Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an auxiliary device for supine spinal correction surgery. Background Art

[0002] In supine spinal correction surgery, the change in patient position is an important consideration, which directly affects the accuracy of the surgery and the final correction effect. That is, in the correction surgery of kyphosis, V-shaped osteotomy involving two vertebrae is often performed, and the osteotomized vertebrae of the patient are fused and fixed. In the process of fusing and fixing the two vertebrae, the surgeon needs to pressurize the patient's spine downward to achieve the purpose of anatomical alignment. However, due to the resistance of the spinal bony structure (patient position) and surrounding muscles, manual pressure often cannot achieve the alignment requirements.

[0003] Currently, there are two solutions to change the patient's position clinically: one is for the assistant to leave the sterile area of ​​the operating table, lift the patient's shoulders, hips and lower limbs upward, passively flex the patient's position, and complete the alignment of the surgical site. However, this method requires manual intervention to change the position, and the operator needs to cross the boundary of the sterile area, which may easily cause contamination of the surgical sterile area. In addition, the line of sight is blocked by the sterile area sheet, and the patient's limb operations cannot be performed under direct vision. The second is to implant additional pressure screws into the patient's vertebral body, and use the tension of the screw rod to bend the patient's spine and position to an angle for surgery. Due to the implantation of screws, the screw rods are prone to loosening and breaking, which brings great risks to the operation.

[0004] Common angle-adjustable beds are used to change the height of the patient's limbs when placing the patient before surgery. If they are used for angle adjustment during surgery, the bed will bounce up or down in a pulsed manner, and the angle change is not continuous and stable, with a large amplitude, making it difficult to perform fine adjustments. In addition, sudden excessive lifting of the angle is very likely to cause the patient's spinal fracture, and will cause great shaking to the patient's surgical site, leading to surgical failure.

[0005] It can be seen that the above-mentioned devices or methods all have the problem of being unable to achieve a safe and stable change in the patient's position during surgery. Therefore, for supine spinal correction surgery, it is of great significance to study an auxiliary device that can safely and stably change the patient's position during surgery.

[0017] In some embodiments, the two mattresses have different lengths; the preset angle range of the longer mattress is 0 to 22.5°, and the preset angle range of the shorter mattress is 0 to 30°.

[0018] In some embodiments, the preset angle ranges of the two mattresses are the same.

[0019] In some of the embodiments, when the inclined airbag is in an inflated state, the length of the inclined airbag is the same as the width of the mattress body.

[0020] In some of the embodiments, the mattress body is an inflatable air bag. When the mattress body is in an inflated state, the load-bearing surface of the mattress body is inclined, and the load-bearing surface of the mattress body is inclined toward the adjacent mattress.

[0021] In some embodiments, the rotating member includes a rotating shaft, a first connecting member and a second connecting member; the first connecting member and the second connecting member are both sleeved outside the rotating shaft, and the first connecting member and the second connecting member are both rotatably connected to the rotating shaft; the first connecting member is connected to any one of the mattresses, and the second connecting member is connected to the other mattress.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] In order to solve the above problems, the utility model provides an auxiliary device for supine spinal correction surgery, such as Figures 1 to 3 As shown, it includes two deformable mattresses 1 and a rotating member 2; along the length direction of the mattress 1, the two mattresses 1 are arranged in sequence, and a rotating member 2 is provided between adjacent mattresses 1, and the rotating member 2 is connected to the two mattresses 1, and the two mattresses 1 are connected to the rotating member 2 to form a rotatable and adjustable angle; the mattress 1 includes an elastically deformable shell 10, a mattress body 11, a tilting airbag 12 and an air pump member 13; the mattress body 11 is arranged in the shell 10; the tilting airbag 12 is arranged between the mattress body 11 and the inner bottom surface of the shell 10, the tilting airbag 12 is arranged on the side of the mattress body 11 away from the adjacent mattress 1, and the tilting airbag 12 is arranged along the width direction of the mattress 1; the air pump member 13 is connected to the tilting airbag 12, and the air pump member 13 is used to control the inflation and deflation of the tilting airbag 12; when the tilting airbag 12 is inflated, the load-bearing surface of the mattress 1 is tilted within a preset angle range.

[0036] After adopting the above-mentioned setting mode, since the two mattresses 1 can be rotatably connected by the rotating member 2, when in use, the two mattresses 1 are connected with the rotating member 2 to form a rotatable angle to facilitate the use needs of the user; and, since the tilting airbag 12 in this solution is arranged between the mattress body 11 and the inner bottom surface of the shell 10, the tilting airbag 12 is arranged on the side of the mattress body 11 away from the adjacent mattress 1, and the tilting airbag 12 is arranged along the width direction of the mattress 1; the air pump member 13 is connected to the tilting airbag 12, and the air pump member 13 is used to control the inflation and deflation of the tilting airbag 12; therefore, when in use, when the air pump member 13 inflates the tilting airbag 12, the load-bearing surface of the mattress 1 will tilt as the inflation amount increases, the load-bearing surface of the mattress 1 is tilted more continuously, and the body position of the user on the mattress 1 can also be safely and stably adjusted and changed, avoiding the problem of unsafe and unstable patient position adjustment caused by manual operation or pulse-type upward or downward angle adjustment of the bed as in the prior art.

[0037] like Figure 3 As shown, regarding the specific structure of the above-mentioned mattress 1, the mattress 1 is composed of a deformable shell 10, a mattress body 11, a tilting airbag 12 and an air pump component 13. The mattress body 11 and the tilting airbag 12 are both arranged in the deformable shell 10. When in use, since the shell 10 is deformable, the inflation of the tilting airbag 12 can make the mattress body 11 tilt at a preset angle.

[0038] For the above-mentioned tilting airbag 12, preferably, as Figure 3 The inclined airbag 12 shown is arranged horizontally at the bottom of the mattress body 11. The inclined airbag 12 is bonded to the mattress body 11. When the inclined airbag 12 is inflated, the length of the inclined airbag 12 is the same as the width of the mattress body 11. After adopting this setting, the inclined airbag 12 can provide stable support for the mattress body 11 after inflation.

[0039] For the above-mentioned mattress body 11, preferably, as Figure 3 The mattress body 11 shown is an inflatable air bag. When the mattress body 11 is inflated, the load-bearing surface of the mattress body 11 is inclined, and the load-bearing surface of the mattress body 11 is inclined toward the adjacent mattress 1. After adopting this setting method, on the one hand, the inflated mattress body 11 can improve the comfort of the patient, and on the other hand, the mattress body 11 itself can be tilted, so that more tilting angles can be selected for use.

[0040] Of course, in some possible embodiments, the mattress body 11 may be just an ordinary supporting mattress 1, which cannot be deformed. The mattress body 11 can only be tilted under the inflation support of the tilting airbag 12. Those skilled in the art can make a choice according to actual needs.

[0041] For the above-mentioned deformable shell 10, when the tilting airbag 12 in the shell 10 is not inflated, Figure 1 As shown, the overall shape of the housing 10 is a flat plate. When the tilt airbag 12 in the housing 10 is inflated, as shown in FIG. Figure 2 As shown, the overall shape of the housing 10 becomes triangular, that is, the side of the housing 10 away from the rotating member 2 is a triangular wide bottom, and the side of the housing 10 adjacent to the rotating member 2 is a triangular narrow angle.

[0042] For the above-mentioned air pump member 13, preferably, as Figure 3As shown, the air pump component 13 includes a ventilation group tube and a foot-operated inflation air pump; the ventilation group tube is arranged in the shell 10, one end of the ventilation group tube is connected to the tilting air bag 12, and the other end of the ventilation group tube extends out of the shell 10 and is connected to the foot-operated inflation air pump. After adopting this setting method, the inflation deformation of the head end or tail end mattress 1 can be controlled separately by the foot-operated switch during the operation, and the inflation deformation controlled by the switch can achieve the effect of changing the trunk angle of the patient in the prone position.

[0043] For example, during the main surgeon's operation, when the osteotomy is completed and the next step is to be closed, the surgeon only needs to step on the air pump foot switch that controls the inflation of the mattress 1, and the mattress 1 can be stably lifted to assist the patient's body bending angle. The surgeon can clearly observe in the surgical field that the V-shaped defect in the osteotomy area is gradually closed. When the required angle is reached, the surgeon releases the foot switch to proceed to the next surgical operation. The entire process does not require leaving the surgical sterile area, and no additional pressure screws need to be implanted.

[0044] Furthermore, in order to achieve differentiated adjustment of the patient's head and foot positions, e.g. Figure 2 and Figure 3 As shown, the preset angle ranges of the two mattresses 1 are different. After adopting this setting method, after the tilting airbag 12 is inflated, the two mattresses 1 can be tilted at different angles, and the formed angles are different to facilitate the patient's body position adjustment needs.

[0045] Preferably, if Figure 2 and Figure 3 As shown, at least one of the two mattresses 1 has a preset angle range of 0 to 30°, and at least one of the two mattresses 1 has a preset angle range of 0 to 22.5°. After adopting this setting, after the tilting airbag 12 is fully inflated, the angles formed by the two mattresses 1 are 30° and 22.5° respectively, thereby enabling the use of different body parts of the patient.

[0046] Further, such as Figure 2 and Figure 3 As shown, in order to better change the position of the spine, the two mattresses 1 have different lengths. The preset angle range of the longer mattress 1 is 0-22.5°, and the preset angle range of the shorter mattress 1 is 0-30°. After adopting this setting method, the longer mattress 1 can support the patient's lower limbs, part of the body and other parts, and the shorter mattress 1 can support the patient's head, neck and part of the body and other parts, so that the patient's spine can be flexed at the angle of the mattress 1, so that the spine at the surgical site is aligned.

[0047] Exemplarily, the two mattresses 1 are respectively the first mattress 1a and the second mattress 1b, the inflation angle of the first mattress 1a is 0-22.5°, the length of the first mattress 1a is 120cm, and the width of the first mattress 1a is 50cm; the inflation angle of the second mattress 1b is 0-30°, the length of the second mattress 1b is 80cm, and the width of the second mattress 1b is 50cm. During use, the patient's feet are placed on the first mattress 1a, and the patient's head is placed on the second mattress 1b. When the mattress 1 begins to inflate, the patient's spine can bend under the action of the angle of the mattress 1 until the upper end lifts the patient's limbs to a maximum of 30°, and the lower end lifts the patient's limbs to a maximum of 22.5°, so that the patient's spine is bent backward at a maximum angle of 52.5°, assisting the surgeon to complete the V-shaped spinal osteotomy and fusion fixation.

[0048] In some possible embodiments, the preset angle ranges of the two mattresses 1 are the same. After adopting this setting method, although the inclination angles of the two mattresses are the same, the needs of adjusting the patient's body position can also be met. Technical personnel in this field can also make a choice according to actual conditions.

[0049] Furthermore, in order to achieve auxiliary fixation of the patient, such as Figure 1 and Figure 3 As shown, a fixing belt 14 is provided on the mattress 1. When in use, the fixing belt 14 is used to fix the patient on the mattress 1 without displacement.

[0050] Exemplarily, the two mattresses 1 are respectively a first mattress 1a and a second mattress 1b. The first mattress 1a is provided with a fixing belt 14 for fixing the patient's pelvis to the mattress 1 without displacement, and the second mattress 1b is provided with a fixing belt 14 for fixing the patient's upper chest to the mattress 1 without displacement. After adopting this setting method, the patient's body position during the operation can be effectively protected and can be advantageously assisted in fixation.

[0051] Regarding the above-mentioned rotating member 2, as Figure 2 and Figure 3 As shown, the rotating member 2 includes a rotating shaft, a first connecting member and a second connecting member; the first connecting member and the second connecting member are both sleeved outside the rotating shaft, and the first connecting member and the second connecting member are both rotatably connected to the rotating shaft; the first connecting member is connected to any mattress 1, and the second connecting member is connected to the other mattress 1. When in use, the two mattresses 1 can form a rotatable and adjustable angle through the rotatable connection with the rotating member 2, thereby meeting more angle usage requirements.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
