Mirror gets a clear view；The a large amount of flushing waters of operative process enter renal plevis, and Flexible ureteroscope expansion epitheca operating space is small, and operation is led
The blood clot of cause can not be excreted smoothly, cause Renal pelvic pressure drastically to increase, and cause bacterium, toxin largely to enter in the short time
The circulatory system, produces a large amount of inflammatory factors, causes systemic inflammatory response.How to make to reduce urine output in Flexible ureteroscope lithotrity
Pipe, Renal pelvic pressure, effectively prevent Flexible ureteroscope lithotrity to cause septicopyemia and keep surgical field of view clear, be to secrete at present
Urinate the problem of surgery concern.
The content of the invention
Can not enhancing perfusion physiological saline, and renal plevis it is an object of the invention to solve current Flexible ureteroscope guide sheath
Smooth, blood clot does not discharge ill problem there is provided a kind of Flexible ureteroscope guide sheath for interior pressure release, can realize enhancing perfusion physiology
Salt solution function and vacuum suction function, simplify operation technique, ensure operation safety.
The technical solution adopted for the present invention to solve the technical problems is：A kind of Flexible ureteroscope guide sheath, including protheca
Body and rear sheath, the front portion of preceding sheath is hollow straight tube, the bowl-shaped portion of straight tube rear end connection horn mouth expansion, the bowl of bowl-shaped portion
Bottom center is connected with straight tube, and rear sheath is the housing of front opening, and rear sheath front end is threadedly coupled with the rear end of bowl-shaped portion, rear sheath
The rear end face of body is provided with the soft lens passed through for soft lens and penetrates mouth, and soft lens penetrates mouth and is adapted to soft lens telescope external diameter and less than straight tube
Internal diameter, the water inlet of the side of rear sheath provided with connection irrigating solution, opposite side sets the delivery port of connection negative pressure suction device,
Water inlet and delivery port are respectively arranged with stop valve.Preceding sheath is first inserted in ureter under the auxiliary of seal wire and inner core, then
Inner core is taken out, then rear sheath and the threaded connection of preceding sheath is combined.Sheath and preceding sheath junction coordinate real using screw thread afterwards
Now seal, the soft lens of the rear end of rear sheath penetrates mouth and cooperatively forms closed environment with soft lens telescope, makes in preceding sheath and rear sheath
It is formed at the cavity of straight tube connection.Control physiological saline to pour into cleaning by the stop valve of water inlet, make surgical field of view clear, lead to
Crossing the stop valve of delivery port can control negative pressure suction device to attract, discharge clot and water for cleaning, in reduction ureter, renal plevis
Pressure.It is simple to operate, it is not necessary to change apparatus, it is ensured that operation safety, improve procedure efficiency.Soft lens penetrates mouth and soft lens telescope external diameter
Adaptation forms closing and avoids seepage, and the internal diameter of straight tube is more than soft lens telescope external diameter, circulated for liquid.
Preferably, the rear end of the bowl-shaped portion sets internal thread, rear sheath front end to be correspondingly arranged external screw thread.Avoid screw thread
Tissue and hair are clamped to during combination.
Preferably, the guide sheath is also with inner core is arranged with, inner core front portion is the plug of insertion straight tube, the axis of inner core
Line is provided with the mesopore passed through for seal wire.
Preferably, plug rear end connects I-shaped connecting portion, connecting portion is included in the middle part of two side arms and connection two side arms
Linking arm, the linking arm central integral of plug and connecting portion fixes, and the front end of two side arms is provided with the hook to inner bulge, institute
The outer wall for stating bowl-shaped portion rear end is provided with the annular nib coordinated with hook.
Preferably, when the inner core is assembled with preceding sheath, inner core front end passes the front end of straight tube, and the front end of inner core is cone
Forming head.
Preferably, the soft lens of the rear sheath penetrates intraoral be equipped with for sealed elastic rubber ring.
The present invention sets the cavity connected with straight tube in the rear end of guide sheath, and cavity both sides set turnover aquaporin respectively,
Physiological saline can be poured into and ensure surgical field of view, and energy vacuum suction reduction ureter, Renal pelvic pressure, it is ensured that operation safety.
