The present disclosure relates to the use of medical instruments. More particularly, the present disclosure is directed to vessel sealing devices.
A surgical forceps is a plier-like instrument which relies on mechanical action between its jaw members to grasp, clamp, and constrict tissue. Energy-based surgical forceps utilize both mechanical clamping action and energy, e.g., RF energy, ultrasonic energy, microwave energy, thermal energy, light energy, etc., to affect hemostasis by heating tissue and blood vessels to coagulate and/or cauterize tissue. Certain surgical procedures require more than simply coagulating/cauterizing tissue and rely on the unique combination of clamping pressure, precise energy control, and gap distance (i.e., the distance between opposing jaw members when closed about tissue) to “seal” tissue.
Typically, once tissue is treated, e.g., sealed, the surgeon has to accurately sever the tissue along the newly formed tissue seal. Accordingly, many surgical forceps have been designed which incorporate a knife or blade member that effectively severs the tissue after forming a tissue seal.
Vessel sealing instruments are used in many surgical procedures to seal and dissect tissue. Occasionally, during a surgical procedure, bleeding will occur while the surgeon is using the vessel sealing instrument. In such situations, the surgeon may be required to stop use of the vessel sealing instrument, remove it from the surgical site, and insert a separate suction device in order to clear the blood and other bodily fluids that have collected at the surgical site.
As shown in the drawings and described throughout the following description, as is traditional when referring to relative positioning on a surgical instrument, the term “proximal” refers to the end of the apparatus that is closer to the user and the term “distal” refers to the end of the apparatus that is farther away from the user. The term “clinician” refers to any medical professional (e.g., doctor, surgeon, nurse, or the like) performing a medical procedure involving the use of embodiments described herein.
In at least one aspect of the present disclosure, a forceps is provided that includes an end effector assembly having first and second jaw members attached at a distal end of a shaft. At least one of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. Each jaw member includes an electrically-conductive tissue-contacting surface adapted to connect to a source of energy to treat tissue grasped between the jaw members A suction system is disposed proximate the first and second jaw members and is configured to apply suction to a surgical site upon activation thereof.
In another aspect of the present disclosure, the suction system includes a tube attached to the shaft and is configured to connect to a low-pressure source. The tube may be disposed within the shaft and may be selectively slidable within the shaft from a retracted position to a deployed position. In the deployed position, at least a portion of the tube may be extended to a position distal to the jaw members.
In another aspect of the present disclosure, one of the first or second jaw members is fixed and integral with the shaft. The tube may be offset relative to the fixed jaw member.
In another aspect of the present disclosure, the forceps includes a blade disposed within the shaft and configured to cut tissue disposed between the jaw members. An actuator is configured to selectively deploy and retract the tube.
Another aspect of the present disclosure relates to a method for performing a surgical procedure including providing a vessel sealing device having two opposable jaw members operably connected to a shaft. At least one of the jaw members is configured to move relative to the other between an open position and a clamped position. A suction system is included proximate one or both of the jaw members.
The method also includes: grasping a vessel between the two jaw members and applying electrosurgical energy to seal tissue; and activating the suction system to remove bodily fluids from the surgical site during the surgical procedure.
The suction system may include a suction tube slidably disposed within the shaft of the vessel sealing device and the method may include the step of deploying the suction tube from a retracted position to a deployed position to remove fluid and debris from the surgical site upon activation of the suction system.
The method may include the steps of providing a vessel sealing device having two opposable jaw members operably connected to a shaft, where at least one of the jaw members is configured to move relative to the other between an open position and a clamped position, disposing a suction system proximate the first and second jaw members that is configured to apply suction to a surgical site upon activation thereof, grasping a vessel between the two jaw members, applying electrosurgical energy to seal tissue, and suctioning bodily fluids from a surgical site during the surgical procedure.
In another aspect of the present disclosure, a vessel sealing device includes an end effector assembly having first and second jaw members, at least one of the jaw members being movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. Each jaw member includes an electrically-conductive tissue-contacting surface adapted to connect to a source of energy to treat tissue grasped between the jaw members. A suction system is disposed proximate the first and second jaw members and is configured to apply suction to a surgical site upon activation thereof. The suction system includes a tube slidably disposed on or in the shaft radially outwardly of the second jaw member relative to a longitudinal axis of the shaft. The tube is configured to move between a retracted position wherein the tube is proximal of a distal end of the first and second jaw members to a deployed position wherein at least a portion of the tube extends distally relative to the distal end of the first and second jaw members.
The tube may be disposed within the shaft. The tube may also be connected to a suction tube deployment device that is operably connected to the housing. The suction tube deployment device may include an actuator that deploys the tube from the retracted position via a button, a handle, a mechanical deployment system, an electro-mechanical deployment system, a lever, or a slide.
The above and other aspects, features, and advantages of the present disclosure will become more apparent in light of the following detailed description when taken in conjunction with the accompanying drawings in which:

Forceps 10 also includes cable 8 that connects forceps 10 to an energy source, e.g., a generator “G”, or other suitable power source, although forceps 10 may alternatively be configured as a battery-powered device. Cable 8 includes a wire or wires (not shown) extending therethrough that has sufficient length to extend through shaft 12 in order to provide energy to at least one of tissue-contacting surfaces 112, 122 (
With continued reference to
Moveable handle 40 is ultimately connected to a drive assembly (not shown in
Rotating assembly 70 is rotatable in either direction about longitudinal axis “X-X” to rotate end effector assembly 100 about longitudinal axis “X-X.” Housing 20 houses the internal working components of forceps 10.
Forceps 10 may also include a ratchet assembly 31 for selectively locking the jaw members 110 and 120 relative to one another at various positions during pivoting. Ratchet assembly 31 may include graduations or other visual markings that enable the user to easily and quickly ascertain and control the amount of closure force desired between the jaw members 110 and 120.
In order to effectively “seal” tissue or vessels, two predominant mechanical parameters should be accurately controlled: 1) the pressure or closure force applied to the vessel or tissue; and 2) the gap distance between the conductive tissue contacting surfaces (electrodes).
Tissue pressures within a working range of about 3 kg/cm2 to about 16 kg/cm2 and, advantageously, within a working range of 7 kg/cm2 to 13 kg/cm2 have been shown to be effective for sealing arteries and vascular bundles.
In some embodiments, one of the jaw members, e.g., 120, includes at least one stop member 175 (see
With reference to
Each jaw member 110, 120 of end effector assembly 100 includes a proximal flange portion 111a, 121a, a distal jaw portion 111b, 121b, an outer insulative jaw housing 117, 127 and a tissue-contacting plate 112, 122, respectively. Proximal flange portions 111a, 121a of jaw members 110, 120 are pivotably coupled to one another about a pivot 103 for moving jaw members 110, 120 between the spaced-apart and approximated positions. Distal jaw portions 111b, 121b of jaw members 110, 120 are configured to support jaw housings 117, 127, and tissue-contacting plates 114, 124, respectively, thereon. Further, one of the jaw members, e.g., jaw member 120, may include an energy-based cutting member (not shown) disposed thereon, or a channel 115 for allowing a mechanical cutting member (not shown), e.g., a knife assembly as described above, to pass therethrough. Trigger 82 of trigger assembly 80 is operably coupled to the knife assembly (shown in
In embodiments having an electrical cutting member, the electrical cutting member can be similarly coupled to trigger 82 (
Tissue-contacting plates 112, 122 are formed from an electrically conductive material for conducting electrical energy therebetween for treating tissue, although tissue-contacting plates 112, 122 may alternatively be configured to conduct any suitable energy through tissue grasped therebetween for energy-based tissue treatment, e.g., tissue sealing. In embodiments having an energy-based cutting member (not shown), the energy-based cutting member may be formed from an electrically conductive material for conducting electrical energy between energy-based cutting member and one or both of tissue-contacting plates 112, 122 for electrically cutting tissue. Energy-based cutting member may alternatively be configured to conduct any suitable energy through tissue for electrically cutting tissue.
Tissue-contacting plates 112, 122 are coupled to an activation switch such as trigger 82 (

As shown, the suction system includes one or more tubes 113 connected to a low pressure source “L” via piping 9. Low pressure source “L” may be any device capable of providing a suction flow in tube 113, such as, but not limited to, a vacuum pump. The tube 113 may be contained within shaft 12 as shown in
In some embodiments, tube 113 may be disposed on or within forceps 10 in a fixed manner such that tube 113 may not slide longitudinally and is thus positioned at a fixed extension from shaft 12. However, as shown, tube 113 is slidably disposed within the forceps 10 and is selectively extendable via an actuator 199 such that movement of the actuator 199 from an un-actuated position to an actuated position causes tube 113 to translate between a retracted position and a deployed position. Actuator 199 may include one or more buttons, a handle, a mechanical deployment system, an electro-mechanical deployment system, a lever, or a slide, all configured to move the tube between the retracted and deployed position.
At least part of the tube 113 is offset relative to or disposed proximate the first and second jaw 110, 120 members and is configured to apply suction to the area proximate the first and second jaw members 110, 120. Tube 113 may be disposed underneath/above (radially offset) relative to one or both of the jaw members 110, 120. Alternatively, tube 113 may be disposed in any other suitable manner, such as, but not limited to, within a jaw member 120.
As shown in
A suction valve, suction activator, or the like (not shown) may be included on or integrated with the housing 20 such that activation of a suction flow through tube 113 may be easily effected by a user by using, e.g., a handswitch. In some embodiments, the suction activator may be separate from the housing 20, such as a footswitch. In some embodiments, the actuator 199, as described above, also acts as a suction valve or the like such that when the actuator 199 is moved from the un-actuated position (
While the actuator 199 is shown to operate in a parallel linear fashion along with tube 113, the actuator 199 may be configured in any desired mechanical format to accommodate a desired ergonomic instrument layout to facilitate activation.
Referring now to the embodiment of
A ratchet assembly 30′ may be included for selectively locking the jaw members 110 and 120 relative to one another at various positions during pivoting. Ratchet assembly 30′ may include graduations or other visual markings that enable the user to easily and quickly ascertain and control the amount of closure force desired between the jaw members 110 and 120.
With continued reference to
Forceps 10′ includes a suction system disposed proximate the first and second jaw members and configured to apply suction to an area proximate the first and second jaw members. The suction system includes a tube 113′, similar to tube 113 as described above, that is connected to a suction source “L” as described herein. Tube 113′ may be slidably disposed within at least one of the shaft members 12a, 12b and selectively extendable from an opening defined proximally of the end effector 100. Tube 113′ may also be connected to an actuator 199′, similar to actuator 199 as described above, such that movement of actuator 199′ between an un-actuated position and an actuated position causes movement of tube 113′ between the retracted position and the deployed position.
Further disclosed is a method for performing a surgical procedure including the steps of providing a vessel sealing device such as forceps 10, open forceps 10′, or other medical instrument having two opposable jaw members operably connected to a shaft, at least one of the jaw members configured to move relative to the other between an open position and a clamped position A suction system is included proximate one or both of the jaw members.
Referring now to
As described herein, the tube 113 may be slidably disposed in forceps 10, and the method may also include the step of deploying the tube 113 from the retracted position to the deployed position to remove fluid and debris from the surgical site. The method may also include the step of retracting the tube 113 after use.
The various embodiments disclosed herein may also be configured to work with robotic surgical systems and what is commonly referred to as “Telesurgery”. Such systems employ various robotic elements to assist the surgeon in the operating room and allow remote operation (or partial remote operation) of surgical instrumentation. Various robotic arms, gears, cams, pulleys, electric and mechanical motors, etc. may be employed for this purpose and may be designed with a robotic surgical system to assist the surgeon during the course of an operation or treatment. Such robotic systems may include remotely steerable systems, automatically flexible surgical systems, remotely flexible surgical systems, remotely articulating surgical systems, wireless surgical systems, modular or selectively configurable remotely operated surgical systems, etc.
The robotic surgical systems may be employed with one or more consoles that are next to the operating theater or located in a remote location. In this instance, one team of surgeons or nurses may prep the patient for surgery and configure the robotic surgical system with one or more of the instruments disclosed herein while another surgeon (or group of surgeons) remotely controls the instruments via the robotic surgical system. As can be appreciated, a highly skilled surgeon may perform multiple operations in multiple locations without leaving his/her remote console which can be both economically advantageous and a benefit to the patient or a series of patients.
The robotic arms of the surgical system are typically coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the working ends of the herein described forceps (e.g., end effectors, suction systems, knifes, etc.) which may complement the use of one or more of the embodiments described herein. The movement of the master handles may be scaled so that the working ends have a corresponding movement that is different, smaller, or larger, than the movement performed by the operating hands of the surgeon. The scale factor or gearing ratio may be adjustable so that the operator can control the resolution of the working ends of the surgical instrument(s).
The master handles may include various sensors to provide feedback to the surgeon relating to various tissue parameters or conditions, e.g., tissue resistance due to manipulation, cutting or otherwise treating, pressure by the instrument onto the tissue, tissue temperature, tissue impedance, suction strength/pressure drop, etc. As can be appreciated, such sensors provide the surgeon with enhanced tactile feedback simulating actual operating conditions. The master handles may also include a variety of different actuators for delicate tissue manipulation or treatment further enhancing the surgeon's ability to mimic actual operating conditions.
It should be understood that the foregoing description is only illustrative of the present disclosure. Various alternatives and modifications can be devised by those skilled in the art without departing from the disclosure. Accordingly, the present disclosure is intended to embrace all such alternatives, modifications, and variances. The embodiments described with reference to the attached drawings are presented only to demonstrate certain examples of the disclosure. Other elements, steps, methods, and techniques that are insubstantially different from those described above and/or in the appended claims are also intended to be within the scope of the disclosure.
