The head airbag 200 may be configured in a bowl shape gradually widened from the rear to the front, as shown in fig. 1; the head airbag 200 may be configured in a cup shape gradually widened from the rear to the front, as shown in fig. 5; the head airbag 200 may be configured in a pear shape that gradually widens from back to front, as shown in fig. 3; the head airbag 200 may be provided in a drop shape gradually widened from the rear to the front as shown in fig. 4. The shape of the head airbag 200 can conform to the shape that the foreskin gradually narrows towards the position far away from the glans penis, so that the head airbag 200 and the foreskin can be conveniently fixed relatively, and the use requirement of the airbag type dilatation catheter is met.
Referring to fig. 1, after the head airbag 200 is expanded, the front end of the head airbag 200 is provided with an arc concave surface 210 which is recessed backwards, the arc concave surface 210 is used for being abutted to the glans penis of a patient, which is beneficial to increasing the contact area between the head airbag 200 and the glans penis, and along with the expansion of the head airbag 200, the glans penis is embedded into the head airbag 200, which is beneficial to enabling the head airbag 200 to be partially clamped between the glans penis and the foreskin, thereby separating the adhesion between the foreskin and the glans penis and meeting the use requirement of the foreskin expansion operation.
The sleeve airbag 400 is arranged at one end close to the head airbag 200, and is concrete, after the sleeve airbag 400 and the head airbag 200 are expanded, the front end of the sleeve airbag 400 is abutted to the rear end of the head airbag 200, so that the gap between the front end and the rear end of the head airbag 400 is reduced, and the sleeve airbag 400 is beneficial to ensuring that the head airbag 200 is clamped at the inner side of a preputial opening of a patient, at least part of the sleeve airbag 400 is positioned at the inner side of the preputial opening of the patient, along with the expansion of the sleeve airbag 400, the preputial opening of the patient can be gradually expanded, so that the preputial is turned outwards to expose the state of a coronary sulcus, the head of the penis and the urethral opening of the patient are exposed, so that the cleaning of preputial scales is realized, and the treatment of phimosis and the patient is realized.
During clinical operation, the user can realize the expansion of foreskin many times through sleeve pipe gasbag 400, and can keep certain time at every expansion to realize progressively expanding to patient's foreskin, after patient's prepuce mouth expands to certain degree, can realize the eversion of foreskin naturally, reach the treatment to foreskin and phimosis patient. The mode of the sleeve airbag 400 expanding for a plurality of times is beneficial to avoiding the problems of the patients of skin opening tearing, scar generation, great pain of the sick children, long recovery period, easy relapse and the like caused by one-time violent expansion, and accords with the concept of non-invasive surgery.
It should be noted that the length of the sleeve airbag 400 is set so that when the head airbag 200 abuts against the inner side of the foreskin, the front end and the rear end of the sleeve airbag 400 are respectively located at the inner side and the outer side of the foreskin opening, thereby ensuring that the caliber of the foreskin opening can be expanded along with the expansion of the sleeve airbag 400.
Further preferably, considering that most patients who perform foreskin dilatation surgery are children, the expansible degree of foreskin of common children, the elasticity of foreskin of children and other factors, the maximum expansion width of the head airbag 200 can be set to be 1.0cm to 2.0cm, namely, after the head airbag 200 is expanded, the maximum width of the head airbag 200 extending along the radial direction of the catheter body 100 is 1.0cm to 2.0cm, so that the head airbag 200 is clamped on the inner side of the foreskin of the patient, the function of relatively fixing the airbag type expansion catheter and the foreskin of the patient is realized, and the follow-up effective expansion of the perikin opening of the patient is favorably realized.
Further preferably, the balloon dilatation catheter further comprises a first one-way valve 510, a second one-way valve 520, a first inflator and a second inflator; the first check valve 510 is disposed between the first inflator and the first inflation pipeline 310, and is respectively communicated with the first inflator and the first inflation pipeline 310, and the conduction direction of the first check valve 510 is a direction toward the head airbag 200; the second check valve 520 is disposed between the second inflator and the second inflation tube 320, and is respectively communicated with the second inflator and the second inflation tube 320, the conduction direction of the second check valve 520 is the direction toward the sleeve airbag 400, and a user can inflate the first inflation tube 310 and the second inflation tube 320 through the first inflator and the second inflator, so as to expand the head airbag 200 and the sleeve airbag 400.
After the operation is completed, the first one-way valve 510 and the second one-way valve 520 can be pulled out, so that the first inflation pipeline 310 and the second inflation pipeline 320 are deflated, and then the head balloon 200 and the sleeve balloon 400 are contracted, so as to realize the function of pulling out or recycling the balloon dilatation catheter.
First pump and second pump can adopt the air pump of electrodynamic type to the realization is favorable to realizing the slow expansion to the patient's foreskin to the expansion of continuously aerifing of head gasbag 200 and sleeve pipe gasbag 400, and being provided with of first check valve 510 and second check valve 520 does benefit to the gas tightness of guaranteeing head gasbag 200 and sleeve pipe gasbag 400, is favorable to keeping the expansion shape of head gasbag 200 and sleeve pipe gasbag 400, satisfies the user demand of foreskin expansion operation.
