A surgical handpiece nosecone having an end overmold portion and/or an internal overmold portion. The end overmold portion is located at an end of the nosecone and compressed between the surgical handpiece housing and nosecone. The internal overmold portion is positioned radially about the nosecone on the inner surface to provide a fluid tight seal that prevents ingress of irrigation fluid into the housing.

The invention relates to the grouting field, in particular to a grouting device for high-coagulability grouting materials. The grouting device comprises a grouting pipe, a connector and a self-sealing pipe head, wherein one end of the connector is connected with a grouting pump through the grouting pipe, the other end of the connector is connected with the self-sealing pipe head through the grouting pipe, and the grouting pipe is connected with the connector and the self-sealing pipe head in a fixed and sealed mode. The grouting device is easy to install, features reliable connection between the grouting pipe and the connector and the self-sealing pipe head, and can be reused. Because the inner diameter of the connector is consistent with the inner diameter of the grouting pipe, and a slurry outlet on an end cap of the self-sealing pipe head is a circular slurry outlet, pressure loss in the grouting process is effectively reduced, and the grouting effect is good.

A coupling part for a hose coupling, a hose coupling provided therewith and method for coupling a hose or hose part. The coupling part includes an annular element; a number of hook-like coupling elements arranged at or on the annular element and configured to engage on a corresponding coupling element of a corresponding coupling part for the purpose of forming a coupling; and a wall surface provided on the inward directed side of the hook-like coupling element and provided at an angle of chamfer to the main throughflow direction of the coupling part.

A female pipe coupling member includes a coupling body and a sleeve 138 disposed around a cylindrical peripheral wall portion of the coupling body. The sleeve has a locking element receiving hole extending therethrough from an inner peripheral surface to an outer peripheral surface. When the sleeve is in a locking element releasing position where the locking element receiving hole radially aligns with a locking element, the locking element is received in the locking element receiving hole to assume an unlocking position. The locking element receiving hole is configured to block the locking element from passing therethrough radially outward and thus holds the locking element in the unlocking position from outside.

An assembly, connector and method is disclosed for making a fluid connection between a vessel wall and a fluid tube. The assembly includes a male connector having a cylindrical body and an internal fluid passage through the male connector between a head portion located at an upper end of the male connector and a base portion on a lower end of the male connector. An aperture is formed on the vessel wall and at least first and second recesses are formed along an edge of the aperture. The base portion has at least first and second locking members located in a spaced relation to the other on opposite sides of the base portion and a sealing flange extends circumferentially about the base portion. The base portion is arranged to be installed in the aperture with each locking member accepted within a respective recess. Rotation of the male connector causes the locking members to rotate within the aperture and seal the sealing flange against the wall. A female connector connected to the fluid tube is installed on the male connector head portion.

A quick connector assembly connects to and establishes fluid communication with a male end port. The quick connector assembly includes a female component and an internal clip carried by the female component. The quick connector assembly receives the male end port in a single predetermined rotational orientation for retaining the male end port and the quick connector assembly non-rotatable receives the male end port.

Connector assemblies, connector bodies, fluid systems including connector assemblies, and procedures for making fluid connections are disclosed.
