A needle groove plate (5), a puncture support (100) and a biopsy device are disclosed. The puncture support (100) includes a main body (1), a rod (4), and a needle groove plate (5), wherein the main body (1) can be connected to an ultrasonic probe (200) and is provided with a channel (13), and the length of the channel (13) is less than the length of the rod (4); the rod (4) can from a first end thereof go into the channel (13) and slide back and forth in the channel (13) along a first direction, the first direction being parallel to an extending direction of the rod (4); and the needle groove plate (5) is fixed to a second end of the rod (4), and is provided with at least one needle penetration hole (513) parallel to the first direction. The technical solution provided by the present invention not only optimizes the structure of the puncture support (100) and reduces its volume, but also reduces manufacturing costs; flexible and telescopic operations can be made between the rod (4) and the main body (1), so that the position of the needle groove plate (5) is adjustable, thereby preventing the needle groove plate (5) from pressing the perineum of a patient and reducing discomfort in a puncture process; further, a puncture needle can be separated from the puncture support (100) and the ultrasonic probe (200) during surgery, thereby facilitating flexible operations by a doctor.

A cannula insertion system for cannulating a blood vessel includes a cannula system having a cannula that defines a cannula lumen and has a distal and proximal end. The system includes a cannula insertion device for coupling with the system that includes a dilator having a dilator body and a dilator lumen; a needle having a needle body and a needle lumen, the needle being translatable within the dilator lumen along a first direction; a movable dilator actuator configured to cause the dilator to move along the first direction; a movable needle actuator configured to cause movement of the needle along the first direction; and a housing defining housing recess. The housing recess is configured to receive the cannula system, the dilator, and the needle. The needle and the dilator are configured to be moved within the cannula lumen along the first direction.

The present invention relates to a medical needle device, and more specifically, to a medical needle device capable of drilling a fine passage in an affected part of a patient, or collecting a portion of tissue in the body of the patient. Through the present invention, a needle and a handle of the medical needle device may be separated, and thus the device may be conveniently used while not obstructing the view of the affected part when using same.

Further, through the present invention, the handle and the needle are unshakably fastened, and thus may be stably used.

Provided are systems and methods for tactile sensing of a target tissue region of a patient in need thereof.

A transseptal insertion device is provided including device housing, a pusher slidably disposed in the device housing and a guide element extending from the pusher. The device housing is configured to be inserted into the right atrium of a patient's heart and the guide element can then be advanced from the device housing and against the cardiac septum to facilitate stable puncturing of the cardiac septum by a needle carried by a catheter inserted through the device housing, to provide access to the left atrium. The guide element can be formed as a webbing or ring. The pusher and/or guide element can optionally be inflatable.

A system and method for reducing the risk of contamination of interior regions of a needle guide which is disposed on an endocavity transducer, which system includes an elastic membrane forming a pocket which covers a needle exit hole in the needle guide. The pocket is disposed on a sheath which is both; disposed around the endocavity transducer and between the endocavity transducer and the needle guide.

A surgical instrument retainer can include a proximal component and a distal component. The proximal component can include a head, a first body, and a proximal plurality of projections. The distal component can define a second instrument bore and a body bore and can include a distal plurality of projections. The can head engageable with the end effector coupler to position the instrument retainer within the end effector coupler.

Disclosed is a brain implant placement apparatus, which includes a base member contoured to rest against a cranium of a patient. The brain implant apparatus including a pivot arm hingedly coupled to the base member and configured to rotate from a first configuration to a second configuration. The brain implant placement apparatus including an implant attachment member coupled to the pivot arm via a rotating attachment mechanism and further comprising a receiving portion configured to removably couple with a brain implant and rotate the brain implant. In the first configuration, the pivot arm is positioned such that the receiving portion of the implant attachment member is facing upward. In the second configuration, the pivot arm is positioned such that the receiving portion of the implant attachment member is facing substantially downwards.

Transradial access devices, systems, and methods. An exemplary device of the present disclosure for providing access to a vessel or other luminal organ and to prevent overperforation of the same including a needle having a needle tip and at least one current element positioned thereon or embedded therein at or near the needle tip, a sheath positioned around at least part of the needle, and a protractor in communication with the needle, whereby engagement of the protractor causes the needle tip to protract from the sheath through the aperture, and whereby release of the protractor causes the needle tip to retract through the aperture into the sheath. Activation of the at least one current element can facilitate vasodilation of the vessel or other luminal organ.

An anatomical sensing system-guided prostate procedure device that includes a housing having a proximal end and a distal end. The housing may be divided into a distal housing section, a mid housing section, and a proximal housing section, wherein the distal housing section is configured for insertion into the anus and retention in the rectum of a subject. The device further includes an instrument convergence point disposed between the proximal end and the distal end, the convergence point configured to allow an instrument pass though the instrument convergence point at a variable angle; and an instrument angle orienting system at the proximal end of the housing, the angle orienting system directing an orientation of the variable angle about the convergence point. Methods of the using an anatomical sensing system-guided prostate procedure device and system including the same.
