A cannula insertion system for inserting a cannula into a human or animal body, includes a cannula and a cannula insertion device to hold and insert the cannula into the human or animal body in an insertion direction. The cannula insertion system includes a safety device configured to retract the cannula or to release the cannula from the cannula insertion device when a force exerted on the cannula in a direction perpendicular to the insertion direction results in exceeding a respective safety threshold value.

An electromechanical robotic arm is provided having a distal end with a tool engaging member configured to mate with an electromechanical tool and a trocar holding member configured to mate with a trocar. The trocar holding member can have at least one engagement mechanism configured to engage and orient a trocar to mate the trocar to the trocar holding member in a desired orientation.

The invention relates to a system for controlling with respect to a body of a patient, displacement of an intervention device having an end intended to be inserted in the body of the patient through a point of penetration, comprising: A base (10) intended to be in a fixed position relative to the patient; A first portion (20) comprising an arc member (21), said first portion (20) being pivotally mounted on the base (10) around a first axis (A1), wherein said first axis (A1) is parallel to an arc plane defined by the arc member (21); A second portion (30) comprising a support member (32) and a carrier member (31), said support member (32) having a longitudinal axis and said carrier member (31) being slidably mounted on the arc member (21) for partially rotating around a second axis (A2), said second axis (A2) extending through a centre of curvature of the arc member perpendicularly to the arc plane, wherein the second axis (A2) and the first axis (A1) are perpendicular; A third portion (40) comprising a holding member (41) for releasable attachment of the intervention device, and a sliding member (42) slidably mounted on the support member (32) along a translation axis (A.sub.T) being parallel to the arc plane and corresponding to the longitudinal axis of the support member (32), the holding member (41) being arranged relative to the sliding member (42) so that translation of the sliding member (42) along the translation axis (A.sub.T) causes the intervention device to translate along a third axis (A3), and
wherein the first (A1), second (A2) and third (A3) axes are concurrent, the third axis (A3) being parallel to and offset from the translation axis (A.sub.T), said offset being made along at least a first offset direction being perpendicular to the translation axis (A.sub.T) and parallel to the arc plane, so that when the carrier member (31) is positioned halfway of the arc member (21) then the first (A1), second (A2) and third (A3) axes are orthogonal.

The present invention teaches apparatuses, systems and methods for performing a variety of medical procedures, including those involving introducing one or more substances into a subject's body. In some embodiments, the invention teaches automatically performing guided injections into a tissue site (e.g. spinal cord) of a subject by using one or more electronically operated components including a cannula, a syringe pump, and a stereotactic device.

Tissue localization devices and methods of localizing tissue using tissue localization devices are disclosed. The tissue localization device can comprise a handle comprising a delivery control, a delivery needle extending out from the handle, and a localization element within the delivery needle. The localization element can be deployed out of the delivery needle or retracted back into the delivery needle when the delivery control is translated in a first direction or a second direction, respectively. The localization element can be coupled to a flexible tracking wire.

A surgical instrument is configured for coupling with an instrument drive unit that drives an actuation of the surgical instrument and operatively supports the surgical instrument. The surgical instrument includes a housing, an elongate body extending distally from the housing, an end effector extending distally from the elongate body, and a plurality of driven members rotatably disposed within the housing. The plurality of driven members is nested with one another. Each driven member of the plurality of driven members is coupled to a respective cable that is attached to the end effector. The plurality of driven members is configured for engagement with an instrument drive unit.

A surgical mounting device may detachably couple to a patient access device to maintain alignment between a surgical instrument and the access device as instruments are interchangeably inserted and removed from the access device. The mounting device may include arms that pivot between a closed configuration in which the arms grip the access device inserted therebetween and an open configuration in which arm are spaced further apart from each other than in the closed configuration. A drive member may transition the arms to the closed configuration when the patient access device is inserted between the arms in the open configuration and pressed against the drive member.

A device for selectively grasping a part of a separate elongated body extending through the device, includes at least three partially mobile jaw members defining between them a through hole of variable diameter depending on their mutual relative positioning, supporting and driving elements to which the jaw members are mounted and which are adapted to provide a coordinated motion to the members around the elongated body situated in the variable through hole, resulting in a closing or opening of the through hole. The jaw members have an elongated shape with two opposed ends and the supporting and driving elements include a circular or annular support body to which a first end of each jaw member is connected and a mobile annular driving body to which a second opposed end of each jaw member is connected.
