Abstract: A device for the fluid-conveying connection of at least one application probe. The device comprising at least two coaxially extending application line elements, with a supply tubing set, said tubing set comprising at least two parallel-extending supply line elements, in a grip element of a surgical instrument such as a cryosurgical instrument, such that, in a connected state, each supply line element is in fluid communication with at least one associated application line element. A fluid-diverting element is provided and arranged, or can be arranged, in the grip element in fluid communication with an application line connecting region for the connection of the application line elements and with a supply line connecting region for the connection of the supply line elements. At least two transfer line elements designed as an integral part of the fluid-diverting element are in fluid communication with the application line connecting region via the application line connecting region.

Abstract: A handle for a surgical instrument, in particular a cryosurgical instrument, comprising a grip element and at least one sheathing tube that is inserted into the grip element and connected with said grip element in a fluid-tight manner in a connecting region. At least one support element is coaxially configured and arranged in the cavity of the sheathing tube such that the sheathing tube is clamped in place between the grip element and the support element in the connecting region.

Abstract: A device for the sealing connection of a pressure hose with a grip element of a surgical instrument. The device comprising at least one sealing element that, in an assembled state, is interposed between the grip element and the pressure hose in a connecting region to create a seal. A support element is provided and arranged in the connecting region in the interior of the pressure hose such that the sealing element is clamped, or can be clamped, between the support element and the pressure hose on one side and the grip element on the other side. In addition, a handle for a surgical device, in particular a cryogenic surgical instrument, comprising a grip element for holding the surgical instrument and comprising at least one pressure hose that is connected, or can be connected, with the grip element via the device for the sealing connection.

Abstract: A slotted grate (2) is provided for being positioned in and covering the opening of the channel body (1) of a drainage channel. Anchor means are provided for detachably securing grate (2) to channel body (1) and include a bolt (4) rotatably mounted on grate (2) and having an end (14) extending into channel body (1). A locking strap (5) is carried transversely by bolt (4) for rotation within channel body (1) into and out of proximity to the walls (7, 7') of channel body (1). Locking blocks (8, 8') are carried by walls (7, 7') and secure locking strap (5) within locking blocks (8, 8') upon rotation of locking strap (5) in one direction, and permit detachment of locking strap (5) upon rotation of locking block (5) in the other direction. Therefore, grate (2) can be easily and quickly secured to or detached from channel body (1), as desired.

Abstract: The drainage channel comprises a channel body (1), cast frame (2) and cast grid (3). The support surface of the side walls (11) of the channel body (1) are of stepped construction, with a raised external supporting rib (13). The frame (2) is rectangular, with a lowered support rail (28) as support for the side ribs (30) of the grid (3). On the outside the frame (2) has detachably fastened brake lugs (23), which in the installed state prevent displacement of the frame (2). Locking bar holders (44) of roughly H-shaped cross-section are disposed in the side walls (11) some distance below the support surface. These locking bar holders form a closure between the interior of the channel body and the exterior. On the inside a side wall (79) forms an obtuse angle with the wall (75), so that the locking bar (45) can easily be turned into the inner recess (78).

Abstract: A slotted grate (3) is disclosed which is formed of a sheet metal strip with slot (15) therein. Reinforcement of the grate (3) is achieved by inserting a sheet metal arch support (30) between two adjacent slots (15). The arch support (30) is formed of a piece of sheet metal bent into a U-shape with shoulders (35, 36) of its end sections (31) being spaced further apart than the shoulders (37, 38) of its midsection (32). A process is disclosed wherein the slotted grate (3) is constructed by first placing arch supports (30) between the desired slots (15) and then double bending the edge sections of the sheet material forming the grate (3) to form two U-shaped side channels with the shoulders (35, 36) of arch support (30) locked securely therein.
