Also provided is a tissue retrieval defined by a region of the bag defining an opening; an exterior surface of the bag depending from the opening; and at least one porthole on the exterior of the bag, wherein at least one tube extends from the at least one porthole.

An apparatus for determining alignment between a source device and a target device includes the source device, the target device, and a processing system. The source device includes a first spatially variant field generator for generating a first spatially variant electric field, and a second spatially variant field generator for generating a second spatially variant electric field. The second spatially variant electric field is angularly offset with respect to the first spatially variant electric field. The target device includes a sensor configured to detect a first signal from the first spatially variant electric field and a second signal from the second spatially variant electric field. The processing system is configured to determine alignment between the first source device and the target device based on the first and second signals from the first and second spatially variant electric fields by the target device.

A tool for installing and/or removing a protective cover of an instrument includes a body portion having an open end and a closed end. The open end defines an interior passage that extends into the body portion along a longitudinal axis of the body portion toward the closed end of the body portion. The interior passage is configured to receive at least a portion of the protective cover in the interior passage. One or more members are connected to the body portion, and each of the one or more members includes a free end movable relative to the body portion. Systems and methods relate to tools for installing and/or removing protective covers of instruments.

A surgical device comprises an elongate shaft (12) which extends from a proximal end region to a distal end region thereof, the shaft (12) defining a first lumen (14) for receiving an elongate camera device therein, a second lumen (16) for receiving a tissue manipulation device therein, and a third lumen (18) for receiving a tissue retrieval device therein, the first, second and third lumens (14, 16, 18) extending from the proximal end region to the distal end region of the elongate shaft, and having respective open ends at the distal end region of the elongate shaft. The surgical device further comprises an elongate camera device which extends along the first lumen, a tissue manipulation device which extends along the second lumen, and a tissue retrieval device which extends along the third lumen.

Described herein are examples of orthopedic reamer heads for preparing a bone to receive an implant, as well as methods of assembling reamer heads. An illustrative example of a modular reamer head can include a body and a cutting system. The body can include a generally dome shape having an outer surface extending from an apex region to a base. The outer surface can have a recess including one or more arcuate channels that extend from the apex region towards the base of the dome. The cutting system can have one or more arcuate elements having cutting elements. One or more arcuate elements can extend from first end portions in the apex region towards second end portions proximate the base. At least a portion of the one or more arcuate elements can be located in the one or more arcuate channels to extend outward beyond the outer surface.

This disclosure relates generally to treatment programs utilizing expansion elements, such as those associated with occlusion and therapeutic agent delivery devices, systems, and methods. In some more specific examples, treatment programs include expansion-contraction cycles at a pre-selected frequency profile configured to treat a particular condition, such as calcification of an arterial conduit, for example.

The present application provides an endoscopic device having at least one shaft, which has at least one portion deflectable in at least one plane, and having at least one deflection mechanism, which is configured to deflect the deflectable portion and includes, arranged in series, at least one first connection member and at least one second connection member interacting for a deflection with the first connection member. The first connection member is formed at least partially from a first material, and the second connection member is formed at least partially from a second material, of which the elasticity differs from that of the first material.

A surgical fastener applier including a housing containing a compartment, an elongated member extending distally from the housing, first and second jaws and a firing mechanism positioned within the housing. The firing mechanism is movable between a first position and a second position to effect firing of fasteners into the tissue clamped between the first and second jaws. A cover on the housing is openable to access the compartment. A power pack is removably loadable into the compartment, the power pack having a motor and an engagement member removably engageable with the firing mechanism within the compartment when the power pack is loaded into the compartment to effect movement of the firing mechanism from the first position to the second firing position.

The present application provides a ligation release device, comprising: a handle (1), an operating component (2), a suction component (3), a release component (4) and an illumination component (5), wherein the illumination component (5) is arranged in the handle (1) and comprises a light source (51), a wire (52) and a control switch (53), and the control switch (53) is connected to the light source (51) by means of the wire (52). In practical applications, the light source (51) can be turned on by operating the control switch (53), thereby illuminating a ligation area at the distal end of the handle (1), eliminating shadow influence and facilitating the implementation of ligation operation. The ligation release device can improve the ease and accuracy of surgical operation without an external auxiliary apparatus.

A universal motor cartridge for a surgical instrument includes a reusable housing having a distal face and a bottom surface and configured to securely engage a disposable surgical instrument. Couplers disposed on the distal face are adapted to engage couplers disposed on the surgical instrument upon engagement of the housing. A plurality of electrical interfaces on the bottom surface are adapted to electrically engage corresponding electrical interfaces on the surgical instrument, such that, upon activation of each switch disposed on the surgical instrument, the corresponding electrical interface on the surgical instrument communicates with the corresponding electrical interface on the bottom surface of the housing, which, in turn, actuates the corresponding coupler to engage and actuate the respective coupler on the surgical instrument causing the surgical instrument to rotate/articulate a shaft, open/close a pair of jaw members, deform staples, move a knife or energize an end effector.
