A polymer vascular clip automatic burst device

technical field

The invention relates to the technical field of medical aids, in particular to an automatic bursting device for polymer blood vessel clips.

Background technique

Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used in the human body, including required computer software, and medical devices include medical equipment and medical consumables. The utility is mainly obtained by physical means, not by pharmacological, immunological or metabolic means, or although these means are involved but only play an auxiliary role. The purpose is diagnosis, prevention, monitoring, treatment or alleviation of disease; diagnosis, monitoring, treatment, alleviation or functional compensation of injury; inspection, replacement, adjustment or support of physiological structure or physiological process; life support or maintenance; pregnancy control; By examining samples from the human body to provide information for medical or diagnostic purposes, with the development of the medical industry, minimally invasive surgical instruments have become more and more widely used in clinical practice. In minimally invasive surgery, vascular clips can play a role in hemostasis or control the direction of blood vessel blood flow, thereby ensuring the smooth completion of the operation. However, the vascular clip will cause certain damage to the blood vessel during use. If the overall structural design of the vascular clip is unreasonable, it is easy to cause excessive clamping force during the process of clamping the blood vessel, thereby causing problems such as vascular adventitia damage and cross infection. Therefore, the research on vascular trauma caused by vascular clips is also deepening. Scholars at home and abroad have carried out many studies based on biomaterials, biomechanics and histology, using different contact and damage models to evaluate the safety and effectiveness of the device. Gasser et al. established a three-dimensional finite element model of aortic vascular clips under the condition of considering residual stress. The results showed that there is a tensile stress peak area in the clamping area of the vascular clip, which will lead to the damage of the vascular intima to a certain extent. Vascular clips are used to stop bleeding from blood vessels.

Commonly used vascular clips cannot efficiently and continuously ligate blood vessels during surgery, and at the same time, vascular clips do not have biocompatibility, the safety factor of vascular clips is relatively low, and there are disadvantages of tissue cutting. Therefore, it is necessary to invent an automatic bursting device for polymer blood vessel clips with automatic bursting, high efficiency and self-absorption.
