Single-port laparoscopy minimally invasive surgery robot system

The invention discloses a single-port laparoscopy minimally invasive surgery robot system, which comprises a function end and a control end, wherein the function end comprises a function mechanical arm, an image shooting illumination module and a sleeve pipe module, the control end comprises an image shooting illumination module control module, a function mechanical arm control module and a fixing module, the image shooting illumination module control module can realize the extension, retraction and bending of the image shooting illumination module, and the function mechanical arm control module can realize the extension, retraction and bending of the function mechanical arm and the opening and the closing of a tail end executer so that the image shooting illumination module and the function mechanical arm can enter the operation position of the abdominal cavity in the posture of retracting into the sleeve pipe module, and in addition, after the function mechanical arm reaches the operation position through a single cut, and in addition, the image shooting illumination module and the function mechanical arm can move to the specific space position to enter the work posture after reaching the operation position. The maximum diameter of the function end of the single-port laparoscopy minimally invasive surgery robot system is only 12mm, so the single-port laparoscopy minimally invasive surgery robot system has the advantages that the size is small, the use is convenient, safety is realized, and the like.

Expandable ablation burr

An atherectomy burr has an operating diameter that is larger than the diameter of a catheter in which the burr is routed. The burr may include an expandable polymeric balloon having a partially abrasive exterior surface. The maximum expansion of the burr is controlled by an expansion mechanism. Various mechanisms are disclosed for controlling the maximum diameter of the burr thus preventing the burr from over expanding. In addition, the present invention includes systems that are pulled proximally to remove portions of a lesion located in a patient's vasculature. The system includes an ablation burr that has abrasive disposed on the proximal end. The burr may create a seal when expanded to block the ablated particulate so that an aspiration system can remove the particulate from the vasculature. Alternatively, the burr system may include a self expanding seal that is deployed out of the aspiration sheath.

Transdermal delivery system for the administration of rotigotine

An improved Transdermal Delivery System (TDS) comprising a backing layer inert to the components of the matrix, a self-adhesive matrix containing rotigotine and a protective foil or sheet to be removed prior to use, characterized in that the self-adhesive matrix consists of a solid or semi-solid semi-permeable polymer (1) wherein rotigotine in its free base form has been incorporated, (2) which is saturated with rotigotine and contains said rotigotine as a multitude of microreservoirs within the matrix, (3) which is highly permeable for the free base of rotigotine, (4) which is impermeable for the protonated form of rotigotine, (5) wherein the maximum diameter of the microreservoirs is less than the thickness of the matrix. is provided. Said TDS provides for enhanced flux of rotigotine across the TDS / skin interface.

Cervical canal dilator

A cervical canal dilating assembly and method of use are shown. The dilator assembly includes a plastic shaft, a first inflatable member, and a second inflatable member. The shaft can range from being rigid to being highly flexible. The second inflatable member is fabricated of a non-elastic material and is configured to have a maximum inflatable diameter. The second inflatable member is configured to have a predetermined maximum inflatable diameter ranging from 4 to 20 mm. The dilating assembly can also be at least partially covered by a sheath. A control system includes means for measuring pressure configured for at least monitoring the pressure of the second inflatable member. A wire can be used in selected configurations to stiffen and shape the shaft. In operation, the initial penetration of the dilating assembly into the uterus uses a wire for increased stiffness. The dilating assembly is then forwarded through the remainder of the cervical canal. The first inflatable member is expanded in the uterus after being uncovered by the sheath. The second inflatable member is positioned in the cervical canal and gradually inflated to a predetermined maximum diameter.

Spatial characterization of a structure located within an object by identifying 2d representations of the structure within section planes

InactiveUS20100099979A1Clear visualizationPrecise quantitative comparisonImage enhancementImage analysisSection planeSonification
It is described a virtual pullback as a visualization and quantification tool that allows an interventional cardiologist to easily assess stent expansion. The virtual pullback visualizes the stent and / or the vessel lumen similar to an Intravascular Ultrasound (IVUS) pullback. The virtual pullback is performed in volumetric data along a reference line. The volumetric data can be a reconstruction of rotational 2D X-ray attenuation data. Planes perpendicular to the reference line are visualized as the position along the reference line changes. This view is for interventional cardiologists a very familiar view as they resemble IVUS data and may show a section plane through a vessel lumen or a stent. In these perpendicular section planes automatic measurements, such as minimum and maximum diameter, and cross sectional area of the stent can be calculated and displayed. Combining these 2D measurements allows also volumetric measurements to be calculated and displayed.
