The present disclosure discloses use of a copper-chromium alloy in a medical biopsy puncture needle. The copper-chromium alloy used as a material for a needle core and/or needle tube of the puncture needle. The copper-chromium alloy includes the following components by mass: 10≤Cr≤20, 0.04≤Zr≤0.1, and the balance of Cu. According to the present disclosure, a copper alloy with designed components is obtained by combining a diamagnetic material Cu with paramagnetic Cr and Zr, and compared with existing medical stainless steel and titanium alloy, the copper alloy has greatly reduced magnetic susceptibility, and specifically, the artifact area and volume are also significantly reduced. In addition, the blank of use of the copper alloy in medical biopsy paracentesis is filled.

A biopsy device includes an elongated housing having a manifold, an outer cannula partially and slidably disposed in the manifold, and an inner cannula partially and slidably disposed in a lumen of the outer cannula. The biopsy device further includes an outer cannula seal disposed between the manifold and the outer cannula, the outer cannula seal including an interference ring portion disposed adjacent an inner surface of the manifold, a beaded ring portion that contacts an outer surface of the outer cannula, and a flexible portion extending between the interference ring portion and the beaded ring portion.

A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit one or more signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the one or more signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply one or more instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element.

A target biopsy system employing an ultrasound probe (20), a target biopsy needle (30) and a ultrasound guide controller (44). In operation, the ultrasound probe (20) projects an ultrasound plane intersecting an anatomical region (e.g. a liver). The target biopsy needle (30) include two or more ultrasound receivers (31) for sensing the ultrasound plane as the target biopsy needle (30) is inserted into the anatomical region. In response to the ultrasound receiver(s) (31) sensing the ultrasound plane, the ultrasound guide controller (44) predicts a biopsy trajectory of the target biopsy needle (30) within the anatomical region relative to the ultrasound plane. The prediction indicates the biopsy trajectory is either within the ultrasound plane (i.e., an in-plane biopsy trajectory) or outside of the ultrasound plane (i.e., an out-of-plane biopsy trajectory).

The present application includes a method for introducing a hormone directly into an affected area within a tumor. The method includes penetrating the affected area of the tumor with a biopsy needle in order to obtain a biopsy specimen. The specimen is withdrawn along with the biopsy needle. A hormone implant is inserted into the void space left behind as the specimen was removed. The method may also include directly inserting the implant and a treating substance into the tumor without the removal of the biopsy specimen. The implant may have various shapes in order to maximize surface contact. The implant is also configured to have a time release function to regulate dosage delivery.

Shaped liver biopsy sheaths and methods for transfemoral transcaval liver access are disclosed. The present invention provides methods of obtaining a tissue sample from the liver of a patient, the methods comprising inserting a hollow sheath, such as a stiffened sheath with an angled tip, through a femoral vein into a portion of the inferior vena cava (IVC) adjacent to the liver, wherein the sheath's tip is in the intrahepatic IVC and wherein the sheath has a shape that brings the tip of the sheath adjacent to the wall of the IVC at an angle that is optimal to allow penetration of the wall of the IVC by a biopsy needle, and inserting a biopsy needle through the sheath and through the wall of the NC into the liver to obtain a tissue sample from the liver.

In a biopsy needle having a hollow tubular outer needle, an inner needle that is disposed in a hollow portion of the outer needle so as to be movable in the tube axis direction relative to the outer needle, and a recessed sample collection portion that is cut inward from a circumferential surface of the inner needle, an inner hole that extends in the longitudinal direction of the inner needle on each of the inner needle distal end side and the inner needle rear end side of the sample collection portion and are opened to the sample collection portion is provided in the inner needle, and a light guide member is disposed in the inner holes. At least a part of the light guide member is fixed by filler filled in the inner holes.

A biopsy needle includes: a tubular outer needle including a first needle tip at one end in a longitudinal direction of the outer needle; and an inner needle having a columnar shape and configured to be inserted into the outer needle and movable along the longitudinal direction. The inner needle includes: a second needle tip at a distal end of the inner needle; an inclined surface that is inclined toward the second needle tip; and concave portions provided on first and second side surfaces of the inner needle, the first side surface facing a first direction perpendicular to a cross section parallel to the longitudinal direction, the second side surface facing a second direction opposite to the first direction, a part of the inclined surface being included in an area obtained by projecting the concave portions in a direction parallel to a transverse direction of the inner needle.

A method of analysis using mass spectrometry and/or ion mobility spectrometry is disclosed comprising: (a) using a first device to generate smoke, aerosol or vapour from a target in vitro or ex vivo cell population; (b) mass analysing and/or ion mobility analysing said smoke, aerosol or vapour, or ions derived therefrom, in order to obtain spectrometric data; and (c) analysing said spectrometric data in order to identify and/or characterise said target cell population or one or more cells and/or compounds present in said target cell population.
