The invention has been particularly developed for a controlled embolisation application in arterial and venous embolisation, and relates to a device used for halting the progression of aneurysm and reflux closing/aneurysms, blocking/arteries closing/arteriovenous malformations/-venous reflux procedures.

Methods and systems for instrument tracking and navigation are described. In one embodiment, the system may be configured to receive position sensor data from at least one position sensor tracking an instrument positioned within a luminal network and determine a position sensor-based estimated state derived from the sensor data. The system may be configured to determine a combined estimated state for the instrument based on the position sensor data and at least one other type of position data. The system may be configured to determine a location transform based on the combined estimated state and the position sensor-based estimated state and output an estimated state of the instrument based on the position sensor-based estimated state adjusted by the location transform.

An object sizing system sizes an object positioned within a patient. The object sizing system identifies a presence of the object. The object sizing system navigates an elongate body of an instrument to a position proximal to the object within the patient. An imaging sensor coupled to the elongate body captures one or more sequential images of the object. The instrument may be further moved around within the patient to capture additional images at different positions/orientations relative to the object. The object sizing system also acquires robot data and/or EM data associated with the positions and orientations of the elongate body. The object sizing system analyzes the captured images based on the acquired robot data to estimate a size of the object.

Systems, devices and methods are provided in which an instrument can translate along an insertion axis. Rather than relying primarily on a robotic arm for instrument insertion, the instruments described herein have novel instrument based insertion architectures that allow portions of the instruments themselves to translate along an insertion axis. For example, an instrument can comprise a shaft, an end effector on a distal end of the shaft, and a handle coupled to the shaft. The architecture of the instrument allows the shaft to translate relative to the handle along an axis of insertion. The translation of the shaft does not interfere with other functions of the instrument, such as end effector actuation.

A surgical system (200) includes a surgical instrument (260) that is sensitive to backlash that would adversely affect the transmission of controlled torque and position to the surgical instrument. The surgical instrument (260) is coupled to motors in a surgical instrument manipulator assembly (240) via a mechanical interface. The combination of the mechanical interface and surgical instrument manipulator assembly (240) have low backlash, e.g., less than 0.7 degrees. The backlash is controlled in the surgical instrument manipulator assembly (240). From the drive output disk (545) in the surgical instrument manipulator assembly to the driven disk (964) of the surgical instrument, the mechanical interface has zero backlash for torque levels used in surgical procedures.

Various exemplary systems, devices, and methods are provided for locking articulating surgical tools. In general, a surgical tool can include an elongate shaft having at a distal end thereof an end effector configured to engage tissue. The end effector can be configured to articulate relative to the elongate shaft. The surgical tool can include a locking mechanism configured to lock the end effector at its current angled orientation. The surgical tool can be configured to releasably couple to a robotic surgical system configured to control a variety of movements and actions associated with the surgical tool.

A device for insertion into a vessel and suitable for implementing translational movement through the vessel includes a flexible tube containing a translational actuator. Anchoring actuators are positioned along the length of the flexible tube and are configured to controllably expand against the inner wall of the vessel in coordination with extension and contraction of the translational actuator to effect translational movement.

The disclosure relates to a robotic arm for use in surgery, microsurgery or supermicrosurgery, in particular for anastomosis, comprising: at least one instrument module comprising an instrument actuation submodule, wherein the instrument actuation submodule is configured to operate grasp and roll orientation of an instrument, wherein the instrument actuation submodule comprises a first motor and a first drivetrain for actuation of the instrument roll orientation, and wherein the instrument actuation submodule comprises a second motor and a second drivetrain for actuation of the instrument grasp orientation, at least one pitch module, and at least one yaw module.

A surgical instrument includes an end effector, a shaft assembly, an actuation driver, and an actuation assembly. The end effector includes first and second jaws. At least one of the first and second jaws is configured to move relative to the other of the first and second jaws to compress tissue therebetween. The shaft assembly extends proximally from the end effector. The shaft assembly includes a closure member extending along a longitudinal axis. The actuation driver is configured to configured to receive a motor output from a motor. The actuation assembly is operatively coupled with the actuation driver and the closure member. The actuation assembly includes a translating member configured to translate together with the closure member along the longitudinal axis a predetermined distance using the actuation driver such that the closure member applies a predetermined closure force to the first and second jaws corresponding to the predetermined distance.

A medical apparatus includes a base unit including a drive source therein, and a bendable unit that is to be detachably attached to the base unit. The bendable unit includes a connection unit including a first member connected to the drive source and a second member connected to a linear member. In a case where pulling force at a first threshold value or less or compression force at a second threshold value or less acts between the first member and the second member, the connection unit maintains a state in which the first member and the second member are connected, and in a case where pulling force exceeding the first threshold value or compression force exceeding the second threshold value acts between the first member and the second member, the connection unit separates the first member and the second member from each other.
