Effective angle regulation's ureter stand pipe

Technical Field

The utility model belongs to the field of medical equipment, a ureter stand pipe in uropoiesis surgery diagnosis and treatment is related to, concretely relates to effective angle regulation's ureter stand pipe.

Background

Cystoscope and ureteroscope operations are one of the minimally invasive treatment means widely developed by urology surgery in recent years, have the advantages of small operation wound, short operation course, simple operation and the like, and have important diagnosis and treatment values for diseases related to urinary excretion systems such as bladder, urethra, ureter and the like. With the continuous development of endoscope technology, the outpatient ureteroscope operation is more and more common in clinic, but because the ureteroscope operation is an invasive operation, a metal sheath with the circumference of 1.7-2.3 cm needs to be placed into a ureter through a urethral orifice and a bladder, and because the opening of the ureter is horizontal, the opening of the ureter is mostly vertical to the outlet of the urethra at the bladder instead of being right, the problem that a guide wire cannot effectively enter the ureter when the ureteroscope enters the ureter through the bladder for examination is caused; in addition, the observation visual field is limited in the operation process, blind spots exist, and symptoms such as pain, hematuria, urethral burning pain and the like are easy to appear after the operation. For male patients, due to the complicated structure of the urethra, two physiological curvatures, the posterior urethra with the triangular ligament and the prostate gland fixed, pain and bleeding are caused by the friction of the sheath against the urethra during examination. Meanwhile, perineum muscle contraction is generated due to pain of a patient, so that the examination difficulty is increased, the examination time is prolonged, and the injury is aggravated, so that pain and hematuria of part of patients can still occur within 12-48 hours after examination, pain and discomfort are brought to the patient, and the serious patient can induce cardiovascular and cerebrovascular accidents.

The ureter guide tube is a hard plastic catheter, and when the ureteroscope operation is carried out, an operating doctor can distinguish the running of the ureter by means of the supporting effect of the ureter guide tube, so that stenosis is broken through, a guide wire accurately enters the ureter, and the damage to the ureter is avoided. The ureter guide tube is used in the ureteroscope operation, so that the operation success rate can be improved, the operation complications can be reduced, and the pain of a patient can be reduced.

When examining the ureter through ureteroscope operation among the prior art, the ureter opening is often horizontal to, and its direction is many perpendicular at the export of bladder with the urethra, and is just right, when leading to getting into ureter inspection through the bladder, there is the seal wire can not effectively get into the ureter, and then the unable problem of effectively getting into and carrying out the inspection of ureteroscope, the utility model relates to an effective angle regulation's ureter stand pipe accomplishes the guide of seal wire direction, and has set up specific pipe diameter, the angle of turning and the shape of turning to make the seal wire can find the ureter mouth of pipe fast, be convenient for introduce ureteroscope inspection, through the introduction of the ureter stand pipe that can effective angle regulation, make ureteroscope get into ureteroscope inspection and become smooth and easy.

The ureteroscope guide tube designed by the utility model can keep the ureteroscope with good operation visual field in the ureteroscope operation, so that the guide wire can quickly and accurately find the ureteroscope opening to ensure the smooth operation of the ureteroscope operation, and reduce the pain of patients; the manufacturing method is simple, has low requirements on equipment and consumables, and has good market application prospect.
