Description
Technical field
The present invention relates to a kind of percutaneous nephrolithies with independent bending instrument channel, belong to the field of medical instrument technology.
Background technology
Percutaneous nephrolithy is clinically to handle the conventional means of staghorn stone of kidney and kidney calices or calculus in diverticulum, and patient is first
Through the small of the back skin establish puncture channel under B ultrasound or x-ray guiding, it is then stretched after channel be placed in percutaneous nephrolithy, use
The technologies such as ultrasound, laser carry out rubble, and the patient of the above ponding of moderate, percutaneous nephrolithy operation are merged for solitary pyelolithiasis
Have many advantages, such as that wound is small, the time is short, lithotrity effect is good, but in the calculus for handling parallel small cup calculus or other dead angle positions
When, since the viewing directional angle of traditional hard scape camera end is generally 12 degree, visual range is limited, may cause to find calculus difficulty, and
And instrument channel is integrated with aquaporin, even if calculus is in visual range, due to laser fiber can not bendable, still without
Method, which aims at, carries out rubble, if changing by force into mirror angle or increasing puncture channel, can lead to the damage of renal tissue, and prolong
Long operating time increases the probability of the complication such as channel bleeding.Percutaneous nephrolithy joint Flexible ureteroscope is current processing complexity
The effective means of calculus, but due to the limitation of Flexible ureteroscope bending radius, it is narrow for part lower calyx calculus and small cup neck
Patient, lithotrity effect is still undesirable, and artificially increases operating time and operating difficulty.
Chinese patent document (publication number CN103622661A) discloses a kind of hard percutaneous nephrolithy of bendable front end, preceding
End is designed as the instrument channel of bending, and the kidney lens device in the program is when being performed the operation, because of the shank design of front end bending
Can have bending radius, this will the additional operation difficulty for increasing operation, in percutaneous nephrolithy operation especially uronephrosis unobvious,
When small cup neck is narrow and impracticable, the anatomical structure complexity of kidney aggregation system determines that straight line mirror body is only percutaneous nephrolithy
The optimal selection of operation, but there are still aforementioned many deficiencies for straight line mirror body.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of transdermal nephroscope device, and the hard mirror is by changing camera lens apex
The visual direction angle in portion and the individual instruments channel that front end bending is arranged assist the hard mirror of tradition to carry out laser to complexity calculus broken
Stone improves the lithotrity effect of traditional percutaneous nephrolithy, shortens operating time, reduce the probability of postoperative complications.
Technical scheme is as follows：
A kind of percutaneous nephrolithy with independent bending instrument channel, including hard mirror body and holding part；
Hard mirror body is straight line mirror body, and aquaporin and optics toning system are equipped in hard mirror body, and aquaporin is interior logical equipped with instrument
Road, instrument channel front end are curved end, and optics toning system end is equipped with camera lens, and the radial direction of plane where camera lens and hard mirror body is flat
Face is inclined to set, and hard mirror body one end is connected with holding part；
Holding part includes operating walk way, and operating walk way is connected with hard mirror body one end, and operating walk way one end is equipped with instrument channel
Entrance and the water valve that comes in and goes out.
According to currently preferred, the angle where camera lens between plane and the sagittal plane of hard mirror body is camera lens visual direction
Angle, camera lens viewing directional angle are 15-90 degree.
According to currently preferred, the front end curved end of instrument channel is located inside hard mirror body.Instrument channel without departing from
The formalness of hard mirror body, so the hard mirror body of whole device is still of a straight line type.
It is further preferred that camera lens is located at the front end of instrument channel curved end.Front end is hard mirror body axial advancement direction
Front end, camera lens formerly to observe and to operate, also allows for the instrument channel of engagement flex and different camera lens viewing directional angles；Instrument
The entrance in channel is located at camera lens rear end.
It is further preferred that the bending radius of the curved end of instrument channel is 2.5~3.5mm.
It is further preferred that the Bladder stone fibre diameter used on the market at present is 200 μm~1mm, instrument of the present invention is logical
Road internal diameter is set as 1~1.5mm.
It is further preferred that projected length of the camera lens leading end portion of camera lens on hard mirror body sagittal plane is L, L 2.5mm
~6mm.The inclination in different angles in hard mirror body of camera lens leading end portion, the L of corresponding different length, L namely camera lens change camera lens
Lens length after viewing directional angle angle, the projected length of camera lens leading end portion is also different under different camera lens viewing directional angles.
According to currently preferred, holding part further includes optic delivery channel, and optic delivery channel is connected with operating walk way,
Optic delivery channel is connected by operating walk way with the optics toning system in hard mirror body.Two parts are connected as the aobvious of whole device
Shadow path.
It is further preferred that optic delivery channel rear end is equipped with eyepiece.Affected part situation is observed for operator.
It is further preferred that optic delivery channel is equipped with semicircular finger ring with operating walk way junction.It is carried out as operation
When main manipulator impetus.
The beneficial effects of the present invention are：

, can be in the case where separately not increasing puncture channel when clinically handling complexity calculus such as parallel small cup calculus, auxiliary tradition
Hard mirror carries out calculus to look at lower Ho.YAG laser lithotripsy straight, reduces the damage repeatedly punctured to renal tissue, and improve calculifragous efficiency,
Residual stones are reduced, the lithotrity effect of phase percutaneous nephrolithy operation is improved.
The present apparatus does not extend and is bent mirror body additionally, but is arranged what front end was bent in the tube chamber of traditional line mirror body
The change completion in individual instruments channel, cooperation camera lens visual direction angle can look at lower laser lithotripsy straight.In percutaneous nephrolithy operation especially
It is when uronephrosis unobvious, small cup neck are narrow and impracticable, the anatomical structure complexity of kidney aggregation system determines straight line
Mirror body is only the optimal selection of percutaneous nephrolithy operation, and the present invention is exactly on the basis of ensureing traditional line mirror body, to shank elder generation
The camera lens angle of inclination of end is changed, and the individual instruments channel of front end bending is arranged, so as to difficult to the hard mirror of tradition
With visit and calculus carry out looking at lower laser lithotripsy straight.
The magnitude range of the feature multidimensional viewing directional angle of traditional hard mirror is 6~15 degree, and best visual direction angle is 12 degree.But this hair
Bright be exactly based on increases visual direction angle (15-90 degree), and the individual instruments channel for coordinating front end to be bent, and completes the hard mirror of tradition and is difficult to
The surgical procedure of completion.
