Abstract
The utility model belongs to medical appliance field and relates to a ureter endoscope with adjustable hardness. The ureter endoscope consists of an endoscope body, an operating handle and an endoscope hardness adjusting knighthead. By controlling the knighthead to move in the endoscope body through an endoscope hardness adjusting key, the endoscope body is turned to be a hard endoscope and enough hardness is ensured to overcome resistance, so the endoscope is unnecessary to get help from a sheath when entering the ureter. The front segment of the endoscope can be turned from hard to soft by adjusting the movement of the knighthead according to needs, and at the same time, the length of the softened segment of the endoscope is adjusted so as to finish the operation flexibly. The knighthead can move in or be pulled out from a knighthead channel to turn the knighthead channel to be a working channel. Compared with prior art, the ureter endoscope can obviously overcome the disadvantages of various ureter endoscopes, improves operation efficiency and diagnosis and treatment technology level, avoids damages to the tissues and reduces appliance purchase cost.
Description
Technical field
This utility model relates to the medical surgical instrument field, relates to a kind of endoscope that is used for the ureteral diagnosis and treatment.Be specifically related to soft, the hard ureterorenoscope of a kind of scalable.
Background technology
When diagnosis and treatment ureteral, ureteroscope is essential on the clinical medicine.Traditional ureteroscope can be divided into can be divided into two kinds in rigid, soft mirror.Wherein, being most widely used of rigid urethrocystoscope, rigid urethrocystoscope is because the reason of material, and bigger to patient's damage, complication is more.In addition, hard mirror is the optics sight glass, and the sight glass visual angle is generally 0 °, 5 °, and its optical system imaging effect is relatively poor, and the bladder irrigation that need not stop when operation could guarantee surgical field of view clearly.Fiber bladder soft lens is soft mirror, and such scope because mirror body hardness is not enough, need just can enter ureter by the epitheca of relative hard when operation, and operation is restricted.The soft sight glass of this kind also exist lack enough service aisle, the visual field less, since soft mirror body with organize between friction, shortcoming such as its operation easier is big.
Summary of the invention
The purpose of this utility model is to overcome many deficiencies that at present various clinically ureteroscopies exist, and a kind of endoscope that is used for the ureteral diagnosis and treatment is provided, and is specifically related to soft, the hard ureterorenoscope of a kind of scalable.
This utility model combines the soft ureteroscope and the rigid ureteroscope two class ureters of existing market or application clinically together, prepares a kind of adjustable fiber ureteroscope of soft or hard that is used for the ureteral diagnosis and treatment.Can reduce the operation easier of diagnosis and treatment operation, improve operation efficient, reduce manufacturing cost, improve economic worth and clinical efficacy.
This utility model improves the fiber ureteroscope of prior art.
This utility model is mainly regulated support bar by mirror body, operating grip and sight glass hardness and is formed.
Described mirror body (1) length is 50 ~ 150cm, and effective preferred 75-85cm of active length, diameter 5 ~ 18Fr, preferred 7 ~ 12Fr, mirror body can finish upwards 180 ° of downward 180 ° of bendings and 130 ° of second angle is bent downwardly the operation that helps performing the operation; Mirror body front end is inclined design, and the aperture on the inclined-plane is 6 ~ 11Fr, is convenient to enter the operation of ureteric orifice, and can avoid damaged tissue; The mirror body is interior by service aisle, Inlet and outlet water passage, optical-fibre channel, the light source passage, and the sight glass soft or hard is regulated support bar passage composition, and wherein sight glass soft durometer adjusting support bar passage is positioned at the nearly core of mirror body.
