Description

Thoracic closed drainage tube implantation expansion forceps

technical field

The utility model belongs to medical instruments and relates to an expansion forceps.

Background technique

Chest drainage surgery is one of the more common clinical operations. It is used to drain fluid or gas in the chest cavity, and the condition is often urgent. However, complications are often caused by the operation, including damage to the nerves and blood vessels of the chest wall, damage to the chest and abdominal organs, or the difficulty of the operation increases the patient's pain and delays the rescue time.

The traditional implantation method uses vascular forceps to bluntly separate the subcutaneous tissue and intercostal muscles, enters the thoracic cavity to create a tunnel, and then implants into the thoracic cavity with a vascular forceps clamped with a chest tube, or implants a chest tube with a needle into the thoracic cavity . Chest tubes with needles are often easier to insert, but because they have a sharp inner core, the implantation operation is more likely to damage important organs, especially if the force is not well controlled, it will suddenly enter the chest too deep, and it is easy to make the chest Injury to important internal or upper abdominal organs. Chest tubes without needles often have relatively high resistance during implantation, so if you do not separate the large chest wall incision, you need to use greater force to implant, which will inevitably increase the operation time and damage to the chest wall. Similarly, if the force Poor control also has the danger of causing internal organ damage.

In response to the above problems, many clinical improvements have been made at present, such as improving the design and material of the chest tube, reducing the size of the chest tube; there are tube-type implant devices with inner cores, which are inserted through the chest wall and then pulled out. Insert the chest tube into the inner core, and then pull out the instrument; there are tweezers that can be opened at the head end to assist the implantation of the chest tube, making the operation of surgical implantation easier and safer. But all there is certain deficiency aspect in these apparatuses. For example, the size of the tubular implant device with inner core is fixed, and after implantation, it must be withdrawn through the chest tube, which makes some chest tubes with connectors at the end unusable. The tip of the tweezers whose head can be opened is still relatively sharp, which is easy to damage important organs.

Utility model content

The purpose of the utility model is to provide a chest closed drainage tube implant expansion forceps, the head of which is blunt and expandable, safe to use and easy to operate.

For achieving above object, the solution of the present utility model is:

An expansion forceps, which includes an inner core, a handle and a tongue part with expansion function, when the tongue part is closed, its cross-section is oval, and the head is thinner and the end is thicker, and the end and the handle are connected at a certain angle, The inner core is used inside the tongue part.

The tip of the tongue portion is blunt and its lines are smoothly connected.

The length of the tongue part is 6-8cm; the major axis of the elliptical section at the head end is 0.5cm-1.2cm, and the minor axis is 0.3cm-0.6cm; the major axis of the terminal elliptical section is 0.8cm-1.5cm, and the minor axis is 0.5cm cm-1.0cm.

The tongue part and the handle are connected at 90-120 degrees, and the end of the tongue is integrally formed and connected with the handle.

The blunt head of the inner core is a smooth arc surface, and the size and shape match the space formed when the tongue is partially closed.

The end of the inner core is also provided with an enlarged part to prevent the inner core from slipping too deeply after implantation.

It also includes a small buckle that clasps the core inserted into the tongue portion, which fits at the end of the tongue.

Due to the adoption of the above technical scheme, the utility model has the following beneficial effects: the closed thoracic drainage tube implanted with expansion forceps can control the depth of instrument implantation in the chest tube implantation operation, the head end is round and blunt, and the inner diameter is small, After the chest wall is implanted, the incision is expanded by dilation, which makes the operation of chest tube implantation easier, shortens the operation time, reduces the occurrence of surgical complications, and is safer.

Detailed ways

Below in conjunction with the embodiment shown in the accompanying drawings the utility model is further described.

Expansion forceps used for implantation of closed thoracic drainage tubes, which consist of an expandable forceps head (as shown in Figure 1) and a metal inner core (as shown in Figure 2).

The handle 1 of the expansion forceps forms an angle of about 90-120 degrees with the expandable tongue part 2, and the length of the tongue part 2 is 6-8 cm. Damage to internal organs. The head end 21 of the tongue part 2 is relatively blunt, which is realized by smooth and connected lines. It adopts the design that the head end 21 is relatively thin and the end 22 is slightly thicker. cm, the short axis is 0.3cm-0.6cm; the long axis of the end 22 is 0.8cm-1.5cm, and the short axis is 0.5cm-1.0cm. The expansion forceps also has a small buckle 3, which is positioned at the end 22 of the tongue, and can buckle the inserted inner core 4. The built-in inner core 4 ends are blunt by adopting a smooth arc surface, and its shape and size are consistent with the clamping of the expansion forceps, and the length is also 6-8cm, making it easier to implant and less likely to be damaged Chest wall and internal vital tissues and organs. The end of the inner core 4 is also provided with an enlarged portion 41, so that the inner core 4 will not slide too deeply after implantation.

In specific use, the sterilized instrument is first combined with expansion forceps, implanted into the built-in inner core, and buckled so that it cannot slide. After disinfection and local anesthesia on the patient's chest, a small skin incision was made, and the subcutaneous tissue and intercostal muscles were simply and bluntly separated with vascular forceps, and then entered into the chest cavity. After the incision was slightly enlarged, the device with an inner core was inserted through the incision Withdraw the inner core, expand the head according to the size of the implanted chest tube, quickly insert the chest tube, push out the expansion forceps, and the operation ends after the chest tube is fixed and the chest guide bottle is connected.

The above description of the embodiments is for those of ordinary skill in the technical field to understand and apply the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described here to other embodiments without creative effort. Therefore, the utility model is not limited to the embodiments here, and the improvements and modifications made by those skilled in the art according to the disclosure of the utility model should be within the protection scope of the utility model.
