Abstract

The invention relates to the field of medical instruments, and particularly discloses a rigid percutaneous nephroscope with the rigid front end capable of being controlled to be flexural. The rigid percutaneous nephroscope with the flectional front end comprises an endoscope end portion, an endoscope body, a light source input end, an instrument channel, a water inlet channel, a water outlet channel and an image data output end, wherein 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 endoscope body and are communicated with the endoscope end portion. The endoscope end portion comprises a rigid rear end portion arranged at the rear end and the flectional endoscope front end portion arranged at the front end. The endoscope front end portion is controlled by a doctor to be flexural correspondingly and enter a target bile duct, surgical operations which cannot be completed through an ordinary rigid percutaneous nephroscope are completed, surgical modes are increased, the defects of the exiting diagnosis and treatment technology are overcome, and a new tool is provided for curing the percutaneous nephropathy.

Description

A kind of hard PCN of bendable front end

Technical field

The invention belongs to field of medical appliances, be 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

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

Summary of the invention

The object of the invention 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, make up the deficiency of current therapeutic endoscopy renal calculus, increase the modus operandi for the treatment of percutaneous nephropathy, for curing calculus disease, provide new instrument.

In order to reach above-mentioned technical purpose, the present invention is achieved by the following technical programs:

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

In the present invention, the first end of described scope can make progress, downwards, left, four direction is done the bending of angle of bend to the right.

In the present invention, be provided with the first end of control scope and carry out crooked control module in described scope main body, described control module is provided with the locking switch that the angle of bend of the first end of scope 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 the first end of described hard rearward end and scope is all less than or equal to 8mm.

In the present invention, described intake tunnel and exhalant canal lay respectively at the left and right of instrument channel, and are provided with valve, and 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 the first end of scope.

Compared with prior art, the invention has the beneficial effects as follows:

The present invention is designed to flexible version by the first end of hard end, can do suitable bending and turn into and in complicated kidney duct, detect and treat incarceration calculus or polyp therein by controlling the first end of scope, remove patient painful, make up the deficiency of current diagnosis and treatment method.

Accompanying drawing explanation

Fig. 1 is the structural representation of bendable front end hard PCN of the present invention.

Fig. 2 a～Fig. 2 e is the first end bent schematic diagram of scope of the hard PCN of bendable front end of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is described in further detail:

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 on comprising scope end 1, scope main body 2 control modules 8, light source input 3 and being placed in scope main body 2, are connected with scope end 1

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

The bending that angle of bend is less than 60 ° is done in the first end 11 of described flexible scope up and down left and right four direction.

In described scope main body 2, be also provided with control module 8, control module 8 can be controlled the first end 11 of flexible scope upwards, downwards,, etc. four direction carries out bending left to the right, in addition, in described control module 8, go back and be designed with locked switch, the angle of bend of the first end 11 of scope can be fixed.

In the present invention, described intake tunnel 5 and exhalant canal 7 lay respectively at the left and right of instrument channel, and are provided with valve,, the internal diameter of instrument channel 6 is less than or equal to 3.0mm.The optical system of the first end 11 of described scope adopts electronics ccd form, is beneficial to the bending of the first end 11 of scope.

Fig. 2 a～2e is the differently curved angle schematic diagram in the first end 11 of scope described in the present invention.

Wherein: Fig. 2 c is under 11 normal conditions of the first end of scope, now whole scope end 1 is in line, and locked by control module 8;

Fig. 2 a is that the first end 11 of scope is upwards crooked at an angle, and its angle of bend is less than 60 °;

Fig. 2 b is that the first end 11 of scope is crooked at an angle downwards, and angle is less than 60 °;

Fig. 2 d is that the first end 11 of scope is crooked at an angle left, and angle is less than 60 °;

Fig. 2 e is the bending at an angle to the right of the first end 11 of scope, and angle is less than 60 °.Each angle of bend is controlled by control module 8 above, reaches after bend angle, by locking switch, fixes.
