Indwelling catheter for post-operation anesthesia

Abstract

The invention belongs to medical instruments for local anesthesia and discloses an indwelling catheter for post-operation anesthesia. The front end of the catheter is provided with a closed round head, and the catheter is provided with a plurality of side holes. When the indwelling catheter is used in a surgery process, the catheter is embedded in the orientation parallel to the spine to an extrapleural paravertebral space area on the surgery side or near an open surgery incision, the side holes are positioned at emission portions of nerves among multiple sterna ribs on the surgery side, surgery-side thoracic vertebrae 1-thoracic vertebrae 12, multi-segment and continuous paravertebral block anesthesia is realized, defects of single-segment paravertebral block anesthesia are overcome, and various adverse reactions caused by post-operation intravenous analgesia can be reduced or eliminated. The indwelling catheter for post-operation anesthesia has advantages that the problem of pains caused by operation holes and drainage tube holes after minimally invasive thoracoscopic surgeries is mainly solved, simplicity and safety in operation are achieved, anesthetics can be continuously and accurately pumped to paravertebral spaces, and great surgery-side thoracic wall analgesia and anesthesia effects, fast recovery of patients and high feasibility are realized.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical device for local anesthesia in thoracic surgery and its application method. Background technique [0002] No matter open surgery or minimally invasive surgery, there will be surgical incisions during the surgical operation. Postoperative pain is one of the important reasons that affect the patient's recovery and quality of life. [0003] my country is an area with a high incidence of esophageal cancer, and its incidence rate ranks first in the world. About 150,000 people die from esophageal cancer every year, accounting for nearly a quarter of all malignant tumor deaths. With the increase of air pollution, the incidence of lung cancer in my country is also increasing year by year, and it is currently the highest incidence of various cancers. The annual economic loss is as high as tens of billions, seriously affecting the national economy and people's livelihood. The treatment of eso...
