The invention relates to tubular shaft instruments, which are provided with a handle, a tubular shaft and a tool head. The tool head usually has two mouth parts, which can be displaced in relation to one another for gripping and fixing tissue. The disadvantages of the articulations used for this purpose are that they block access to the mouth parts from the inside of the tubular shaft to the outside, that they are not sufficiently stable and can only be operated with low leverage. The invention thus discloses a slotted guide system for forming the articulation, said system having a virtual fulcrum outside the tubular shaft instrument. The invention not only eradicates the aforementioned problems but also simplifies the seizure of tissue.

The invention provides a spout for a pouch, which can be reliably heat-sealed with a plastic pouch body to provide an excellent gas-shielding capability for preventing gas permeation through the spout itself, and can be simply manufactured at a low cost without requiring complicated processes and special materials. In a spout for a pouch, comprising a tubular mouth part having a cap fitting portion and a seal part connected to a lower end portion of the mouth part for sealing with the pouch, the invention is featured in that a horizontal cross-sectional shape of the seal part is different in a height direction between an upper end portion and a lower end portion thereof, and an outer peripheral length of the horizontal cross-sectional shape is substantially equal at any position between the upper end portion and the lower end portion of the seal part.

A protective face mask is provided. The protective face mask may have a removable mouth panel (or “apron”) which acts as a protective personal barrier for the user. The removable mouth panel is suitable for allowing quick access to the user's mouth to, for example, eat and/or drink without needing to remove the entire body of the mask. Further, the user's nostrils remain secured and protected beneath the remainder of the mask. The mouth panel may also be completely disconnected from the main body of the face mask to allow a user to eat and/or drink. Alternatively, the mouth panel may be partially disconnected from the mask by being rotated to the left, to the right or upward to allow a user to eat and/or drink.
