Cerebral surgery apparatus

A cerebral surgery endoscope apparatus comprising:

• a stereotaxic instrument to be secured to the head of a patient to effect positioning of a treating instrument in an affected part;
• treating instrument inserting means whose inserting direction is determined by said stereotaxic instrument, for inserting treating instruments into the head of the patient;
• a telescope detachably inserted into said inserting means having a channel into which a treating instrument can be inserted and further having an insertable part to be inserted into said inserting means,
• said telescope and channel being removably inserted into said inserting means in a state that the longitudinal axis of the insertable part of said telescope and the longitudinal axis of said inserting means are substantially in parallel, and said treating instrument being removably insertable into said channel, and further
• said telescope and channel being removably insertable into said inserting means allowing supplying or draining of liquid through a cavity of said inserting means while said telescope is removably inserted into said inserting means;
• and
• a fixing device connected to said stereotaxic instrument to support and fix said inserting means and said telescope with respect to said stereotaxic instrument, a rear end of said inserting means extending to and operatively connecting with said fixing device, and an overall length of said inserting means being hollow.
