Problems solved by technology

The problem with the above-mentioned intravascular balloon catheter is that the downstream of the blocking site cannot supply blood at all, thus causing organ ischemia downstream of the blocking and affecting the success of the operation
However, the problem with the double-balloon intravascular catheter of this structure is that when there are important organs and blood vessels on one or both sides of the diseased blood vessel, the artery cannot be blocked in sections, and the blood supply to the important organs is first performed after the diseased blood vessel is removed. Shorten the ischemic time of vital organs

Embodiment 1

[0022] The structure of the multi-balloon intravascular catheter in this embodiment is shown in Figure 1. One end of the tube body 1 is open, and the other end is equipped with a fixing sleeve 6. At the end close to the tube body opening, the outer wall of the tube body is coated and fixed with The first balloon 2, the second balloon 3, the third balloon 5, and the balloon air delivery tube 7 are three at a certain distance, inserted into the inner cavity of the tube body 1 through the fixing sleeve 6 and respectively connected to the corresponding inner cavity of the balloon. communicated; there are two side holes 4, which are opened between the second balloon 3 and the third balloon 5, and there is no side hole between the first balloon 2 and the second balloon 3; there is one blood vessel 8, It is inserted into the inner cavity of the tube body 1 through the fixing sleeve 6 and communicates with the holes 4 on both sides and the opening of the tube body 1 . Tube body 1, fix...

Embodiment 2

[0027] The structure of the multi-balloon intravascular catheter in this embodiment is shown in FIG. 2 . The difference from Embodiment 1 is that there is only one side hole 4 opened between the second balloon 3 and the third balloon 5 . The method of using the multi-balloon intravascular catheter with this structure is the same as that in Example 1.

Embodiment 3

[0029] The structure of the multi-balloon intravascular catheter in this embodiment is shown in Figure 3, and the difference from Embodiment 1 is that the side hole 4 is opened between the first balloon 2 and the second balloon 3 and the third balloon Between the balloon 5 and the fixed sleeve 6 and close to the third balloon, there is one side hole at both places, and there is no side hole between the second balloon 3 and the third balloon 5; the blood transfusion tube 8 is equipped with a stylet 9 , The stylet and the blood vessel are combined in a push-and-pull manner.

[0030] The multi-balloon intravascular catheter of this structure is also suitable for the operation of cardiovascular aneurysm involving the renal artery, and the usage method is as follows: insert the catheter from above, inflate the third balloon 5, and block the artery. The surgeon cuts off the diseased blood vessel, puts the artificial blood vessel outside the catheter, and first anastomoses the bilate...

Abstract

A vascular endocatheter with multiple spherical bags for segmentally blocking the blood vessel in lesion for cutting it off and then quickly restoring the blood supply to organs is composed of a tube bodywith an open end and a fixing sleeve at its another end and at least three spherical bags fixed to the external surface of tube body. Said external surface of tube body has lateral holes. The gas delivering tube or perfusion tube is inserted in the tube body via said fixing sleeve and communicated with the internal cavities of said spherical bags.

Description

technical field [0001] The invention belongs to medical equipment, in particular to an intravascular catheter with a balloon for vascular surgery. Background technique [0002] During surgery, in order to facilitate the operation, it is necessary to temporarily block the artery or vein. The medical device currently used is an intravascular balloon catheter, and its structure is to install one or two balloons at the open end of the catheter tube. , from the other end of the catheter tube, insert the trachea and blood vessel (also known as the lumen), which are respectively connected to the inner cavity of each balloon and the opening of the catheter tube, and block the artery or vein by intermittently filling the balloon blood flow. The arterial intravascular balloon catheter disclosed in Chinese patent ZL 02113689.0 adds a side hole on the catheter tube body and a delivery tube (also known as a lumen) that only communicates with the side hole on the basis of the above struc...
