Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a cardiac pacing regulating device in transcatheter aortic valve replacement. Background Art

[0002] With the development trend of an aging society in my country, the incidence of valvular degenerative diseases in the elderly is increasing, among which aortic stenosis has gradually become the most common valvular heart disease in this population. Statistics from developed countries show that about 1 / 3 of patients with severe aortic stenosis cannot undergo traditional surgical thoracotomy due to high surgical risks or contraindications. For these high-risk patients or those with contraindications to cardiac surgery, transcatheter aortic valve implantation can be used as an effective treatment. Transcatheter aortic valve implantation, or transcatheter aortic valve replacement, inserts an interventional catheter through the femoral artery to deliver the artificial heart valve to the aortic valve area to open, thereby completing the implantation of the artificial valve and restoring the valve function. While inserting a catheter into one femoral artery for surgery, a detection device needs to be inserted into the other femoral artery to facilitate real-time monitoring of the patient's physical condition. This operation does not require thoracotomy, so it is less traumatic and has a quick postoperative recovery. During the operation, the patient's position needs to be adjusted, the patient's chest needs to be relaxed, and the patient's legs need to be spread open to facilitate femoral artery puncture and to facilitate the delivery of the catheter into the heart. However, since the patient needs to be anesthetized before the operation, the patient cannot actively adjust his position after anesthesia, so medical staff need to adjust the patient's position to facilitate subsequent operations. However, since medical staff cannot maintain the patient's diastolic state well when adjusting the patient's position, the patient's diastolic state may change during the operation, increasing the risk of the operation.

[0003] Patent publication number: CN114983749A discloses a cardiac pacing adjustment device for transcatheter aortic valve replacement, including a load-bearing plate, the load-bearing plate is provided with a plurality of support columns, the load-bearing plate is connected to a plurality of elastic bands through a first adjustment component, the load-bearing plate is connected to a movable plate through a second adjustment component, the movable plate is connected to a lifting member through a third adjustment component, the lifting member is used to lift the patient's chest so that the patient's chest is away from the load-bearing plate, the patent manually inflates the lifting airbag, thereby lifting the patient's chest through the lifting airbag, because the airbag is easily weathered, oxidized and corroded, the airbag will be damaged, and the airbag will leak quickly after being inflated, losing the original function of the lifting airbag, the patent lacks a protective mechanism for the airbag, and cannot protect the airbag, resulting in a short service life of the patent.

DETAILED DESCRIPTION

[0023] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0024] A cardiac pacing and regulating device in transcatheter aortic valve replacement, such as Figure 1-Figure 8 As shown, it includes a base 1, an operating table 2, an electric push rod 4, a back pad 12 and a back-up mechanism. The operating table 2 is installed on the top of the base 1, and the electric push rod 4 is installed on the right side of the base 1. A through slot 6 is opened on the right side of the operating table 2, and the through slot 6 runs through the operating table 2. The back-up mechanism is connected in the through slot 6. The back pad 12 is slidably connected in the through slot 6. The back pad 12 is a rectangular parallelepiped, and the top of the back pad 12 is flush with the top of the operating table, so that the patient's back can rest comfortably on the back pad 12. The back-up mechanism includes a connecting plate 7, a fixing rod 8, a connecting block 9, a rotating rod 10 and a short Plate 11, a connecting plate 7 is fixedly connected to the push rod of the electric push rod 4, a fixing rod 8 is fixedly connected to the right side of the connecting plate 7, a connecting block 9 is fixedly connected to the top of the fixing rod 8, two rotating rods 10 are hinged on the left and right sides of the connecting block 9, the front and rear rotating rods 10 are hingedly connected to the operating table 2 through the short plate 11, and the sides of the rotating rods 10 that are away from each other are in contact with the bottom of the back pad 12, and the back-lifting mechanism is used to lift the back pad 12, and then lift the patient's back. The patient's back can be easily lifted up by the back-lifting mechanism, and there is no need for medical staff to manually relax the patient's chest. When performing transcatheter aortic valve replacement, the patient's chest needs to be relaxed. After the patient lies on the operating table 2 and is anesthetized, when the connecting plate 7 moves downward through the electric push rod 4, the connecting plate 7 moves downward to drive the fixing rod 8 to move downward, and the fixing rod 8 moves downward to drive the connecting block 9 to move downward. The connecting block 9 moves downward to make the rotating rods 10 rotate upward, and the corresponding short plates 11 rotate in the direction of approaching each other. The two rotating rods 10 rotate upward to lift the back pad 12. After the operation is completed, the rotating rod 10 is rotated downward by the electric push rod 4, so that the back pad 12 moves downward and resets. After the back pad 12 is reset, it is convenient for medical staff to move the patient off the operating table. The back-lifting mechanism can facilitate the catheter to pass through the subclavian artery during the operation, avoid the medical staff's inability to manually control the patient's posture well, and reduce the risk of the operation.

[0025] like Figure 2and Figure 3 As shown, a sliding ball 28 is fixedly connected to the side of the two rotating rods 10 that is away from each other. The diameter of the sliding ball 28 is greater than the height of the rotating rod 10, and a sliding groove is opened at the bottom of the back pad 12 to facilitate the sliding of the two sliding balls 28. When the rotating rod 10 rotates, the sliding ball 28 on the rotating rod 10 contacts the bottom of the back pad 12, and the sliding ball 28 slides along the sliding groove of the back pad 12, so that the back pad 12 moves upward. The sliding ball 28 can reduce the friction between the rotating rod 10 and the back pad 12, thereby reducing the wear of the back pad 12 and increasing the service life of the adjustment device.

[0026] like Figure 1 and Figure 4 As shown, it also includes a back opening plate 3 and a pull rod 5. The back opening plates 3 are hinged on the front and rear sides of the right part of the operating table 2. The ends of the two back opening plates 3 that are away from each other exceed the width of the operating table, so that the back opening plates 3 can support the patient's entire arm, which is convenient for subsequent back opening operations. The bottom of the back opening plates 3 is hinged with pull rods 5. The ends of the front and rear pull rods 5 that are away from the back plate 3 are hingedly connected to the push rod of the electric push rod 4, so that the back-lifting mechanism and the back opening plate 3 can cooperate with each other, and the connection between the connecting plate 7 and the pull rod 5 and the electric push rod 4 is on the same horizontal plane. After the patient is anesthetized, the patient's arms are fixed on the backboard 3, and then the two pull rods 5 are moved downward at the same time by the electric push rod 4. The downward movement of the pull rods 5 drives the backboard 3 to rotate downward, thereby moving the patient's arms downward, and finally relaxing the patient's chest. After the operation, the pull rods 5 are rotated upward by the electric push rod 4, so that the backboard 3 is rotated upward and reset, and then the patient's arms on the backboard 3 are released, and the patient is taken off the operating table 2. The patient's arms are moved downward by the backboard 3, which can further relax the patient's chest and stabilize the patient's posture.

[0027] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, a leg-pulling mechanism is also included. The middle part of the operating table 2 is connected to the leg-pulling mechanism. The leg-pulling mechanism moves the patient's legs by pulling the patient's thighs. The leg-pulling mechanism includes a U-shaped plate 13, a slider 14, a threaded rod 15, a guide rod 16, a handle 17, a fixed block 18, a vertical column 19 and a support plate 20. The front side of the operating table 2 is fixedly connected to the U-shaped plate 13, and the U-shaped opening of the U-shaped plate 13 is away from the operating table 2. The left and right sides of the U-shaped opening of the U-shaped plate 13 are slidably connected to the slider 14. The front side of the right slider 14 is threadedly connected to the threaded rod 15, the threaded rod 15 penetrates the right slider 14, and the threaded rod 15 is rotatably connected to the operating table 2. The end of the threaded rod 15 away from the operating table 2 is fixedly connected to the handle 17, and the outside of the handle 17 is fixedly connected to an anti-slip cover to prevent medical staff from wearing gloves. When the handle 17 is turned, it slips. A guide rod 16 is slidably connected to the front side of the left slider 14. The length of the guide rod 16 is the same as that of the threaded rod 15. The guide rod 16 passes through the left slider 14 and is fixedly connected to the operating table 2. A fixed block 18 is fixedly connected between the two sliders 14. A vertical column 19 is slidably connected inside the fixed block 18. The vertical column 19 passes through the fixed block 18. A support plate 20 is hinged on the top of the vertical column 19. When the patient's legs move, the support plate 20 can be rotated according to the angle of movement of the patient's legs, so that the top surface of the support plate 20 can maintain full contact with the patient's legs. The hinge between the vertical column 19 and the support plate 20 is wider than the U-shaped plate 13, which can prevent the vertical column 19 from sliding downward and causing the support plate 20 to move downward, thereby preventing the support plate 20 from moving downward and causing the patient's legs to be unable to contact the support plate 20.

[0028] Medical staff need to move and separate the patient's legs to facilitate femoral artery puncture. After fixing the patient's thigh on the support plate 20, rotate the threaded rod 15 through the handle 17 to make the slider 14 slide along the guide rod 16 away from the operating table 2, so that the patient's thigh on the support plate 20 can be moved to a suitable position, and then the femoral artery puncture operation is performed on the patient's thigh. After the operation is completed, reverse the threaded rod 15 through the handle 17 to make the slider 14 slide back along the guide rod 16, and then release the fixation of the patient's thigh on the support plate 20. The leg pulling mechanism can accurately move the patient's leg by rotating the threaded rod 15 after the patient is anesthetized, which is convenient for femoral artery puncture of the patient and convenient for suturing the surgical wound after the pacemaker is implanted. It is also applicable to patients of different weights.

[0029] like Figure 1 and Figure 5As shown, there are two leg-pulling mechanisms, and the leg-pulling mechanisms are independently arranged symmetrically in front and back. When the patient's legs are moved, the patient's legs are moved by two independent leg-pulling mechanisms, and the movement of each leg of the patient can be controlled separately. When a femoral artery puncture is performed on one leg and a catheter is inserted, a femoral artery puncture is performed on the other leg and a monitoring device is inserted to facilitate real-time monitoring of the patient's physical condition. The placement of each leg is controlled according to the femoral artery puncture, so that the adjustment device is more flexible and convenient when controlling the patient's legs.

[0030] like Figure 1 and Figure 7 As shown, it also includes a fixed seat 21, a first connecting rod 22 and a second connecting rod 23. The fixed seat 21 is fixedly connected to the upper left side of the base 1. The two fixed seats 21 are symmetrically arranged front and back, and the fixed seats 21 are located directly below the corresponding U-shaped plate 13. The top of the fixed seat 21 is hinged with a first connecting rod 22, and the side of the first connecting rod 22 away from the fixed seat 21 is hinged with a second connecting rod 23, and the side of the second connecting rod 23 away from the first connecting rod 22 is hinged to the corresponding vertical column 19. An angle is formed between the first connecting rod 22 and the second connecting rod 23, and the angle is an acute angle. The front and rear hinges of the first connecting rod 22 and the second connecting rod 23 are located on the side close to the handle 17. When separating the patient's legs, the threaded rod 15 is rotated by the handle 17 to move the tray away from the operating table 2, and the fixed block 18 drives the vertical column 19 away from the operating table 2. Due to the hinged relationship between the fixed seat 21, the first connecting rod 22 and the second connecting rod 23, when the vertical column 19 is away from the operating table 2, the first connecting rod 22 and the second connecting rod 23 will gradually become vertical, so that the vertical column 19 is moved away from the operating table 2 by the first connecting rod 22 and the second connecting rod 23 and moves upward along the fixed block 18, so that the patient's thigh can be lifted. After the operation, the threaded rod 15 is reversed by the handle 17 to make the tray 20 close to the operating table 2 and move downward to reset, so that the patient's legs can be moved upward while the patient's legs are separated, which is more convenient when performing femoral artery puncture on the patient's leg, and it is more convenient to suture the surgical wound after the pacemaker is implanted.

[0031] like Figure 1 and Figure 8As shown, the operating table 2 also includes a crossbar 24, a sliding plate 25 and a foot pad 26. The left side of the operating table 2 is fixedly connected with the crossbar 24 on both sides. The sliding plate 25 is slidably connected between the two crossbars 24. The sliding plate 25 is slidably connected to the operating table 2. Two foot pads 26 are slidably connected to the top of the sliding plate 25. The surface of the foot pad 26 is made of artificial fiber material, so that a large amount of friction can be generated between the foot pad 26 and the patient's foot, so that the foot pad 26 can move normally, and the foot pad 26 and the patient's foot are prevented from slipping, resulting in the sliding plate 25 and the foot pad 26 being unable to slide normally. When the patient lies on the operating table 2, the sliding plate 25 is moved so that the patient's feet are placed on the foot pad 26. When the leg pulling mechanism is used to move the patient's legs, the patient's feet will drive the sliding plate 25 close to the leg pulling mechanism. At the same time, when the patient's legs are separated, the feet will drive the foot pad 26 to slide on the sliding plate 25, thereby preventing the patient's feet from rubbing against the operating table to hinder the movement of the patient's legs, and improving the patient's body comfort.

[0032] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the device further includes elastic bands 27, and the back plate 3 and the support plate 20 are both fixedly connected with two elastic bands 27, which are used to fix the patient's limbs on the adjustment device. Before moving the patient's body position, the patient's limbs are fixed to the back plate 3 and the support plate 20 by the elastic bands 27, so as to facilitate the movement of the patient's limbs and prevent the patient's thighs from falling out of the support plate 20 during the movement, thereby ensuring that the adjustment mechanism can be used normally. When fixing the patient's limbs, the elastic bands 27 can avoid over-tightening the limbs and squeezing the patient's blood vessels, thereby affecting the operation.
