Puncture device with local anesthesia for general surgery

Abstract

The invention relates to the technical field of medical instruments, in particular to a puncture device with local anesthesia for general surgery, which is characterized in that a first connecting arm and a second connecting arm are fixedly arranged on the side walls of two ends of an elastic hoop respectively; a through groove is formed in the side wall, close to the first connecting arm, of the elastic hoop, and the end of the second connecting arm is movably arranged in the through groove in a penetrating mode. A connecting rod is arranged between the first connecting arm and the second connecting arm, and the two ends of the connecting rod are hinged to the first connecting arm and the second connecting arm respectively. A sliding groove is formed in the portion, close to the second connecting arm, of the side wall of the elastic hoop, the sliding groove is of an inverted-T-shaped structure, a sliding block is slidably embedded in the sliding groove, and the sliding block is matched with the sliding groove in structure; after the outer end of the sliding block movably penetrates through the sliding groove, the outer end of the sliding block is fixedly connected with the end of the first connecting arm, after the position of the femoral vein is accurately found, needle application can be stably carried out, an automatic needle application mode is adopted. Meanwhile, local anesthesia can be carried out on the thigh root of a patient, and pain of the patient is relieved.

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
