Molded article and hollow tube
A coating film is provided in a cable, a medical hollow tube, a molded article and a hollow tube. The coating film is formed from a rubber composition including a rubber component and fine particles. A static friction coefficient on a surface of the coating film is 0.5 or less. When the coating film is subjected to a testing such that a long fiber non-woven fabric including cotton linters including an alcohol for disinfection with a length of 50 mm along a wiping direction is brought contiguous to the surface of the coating film at a shearing stress of 210.sup.3 MPa to 410.sup.3 MPa, followed by wiping off the surface of the coating film at a speed of 80 times/min to 120 times/min and 20,000 repetitions thereof for a wiping direction length of 150 mm, a difference (an absolute value of a difference) between the static friction coefficients of the coating film before and after the testing is not greater than 0.1.
Operation switching mechanism and endoscope
An operation switching mechanism includes a wire, a reciprocating movement member, a first biasing member, a second biasing member, switching members configured to switch states in which the first biasing member and the second biasing member perform biasing, and an operation member configured to operate the switching members according to operation from an outside and move the reciprocating movement member to a first movement position or a second movement position.
MEDICAL DEVICE WITH DISTAL TORQUE CONTROL
A catheter with a distal end that rotates through the conversion of linear motion to rotational motion, thus the distal end may be rotated without longitudinally advancing or retracting the distal end. The catheter includes a tube with a single helix or a dual chirality helix cut into the tube, a distal end segment, means for linear displacement of the helix, and means for coupling the junction point of the helix to the distal segment.
Steerable catheter handle
A steerable-catheter handle includes an outer housing with a multilumen catheter body extending generally distally therefrom. An internal track, including at least one track-defining lateral edge element, is disposed between distal and proximal terminal ends of the outer housing, which also houses a manifold engaged with the catheter body, a working-channel port member in fluid and mechanical communication with at least a first catheter lumen, a vacuum channel port member in fluid communication with at least one catheter lumen via one or both of the working channel port member and the manifold, and a generally proximal catheter port open to the internal track, where a distal endmost portion of the catheter mechanically communicates with one or more control surfaces so that the distal endmost portion of the catheter is deflectable along at least two intersecting axes, and where a portion of the catheter body extends removably through the internal track.
Endoscopic immersion probe end optics for laser spectroscopy
In one aspect of the present disclosure, improved end optics are disclosed that maximize the numerical aperture focused at a sample point while minimizing unwanted artifacts such as vignetting. The configurations also maintain centering of the excitation/collection beam on the objective if the probe tilts or bends. The disclosed configurations are particularly suited to probes wherein the excitation and/or collection paths between the probe and the laser/analyzer are coupled through multimode fibers, such as in Raman and other forms of laser spectroscopy. The disclosure includes the insertion of one or more additional lenses between the probe head and the focusing objective at the probe tip.
Endoscope having support body with segmented annular space
An endoscope including an elongated shaft. The elongated shaft including: an inner shaft tube in which an optical system is received; an outer shaft assembly including an outer shaft tube and a tubular support body proximally abutting the outer shaft tube; at least one bundle of optical fibers disposed between the inner shaft tube and the outer shaft tube; and an electrical connector arranged between the inner shaft tube and the support body. Where the support body includes at least a first web and a second web each extending radially between an inner surface of the support body and an outer surface of the inner shaft tube, the first web and the second web also extending in a longitudinal direction of the shaft such that an annular space between the inner shaft tube and the support body is divided into at least two segments.
Electronic device for an endoscope, and endoscope
An electronic device including: a multilayer printed circuit board; and a molded retaining body; wherein the printed circuit board is formed of structured layers of conducting and non-conducting materials adhered together, the conducting materials form conductor tracks and contact areas, the printed circuit board being stiffened in a rigid region by stiffening material, the rigid region having electronic components and encapsulated in an epoxy; the printed circuit board having a flexible region that is more flexible than the rigid region, the flexible region having contact areas; the retaining body having an arc-shape formed on a radial inner side of the retaining body for arrangement on an inner tube of an endoscope; the retaining body having, on a radial outer side, a receiving contour for receiving and shaping the printed circuit board; and the retaining body having a retainer for holding the printed circuit board in a bent state.
Video laryngoscope and video laryngoscope insertion section
A video laryngoscope and elongate laryngoscope insertion section for a video laryngoscope, comprising a viewing port through which an imaging device within the insertion section can obtain images of a larynx, the insertion section extending between a distal end for insertion into a subject and an opposite proximal end, and having an inferior surface and an opposed superior surface, wherein the insertion section comprises a proximal region where the insertion section extends through a subject's teeth in use, a distal region extending to the distal end and an intermediate region therebetween, wherein the inferior surface of the insertion section comprises or consists of a curved region which extends from the proximal region through the intermediate region to the distal region, wherein the curved region of the inferior surface is continuously longitudinally curved along the length of the longitudinally curved region and wherein the longitudinal curvature of the curved region of the inferior surface varies in the intermediate region. Markings on an elongate laryngoscope insertion can be used to monitor depth of insertion and to indicate a path by which an endotracheal tube should be inserted.
JOINT DRIVING ACTUATOR AND MEDICAL SYSTEM
[Object] To more simply configure a joint driving actuator having a function of a brake. [Solution] A joint driving actuator according to the present disclosure includes: an ultrasonic motor configured to generate driving force for driving a joint; a torque sensor configured to detect external force applied to the joint; and an encoder configured to detect a rotational angle of the ultrasonic motor. This configuration makes it possible to more simply configure a joint driving actuator having a function of a brake.
ENDOSCOPE TIP ACCESSORY DEVICE WITH DIMENSION VARIABILITY COMPENSATION
Embodiments of the disclosure include an endoscope accessory assembly for use on an endoscope, during procedures. The endoscope accessory assembly may comprise an accessory device comprising a first base, a plurality of flexible struts, and webbing connecting each of the flexible struts. The accessory device is configured to receive a distal end of an endoscope. The endoscope accessory assembly may further comprise a dimension-compensating component comprising a second base, a plurality of flexible arms extending radially out from the second base, and at least one chamber at a distal end of the flexible arms.
