一种用于尿道会师的磁性探钢组件A magnetic steel detecting component for urethral rendezvous

【技术领域】【Technical field】

本发明属于医疗器械领域，尤其涉及一种用于尿道会师的磁性探钢组件。The invention belongs to the field of medical devices, and in particular relates to a magnetic detection steel assembly for urethral rendezvous.

【背景技术】【Background technique】

男性尿道既是排尿通道也是排精管道，起于膀胱颈内口，止于阴茎头尖端的尿道外口，成人长约18厘米，全程可分为三部：前列腺部(穿过前列腺的部分)、膜部(穿过尿生殖膈的部分，长约1.2厘米)和海绵体部(穿过尿道海绵体的部分)，临床上将前列腺部和膜部全称为后尿道，海绵体部称为前尿道。The male urethra is both a urination channel and a sperm evacuation channel. It starts from the inner opening of the bladder neck and ends at the outer urethral opening at the tip of the glans penis. The adult length is about 18 cm. The whole process can be divided into three parts: the prostate part (the part that passes through the prostate), Membranous part (the part that passes through the urogenital diaphragm, about 1.2 cm long) and cavernous part (the part that passes through the corpus cavernosum of the urethra). Clinically, the prostate part and the membranous part are called the posterior urethra, and the cavernous body part is called the anterior urethra. .

后尿道损伤多并发于骨盆骨折伤，当骨盆骨折致骨盆环前后径增大，左右径变小，或前后径变小，左右径增大时，致使前列腺部尿道与膜部尿道交接处撕裂或断裂，或因尿生殖膈撕裂并连同穿过其中的膜部尿道撕裂或断裂。Posterior urethral injury is often complicated by pelvic fracture injury. When the pelvic fracture causes the anteroposterior diameter of the pelvic ring to increase, the left and right diameters become smaller, or the anterior and posterior diameters become smaller and the left and right diameters increase, resulting in tearing at the junction of the prostatic urethra and the membranous urethra. Either rupture, or rupture or rupture of the urogenital diaphragm together with the membranous urethra passing through it.

现有技术中尿道会师的步骤：The steps of urethral rendezvous in the prior art:

第一步，术者用将尿道探钢从患者前尿道插入，术者食指经膀胱切口插入后尿道与尿道探钢会师，将由尿道外口插入的探子导入膀胱内。In the first step, the operator inserts the urethral probe from the patient's anterior urethra, the operator's index finger is inserted through the bladder incision to join the posterior urethra and the urethral probe, and the probe inserted from the external urethral orifice is introduced into the bladder.

第二步，通过尿道探钢置入导丝，在导丝引导下留置气囊尿管至膀胱内。In the second step, a guide wire is inserted through the urethral probe, and the balloon catheter is placed into the bladder under the guidance of the guide wire.

第三步，尿道牵引。用无菌等渗盐水充胀气囊，沿尿道方向牵引气囊导尿管，借牵引力使尿道两断端对合。The third step is urethral traction. The balloon is inflated with sterile isotonic saline, the balloon catheter is pulled along the urethra, and the two ends of the urethra are aligned by traction.

第四步，耻骨后放置橡皮管引流，关闭切口，并行耻骨上膀胱造口。In the fourth step, a rubber tube was placed behind the pubic bone for drainage, the incision was closed, and a suprapubic cystostomy was performed.

现有技术是一个传统的开放性手术，通过下腹正中切口进入膀胱前间隙并打开膀胱手术，手术的创伤较大，病人术后恢复较慢。The prior art is a traditional open operation, where the anterior bladder space is entered through a midline incision in the lower abdomen and the bladder is opened, the operation is more traumatic, and the patient recovers slowly after the operation.

【具体实施方式】【Detailed ways】

下面结合附图和具体实施方式对本发明进行详细说明。The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

本发明公开了一种用于尿道会师的磁性探钢组件，如图1所示，包括第一探钢1和第二探钢2，本发明属于一对组件，两者缺一不可，在手术的过程中需要两者相互配合才能完成尿道会师。第二探钢2代替了术者的手部伸入患者膀胱切口，避免造成创伤。因为探钢的直径小，而术者的手部粗，因此利用探钢肯定对患者的创伤小。The invention discloses a magnetic detection steel assembly for urethral realignment, as shown in FIG. 1 , including afirst detection steel 1 and asecond detection steel 2. The invention belongs to a pair of components, and the two are indispensable. In the process, the two need to cooperate with each other to complete the urethral union. Thesecond steel probe 2 replaces the operator's hand into the patient's bladder incision to avoid trauma. Because the diameter of the steel probe is small and the operator's hand is thick, the use of the steel probe must be less traumatic to the patient.

第一探钢1的两端分别为第一手持端3和第一磁性端4，第一磁性端4用于通过前尿道伸入，经过尿道球部到达尿道膜部断裂处，第一磁性端4的端部带有磁性；沿第一探钢1走向、第一探钢1内腔设置有供导丝穿过的通道。The two ends of thefirst probe steel 1 are the first hand-held end 3 and the firstmagnetic end 4, respectively. The firstmagnetic end 4 is used to extend through the anterior urethra, and reach the rupture of the urethral membrane through the bulb of the urethra. The end of 4 is magnetic; along the direction of thefirst probe steel 1, the inner cavity of thefirst probe steel 1 is provided with a channel for the guide wire to pass through.

第二探钢2的两端分别为第二手持端6和第二磁性端5，第二磁性端5用于通过膀胱颈内口，经尿道前列腺部伸入，到达尿道膜部断裂处，第二磁性端5的端部带有磁性，第一磁性端4与第二磁性端5用于相互吸引并相触形成一个整体，在第二探钢的引导下将第一探钢通过尿道断裂处进入膀胱，进而使得外界的导丝自第一手持端3进入第一探钢1内腔并穿过第一探钢1后到达膀胱内，留置导丝，撤出第一探钢和第二探钢，在导丝的引导下留置气囊尿管恢复尿道连续性完成尿道会师。The two ends of thesecond probe steel 2 are the second hand-held end 6 and the second magnetic end 5, respectively. The second magnetic end 5 is used to pass through the inner opening of the bladder neck, extend through the urethra and prostate, and reach the rupture of the urethral membrane. The end of the second magnetic end 5 is magnetic, the firstmagnetic end 4 and the second magnetic end 5 are used to attract each other and contact each other to form a whole, and the first probe steel is broken through the urethra under the guidance of the second probe steel Then, the external guide wire enters the inner cavity of thefirst probe 1 from the first hand-held end 3 and passes through thefirst probe 1 and then reaches the bladder, indwells the guide wire, and withdraws the first probe and the second probe. Exploring the steel, indwelling the balloon catheter under the guidance of the guide wire to restore the continuity of the urethra to complete the urethral rendezvous.

如图2所示，第二探钢2的第二磁性端5为球状，第二磁性端5为带有磁性的实心体，第一探钢1的第一磁性端4为球状，第一磁性端4为带有磁性的实心体，第一探钢1的实心体沿第一探钢1的轴线开设有导丝孔8，导丝孔8用于导丝通过。由于第一探钢1的第一磁性端4在第二探钢2的第二磁性端5引导的情况下，进入膀胱后，就需要从第一探钢1的第一手持端3插入导丝进入第一探钢1的内腔，然后导丝沿着第一探钢1的内腔自第一探钢1的第一磁性端4进入膀胱，留置导丝，将第一探钢退出，沿导丝置入气囊尿管恢复尿道的连续性，完成尿道会师术。As shown in FIG. 2 , the second magnetic end 5 of thesecond detection steel 2 is spherical, the second magnetic end 5 is a solid body with magnetism, the firstmagnetic end 4 of thefirst detection steel 1 is spherical, and the first magnetic Theend 4 is a solid body with magnetism. The solid body of thefirst probe steel 1 is provided with aguide wire hole 8 along the axis of thefirst probe steel 1 , and theguide wire hole 8 is used for the guide wire to pass through. Since the firstmagnetic end 4 of thefirst probe 1 is guided by the second magnetic end 5 of thesecond probe 2, after entering the bladder, the guide wire needs to be inserted from the first hand-held end 3 of thefirst probe 1 Enter the inner cavity of thefirst probe 1, then the guide wire enters the bladder from the firstmagnetic end 4 of thefirst probe 1 along the inner cavity of thefirst probe 1, indwelling the guide wire, withdraw the first probe, along the A guide wire was inserted into the balloon catheter to restore the continuity of the urethra, and the urethral rendezvous operation was completed.

由于将第一探钢1的第一磁性端4设置为实心，并且在实心部位开孔，而导丝穿过导丝孔8需要一定的时间，并且对术者的要求也较高，因此可以将第一探钢1的第一磁性端4设置为中空。Since the firstmagnetic end 4 of thefirst probe steel 1 is set to be solid, and a hole is made in the solid part, it takes a certain time for the guide wire to pass through theguide wire hole 8, and the requirements for the operator are also high, so it can be The firstmagnetic end 4 of thefirst probe steel 1 is set to be hollow.

如图3所示，第一探钢1为内部中空、两端开口的管状，第一探钢1的管内安装有推杆9，推杆9的长度与第一探钢1的长度相适应，推杆9靠近第一磁性端4的为内端，靠近第一手持端3为外端，推杆9的内端固定连接有磁性球体11、外端与第一手持端3螺纹连接，磁性球体11位于第一磁性端4的端部，用于与第二磁性端5相互吸引。通过这样设置就可以大大提高导丝进入膀胱的速度，避免因设置导丝孔8导致导丝穿过速度慢。通过设置磁性球体11还可以增加第一探钢1自前尿道进入患者尿道时，患者的舒服度，因为磁性球体11是球状，使得第一探钢1的第一磁性端4为半球状，进而在进入患者尿道时摩擦力较小，避免患者不适。As shown in FIG. 3 , thefirst probe steel 1 is a tubular shape with a hollow interior and open ends at both ends. Apush rod 9 is installed in the tube of thefirst probe steel 1 , and the length of thepush rod 9 is adapted to the length of thefirst probe steel 1 . The inner end of thepush rod 9 is close to the firstmagnetic end 4, and the outer end is close to the first hand-held end 3. The inner end of thepush rod 9 is fixedly connected with amagnetic ball 11, and the outer end is threadedly connected with the first hand-held end 3. 11 is located at the end of the firstmagnetic end 4 for attracting with the second magnetic end 5 . By setting in this way, the speed of the guide wire entering the bladder can be greatly improved, and the slow passing speed of the guide wire due to the setting of theguide wire hole 8 can be avoided. By arranging themagnetic sphere 11, the comfort of the patient when thefirst steel probe 1 enters the patient's urethra from the anterior urethra can also be increased. There is less friction when entering the patient's urethra to avoid patient discomfort.

除设置推杆9外，还有一种设计方式，因为男性尿道非直线的，因此推杆9在实施的过程中容易受到限制，因此还有另外一种设计可以很好的解决这个问题，即在第一探钢1的第一磁性端4设置托环10，第一探钢1为内部中空、两端开口的管状，如图4所示，第一磁性端4外沿向内凹陷形成环状的托环10；第一探钢1内设置有弹性件，弹性件的内端固定连接有磁性球体11、外端卡在第一手持端3，托环10用于卡住磁性球体11，使得磁性球体11位于第一探钢1内腔外，磁性球体11位于第一磁性端4的端部，用于与第二磁性端5相互吸引。在进入男性尿道时，磁性球体11位于托环10之外，减小探钢进入男性尿道时的阻力，当第一探钢1的第一磁性端4进入膀胱后，通过拉动弹性件可以将磁性球体11从托环10之外拉回第一探钢1内腔，并从第一探钢1内腔抽出，然后在第一探钢1的第一手持端3放入导丝。In addition to setting thepush rod 9, there is another design method, because the male urethra is not straight, so thepush rod 9 is easily restricted in the process of implementation, so there is another design that can solve this problem well, that is, in the The firstmagnetic end 4 of thefirst probe steel 1 is provided with asupport ring 10, and thefirst probe steel 1 is a tubular shape with a hollow interior and two open ends. As shown in FIG. 4, the outer edge of the firstmagnetic end 4 is recessed inward to form a ring shape Thesupport ring 10; thefirst probe steel 1 is provided with an elastic member, the inner end of the elastic member is fixedly connected with amagnetic sphere 11, and the outer end is clamped on the first hand-held end 3, and thesupport ring 10 is used to clamp themagnetic sphere 11, so that Themagnetic sphere 11 is located outside the inner cavity of thefirst probe steel 1 , and themagnetic sphere 11 is located at the end of the firstmagnetic end 4 for attracting with the second magnetic end 5 . When entering the male urethra, themagnetic ball 11 is located outside thesupport ring 10, which reduces the resistance of the steel probe when it enters the male urethra. Theball 11 is pulled back into the inner cavity of thefirst probe steel 1 from the outside of thesupport ring 10 , and pulled out from the inner cavity of thefirst probe steel 1 , and then a guide wire is put into the first hand-held end 3 of thefirst probe steel 1 .

上述的三种设计在放入导丝时，都需要将第一探钢1内的磁性球体11抽出，或者需要导丝通过很小的孔，操作较为复杂，因此通过下面的设计可以一次性的完成，无须多次的复杂操作。The above three designs all need to pull out themagnetic sphere 11 in thefirst probe steel 1 when the guide wire is put in, or the guide wire needs to pass through a very small hole, and the operation is more complicated. Therefore, the following design can be used at one time. Completed, no need for multiple complex operations.

如图5所示，第一探钢1为内部中空、两端开口的管状，沿第一探钢1的纵切线一体连接有隔板13，隔板13用于将第一探钢1内腔分割成两个，两个内腔为用于导丝通过的导丝内腔7和用于磁性球体11通过的球体内腔12。As shown in FIG. 5 , thefirst probe steel 1 is a tubular shape with a hollow interior and open ends at both ends, and apartition 13 is integrally connected along the longitudinal tangent of thefirst probe steel 1 , and thepartition plate 13 is used to separate the inner cavity of thefirst probe steel 1 Divided into two, the two lumens are the guide wire lumen 7 for the guide wire to pass through and the sphericalinner lumen 12 for themagnetic ball 11 to pass through.

导丝内腔7内安装有推杆9，推杆9的长度与第一探钢1的长度相适应，推杆9靠近第一磁性端4的为内端，靠近第一手持端3为外端，推杆9的内端固定连接有磁性球体11、外端与第一手持端3螺纹连接，磁性球体11位于第一磁性端4的端部，用于与第二磁性端5相互吸引。通过将第一探钢1的内腔分割成两个内腔可以很快的将导丝伸入膀胱。Apush rod 9 is installed in the inner cavity 7 of the guide wire. The length of thepush rod 9 is adapted to the length of thefirst probe steel 1. Thepush rod 9 is the inner end close to the firstmagnetic end 4, and the outer end close to the first hand-held end 3. The inner end of thepush rod 9 is fixedly connected with amagnetic ball 11 , and the outer end is threadedly connected with the first hand-held end 3 . The guide wire can be quickly inserted into the bladder by dividing the inner cavity of thefirst probe steel 1 into two inner cavities.

除设置推杆9外，还有一种设计方式，因为男性尿道非直线的，因此推杆9在实施的过程中容易受到限制，因此还有另外一种设计可以很好的解决这个问题，即在球体内腔12靠近第一磁性端4设置托环10，球体内腔12的第一磁性端4外沿向内凹陷形成环状的托环10；球体内腔12内设置有弹性件，弹性件靠近第一磁性端4的为内端，靠近第一手持端3为外端，弹性件的内端固定连接有磁性球体11、外端卡在第一手持端3，托环10用于卡住磁性球体11，使得磁性球体11位于球体内腔12外，磁性球体11位于第一磁性端4的端部，用于与第二磁性端5相互吸引。该设计和第一探钢1为一个腔体时的原理一样。In addition to setting thepush rod 9, there is another design method, because the male urethra is not straight, so thepush rod 9 is easily restricted in the process of implementation, so there is another design that can solve this problem well, that is, in the Theinner cavity 12 of the sphere is provided with asupport ring 10 near the firstmagnetic end 4, and the outer edge of the firstmagnetic end 4 of theinner cavity 12 of the sphere is recessed inward to form a ring-shapedsupport ring 10; theinner cavity 12 of the sphere is provided with an elastic member, and the elastic member The inner end is close to the firstmagnetic end 4, the outer end is close to the first hand-held end 3, the inner end of the elastic member is fixedly connected with amagnetic ball 11, the outer end is clamped on the first hand-held end 3, and thesupport ring 10 is used for clamping Themagnetic sphere 11 is arranged so that themagnetic sphere 11 is located outside theinner cavity 12 of the sphere, and themagnetic sphere 11 is located at the end of the firstmagnetic end 4 for attracting with the second magnetic end 5 . The design is the same as the principle when thefirst steel probe 1 is a cavity.

在上述的各种设计中，都需要将第二探钢2的第二磁性端5的内径小于第一探钢1的第一磁性端4的内径。因为这样可以将第二探钢2的第二磁性端5尽可能的接近并伸入第一探钢1的第一磁性端4，保证导丝的顺利通过。In the above-mentioned various designs, the inner diameter of the second magnetic end 5 of thesecond probe steel 2 needs to be smaller than the inner diameter of the firstmagnetic end 4 of thefirst probe steel 1 . Because in this way, the second magnetic end 5 of thesecond detection steel 2 can be as close as possible to and extended into the firstmagnetic end 4 of thefirst detection steel 1 to ensure the smooth passage of the guide wire.

本发明的使用方法为：The using method of the present invention is:

通过第一探钢和第二探钢的配合方便术者进行操作，只需在患者下腹正中切开一个微小的开口，并将第二探钢伸入切口，然后让第一探钢和第一探钢相互吸引并相触，在第二探钢的引导下带动第一探钢进入膀胱，然后将导丝在第一探钢的引导下留置尿管完成尿道会师，本发明能够通过微创的方式快速完成尿道会师，避免开刀手术，患者术后恢复快。The cooperation of the first and second steel probes is convenient for the operator to operate. It is only necessary to make a small opening in the middle of the patient's lower abdomen, and insert the second probe into the incision, and then let the first and second probes be inserted into the incision.
