Abstract

The utility model belongs to the field of medical instruments and particularly discloses a hard percutaneous nephroscope set with a curved front end. The hard percutaneous nephroscope set with the curved front end comprises an endorscope end portion, an endorscope main body, a light source input end, an instrument channel, a water inlet channel, a water outlet channel and an image data output end, and the light source input end, the instrument channel, the water inlet channel, the water outlet channel and the image data output end are arranged on the endorscope main body and communicated with the endorscope end portion. The endorscope end portion is composed of a hard rear end portion and a curved endorscope front end portion, the hard rear end portion is arranged at the rear end, the endorscope front end portion is arranged at the front end. A doctor enters into a targeted bile duct by controlling the endorscope front end portion and conducting corresponding curving and completes surgery operation which is not completed by a common hard percutaneous nephroscope set, so that the hard percutaneous nephroscope set with the curved front end increases a surgery form, makes up the defect of existing diagnosis and treatment, and provides a novel tool for curing a percutaneous kidney disease.

Description

A kind of hard PCN of bendable front end

Technical field

This utility model belongs to field of medical appliances, is specifically related to a kind of Novel medical instrument that modern medicine is carried out the operation of percutaneous kidney, i.e. a kind of hard PCN of bendable front end.

Prior art

The PCN operation is the means that solve the renal calculus problem, the skin that the hard PCN is set up by waist enters in the kidney to the passage of kidney, utilizes laser, the rock breaking tool such as ultrasonic, and renal calculus is smashed taking-up, because wound is little, so the damage that causes to human body is also very little.But because the pipeline in the kidney is intricate, if use the comparatively hard PCN in end to perform the operation, for the calculus of some incarcerations in special kidney duct, scope can't turn into smoothly, thereby has missed the killer opportunity of radical cure renal calculus.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of hard PCN of bendable front end is provided, this hard PCN utilizes speciality that front end can the be crooked calculus in kidney enters the special kidney duct of the complicated position treatment incarceration such as kidney duct, remedy the deficiency of present therapeutic endoscopy renal calculus, increase the modus operandi for the treatment of percutaneous nephropathy, provide new instrument for curing the calculus disease.

In order to reach above-mentioned technical purpose, this utility model is achieved by the following technical programs:

The hard PCN of a kind of bendable front end described in the utility model, comprise scope end, scope main body, place on the scope main body and the light source input that is communicated with the scope end, instrument channel, intake tunnel, exhalant canal, view data outfan, described scope end comprises the first end of the hard rearward end that places the rear end and the flexible scope that places front end, and the angle of bend scope of the first end of described scope is less than or equal to 60 °.

In this utility model, described scope elder generation end can make progress, downwards, left, four direction is done the bending of angle of bend to the right.

In this utility model, be provided with control scope elder generation end on the described scope main body and carry out crooked control module, described control module is provided with the locking switch that the angle of bend of scope elder generation end can be fixed and locked.

Described hard rearward end length range is 200～350mm, and the first tip lengths scope of flexible scope is 20～50mm, and the external diameter of described hard rearward end and scope elder generation end is all less than or equal to 8mm.

In this utility model, described intake tunnel and exhalant canal lay respectively at instrument channel about, and be provided with valve, the internal diameter of instrument channel is less than or equal to 3.0mm.

And the optical system of the first end of flexible scope adopts electronics ccd form, is beneficial to the bending of scope elder generation end.

Compared with prior art, the beneficial effects of the utility model are:

This utility model is designed to flexible version with the first end of hard end, can do suitable bending by control scope elder generation end turns in the complicated kidney duct and detects and treat incarceration calculus or polyp therein, remove patient painful, remedy the deficiency of present diagnosis and treatment method.

Fig. 2 a～Fig. 2 e is the scope elder generation crooked schematic diagram in end of the hard PCN of this utility model bendable front end.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in further detail:

Fig. 1 is the structural representation of bendable front end hard PCN described in the utility model.

Described bendable front end hard PCN, the instrument channel 6, intake tunnel 5, exhalant canal 7, view data outfan 4, the control module 8. that are connected with scope end 1 on comprising scope end 1, scope main body 2 control modules 8, light source input 3 and placing scope main body 2

Described scope end 1 comprises the hard rearward end 12 that places the rear end and places the first end 11 of flexible scope of front end, hard rearward end 12 length ranges are 200～250mm, flexible scope elder generation end 11 length ranges are 20～～50mm, the external diameter of described hard rearward end 12 and scope elder generation end 11 is less than or equal to 8mm.

Angle of bend is done less than 60 ° bending in described flexible scope elder generation end 11 up and down left and right sides four direction.

Also be provided with control module 8 on the described scope main body 2, control module 8 can be controlled the first end 11 of flexible scope and make progress, waits four direction to carry out bending downwards, left, to the right, in addition, go back and be designed with locked switch on the described control module 8, the angle of bend of scope elder generation end 11 can be fixed.
