Abstract
The utility model relates to an endoscope used for diagnosis and treatment of kidney diseases, which belongs to the field of medical instruments. The hardness-adjustable nephroscope comprises a nephroscope body, an operating handle and a nephroscope hardness adjustment supporting rod. The nephroscope body is changed into a hard nephroscope by controlling the supporting rod to move forward in the nephroscope body, the sufficient hardness is ensured to overcome the resistance, and a hard sheath is not required when the hardness-adjustable nephroscope enters in the kidney; during the operation, the nephroscope hardness adjustment supporting rod is moved under the motion of a hardness adjusting key to enable the front end of the nephroscope to become soft from hard, and the required operation is flexibly finished; and the nephroscope overcomes the defect that a blind area exists in the hard type nephroscope, the outer diameter of the nephroscope body is obviously increased, the quality and the space of the working channels are increased, and the operation is more convenient. Compared with the prior art, the utility model can obviously overcome the defects of various nephroscopes, improve the efficiency of a surgery and the economic value and reduce the cost.
Description
Technical field
This utility model belongs to the medical surgical instrument field, is specifically related to a kind of endoscope that is used for the kidney disease diagnosis and treatment.
Background technology
When diagnosis and treatment kidney disease, especially when renal calculus was treated, ureterorenoscope was essential medical surgical instrument on the clinical medicine.Traditional ureterorenoscope apparatus can be divided into two kinds in rigid, soft mirror.Clinical practice shows, rigid ureterorenoscope opereating specification limitation wherein can only be operated one to two renal calices at every turn, and especially the treatment effeciency to complexity renal calculus is very low, and rigid ureterorenoscope easily causes damage to renal tissue, and postoperative complication is more; Soft ureterorenoscope is called the ureter soft lens, and its mirror image is less with the rigid surgical field of view of comparing, and owes clear, does not have enough operation technique channel spaces, can't carry out ultrasonic absorption rubble, laser lithotripsy etc.; And its mirror body is long thinner, and mirror body hardness is not enough, is subjected to and organizes the influence of a frictional force bigger, operates underaction in the art, and positioning and fixing is difficulty, and the operator often need pay the long time and carry out this operating technology of learning and mastering.
Summary of the invention
The purpose of this utility model is to overcome many deficiencies that at present various clinically ureterorenoscopies exist, and a kind of adjustable fibronephorscope of soft or hard that is used for the kidney disease diagnosis and treatment is provided.The adjustable kidney mirror of this soft or hard can reduce the operation easier of diagnosis and treatment operation, improves operation efficient.
Because there are various deficiencies in all kinds of urethrocystoscopes that generally use clinically at present, for overcoming the defective of prior art, this utility model improves existing fiber ureteroscope.
This utility model combines the soft ureterorenoscope and the rigid defeated urine kidney duct mirror two class ureters of existing market or application clinically together, mainly regulates support bar by mirror body, operating grip and sight glass soft durometer and forms.
