Embodiments for Carrying Out the Invention

[0010] Hereinafter, referring to the drawings, embodiments of the surgical microscope system, the auxiliary imaging device, and the surgical field imaging method of the present invention will be described.

[0011] [First Embodiment] FIG. 1 is a diagram showing an example of the surgical microscope system 1 of the first embodiment. In the example shown in FIG. 1, the surgical microscope system 1 of the first embodiment is used, for example, when performing a plastic surgery for forming a microvascular anastomosis in microsurgery. FIG. 2 is a diagram conceptually showing a microvascular anastomosis in microsurgery performed using the surgical microscope system 1 of the first embodiment. Specifically, the portion surrounded by the circle in FIG. 2 shows the surgical site (such as two microvascular BLs to be anastomosed in microsurgery) included in the surgical field imaged by the surgical microscope main body 11 shown in FIGS. 1 and 2.

[0012] In the examples shown in FIGS. 1 and 2, the surgical microscope system 1 of the first embodiment includes a surgical microscope main body 11, an auxiliary imaging device 12, a connection member 13, and an auxiliary display device 14. The surgical microscope main body 11 of the first embodiment is configured in the same manner as the surgical microscope described on the website indicated by the following URL, for example. https: / / www.leica-microsystems.com / jp / %E8%A3%BD%E5%93%81%E7%B4%B9%E4%BB%8B / %E6%89%8B%E8%A1%93%E7%94%A8%E9%A1%95%E5%BE%AE%E9%8F%A1 / https: / / www.medicaltown.net / neurosurgery / product / sms / orbeye / https: / / products.awi.co.jp / ja / medical / medical / equipment / id000172

[0013] In the examples shown in FIGS. 1 and 2, the surgical microscope main body 11 has an observation optical system 11A and a display device 11B. The observation optical system 11A has functions such as obtaining an image of the surgical field, changing magnification, focusing, etc. The observation optical system 11A includes, for example, an objective lens 11A1, an imaging device 11A2, etc. The objective lens 11A1 is disposed to face a surgical field including a surgical site such as two microvessels BL (see FIG. 2) anastomosed in microsurgery. The imaging device 11A2 converts the light of the surgical field that enters the observation optical system 11A through the objective lens 11A1 into digital image data and outputs it. That is, the imaging device 11A2 images the surgical field through the objective lens 11A1. That is, the observation optical system 11A plays a role of projecting the surgical field by an optical system such as the objective lens 11A1 and guiding the projected image of the surgical field to the imaging device 11A2.

[0014] The display device 11B has the function of displaying an image of the surgical field corresponding to the digital image data of the surgical field generated by the image sensor 11A2. The display device 11B includes, for example, an image presentation unit 11B1, an eyepiece unit 11B2, and a display 11B3. The image presentation unit 11B1 presents an image of the surgical field corresponding to the digital image data of the surgical field generated by the image sensor 11A2 to the surgeon's eyes via the eyepiece unit 11B2. The display 11B3 displays an image of the surgical field corresponding to the digital image data of the surgical field generated by the image sensor 11A2. The surgeon can confirm the image of the surgical field via the eyepiece unit 11B2, and can also confirm the image of the surgical field using the display 11B3. The display 11B3 is also used by surgical assistants, scrub nurses, etc., to confirm the image of the surgical field. In the example shown in Figure 1, the surgical microscope body 11 is equipped with a display 11B3, but in other examples, the surgical microscope body 11 may not be equipped with a display 11B3.

[0015] In the examples shown in Figures 1 and 2, the auxiliary imaging device 12 includes, for example, an imaging unit 12A, an illumination unit 12B, a housing unit 12C, an interface unit 12D, and the like. The imaging unit 12A images the surgical area (such as two microvessels BL to be anastomosed in microsurgery) included in the surgical field imaged by the surgical microscope body 11, at a different angle from the surgical microscope body 11. The illumination unit 12B illuminates the surgical area imaged by the imaging unit 12A with illumination light. The housing unit 12C houses the imaging unit 12A and the illumination unit 12B. The interface unit 12D has the function of transmitting image data of the surgical site captured by the imaging unit 12A to the auxiliary display device 14. The interface unit 12D is composed of, for example, a USB (Universal Serial Bus) cable. The auxiliary display device 14 displays images of the surgical site (two microvessels BL to be anastomosed in microsurgery) captured by the imaging unit 12A at a different angle from the surgical microscope body 11. In the examples shown in Figures 1 and 2, the image data of the surgical area captured by the imaging unit 12A is transmitted to the auxiliary display device 14 via an interface unit 12D, which is configured as a USB cable or the like. However, in other examples, the image data of the surgical area captured by the imaging unit 12A may be transmitted to the auxiliary display device 14 via an interface unit 12D that has wireless communication capabilities.

[0016] In the examples shown in Figures 1 and 2, the surgeon can confirm the surgical field through the eyepiece 11B2 as described above, and can also confirm the surgical site (such as the two microvessels BL anastomosed in microsurgery) from a different angle than the surgical microscope body 11 by using the auxiliary display device 14. The auxiliary imaging device 12 is configured similarly to the ear scope, ear pick camera, etc., described on the website shown at the URL below. https: / / www.amazon.co.jp / dp / B08Y8893B2?tag=sl01tn-22&linkCode=osi&th=1&psc=1 https: / / www.eselect-ec.jp / category / select / pid / 9190 https: / / buy.sympheia.shop / bellarmine / jdMcJBemeE.html https: / / www.biccamera.com / bc / item / 5915548 /

[0017] The connecting member 13 connects the surgical instrument ST, which is held by the surgeon, to the auxiliary imaging device 12. As shown in Figure 2, when microvascular anastomosis is performed in microsurgery, the needle holder ST2, which serves as a surgical instrument ST, is held by the surgeon's dominant hand. The needle holder ST2 grasps the suture needle ND to which the suture thread SR is attached. Furthermore, when microvascular anastomosis is performed in microsurgery, the forceps ST1, which serve as surgical instruments ST, are held by the surgeon's non-dominant hand. The forceps ST1 are fixed by clips CP and are used to grasp one of the two microvascular vessels BL that are to be sutured with suture threads SR.

[0018] Figures 3 and 4 show an example of the forceps ST1 and connecting member 13 in a state where the connecting member 13 is attached to the forceps ST1. In detail, Figures 3(A) and 4(A) correspond to views of the forceps ST1 and connecting member 13 from above (i.e., from the objective lens 11A1 of the surgical microscope body 11), and Figures 3(B) and 4(B) correspond to views of the forceps ST1 and connecting member 13 from below Figures 3(A) and 4(A). Figure 3 is a diagram illustrating an example of each part of the forceps ST1 and connecting member 13, and Figure 4 is a diagram illustrating an example of the dimensions of the forceps ST1 and connecting member 13. Figure 5 shows an example of the housing portion 12C of the auxiliary imaging device 12, the connecting member 13, and the forceps ST1 of the auxiliary imaging device 12 in a connected state. More specifically, Figure 5(A) corresponds to a view of the housing portion 12C, connecting member 13, and forceps ST1 of the auxiliary imaging device 12 from above (i.e., from the objective lens 11A1 of the surgical microscope body 11), and Figure 5(B) corresponds to a view of the housing portion 12C, connecting member 13, and forceps ST1 of the auxiliary imaging device 12 from below Figure 5(A). In the examples shown in Figures 1 to 5, the forceps ST1 include a first part ST11 and a second part ST12. The first part ST11 corresponds to the thumb of the surgeon's non-dominant hand (i.e., the hand that does not hold the needle holder ST2). The second part ST12 corresponds to the index finger of the surgeon's non-dominant hand. In other words, in the examples shown in Figures 1 to 5, the practitioner's right hand is dominant, and their left hand is non-dominant.

[0019] In the examples shown in Figures 3 and 4, the first part ST11 includes a tip ST11A, a base ST11B, a holding portion ST11C, a first mounting portion ST11D, and a second mounting portion ST11E. The tip ST11A is the part that grasps microvessels BL, etc. The base ST11B is the part that is joined to the second part ST12 of the forceps ST1 by, for example, welding. In other words, in the examples shown in Figures 3 and 4, the forceps ST1 are a so-called "joint-type" forceps, which are constructed by joining two members together by welding or the like. In other examples, the forceps ST1 may be a so-called "folded" type of forceps, which is constructed by bending a single component.

[0020] In the examples shown in Figures 3 and 4, the held portion ST11C is the part between the tip portion ST11A and the base portion ST11B, and is the part held by the surgeon. More specifically, the held portion ST11C is the part that comes into contact with the surgeon's non-dominant thumb. The first mounting portion ST11D is the part to which the tip-side member 13A of the connecting member 13, which will be described later, is attached. The second mounting portion ST11E is the part to which the base-side member 13B of the connecting member 13, which will be described later, is attached. The second part ST12 includes a tip ST12A, a base ST12B, and a holding part ST12C. The tip ST12A is the part that works in cooperation with the tip ST11A of the first part ST11 to grasp microvessels BL, etc. The base ST12B is the part that is joined to the base ST11B of the first part ST11 by, for example, welding. The holding part ST12C is the part between the tip ST12A and the base ST12B, and is the part that is held by the operator. In detail, the holding part ST12C is the part that comes into contact with the index finger of the operator's non-dominant hand.

[0021] Furthermore, in the examples shown in Figures 3 and 4, the connecting member 13 includes a tip-side member 13A and a base-side member 13B. The tip-side member 13A is the member positioned on the tip side of the forceps ST1 (right side in Figures 3 and 4) of the tip-side member 13A and the base-side member 13B. The base-side member 13B is the member positioned on the base side of the forceps ST1 (left side in Figures 3 and 4) than the tip-side member 13A. The tip-side member 13A includes a housing-side connection portion 13A1 and a surgical instrument-side connection portion 13A2. The surgical instrument side connection portion 13A2 is the portion that is attached to the first mounting portion ST11D of the first portion ST11 of the forceps ST1. As shown in Figures 3 and 4, the surgical instrument side connection portion 13A2 is formed by bending a part of the plate-shaped member that constitutes the tip-side member 13A. In the example shown in Figures 3 and 4, the surgical instrument side connection portion 13A2 is crimped to the first mounting portion ST11D of the first portion ST11 of the forceps ST1, thereby connecting the surgical instrument side connection portion 13A2 of the tip-side member 13A to the first portion ST11 of the forceps ST1. In other examples, the surgical instrument-side connection portion 13A2 of the tip-side member 13A may have a different shape from the examples shown in Figures 3 and 4, and the tip-side member 13A and the forceps ST1 may be connected by a different method (e.g., bonding, welding, press-fitting, etc.) than the examples shown in Figures 3 and 4.

[0022] In the examples shown in Figures 3 and 4, the housing-side connection portion 13A1 is the part that connects to the housing portion 12C of the auxiliary imaging device 12. As shown in Figures 3, 4, and 5, the housing-side connection portion 13A1 is roughly U-shaped and has a complementary shape to the roughly cylindrical outer surface of the housing portion 12C of the auxiliary imaging device 12. In the examples shown in Figures 3, 4, and 5, the housing portion 12C of the auxiliary imaging device 12 and the tip-side member 13A are connected by press-fitting the housing portion 12C of the auxiliary imaging device 12 into the housing portion-side connection portion 13A1 of the tip-side member 13A. In other examples, the housing-side connection portion 13A1 of the tip-side member 13A may have a different shape from the examples shown in Figures 3, 4, and 5, and the tip-side member 13A and the housing portion 12C of the auxiliary imaging device 12 may be connected by a different method (e.g., bonding, welding, crimping, etc.) than the examples shown in Figures 3, 4, and 5.

[0023] In the examples shown in Figures 3 and 4, the root-side member 13B includes a housing-side connection portion 13B1 and a surgical instrument-side connection portion 13B2. The surgical instrument side connection portion 13B2 is the portion that is attached to the second mounting portion ST11E of the first portion ST11 of the forceps ST1. As shown in Figures 3 and 4, the surgical instrument side connection portion 13B2 is formed by bending a part of the plate-shaped member that constitutes the base side member 13B. In the examples shown in Figures 3 and 4, the surgical instrument side connection portion 13B2 is crimped to the second mounting portion ST11E of the first portion ST11 of the forceps ST1, thereby connecting the surgical instrument side connection portion 13B2 of the base member 13B to the first portion ST11 of the forceps ST1. In other examples, the surgical instrument-side connection portion 13B2 of the root-side member 13B may have a different shape from the examples shown in Figures 3 and 4, and the root-side member 13B and the forceps ST1 may be connected by a different method (e.g., bonding, welding, press-fitting, etc.) than the examples shown in Figures 3 and 4.

[0024] In the examples shown in Figures 3 and 4, the housing-side connection portion 13B1 is the part that connects to the housing portion 12C of the auxiliary imaging device 12. As shown in Figures 3, 4, and 5, the housing-side connection portion 13A1 is roughly U-shaped. In the examples shown in Figures 3, 4, and 5, as described above, the housing portion 12C of the auxiliary imaging device 12 is pressed into the housing portion side connection portion 13A1 of the tip-side member 13A, thereby causing the housing portion 12C of the auxiliary imaging device 12 to abut against (i.e., connect to) the housing portion side connection portion 13B1 of the base-side member 13B. In other examples, the housing-side connection portion 13B1 of the root-side member 13B may have a different shape from the examples shown in Figures 3, 4, and 5. Unlike the examples shown in Figures 3, 4, and 5, where the housing portion 12C of the auxiliary imaging device 12 abuts against the housing-side connection portion 13B1 of the root-side member 13B, the housing portion 12C of the auxiliary imaging device 12 and the housing-side connection portion 13B1 of the root-side member 13B may be joined (fixed) by means of adhesive, welding, press-fitting, crimping, etc.

[0025] Figures 6 to 8 show the housing portion 12C of the auxiliary imaging device 12, the connecting member 13, and the forceps ST1, all connected together, and simulate how the forceps ST1 of the forceps ST1 are held by the operator and used for microvascular anastomosis in microsurgery. In the examples shown in Figures 6 to 8, the auxiliary imaging device 12 is connected to the forceps ST1, which are surgical instruments ST held by the surgeon, and images the surgical field at a different angle from the main body of the surgical microscope 11.

[0026] Figure 9 shows a comparison of an example of an image of the surgical field captured by the surgical microscope body 11 and an example of an image of the surgical field captured by the auxiliary imaging device 12. Specifically, Figure 9(A) shows an example of an image of the surgical field captured by the surgical microscope body 11, and Figure 9(B) shows an example of an image of the surgical field captured by the auxiliary imaging device 12. As shown in Figure 9(A), the central axis of the two microvessels BL anastomosed in microsurgery extends in a direction approximately perpendicular to the optical axis of the objective lens 11A1 of the observation optical system 11A of the surgical microscope body 11 (the left-right direction in Figure 9(A)). Therefore, the surgeon cannot obtain a detailed understanding of the inside of the microvessels BL anastomosed in microsurgery by using only the image of the surgical field captured by the surgical microscope body 11 shown in Figure 9(A). As shown in Figure 9(B), the central axes of the two microvessels BLs anastomosed in microsurgery form a small acute angle (for example, an acute angle less than 30°) with the optical axis of the imaging unit 12A of the auxiliary imaging device 12. Therefore, as shown in Figure 9(B), the surgeon can use the image of the surgical field captured by the auxiliary imaging device 12 (i.e., the image of the surgical field shown in Figure 9(B)) with the end of the microvessel BL facing the imaging unit 12A of the auxiliary imaging device 12 (the rightmost microvessel BL in Figure 9(A) of the two microvessel BLs shown in Figure 9(A)) spread open with the first part ST11 and the second part ST12 of the forceps ST1 to gain a detailed understanding of the inside of the microvessel BL facing the imaging unit 12A of the auxiliary imaging device 12 (the microvessel BL shown in Figure 9(B)).

[0027] Figure 10 is a diagram illustrating the information about microvascular BLs (branch nodes) that the surgeon needs when performing microvascular anastomosis in microsurgery. Specifically, Figure 10(A) shows a cross-section of a microvascular BL where the intima has not been dissected, and Figure 10(B) shows a cross-section of a microvascular BL where the intima has been dissected. As shown in Figure 10(B), if the intima of the end of the microvessel BL to be anastomosed in microsurgery (i.e., the portion of the microvessel BL sutured with suture SR) is detached, the surgeon needs to take measures after microvascular anastomosis to prevent thrombus formation in the microvessel BL due to the detached intima (specifically, by pressing the detached intima against the inner wall of the microvessel BL with suture SR). In order to determine whether or not such measures are necessary, the surgeon needs information on whether or not the intima of the end of the microvessel BL to be anastomosed in microsurgery is detached. However, as described above, the central axis of the two microvessels BL that are anastomosed in microsurgery extends in a direction approximately perpendicular to the optical axis of the objective lens 11A1 of the observation optical system 11A of the surgical microscope body 11 (left-right direction in Figure 9(A)). Therefore, by using only the image of the surgical field captured by the surgical microscope body 11 shown in Figure 9(A), the surgeon is unable to grasp the interior of the ends of the microvessels BL that are anastomosed in microsurgery in detail, and it is difficult to obtain information on whether or not the intima at the ends of the microvessels BL has been dissected.

[0028] Therefore, in the surgical microscope system 1 of the first embodiment, as shown in Figure 9(B), the imaging unit 12A of the auxiliary imaging device 12 images the surgical field in which the intima inside the end of the microvessel BL to be anastomosed in microsurgery can be confirmed. Thus, according to the surgical microscope system 1 of the first embodiment, the surgeon can be provided with an image of the surgical field shown in Figure 9(B), which allows confirmation of the intima inside the end of the microvessel BL to be anastomosed in microsurgery, as seen from the position of the forceps ST1.

[0029] Furthermore, in the surgical microscope system 1 of the first embodiment, as shown in Figures 6 to 8, the surgical instrument side connection portion 13A2 of the tip-side member 13A and the surgical instrument side connection portion 13B2 of the base-side member 13B are connected to the first portion ST11 of the forceps ST1, which is the portion that comes into contact with the thumb of the surgeon's non-dominant hand. In other words, the imaging unit 12A of the auxiliary imaging device 12 is connected to the first portion ST11 of the forceps ST1, which is the portion that comes into contact with the thumb of the surgeon's non-dominant hand, via the connecting member 13. Therefore, according to the surgical microscope system 1 of the first embodiment, when the surgeon moves the tip ST12A of the second part ST12 of the forceps ST1 by moving the index finger toward the thumb, shaking of the image of the surgical field captured by the imaging unit 12A can be suppressed.

[0030] Figure 11 is a sequence diagram illustrating an example of a process performed in the surgical microscope system 1 of the first embodiment. In the example shown in Figure 11, in step S11, the observation optical system 11A of the surgical microscope body 11 images the surgical field as shown in Figure 9(A). Next, in step S12, the display device 11B of the surgical microscope body 11 displays the image of the surgical field captured in step S11.

[0031] In the example shown in Figure 11, steps S13 to S15 are executed in parallel with steps S11 and S12. In detail, in step S13, with the auxiliary imaging device 12 connected to the forceps ST1 held by the surgeon, the imaging unit 12A of the auxiliary imaging device 12 images the surgical field as shown in Figure 9(B). In other words, the imaging unit 12A of the auxiliary imaging device 12 images the surgical field at an angle different from the angle shown in Figure 9(A). Next, in step S14, the interface unit 12D of the auxiliary imaging device 12 transmits the surgical field image data acquired in step S13 to the auxiliary display device 14. Next, in step S15, the auxiliary display device 14 displays the image of the surgical field acquired in step S13. The surgeon uses the surgical field image displayed in step S12 and the surgical field image displayed in step S15 to perform microvascular anastomosis in microsurgery.

[0032] As described above, in the surgical microscope system 1 of the first embodiment, the auxiliary imaging device 12 is connected to the forceps ST1 held by the surgeon and images the surgical field at a different angle from the surgical microscope body 11. Therefore, the surgical microscope system 1 of the first embodiment can provide the surgeon with an image of the surgical field from the position of the forceps ST1 held by the surgeon during microsurgery.

[0033] [Second Embodiment] The following describes a second embodiment of the surgical microscope system, auxiliary imaging device, and surgical field imaging method of the present invention. The surgical microscope system 1 of the second embodiment is configured in the same way as the surgical microscope system 1 of the first embodiment described above, except for the points described later. Therefore, the surgical microscope system 1 of the second embodiment can achieve the same effects as the surgical microscope system 1 of the first embodiment described above, except for the points described later.

[0034] Figure 12 shows an example of a surgical microscope system 1 according to a second embodiment. In the example shown in Figure 12, the surgical microscope system 1 of the second embodiment is used, similar to the surgical microscope system 1 of the first embodiment, for example, when microvascular anastomosis is performed in microsurgery.

[0035] In the example shown in Figure 12, the surgical microscope system 1 of the second embodiment comprises a surgical microscope body 11, an auxiliary imaging device 12, a connecting member 13, and an auxiliary display device 14. The surgical microscope body 11 of the second embodiment is configured similarly to the surgical microscope described on the website shown at the URL below. https: / / topconhealthcare.jp / ja / wp-content / uploads / sites / 25 / 2020 / 08 / OMS-90_Brochure_E343_Rev1.pdf https: / / www.medicalexpo.com / ja / prod / dre-medical / product-76042-733911.html

[0043] In an example of the surgical microscope system 1 of the third embodiment, the surgeon can view the surgical field through the eyepiece 11A3, and can also view the surgical site (two nerves, lymphatic vessels, etc., to be anastomosed in microsurgery) from a different angle than the surgical microscope body 11 by using the auxiliary display device 14.

[0044] In the surgical microscope system 1 of the third embodiment, similar to the surgical microscope system 1 of the first embodiment, the surgical instrument side connection portion 13A2 of the tip-side member 13A and the surgical instrument side connection portion 13B2 of the base-side member 13B are connected to the first portion ST11 of the forceps ST1, which is the part that comes into contact with the thumb of the surgeon's non-dominant hand. In other words, the imaging unit 12A of the auxiliary imaging device 12 is connected to the first portion ST11 of the forceps ST1, which is the part that comes into contact with the thumb of the surgeon's non-dominant hand, via the connecting member 13. Therefore, according to the surgical microscope system 1 of the third embodiment, similar to the surgical microscope system 1 of the first embodiment, when the surgeon moves the tip ST12A of the second part ST12 of the forceps ST1 by moving the index finger toward the thumb, the shaking of the image of the surgical field captured by the imaging unit 12A can be suppressed.

[0048] In an example of the surgical microscope system 1 of the fourth embodiment, the imaging unit 12A images the surgical area included in the surgical field imaged by the surgical microscope body 11 at an angle different from that of the surgical microscope body 11. Therefore, the surgeon can confirm the surgical field through the eyepiece 11B2, and can also confirm the surgical area at an angle different from that of the surgical microscope body 11 by using the auxiliary display device 14.

[0049] In an example of the surgical microscope system 1 of the fourth embodiment, the connecting member 13 connects a surgical instrument ST (the surgical instrument ST may be a surgical instrument ST other than the forceps ST1) held by the surgeon to an auxiliary imaging device 12.

[0050] In the surgical microscope system 1 of the fourth embodiment, the auxiliary imaging device 12 is connected to the surgical instrument ST held by the surgeon and images the surgical field at a different angle from the surgical microscope body 11.
