技术领域technical field
本发明属于医疗器械技术领域，具体涉及一种多功能肝胆外科用止血器。The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional hemostat for hepatobiliary surgery.
背景技术Background technique
在临床上在给病人进行肝胆外科手术时，用手术刀做切面后需要立即对伤口进行止血，目前常用的止血方法是电凝止血，电凝法有单极电凝和双极电凝之分，单极电凝的工作原理是利用单极电刀的高频电流通过电刀头、人体组织和患者极板构成一个完整的回路，电凝时使组织细胞迅速脱水、凝固、达到止血目的；双极电凝的工作原理是应用高频的大功率正弦波，通过双极电凝的两个尖端部分释放，从而在电凝之间的人体组织产生热效应，以凝固血液中的蛋白质，从而达到止血效果。但是不管是单极电凝还是双极电凝都存在如下的问题：1、手术中会产生大量烟雾，导致手术视野模糊，一方面延长了手术时间，另一方面，烟雾中含有有毒气体；2、电凝止血热效应大、热损较大。因此，本发明旨在提供一种无辐射、热损小、采用热凝的肝胆外科用止血器。Clinically, when performing hepatobiliary surgery on a patient, the wound needs to be hemostasis immediately after cutting the surface with a scalpel. At present, the commonly used method of hemostasis is electrocoagulation. Electrocoagulation can be divided into unipolar electrocoagulation and bipolar electrocoagulation. , the working principle of monopolar electrocoagulation is to use the high-frequency current of the monopolar electrosurgical unit to form a complete circuit through the electrosurgical head, human tissue and the patient's plate. During electrocoagulation, the tissue cells are rapidly dehydrated and coagulated to achieve hemostasis; The working principle of bipolar coagulation is to apply high-frequency high-power sine waves, which are released through the two tip parts of bipolar coagulation, so as to generate a thermal effect on the human tissue between the coagulation, so as to coagulate the protein in the blood, so as to achieve Hemostatic effect. However, no matter whether it is unipolar coagulation or bipolar coagulation, there are the following problems: 1. A large amount of smoke will be generated during the operation, resulting in blurred surgical vision. On the one hand, the operation time is prolonged, and on the other hand, the smoke contains toxic gases; 2. , Hemostatic thermal effect of electrocoagulation is large, and the heat loss is large. Therefore, the present invention aims to provide a hemostat for hepatobiliary surgery with no radiation, little heat loss and heat coagulation.
