A forceps instrument comprises, for the support of at least one pivotally supported branch, a bearing insert which is inserted into a base in order to support at least one pivotable branch. The bearing insert may be inserted transversely with respect to the pivot axis into a corresponding compartment of the base and fixed there in the compartment, due to detent action. The bearing insert comprises two bearing elements, including cylindrical journals, which are arranged on bearing parts of the bearing insert, without being in contact with each other, the bearing parts having the form of plates, that are oriented parallel to each other. The two journals come into engagement with corresponding openings of the branch, in which case the distance remaining between the end sides of the journals can be used for the arrangement of miscellaneous elements, including a cutting knife.

The present application is directed to a medical instrument with a hollow shaft, a handle arranged at the proximal end of the shaft and a tool tip with a tool arranged at the distal end of the shaft, wherein the tool can be actuated via an actuating element mounted in the shaft, the element being in an operative connection with the handle and the tool tip being pivotable relative to the shaft via a joint mechanism, the joint mechanism having pivoting members, wherein inside the hollow shaft at least one guide device is arranged for the steering wires connecting the pivoting members to the drive. In order that the steering wires can be installed easily and without crossing, the at least one guide device is arranged coaxially on the actuating element, and the at least one a guide device is mounted on the actuating element so that it cannot rotate.

Provided are surgical instruments, and more particularly, surgical instruments that may be manually operated to perform laparoscopic operations or various surgical operations.

A forceps includes a drive assembly and an end effector assembly having first and second jaw members movable between a spaced-apart position, a first approximated position, and a second approximated position. The drive assembly includes a drive housing and a drive bar. The proximal end of the drive bar is coupled to the drive housing, while the distal end of the drive bar is coupled to at least one of the jaw members. The drive housing and the drive bar are selectively movable in conjunction with one another between a first position and a second position to move the jaw members between the spaced-apart position and the first approximated position. The drive assembly is selectively activatable to move the drive bar independent of the drive housing from the second position to a third position to move the jaw members from the first approximated position to the second approximated position.

A surgical instrument that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.

This application provides an endoscopic device having at least one shaft with at least one portion deflectable, and having at least one deflection mechanism, which is configured to deflect the deflectable portion and includes at least one first connection member and at least one second connection member. When the connection members are arranged in a straight position relative to each other, a straight-position spacing exists defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member and, when the connection members are arranged in a deflection position relative to each other, a deflection-position spacing exists which is defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member, and the deflection-position spacing in the deflection position is greater than the straight-position spacing in the straight position.

An exemplary embodiment relates to a bearing assembly (40) for a swash plate (14) in a steering gear component (33), wherein the swash plate (14) is arranged such that it can rotate about an axis of rotation (10) in a radial bearing which is located in a receiving opening (330) of the steering gear component (33). The radial bearing is a sliding bearing (35) and the bearing assembly (40) has at least one axial securing device (36) which is arranged axially adjacent to a first side of the swash plate (14) and engages with the steering gear component (33). Furthermore, a surgical instrument (1) is disclosed that has this bearing assembly (40) of a swash plate (14) in a steering gear component (33).

The present invention relates to an endoscopic treatment instrument, and more particularly, to an endoscopic treatment instrument including a detachable end-effector and a contamination prevention cover. The endoscopic treatment instrument includes an end-effector for performing treatment in the endoscopic surgery or an endoscope treatment, a connection section being detachably coupled to an end of the end-effector, and a contamination prevention cover being coupled to the connection section or the end-effector and surrounding a portion of an outer peripheral surface of the connection section so as to prevent contamination of the connection section. According to an embodiment of the present invention, since only the end-effector is separable for replacement and the cover is formed to protect a control unit, it is possible to prevent cross infection between patients caused by the contamination of the end-effector and the control unit.

In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.
