[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The present application is further described in detail below with reference to the accompanying drawings.

[0037] The embodiments of the present application disclose an extension device for extending the length of an operating table and a method of using the same.

[0038] like Figure 1 As shown, an extension device for extending the length of an operating table includes an extension table body 1, a locking assembly 2, and a height adjustment assembly 3. The extension table body 1 is detachably mounted on an operating table 5; the locking assembly 2 is used to connect the extension table body 1 and the operating table 5; the height adjustment assembly 3 is disposed below the extension table body 1 and is used to adjust the height of the extension table body 1.

[0039] By using the height adjustment component 3 to adjust the height of the extension bed body 1, the height of the extension bed body 1 reaches the connection height, and then by using the locking component 2 to connect the extension bed body 1 to the operating bed 5, the extension operation of the operating bed 5 is realized. After that, the patient's head, chest, abdomen and other upper limbs can lie on the extension bed body 1, and the pelvis and lower limbs can lie on the operating bed 5, so that the lower limbs can be exposed to the fluoroscopic field of view, so as to facilitate interventional surgery on the lesions of the lower limbs, thereby solving the problem that the existing floor-standing digital subtraction angiography equipment cannot cover the distal blood vessels of the lower limbs in the head-first position.

[0040] like Figure 1 and Figure 2As shown, the extension bed body 1 includes an upper limb support bed 11 and a connecting member 12 . The connecting member 12 is arranged on the upper limb support bed 11 , and the locking assembly 2 connects the connecting member 12 and the operating bed 5 .

[0041] Specifically, the connecting member 12 is provided at one end of the upper limb against the bed 11 .

[0042] Move the extension bed body 1 so that the extendable operating bed 5 is placed close to the operating bed 5, and adjust the height of the extension bed body 1 by controlling the height adjustment component 3 so that the upper surface height of the connecting piece 12 is the same as the lower surface height of the operating bed 5 or the lower surface height of the connecting piece 12 is the same as the upper surface height of the operating bed 5.

[0043] The connecting piece 12 overlaps and abuts against one end of the operating bed 5 , and then the locking assembly 2 is fixed at the position where the connecting piece 12 overlaps with the operating bed 5 , thereby achieving the connection between the extension bed body 1 and the operating bed 5 .

[0044] Afterwards, the patient's head, chest, abdomen and other upper limbs can lie on the upper limb support bed 11, and the pelvis and lower limbs can lie on the bed surface of the operating bed 5, so that the lower limbs can be exposed to the fluoroscopic field of view, so as to facilitate interventional surgery on the lesions of the lower limbs.

[0045] like Figure 1 、 Figure 2 and Figure 4 As shown, the connecting member 12 includes a supporting layer 121 and a connecting base layer 122 . The supporting layer 121 is used to contact the operating bed 5 , and the supporting layer 121 is an elastic soft layer.

[0046] Specifically, the abutment layer 121 is configured as an elastic soft layer. After the locking assembly 2 fixes the connector 12 and the operating bed 5 together, the abutment layer 121 can be pressed against the surface of the operating bed 5. The abutment layer 121 is compressed under force, thereby increasing the actual contact area between the abutment layer 121 and the operating bed 5, increasing the friction between the abutment layer 121 and the operating bed 5, and improving the stability of the connection between the connector 12 and the operating bed 5.

[0047] In this embodiment, the material of the elastic soft layer can be elastic rubber.

[0048] like Figure 1 、 Figure 2 and Figure 5 As shown, the locking assembly 2 includes a locking base 21 and a locking member 22. The locking member 22 is arranged on the locking base 21, and the locking member 22 moves toward or away from one side of the locking base 21. The connecting member 12 and the operating bed 5 are arranged between one side of the locking base 21 and the locking member 22.

[0049] Specifically, in order to improve the stability of the connection between the connecting member 12 and the operating bed 5 , at least two locking assemblies 2 are provided, and the at least two locking assemblies 2 are respectively spaced apart and arranged on both sides of the connecting member 12 .

[0050] In this embodiment, two locking assemblies 2 are provided, and the two locking assemblies 2 are respectively provided on both sides of the connecting member 12 .

[0051] Compared with only setting the locking assembly 2 on one side where the connecting member 12 and the operating bed 5 overlap, it can prevent the other side from rotating due to the lack of the locking assembly 2, thereby reducing the stability of the connection between the connecting member 12 and the operating bed 5.

[0052] Now take one of the locking components 2 as an example for explanation:

[0053] The connecting member 12 and the operating bed 5 are arranged between one side of the locking base 21 and the locking member 22. The locking member 22 can move toward or away from one side of the locking base 21. When the connecting member 12 and the operating bed 5 are located between one side of the locking base 21 and the locking member 22, the locking member 22 is driven to move toward one side of the locking base 21, so that the connecting member 12 and the operating bed 5 are clamped between one side of the locking base 21 and the locking member 22, thereby achieving the purpose of the locking assembly 2 fixing the connecting member 12 and the operating bed 5.

[0054] like Figure 1 and Figure 5 As shown, a locking groove 211 is provided on the locking base 21, and the connecting member 12 and the operating bed 5 are arranged in the locking groove 211. A locking hole 212 is provided on one side of the locking groove 211. The locking member 22 is screwed to the locking hole 212, and the locking member 22 moves toward or away from the other side of the locking groove 211.

[0055] Specifically, when the connecting piece 12 overlaps and abuts one end of the operating bed 5, the locking groove 211 is used to embed the connecting piece 12 and the operating bed 5 into the locking groove 211. At this time, the locking piece 22 is rotated to move closer to or away from the other side of the locking groove 211 until the end of the locking piece 22 is tightly abutted against the connecting piece 12 or the operating bed 5, thereby achieving the purpose of the locking assembly 2 fixing the connecting piece 12 and the operating bed 5.

[0056] Furthermore, an auxiliary locking member 221 is provided at one end of the locking member 22 located on the outside. The auxiliary locking member 221 is arranged perpendicular to the locking member 22. The operator can rotate the auxiliary locking member 221 to move the locking member 22 toward or away from the other side of the locking groove 211.

[0057] The setting of the auxiliary locking member 221 increases the contact area with the operator's hand. At the same time, the setting of the auxiliary locking member 221 increases the lever arm. The operator can use relatively small hand strength to generate a sufficiently large torque to rotate the locking member 22, easily overcoming friction and medium pressure.

[0058] Furthermore, a locking pad 222 is provided at one end of the locking member 22 located in the locking groove 211. The surface area of ​​the locking pad 222 is larger than the cross-sectional area of ​​the locking member 22. When the connecting member 12 and the operating bed 5 are embedded in the locking groove 211, the auxiliary locking member 221 is rotated to drive the locking member 22 to move toward the other side of the locking groove 211 until the locking pad 222 is pressed against the connecting member 12 or the operating bed 5.

[0059] The provision of the pressing pad 222 can reduce the stress concentration on the connecting member 12 or the operating bed 5 from the locking member 22 , thereby increasing the service life of the connecting member 12 or the operating bed 5 .

[0060] In this embodiment, the pressing pad 222 is a rubber pad.

[0061] Furthermore, when the locking assembly 2 is used to connect the extension bed body 1 and the operating bed 5 , the direction of the locking assembly 2 is adjusted so that the locking member 22 is located below the extension bed body 1 and the operating bed 5 .

[0062] When the surgeon rotates the locking piece 22, he or she needs to put his or her hand under the extension bed body 1 and the operating bed 5 to adjust it, thereby preventing the patient's movement space on the operating bed 5 from being reduced due to the locking piece 22 being set above the extension bed body 1 and the operating bed 5.

[0063] like Figure 1 Figure 2 and Figure 4 As shown, the connecting member 12 includes a connecting and fixing layer 123, and the connecting and fixing layer 123 and the abutting layer 121 are respectively arranged on both sides of the connecting base layer 122; the connecting and fixing layer 123 is used to abut against the locking member 22, and the connecting and fixing layer 123 is an elastic soft layer.

[0064] Specifically, when adjusting the height of the extension bed body 1 through the height adjustment component 3, the upper surface height of the connecting member 12 is adjusted to be the same as the lower surface height of the operating bed 5, so that the connecting member 12 is located below the operating bed 5, and the abutment layer 121 is located above the connecting base layer 122, and the abutment layer 121 can abut against the lower surface of the operating bed 5.

[0065] The connection fixing layer 123 is located below the connection base layer 122 , and the abutting pad 222 can abut against the connection fixing layer 123 .

[0066] The connecting and fixing layer 123 is set as an elastic soft layer. When the pressing pad 222 abuts against the connecting and fixing layer 123, the connecting and fixing layer 123 can be slightly concave, thereby increasing the actual contact area between the connecting and fixing layer 123 and the pressing pad 222, improving the friction between the connecting and fixing layer 123 and the pressing pad 222, and improving the stability of the connection between the connecting and fixing layer 123 and the pressing pad 222.

[0067] In this embodiment, the connection fixing layer 123 is made of elastic rubber.

[0068] Furthermore, a slot can be set on the lower surface of the operating bed 5. When using the locking assembly 2 to connect the extension bed body 1 and the operating bed 5, the end of the connecting piece 12 away from the upper limb against the bed 11 is inserted into the slot to improve the stability of the connection between the extension bed body 1 and the operating bed 5.

[0069] like Figure 1 and Figure 3 As shown, the thickness of the upper limb support bed 11 is greater than the thickness of the connecting member 12 , and the thickness of the upper limb support bed 11 is less than or equal to the thickness of the connecting member 12 plus the thickness of the operating bed 5 .

[0070] Specifically, the thickness of the upper limb support bed 11 is equal to the thickness of the connecting member 12 plus the thickness of the operating bed 5. With this arrangement, when the connecting member 12 is positioned below the operating bed 5 and the connecting member 12 and the operating bed 5 are secured together via the locking assembly 2, the upper surface of the upper limb support bed 11 is approximately at the same height as the upper surface of the operating bed 5, thereby increasing the comfort of the patient while lying on both the extension bed body 1 and the operating bed 5.

[0071] like Figure 1 、 Figure 2 and Figure 3 As shown, the upper limb rest bed 11 includes an imaging layer 111 and a rest base layer 112 . The imaging layer 111 is arranged on the rest base layer 112 , and the height adjustment component 3 is arranged on a side of the rest base layer 112 away from the imaging layer 111 .

[0072] Specifically, the imaging layer 111 is disposed on the upper surface of the base layer 112 , and the imaging layer 111 is made of carbon fiber.

[0073] Existing metal bed boards easily produce stripe or grid-like artifacts on images, interfering with doctors' judgment of vascular lesions.

[0074] The imaging layer 111 is made of carbon fiber material, which produces almost no artifacts and can provide a "cleaner" image background, thereby improving the accuracy of diagnosis and surgical operations.

[0075] like Figure 1 and Figure 2As shown, the extension device for extending the length of the operating bed includes an upper limb fixing part 4, which is arranged on the extension bed body 1 and is used to fix the position of the patient's upper limb on the extension bed body 1.

[0076] Specifically, the upper limb fixing member 4 is arranged at one end of the upper limb supporting bed 11 close to the connecting member 12 , and the upper limb fixing member 4 includes a first fixing belt 41 and a second fixing belt 42 , which are respectively arranged on both sides of the upper limb supporting bed 11 .

[0077] The first fixing belt 41 and the second fixing belt 42 are detachably connected, and specific detachable connection methods include buckle connection and bonding, etc. In this embodiment, the first fixing belt 41 and the second fixing belt 42 are bonded, and both the first fixing belt 41 and the second fixing belt 42 are Velcro fixing belts.

[0078] When the patient's upper limbs are against the upper limb support bed 11, the first fixing belt 41 and the second fixing belt 42 can be used to restrain the patient, which can not only prevent the patient from falling from the upper limb support bed 11, but also prevent the patient from shaking during surgical treatment and affecting the surgeon's normal surgical operation.

[0079] Furthermore, a plurality of first fixing straps 41 and second fixing straps 42 may be provided, with the plurality of first fixing straps 41 and the plurality of second fixing straps 42 being spaced apart and arranged on both sides of the upper limb resting against the bed 11. The provision of multiple first fixing straps 41 and second fixing straps 42 not only further stabilizes the patient's upper limb from shaking, but also allows different numbers or positions of first fixing straps 41 and second fixing straps 42 to be bonded according to the patient's body shape.

[0080] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, in one implementation of this example, the height adjustment assembly 3 includes a first support member 31 and a second support member 32, one end of the first support member 31 is rotatably set on the upper limb support bed 11, and the second support member 32 is rotatably connected to the first support member 31; a plurality of adjustment blocks 1121 are arranged at intervals on the upper limb support bed 11, and the gap between adjacent adjustment blocks 1121 is an adjustment gap 1122, and one end of the second support member 32 is used to be clamped into the adjustment gap 1122.

[0081] Specifically, the plurality of adjustment blocks 1121 are arranged on the lower surface of the base layer 112 , and the plurality of adjustment blocks 1121 are arranged on a side of the base layer 112 away from the connecting member 12 .

[0082] One end of the first support member 31 is rotatably disposed against the lower surface of the base layer 112 and close to the connecting member 12 .

[0083] The middle portion of the second support member 32 is rotatably connected to the middle portion of the first support member 31 .

[0084] One end of the first support member 31 away from the base layer 112 and one end of the second support member 32 away from the base layer 112 can be in contact with the ground, and the other end of the second support member 32 can be clamped in a certain adjustment gap 1122, thereby achieving a stable support and extension height position of the bed body 1.

[0085] When the height of the extended bed body 1 needs to be adjusted, one end of the second support member 32 is taken out from a certain adjustment gap 1122, and the second support member 32 is inserted into the corresponding adjustment gap 1122 according to the height to be adjusted. The height of the extended bed body 1 can be adjusted. The structure is simple, the operation is convenient, and the connection stability is strong.

[0086] Furthermore, universal wheels 33 are provided at one end of the second support member 32 away from the base layer 112 and at one end of the first support member 31 away from the base layer 112 .

[0087] The universal wheels 33 can rotate 360 ​​degrees freely. The arrangement of the universal wheels 33 allows the extension bed body 1 to be flexibly moved in any direction. When the surgeon moves the operating bed 5, the extension device for extending the length of the operating bed can move synchronously with the operating bed 5 through the universal wheels 33.

[0088] In another implementation of this embodiment, the height adjustment assembly 3 includes a third support member, which is a retractable support member. One end of the third support member is arranged on the extended bed body, and the other end is used to contact the ground.

[0089] There are at least two third support members, and the at least two third support members are circumferentially arranged on the extended bed body 1 .

[0090] Furthermore, the third support member includes a receiving portion, a telescopic portion and a limiting member. One end of the receiving portion is arranged against the lower surface of the base layer 112, and the other end is provided with a telescopic hole, and the telescopic portion is slidably arranged in the telescopic hole.

[0091] A limiting hole is also provided on the accommodating portion, the limiting hole is communicated with the telescopic hole, and the limiting piece is screwed to the limiting hole.

[0092] The height of the extension bed body 1 and the operating bed 5 can be matched by adjusting the length of the telescopic part extending from the telescopic hole. After the height is determined, the limiter is screwed so that its end is pressed against the outer surface of the telescopic part located in the telescopic hole, thereby fixing the length of the third support member.

[0093] As shown in Figure *, an edge buffer strip is provided on the edge of the upper limb support bed 11. The edge buffer strip is an elastic buffer strip, which can be provided only on the support base layer 112, or only on the imaging layer 111, or on both the support base layer 112 and the imaging layer 111.

[0094] The provision of the edge buffer strips can prevent the extension bed body 1 from accidentally colliding with other people or equipment during movement, thereby preventing the extension bed body 1 from being damaged.

[0095] like Figure 7 As shown, a method for using an extension device for extending the length of an operating table is applied to any of the above-mentioned extension devices for extending the length of an operating table, and the method comprises:

[0096] S100, adjusting the height adjustment component 3 to control the height of the extended bed body 1 to reach the connection height.

[0097] Specifically, the connection height is the height from the lower surface of the operating table 5 to the ground.

[0098] Before connecting the extension bed body 1 to the operating bed 5, first determine the height of the operating bed 5 to be connected, and then adjust the height adjustment component 3 according to this height (such as inserting the second support member 32 into the corresponding adjustment gap 1122 or adjusting the length of the telescopic part of the third support member extending from the telescopic hole) to ensure that the height of the subsequent abutment layer 121 can abut against the lower surface of the operating bed 5.

[0099] S200 , controlling the locking assembly 2 to connect the extension bed body 1 to the operating bed 5 .

[0100] Specifically, first push the extension bed body 1 so that the connecting piece 12 extends to the bottom of the operating bed 5. The connecting piece 12 can be inserted into the slot to complete the pre-connection of the extension bed body 1 and the operating bed 5. Then, fix the locking assembly 2 at the position where the connecting piece 12 and the operating bed 5 overlap, thereby realizing the connection between the extension bed body 1 and the operating bed 5.

[0101] The specific connection method is: after the connecting piece 12 overlaps and abuts one end of the operating bed 5, the connecting piece 12 and the operating bed 5 are embedded in the locking groove 211 using the locking groove 211. At this time, the locking piece 22 is rotated to move closer to or away from the other side of the locking groove 211 until the end of the locking piece 22 is tightly abutted against the connecting piece 12 or the operating bed 5, thereby achieving the purpose of fixing the connecting piece 12 and the operating bed 5 by the locking assembly 2.

[0102] Afterwards, the patient's head, chest, abdomen and other upper limbs can lie on the extension bed body 1, and the pelvis and lower limbs can lie on the operating table 5, so that the lower limbs can be exposed to the fluoroscopic field of view, so as to facilitate interventional surgery on the lesions of the lower limbs, solving the problem that the existing floor-standing digital subtraction angiography equipment cannot cover the distal blood vessels of the lower limbs in the head-first position.

[0103] The patient then lies supinely on the extended bed and operating table 5 in a head-first position (the head, chest, and abdomen are on the extended bed; the pelvis and lower limbs are on the operating table 5). The surgeon then moves the groin area under the DSA fluoroscopic field of view for puncture and catheterization. The surgeon can also move the operating table 5, which is synchronized with the extended bed via universal wheels 33, allowing the lesion to be moved under the fluoroscopic field of view for interventional surgery.

[0104] In summary, an extension device for extending the length of an operating table includes an extension table body 1, a locking assembly 2, and a height adjustment assembly 3. The extension table body 1 is detachably mounted on an operating table 5; the locking assembly 2 is used to connect the extension table body 1 and the operating table 5; and the height adjustment assembly 3 is disposed below the extension table body 1 and is used to adjust the height of the extension table body 1.

[0105] By using the height adjustment component 3 to adjust the height of the extension bed body 1, the height of the extension bed body 1 reaches the connection height, and then by using the locking component 2 to connect the extension bed body 1 to the operating bed 5, the extension operation of the operating bed 5 is realized.
