The distal (2036) edge and the proximal edge are included, the open part at the same time from the proximal edge in the distal (2036) edge (32) to extending the lumen which appears is demarcated the long flexible tube (12 ) with, the arrangement mechanism which is arranged in the distal (2036) edge of the flexible tube which is approached to the open part (35) being, in order the remedy instrument which passes through lumen (20) to transmit power, and in order the remedy instrument extending appears in order to control the direction which from the open part two in at least degree of freedom, to move, the medical device which has with the arrangement mechanism which is formed is disclosed. In several execution forms, arrangement mechanism has the rotary possible roller vis-a-vis the open part, the roller includes the lumen which passes through itself, lumen is formed exceeding lumen, in order distal (2036) extending to accommodate the remedy instrument which is put out.遠位端および近位端を含み、かつ近位端から遠位端における開口部(32)まで延出する内腔を画定する細長い可撓管(12’)と、開口部に近接する可撓管の遠位端に配置される配置機構(35)であって、内腔の中を通る治療器具(20)に力を伝達するため、および治療器具が開口部から延出する方向を制御するために、少なくとも2つの自由度において移動するように構成される配置機構とを備える医療装置が開示される。いくつかの実施形態において、配置機構は、開口部に対して回転可能なローラを備え、ローラは、自身の中を通る内腔を含み、内腔は内腔を越えて遠位に延出される治療器具を収容するように構成される。
