20100292724Minimally Invasive Surgical Clamps, Assemblies and Methods - A minimally invasive surgical assembly broadly includes an outer tube which has an outer diameter of 3.0 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow tube. The coaxial surgical instrument includes end effectors at the end of the shaft. The end effectors include spring arms and wire frame clamp elements defining fenestrations. The spring arms are biased to an open position such that when the end effectors of the surgical instrument extend out of the outer tube they open, and they are closed by relative movement of the outer tube over them. The wire frame clamp elements are biased to an open position such that when they extend out of the outer tube they open and they are closed by relative movement of the outer tube over them.11-18-2010
20100318112OBTURATOR TIPS - A trocar assembly for use in minimally invasive surgical procedures includes a cannula subassembly and an obturator subassembly. The obturator assembly includes an obturator shaft member defining a longitudinal axis and an obturator tip configured to be removable from the obturator shaft member or, alternatively, constructed with the obturator member as a single unit. Various designs of the obturator tip are contemplated.12-16-2010
20130184733DEVICE FOR THE REPEATED PIERCING OF AN ORGANIC TISSUE, AN APPLICATION MODULE AND A METHOD THEREOF - A device for repeated piercing of an organic tissue and method thereof are disclosed. The device may comprise an arrangement of application tools each of which is connected to an operating mechanism and has a distal tool end which is formed for at least one application tool with a penetration device, whereby by way of the operating mechanism the tools can be displaced relative to each other between an initial position and a penetration position. During the relative movement, the effect direction of an application force provided by at least one application tool is counter to the effect direction of the application force provided by the other application tool. A mechanical actuation device, which is connected to the operating mechanism, is suitable for repeatedly effecting the relative displacement of the at least one application tool between the initial position and the penetration with an operating frequency.07-18-2013
20130184732TISSUE HARVESTING APPARATUS - A tissue harvesting apparatus is provided which can reliably prevent a worker from being stabbed with a needle tip of a needle tube at the time of disposal. When disposing a used tissue harvesting apparatus used for harvesting of a living body tissue, a sheath member with a puncture pipe body (a puncture needle) inserted and arranged in the inside thereof is wound in the form of a loop around an operating rod and locked in a locking groove. Then, a needle tip of the puncture pipe body protruding from a leading end of the sheath member is housed and fixedly supported in a needle housing hole formed in an end face of a second flange portion on the base end side of the operating rod.07-18-2013
20120289985MEDICAL INSTRUMENT - A medical instrument includes a medical needle configured to puncture a tissue, and a tissue-supporting member configured to be inserted into the lumen of the medical needle and supports the tissue. The medical needle includes an insertion portion that has a longitudinal axis, a lumen that is formed along the direction of the longitudinal axis of the insertion portion, an opening portion that is formed at the distal end of the insertion portion while being connected to the lumen, and a puncturing portion that is formed in the periphery of the opening portion and has a pair of projections sharply protruding in a direction extending toward the distal end from the proximal end of the insertion portion.11-15-2012
20130197559MINIMALLY INVASIVE SURGICAL TECHNIQUES - Apparatus and methods are described including a trocar (08-01-2013
20130197558SKIN NICKING DEVICE, METHOD AND ASSEMBLY - A device, method and assembly for nicking skin is disclosed. The device includes a lumen is that is slideable over an introducer needle, and a blade at the end of the device. The device may include a shield for restricting advancement of the device during a skin nicking procedure. The device may also include a retractable blade or guard as a safety and nicking customization feature. A recess can also be shaped in the device for slideably attaching the device to an introducer needle hub.08-01-2013
20120035641Surgical Obturator - An obturator has an elongated shaft with a first shaft portion and a second shaft portion within an obturator housing. The distal end of the first shaft portion creates a first shield and the distal end of the second shaft portion creates a second shield. A blade having a piercing tip and cutting edges is interposed between the first shield and the second shield. In use, once the piercing tip passes the body wall, the first shield moves to cover the piercing tip and protect internal organs from accidental injury while the cutting edges continue to cut the body wall. Once the second shield passes through the body wall, the second shield moves to cover the cutting edges.02-09-2012
20130204286LAPAROSCOPIC INSTRUMENT AND TROCAR SYSTEMS AND RELATED SURGICAL METHOD - Laparoscopic instruments and trocars are provided for performing laparoscopic procedures entirely through the umbilicus. A generally C-shaped trocar provides increased work space between the hands of the surgeon as well as S-shaped laparoscopic instruments placed through the trocar when laparoscopic instrument-trocar units are placed through the umbilicus. In order to facilitate retraction of intra-abdominal structures during a laparoscopic procedure, an angulated needle and thread with either one-or two sharp ends is provided. Alternatively, an inflatable unit having at least one generally C-shaped trocar incorporated within the unit's walls can be placed through the umbilicus following a single incision. Generally S-shaped laparoscopic instruments may be placed through the generally C-shaped trocars to facilitate access to intra-abdominal structures.08-08-2013
