Description

Technical Field

[0001] The present invention relates to the technical field related to medical auxiliary equipment, and in particular to an intelligent hydrogel injection system that can be used for localized abdominal aortic dissection. Background Art

[0002] Aortic dissection (AD), also known as aortic dissecting aneurysm, is a serious cardiovascular emergency caused by a rupture in the aortic intima, through which blood enters the middle layer of the arterial wall, forming a dissecting hematoma, and gradually extending and peeling off the intima and media of the aorta. The aortic cavity at the lesion site is divided into a true cavity and a false cavity by the intima, which may or may not be connected, and blood flowing between them may form a thrombus.

[0003] Currently, the treatment options for aortic dissection are: (1) open surgery: artificial blood vessel replacement; (2) minimally invasive surgery: endovascular intervention, covered stent implantation.

[0004] Current treatment methods usually require implantation of covered stents, but these stents cannot be degraded and are accompanied by risks such as endoleaks, which may lead to long-term vascular complications such as stent infection, endoleaks, and stent migration. In this regard, hydrogel injection can be used to replace covered stents. However, the existing sheaths are unstable when puncturing the vascular endothelium, which can easily cause vascular rupture and bleeding. It is necessary to develop a stable system that can resist the reaction force of the puncture needle. In addition, the use of coils to embolize the false lumen is costly and interferes with subsequent CT examinations. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent hydrogel injection system that can be used for localized abdominal aortic dissection to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0025] See also Figure 1-Figure 3 In an embodiment of the present invention, a smart hydrogel injection system for localized abdominal aortic dissection includes an external tube 1 and also includes:

[0026] A stabilization auxiliary mechanism, which is disposed on the external pipe 1 and is capable of performing an expansion action on the outer wall of the external pipe 1 to limit the position of the external pipe 1;

[0027] The assembly structure is arranged in a columnar shape and is located inside the external pipe 1;

[0028] The puncture component is arranged in the assembly structure and matched with the assembly structure. The puncture component can infuse two colloids and mix the two colloids at the delivery tail end.

[0029] Among them, it should be supplemented that, in actual use, the two colloids can be delivered through the puncture component and mixed at the delivery tail end, and finally reach the false lumen, promote thrombosis in the aneurysm cavity, and reduce the risk of rupture of abdominal aortic dissecting aneurysm. During the specific operation, medical staff can manipulate the stabilization auxiliary mechanism to prompt the stabilization auxiliary mechanism to perform an expansion action on the outer wall of the external tube 1, so that the external tube 1 is limited, the stabilization auxiliary function is realized, the safety and stability of the operation are improved, and it is suitable for popularization and use.

[0030] It should be emphasized that the hydrogel used in the present invention is a biodegradable material, which avoids the risk of long-term complications.

[0031] Please refer again Figure 1 and Figure 2 , the stabilization auxiliary mechanism includes two groups of inflatable balloon groups arranged on the outer wall of the external tube 1, and the inflatable balloon group includes multiple No. 1 balloons 2 and No. 2 balloons 3. The external tube 1 is a flexible tube body. The end of the external tube 1 away from the inflatable balloon group is provided with a first inflation port 5 and a second inflation port 5-1, the first inflation port 5 is used to inflate the No. 1 balloon 2, so that it can expand relatively and squeeze the tube body of the external tube 1 to make it twist, so that its front end outlet can be directed to the puncture site, which is convenient for subsequent puncture operations; the second inflation port 5-1 is used to inflate the No. 2 balloon 3, so that it can expand relatively, and supplement the position of the external tube 1 in the blood vessel. The No. 1 balloon 2 and the No. 2 balloon 3 are both arranged in a semicircular ellipsoid shape, and the No. 1 balloon 2 is larger than the No. 2 balloon 3.

[0032] For example, in actual use, since the ellipsoid shape can improve the contact surface to a certain extent, compared with the No. 1 balloon 2 and the No. 2 balloon 3 which are both spherical, the ellipsoid balloon has better stability.

[0033] In specific implementation, the first inflation port 5 and the second inflation port 5-1 can be used to inflate the No. 1 balloon 2 and the No. 2 balloon 3 respectively. It should be noted that the No. 1 balloon 2 and the No. 2 balloon 3 are controlled separately. After the No. 1 balloon 2 and the No. 2 balloon 3 are inflated, the external tube 1 can be directed toward the puncture position and stably limited, which is convenient for medical staff to perform subsequent operations.

[0034] Furthermore, by adjusting the expansion degree of the multiple balloons, the orientation of the external tube 1 can also be adjusted, and accordingly, the puncture angle can be adjusted, which can be selected according to the actual puncture needs, thereby greatly improving the practicality.

[0035] Secondly, preferably, the number of the No. 1 balloon 2 is 2, the number of the No. 2 balloon 3 is 4, the No. 1 balloon 2 is larger than the No. 2 balloon 3, and the two No. 1 balloons 2 are arranged diagonally up and down, which plays a role in changing the injection direction, and the four No. 2 balloons 3 are arranged diagonally up and down and mirror-imaged with the main balloon connecting line, which plays a role in stabilizing the cannula.

[0036] Please refer again Figure 2 and Figure 3 The assembly structure includes an internal pipe fitting 6 arranged inside the external pipe fitting 1, the internal pipe fitting 6 is adapted to the external pipe fitting 1, and the two are slidably fitted, and the internal pipe fitting 6 is adapted to the puncture assembly.

[0037] The puncture assembly includes two puncture tubes 8 arranged inside the built-in tube 6. The two puncture tubes 8 are parallel to each other and symmetrical about the central axis of the built-in tube 6. The top of the built-in tube 6 is provided with a conducting structure adapted to the two puncture tubes 8.

[0038] The conduction structure includes two reserved holes 7 arranged at the top end of the built-in tube 6 , and the reserved holes 7 are adapted to the puncture tube 8 . The puncture tube 8 can move along the axial direction of the built-in tube 6 through the reserved holes 7 .

[0039] During specific implementation, medical personnel can inject different colloids into the tail ends of the two puncture tubes 8, and the two colloids can be transported through the two puncture tubes 8 respectively, and finally mixed at the transport terminal.

[0040] Two handles 4 are fixedly provided at one end of the external tube 1 away from the No. 1 balloon 2 and the No. 2 balloon 3 , and the two handles 4 are symmetrical about the center of the external tube 1 .

[0041] The two handles 4 are provided to facilitate the operation of the medical staff.

[0042] Furthermore, the handle 4 may also be replaced with a ring body, as long as it meets the usage requirements. This application does not make any specific restrictions on this, and it can be selected according to actual needs.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
