Technical Field

[0001] The present invention relates to the field of thrombus treatment, and particularly to a thrombus treatment and care device for thrombus treatment. Background Art

[0002] With the development of society, people's lifestyles have changed greatly. The long-term sedentary office mode, the popularity of high-calorie and high-fat diets, and the prevalence of bad habits such as smoking and excessive drinking have made the risk factors for thrombus formation spread widely among the population. Coupled with the aggravation of population aging, the physical functions of the elderly decline, blood vessel elasticity decreases, and blood viscosity increases, further promoting the sharp rise in the incidence of thrombus.

[0003] When treating thrombus, interventional treatment techniques are mostly used for thrombus treatment. Interventional treatment techniques take effect faster than drug treatment, can quickly remove thrombus to avoid other complications caused by thrombus blockage, and also cause less trauma to patients than surgical operations. At the same time, patients recover faster and the recurrence rate is reduced. However, the existing interventional treatment equipment is not perfect enough. For example, when cleaning thrombus, the remaining small thrombus cannot be completely cleaned up and will flow along with the blood, resulting in symptoms such as pulmonary embolism.

[0039] The first embodiment

[0040] Please refer to Figure 1 and Figure 2 . A thrombus treatment and care device for thrombus treatment, comprising: a casing 1;

[0041] A negative pressure extraction chamber 3, the negative pressure extraction chamber 3 is arranged inside the casing 1;

[0042] A cutting net 6, the cutting net 6 is fixedly installed on one side of the negative pressure extraction chamber 3;

[0043] A sealing cover 16, the sealing cover 16 is fixedly installed on one side of the axis of the cutting net 6;

[0044] A telescopic tube 8, the starting end of the telescopic tube 8 is fixedly installed on one side of the sealing cover 16, and the telescopic tube 8 is provided with multiple sections;

[0045] A first sealing ring 91, the inner wall of the first sealing ring 91 is fixedly installed with the end of the telescopic tube 8;

[0046] A second sealing ring 92, the first sealing ring 91 is fixedly connected to the second sealing ring 92 through a balloon 10, the balloon 10 is circular and fixedly connected to the outer walls of the first sealing ring 91 and the second sealing ring 92;

[0047] A piston cylinder 11, the piston cylinder 11 is slidably connected inside the first sealing ring 91 and the second sealing ring 92;

[0048] A disc 17, the disc 17 is fixedly installed on one side of the piston cylinder 11;

[0049] The drive box 12 is fixedly installed on one side of the second sealing ring 92. The disc 17 is arranged inside the drive box 12 and is slidably connected to the inner wall of the drive box 12. The size of the opening on the left side of the drive box 12 is adapted to the piston cylinder 11;

[0050] The electric push rod 13 is fixedly installed on the inner wall of the drive box 12, and the output end of the electric push rod 13 is fixedly connected to one side of the disc 17.

[0051] During actual use, the end of the device outside the human body is the proximal end, and the end located at the thrombus is the distal end;

[0052] The telescopic tube 8 to the drive box 12 are all installed in a sealed manner;

[0053] There is liquid inside the telescopic tube 8;

[0054] A limiting ring is arranged on the inner wall of the catheter 1, so that the catheter 1 can be recovered after the device is pushed out during recovery;

[0055] The balloon 10 is set to be soft and telescopic, and will not cause damage to the inner wall of the blood vessel.

[0056] The working principle of a thrombus treatment and care device for thrombus treatment provided by the present invention is as follows:

[0057] First, after providing a detailed blood vessel image through CT detection outside the patient's body, after obtaining the position of the blood vessel where the thrombus is generated, the device is placed upstream and then reaches the lesion area, that is, the area where the thrombus is generated in the blood vessel.

[0058] Then, after reaching the lesion area, through the pipeline connected to the negative pressure extraction cavity 3, the doctor pushes the negative pressure extraction cavity 3 out of the sleeve 1 outside the patient's body and stops after the drive box 12 passes through the thrombus.

[0059] Then, start the electric push rod 13 to drive the disc 17 to slide inside the drive box 12. At the same time, the disc 17 also drives the piston cylinder 11 to move towards the distal end. At this time, the liquid inside the telescopic tube 8 drives the telescopic tube 8 to contract towards the distal end. The cutting net 6 fixedly installed on one side of the sealing cover 16 also moves towards the distal end. At the same time, the liquid fills the balloon 10. The balloon 10 has a soft shell and will not cause damage to the inner wall of the blood vessel. After filling the blood vessel, the thrombus between the balloon 10 and the cutting net 6 is squeezed and cut into several small pieces by multiple groups of thin metal wires on the cutting net 10. After the balloon 10 fills the blood vessel, the small thrombus will not continue to flow into other blood vessels of the patient.

[0060] Then, after cutting, several small blood clots fall into the interior of the negative pressure extraction chamber 3, and the blood clots are extracted outside the patient's body through the connected hose.

[0061] Finally, after the blood clots are cleared, the electric push rod 13 resets, the balloon 10 contracts and resets, the cutting net 6 returns to its original position, and the device is taken out of the patient's body by the doctor pulling back the hose externally.

[0062] Compared with the related art, a thrombus treatment and care device for thrombus treatment provided by the present invention has the following beneficial effects:

[0063] The cutting net 6 is driven by the electric push rod 13 to move to squeeze and cut the thrombus. The doctor recovers the thrombus externally through the hose connected to the negative pressure extraction chamber 3. The balloon 10 is provided to fill the blood vessel when clearing the thrombus, avoiding the secondary injury caused by the small thrombus blocks flowing into other parts of the patient and the failure of thrombus clearance caused by thrombus recurrence. The extremely small wound enables the patient to recover faster, simplifies the wound cleaning, and reduces the wound infection rate at the same time.

[0064] Second Embodiment

[0065] Please refer to Figures 3 - 5 , based on a thrombus treatment and care device for thrombus treatment provided in the first embodiment of the present application, a second embodiment of the present application proposes another thrombus treatment and care device for thrombus treatment. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0066] Specifically, the difference of a thrombus treatment and care device for thrombus treatment provided in the second embodiment of the present application is that a cross fixing plate 2 is fixedly installed inside the negative pressure extraction chamber 3.

[0067] A medicine injection chamber 4 is fixedly installed on one side of the cross fixing plate 2, and the medicine injection chamber 4 is provided with an opening facing the cutting net 6.

[0068] The inner wall of the medicine injection cavity 4 is fixedly installed with a medicine injection mechanism 5. The medicine injection mechanism 5 includes spring latches 501. The two spring latches 501 are symmetrically and fixedly connected to the inner wall of the medicine injection cavity 4 through a rotating bracket. A tension spring 502 is arranged between the two spring latches 501. Both ends of the tension spring 502 are fixedly connected to the inner wall of the medicine injection cavity 4 through a connecting rod. A sealing ring 504 is fixedly installed on the inner wall of the medicine injection cavity 4. A diversion shell 505 is fixedly installed on one side of the sealing ring 504. An opening is arranged on the side of the diversion shell 505 close to the tension spring 502. A push rod 503 is arranged inside the sealing ring 504. One end of the push rod 503 contacts the spring latch 501, and the other end of the push rod 503 is fixedly installed on the surface of one of the annular metal wires of the cutting net 6. The push rod 503 is fixedly installed on the inner wall of the medicine injection cavity 4 through a sliding bracket.

[0069] A check valve 19 is fixedly installed at the opening of the diversion shell 505.

[0070] During actual use, the push rods 503 at both ends push the two spring latches 501 to open;

[0071] When the tension spring 501 contracts the medicine injection cavity 4, there is a relatively large force to make the medicine spray out through the check valve 19;

[0072] Thrombolytic drugs are arranged inside the medicine injection cavity 4 and the thrombolytic drugs are liquid;

[0073] The left side of the spring latch 501 of the medicine injection cavity 4 is a hard shell, and installing the spring latch 501 does not cause deformation. The right side is a soft shell for the tension spring 502 to pull. The medicine injection cavity 4 on the right side of the sealing ring 504 is a hard shell;

[0074] The position where the push rod 503 passes through the sealing ring 504 is sealed.

[0075] The working principle of a thrombus treatment and care device for thrombus treatment provided by this embodiment is as follows:

[0076] First, drive the device to work through the electric push rod 13 in Embodiment 1. At this time, when the cutting net 6 cuts the thrombus, when encountering a thrombus with a long formation time and large hardness, the metal wires on the cutting net 6 will deform.

[0077] Then, the annular metal wire on the cutting net 6 fixedly installs the push rod 503. The push rod 503 is limited by the sliding bracket. When receiving the driving force of the deformation of the annular metal wire on the cutting net 6, the push rod 503 pushes the spring lock 501. After the spring locks 501 at both ends are opened, the tension spring 502 is stretched to contract a part of the soft shell of the medicine injection cavity 4. The thrombolytic drug inside the medicine injection cavity 4 is ejected through the check valve 19 to perform thrombolysis and cutting on the thrombus that is difficult to treat. After the drug is ejected, the check valve 19 automatically closes to prevent blood from flowing back into the medicine injection cavity 4.

[0078] Finally, limited by the check valve 19, the tension spring 502 will not be ejected with the thrombolytic drug.

[0079] Compared with the related technology, a thrombus treatment and care device for thrombus treatment provided in this embodiment has the following beneficial effects:

[0080] When the cutting net 6 cuts the thrombus that is difficult to treat, the cutting net 6 pushes the push rod 503. After the two spring locks 501 are opened, the tension spring 502 contracts the medicine injection cavity 4 and ejects the drug through the check valve 19. Cutting the thrombus after thrombolysis can more efficiently treat the thrombus that is difficult to cut. After removal, the blocked thrombus can be restored to avoid long-term blockage from damaging the patient's health, and the more difficult thrombus mass can be treated in a short time.

[0081] Third Embodiment

[0082] Please refer to Figures 6 - 10 , based on a thrombus treatment and care device for thrombus treatment provided in the first embodiment of the present application, the third embodiment of the present application proposes another thrombus treatment and care device for thrombus treatment. The third embodiment is only the preferred mode of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0083] Specifically, the difference of a thrombus treatment and care device for thrombus treatment provided in the third embodiment of the present application is that a turbine 18 is fixedly installed on one side of the cutting net 6, and the turbine 18 is arranged inside the diversion shell 505.

[0084] The cutting net 6 is rotatably connected to the axis of the sealing cover 16 through a connecting column 7.

[0085] A circular groove 15 is provided on the outer ring of the cutting net 6, and the circular groove 15 is adaptively installed with one end of the negative pressure extraction cavity 3.

[0086] During the actual use process, as shown in Figure 10 , when the device is in the initial position, it is in a non-working state. The next step of the device is the motion state when thrombus treatment is in progress, and the last step of the device is a schematic diagram after all thrombus treatments are completed;

[0087] The surface of the turbine 18 is in close contact with the inner wall of the diversion housing 505;

[0088] When the cutting net 6 rotates, the sealing cover 16 does not rotate;

[0089] The surface of the turbine 18 has inclined grooves to facilitate driving rotation when the drug is ejected.

[0090] The working principle of a thrombus treatment and care device for thrombus treatment provided in this embodiment is as follows:

[0091] When dealing with difficult-to-treat thrombi, the stretching spring 502 drives the medicine injection cavity 4 to contract and eject thrombolytic drugs. When the drug flows through the turbine 18 after passing through the check valve 19, it drives the turbine 18 to rotate. The turbine 18 and the cutting net 6 are fixedly installed, so the cutting net 6 also rotates accordingly to rotate and cut the thrombus mass.

[0092] Compared with the related art, a thrombus treatment and care device for thrombus treatment provided in this embodiment has the following beneficial effects:

[0093] When the drug in the medicine injection cavity 4 is ejected, it drives the turbine 18 to rotate. The turbine 18 drives the cutting net 6 to rotate to perform axial cutting and rotational cutting on the thrombus mass at the same time, which can improve the cutting efficiency. The process has no driving equipment, the structure is simpler, it can protect the patient from secondary injury, and the cutting is more complete to avoid recurrence.

[0094] Fourth Embodiment

[0095] Please refer to Figure 9 , based on a thrombus treatment and care device for thrombus treatment provided in the first embodiment of the present application, the fourth embodiment of the present application proposes another thrombus treatment and care device for thrombus treatment. The fourth embodiment is only the preferred mode of the first embodiment, and the implementation of the fourth embodiment will not affect the independent implementation of the first embodiment.

[0096] Specifically, the difference of a thrombus treatment and care device for thrombus treatment provided in the fourth embodiment of the present application is that a sharp cone 14 is fixedly installed at the right end of the drive box 12.

[0097] The working principle of a thrombus treatment and care device for thrombus treatment provided in this embodiment is as follows:

[0098] After the device is placed and reaches the lesion area, that is, the area where thrombus is generated in the blood vessel, when the structure inside the sleeve 1 is pushed out manually externally, the sharp cone 14 is used to reduce the resistance for movement.

[0099] Compared with the related technologies, a thrombus treatment and care device for thrombus treatment provided by this embodiment has the following beneficial effects:

[0100] By setting the taper 14 to reduce the resistance of passing through vascular thrombus and reducing the contact area to avoid pushing the thrombus to produce displacement when advancing, which may cause harm to the patient.

[0101] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
