ENDOSCOPIC DEVICE FOR LOCOMOTION THROUGH THE GASTRO-INTESTINAL TRACT

摘要

front end (1b, 21b) and rear (1c, 21c) connected between one or more variable length an intermediate portion (1a, 21a) variable length prefix middle direction (A) to move the endoscope along the body cavity, including. First and second clamping means (7, 12, 27, 32) is at the front end and rear end for clamping a portion surrounding the inner wall of the steel body (P) to the respective shift integrally formed. When in the first and second clamping means is opened and the suction means to the body wall is formed teaching sufficient enough to be incorporated into the low pressure of the clamping (13, 14, 37, 38) of the first and second clamping It is connected to the means. While the wall portion (P) surrounding the first clamping means firmly fixed between the clamping means, and causing the rear end of the forward movement due to the middle portion shrinks, the wall portion (P) surrounding the second clamping means of the clamping means tight means for causing elongation and contraction of the middle portion to the synchronized operation to generate a forward motion due to the front end of the elongated middle portion and fixed while the means for operating the first and second clamping means between (6, 11, 26, 31) are provided.
