1. Technical Field
The present disclosure relates generally to gas enhanced electrosurgical instruments. More particularly, the present disclosure relates to a supply manifold for use with a gas enhanced electrosurgical instrument having multiple material supply cylinders.
2. Background of Related Art
Various surgical instruments are known for treating tissue. For example, surgical instruments used for tissue division, dissection, ablation, or for arresting blood loss and coagulation are well-known. In a particular application, for example in a coagulation instrument, an electrode is used in conjunction with a heated probe to arrest bleeding.
Some prior art devices include a tube-like coagulation instrument in which an ionizable gas is supplied to the instrument and ionized by the electrode. The provision of an atmosphere of ionized gases is beneficial because it helps focus the energy adjacent the electrode and it displaces oxygen from the area and reduces oxidative stress of the tissue. The gas is propelled from the instrument toward the tissue.
Many surgical procedures are enhanced by the use of wound mediating substances to assist in the healing of tissue. The substances may include blood clotting factors, wound closing adhesives, growth factors, interleukins, cytokines, inflammatory mediating factors, chemokines, meta-metalloproteinase or other biochemicals known to mediate wound healing.
In certain surgeries it may be advantageous to provide other fluids, such as, for example, saline, various dyes, etc. to the surgical instrument for application to tissue. In some instances, it may be advisable to provide one or more of these fluids to the tissue at the same time.
The present disclosure relates to a fluid supply manifold for use with a surgical instrument to provide various fluids from balk or canister fluid supply sources to the surgical instrument. The fluid supply manifold generally includes a housing having at least two connection ports for receipt of sources of fluid supply. A flow port is provided on each of the connection ports to pass the fluid through the housing. In one embodiment, the housing defines a mixing chamber that is in fluid communication with each of the flow ports so as to mix the fluids supplied through the connection ports. The housing also includes a discharge tube that is in fluid communication with the mixing chamber. Control valves are associated with the connection ports to regulate the flow of fluid into the housing. The control valves are operated by an actuator associated with a surgical instrument assembly. The housing may also include a gas inlet port that is in fluid communication with the mixing chamber.
Needles, defining fluid flow paths, are associated with the connection ports for piercing a septum associated with various fluid supply sources. The fluid supply sources may include bulk sources or individual fluid supply canisters. The connection ports include O-rings for sealing engagement with the fluid supply sources. In one embodiment, the connection ports are threaded to receive a corresponding thread on a fluid supply source. In an alternative embodiment, the external fluid supply source is affixed within the connection port in a press fit fashion such that the needle is forced through a septum of the fluid supply source.
In an alternative embodiment of the manifold, each connection port includes a flow tube passing through the housing. Control valves are positioned between a flow port of the connection port and the flow tubes. The flow tubes exit the housing through a neck, which is also used to connect the manifold to a surgical instrument or an actuator assembly.
The present disclosure also relates to a surgical instrument assembly including a surgical instrument having a fluid flow tube that includes a discharge port at a distal end of the surgical instrument. The surgical instrument assembly also includes an actuator assembly for controlling the flow of fluids through the fluid flow tube as well as a manifold supplying at least one or more sources of fluid to the fluid flow tube. In one embodiment, the manifold is attached to the actuator of the actuator assembly. In an alternative embodiment, the manifold is attached to the surgical instrument. The manifold can be attached to a proximal end of the surgical instrument or can be attached to a mixing chamber associated with the surgical instrument.
The present disclosure also relates to a gas enhanced electrosurgical instrument assembly that includes an electrosurgical instrument having a fluid flow tube including a fluid discharge port at a distal end of the surgical instrument. The instrument assembly also includes a generator for providing a source of energy to the electrosurgical instrument and a manifold for supplying one or more sources to the fluid flow tube of the electrosurgical instrument. An actuator assembly, having an actuator, is provided for controlling the source of energy provided by the generator and the flow of fluids from the manifold to the fluid flow tube of the electrosurgical instrument assembly. In one embodiment, the manifold is affixed to the actuator assembly. In an alternative embodiment, the manifold is affixed to the electrosurgical instrument.

Electrosurgical instrument 12 generally includes a housing 18 having an opening 20 at a distal end 22 thereof. The energy provided by energy generator 14 ionizes the gas supplied by actuator assembly 16 such that the ionized gas is propelled out of opening 20 to form an energy stream ES as electrosurgical instrument 12 is used to apply energy to tissue. A flow tube 24 extends between actuator 16 and distal end 22 of housing 18 to conduct the flow of fluids between actuator assembly 16 and electrosurgical instrument 12. Flow tube 24 has a fluid discharge port 26 at a distal end 28 of flow tube 24 which is positioned adjacent opening 20 electrosurgical instrument 12. While not specifically shown, an electrode is provided within electrosurgical instrument adjacent opening 20 so as to ionize the gas flowing through opening 20 and facilitate application of energy to tissue T. Flow tube 24 extends through a proximal end 30 electrosurgical instrument 12 such that a proximal end 32 of flow tube 24 is connected to actuator assembly 16. In this disclosed embodiment, the source of gas may be entirely contained within actuator assembly 16 or may be provided by an external source routed through actuator assembly 16. Additionally, the source of gas may be provided from a manifold associated with actuator assembly 16 or directly with electrosurgical instrument 12 in a manner described in more detail hereinbelow.
Generator 14 is of the type used to provide sources of energy, such as RF energy, to various electrosurgical instruments for use in cutting or coagulating tissue. Particularly useful generators 14 are the types available from ValleyLab—a division of Tyco Healthcare Group LP. Generator 14 is connected to electrosurgical instrument 12 by an energy cable 34. An energy return path 36 extends between generator 14 and a return pad 38. In use, return pad 38 is typically affixed to a portion of a patient to provide a complete flow of energy from generator 14 through electrosurgical instrument 12 to cut or coagulate tissue at a wound W, passed through underlying tissue T and into return pad 38 and thus back through return path 36 to generator 14. A control wire 40 extends between actuator 16 and generator 14 such that the energy provided by generator 14 to electrosurgical instrument 12 is controlled by actuator assembly 16. In some applications, a pressure relief valve 42 may be provided on electrosurgical instrument 10 to purge any built up fluid pressure within flow tube 24 prior to or during surgery.

In one particular embodiment, manifold 50 is provided with a gas inlet 90 for receipt of a pressurized source of gas. Gas flowing through gas inlet 90 will assist in atomizing any liquid supplied by the various supply sources affixed to connection ports 54, 56, 58 and 60. As shown, by orienting gas inlet 90 at a substantially 90° angle to flow ports 66, 68, 70 and 72, the flow of pressurized gas through gas inlet 90 creates a Venturi effect to assist in drawing the fluids out of various non-pressurized supply sources and atomize the fluids within the gas stream.
Referring to
In this particular embodiment, the connection port by the manifold 50 is in the form of a connection port body 104, which may be integral with manifold 50 or may be a separate part that is threaded or otherwise attached to manifold 50. Connection port body 104 includes a threaded bore 106 that is configured to mate with threaded surface 100 of supply canister 92. Connection port body 104 further includes a needle 108 for piercing septum 102 on supply canister 92. A fluid flow path 110 is provided through connection port body 104 and needle 108 to allow fluids to flow from fluid chamber 96 after septum 102 has been pierced. As noted hereinabove, various control valves are provided on manifold 50 in order to control the flow of fluids out of supply canister 92 and through fluid flow path 110. An O-ring may be provided within connection port body 104 in order to seal septum 102 within connection port body 104.
In use, neck 98 of supply canister 92 is inserted toward connector port body 104 and supply canister 92 is rotated such that threaded surface 100 matingly engages with threaded bore 106 of connector port body 104. Supply canister 92 is continued to be rotated until needle 108 pierces septum 102 and septum 102 engages O-ring 112 to seal supply canister 92 within connection port 104. In this manner, a supply canister 92 is inserted into manifold 50 such that the fluids contained within fluid chamber 96 are available for supply into manifold 50 through the various control valves and thus into electrosurgical instrument 10.
