Abstract
The utility model discloses a guide sheath for a ureter. The guide sheath for the ureter comprises a guide sheath body, a tray and an expansion pipe, wherein the rear end of the guide sheath body is sleeved with the front end of the tray, the expansion pipe is inserted into the tray and the guide sheath body in sequence, the front end of the expansion pipe extends out of the front end of the guide sheath body, the rear end of the expansion pipe extends out of the rear end of the tray, the rear end of the expansion pipe is connected with an expansion pipe connector with a cavity, and a drainage port is laterally formed in the tray. According to the guide sheath for the ureter, liquid which flows out through the guide sheath body in the process of an operation can be rapidly drained and discharged, the liquid is prevented from contaminating an operative region and instruments and equipment, and safety and convenience of the operation are improved.
Description
Technical field
This utility model relates to a kind of medical appliance, relates in particular to a kind of ureter guiding sheath.
Background technology
Ureter guiding sheath is the core apparatus for the urology procedure through endoscope, can carry out dilatation of ureter, and continues to keep ureter passage, supplies the insertion of the related equipments such as injection and pumping liquid and endoscope and shifts out.Guiding sheath external member is comprised of flexible sheath body and dilating catheter, and apparatus after getting involved takes out dilating catheter, and sheath body is placed in temporarily in body and forms pipeline for subsequent procedures.In use procedure, sheath body is got involved after ureter through urethra, bladder, other liquid that produce in the former urine flowing out through ureter and operation process just can flow out by the cavity of sheath, existing product does not arrange effective liquid drain and retracting device at near-end pallet, therefore operating theater instruments and environment are easily subject to the pollution of effluent, impact operation efficiency, has lowered the safety of performing the operation.
Utility model content
The purpose of this utility model is to provide a kind of ureter guiding sheath, can carry out drain collection to the liquid being flowed out by guiding sheath sheath body in operation process, avoids its contaminated operation apparatus and surgical environments, improves operation technique efficiency and operation safety.
For achieving the above object, this utility model provides a kind of ureter guiding sheath, comprise guiding sheath sheath body, pallet and convergent divergent channel, the front end sleeve of described pallet is in the rear end of described guiding sheath sheath body, described convergent divergent channel inserts in described pallet and described guiding sheath sheath body successively, and, the front end of described convergent divergent channel stretches out the front end of described guiding sheath sheath body, the rear end of described pallet is stretched out in the rear end of described convergent divergent channel, the rear end of described convergent divergent channel is connected with the convergent divergent channel joint with cavity, and described pallet side direction is provided with draining hole.
Preferably, described pallet side direction is provided with the drainage tube joint with described draining hole fluid communication.
Preferably, the cavity bearing of trend of the cavity bearing of trend of described drainage tube joint and described guiding sheath sheath body is an angle and this angle is less than or equal to 90 °.
Preferably, described angle is 30 °, 45 °, 60 ° or 90 °.
Preferably, described guiding sheath sheath body is spring interlayer reinforced pipe.
Preferably, on the inner and outer wall of described guiding sheath sheath body, be all coated with lubricated biological coating.
Compared with prior art, ureter guiding sheath of the present utility model is by being provided with draining hole in pallet side direction, can and drain pallet position and collect the liquid collecting flowing out through guiding sheath sheath body, avoid its contaminated operation apparatus and surgical environments, keep the clean and tidy of pallet and get a clear view, be convenient to character and quantity that doctor observes trickle simultaneously, contribute to medical personnel to judge the process of operation, improve operation efficiency and operation safety.
By following description also by reference to the accompanying drawings, it is more clear that this utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model ureter guiding sheath embodiment mono-.
Fig. 2 is the partial schematic diagram of this utility model ureter guiding sheath embodiment bis-.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 1-2, described ureter guiding sheath comprises guiding sheath sheath body 1, pallet 2 and convergent divergent channel 3.The front end sleeve of described pallet 2 is in the rear end of described guiding sheath sheath body 1, described convergent divergent channel 3 inserts in described pallet 2 and described guiding sheath sheath body 1 successively, and the front end of described convergent divergent channel 3 stretches out the front end of described guiding sheath sheath body 1, the rear end of described pallet 2 is stretched out in the rear end of described convergent divergent channel 3.Described guiding sheath sheath body 1 is spring interlayer reinforced pipe.On the inner and outer wall of described guiding sheath sheath body 1, be all coated with lubricated biological coating, to facilitate guiding sheath sheath body 1 to get involved ureter through urethra, bladder smoothly.Described pallet 2 side direction are provided with draining hole 21.Described pallet 2 side direction are provided with the drainage tube joint 22 with described draining hole 21 fluid communication, and described drainage tube joint 22 extends to form from described draining hole 21.The cavity bearing of trend of the cavity bearing of trend of described drainage tube joint 22 and described guiding sheath sheath body 1 is an angle a, and this angle a is less than or equal to 90 °, in specific embodiment, this angle a can (in embodiment illustrated in fig. 1 one, this angle a be 45 degree for 30 °, 45 °, 60 ° or 90 °, in embodiment illustrated in fig. 2 two, this angle a is 90 degree), the liquid drain that this angle a is convenient in pallet 2 is easy to the plug-pull tube operation of drainage tube joint 22 simultaneously, and can not affect the operation of medical personnel to operating theater instruments such as guiding sheath sheath body 1 and endoscopies in enough operation processs.The front end of described convergent divergent channel 3 is cone point, and the rear end of described convergent divergent channel 3 is connected with the convergent divergent channel joint 4 with cavity.
Above combination most preferred embodiment is described this utility model, but this utility model is not limited to the embodiment of above announcement, and should contain the various modifications of carrying out according to essence of the present utility model, equivalent combinations.
