A simple percutaneous lung puncture and puncture complications management tool

Abstract

The invention discloses a simple percutaneous lung puncture and puncture complication treating tool. The tool comprises a positioning needle and a switching mechanism, wherein the positioning needle comprises a needle head and a soft tube, the needle head is connected to one end of the soft tube, the soft tube is sleeved by a coaxial puncture needle sleeve, and a biopsy needle insertion hole, a medicament feeding hole capable of being communicated with the soft tube, and an air flow guide tube are arranged on the switching mechanism. The tool has the various functions including anesthetization, puncture sampling, complication treatment and the like, the functions can be flexibly switched according to the demands, the complications occurring after puncture can be conveniently coped with in time, with the adoption of the tool provided by the invention, the percutaneous lung puncture and complication treating operation efficiencies can be improved, and the additional injury caused to patients during the percutaneous lung puncture and the complication treating operation can be alleviated.

Description

technical field [0001] The invention relates to a medical device, more specifically, it relates to a simple percutaneous lung puncture and a tool for treating complications of the puncture. Background technique [0002] Percutaneous lung puncture is currently a commonly used diagnostic method for lung diseases. At present, the commonly used instruments for percutaneous lung puncture in my country include syringes for injecting anesthetics, biopsy needles for lung biopsy sampling, and biopsy needles for positioning. The general operation steps for puncture operation using the above instruments are as follows: 1. First determine the site to be punctured with the assistance of CT or ultrasound positioning; 2. Inject anesthesia with a syringe according to the positioning, and perform local infiltration anesthesia layer by layer. Pull out the syringe after anesthesia; 3. Use the needle eye on the skin to determine the anesthesia site, and puncture the coaxial puncture needle into t...

Problems solved by technology

Due to the influence of respiratory activity on the above operations, the coaxial puncture needle cannot ensure smooth and accurate puncture in place at one time, and multiple punctures are often required with the help of CT or ultrasound positioning

Due to the limitations of the equipment, the above-mentioned percutaneous lung puncture method has the following disadvantages: in the process of local anesthesia, the coaxial puncture needle needs to be positioned through images to confirm that the coaxial puncture needle can reach the target site through the local anesthesia site, so that The patient may receive CT rays or ultrasound multiple times, causing physical damage; affected by respiratory movement, the puncture target part moves, and the coaxial puncture needle is difficult to puncture successfully at one time, and may need to be repeated many times, which increases the pain of the patient; repeated puncture and multiple The secondary image positioning will cause a serious waste of time and further increase the load on the already very busy medical unit; the puncture operation can easily cause pneumothorax or hemopneumothorax, and once it occurs, it is difficult to deal with it quickly due to the limitations of tools, and only partial re-treatment is required. For anesthesia, additional puncture is performed with the help of image positioning to perform thoracic exhaust. During this period, not only more drugs and equipment are consumed, but also more treatment time is spent, and there is a high possibility of serious consequences due to untimely treatment.

However, when this invention is used, it is mainly guided by image positioning. Due to the influence of respiratory movement, it is still difficult to quickly and accurately puncture the target part of the lung.
