A cranial drill guide includes a housing and a drill guide sleeve assembly pivotally attached to the housing. The drill guide sleeve assembly has at least two degrees of freedom to allow the drill guide sleeve assembly to be moved to a first pivoted position for forming an angled burr hole through a cranial surface. The two degrees of freedom can comprise a pivoting motion of the drill guide sleeve assembly and an axial motion of a portion of the drill guide sleeve assembly.

A medical holding system and method are disclosed herein. The medical holding system, in an embodiment, includes a holder and a support device. The holder includes a grasper configured to be coupled to an end of an implantable element. The holder also includes a coupler having a coupler portion. The support device includes a release interface. The holder and the support device are configured to keep the implantable element suspended above a support surface throughout engagement and disengagement conditions of the coupler portion.

A disclosed medical observation system includes a capturing unit operable to capture an image of an observation target; and a light projection unit operable to project light on the observation target, outside a capturing area that is captured by the capturing unit and in a periphery of the capturing area, the light enabling recognition of a capturing state of the capturing unit.

The application describes an adjustable arm for a patient monitoring device to be placed on a surface portion of a patient's body, said arm comprising: at least first and second arm parts; abase to which the first arm part is connected and which includes mounting means for mounting it relative to a patient support platform; and holding means for receiving the patient monitoring device, to which the second arm part is connected; the arm parts, the base and the holding means being articulated by means of joints therebetween, which joints are fixable against movement when the patient monitoring device is in use; wherein the joints between the first arm part and the base and between second arm part and the holding means comprise multidirectional joints; wherein the base has a fixed portion and a tillable portion, the fixed portion comprising the mounting means and the first arm part being connected to the tillable portion, whereby when the said joints are fixed the adjustable arm can maintain the patient monitoring device in position on the patient surface portion while allowing for movement of the patient monitoring device due to respiration.

To realize torque control based on an estimated external force and to cope with more various situations. Provided is a medical support arm system including: a support arm that is a multilink structure having a plurality of links connected by a joint unit including an actuator, and configured to support a medical unit; and a control device including an external force estimation unit configured to estimate an external force acting on the joint unit on the basis of a drive characteristic of the actuator, and a joint control unit configured to control drive of the joint unit on the basis of an external torque estimated by the external force estimation unit.

A robot arm and method for using the robot arm. Embodiments may be directed to an apparatus comprising: a robot arm; an end effector coupled at a distal end of the robot arm and configured to hold a surgical tool; a plurality of motors operable to move the robot arm; and an activation assembly operable to send a move signal allowing an operator to move the robot arm.

A stabilizing apparatus for a transcatheter delivery system includes a housing having an aperture to receive the transcatheter delivery system. An engagement member is disposed in the housing. A biasing element urges the engagement member against a surface of the transcatheter delivery system when the transcatheter delivery system is placed in the housing.

Selectively lockable holding arrangements for a surgical access assembly are disclosed. One holding arrangement includes a body portion, an engagement barrel and a retaining member configured as a hook at a distal end of the body portion. The engagement barrel is position on a proximal end of the body portion and is configured to be selectively rotated about the body portion when operatively connected to a surgical holding arrangement. A rotation brake is mounted on the body section. The rotation brake is selectively operable to lock the engagement barrel against rotation.

A medical observation system includes: a microscope; a support including a first joint configured to hold the microscope such that the microscope is rotatable about a first axis parallel to an optical axis of the microscope; and a first arm configured to hold the first joint and extend in a direction different from a direction of the optical axis of the microscope; a light guide cable inserted in the support and configured to guide illumination light to the microscope; and a binder configured to bind the light guide cable, wherein at least a part of the light guide cable is arranged along the first axis in a first section, the light guide cable extends in a direction different from the first axis in a second section, and the binder is configured to bind the light guide cable in the second section.
