本发明涉及微创手术设备,特别涉及一种肝脏穿刺器。The present invention relates to minimally invasive surgical equipment, in particular to a liver puncture device.
肝脏是血流量极其丰富的实质性脏器,其总血流量可占心排血量的1/4。肝切除术,即切除部分肝脏实质的技术,此过程中最为关键的难题是控制出血,一旦出现出血等问题可能导致患者死亡,后果极其严重。因此肝血流阻断控制技术成为肝切除技术的重要辅助手段。1908年Pringle首次发明第一肝门阻断技术,开创了肝外血流阻断的先河:该技术在肝外结扎肝十二指肠韧带,整体上阻断所有入肝的血流管道实现控制出血。此后,研究者在此基础上发展了各类阻断技术,推动了肝脏外科的飞速发展。它们虽然简单有效,但由于都是不加区分的肝外整体阻断,导致阻断若过度或时间过长则易引起全肝的缺血再灌注损伤、术后肝功能衰竭死亡等严重并发症。因此,如何恰当有效而又保证损伤程度最低地进行肝血流阻断一直是医学界探讨和研究的一个重要问题。The liver is a solid organ with extremely rich blood flow, and its total blood flow can account for 1/4 of cardiac output. Hepatectomy is a technique to remove part of the liver parenchyma. The most critical problem in this process is to control bleeding. Once bleeding and other problems occur, the patient may die, with extremely serious consequences. Therefore, hepatic blood flow occlusion control technology has become an important auxiliary method for liver resection technology. In 1908, Pringle first invented the first porta hepatis occlusion technology, pioneering the occlusion of extrahepatic blood flow: this technology ligated the hepatoduodenal ligament outside the liver, blocking all blood flow channels into the liver as a whole to achieve control. Bleeding. Since then, researchers have developed various blocking technologies on this basis, promoting the rapid development of liver surgery. Although they are simple and effective, because they are all indiscriminate extrahepatic blockade, if the blockade is excessive or for too long, it can easily cause serious complications such as ischemia-reperfusion injury of the whole liver, postoperative liver failure and death. . Therefore, how to block hepatic blood flow appropriately and effectively while ensuring the lowest degree of damage has always been an important issue discussed and researched by the medical community.
另一方面,新近发展起来的解剖性肝切除技术是根据肝脏内的血管逐级分支、区段性供应的特点,切除某一级主干血管所支配的肝组织,这种根据肝内血管解剖分布特点的切除方式由于可以把肿瘤、结石等病灶区段完整的去除而受到推崇。这种技术对肝血流阻断的要求 更高,而且需要对肝内血管的走形分布有透视般的清晰了解。但是肝脏组织是充满红色血液、不透明的实质器官,术者无法透视血管的位置,仅能凭借术前检查进行经验推测,或者术中超声、CT等方案来实时检测。前者依据主观判断显然不够精准,后者操作复杂、配套设备昂贵,而且存在精度较低或者受到脏器运动实时位置改变的影响,难以精细分辨、并普及实施。On the other hand, the newly developed anatomical liver resection technology is based on the characteristics of the gradual branching and segmental supply of blood vessels in the liver to remove the liver tissue dominated by a certain level of main blood vessels. This method is based on the anatomical distribution of intrahepatic blood vessels. This unique resection method is highly praised because it can completely remove lesions such as tumors and stones. This technique has higher requirements for hepatic blood flow occlusion, and requires a clear and fluoroscopy-like understanding of the distribution of intrahepatic blood vessels. However, the liver tissue is an opaque solid organ filled with red blood. The operator cannot see through the location of the blood vessels. He can only make empirical inferences based on preoperative examinations, or perform real-time detection through intraoperative ultrasound, CT and other solutions. The former is obviously not accurate enough based on subjective judgment, while the latter is complicated to operate, has expensive supporting equipment, and has low accuracy or is affected by real-time position changes of organ movement, making it difficult to distinguish finely and implement it universally.
我们创造性的提出直接穿刺进入器官内进行止血理论和手术野三维地形图理论,将血流控制由肉眼可见的实质脏器外总血管精准到实质内的分支血管,并且将被切除的器官组织的实时解剖位置实现坐标化,从而为将来的全自动手术切除奠定了基础。相应的,我们研发了一套全新的肝内血流阻断理论、以及实时精准判断肝内血管等组织结构位置的装置,使得术者可以最精准的控制病变肝段的血流,并实时精准快速的定位实质脏器内的解剖结构,可以辅助高质快速的完成包括解剖性肝切除的止血在内的各类手术。We creatively put forward the theory of direct puncture into the organ for hemostasis and the theory of three-dimensional topography of the surgical field, which accurately controls the blood flow from the main blood vessels outside the parenchyma visible to the naked eye to the branch blood vessels in the parenchyma, and also controls the blood flow of the resected organs and tissues. The real-time anatomical position is coordinated, thus laying the foundation for future fully automated surgical resection. Accordingly, we have developed a new theory of intrahepatic blood flow occlusion and a device that accurately determines the location of intrahepatic blood vessels and other tissue structures in real time, allowing the operator to most accurately control the blood flow of the diseased liver segment and perform real-time and accurate treatment. Rapidly locating anatomical structures within parenchymal organs can assist in the high-quality and rapid completion of various surgeries including hemostasis of anatomical liver resection.

The core rod 2 can be inserted into the sleeve 1. Specifically, the sleeve 1 is tubular. , one end of the sleeve 1 is provided with a V-shaped snap-in nozzle 11, the V-shaped snap-in nozzle 11 is provided on the side wall of the sleeve 1, and there are two V-shaped snap-in nozzles 11, two V-shaped snap-in connectors 11 are arranged opposite each other. The V-shaped snap-in nozzle 11 is used to clamp and fix blood vessels. A sleeve ring 12 is provided at the other end of the sleeve 1. The sleeve ring 12 is arranged on the end surface of the sleeve 1. The outer side of the sleeve 1 An air bag 13 is provided on the edge of the sleeve 1. The air bag 13 is arranged along the axial direction of the sleeve 1. An expansion sleeve 14 is provided on the outer edge of the air bag 13. When the air bag 13 is inflated, the air bag 13 pushes the expansion sleeve 14 away from the center of the sleeve 1. Movement plays a role in expanding the expansion sleeve 14, and the expanded expansion sleeve 14 squeezes the passing liver tissue wound to achieve the purpose of hemostasis.
胀套14包括多个收尾相连的膨胀单元,每个膨胀单元包括一个外壁141和一个连接件142,外壁141和连接件142均为弧形,多个外壁141呈环形布置,多个外壁141构成了一个虚拟的圆形,该圆形的圆心与套筒1的圆心重合,且虚拟的圆形与所述套筒1构成相似圆形。前述的连接件142设置在外壁141与套筒1之间且连接件142的弧度弯折方向与外壁141的弧度弯折方向相反,每个膨胀单元的连接件142一端与本膨胀单元的外壁141连接,另一端与另一膨胀单元的外壁141连接。The expansion sleeve 14 includes a plurality of expansion units connected at the end.

Act on connector 142. When the connecting piece 142 is deformed under force, the two ends of the connecting piece 142 push the outer wall 141 to move away from the center of the sleeve 1 under the action of elastic force, thereby realizing the expansion of the expansion sleeve 14 . During the process of establishing a channel in the liver, since the wound is not large, there is no need for the expansion sleeve 14 to expand to a large extent. Therefore, when the expansion sleeve 14 provided by the present application is used, the outer wall 141 is deformed to achieve the purpose of squeezing and hemostasis. In addition, due to the structural characteristics of the expansion unit, the plurality of outer walls 141 are arranged at intervals. Therefore, part of the liver tissue will also be squeezed by the connector 142 when the purpose of extrusion and hemostasis is achieved, which can effectively achieve hemostasis of the liver. Preferably, the edges of the connecting piece 142 and the outer wall 141 are rounded.
