- the X-ray imaging apparatus 55 can also perform X-ray imaging by manual operation by staff such as an operator.
- the surgeon can grasp the insertion length of the guide tube inserted into the large intestine. Accordingly, the surgeon can perform the insertion operation using the insertion length as a guide when inserting the guide tube 21B to the cecum lOOg.
- the guide tube rotating device 22 By registering the insertion length of the guide tube 21B in advance, when inserting the guide tube 21B into the large intestine, the guide tube rotating device 22 can be stopped at a desired insertion length. This can prevent the guide tube 21B from being inserted into a deep part of the large intestine beyond a predetermined length. Therefore, a highly safe insertion device is realized.
- the operator can grasp the insertion state and the insertion shape of the guide tube 21 inserted into the large intestine from the X-ray image displayed on the monitor 54. Therefore, it is possible to easily confirm whether or not the guide tube 21 is smoothly inserted into the large intestine.
- the trans-bonder transmits radio waves.
- the present invention is not limited to radio waves, and it is sufficient if the detection unit can detect a magnetic field, light, sound, or the like.
- the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the gist of the invention.
