Embodiment 1

[0034] Such as Figure 1~Figure 5 As shown, a detachable intravascular imaging catheter is connected to the connection port 1. The detachable intravascular imaging catheter includes an imaging inner core 2, an outer sheath 3 and a locking head 4. The outer sheath 3 includes an outer The protective tube 5 and the three-way tube 6, the outer protective tube 5 and the three-way tube 6 are connected, and the outer protective tube 5 includes a proximal area 51 close to the connection port 1 and a part far away from the connection port 1 for guiding into blood vessels. The distal region 52, the proximal region 51 is provided with an imaging lumen, one end of the imaging core 2 is connected to the connection port 1, and the other end of the imaging core 2 is inserted into the imaging tube through the locking head 4 In the lumen; one end of the locking head 4 is connected to the connection port 1, and the other end of the locking head 4 is detachably connected to the outer sheath 3; t...

Embodiment 2

[0039] A diagnostic system such as Figure 6 As shown, it includes a detachable intravascular imaging catheter as described in Embodiment 1, a connection port, a connection unit and a control unit, and the connection port is connected to the imaging unit of the detachable intravascular imaging catheter described in Embodiment 1 and the connection unit, and send the imaging of the target tissue by the imaging unit to the control unit through the connection unit, and the control unit receives, processes and displays the image information.

Abstract

The invention provides a detachable intravascular imaging catheter and a diagnosis system. The detachable intravascular imaging catheter is connected with a connecting port, and includes an imaging core, a sheath, and a locking head. The sheath comprises an outer protecting pipe. The outer protecting pipe includes a near side region close to the connecting port, and a far side region which is faraway from the connecting port and used to guide into a blood vessel. The near side region is internally provided with an imaging pipe cavity. One end of the imaging core is connected with the connecting port, and the other end of the imaging core passes through the locking head and is embedded in the imaging pipe cavity. One end of the locking head is connected with the connecting port, and the other end of the locking head is detachably connected with the sheath. Using the technical scheme realizes detachable connection of the imaging core and the sheath. The sheath is changed after being used every time, and the imaging core does not need complex cleaning and disinfection and can be reused, so product cost is reduced. The detachable intravascular imaging catheter and the system are simple in operation, and are beneficial for industrialized popularization.

Description

technical field [0001] The invention belongs to the technical field of intravascular imaging, in particular to a detachable intravascular imaging catheter diagnosis system. Background technique [0002] Coronary heart disease is the most common heart disease, which refers to myocardial dysfunction and (or) organic disease caused by coronary artery stenosis and insufficient blood supply, so it is also called ischemic cardiomyopathy. It is one of the diseases with the highest mortality rate in the world. According to the report of the World Health Organization in 2011, the number of deaths from coronary heart disease in China has ranked second in the world. At present, for the diagnosis and treatment of such diseases, more mature methods are used clinically, including coronary angiography and intravascular catheter imaging. Coronary angiography can only obtain two-dimensional image information of blood vessels, and most of the lesions occur inside the blood vessels; in additi...
