[0041] The mode for implementing the present disclosure (hereinafter referred to as "embodiment") will be described in detail with reference to the accompanying drawings. Note that the following embodiments are not limitations of the present disclosure. In addition, each of the drawings mentioned in the following description merely schematically describes the shape, size, and positional relationship so that the content of the present disclosure can be understood. In other words, the present disclosure is not limited to the shape, size, and positional relationship illustrated in each of the drawings. In addition, in the description of the drawings, the same parts are represented by the same figure marks and described.

[0042] [Overall Configuration of Endoscope Device]

[0043] Figure 1 is a diagram depicting the overall configuration of an endoscope device according to an embodiment.

[0044] Figure 1 The endoscope device 1 shown is a device used in the medical field and is used to treat biomedical tissues (e.g., incisions, etc.) while observing the inside of a living body. Figure 1 As shown, the endoscope device 1 includes an electric resectoscope 2, an endoscopic imaging device 3, a display device 4 and a controller 5.

[0045] [Configuration of resectoscope]

[0046] The resectoscope 2 is inserted into a living body and can take images of the subject and perform treatment of biomedical tissue. Figure 1 As shown, the resectoscope 2 includes a sheath 21 , a catheter 22 , an endoscope 23 , a resection electrode member 24 and a handle 25 .

[0047] The sheath 21 is a part having a cylindrical shape and inserted into a living body. The outer diameter of the catheter 22 is smaller than the inner diameter of the sheath 21, and is inserted through the sheath 21. The catheter 22 has a tip side ( Figure 1 The tip side is connected to the left side of the image by the attachment member 221 ( Figure 1 ) is fixed to the sheath 21. Here, the attachment member 221 is provided with a water supply port 222 through which liquid is injected into the sheath 21, and the liquid is delivered from the tip of the sheath 21.

[0048] The endoscope 23 is a portion for capturing an image of a subject, and includes an insertion portion 231 and an eyepiece portion 232. Figure 1 shown.

[0049] The insertion part 231 is fixed in the catheter 22, and is inserted through the sheath 21. An optical system is provided in the insertion part 231, the optical system including one or more lenses and focusing an image of a subject.

[0050] The eyepiece portion 232 is connected to the base end ( Figure 1 The eyepiece portion 232 is provided with an eyepiece optical system 2321, through which an object image gathered by the optical system in the insertion portion 231 is emitted to the outside from the eyepiece portion 232. The eyepiece portion 232 is formed in a tapered shape whose diameter increases toward the right side, and the endoscope imaging device 3 is detachably connected to the diameter-enlarged portion.

[0051] Here, the eyepiece section 232 is provided with a light source connector 2323 for connecting the light guide 2322. In other words, the light provided from the light guide 2322 of the light source device (omitted from the illustration) is supplied to the insertion section 231 through the eyepiece section 232. The light supplied to the insertion section 231 is emitted from the tip of the insertion section 231 and applied to the inside of the living body. The light (object image) applied to the inside of the living body and reflected by the inside of the living body is emitted from the eyepiece section 232 through the optical system in the insertion section 231 and the eyepiece optical system 2321.

[0052] The cutting electrode member 24 is inserted through the sheath 21 by the attachment member 221, and its tip protrudes from the tip of the sheath 21. The cutting electrode member 24 has a tip portion that contacts with a biomedical tissue, and treats the biomedical tissue by a high-frequency current.

[0053] The handle 25 is a part that allows doctors to hold the resectoscope 2 and operate the cutting electrode member 24. Figure 1 As shown, the handle portion 25 includes a fixing ring 251 , a sliding portion 252 and a spring member 253 .

[0054] The fixing ring 251 is a portion on which a doctor or the like places his or her thumb, and is fixed to the catheter 22 .

[0055] The slider 252 allows the catheter to be inserted therein and pass therethrough, and is configured to be able to move along the catheter 22. Figure 1 Move in the left and right directions. Figure 1 As shown in FIG. 2 , the cutting electrode member 24 is fixed to the sliding portion 252. In other words, the cutting electrode member 24 moves along the inner surface of the sheath 21 as the sliding portion 252 moves. Figure 1 The slide 252 is provided with a power connector 2522 for connecting a high-frequency power line 2521 (omitted from the illustration) connected to a high-frequency power source. The power connector 2522 is electrically connected to the cutting electrode member 24 via a wire (omitted from the illustration). Figure 1 As shown, the slide portion 252 is provided with a finger hooking member 2523 for a doctor or the like to hook a finger other than the thumb and move the slide portion 252 (advance or retract the cutting electrode member 24).

[0056] The spring member 253 is substantially U-shaped, one end of which is attached to the fixing ring 251, and the other end of which is attached to the sliding portion 252. The spring member 253 biases the sliding portion 252 toward the side away from the fixing ring 251. In other words, the doctor or the like hooks his or her finger on the fixing ring 251 and the finger hooking member 2523, and pulls against the biasing force of the spring member 253 close to the finger hooking member 2523, thereby biasing the sliding portion 252 toward the fixing ring 251. Figure 1 The right side moving sliding part 252 in Figure 1 On the other hand, when the doctor or the like removes his or her finger from the finger hooking member 2523, the sliding portion 252 (cutting electrode member 24) moves to the right by the biasing force of the spring member 253. Figure 1 Move to the left in.

[0057] The endoscopic imaging device 3 is detachably connected to the eyepiece portion 232 of the resectoscope 2 (endoscope 23). Under the control of the controller 5, the endoscopic imaging device 3 images the object image taken by the endoscope 23 (the object image emitted from the eyepiece portion 232) and outputs an image signal (raw signal) obtained by the imaging. The image signal is, for example, an image signal of 4K or larger. Note that the detailed configuration of the endoscopic imaging device 3 will be described later.

[0058] The display device 4 includes a display using liquid crystal, organic EL (Electro Luminescence), etc. Under the control of the controller 5 , the display device 4 displays an observation image based on a video signal from the controller 5 .

[0059] The controller 5 includes a memory and a processor, for example, hardware of an FPGA (field programmable gate array) or a CPU (central processing unit). The controller 5 integrally controls the operation of the endoscopic imaging device 3, the display device 4, and a power supply device (omitted from the illustration). For example, the controller 5 applies predetermined image processing to an image signal (raw signal) output from the endoscopic imaging device 3 to generate a video signal for display, and causes the display device 4 to display an observation image based on the video signal.

[0060] [Endoscope camera configuration]

[0061] Next, the detailed configuration of the endoscope camera head 6 will be described. Figure 1 As shown, an endoscope camera head 6 and a cable 7 are provided.

[0062] The endoscope camera head 6 is a part that is detachably connected to the eyepiece portion 232. Figure 1 As shown, the endoscope camera head 6 includes a housing 8 , a mounting member 9 (coupler), a prism 10 , a lens unit 11 , and an imaging section 12 .

[0063] The housing 8 is a casing that accommodates the prism 10 , the lens unit 11 , and the imaging section 12 therein.

[0064] The mounting member 9 has a bottom cylindrical shape inside, in which the eyepiece portion 232 can be mounted. The mounting member 9 is restricted from moving relative to the housing 8 in the direction of the first axis L1, and can rotate relative to the housing 8 around the first axis L1. Note that the detailed configuration of the mounting member 9 will be described later.

[0065] The prism 10 is disposed on the first axis L1 and the housing inner optical axis L2, and deflects the propagation direction of the object image captured by the endoscope 23. Specifically, the prism 10 deflects the propagation direction of the object image emitted from the eyepiece portion 232 and entering the housing 8 through an optical member (omitted from the illustration) by approximately 90°, so that the object image propagates along the housing inner optical axis L2.

[0066] The lens unit 11 is disposed on the optical axis L2 in the housing. The lens unit 11 includes one or more lenses, and forms an object image on an imaging plane of the imaging section 12 through the prism 10. In addition, the lens unit 11 is provided with an optical zoom mechanism (omitted from the illustration) for changing the viewing angle by moving one or more lenses, a focusing mechanism (omitted from the illustration) for changing the focus, etc. under the control of the controller 5 or the operation section 13.

[0067] The imaging section 12 is arranged on the optical axis L2 in the housing. In addition, the imaging section 12 images the object image formed by the lens unit 11 under the control of the controller 5. The imaging section 12 includes a sensor chip in which: an imaging member (omitted from the illustration), for example, a CCD (charge coupled device) or a CMOS (complementary metal oxide semiconductor) for receiving the object image formed by the lens unit 11 and converting it into an electrical signal is integrally formed; a signal processing section (omitted from the illustration) for performing signal processing (A / D conversion, etc.) on the electrical signal (analog signal) from the imaging member to output an image signal, etc., and outputs the image signal (original signal (digital signal)) obtained after the A / D conversion. Note that the above-mentioned signal processing section may not be integrally formed with the imaging member, and may be a separate body.

[0068] Therefore, the endoscope camera head 6 is configured to be rotatable with respect to the eyepiece portion 232 of the endoscope 23 through the mounting member 9 about the first axis L1. Figure 1 ) is located at a position deviated from the first axis L1 (the rotation center axis of the eyepiece portion 232). In addition, the endoscope camera head 6 rotates around the first axis L1 regardless of the rotation of the resectoscope 2 around the first axis L1, and is configured so that the optical axis L2 in the housing provided in the housing 8 is usually in a posture along the vertical direction (a posture in which the center of gravity O is located on the lower side of the first axis L1).

[0069] One end of the cable 7 is detachably connected to the controller 5 via the connector CN1, and the other end of the cable 7 is detachably connected to the endoscope camera 6 via the connector CN2. The cable 7 transmits the image signal output from the endoscope camera 6 to the controller 5, and transmits the control signal, synchronization signal, clock, power, etc. output from the controller 5 to the endoscope camera 6. Note that the transmission of the image signal from the endoscope camera 6 to the controller 5 via the cable 7 may be the transmission of the image signal in the form of an optical signal, or may be the transmission of the image signal in the form of an electrical signal. This also applies to the transmission of the control signal, synchronization signal, and clock from the controller 5 to the endoscope camera 6 via the cable 7. In addition, as Figure 1 As shown, the cable 7 is provided with an operating unit 13 which accepts various operations by a doctor or the like (for example, instructions for adjusting the image quality of an observed image (white balance adjustment, brightness adjustment, etc.), instructions for changing the viewing angle or focus of the lens unit 11, etc.).

[0070] [Detailed configuration of installation components]

[0071] Next, the detailed configuration of the mounting member 9 will be described.

Figure 5 This is an exploded perspective view of the mounting member 9 as seen from the front. Figure 6 is an exploded perspective view when the mounting member 9 is viewed from the rear side. Figures 2 to 6 In order to simplify the description of the mounting member 9, the housing 8 connected to the mounting member 9 and the optical member accommodated in the mounting member 9 are omitted.

[0073] like Figures 2 to 6 As shown, the mounting member 9 includes a first member 91 , a second member 92 , and a restricting member 93 .

[0074] [Configuration of the first component]

[0075] First, the detailed configuration of the first member will be described.

[0076] Figure 7 3 is a front view of the first member 91 . Figure 8 It is a rear view of the first member 91. Fig. 9 It is a side view of the first member 91.

[0077] like Figures 2 to 6 and Figures 7 to 9 As shown, the first member 91 is provided in the endoscope camera head 6 having the imaging portion 12. Specifically, the first member 91 is a member for attaching the mounting member 9 to the housing 8, and is a member for supporting the rotation of the second member 92. The first member 91 includes a first body portion 911, a second body portion 912, a third body portion 913, a fourth body portion 914, and a fifth body portion 915. The first body portion 911, the second body portion 912, the third body portion 913, the fourth body portion 914, and the fifth body portion 915 are integrally formed by resin molding or the like.

[0078] The first main body 911 has a tubular shape with an inner diameter R1 centered on the first axis L1. An optical member (omitted from the illustration) is accommodated in the first main body 911. The first main body 911 has a first opening 9111 and a second opening 9112 at opposite positions of a side surface orthogonal to the first axis L1. The opening sizes of the first opening 9111 and the second opening 9112 are different from each other.

[0079] The second body portion 912 is provided to extend in an annular shape with the first axis L1 as the center, and has an inner diameter R2. In addition, the outer diameter R12 of the second body portion 912 is larger than the outer diameter R11 (R11 <R12)。

[0080] The third main body portion 913 is arranged to extend in an annular shape about the first axis L1 and has an inner diameter R2. The outer diameter R13 of the third main body portion 913 is larger than the outer diameter R12 of the second main body portion 912 (R11 < R12 < R13). The third main body portion 913 has a contact surface 9131 that contacts the back surface 9210a of the bottom portion 9210 of the second member 92, which will be described later, in the direction of the first axis L1 ( Fig. 9 the left side in). Note that in one embodiment, the contact surface 9131 serves as the first rotational sliding surface.

[0081] The fourth main body portion 914 is arranged to extend in an annular shape about the first axis L1 and has an inner diameter R2. The outer diameter R14 of the fourth main body portion 914 is smaller than the outer diameter R11 of the first main body portion 911. Additionally, the fourth main body portion 914 is formed such that the length W1 in the direction of the first axis L1 is approximately equal to the length W11 of the spacer portion 9213 provided on the back surface 9210a side of the bottom portion 9210 of the second member 92, which will be described later.

[0082] The fifth main body portion 915 is arranged to extend in an annular shape about the first axis L1 and has an inner diameter R2. The outer diameter R15 of the fifth main body portion 915 is smaller than the outer diameter R11 of the first main body portion 911 but larger than the outer diameter R14 of the fourth main body portion 914 (R14 < R15 < R11). Additionally, the fifth main body portion 915 is formed such that the length W2 in the direction of the first axis L1 is approximately equal to the thickness W10 of the bottom portion 9210 of the second member 92, which will be described later. Further, the fifth main body portion 915 has a threaded groove portion 9152 on the outer peripheral side of the top end portion 9151 that can be threadedly engaged with a restricting member 93, which will be described later.

[0083] [Configuration of the Second Member]

[0084] Next, the detailed configuration of the second member 92 will be described.

[0085] Fig.10 is a front view of the second member 92. Fig.11 is a rear view of the second member 92. Fig.12 is a side view of the second member 92.

[0086] As Figures 2 to 6 and Figures 10 to 12 shown, the second member 92 can rotate about the first axis L1 passing through the first member 91, and the endoscope 23 can be connected to the first member 91. The second member 92 has a tubular portion 921 and a pressing portion 922.

[0087] The tubular portion 921 has a bottom tubular shape in which the eyepiece portion 232 can be installed. The tubular portion 921 has a disk-shaped bottom portion 9210 and a wall portion 9220 extending from an outer edge of the bottom portion 9210 toward the front side along the first axis L1.

[0088] The thickness W10 of the bottom portion 9210 along the first axis L1 is approximately equal to the thickness W2 of the fifth body portion 915 of the first member 91. In addition, the bottom portion 9210 has a contact portion 9211, a slot 9212, and a spacing portion 9213.

[0089] The inner diameter R21 of the contact portion 9211 is approximately equal to the outer diameter R30 of the limiting member 93 described later. In addition, the contact portion 9211 is formed with a through hole 9211a that penetrates the contact portion 9211 from the front to the back and has a circular planar shape, whose inner diameter R20 is approximately equal to the outer diameter R14 of the fourth main body portion 914 of the first member 91, and the contact portion 9211 is rotatable in a state where the first member 91 is inserted into the through hole 9211a. In addition, the contact portion 9211 has at least one cutout 9211b formed to be cut from the outer peripheral side of the through hole 9211a toward the outer edge side of the contact portion 9211; and an end portion 9211c, the front side of which is in contact with the back side of the limiting member 93.

[0090] The cutouts 9211b are arranged at a plurality of positions, for example, five positions, at predetermined angular intervals with the first axis L1 as the center. The cutouts 9211b have been subjected to R processing so as to be rounded toward the outer edge side of the bottom portion 9210. In addition, as Fig.13 As shown, the cutout 9211b may be such that an end surface 9211d of an end portion 9211c of the cutout 9211b is tapered to be inclined toward the rotation direction S1 of the second member 92. Note that, in addition to the tapered shape, the end portion 9211c may be such that the front side of the end portion 9211c has a shape inclined at a certain angle toward the rotation direction S1 of the second member 92 or a circular shape. Furthermore, in one embodiment, the cutout 9211b serves as a second cutout.

[0091] The slit 9212 extends in the shape of a circular arc with the first axis as the center, and penetrates from the front side to the back side. The slit 9212 is provided at a plurality of positions, for example, four positions, at predetermined intervals in the bottom portion 9210.

[0092] The spacers 9213 are provided in a plurality of numbers on the back surface 9210a side of the contact portion 9211 of the bottom portion 9210. Specifically, the spacers 9213 are provided at predetermined intervals on the back surface 9210a side of the bottom portion 9210 and the back surface side of the contact portion 9211 at, for example, five positions along the circumferential direction of the second member 92. The spacers 9213 protrude to the back surface side along the first axis L1 and are formed in a hemispherical shape.

[0093] When the endoscope 23 is connected to the second member 92, the pressing portion 922 presses the endoscope 23 toward the first axis L1. The pressing portion 922 has such elasticity that it can move in a direction approaching or moving away from the first axis L1 of the mounting member 9, and contacts the outer peripheral surface of the eyepiece portion 232 mounted inside the mounting member 9 to press the eyepiece portion 232 toward the bottom portion 9210 of the mounting member 9. The pressing portion 922 has a pressing member 9221, an elastic member 9222, and a supporting member 9223.

[0094] The pressing member 9221 is movably inserted into each of four holes 9220 a provided in the wall portion 9220 as an object rotated 90° around the first axis L1 of the mounting member 9 .

[0095] The elastic member 9222 includes a bent leaf spring or the like, and is mounted to the wall portion 9220 via a support member 9223. The elastic member 9222 biases the pressing member 9221 toward the first axis L1 of the mounting member 9, and the pressing member 9221 contacts both end portions 9222a of the elastic member 9222.

[0096] The supporting member 9223 applies a pressing force given from the outside toward the first axis L1 of the mounting member 9 on the elastic member 9222, whereby the elastic member 9222 expands to the outer peripheral side of the wall portion 9220 and the bias of the elastic member 9222 to the pressing member 9221 is offset. As a result, the eyepiece portion 232 can be easily detached from the mounting member 9.

[0097] [Restriction component configuration]

[0098] Next, the detailed configuration of the restriction member 93 will be described.

[0099] Fig.14 1 is a front view of the restricting member 93 . Fig.15 It is a rear view of the restriction member 93. Fig.16 It is a side view of the restriction member 93.

[0100] like Figures 2 to 6 and Figures 14 to 16As shown, the restricting member 93 restricts the second member 92 from moving in the direction of the first axis L1 by clamping the second member 92 with the first member 91 in a rotationally-permissible manner. The restricting member 93 has a body portion 931 and a flange portion 932. The body portion 931 and the flange portion 932 are integrally formed.

[0101] The main body portion 931 has a tubular shape centered on the first axis L1, and has an inner diameter R31 approximately equal to the outer diameter R14 of the fourth main body portion 914 of the first member 91. In addition, the thickness W31 of the main body portion 931 along the first axis L1 direction is approximately equal to the thickness W10 of the bottom portion 9210. The main body portion 931 is assembled to the fourth main body portion 914. In addition, the main body portion 931 is provided with a thread groove 9311 on its inner circumferential side.

[0102] The outer diameter R30 of the flange portion 932 is approximately equal to the inner diameter R21 of the contact portion 9211. The flange portion 932 has at least one notch 9321 and a notch 9322 formed to expose a portion of the end portion 9211c in contact with the second member 92 to the outside. Note that in one embodiment, the notch 9321 is used as a first notch.

[0103] The cutout 9321 is formed by cutting from the outer edge side toward the first axis L1. Note that the end surface 9321b of the end 9321a of the cutout 9321 may be formed into a tapered shape inclined toward the rotation direction of the second member 92, or may be formed into a shape formed at a predetermined angle or a circular shape.

[0104] The mounting member 9 configured in this manner restricts the second member 92 from moving in the direction of the first axis by clamping the second member 92 by the first member 91 in a manner that allows rotation by the restricting member 93. In addition, the mounting member 9 is configured so that the cutout 9321 (first cutout) of the restricting member 93 exposes a portion (end portion 9211c) of the contact portion 9211 of the second member 92 clamped by the first member 91 to the outside. In addition, as Fig.17 As shown in FIG. 1 , in a state where the second member 92 is rotated, the mounting member 9 is configured so that, when the cutout 9211b of the second member 92 and the cutout 9321 of the limiting member 93 overlap each other, the end 9321a of the cutout 9321 (first cutout) of the limiting member 93 and the end 9211c of the cutout 9211b (second cutout) of the second member 92 intersect with each other. For example, Fig.17As shown, in the state where the second member 92 is rotated, when the cutout 9211b of the second member 92 and the cutout 9321 of the limiting member 93 overlap each other, the mounting member 9 is configured so that the angle α formed between the cutout 9321 (straight line H1) of the limiting member 93 and the cutout 9211b (straight line H2) of the second member 92 is an acute angle. In other words, since the cutout 9321 of the limiting member 93 and the cutout 9211b of the second member 92 are both rotated (entered) by an angle relative to each other, the limiting member 93 and the second member 92 can be prevented from colliding with each other when rotating. As a result, the mounting member 9 has the second member 92 that rotates smoothly relative to the first axis L1.

[0105] In addition, if Fig.18 As shown, since the contact area between the spacer 9213 provided in the second member 92 and the contact surface 9131 of the first member 91 can be reduced to a minimum, the second member 92 can be smoothly rotated relative to the first axis L1.

[0106] [Cleaning of installation components]

[0107] Next, a method of cleaning the mounting member 9 will be described. FIG. 19A to FIG. 19C 1 is a diagram for schematically explaining the operation when the mounting member 9 is cleaned.

[0108] In such Fig.19A In the case where the second member 92 is rotated as shown (FIG. 19(A) → FIG. 19(B) → FIG. 19(C)), the contact portion 9211 of the second member 92 is exposed by the cutout 9321 of the limiting member 93 and the cutout 9321 of the second member 92 in sequence, and the cleaning liquid Q1 flows in, so that the contact portion 9211 of the second member 92 can be cleaned. In addition, since the edge of the contact portion 9211 of the second member 92 is also exposed, the edge portion can also be cleaned. In addition, since the cleaning liquid Q1 that has flowed in from the front side flows from the front side to the back side through the cutout 9321 of the limiting member 93 and the cutout 9211b of the second member 92, the cleaning efficiency can be improved.

[0109] According to one of the above-mentioned embodiments, the limiting member 93 has at least one cutout 9321, which is cut to expose a portion of the contact portion 9211 of the second member 92 clamped by the first member 91 to the outside, and the contact portion 9211 can be exposed to the outside only by the rotation of the second member 92, so the length of the cleaning time of the mounting member 9 can be shortened.

[0110] In addition, according to one embodiment, since the second member 92 is formed with the cutout 9211b, the cleaning liquid Q1 that has flowed in from the front side flows from the front side to the back side through the cutout 9321 of the limiting member 93 and the cutout 9211b of the second member 92, thereby improving the cleaning efficiency.

[0111] In addition, according to one embodiment, when the cutout 9211b of the second member 92 and the cutout 9321 of the limiting member 93 overlap with each other when the second member 92 is rotated, the end 9321a of the cutout 9321 of the limiting member 93 and the end 9211c of the cutout 9211b of the second member 92 intersect with each other, so that the second member 92 can rotate smoothly relative to the first axis L1.

[0112] In addition, according to one embodiment, since the tapered shape inclined toward the rotation direction S1 from the end surface 9211d of the end portion 9211c of the cutout 9211b of the second member 92 is provided, the second member 92 can smoothly rotate around the first axis L1.

[0113] Furthermore, according to one embodiment, since the spacer 9213 is provided on the back surface 9210 a side of the second member 92 , the second member 92 can smoothly rotate around the first axis L1 .

[0114] In addition, according to one embodiment, since the second member 92 is provided with at least one narrow groove 9212 extending in a circular arc form with the first axis L1 as the center, even when the cutout 9211b of the second member 92 and the cutout 9321 of the limiting member 93 overlap with each other when the second member 92 is rotated, the steam generated inside the mounting member 9 can be discharged to the outside.

[0115] Note that although the spacer 9213 has been provided on the back surface 9210 a side of the second member 92 in one embodiment, the spacer 9213 may be provided at, for example, the contact surface 9131 (first rotational sliding surface) of the first member 91 .

[0116] Furthermore, in the medical observation system according to one embodiment of the present disclosure, the term “unit” may be replaced by a “device” or a “circuit.” For example, the control unit may be replaced by a control device or a control circuit.

[0117] Although some embodiments of the present application have been described in detail based on the accompanying drawings, these are merely examples, and the present invention can be implemented not only through the embodiments described in the disclosure of the present invention but also through other modes obtained by various modifications or improvements based on the knowledge of those skilled in the art.
