The breast biopsy tissue collecting and cleaning warehouse comprises 12 collecting cells and an outer warehouse. The outer warehouse is provided with 12 sub-grades, and the 12 collecting cells are respectively arranged in the 12 sub-grades. One end of the collecting cell is provided with an entrance for the biopsy tissue to enter the inside of the collecting cell. A long hole is formed in one side of the collecting cell for the biopsy tissue to be taken out from the inside of the collecting cell. The outer warehouse is provided with a plurality of cleaning ports for spraying cleaning liquid into the inside of the collecting cell to clean the biopsy tissue. The single tissue cut by rotation can be directly transported into the collecting cell in the collecting warehouse. The flushing function of the collecting warehouse can be used to flush the tissue clean. The risk that the single tissue is excessively contacted and adhered due to being concentrated together to damage the integrity of the tissue is avoided. The tissue does not need to be flushed again, the use steps of the medical staff are reduced, and the efficiency is greatly improved.

A motor mounting support in a closed breast rotary cutting sampling handle relates to the technical field of medical instruments and comprises a support body and an end cover, the detachable end cover is mounted at one end of the support body, three mounting cavities distributed in an inverted delta-shaped structure are formed in the support body, motor components are mounted in the mounting cavities, and output shafts of the motor components penetrate through the end cover; the support body and the end cover are installed in a matched mode, so that the assembly process is simplified, and the assembly efficiency and the equipment stability are improved; the through grooves are formed in the mounting cavity of the support body, so that heat dissipation of the motor assembly is facilitated, and the rigidity of the support body is improved.

It would be advantageous with the close quarters in breast procedure rooms to create a Gamma Probe system incorporating multi modalities, sensitivities, and multiple ranges for utilization in breast intervention procedures for the diagnosis and verification for breast cancer. Systems for specimen radiography assist radiologists and surgeons in the detection and classification of abnormal lesions in medical images gleaned from breast biopsies / lumpectomies and a Gamma Probe system with a sensor to detect radioactive, metallic / magnet, or RFID waves to help locate a lump or abnormality which were placed by an Interventional Radiologist. Radio guided surgery (RGS) uses gamma probes to localize radioactive targets. The three common RGS radioisotopes: technetium-99m (99mTc), indium-111 (111In), and iodine-125 (125I). The aspects of the disclosed embodiments pertain to a gamma probe that is able to simultaneously detect 2-3 isotopes automatically without actuating a physical switch.

This invention discloses a breast biopsy positioning device, comprising a bed board, a lifting mechanism, a housing, a positioning rod, a clamping device, and a drive mechanism. The housing is detachably mounted on the lifting mechanism, which drives the housing to move up and down perpendicularly to the bed board. The housing is hemispherical and annular, with its bottom opening facing the bed board. The housing includes multiple polygonal interlocking blocks, which are transparent. These interlocking blocks are detachably and sealed together to form the hemispherical housing. Each interlocking block has radially protruding holes penetrating its inner and outer surfaces, and a positioning rod is slidably inserted into each hole. Each interlocking block contains a clamping device. The drive mechanism is connected to all the clamping devices and drives all the clamping devices to simultaneously clamp and fix their corresponding positioning rods. This breast biopsy positioning device can perform puncture and positioning of the breast while reducing pressure on the breast and improving breast comfort.

A pneumatic stepper motor includes a housing, said housing accommodating at least part of: a rack or geared axle comprising a plurality of gear elements; and two pistons, each comprising at least two teeth, said pistons being arranged to cooperate with said rack or geared axle. The racks may either be straight or curved. The pistons are preferably double-acting pistons. A device includes at least one, and preferably a plurality of, such pneumatic stepper motor(s). The device may in particular be an MRI-compatible robotic system, more in particular for example an MRI-guided breast biopsy device.

A method and eyewear apparatus for reducing visual triggers during vascular access or interventional procedures or other medical procedures or treatments. One method uses a vision-restricting eyewear apparatus comprising a lens with an opaque lower region and an affixed compressible foam pad that together obstruct the subject's lower field of vision while preserving partial forward or upward visibility. When worn, the apparatus forms at least a substantially continuous, gapless visual barrier that limits exposure to procedural stimuli for effective blocking. The method and apparatus aim to reduce physiological and psychological distress, including vasovagal responses. In one non-limiting embodiment, a vision-restricting apparatus and associated method are provided for reducing visual triggers during vascular access, breast biopsy, or other interventional procedures. The apparatus includes a lens or eyeshield having an opaque lower region configured to obstruct the user's inferior visual field while preserving forward or upward visibility through a transparent upper region. Affixed along the lower edge of the lens is a compressible, skin-safe foam or other interface that deforms by folding or bending against itself, forming a continuous, gapless visual barrier that conforms to a variety of facial anatomies. In some embodiments, the apparatus comprises a single continuous lens or eyeshield body or discrete lenses for each eye, and may further include a support frame or adhesive interface for facial adhesive of the apparatus to a patient. The method comprises applying the apparatus immediately prior to a needle-based or image-guided procedure to position the visual obstruction in place, thereby reducing physiological or psychological distress—such as vasovagal responses—by blocking distress-inducing stimuli within the lower visual field. The apparatus is suitable for single-use disposable application.

The utility model relates to medical equipment technical field discloses a breast biopsy specimen sampling storage box, including box body and the sealing cover hinged on box body, the handle that can be stored in the box body is slidably installed on the sealing cover, the locking mechanism that can be automatically locked is arranged between box body and sealing cover, and the inside of box body is equipped with a plurality of storage compartments, and the four corner places of every storage compartment all have the rounded corner integrally formed, the utility model discloses through the several storage compartments of the rounded corner of box body inside, realize the classification of different specimens to avoid confusion, eliminate the right angle dead angle and facilitate cleaning, the handle of slidable storage is through connecting rod and box body square groove, sealing cover sliding groove and placement groove cooperation, in the time of handling, pull out and use, when not using, completely retract, avoid the label and be convenient for stacking storage of shielding, and the locking mechanism of torsional spring and guide surface realizes the automatic locking when sealing cover closure, need not manual operation locking structure.
