Binary channels ureteroscope that possesses temperature measurement pressure measurement functionTechnical Field
The utility model relates to the technical field of medical equipment, in particular to a dual-channel ureteroscope with a temperature and pressure measuring function.
Background
Ureteroscope is one of the most important and most commonly used medical instruments in urology surgery, and is widely applied to the examination and treatment of diseases such as upper urinary tract stones. In order to relieve the pain of patients and reduce the trauma of operations, the uretero-nephroscope is objectively required to have the smallest diameter of the endoscope body, and in order to facilitate the operation of doctors, the diameter of a working channel in the endoscope body is required to be as large as possible, and the working channel is limited by the manufacturing process, so that most of the traditional uretero-nephroscopes have only one working cavity.
However, in ureteroscopic procedures, it is often necessary to continuously inject a rinsing fluid into the surgical site through the working channel of the body in order to maintain a clear field of view. Along with the operation, the flushing liquid poured into the operation part can become turbid gradually due to bleeding or broken stone, the visual field definition is affected, the water injection is stopped, turbid water is discharged, clean water is refilled after the sewage is discharged, and the operation party can continue.
Therefore, the ureteroscope which can only perform water injection and drainage through the same cavity inevitably has the following defects:
(1) Because the water injection and the water drainage can only be operated separately, water circulation cannot be formed, so that the visual field is often unclear in the operation process, the operation of separate water injection and water drainage can also influence the operation efficiency, and the operation time is prolonged;
(2) At present, the perfusion is mostly realized by a manual push injection syringe or a medical perfusion pump, the continuous water injection ensures that the internal pressure of the anterior end of the endoscope and the kidney is too high, and when the internal pressure of the kidney is too high, urine flows back, various components and bacteria in the urine are easy to be absorbed into blood, so that postoperative fever and even systemic infection are caused;
(3) Early identification and timely management of high intra-renal pelvis pressure is critical in preventing such high mortality complications. The common ureteroscope does not have a self-contained pressure measuring function, and the pressure measurement in the renal pelvis commonly used in clinic is usually realized through a renal puncture catheter or a ureteral retrograde intubation, so that the placed pressure measuring tube and a specific part of an operation are often not positioned at the same position, the pressure measurement is not accurate enough, and the pressure in a renal collecting system cannot be reflected in real time;
(4) At present, holmium laser or thulium laser lithotripter is used for lithotripter, the liquid temperature in the ureter is overhigh for a long time, the local temperature is overhigh, the thermal injury of human tissues is possibly caused, and complications such as necrosis can even appear when serious;
(5) Early identification and timely stopping of laser lithotripsy, and continuous water flow temperature reduction are key. The common ureteroscope has no self-contained temperature measuring function.
In summary, the prior art has the defects that water cannot be injected and drained simultaneously in the existing ureteral nephroscopy or operation process, the technical problems of difficult accurate and real-time monitoring of the pressure and temperature in the ureter are solved, and the safety of the operation is easily influenced.
