一种经脐软式内窥镜手术的腹腔穿刺装置A paracentesis device for transumbilical flexible endoscopic surgery

技术领域technical field

本实用新型涉及医疗器械技术领域，具体地涉及一种经脐软式内窥镜手术的腹腔穿刺装置。The utility model relates to the technical field of medical instruments, in particular to an abdominal puncture device for transumbilical flexible endoscopic surgery.

背景技术Background technique

经脐入路手术，又称为经脐入路内镜或腹腔镜手术(transumbilical endoscopicsurgery，TUES)，是指将器械和腹腔镜经脐部的套管置入腹腔进行手术的技术。作为一项新的技术，许多作者用不同的术语进行描述，如单孔手术或经脐单孔手术。经脐入路手术的优势在于更好的美观效果和更轻的手术创伤。由于脐部是一天然皱褶部位，手术后几乎看不到手术痕迹，保留了腹壁的完整性。脐部组织相对较薄，经过脐部的手术器械对腹壁损伤更轻。所以这一技术达到了更加美观、更加微创的效果。目前，经脐软式内窥镜(如胃镜、肠镜)手术，腹壁穿刺针大部分采用腹腔镜(硬镜，前端无弯曲部)的穿刺套管。但是，套管不适于软式内窥镜的操作。腹腔镜穿刺套管卡住软式内窥镜前端的弯曲部，导致软式内窥镜无法自由弯曲、改变进入腹腔方向。Transumbilical approach surgery, also known as transumbilical endoscopic or laparoscopic surgery (transumbilical endoscopic surgery, TUES), refers to the technique of inserting instruments and laparoscopic cannula through the umbilicus into the abdominal cavity for surgery. As a new technique, many authors describe it using different terms, such as single-port surgery or transumbilical single-port surgery. The advantages of the transumbilical approach lie in better aesthetic results and less surgical trauma. Since the umbilicus is a natural fold, almost no surgical traces can be seen after the operation, and the integrity of the abdominal wall is preserved. The umbilical tissue is relatively thin, and surgical instruments passing through the umbilicus will cause less damage to the abdominal wall. So this technique achieves a more aesthetically pleasing, less invasive effect. At present, in transumbilical flexible endoscope (such as gastroscope, enteroscope) operation, most of abdominal wall puncture needles adopt the puncture sleeve of laparoscope (rigid mirror, front end without bending portion). However, the sleeve is not suitable for the manipulation of flexible endoscopes. The laparoscopic puncture sleeve clamps the bending part of the front end of the flexible endoscope, causing the flexible endoscope to be unable to bend freely and change the direction of entering the abdominal cavity.

具体实施方式Detailed ways

实施例1Example 1

本实用新型的具体实施例，参照图1至图3，以及图5，一种经脐软式内窥镜手术的腹腔穿刺装置，包括鞘管1、棱针2以及导丝3。其中该导丝3为细长软质的针丝。For specific embodiments of the present invention, referring to FIGS. 1 to 3 , and FIG. 5 , a peritoneal puncture device for transumbilical flexible endoscopic surgery includes asheath tube 1 , a ribbedneedle 2 and aguide wire 3 . Wherein theguide wire 3 is an elongated soft needle wire.

该棱针2包括一端部21以及一本体22，其中端部21的直径大于本体22的直径，本体22的另一端为尖端24，其为三棱形以便于穿过脐部，所述的三棱形即该尖端为三个棱面组合而成，尖端的横截面为三角形。导丝通道23在轴向上贯通本体22和端部21、以及尖端24。The ribbedneedle 2 includes anend 21 and abody 22, wherein the diameter of theend 21 is greater than the diameter of thebody 22, and the other end of thebody 22 is atip 24, which is triangular in shape so as to pass through the navel, and the three The prismatic shape means that the tip is composed of three facets, and the cross section of the tip is triangular. The guide wire channel 23 runs through thebody 22 , theend portion 21 and thetip 24 in the axial direction.

该鞘管1为中空状，轴向上设有恰容纳棱针2的本体22的通道15。该鞘管1由对称的左半套筒11以及右半套筒12组成，组合之后形成本体13以及喇叭状的端部14。Thesheath tube 1 is hollow and axially provided with achannel 15 just for accommodating thebody 22 of the ribbedneedle 2 . Thesheath 1 is composed of a symmetrical left half-sleeve 11 and a right half-sleeve 12 , which form abody 13 and a trumpet-shapedend 14 after combination.

参见图5至图10，使用时，导丝3穿入棱针2中，棱针2再插入鞘管1中。先将导丝3通过脐部穿刺进入腹腔4(图5)，然后棱针2和其外的鞘管1一起沿着导丝3插入腹腔，这样尖锐的棱针2顺利地穿过腹壁，并且不会损伤肠管(图6)。随后，拔出导丝3(图7)，，再将棱针2拔出，只留下鞘管1(图8)，软式内窥镜5经鞘管1进入腹腔(图9)，将鞘管1的左半套筒11以及右半套筒12分开并拔除1，这样软式内窥镜在腹腔活动及操作更灵活(图10)。Referring to FIGS. 5 to 10 , during use, theguide wire 3 is inserted into the ribbedneedle 2 , and the ribbedneedle 2 is then inserted into thesheath tube 1 .
