Abstract
The utility model relates to medical equipment, in particular to an ureteroscope outer sheath with an operation duct, which comprises a tubular sheath body (1), wherein an ureteroscope channel (11) and a manipulator channel (12) are arranged in parallel in the sheath body (1) along a tube body direction of the sheath body (1), and the rear end of the sheath body (1) is provided with an arc line-shaped manipulator guide tube (13) with the front end communicated with the manipulator channel (12) along a tangential direction. By using the ureteroscope outer sheath, operating steps of resection of urethral stricture are simplified, a manipulator duct can be used as a backwater pathway, and the washing effect is better, so as to enable visual field to be clearer and an operating position to be more accurate, and avoid the occurrence of a false passage phenomenon. A plasma columnar electrode is used for cutting, so as to enable thermal damage to be smaller, be more beneficial to postoperative healing, and reduce the pain of patients. The ureteroscope outer sheath is simple in structure, and convenient in operation and use.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of ureteroscope epitheca.
Background technology
Urethral stricture is that Urology Surgery deals with one of more thorny disease, and ureteroscope is through being usually used in the treatment of urethral stricture in recent years.The method that adopts at present is at first ureteroscope to be inserted patient's urethra, through the operation duct of ureteroscope seal wire is inserted the urethral stricture position again.Owing to have only an operation duct on the ureteroscope; Just can't import the holmium laser cutter that uses at present when inserting seal wire through ureteroscope; Can only earlier ureteroscope be extracted, seal wire is stayed in patient's urethra, ureteroscope is inserted once more patient's urethra from the next door of seal wire again; The holmium laser cutter inserts patient's urethra from the operation duct of ureteroscope again, carries out the urethral stricture cutting operation.The operating procedure of this urethral stricture cutting operation is complicated, is unfavorable for undergoing surgery rapidly and accurately, can bring bigger misery to the patient simultaneously, and the cutting hot injury of holmium laser cutter is bigger, is unfavorable for the healing of patient's postoperative.The hot injury is less, the plasma electric cutting system of good operation effect though have at present, because the length of plasma column electrode is shorter, can not be used with ureteroscope.In addition, wash when having only an operation duct also to be unfavorable for performing the operation on the ureteroscope, the operation duct on the ureteroscope can only be as intake tunnel, and water outlet can only be flowed out through the other slit of seal wire, and flushing speed is slow, and effect is relatively poor, can cause the visual field unclear.
Summary of the invention
The purpose of this utility model provide a kind of operating procedure simple, can utilize plasma cutters carry out developing result in urethral stricture cutting operation, the operation good, get a clear view have a ureteroscope epitheca of operating the duct.
The technical solution of this utility model is: it comprises the tubular sheath body; Is provided with ureteroscope passage and operator passage side by side along sheath body pipe shaft direction in the sheath body, the rear end of sheath body is provided with the camber line shape operator guiding tube that front end and operator passage tangentially are connected.
The technique effect of this utility model is: use it to simplify the operating procedure of urethral stricture operation, its operator duct can be used as the backwater path, and developing result is better, makes the visual field more clear, makes operating position more accurate, avoids occurring via phenomenon.The hot injury who uses plasma column electrode to cut is littler, more helps the postoperative healing, reduces patient's misery.It is simple in structure, and is easy for operation.
Description of drawings
Accompanying drawing is this utility model embodiment axonometric chart.
The specific embodiment
Shown in accompanying drawing, it comprises tubular sheath body 1, is provided with ureteroscope passage 11 and operator passage 12 side by side along sheath body 1 pipe shaft direction in the sheath body 1, and the rear end of sheath body 1 is provided with the camber line shape operator guiding tube 13 that front end and operator passage 12 tangentially are connected.
Sheath body 1 is made up of with operator channel 16 trocar sheath 14 and the ureteroscope channel 15 that lays respectively in the trocar sheath 14.The rearward end of the external sleeve pipe 14 of sheath is provided with the bluff piece 17 that is vertically fixed on the trocar sheath 14.Rear portion, its front end that operator guiding tube 13 is positioned at bluff piece 17 are connected with the rear end of operator channel 16.The front end of trocar sheath 14, ureteroscope channel 15 and operator channel 16 is respectively inclination shape, and the arris portion of the inclination shape front end of trocar sheath 14 is provided with antisitic defect fillet 18.Ureteroscope channel 15 is an oval pipe, and operator channel 16 is a round tube, and the minor axis of ureteroscope channel 15 is greater than the diameter of operator channel 16.The inwall of ureteroscope channel 15 can be slidingly matched with the outer wall of ureteroscope.The front end of operator guiding tube 13 is provided with tubaeform importing 19.
The utlity model has following advantage:
1, it is thinner than the resectoscope bore, proceeds to narrow location more easily;
2, it can import plasma column electrode when importing seal wire, and operating procedure is simpler, under the observation of ureteroscope, cuts, and cutting position is accurate, can not cause via phenomenon;
3, its operation duct can be used as the backwater path, makes the visual field more clear, is convenient to operation technique more.
