Abstract

The invention provides a reinforcing tube for a flexible cryoprobe and the flexible cryoprobe. The reinforcing tube comprises an outer layer tube, an inner layer tube, a metal wire and a wire groove,wherein the wire groove is formed in the outer wall of the inner layer tube, the metal wire is embedded in the wire groove, and the outer layer tube is arranged on the outer side of the inner layer tube in a sleeving manner; and the metal wire can fully compensate pressure resistance of a catheter, possibility is provided for further reducing the diameter of the catheter, and the wire groove can sufficiently fix the metal wire to prevent the metal wire from shifting. Therefore, the pressure resistance of the catheter can be compensated when the diameter of the catheter is reduced.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to a reinforcing tube for a flexible cryoprobe and a flexible cryoprobe. Background technique [0002] The flexible cryoprobe can be bent through the natural cavity of the human body to reach the lesion for cryotherapy. For blood vessels, bronchi and other multi-branched natural cavity from thick to thin, the smaller the diameter, the larger and farther the treatment area can be covered , therefore, the diameter reduction of needles and flexible catheters is the core development trend of flexible cryoprobes. [0003] In the prior art, the thinning of the flexible catheter can only be achieved by reducing the wall thickness of the flexible catheter. However, reducing the wall thickness will inevitably lead to a decrease in the pressure resistance performance, which will bring safety risks to the operation. It can be seen that the wall thickness and pressure resistance cann...
