A sensor film comprising: a substrate core having a first surface and a second surface; at least one sensing element for sensing at least one property; a first conductive layer residing on the first surface, the first conductive layer having first solder mask coated thereon, and wherein the first conductive layer is grounded; and a second conductive layer residing on the second surface, the second conductive layer having a second solder mask coated thereon, and coupled to the at least one sensing element.

Sensor film for endoscopic instruments

The present disclosure provides a surgical shunt assembly tool that provides a more efficacious grip on the catheter tubes and prevent the tip of the catheter from buckling while the catheter is pushed onto the tip of the valve during installation of shunts during CSF shunt surgery. The tool includes standard handles such as used in a shodded mosquito tool having a clamping jaw integrated into the distal end section of the handle. The distal jaw includes two forcep jaw sections each having a proximal end integrally formed with a distal end of a distal end arm section of one of the two handle arms, and a distal end section extending away from the distal end arm section. The distal end sections of the forcep jaw sections are cylindrically shaped such that when the forcep jaw is closed by bringing the two forcep jaw sections together, a cylinder is formed having a diameter substantially equal to a diameter of a catheter tube to be attached to a shunt valve tip. The proximal ends of the forcep jaw sections are oval shaped and have a size such that when the forcep jaw is closed bringing the two forcep jaw sections together, an oval shaped opening is formed having a size smaller than the diameter of the catheter tube such that the catheter tube is squeezed closed to provide a firm grip of the tool of the catheter tube.

Surgical shunt assembly tool

A method for sensing at least one property with an instrument, wherein the instrument comprises an elongate shaft body; the method comprising the steps of: securing a sensor film conformally to the elongate shaft body, the sensor film comprising: at least one substrate core having a first surface and a second surface; at least one sensing element; a first conductive layer residing on the first surface, the first conductive layer having first solder mask coated thereon, and wherein the first conductive layer is grounded; a second conductive layer residing on the second surface, the second conductive layer having a second solder mask coated thereon, and coupled to the at least one sensing element; causing the at least one sensing element to measure at least one property and output a sensed signal and to convey the sensed signal via the second conductive layer to an electronics module.

A flexible elongate shaft assembly which includes an elongate flexible tube having at least one joint built into the elongate flexible tube, and the at least one joint comprised of at least one notch. Each notch includes a contact-aided compliant notch topology built into the elongate flexible shaft configured to cause each notch to mechanically interfere with itself and self-reinforce during bending of each notch resulting in an increase in stiffness of each notch to prevent buckling and plastic deformation of the elongate flexible shaft assembly, and assume a predetermined and designed bending shape of the elongate flexible shaft assembly. The flexible elongate shaft assembly is incorporated into a flexible articulate surgical tool that provides the needed stiffness in order to be able to manipulate tissue and bear loads in anatomically confined spaces. The surgical tool includes a clinician operated handle, the flexible elongated shaft assembly extending from the handle to a surgical tool with the flexible elongate tube having one or more joint sections located near the surgical tool. A flexible cable connects the handle to the surgical tool. The joint sections are configured so that when the clinician activates the surgical tool, a mechanical interference is generated in each of the notches and this mechanical interference not only increases stiffness throughout the articulation of the notch's range-of-motion but it also serves the dual purpose of controlling the bent 'shape' of the flexible portion of the notch.

Flexible articulate surgical tool

A surgical tool for compact articulating during surgical procedures includes a pitch cable, at least one yaw cable, a first link, a second link, at least one end-effector link, and at least one tensioning mechanism. The first link has a pitch joint end with a pitch joint pin and at least one yaw cable guide channel. The second link has a yaw joint end with a yaw joint pin. The second link is rotatably connected to the pitch joint pin. The at least one end-effector link is rotatably connected to said yaw joint pin. The yaw cables are coupled to the end-effector links such that the yaw cables can actuate the end-effector links about the yaw joint pin. The yaw cable guide channel is configured such that the yaw cables travel through a smooth trajectory to the end-effector links. The tensioning mechanism is configured to maintain a constant length.

An endoscopic instrument for use with a trocar, said endoscopic instrument comprising an elongate shaft body having a proximal end and a distal end; an end effector assembly at said distal end operable by manipulation of actuator mechanism at said proximal end; a substrate core having a first surface and a second surface; at least one sensing element on said first surface, said at least one sensing element located adjacent to said distal end; an electronics module for receiving sensed signals from said at least one sensing element, said electronics module located adjacent to said proximal end; a first conductive layer residing on said first surface, said first conductive layer having first solder mask coated thereon; a second conductive layer residing on said second surface, second conductive layer having a second solder mask coated thereon, and wherein said second conductive layer coupled to said at least one sensing element relays said sensed signals from said at least one sensing element to said electronics module and said a first conductive layer is grounded.

Simulators for practicing trans-oral surgery and methods of use thereof, are described. The simulator may include a simulated soft palate musculature adjacent to the simulated hard palate, and a simulated mucosal layer covering at least a portion of the simulated hard palate and at least a portion of the simulated soft palate musculature, wherein the simulated mucosal layer is configured to conform to and follow the contours of surface features of the covered portions of the simulated hard palate and simulated soft palate musculature.

A modular reconfigurable surgical robot for use in association with a surgical tool is disclosed. The surgical robot includes a linear module for linear movement; a turret module for rotational movement, and elbow roll module for rotational movement, and a wrist tilt module for rotational movement. The turret module has a turret rotational axis. The elbow roll module for rotational has an elbow roll rotational axis at an angle to the turret rotational axis. The wrist tilt module has a wrist tilt rotational axis at an angle to the turret rotational axis and the elbow roll rotational axis. The linear module, turret module, elbow roll module and wrist tilt module are operably connectable together to form the surgical robot and one of the modules is operably connectable to the surgical tool. The surgical robot may include an arch device unit attachable to one of the other modules.
