Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments and equipment, and in particular to a multifunctional auxiliary device for interventional surgery and a method of using the same. Background Art

[0002] In the field of interventional surgery, the successful implementation of the surgery not only depends on the doctor's superb medical skills, but is also closely related to the various auxiliary devices used during the operation. With the continuous development of medical technology, the requirements for interventional surgery auxiliary devices are also increasing, aiming to provide more convenient, efficient and accurate support for the surgery to adapt to different surgical scenarios and doctors' operating habits, while ensuring the smooth progress of the surgery and reducing possible human errors.

[0003] Traditional interventional surgical auxiliary devices have certain limitations in many aspects. For example, in the setting of the tray used by the auxiliary device to place surgical instruments and other items, many devices adopt a fixed position. In actual surgery, this fixed position tray is often difficult to flexibly adjust according to different surgical scenarios and the individual operating habits of doctors. Since the interventional surgical operation process is complex and changeable, doctors may need to conveniently access and place instruments in different positions according to the progress of the operation. Fixed position trays cannot meet this demand, which may cause doctors to spend extra time and energy to adapt to the tray position during the operation, and may even affect the efficiency of the operation and the smoothness of the operation.

[0004] Furthermore, regarding the connection method between the tray and other parts of the auxiliary device, traditional methods mostly rely solely on mechanical buckles and other connection structures. Although this connection method can fix the tray to a certain extent, it has the problem of inconvenient operation. During the surgical preparation stage or when the tray needs to be replaced, medical staff need to spend a lot of time and energy to install and remove the buckles, and it is difficult to achieve automated control, which cannot meet the requirements of modern surgery for efficient and fast operation.

[0005] In addition, in terms of tray replacement, some existing auxiliary devices lack an efficient replacement mechanism. When a tray needs to be replaced, it often requires cumbersome steps, such as first removing the old tray and then installing the new tray through a series of complex operations. This process is not only time-consuming, but also prone to problems caused by improper manual operation, such as unstable tray installation, which in turn has an adverse effect on the normal operation of the operation.

[0006] Therefore, it is necessary to design a multifunctional auxiliary device for interventional surgery and a method of using the same to solve the above problems. Summary of the invention

[0012] Preferably, a controller is installed at the upper end of the placement table, a servo motor is installed at the upper end of the rectangular plate, and the output shaft end of the servo motor is fixedly connected to the vertical rod.

[0013] Preferably, a positioning assembly is provided on the placement table, and the positioning assembly includes two vertical plates arranged on the upper end of the placement table, the adjacent sides of the two vertical plates are fixedly connected with pneumatic rods, the telescopic ends of the two pneumatic rods are fixedly connected with push plates, and the upper end of the placement table is fixedly connected with multiple positioning blocks.

[0015] A method for using a multifunctional auxiliary device for interventional surgery, comprising the following steps:

[0016] S1: Place the pallet on the placement table so that it is located on the left side of the vertical plate and between the two positioning blocks; control the two pneumatic rods to stretch, so that the two push plates move relative to each other, and complete the placement and positioning of the pallet on the placement table;

[0017] S2: Turn on the power switch of the first electromagnet on the left side through the controller, so that the first electromagnet on the left side is energized, so that the insertion block enters the first insertion slot, and then the fixing rod passes through the through hole and enters the round hole, so as to complete the fixing of the tray and the insertion block;

[0018] S3: Using the characteristic that the pointer always points vertically downward under the action of gravity, when the device is tilted, the pointer contacts the two resistance plates, energizing the second electromagnet, thereby causing the first gear to drive the shaft to rotate at a greater angle, thereby quickly and stably adjusting the U-shaped frame and the device below to a horizontal state;

[0019] S4: When the pallet needs to be replaced, the new pallet is placed between the two positioning blocks on the right side of the placement table, and the old pallet is put down and taken away. Since the new pallet squeezes the corresponding second pressure sensor, the controller controls the first electromagnet on the left side to be energized to connect the new pallet;

[0020] S5: After the connection, the pallet is lifted by the crankshaft robot, and the new pallet is adjusted to the appropriate position by the servo motor.

[0021] The present invention has the following beneficial effects:

[0022] 1. Compared with the existing technology, the combination of crankshaft mechanical arm, rotating shaft, connecting block, U-shaped frame and other components can realize more flexible spatial position adjustment of the pressing block and the connecting components connected thereto. This adjustability enables the tray to be accurately positioned in a suitable position according to actual operation requirements during interventional surgery, making it convenient to place and take surgical instruments and other items. Compared with some auxiliary devices set in fixed positions, it can better adapt to different surgical scenarios and doctors' operating habits;

[0023] 2. Compared with the prior art, the connection assembly utilizes the first electromagnet, magnetic block, rectangular frame and related elastic connection structure in the vertical box to realize the connection and separation function between the vertical rod and the tray. Compared with the traditional connection method that simply relies on mechanical buckles, the operation is more convenient and a certain degree of automatic control can be achieved;

[0024] 3. Compared with the prior art, by setting two sets of connection components and servo motors, each time the pallet is replaced, it is only necessary to place the pallet to be replaced on the left side. When the crankshaft robot arm puts down the pallet, the new pallet can be connected, which greatly improves the efficiency of pallet replacement. At the same time, by setting the servo motor, no matter whether the replaced pallet is on the left or right side, it can be rotated to the appropriate direction for use;

[0025] 4. Compared with the prior art, the setting of the entire insertion assembly and the connection assembly is such that each time the tray is connected, the insertion block can be inserted into the insertion slot through the operation of a single first electromagnet, and at the same time the fixing rod passes through the through hole and enters the circular hole, so that the actions of the various components are coherent and coordinated. Compared with the components in the prior art that may operate independently, the accuracy and reliability of the connection are improved, a connection process with a high degree of automation is achieved, surgical preparation time is saved, and problems such as unstable connection caused by improper manual operation are reduced.

[0026] 5. Compared with the prior art, the horizontal adjustment component can realize convenient adjustment of the rotation angle of the crankshaft mechanical arm around the rotating shaft through the cooperation of the second electromagnet, the moving block, the first rack and other components in the control box with the first gear on the rotating shaft, thereby realizing the horizontal position adjustment of the entire device.

[0027] In summary, this multifunctional auxiliary device for interventional surgery has significant advantages over existing technologies and has consistent effects. First of all, through the coordination of crankshaft mechanical arms, rotating shafts and other components, it can flexibly adjust the position of the pressure block and the connecting component, accurately position the tray, and adapt well to various surgical scenarios and doctors' operating habits. Then, the connecting component uses the electromagnetic, elastic and other structures in the vertical box to realize the convenient connection and separation of the vertical rod and the tray, which is easy to operate and has automatic characteristics. Furthermore, the two sets of connecting components are equipped with servo motors, which are efficient and convenient when the tray is replaced. Then, the insertion component and the connecting component work together to complete the continuous action by running a single electromagnet, which improves the accuracy and reliability of the connection and saves preparation time. Finally, the horizontal adjustment component uses electromagnetic drive and rack and pinion transmission to achieve precise adjustment of the horizontal position of the device to adapt to the surgical environment and operating requirements.

The adjacent sides of the magnetic block 22 are elastically connected by the first spring 20. When the magnetic block 22 and the rectangular frame 21 are just disengaged, the multiple fixing rods 18 just enter into the through hole 16, thereby guiding the movement of the magnetic block 22. The lower end of the magnetic block 22 is fixedly connected to two thin rods 32, and the lower ends of the two thin rods 32 are commonly fixedly connected to a fixing plate 17, and the lower end of the fixing plate 17 is fixedly connected to multiple fixing rods 18. The tray 14 is provided with an insertion groove 42 on one side close to the pressing block 39, and the inner top of the insertion groove 42 is provided with multiple through holes 16. A connecting box 38 is fixedly connected to the pressing block 39, and an insertion block 40 is slidably connected in the connecting box 38. The upper end of the insertion block 40 is provided with multiple circular openings. After the insertion block 40 enters the insertion groove 42, the circular holes are aligned with the through holes 16.

[0036] Wherein, two insertion components are also included, the insertion component includes a rectangular frame 21 slidably connected in the vertical box 10, the magnetic block 22 and the adjacent sides of the rectangular frame 21 are attracted to each other, the lower end of the rectangular frame 21 is fixedly connected with a second rack 34, the inner wall of the vertical box 10 is fixedly connected with a limit block 33, the left and right inner walls of the vertical box 10 are rotatably connected with a cross bar 36, the cross bar 36 is provided with a second gear 35 matched with the second rack 34, the inner wall of the connecting box 38 on one side close to the pressing block 39 is rotatably connected with a threaded rod 41, the insertion block 40 is threadedly connected with the threaded rod 41, the threaded rod 41 and the cross bar 36 are connected through a transmission component 37, the transmission component 37 includes sprockets arranged on the threaded rod 41 and the cross bar 36, and the two sprockets are connected through chain transmission.

[0037] Among them, a first pressure sensor and two second pressure sensors are provided on the placement table 1. The first pressure sensor is located directly below the pressure block 39, and the two second pressure sensors are respectively located below the two trays 14. When the first pressure sensor is squeezed, when the second pressure sensor on one side is squeezed, the staff can only control the first electromagnet 19 on the same side to be energized through the controller 9. The controller 9 is installed at the upper end of the placement table 1, and the servo motor 8 is installed at the upper end of the rectangular plate 7. The end of the output shaft of the servo motor 8 is fixedly connected to the vertical rod, and the servo motor 8 can adjust the direction of the tray 14.

[0038] Among them, a positioning component is provided on the placement table 1, and the positioning component includes two vertical plates 11 arranged at the upper end of the placement table 1, and the adjacent sides of the two vertical plates 11 are fixedly connected with pneumatic rods 12, and the telescopic ends of the two pneumatic rods 12 are fixedly connected with push plates 13, and the upper end of the placement table 1 is fixedly connected with multiple positioning blocks 15.

[0039] Among them, it also includes a horizontal adjustment component, which includes a control box 23 arranged on the crankshaft mechanical arm 2, a first gear 28 is arranged on the rotating shaft 4, a second electromagnet 24 is arranged on the left inner wall of the control box 23, a moving block 26 is slidably connected in the control box 23, the second electromagnet 24 is elastically connected to the adjacent side of the moving block 26 through a second spring 25, and the right side of the moving block 26 is fixedly connected with a first rack 27 matched with the first gear 28, and the upper ends of the plurality of second electromagnets 24 are connected with wires, and the two resistor plates 31 on the left and the two resistor plates 31 on the right are connected to the positive and negative electrodes of the power supply. The connection method is opposite, so that when the U-shaped frame 3 deviates to the left, the second electromagnet 24 generates an attractive force on the moving block 26, so that the moving block 26 moves to the left. When the U-shaped frame 3 deviates to the right, the second electromagnet 24 generates a repulsive force on the moving block 26, so that the moving block 26 moves to the right. When the deflection angle is larger, the resistance value of the two resistor plates 31 connected to the circuit is smaller, so that the current passing through the second electromagnet 24 is larger, and the attraction of the second electromagnet 24 to the moving block 26 and the first rack 27 is larger, so that the first gear 28 drives the rotating shaft 4 to rotate at a larger angle.

[0040] A method for using a multifunctional auxiliary device for interventional surgery, comprising the following steps:

[0041] S1: Place the tray 14 on the placement table 1 so that it is located on the left side of the vertical plate 11 and between the two positioning blocks 15; control the two pneumatic rods 12 to stretch, so that the two push plates 13 move relative to each other, and complete the placement and positioning of the tray 14 on the placement table 1;

[0042] S2: Only the power switch of the first electromagnet 19 on the left side is turned on by the controller 9, so that the first electromagnet 19 on the left side is energized, so that the insertion block 40 enters the first insertion groove 42, and then the fixing rod 18 passes through the through hole 16 and enters the round hole, thereby completing the fixing of the tray 14 and the insertion block 40;

[0043] S3: Using the characteristic that the pointer 30 always points vertically downward under the action of gravity, when the device is tilted, the pointer 30 contacts the two resistor plates 31, so that the second electromagnet 24 is energized, and then the first gear 28 drives the rotating shaft 4 to rotate at a larger angle, thereby quickly and stably adjusting the U-shaped frame 3 and the device below to a horizontal state;

[0044] S4: When the tray 14 needs to be replaced, the new tray 14 is placed between the two positioning blocks 15 on the right side of the placement table 1, and the old tray 14 is put down and taken away. Since the new tray 14 presses the corresponding second pressure sensor, the first electromagnet 19 on the left side is energized through the controller 9 to connect the new tray 14;

[0045] S5: After the connection, the tray 14 is lifted by the crankshaft robot 2, and then the new tray 14 is adjusted to a suitable position by the servo motor 8.

[0046] The present invention can explain its functional principle through the following operation mode: place the tray 14 on the placement table 1 so that it is located on the right side of the vertical plate 11 and between the two positioning blocks 15, and then control the two pneumatic rods 12 to stretch so that the two push plates 13 move relatively, thereby completing the placement and positioning of the tray 14. After the tray 14 is placed, since the tray 14 presses the second pressure sensor on the left side and the pressure block 39 presses the first pressure sensor, the staff can only turn on the power switch on the first electromagnet 19 on the left side through the controller 9, so that the first electromagnet 19 on the left side is energized. After the first electromagnet 19 on the left side is energized, a repulsive force is generated on the rectangular frame 21 and the magnetic block 22, so that the rectangular frame 21 and the magnetic block 22 move downward. When the rectangular frame 21 moves downward, the second gear 35 and the cross bar 36 are driven to rotate through the second rack 34, and then the threaded rod 41 is driven to rotate through the transmission assembly 37, so that the insertion block 40 enters the insertion slot 42.

[0047] When the rectangular frame 21 moves down to contact with the limit block 33, the insertion block 40 just enters the specified position in the insertion slot 42, so that the circular hole is aligned with the through hole 16. Due to the repulsive force of the first electromagnet 19, the magnetic block 22 will continue to move down and separate from the rectangular frame 21 (when the magnetic block 22 and the rectangular frame 21 are just separated, the plurality of fixing rods 18 just enter into the through hole 16). As the magnetic block 22 continues to move down, the fixing rods 18 penetrate through the through hole 16 and enter into the circular hole, thereby fixing the tray 14 and the insertion block 40. At this time, the crankshaft robot 2 can be used to move the tray 14 to a suitable position.

[0048] During the movement, when the U-shaped frame 3 drives the entire device below to tilt, since the pointer 30 is always vertically downward under the action of gravity, the pointer 30 will contact the two resistor plates 31, so that the second electromagnet 24 is energized (when the deflection angle is larger, the resistance of the two resistor plates 31 connected to the circuit is smaller, so that the current passing through the second electromagnet 24 is larger, and the attraction of the second electromagnet 24 to the moving block 26 and the first rack 27 is larger, so that the first gear 28 drives the rotating shaft 4 to rotate at a larger angle), thereby adjusting the U-shaped frame 3 and the device below to a horizontal state.

[0049] After the adjustment, although the tray 14 is restored to a horizontal state, the pointer 30 is no longer in contact with the two resistor plates 31, and the second electromagnet 24 is powered off, the magnetism of the second electromagnet 24 will gradually disappear after the power is off, causing the U-shaped frame 3 to slowly rotate. Generally, the rotation of the U-shaped frame 3 caused by the movement of the crankshaft robot 2 or accidental collision has a swing period, and the setting of the second electromagnet 24 can quickly shorten this swing period, so that the tray 14 can quickly stabilize in a horizontal position.

[0050] It is worth mentioning that, since the two resistor plates 31 on the left and the two resistor plates 31 on the right are connected to the positive and negative poles of the power supply in opposite ways, when the U-shaped frame 3 deviates to the left, the second electromagnet 24 generates an attractive force on the moving block 26, so that the moving block 26 moves to the left. When the U-shaped frame 3 deviates to the right, the second electromagnet 24 generates a repulsive force on the moving block 26, so that the moving block 26 moves to the right, thereby ensuring that the tray 14 is always in a horizontal state when in use;

[0051] When the pallet 14 needs to be replaced, the pallet 14 is placed between the two positioning blocks 15 on the right side of the placement table 1, and then the old pallet 14 is put down by the crankshaft robot 2, and the current is disconnected through the controller 9. At this time, under the action of the second spring 25, the magnetic block 22 and the rectangular frame 21 are reset and contact is made to connect the pallet 14. At this time, the old pallet 14 can be taken away. Since the new pallet 14 on the left side squeezes the corresponding second pressure sensor at this time, the staff can only control the first electromagnet 19 on the left side to energize through the controller 9 to connect the new pallet 14. After the connection, the crankshaft robot 2 lifts the pallet 14, and then the servo motor 8 can be used to adjust the new pallet 14 to the position.

[0052] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A method for using a multifunctional auxiliary device for interventional surgery according to claims 1-7, characterized in that: The following steps are involved: S1: placing the tray (14) on the placement table (1) so that it is located on the left side of the vertical plate (11) and between the two positioning blocks (15); controlling the two pneumatic rods (12) to stretch so as to cause the two push plates (13) to move relative to each other, thereby completing the placement and positioning of the tray (14) on the placement table (1); S2: Turning on only the power switch of the first electromagnet (19) on the left side through the controller (9), energizing the first electromagnet (19) on the left side, causing the insertion block (40) to enter the first insertion slot (42), and then the fixing rod (18) passes through the through hole (16) and enters the circular hole, thereby completing the fixing of the tray (14) and the insertion block (40); S3: Utilizing the characteristic that the pointer (30) always points vertically downward under the action of gravity, when the device is tilted, the pointer (30) contacts the two resistor plates (31), energizing the second electromagnet (24), thereby causing the first gear (28) to drive the rotating shaft (4) to rotate at a greater angle, thereby quickly and stably adjusting the U-shaped frame (3) and the device below to a horizontal state; S4: When the tray (14) needs to be replaced, the new tray (14) is placed between the two positioning blocks (15) on the right side of the placement table (1), and the old tray (14) is put down and then taken away. Since the new tray (14) presses the corresponding second pressure sensor, the controller (9) controls the first electromagnet (19) on the left side to be energized, and the new tray (14) is connected; S5: After the connection, the tray (14) is lifted by the crankshaft mechanical arm (2), and then the new tray (14) is adjusted to a suitable position by the servo motor (8).
