Description

A minimally invasive thoracic closed drainage and puncture operation kit

technical field

The utility model relates to the technical field of medical devices, in particular to a minimally invasive chest cavity closed drainage and puncture operation kit.

Background technique

Closed thoracic drainage is an operation performed in the treatment of patients with pneumothorax, pleural effusion and other diseases, which is conducive to the drainage of gas and/or fluid and improves the symptoms of patients. The current method of closed thoracic drainage is to select the puncture site, infiltrate the anesthesia and cut the skin about 1 cm with a blade, then bluntly dissect the subcutaneous tissue, muscle and parietal pleura into the thoracic cavity, and then insert the thoracentesis needle into the thoracic cavity , The drainage tube used is a soft plastic tube, and the end is connected to a closed drainage bottle. This operation method needs to be completed by a thoracic surgeon, and there is more bleeding during blunt dissection, especially in critically ill patients and patients with poor coagulation function. Postoperative bleeding complications are more common and often affect patient outcomes. In the prior art, there is no molded thoracic cavity closed drainage puncture kit, and the thoracentesis needles are divided into different diameter models. Clinicians need to select thoracocentesis needles with different diameters according to clinical needs. Since the thoracic cavity closed drainage tube is a plastic hose, The chest wall muscles on the operation path are thick and have a certain degree of flexibility. Although blunt dissection has been performed in the early stage, in order to ensure that it can enter the chest cavity smoothly, a long and straight metal tube must be inserted into the drainage tube first, so as to facilitate the operation. The drainage tube can withstand a certain pressure during the process of being placed in the chest cavity, keep the drainage tube from deformation, ensure that the tube core is pulled out after entering the chest cavity, and the position is fixed. Due to the different positions of the lesions in different patients, when the drainage tube enters the thoracic cavity, it is necessary to adjust the direction and angle according to the position of the lesion to reach the ideal position of the pleural effusion in order to produce the best drainage effect. The existing tube core is made of hard metal material, which cannot generate a radian, and the puncture angle is often inaccurate, which affects the drainage effect. This operation method needs to be completed by a thoracic surgeon and requires the operator to have certain skills, and the blunt dissection operation has more bleeding, especially in critically ill patients and patients with poor coagulation function. Postoperative bleeding complications are more common, and also often affects patient outcomes.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The cone-tip dilator 8 of the present invention is used to expand the skin and subcutaneous tissue for the first time, and the cone-tip thread dilator 9 is used to expand the skin, subcutaneous tissue and chest wall muscles for the second time, which can reduce bleeding during the operation and save more effort. . The cone-tip thread dilator is divided into 9 sizes and models with different diameters, and is suitable for different types of thoracic drainage tubes. During the process of rotating the tapered-tip thread expander 9 into the skin, the subcutaneous tissue and muscle will be lifted up along with the thread, and the skin and muscle will not be squeezed, thereby reducing damage. Because the surgical sinus has been opened after two dilations, a rigid metal tube is no longer required, and costs can also be reduced. The tube core 11 made of flexible plastic material with a certain curvature can adjust the needle insertion angle according to the lesion site, which can be positioned more accurately and has better drainage effect.

As shown in Figures 1 to 11, the present invention provides a minimally invasive thoracic cavity closed drainage and puncture operation kit, and the operation steps are as follows:

1. Determine the puncture point by positioning. After local infiltration anesthesia, use the puncture needle 3 to puncture the skin vertically, and then withdraw gas or pleural effusion after feeling a breakthrough. (see Figure 6)

Second, after the guide wire 6 is inserted into the puncture needle 3, the puncture needle 3 is pulled out. (see Figure 7)

Third, use a scalpel 7 to make an incision of about 1 cm parallel to the intercostal space to reach the dermis. (see Figure 8)

Fourth, along the guide wire 6, place a conical tip dilator 8 to the subcutaneous tissue and muscle layer. (see Figure 9)

Fifth, after pulling out the cone-tip dilator 8, put the cone-tip thread dilator 9 along the guide wire 6, and rotate it clockwise to enter the thoracic cavity. (see Figure 10)

6. Rotate counterclockwise to exit the conical-tip thread dilator 9, place the tube core 11 into the chest cavity drainage tube 10, and insert it into the chest cavity along the guide wire 6 perpendicular to the chest wall 2, adjust the chest cavity drainage tube 10 radians in the desired direction and push it in The thoracic cavity, pull out the stylet 11 and the guide wire 6, and connect the closed drainage bottle at the end of the thoracic cavity drainage tube 10. (see Figure 11)
