Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0016] Such as figure 1 shown.
[0017] An OCT conduit air flow welding tool, which includes a hot air blower 1, the air flow generated by the hot air blower 1 enters the air flow controller 2, and the air flow controller 2 enters the air flow generated by the hot air blower into the three-way air pipe joint 3, and the three-way air pipe joint One of the 3 is connected to the heater 4. After being heated in the heater 4, it enters the heating pipe 5. The heating pipe 5 heats the heating tank 6. The heating tank 6 is composed of upper and lower parts, and the upper and lower parts are controlled by pneumatic or electric. Opening and closing (not shown in the figure, the opening and closing structure is a conventional structure, which can be designed according to needs). A conduit clamping block 7 is installed at both ends of the heating tank 6, and the...

The invention relates to an OCT (optical coherence tomography) catheter airflow welding tool. The welding tool comprises an air heater and is characterized in that airflow generated by the air heaterenters an airflow controller; the airflow controller feeds the airflow into a tee air pipe joint; one way of the tee air pipe joint is connected with a heater; the airflow enters a heating pipe afterbeing heated in the heater, and the heating pipe heats a heating groove; a catheter clamping block is installed at each of two ends of the heating groove, and a catheter is clamped in the heating groove by the catheter clamping blocks; the heating pipe is covered with a cooling block; other two ways of airflow in the tee air pipe joint enter an installation space of the cooling block via the air pipe joint, enter the cooling block from the lower part of the cooling block, and flow out of cooling holes in the cooling block to cool the heating pipe and prevent the temperature from being too high. The welding tool takes safety protection into account, and accurately controls the heating airflow and heating time, thereby improving welding safety and stability of catheters and improving production efficiency and product consistency.
Description
technical field [0001] The invention relates to a tooling fixture for manufacturing medical equipment, in particular to an OCT catheter manufacturing tool, in particular to an OCT catheter gas flow welding tool. Background technique [0002] At present, the intravascular tomographic imaging system and imaging catheter are designed to image blood vessels with a diameter > 1.5 mm, to achieve accurate measurement of lumen diameter and area, to image the vessel wall and intravascular implant structure, and to identify plaques. Block properties and evaluation for endovascular implants (stents, filters, coils, etc.). [0003] The intravascular tomography system is a system based on intravascular optical coherence tomography (OCT) technology combined with an imaging catheter. OCT technology is a new intracoronary imaging technology following intravascular ultrasound (Intravascular Ultrasound, IVUS) Compared with IVUS, the extremely high resolution of OCT has attracted increasin...
