Abstract
The utility model relates to a minimally invasive percutaneous nephroscope. In a percutaneous nephrolithotomy operation in which a high-power holmium laser lithotriptic probe rod is applied, the minimally invasive percutaneous nephroscope is matched with a percutaneous nephrolithotomy attraction lithotriptic sheath to be used. A nephroscope body consists of an inserted part, a main body part and an eye lens part, wherein an optical system channel and an appliance channel are arranged in the inserted part; the diameter of the optical system channel is larger than that of the appliance channel; an optical system adopts optical glass to carry out imaging; an optical axis at the front end of the optical system is deflected towards the appliance channel by 5 to 12 degrees; and a front protective sheet is inclined towards the opposite direction of the appliance channel. The minimally invasive percutaneous nephroscope meets the requirements of the percutaneous nephrolithotomy operation; the imaging quality is improved, so as to solve the problem of unclear imaging or low resolution ratio caused by application of an imaging beam due to the larger appliance channel, and the small optical system channel of the existing nephroscope.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of PCN that is applicable to little fistulation percutaneous kidney operation.
Background technology
The PCN of various ways is for guaranteeing its versatility at present, do instrument channel bigger during design, at least can pass through the 6Fr apparatus, the outer telescop size can not be excessive situation under, the optical system passage of this PCN will be very thin, increased the difficulty of optics processing, reduce the eyeglass precision, and in optical system, added to pass and resemble bundle, limited the resolution of optical system, make the angle of visual field of endoscope little and imaging is unintelligible, make troubles to operation technique.
Summary of the invention
The purpose of this utility model is to provide that a kind of imaging is clear, the angle of visual field is big, and can be applied in little fistulation percutaneous kidney operation of high-power holmium laser lithotripsy the micro-wound percutaneous kidney mirror that cooperates little fistulation to attract the clear stone sheath of rubble to use.
Technical solution of the present invention:
Micro-wound percutaneous kidney mirror comprises insertion portion, main part, eyepiece part, and insertion portion inside is provided with optical system passage and instrument channel.The optical system channel diameter is greater than the instrument channel diameter; optical system adopts the optical glass imaging; the optical system front end makes optical axis direction instrument channel deviation 5-12 degree; guarantee that holmium laser feeler lever can appear in the sight glass visual field when stretching out mirror body 10-25mm; and preceding screening glass tilts to the rightabout of instrument channel, avoids the damage of holmium laser feeler lever to eyeglass.Be provided with a notched ring-type finger ring in eyepiece part upper end.
This utility model adopts said structure, has reduced difficulty of processing, improves image quality, has obtained the big angle of visual field, high-resolution PCN, has satisfied with little fistulation to attract the clear stone sheath of rubble to cooperate the needs of clinical operation.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
Micro-wound percutaneous kidney mirror comprises insertion portion 1, main part 2, eyepiece part 3, in insertion portion 1, be provided with optical system passage 4 and instrument channel 5, the optical system channel diameter in the present embodiment extremely can be by the operating theater instruments of 4Fr with instrument channel 5 reduced greater than the diameter of instrument channel; Use the optical glass imaging in the optical system, improved image quality greatly; System optical axis guarantee that holmium laser feeler lever 7 can appear in the sight glass visual field when stretching out 15mm, and preceding screening glass 8 avoids holmium laser feeler lever that eyeglass is had damage to instrument channel 5 inclination in the other direction to instrument channel deviation 5 degree.Eyepiece part top is provided with a band breach ring-type finger ring, is easy to control, and is more conducive to operator's operation.
Claims (2)
1. micro-wound percutaneous kidney mirror; comprise insertion portion, main part, eyepiece part; insertion portion inside is provided with optical system passage and instrument channel; it is characterized in that described optical system adopts the optical glass imaging; the optical system channel diameter is greater than the instrument channel diameter; optical system front end optical axis direction instrument channel deviation 5-12 degree, preceding screening glass tilts to the rightabout of instrument channel.
