Description
技术领域 technical field
本发明涉及一种穿刺套管，尤其涉及一种在进行胆囊取石或胆囊取息肉手术时用于进行胆囊穿刺的穿刺套管。 The invention relates to a puncture sleeve, in particular to a puncture sleeve used for gallbladder puncture during gallbladder stone extraction or gallbladder polyp extraction. the
背景技术 Background technique
保留胆囊切开取石(或息肉摘除)手术是近年来开展的新式微创手术，因为其创伤小、恢复快，治疗胆囊结石(或息肉摘除)的同时又保留胆囊功能，因此在临床上得到广泛应用。 Gallbladder-preserving stone removal (or polyp removal) surgery is a new type of minimally invasive surgery in recent years, because of its small trauma, quick recovery, and the treatment of gallbladder stones (or polyp removal) while preserving gallbladder function, it is widely used in clinical practice. application. the
目前微创内镜保但手术式有多种，主要有小切口内镜保但取石(或息肉摘除)术和腹腔镜辅助的小切口内镜保但取石(或息肉摘除)术。为保证手术效果，手术过程在胆囊作口、取石(息肉)和胆囊切口修复等操作都要融入微创的理念和有利于胆囊功能的维持与恢复的原则。小切口保胆取石(息肉摘除)术适用于胆囊底位于肋弓下、腹壁比较薄的患者。这种术式需B超确定胆囊底位置，可持续硬膜外麻醉或全身麻醉下在肋缘下腹壁切开，将胆囊底提到腹壁切口，直视下取石或摘除息肉。此操作具有方便、快捷、腹腔内较少积液、费用少。腹腔镜辅助的小切口保胆取石手术使用范围如上，但术前无需性胆囊底B超定位。在腹腔镜下找到胆囊，在明视下电灼切开胆囊底部，然后在胆道经的观察下用网篮取出结石或息肉，最后用可吸收丝线缝闭胆囊切口。但是这种方法往往容易造成胆汁和使用胆囊镜时所用的生理盐水外溢和污染腹腔，增加清洗腹腔的麻烦和手术时间。 At present, there are many kinds of minimally invasive endoscopic surgery, mainly small-incision endoscopic stone removal (or polypectomy) and laparoscopic-assisted small-incision endoscopic stone removal (or polypectomy). In order to ensure the effect of surgery, the concept of minimally invasive surgery and the principle of maintaining and recovering gallbladder function should be incorporated into operations such as gallbladder opening, stone removal (polyp) and gallbladder incision repair. Small incision gallbladder-preserving stone removal (polypectomy) is suitable for patients whose gallbladder fundus is located under the costal arch and whose abdominal wall is relatively thin. This operation requires B-ultrasound to determine the position of the gallbladder fundus, and can be used under continuous epidural anesthesia or general anesthesia to make an incision in the abdominal wall under the costal margin, lift the gallbladder fundus to the abdominal wall incision, and remove stones or polyps under direct vision. This operation is convenient, quick, less fluid in the abdominal cavity, and less expensive. The scope of laparoscopic-assisted small incision gallbladder-preserving surgery is as above, but preoperative B-ultrasound positioning of the gallbladder fundus is not required. The gallbladder was found under laparoscopy, and the bottom of the gallbladder was incised by electrocautery under bright vision, and then stones or polyps were removed with a mesh basket under the observation of the biliary meridian, and finally the gallbladder incision was closed with absorbable silk suture. However, this method tends to easily cause bile and normal saline used in cholecystoscopy to overflow and contaminate the abdominal cavity, which increases the trouble of cleaning the abdominal cavity and the operation time. the
另外，在小切口内镜保但取石(或息肉摘除)术和腹腔镜辅助的小切口内镜保但取石(或息肉摘除)术的手术过程中，将胆囊底提到腹壁切口需要双线缝合胆囊底部悬吊胆囊，操作难度大，延长了整个手术的时间，加大了病人的负担。 In addition, during small-incision endoscopic stone removal (or polypectomy) and laparoscope-assisted small-incision endoscopic stone removal (or polypectomy), lifting the gallbladder fundus to the abdominal wall incision requires double suture The gallbladder is suspended from the bottom of the gallbladder, which is difficult to operate, prolongs the time of the entire operation, and increases the burden on the patient. the
发明内容Contents of the invention
鉴于此，本发明提供一种新的用于进行胆囊穿刺的穿刺套管。利用本发明所提供的穿刺套管进行保胆手术时，可不用进行缝合胆囊底部和悬吊胆囊的操作，大大缩短了手术的时间，并使得手术操作更加方便。 In view of this, the present invention provides a new puncture sleeve for gallbladder puncture. When the puncture sleeve provided by the present invention is used for gallbladder-preserving surgery, the operation of suturing the bottom of the gallbladder and suspending the gallbladder is unnecessary, which greatly shortens the operation time and makes the operation more convenient. the
本发明所提供的穿刺套管包括所述穿刺套管包括用于夹紧胆囊壁的夹持部件。例如，所述穿刺套管可以包括依次套接的芯针、内套管、外套管，所述内套管的外周面上设置有环形凸缘，所述环形凸缘的外径与所述外套管的外径相同。穿刺套管上的环形凸缘和外套管的端面可形成用于夹持胆囊壁的夹持部件。当采用本发明所 提供的穿刺套管进行保胆手术时，当穿刺套管通过皮肤穿刺到胆囊中后，可利用该夹持结构夹紧胆囊壁，然后将芯针抽出，便可通过内套管中的通道进行取石(或息肉摘除)或其它辅助的手术操作。利用夹持结构夹紧胆囊壁的另一个有益技术效果是，可以从外部操作穿刺套管变换穿刺套管和胆囊壁之间的角度，方便观察，并且不会因为穿刺套管过深地插入胆囊而形成手术盲区。 The puncture sleeve provided by the present invention includes a clamping part for clamping the gallbladder wall. For example, the puncture sleeve can include a core needle, an inner sleeve, and an outer sleeve that are sequentially socketed. An annular flange is arranged on the outer peripheral surface of the inner sleeve, and the outer diameter of the annular flange is the same as that of the outer sleeve. The outer diameters of the tubes are the same. The annular flange on the puncture sleeve and the end surface of the outer sleeve can form a clamping part for clamping the gallbladder wall. When the puncture sleeve provided by the present invention is used for gallbladder preservation surgery, after the puncture sleeve is punctured into the gallbladder through the skin, the clamping structure can be used to clamp the gallbladder wall, and then the core needle can be pulled out to pass through the inner sleeve. The channel in the tube is used for stone removal (or polyp removal) or other auxiliary surgical procedures. Another beneficial technical effect of using the clamping structure to clamp the gallbladder wall is that the puncture cannula can be operated from the outside to change the angle between the puncture cannula and the gallbladder wall, which is convenient for observation and does not cause the puncture cannula to be inserted too deeply into the gallbladder And form the operation blind spot. the
为了使环形凸缘和外套管形成的夹持结构能将胆囊壁夹持得更加牢固，优选地，所述环形凸缘的与所述外套管的端面相接触的环面和所述外套管的与所述环形凸缘相接触的端面被设置为可紧密贴合。更优选地，所述环形凸缘的与所述外套管的端面相接触的环面和所述外套管的与所述环形凸缘相接触的端面为光滑平面。最优选地，所述环形凸缘的与所述外套管的端面相接触的环面和所述外套管的与所述环形凸缘相接触的端面为可紧密贴合的锯齿面。 In order to enable the clamping structure formed by the annular flange and the outer sleeve to clamp the gallbladder wall more firmly, preferably, the ring surface of the annular flange in contact with the end surface of the outer sleeve and the outer sleeve The end surface in contact with the annular flange is configured to be tightly fitted. More preferably, the ring surface of the annular flange in contact with the end surface of the outer sleeve and the end surface of the outer sleeve in contact with the annular flange are smooth planes. Most preferably, the annular surface of the annular flange in contact with the end surface of the outer sleeve and the end surface of the outer sleeve in contact with the annular flange are serrated surfaces that can be closely fitted. the
为了可以通过一定的外力，而不用手动操作来保持夹持结构的夹紧，优选地，所述穿刺套管还包括压簧，所述压簧套接在所述内套管外。这样，压簧可提供适当的夹紧力。所述穿刺套管可以被配置成在所述压簧的作用下，所述环形凸缘和所述外套管紧密贴合。 In order to keep the clamping structure clamped by a certain external force without manual operation, preferably, the puncture sleeve further includes a compression spring, and the compression spring is sleeved on the outside of the inner sleeve. In this way, the compression spring provides the proper clamping force. The puncture cannula can be configured such that under the action of the compression spring, the annular flange and the outer cannula are in close contact. the
另外，本发明所提供的穿刺套管的内套管与环形凸缘可以为一体成型，也就是，将内套管与环形凸缘加工成一体，也可以将内套管与环形凸缘分开加工，加工后组装成形。 In addition, the inner sleeve and the annular flange of the puncture sleeve provided by the present invention can be integrally formed, that is, the inner sleeve and the annular flange can be processed as one, or the inner sleeve and the annular flange can be processed separately. , assembled into shape after processing. the
本发明所提供的穿刺套管的内套管、外套管、芯针可以根据需要为塑料材质，也可为不锈钢材质或其它材质。 The inner cannula, outer cannula and core needle of the puncture cannula provided by the present invention can be made of plastic, stainless steel or other materials as required. the
利用本发明所提供的穿刺套管进行保胆手术的有益技术效果是：减少手术操作程序，缩短手术操作时间，使取石或息肉摘除更加方便，并可避免因为穿刺套管过深地插入胆囊而形成手术盲区。 The beneficial technical effects of using the puncture sleeve provided by the present invention for gallbladder-preserving surgery are: reducing the operation procedure, shortening the operation time, making it more convenient to remove stones or polyps, and avoiding gall bladder failure due to too deep insertion of the puncture sleeve into the gallbladder. Form a surgical blind spot. the
