A puncture device for general surgery with local anesthesia

Abstract

A puncture device for general surgery with local anesthesia. The invention relates to the technical field of medical devices. The first connecting arm and the second connecting arm are respectively fixed on the side walls of the two ends of the elastic hoop; the elastic hoop close to the No. 1 connecting arm There is a through groove on the side wall, and the end of the No. 2 connecting arm is movable through the inside of the through groove; there is a connecting rod between the No. 1 connecting arm and the No. 2 connecting arm, and the two ends of the connecting rod are respectively connected to the No. 1 The arm is hinged with the No. 2 connecting arm; there is a chute on the side wall of the elastic hoop close to the No. The structure of the chute is matched with the setting; after the outer end of the slider moves through the chute, it is fixedly connected with the end of the No. At the same time, the acupuncture method can perform local anesthesia on the patient's thigh root, which reduces the patient's pain.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a puncture device for general surgery with local anesthesia. Background technique [0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for laboratory tests, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity. The purpose of puncture is blood test, infusion and catheter placement Do angiography, etc. When performing vascular puncture, the common ones are femoral artery puncture, femoral vein puncture, and subclavian vein puncture. The three blood vessels can be punctured to draw blood, and femoral artery can be inserted into a catheter for cardiac and cerebral angiography; In the prior art, when the femoral vein is punctured to draw blood, the femoral vein is generally disinfected and the hands of the medical sta...

Problems solved by technology

[0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for laboratory tests, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity. The purpose of puncture is blood test, infusion and catheter placement Do angiography, etc. When performing vascular puncture, the common ones are femoral artery puncture, femoral vein puncture, and subclavian vein puncture. The three blood vessels can be punctured to draw blood, and femoral artery can be inserted into a catheter for cardiac and cerebral angiography; In the prior art, when the femoral vein is punctured to draw blood, the femoral vein is generally disinfected and the hands of the medical staff are disinfected, and then the puncture needle is directly punctured manually to draw blood. When holding the puncture needle, due to tension or hands The trembling of the head can easily lead to inaccurate alignment. At the same time, when the puncture pain of the patient's femoral artery is strong, the leg is likely to move, causing secondary damage to the patient. Therefore, there is an urgent need for a general surgery with local anesthesia. piercing device
