Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an integrated device for detecting and removing intravascular thrombus and a method for using the same. Background Art

[0002] A blood clot is a small piece of blood formed on the surface of a peeling or repaired blood vessel in the cardiovascular system. A blood clot in the heart may cause myocardial infarction, while a blood clot in the brain may lead to cerebral infarction (stroke).

[0003] The above technologies still have some shortcomings in the process of thrombus detection and removal:

[0004] 1. The existing technology requires the use of corresponding equipment for thrombus detection and removal, so more equipment is used during the treatment process, which increases the cost of treatment, and the thrombus is often not removed in time after the detection is completed.

[0005] 2. During the thrombus cleaning process, blood and thrombus are generally placed directly in a special waste bag for disposal. If the properties of the thrombus need to be tested, it needs to be filtered separately, which undoubtedly increases the workload of medical staff.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Example 1

[0046] Reference Figure 1 - Figure 8 , an integrated device, which is used in the field of medical devices. The device integrates the functions of thrombus detection, positioning and removal, greatly improving the work efficiency of medical staff in dealing with intravascular thrombus. The device mainly includes the following parts: operating table 1, support arm 2, arc-shaped connecting arm 7, X-ray generator 8, L-shaped connecting rod 11, placement table 12, fixing table 13, negative pressure pump 15, fixing cylinder 16 and related removal structure, replacement structure and detection structure.

[0047] Reference Figure 1 - Figure 4 The operating table 1 is used for patients to lie flat and perform surgical operations. The support arm 2 is welded to one side of the operating table 1 to provide stable support. The arc-shaped connecting arm 7 is welded to one side of the support arm 2 and is located above the operating table 1. An X-ray generator 8 is fixed at its bottom end to emit X-rays for thrombus detection.

[0048] Reference Figure 1 - Figure 3The detection structure includes a fixed arm 3, which is fixed to one side of the support arm 2. The L-shaped rotating plate 4 is rotatably connected to the fixed arm 3, and the angle can be adjusted as needed. The supporting plate 5 is rotatably connected to the bottom of the L-shaped rotating plate 4, and the angle can also be adjusted. The display screen 6 is fixed to one side of the supporting plate 5 and is electrically connected to the X-ray generator 8, and is used to display the image irradiated by the X-ray, so as to quickly and accurately detect the position and size of the blood clot in the blood vessel.

[0049] Specifically, the patient lies flat on the operating table 1. The patient is irradiated with X-rays by the X-ray generator 8. The irradiated image is displayed on the display screen 6, and the medical staff can quickly and accurately detect the position and size of the blood clot in the blood vessel.

[0050] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 , the L-shaped connecting rod 11 is arranged on one side of the arc-shaped connecting arm 7. The placement table 12 is rotatably sleeved on the outer wall of the L-shaped connecting rod 11 and can be rotated to adjust the position. A plurality of fixed cylinders 16 are fixed on the top of the placement table 12, and a hollow tube 18 is sealed and slidably penetrated through the bottom end of each fixed cylinder 16. The top of the fixed table 13 is fixedly connected to the bottom end of the L-shaped connecting rod 11 to provide stable support for the equipment. The negative pressure pump 15 is fixed on the top of the fixed table 13 and cooperates with the placement table 12 to generate negative pressure to aspirate thrombus.

[0051] Reference Figure 4 , Figure 5 and Figure 8 The cleaning structure includes a plurality of support blocks 24 fixed to the inner wall of each fixed cylinder 16. The collecting cylinder 22 is placed in the fixed cylinder 16 to hold the sucked thrombus and blood, and the support blocks 24 support them. The sieve plate 23 is fixed in the collecting cylinder 22 to filter the sucked thrombus and blood. The closing cover 19 is threadedly connected to the top of the fixed cylinder 16 to close the fixed cylinder 16. The connecting pipe 20 is fixed and penetrates through the closing cover 19 and is connected to the suction catheter. The air inlet of the negative pressure pump 15 is fixed with an air inlet pipe 17, which cooperates with the hollow tube 18 to generate negative pressure to suck the thrombus.

[0052] Specifically, the suction catheter is connected to the joint tube 20. The negative pressure pump 15 is started to generate negative pressure through the cooperation of the air inlet pipe 17 and the hollow tube 18. The negative pressure makes the fixed tube 16 in a negative pressure state, and the thrombus is sucked into the collection tube 22 in the fixed tube 16. The sieve plate 23 filters the sucked thrombus and blood. After the removal is completed, the sealing cover 19 is opened and the collection tube 22 is taken out. The thrombus is tested or discarded as needed.

[0053] In this way, the integrated intravascular thrombus detection and removal device of this embodiment can greatly reduce the workload of medical personnel and improve the efficiency and accuracy of thrombus treatment.

[0054] Reference Figure 4 - Figure 7 The integrated device for detecting and removing intravascular thrombus also includes a replacement structure, which is arranged at the bottom of the placement table 12. The specific structure includes a groove 26, which is opened at the bottom of the placement table 12, and a sliding plate 27 is slidably connected in the groove 26. A plurality of magnet blocks 30 and a first spring 28 are fixed to the top of the sliding plate 27, and the top ends of the plurality of first springs 28 are fixedly connected to the top inner wall of the groove 26. A plurality of electromagnets 29 are also fixed to the top inner wall of the groove 26, and the electromagnets 29 cooperate with the magnet blocks 30 to generate magnetic attraction when power is turned on, thereby controlling the sliding plate 27 to move upward. The bottom end of the hollow tube 18 is fixedly passed through the sliding plate 27, so that the hollow tube 18 can move with the movement of the sliding plate 27.

[0055] Specifically, when the fixed cylinder 16 needs to be replaced, the electromagnet 29 is energized to generate magnetic attraction to the magnet block 30, driving the sliding plate 27 and the hollow tube 18 to move upward, so that the hollow tube 18 is released from the docking with the air intake pipe 17. At this time, the placement table 12 can be rotated to complete the replacement of the fixed cylinder 16. After the replacement is completed, the electromagnet 29 is powered off, and the sliding plate 27 moves downward under the elastic force of the first spring 28, so that the hollow tube 18 is docked with the air intake pipe 17 again, and the thrombus removal in other parts can be completed at this time. Through such a design, venous thrombus and arterial thrombus can be placed separately, which is convenient for thrombus detection at a later time.

[0056] Reference Figure 4 - Figure 7 Further, the replacement structure also includes an annular groove 31 provided on the outer wall of the L-shaped connecting rod 11, and the outer wall of the L-shaped connecting rod 11 is also provided with a plurality of inclined grooves 33, and the top ends of these inclined grooves 33 are all connected to the annular groove 31. The inner wall of the sliding plate 27 is provided with a plurality of sliding grooves 34, and a limiting rod 35 is slidably connected in the sliding groove 34. A second spring 36 is fixed to one end of the limiting rod 35 away from the L-shaped connecting rod 11, and one end of the second spring 36 is fixedly connected to one inner wall of the sliding groove 34. The limiting rod 35 is slidably matched with the inclined groove 33 and the annular groove 31.

[0057] Specifically, when the electromagnet 29 is energized and drives the sliding plate 27 and the hollow tube 18 to move upward, the sliding plate 27 also drives the limiting rod 35 to move upward into the annular groove 31, thereby releasing the brake between the sliding plate 27 and the L-shaped connecting rod 11, so that the placement table 12 can rotate freely to complete the replacement of the fixed cylinder 16. After the replacement is completed, the limiting rod 35 re-matches with the inclined groove 33 to brake the placement table 12 to prevent the placement table 12 from accidentally rotating when it is not necessary to rotate.

[0058] Reference Figure 4 , Figure 5 and Figure 7 In order to more accurately control the rotation and braking of the placement table 12, a plurality of pressure sensors 32 are fixedly embedded on the inner wall of one side of the annular groove 31. These pressure sensors 32 are located above the inclined groove 33 and cooperate with the limit rod 35. An indicator light 37 is also fixedly embedded on one side of the L-shaped connecting rod 11, and the indicator light 37 is electrically connected to the pressure sensor 32. When the limit rod 35 squeezes the pressure sensor 32, the pressure sensor 32 transmits a signal to the indicator light 37, and the indicator light 37 lights up. This can be used to determine the alignment of the limit rod 35 with the inclined groove 33 and the intake pipe 17 with the hollow pipe 18, so that the intake pipe 17 and the hollow pipe 18 can cooperate with each other after the electromagnet 29 is powered off in the later stage.

[0059] Reference Figure 3 A damping bearing 9 is fixedly mounted on the outer wall of the arc-shaped connecting arm 7 , a rotating ring 10 is sleeved on the outer wall of the damping bearing 9 , and one end of the L-shaped connecting rod 11 is fixedly connected to the rotating ring 10 .

[0060] In this way, the cooperation between the rotating ring 10 and the damping bearing 9 can enable the L-shaped connecting rod 11 to rotate to a suitable position, which is convenient for medical personnel to remove blood clots. At the same time, due to the characteristics of the damping bearing 9, the L-shaped connecting rod 11 can be prevented from rotating at will, ensuring the stability and accuracy of the operation.

[0061] Reference Figure 4 and Figure 8 Furthermore, a plurality of arc plates 14 are fixedly mounted on the top of the fixing platform 13, and the tops of the plurality of arc plates 14 are slidably connected to the bottom of the placing platform 12, so that the placing platform 12 can slide stably on the fixing platform 13. A sealing ring 21 is fixedly mounted on the top inner wall of the closing cover 19, which is used to increase the sealing between the closing cover 19 and the fixing cylinder 16 to prevent leakage of blood or thrombus during operation.

[0062] Reference Figure 8 In another part of the device, a limiting arc plate 25 is fixedly installed on the top of the support block 24 to limit the collection tube 22, ensuring that the position of the collection tube 22 in the device is stable and will not move during operation.

[0063] In summary, the integrated intravascular thrombus detection and removal device achieves effective detection and removal of thrombus through ingenious structural design, while ensuring the stability and accuracy of operation, and has high practical value and clinical significance.

[0064] Example 2

[0065] refer to Fig. 9 and Fig.10 , based on the improvement of Example 1: a sealing plate 38 located below the support block 24 is sealingly and slidably connected in the fixed cylinder 16, a rotating shaft 39 is rotatably connected in the fixed cylinder 16, and the rotating shaft 39 is located between the support block 24 and the sealing plate 38. A pull rope 41 is wound around the outer wall of the rotating shaft 39, and the bottom end of the pull rope 41 is fixedly connected to the top of the sealing plate 38. In this way, when the sealing plate 38 moves downward, the rotating shaft 39 will be driven to rotate through the pull rope 41.

[0066] refer to Fig. 9 and Fig.10 The outer wall of the rotating shaft 39 is fixedly sleeved with a plurality of cams 40 for striking the collecting tube 22, and two fixing plates 42, which are located on both sides of the two cams 40. The outer wall of the rotating shaft 39 is also sleeved with two torsion springs 43, the ends of the two torsion springs 43 close to each other are fixedly connected to the corresponding fixing plates 42, and the ends of the two torsion springs 43 far from each other are fixedly connected to the inner wall of the fixing tube 16. Such a design enables the torsion springs 43 to cooperate with the fixing plates 42 to drive the rotating shaft 39 to reset and rotate.

[0067] Specifically, in actual operation, when a thrombus enters the collection tube 22, the sealing plate 38 moves downward under the action of negative pressure, and the sealing plate 38 drives the rotating shaft 39 and the cam 40 to rotate through the pull rope 41. The cam 40 continuously knocks the collection tube 22, and such knocking can accelerate the separation of the thrombus from the blood and improve the removal efficiency of the device.

[0068] A method for using an integrated device for detecting and removing intravascular thrombi comprises the following steps:

[0069] S1. The patient lies on the operating table 1, a contrast agent is injected into the patient, and the patient is irradiated with X-rays by the X-ray generator 8, and the irradiated image is displayed on the display screen 6, which can quickly and accurately detect the position and size of the thrombus in the blood vessel, and the arc-shaped connecting arm 7 and the supporting plate 5 can be rotated as needed, so that medical staff can view it at different positions;

[0070] S2. When performing thrombus removal, the medical staff first inserts the suction catheter into the patient's body, and through the cooperation of the X-ray generator 8 and the display screen 6, the medical staff can accurately move the suction catheter to the thrombus position, and then connect the suction catheter with the joint tube 20;

[0071] S3. Suction is performed through the cooperation of the negative pressure pump 15, the air inlet pipe 17 and the hollow tube 18. The fixed tube 16 is in a negative pressure state. The joint tube 20 is connected to the suction catheter, and the thrombus can be sucked into the fixed tube 16. The thrombus falls into the collection tube 22. The sucked thrombus and blood can be filtered through the sieve plate 23. After the cleaning is completed, the sealing cover 19 can be opened to take out the collection tube 22. The thrombus can be detected and discarded as needed, which reduces the work intensity of medical staff. In addition, when the thrombus enters the collection tube 22, the sealing plate 38 moves downward under the action of negative pressure. The sealing plate 38 drives the rotating shaft 39 and the cam 40 to rotate through the pull rope 41. The cam 40 continuously knocks the collection tube 22 to accelerate the separation of the thrombus and the blood.

[0072] S4. When placing thrombus at other positions, the electromagnet 29 is energized, the electromagnet 29 generates magnetic attraction on the magnet block 30 and drives the sliding plate 27 and the hollow tube 18 to move upward, the hollow tube 18 is released from the docking with the air intake pipe 17, and the sliding plate 27 drives the limiting rod 35 to move upward into the annular groove 31, releasing the brake between the sliding plate 27 and the L-shaped connecting rod 11, and then the placement table 12 can be rotated to complete the replacement of the fixed cylinder 16, and when the limiting rod 35 touches the pressure sensor 32, the pressure sensor 32 detects the pressure signal and transmits the signal to the indicator light 37, the indicator light 37 lights up, at this time it can be determined that the hollow tube 18 corresponds to the air intake pipe 17, after the electromagnet 29 is powered off, the sliding plate 27 moves downward under the elastic force of the first spring 28, the hollow tube 18 docks with the air intake pipe 17, at this time the thrombus removal at other positions can be completed, the venous thrombus and the arterial thrombus can be placed separately, which is convenient for the later thrombus detection.

[0073] However, as is well known to those skilled in the art, the working principles and wiring methods of the pressure sensor 32, electromagnet 29, negative pressure pump 15, indicator light 37, display screen 6 and X-ray generator 8 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.
