Description
Technical Field
The utility model belongs to the technical field of transurethral ureteral rubble technique and specifically relates to an intelligent control back flush constant pressure fills and attracts system.
Background
Urinary calculi can be treated by a plurality of methods, including conservative treatment, traditional open surgery and minimally invasive endoscopic surgery. With the improvement of percutaneous nephroscope and transurethral ureteroscope technologies and the upgrade of holmium laser lithotripsy equipment and perfusion platforms, the minimally invasive endoscopic surgery treatment gradually replaces the traditional open surgery mode, and gradually changes to surgery through the natural orifice of a human body, so that the application prospect is very wide.
The traditional ureteroscope water injection and drainage system shares one channel, so that continuous water circulation at the front end of the ureteroscope cannot be formed, and the lithotripsy dust interferes with the visual field in the operation, so that the lithotripsy efficiency is low; in addition, continuous water injection is easy to cause over-high renal pelvis pressure, and perfusion fluid is absorbed to cause complications such as pulmonary edema, heart failure, sepsis and the like.
Therefore, people further research a ureteroscope capable of realizing simultaneous water injection and drainage in an operation process, for example, Chinese patent CN 101879056B discloses a ureteroscope, and by additionally arranging a drainage channel, the continuous water injection through a tube cavity of a scope body in the operation is realized, and the continuous drainage of a groove on the outer wall of the scope body is realized, so that the drainage speed in the operation can be accelerated, the continuous water circulation is formed, the drainage quantity in the operation process can be increased on the premise of not influencing the operation, the clear visual field in the operation process can be kept, the operation efficiency is improved, the pressure in a renal pelvis and a ureter can be reduced, and the occurrence of postoperative bacteremia and urogenic sepsis can be prevented. However, the device cannot intelligently control the intra-cavity pressure of the perioperative renal integrated system, for this reason, chinese patent CN 103767744B discloses a medical perfusion platform, which feeds back the pressure measurement device in the cavity to the platform to automatically control the suction negative pressure, so that the intra-cavity pressure is within the safe range, thereby ensuring the safety of the operation, and the operation efficiency is improved by automatically sucking and removing stones, but a flexible ureteroscope sheath is required to be added to the platform, and water is drained through the sheath gap, thereby realizing continuous water injection and drainage and controlling the renal pelvis pressure within the safe range, and clinically about 15% -20% of patients cannot perform the primary sheath operation due to ureteral stenosis, distortion and the like, and even can cause complications such as ureteral iatrogenic injury of the patient during the sheath placement process. Therefore, transurethral ureteroscopy with a sheath has been limited in clinical practice.
