Technical Field
The utility model relates to a medical equipment relates to a method is diagnose to flexible ureteroscope of integrated guide sheath, the utility model discloses an adopt this method to realize the medical device that integrates that flexible ureteroscope diagnoses.
Background
The ureter soft lens is usually used in urinary tract and renal examination and urinary tract lithotripsy operation, and is a thin lens with a diameter of about 3mm, which enters into the kidney through the urethra, bladder and ureter, and the ureter calculus or kidney calculus is broken up and taken out by using a laser fiber or other tools in a working channel of the ureter soft lens. It utilizes the natural cavity of human urinary system, does not make any incision on the body, and is a urinary surgery endoscopic non-invasive or minimally invasive operation. Compared with open surgery, ureteroscope lithotripsy has the advantages of small injury, light pain, quick recovery and the like. Soft-lens surgery, however, requires a high level of manipulation by the surgeon.
The existing ureter soft lens needs a plurality of steps to finish when entering a urinary system:
step 2: using a cystoscope to find an inlet of a left ureter or a right ureter in a bladder cavity, and leading a guide wire to enter the left ureter or the right ureter through a working channel of the cystoscope;
step 4, extracting the guide wire and the guide sheath inner core;
step 5, extending the flexible ureteroscope out of the head of the guide sheath along the inner cavity of the guide sheath to enter the ureter and the kidney;
step 6, using a ureter soft lens to search and determine the position of the calculus, and extending a laser fiber into a working channel of the ureter soft lens to perform calculus breaking operation or extending a calculus taking basket into the working channel to perform calculus taking operation; repeating the step 4 and the step 5 until the steps are finished;
after the operation is finished, the flexible ureteroscope is withdrawn from the human body along the guide sheath, and then the guide sheath is withdrawn from the human body.
In the above-mentioned operation, an additional cystoscope is needed in order to guide the wire to find the entrance of the left ureter or the entrance of the right ureter. Thus, the cost and time of using the cystoscope is increased. However, if a cystoscope is not used, the time for finding the entrance of the left ureter and the right ureter is increased during the insertion process of the guide wire, and the risk that the guide wire punctures the inner wall of the urinary system is increased.

and 6, step 6: the guide wire is drawn out from the working channel of the ureter soft lens and exits from the human body;
and 7, step 7: the position of the calculus is searched and determined by using a ureter soft lens, and the calculus is broken by extending a working channel of the ureter soft lens into a laser fiber or extending into a calculus extraction basket to perform calculus extraction.
The flexible ureteroscope integrated with the guide sheath by adopting the method is characterized in that: it comprises a guide sheath, a fixing part, a detachable hard tube and a ureter soft lens; the fixing part is arranged at the tail part of the guide sheath; the detachable hard tube tail is provided with a conical sleeve hole, and the conical sleeve hole is fixedly connected with a handle of the ureter soft lens.
The detachable hard tube comprises an upper guide sheath connector and a lower guide sheath connector which can be mutually buckled.
An elastic buckle is arranged on the upper guide sheath connector and can be matched with a bayonet in the fixing part.
Compared with the prior art, the invention adopts the mode of combining the guide sheath with the soft ureteroscope to replace the original method of respectively inserting the cystoscope, the guide wire, the guide sheath and the soft ureteroscope into the urinary system, directly and conveniently leads the guide sheath fixedly connected with the soft ureteroscope into the urethra, the bladder and the ureter at one time without using the cystoscope, simplifies the operation steps, saves the operation time, reduces the operation cost and reduces the operation risk.
The detachable hard tube can combine the flexible ureteroscope handle and the tail end fixing part of the guide sheath into a whole in the process of inserting the guide sheath into the urethra, and the insertion operation of the guide sheath can be conveniently realized by pushing the flexible ureteroscope handle. When the soft ureteroscope is required to further go deep into a ureter from a bladder, and the like, the detachable tube is directly separated, and when the fixed part is positioned at the entrance of the urethra, the soft ureteroscope can obtain a proper flexible pushing distance by pushing the handle of the soft ureteroscope, so that the deep inspection of the soft ureteroscope is facilitated.
