Abstract
An apparatus for insertion into the human body and which comprises one or more optionally scanning transducers 17,18 and a needle guide 12, which can be operated from the outside. The needle guide 12 is used for collecting tissue samples from the human body. According to the invention the needle guide 12 is separate from the other part of the apparatus which for hygienic reasons is covered by a sterile sheath 14. The needle guide 12 is thus attached to the other part of the catheter via the sheath. In other words the needle guide 12 is arranged outside the sheath 14 in such a manner that the needle need not penetrate the sterile sheath 14, which otherwise would entail that the apparatus should be disinfected after use.
