According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

Systems and methods for minimally invasive tele-surgery are described. For example, the disclosure describes methods for independently controlling motions of the robotic manipulator, cannula, and surgical instrument in various surgical contexts.

A medical puncture device system includes a puncture device, a sensor, and an indicator system. The puncture device is configured to create a puncture through patient tissue and into an internal patient cavity to enable a medical tool to be inserted through the puncture into the cavity. The sensor is configured to generate a signal indicative of motion of the puncture device through the tissue into the cavity. The indicator system is operable by a controller to produce human-perceptible feedback in response to the signal generated by the sensor.

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.

The invention provides systems and methods for performing a minimally invasive vasectomy procedure by supplying targeted RF energy to vas deferens via a pair of probes positioned within the vas deferens under ultrasound image guidance.

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.

The invention relates to a surgical apparatus, in particular a navigation probe for localizing and treating lesions in a brain, comprising a telescopically expandable body member having an anterior end, a posterior end, and comprising a top part and a bottom part, the bottom part having at least one groove extending for a particular length in a longitudinal direction of the bottom part between said anterior end and said posterior end, the top part being placed on said bottom part and having at least one engaging element that extends into said at least one groove so as to mount the top part on the bottom part moveable in said longitudinal direction, wherein the body member has a substantially circular or polygonal cross-section in the assembled state of the bottom part and the upper part.

A medical device may include an introducer sheath, having a distal and a proximal end and a lumen extending from the distal end to the proximal end. The introducer sheath may also include a tab formed at the distal end and extending distal to the lumen, and a frangible portion extending between the distal end and the proximal end.
