Abstract:
Battery corrosive electrolyte leak is reduced by using spacers (which can be made of a shock absorbing material) between each pair of three or more batteries held in a series configuration so that a resilient contact provides an electrical contact between the pair of batteries and the thickness of the spacer prevents a second end of a first battery from contacting the first end of the second battery.
Abstract:
A surgical instrument can comprise a handle including a battery cavity and electrical contacts and, in addition, a battery removably positionable in the battery cavity. The battery is configured to engage and supply power to the electrical contacts when the battery is operably seated in the battery cavity. The handle further comprises diagnostic means for assessing whether the handle is in a suitable operating and a battery lockout configured to permit the battery from being operably seated in the battery cavity if the diagnostic means determines that the handle is not in a suitable operating condition. Additionally or alternatively, the handle can comprise a battery lock configured to prevent the battery from being disengaged from the electrical contacts when the handle is transmitting an operating motion to a shaft assembly attached to the handle, for example. Either one system or two systems can comprise the battery lockout and battery lock.
Abstract:
Die Erfindung beschreibt einen Akkupack (100) für eine Handwerkzeugmaschine (300), aufweisend einen Zellenhalter (600) und mindestens eine Akkuzelle (400), wobei der Zellenhalter (600) die mindestens eine Akkuzelle (400) aufnimmt, wobei die Akkuzelle (400) eine zu einer Längsachse (x) parallel verlaufende Mantelfläche (405) aufweist, wobei die Mantelfläche (405) von zwei senkrecht zu der Längsachse (x) stehenden Stirnflächen (410) begrenzt wird, an denen sich die elektrischen Pole der Akkuzelle befinden. Zwischen wenigstens einer Stirnfläche (410) der Akkuzelle (400) und einer im Wesentlichen parallel zu der Stirnfläche (410) der Akkuzelle (400) verlaufenden Wandung des Akkupackgehäuses (110) ist wenigstens eine elastische, wärmeleitende Einlage (650) angeordnet, wobei die elastische, wärmeleitende Einlage (650) in thermischem Kontakt mit der Stirnfläche (410) der Akkuzelle (400) steht und Wärme von der Akkuzelle (400) in Richtung der Wandung des Akkupackgehäuses (110) abführt.
Abstract:
An apparatus is disclosed which comprises, one, a handle module that is attachable to a detachable shaft module for collectively performing a surgical procedure and, two, an inspection station for connection to the handle module when the handle module is not being used in a surgical procedure. The handle module comprises a rotary drive system for driving the detachable shaft module, an electric motor coupled to the rotary drive system for powering the rotary drive system, and a handle module processor circuit in communication with the motor. The inspection station comprises an inspection station processor circuit that communicates with the handle module processor circuit via a data connection when the handle module is connected to the inspection station. The inspection station further comprises a display in communication with the inspection station processor circuit for displaying information about handle module.
Abstract:
Embodiments of systems and methods for inductively powering seismic sensor nodes are presented. An embodiment of an inductive battery includes a battery cell configured to store charge for use by an external device. The inductive battery may also include a first inductive element coupled to the battery cell, the first inductive element configured to receive current from the battery cell and emit a responsive magnetic field for powering an external device through inductance. In an embodiment the external device is a seismic sensor node.
Abstract:
A battery holder for use with a battery-powered sensor may be configured such that removing the battery involves at least two distinct motions. The battery holder may include a cradle and a resilient retention strap configured to be deflectable between relaxed and deflected positions. With the retention strap in the relaxed position, the cradle and the retention strap may cooperate to retain the battery in the inserted position within the battery holder. The battery may be removed by first manipulating the retention strap from the relaxed position to the deflected position, and then using a distinct second motion to remove the battery from the holder. The battery holder may be configured to substantially prevent movement of the battery relative to the cradle when the battery is in the inserted position. The battery holder may be configured to facilitate insertion of the battery into the holder in a desired orientation.
Abstract:
Various electrical and slip ring connector arrangements configured to facilitate the passage of electrical current and signals between two components that are rotatable relative to each other such as an interchangeable surgical shaft assembly that includes portions that are rotatable relative to fixed mounting portions.
Abstract:
An interchangeable shaft assembly for a surgical instrument that includes first and second drive systems. The interchangeable shaft assembly is configured for removable attachment to a housing of the surgical instrument. Various embodiments include a latch system that enables the interchangeable shaft assembly to be detached from the housing when the first drive system is unactuated but prevents the interchangeable shaft assembly from being detached from the housing when the first drive system is in an actuated position.
Abstract:
The present disclosure provides a surgical instrument including a handle assembly and an interchangeable shaft assembly. The shaft assembly includes an elongate shaft, and an end effector extending distally from the elongate shaft. The handle assembly includes a motor configured to effectuate at least one motion in the end effector while said handle assembly is coupled to the shaft assembly. A power assembly is separably couplable to the handle assembly. The power assembly includes a power source configured to power the motor and a power management controller in communication with the power source. The power management controller is configured to receive an input signal corresponding to at least one power requirement of the shaft assembly. The power management controller is configured to modulate power output of the power source to the motor to conform the power output with the at least one power requirement of the shaft assembly.
