Description
【技术领域】【Technical field】
本实用新型属于医疗器械领域，具体涉及一种血管识别腹腔镜。The utility model belongs to the field of medical instruments, in particular to a laparoscope for identifying blood vessels.
【背景技术】【Background technique】
在各种人体腔体内部进行检查、诊断、手术时，血管都是非常敏感的部位，明确血管的位置和走形，对医生非常有帮助。尤其是在做手术的时候，如果对血管的位置判断失误，损伤了血管，往往会导致严重的伤害。在外科手术尤其是微创手术日益发展的今天，腹腔镜手术携带其无可比拟的优势占据了主流位置。对于肿瘤切除要求的“骨骼化”，部分手术血管的“保护化”，无疑要求我们去寻找一种能够充分显示血管的一种设备。基于此，我们根据既往的研究情况，自助研发一种基于红外的内窥镜操作平台，其目的能够与常见的内窥镜进行分光显影的目的，做到对血管识别，易于医生应用的目的。本发明采用主动发射冷红外光线，根据血红蛋白与其他组织对红外光线的吸收比率不同，进而识别血管的位置与形态，辅助手术和诊断。能够极大提升手术成功率，降低患者术中出现血管损伤的风险，同时能够辅助医生进行诊断。本项目从最初的构思到目前的逐步形成一个思路以来，与多家企业进行了相关的沟通与交流。目前，项目集成了光学、设备基础、自动化、图像处理、医学基础操作等多方面人才对项目进行分析整合，力图在各方面的资助下能够完成该类设备的研发。在高清(1080P/4K)腹腔镜的技术上，加上红外识别的功能。高清是主体，红外是卖点。换句话说，没有血管识别需求的医生，也可以将本产品作为高清腹腔镜采购。Blood vessels are very sensitive parts when performing inspections, diagnoses, and operations inside various human cavities. It is very helpful for doctors to clarify the location and shape of blood vessels. Especially during surgery, if the position of the blood vessel is misjudged and the blood vessel is damaged, it will often lead to serious injury. With the increasing development of surgery, especially minimally invasive surgery, laparoscopic surgery has occupied the mainstream position with its incomparable advantages. For the "skeletalization" required for tumor resection and the "protection" of some surgical blood vessels, it is undoubtedly necessary for us to find a device that can fully display blood vessels. Based on this, we developed an infrared-based endoscope operating platform based on previous research. Its purpose is to perform spectroscopic imaging with common endoscopes, to identify blood vessels, and to be easy for doctors to use. The invention adopts the active emission of cold infrared light, according to the difference in the absorption ratio of hemoglobin and other tissues to the infrared light, and then recognizes the position and shape of the blood vessel, and assists the operation and diagnosis. It can greatly improve the success rate of surgery, reduce the risk of vascular injury in patients during surgery, and at the same time assist doctors in diagnosis. From the initial idea to the current idea of this project, we have communicated with many companies. At present, the project integrates optics, equipment foundation, automation, image processing, medical basic operation and other talents to analyze and integrate the project, and strives to complete the research and development of this type of equipment with the support of various parties. In addition to the technology of high-definition (1080P/4K) laparoscopy, the function of infrared recognition is added. HD is the main body, and infrared is the selling point. In other words, doctors who do not need blood vessel recognition can also purchase this product as a high-definition laparoscope.
