Abstract
The invention discloses an olecranon type urethral dilator with an openable sheath. The olecranon type urethral dilator comprises a dilator body, a high-pressure ball capsule and the openable sheath. The upper end of the dilator body is provided with a finger pulp groove. The lower end of the dilator body is provided with an olecranon type bend. A guide-in hole penetrating through the two ends of the dilator body is formed in the dilator body. The high-pressure ball capsule is arranged on the dilator body and located on the upper portion of the olecranon type bend. The included angle between the tangential direction of the olecranon type bend and the length direction of the dilator body is 30-45 degrees. The openable sheath is arranged outside the dilator body. The olecranon type urethral dilator is provided with the openable sheath, the dilator body can be guided by a guide wire in the guide-in hole in the dilator body when placed in, the openable sheath can be placed into the bladder under the guide of the dilator body after the urethra is sequentially dilated, and a catheter is easily guided into the bladder. Operation is easy and convenient, hemorrhage during operation, injuries and other complications can be reduced, and urethral stricture surgery treatment difficulty and errors are reduced.
Description
Technical field
The present invention relates to a kind of with can the olecranon type divulsor of strip off sheath.
Background technology
At present, Urology Surgery treatment urethral stricture, usually use metal dilator or disposable S type divulsor, metal divulsor usually needs again to sterilize after using, sterile products likely causes bacterial infection possibility again, and cut in the middle of metal dilator and do not design seal wire access aperture, easily cause in art damage produce urethra via.And although disposable S type divulsor feels to meet male urethra curved design from design concept, but design unreasonable in Clinical practice reality, because male genital organ is mentioned by male urethra front curve clinicist in operation just disappear, there is no need completely to be designed to S type, S type divulsor design material is too soft, be difficult in clinical manipulation control, easily cause injury of urethra, we observe after urethral stricture has been expanded through a large amount of clinical practice usually has catheter to insert the patient of difficulty, extremely perplex clinicist, when we run into this kind of situation in clinical, again catheter per urethra is inserted bladder after usually using homemade olecranon sample hard copper silk or aluminium wire to insert catheter, but it is long that this mode catheter imports the time, inefficiency, work is inconvenient.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the problem that the present invention solves is: again catheter per urethra is inserted bladder after inserting catheter by homemade olecranon sample hard copper silk or aluminium wire in prior art, but it is long that this mode catheter imports the time, inefficiency, work is inconvenient.
For solving the problem, the technical scheme that the present invention takes is as follows:
With can the olecranon type divulsor of strip off sheath, comprise dilator body, high pressure sacculus, can strip off sheath; The upper end of described dilator body is provided with and refers to that abdomen is recessed, and the lower end of dilator body is provided with olecranon type elbow; Described dilator body interior is provided with the entrance hole running through its two ends; Described high pressure sacculus is arranged on dilator body, is positioned at the top of olecranon type elbow; Angle angle between the tangential direction of described olecranon type elbow and the length direction of dilator body is 30 ~ 45 degree; Described can be located at the outside of dilator body by strip off sheath.
Further, the angle angle between the tangential direction of described olecranon type elbow and the length direction of dilator body is 40 degree.
Further, the length of described dilator body is 24 ~ 26cm; The length of described high pressure sacculus is 7 ~ 9cm.
Further, described high pressure sacculus is made up of nylon or Pebax material.
Beneficial effect of the present invention
1. be equipped with can strip off sheath in the present invention, can be guided by the seal wire in its entrance hole when dilator body is inserted, bladder can be inserted by strip off sheath under dilator body guides after the expansion of urethra order, easily catheter is inserted bladder, easy and simple to handle, the complication such as intraoperative hemorrhage, damage can be reduced like this occur, reduce difficulty and the error of operation urethral stricture treatment.Olecranon type elbow is arranged in dilator body lower end of the present invention, and the angle angle controlled between olecranon type elbow tangential direction and the length direction of dilator body is 30 ~ 45 degree, according to the physiological bending of human urethra, reaches perfect coupling.High pressure sacculus is arranged on dilator body, sequentially can expand, first seal wire can be inserted intravesical through Microendoscopic per urethra is narrow, guide through seal wire and high pressure sacculus olecranon type divulsor is inserted any narrow positions row expansion of urethra, easy and simple to handle, can dilating urethra be narrow rapidly.The thumb that refers to that abdomen is recessed when performing the operation for operator being set gripping, having and referring to that abdomen is recessed, the thumb phase of inserting can better controlling party to, do not allow dilator unrest veer, in order to avoid cause urethrorectal damage etc.
2. the length of dilator body of the present invention is 24 ~ 26cm, and the length of high pressure sacculus is 7 ~ 9cm.Similar high pressure sacculus occupies the length of dilator body 1/3rd, and such vibrational power flow is convenient to any narrow positions row expansion of urethra, and extended area is large, and speed is fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of dilator body of the present invention.
Fig. 2 is that the present invention is equipped with can the structural representation of strip off sheath.
Detailed description of the invention
Below in conjunction with accompanying drawing, content of the present invention is described in further detail.
As shown in Figure 1, a kind of with can the olecranon type divulsor of strip off sheath, comprise dilator body 1, high pressure sacculus 2.The upper end of dilator body 2 is provided with and refers to abdomen recessed 11, to arrange when referring to that abdomen recessed 11 perform the operation for operator thumb gripping, and has to refer to an abdomen recessed 11, the thumb phase of inserting can better controlling party to, do not allow dilator unrest veer, in order to avoid cause urethrorectal damage etc.The lower end of dilator body 1 is provided with olecranon type elbow 12.Dilator body 1 inside is provided with the entrance hole running through its two ends.High pressure sacculus 2 is arranged on dilator body 1, is positioned at the top of olecranon type elbow 12.As shown in Figure 2, the included angle A angle between the tangential direction of olecranon type elbow 12 and the length direction of dilator body 1 is 30 ~ 45 degree, and the included angle A angle between the tangential direction of the present embodiment preferred olecranon type elbow 12 and dilator body 1 length direction is 40 degree.Included angle A angle between olecranon type elbow 12 tangential direction and dilator body 1 length direction is set according to the physiological bending of human urethra, reaches perfect coupling.The present invention is arranged can strip off sheath 3, can be located at the outside of dilator body 1 by strip off sheath 3.The present invention is equipped with can strip off sheath 3, can be guided by the seal wire in its entrance hole when dilator body 1 is inserted, bladder can be inserted by strip off sheath 3 under dilator body 1 guides after the expansion of urethra order, easily catheter is inserted bladder, easy and simple to handle, the complication such as intraoperative hemorrhage, damage can be reduced like this occur, reduce difficulty and the error of operation urethral stricture treatment.Further preferably, in the present embodiment, the length of dilator body 1 is 25cm, and the length of high pressure sacculus 2 is 8cm.Similar high pressure sacculus 2 occupies the length of dilator body 1/1st three, and such vibrational power flow is convenient to any narrow positions row expansion of urethra, and extended area is large, and speed is fast.Further preferably, described high pressure sacculus 2 is made up of nylon or Pebax material.
