Articulating surgical stapling apparatus with pivotable knife bar guide assembly
A surgical stapling apparatus includes a shaft assembly, an end effector secured to the shaft assembly, a firing assembly, and an articulation assembly. The firing assembly includes a drive beam and a flexible knife bar assembly that are selectively advanceable through the end effector for firing the end effector. The articulation assembly has an articulation link assembly and a pivotable bar guide assembly. The articulation link assembly is coupled to the end effector and actuatable to cause the end effector to articulate relative to the shaft assembly. The pivotable bar guide assembly supports the flexible knife bar assembly and includes a proximal guide assembly and a distal guide assembly that are pivotably coupled together. The proximal guide assembly is pivotably coupled to the shaft assembly. The distal guide assembly is pivotably coupled to the end effector.
Surgical buttress assemblies and techniques for surgical stapling
A loading unit for a surgical stapling apparatus includes an anvil assembly, a staple cartridge assembly, and a surgical buttress assembly associated with the anvil or the staple cartridge assembly. Each of the anvil and staple cartridge assemblies has a tissue facing surface defining a central longitudinal slot therethrough. The surgical buttress assembly includes a buttress material positioned on the tissue facing surface of the anvil or staple cartridge assembly and a buttress frame supporting the buttress material. The buttress frame is movable from an undeployed position in which the buttress frame retains the buttress material within the boundaries of the tissue facing surface of the anvil or staple cartridge assembly to a deployed position in which the buttress frame extends the buttress material laterally outwardly from the anvil or staple cartridge assembly.
END EFFECTORS, SURGICAL STAPLING DEVICES, AND METHODS OF USING SAME
An end effector for stapling and cutting an anatomical structure includes an anvil, a cartridge, and a blade. The anvil has an anvil face and a plurality of staple pockets positioned on the anvil face. The cartridge has a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples. Each of the plurality of staples comprises a first staple leg, a second staple leg, and a crown connecting the first and second staple legs and having a midpoint. Each of the plurality of staples comprises an open staple configuration and a closed staple configuration where a first portion of the first staple leg and a second portion of the second staple leg are bent relative to the crown such that the first portion of the first staple leg and the second portion of the second staple leg cross the midpoint of the crown.
INTELLIGENT HOLDING ARM FOR HEAD SURGERY, WITH TOUCH-SENSITIVE OPERATION
A holding arm for holding a surgical mechatronic assistance system or a surgical instrument is described. The holding arm includes a proximal end for attaching the holding arm to a base and a distal end for receiving the surgical mechatronic assistance system or the surgical instrument. The holding arm also includes a first arm segment connected to a first joint and a second arm segment connected to a second joint. The first joint and the second joint are releasable and lockable. The holding arm also includes a switch adapted to release both the first and second joints. The holding arm also includes a first contacting device with two contact elements arranged substantially opposite one another on the first arm segment. The first contacting device is adapted to release the first joint only when both of the two contact elements of the first contacting device are contacted.
SYSTEM AND METHOD FOR DETECTING A POSITION OF A GUIDE CATHETER SUPPORT
A catheter procedure system includes a base and a robotic mechanism having a longitudinal axis and being movable relative to the base along the longitudinal axis. The robotic mechanism includes a robotic drive base including at least one drive mechanism, a cassette operatively secured to the robotic drive base, a rigid guide coupled to the cassette and fixed relative to the robotic mechanism and a flexible track having a distal end, a proximal end and a plurality of reflective sections. At least a portion of the flexible track is disposed within the rigid guide. The robotic mechanism also includes a position detector mounted to the robotic drive base and positioned beneath the flexible track. The position detector is configured to detect light reflected off of the reflective sections of the flexible track and to determine the position of the distal end of the flexible track based on the detected reflected light.
SURGICAL CLIP APPLIER WITH PARALLEL CLOSURE JAWS
An end effector for a surgical clip applier includes a housing, jaws that include opposed first and second jaw members, each comprising an independent structure movable relative to the other, the first jaw member defining a first inner surface and the second jaw member defining a second inner surface opposite the first inner surface, and an actuation mechanism arranged within the housing and operable to move the jaws between open and closed positions. The actuation mechanism includes an actuation plate longitudinally movable within the housing, and a transition pin extending from the actuation plate and received within corresponding slots defined in each jaw member. Linear movement of the actuation plate drives the transition pin through the corresponding slots and thereby moves the jaws between the open and closed positions.
SYSTEMS, METHODS, APPARATUSES, AND COMPUTER-READABLE MEDIA FOR IMAGE MANAGEMENT IN IMAGE-GUIDED MEDICAL PROCEDURES
Presented herein are methods, systems, devices, and computer-readable media for image management in image-guided medical procedures. Some embodiments herein allow a physician to use multiple instruments for a surgery and simultaneously provide image-guidance data for those instruments. Various embodiments disclosed herein provide information to physicians about procedures they are performing, the devices (such as ablation needles, ultrasound transducers or probes, scalpels, cauterizers, etc.) they are using during the procedure, the relative emplacements or poses of these devices, prediction information for those devices, and other information. Some embodiments provide useful information about 3D data sets and allow the operator to control the presentation of regions of interest. Additionally, some embodiments provide for quick calibration of surgical instruments or attachments for surgical instruments.
ADVANCING A TOOTHED RACK OF A SURGICAL HANDLE ASSEMBLY
The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a toothed rack, a movable handle member, a driving pawl configured to engage the toothed rack and advance the toothed rack in a linear distal direction in response to a movable handle member advancing in a proximal direction and a latch configured to engage the toothed rack and advance the toothed rack in a linear proximal direction in response to the movable handle member advancing in a distal direction.
PASSIVE PRELOAD AND CAPSTAN DRIVE FOR SURGICAL INSTRUMENTS
A system comprises a medical instrument including a rotatable capstan. The rotatable capstan includes a first coupling feature and a drive system including a rotatable drive element. The rotatable drive element includes a second coupling feature. The first and second coupling features have an aligned engagement configuration in which rotation of the rotatable drive element induces rotation of the rotatable capstan and a non-aligned engagement configuration in which rotation of the rotatable drive element does not induce rotation of the rotatable capstan.
INSTRUMENT COUPLING INTERFACES AND RELATED METHODS
A coupling and related methods are disclosed herein that can provide for coupling a first object and a second object with minimal play. A coupling can include a first coupling component having a cylindrical surface with a screw and a pin extending therefrom and a second coupling component having a prismatic surface with a first and a second through-hole. The first coupling component and the second coupling component can be configured such that relative motion between the first coupling component and the second coupling component can be restricted in all six degrees of freedom when the screw is engaged with the first through-hole to secure the cylindrical surface of the first component against the prismatic surface of the second component. The pin can be configured to maintain stability of the coupling and further limit relative movement, such that positioning and/or orientation errors between the first and second components is minimized.
