Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, the arm of the X-ray fluoroscopy apparatus is often configured to be rotatable so that the affected part of the patient can be photographed with X-rays from various angles. For this reason, in X-ray fluoroscopy, it is also possible to move a certain part of the arm from the clean area to the unclean area, photograph the affected part, and then return to the clean area again.

[0006] In this case, even if the arm is covered with a drape as in the above-described prior art, the drape itself will be contaminated in the unclean area, and the contaminated drape will return to the clean area. For this reason, there is a risk that the surgical field will be contaminated due to the contaminated drape, leading to postoperative infections and the like. In addition, if the drape of the arm is replaced during the surgery to avoid postoperative infections, various costs such as not only the cost of the drape but also the time cost and labor cost in the surgery will occur.

[0007] The present disclosure has been made in view of the above circumstances, and an object thereof is to provide a medical drape, a medical drape unit, and a method for attaching a medical drape that can suppress the occurrence risk of surgical field contamination while suppressing the occurrence of various costs.

Means for Solving the Problems

[0008] One aspect of the medical drape of the present disclosure is a medical drape for covering an arm rotatably provided on a support portion provided in an X-ray fluoroscopy imaging device, including a drape body covering the arm, a notch formed in the drape body and locked to the support portion when the arm rotates in the forward direction, which prevents the upper part of the drape body from following the arm, and a locking portion provided on the drape body, engaging the drape body with the support portion, and preventing the lower part of the drape body from following the arm when the arm rotates in the reverse direction.

Effects of the Invention

[0009] According to the present disclosure, it is possible to provide a medical drape, a medical drape unit, and a method for attaching a medical drape that can suppress the occurrence risk of surgical field contamination while suppressing the occurrence of various costs.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments 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 the present embodiment, an X-ray fluoroscopy imaging apparatus in which an arm is covered with the medical drape of the present embodiment will be described.

[0013] In this embodiment, an X-ray fluoroscopy imaging apparatus for orthopedic surgery having a C-arm, which is an arm in a C shape, will be described as an example. The X-ray fluoroscopy imaging apparatus having a C-arm is frequently used in orthopedic surgeries such as trauma, joint, and spinal surgeries. However, the X-ray fluoroscopy imaging apparatus to which the medical drape of this embodiment is applied is not limited to this. Although details will be described later, the medical drape of this embodiment is applicable to at least an X-ray fluoroscopy imaging apparatus that rotatably supports an arm, and the medical drape of this embodiment is also applicable to an X-ray fluoroscopy imaging apparatus used for applications other than orthopedics.

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

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

[0016] The X-ray fluoroscopy imaging apparatus 10 is an apparatus that takes an X-ray image of an affected part of a patient P lying supine on an operating table O by fluoroscoping the affected part with X-rays. The X-ray image taken by the X-ray fluoroscopy imaging apparatus 10 may be either a still image or a moving image. Since the X-ray fluoroscopy imaging apparatus 10 is a mobile apparatus having a cart 16, it is possible to individually move the installation location or change the orientation.

[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 part of the patient P. Specifically, the X-ray source 11 includes a radiation tube and a collimator (both not shown). The radiation tube generates X-rays by colliding electrons generated from the cathode with the anode. The collimator narrows the irradiation field of the X-rays generated by the radiation tube. As a result, the X-rays generated by the radiation tube are irradiated toward the affected part of the patient P.

[0018] The X-ray detector 12 is provided at the other end of the arm 13. That is, 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. Thereby, the X-ray detector 12 and the X-ray source 11 are in an opposed positional relationship.

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

[0020] The arm 13 is a C-arm whose shape is C-shaped when the X-ray fluoroscopy imaging device 10 is viewed from the side. In the example shown in FIG. 1, the arm 13 is C-shaped when the X-ray fluoroscopy imaging device 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 in applying the medical drape of the present embodiment, it is preferable that the arm 13 has an arc shape at least partially so that orbital rotation is possible. The orbital rotation is a rotation centered on 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. An X-ray source 11 is provided at one end of the arm 13, and an X-ray detector 12 is provided at the other end of the arm 13. Since the arm 13 has a C shape as described above, the X-ray source 11 and the X-ray detector 12 can be held in a facing posture. In the present embodiment, a case will be described by taking as an example a case where 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 has a C shape, and the X-ray detector 12 is provided at the end on the opposite side of the arm 13. However, it is not limited to this, and the arrangement of the X-ray source 11 and the X-ray detector 12 may be reversed. An interval into which the patient P and the operating table O can be inserted is secured between the X-ray source 11 and the X-ray detector 12.

[0022] The arm 13 is rotatably supported by the arm support portion 14. Specifically, the arm 13 is supported by the arm support portion 14 so as to be rotatable in the circumferential direction of the arm 13, that is, 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 imaging apparatus 10 may rotate the arm 13 90 degrees in the direction of arrow a1 (clockwise). Further, for example, when returning the X-ray irradiation direction from the LATERAL view shown in FIG. 2 to the AP view shown in FIG. 1, the X-ray fluoroscopy imaging apparatus 10 may rotate the arm 13 90 degrees in the direction of arrow a2 (counterclockwise). Hereinafter, the rotation of the arm 13 in the direction of arrow a1 (clockwise) may be referred to as forward rotation, and the 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 as to be rotatable in the circumferential direction of the arm 13 (in 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 and the main body portion 15. Although detailed description is omitted, the connection portion 14B can move up and down in the z-axis direction with respect to the main body portion 15. For this reason, the connection portion 14B (arm support portion 14) can move the arm 13 up and down according to the height of the operating table O.

[0024] The main body portion 15 houses various control boards, power supplies, etc. for realizing various functions of the X-ray fluoroscopic imaging device 10. The main body portion 15 is mounted on a cart 16.

[0025] The cart 16 has a plurality of casters such as casters 16A and 16B and can travel on the floor surface. Also, at least a part of the casters such as casters 16A and 16B are swiveling steering wheels. Since the cart 16 has a steering wheel, the traveling direction can be easily changed.

[0026] Although detailed description is omitted, the X-ray fluoroscopic imaging device 10 also includes a switch for irradiating X-rays, an operation panel for giving a rotation instruction to the arm 13 and displaying an X-ray image, etc. (all are not shown).

[0027] Next, an arm drape which is a medical drape of the prior art used for covering the C-arm of the X-ray fluoroscopic imaging device, and an operating table drape which is a medical drape of the prior art used for covering the operating table will be described.

[0028] Hereinafter, an X-ray fluoroscopic imaging device in which the C-arm is covered with a prior art arm drape will be described as having the same functions and structure as the X-ray fluoroscopic imaging device 10 of the present embodiment. However, in order to distinguish the present disclosure from the prior art, the X-ray fluoroscopic imaging device used in the description of the prior art will be described with a reference numeral different from that of the X-ray fluoroscopic imaging device 10 of the present embodiment.

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

[0030] As shown in Figure 3, the X-ray fluoroscopy apparatus 90 includes an X-ray source 91, an X-ray detector 92, an arm 93, an arm support portion 94, a main body portion 95, and a carriage 96. The arm support portion 94 includes a guide portion 94A and a connection portion 94B. The carriage 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 portion 94, the guide portion 94A, the connection portion 94B, the main body portion 95, the carriage 96, the casters 96A and 96B each have the same functions and structure as the X-ray source 11, the X-ray detector 12, the arm 13, the arm support portion 14, the guide portion 14A, the connection portion 14B, the main body portion 15, the carriage 16, the casters 16A and 16B. For this reason, the description of each of these parts is omitted. Also, the directions of arrow k, arrow k1, and arrow k2 shown in Figure 3 respectively correspond to the directions of arrow a, arrow a1, and arrow a2 shown in Figures 1 and 2.

[0032] The drape 910 for an arm is a prior art medical drape that covers the arm 93 in a close contact state. Specifically, the drape 910 for an arm is a sterilized C-arm cover that covers the arm 93, which is a C-arm, in a close contact state. The drape 910 for an arm can be formed from a polyethylene film or the like. In the example shown in Figure 3, the drape 910 for an arm is represented by diagonal hatching.

[0033] By "covering in a close contact state" is meant that when the arm 93 is rotated in the direction of arrow k, the arm 93 and the arm drape 910 are covered to such an extent that they can rotate synchronously. Therefore, it is not necessarily required that the arm drape 910 be fixed to the arm 93. For example, if the arm drape 910 covers the arm 93 with a sense of distance such that they move synchronously due to the frictional force generated when the arm 93 rotates, it can be said that the arm drape 910 covers the arm 93 in a close contact state even if the arm drape 910 is not fixed to the arm 93.

[0034] As a method of covering the arm 93 with the arm drape 910 in a close contact state, for example, as disclosed in Patent Document 1 mentioned above, there are methods such as attaching the arm drape 910 to the arm 93 with an adhesive strip. Also, for example, there is a method of covering the arm 93 with the arm drape 910 sized according to the cross-sectional width of the arm 93. Note that the covering of the arm 93 with the arm drape 910 may be performed by removing the arm 93 from the arm support portion 94 if necessary.

[0035] In the example shown in FIG. 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 able to cover only the arm 93. In the latter case, in addition to the arm drape 910, an image cover or the like for covering the X-ray source 91 and the X-ray detector 92 may be prepared separately.

[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 portion 95 (-x direction side) has a length that does not inhibit the entry of the arm 93 into 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 portion 95 (+x direction side) has a length that can sufficiently cover the arm 93 and the X-ray detector 92 so as not to contaminate the clean area after the arm 93 passes through the lower part of the operating table O. The clean area is an area where cleanliness must be ensured in the operating room, and generally, it is an area (space) above the lower part of the operating table, but it is not limited to this. As shown in FIG. 3, the hanging portion 990B is longer than the hanging portion 990A.

[0037] Next, the problems of the conventional arm drape and the conventional operating table drape will be described. Specifically, the risk of surgical field contamination that may occur when each conventional medical drape is used will be described.

[0038] FIG. 4 is a diagram showing the contamination state in the AP view of the conventional arm drape 910 and the operating table drape 990. Note that FIG. 4 shows an external configuration example of the X-ray fluoroscopy imaging device 90 covered with the conventional arm drape 910 and the operating table O covered with the conventional operating table drape 990 from the side.

[0039] As described above, in a general operating room, the area above the lower part of the operating table is an area (clean area) where cleanliness must be ensured, and the area below this is an area (dirty area) where cleanliness does not have to be ensured. In the following embodiment, the area that is the boundary between the clean area and the dirty area will be described as the boundary area.

[0040] In the example shown in FIG. 4, the area below the boundary area BA (on the -z direction side) is a contaminated area. Therefore, the portion of the drape 910 for the arm that is located in the area below the boundary area BA is shown as the contaminated portion APP1 of the drape 910 for the arm. In the example shown in FIG. 4, the contaminated portion APP1 is represented by diagonal hatching that is narrower than the drape 910 for the arm. In actuality, the drape portion covering the X-ray detector 92 is also contaminated, but since it is not normal for this portion to move to the clean area as it is (without any countermeasures), the explanation is omitted here.

[0041] Also, the portion of the hanging portion 990B of the drape 990 for the operating table that is located in the area below the boundary area BA (on the -z direction side) is also shown as the contaminated portion OPP1 of the drape 990 for the operating table. In the example shown in FIG. 4, the contaminated portion OPP1 is represented by diagonal hatching. In actuality, the portion of the hanging portion 990A of the drape 990 for the operating table that is located in the area below the boundary area BA is also contaminated, but since it is not normal for this portion to move to the clean area, the explanation is omitted here.

[0042] FIG. 5 is a diagram showing the contamination states of the conventional drape 910 for the arm and the drape 990 for the operating table after changing from the AP view shown in FIG. 4 to the LATERAL view. For supplementation, the LATERAL view shown in FIG. 5 is a state in which the arm 93 is rotated 90 degrees in the direction of arrow k1 from the AP view shown in FIG. 4. Note that FIG. 5 shows an external configuration example of the fluoroscopic imaging apparatus 90 covered with the conventional drape 910 for the arm and the operating table O covered with the conventional drape 990 for the operating table from the side.

[0043] In the example shown in FIG. 5, in addition to the contaminated portion APP1 shown in FIG. 4, in the LATERAL VIEW shown in FIG. 5, the portion of the drape 910 for the arm located below the boundary region BA (on the -z direction side) is shown as the contaminated portion APP2 of the drape 910 for the arm. 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 drape 910 for the arm spreads to almost the entire area excluding the portion below the X-ray source 91 of the drape 910 for the arm.

[0044] Also in the example shown in FIG. 5, the arm 93 passes below the operating table O, and on the opposite side across the main body portion 95 side and the operating table O, the X-ray detector 92 is located above the boundary region BA (on the +z direction side) with the hanging portion 990B of the drape 990 for the operating table lifted.

[0045] Here, although a part of the contaminated drape portion covering the X-ray detector 92 and the contaminated portion APP2 of the drape 910 for the arm is located in the clean field above the boundary region BA, since it is covered by the hanging portion 990B of the drape 990 for the operating table, the possibility of these becoming a risk of surgical field contamination is low. However, since the contaminated portion OPP1 of the hanging portion 990B of the drape 990 for the operating table is located in the clean field above the boundary region BA, this has a high possibility of becoming a risk of surgical field contamination.

[0046] For example, if an operator such as an orthopedic surgeon (operating surgeon) or an assistant touches the contaminated portion OPP1 in order to support the lifting of the hanging portion 990B of the drape 990 for the operating table by the X-ray detector 92, the operator's hand will also be contaminated, resulting in a risk of surgical field contamination. Also, for example, if the hanging portion 990B of the drape 990 for the operating table is lifted by the X-ray detector 92 and the contaminated portion OPP1 is located in the clean area, and the contaminated portion OPP1 comes into contact with the operator's surgical gown, the operator's surgical gown will also be contaminated, resulting in a risk of surgical field contamination.

[0047] As described above, in the conventional operating table drape 990, when changing from the AP view to the LATERAL view, the contaminated portion OPP1 moves to the clean area, which may lead to contamination of the surgical field and thus poses a problem.

[0048] FIG. 6 is a diagram showing the contamination states of the conventional arm drape 910 and the operating table drape 990 after returning from the LATERAL view shown in FIG. 5 to the AP view. For supplementary explanation, the AP view shown in FIG. 6 is a state in which the arm 93 is rotated 90 degrees in the direction of arrow k2 from the LATERAL view shown in FIG. 5. Note that FIG. 6 shows an external configuration example of the fluoroscopic imaging device 90 covered with the conventional arm drape 910 and the operating table O covered with the conventional operating table drape 990 from the side.

[0049] In the example shown in FIG. 6, there is no newly contaminated portion on the arm drape 910, and the contaminated portion of the arm drape 910 remains as the contaminated portion APP2. However, as a result of returning from the LATERAL view to the AP view, the portion of the contaminated portion APP2 that was contaminated in the LATERAL view has moved to the clean area above the boundary region BA, so there is a high possibility of becoming a risk of surgical field contamination.

[0050] FIG. 7 is an explanatory diagram showing an example of the principle in which the contaminated portion APP2 of the arm drape 910 in the prior art poses a risk of surgical field contamination. FIG. 7 shows a state in which the fluoroscopic imaging device 90 is withdrawn from the state shown in FIG. 6, and the orthopedic surgeon S and the assistant AS resume the operation on the patient P lying supine on the operating table O.

[0051] When withdrawing the fluoroscopic imaging device 90 from the state shown in FIG. 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, among the hanging portion 990A of the operating table drape 990, the portion located above the boundary region BA becomes the contaminated portion OPP2.

[0052] If the operation is resumed in this state, there is a high probability that the contaminated part OPP2 of the hanging part 990A of the surgical drape 990 for the operating table will come into contact with the surgical gown of the assistant AS. As a result, the part of the surgical gown of the assistant AS that comes into contact with the contaminated part OPP2 becomes a contaminated part ASPP and is contaminated, which poses a risk of surgical field contamination.

[0053] During the operation, the orthopedic surgeon S and the assistant AS may also switch positions. In this case as well, the surgical gown of the orthopedic surgeon S comes into contact with the contaminated part OPP2, resulting in the contamination of the surgical gown of the orthopedic surgeon S and posing a risk of surgical field contamination. Also, the contaminated part ASPP of the assistant AS who has switched positions comes into contact with the hanging part 990B of the surgical drape 990 for the operating table, contaminating the part located above the boundary area BA of the hanging part 990B and posing a risk of surgical field contamination.

[0054] As described above, in the conventional arm drape 910 and surgical drape 990 for the operating table, although both are contaminated in the unclean area, they may enter the clean area in a contaminated state, thus posing a risk of surgical field contamination.

[0055] Hereinafter, the medical drape of the present embodiment that reduces the risk of surgical field contamination will be described. First, the arm drape of the present embodiment will be described.

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

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

[0058] The drape main body 111 is the main body portion of the drape 110 for the arm that covers the arm 13. The drape main body 111 is bag-shaped, and at least the lower end 112 is open. Since the drape 110 for the arm in the present embodiment has such a bag shape, the drape main body 111 covers the arm 13 by covering the arm 13 from above. That is, in the present embodiment, the drape 110 for the arm covers the arm 13 by covering the drape main body 111 from 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 an outer peripheral width that can cover at least not only the arm 13 but also the X-ray source 11.

[0059] Further, the drape main body 111 is locked to the arm support portion 14 when the arm 13 rotates in the forward direction, and a notch 113 is formed to prevent the drape main body 111 from following the arm 13. Specifically, the notch 113 is formed at the lower end of the drape main body 111 and prevents the drape main body 111 from following the arm 13 on the upper end side. In the present embodiment, as shown in FIGS. 8 to 10, the drape main body 111 has a semi-elliptical notch 113 on the lower end side of its back surface. In the present embodiment, as shown in FIGS. 8 to 10, the lower end side of the drape main body 111 where the notch 113 is located may be referred to as the lower end portion 111A, and the upper end side of the drape main body 111 above the notch 113 may be referred to as the upper end portion 111B.

[0060] The shape of the notch 113 is not limited to the examples shown in FIGS. 8 to 10. Although details will be described later, the notch 113 is provided in the drape body 111 so that when the arm 13 is covered with the arm drape 110, parts of the X-ray fluoroscopy apparatus 10 other than the arm 13 are positioned within this notch 113. Thereby, when the arm 13 rotates in the direction of arrow a1, the upper end portion 111B of the drape body 111 can be accumulated in parts of the X-ray fluoroscopy apparatus 10 other than the arm 13 without entering the unclean area. In the present embodiment, a case where the part other than the arm 13 of the X-ray fluoroscopy apparatus 10 is the arm support portion 14 will be described as an example, but it is not limited thereto. Depending on the structure of the X-ray fluoroscopy apparatus 10, parts other than the arm support portion 14 such as the main body portion 15 can also be considered.

[0061] Therefore, as long as the above object can be achieved, the shape of the notch 113 does not matter. For example, the notch 113 may be a rectangular shape, a triangular shape, or the like. Further, the notch 113 may be a planar shape or a three-dimensional shape. Also, as long as the above object can be achieved, instead of the notch 113 in the first place, it may be a slit or the like formed on the lower end side of the drape body 111. Hereinafter, it will be described that the notch 113 can be replaced with a slit.

[0062] The locking member 114 is provided on the drape body 111, engages the drape body 111 with the arm support portion 14, and prevents at least a part of the drape 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 side of the drape body 111 from following the arm 13. In the drape body 111, it is provided above the notch 113. The locking member 114 is a member for connecting the drape body 111 to a part other than the arm 13 of the fluoroscopic imaging apparatus 10. As described above, in this embodiment, the case where the part other than the arm 13 of the fluoroscopic imaging apparatus 10 is the arm support portion 14 is taken as an example for explanation, but it is not limited thereto. In this embodiment, as shown in FIGS. 9 to 10, the arm drape 110 has an arc-shaped adhesive tape as the locking member 114.

[0063] Although details will be described later, the locking member 114 is a member for engaging the arm support portion 14 and applying a downward (-z direction) tension so that the lower end portion 111A of the drape body 111 does not enter the clean area when the arm 13 rotates in the direction of arrow a2. Therefore, as long as the above object can be achieved, the type and shape of the locking member 114 do not matter. For example, the locking member 114 may be an adhesive member for fixing the drape body 111 to the arm support portion 14. Examples of the adhesive member include, but are not limited to, adhesive tapes and magnetic tapes. Also, for example, the locking member 114 may be an engaging member for engaging the drape body 111 with the arm support portion 14. Examples of the engaging member include, but are not limited to, hooks that catch on the arm support portion 14. In this embodiment, the position on the drape body 111 where the locking member 114 is provided is above the notch 113, but as long as the above object can be achieved, the position also does not matter.

[0064] FIG. 11 is a side view showing an example of a state in which the arm 13 included in the fluoroscopic imaging apparatus 10 of the present embodiment is covered with the arm drape 110 of the present embodiment. FIG. 12 is a rear view showing an example of a state in which the arm 13 included in the fluoroscopic imaging apparatus 10 of the present embodiment is covered with the arm drape 110 of the present embodiment. Note that FIGS. 11 and 12 show the fluoroscopic imaging apparatus 10 in the AP view. In FIG. 11, the operating table O and the patient P are also shown, but in FIG. 12, the illustration of the operating table O and the patient P is omitted.

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

[0066] The arm drape 110 is positioned such that the notch 113 of the drape body 111 is located at the arm support portion 14. Specifically, as shown in FIGS. 11 and 12, by positioning the semi-elliptical notch 113 of the drape body 111 at the arm support portion 14, the drape body 111 straddles the arm support portion 14. As a result, on the upper end portion 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 portion 111A side of the drape body 111, the drape body 111 covers the arm 13 in an apron shape or a skirt shape.

[0067] The arm drape 110 is connected to the arm support portion 14 by a locking member 114. Specifically, as shown in FIGS. 11 and 12, the drape body 111 is fixed to the arm support portion 14 by attaching the locking member 114, which is an adhesive seal provided on the upper part of the notch 113, to the connection portion 14B of the arm support portion 14.

[0068] The arm drape 110 of this embodiment covers the arm 13 as described above. When the outer peripheral width of the drape main body 111 is too large compared to the outer peripheral 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, a string, or the like. However, although details will be described later, in this embodiment, it is necessary for the arm 13 to be rotatable with respect to the drape main body 111. Therefore, when fixing the upper end portion 111B of the drape main body 111 to the arm 13 with a tape member, a string, or the like, it is necessary to leave a certain margin.

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

[0070] FIG. 13 is a diagram showing the contamination state in the AP view of the arm drape 110 of this embodiment. In FIG. 13, an example of the external configuration of the X-ray fluoroscopy imaging apparatus 10 covered with the arm drape 110 of this embodiment is shown from the side. In FIG. 13, since the main purpose is to explain the principle by which the arm drape 110 can reduce the risk of surgical field contamination, the drape for the operating table of this embodiment is not shown.

[0071] In the example shown in FIG. 13, the area below the boundary region BA (in the -z direction side) is the unclean area. Therefore, the portion of the arm drape 110 located below the boundary region BA is shown as the contaminated portion APP of the arm drape 110. In the example shown in FIG. 13, the contaminated portion APP is represented by hatching with diagonal lines that are closer together than those of the arm drape 110. The contaminated portion APP mainly corresponds to the portion of the lower end 111A of the drape main body 111 that covers the arm 13 in an apron shape or a skirt shape.

[0072] FIG. 14 is a diagram showing the contamination state of the arm drape 110 of the present embodiment after changing from the AP view shown in FIG. 13 to the LATERAL view. Supplementary note, the LATERAL view shown in FIG. 14 is a state where the arm 13 is rotated 90 degrees in the direction of arrow a1 from the AP view shown in FIG. 13. Note that FIG. 14 shows an external configuration example of the fluoroscopic imaging apparatus 10 covered with the arm drape 110 of the present embodiment with the arm 13 from the side.

[0073] In the present embodiment, as described above, the arm 13 is rotatable with respect to the drape main body 111, and unlike the prior art, the arm and the drape main body do not rotate synchronously from the beginning to the end. For this reason, in the present embodiment, when one end of the arm 13 is rotated in the direction approaching the arm support portion 14, the upper portion of the drape main body 111 above the notch 113 is accumulated on the arm support portion 14 while being crushed. Specifically, as shown in FIG. 14, even when the arm 13 rotates in the direction of arrow a1, the upper end portion 111B of the drape main body 111 only rotates in synchronization with the arm 13 up to the arm support portion 14. Then, when the upper end portion 111B of the drape main body 111 reaches the arm support portion 14 where the notch 113 is located, it is accumulated on the arm support portion 14 while being crushed. That is, when the arm 13 rotates in the direction of arrow a1 (forward direction), since the notch 113 is locked to the arm support portion 14, the upper end portion 111B of the drape main body 111 does not follow the arm 13 and is accumulated and stays on the arm support portion 14. If the arm support portion 14 is not in the shape shown in the figure, a fixing tool for preventing following, a locking portion, etc. may be provided at an appropriate position of the upper end portion 111B of the drape main body 111.

[0074] Also, the lower end portion 111A of the drape main body 111, which is mainly the contaminated portion APP, is not fixed to the arm 13 and only covers the arm 13 in an apron shape or a skirt shape, so its position does not change even when the arm 13 rotates in the direction of arrow a1.

[0075] As described above, even when the arm drape 110 of the present embodiment changes from the AP view to the LATERAL view, the portion located in the clean area above the boundary area BA (on the +z direction side) only accumulates while being crushed on the arm support portion 14 and remains in the clean area.

[0076] Subsequently, a 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 will be described. Since this state is the same as the state of the AP view shown in FIG. 13 described above, it will be described below with reference to FIG. 13.

[0077] In the present embodiment, when one end of the arm 13 is rotated in the reverse direction away from the arm support portion 14, the upper portion of the drape main body 111 that has accumulated while being crushed on the arm support portion 14 is returned to a state of 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 portion 14 is pulled by the rotation of the arm 13 and returned to the original state of covering the arm 13 shown in FIG. 13. That is, 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 portion 114 so that the upper end portion 111B of the drape main body 111 follows the arm 13 and returns to the original state.

[0078] In the present embodiment, the locking member 114 is an adhesive tape that is disposed at the top of the notch 113 and attached to the arm support portion 114 to prevent the portion of the drape body 111 below the notch 113 from being lifted above the arm support portion 114 when one end of the arm 13 is rotated counterclockwise in a 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 side) tension so that the lower end portion 111A of the drape body 111 remains in the region below the boundary region BA (-z direction side) so that the contaminated portion APP of the drape body 111 does not move to the clean field above the boundary region BA (+z direction side) due to being pulled by the rotation of the arm 13.

[0079] As described above, in the arm drape 110 of the present embodiment, when the arm 13 rotates in the forward direction, the notch 113 of the drape body 111 prevents the drape body 111 from following the arm 13, while when the arm 13 rotates in the reverse direction, the locking member 114 locks the drape body 111 to prevent the drape body 111 from following the arm 13. Even when the arm drape 110 of the present embodiment changes from the LATERAL VIEW to the AP VIEW, the portion that accumulates while being crushed on the arm support portion 14 only returns to the original covering state and remains located in the clean field above the boundary region BA. Since the arm drape 110 returns to the original covering state when changing from the LATERAL VIEW to the AP VIEW, the arm 13 does not move to the clean field above the boundary region BA without being covered by the arm drape 110. Further, even when the arm drape 110 of the present embodiment changes from the LATERAL VIEW to the AP VIEW, since the locking member 114 generates a downward tension, the contaminated portion APP of the drape body 111 does not move to the clean field above the boundary region BA (+z direction side).

[0080] As described above, regardless of the AP view or the LATERAL view, the portion of the drape body 111 of the arm drape 110 of the present embodiment located in the clean area does not move to the unclean area, and the portion of the drape body 111 located in the unclean area does not move to the clean area. Therefore, according to the arm drape 110 of the present embodiment, a situation where the contaminated portion of the drape body 111 enters the clean area does not occur, and the risk of contamination of the surgical field can be suppressed.

[0081] Next, as the medical drape of the present embodiment for reducing the risk of occurrence of surgical field contamination, the operating table drape of the present embodiment will be described.

[0082] FIG. 15 is a side view showing an example of a state in which a pocket portion 192 for forming a pocket 195 for accommodating a part of the X-ray detector 12 and the arm 13 is folded and stored on the operating table O in the operating table drape 190 of the present embodiment. FIG. 16 is a side view showing an example of a state in which the pocket portion 192 is opened to form the pocket 195 in the operating table drape 190 of the present embodiment. Note that FIG. 15 shows an external configuration example of the X-ray fluoroscopy imaging apparatus 10 and the arm drape 110 in the AP view from the side in addition to the operating table O covered with the operating table drape 190 of the present embodiment. FIG. 16 shows an external configuration example of the X-ray fluoroscopy imaging apparatus 10 and the arm drape 110 in the LATERAL view from the side in addition to the operating table O covered with the operating table drape 190 of the present embodiment.

[0083] As shown in FIGS. 15 and 16, the operating table drape 190 has a covering portion 191, a pocket portion 192, and a fixing portion 193. The covering portion 191, the pocket portion 192, and the fixing portion 193 are integrally formed on the operating table drape 190.

[0084] The covering portion 191 is a portion of the operating table drape 190 that covers the operating table O.

[0085] The pocket portion 192 is a portion of the operating table drape 190 for forming a pocket 195 that houses a part of the X-ray detector 12 and the arm 13. The pocket portion 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 portion 192 is normally folded and stored on the operating table O. In the example shown in FIG. 15, the pocket portion 192 is stored between the patient P and the operating table O.

[0086] Also, when the other end of the arm 13, which is 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 houses the other end of the arm 13 that passes upward from below through the side portion of the operating table O. Specifically, as shown in FIG. 16, the pocket portion 192 forms a pocket 195 that houses a part of the X-ray detector 12 and the arm 13 that passes upward from below through the side portion of the operating table O when the arm 13 rotates in the direction of arrow a1, in the clean field above the boundary region BA (+z direction side). Note that the formation of the pocket 195 by the pocket portion 192 is assumed to be performed manually by an operator such as an assistant, for example, but is not limited thereto.

[0087] The fixing 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 FIGS. 15 and 16, the fixing portion 193 is fixed to the floor surface by placing the weight 194 thereon.

[0088] As described above, when the pocket portion 192 is not used, such as during an AP view, the operating table drape 190 of the present embodiment is stored on the operating table O located in the clean field above the boundary region BA (+z direction side). Also, even when the pocket portion 192 is used, such as during a LATERAL view, the operating table drape 190 of the present embodiment can form a pocket in the clean field above the boundary region BA (+z direction side).

[0089] As described above, in the operating table drape 190 of the present embodiment, regardless of whether it is an AP view or a LATERAL view, the pocket portion 192 is always located in the clean area and does not move to the dirty area. Therefore, according to the operating table drape 190 of the present embodiment, the pocket portion 192 is not contaminated in the dirty area, so a situation where the contaminated portion of the pocket portion 192 enters the clean area does not occur, and the risk of surgical field contamination can be suppressed. Further, according to the present embodiment, since the fixing portion 193 is fixed to the floor surface by the weight 194, when the pocket 195 houses a part of the X-ray detector 12 and the arm 13, the operating table drape 190 does not bounce up due to recoil, and a situation where a contaminated portion located in the dirty area below the boundary region BA (the -z direction side) moves to the clean area does not occur, and the risk of surgical field contamination can be suppressed.

[0090] Thus, according to the arm drape 110 and the operating table drape 190 of the present embodiment, a situation where a portion contaminated in the dirty area enters the clean area as in the prior art does not occur, so the risk of surgical field contamination can be significantly suppressed, and the risk of causing postoperative infectious diseases and the like can also be significantly suppressed. Further, according to the arm drape 110 and the operating table drape 190 of the present embodiment, a situation where a portion contaminated in the dirty area enters the clean area as in the prior art does not occur, so there is no need to replace these drapes during the operation, and the occurrence of various costs such as the cost of the drapes, the time cost in the operation, and the labor cost can also be suppressed.

[0091] (Modification 1) In the above embodiment, the method of fixing the upper end portion 111B of the drape main body 111 to the arm 13 was entrusted to an operator such as an orthopedic surgeon or an assistant. However, for an inexperienced operator such as a novice, there is a possibility that they may not know how much margin to leave when fixing the upper end portion 111B to the arm 13. Therefore, in the modification, a method that allows an inexperienced operator such as a novice to easily fix the upper end portion 111B to the arm 13 will be described.

[0092] FIG. 17 is a side view showing an example of a state in which an arm 13 included in the fluoroscopic imaging apparatus 10 of the modification is covered with an arm drape 210 of the modification. In the example shown in FIG. 17, it is different from the above-described embodiment in that the arm drape 210 further has adjustment members 220A and 220B for adjusting the outer peripheral width of the drape body 111. Since the adjustment members 220A and 220B are members having the same function and structure, hereinafter, the adjustment member 220A will be described, and the description of the adjustment member 220B will be omitted.

[0093] The adjustment member 220A is a member that adjusts the outer peripheral width of the drape body 111 so that the arm 13 can rotate with respect to the drape body 111 in a state where the arm 13 is covered with the drape body 111. The adjustment member 220A includes, for example, a tape member disposed in the width direction of the drape body, but is not limited thereto. In the modification, the adjustment members 220A and 220B are disposed in the longitudinal direction of the drape body 111, but the number of adjustment members disposed on the drape body 111 is not limited thereto, and may be any number as long as it is 1 or more. However, the location where the adjustment member is disposed is preferably the upper end portion 111B of the drape body 111.

[0094] FIG. 18 is a cross-sectional view of the arm drape 210 at the position where the adjustment member 220A of the modification is disposed. As shown in FIG. 18, the adjustment member 220A has an adhesive portion 221 at one end thereof and is fixed to the drape body 111. The adjustment member 220A also has a weak adhesive portion 222 with a weak adhesive force and an adhesive portion 223 sealed with a mount at the other end on the opposite side. The weak adhesive portion 222 is an adhesive portion for temporarily fixing the adjustment member 220A to the drape body 111. In addition, on the drape body 111, adhesive portions 231 to 234 of the adhesive portion 223 are shown in the width direction at the position where the adjustment member 220A is disposed. The adhesive portions 231 to 234 each show how much the outer peripheral width of the drape body 111 can be adjusted when the adhesive portion is fixed with the adhesive portion 223.

[0095] For example, assume that the radius of the drape body 111 is 20 cm, the outer peripheral width of the drape body 111 is 120 cm, and the length of the adjustment member 220A is 60 cm. In this case, it is shown that at the adhesion point 231, if the adhesive portion 223 is fixed at the adhesion point 231, the outer peripheral width of the drape body 111 can be adjusted to 100 cm. Also, at the adhesion point 232, it is shown that if the adhesive portion 223 is fixed at the adhesion point 232, the outer peripheral width of the drape body 111 can be adjusted to 90 cm. Further, at the adhesion point 233, it is shown that if the adhesive portion 223 is fixed at the adhesion point 233, the outer peripheral width of the drape body 111 can be adjusted to 80 cm. Additionally, at the adhesion point 234, it is shown that if the adhesive portion 223 is fixed at the adhesion point 234, the outer peripheral width of the drape body 111 can be adjusted to 70 cm. Therefore, for example, as shown in FIG. 19, if the adhesive portion 223 is fixed at the adhesion point 233, the outer peripheral width of the drape body 111 can be adjusted from 120 cm to 80 cm by the adjustment member 220A.

[0096] According to the modification as described above, even an inexperienced operator such as a novice can easily adjust the width of the upper end portion 111B of the drape body 111 to a targeted length, and the arm 13 can fix the drape for arm 210 to the arm 13 to an extent possible. Also, according to the modification, since the width of the upper end portion 111B of the drape body 111 can be adjusted in multiple steps, it can widely accommodate a plurality of types of fluoroscopic X-ray imaging apparatuses 10 having different arm widths.

[0097] (Modification 2) In the above embodiment, the case where the locking member 114 is an adhesive tape has been described as an example, but it may also be a magnetic tape. In this case, a magnetic tape may be provided not only on the drape body 111 side but also on the arm support portion 14 side.

[0098] (Modification 3) In the above embodiment, the case where the drape main body 111 is bag-shaped has been described as an example, but the present invention is not limited to this, and it may be a cylindrical shape with both ends open. In this case, the upper end may be tied with a string or the like. Further, for example, the drape main body 111 may be formed in the shape of a single piece of cloth instead of a bag shape, and only the portion corresponding to the upper end portion may be realized by connecting both ends of the side portions with a fastener, tape, button, or the like.

[0099] The above-described embodiments and each modification example merely show an example of concretization in implementing the present disclosure, and the technical scope of the present disclosure should not be construed in a limited manner by these. That is, the present disclosure can be implemented in various forms without departing from the gist or the main features thereof. Further, the above-described embodiments and each modification example can be implemented in appropriate combination.
