Ureteral stent imbedding auxiliary component

Abstract

The invention discloses a ureteral stent imbedding auxiliary component which comprises a white sheath and a guide sheath movably arranged in the white sheath so as to expand the ureter of a patient and further enable the white sheath to enter the ureter of the patient, an adjustable telescopic mechanism and an adjusting part are arranged in the white sheath, and a protruding part is arranged on the adjustable telescopic mechanism. Compared with the prior art, the ureteral stent imbedding auxiliary component has the advantages that when a surgeon puts in a ureteral stent, it is avoided that blood urine in the pelvis of the patient splashes on the hand after the guide sheath is taken out, the guide sheath is pulled out according to a proper path, and the adjusting part is driven to control the opening of the adjustable telescopic mechanism, so that the blood or urine is prevented from flowing out from the end part of the white sheath, the cleanness of the hands of the surgeon is ensured, and the surgical operation is better carried out; and along with gradual pushing of the white sheath into the body of the patient, an adjusting plate can be driven to be gradually unfolded, so that the blood urine flowing out from the interior of the pelvis can conveniently flow out from the protruding part.

Description

technical field [0001] The invention relates to the technical field of ureteral stents, in particular to an auxiliary component for ureteral stent placement. Background technique [0002] The ureteral stent mainly plays the role of supporting, draining, contacting the obstruction and protecting the renal function of the human ureter. It will not cause obstructive hydrops, and can relieve the patient’s symptoms of renal colic; (2) The indwelling stent can gradually expand the ureter after a period of time, making the ureter thicker and straighter, which is conducive to more flexible and rigid ureteroscopy and surgical operations. (3) Since the stent tube is impermeable to X-ray radiation, it provides a stable landmark for positioning before shock wave lithotripsy; (4) When large stones are broken, the stent can prevent a large number of stone fragments from pouring into the ureter to form a stone street, Cause ureteral obstruction and impair renal function, the stent allows ...

AI Technical Summary

Problems solved by technology

However, when the last dilator is inserted and the introducer sheath is taken out, the hematuria in the patient’s renal pelvis will splash outward due to the increase in the diameter of the tube opening, and at the same time, as the white sheath gradually penetrates into the ureter, it will Urine constantly flows out from the port of the white sheath on the outside of the body, and this port is also the port through which the surgeon uses his hand to penetrate and adjust the ureteroscope. Therefore, the splashed blood and urine are easily splashed on the surgeon’s hand , which not only affects its normal operation, but may even cause hand infection due to careless scratches on the hand during the operation, which greatly affects the normal insertion of the ureteral stent by the surgeon. Therefore, we propose a ureteral stent implantation accessories
