Abstract
The utility model provides a special medical device for curing urethra disruption after pelvis fracturing, which comprises an aerocyst catheter and an outer thimble. The utility model has the advantages of easy manufacture, low cost and convenience in operation. The utility model uses the bushing type aerocyst catheter to cure the urethra disruption after pelvis fracturing, and the utility model has the functions of urethra realignment, traction, internal and external drainage and continuous urethral expansion, which solves the involution reduction of the urethra fractured end, and the utility model has the advantages of less surgery trauma as well as the short time of traction, which also can drain and irrigate the oozing blood, exudates and urethral secretion between the urethra fractured ends, reduce the forming of the hematoma, fibrosis and scar, accelerate the renovation of the urethra wound surface, reduce the incidence of infection and urethra stenosis, so thus reducing or avoiding the urethra renovation surgery in phase II.
Description
Technical field
This utility model relates to a kind of special equipment that is applied to treat posterior urethral rupture, be meant a kind of early time treatment that is applied to the fracture of pelvis posterior urethral rupture especially, integrate the bushing type Foley catheter of urethral realignment, traction, interior external drainage and lasting urethral dilatation.
Background technology
Medical circle is too controversial to the early time treatment method of fracture of pelvis posterior urethral rupture.Traditional Therapeutic Method has: I phase urethra is repaired anastomosis, though this method can reach good anatomical reduction, and the hemorrhage and oozing of blood of may command, cicatrization is few.When the membranous urethra dislocation is especially arranged, adopt this method can avoid the wound posterior urethral stricture.But fracture of pelvis calculi position difficulty, operating field is dark, and operation easier is big, causes the seriously injured wounded to be difficult to bear; Early stage suprapubic cystotomy, the II phase is repaired urethra, though simple, narrow incidence rate height, and need to do the urethra reconstruction after three to six months again, bring misery to the patient; Chinese scholars is advocated early stage suprapubic puncture fistulation more in recent years, internal urethrotomy under the row sight glass of delaying, though short term effect is satisfied, long-term effect is not good enough, and it is many to send out narrow again; Though simple urethral reunion operation is simple, narrow incidence rate is very high, and postoperative needs row urethral dilatation regularly; Urethral realignment adds the method for traction, though use the traction of Foley catheter can make the urethra broken ends of fractured bone obtain to reset effectively, improved therapeutic effect, but because of it can not drain and the flushing urethral secretions, cause urinary tract infection easily, and if traction overweight then may oppress neck of bladder and (or) the bulb urethra causes its ischemic necrosis, even forms urethral fistula, complication is more.
Summary of the invention
The purpose of this utility model just is to overcome the defective of background technology, provides a kind of making easy, easy and simple to handle, integrates the bushing type Foley catheter of urethral realignment, traction, interior external drainage and lasting urethral dilatation.
The purpose of this utility model is realized by following scheme:
Foley catheter of the present utility model is made up of with two-chamber or three-cavity catheter air bag, air bag valve, and trocar sheath is arranged on the catheter.There is a side opening lower end of trocar sheath and two-chamber or three-cavity catheter bifurcated corresponding section, catheter are inserted in trocar sheath from this side opening, and the top that makes the air bag of catheter stretch out trocar sheath, leave the gap of about 2mm between the internal diameter of trocar sheath and the catheter.
Outer sleeve upper of the present utility model has conduction hole.
Inside sloping, trocar sheath of the present utility model top.
This utility model is compared with background technology, has following advantage and effect:
It is easy, with low cost, easy and simple to handle to make, and is easy to grasp.Use this utility model treatment fracture of pelvis posterior urethral rupture, not only operation wound is less, and solved catheter in the past can not drain and the flushing urethral secretions due to the difficult problem of urinary tract infection.The compatibility of silica gel outer tubing and good springiness, both can play support, dilating effect, can play drainage again, integrate urethral realignment, traction, interior external drainage and lasting urethral dilatation, having solved the involutory of the urethra broken ends of fractured bone preferably resets, shortened the pull-in time, but and drain and flush out oozing of blood, sepage and urethral secretions between the urethra broken ends of fractured bone, reduced the formation of organization of hematoma and fibrosis and cicatrix, promote the urethra wound repair, reduce to infect and the incidence rate of urethral stricture, thereby reduce or avoided the prosthesis of II phase urethra.Through clinical practice treatment fracture of pelvis posterior urethral rupture 41 examples, the voluntary micturition rate reaches 94.8% behind the tube drawing, and the irregular urethral dilatation of postoperative average time is 12 months, compares with urethral reunion operation only, the voluntary micturition rate improves 49%, and the postoperative urethral dilatation time then shortens 6 months.Therefore, this utility model has good popularization and application prospect as a kind of special-purpose medical apparatus and instruments for the treatment of the fracture of pelvis posterior urethral rupture.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Shown in the figure: 1 is that air bag, 2 is that conduction hole, 3 is that double channel foley balloon indwelling catheter, 4 is that air bag valve, 5 is that trocar sheath side opening, 6 is trocar sheath.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, and this utility model is not limited to following examples.
With reference to accompanying drawing, this utility model is made of 14F double channel foley balloon indwelling catheter (3) and 22F silica gel outer pipe (6), and double channel foley balloon indwelling catheter (3) is made up of air bag (1), catheter (3) and air bag valve (4).There is a side opening (5) the two-chamber bifurcated corresponding section of the lower end of 22F silica gel outer pipe (6) and catheter (3), catheter (3) is inserted the trocar sheath (6) from side opening (5), and the air bag (1) that makes catheter (3) stretches out the top of trocar sheath (6), leaves the wide gap of 2mm between the internal diameter of trocar sheath (6) and the catheter (3).Inwardly draw the top of trocar sheath (6) in sloping, so that catheter is introduced bladder.There are several conduction holes (2) upper end of trocar sheath (6), and drain in time and periodic flushing go out oozing of blood, sepage and urethral secretions between the urethra broken ends of fractured bone.The urethral realignment traction adds the bushing type drainage, the operation method of its urethral realignment is identical with simple urethral reunion operation, no longer narrate at this, after joining forces 1 catheter is drawn external orifice of urethra, be connected with the bushing type Foley catheter and introduce bladder again, air bag water filling 20-30ml, be 45 traction Foley catheter 3d along urethra direction and trunk, trailing weight is 0.5-1.0kg, to promote the urethra two ends involutory, trocar sheath is connected drainage bag respectively with catheter, and inserts the air bag of epidural catheter to nearly catheter from the conduction hole of trocar sheath.Postoperative is regularly from about 2 weeks of epidural catheter instillation flushing liquor, and reservation bushing type drain 8 all getting final product.
