Description
Technical field
This utility model relates to a kind of operating theater instruments, relates in particular to a kind of flexible electronics renal pelvis of head mirror for clinical PCN operation.
Background technology
Along with scientific and technical development, the apparatus in modern surgical operation is also more and more, and operating theater instruments can well help the doctor to complete operation, improves convenience and safety.In urological operation, removing renal calculus needs interventional therapy to solve, and generally uses extracorporeal shock-wave lithotripsy (ESWL), lithotomy in the kidney that drives in the wrong direction, percutaneous nephrolithotomy.Therefore often need to use endoscope in operation, then coordinate apparatus to implement operation.Disclose Chinese patent in existing document: " a kind of PCN (ZL200320122627.1) " it comprise epitheca, with the endoscope of objective system, in described endoscope, the centrage of instrument channel is parallel with the centrage of epitheca, viewing system in endoscope and the mirror body angle that tilts, and the corner below the endoscopic observation system is equipped with a prism, the first eyeglass in objective system has a viewing directional angle, and the magnitude range of viewing directional angle is 6 ° ~ 15 °." a kind of ureterorenoscope (CN2410975Y) ", it comprises outer telescop, outer telescop is fixed in mirror inserts, and mirror is plugged and is provided with light and inserts, and is provided with scope pipe and the operating theater instruments passage of mutual isolation in outer telescop, imaging optical system is located in the scope pipe, the fibre light guide system is located at the part except scope pipe and operating theater instruments passage in outer telescop, and the slotting rear portion of mirror is provided with the mirror body, and the mirror body is connected with lens barrel and lock nut, lock nut is connected with three-way valve, outer telescop from layer section to head by slightly forming to segmenting three joints.But said structure does not possess angle of bend, can't arrive smoothly small cup and inferior calyx, observe and lithotrity effect bad.
Summary of the invention
It is a kind of simple in structure that this utility model provides, and has suitable angle of bend and bending radius, can easily arrive on renal pelvis, kidney the flexible electronics renal pelvis of the head end mirror of small cup and kidney inferior calyx; Solved the electronics renal pelvis mirror inconvenience existed in the prior art and operated in the renal calices of complex structure, the visual field is technical problem not clearly.
This utility model also provides a kind of rubble to get stone simultaneously and has not stayed dead angle, convenient sterilizing, the convenient flexible electronics renal pelvis of the head end mirror that rubble is rinsed; The instrument channel that has solved the renal pelvis mirror existed in the prior art is large not, can not meet rubble and the technical problem of getting the requirement of stone.
Above-mentioned technical problem of the present utility model solves by following technical proposals: the flexible electronics renal pelvis of a kind of head end mirror, comprise operating grip, an end at operating grip is connected with the mirror pipe, be provided with light guide opening on operating grip, be connected with light guide structure by light guide opening, it is characterized in that: described mirror pipe comprises the insertion section connected successively, bending section and first end, described bending section is controlled by the crank handle be positioned on operating grip, bending section is to have snake bone to connect and compose, the pitch that respectively saves snake bone near first end is less than the pitch that respectively saves snake bone near insertion section.The doctor utilizes operating grip to control the angle of bend of the bending section of mirror pipe, and formerly the object lens imaging system is installed in end, by the object lens imaging system, observes the renal pelvis situation.Utilize the light guide opening access light source on operating grip, the object lens imaging system is thrown light on, improve visibility.
PCN puncture general from human kidney small cup enter, in order to allow first end enter smoothly near upper small cup and the inferior calyx of puncture sheath, go to find the calculus target, the bending section of fujinon electronic video endoscope must have superpower crooking ability, and the angle of bend of super large and extra small bending radius namely will be arranged.And the feature with continuous variation bending radius.When the snake bone pitch of front end is less than the snake bone pitch of rear end, make the corner cut of front end be greater than the corner cut of rear end, when snake bone work is crooked, just can reach the front end bending radius little, the effect that the rear end bending radius is large, make first end can arrive smoothly upper small cup and the inferior calyx in renal pelvis, also facilitate and find calculus simultaneously.
As preferably, described operating grip is provided with water inlet and apparatus entrance, and water inlet and apparatus entrance are positioned near mirror pipe one side.Intake calculus is rinsed by water inlet, water inlet has hydraulic valve to control switching.The apparatus entrance can insert holmium laser seal wire and other operating theater instruments, and along instrument channel, insertion section, footpath, bending section and first end until stretch out overseas, are used for carrying out rubble and other operation techniques.
As preferably, described light guide opening is connected with the leaded light intercalation part by light pipe, and the leaded light intercalation part is connected with cable plug by cable, and cable plug is provided with disinfection cap, and described leaded light intercalation part is provided with optical socket.Described leaded light intercalation part is provided with the mouth that leaks hunting.Disinfection cap is for guaranteeing sealing.The mouth that leaks hunting is use when the renal pelvis mirror carries out safety inspection, and inspection method is used the leak detector air that injection pressure is 20 ~ 40Kpa on the mouth that leaks hunting, and after observing its sealing, endoscope could be used.
As preferably, be provided with instrument channel, guide lighting channel and the imaging band be parallel to each other in described mirror pipe.Described instrument channel is greater than guide lighting channel and imaging band.Instrument channel is larger, can be conducive to large flow punching and fill with, and washes away the rubble be crashed to pieces, and keeps the clean of camera lens, can, in instrument channel, by cover stone indigo plant, calculus be taken out, also the convenient turnover of using holmium laser seal wire and other apparatuses simultaneously.
Therefore, the flexible electronics renal pelvis of head end of the present utility model mirror possesses following advantage:
(1), there is suitable angle of bend and bending radius, endoscope's tip can conveniently arrive small cup, kidney inferior calyx on renal pelvis, kidney, rubble is got stone and is not stayed dead angle.
(2), there is the super large instrument channel, can meet high flux flushing and the blue lithotomy of cover stone.
