Visual hydrothorax and ascites injection and suction device and auxiliary device thereof

Abstract

The invention relates to a visual hydrothorax and ascites injection and suction device and an auxiliary device thereof. The auxiliary device comprises that a flexible endoscope embedded with an optical fiber lighting unit is arranged inside a puncture trocar for long-distance observation and real-time shooting, so that medical care personnel can in real time observe puncture position and conditions as well as surgical operation position and conditions; a needle tip is provided with a certain inclined surface to avoid secondary injury to punctured positions due to inclination or movement of a sharp puncture needle; under guidance of real-time images, complications caused by conventional blind puncture can be avoided; meanwhile, ultra-micro optical fiber imaging can avoid radiation influenceand acoustic channel limitation and be applicable to bedside operation, thereby providing a safe and reliable technical means for manual hydrothorax and ascites injection and suction. The visual hydrothorax and ascites injection and suction device is simple in structure, reasonable in design, accurate in puncture positioning, capable of saving operation time and reducing injury of patients as well as operation risks, high in practicality and reliability and easy to generalize and apply.

Description

technical field [0001] The present invention relates to a novel medical device, more specifically, to a visualized pleural fluid injection and suction device and its auxiliary device. Background technique [0002] "Haifudao" is the translated name of "High-intensity focused ultrasound (HIFU)". Haifu knife technology is to use the good penetrability, directionality and focusability of ultrasound in the tissue to focus the low-intensity ultrasound outside the body when passing through the tissue, and place the high-energy ultrasound beam in the focal region in the target area , to generate instantaneous high temperature (60-100°C), causing coagulation necrosis of the tissue in the focal area, and almost no damage to the tissue outside the focal area, thus accurately killing the tissue in the target area. The physical characteristics of ultrasound determine that it cannot penetrate the gas-containing viscera, thus affecting the extracorporeal treatment of Haifu Knife on the to...

Problems solved by technology

[0006] (2) Moreover, due to individual reasons of some patients, puncture positioning is difficult, and many inexperienced doctors have repeatedly punctured, which wastes time and increases the injury of patients; even some operators fail to enter the pleural cavity and peritoneal cavity with the puncture needle , just inject sterile saline, which directly leads to complications such as subcutaneous edema and subcutaneous emphysema in patients; since Haifu knife needs to be punctured again to extract artificial pleural and ascites, adding an invasive operation, currently clinically generally do not use artificial The pleural and ascites are pumped out to allow patients to absorb themselves after surgery, which increases the risk of perioperative surgery and hospitalization time for patients

However, the existing technologies have their own shortcomings, among which X-ray and CT-guided technologies not only have the potential risk of X-ray radiation, but also have high costs and increase the burden on patients

Ultrasound-guided visual puncture is the ideal method currently recommended in clinical practice. However, for thoracic deformity, the ultrasound probe cannot fit closely with the skin, rib acoustic shadow interference caused by narrowed intercostal space, chronic obstructive pulmonary disease and obesity, etc. lead to acoustic window conditions. In limited circumstances, the effect of ultrasound guidance cannot be effectively guaranteed, thus limiting the further promotion of ultrasound guidance strategies
