A system and method for prostate cancer treatment under local anesthesia includes creating a superficial skin and subcutaneous block in a perineal area of a patient by administering a first anesthetizing agent; creating a deep nerve block under ultrasound guidance by administering a second anesthetizing agent, the second anesthetizing agent infiltrating cavernosal nerve bundle tissue and periprostatic space; and ablating prostate tissue. The office-based method, statistical models and computer generated treatment plans identify and ablate prostate tissue containing cancer through or via the perineum while preserving prostate function, and critical anatomical structures. Multiple technologies are integrated and processed to deliver a safe treatment procedure, under local anesthesia by integrating the information of magnetic resonance imaging and planning the ablative treatment using algorithms that ensure maximal precision in both killing cancerous tissue and preserving healthy tissue along with its corresponding function.

Techniques and technologies for guiding medical instruments during medical procedures using real-time imaging technologies are disclosed. A representative apparatus includes a medical instrument, an imaging system, a stage assembly, and a control system. The medical instrument includes an elongated portion configured to be inserted into a body portion and having an optical fiber that includes a tip portion that is extendable beyond a distal end of the elongated portion. The imaging system provides a sampling energy that is emitted from the tip portion. The stage assembly actuates the tip portion to perform scanning of one or more tissues with the sampling energy. The imaging system receives a reflected energy, providing a plurality of one-dimensional arrays of intensity values of the reflected energy. The control system analyzes the plurality of one-dimensional arrays of intensity values to determine a shape and a location of the target tissue, and displays information for guiding the medical instrument into engagement with the target tissue.

An adaptor for mounting on an imaging transducer includes a hollow housing configured to receive a portion of the imaging transducer. The housing comprises a coupling member for enabling releasable securement of a needle guide device to the housing, wherein the needle guide device includes a body member and a lockable mounting member. The coupling member comprises a projection portion that projects outwardly from the housing, wherein the projection portion includes first and second undercut recesses on opposing sides of the projection portion, wherein the projection portion is configured for receipt in a recess in the body member, the recess in the body member including at least one stop portion. The first undercut recess is configured to receive the stop portion, and the second undercut recess is configured to receive an engagement portion of the lockable mounting member when the lockable mounting member is moved from an unlocked position to a locked position to releasably secure the lockable mounting member to said coupling member, thereby releasably mounting the needle guide device on the imaging transducer.

The present disclosure presents a trajectory array guide system for defining a trajectory to a target location in the brain of a subject and for guiding an elongated tool along the trajectory. The trajectory array guide system can comprise: a base, an array guide, an imaging unit, and an elongated handle configured for connection with a stereotaxic navigation system. The present disclosure presents a method of using a trajectory array guide system for defining a trajectory to a target location in the brain of a subject and for guiding an elongated tool along the trajectory.

The invention relates to a holder device for holding a medical instrument, the device comprising:

a base that is to be carried by an apparatus comprising a medical imaging probe associated with the medical instrument; and

a carrier structure for carrying the medical instrument and movably mounted on the base so as to be capable of moving on the base between a first position and a second position.

The invention also relates to an installation including both such a device and a needle-guide.

The present disclosure relates to an auxiliary device and auxiliary method for epidural anesthesia needle placement, the auxiliary device comprising: a needle placement unit (1), a motion guide unit (2) for driving the needle placement unit into movement, and a control unit (3) for supporting and controlling the motion guide unit (2), the needle placement unit (1) being electrically connected to the control unit (3); the needle placement unit (1) comprises: a first support (11) connected to the motion guide unit (2), a second support (12) slidably connected with the first support (11), a needle placement assembly (13) slidably connected with the second support (12), and a first drive (14) arranged on the first support (11) for driving the second support (12) into motion. The scheme of the present disclosure may perform a real-time multidimensional monitoring to the puncture process, achieving autonomous, precise, safe needle placement and puncture operations.

A surgical method for operating a trocar defining an access port for a surgical instrument, using a holding arm and a number of drives. The method includes: inserting the trocar through an abdominal wall of the patient body; operating at least one drive to move the surgical instrument in the patient body; operating at least one drives to actuate an effector; and moving the holding arm to generate a pivoting movement of the trocar and surgical instrument about a pivot point defined by the abdominal wall of the patient body. The trocar is freely pivotable relative to the holding device, and the pivoting movement is caused by contact between the trocar and the abdominal wall of the patient body or an elastic membrane located on the abdominal wall of the patient body.

A biopsy and therapy device comprising: a needling unit for holding and inserting a biopsy needle; an imaging module comprising an ultrasound probe and an actuator for moving the probe in a reciprocal action; a first arcuate slide; a second arcuate slide in sliding engagement with the first arcuate slide and a linkage to which the first arcuate slide is mounted; said linkage arranged to move the first and second arcuate slides within a vertical plane; said needling unit mounted to said arcuate slide wherein the first and second arcuate slides are mounted perpendicular to each other so as to rotate the needling unit about respective first and second principal axes.

Sensors are disclosed that detect whether a cannula is properly inserted to its full depth in a subject's skin. The sensors may be used with a blood glucose monitor, or with a continuous insulin infusion pump, infusion set, or other system involving intermittent or continuous testing and/or drug delivery.

An improved guide for a medical needle is disclosed herein. An aligning element for aligning a needle guide, which is equipped for longitudinally guiding a medical needle, includes a connecting element for arranging the aligning element on the needle guide, and a light-guiding element for a predetermined diffusion of light. The light-guiding element only generates a predetermined light pattern relative to the diffusion of light in a pose predetermined by the geometry of the apparatus. Such an aligning element may be used in a treatment arrangement for longitudinally guiding a needle and in a method for aligning a needle guide.
