Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical auxiliary instrument, in particular to a special needle for pseudoaneurysm sclerotherapy. BACKGROUND

[0002] With the continuous improvement of medical level, the blood vessels minimally invasive intervention surgery of cardiovascular medicine, surgery, neurology, surgery and other departments is increasing, the minimally invasive intervention surgery is small, and the recovery is fast, and the patients benefit a lot, and it also becomes the preferred treatment method for many diseases, but at the same time, the incidence of iatrogenic pseudoaneurysm is increasing, which becomes an inevitable complication and causes harm to patients. The method for treating pseudoaneurysm can be surgical open operation, or ultrasonic guided minimally invasive intervention sclerotherapy, and the surgical open operation is traumatic, and the recovery is slow, and the patients in the recovery period are caused secondary damage. The ultrasonic guided minimally invasive intervention sclerotherapy is simple, convenient, fast, small trauma and fast recovery, and becomes the preferred treatment scheme for iatrogenic pseudoaneurysm.

[0003] At present, the ultrasonic guided pseudoaneurysm minimally invasive intervention sclerotherapy needs to inject thrombin into the pseudoaneurysm cavity after blocking the blood flow by pressing the proximal artery, and the blood in the pseudo cavity is coagulated and hardened after about half an hour, and then the proximal blood vessel is released. With the coagulation and hardening of the pseudoaneurysm cavity, the channel between the pseudoaneurysm cavity and the artery is blocked, and the treatment is completed. At present, the blood flow of the artery is mainly blocked by artificial compression of the proximal artery. The pressure of the arterial blood vessel is large, and there is certain difficulty in blocking the blood flow by artificial compression of the blood vessel. Moreover, the compression position and the ultrasonic probe position are often overlapped, which is inconvenient to operate. Two clinical doctors often rotate to press, and an ultrasonic intervention doctor and an assistant observe the puncture and drug injection, and the failure is prone to occur. It is time-consuming and laborious, and the forced compression also brings pain and discomfort to the patient, which is often intolerable, leading to poor practicability. Therefore, a special needle for pseudoaneurysm sclerotherapy is needed to improve the above problems. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the above technical problems, the utility model provides a kind of special needle for pseudoaneurysm sclerotherapy, which is installed on support structure, then needle core one is inserted into support structure, then one end of needle core one is stretched out with one end of support structure, then needle core one and support structure are inserted into patient's body, and needle core one is extracted, then support structure is used to support plugging structure, so that plugging structure is unfolded, and proximal blood vessel of pseudoaneurysm is blocked, then doctor injects thrombin into pseudoaneurysm, so as to improve the practicability of special needle for pseudoaneurysm sclerotherapy.

[0005] The utility model discloses a kind of special needle for pseudoaneurysm sclerotherapy, including needle core one;Still including support structure and plugging structure, support structure is installed on needle core one, plugging structure is installed on support structure;

[0006] The needle core one penetrates into the patient's body, and the supporting structure cooperates with the blocking structure to block the proximal blood vessels of the false aneurysm;

[0007] The blocking structure is installed on the supporting structure, and then the needle core one is inserted into the supporting structure. Then, one end of the needle core one protrudes from one end of the supporting structure. Then, the needle core one and the supporting structure are penetrated into the patient's body, and the needle core one is extracted. Then, the blocking structure is supported by the supporting structure, so that the blocking structure is unfolded to block the proximal blood vessels of the false aneurysm. Then, the doctor injects thrombin into the false aneurysm, thereby improving the practicability of the special needle for hardening treatment of false aneurysm.

[0008] Preferably, the supporting structure comprises a needle sleeve and a needle core two, the needle sleeve is sleeved on the needle core two, one end of the needle core two is provided with a hollow cage type ball structure, and the needle core one is inserted into the needle core two. The blocking structure is wrapped on the hollow cage type ball structure, and then the needle core two is inserted into the needle sleeve. The hollow cage type ball structure on the needle core two is bound by the needle sleeve. After the needle core one penetrates into the patient's body and reaches the designated position, the needle core one is extracted from the needle core two. Then, the needle sleeve is pulled out of the patient's body, so that the hollow cage type ball structure on the needle core two is separated from the binding of the needle sleeve. Then, the hollow cage type ball structure unfolds the blocking structure to block the proximal blood vessels of the false aneurysm, thereby improving the practicability of the special needle for hardening treatment of false aneurysm.

[0009] Preferably, the blocking structure comprises a gasket, the gasket is wrapped on the hollow cage type ball structure of the needle core two, and the middle part of the gasket is provided with a cross-shaped cut; when the special needle for hardening treatment of false aneurysm is assembled, one end of the needle core one passes through the cross-shaped cut in the middle part of the gasket. After the needle core one penetrates into the patient's body and reaches the designated position, the needle core one is extracted, and the cross-shaped cut on the gasket is closed. Since the cross-shaped cut is cross-shaped and the blood is relatively viscous, the blood is difficult to pass through the cross-shaped cut. When the hollow cage type ball structure is unfolded, the gasket is supported up to block the proximal blood vessels of the false aneurysm, thereby improving the practicability of the special needle for hardening treatment of false aneurysm.

[0010] Preferably, the gasket is made of dissolvable material; after the operation is completed, the gasket does not need to be taken out and is dissolved in the patient's body, thereby improving the practicability of the special needle for hardening treatment of false aneurysm.

[0011] Preferably, one end of the needle core one is a sharp inclined plane; it is convenient to penetrate into the patient's body with the needle sleeve and the needle core two, thereby improving the practicability of the special needle for hardening treatment of false aneurysm.

[0012] Preferably, the other end of the needle core one is provided with a handle; it is convenient for the doctor to hold the handle and extract the needle core one from the needle core two, thereby improving the practicability of the special needle for hardening treatment of false aneurysm.

[0013] Preferably, the hollow cage type ball structure on the second needle core is elastic; the hollow cage type ball structure on the second needle core automatically expands when not constrained, thereby improving the practicality of the special needle for pseudoaneurysm sclerotherapy.

[0014] Compared with the prior art, the utility model has the beneficial effects that the plugging structure is installed on the support structure, then the first needle core is inserted into the support structure, then one end of the first needle core protrudes from one end of the support structure, then the first needle core and the support structure are stabbed into the patient's body, then the first needle core is pulled out, then the plugging structure is supported by the support structure, the plugging structure is expanded, the proximal blood vessel of the pseudoaneurysm is blocked, then the doctor injects thrombin into the pseudoaneurysm, thereby improving the practicality of the special needle for pseudoaneurysm sclerotherapy.
