Problems solved by technology
If it is found that the inserted catheter is not suitable during the operation, it is necessary to replace the catheter with another type of the same type, and replace the whole set of catheter (including the twist control section of the catheter and the front end of the catheter), which will not only delay the operation time, but also increase the medical cost and surgical risk.

Embodiment Construction
[0029] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.
[0030] In this embodiment, a Judkins type interventional catheter is taken as an example for illustration.
[0031] figure 1 and figure 2 As shown, a detachable combined interventional catheter is classified as Judkins interventional catheter, including only one model (straight tube) of the catheter twist control section and different models (corresponding to different shapes or sizes of arteries and coronary arteries) front end. The catheter twist section can be well connected with different types of catheter front ends to form a complete interventional catheter. A sheath is set at the connecting end of the catheter twist control section, and the connecting end of the curved catheter front end can be inserted into the sheath tube. The segment and the front end of the catheter are tightly combined into a whole. During the intervention...

The invention relates to a detachable combined intervention catheter and belongs to the technical field of medical apparatuses. The intervention catheter comprises a catheter torsion control section and a curved catheter front end which are connected detachably, and the interiors of the catheter torsion control section and the curved catheter front end are communicated after the connection. The two sections of the catheter can be combined according to different requirements of patient operations, and accordingly, the requirement of catheter intervention is achieved. The invention further relates to an assembly method of the detachable combined intervention catheter. Compared with the prior art, the intervention catheter and the assembly method have the advantages that the process is simple, the production efficiency is high, the catheter selection efficiency during the interventional operation is well improved, the catheter front end can be changed rapidly when that the catheter model is wrong is discovered during the operation, the medical cost can be greatly reduced, and the detachable combined intervention catheter is widely applicable to the medical industry.
Description
technical field [0001] The invention relates to a medical device for coronary intervention, in particular to a catheter for coronary intervention and an assembly method thereof. Background technique [0002] Interventional surgery is an emerging medical technology that uses interventional catheters to pass through the lumen of blood vessels to achieve low-invasive diagnosis and treatment of lesions. Compared with traditional medical technology, interventional therapy has the following advantages: easy to operate; due to the low trauma of interventional therapy, it can avoid causing great pain to patients; because of its minimally invasiveness, it can reach parts that cannot be reached by conventional surgery; The cost of conventional surgical treatment is also relatively low, so it is widely accepted by patients and doctors. Now interventional therapy technology has been widely used clinically in cardiovascular and cerebrovascular angiography and stenotic angioplasty. [0...
