Problems solved by technology

However, as in the capsule endoscope described in Patent Document 1, when the needle is only protruded to the intestinal wall of the puncture target, the needle cannot be smoothly punctured into the target layer due to the curvature of the intestinal wall and the reaction of the intestinal wall in many cases. , cannot reliably inject liquid

Embodiment approach 1

[0081] Embodiment 1 will be described first. figure 1 It is a schematic diagram showing the overall configuration of the capsule introduction system according to the first embodiment. like figure 1 As shown, the capsule introduction system 1 of Embodiment 1 includes: a capsule endoscope 10 that is swallowed from the subject's mouth and introduced into the body cavity of the subject for communicating with an external device; The generating unit 2 is arranged around the subject and can generate a three-dimensional rotating magnetic field; the receiving unit 3 is used for wireless communication with the capsule endoscope 10 and receives information including the capsule endoscope 1 The wireless signal including the photographed image; the control unit 4, which is used to control each component part of the capsule introduction system 1; the display unit 5, which is used to display and output the image taken by the capsule endoscope 10; The input unit 6 is used to input instructi...

Embodiment approach 2

[0111] Next, Embodiment 2 will be described. Figure 16 It is a figure showing the internal structure of the capsule endoscope of Embodiment 2. In addition, the capsule introduction system of Embodiment 2 has the same figure 1 The same composition, by performing with Figure 5 The injection of the chemical solution can be performed in the same processing procedure as the one shown.

[0112] In the capsule introducing system of embodiment 2, such as Figure 16 As shown, a capsule endoscope 210 having a permanent magnet 218 whose magnetization direction is substantially parallel to the radial direction of a casing constituting the capsule endoscope is used. Since the radial direction of the capsule endoscope 210 coincides with the magnetization direction of the permanent magnet 218 inside the capsule endoscope 210, the radial direction of the capsule endoscope 210 can be changed along the direction of the applied magnetic field. Therefore, when a rotating magnetic field is a...

Embodiment approach 3

[0124] Next, Embodiment 3 will be described. Figure 21 It is a figure showing the internal structure of the capsule endoscope of Embodiment 3. in addition, Figure 22 Yes Figure 21 CC cutaway view. In addition, the capsule introduction system of Embodiment 3 has the same figure 1 The same composition, by performing with Figure 5 The injection of the chemical solution can be performed by the same processing procedure as the one shown.

[0125] In the capsule introducing system of embodiment 3, such as Figure 21 As shown, a capsule endoscope 310 including a permanent magnet 318 in which the radial direction of the casing is substantially parallel to the magnetization direction is used, as in the capsule endoscope 210 .

[0126] And, if Figure 21 and Figure 22 As shown, the driver 15 is connected at an angle of 90° to 135° to the rear end of the needle 316 . Therefore, driver 15 such as Figure 22 When moving toward the outer peripheral side of the capsule endosco...

Abstract

An introduction-into-subject system which is capable of making a reliable puncture of a needle in a layer subjected to puncture.A capsule endoscope (10) has the needle (16) which can project from the surface of a casing and can be housed under the surface and the capsule endoscope (10) has a permanent magnet (18). A magnetic field control part (8) controls a magnetic field generation part to generate a magnetic field which varies the direction of the permanent magnet (18) on the basis of the magnetization direction of the permanent magnet (18) at the capsule endoscope (10), the position of the needle (16) at the capsule endoscope (10), and the direction of the tip of the needle (16). Therefore, the magnetic field control part (8) varies the direction of the whole capsule endoscope (10) soas to make the puncture of the projecting needle (16) in the layer subjected to puncture. As the result of this, it is possible to reliably stick the needle (16) into the layer to be punctured.

Description

technical field [0001] The present invention relates to a subject body introduction system including a subject body introduction device to be introduced into a subject, and a control device that controls the operation of the subject body introduction device. Background technique [0002] In the field of endoscopes, swallowable capsule endoscopes have been developed. The capsule endoscope has an imaging function and a wireless communication function, and also has the following functions: after being swallowed by the patient from the mouth until it is naturally discharged from the human body, for example, along with the esophagus, stomach, small intestine, etc., in order to observe the inside of the body cavity The peristaltic movement of the internal organs moves inside the internal organs and is photographed sequentially. In recent years, as such a capsule endoscope, a capsule endoscope provided with a needle connected to a drug solution tank and an actuator for protruding ...
