Cystoscope sheath integrated flexible ureteroscope

Abstract

The invention discloses a cystoscope sheath integrated flexible ureteroscope, and belongs to the technical field of medical instruments. The cystoscope sheath integrated flexible ureteroscope comprises a flexible cystoscope sheath, an operating handle and a flexible ureteroscope main body, wherein the front end of the flexible ureteroscope main body is a front bending part which has a degree of bending freedom; an adjusting handle is arranged on the operating handle; the front end of the flexible ureteroscope main body passes through the side wall of the rear end of the flexible cystoscope sheath; an instrument arranged at the front end of the flexible ureteroscope main body, an outlet end of a water inlet channel and the front end face of a camera are flushed with the front end face of the front bending part; the flexible ureteroscope also comprises an inner core which is spliced with the flexible cystoscope sheath and a negative pressure connection device, the splicing is a detachable connection way, and the negative pressure connection device and the rear end of the flexible cystoscope sheath can detachably connected and is used for clearing away crushed stones. According to thecystoscope sheath integrated flexible ureteroscope disclosed by the invention, the effects of flushing water, crushing stones, attracting and clearing away the stones can be achieved, the working efficiency for crushing and clearing away the stones is improved, the pain of patients is alleviated, injury of ureter is effectively avoided, the treatment time can be shortened, and the medical treatment expenses of the patients are reduced.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a flexible ureteroscope, in particular to a flexible ureteroscope integrated with a mirror sheath. Background technique [0002] Urinary calculus is a disease with a high incidence and can seriously affect people's health, and it can even lead to loss of kidney function due to obstruction of hydrops. Therefore, urinary stones need active treatment. At present, minimally invasive surgery has been adopted in the treatment of stones in urology, and transurethral lithotripsy is widely used in the treatment of urinary stones because it has no surgical incision and is more minimally invasive. Flexible ureteroscope, because it can be bent at the head end to reach the calices of each calices of the kidney, makes up for the inadequacy that rigid ureteroscopes cannot crush stones in the middle and lower calices of the kidney. Therefore, flexible ureteroscopes are currently used ...

AI Technical Summary

Problems solved by technology

There are the following deficiencies: ① often the fluid outflow is not smooth enough, resulting in a lot of fluid influx, resulting in an increase in the pressure in the renal pelvis, which can easily lead to serious consequences; ② the biggest problem after flexible ureteroscopy is that the crushed stones cannot be cleaned out However, patients need to undergo follow-up stone removal treatment to gradually discharge the crushed stones by themselves. If they cannot be discharged, residual stones will form, requiring a second operation or causing recurrence of stones.

Although a soft mirror sheath that can attract clear stones has been invented on the market, the current soft mirror sheath cannot be bent, and the mirror sheath is still separated. There is a certain distance between the soft mirror gravel and the crushed stone, and the crushed stone cannot be directly attracted to clear the stone, and the stone clearing cannot be fully effective

The soft mirror itself must pass through the soft mirror sheath to provide vision and flushing water, so that it can be attracted. In this way, the soft mirror body occupies most of the channel space of the soft mirror sheath that attracts stone clearing, and the result is that the stone clearing effect is actually very Limited, it is difficult to achieve the effect, so it has not been fully promoted and applied clinically
