Problems solved by technology

Specifically applied to vascular tomography, since the rotation speed of the light beam is required to be very high in the vascular tomography device, this kind of catheter connector will cause wear and tear after long-term use for catheter connectors that need to be quickly selected at one end, and the connection efficiency greatly reduced

Embodiment Construction

[0017] The present invention will be described in detail below through specific examples.

[0018] An intravascular tomographic imaging catheter includes an imaging catheter body and a catheter connector connected to each other. The imaging catheter body includes a core probe and a protective sheath sheathed outside the core probe, and the core probe can be freely rotated and pushed and pulled within the protective sheath. Among them, the structure of the core probe is as follows figure 2 As shown, it includes a rigid protection tube 1, a flexible protection tube 2, a transparent packaging tube 3, and a conductive optical fiber 4 with a lens. The rigid protective tube 1, flexible protective tube 2, and transparent packaging tube 3 are connected in sequence, and the conductive optical fiber 4 with a lens is set Inside the rigid protection tube 1, the flexible protection tube 2 and the transparent packaging tube 3. The guiding optical fiber with lens focuses the light beam on...

Abstract

The invention discloses an intravascular tomography catheter. The intravascular tomography catheter comprises a tomography catheter body and a catheter connector. The tomography catheter body comprises a core probe and a protection sheath. The catheter connector comprises a first connecting unit and a second connecting unit, the first connecting unit comprises a first optical fiber connector, a first inner clamping piece and a first outer clamping piece, the second connecting unit comprises a second optical fiber connector, a second inner clamping piece and a second outer clamping piece, the first optical fiber connector and the first inner clamping piece are assembled to a whole, and the second optical fiber connector and the second inner clamping piece are assembled to a whole. When the first inner clamping piece and the second inner clamping piece are directionally clamped and finish being clamped, the first optical fiber connector is inserted into the second optical fiber connector, and the first outer clamping piece and the second outer clamping piece are clamped. The intravascular tomography catheter is connected with the catheter connector capable of locating and being connected with an optical fiber, and therefore the tomography catheter and a tomoscan instrument are connected fast, accurately and firmly.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an intravascular tomographic imaging catheter. Background technique [0002] Optical coherence tomography (OCT) technology is a new biomedical optical imaging method, which can provide high-resolution images of blood vessel cross-sections through an endoscopic imaging catheter. During use, the endoscopic imaging catheter needs to be connected with an instrument through a catheter connector. Wherein, one end of the catheter connector needs to be connected to the imaging catheter, and the other end is provided with a connecting tube connected to external medical equipment. Through the connection of the conduit connector, the signal transmission of two butted optical fibers can be realized. At present, conduit connectors are mostly tightened to fix the conduit by screwing. In actual use, the direction of tightening and compressing is very inefficient. Patent CN204107148...
