Abstract
The utility model discloses an internal supporter drainage-tube for an ureter. The utility model is used by babies and newborns in ureter operations. The internal supporter drainage-tube for the ureter is characterized in that a drainage tube comprises a medical use hollow conduit which is divided into a neck part and a body part. The tube wall of the tube body of the drainage tube is provided with a plurality of single side holes, and a steel wire is arranged in the neck part of the drainage tube. The steel wire and the neck part are pressed to a solid by hot-pressing. The steel wire of the neck part is extended outwards, and the extend part is the tail part of the tube.
Description
This utility model relates to a kind of inner support drainage tube that is used for operation on ureter, particularly the inner support drainage tube in child, infant and the neonate operation on ureter.
In ureteral, common have: congenital malformation, and damage, calculus, tumor, inflammation and cause cicatrix etc., above-mentioned these diseases all can make patient's ureter become narrow, and therefore need undergo surgery treatment.Excision ureteropathy affected part branch could effectively be eradicated above-mentioned disease.
For not making the anastomotic stoma adhesion restenosis in the ureter after preventing to perform the operation, and it is smooth logical that patient is urinated, and must put into support tube in ureteral anastomotic stoma when operation is finished, is used for supporting anastomotic stoma, after the healing of kiss deutostoma, again this support tube is taken out in body.
The support tube that is adopted when carrying out above-mentioned operation at present mainly contains two kinds, and a kind of is the support arm pipe; Another kind is the inner support pipe, also claims pigtail pipe, two " J " pipe.
Referring to Fig. 1, Fig. 1 is the structure and the user mode sketch map of prior art support arm pipe.Shown in the figure: the 1-kidney, the 2-renal pelvis, the 3-ureter, the 4-anastomotic stoma, 5a-support tube, 5b-urinary drainage tube, described support arm pipe is to be made of a medical hollow tubing conductor, be provided with a plurality of one-sided conduction holes on catheter wall, described urinary drainage tube also is to be made of a medical hollow tubing conductor, and a terminal pipe of this pipe is provided with conduction hole.When the support arm pipe is adopted in operation, must while adapted urinary drainage tube.During use, one end of support arm pipe is put into ureter, then the other end stretches to external through ureter, kidney and operative incision, and an end of urinary drainage tube is inserted kidney underwent operative otch and is also stretched to external, therefore after the operation, patient's wound very easily infects, and wound healing time is also long, increases a lot of miseries to patient.The advantage of above-mentioned support arm pipe is a low price, and take out easily operation back: when getting pipe, need only choose outside patient body support arm pipe and urinary drainage tube of doctor gets final product.
Referring to Fig. 2, Fig. 2 is the structure and the user mode sketch map of the inner support pipe of prior art.Shown in the figure: the 1-kidney, the 2-renal pelvis, the 3-ureter, the 4-anastomotic stoma, 5c-inner support pipe, the 10-bladder, 11-urethra, described inner support pipe are to be made of a medical hollow tubing conductor, two ends of conduit are provided with conduction hole and it are curved pigtail shape.When the inner support pipe is adopted in operation, this Guan Jizuo support tube, the while is the double as urinary drainage tube again, like this, need not the adapted urinary drainage tube when operation.During use, be that whole inner support pipe is put within kidney, ureter and the bladder of human body, pipe does not communicate with extraneous, and therefore after the operation, patient's wound can not infect, and patients ' recovery is fast, and is painful few, but its shortcoming is a difficulty when getting pipe; Get when pipe, the doctor must take out the inner support pipe from patient's urethra, cystoscope that also must the adapted costliness when therefore getting pipe, even also must the adapted ureteroscope, could take out the inner support pipe.For minor child, particularly infant and neonate,, can't use the inner support pipe because of urethra is tiny.Another shortcoming of inner support pipe is to cost an arm and a leg, 600～800 yuan of every about RMB.
The purpose of this utility model is to provide a kind of in operation on ureter, and the scope of application is unrestricted, during operation pipe place and operation back pipe take out all very convenient, and the not susceptible endoureteral stent drainage tube of patients after surgery.
The purpose of this utility model is achieved in that this drainage tube comprises a medical hollow tubing conductor, it is characterized in that described conduit is divided into neck, body two parts, on described catheter shaft tube wall, be provided with a plurality of one-sided holes, in the neck tube of described conduit, be provided with a medical steel wire, this steel wire and cervical region catheter fever are pressed into a solid, and described cervical region steel wire is to external extension, and the extension is the afterbody of this pipe.
The utility model has the advantages that: because of the body of this drainage tube it both as support tube, double as urinary drainage tube again simultaneously.During operation, the doctor is ureter and a kidney of this tube body being put into human body, and the cervical region that passes through this pipe is to be communicated with the external world by the skin of afterbody steel wire by the people to external extension at last, so patients after surgery is difficult for infecting.Need to get when pipe behind the patients ' recovery, need only be by staying the external afterbody steel wire whole drainage tube of choosing, the dermal pore rapid closing is so it is also extremely convenient to get pipe.Since this pipe when getting without the human body urethra, so be specially adapted to child, young baby and the application of neonate in operation on ureter.Another advantage of this pipe is a low price, is convenient to promote the use of.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structure and the user mode sketch map of the support arm pipe of prior art.
Fig. 2 is the structure and the user mode sketch map of the inner support pipe of prior art.
Fig. 3 is a structure chart of the present utility model.
Fig. 4 is this utility model user mode sketch map.
Below in conjunction with Fig. 3, Fig. 4 describes concrete structure of the present utility model in detail.Shown in the figure: 1-kidney, 2-renal pelvis, 3-ureter, 4-anastomotic stoma, 5-inner support drainage tube, the body of 6-inner support drainage tube, the cervical region of 7-inner support drainage tube, the afterbody of 8-inner support drainage tube, 9-conduction hole, 10-human muscle and skin.
Referring to Fig. 3, Fig. 4, this drainage tube comprises a medical hollow tubing conductor, this conduit is divided into two parts, a part is the cervical region 7 of drainage tube, another part is the body 6 of drainage tube, the body tube wall of described conduit is provided with a plurality of one-sided conduction holes 9, be provided with a medical steel wire in the neck tube of described conduit, an end of this steel wire is located in the neck tube, and the other end of this steel wire extends a segment distance along die outside pipe in pipe, steel wire in the described neck tube can be spring-like, also can be straight steel wire, and be pressed into a solid that described this section steel wire that extends is the afterbody 8 of drainage tube outside pipe with the cervical region catheter fever.The profile of described cervical region solid can be cylindrical, or elliptical cylinder-shape, and this neck finish can be taper, taper shape, or streamlined.The specification of the length thickness of described drainage tube and body, neck, tail is to decide according to the practical application needs, and it can be:
