     BACKGROUND 
     1. Technical Field 
     The present disclosure relates to surgical instruments suitable for use in sterile environments and, more specifically, to surgical instruments having a non-sterile component encapsulated within a sterile membrane for use in a sterile environment. 
     2. Discussion of Related Art 
     After a surgical instrument has been manufactured and/or after a surgical instrument has been used during a surgical procedure, the surgical instrument can be subjected to physical sterilization and/or chemical sterilization in order to kill or eliminate transmissible agents. Physical sterilization can include gamma radiation sterilization which can be suitable in many circumstances. In some circumstances, however, gamma radiation can damage the components of the surgical instrument, in particular the electronic components thereof. As a result, the options available to sterilize such surgical instruments can be limited to heat or steam sterilization and/or chemical sterilization, such as ethylene oxide, ozone, and/or hydrogen peroxide, for example. While such options are suitable in many circumstances, these options may be more expensive, more time-consuming to perform, and/or unavailable at a particular facility. Further, components of the surgical instrument may degrade or be rendered inoperable after being subjected to one or more sterilizations.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure are now described in detail with reference to the drawings in which like reference numerals designate identical or corresponding elements in each of the several views. As used herein, the term “clinician” refers to a doctor, a nurse, or any other care provider and may include support personnel. Throughout this description, the term “proximal” will refer to the portion of the device or component thereof that is closest to the clinician and the term “distal” will refer to the portion of the device or component thereof that is furthest from the clinician. 
     Referring now to  FIGS. 1 and 2 ,  FIG. 1  depicts a portable, battery-powered electrosurgical instrument  2  and  FIG. 2  depicts a portable, battery-powered ultrasonic surgical instrument  102 . For the purposes herein, any electrosurgical instrument, e.g., instrument  2 ; ultrasonic instrument, e.g., instrument  102 ; or any other suitable battery-powered device, e.g., a surgical instrument, handheld tool, electronic device, or the like, may be utilized in accordance with the present disclosure. Obviously, different considerations apply to each particular type of device; however, the features and aspects of the present disclosure are equally applicable and remain generally consistent with respect to any suitable battery-powered device. For the purposes herein, electrosurgical instrument  2  and ultrasonic instrument  102  are generally described. 
     With reference to  FIG. 1 , electrosurgical instrument  2 , shown as an electrosurgical forceps, generally includes a housing  4 , a battery assembly  18 , an electrosurgical generator  28 , a handle assembly  6 , a rotating assembly  7 , a shaft  8 , a trigger assembly  10 , a drive assembly (not shown), and an end effector assembly  12 . End effector assembly  12  operatively connects to handle assembly  6  via the drive assembly (not shown) for imparting movement of one or both of jaw members  14 ,  16  of end effector assembly  12  between a spaced-apart position and an approximated position for grasping tissue therebetween. 
     Continuing with reference to  FIG. 1 , shaft  8  is coupled to housing  4  at proximal end  20  thereof and extends distally from housing  4  to define a longitudinal axis “A-A.” End effector assembly  12 , including jaw members  14  and  16 , is disposed at a distal end  22  of shaft  8 . End effector assembly  12  is shown configured as a unilateral assembly wherein jaw member  16  is fixed relative to shaft  8  and jaw member  14  is pivotable relative to jaw member  16  and shaft  8  between the spaced-apart and approximated positions. However, this configuration may be reversed, e.g., wherein jaw member  14  is fixed relative to shaft  8  and jaw member  16  is pivotable relative to jaw member  14  and shaft  8 . Alternatively, end effector assembly  12  may be configured as a bilateral assembly, e.g., wherein both jaw members  14 ,  16  are pivotable relative to one another and shaft  8  between the spaced-apart and approximated positions. 
     Electrosurgical instrument  2  may be configured as a bipolar instrument. That is, each of the jaw members  14 ,  16  may include a respective seal plate  15 ,  17  that is configured to function as an active (or activatable) and/or return electrode. Each seal plate  15 ,  17  is electrically coupled to generator  28  via one or more electrical leads (not shown) that extend from generator  28 , through shaft  8 , and eventually coupling to one or both of seal plates  15 ,  17  for conducting energy through tissue grasped therebetween. However, forceps  2  may alternatively be configured as a monopolar instrument. 
     Handle assembly  6  includes a moveable handle  40  that is movable relative to fixed handle portion  42  for moving jaw members  14 ,  16  of end effector assembly  12  between the spaced-apart and approximated positions. Rotating assembly  7  is rotatable in either direction about longitudinal axis “A-A” to rotate shaft  8  and, thus, end effector assembly  12  about longitudinal axis “A-A.” Trigger assembly  10  is in operable communication with a knife assembly (not shown) including a knife blade (not shown) that is selectively translatable between jaw members  14 ,  16  to cut tissue grasped therebetween, e.g., upon actuation of trigger  11  of trigger assembly  10 . 
     With continued reference to  FIG. 1 , housing  4  is configured to releasably engage both of the energy sources of instrument  2 , e.g., electrosurgical generator  28  and battery assembly  18 . Generator  28  is releasably engagable with body portion  44  of housing  4 , while battery assembly  18  is releasably engagable with fixed handle portion  42  of housing  4 . More specifically, battery assembly  18  is configured to engage fixed handle portion  42  of housing  4  such that battery assembly  18  functions as the stationary handle of housing  4  to facilitate grasping of the forceps  2 . Generator  28  releasably engages body portion  44  of housing  4  and may be selectively removable from body portion  44  either in connection with the removal of battery assembly  18  or independently. 
     When forceps  2  is assembled, generator  28  is disposed in operable electrical communication with battery assembly  18  to provide electrosurgical energy to end effector  12  for electrosurgically treating tissue, e.g., to seal tissue, although forceps  2  may alternatively be configured to deliver any other suitable form of energy to tissue, e.g., thermal energy, microwave energy, light energy, etc. With respect to electrosurgical tissue treatment, generator  28  may include suitable electronics that convert the electrical energy from battery assembly  18  into an RF energy waveform to energize one or both of jaw members  14 ,  16 . That is, generator  28  may be configured to transmit RF energy to seal plate  15  of jaw member  14  and/or seal plate  17  of jaw member  16  to conduct energy therebetween for treating tissue. An activation switch is disposed on housing  4  activatable for selectively enabling generator  28  to generate and subsequently transmit RF energy to seal plate  15  and/or seal plate  17  of jaw members  14 ,  16 , respectively, for treating tissue grasped therebetween. 
     Referring now to  FIG. 2 , ultrasonic instrument  102  includes components similar to that of electrosurgical instrument  2  shown in  FIG. 1 , namely, a housing  104 , a battery assembly  118 , an electrosurgical generator  128 , a handle assembly  106 , a shaft  108 , and an end effector assembly  112 . Accordingly, only the differences between ultrasonic instrument  102  and electrosurgical instrument  2  ( FIG. 1 ) will be described in detail below. 
     Housing  104  is configured to releasably engage ultrasonic generator  128  and battery assembly  118 . Shaft  108  extends distally from housing  104  to define longitudinal axis “B-B” and includes end effector assembly  112  disposed at distal end  122  thereof. One or both of jaw members  114  and  116  of end effector assembly  112  are movable relative to one another, e.g., upon actuation of moveable handle  124 , between an open position and a clamping position for grasping tissue therebetween. Further, one of the jaw members, e.g., jaw member  116 , serves as an active or oscillating ultrasonic blade that is selectively activatable to ultrasonically treat tissue grasped between jaw members  114 ,  116 . 
     Generator  128  includes a transducer (not shown) configured to convert electrical energy provided by battery assembly  118  into mechanical energy that produces motion at the end of a waveguide, e.g., at blade  116 . More specifically, the electronics (not explicitly shown) of the generator  128  convert the electrical energy provided by battery assembly  118  into a high voltage. AC waveform that drives the transducer (not shown). When the transducer (not shown) and the waveguide are driven at their resonant frequency, mechanical, e.g., ultrasonic, motion is produced at the active jaw member  116  for treating tissue grasped between jaw members  114 ,  116 . Further, an activation button  110  disposed on housing  104  is selectively activatable to operate instrument  102  in two modes of operation: a low-power mode of operation and a high-power mode of operation. 
     With reference to  FIGS. 3 and 4 , battery assembly  118  generally includes an outer housing  130 , a battery pack  150 , battery circuitry  159 , and a contact cap  180 . Battery assembly  18  of electrosurgical instrument  2  ( FIG. 1 ) may be configured similarly to battery assembly  118  and, thus, will not be described herein for purposes of brevity. 
     Outer housing  130  of battery assembly  118  is formed from first and second housing parts  132 ,  134  that cooperate to house battery pack  150  and battery circuitry  159 . Housing parts  132 ,  134  define cut-outs  133 ,  135 , respectively, that cooperate to form a window configured to retain contact cap  180 . Contact cap  180  is electrically coupled to battery circuitry  159 , which, in turn, is electrically coupled to battery pack  140 . Contact cap  180  includes electrical contacts  182  configured to provide an electrical interface between battery assembly  118 , e.g., battery pack  150  and battery circuitry  159 , and both the battery-powered device, e.g., electrosurgical instrument  2  ( FIG. 1 ) or ultrasonic instrument  102  ( FIG. 2 ), and a battery charging device (not shown) for transmitting energy and/or control signals therebetween. Battery pack  150  includes a plurality of battery cell assemblies  152   a ,  152   b ,  152   c ,  152   d , e.g., four ( 4 ) battery cell assemblies  152   a - 152   d , although greater or fewer battery cell assemblies  152   a - 152   d  are also contemplated.
