Translation of "Tissue specimen" in German

When collecting a first tissue specimen, the operator depresses the clamping key 90 .

If a tumor is discovered after taking a breast photograph of a patient, a tissue specimen must be taken from the tumor.

If the tumor on the photograph is disposed precisely in such a ring, the physician can locate the corresponding hole on the plate and conduct, by means of a biopsy needle, through the hole, a puncture of the breast of the patient who is still in the X-ray examination apparatus, in order, in this manner, to take the tissue specimen.

If a tumor is ascertained in the x-ray image, it is necessary to remove a tissue specimen from the tumor tissue.

This invention is therefore based on the objective of creating a cannula for biopsy needles which, while avoiding the mentioned disadvantages of the shown state of the art, can be developed with the smallest diameter but, at the same time, permits the removal of a sufficient, cleanly cut tissue specimen without the danger of a destruction of cells.

This invention relates to a cannula for biopsies having a cylinder jacket wall surrounding an axial hollow space for receiving a tissue specimen and having at least one blade with two cutting sides ending, at an acute angle, in a cutting edge.

Before the physician punctures the breast with the biopsy needle at coordinate point 32 in order to remove a tissue specimen, the collimator tube 11 can be removed in order that there will be sufficient room for the biopsy needle.

The needle is then pulled out of the tissue, and biopsy specimen 3 is exposed again by pulling the hollow needle back.

Further subject matter of the present invention relates to a kit for isolating biomolecules from a fixed biological specimen embedded in paraffin, in particular a tissue specimen which contains at least the following components:

At the point where a tissue or a specimen needs to be excited, a sufficiently intense excitation spectrum is of essential importance.

In this phase, the operator must decide whether to initiate the clamping of the clamping carriage, or to collect a further tissue specimen after a first specimen has been collected, for example.

After the biopsy needle has been removed from the tissue and a container has been prepared for receiving the tissue specimen and the tissue fluid, the programming key 89 is depressed again and the ejection diode 93 begins to blink.

If desired for the customer's service, the kit contains further materials for the dehydration of the tissue specimen such as 100% alcohol with molecular sieve and silica gel.

Severing the long-side cutting surfaces of the tissue specimen to be removed through the movement of the needle attains a superior filling capacity, even with hard and/or leathery tissue or tissue having inclusions.

The confocal images also enable a physician to reach a quick diagnosis without time-consuming and complex dyes applied to a tissue specimen.

During the test the tissue specimen is attached to the upper and lower platforms using a thin coating of superglue and immersed in a suitable physiological, temperature-conditioned solution.

Localization of IL--2-R containing cells is possible in cultured cell colonies or in tissue specimens.

The individual tissue specimens are arranged here in a matrix structure, for example, like a chessboard.

The biological tissue in the specimens conducts electricity in the familiar way.

Apart from medical documents, such results include X-rays, CT or MRI images or tissue specimens.

Human intervertebral disc tissue specimens were obtained from eight patients.

The cassettes available in several colours serve for safe embedding of tissue specimens.

Such methods can be used, for example, in medical technology for the automatic recognition of cancer cells in tissue specimens.

Thorough impregnation of all types of tissue specimens can be achieved with either open or closed automatic processor systems.

Furthermore, CT-guided biopsies of all organ regions for acquiring tissue and specimens, including CT-guided therapies, are offered.

Where available, archival tumour tissue specimens taken prior to chemoradiation therapy were retrospectively tested for PD-L1 expression on tumour cells (TC) using the VENTANA PD-L1 (SP263) IHC assay.

Pre-study tumour tissue specimens were systematically collected prior to randomisation in order to conduct pre-planned analyses of efficacy according to tumour PD-L1 expression.

A general staining procedure, such as haematoxylin and eosin (H&E), should be performed on all tissue specimens embedded in paraffin and microscopic examination should be carried out.

In this embodiment, the removal of tissue specimens, for example from a tumorous tissue, is possible with the aid of a biopsy needle.

When so required, these channels can be used for passing though cleaning fluid, for example, in order to clean an area which is to be examined, or CO2 (air) for opening out the cavity, or else various working instruments can be pushed through a working channel, for example forceps or scissors for removing tissue specimens, biopsy needles, heatable cutting wires, coagulation electrodes, which can likewise be manually operated at the rear end of the endoscope shaft via operating wires or Bowden cables inside the inner channel.
