Abstract
The utility model is related to a kind of bending conduit sheaths, belong to medical instruments field, the bending conduit sheath, the sheath tube socket that is connected including sheath, with the sheath, with the sheath tube socket connecting tube connected and the threeway connected with the connecting tube, the rear end of the sheath tube socket is provided with the sealing valve of detachable threaded connection, the sheath is in bending, and in the middle, the angle in knee is 100 degree~110 degree and in smooth curved in the knee of the sheath.In the medical operating of the organs such as treatment bladder, especially when replacing double J pipe, the utility model product has better support force and internal patency, and healthcare givers also has the visual field of bigger to observe lesion, treatment lesion internal organs more comprehensively, safe.
Description
Technical field
The utility model belongs to medical instruments field more particularly to a kind of bending conduit sheath for being used to aid in interventional treatment.
Background technology
The illness of human urethra and bladder is more, is checked, is performed the operation using urethrocystoscope, because it is directly perceived, correct, and
The multiple advantages such as dynamically recording can be permanently left, institute is widely used by clinical treatment.Catheter sheath is that urethrocystoscope is examined in clinic
Look into the important composition component in surgical procedure, urinary catheter expansion can be carried out, and continue keep passage, for injection and pumping liquid with
And the related equipments such as endoscope are inserted and removed from.
Clinically common catheter sheath forms for pedestal and sheath two parts, and base side has a connecting tube and threeway, can
Blood sample, pressure monitoring, injection of medicine or contrast agent etc. are extracted in art, there is valve in base portion, and sheath is in open circles tubulose.
In existing clinical technology, establish operation path be typically per urethra be expanded into or direct transdermal puncture, and by endoscope, swash
The medical instruments such as light optical fiber are introduced directly into one by one in bladder or the urinary tract.
For existing catheter sheath when treating bladder class disease, the sheath of conventional catheters sheath is straight hollow circular-tube, is being inserted into
It is unstable to catheter sheath can be caused to fix during bladder, it is narrow and small in the intravesical visual field when being put into endoscope by catheter sheath, it is impossible to
Comprehensive observation diseased region.
The content of the invention
To overcome above-mentioned technical problem, the utility model provides a kind of simple in structure, safe and reliable, easy to use curved
Bent catheter sheath.
To achieve the above object, the utility model is realized using following technical scheme：A kind of bending conduit sheath, including
Sheath, the sheath tube socket connected with sheath, the connecting tube connected with sheath tube socket and the threeway connected with connecting tube, the sheath tube socket
Rear end is provided with the sealing valve of detachable threaded connection, and the sheath is in bending.
The knee of the sheath is in the middle.
The angle in the knee of the sheath is 100 degree~110 degree and in smooth curved.
The utility model has the positive effect that：
In the medical operating of the organs such as treatment bladder, especially when replacing double J pipe, the utility model product has preferably
Support force and internal patency, healthcare givers also have the visual field of bigger to observe lesion, and treatment lesion more comprehensively, safe is dirty
Device.
Description of the drawings
Fig. 1 is the structure diagram of the catheter sheath of the utility model.
Fig. 2 is the structure diagram of the sealing valve of the utility model.
1st, sheath, 2, pedestal, 3, connecting tube, 4, threeway, 5, sealing valve.
Specific embodiment
Referring to Fig. 1,2, a kind of bending conduit sheath, the sheath tube socket 2 connected including sheath 1, with sheath 1 is connected with sheath tube socket 2
Connecting tube 3 and the threeway 4 that is connected with connecting tube 3, the rear end of sheath tube socket 2 is provided with the sealing valve 5 of detachable threaded connection, sheath
In the middle, the angle in knee is 100 degree~110 degree and in smooth curved in the knee of pipe 1.
The operation principle of the utility model is as follows：
After medical staff removes sealing valve 5, bending conduit sheath is held by pipe tube body is expanded and is inserted into sheath through 2 rear end of sheath tube socket
1, dilating urethra is carried out by expanding pipe, after the completion of expansion, expansion pipe is extracted out from sheath base rear end, screwing hermetic valve 5, then
The passage formed through bending conduit sheath is imported or is exported Medical Devices or drug etc..
