. No. 2013/0296922 to Allen, I V et al., the entire contents of which are hereby incorporated herein by reference.
[0046] Trigger 550 is operably coupled to housing 510 and movable relative thereto between an un-actuated position and an actuated position. A knife deployment assembly (not shown) extends through housing 510 and shaft 520 and is operably coupled between trigger 550 and a knife (not shown) associated with end effector assembly 530 such that movement of trigger 550 from the un-actuated position to the actuated position advances the knife from a retracted position to an extended position, wherein the knife extends between jaw members 532, 534 to cut tissue disposed therebetween. A knife and knife deployment assembly for these purposes is detailed in U.S. Patent Application Pub. No. 2013/0296922 to Allen, I V et al., previously incorporated herein by reference in its entirety.
[0047] Rotation knob 560 is operably associated with housing 510 and extends from either side thereof to enable manual manipulation by a user. Rotation knob 560 is coupled to shaft 520 which, in turn, supports end effector assembly 530 at a distal end portion thereof. As a result, rotation of rotation knob 560 in either direction rotates shaft 520 and end effector assembly 530 relative to housing 510 in a corresponding direction.
[0048] First and second activation switches 570, 580 are disposed on housing 510, while cord 600 extends from housing 510. Cord 600 is adapted to connect to a multi-output surgical generator configured to deliver bipolar RF energy and light energy to surgical forceps 500, although cord 600 may be bifurcated (or separate cords provided) and configured to couple to two separate generators, one for RF energy and the other for light energy. Alternatively, the RF energy-generating components and power components therefor may be disposed on or within housing 510 and/or the light energy-generating components and power components therefor may be disposed on or within housing 510. As an alternative to first and second jaw members 532, 534 being configured to supply RF energy to tissue grasped therebetween, other suitable energy modalities and/or manners of treating tissue grasped between first and second jaw members 532, 534 are also contemplated, e.g., ultrasonic, light energy, microwave, cryogenic, argon plasma, etc. Further, the light-energy tissue-treatment features of the present disclosure may be incorporated into other surgical instruments including energy-based surgical instruments, e.g., ultrasonic surgical instruments, microwave surgical instruments, cryogenic surgical instruments, etc., and/or mechanical surgical instruments, e.g., graspers, shavers, clip appliers, staplers, etc.
[0049] Cord 600 includes a plurality of electrical lead wires (not shown) extending therethrough and into housing 510. The electrical lead wires (not shown) are configured to electrically couple the generator with first activation switch 570 and jaw members 532, 534 of end effector assembly 530 such that RF energy is supplied to tissue-treating plates 533, 535 of jaw members 532, 534, upon activation of activation switch 570. As such, RF energy may be conducted through tissue grasped between tissue-treating plates 533, 535 of jaw members 532, 534, respectively, to treat, e.g., seal, tissue. Second activation switch 580, similar to activation switch 130 of surgical pencil 100 (
