Technical Field
The invention relates to the technical field of medical instruments, in particular to a soft lens introducing device and a using method thereof.
Background
With the popularization of minimally invasive surgery, various flexible mirrors with bendable heads are used in various surgeries, so that the pain of patients is reduced. Most of the soft lenses can be inserted to the corresponding examination or operation position in one step, but the soft ureteroscope, the soft bladder speculum, the soft renal pelvis speculum, the soft intestinal tract speculum, the soft digestive system speculum and the like still have the problem of difficult insertion to the preset position in the body. For example, since the soft ureteroscope, the soft bladder speculum, the soft renal pelvis speculum and the like are required to be inserted from the urethral orifice of a human body, and the soft ureteroscope, the soft bladder speculum and the soft renal pelvis speculum must be placed at a preset position in the body through a plurality of steps of operation due to the stenosis and sensitivity of the urethra, so that the operation steps of a doctor are increased, the working efficiency is low, the operation cost is high, the operation time is long, and the body and mind of a patient are painful.
Specifically, for example, the conventional uretero-pyeloscope requires repeated operations to place the soft scope in place from the urethra of the human body: the method comprises the steps of firstly inserting a ureteroscope with a lens into a urethra of a human body to pass through a channel to find a preset position, secondly inserting a zebra guide wire into the position of a renal pelvis through a working channel of the ureteroscope (the preset position can be observed through a display screen), thirdly withdrawing the ureteroscope while the zebra guide wire is kept at the position of the renal pelvis until the ureteroscope is completely withdrawn, fourthly advancing a ureter introducing sheath assembly with a fine round head to the position of the renal pelvis along the zebra guide wire (no lens monitoring exists at the time, the blind insertion is realized), fifthly pulling out a guide sheath in the ureter introducing sheath assembly, simultaneously pulling out the zebra guide wire, keeping the ureter introducing sheath in the human body, and sixthly inserting the flexible endoscope into the position of the renal pelvis along the ureter introducing sheath. Therefore, the operation steps of doctors and the damage degree of the body of a patient are greatly increased, the operation time is long, the operation is complex, the working efficiency is low, the stability and the reliability of the operation are low, the number of surgical instruments is large, and the operation cost is high.
