A biopsy arrangement for taking a biopsy in a human or animal tissue, said biopsy arrangement comprising: —a needle arrangement (3) comprising an elongated inner needle part (5) and an elongated outer needle part (7), which outer needle part (7) is a hollow member in which the inner needle part (5) fits coaxially, wherein the two needle parts can be provided in at least two different positions in relation to each other; —an activator (11) which is arranged in the biopsy arrangement (1) such that it can be moved within the biopsy arrangement, said activator (11) comprising: —a first activating part (13) which is configured to control a needle locking device (21) provided in the biopsy arrangement (1) to lock or not lock the inner needle part (5) and the outer needle part (7) to each other; and —a second activating part (15) which is configured to control a needle translation device (31) provided in the biopsy arrangement (1) to change a position of the inner (5) and outer needle parts (7) in relation to each other, said needle translation device (31) being connected to at least one of the inner or outer needle parts (5, 7), whereby a movement of the activator (11) within the biopsy arrangement (1) can affect a position of both the first and the second activating parts (13, 15) whereby both the needle locking device (21) and the needle translation device (31) can be controlled.

Medical instrument for taking a tissue sample in the body, the instrument includes an inner tube and an outer tube mounted axially slideable over the inner tube. The inner tube possesses a distal end with a cutting spiral and a proximal end to turn the spiral in the tissue to be sampled. The outer tube possesses a distal end with a cutting edge to cut loose the tissue in the spiral by sliding the outer tube over the spiral. Both tubes over at least an overlapping axial length of 30 cm are executed flexibly bendable because over said length the tubes are provided with one or more grooves which extend through the wall of the tubes and which open upon torsion in one direction.

Provided is an adhesive tape for collecting skin indigenous microorganisms, the adhesive tape being capable of providing improved collection yields of skin indigenous microorganisms on a skin surface. This adhesive tape is for collecting skin indigenous microorganisms, is used to collect skin indigenous microorganism on a skin surface, and comprises a base material and an adhesive layer provided on at least a portion of a surface of the base material, wherein the adhesive layer contains an adhesive, and the adhesive contains a rubber adhesive. The adhesive tape has an adhesive strength of 10.0 N or more when a 12 mm-wide test piece thereof is pressure-bonded to a Bakelite plate by one reciprocation of a 2 kg roller and then measured for adhesive strength at a pulling speed of 300 mm/min and a pulling angle of 90° according to JIS Z 0237: 2009, and the adhesive tape has a peel strength of 0.25 N or more when a 12 mm-wide test piece thereof is measured using a silicone-treated fine paper sheet as a release sheet and measured for peel strength at a pulling speed of 300 mm/min and a pulling angle of 180° according to JIS Z 0237: 2009.

A handle for a medical device includes a proximal segment defining a proximal lumen extending therethrough and sized and shaped to receive an endoscopic medical device therein. A medial segment is received within a distal portion of the proximal segment and has an outer diameter smaller than an inner diameter thereof. A medial lumen extends through the proximal segment and is open to the proximal lumen. A distal segment is received within a distal portion of the medial segment and defines a distal lumen extending therethrough open to the medial lumen. The distal segment has an outer diameter smaller than an inner diameter of the medial segment. The medial segment includes a first movement limiting mechanism limiting movement of an endoscopic medical device inserted therethrough along an axis of the distal lumen and a second movement limiting mechanism limiting advancement of an endoscope attached to the distal body portion.

A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described, as well as alternative systems for tissue preservation and transport. The cutting device includes an outer cannula in which a reciprocating inner cannula is disposed. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A temperature control sleeve may be disposed around the tissue collector to control the temperature of the tissue samples. A preservation system may be supplied that is configured to deliver fluids to tissue samples in the tissue collector. A fluid supply sleeve may be disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

An integrated ablation needle (100), comprising a cannula (10) and an electrode needle (20) that is movably and penetratingly installed within the cannula (10); the electrode needle (20) comprises a needle tip (21) located at the far end and a needle rod (23) connected to the near end of the needle tip (21); at least a portion that is near to the needle tip (21) of the needle rod (23) is provided with a sampling groove (231); and the far end of the cannula (10) is provided with a cutting edge (11). The cannula (10) moves along the axial direction relative to the needle rod (23) so as to expose or cover the sampling groove; when the sampling groove (231) is exposed, a tissue portion around the needle rod (23) enters the sampling groove (231); and when the sampling groove (231) is covered, the cutting edge (11) cuts off tissue inside and outside of the sampling groove (231), such that the tissue within the sampling groove (231) is acquired as a biopsy sample. Further provided is an ablation system (1000) comprising an integrated ablation needle (100). The integrated ablation needle (100) and the ablation system (1000) integrate ablation and biopsy functions on the same ablation needle (100), without needing to independently execute a biopsy step, thus avoiding repeated puncturing, reducing damage to the human body, and reducing operation time.

A biopsy system for harvesting larger volumes of tissue as compared to standard core biopsy needles. The system has a needle with a lumen, an aperture disposed at the distal end of the needle and connected to the lumen, and a cutting mechanism adapted to cut tissue. When the needle is rotated after it is inserted into a target tissue, the cutting mechanism cuts from the tissue and directs the cut tissue portions into the lumen. Multi-bioimpedance measurements are used to guide a needle and direct the application of electricity for cauterizing tissue.
