The aim of the invention is to improve a bone mill (20) that is used for comminuting a grinding material in the form of bones or bone material in such a way that the grinding material can be comminuted in a simple and careful manner. Said aim is achieved by the fact that the bone mill (20) comprises a receiving chamber (112) for the grinding material, a comminuting device (26), and an advancing element (32) for moving the grinding material in the direction of the comminuting device (26) within the receiving chamber (112) while the receiving chamber (112) is provided with an outlet (113) which is covered at least in part by the comminuting device (26). Furthermore, the receiving chamber (112) is movable relative to the comminuting device (26).

The invention relates to a surgical positioning instrument (1) for supporting and holding organs, comprising a preferably concave bearing portion (6) and a support portion (2) which is substantially rearward relative to the bearing portion. An organ which is to be positioned can be received via the bearing portion, and the surgical positioning instrument can be supported on an area surrounding the organ via the support portion. Furthermore, at least the bearing portion is designed to partly match a surface of the organ to be supported and to be dimensionally stable.

摘要:
The present application relates to a double valve for a surgical retractor, comprising a base body (1) that has an essentially cylindrical mounting pin (2) for mounting the double valve to a surgical retractor, and at least two valve elements (3a, 3b) that are arranged on the base body (1) such that they can be rotated and/or moved at least through a certain angle range relative to the base body (1). The present application further relates to a valve arrangement in which a double valve is connected to another double valve or a single valve via a connecting element. In this case, the at least one double valve and, optionally, the single valve can be rotated relative to the connecting element. The application additionally relates to a retractor comprising a double valve, a valve arrangement or a valve group that is composed of double valves and a valve arrangement.
