This disclosure relates to kits for powered surgical instruments, and in particular, powered surgical instrument kits that cause a powered surgical instrument to perform a homing initiating procedure prior to use of the powered surgical instrument.
During laparoscopic or endoscopic surgical procedures, access to a surgical site is typically achieved through a small incision or through a narrow cannula inserted through a small entrance wound in a patient. Because of limited area to access the surgical site, many endoscopic surgical devices include mechanisms for articulating or rotating the tool assembly or the end effector of the device.
In surgical instruments that are used to apply tacks or anchors having helical threads, for example, an additional challenge exists when attempting to rotate the end effector, as the tacks are also configured to rotate through the end effector, through a surgical mesh, and into tissue, for instance. Some tack-applying surgical instruments include the ability for its end effector to articulate and rotate, while also limiting the overall amount of rotation to prevent the premature ejection of tacks and to prevent timing issues when attempting to eject tacks.
Some surgical instruments include a reusable handle that is usable with an attachable component, such as a tack cartridge that houses tacks. In such multi-component configurations, proper alignment of the interconnecting components ensures proper operation of the surgical instrument.
The disclosure relates to a kit for a powered surgical instrument. The kit includes a powered surgical instrument, a blister pack housing the powered surgical instrument, a component packaging housing an end effector configured to attach to the powered surgical instrument, and a non-conductive pull-tab connected to the powered surgical instrument and the component packaging. The powered surgical instrument includes a motor and a power source configured to power the motor and is configured to perform a homing initiation procedure upon a powering on thereof. The non-conductive pull-tab includes a proximal end electrically separating the motor of the powered surgical instrument from the power source configured to power the motor and a distal end coupled to a portion of the component packaging. The homing initiation procedure is commenced upon removal of the non-conductive pull-tab from between the motor and the power source to power on the powered surgical instrument.
In an aspect, the proximal end of the non-conductive pull-tab extends through a slit defined in a housing of the powered surgical instrument. The non-conductive pull-tab may be removably coupled to the powered surgical instrument and permanently coupled to the component packaging. In an aspect, the proximal end of the non-conductive pull-tab is disposed between a battery and a circuit coupled to the motor such that the non-conductive pull-tab prevents the formation of a circuit. Additionally, or alternatively, the distal end of the non-conductive pull-tab is coupled to the component packaging such that the end effector housed in the component packaging is incapable of being removed from the component packaging without removing the proximal end of the non-conductive pull-tab from the powered surgical instrument.
In an aspect, the powered surgical instrument is a tack applier.
In an aspect, the component packaging is positioned in the kit at least a distance from a distal end of the powered surgical instrument and a length of the non-conductive pull-tab is less than the distance such that the end effector housed in the component packaging is prevented from being able to be connected to the distal end of the powered surgical instrument without removing the proximal end of the non-conductive pull-tab from the powered surgical instrument.
In another aspect, a kit includes a powered surgical instrument, a blister pack housing the powered surgical instrument, a cover covering the blister pack and removable therefrom, and a non-conductive pull-tab connected to the powered surgical instrument and the cover. The powered surgical instrument includes a motor and a power source configured to power the motor and is configured to perform a homing initiation procedure upon a powering on thereof. The non-conductive pull-tab includes a proximal end electrically separating the motor of the powered surgical instrument from the power source configured to power the motor and a distal end coupled to a portion of the cover. The homing initiation procedure is commenced upon removal of the non-conductive pull-tab from between the motor and the power source to power on the powered surgical instrument.

The details of one or more aspects of the disclosure are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the techniques described in this disclosure will be apparent from the description and drawings, and from the claims.
Various aspects of the disclosure are described hereinbelow with reference to the drawings, which are incorporated and constitute a part of this specification, wherein:
In electrically powered laparoscopic surgical devices, there often is a need to perform a homing routine before a user operates the device. Prior to use, there may also be an operation where a user needs to add a consumable component/subassembly to the device prior to use, for example, a reload loading unit that is attachable to the shaft of the instrument. In such instances, the proper sequencing of events can help ensure the proper operation of the instrument and the firing of the components from the reload. For instance, if a reload is attached prior to homing, the device may not deliver the correct output or may be entirely inoperable.
Although homing routines are typically performed on the surgical devices prior to their packaging and shipment, it is possible that components of the device may move during shipment or handling of the packaged device. In such instances, the device would benefit from an additional homing routine prior to use. Users may not be aware of whether movement of components occurred during shipment and handling of the packed device, and therefore may not perform a homing routine on the device before operation thereof.
The packaging solutions (also referred to as kits), described herein solve the above-noted problem. In particular, the present packaging solutions prevent the operation of the device until a homing routine is performed. In battery powered laparoscopic surgical devices, a strip of non-conductive plastic may be used to separate the battery contacts from the positive and/or negative terminals of the battery. This breaks the circuit and insures the device is stable throughout its shelf life. As described in greater detail below, sizing of the non-conductive strip and placement relative to the surgical device and other components of a kit address the above-identified problems in that the connectable component is incapable of being connected to the surgical device until the homing routine is performed. In an aspect, the length of the plastic strip is substantially shorter than the distance required to install the reload. This forces the user to pull the strip, powering the device and allowing the homing routine to auto start prior to being able to install the reload on the device.
Embodiments of the presently disclosed kits are 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 “distal” refers to that portion of the endoscopic surgical device that is farther from the user, while the term “proximal” refers to that portion of the endoscopic surgical device that is closer to the user.

The loading unit 30 includes an outer tube 32 defining a lumen (not shown), a spiral or coil 36 fixedly disposed within the outer tube 32, and an inner tube 38 rotatably disposed within the coil 36. The inner tube 38 defines a lumen therethrough, and includes a first portion 38a and a splined second portion 38b. The second portion 38b of the inner tube 38 is slotted, defining a pair of tines 38b1 and a pair of channels 38b2. The second portion 38b of the inner tube 38 is configured to support the plurality of surgical tacks 10 within the inner tube 38. In particular, the surgical tacks 10 are loaded into the loading unit 30 such that the pair of opposing threaded sections 112a of the surgical tacks 10 extend through respective channels 38b2 of the second portion 38b of the inner tube 38 and are slidably disposed within the groove of the coil 36, and the pair of tines 38b1 of the second portion 38b of the inner tube 38 are disposed within the pair of slotted sections 116a of the surgical tack 10. In use, as the inner tube 38 is rotated about a longitudinal axis “X-X” thereof, relative to the coil 36, the pair of tines 38b1 of the inner tube 38 transmits the rotation to the surgical tacks 10 and advances the surgical tacks 10 distally as the head threads 114a of the surgical tacks 10 engage with the coil 36.

In use, the loading unit 30 is operatively mounted to a distal end of the elongate member 50. The loading unit 30 is introduced into a target surgical site while in the non-articulated condition. The clinician may remotely articulate loading unit 30 relative the longitudinal axis “X-X” to access the surgical site. Specifically, the clinician may slide the engaging portion 364 of the articulation lever 360 along the engaging surface 204 of the housing 202. As the articulation rod 310 is displaced axially, the loading unit 30 is moved to an articulated orientation relative to the central longitudinal axis “X-X”. Furthermore, the clinician may position the surgical mesh “M” adjacent the surgical site. Once the surgical mesh “M” is properly positioned on the surgical site, the clinician may trigger the actuation switch 404 to eject a surgical tack 10 through the mesh “M” and into tissue “T”. While the articulation rod 310 is configured for axial displacement, it is further contemplated that an actuation rod 1310 may be rotatably supported by a rotor 1370 such that the actuation rod 1310 outputs an axial rotation which may be utilized by the loading unit 30 to effect articulation thereof, as can be appreciated with reference to
