[0036] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] The present invention provides the following preferred embodiments:

[0038] Example 1, as Figures 1-11 As shown, a cardiac compression device for easy operation in thoracic surgery includes a support plate 11, a compression mechanism, a limiting mechanism, two top plates 12, two lifting mechanisms, and two locking mechanisms.

[0039] Two clamping mechanisms are symmetrically arranged above two sides of the support plate 11, each lifting mechanism is installed on the top of a clamping mechanism, each top plate 12 is installed on the top end of a lifting mechanism, and the pressing mechanism is arranged between the two top plates 12;

[0040] The clamping mechanism is used to quickly install the lifting mechanism and the support plate 11, and also facilitates the disassembly of the support plate 11 from the device, and the lifting mechanism is used to adjust the height of the top plate 12 and the pressing mechanism, so as to adjust the initial position of the mounting mechanism according to the size of the patient's body;

[0041] The pressing mechanism comprises a housing 13, a pressing rod 20, a main pressing head 21, an auxiliary pressing head 22, an adjusting assembly, a moving assembly and a driving assembly, the housing 13 is fixed to one side of the two top plates 12 close to each other, the pressing rod 20 is slidingly arranged on the housing 13, the main pressing head 21 is fixed to the bottom end of the pressing rod 20, the auxiliary pressing head 22 is slidingly arranged on the outside of the pressing rod 20, the moving assembly is located between the auxiliary pressing head 22 and the pressing rod 20, the driving assembly is installed on the housing 13, and the adjusting assembly is located on one side of the driving assembly;

[0042] The driving assembly is used to drive the pressing rod 20 to lift, so as to realize the lifting of the main pressing head 21, so as to realize the pressing of the patient's heart, and the adjusting assembly is arranged to adjust the pressing depth, so as to adjust the stroke of the main pressing head 21 each time according to the requirement of the patient's pressing depth, which can not only avoid that the pressing depth is too small to meet the pressing requirement, but also avoid that the pressing is too deep to cause secondary damage to the patient, and the moving assembly can drive the auxiliary pressing head 22 to move, for children with small thoracic, a small main pressing head 21 can be used to press the patient's heart, so as to reduce the contact area and achieve precise control of the pressing position, and for adults, the auxiliary pressing head 22 can be moved to the outside of the main pressing head 21 by the moving assembly, so as to increase the area of the pressing head to achieve the effect of dispersing pressure, that is, by the main pressing head 21 and the auxiliary pressing head 22, the contact area can be adjusted according to the size to meet different requirements;

[0043] The limiting mechanism comprises a telescopic assembly and two limiting plates 47, the two limiting plates 47 are symmetrically arranged above the support plate 11, and the telescopic assembly is located between the two limiting plates 47 and the two lifting mechanisms, the telescopic assembly can drive the two limiting plates 47 to approach each other and fix the patient between the two limiting plates 47, so as to limit the patient, and ensure that the position of the patient does not shift after each heart pressing is completed, which is beneficial to precise pressing.

[0044] As Figures 5-6As shown, the drive assembly includes a turntable 18, a moving block 26, a hinge rod 19, a first motor 14, a fixed plate 15, a driving gear 16, and a driven gear 17. The driven gear 17 is rotatably disposed on the outside of the housing 13. The fixed plate 15 is fixed to one side of the housing 13. The driving gear 16 rotates on one side of the fixed plate 15 and meshes with the driven gear 17. The first motor 14 is mounted on the side of the fixed plate 15 away from the driving gear 16. The output end of the first motor 14 passes through the fixed plate 15 and is fixedly connected to the driving gear 16. The turntable 18 is positioned... Inside the housing 13, the turntable 18 and the driven gear 17 are coaxial and fixedly connected. That is, the rotation axis of the driven gear 17 passes through the housing 13 and is fixedly connected to the turntable 18. When the driven gear 17 rotates, the turntable 18 can rotate synchronously. The moving block 26 slides on the surface of the turntable 18 through the adjustment component. The adjustment component can adjust the position of the moving block 26, thereby adjusting the lifting depth of the main pressure head 21. One end of the hinge rod 19 is hinged to the moving block 26, and the other end of the hinge rod 19 is hinged to the top of the pressure rod 20.

[0045] When chest compressions are required, the patient is first placed above the support plate 11. The controller controls the first motor 14 to work. The first motor 14 can drive the drive gear 16 to rotate. Since the drive gear 16 and the driven gear 17 are meshed with each other, the rotation of the drive gear 16 can drive the driven gear 17 to rotate. The driven gear 17 can drive the turntable 18 to rotate synchronously. Under the action of the moving block 26 and the strip groove 29, the pressure rod 20 can be driven to move up and down at the bottom of the cover 13, thereby driving the main pressure head 21 to move up and down to achieve chest compressions for the patient.

[0046] It is important to note that when placing the support plate 11 under the patient's body, attention should be paid to the placement of the support plate 11 to ensure the accuracy of the pressure point.

[0047] like Figure 7 As shown, the adjustment assembly includes a fixed frame 23, a first lead screw 24, and a first micro motor 25. The fixed frame 23 is fixed to the surface of the turntable 18. The first lead screw 24 is located inside the fixed frame 23 and both ends are rotatably connected to the inner wall of the fixed frame 23. The first micro motor 25 is installed at one end of the fixed frame 23, and the output end of the first micro motor 25 is fixedly connected to one end of the first lead screw 24. The moving block 26 is installed on the outside of the first lead screw 24 and is threadedly engaged with the first lead screw 24. The moving block 26 slides inside the fixed frame 23.

[0048] When the pressing depth of the main pressing head 21 needs to be adjusted, the controller controls the first micro motor 25 to work, and the first micro motor 25 can drive the first lead screw 24 to rotate in the fixed frame 23. Since the first lead screw 24 and the moving block 26 are in threaded cooperation, and the moving block 26 can slide in the fixed frame 23, when the first lead screw 24 rotates, it can drive the moving block 26 to move in the fixed frame 23 along the length direction of the fixed frame 23, thereby indirectly adjusting the hinged position between the hinged rod 19 and the rotating disc 18, to adjust the distance of the reciprocating lifting of the pressing rod 20, thereby adjusting the pressing depth of the main pressing head 21.

[0049] In actual use, for adults, the pressing depth can be adjusted to about 5-6 cm, and for children, the pressing depth can be adjusted to about 3-4 cm, to meet different pressing depth requirements.

[0050] As shown in Figures 8-9 The moving assembly includes a second lead screw 27, a lifting block 28, a first bevel gear 31, a second bevel gear 32, a second micro motor 33, a fixed seat 34, and a plurality of moving rods 30. The middle part of the pressing rod 20 is provided with a cavity, and the lifting block 28 is slidingly arranged in the cavity. The surface of the pressing rod 20 is provided with a plurality of strip-shaped grooves 29, each of which is in communication with the cavity. Each moving rod 30 is slidingly arranged in one of the strip-shaped grooves 29. One end of each moving rod 30 is connected with the lifting block 28, and the other end of each moving rod 30 is connected with the auxiliary pressing head 22. The second lead screw 27 is located in the cavity and is rotatably connected with the pressing rod 20 at both ends. The second lead screw 27 penetrates through the lifting block 28 and is in threaded cooperation with the lifting block 28. The middle part of the lifting block 28 is provided with a threaded hole for the second lead screw 27 to penetrate through. The second bevel gear 32 is fixed to the surface of the second lead screw 27. The first bevel gear 31 is located on one side of the second bevel gear 32 and is in meshing cooperation with the second bevel gear 32. The fixed seat 34 is fixed to the outer wall of the pressing rod 20. The second micro motor 33 is installed on the fixed seat 34, and the output end of the second micro motor 33 is fixedly connected with the first bevel gear 31.

[0051] When the auxiliary pressing head 22 needs to be combined with the main pressing head 21, the controller controls the second micro motor 33 to work, and the second micro motor 33 can drive the first bevel gear 31 to rotate. Since the first bevel gear 31 and the second bevel gear 32 are in meshing cooperation with each other, when the first bevel gear 31 rotates, it can drive the second bevel gear 32 to rotate, thereby driving the second lead screw 27 to rotate in the pressing rod 20. When the second lead screw 27 rotates, it can drive the lifting block 28 to lift in the cavity of the pressing rod 20, and at the same time, the moving rods 30 can slide in the strip-shaped grooves 29, thereby achieving the lifting of the auxiliary pressing head 22. When the auxiliary pressing head 22 moves downward to the outside of the main pressing head 21, the combination of the main pressing head 21 and the auxiliary pressing head 22 is achieved.

[0052] For children with small thoracic, small main pressure head 21 can be directly used for heart compression, reducing the contact area to achieve precise control of the pressing position, and for adults, the auxiliary pressure head 22 can be moved to the outside of the main pressure head 21 by the moving assembly, increasing the area of the pressure head to achieve the effect of dispersing pressure, that is, through the main pressure head 21 and the auxiliary pressure head 22, the contact area can be adjusted according to the body size to meet different needs.

[0053] As shown in Figure 3 , Figure 10 Each lifting assembly includes a sleeve 35, an expansion plate 36, a connecting plate 37 and an electric push rod 38. The sleeve 35 is installed above the support plate 11 through a clamping mechanism. The expansion plate 36 is inserted into the top end of the sleeve 35 and is in sliding connection with the sleeve 35. The top end of the expansion plate 36 is fixedly connected with the top plate 12. The connecting plate 37 is fixed to the top end outer wall of the expansion plate 36. The electric push rod 38 is installed on one side of the sleeve 35. The output end of the electric push rod 38 is fixedly connected with the connecting plate 37.

[0054] When the initial position of the main pressure head 21 needs to be adjusted, the controller controls the electric push rod 38 to work. The electric push rod 38 can drive the expansion plate 36 to slide in the sleeve 35 through the connecting plate 37, so as to realize the adjustment of the position of the expansion plate 36. The expansion plate 36 can drive the top plate 12 and the pressing mechanism to move synchronously when moving, so as to drive the main pressure head 21 to move. The initial position of the main pressure head 21 can be adjusted according to the body size of the patient, so that the main pressure head 21 can initially fit the surface of the thoracic cavity of the patient, so as to improve the accuracy of the pressing depth.

[0055] It should be noted that the initial position here is the highest position in the lifting stroke of the main pressure head 21. When the adjusting assembly does not work, as the rotating disc 18 rotates, the articulated rod 19 can be located in the same straight line with the pressure rod 20, and the main pressure head 21 is located at the highest position in the lifting stroke of the main pressure head 21. At this time, the main pressure head 21 fits the thoracic cavity of the patient. With the rotation of the rotating disc 18, the main pressure head 21 can realize reciprocating lifting, that is, when the main pressure head 21 descends, it can perform heart compression on the patient.

[0056] As shown in Figures 1-3As shown, the telescopic assembly comprises a sliding piece, two cross plates 53, a plurality of movable blocks 50, a plurality of connecting rods 49 and a plurality of mounting plates 54, the two cross plates 53 are located on the lower sides of the housing 13, every two mounting plates 54 are fixed to the bottom ends of one cross plate 53, the other end of each mounting plate 54 is fixedly connected with the surface of one sleeve 35, the cross plate 53 can be fixed on the sleeve 35 through the mounting plate 54, thereby achieving the installation of the cross plate 53, it should be noted that the position of the cross plate 53 is relatively high and will not contact the patient's body, thus will not affect the heart compression process, every two movable blocks 50 are located on one side of one cross plate 53, and every two connecting rods 49 are fixed to one side of one limiting plate 47, and the top end of each connecting rod 49 is fixedly connected with one movable block 50.

[0058] When the patient position adjustment is completed, the second motor 55 is controlled to work through the controller, the second motor 55 can drive the bidirectional threaded rod 51 to rotate between the two side plates 56, since the two movable blocks 50 are threadedly connected with the bidirectional threaded rod 51 and the other two movable blocks 50 are slidably connected with the guide rod 52, when the bidirectional threaded rod 51 rotates, the two limiting plates 47 on the two sides can be driven to move through the movable blocks 50 and the connecting rods 49, when the two limiting plates 47 move towards each other, the limiting effect on the patient's body can be achieved, so that the patient position will not be displaced after each heart compression is completed, which is beneficial to realize precise compression.

[0063] When it is needed to detach the support plate 11 from the device, the two push rods 45 are pushed, so that the two push rods 45 can move in the inside of the guide rail 46 in the direction away from each other, at this time, the two sliding rods 43 can drive the two limiting blocks 42 to move in the direction away from each other, and the spring 44 is compressed, when the limiting block 42 moves out of the inside of the clamping groove formed by the connecting column 40 and the insertion block 41, it can contact the insertion block 41 to limit the insertion block 41, and the insertion block 41 can be pulled out from the inside of the mounting seat 39 to achieve the detachment;

[0064] When it is needed to connect the support plate 11 with the device together, the two side insertion blocks 41 are respectively inserted into the interiors of the two side two mounting seats 39, when the insertion block 41 moves, the first inclined surface on the insertion block 41 first contacts the second inclined surface on the limiting block 42, when the insertion block 41 moves downwards, the limiting block 42 can be extruded to move towards the direction close to the sliding rod 43, the spring 44 is compressed, with the continuous downward movement of the insertion block 41, when the clamping groove formed by the insertion block 41 and the connecting column 40 is moved to one side of the limiting block 42, the limiting block 42 can be reset and clamped into the interior of the clamping groove under the action of the spring 44, the limiting of the insertion block 41 is realized, and the quick assembly of the heart pressing device is realized;

[0065] Compared with the support plate 11 which cannot be disassembled in the prior art, when wearing, the patient needs to be dragged to make the patient wear into the device, which is time-consuming and laborious and inconvenient to operate, and the split support plate 11 is more convenient to wear the device on the patient's body, and has the effect of convenient operation.

[0066] The specific working process of the present application is as follows:

[0067] Firstly, the support plate 11 is placed at a suitable position below the patient's body, then the two side insertion blocks 41 are respectively inserted into the interiors of the two side two mounting seats 39, when the insertion block 41 moves, the first inclined surface on the insertion block 41 first contacts the second inclined surface on the limiting block 42, when the insertion block 41 moves downwards, the limiting block 42 can be extruded to move towards the direction close to the sliding rod 43, the spring 44 is compressed, with the continuous downward movement of the insertion block 41, when the clamping groove formed by the insertion block 41 and the connecting column 40 is moved to one side of the limiting block 42, the limiting block 42 can be reset and clamped into the interior of the clamping groove under the action of the spring 44, the limiting of the insertion block 41 is realized, and the quick assembly of the heart pressing device is realized;

[0068] Then the controller controls the electric push rod 38 to work, the electric push rod 38 can drive the telescopic plate 36 to slide in the interior of the sleeve 35 through the connecting plate 37, so that the position adjustment of the telescopic plate 36 is realized, the telescopic plate 36 can drive the top plate 12 and the pressing mechanism to move synchronously when moving, so that the main pressing head 21 can be moved, the initial position of the main pressing head 21 can be adjusted according to the body type of the patient, so that the main pressing head 21 can initially fit the surface of the chest cavity of the patient, so as to improve the accuracy of the pressing depth;

[0069] Meanwhile, the second motor 55 is controlled to work by the controller, and the second motor 55 can drive the bidirectional screw rod 51 to rotate between the two side plates 56. Since the two movable blocks 50 are in threaded connection with the bidirectional screw rod 51 and the other two movable blocks 50 are in sliding connection with the guide rods 52, when the bidirectional screw rod 51 rotates, the two limiting plates 47 on the two sides can be driven to move by the movable blocks 50 and the connecting rods 49. When the two limiting plates 47 move towards each other, the limiting effect on the patient's body can be achieved.

[0070] For children with small thoracic cavities, a small main pressing head 21 can be directly used to press the heart of the patient, so as to reduce the contact area and achieve accurate control of the pressing position. For adults, the second micro motor 33 can be controlled to work, and the second micro motor 33 can drive the first bevel gear 31 to rotate. Since the first bevel gear 31 and the second bevel gear 32 are in meshing connection with each other, when the first bevel gear 31 rotates, the second bevel gear 32 can be driven to rotate, so that the second lead screw 27 can be driven to rotate in the pressing rod 20. When the second lead screw 27 rotates, the lifting block 28 can be lifted in the cavity of the pressing rod 20, and the moving rod 30 can slide in the strip-shaped slot 29, so that the lifting of the auxiliary pressing head 22 can be achieved. When the auxiliary pressing head 22 moves downwards to the outside of the main pressing head 21, the main pressing head 21 and the auxiliary pressing head 22 can be combined, so that the area of the pressing head is increased to achieve the effect of dispersing pressure.

[0071] Then the controller controls the first motor 14 to work, and the first motor 14 can drive the driving gear 16 to rotate. Since the driving gear 16 and the driven gear 17 are in meshing connection with each other, when the driving gear 16 rotates, the driven gear 17 can be driven to rotate, and the driven gear 17 can drive the rotating disc 18 to rotate synchronously. Under the action of the moving block 26 and the strip-shaped slot 29, the pressing rod 20 can reciprocatingly lift at the bottom end of the cover 13, so that the main pressing head 21 can reciprocatingly lift, so as to achieve the heart pressing of the patient.

[0072] When it is necessary to adjust the pressing depth of the main pressing head 21, the controller controls the first micro motor 25 to work, and the first micro motor 25 can drive the first lead screw 24 to rotate in the fixed frame 23. Since the first lead screw 24 and the moving block 26 are in threaded connection, and the moving block 26 can slide in the fixed frame 23, when the first lead screw 24 rotates, the moving block 26 can move in the fixed frame 23 along the length direction of the fixed frame 23, so that the hinge position between the hinge rod 19 and the rotating disc 18 can be indirectly adjusted, the distance of the reciprocating lifting of the pressing rod 20 can be adjusted, and the pressing depth of the main pressing head 21 can be adjusted.
