Description

percutaneous tracheostomy anterior tracheal stoma

technical field

The utility model relates to a percutaneous tracheotomy device for the anterior wall of the trachea, which belongs to the field of medical supplies.

Background technique

The purpose of tracheotomy is to:

1. Relieve the obstruction of lower respiratory tract secretions caused by various reasons.

2. Relieve laryngeal obstruction caused by various reasons and improve breathing.

3. Respiratory weakness or respiratory arrest caused by various reasons requires artificial mechanical respiration.

In certain head and neck operations, tracheotomy is required because oral intubation affects the operation. Clinically, tracheotomy often requires emergency treatment, and patients who need tracheotomy or tracheal intubation are not treated in time, which directly leads to the death of the patient. There are two types of tracheotomy: direct surgical incision and percutaneous tracheotomy. Various reports at home and abroad have the advantages of minimally invasive, less complication, and simple operation. At present, a variety of percutaneous tracheotomy techniques It has been widely used in clinic.

The purpose of this utility model is achieved in that:

A percutaneous tracheotomy trachea anterior wall stoma device, the material of the percutaneous tracheotomy trachea anterior wall stoma device is stainless steel, it includes a tube body, a sleeve and a handle, the lower end of the tube body is from front to back A crescent-shaped sharp angle is formed after a 65-degree chamfer. The outer wall of the upper end of the pipe body is provided with external threads, and the inner wall of the sleeve is provided with internal threads. The thread fits so that the sleeve is placed on the upper end of the pipe body. The inner hole of the pipe body is larger at the top and smaller at the bottom. At the corresponding position at the lower end of the sleeve, the diameter of the inner hole of the pipe body transitions from a large diameter to a small diameter. The handle includes There are two left and right handle rods, and the left and right sides of the sleeve are respectively connected with horizontal handle rods outward.

An anti-skid ring is arranged on the handle bar, and the anti-skid ring extends from one end of the handle bar to the other end.

The sleeve is sequentially provided with an upper circle section, an upper cone section, a middle circle section, a lower cone section and a lower circle section from top to bottom, and an upper circle section, an upper cone section, a middle circle section, a lower cone section and a lower circle section The transitions between are smooth transitions.

The outer wall of the middle circular section is provided with sleeve anti-slip lines arranged vertically and evenly.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model percutaneous tracheotomy trachea front wall stoma device includes a tube body, a sleeve and a handle, and has a simple structure and low cost. In addition, the utility model percutaneous tracheotomy trachea front wall stoma device is made of stainless steel and has relatively high strength. High, sterilized and reusable. Therefore, the utility model has the advantages of simple structure, low cost, convenient use and reusability.

detailed description

Referring to Fig. 1 , a percutaneous tracheotomy tracheal stoma stoma device related to the utility model is made of stainless steel, and it includes a tube body 1, a sleeve 2 and Handle 3, the lower end of the tube body 1 is beveled at 65 degrees from front to back to form a crescent-shaped sharp angle 1.1, the outer wall of the upper end of the tube body 1 is provided with external threads, and the inner wall of the sleeve 2 is provided with internal threads , the internal thread of the sleeve 2 cooperates with the external thread of the upper end wall of the pipe body 1, so that the sleeve 2 is placed on the upper end of the pipe body 1, the inner hole of the pipe body 1 is larger and the lower is smaller, and the sleeve The diameter of the inner hole of the pipe body 1 at the corresponding position of the lower end transitions from a large diameter to a small diameter. The sleeve 2 is provided with an upper circle section 2.1, an upper cone section 2.2, a middle circle section 2.3, a lower cone section 2.4 and a lower circle section 2.5 from top to bottom, an upper circle section 2.1, an upper cone section 2.2, and a middle circle section 2.3. The transition between the lower cone section 2.4 and the lower circular section 2.5 is a smooth transition. The outer wall of the middle circular section 2.3 is provided with sleeve anti-skid lines evenly arranged vertically. The handle 3 includes two left and right handle rods. The left and right sides of the middle circle section 2.3 of the sleeve 2 are respectively connected with horizontal handle rods outwardly. The handle rod is provided with an anti-slip ring extending from one end of the handle rod to the other end.

When making the anterior tracheal wall, two types of percutaneous tracheostomy anterior tracheostomy devices are required, namely, the first-level percutaneous tracheostomy anterior tracheostomy device and the second-level percutaneous tracheostomy Anterior tracheal stoma.

Among them, the first-level percutaneous tracheotomy device has an outer diameter of 3±0.02mm, a length of 48±0.5mm, and a wall thickness of 0.2mm. The distance between them is 5mm, and the outer diameter of the handle rod is 2mm.

Among them, the external diameter of the tube of the secondary percutaneous tracheotomy tracheal stoma is 4.5±0.02mm, the length of the tube is 54±0.6mm, and the wall thickness of the tube is 0.2mm. The distance between them is 5mm, and the outer diameter of the handle rod is 2mm.

When in use, routinely sterilize the neck in the ward or the operating room, keep the trachea in the midsagittal position, and cut the skin 1.5cm-2cm horizontally at the two transverse fingers under the cricoid cartilage on the anterior midline of the neck, separate the subcutaneous tissue, and feel it with your fingers In the tracheal ring space, use a deep vein puncture needle to connect a syringe (containing 2% lidocaine 2-3ml), puncture it vertically into the trachea, and when there are air bubbles in the syringe, confirm that the puncture needle enters the trachea, inject lidocaine injection 2-3ml, pull out the syringe, and feed the guide wire along the inner cavity of the puncture needle. When the guide wire enters the trachea and cough reflex occurs, withdraw the puncture needle, and send the first-level percutaneous tracheostomy device along the guide wire to the anterior wall of the trachea. , while withdrawing the guide wire, twist the first-level percutaneous tracheotomy anterior tracheal stoma to construct the anterior tracheal wall, re-introduce the guide wire after feeling a breakthrough, and exit the first-level percutaneous tracheotomy anterior tracheal wall at the same time The ostomy device is then sent into the secondary percutaneous tracheotomy trachea anterior wall stoma along the guide wire to expand the fistula on the anterior trachea wall, and the special tracheal dilation forceps are inserted along the guide wire so that the curved part of the tracheal dilation forceps faces the distal end. Open the tracheal dilating forceps to further expand the tracheal fistula. When tracheal secretions or gas can be seen overflowing from the fistula, withdraw the tracheal dilating forceps and introduce a disposable tracheal cannula along the guide wire.
