The present disclosure is related to surgical devices, more particular it refers to a surgical clamp that attaches to a patient's bone to assist in surgical procedures. The surgical clamp is configured in such a manner that the clamping elements show a movement in a plane different from the plane of the actuator intended for opening and closing said clamping elements. As a result, the surgical clamp provides a broader working space to the surgeon when carrying out surgical work on the spine.

A method (of manufacturing fins for a semiconductor device) includes: forming semiconductor fins including ones thereof having a first cap with a first etch sensitivity (first capped fins) and second ones thereof having a second cap with a second etch sensitivity (second capped fins), the first and second etch sensitivities being different; and eliminating selected ones of the first capped fins and selected ones of the second capped fins.

The invention relates to a recalibration device (1) used during the acquisition of images of an anatomical area of a patient during robot-assisted surgery, including a body (3) made of radxoliacent material, which comprises fiducial markers (9) made of radiopaque material, said body (3) having a bearing surface (7) intended to be manually placed on a surface of said anatomical area of the patient. According to the invention, said fiducial markers (9) are arranged in a specific geometrical pattern enabling a certain detection of the positioning and orientation of the recalibration device (1) in a three-dimensional digital model built from the images derived from the acquisition of the anatomical area.

A device for providing a fiducial marker(s) within or near a target tissue (e.g. nodule, tumor or other) within a patient. The present teachings provide a system that includes a handle device, a catheter having a proximal end and a distal end, wherein the proximal end of the catheter is coupled to the handle device, and a monolithic material slidably received within the catheter. The monolithic material includes a stylet comprising a proximal end and a distal end, a fiducial marker having a proximal end and a distal end, and a failure section that mechanically couples the distal end of the stylet to the proximal end of the fiducial marker. The fiducial marker is configured to transition from having a first shape state inside the catheter to having a second shape state upon expulsion from the distal end of the catheter. The failure section is configured to mechanically fail in response to experiencing a heat value greater than a predefined threshold.

A method includes receiving during a first time interval associated with a path of motion of a dynamic body, image data associated with a plurality of images of the dynamic body. The plurality of images include an indication of a position of a first marker coupled to a garment at a first location, and a position of a second marker coupled to the garment at a second location. The garment is coupled to the dynamic body. During a second time interval, an image from the plurality of images is automatically identified that includes a position of the first marker that is substantially the same as a position of a first localization element relative to the dynamic body and a position of the second marker that is substantially the same as a position of the second localization element relative to the dynamic body.

A biopsy marker having a spring-loaded anchor. The biopsy marker includes an insertion orientation and an anchored orientation. In the insertion orientation, the biopsy marker is manipulated under force to reduce the lateral span/cross-sectional area of the marker. In the anchored orientation, the biopsy marker is released and free to actively spring into a configuration in which the lateral span/cross-sectional area is greater than the lateral span/cross-sectional area of the biopsy marker when in the insertion orientation. In an embodiment, the spring-loaded anchor is configured to spring about a predefined rotational axis. An embodiment of the biopsy marker may be comprised of a single wire construction.

A biopsy marker having a spring-loaded anchor. The biopsy marker includes an insertion orientation and an anchored orientation. The lateral span/cross-sectional area of the marker is configured to change when transitioning between the insertion orientation and the anchored orientation. In an embodiment, the spring-loaded anchor is configured to spring about a predefined rotational axis. An embodiment of the biopsy marker may be comprised of a single wire construction.

Tissue localization devices and methods of localizing tissue using tissue localization devices are disclosed. The tissue localization device can comprise a handle comprising a delivery control, a delivery needle extending out from the handle, and a localization element within the delivery needle. The localization element can be deployed out of the delivery needle or retracted back into the delivery needle when the delivery control is translated in a first direction or a second direction, respectively. The localization element can be coupled to a flexible tracking wire.

A gold marker recovery device for radiotherapy positioning and its using method comprises a positioning gold marker and a recovery clamp, the positioning gold marker comprises a gold marker body and an elastic fixed structure, the elastic fixed structure comprises a fixed segment, an extending segment and a spiral segment connected in sequence; the fixed segment is embedded in the gold marker body so that the fixed segment is closely connected with the gold marker body, A magnetic ball is arranged at one end of the gold marker body away from the extending segment; the recovery clamp comprises an operating handle, the rear end of the operating handle is connected with an outer sheath tube in a hollow structure, and the outer sheath tube is connected with a zipper for driving the clamp to open and close.

Device 1 for fixation to the skull 2 of a patient that can serve as a fiducial marker in scan guided surgical operations using a surgical instrument. The device 1 comprises a material translucent for the applied electromagnetic waves of the scan and a fiducial marker and where the device 1 comprises means to fixate the device in a well-defined manner to the surgical instrument.
