摘要： The invention relates to a cryosurgical instrument, in particular a biopsy instrument for transbronchial biopsy, having an elongate instrument base body with a distal and proximal end, in relation to the operational position, a cooled section which is close to the distal end and which removes tissue, said section being designed in such a manner that surrounding biological material adheres thereto, by means of cryoadhesion, when said instrument is in use in the cooled state, and a security section which is provided at a distance from the tissue removal section and which comprises means for preventing or reducing the adhesion of biological material.

摘要： The invention relates to cryosurgical instrument for obtaining a tissue sample using a probe, wherein the probe comprises a probe head for freezing tissues, a probe shaft for advancing the probe head to the tissue, a feeding device for feeding a fluid into an expansion chamber and a conducting device. The conducting device is connected to the expansion chamber for delivering the expanded fluid out of the expansion chamber. The expansion of the fluid in the expansion chamber chills the probe head such that the tissue freezes to the probe head. Such surgical instruments can also be used according to the invention in thin hollow organs, such as gall bladder or pancreatic ducts, in order to obtain tissue samples. In said area of application, however, certain requirements are placed on the dimensions of the probe that could not be met by conventional probes. The present invention solves said problem in that the delivery device comprises at least one opening at the distal region of the probe, said opening conducting the fluid into an external region outside of the probe. According to the invention, a part of the expanding gas is thereby discharged directly into the hollow organ.

摘要： The invention relates to a water jet surgical instrument (10), comprising a feed line (22) for feeding a cutting fluid, and an ejection nozzle (11) for forming and ejecting a fluid jet at a predetermined expansion angle and/or at a predetermined discharge energy. A jet-forming device (12) is disposed relative to the ejection nozzle such that the fluid jet is or can be adjusted by the jet-forming device with respect to the expansion angle and/or the discharge energy thereof.

摘要： The application relates to a cryosurgical instrument for separating a tissue sample from a biological tissue that is to be treated. The cryosurgical instrument (10) comprises a probe (40), for bringing a probe head (42) to the biological tissue to be treated, and a gas delivery device for delivering coolant gas from a gas source of a cryosurgical appliance to the probe head, wherein the latter is designed in such a way that, by means of the delivered gas, a limited area of tissue can be cooled, in order to recover a tissue sample, and can be separated from the surrounding tissue in a state frozen onto the probe head. The instrument is designed to allow a tissue sample to be collected reliably and in a manner that is gentle on the tissue and that provides a high degree of safety for the patient. For this purpose, the instrument comprises a support tube (60) in which the probe is guided and which is movable relative to the probe in such a way that the surrounding tissue can be supported by means of the support tube during the separation of the tissue sample. An accelerating device (110) is also provided, which makes available a predefined force for the separation procedure.
