Embodiment Construction

[0022] The present invention will be further described below in conjunction with examples, but the present invention is not limited to these examples.

[0023] The water-lubricating composite balloon ureteral dilator described in this embodiment, as attached figure 1 As shown, a dilator body 10 with a circumference of 8 mm is included, and three channels are opened inside the dilator body 10 . The channel located at the central axis of the dilator body 10 and passing through the dilator body 10 is the guide wire channel 11 , which can accommodate the passage of the zebra guide wire. The other two channels are the balloon channel 12 , the anterior capsule channel 121 and the posterior capsule channel 123 .

[0024] The dilator body 10 is provided with two dilation balloons 13 arranged at intervals, which are respectively a front dilation balloon 131 and a rear dilation balloon 133. The front dilation balloon 131 is close to the front end of the dilator body 10, and the rear di...

Abstract

The invention provides a water-lubricating composite balloon ureteral dilator. The water-lubricating composite balloon ureteral dilator comprises a dilator body which is provided with at least three passageways, a guide wire passageway is positioned on the central axis of the dilator body and penetrates through the dilator body. The other passageways are balloon passageways, each balloon passageway is communicated with a corresponding dilation balloon, and the dilation balloons are shrinkable circumferentially and arranged in the axial direction of the dilator body at equal intervals. The water-lubricating composite balloon ureteral dilator has the advantages that by the aid of the guide wire passageway which allows a guide wire to pass through, insertion of the dilator is more convenient; by the aids of the dilation balloons and the corresponding balloon passageways, different parts of a ureter can be dilated and dilation degrees can be controlled according to needs; by adopting the ureteral dilator coated with a hydrophilic film, the cost for aseptic paraffin oil is reduced, operation is simplified, and postoperative secondary infections and pains of patients can be reduced by antibiotic constituents in the film. The water-lubricating composite balloon ureteral dilator can be specifically applied to common narrow parts like a ureteral orifice, the junction of a ureter and an iliac vessel and the like, and dilation diameters can be controlled by means of controlling the sizes of the dilation balloons.

Description

technical field [0001] The invention relates to the technical field of urethral dilators, in particular to a water-lubricating composite balloon ureteral dilator that does not need to be coated with lubricant. Background technique [0002] The incidence of upper urinary tract stones and tumors is increasing year by year. When performing invasive examination and surgical treatment, it is usually necessary to insert a ureteroscope into the ureter and renal pelvis. In the process of clinical application, it is often encountered that due to the narrow lumen of the ureter, it is difficult for the mirror body of the ureteroscope to enter, and even lead to serious complications such as ureteral rupture, avulsion, and mirror body incarceration. At present, pre-installed D-J tubes are usually used for dilation for 2 to 4 weeks, and / or an introduction sheath is used to dilate and protect the mirror body during the operation to reduce the incidence of inability to enter the mirror, esp...
