Problems solved by technology

[0008] However, when the needle is punctured by the rotational force of the capsule endoscope generated by the external rotating magnetic field, there may be a problem that if the external rotating magnetic field is continuously applied while the needle is piercing the intestinal wall, the needle will be punctured. And the capsule endoscope stops rotating, so that the capsule endoscope cannot follow the rotation of the external rotating magnetic field and presents an out-of-step state. When the external rotating magnetic field continues to rotate, the capsule endoscope will rotate in the opposite direction causing needle is pulled out

Embodiment approach 1

[0067] First, Embodiment 1 of the present invention will be described. figure 1 It is a schematic diagram showing the overall configuration of the capsule medical device system according to Embodiment 1 of the present invention. Such as figure 1 As shown, the capsule medical device system 1 in the first embodiment includes a capsule endoscope 10 as a capsule medical device, which is introduced into the body cavity of the subject by being swallowed through the subject's mouth, and communicate with an external device; and a magnetic field generating unit 2 as a rotating magnetic field generating device, which is installed around the subject and can generate a desired rotating magnetic field in three-dimensional directions. In addition, the capsule medical device system 1 further includes: a transceiver unit 3 that performs wireless communication with the capsule endoscope 10, receives wireless signals including images captured by the capsule endoscope 10, and transmits An op...

Embodiment approach 2

[0090] Next, Embodiment 2 of the present invention will be described. In the first embodiment described above, the rotation angle detection unit 33 detects the rotation of the capsule endoscope 10 based on the in-vivo image acquired by the capsule endoscope 10, but in the second embodiment, the rotation of the capsule endoscope 10 can be directly detected from the outside Rotation of type endoscope 10.

[0091] Figure 13 It is a schematic cross-sectional view showing the configuration of a capsule endoscope 10a used in the capsule medical device system according to Embodiment 2 of the present invention. Such as Figure 13 As shown, the capsule endoscope 10a has a magnetic field emitting unit that emits a magnetic field in an external direction, specifically, a magnetic field generating coil 40 that generates a magnetic field in the radial direction of the capsule endoscope 10a. The other structures are the same as those of the capsule endoscope 10, and the same reference n...

Embodiment approach 3

[0097] Next, Embodiment 3 of the present invention will be described. In the first embodiment described above, the rotation angle detection unit 33 detects the rotation of the capsule endoscope 10 based on the in-vivo image acquired by the capsule endoscope 10, but in the third embodiment, the The mirror 10 itself directly detects the rotation of the capsule endoscope 10 and transmits rotation information.

[0098] Figure 16 It is a schematic cross-sectional view showing the configuration of a capsule endoscope 10b used in the capsule medical device system according to Embodiment 3 of the present invention. Such as Figure 13 As shown, the capsule endoscope 10b has a gyro sensor 50 for detecting the rotation angle of the capsule endoscope 10b itself. The gyro sensor 50 functions as rotation angle detection means. In addition, the control unit 51 corresponding to the control unit 17 controls to transmit the rotation angle acquired by the gyro sensor 50 to the outside. The...

Abstract

When a capsule medical apparatus that has been introduced into a body is rotated by a rotating magnetic field for a desired three-dimensional rotation to puncture a needle of the capsule medical apparatus into a luminal surface, a step-out operation detecting unit detects the step-out operation that the capsule medical apparatus inversely rotates at a rotating speed larger than a rotating speed of the rotating magnetic field after the rotation of the capsule medical apparatus stops, and controls a rotating magnetic field generation apparatus that generates the rotating magnetic field on the basis of a detection result by the step-out operation detecting unit.

Description

technical field [0001] The present invention relates to a capsule medical device system capable of rotating a capsule medical device introduced into a living body to puncture a desired lumen surface with a needle and inject a medical solution into an affected part. Background technique [0002] In recent years, a swallowable capsule-type endoscope has been developed in the field of endoscopy. The capsule endoscope has the following functions: it has an imaging function and a wireless function. In order to observe the inside of the body cavity, the capsule endoscope is used, for example, in the esophagus, stomach, The insides of organs such as the small intestine move with their peristaltic movements and are photographed sequentially. In recent years, as such a capsule endoscope, a capsule endoscope has been proposed in which a needle connected to a drug solution tank and an actuator for protruding the needle are provided, and the needle can be protruded to the lesion. Inje...
