  The imaging element 302 is mounted on an imaging substrate 305, and an optical system 306 such as an imaging lens is disposed on the front surface. An observation optical system 307 is configured by the illumination unit 301, the imaging element 302, the optical system 306, and the like. The imaging substrate 305 is mounted with a controller 308 for processing or controlling each unit on the back side.

  The capsule endoscope 300 includes a reed switch 309 that is turned on and off by an external magnetic field in order to control the driving of the capsule endoscope 300. In the storage state of the capsule endoscope 300, the capsule endoscope 300 is housed in a package including a permanent magnet that supplies an external magnetic field, and maintains an off state in an environment where a magnetic field of a certain intensity or more is applied. It has a structure that turns on when the strength of the magnetic field decreases. For this reason, in the state accommodated in the package, the capsule endoscope 300 is not driven.

  Furthermore, the capsule endoscope 300 includes a transmission device 311 with an antenna 310 that wirelessly outputs image information captured by the image sensor 302 to the outside on the back side of the battery 303.

  On the other hand, the indwelling device 200 for a capsule medical device is provided with a locking part 201 for fixedly placing the capsule endoscope 300 in a tissue in a body cavity at a desired site, and the locking part 201 is provided to provide a capsule-type medical device indwelling. A holding unit 202 for mounting and holding the endoscope 300. The locking portion 201 according to the first embodiment includes an endoscopic hemostatic clip 203 that is locked and fixed directly to a tissue in a body cavity by an endoscopic clipping treatment instrument. The clip 203 is a holding portion 202. Are connected by a shorter string member 204. In the first embodiment, two clips 203 and string members 204 are connected to different positions of the holding portion 202 and provided.

  The holding unit 202 has a structure that holds the capsule endoscope 300 integrally in a surface contact state with the outer peripheral surface of the capsule endoscope 300, and integrally holds the fitted capsule endoscope 300. More specifically, the holding portion 202 is formed in a shape including a substantially cylindrical portion having substantially the same radius as that of the capsule endoscope 300, and further on the distal end cover housing 304a side of the capsule endoscope 300. It is formed in a cap shape that covers the whole area except for the portion.

  Here, the holding and holding of the capsule endoscope 300 by the holding unit 202 is a method by press fitting, a method in which the capsule endoscope 300 is temporarily mounted by using a heat shrinkable tube or the like, and then contracted by applying heat, and an adhesive. Etc., etc. may be used for fixing and holding. In short, the existing capsule endoscope 300 can be attached, and the holding state in which the attached capsule endoscope 300 is not easily pulled out can be maintained in the body cavity for the monitoring time, and Any system and structure that can ensure the same swallowability (introduction into the body cavity) as the capsule endoscope 300 may be used. The holding unit 202 may be a material that does not impair the observation function, the transmission function, and the like of the capsule endoscope 300 and that does not interfere with the living body even if it is introduced and placed in a body cavity. Any of a hard member and a soft member may be sufficient, and any of a transparent member and an opaque member may be sufficient. Unlike the case of the capsule endoscope 300, there are few restrictions on the connection of the string member 204 to the holding portion 202 that does not include a built-in object, and the connection can be easily and firmly performed.

  The capsule indwelling medical device 100 including the capsule endoscope 300 attached and held in such an indwelling device 200 for a capsule medical device is placed in a desired position in the subject 400 and is received and fixed. A capsule indwelling medical system is configured by combining with the above. FIG. 2 is a schematic diagram illustrating a schematic configuration example of a wireless capsule indwelling medical system. As shown in FIG. 2, the wireless capsule indwelling medical system is introduced into a subject 400 and placed and fixed at a desired site in a body cavity such as the stomach 401 to capture an image of the stomach 401 in color. The capsule indwelling medical device 100 including the capsule endoscope 300 that wirelessly transmits data such as video signals to the receiving device 402 and the color image data wirelessly transmitted from the capsule endoscope 300 are received. A portable receiving device 402 and a display device 403 such as a portable viewer that displays a color image based on a video signal received by the receiving device 402 are provided. The receiving apparatus 402 includes a receiving antenna 404 attached to a part corresponding to the indwelling / fixed part of the capsule endoscope 300 on the external surface of the subject 400, for example, near the stomach 401.

  Thus, while using the general-purpose capsule endoscope 300 for the digestive tract, the capsule endoscope 300 is placed and fixed at a desired site in the body cavity as the capsule indwelling medical device 100, so that the capsule endoscope A desired part is imaged by 300, and the captured in-vivo image is observed by the display device 403, which is suitable for monitoring the affected area after surgery.

  Here, with reference to FIG. 3 to FIG. 4, a procedure of medical practice including an indwelling operation of the capsule endoscope 300 in the body cavity will be described in order. The introduction and placement of the capsule endoscope 300 into the body cavity is for monitoring the presence or absence of bleeding in the affected area after the endoscopic operation, and the endoscopic operation of the subject 400 to be processed. Done later. It should be noted that the capsule endoscope 300 may be introduced into the body cavity and placed before the endoscopic surgery, and the placement work may not be performed after the endoscopic surgery. In FIG. 4 etc., 405 shall show the operation part (for example, mucous membrane excision part) by endoscopic surgery. In addition, it is assumed that the receiving antenna 404 is attached to the outer surface of the subject 400 at an appropriate timing before and after the capsule endoscope 300 is introduced into the body cavity.

  First, as shown in FIG. 3, a general-purpose capsule endoscope 300 is prepared for the digestive tract, and the capsule endoscope 300 is fitted into the holding portion 202 to be integrated with the holding portion 202. . Then, the clip 203 connected to the holding unit 202 is assembled to a clipping treatment instrument 408 that is an endoscopic treatment instrument that protrudes from the forceps channel 407 of the endoscope 406. Then, by pulling the clip 203 and the clipping treatment instrument 408 into the forceps channel 407, the capsule endoscope 300 is temporarily fixed to the distal end portion of the endoscope 406 together with the holding portion 202.

  Next, as shown in FIG. 4A, the endoscope 406 is introduced into the body cavity through the oral cavity of the subject 400 in a state where the capsule endoscope 300 and the holding unit 202 are integrated. For example, after being introduced into the stomach 401 as a desired site, the clipping treatment instrument 408 is protruded again, and the capsule endoscope 300 held by the holding unit 202 is separated from the distal end of the endoscope 406.

  Then, as shown in FIG. 4B, by monitoring the captured image of the capsule endoscope 300 through the receiving device 402 and the display device 403, the surgical unit 405 to be monitored becomes the observation optical of the capsule endoscope 300. The clip 203 is locked and fixed to the tissue in the body cavity by the clipping treatment tool 408 while confirming whether the system 307 is positioned within the observation visual field. At this time, in the first embodiment, two clips 203 are prepared. After one of the clips 203 is locked in the body cavity, the captured image of the capsule endoscope 300 is monitored by the display device 403 and the remaining clips are used. By adjusting the locking portion 203, the indwelling posture of the capsule endoscope 300 can be adjusted.

  Thereafter, by pulling the endoscope 406 out of the body cavity, as shown in FIG. 4-3, the capsule endoscope 300 is placed and fixed at a desired site in the body cavity through the holding portion 202 and the clip 203 that are attached and held. The indwelling observation using the capsule endoscope 300 becomes possible.

  After the monitoring is finished, the clip 203 falls into the body cavity together with the holding portion 202 and the capsule endoscope 300 due to the necrosis of the tissue in the body cavity where the clip 203 is locked. It may be collected endoscopically through a collection net or the like while being integrated with the holding unit 202, or may be discharged out of the body cavity as it is.

  In this embodiment, an example in which the capsule endoscope 300 is introduced from the oral cavity and placed therein has been described. However, the present invention is not limited to the oral cavity, and the capsule endoscope 300 is introduced and placed through the anus or other opening, for example. The same can be applied to the case.

(Modification 1)
FIGS. 5-1 to 5-5 illustrate modifications of the locking portion. FIG. 5A shows that an endoscopic fixture such as an endoscopic hemostatic clip (not shown) is formed integrally with the holding unit 202 by projecting a part of the holding unit 202. Then, a modified example in which the hole 210 fixed to the tissue in the body cavity by the endoscopic treatment tool is used as the locking portion will be described. According to this modification, the structure is simple and the manufacture is easy.

  FIG. 5B is an illustration showing an endoscopic fixing tool provided in connection with the holding unit 202, for example, an endoscopic treatment tool such as a grasping forceps by using an endoscopic hemostatic clip 220. A modified example in which an annular string member 222 fixed to the tissue 221 is used as a locking portion is shown. According to this modification, the annular string member 222 may be simply connected in a ring shape, and the structure is simple and the manufacture is easy.

  In this case, for example, as shown in FIG. 5C, when a plurality of annular string members 222a to 222c as locking portions are provided and the sizes thereof are different, the clip 220 is used to lock the tissue 221 in the body cavity. Since the optimum annular string members 222a to 222c can be selected according to the shape of the tissue 221 in the body cavity near the desired site, it is easy to approach and the workability of the endoscopic treatment is improved.

  FIG. 5-4 illustrates an endoscopic fixture provided in connection with the holding unit 202, for example, an endoscopic treatment instrument such as a grasping forceps by using an endoscopic hemostatic clip 220. A modified example in which the mesh member 223 fixed to the tissue 221 is a locking portion is shown. According to this modification, since the mesh member 223 can be locked to the body cavity tissue 221 at an arbitrary position, locking and fixing by the clip 220 is facilitated, and the workability of the endoscopic treatment is improved. The same effect can be obtained when a cloth-like member or a sheet-like member is used instead of the net-like member 223.

  FIG. 5-5 illustrates a part of the body cavity tissue 221 that is formed integrally with the holding unit 202 by projecting a part of the holding unit 202 and is to be fixed by an endoscopic fixing tool, for example, the needle 230. The modification which made the suction part 231 for suction the latching | locking part is shown.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a cross-sectional structure diagram illustrating a configuration example of the capsule indwelling medical device according to the second embodiment. The capsule medical device indwelling apparatus 200 according to the second embodiment includes, for example, a holding part 240 formed in a substantially cylindrical shape having substantially the same radius as the capsule endoscope 300 and open at both ends. The distal end side of the holding portion 240 on the distal end cover housing 304 a side is formed to project as a hood portion 241 for the observation optical system 307 built in the capsule endoscope 300. The protrusion amount of the hood portion 241 is set so as not to enter the observation visual field of the observation optical system 307, that is, to be positioned outside the observation visual field. As the locking portion, the various configuration examples described above can be used, but here, for example, a configuration example using the clip 203 similar to the case of FIG. 1 is used.

  The capsule endoscope 300 captures an image in the body cavity by the observation optical system 307 through the transparent tip cover housing 304a portion, and is appropriate when dirt or the like occurs in the tip cover housing 304a portion serving as an observation window. An image cannot be obtained. In the case of indwelling observation for the purpose of monitoring the affected area after surgery, in general, since there is no intake of food or drink during the observation period, it is considered that the surface of the tip cover housing 304a is not very dirty due to food or drink. . However, a peristaltic motion is performed in the body cavity, and liquid such as body fluid may adhere to the surface of the tip cover housing 304a during long-term monitoring. Here, in the first embodiment, since the holding unit 240 includes the hood unit 241, the surface of the tip cover housing 304 a is prevented from being soiled in a state where the capsule endoscope 300 is left in the body cavity. In addition, even if the holding unit 240 is an opaque member, the observation optical system 307 does not interfere with the observation field of view, and good indwelling observation by the observation optical system 307 becomes possible.

  In particular, as shown in FIG. 7, when the capsule endoscope 300 is placed so as to perform the downward observation in the gravity direction in the stomach 401 or the like, a holding unit that integrally holds the capsule endoscope 300. Since 240 has a hood portion 241 on its tip (lower end) side, it is difficult for body fluid or the like to adhere to the surface of the tip cover housing 304a serving as an observation window, and contamination thereof can be prevented.

(Modification 2)
FIG. 8 is a cross-sectional structure diagram illustrating a configuration example of the capsule indwelling medical device according to the second modification. The hood portion 241 of the second modified example is for the capsule endoscope 300 in which the distal end side inner peripheral portion protrudes in the radial direction so as to match the shape of the outer surface of the distal end cover housing 304 a of the capsule endoscope 300. An abutting portion 242 is provided. That is, since the inner diameter of the abutting portion 242 is smaller than the outer diameter of the capsule endoscope 300, when the capsule endoscope 300 is fitted and attached to the holding portion 240 from the direction indicated by the arrow in FIG. The capsule endoscope 300 stops at a position where it abuts against the abutment portion 242 of the hood portion 241. Therefore, it is not necessary to align the holding unit 240 and the capsule endoscope 300, and the fitting and mounting work is simplified.

(Modification 3)
FIG. 9 is a cross-sectional structure diagram illustrating a configuration example of the capsule indwelling medical device according to the third modification. The holding part 250 of the third modification includes a hood part 251 formed of a transparent member. Even if the holding | maintenance part 250 is comprised entirely from the transparent member, only the food | hood part 251 part may be comprised from the transparent member. Such a hood portion 251 is formed so as to protrude to a position where the observation optical system 307 enters the observation field of view. More specifically, the capsule endoscope 300 is formed so as to protrude from the distal end portion of the distal end cover housing 304a, and is formed to be longer in the direction of gravity.

  According to the modified example 3, since the hood portion 251 is sufficiently long and covers the surface of the tip cover housing 304a significantly, it is difficult for body fluids or the like to adhere to it, and the dirt prevention effect can be enhanced. In this case, the length of the hood portion 251 is ensured by entering the observation visual field, but since the hood portion 251 is formed of a transparent member, the observation ability by the observation optical system 307 can be ensured.

(Modification 4)
FIG. 10 is a cross-sectional structure diagram illustrating a configuration example of the capsule indwelling medical device according to the fourth modification. The holding part 260 of the modification 4 includes a dome-shaped hood part 261 that is formed of a transparent member and covers the entire observation visual field of the observation optical system 307. Even if the holding part 260 is entirely composed of a transparent member, only the hood part 261 may be composed of a transparent member. Further, the holding portion 260 is formed with an abutting portion 262 corresponding to the abutting portion 242 so as to be positioned at a boundary portion with the hood portion 261. Further, a dirt prevention coating is applied to the outer surface of the hood portion 261, and a dirt prevention coating film 263 is formed. This antifouling coating is a water-repellent coating or a hydrophilic coating such as a photocatalyst, and can be properly used depending on the application (intentional purpose, location, etc.).

  According to the modified example 4, since the hood portion 261 covers the entire observation field (the front front surface of the distal end cover casing 304a), the surface of the distal end cover casing 304a of the capsule endoscope 300 is not soiled. Further, since the antifouling coating film 263 is formed on the outer surface of the hood portion 261 by the antifouling coating, the hood portion 261 itself is not easily contaminated, and there is little adverse effect on the observation optical system 307. In particular, if the surface position of the hood part 261 is set so as to be outside the depth of focus of the observation optical system 307 of the capsule endoscope 300, the observation optical system 307 becomes dirty even if the outer surface of the hood part 261 is somewhat dirty. Is not in focus, so the effect on observation can be minimized.

  The outer surface of the tip cover housing 304a of the capsule endoscope 300 can be coated with antifouling coating, but depending on the site to be applied, a water repellent coating or a hydrophilic coating is selected. Therefore, the versatility of the capsule endoscope 300 itself is impaired. On the other hand, if an antifouling coating is applied to the outer surface of the hood portion 261, whether the capsule endoscope 300 itself is a general-purpose one, is it a water repellent coating or a hydrophilic coating depending on the application? The choice of materials can be expanded.

(Modification 5)
FIG. 11 is a cross-sectional structure diagram illustrating a configuration example of the capsule indwelling medical device according to the fifth modification. The holding unit 260 of Modification 5 includes a dome-shaped hood 264 that has optical characteristics that function with respect to the observation optical system 307 in the configuration of Modification 4. In the modified example 5, as the optical characteristics, the angle of view and the depth of the image captured by the observation optical system 307 can be changed by appropriately adjusting the refractive index distribution and the curvature of the material of the hood portion 264. . In the illustrated example, an optical characteristic is provided so that the observation viewing angle is enlarged by adjusting the angle of view. According to the modified example 5, optical performance can be obtained in accordance with the purpose of placement of the capsule endoscope 300, and better monitoring observation can be performed.

(Embodiment 3)
A third embodiment of the present invention will be described with reference to FIG. FIG. 12 is a cross-sectional structure diagram illustrating a configuration example of the capsule indwelling medical device according to the third embodiment. The capsule medical device indwelling device 200 according to the third embodiment is formed by positioning a locking portion integral with the holding portion 270, for example, the hole 210 on the distal end cover housing 304a side of the capsule endoscope 300. At the same time, the hole 210 is configured to be within the observation field of view of the observation optical system 307.

  According to the third embodiment, since the hole 210 is also within the observation field of view, the engagement of the hole 210 can be determined by looking at the screen of the display device 403 during the locking and fixing operation of the clip or the like with respect to the hole 210. The fixed state can also be confirmed, and it can be securely locked. In addition, when monitoring the capsule endoscope 300 after indwelling and fixing, not only the target surgical site but also the state of the hole 210 can be monitored and monitored at the same time, so that the occurrence of dropout or the like can be detected quickly. Can do.

(Modification 6)
FIG. 13 is a perspective view illustrating a schematic configuration example of the capsule indwelling medical device 100 according to the sixth modification. In the holding unit 270 having the configuration according to the third embodiment, the deformation system 6 is also located on the same side as the hole 210 (on the same bus) on the rear side of the capsule endoscope 300 (back of the observation field). A hole 210a is provided as a stop. Note that the vicinity of the holes 210 and 210a is made of a flexible member in order to facilitate introduction into the body cavity.

  According to the modified example 6, the holding portion 270 to which the capsule endoscope 300 is attached and held is locked and fixed to the tissue in the body cavity by the two holes 210 and 210a in the longitudinal direction. The visual field of the mold endoscope 300 can be fixed reliably. In particular, when the hole 210a side is locked first, and then the locking operation on the hole 210 side is performed while the image captured by the capsule endoscope 300 is monitored by the display device 403, a desired part is obtained. The capsule endoscope 300 can be reliably fixed to the visual field.

  In this case, as shown in FIG. 14, a transparent hood portion 271 is detachably provided as a separate body with respect to the tip cover housing 304 a side portion of the capsule endoscope 300 of the holding portion 270. Also good. According to this, the hood part 271 can be dealt with by attachment or detachment according to a use or a part to be used.
