Disposable thoracic closed drainage tube indwelling guide kit

Abstract

The invention relates to a disposable thoracic closed drainage tube indwelling guide kit which comprises a guide rod for guiding a guide clamp and the guide clamp guiding a drainage tube to be indwelled.The guide rod is composed of a round rod and a platform, the guide clamp is formed by connecting a left handle with a right handle in a hinged manner through a connecting shaft, and an elastic piece is arranged between the lower portions of the left handle and the right handle.The disposable thoracic closed drainage tube indwelling guide kit is technically characterized in that the guide rod is the round rod which is marked with scales on the surface and is 0.4-0.5 cm in diameter and greater than 7.4 cm in length, length of a guide head is greater than 3.7 cm, and the guide head and a clamp body form an included angle of 135 degrees.The disposable thoracic closed drainage tube indwelling guide kit has the advantages of simple structure and convenience in operation and has popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a disposable thoracic closed drainage tube insertion guide set. Background technique [0002] For patients with pleural effusion, since the pleural effusion contains protein components, flocs are often produced in the effusion. In order to avoid blockage, thicker silicone drainage tubes are usually used to drain the effusion clinically. The specific operation steps are: after local anesthesia, use tissue forceps to open the pleura to establish an external channel, then use the forceps holding the drainage tube to send the drainage tube into the chest cavity along the channel, and finally withdraw the forceps clamping the drainage tube to fix the drainage tube. During the operation, the operator will face two difficulties: 1. If the tissue forceps withdraw from the chest immediately after the channel is established, the position of the channel will change due t...

AI Technical Summary

Problems solved by technology

During the operation, the operator will face two difficulties: 1. If the tissue forceps withdraw from the chest immediately after the channel is established, the position of the channel will change due to muscle elasticity, thoracic movement caused by the patient’s breathing, and body movement caused by pain. It is difficult to place the drainage tube; 2. If you do not withdraw the tissue forceps, but use the tissue forceps as the guiding forceps of the drainage tube, at this time, due to the narrow channel space and the opening of the tissue forceps in a triangular shape with a small outside and a large inside, the forceps clamping the drainage tube It will fight with tissue forceps, which will also cause difficulties in the placement of drainage tubes; 3. Young doctors have less experience

The prolongation of the operation time will undoubtedly increase the trauma of the patient, therefore, it is necessary to provide a guiding device for the drainage tube of chest cavity drainage with simple structure and convenient operation
