  • Bendable portion of an insertion tube of an endoscope and method of producing it
    Patent number: 7766821
    Abstract: A bendable portion, which is arranged at the distal end of an insertion tube of an endoscope, comprises a plurality of tube segments, each of said tube segments having connecting means that cooperate with the connecting means of the adjacent tube segment, as well as control wires that can control the bending of the bendable portion. The respective connecting means of a tube segment are provided such that they axially protrude from the faces of the tube segment and are located within the mantle of the tube segment and such that they do not exceed the thickness of the mantle. The connecting means, which are provided on the respective faces of adjacent tube segments and which are located opposite each other, complement each other in the manner of a hinge-type connection.

  • SYRINGE, IN PARTICULAR FOR VETERINARY-MEDICINE APPLICATIONS
    Publication number: 20100081999
    Abstract: A syringe for veterinary-medicine applications has a main body with a syringe cylinder whose discharge-side end is connected to a cannula and in which a piston connected to a piston rod is situated so it is displaceable. The syringe includes a protective module including protective cap and a securing element. The protective cap is mounted so it is displaceable on the main body, which receives the cannula in its first terminal position so that the front end thereof does not protrude from the protective cap. The securing element can be moved from a first securing position into a second securing position and then into a third securing position. The securing element releases a locking of the piston rod relative to displacements, so that the piston can be moved in the syringe cylinder in the direction toward the discharge-side end using the piston rod.

  • Method for effecting local increases in temperature inside materials, particularly body tissue
    Patent number: 7645235
    Abstract: Local tissue areas should be thermally destroyed when using ultrasound thermotherapy. Traditionally, mono-frequency continuous wave ultrasound signals are used to this end. These lead to a non-optimal distribution of heat or to a non-optimal localization of the heating inside the tissue. In practice, the following dosage problem arises: the prevention of unwanted tissue damage in the tissue located in front of the target area while simultaneously having a sufficiently high damaging effect in the target area. The aim of the invention is to optimize the distribution of heat or to increase the localization of the heating. To these ends, modified transmitted signals (e.g. multi-frequency signals) are used that are adapted to a specific utilization of the non-linear ultrasound propagation and attenuation properties inside the tissue.

  • ENDOSCOPE SYSTEM
    Publication number: 20080188716
    Abstract: An endoscope system includes a radiation source which emits a modulated radiation and is applied in a manner such that an object to be examined by an endoscope may be illuminated with the radiation. A sensor is provided for detecting the radiation reflected by the object, at least one picture point.

  • Veterinary syringe
    Patent number: 7341574
    Abstract: A veterinary syringe comprises a base body for receiving a syringe barrel with a guiding element for a plunger rod that is guided therein so as to be movable in a longitudinal direction. At one end of the plunger rod, a plunger is attached that extends into the syringe barrel. The syringe further comprises a handle and an operating lever. The operating lever is connected to a guiding element that engages with a toothed rack associated with the plunger rod, and with a locking device for the plunger rod that engages with the toothed rack. The locking device acts as a locking slider disposed inside the guiding element and has an opening through which the plunger rod is guided and extends into the toothed rack from below, locking the toothed rack so as to prevent it from withdrawing.
