[0002] A thrombus is a small mass that forms on the surface of a blood vessel in the cardiovascular system at a point where blood has broken off or been repaired. Thrombosacs can cause serious harm to human health; for example, they can cause ischemia symptoms in the corresponding organs and severe symptoms such as limb necrosis. If a thrombus forms in a blood vessel, it can cause a blockage in blood flow. Thromboembolism can lead to a reduction in blood supply to organs or tissues, or the deposition of blood in certain organs or tissues, resulting in organ failure or dysfunction. Thromboembolic diseases are very common in clinical practice and seriously endanger human life and health.

[0003] Clinically, for cases of vascular embolism and thrombus accumulation, interventional surgery using thrombectomy devices is often employed to destroy and remove the thrombus. However, existing thrombectomy devices suffer from low thrombectomy efficiency, long operation time, and unsatisfactory thrombectomy results.

[0037] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0038] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0040] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0042] Reference Figures 1a-4 As shown, according to one embodiment of this application, a thrombus removal device is provided. The thrombus removal device includes a drive mechanism 1 and a transmission assembly 2, the transmission assembly 2 being connected to the drive mechanism 1;

[0043] It also includes a first guide wire 31 and a second guide wire 32, the proximal ends of the first guide wire 31 and the second guide wire 32 are both connected to the transmission assembly 2; the driving mechanism 1 drives the first guide wire 31 and the second guide wire 32 to rotate through the transmission assembly 2.

[0044] When a thrombus removal device provided in this application requires surgical treatment due to thrombus accumulation and embolism, the first guidewire 31 and the second guidewire 32 of the thrombus removal device are inserted into the patient's blood vessel and placed at the lesion. Then, the drive mechanism 1 drives the transmission assembly 2 to rotate the first guidewire 31 and the second guidewire 32, and the distal ends of the first guidewire 31 and the second guidewire 32 destroy and remove the thrombus.

[0045] When performing thrombectomy using the thrombectomy device provided in this application embodiment, the two guidewires (first guidewire 31 and second guidewire 32) rotate together to break down and remove the thrombus. This improves the efficiency of thrombectomy and breaks the thrombus into smaller pieces, facilitating subsequent aspiration. Therefore, using the thrombectomy device provided in this application embodiment helps shorten the operation time and reduce patient suffering.

[0046] Optionally, the thrombus removal device further includes a connecting protective sleeve 33; the connecting protective sleeve 33 is sleeved on the distal ends of the first guidewire 31 and the second guidewire 32, and the connecting protective sleeve 33 is made of silicone material, which can prevent the distal ends of the first guidewire 31 and the second guidewire 32 from making hard contact with the blood vessel wall and damaging the human blood vessel.

[0047] The connecting protective sleeve 33 can be configured in two structures. The first structure is as follows: (Refer to...) Figure 1aAs shown, the connecting protective sleeve 33 includes a first sub-sleeve 331 and a second sub-sleeve 332. The first sub-sleeve 331 is fitted onto the distal end of the first guide wire 31, and the second sub-sleeve 332 is fitted onto the distal end of the second guide wire 32. In this structure, the first guide wire 31 and the second guide wire 32 each have an independent connecting protective sleeve; the first guide wire 31 and the first sub-sleeve 331, as well as the second guide wire 32 and the second sub-sleeve 332, can be fixedly connected, that is, the first sub-sleeve 331 rotates synchronously with the first guide wire 31, and the second sub-sleeve 332 rotates synchronously with the second guide wire 32. Alternatively, the first guidewire 31 and the first sub-sleeve 331, as well as the second guidewire 32 and the second sub-sleeve 332, can be in the form of a sliding connection, that is, the distal end of the first guidewire 31 rotates within the first sub-sleeve 331, and the first sub-sleeve 331 does not rotate with the first guidewire 31; the distal end of the second guidewire 32 rotates within the second sub-sleeve 332, and the second sub-sleeve 332 does not rotate with the second guidewire 32.

[0048] Second structure: Reference Figures 1b-1d As shown, the connecting protective sleeve 33 is provided with a first chamber 301 and a second chamber 302 spaced apart. The distal end of the first guide wire 31 is sleeved in the first chamber 301, and the distal end of the second guide wire 32 is sleeved in the second chamber 302. In this structure, the first guide wire 31 and the second guide wire 32 share the same connecting protective sleeve; the first guide wire 31 and the second guide wire 32 are slidably connected to the connecting protective sleeve 33, that is, the distal end of the first guide wire 31 rotates in the first chamber 301, and the distal end of the second guide wire 32 rotates in the second chamber 302, and the connecting protective sleeve 33 does not rotate with the first guide wire 31 and the second guide wire 32.

[0049] Reference Figure 1a , Figure 1b , Figure 3 As shown, in one embodiment, the thrombus removal device further includes a first catheter 41, a second catheter 42, and a regulating valve 5. The first catheter 41 is sleeved outside the first guidewire 31, and a first cavity is formed between the first catheter 41 and the first guidewire 31. The distal end of the first catheter 41 has a first drug outlet 410 communicating with the first cavity. The second catheter 42 is sleeved outside the second guidewire 32, and a second cavity is formed between the second catheter 42 and the second guidewire 32. The distal end of the second catheter 42 has a second drug outlet 420 communicating with the second cavity.

[0050] The regulating valve 5 is connected to the proximal ends of the first conduit 41 and the second conduit 42, and the regulating valve 5 is in communication with the first cavity and the second cavity.

[0051] In this specific example, the regulating valve 5 can be a three-way valve, with one port connected to the first and second cavities via a pipe; alternatively, the first and second cavities can also be interconnected, facilitating simultaneous connection of both cavities to the regulating valve 5. Thrombolytic drugs and other medications prescribed by the physician during the procedure can be injected through the other two ports of the regulating valve 5. The medication is simultaneously released from the first and second outlet ports 410 and 420 to the designated location. The two outlet ports (first outlet port 410 and second outlet port 420) improve the speed and efficiency of drug injection and shorten the injection time.

[0052] Reference Figure 1a , Figure 1b , Figure 3 As shown, in one embodiment, the regulating valve 5 can move the first conduit 41 and the second conduit 42 so that the first conduit 41 moves closer to or further away from the distal end of the first guidewire 31, and the second conduit 42 moves closer to or further away from the distal end of the second guidewire 32.

[0053] In this specific example, the regulating valve 5 can also move the first catheter 41 and the second catheter 42. When the first guidewire 31 and the second guidewire 32 initially enter the patient's blood vessel but have not yet reached the lesion, the distal end of the first guidewire 31 is wrapped by the first catheter 41, and the distal end of the second guidewire 32 is wrapped by the second catheter 42. This avoids unnecessary damage to the patient's blood vessel when the first guidewire 31 and the second guidewire 32 enter the patient's blood vessel. When the first guidewire 31 and the second guidewire 32 reach the lesion, the regulating valve 5 moves the first catheter 41 and the second catheter 42, so that the distal ends of the first guidewire 31 and the second guidewire 32 are fully exposed, allowing the first guidewire 31 and the second guidewire 32 to destroy and remove the thrombus. Optionally, the distal ends of the first guidewire 31 and the second guidewire 32 are corrugated, allowing for rapid rotation in the middle segment of the thrombus and the segment of the blood vessel wall, thereby improving the effect of destroying and removing the thrombus.

[0054] Reference Figure 4 As shown, in one embodiment, the drive mechanism 1 includes a control component 11 and a drive motor 12, the control component 11 being electrically connected to the drive motor 12, and the drive motor 12 being connected to the transmission component 2.

[0055] In this specific example, the control component 11 controls the start and stop of the drive motor 12, and can also control parameters such as the speed and rotation angle of the drive motor 12. The drive motor 12 controls the rotation of the first guide wire 31 and the second guide wire 32 through the transmission component 2.

[0056] Reference Figure 4As shown, in one embodiment, the drive motor 12 is equipped with a position sensor.

[0057] In this specific example, the position sensor in the drive motor 12 can provide feedback on the resistance of the first guidewire 31 and the second guidewire 32 in the blood vessel. When the resistance encountered by the first guidewire 31 and the second guidewire 32 reaches a preset resistance threshold, the drive motor 12 transmits the resistance signal fed back by the position sensor to the control component 11. Then, the control component 11 adjusts the output feedback signal to increase the current supplied to the drive motor 12, thereby increasing the output torque of the drive motor 12 and preventing the first guidewire 31 and the second guidewire 32 from rotating poorly and failing to break up the thrombus.

[0058] Reference Figure 4 As shown, in one embodiment, the control component 11 includes a rechargeable battery 111 and a drive control board 112, both of which are electrically connected to the drive control board 112; the drive control board 112 is provided with control buttons 110.

[0059] In this specific example, the rechargeable battery 111 in the control component 11 provides power to the drive motor 12, and the rechargeable battery 111 can be charged through the charging port 1110. Furthermore, the control circuit in the drive control board 112 can be configured for dual-power control. When the rechargeable battery 111 malfunctions or experiences low voltage, preventing normal power supply, an external power source can be connected to ensure the control circuit operates normally, guaranteeing the normal operation of the thrombus removal device. Additionally, the drive control board 112 can be equipped with a power indicator light 1121 to display battery level.

[0060] The drive motor 12 can achieve two rotation modes through magnetic field orientation control: a 360° rotation mode and a small-angle rotation mode, such as 70°. The 360° rotation mode is suitable for clearing large areas of thrombus, while the small-angle rotation mode is suitable for clearing small areas of thrombus. The control buttons 110 include a start / stop button 1101 for controlling the start and stop of the drive motor 12, and a mode button 1102 for controlling the rotation mode of the drive motor 12.

[0061] Reference Figure 2 As shown, in one embodiment, the transmission assembly 2 includes a driving gear 21, a first driven gear 22, and a second driven gear 23. The driving gear 21 is connected to the drive mechanism 1, and both the driving gear 21 and the second driven gear 23 mesh with the first driven gear 22. The first driven gear 22 is connected to the proximal end of the first guide wire 31, and the second driven gear 23 is connected to the proximal end of the second guide wire 32.

[0062] In this specific example, the transmission assembly 2 includes a driving gear 21, a first driven gear 22, and a second driven gear 23. The driving gear 21 is connected to the drive mechanism 1, specifically to the output shaft of the drive motor 12. As the output shaft of the drive motor 12 rotates, it drives the driving gear 21 to rotate. The driving gear 21 then drives the first driven gear 22, which in turn drives the second driven gear 23 to rotate. The first driven gear 22 and the second driven gear 23 rotate in opposite directions, allowing the first guide wire 31 and the second guide wire 32 to rotate bidirectionally in opposite directions. This is more conducive to breaking up the thrombus into smaller pieces and further improving the thrombus removal efficiency.

[0063] Reference Figure 3 As shown, in one embodiment, the transmission assembly 2 further includes a first braking element 24 and a second braking element 25. The proximal end of the first guide wire 31 is connected to the first braking element 24, and the first braking element 24 has an engaged state and a disengaged state with the first driven gear 22. The proximal end of the second guide wire 32 is connected to the second braking element 25, and the second braking element 25 has an engaged state and a disengaged state with the second driven gear 23.

[0064] In this specific example, by controlling the switching between the first braking element 24 and the first driven gear 22 in the engaged and disengaged states, and by controlling the switching between the second braking element 25 and the second driven gear 23 in the engaged and disengaged states, it is possible to select whether the first guidewire 31 and the second guidewire 32 rotate together simultaneously, or the first guidewire 31 rotates alone, or the second guidewire 32 rotates alone; thereby enabling flexible selection of the rotation mode of the two guidewires according to the specific surgical situation.

[0065] Reference Figure 3 As shown, in one embodiment, the thrombus removal device includes a first housing 6; the first braking member 24 includes a first connecting seat 241 and a first sliding block 242, the first connecting seat 241 is mounted on the first sliding block 242, the proximal end of the first guide wire 31 is connected to the first connecting seat 241, the first connecting seat 241 is disposed inside the first housing 6, the first sliding block 242 is partially exposed outside the first housing 6, and the first sliding block 242 can drive the first connecting seat 241 to move under the action of external force, so that the first connecting seat 241 and the first driven gear 22 can be engaged or separated from each other;

[0066] The second braking component 25 includes a second connecting seat 251 and a second sliding block 252. The second connecting seat 251 is mounted on the second sliding block 252. The proximal end of the second guide wire 32 is connected to the second connecting seat 251. The second connecting seat 251 is disposed inside the first housing 6. The second sliding block 252 is partially exposed outside the first housing 6. The second sliding block 252 can drive the second connecting seat 251 to move under the action of external force, so that the second connecting seat 251 and the second driven gear 23 can engage or disengage from each other.

[0067] In this specific example, the portion of the first sliding block 242 exposed outside the first housing 6 can be used as a sliding switch. By applying external force to the sliding switch, the operator can move the first connecting seat 241 via the first sliding block 242, thereby controlling the engagement or disengagement of the first connecting seat 241 and the first driven gear 22. When the first connecting seat 241 and the first driven gear 22 are engaged, the drive motor 12 drives the first driven gear 22 to rotate via the drive gear 21, and the first driven gear 22 in turn drives the first connecting seat 241 and the first guide wire 31 to rotate. When the first connecting seat 241 and the first driven gear 22 are disengaged, the rotation of the drive motor 12 cannot drive the first guide wire 31 to rotate.

[0068] Similarly, the portion of the second sliding block 252 exposed in the first housing 6 can be used as a sliding switch. By applying external force to the sliding switch, the operator can move the second connecting seat 251 via the second sliding block 252, thereby controlling the engagement or disengagement of the second connecting seat 251 and the second driven gear 23. When the second connecting seat 251 and the second driven gear 23 are engaged, the drive motor 12 drives the second driven gear 23 to rotate via the drive gear 21, and the second driven gear 23 in turn drives the second connecting seat 251 and the second guide wire 32 to rotate. When the second connecting seat 251 and the second driven gear 23 are disengaged, the rotation of the drive motor 12 cannot drive the second guide wire 32 to rotate.

[0069] Reference Figure 1a , Figure 1b , Figure 3 , Figure 4 As shown, in one embodiment, the thrombus removal device includes a first housing 6 and a second housing 7, the drive mechanism 1 is mounted on the second housing 7, and the transmission assembly 2, the first guide wire 31 and the second guide wire 32 are mounted on the first housing 6; the first housing 6 and the second housing 7 are detachably connected.

[0070] In this specific example, the drive mechanism 1, including the drive motor 12, rechargeable battery 111, and drive control board 112, is installed inside the second housing 7. The second housing 7 is a waterproof and dustproof fully sealed structure that can be reused multiple times. The first housing 6, which contains the first guide wire 31 and the second guide wire 32, can be used as a disposable consumable depending on the usage.

[0071] The first housing 6 and the second housing 7 are designed to be detachably connected. This avoids wasting the second housing 7 and the drive mechanism 1 installed inside it when the first housing 6 is thrown, thereby improving the utilization rate of the drive mechanism 1, reducing costs, and saving energy and protecting the environment.

[0072] Optionally, the first housing 6 and the second housing 7 are connected by a snap-fit ​​connection. When connecting, firstly, the output shaft of the drive motor 12 installed in the second housing 7 is positioned and connected with the drive gear 21 installed in the first housing 6. Then, the snap-fit ​​structure of the first housing 6 and the second housing 7 that match each other is snapped together. The whole assembly process is simple and convenient.

[0073] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
