Embodiment Construction

[0011] Such as figure 1 A split-type multifunctional divider is shown, which includes a split-type surgical tool 1, and electrosurgical electrocoagulation blades 12 are arranged on both sides 11 of the head of the split-type surgical tool.

[0012] The split-off surgical knife is an ultrasonic knife or a force knife.

[0013] The present invention can be used for the separation of the liver and spleen parenchyma under laparotomy or laparoscopy. When the knife head clamps the tissue, the ultrasonic knife or the force knife and the electric knife work at the same time until the tissue is severed. While separating the tissue, it can achieve complete hemostasis on the parenchymal section of the liver and spleen through electrocautery electrocoagulation, which reduces intraoperative bleeding and shortens the operation time.

Abstract

The invention discloses a split type multifunctional divider which is characterized by comprising a split type surgical cutter. Electrotome electro-coagulation blades are arranged on two side faces of a head of the split type surgical cutter. The split type multifunctional divider is further characterized in that the split type surgical cutter is an ultrasound cutter or a force-confirming cutter. The split type multifunctional divider is not only a simple combination of the ultrasound cutter or the force-confirming cutter and an electrotome, but also an innovation on bleeding stopping schemes. The split type multifunctional divider has the same advantage of directly separating a ductule structure as the ultrasound cutter or the force-confirming cutter, stops bleeding of liver essence sections thoroughly through electrotome electro-coagulation, reduces bleeding in surgery, and shortens surgery operation time. Simultaneously, manufacture technology is mature, less cost is increased, and comprehensive benefits are evident compared with benefits brought for patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a split-type multifunctional divider, which is used for separating hemostasis from substantial organs or tissues such as liver and spleen. Background technique [0002] Existing liver parenchymal isolation tools are mainly used: vascular forceps, electric knife, ultrasonic knife, argon knife, water knife and so on. At present, the ultrasonic scalpel or Ligasure, which is commonly used in clinical operations on liver, spleen and other solid organs, has the advantage over other organ cutting instruments that it can directly cut off small-caliber blood vessels, especially in liver operations. However, after the liver parenchyma leaves the knife surface, its bleeding is still seen from time to time. The reason is that during the separation of the liver parenchyma, the hemostasis of the liver parenchyma is interrupted after separation, resulting in incomplete hemo...
