尿潴留为泌尿外科常见急症，需急诊行导尿治疗，而对于前列腺肥大、外伤、肿瘤等所致尿道狭窄而引起的尿潴留患者，还需留置导尿管。而临床上目前所使用的导尿管多为天然橡胶、硅橡胶或聚氯乙烯（PVC）材质的导尿管，存在一定的柔韧性，对于尿道狭窄的患者导尿管往往不能插入，导致导尿失败。为此，需行尿道扩张术，而临床上所用的尿道探子多为金属探子，在扩张的过程中，由于尿道生理弯曲的存在，以及扩张的不可视性，扩张风险较大，易形成假道，损伤尿道，增加病人的痛苦，因而对操作者的要求很高。 Urinary retention is a common emergency in urology, which requires emergency catheterization. For patients with urinary retention caused by urethral stricture caused by prostatic hypertrophy, trauma, tumors, etc., an indwelling catheter is also required. However, most of the catheters currently used clinically are made of natural rubber, silicone rubber or polyvinyl chloride (PVC), which have certain flexibility. For patients with urethral stricture, the catheter cannot be inserted often, resulting in Urinary failure. For this reason, urethral dilation is required, and most of the urethral probes used clinically are metal probes. During the dilation process, due to the existence of the physiological curvature of the urethra and the invisibility of dilation, the risk of dilation is relatively high, and false tracts are likely to be formed. , damage the urethra, and increase the pain of the patient, so the requirements for the operator are very high.

具体实施方式 Detailed ways
如图所示，一种用于留置导尿管的尿道探子，包括不锈钢探子本体，探子本体为本体Ⅰ1和本体Ⅱ2对接后形成的圆筒状壳体，本体Ⅰ1和本体Ⅱ2的截面均呈半圆形，所述本体Ⅰ1的两个对接端均设置有菱形卡条3，菱形卡条3沿本体Ⅰ1的长度方向设置，所述本体Ⅱ2的两个对接端均设置有与菱形卡条3形状相互配合的菱形卡槽4，且菱形卡槽4远离本体Ⅱ2一端具有与本体Ⅰ1的壁厚相适应的缺口5，本体Ⅰ1和本体Ⅱ2对接时，本体Ⅰ1的菱形卡条3置入本体Ⅱ2的菱形卡槽4内。所述菱形卡槽4的一端通过挡板6封闭，4的另一端敞口设置。 As shown in the figure, a urethral probe for indwelling urinary catheters includes a stainless steel probe body. The probe body is a cylindrical shell formed by docking the body I1 and the body II2. The cross sections of the body I1 and the body II2 are both half. It is circular, and the two butt ends of the body I1 are provided with diamond-shaped clips 3, which are arranged along the length direction of the body I1, and the two butt ends of the body II2 are provided with diamond-shaped clips 3. The diamond-shaped card slot 4 that cooperates with each other, and the end of the diamond-shaped card slot 4 away from the body II2 has a gap 5 that is suitable for the wall thickness of the body I1. Inside card slot 4. One end of the diamond-shaped slot 4 is closed by a baffle 6, and the other end of the 4 is open.
本发明尿道探子的使用方法为：先将需要留置的导尿管7置于本体Ⅰ1的半圆形空腔内，导尿管7的头端和尾端均伸出本体Ⅰ1设置，然后将本体Ⅱ2与本体Ⅰ1对接，对接的方法是顺着本体Ⅱ2的菱形卡槽4将本体Ⅰ1的菱形卡条3置入其中，对接后导尿管7处于被挤压状态，使得导尿管7与尿道探子8的内部紧密接触，尽可能减少导尿管7与尿道探子8之间的相对运动，然后将外部包裹有尿道探子8的导尿管7插入患者的尿道内，并前进至预定位置，然后抽出本体Ⅱ2，再抽出本体Ⅰ1，实现导尿管的留置，本发明的尿道探子，能够实现在扩张尿道的同时，进行导尿管的留置，既增加了现有导尿管的硬度，并且还巧妙利用了导尿管尖端的韧性扩张尿道，避免了现有金属探子尖端对尿道的损伤及假道的形成。 The method of using the urethral probe of the present invention is as follows: first place the catheter 7 that needs to be indwelled in the semicircular cavity of the body I1, the head end and the tail end of the catheter 7 protrude from the body I1, and then place the body II2 is docked with the body I1, and the docking method is to put the diamond-shaped clip 3 of the body I1 along the diamond-shaped slot 4 of the body II2. After docking, the catheter 7 is in a squeezed state, so that the catheter 7 and the urethra The inside of the probe 8 is in close contact, and the relative movement between the urinary catheter 7 and the urethral probe 8 is reduced as much as possible, and then the urinary catheter 7 wrapped with the urethral probe 8 is inserted into the patient's urethra and advanced to a predetermined position, and then Pull out the main body II2, and then pull out the main body I1 to realize the indwelling of the urinary catheter. The urethral probe of the present invention can realize the indwelling of the urinary catheter while expanding the urethra, which not only increases the hardness of the existing urinary catheter, but also The toughness of the tip of the catheter is cleverly used to expand the urethra, avoiding the damage of the tip of the existing metal probe to the urethra and the formation of a false tract.
