Various embodiments are directed to battery packs for use with surgical instruments. The battery packs may comprise a plurality of cells and at least a portion of the plurality of cells may not be electrically connected to one another. The battery packs may comprise a switch or other mechanism for interconnecting the plurality of cells and may also comprise, or be used in conjunction with, a discharge switch or plug configured to electrically connect an anode of the battery pack to a cathode of the battery pack, for example, via a resistive element.

An apparatus for delivering electrical power to an electrically powered medical device includes a battery, a first compartment, and a second compartment where the second compartment can hold the first compartment and the first compartment can hold the battery. A sterile space is defined between the first compartment and the second compartment. The first compartment and the battery may be selectively electrically coupled with the electrically powered medical device such that the first compartment does not compromise the sterility of the electrically powered medical device.

Tissue thickness compensators for use with circular surgical staplers. Various tissue thickness compensators are disclosed for deployment between a stapler head of a surgical circular stapler and an anvil attached thereto to accommodate variances in tissue thickness during stapling. Some tissue thickness compensator arrangements include means and configurations for deploying healing agents for enhancing the healing process.

A motor-driven surgical cutting and fastening instrument that comprises an end effector, a shaft connected to the end effector, and handle connected to the shaft. The end effector may comprise a cutting instrument that, when actuated, longitudinally traverses the end effector to cut tissue clamped in the end effector. The handle may comprise an electric motor for actuating the cutting instrument and a motor control circuit for controlling the motor. The motor control circuit may comprise a power source connected to the motor for electrically powering the motor and a current control circuit, connected to the power source, for varying the current supplied to the motor from the power source. The current control circuit may vary the current supplied to the motor, and consequently, the output torque supplied by the motor, such that the motor has at least (i) a first, low power operational mode for a first portion of a cutting stroke cycle of the cutting instrument, and (ii) a second, high power operational mode for a second portion the cutting stroke cycle of the cutting instrument.

An apparatus maintains the sterility of a medical device while providing for the insertion of an insertable component into the medical device. The apparatus includes a medical device having a housing sized to contain the insertable component, an active feature, a cap, and a hinge member. A container encases the medical device within a device recess, a cap recess, and a container cover. The insertable component may be inserted into the housing while limiting potential contact with the exterior of the medical device. An alternative assembly comprises an insertion assembly having a handle and the insertable component detachably attached thereto. The medical device comprises a housing, an active feature, and a flexible member. An insertion tube is insertable within the flexible member to limit contact when the insertable component is inserted into the housing. Yet another configuration includes a resiliently hinged door assembly releasable by a release button.

In various embodiments, a surgical test device for a surgical tool, such as a severing and/or sealing tool (e.g., a surgical stapler), is provided. In at least one embodiment, the surgical tool can be configured to supply at least one actuation motion to an end effector. The actuation motion(s) may cause a cutting member to move within and/or sealing members (e.g., staples) to eject from the end effector. Further, in at least one embodiment, the surgical test device can be releasably engaged to a portion of the surgical tool, such as the end effector. Additionally, the surgical test device can be configured to permit the surgical tool to supply the actuation motion(s) while preventing the tool from performing its intended surgical function. Accordingly, the surgical tool may be test fired without wasting a sealing member cartridge, while preventing inappropriate use of the tool when the test device is attached thereto.
摘要:
In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.
摘要:
An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. A tension release mechanism is associated with the tension element.
