20090082735 | Surgical sealing element, surgical seal, and surgical sealing system - In order to improve a surgical sealing element, in particular, for a trocar and/or for sealing shafts of elongated surgical instruments during insertion into a human or animal body, wherein the sealing element defines a longitudinal axis, is provided with an opening, which is variable in diameter and is oriented transversely or essentially transversely to the longitudinal axis and through which an instrument can be inserted, and comprises a flexible wall which is closed annularly, wherein the wall has a first and a second edge each closed upon itself and wherein the first edge limits the opening, such that all instruments currently available can be reliably sealed irrespective of the diameter of their instrument shaft it is suggested that the wall be foldable in a wave-like manner and in a sealing position be folded in a wave-like manner without kinks with fold lines extending in the direction towards the first edge in such a manner that the first edge defines a wave line which is located entirely on a cylindrical surface. | 03-26-2009 |
20090118755 | Surgical Obturator - To enable puncture of a body wall with a greater degree of sensitivity with a surgical obturator for puncturing the body wall having a knife, the cutting edge of which extends outwards from a tip of the obturator in the direction of various sides and backwards in relation to the tip, and which is orientated throughout its entire length parallel to the puncturing direction, so that the cutting edge points in the puncturing direction, it is proposed that the cutting edge be of helical line-shaped configuration. | 05-07-2009 |
20090138034 | Surgical obturator - In a surgical obturator for piercing a body wall, comprising a tubular housing that at one end forms an introduction tip with a continuously decreasing diameter, and comprising a blade projecting from the introduction tip for making an incision in the body wall, in order to reduce the risk of injury during piercing of the body wall it is proposed that the introduction tip comprises a central protective cap, which is displaceable in longitudinal direction relative to the introduction tip between an advanced inoperative position and a retracted working position, that the blade in the housing is displaceable in longitudinal direction between an advanced cutting position and a retracted protected position, that disposed in the housing is a retraction device that displaces the blade from the cutting position into the protected position, and that the retraction device may be activated by a displacement of the protective cap from the working position into the inoperative position. | 05-28-2009 |
20100010446 | Surgical sealing element holder for holding a surgical sealing element and surgical sealing system - In order to improve a surgical sealing element holder for holding a surgical sealing element of a surgical sealing system comprising a trocar with a trocar sleeve, the sealing element having an insertion opening which can be widened, such that a sealing element of the sealing system can be replaced in a simple and reliable manner and it is ensured that sealing in relation to a channel of the trocar sleeve is perfect at all times it is suggested that a holder sealing element be provided for sealing the sealing element holder with respect to an inner wall surface of the trocar sleeve. | 01-14-2010 |
20100016799 | Surgical protection device for a surgical sealing element and surgical sealing system - In order to improve a surgical protection device for a surgical sealing element of a surgical sealing system comprising a trocar, the sealing element having an insertion opening which can be widened, the protection device comprising a base member which can be arranged on the trocar or on a part thereof, is closed in a ring shape and has an opening and several protection elements which are arranged in circumferential direction and point parallel or towards a longitudinal axis of the protection device, the protection elements having free ends pointing essentially in a distal direction, such that protection of the sealing element can be as complete as possible irrespective of the degree of expansion thereof, it is suggested that at least some of the protection elements have retaining elements on an outer side at their free ends or in the area of their free ends for engagement with the sealing element. | 01-21-2010 |
20110040255 | Surgical sealing element, surgical seal and surgical sealing system - A surgical sealing element, for example, for a trocar and/or for sealing shafts of elongated surgical instruments during insertion into a human or animal body, is provided. The surgical sealing element comprises a flexible wall closed annularly, the wall comprising a first edge and a second edge, and an opening for a shaft of a surgical instrument, the opening being variable in diameter and limited by the first edge. In a sealing position, the wall is folded with fold lines extending in a direction towards the first edge in such a manner that the first edge defines a wave line. | 02-17-2011 |
20110106144 | Surgical instrument - In order to provide a surgical instrument which is particularly simple to manipulate and enables force to be transmitted particularly directly to at least two tool elements wherein the surgical instrument comprises said at least two tool elements which are movable relative to one another and are arranged at a distal end of a guide device of a surgical instrument, and also comprises a force transmission device for transferring an actuating force from a proximal end of the force transmission device to a distal end of the force transmission device for the purposes of moving at least one of the at least two tool elements relative to the guide device, it is proposed that the surgical instrument should comprise a coupling device for selectively coupling the force transmission device directly or indirectly to at least one of the at least two tool elements. | 05-05-2011 |
20120238957 | SURGICAL SEALING ELEMENT HOLDER FOR HOLDING A SURGICAL SEALING ELEMENT AND SURGICAL SEALING SYSTEM - In order to improve a surgical sealing element holder for holding a surgical sealing element of a surgical sealing system comprising a trocar with a trocar sleeve, the sealing element having an insertion opening which can be widened, such that a sealing element of the sealing system can be replaced in a simple and reliable manner and it is ensured that sealing in relation to a channel of the trocar sleeve is perfect at all times it is suggested that a holder sealing element be provided for sealing the sealing element holder with respect to an inner wall surface of the trocar sleeve. In addition, an improved surgical sealing system is provided. | 09-20-2012 |
20130116510 | SURGICAL ACCESS DEVICE AND SURGICAL ACCESS SYSTEM - In a first aspect of the invention, a surgical access device for inserting surgical instruments into the body of a patient comprises a sleeve section defining a longitudinal axis and also a working channel. A ratio between a length and an internal diameter of the sleeve section lies in a range of approximately 4:1 to approximately 14.
