Abstract

The invention relates to an endoscope and lithotripsy all-in-one device for the urinary system. The endoscope and lithotripsy all-in-one device for the urinary system comprises a light source, a light transmitting optical fiber channel, an imaging optical fiber channel, a lithotripsy assembly channel, an image transmitting optical fiber and an image display device. The light transmitting optical fiber channel, the imaging optical fiber channel and the lithotripsy assembly channel are all arranged in sheaths. The sheaths comprise the sheath I and the sheath II which are hinged to each other. Two sliding grooves which are arranged axially are symmetrically formed in the outer wall of the sheath I. An endoscope further comprises a swinging driving device. The swinging driving device is used for controlling the sheath II 4 to swing at the far end. According to the endoscope and lithotripsy all-in-one device for the urinary system, the lithotripsy end of the endoscope and lithotripsy all-in-one device can be bent to different degrees according to needs, the endoscope and lithotripsy all-in-one device is suitable for the diagnosis and treatment of stone in any part of the bladder, no blind area exists in the version in the bladder, the defect of an existing bladder lithotriptoscope is overcome, the application range of the bladder lithotriptoscope is remarkably broadened, the residual rate of the bladder stone is lowered, the pain of a patient is relieved, and the burden of the patient is lightened.

Description

A kind of endoscope's rubble integrated device for urinary system

Technical field

The present invention relates to medical instrument technical field, be specifically related to a kind of endoscope's rubble integrated device for urinary system.

Background technology

Vesical calculus can have kidney, ureteral calculus to be displaced downwardly to due to bladder, also can be by lower urinary tract obstruction, and as urethral stricture, congenital malformation, prostatic hyperplasia etc. cause, vesical calculus section causes myxocystitis to sexually revise for a long time, the canceration of even boring a hole.As lower urinary tract obstruction or calculus cause bladder neck to block, intravesical can form girder, cell, and calculus in secondary diverticulum of bladder is difficult to treatment more.Current cystolithic primary treatment method has: extracorporeal shock-wave lithotomy (ESWL), intracavity cystoscope rubble lithotomy and cystolithectomy, but because extracorporeal shock-wave lithotomy is subject to the impact of the factor such as pelvis structure, calculus mobility, poor effect.And cystolithectomy, because wound is eliminated more gradually, along with the development of intracavity technology, has become cystolithic first-selected Therapeutic Method through cystoscope rubble.The cystoscope rubble lithotomy that used now, because cystoscope is straightforward hard mirror, inflexibility, the calculus that the interior calculus of diverticulum of bladder or close bladder front side wall and near the portion of internal urethral orifice bit position are fixed, cystoscope or calculi breaking device are difficult to arrive, significant limitation the scope of application of bladder lithotriptoscepe, often need to change open surgery, increase patient's misery and burden.

The present invention is the deficiency solving the problems of the technologies described above, the technical scheme adopting is: a kind of endoscope's rubble integrated device for urinary system, comprise light source, optical coupling part, lose optical-fibre channel, imaging fibre passage, rubble assembly passage, defeated picture optical fiber, image coupling unit and image display device, described losing in optical-fibre channel and imaging fibre passage is respectively equipped with and loses optical fiber and imaging fibre, light source is connected and is lost optical fiber by optical coupling part, imaging fibre is connected with image coupling unit, image coupling unit connects image display device by defeated picture optical fiber, in rubble assembly passage, be provided with holmium laser fiber, the described optical-fibre channel of losing, imaging fibre passage and rubble assembly passage are all arranged in sheath pipe, described sheath pipe is made up of sheath pipe I and sheath pipe II, sheath pipe I and sheath pipe II are hinged by bearing pin, on the outer wall of sheath pipe I, be arranged with two chutes that arrange vertically, described endoscope also comprises oscillatory gearing mechanism, driving device is mainly by two gears, a driven wheel, two tooth bars and two pull-push piece compositions, two tooth bars are fastened on respectively in chute, and all can produce axial displacement along chute, two gears are all arranged on sheath pipe I one end away from sheath pipe II, and be meshed respectively at two tooth bars, described two gears are all connected with coaxial driven gear, driven wheel is arranged between two driven gears and with two driven gears and all engages, two tooth bars are connected with sheath pipe II by pull-push piece respectively away from gear one end, described pull-push piece is plastic material.

Described sheath pipe I is in the enclosure sheathed.

Described driven wheel is connected with thumb wheel.

beneficial effect

Endoscope of the present invention rubble integrated device, its rubble end can carry out bending in various degree as required, applicable to calculus diagnosis and the treatment at any position of intravesical, non-blind area is accomplished in the intravesical visual field, make up the deficiency of existing bladder lithotriptoscepe, the scope of application that has obviously improved bladder lithotriptoscepe, reduces cystolithic residual rate, reduces patient's painful and burden.
