Description
Technical Field
The disclosure relates to the technical field of medical equipment, in particular to an aortic stent, an implantation method thereof and an aneurysm intra-cavity pressure monitor.
Background
The aorta is the main part of the human blood circulation system and is the great vessel originating from the heart. Aortic aneurysms are a not uncommon lesion that occurs in the aorta, and unlike conventional tumors, are aortic luminal dilatations, as well as thinning of certain parts of the bicycle tire to form a bulge. When the expanded diameter exceeds the normal aortic diameter by 1.5 times, it is defined as an aortic aneurysm lesion. The aortic aneurysm is like a timing bomb of a human body and has fatal danger at any time. Most of the medical methods use the aortic endovascular stent repair to treat the aortic aneurysm. The aortic aneurysm is treated by the endoluminal stent repair method by implanting an artificial stent, so that the interaction between the wall of an arterial blood vessel thinned due to expansion lesion and blood pressure is isolated, and the fragile wall of the blood vessel is protected from expanding and even cracking.
Although the success rate of aortic endoluminal stent repair can reach over 90% and patients recover quickly, there is still some potential for postoperative complications, the most serious of which is endoleak. Endoleak refers to the failure of the aortic stent to completely isolate the lesion, so that blood flow can still enter the aneurysm cavity. After the internal leakage occurs, partial cases can be sealed by themselves, but a certain proportion of patients still have tumor cavities which are continuously enlarged, and the patients can even threaten life without intervention again.
The internal leakage can cause continuous high pressure in a tumor cavity, and is a direct reason for further worsening of the disease condition of the aortic aneurysm after the aortic intracavity stent repair. However, the occurrence of the endoleak has certain randomness and hysteresis, and the endoleak cannot be monitored and intervened in a short time, so that the real-time monitoring of the pressure in the aortic aneurysm cavity is an important and reliable follow-up means.

Detailed Description
As described in the background, real-time monitoring of the pressure in the aneurysm cavity is of great importance in monitoring the occurrence of endoleaks after aortic endoluminal stent repair. The main means adopted for monitoring the pressure in the aortic aneurysm cavity in the related technology is as follows: the pressure monitoring component is implanted into a tumor cavity for direct measurement by utilizing a catheter puncture technology, and although the method has high data reliability, the method can possibly cause certain damage to the fragile blood vessel wall of a patient to cause adverse reaction and complications; in addition, the method needs the implementation of the patient in a hospital, and cannot realize the real-time monitoring of the pressure in the tumor cavity, which may cause the delay of the disease condition.
Based on the current situation, the technical scheme of the disclosure provides: make into the film form with the forced induction part to link to each other with the support main part that is used for isolated patient's aortic aneurysm chamber, make when carrying out aorta intracavity support repair art, the forced induction part can curl in the lump and attach to the support main part outside along with the support main part, thereby implant the position in the lump, catheter puncture causes the injury to patient's vascular wall when can avoiding implanting pressure monitoring part alone. Pressure data obtained by sensing of the pressure sensing component is transmitted to the outside of the patient body in a wireless transmission mode; energy is supplied to the pressure sensing component through the electromagnetic induction principle so as to ensure the normal work of the pressure sensing component, and therefore the real-time monitoring of the pressure in the active aneurysm cavity is realized.
The foregoing is the core idea of the technical solution of the present disclosure, and in order to make the above objects, features and advantages of the present disclosure more comprehensible, the technical solution in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
As shown in fig. 1, the presently disclosed embodiment provides an aortic stent 2, the aortic stent 2 comprising: a holder main body 21, and a pressure sensing part 22 connected to the holder main body 21. Wherein, the stent main body 21 is used for being implanted into the body of a patient and isolating the aortic aneurysm cavity 1 of the patient. The pressure sensing part 22 can be implanted into the patient along with the holder body 21, for example, the pressure sensing part 22 may be formed in a film shape as a whole, which facilitates implantation into the patient along with the holder body 21; the pressure sensing component 22 is used for sensing the pressure in the aortic aneurysm cavity 1 in real time and sending the sensed pressure data to the outside of the patient; in particular, the pressure sensing part 22 can transmit the pressure data in a wireless transmission manner, and in addition, the pressure sensing part 22 can generate electric energy for self-operation under the induction of the resonant electromagnetic wave outside the body of the patient, so that the pressure sensing part 22 can independently operate in the in-vivo environment in a state without an external circuit and a battery.
As a possible design, as shown in fig. 2 and 3, in the above-described aortic stent 2, the pressure-sensitive member 22 includes: a film substrate 221, and a pressure sensor 222, a pressure signal transmitter 223 and an energy receiver 224 disposed on the film substrate 221.
The pressure sensor 222 is used for sensing the pressure in the aortic aneurysm cavity in real time to generate a pressure sensing signal. In order to make the pressure sensing member 22 have a film shape as a whole, a film pressure sensor may be used as the pressure sensor 22.
Illustratively, as shown in fig. 4, the pressure sensor 222 is mainly composed of a pressure-sensitive film M and a conductive film N; the forming material of the pressure-sensitive film M may be a pressure-sensitive material, such as a pressure-sensitive nanomaterial; the material for forming the conductive film N may be a conductive metal paste, such as a conductive silver paste. When the pressure sensor 22 works, the pressure-sensitive film M is deformed when being pressed, so that the internal resistance thereof changes, and the pressure can be obtained by detecting the change of the resistance.
The manufacturing process of the pressure sensor 22 may be as follows: firstly, printing a pressure-sensitive film M with a specific pattern on a film substrate 221 by adopting a pressure-sensitive nano material through a film printing technology; then, uniformly coating conductive silver paste in gaps of the patterns of the pressure-sensitive film M to form a conductive film N; while forming the conductive film N, a conductive silver paste may be used to form a circuit 226 connected to the conductive film N on the film substrate 221; and then packaging the manufactured pressure-sensitive film M and the manufactured conductive film N to protect the pressure-sensitive film M and the conductive film N.
The pressure-sensitive nano material is printed on a film base material through a film printing technology, a thin layer of conductive silver paste is uniformly coated in a gap in the structure before packaging, and then the film is packaged.
Since the pressure sensor 222 needs to be directly contacted with the blood of the human body to accurately sense the blood pressure change, the pressure sensor 222 is formed of a biocompatible material. In addition, in order to adapt to the environment in the human body, the working temperature range of the pressure sensor 222 is 32 ℃ to 45 ℃, and the pressure range in the fluid is 0mmHg to 250mmHg.
With continued reference to fig. 2 and 3, the pressure signal transmitter 223 is connected to the pressure sensor 222 for converting the pressure sensing signal generated by the pressure sensor 222 into a communication signal in real time, and transmitting the communication signal to the outside of the patient. By converting the pressure sensing signals into communication signals, the real-time pressure data in the aortic aneurysm cavity can be transmitted in a wireless transmission mode.
As a possible design, the pressure signal transmitter 223 may include a transmitting-end Bluetooth module, which can adopt the ordinary Bluetooth technology or Bluetooth Smart technology to convert the pressure sensing signal into a Bluetooth communication signal in real time and transmit the Bluetooth communication signal to the outside of the patient. It should be noted that the Bluetooth Smart technology for transmitting communication signals has the advantages of low power consumption and good anti-interference performance, and is suitable for the pressure signal transmitter 223 implanted in a human body.
With continued reference to fig. 2 and 3, the energy receiver 224 is connected to the pressure sensor 222 and connected to the pressure signal transmitter 223 for generating electric energy under the induction of the resonant electromagnetic wave outside the body, and supplying the generated electric energy to the pressure sensor 222 and the pressure signal transmitter 223, so that the pressure sensor 222 and the pressure signal transmitter 223 operate normally.
It should be noted that the energy receiver 224 is not shown in fig. 2 and 3 as being directly connected to the pressure sensor 222, and in fact, the energy receiver may be connected to the pressure sensor through the pressure signal transmitter 223 located in the middle.
For example, as shown in fig. 5, the energy receiver 224 may include a wireless charging coil E, and a current lead-out wire F connected to the wireless charging coil E. When external transmission resonance electromagnetic wave, wireless charging coil E charges through the electromagnetic induction mode, and it induces magnetic field variation and produces the electric current, exports pressure signal transmitter 223 and pressure sensor 222 through electric current derivation line F, realizes providing the electric energy for the two.
With reference to fig. 5, in order to adapt to the requirement that the pressure sensing part 22 is overall film-shaped, the wireless charging coil E may be a disk-shaped film metal ring coil. When the disk-shaped thin film metal ring coil is manufactured, a thin film printing technology can be adopted, and the metal slurry is directly printed on the thin film substrate 221 to form the disk-shaped thin film metal ring coil. The current lead-out line F may also be formed along with the disk-shaped thin-film metal ring coil.
Referring again to fig. 2 and 3, the pressure-sensing component 22 in the present embodiment may further include a protective layer 225 (in fig. 2, the protective layer 225 is processed by translucency), and the protective layer 225 covers the pressure signal transmitter 223 and the energy receiver 224 inside to protect the two. The protective layer 225 is provided with an opening (not shown in the figure), the pressure sensor 222 is connected with the pressure signal transmitter 225 and the energy receiver 224 through a line passing through the opening, and the opening is sealed by a sealing material, so that the pressure signal transmitter 223 and the energy receiver 224 are completely covered by the protective layer 225, and blood is prevented from entering the protective layer 225 and damaging the pressure signal transmitter 223 and the energy receiver 224.
The protective layer may be formed of a biocompatible thin film material to use the internal environment of the human body.
In addition, in this embodiment, the material forming the film substrate 221 may be an organic polymer material, which has better corrosion resistance and can provide a stable and reliable support base for the components included in the pressure sensing component 22.
Referring to fig. 1 again, in the present embodiment, the stent main body 21 of the aortic stent 2 and the pressure sensing component 22 can be connected by a wire made of a biocompatible material, so that after the aortic stent 2 is implanted into a patient, the stent main body 21 isolates an aortic aneurysm cavity, and the pressure sensing component 22 is suspended outside the stent main body 21 (the side of the stent main body facing the aortic aneurysm cavity is referred to as the outside thereof) and is located in the aortic aneurysm cavity, thereby facilitating real-time sensing of the pressure in the aneurysm cavity. The yarn may be a polyester yarn.
The aortic stent 2 provided in the embodiments of the present disclosure is described above in detail, and based on this, the method for implanting the aortic stent will be described below.
Step S1: the stent main body 21 and the pressure-sensitive member 22 of the aortic stent 2 provided in the embodiment of the present disclosure are collectively crimped in a cylindrical shape, and the pressure-sensitive member 22 is attached to the outside of the stent main body 21 after crimping.
In the above step S1, the reason why the aortic stent 2 is in a radially compressed state after being crimped is that the aortic stent 2 needs to be placed in a delivery sheath for delivering the aortic stent 2, and therefore the diameter of the aortic stent 2 crimped in a cylindrical shape depends on the diameter of the delivery sheath. And after the rolling, the film-shaped pressure sensing member 22 can be attached to the outside of the stent body 21 by means of the physical force of the film surface, so that the pressure sensing member 22 can be conveyed together with the stent body 21 during the conveyance of the aortic stent 2.
It should be noted that the conventional pressure-sensitive members are mostly in the form of a straight cylinder or a cylindrical shape, and thus, when the aortic stent is compressed, the compression capacity of the pressure-sensitive members is very limited. In the embodiment of the present disclosure, the pressure sensing part 22 is formed in a film shape, so that the pressure sensing part 22 can be curled and attached to the outside of the compressed stent main body, thereby effectively reducing the compression volume.
Step S2: the stent main body 21 and the pressure sensing part 22 are conveyed to the position of the aortic aneurysm in the body of the patient by using a conveying sheath; thereafter, the stent body 21 self-expands, isolating the aneurysm cavity; the pressure sensing component 22 is deployed, is positioned in the aortic aneurysm cavity, is in direct contact with blood, starts to sense the pressure in the aneurysm cavity in real time, and sends the sensed pressure data to the outside of the patient body in a wireless transmission mode.
In the implantation method of the aortic stent 2, the stent main body 21 for isolating an aortic aneurysm cavity is implanted, and the pressure sensing component 22 for sensing the pressure in the aneurysm cavity is also implanted, so that the injury of the vessel wall of a patient caused by catheter puncture pressure monitoring is avoided, and adverse reactions and complications caused by the injury are effectively reduced.
The embodiment of the present disclosure further provides an aortic aneurysm cavity pressure monitor, as shown in fig. 6, the pressure monitor 3 is used in cooperation with the aortic stent 2, and is configured to receive pressure data sent by the pressure sensing component 22 of the aortic stent 2 in a wireless transmission manner in real time, so as to monitor the pressure in the aortic aneurysm cavity in real time; further, the pressure monitor 3 can generate resonant electromagnetic waves to transmit energy to the pressure sensing component 22 in a wireless manner (specifically, in an electromagnetic induction manner), so that the pressure sensing component 22 can normally perform pressure sensing operation. It can be seen that the pressure monitor 3 in this embodiment is mainly used for pressure monitoring and energy supply.
As a possible implementation manner of the technical solution based on the pressure monitor, as shown in fig. 7 and 8, the pressure monitor 3 includes: pressure signal receiver 31, display screen 32, energy transmitter 33, processor 34, and power module 35.
The pressure signal receiver 31 is matched with the pressure signal transmitter 223 of the pressure sensing component 22 in the aortic stent 2, and is used for receiving the communication signal sent by the pressure signal transmitter 223 in real time and converting the received communication signal into pressure data, so as to perform operations such as analysis, processing, calculation, display and the like on the pressure data.
As a possible implementation manner, a transmitting end bluetooth module is provided in the pressure signal transmitter 223, a receiving end bluetooth module matched with the pressure signal receiver 31 is provided in the pressure signal receiver 31, and communication between the two bluetooth modules is implemented through bluetooth technology.
The display screen 32 is connected with the pressure signal receiver 31 and is used for displaying the pressure data obtained by conversion of the pressure signal receiver 31 in real time so as to visually reflect the disease development, so that the patient and family members thereof can visually see the pressure and change conditions in the aortic aneurysm cavity of the patient and can record and analyze the pressure data.
The display screen 32 mainly displays real-time pressure data in the tumor cavity, a pressure peak value and a pressure average value in a cardiac cycle, and also can display information such as date, electric quantity, network signal intensity and the like, and in addition, functional keys such as 'alarm', 'signal intensity', 'data upload' and the like can be added, so that the patient or the family members thereof can operate according to the needs. Such as: when the patient or the family members find that the pressure data is abnormal, an alarm key can be pressed down, and the abnormal condition is reported to a doctor or a hospital so as to take effective intervention measures on the state of an illness in time; the patient or the family members can adjust the signal intensity of the resonant electromagnetic wave emitted by the energy emitter 33 by operating the function key of 'signal intensity' so as to ensure that the energy supply of the energy emitter 33 to the pressure sensing part 22 in the body is normally maintained; the patient or family members of the patient can upload the pressure data in a period to the cloud server by operating the data uploading function key, so that doctors or hospitals can conveniently call the pressure data from the cloud server to monitor the state of illness of the patient.
If the pressure monitor 3 is worn on the human body, the display screen 32 is preferably flexible, for example, a flexible liquid crystal display panel is used to fit the muscle curve of the human body, so that the wearing comfort of the patient is improved. For example: if the pressure monitor 3 is worn on the arm of the patient, the display screen 32 can be curved to fit the curve of the arm of the patient.
The energy transmitter 33 is matched with the energy receiver 224 of the pressure sensing part 22 in the aortic stent 2, and is used for generating resonant electromagnetic waves capable of causing the energy receiver 224 to induce, so that the energy receiver 224 generates electric energy under the action of electromagnetic induction, and the purpose of supplying energy to the pressure sensing part 22 in a wireless transmission mode is achieved.
The range of resonant electromagnetic waves emitted by the energy emitter 33 is determined by the specific need to ensure that the pressure-sensitive member 22 is within this range. Such as: in the case where the pressure monitor 3 is worn on the arm of the patient, the distance between the pressure monitor 3 and the in-vivo pressure-sensitive member 22 is short, and even when the patient performs an operation such as raising the arm, the distance between the two does not generally exceed 1 meter, so that the energy transmitter 33 can be set to emit a resonant electromagnetic wave in a range of 1 meter in the peripheral radius.
The processor 34 is connected to various components in the pressure monitor 3, such as the pressure signal receiver 31, the display screen 32, the energy transmitter 33, the power module 35, and the like, for respectively controlling the various components to operate normally.
The power module 35 is connected to various components in the pressure monitor 3, such as the pressure signal receiver 31, the display screen 32, the energy transmitter 33, the processor 34, and the like, and is configured to provide electric energy for normal operation of the components.
With continued reference to fig. 7 and 8, the pressure monitor 3 may be worn on a human body, such as a forearm of the human body, and therefore the pressure monitor 3 may further include a wearable fixing kit 36, and the components of the pressure monitor 3, such as the pressure signal receiver 31, the display screen 32, the energy transmitter 33, the processor 34, the power module 35, and the like, are fixed on the wearable fixing kit 36.
Based on this, as a possible implementation manner, the display screen 32 may be disposed on the outer side of the wearable fixed external member 36 (the side of the wearable fixed external member 36 facing away from the corresponding human body part is the outer side thereof) so as to facilitate the intuitive observation of the real-time pressure data; the pressure signal receiver 31, the energy emitter 33, the processor 34, and the power module 35 are disposed inside the wearable fixed external member 36 (the side of the wearable fixed external member 36 facing the corresponding human body part is the inner side), so as to save space and reduce the overall size of the pressure monitor 3.
Referring to fig. 8, the pressure monitor 3 may further include a wifi module 37, which may be disposed on the wearable fixed kit 36, and is connected to the pressure signal receiver 31, for uploading the pressure data received by the pressure signal receiver 31 to the cloud server, so that the doctor can monitor the pressure in the aneurysm cavity of the patient, thereby implementing effective intervention before the condition of the patient deteriorates.
In addition, the pressure monitor 3 may further include an alarm module (not shown) which can be disposed on the wearable fixed kit 36 and alarm the patient and the family members when monitoring abnormal pressure data. Alarm module still can set up in cloud ware, pressure monitor 3 can be through wifi module 37 with real-time pressure data upload to the cloud ware in, when alarm module in the cloud ware monitors pressure data unusual, can be in time send out the police dispatch newspaper to doctor or hospital guardianship personnel, feed back, so that the doctor carries out analysis and processing to unusual data, if data show that the patient has the illness condition to worsen the risk, in time inform the patient in time to seek medical advice, thereby implement effectual intervention measure to the patient before the patient's state of an illness worsens, improve patient survival rate.
