Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a shaping device for treating cardiac ventricular aneurysm. Background Art

[0002] Ventricular aneurysm is a common complication after acute myocardial infarction, with an incidence rate of 5%-20%. Myocardial ischemia causes myocardial necrosis. After the necrotic myocardium is replaced by fibrous connective tissue, it will form pathological changes that bulge outward and appear band-shaped, cystic or irregular, accompanied by the disappearance or reverse movement of the ventricular wall motion. This series of changes will then cause serious complications such as heart failure, mural thrombosis and even heart rupture, which will greatly harm the patient's prognosis.

[0003] Currently, the treatment for ventricular aneurysms mainly adopts surgical methods, that is, by removing the bulging ventricular wall and reinforcing the patch in situ. However, since the shape and size of the patch will have a corresponding impact on the overall volume and shape of the ventricular wall, some patients will experience changes in ventricular volume and shape after repair, which will still cause certain problems in patients' cardiac function and ventricular wall motion. In view of this, how to assist surgeons in restoring the ventricular shape and volume to the greatest extent during the treatment of ventricular aneurysms has become a problem that needs to be solved urgently. Summary of the invention

[0004] The purpose of the present invention is to provide a shaping device for treating cardiac ventricular aneurysm to solve the problems existing in the above-mentioned prior art, improve the accuracy of the shape and size of the patch during the treatment of ventricular aneurysm, and avoid the situation where the patient's ventricular volume and shape are changed after the patch.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] The present invention provides a shaping device for treating cardiac ventricular aneurysm, comprising:

[0007] An airbag, wherein a vent is provided on the airbag, the vent is connected to a ventilating tube, and the shape and size of the airbag after inflation match the shape and size of the ventricular cavity of the patient requiring surgery;

[0008] An inflatable device, wherein one end of the vent pipe away from the airbag is connected to an air outlet of the inflatable device, and the inflatable device is used to inflate the airbag;

[0009] The delivery catheter is used to be placed in the rupture formed after the diseased bulging ventricular wall is removed from the patient's heart, and serves as a channel for the balloon to enter and leave the ventricle.

[0010] Preferably, the airbag is made of silicone or polyethylene.

[0011] Preferably, the ventilation tube and the delivery catheter are made of silicone or plastic.

[0012] Preferably, before the operation, the image data of the ventricular cavity of the patient requiring surgery is obtained, and the shape of the ventricular cavity of the patient requiring surgery is restored using image processing software to obtain the shape and size of the ventricular cavity of the patient requiring surgery;

[0013] Then, a mold is made by 3D printing, so that the shape and size of the mold cavity match the shape and size of the ventricular cavity of the patient requiring surgery;

[0014] The mold is then used to make the airbag, so that the shape and size of the airbag after inflation can match the shape and size of the ventricular cavity of the patient requiring surgery.

[0015] Preferably, the ventilation pipe is a hose.

[0016] Preferably, the ventilation pipe is detachably connected to the air outlet of the inflation device.

[0017] Preferably, the inner diameter of the delivery catheter is large enough for the airbag to pass through the delivery catheter after being deflated.

[0018] Preferably, the outer diameter of the ventilation tube is smaller than the inner diameter of the delivery catheter.

[0019] Preferably, the inflation device adopts an electric inflation pump.

[0020] Preferably, the delivery catheter is a hard tube.

[0021] Compared with the prior art, the present invention has achieved the following technical effects:

[0022] The shaping device for treating cardiac ventricular aneurysm of the present invention can assist the patch during surgery, improve the accuracy of the shape and size of the patch, and thus avoid changes in the patient's ventricular volume and shape after the patch, effectively improve the degree of restoration of the original ventricular form during the treatment of ventricular aneurysm, and help improve the patient's postoperative cardiac function and ventricular wall motion.

[0023] Furthermore, the present invention obtains the image data of the ventricular cavity of the patient who needs surgery, restores its shape using image processing software, and then uses 3D printing to make a mold to make an airbag that matches the shape and size of the patient's ventricular cavity. During the operation, the airbag can accurately fit the ventricular cavity after being inflated, avoiding changes in ventricular volume and shape caused by inappropriate patches. Moreover, the device is precisely made according to the specific conditions of the ventricular cavity of different patients, further improving the adaptability of the device to individual differences of different patients, thereby improving the pertinence and effectiveness of the treatment effect.

[0024] Furthermore, the delivery catheter in the device can be placed at the rupture formed after the lesion is removed from the patient's heart and the ventricular wall bulges, serving as a channel for the airbag to enter and leave the ventricle, providing a convenient operating path for the surgeon to place and remove the airbag during surgery, making the application of the entire shaping device during the operation more convenient and controllable, and can better assist the surgeon to complete the surgical operation and improve the efficiency and accuracy of the operation.

[0025] Furthermore, the airbag is made of high polymer molecular materials (such as silicone and polyethylene) that are anti-adhesion, low-rejection, and plastic, and the ventilation tube and delivery catheter are made of silicone or plastic and hard tube materials respectively. The selection of these materials not only considers the compatibility with human tissue, but also takes into account the functional requirements of each in the device. For example, the ventilation tube uses a soft tube for easy connection and gas transmission, and the delivery catheter uses a hard tube to better maintain the channel stability at the heart rupture, ensuring the smooth entry and exit of the airbag.

[0026] Furthermore, the ventilation tube is detachably connected to the outlet of the inflation device, which is convenient for assembly, disassembly and maintenance of the device before and after the operation. At the same time, the inner diameter of the delivery catheter is large enough to allow the airbag to pass through after it is deflated, and the outer diameter of the ventilation tube is smaller than the inner diameter of the delivery catheter. These size designs ensure good coordination between the various components, making the entire shaping device smoother and more reliable during use, and reducing the risk of failure that may occur due to component connection or size mismatch.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 3 As shown, this embodiment provides a shaping device for treating cardiac ventricular aneurysm, comprising:

[0036] An airbag 1 is provided with a vent, the vent is connected to a vent tube 2, and the shape and size of the airbag 1 after inflation match the shape and size of the ventricular cavity of the patient requiring surgery;

[0037] An inflating device, wherein one end of the vent pipe 2 away from the airbag 1 is connected to an air outlet of the inflating device, and the inflating device is used to inflate the airbag 1;

[0038] The delivery catheter 3 is used to be placed in the rupture formed after the diseased bulging ventricular wall is removed from the patient's heart, and serves as a channel for the airbag 1 to enter and leave the ventricle.

[0039] The shaping device for treating cardiac ventricular aneurysm of the present embodiment can assist in patching during surgery. Before patching, the delivery catheter 3 is placed in the rupture formed after the diseased bulging ventricular wall is removed from the patient's heart, and then the airbag 1 is passed through the delivery catheter 3 to be placed in the patient's ventricle that requires surgery, and then the airbag 1 is inflated. Since the inflated airbag 1 matches the shape and size of the ventricular cavity that requires surgery, when patching is performed on this basis, the shape and size of the patch can be standardized, and the accuracy of the shape and size of the patch can be improved, thereby avoiding the situation where the patient's ventricular volume and shape change after the patch, effectively improving the degree of restoration of the original ventricular shape during the treatment of ventricular aneurysm, and helping to improve the patient's postoperative cardiac function and ventricular wall motion.

[0040] The delivery catheter 3 in the device can be placed at the rupture formed after the lesion is removed from the patient's heart and the ventricular wall bulges out, serving as a channel for the balloon 1 to enter and leave the ventricle, providing a convenient operating path for the surgeon to place and remove the balloon 1 during surgery, making the application of the entire shaping device during the operation more convenient and controllable, and can better assist the surgeon to complete the surgical operation and improve the efficiency and accuracy of the operation.

[0041] In the optional scheme of this embodiment, it is more preferred that the airbag 1 is made of an anti-adhesion, low-rejection, and plastic high-polymer molecular material (such as silicone, polyethylene), so that the airbag 1 has good compatibility with human tissues while taking into account the inflation and expansion characteristics of the airbag 1.

[0042] In the optional scheme of this embodiment, preferably, the materials of the ventilation tube 2 and the delivery catheter 3 are silicone or plastic, the ventilation tube 2 is a hose, and the delivery catheter 3 is a hard tube. The ventilation tube 2 is a hose for easy connection and gas transmission, and the delivery catheter 3 is a hard tube to better maintain the channel stability at the heart rupture, ensuring the smooth entry and exit of the airbag 1.

[0043] In the optional scheme of this embodiment, it is more preferred that before the operation, by obtaining the image data of the ventricular cavity of the patient requiring the operation, the shape of the ventricular cavity of the patient requiring the operation is restored by using image processing software to obtain the shape and size of the ventricular cavity of the patient requiring the operation;

[0044] Then, the mold 4 is manufactured by 3D printing, so that the shape and size of the cavity of the mold 4 match the shape and size of the ventricular cavity of the patient requiring surgery;

[0045] Then, the mold 4 is used to make the airbag 1 so that the shape and size of the airbag 1 after inflation can match the shape and size of the ventricular cavity of the patient requiring surgery.

[0046] This embodiment obtains the image data of the ventricular cavity of the patient who needs surgery, restores its shape using image processing software, and then makes a mold 4 through 3D printing to make an airbag 1 that matches the shape and size of the patient's ventricular cavity. During the operation, the airbag 1 can accurately fit the ventricular cavity after being inflated, avoiding the change of ventricular volume and shape caused by an inappropriate patch. Moreover, the device is accurately made according to the specific conditions of the ventricular cavity of different patients, further improving the adaptability of the device to the individual differences of different patients, thereby improving the pertinence and effectiveness of the treatment effect.

[0047] In the optional scheme of this embodiment, it is more preferred that the ventilation tube 2 is detachably connected to the air outlet of the inflation device, which is convenient for assembling, disassembling and maintaining the device before and after the operation. At the same time, the inner diameter of the delivery catheter 3 is large enough to allow the airbag 1 to pass through after being deflated, and the outer diameter of the ventilation tube 2 is smaller than the inner diameter of the delivery catheter 3. These size designs ensure good coordination between the various components, making the entire forming device smoother and more reliable during use, and reducing the risk of failure that may occur due to component connection or size mismatch.

[0048] It is worth noting that the inner diameter of the delivery catheter 3 is large enough to allow the airbag 1 to pass through the delivery catheter 3 after being deflated. Preferably, the outer diameter of the ventilation tube 2 is smaller than the inner diameter of the delivery catheter 3, and the inflation device adopts an electric inflation pump.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
