Description

[Technical Field]

[0001] The present disclosure relates to medical drapes and medical drape units. [Background technology]

[0002] A well-known example of an X-ray fluoroscopy device is one equipped with a C-arm, which is a C-shaped arm. Generally, surgical medical equipment is covered with a sterilized surgical drape or the like to prevent contamination of the surgical field.

[0003] For example, Patent Document 1 discloses a drape for covering the C-arm of an X-ray fluoroscopy device. The drape disclosed in Patent Document 1 includes multiple adhesive strips, which are sequentially attached to the arm portion to tightly cover the arm portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2013-502286 Summary of the Invention [Problem to be solved by the invention]

[0005] The arm of an X-ray fluoroscopy device is often configured to be freely rotatable so that the affected area of ​​a patient can be photographed with X-rays from various angles. Therefore, during X-ray fluoroscopy, a certain part of the arm may be moved from a clean field to an unclean field, and after photographing the affected area, it may be returned to the clean field.

[0006] In this case, even if the arm is covered with a drape as in the conventional technology described above, the drape itself becomes contaminated in the unclean field, and the contaminated drape is returned to the clean field. This can lead to contamination of the surgical field due to the contaminated drape, which can lead to postoperative infections. Furthermore, if the arm drape needs to be replaced during surgery to avoid postoperative infections, various costs will be incurred, including not only the cost of the drape but also the time and personnel costs involved in the surgery.

[0007] The present disclosure has been made in consideration of the above circumstances, and aims to provide a medical drape and a medical drape unit that can reduce the risk of surgical field contamination while suppressing various costs. [Means for solving the problem]

[0008] One embodiment of the medical drape disclosed herein is a medical drape used on a C-arm X-ray imaging device that is used next to an operating table and has an arm that is rotatably attached to a support base, and includes a drape body that covers the arm with a gap to allow the arm to move, an attachment part that attaches the drape body to the top of the arm, and an engaging part that engages with the operating table or the support base and prevents the drape from moving below the operating table when the arm moves downward. [Effects of the Invention]

[0009] According to the present disclosure, it is possible to provide a medical drape and a medical drape unit that can reduce the risk of contamination of the surgical field while suppressing various costs. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present disclosure (hereinafter simply referred to as "the present embodiment") will be described in detail with reference to the drawings.

[0012] First, before describing the medical drape of this embodiment, an X-ray fluoroscopic imaging device whose arms are covered with the medical drape of this embodiment will be described.

[0013] In this embodiment, an orthopedic X-ray fluoroscopy device having a C-arm, which is a C-shaped arm, will be described as an example. X-ray fluoroscopy devices having a C-arm are frequently used in orthopedic surgery, such as trauma, joint, and spinal surgery. However, the X-ray fluoroscopy device to which the medical drape of this embodiment can be applied is not limited to this. As will be described in detail later, the medical drape of this embodiment can be applied to any X-ray fluoroscopy device that at least supports a rotatable arm, and the medical drape of this embodiment can also be applied to X-ray fluoroscopy devices used for purposes other than orthopedic surgery.

[0014] FIG. 1 is a side view showing an example of the external configuration of an X-ray fluoroscopy apparatus 10 in an AP view (Anterior-Posterior View) of this embodiment. The AP view means that the X-ray irradiation direction is from the front (Anterior) to the back (Posterior) of the patient. FIG. 2 is a side view showing an example of the external configuration of an X-ray fluoroscopy apparatus 10 in a lateral view of this embodiment. The lateral view means that the X-ray irradiation direction is from the side of the patient.

[0015] 1 and 2, the X-ray fluoroscopy apparatus 10 includes an X-ray source 11, an X-ray detector 12, an arm 13, an arm support unit 14 (an example of a support unit), a main body unit 15, and a dolly 16. In the following, as shown in each drawing including Fig. 1 and Fig. 2, the X-ray fluoroscopy apparatus 10 will be described with the front-to-rear direction of the X-ray fluoroscopy apparatus 10 as the x-axis, the left-to-right direction of the X-ray fluoroscopy apparatus 10 as the y-axis, and the vertical direction of the X-ray fluoroscopy apparatus 10 as the z-axis.

[0016] The X-ray fluoroscopy apparatus 10 is an apparatus that uses X-rays to fluoroscopically view the affected area of ​​a patient P lying supine on an operating table O, thereby capturing an X-ray image of the affected area. The X-ray images captured by the X-ray fluoroscopy apparatus 10 may be either still images or moving images. The X-ray fluoroscopy apparatus 10 is a mobile apparatus equipped with a dolly 16, and therefore can be individually moved to a different location and its orientation can be changed.

[0017] The X-ray source 11 is provided at one end of the arm 13. The X-ray source 11 generates X-rays and irradiates the generated X-rays toward the affected area of ​​the patient P. In detail, the X-ray source 11 includes a radiation tube and a collimator (both not shown). The radiation tube generates X-rays by causing electrons generated from a cathode to collide with an anode. The collimator narrows the irradiation field of the X-rays generated by the radiation tube. In this way, the X-rays generated by the radiation tube are irradiated toward the affected area of ​​the patient P.

[0018] The X-ray detector 12 is provided at the other end of the arm 13. In other words, the X-ray detector 12 is provided at the end opposite to the end of the arm 13 where the X-ray source 11 is provided. This positions the X-ray detector 12 and the X-ray source 11 facing each other.

[0019] The X-ray detector 12 detects X-rays emitted from the X-ray source 11 and transmitted through the affected area of ​​the patient P, and generates an X-ray image of the affected area. Specifically, the X-ray detector 12 converts the incident X-rays into electrical signals, and generates an X-ray image of the affected area of ​​the patient P based on the converted electrical signals. The X-ray detector 12 may be either a direct conversion type that directly converts radiation into electrical signals, or an indirect conversion type that converts radiation into visible light using a scintillator and then converts the converted visible light into electrical signals. The X-ray detector 12 may be, for example, a digital radiography (DR) type flat panel detector (FPD), but is not limited to this.

[0020] The arm 13 is a C-arm that has a C-shape when the X-ray fluoroscopy apparatus 10 is viewed from the side. In the example shown in FIG. 1 , the arm 13 has a C-shape when the X-ray fluoroscopy apparatus 10 is viewed from the side in the -y direction, that is, from the back side to the front side. The shape of the arm 13 is not limited to this, but when applying the medical drape of this embodiment, it is preferable that at least a portion of the arm 13 has an arc shape so that it can rotate orbitally. The orbital rotation is a rotation about a virtual axis extending in the y direction, with the outer shape of the arc-shaped arm 13 as the orbit.

[0021] The arm 13 has two ends. The X-ray source 11 is provided at one end of the arm 13, and the X-ray detector 12 is provided at the other end of the arm 13. As described above, the arm 13 has a C-shape, and is therefore capable of holding the X-ray source 11 and the X-ray detector 12 in an opposing position. In this embodiment, an example will be described in which the X-ray source 11 is provided at the end of the arm 13 that is on the upper side when viewed from the side so that the arm 13 is C-shaped, and the X-ray detector 12 is provided at the end on the opposite side of the arm 13. However, this is not limiting, and the arrangement of the X-ray source 11 and the X-ray detector 12 may be reversed. A gap is secured between the X-ray source 11 and the X-ray detector 12 so that the patient P and the operating table O can be inserted.

[0022] The arm 13 is rotatably supported by the arm support section 14. More specifically, the arm 13 is supported by the arm support section 14 so as to be orbitally rotatable, i.e., rotatable in the circumferential direction of the arm 13 (in the direction of arrow a). For example, when changing the X-ray irradiation direction from the AP view shown in FIG. 1 to the lateral view shown in FIG. 2, the X-ray fluoroscopy apparatus 10 rotates the arm 13 by 90 degrees in the direction of arrow a1 (clockwise). Furthermore, when changing the X-ray irradiation direction back from the lateral view shown in FIG. 2 to the AP view shown in FIG. 1, the X-ray fluoroscopy apparatus 10 rotates the arm 13 by 90 degrees in the direction of arrow a2 (counterclockwise). Note that, hereinafter, rotation of the arm 13 in the direction of arrow a1 (clockwise) may be referred to as forward rotation, and rotation of the arm 13 in the direction of arrow a2 (counterclockwise) may be referred to as reverse rotation.

[0023] The arm support portion 14 rotatably supports the arm 13. The arm support portion 14 includes a guide portion 14A and a connection portion 14B. The guide portion 14A supports the arm 13 so that it can rotate in the circumferential direction of the arm 13 (the direction of arrow A), and guides the rotation of the arm 13 in the circumferential direction. The connection portion 14B connects the arm support portion 14 to the main body portion 15. Although detailed explanation will be omitted, the connection portion 14B can be raised and lowered in the z-axis direction relative to the main body portion 15. Therefore, the connection portion 14B (arm support portion 14) can raise and lower the arm 13 to match the height of the operating table O.

[0024] The main body 15 houses various control boards, a power supply, and the like for realizing various functions of the X-ray fluoroscopic imaging apparatus 10. The main body 15 is mounted on a cart 16.

[0025] The cart 16 has a plurality of casters, such as casters 16A and 16B, and is capable of running on the floor. At least some of the casters 16A and 16B serve as swiveling steering wheels. The cart 16 has steering wheels, so it can easily change its direction of travel.

[0026] Although detailed explanation is omitted, the X-ray fluoroscopy device 10 also includes a switch for irradiating X-rays, and an operation panel for giving instructions to rotate the arm 13 and displaying X-ray images (all of which are not shown).

[0027] Next, we will explain an arm drape, which is a conventional medical drape used to cover the C-arm of an X-ray fluoroscopy device, and an operating table drape, which is a conventional medical drape used to cover an operating table.

[0028] In the following, a conventional X-ray fluoroscopy apparatus in which a C-arm is covered with an arm drape will be described as having the same functions and structure as the X-ray fluoroscopy apparatus 10 of this embodiment. However, in order to distinguish between this disclosure and the conventional technology, the X-ray fluoroscopy apparatus used in the description of the conventional technology will be assigned a different reference numeral from the X-ray fluoroscopy apparatus 10 of this embodiment.

[0029] 3 is a side view showing an example of the external configuration of an X-ray fluoroscopy apparatus 90 in which an arm 93 is covered with a conventional arm drape 910, and an operating table O in which an operating table drape 990 is covered with a conventional operating table drape 990. Note that FIG. 3 shows the X-ray fluoroscopy apparatus 90 in an AP view.

[0030] 3, the X-ray fluoroscopy apparatus 90 includes an X-ray source 91, an X-ray detector 92, an arm 93, an arm support 94, a main body 95, and a dolly 96. The arm support 94 includes a guide portion 94A and a connection portion 94B. The dolly 96 has a plurality of casters such as casters 96A and 96B.

[0031] As described above, the X-ray fluoroscopy apparatus 90 has the same functions and structure as the X-ray fluoroscopy apparatus 10. Therefore, the X-ray source 91, the X-ray detector 92, the arm 93, the arm support 94, the guide 94A, the connection 94B, the main body 95, the carriage 96, and the casters 96A and 96B have the same functions and structures as the X-ray source 11, the X-ray detector 12, the arm 13, the arm support 14, the guide 14A, the connection 14B, the main body 15, the carriage 16, and the casters 16A and 16B, respectively. Therefore, a description of each of these components will be omitted. The directions of arrow k, arrow k1, and arrow k2 shown in FIG. 3 correspond to the directions of arrow a, arrow a1, and arrow a2 shown in FIGS. 1 and 2, respectively.

[0032] The arm drape 910 is a conventional medical drape that tightly covers the arm 93. Specifically, the arm drape 910 is a sterilized C-arm cover that tightly covers the C-arm 93. The arm drape 910 can be made of polyethylene film or the like. In the example shown in FIG. 3, the arm drape 910 is represented by diagonal hatching.

[0033] Covering in a tight contact state means that the arm 93 and the arm drape 910 are covered to such an extent that they can rotate in sync when the arm 93 is rotated in the direction of arrow k. Therefore, it is not necessary for the arm drape 910 to be fixed to the arm 93. For example, if the arm drape 910 covers the arm 93 by a distance that allows the arm 93 and the arm drape 910 to move in sync due to frictional force generated when the arm 93 rotates, it can be said that the arm drape 910 covers the arm 93 in a tight contact state even if the arm drape 910 is not fixed to the arm 93.

[0034] Examples of methods for tightly covering the arm 93 with the arm drape 910 include a method of attaching the arm drape 910 to the arm 93 with an adhesive strip, as disclosed in the above-mentioned Patent Document 1. Another example is a method of covering the arm 93 with an arm drape 910 of a size that matches the cross-sectional width of the arm 93. Note that covering the arm 93 with the arm drape 910 can be done by removing the arm 93 from the arm support part 94, as necessary.

[0035] 3, the arm drape 910 integrally covers the X-ray source 91 and the X-ray detector 92 in addition to the arm 93, but it may also be capable of covering only the arm 93. In the latter case, in addition to the arm drape 910, an image cover or the like that covers the X-ray source 91 and the X-ray detector 92 may be separately prepared.

[0036] The operating table drape 990 is a conventional medical drape that covers the operating table O. The operating table drape 990 can be formed from a polyethylene film or the like. In the example shown in FIG. 3, the hanging portion 990A of the operating table drape 990 on the side closer to the main body 95 (the -x direction side) is long enough not to obstruct the arm 93 from entering the lower part of the operating table O. On the other hand, the hanging portion 990B of the operating table drape 990 on the side farther from the main body 95 (the +x direction side) is long enough to sufficiently cover the arm 93 and the X-ray detector 92 to prevent the arm 93 from contaminating the clean field after passing under the operating table O. The clean field is an area in an operating room where cleanliness must be ensured, and is generally defined as the area (space) above the lower part of the operating table, but is not limited thereto. As shown in FIG. 3, the hanging portion 990B is longer than the hanging portion 990A.

[0037] Next, we will explain the problems with conventional arm drapes and conventional operating table drapes, specifically the risk of contamination of the surgical field that can occur when using each of the conventional medical drapes.

[0038] Fig. 4 is a diagram showing the contaminated state in an AP view of a conventional arm drape 910 and an operating table drape 990. Fig. 4 also shows an example of the external configuration of an X-ray fluoroscopic imaging device 90 in which an arm 93 is covered with a conventional arm drape 910, and an operating table O in which an operating table drape 990 is covered with a conventional operating table drape 990, from the side.

[0039] As mentioned above, in a typical operating room, the area above the bottom of the operating table is considered to be an area where cleanliness must be guaranteed (clean field), and the area below this is considered to be an area where cleanliness does not have to be guaranteed (unclean field). In the following description of this embodiment, the area that forms the boundary between the clean field and the unclean field will be referred to as the boundary area.

[0040] In the example shown in Fig. 4, the area below boundary area BA (in the -z direction) is an unclean area. Therefore, the portion of arm drape 910 located below boundary area BA is shown as contaminated area APP1 of arm drape 910. In the example shown in Fig. 4, contaminated area APP1 is represented by hatching with narrower diagonal lines than arm drape 910. Note that in reality, the drape portion covering the X-ray detector 92 is also contaminated, but since it is normally unlikely that this portion would be moved to the clean area in that state (without any countermeasures), its description is omitted here.

[0041] Furthermore, the portion of the hanging portion 990B of the operating table drape 990 that is located below the boundary area BA (in the -z direction) is also shown as the contaminated portion OPP1 of the operating table drape 990. In the example shown in Figure 4, the contaminated portion OPP1 is indicated by diagonal hatching. In reality, the portion of the hanging portion 990A of the operating table drape 990 that is located below the boundary area BA is also contaminated, but because this portion would not normally move into the sterile field, its description is omitted here.

[0042] Fig. 5 is a diagram showing the contaminated state of an arm drape 910 and an operating table drape 990 of the prior art after changing from the AP view shown in Fig. 4 to a lateral view. To be more specific, the lateral view shown in Fig. 5 is a state in which the arm 93 has been rotated 90 degrees in the direction of arrow k1 from the AP view shown in Fig. 4. Fig. 5 also shows a side view of an example of the external configuration of an X-ray fluoroscope 90 in which the arm 93 is covered with a prior art arm drape 910, and an operating table O covered with a prior art operating table drape 990.

[0043] In the example shown in Fig. 5, in addition to the contaminated portion APP1 shown in Fig. 4, a portion of the arm drape 910 located below (in the -z direction) the boundary area BA in the LATERAL view shown in Fig. 5 is shown as a contaminated portion APP2 of the arm drape 910. The contaminated portion APP2 is represented by the same hatching as the contaminated portion APP1 shown in Fig. 4. As shown in Fig. 5, the contaminated portion APP2 of the arm drape 910 extends to almost the entire area of ​​the arm drape 910 except for the portion below the X-ray source 91.

[0044] In the example shown in Figure 5, the arm 93 passes under the operating table O, and on the opposite side of the main body 95 and the operating table O, the X-ray detector 92 is positioned above (in the +z direction) the boundary area BA with the hanging portion 990B of the operating table drape 990 lifted up.

[0045] Here, the contaminated drape portion covering the X-ray detector 92 and part of the contaminated portion APP2 of the arm drape 910 are located in the clean field above the boundary area BA, but are covered by the hanging portion 990B of the operating table drape 990, so they are unlikely to pose a risk of contaminating the surgical field. However, the contaminated portion OPP1 of the hanging portion 990B of the operating table drape 990 is located in the clean field above the boundary area BA, so there is a high possibility that this will pose a risk of contaminating the surgical field.

[0046] For example, if an operator such as an orthopedic surgeon (operator) or an assistant touches the contaminated portion OPP1 to support the X-ray detector 92 in lifting the hanging portion 990B of the operating table drape 990, the operator's hands will also become contaminated, posing a risk of contamination of the surgical field. Furthermore, if the X-ray detector 92 lifts the hanging portion 990B of the operating table drape 990 and the contaminated portion OPP1 is positioned in the clean area, and the contaminated portion OPP1 comes into contact with the operator's surgical clothes, the operator's surgical clothes will also become contaminated, posing a risk of contamination of the surgical field.

[0047] As described above, with the conventional operating table drape 990, when changing from the AP view to the lateral view, the contaminated portion OPP1 moves into the clean field, which can lead to contamination of the surgical field, which is a problem.

[0048] Fig. 6 is a diagram showing the contaminated state of the arm drape 910 and the operating table drape 990 of the prior art after returning to the AP view from the lateral view shown in Fig. 5. Supplementally, the AP view shown in Fig. 6 is a state in which the arm 93 has been rotated 90 degrees in the direction of arrow k2 from the lateral view shown in Fig. 5. Fig. 6 also shows a side view of an example of the external configuration of an X-ray fluoroscope 90 in which the arm 93 is covered with the arm drape 910 of the prior art, and an operating table O covered with the operating table drape 990 of the prior art.

[0049] 6, there is no newly contaminated portion on the arm drape 910, and the contaminated portion of the arm drape 910 remains as contaminated portion APP2. However, as a result of returning from the lateral view to the AP view, the portion of contaminated portion APP2 that was contaminated in the lateral view has moved into the clean field above the boundary area BA, which increases the risk of contamination of the surgical field.

[0050] 7 is an explanatory diagram showing an example of the principle by which a contaminated portion APP2 of an arm drape 910 in the prior art poses a risk of contamination of the surgical field. Fig. 7 shows a state in which the X-ray fluoroscopy device 90 has been removed from the state shown in Fig. 6, and the orthopedic surgeon S and assistant AS are resuming surgery on a patient P lying supine on an operating table O.

[0051] 6, it is assumed that the contaminated portion APP2 of the arm drape 910 comes into contact with the hanging portion 990A of the operating table drape 990. In this case, as shown in FIG. 7, the portion of the hanging portion 990A of the operating table drape 990 that is located above the boundary area BA becomes the contaminated portion OPP2.

[0052] If the surgery is resumed in this state, there is a high probability that the contaminated portion OPP2 of the hanging portion 990A of the operating table drape 990 will come into contact with the surgical gown of the assistant AS. As a result, the portion of the surgical gown of the assistant AS that comes into contact with the contaminated portion OPP2 will become contaminated as the contaminated portion ASPP, posing a risk of contamination of the surgical field.

[0053] Furthermore, during surgery, the orthopedic surgeon S and the assistant AS may switch positions. In this case, the orthopedic surgeon S's surgical gown may come into contact with the contaminated portion OPP2, thereby contaminating the orthopedic surgeon S's surgical gown and posing a risk of contaminating the surgical field. Furthermore, if the contaminated portion ASPP of the assistant AS who has switched positions comes into contact with the hanging portion 990B of the operating table drape 990, the portion of the hanging portion 990B above the boundary area BA may also become contaminated, posing a risk of contaminating the surgical field.

[0054] As described above, with the arm drape 910 and operating table drape 990 of the prior art, both become contaminated in the unclean field, but may enter the clean field in a contaminated state, creating a risk of contamination of the surgical field.

[0055] The medical drape of this embodiment, which reduces the risk of contamination of the surgical field, will be described below. First, the arm drape of this embodiment will be described.

[0056] Fig. 8 is a front view showing an example of the external configuration of the arm drape 110 of this embodiment. Fig. 9 is a rear view showing an example of the external configuration of the arm drape 110 of this embodiment. Fig. 10 is a side view showing an example of the external configuration of the arm drape 110 of this embodiment.

[0057] The arm drape 110 is a medical drape for covering the arm 13 included in the X-ray fluoroscopy apparatus 10. The arm drape 110 has a drape body 111 and a locking member 114 (an example of a locking portion).

[0058] The drape main body 111 is a main body portion of the arm drape 110 that covers the arm 13. The drape main body 111 is bag-shaped and has an opening at least at the lower end 112. Because the arm drape 110 of this embodiment has such a bag-like shape, the drape main body 111 covers the arm 13 by placing the drape main body 111 over the arm 13 from above. That is, in this embodiment, the arm drape 110 covers the arm 13 by placing the drape main body 111 over the end of the arm 13 on the side where the X-ray source 11 is provided, together with the X-ray source 11. Therefore, the drape main body 111 has a circumferential width that can cover at least not only the arm 13 but also the X-ray source 11.

[0059] Furthermore, the drape body 111 has a notch 113 formed therein that is engaged with the arm support portion 14 when the arm 13 rotates forward and prevents the drape body 111 from following the arm 13. Specifically, the notch 113 is formed at the lower end of the drape body 111 and prevents the upper end of the drape body 111 from following the arm 13. In this embodiment, as shown in FIGS. 8 to 10, the drape body 111 has a semi-elliptical notch 113 at the lower end of its back surface. Note that in this embodiment, as shown in FIGS. 8 to 10, the lower end side of the drape body 111 where the notch 113 is located may be referred to as a lower end portion 111A, and the upper end side of the drape body 111 above the notch 113 may be referred to as an upper end portion 111B.

[0060] The shape of the notch 113 is not limited to the example shown in FIGS. 8 to 10 . As will be described in detail later, the notch 113 is provided in the drape main body 111 so that a portion of the X-ray fluoroscopy apparatus 10 other than the arm 13 can be positioned within the notch 113 when the arm 13 is covered with the arm drape 110. This prevents the upper end 111B of the drape main body 111 from entering the unclean field when the arm 13 rotates in the direction of arrow a1, and allows the upper end 111B to be collected at a portion of the X-ray fluoroscopy apparatus 10 other than the arm 13. Note that, in this embodiment, a case where the portion of the X-ray fluoroscopy apparatus 10 other than the arm 13 is the arm support portion 14 is described as an example, but the present invention is not limited to this. Depending on the structure of the X-ray fluoroscopy apparatus 10, a portion other than the arm support portion 14, such as the main body portion 15, may also be considered.

[0061] Therefore, as long as the above-mentioned object can be achieved, the shape of the notch 113 does not matter. For example, the notch 113 may be rectangular or triangular. The notch 113 may have a planar shape or a three-dimensional shape. As long as the above-mentioned object can be achieved, a slit formed on the lower end side of the drape main body 111 may be used instead of the notch 113. In the following description, the notch 113 will be assumed to be replaceable with a slit.

[0062] The locking member 114 is provided on the drape main body 111 and engages the drape main body 111 with the arm support portion 14, preventing at least a portion of the drape main body 111 from following the arm 13 when the arm 13 rotates in the reverse direction. Specifically, the locking member 114 is provided above the notch 113 and prevents the lower end of the drape main body 111 from following the arm 13. The locking member 114 is provided above the notch 113 on the drape main body 111. The locking member 114 is a member for connecting the drape main body 111 to a portion of the X-ray fluoroscopy apparatus 10 other than the arm 13. As described above, this embodiment will be described taking as an example a case where the portion of the X-ray fluoroscopy apparatus 10 other than the arm 13 is the arm support portion 14, but is not limited to this. In this embodiment, as shown in FIGS. 9 and 10 , the arm drape 110 has an arc-shaped adhesive tape as the locking member 114.

[0063] As will be described in detail later, the locking member 114 is a member that engages with the arm support section 14 and applies tension in the downward direction (-z direction) to prevent the lower end 111A of the drape main body 111 from entering the sterile field when the arm 13 rotates in the direction of arrow a2. Therefore, the type and shape of the locking member 114 are not important as long as the above-mentioned purpose can be achieved. For example, the locking member 114 may be an adhesive member for fixing the drape main body 111 to the arm support section 14. Examples of adhesive members include, but are not limited to, adhesive tape and magnetic tape. Furthermore, the locking member 114 may be an engaging member for engaging the drape main body 111 with the arm support section 14. Examples of engaging members include, but are not limited to, hooks that are hooked onto the arm support section 14. In this embodiment, the locking member 114 is provided above the notch 113 on the drape main body 111, but the position is not important as long as the above-mentioned purpose can be achieved.

[0064] Fig. 11 is a side view showing an example of a state in which the arm 13 included in the X-ray fluoroscopy apparatus 10 of this embodiment is covered with the arm drape 110 of this embodiment. Fig. 12 is a rear view showing an example of a state in which the arm 13 included in the X-ray fluoroscopy apparatus 10 of this embodiment is covered with the arm drape 110 of this embodiment. Note that Figs. 11 and 12 show the X-ray fluoroscopy apparatus 10 in an AP view. Also, while Fig. 11 also shows the operating table O and the patient P, Fig. 12 omits the operating table O and the patient P.

[0065] As described above, the drape main body 111 has an open lower end 112 and a semi-elliptical notch 113 at the lower end 111A. Therefore, the arm drape 110 covers the arm 13 by placing the drape main body 111 over one end of the arm 13 that is on the upper side when the X-ray fluoroscopy apparatus 10 is viewed from the side. Specifically, as shown in FIGS. 11 and 12 , the arm drape 110 covers the arm 13 by placing the drape main body 111 over the X-ray source 11 and the end of the arm 13 on the side where the X-ray source 11 is provided.

[0066] 11 and 12, the arm drape 110 is positioned so that the notch 113 of the drape body 111 is positioned on the arm support section 14. Specifically, as shown in Fig. 11 and Fig. 12, by positioning the semi-elliptical notch 113 of the drape body 111 on the arm support section 14, the drape body 111 is configured to straddle the arm support section 14. As a result, on the upper end section 111B side of the drape body 111, the drape body 111 covers the X-ray source 11 and the arm 13, and on the lower end section 111A side of the drape body 111, the drape body 111 covers the arm 13 in an apron or skirt shape.

[0067] Furthermore, the arm drape 110 has a drape main body 111 connected to the arm support section 14 by a locking member 114. Specifically, as shown in Figures 11 and 12, the locking member 114, which is an adhesive sticker provided above the notch 113, is attached to the connection section 14B of the arm support section 14, thereby fixing the drape main body 111 to the arm support section 14.

[0068] The arm drape 110 of this embodiment covers the arm 13 as described above. If the outer circumferential width of the drape main body 111 is too large compared to the outer circumferential width of the arm 13, the upper end portion 111B of the drape main body 111 may be fixed to the arm 13 with a tape member, string, or the like. However, as will be described in detail later, in this embodiment, the arm 13 needs to be rotatable relative to the drape main body 111. For this reason, when fixing the upper end portion 111B of the drape main body 111 to the arm 13 with a tape member, string, or the like, it is necessary to leave some slack.

[0069] Next, the principle by which the arm drape 110 of this embodiment can reduce the risk of contamination of the surgical field will be described.

[0070] Fig. 13 is a diagram showing the contamination state of the arm drape 110 of this embodiment in an AP view. Fig. 13 shows an example of the external configuration of the X-ray fluoroscopy apparatus 10 in which the arm 13 is covered with the arm drape 110 of this embodiment, from the side. Note that Fig. 13 is primarily intended to explain the principle by which the arm drape 110 can reduce the risk of surgical field contamination, and therefore does not show the operating table drape of this embodiment.

[0071] In the example shown in Fig. 13, the area below the boundary area BA (in the -z direction) is an unclean area. Therefore, the portion of the arm drape 110 that is located below the boundary area BA is shown as the soiled area APP of the arm drape 110. In the example shown in Fig. 13, the soiled area APP is represented by hatching with narrower diagonal lines than the arm drape 110. The soiled area APP is mainly the lower end 111A of the drape main body 111 that covers the arm 13 in an apron or skirt shape.

[0072] Fig. 14 is a diagram showing a contaminated state of the arm drape 110 of this embodiment after changing from the AP view shown in Fig. 13 to the lateral view. Supplementally, the lateral view shown in Fig. 14 is a state in which the arm 13 is rotated 90 degrees in the direction of arrow a1 from the AP view shown in Fig. 13. Fig. 14 also shows an example of the external configuration of the X-ray fluoroscope 10 in which the arm 13 is covered with the arm drape 110 of this embodiment, as viewed from the side.

[0073] In this embodiment, as described above, the arm 13 is rotatable relative to the drape main body 111, and the arm and drape main body do not rotate synchronously from start to finish as in the conventional technology. Therefore, in this embodiment, when one end of the arm 13 is rotated in a direction approaching the arm support section 14, the portion of the drape main body 111 above the notch 113 is crushed and accumulated on the arm support section 14. Specifically, as shown in FIG. 14 , even when the arm 13 rotates in the direction of arrow a1, the upper end section 111B of the drape main body 111 rotates synchronously with the arm 13 only up to the arm support section 14. Then, when the upper end section 111B of the drape main body 111 reaches the arm support section 14 where the notch 113 is located, it is crushed and accumulated on the arm support section 14. In other words, when arm 13 rotates in the direction of arrow a1 (forward direction), notch 113 is locked onto arm support portion 14, so that upper end portion 111B of drape main body 111 does not follow arm 13 but instead remains gathered on arm support portion 14. If arm support portion 14 does not have the shape shown in the figure, a fixing member, locking portion, or the like for preventing following may be provided at an appropriate position on upper end portion 111B of drape main body 111.

[0074] Furthermore, the lower end 111A of the drape body 111, which is mainly the contaminated portion APP, is not fixed to the arm 13 but simply covers the arm 13 in an apron or skirt-like manner, and therefore its position does not change even when the arm 13 rotates in the direction of arrow a1.

[0075] As described above, when the arm drape 110 of this embodiment changes from an AP view to a LATERAL view, the portion located in the sterile field above the boundary area BA (toward the +z direction) is simply crushed and accumulated on the arm support portion 14, but remains in the sterile field.

[0076] Next, a description will be given of the state after the arm 13 is rotated 90 degrees in the direction of arrow a2 from the lateral view shown in Fig. 14 and returns to the AP view. Note that this state corresponds to the AP view state shown in Fig. 13 described above, and therefore the following description will be given with reference to Fig. 13.

[0077] In this embodiment, when one end of the arm 13 is rotated in the reverse direction away from the arm support section 14, the upper portion of the drape main body 111, which has been collapsed and accumulated on the arm support section 14, is returned to a state covering the arm 13 in conjunction with the rotation of the arm 13. Specifically, when the arm 13 is rotated 90 degrees in the direction of arrow a2 from the lateral view shown in Fig. 14, the upper end portion 111B of the drape main body 111 accumulated on the arm support section 14 is pulled by the rotation of the arm 13 and is returned to its original state covering the arm 13 shown in Fig. 13. In other words, when the arm 13 rotates in the direction of arrow a2 (reverse direction), the locking member 114 fixes the top of the notch 113 to the arm support section 14 so that the upper end portion 111B of the drape main body 111 follows the arm 13 and returns to its original state.

[0078] In this embodiment, the locking member 114 is an adhesive tape that is placed on the top of the notch 113 and attached to the arm support portion 14 to prevent a portion of the drape body 111 below the notch 113 from being lifted above the arm support portion 14 when one end of the arm 13 is rotated in the reverse direction away from the arm support portion 14. Specifically, when the arm 13 is rotated 90 degrees in the direction of arrow a2 from the lateral view shown in Fig. 14, the locking member 114 generates a downward (-z direction) tension so that the lower end portion 111A of the drape body 111 remains in a region below (-z direction) the boundary region BA so that the contaminated portion APP of the drape body 111 does not move to the clean field above (+z direction) the boundary region BA due to the pull of the rotation of the arm 13.

[0079] As described above, the arm drape 110 of this embodiment is configured such that when the arm 13 rotates in the forward direction, the notch 113 of the drape main body 111 prevents the drape main body 111 from following the arm 13, whereas when the arm 13 rotates in the reverse direction, the locking member 114 locks the drape main body 111 and prevents the drape main body 111 from following the arm 13. When the arm drape 110 of this embodiment is changed from the lateral view to the AP view, the portion that is collapsed and accumulated on the arm support part 14 simply returns to its original covering state, and the arm drape 110 remains located in the sterile field above the boundary area BA. Note that because the arm drape 110 returns to its original covering state when the view is changed from the lateral view to the AP view, the arm 13 does not move into the sterile field above the boundary area BA without being covered by the arm drape 110. Furthermore, in the arm drape 110 of this embodiment, even when the view changes from LATERAL to AP, the locking member 114 generates downward tension, so that the contaminated portion APP of the drape body 111 does not move to the clean field above (in the +z direction) the boundary area BA.

[0080] (Configuration of the locking part) The locking portion for preventing movement of the arm drape can take various forms. In the above embodiment, a notch that straddles the support base is provided on the underside of the lower part of the arm drape body, and a locking portion is provided to prevent the entire arm drape from moving upward along with the C-arm when the C-arm rises.

[0081] However, the shape of the arm drape is not limited to a "notch" as long as it can lock the arm drape so that it does not move along with the C-arm into the unclean area behind the operating table when the C-arm descends from the home position and moves forward. For example, the arm drape may be configured to have an open bottom end and a hook that engages with the arm support base on the back side of the center of the arm drape, or the center of the arm drape may be temporarily fastened to the arm support base with Velcro (registered trademark). The C-arm may be covered in an area that does not interfere with the C-arm support base, and both ends may be fastened together on the back side of the C-arm with Velcro, hooks, or snaps to form a ring.

[0082] Another possible configuration is to provide a locking portion at the lower end of the arm drape, and then unfold the lower portion of the arm drape to secure it to the operating table. In this case, the lower end of the arm drape can be temporarily secured along the side of the operating table with a clip or Velcro, and then the arm drape can be placed over the upper end of the C-arm and tied together. With this configuration, the arm drape is tied to the top of the C-arm in a fan shape, and the arm drape separates the clean area on the surface of the operating table from the unclean area on the surface of the operating table, completely preventing contaminants and debris from the unclean area behind the operating table from getting onto the top of the operating table along with the arm drape.

[0083] As described above, the arm drape may be configured to be locked to the C-arm support table or the operating table so that it does not move with the C-arm when the C-arm moves forward and rotates toward the operating table surface. Meanwhile, when the C-arm rises and moves in the reverse direction (toward the home position), the upper portion of the arm drape, which remains contracted on the arm support section, moves with the C-arm, while the lower portion does not. To prevent this, the arm drape may be provided with a locking section that locks the top of the arm drape to the upper portion of the C-arm and locks the lower end of the contracted region of the contracted arm drape (the central region of the arm drape) to the arm support section. The central region of the arm drape refers to the boundary region between the clean region on the operating table surface and the unclean region on the operating table surface.

[0084] As described above, with the arm drape of this embodiment, the portion of the drape body located in the clean field does not move into the unclean field, and the portion of the drape body located in the unclean field does not move into the clean field, regardless of whether the view is an AP view or a lateral view. Therefore, with the arm drape of this embodiment, a situation in which a contaminated portion of the drape body enters the clean field does not occur, and the risk of contamination of the surgical field can be reduced.

[0085] Next, a drape for an operating table according to this embodiment will be described as a medical drape according to this embodiment that reduces the risk of contamination of the surgical field.

[0086] FIG. 15 is a side view showing an example of the operating table drape 190 of this embodiment in a state where a pocket region 192 for forming a pocket 195 for accommodating the X-ray detector 12 and a portion of the arm 13 is folded and stored on the operating table O. FIG. 16 is a side view showing an example of the operating table drape 190 of this embodiment in a state where the pocket region 192 is opened to form the pocket 195. Note that FIG. 15 shows an example of the external configuration of the X-ray fluoroscope 10 and the arm drape 110 in an AP view, as well as the operating table O covered with the operating table drape 190 of this embodiment. FIG. 16 shows an example of the external configuration of the X-ray fluoroscope 10 and the arm drape 110 in a lateral view, as well as the operating table O covered with the operating table drape 190 of this embodiment.

[0087] 15 and 16, operating table drape 190 has a covering portion 191, a pocket portion 192, and a fixing portion 193. Covering portion 191, pocket portion 192, and fixing portion 193 are integrally formed on operating table drape 190.

[0088] The covering portion 191 is a portion of the operating table drape 190 that covers the operating table O.

[0089] The pocket region 192 is a region of the operating table drape 190 for forming a pocket 195 that accommodates the X-ray detector 12 and part of the arm 13. The pocket region 192 can form the pocket 195 above the operating table O and can be folded and stored on the operating table O. Specifically, as shown in FIG. 15 , the pocket region 192 is usually folded and stored on the operating table O. In the example shown in FIG. 15 , the pocket region 192 is stored between the patient P and the operating table O.

[0090] Furthermore, when the other end of the arm 13, which is on the lower side when the X-ray fluoroscopy apparatus 10 is viewed from the side, rotates in a direction away from the arm support portion 14, the pocket portion 192 forms a pocket 195 that accommodates the other end of the arm 13 that passes from below to above the side of the operating table O. Specifically, as shown in Fig. 16 , the pocket portion 192 forms the pocket 195 in the sterile field above the boundary area BA (on the +z direction side) that accommodates the X-ray detector 12 and a portion of the arm 13 that pass from below to above the side of the operating table O when the arm 13 rotates in the direction of arrow a1. Note that it is assumed that the formation of the pocket 195 by the pocket portion 192 will be performed manually by an operator such as an assistant, but the present invention is not limited to this.

[0091] The fixed portion 193 is a portion of the operating table drape 190 that is fixed to the floor surface on which the operating table O is placed. For example, as shown in Figures 15 and 16, the fixed portion 193 is fixed to the floor surface by placing a weight 194 on it.

[0092] As described above, when the pocket region 192 is not used, such as during an AP view, the operating table drape 190 of this embodiment is stored on the operating table O located in the clean field above (on the +z side of) the boundary region BA. Furthermore, even when the pocket region 192 is used, such as during a lateral view, the operating table drape 190 of this embodiment can form a pocket in the clean field above (on the +z side of) the boundary region BA.

[0093] As described above, with the operating table drape 190 of this embodiment, the pocket area 192 is always located in the clean field and does not move into the unclean field, regardless of whether the view is an AP view or a lateral view. Therefore, with the operating table drape 190 of this embodiment, the pocket area 192 does not become contaminated in the unclean field, so a situation in which a contaminated portion of the pocket area 192 enters the clean field does not occur, thereby reducing the risk of contaminating the surgical field. Furthermore, with this embodiment, the fixed area 193 is fixed to the floor by the weight 194. Therefore, when the pocket 195 accommodates the X-ray detector 12 and part of the arm 13, the operating table drape 190 bounces up in recoil, preventing a situation in which a contaminated area located in the unclean field below the boundary area BA (in the −z direction) moves into the clean field. This reduces the risk of contaminating the surgical field.

[0094] As described above, with the arm drape 110 and the operating table drape 190 of this embodiment, an incident in which a part contaminated in the unclean field invades the clean field, as in the prior art, does not occur, thereby significantly reducing the risk of contamination of the surgical field and the risk of postoperative infection, etc. Furthermore, with the arm drape 110 and the operating table drape 190 of this embodiment, an incident in which a part contaminated in the unclean field invades the clean field, as in the prior art, does not occur, thereby eliminating the need to change these drapes during surgery and reducing various costs, such as the cost of the drapes, the time cost for the surgery, and the personnel cost.

[0095] (Variation 1) In the above embodiment, the method for fixing upper end portion 111B of drape main body 111 to arm 13 was left to the discretion of an operator such as an orthopedic surgeon or assistant, but an unfamiliar operator, such as a first-time operator, may not know how much slack to leave when fixing upper end portion 111B to arm 13. For this reason, in this modified example, a method will be described that allows even an unfamiliar operator, such as a first-time operator, to easily fix upper end portion 111B to arm 13.

[0096] Fig. 17 is a side view showing an example of a state in which the arm 13 included in the modified X-ray fluoroscopy apparatus 10 is covered with a modified arm drape 210. The example shown in Fig. 17 differs from the above embodiment in that the arm drape 210 further includes adjustment members 220A and 220B for adjusting the circumferential width of the drape main body 111. Note that, because the adjustment members 220A and 220B have the same function and structure, the following description will focus on adjustment member 220A, and a description of adjustment member 220B will be omitted.

[0097] The adjusting member 220A is a member that adjusts the outer circumferential width of the drape body 111 so that the arm 13 can rotate relative to the drape body 111 while the arm 13 is covered by the drape body 111. The adjusting member 220A may be, for example, a tape member arranged in the width direction of the drape body, but is not limited to this. In the modified example, the adjusting members 220A and 220B are arranged in the vertical direction of the drape body 111, but the number of adjusting members arranged on the drape body 111 is not limited to this and may be any number equal to or greater than one. However, it is preferable that the adjusting member be arranged at the upper end portion 111B of the drape body 111.

[0098] FIG. 18 is a cross-sectional view of arm drape 210 at a position where adjustment member 220A of a modified example is arranged. As shown in FIG. 18, adjustment member 220A has adhesive portion 221 at one end, and is fixed to drape main body 111. Adjustment member 220A also has weak adhesive portion 222 with weak adhesive strength and adhesive portion 223 sealed with a backing at the other end. Weak adhesive portion 222 is an adhesive portion for temporarily fastening adjustment member 220A to drape main body 111. Also, adhesive portions 231 to 234 of adhesive portion 223 are indicated on drape main body 111 in the width direction at the position where adjustment member 220A is arranged. Each of adhesive portions 231 to 234 indicates the length to which the circumferential width of drape main body 111 can be adjusted when that adhesive portion is fixed by adhesive portion 223.

[0099] For example, suppose the radius of drape main body 111 is 20 cm, the circumferential width of drape main body 111 is 120 cm, and the length of adjustment member 220A is 60 cm. In this case, adhesive location 231 indicates that the circumferential width of drape main body 111 can be adjusted to 100 cm by adhering adhesive portion 223 at adhesive location 231. Also, adhesive location 232 indicates that the circumferential width of drape main body 111 can be adjusted to 90 cm by adhering adhesive portion 223 at adhesive location 232. Also, adhesive location 233 indicates that the circumferential width of drape main body 111 can be adjusted to 80 cm by adhering adhesive portion 223 at adhesive location 233. Also, adhesive location 234 indicates that the circumferential width of drape main body 111 can be adjusted to 70 cm by adhering adhesive portion 223 at adhesive location 234. Therefore, for example, as shown in FIG. 19, by fixing adhesive portion 223 at adhesive location 233, the outer circumferential width of drape body 111 can be adjusted from 120 cm to 80 cm by adjusting member 220A.

[0100] As described above, according to the modified example, even an unfamiliar operator, such as a first-time operator, can easily adjust the width of the upper end portion 111B of the drape main body 111 to a desired length, and the arm drape 210 can be fixed to the arm 13 to the extent that the arm 13 can fit the arm drape 210. Furthermore, according to the modified example, the width of the upper end portion 111B of the drape main body 111 can be adjusted in multiple stages, making it possible to widely accommodate multiple types of X-ray fluoroscopy devices 10 with different arm widths.

[0101] (Variation 2) In the above embodiment, the case where the locking member 114 is an adhesive tape has been described as an example, but a magnetic tape may also be used. In this case, the magnetic tape may be provided not only on the drape main body 111 side but also on the arm support portion 14 side.

[0102] (Variation 3) In the above embodiment, the drape main body 111 is described as being bag-shaped, but the present invention is not limited to this and may be tubular with both ends open. In this case, the upper end may be tied with a string or the like. Alternatively, for example, the drape main body 111 may not be bag-shaped but may be a single piece of fabric, with both sides of only the upper end portion being connectable with a zipper, tape, button, or the like.

[0103] The above-described embodiment and each modification merely show examples of specific embodiments for carrying out the present disclosure, and the technical scope of the present disclosure should not be interpreted as being limited by these. In other words, the present disclosure can be carried out in various forms without departing from the gist or main features thereof. Furthermore, the above-described embodiment and each modification can be carried out in appropriate combinations. [Explanation of symbols]
