Provided is a biopsy instrument having an outer needle-locking member, which is capable of checking whether an inner needle is placed in target tissue and shooting an outer needle after the tissue is sufficiently introduced into the inner needle, thereby accurately collecting the target tissue that is to be.

A universal single-handed device for self-collection of a biological sample is described herein. The single-handed device may comprise a sheath comprising a distal end for insertion into a portion of a user's body, a shaft at least partially within the sheath, having a collection head for collecting the biological sample positioned at the distal end thereof, and an actuator coupled to the shaft to transition the distal end between an open configuration and a closed configuration. The collection head is covered by the distal end in the closed configuration and is exposed when the distal end is in the open configuration.

Devices and methods used to obtain core tissue samples are disclosed. The devices may be configured to drill into cortical bone and saw a hole into a bone lesion and/or bone marrow while obtaining the core tissue sample. The devices can include a motor and a clutch configured to rotate a trocar having a tip configured for drilling and an outer coax cannula having a trephine tip configured for sawing. The core tissue sample may be received within an inner cannula as an intermediate cannula cuts a hole in the bone lesion and/or bone marrow. The devices can include a spacer.

An impact biopsy device is disclosed. The impact biopsy device may be configured to displace various cutting elements, such as an outer tubular member and cutting element and a cannula to sever a tissue sample from a patient. The impact biopsy device may comprise an actuation system configured to transfer displacement or force to the cutting elements by the impact of an element on another element.

A biopsy apparatus includes a piercing module having a probe drive slider coupled to a probe carrier body of a biopsy probe assembly, and has a primed position and a fired position. A nut housing has a home position and an extended position. A drive spindle is drivably coupled to a motor driveshaft, and is coupled to the nut housing. A firing spring is interposed between a motor housing and the probe drive slider. A release arm is pivotably coupled to a piercing module frame. When the probe drive slider is in the primed position and the release arm is in a latch position, the release arm is positioned to engage the probe drive slider to hold the probe drive slider in the primed position. A release slider releases the release arm from the latch position when the nut housing is moved from the home position to the extended position.

Limited physical access to target organs of patients inside an MRI scanner is a major obstruction to real-time MRI-guided interventions. Traditional teleoperation technologies are incompatible with the MRI environment and although several solutions have been explored, a versatile system that provides high-fidelity haptic feedback and access deep inside the bore remains a challenge. A passive and nearly frictionless MRI-compatible hydraulic teleoperator is provided designed for in-bore biopsies. A needle driver translates a needle in insertion and retraction directions via a clutch mechanism. A needle holder grips the needle via a retraction lock when the clutch mechanism of the needle driver releases the needle to hold a position of the needle during reposition of the needle driver.

A biopsy device includes an elongated handle body having a proximal end portion and a distal end portion, a needle disposed within the handle body, first and second transducers, and a display. The needle is configured to move between a retracted position and a deployed position. The first and second ultrasound transducers are disposed within the distal end portion of the handle body. The first and second ultrasound transducers are angled relative to one another and define a space therebetween configured for passage of the needle.

A full core biopsy device includes a needle assembly having stylet, spoon, and at least one coring cannula. A window is located in at least one of the spoon and coring cannula. A excising finger is configured to prolapse through the window into a lumen of the inner spoon or cannula to sever a tissue sample upon translation or axial advancement of the excising finger.

A breast biopsy lateral arm system includes a removable gun mount which attaches to a carriage that traverses along an X-axis defined by a lateral arm in order to position a biopsy needle relative to a patient. The carriage rides along the lateral arm on self-adjusting rollers which are loaded against the lateral arm by spring members. A cam-actuated carriage slide lock can be used to secure the carriage in a desired position relative to the lateral arm. A cam-actuated removable gun mount lock allows the gun mount to be quickly changed and offset orthogonally with respect to the X-axis. An X-axis stop can be used to establish a position to which the carriage can be returned with accuracy.

A biopsy device includes a disposable elongated probe component having a coaxial arrangement of an elongated tubular section and an elongated tissue cutting member, and having a coaxial arrangement of a first driven gear, a second driven gear, and a third driven gear. The first driven gear is configured to rotate the elongated tubular section. The second driven gear is configured to rotate to longitudinally move the elongated tissue cutting member. The third driven gear is configured to rotate or oscillate the elongated tissue cutting member. A driver component has a coaxial arrangement of a first drive gear, a second drive gear, and a third drive gear. The first drive gear is drivably engaged with the first driven gear. The second drive gear is drivably engaged with the second driven gear. The third drive gear is drivably engaged with the third driven gear.
