Problems solved by technology

In domestic clinical nephrostomy operations, blind puncture is generally used, and the control of puncture depth depends entirely on the doctor's clinical grasp. There is no accurate measurement of the depth of penetration into the kidney, and there are certain safety hazards

Embodiment Construction

[0012] This combined ostomy tube as shown in the figure is a creative improvement to the various existing ostomy tubes with the same function of expansion and hemostasis.

[0013] This combined ostomy tube includes a Y-shaped connecting part 5 forming a balloon catheter, an outer catheter 1 connected to the Y-shaped connecting part 5, a balloon inner tube 3, and a balloon 2 arranged on the balloon inner tube. The outer catheter 1, the balloon inner tube 3, and the balloon 2 are threaded together to form the main body of the balloon catheter, and the sheath tube 4 and the balloon dilation catheter are concentrically threaded to form an ostomy tube, which is characterized in that: the balloon dilation The inner tube scale line 6 and the sheath tube scale line 7 are respectively on the balloon inner tube 3 and the sheath tube 4 of the catheter.

[0014] The outer surface of the inner tube of the balloon inner tube 3 is marked with a scale every 1cm from the distal end, each scale...

Abstract

The invention relates to a combined fistulization catheter. The fistulization catheter comprises a Y-type connecting component (5), an outer catheter (1) connected to the Y-type connecting component (5), a balloon inner tube (3) and a balloon (2) arranged on the balloon inner tube, wherein a balloon catheter is formed by the Y-type connecting component (5), the outer catheter (1), the balloon inner tube (3) and the balloon (2), a body of the balloon catheter is composed of the outer catheter (1), the balloon inner tube (3) and the balloon (2) which are arranged together in a sleeved mode, and the balloon dilating catheter is concentrically sleeved with a sheath tube (4) to form the fistulization catheter. The fistulization catheter is characterized in that the balloon inner tube (3) and the sheath tube (4) of the balloon dilating catheter are provided with scale marks. In the clinical application, the fistulization catheter facilitates surgical operation of a doctor in the nephrostomy puncture process, and the depth by which the fistulization catheter is actually inserted into the kidney can be learned through display scales at the tail end, outside the body, of the fistulization catheter after the fistulization catheter is inserted into the kidney of a patient.

Description

technical field [0001] The invention relates to a device for urinary system operation, in particular to a combined fistula tube, which is suitable for clinical nephrostomy operation. Background technique [0002] In clinical nephrostomy, the method of step-by-step dilation is generally adopted to establish the channel, which is cumbersome to operate and the effect is not ideal. In order to improve the efficiency and achieve the ideal surgical effect, the method of balloon expansion and sheath was used to establish the fistula channel at one time. In domestic clinics, nephrostomy operations are generally performed blindly, and the control of the puncture depth depends entirely on the doctor's clinical control. There is no accurate measurement of the depth of the nephrostomy, and there are certain safety hazards. Contents of the invention [0003] The purpose of the present invention is to provide a composite fistula tube for accurately measuring and displaying the puncture...
