The disclosure relates to surgical instruments such as, for example, surgical clip appliers. More particularly, the disclosure relates to surgical clip appliers capable of supplying energy, e.g. monopolar energy, to one or more surgical clip(s) for use as energy-delivery electrodes, e.g., before deployment of the clip(s), at one or more partially-deployed positions, after deployment of the clip(s), etc. Related methods are also provided.
Surgical clip appliers are used for a number of distinct and useful surgical procedures. Surgical clip appliers having various sizes (e.g., diameters) are configured to apply a variety of diverse surgical clips and are capable of applying single or multiple surgical clips during cavity surgical procedure. Such surgical clips are typically fabricated from a biocompatible material and are usually compressed over tissue. Once applied to tissue, the compressed surgical clip terminates the flow of fluid therethrough.
Monopolar instruments are often used to dissect and/or coagulate vessels by applying energy to the vessel.
The disclosure relates to a clip applier. The clip applier includes a handle, an elongated shaft, an end effector, at least one surgical clip, a trigger, and an actuation mechanism. The elongated shaft extends distally from the handle. The end effector is operably engaged to a distal portion of the elongated shaft, includes a longitudinal axis defined therethrough, and includes a first jaw member and a second jaw member. The at least one surgical clip is disposed within the elongated shaft and is selectively loadable between the first and second jaw members. The trigger is configured to selectively translate at least a portion of the first jaw member relative to the second jaw member upon actuation thereof in a direction that is parallel to the longitudinal axis. The actuation mechanism is adapted to connect to a source of electrosurgical energy and is configured to selectively transmit energy to one of the at least one surgical clip.
In disclosed embodiments, a distal portion of the first jaw member is movable relative to the second jaw member and relative to a proximal portion of the first jaw member to deform a surgical clip of the at least one surgical clip.
In aspects of the disclosure, the actuation mechanism is configured to transmit energy to a distal-most surgical clip of the at least one surgical clip. It is disclosed that the transmission of energy occurs during formation of the distal-most surgical clip, while the first jaw member is stationary relative to the second jaw member, while at least a portion of the first jaw member is longitudinally translating relative to the second jaw member via actuation of the trigger, while at least a portion of the first jaw member is distally translating relative to the second jaw member via actuation of the trigger, and/or when the distal-most surgical clip is engaging tissue.
It is further disclosed that actuation of the trigger is configured to cause at least a portion of the first jaw member to move relative to the second jaw member in a direction that is at a non-parallel angle relative to the longitudinal axis.
Additionally, it is disclosed that actuation of the trigger is configured to cause translation of the second jaw member relative to the elongated shaft in a direction that is parallel to the longitudinal axis.
The disclosure also relates to a method of treating tissue. The method includes translating at least a portion of a first jaw member of a clip applier relative to a second jaw member of the clip applier, while simultaneously moving a surgical clip from a first position where the surgical clip is in contact with the first jaw member and the second jaw member, to a second position where the surgical clip engages tissue and dislodges from the first and second jaw members, and energizing the surgical clip.
In aspects of the disclosure, the method also includes automatically moving a second surgical clip from a position proximally of the first position into the first position.
Additionally, embodiments of the method include translating at least a portion of the first jaw member relative to the second jaw member causes formation of the surgical clip.
Further, in embodiments of the method, energizing the surgical clip is performed during formation of the surgical clip, while the first jaw member is stationary relative to the second jaw member, while at least a portion of the first jaw member is longitudinally translating relative to the second jaw member, and/or while the surgical clip is engaging tissue.
Embodiments of the method also include moving at least a portion of the first jaw member relative to the second jaw member in a direction that is non-parallel relative to the longitudinal axis.
Aspects and features of the disclosed surgical clip applier are described in detail with reference to the drawing figures wherein like reference numerals identify similar or identical structural elements and:
Embodiments of the surgical clip applier will now be described in detail with reference to the drawing figures wherein like reference numerals identify similar or identical structural elements. 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 which is closer to the user and the term “distal” refers to the end of the apparatus which is farther away from the user.
As used herein, the term parallel is understood to include relative configurations that are substantially parallel up to about + or −10 degrees from true parallel.

With continued reference to
The various clips 300, 300a, 300b, 300c of the disclosure are able to be energized with electrosurgical energy to serve as, for example, a monopolar electrode, although bipolar configurations, e.g., wherein the clip 300, 300a, 300b, 300c serves as one pole and an electrically-conductive portion of the clip applier 10 (that is isolated from the clip) serves as the other pole. There are various ways in which the clips 300-300c of surgical clip applier 10 can be energized. The clips 300-300c may be energized through direct contact with a conductive portion of the surgical clip applier 10 for example, such as the feed bar 400 that advances the clips 300-300c. The clips 300-300c may also be energized through a different conductive portion of surgical clip applier 10, 10a that makes direct or indirect contact with at least one clip 300-300c. In these embodiments, the conductive portion(s) of the surgical clip applier 10 may be connected to a lead wire that extends between the elongated assembly 200 and an actuation mechanism (e.g., a button 105 (
In other embodiments, the clips 300-300c are energized by contacting a portion of the surgical clip applier 10 that is electrically coupled to a conductive portion thereof (that is in direct or indirect contact with at least one clip 300-300c) with an energized device (e.g., a monopolar pencil).
Thus, since the energizing of the clips 300-300c is performed selectively, energy can be supplied to the clips 300-300c to make the clips 300-300c function as a monopolar electrode before, during various stages of, or after actuation and/or formation of the clips 300-300c. For instance, the actuation mechanism may be configured to transmit energy to the distal-most surgical clip when the distal-most surgical clip engages (e.g., upon or substantially upon initial engagement with) tissue. In these embodiments, surgical clip applier 10 may include at least one sensor 170 that detects when tissue is engaged by a surgical clip (e.g., the distal-most surgical clip), for instance. While the sensor 170 is shown engaged with the end effector 250, the sensor 170 (and/or an additional sensor) may be engaged with a different portion of the clip applier 10, such that the handle assembly 100.
In embodiments, a distal-most of the clips 300-300c may be advanced to an extended, pre-formation position, e.g., as shown in
In additional or alternative embodiments, a distal-most one of the clips 300-300c may be partially formed such that the clip 300-300c is deformed to define a different-shaped electrode such as, for example, the hook-shaped electrode configurations of clip 300c illustrated in
In either of the above configurations, once energy-based tissue treatment, e.g., using the electrode portion of the clip 300-300c in a pre-deployed or partially-deployed position or positions, is complete, the clip 300-300c may be fully formed about a vessel to clamp and close the vessel (see, e.g.,
Surgical instruments such as the surgical clip appliers described 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 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 control 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 any type of surgical instrument (e.g., end effectors, graspers, knifes, scissors, 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, 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.

Each of the robot arms 1002, 1003 may include a plurality of members, which are connected through joints, and an attaching device 1009, 1011, to which may be attached, for example, a surgical tool “ST” supporting an end effector 1100, in accordance with any one of several embodiments disclosed herein, as will be described in greater detail below.
Robot arms 1002, 1003 may be driven by electric drives (not shown) that are connected to control device 1004. Control device 1004 (e.g., a computer) may be set up to activate the drives, in particular by means of a computer program, in such a way that robot arms 1002, 1003, their attaching devices 1009, 1011 and thus the surgical tool (including end effector 1100) execute a desired movement according to a movement defined by means of manual input devices 1007, 1008. Control device 1004 may also be set up in such a way that it regulates the movement of robot arms 1002, 1003 and/or of the drives.
Medical work station 1000 may be configured for use on a patient 1013 lying on a patient table 1012 to be treated in a minimally invasive manner by means of end effector 1100. Medical work station 1000 may also include more than two robot arms 1002, 1003, the additional robot arms likewise being connected to control device 1004 and being telemanipulatable by means of operating console 1005. A medical instrument or surgical tool (including an end effector 1100) may also be attached to the additional robot arm. Medical work station 1000 may include a database 1014, in particular coupled to with control device 1004, in which are stored, for example, pre-operative data from patient/living being 1013 and/or anatomical atlases.
Accordingly, various endoscopic assemblies, constructed in accordance with the principles of the disclosure, may be provided which are also capable of firing or forming or closing surgical clips of various sizes, materials, and configurations, across multiple platforms for multiple different manufactures. For example, while the configuration of jaw members 250a and 250b have been shown and described for use with a surgical clip applier, it is contemplated and within the scope of the disclosure that the configuration of jaw members 250a, 250b may be incorporated into other surgical instruments, such as, for example, and not limited to, surgical staplers, tack appliers, and the like.
It should be understood that the foregoing description is only illustrative of the disclosure. Various alternatives and modifications can be devised by those skilled in the art without departing from the disclosure. Accordingly, the disclosure is intended to embrace all such alternatives, modifications and variances. The embodiments described with reference to the attached drawing figures 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.
