BACKGROUNDIn some settings, endoscopic surgical instruments may be preferred over traditional open surgical devices since a smaller incision may reduce the post-operative recovery time and complications. Consequently, some endoscopic surgical instruments may be suitable for placement of a distal end effector at a desired surgical site through a cannula of a trocar. These distal end effectors may engage tissue in a number of ways to achieve a diagnostic or therapeutic effect (e.g., endocutter, grasper, cutter, stapler, clip applier, access device, drug/gene therapy delivery device, and energy delivery device using ultrasound, RF, laser, etc.). Endoscopic surgical instruments may include a shaft between the end effector and a handle portion, which is manipulated by the clinician. Such a shaft may enable insertion to a desired depth and rotation about the longitudinal axis of the shaft, thereby facilitating positioning of the end effector within the patient.
Examples of endoscopic surgical instruments include those disclosed in U.S. Pat. Pub.

II. Exemplary Surgical Instrument with Multiple Transmission Assemblies
As noted above, transmission assembly (70, 200) may be provided as a disposable or otherwise replaceable assembly, thereby allowing surgical instrument (50) to be used many times by replacing transmission assembly (70, 200) between uses. In addition or in the alternative, it may be simply desirable to keep transmission assembly (70, 200) separate from surgical instrument (50) when surgical instrument (50) is not in use such that surgical instrument (50) and transmission assembly (70) may be stored separately. Furthermore, a user may wish to select from different transmission assemblies (70, 200) having different features, configurations, and/or operabilities depending on the particular context. For example, one transmission assembly (70, 200) may be equipped with a motorized stapler whereas another transmission assembly (70, 200) may be equipped with an RF end effector. In fact, several different transmission assemblies (70, 200) having vastly different functions may be used. It will be appreciated that it may be desirable to have a single handle assembly (60) capable of handling various different transmission assemblies (70, 200) such that multiple different handle assemblies (60) do not have to be used.
For example,
As shown in
As can be seen in the above exemplary versions, transmission assemblies (300, 400, 500, 600) are operable to work in different modalities where each of transmission assemblies (300, 400, 500, 600) may require different instructions for proper operation. Generator (704) may be integrated with a programmable chip such that generator (704) may store information regarding the operation of transmission assemblies (300, 400, 500, 600). Each transmission assembly (300, 400, 500, 600) may comprise, for example, an identifier such that when transmission assembly (300, 400, 500, 600) and connector port (702) establish communication, generator (704) may be able to determine the type of transmission assembly (300, 400, 500, 600) attached. Thereafter, generator (704) can use instructions stored in the programmable chip to properly operate transmission assembly (300, 400, 500, 600) according to the specific modality of transmission assembly (300, 400, 500, 600) attached.
In yet other exemplary versions, connector port (702) may be operable to detect the identity of transmission assembly (300, 400, 500, 600) attached without transmission assembly (300, 400, 500, 600) having to directly identify itself to connector port (702). For example, connector port (704) may be configured to detect the impedance, number of connection contacts, etc., or any other suitable feature to determine which transmission assembly (300, 400, 500, 600) is connected to connector port (702).
It will be understood that in some exemplary versions, generator (704) and other components of handle assembly (700) do not necessarily need to contain any sort of processor or computing component. Such components may, in some versions, reside entirely in transmission assembly (300, 400, 500, 600). As a result, it will be appreciated that updated firmware may be stored and shipped with transmission assembly (300, 400, 500, 600), thereby allowing transmission assembly (300, 400, 500, 600) to have the latest version of any software for use with handle assembly (700). In some versions, generator (704) simply provides power to transmission assembly (300, 400, 500, 600) and/or merely follows instructions from transmission assembly (300, 400, 500, 600).
In some exemplary versions, it will be appreciated that the only connections between connectors may consist of electrical connections for providing power to an end effector of transmission assembly (300, 400, 500, 600) as well as a force transfer mechanism operable to engage and control any mechanically moving parts of transmission assembly (300, 400, 500, 600). It will be appreciated that such a configuration will allow for a simpler construction of transmission assembly (300, 400, 500, 600), which may be shipped separately from handle assembly (700). In yet other exemplary versions, it will be appreciated that any suitable portion of the electronics may be controlled from transmission assembly (300, 400, 500, 600) wherein another suitable portion of the electronics may be controlled from handle assembly (700). As a result, the number of electronic components may be divided between handle assembly (700) and transmission assembly (300, 400, 500, 600) in any suitable manner as would be apparent to one of ordinary skill in the art in view of the teachings herein.
Also depicted is an ultrasonic transmission assembly (1010), which is operable to deliver ultrasonic signal to a surgical site. Ultrasonic transmission assembly (1010) comprises a memory module (1020) and end effector (1010). Memory module (1020) contains instructions for operating transmission assembly (1010). Thus, as with RF transmission assembly (900) as discussed above, it will be appreciated that once ultrasonic transmission assembly (1000) is connected to connector port (802), memory module (1020) transfers instructions to processor (804) of handle assembly (800) operable to operate ultrasonic transmission assembly (1000) in the ultrasonic modality. As a result, it will be appreciated that a single handle assembly (800) may be operable for use with both ultrasonic transmission assembly (1000) and RF transmission assembly (900).
In some versions, external module (1106) may comprise an electrosurgical generator operable to supply power in the monopolar setting such that the grounding pad would be in communication with the electrosurgical generator. Furthermore in a monopolar setting, the disconnection of transmission assembly (1108) with negative post (1112) may occur mechanically and/or electrically. For example, in a mechanical disconnection, connecting a monopolar electrode may push transmission assembly (1108) slightly forward, causing negative post (1112) to disengage from negative contact (1110). In an electrical disconnection, the polarity of transmission assembly (1108) may be detected using a sensor, RFID, chip, or other means, and circuit between negative post (1112) and negative contact (1110) may be opened in response to detection that a monopolar generator is activated. In some such versions, a switch may be used to perform the disconnection. Other suitable ways in which negative post (1112) may be mechanically and/or electrically decoupled from negative contact (1110) and/or other components will be apparent to those of ordinary skill in the art in view of the teachings herein.
It will be appreciated that in any of the above-described transmission assemblies and handle assemblies, it may be desirable to determine the identity of the transmission assembly for: identification of the modality, the polarity, and/or other characteristics associated with the transmission assembly.
In some versions, identification device (1212) may comprise one or more interrupted rings such that a revolution of transmission assembly (1210) within handle assembly (1200) may result in a discrete number of contacts with contacts (1214) of controller board (1216) in a particular pattern indicative of the modality, etc. of transmission assembly (1210). As a result, controller board (1216) may also be operable to deduce the identity of transmission assembly (1210) by the number of interruptions caused by transmission assembly (1210) during a revolution of transmission assembly (1210). For example, if during the course of one revolution, identification device (1212) engages contacts (1214) four times, then it may be indicative of transmission assembly (1210) operating in the RF modality. In some versions, identification device (1212) may include conductive rings, grooves, reed switches, magnets, and/or protruding rings that are different based on the modality of transmission assembly (1210) such that when contacts (1214) engage identification device (1212), contacts (1214) communicate to controller board (1216) information regarding the identity and/or modality of transmission assembly (1210). In addition to the conductive rings, grooves, reed switches, magnets, and/or protruding rings merely touching contacts (1214), it will be appreciated that in some versions, conductive rings, grooves, reed switches, magnets, and/or protruding rings may be operable to engage switches analogous to how a key engages tumblers in a lock, thereby closing circuits in controller board (1216), which can be used to determine the identity of transmission assembly (1210). In the present example, the conductive rings, grooves, reed switches, magnets, and/or protruding rings are located on the side of identification device (1212), but it will be appreciated that conductive rings, grooves, reed switches, magnets, and/or protruding rings may be located on the proximal face of identification device (1212) as well.
It will also be appreciated that reconstruction filter (1400) is operable to allow control of the phase of output signal of amplifier (1300) to be maintained such that the output signal remains agile/flexible without undue delay between any instructions regarding changing phase in relation to when any phase change may eventually take effect. For example, reconstruction filter (1400) may utilize variable capacitors and/or variable inductors or other means to change the circuit elements such that the user may control the phase output of filter (1400) as well as, or in the alternative, control the width of filter (1400). It will further be appreciated that the pulse width modulation supplied to filter (1400) is sufficiently high such that the phase of the output of filter (1400) may be modified without compromising the sinusoidal output of filter (1400). Furthermore, it will also be appreciated that the timing of the pulse width modulation need not be uniform. In some versions, the pulse width modulation may be sinusoidally spaced in such a way so as to control the output amplitude of filter (1400).
It will be appreciated that amplifier (1300) enables the use of batteries to drive ultrasonic and/or RF end effectors without requiring unduly large electrical components that might otherwise be required for handling the delivery of power to an ultrasonic device, an RF based device, and/or a DC utilizing device. In other exemplary versions, any suitable power source (AC or DC) may be used as an input for amplifier. It will also be appreciated that during the operation of amplifier (1300), transistors contained in amplifier (1300) remain continuously or nearly continuously in saturation such that very little voltage is dropped across any connected devices when devices are connected to or removed from communication with amplifier (1300).
In some versions, a feedback loop may be used to produce a more desirable output of amplifier (1300). In particular, a feedback system may be in communication with amplifier (1300) for determining what may be required to compensate for non-linearity in the output of amplifier (1300). Accordingly, the drive waveform input to amplifier (1300) may be selectively pre-distorted in such a way that is operable to eliminate undesirable behavior in amplifier (1300) as determined by the feedback system. Furthermore, the drive waveform input may also be selectively pre-distorted to compensate for known or unknown non-linearity in the output of amplifier (1300). In some versions, the output voltage of amplifier (1300) may be monitored and analyzed in between applications of power, thereby allowing the user to determine the state of the electro-mechanical system associated with amplifier (1300) or the surgical instrument in communication with amplifier (1300). As a result of analyzing the voltage response, the input signal for amplifier (1300) may be pre-distorted or modified to compensate for or eliminate undesirable voltage behavior.
