Background

The thoracentesis is an operation for the patients with pleural effusion or pneumatosis to extract the effusion or pneumatosis through thoracentesis so as to achieve the purpose of diagnosing and treating diseases. The main complications of thoracentesis include organ injury, hemopneumothorax, pleura reaction, chest infection, etc. The main reasons are as follows: pneumothorax is often caused by injury to intercostal blood vessels or damage to lung tissue; infection in the thoracic cavity is caused by bacteria due to non-strict disinfection during puncture; psychological factors can induce pleural reaction, which is clinically manifested as chest distress and pain, rapid increase in heart rate, dizziness and other discomforts. The complications are caused by not only the reasons of unskilled manual operation techniques but also immature factors in the design of the thoracentesis device.

A common thoracic cavity puncture instrument bag comprises a needle tube, a base, a latex tube, an injector and other main parts. The front end of the needle tube is in a sharp inclined plane shape, and the rear end of the needle tube is a base and is connected with the latex tube. During the puncture process, the puncture needle punctures the chest wall tissue into the thoracic cavity by the sharp inclined plane. If drainage is needed, the drainage tube is placed into the thoracic cavity after skin expansion or blunt dissection. This operation typically requires an experienced specialist and can take a long time to perform. Improper surgical procedures can also lead to the following complications: 1. the needle tip punctures the intercostal blood vessels or lung tissue to cause hemorrhage or pneumothorax; 2. after the accumulated liquid or the accumulated gas is pumped every time, the rubber tube needs to be clamped, and pneumothorax is easy to occur.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 6, the puncture outfit comprises a puncture outfit body casing 3, an integrated chest tube 16 detachably sleeved outside the puncture outfit body casing 3, and a puncture outfit core 1 with one end slidably sleeved inside the puncture outfit body casing 3, wherein a tray 5 is slidably arranged inside the puncture outfit body casing 3 along the length direction, and one end of the puncture outfit core 1 is fixedly connected with one side surface of the tray 5; an air bag 8 is further arranged in the poking and clamping main body sleeve 3 and positioned in the other side face of the tray 5, a concave part is arranged on one side face, close to the tray 5, of the air bag 8, an exhaust plug 13 is embedded in the wall of the air bag 8 of the concave part, and the exhaust plug 13 keeps a closed state under the condition of no stress; one end of a needle tube 7 penetrates through the exhaust plug 13 in a sliding manner, and the other end is fixedly provided with a disc-shaped exhaust port 15; the disc-shaped air outlet 15 abuts against the soft rubber pad 12 fixedly provided on the other side surface of the tray 5.

Further, a sliding support 6 is arranged on the inner pipe wall of the poking card main body casing 3, and the section of the sliding support 6 is triangular; the sliding support 6 is used for preventing the tray 5 from moving in two directions, so that after the puncture of the puncture needle core 1 is finished again, the tray 5 is clamped by the sliding support 6 to stop sliding forwards continuously, and the thoracic viscera and blood vessels are prevented from being damaged by puncturing too deeply.

Further, a spring 4 is sleeved outside the fixed position of the poking and clamping puncture needle core 1 and the tray 5; the length of the spring 4 is longer than that of the poking card puncture needle core 1; after the air bag is deflated and collapses, the trocar puncture needle core 1 retreats into the trocar body sleeve 3 under the reaction force of the spring.

Furthermore, one end of the needle tube 7 is a blind end, and a plurality of air inlet holes 14 are formed in the side wall; ensure that the air bag 8 leaks air due to incorrect staying position of the needle tube 7 before puncture.

Further, a hard tail wire 10 is fixedly arranged at the tail end of the poking card main body sleeve 3; 2 foldable joints 9 are arranged on the hard tail wire 10; so that the puncture can be performed while rotating.

Further, a soft tail 11 is fixedly connected to the end of the hard tail 10.

Further, the front part of the poking card main body casing 3 is provided with a threaded tip part 2; the front end of the integrated chest tube 16 is in a fish mouth shape; the threaded tip 2 facilitates the expansion of the puncture opening for the entry of the integrated chest tube 16.

The utility model discloses a theory of operation:

firstly, when thoracocentesis is performed; after the integrated chest tube 16 and the hard tail wire 10 are folded into a Z shape at the foldable joint 9, the puncture is carried out while spirally rotating, the poking and clamping puncture needle core 1 is stressed to downwards drive the tray 5 to downwards move together, and slides over the sliding support 6, and the soft rubber cushion 12 fixed below the tray 5 downwards moves together.

Secondly, the soft rubber pad 12 is continuously rotated to exert force, the soft rubber pad is contacted with the disc-shaped exhaust port 15 above the needle tube 7, the needle tube 7 is pushed to move downwards together, the air bag 8 is gradually stressed and then compressed, when the puncture needle core 1 of the poking card punctures the thoracic cavity, the air bag 8 reaches the maximum supporting force, most of the needle tube 7 enters the air bag 8, and the air inlet 14 also enters the air bag 8; before puncture, the air inlet 14 of the needle tube 7 is positioned in the air exhaust plug 13, the air inlet 14 is blocked, and the air bag 8 can not exhaust air; as shown in fig. 5.

Thirdly, when the puncture needle core 1 of the poking card is punctured into the chest cavity, the puncture needle core 1 of the poking card disappears instantaneously due to the resistance of front puncture, the bottom of the tray 5 is acted by the upward rebounding force of the air bag 8, and the tray moves upwards for a certain distance, moves to the position of the sliding support 6 and is blocked; at the moment, the soft rubber cushion 12 is separated from the disc-shaped exhaust port 15 of the needle tube 7, and the gas in the air bag 8 enters from the air inlet hole 14 of the needle tube 7 and is rapidly discharged from the disc-shaped exhaust port 15; as shown in fig. 6.

At this time, the air bag 8 shrinks and the tray 5 loses the upward pressure of the air bag 8. The spring 4 which is connected below the poking card puncture needle core 1 and keeps a compressed state rebounds instantly to retract the poking card puncture needle core 1 into the poking card main body casing 3; as shown in fig. 3.

The integrated chest tube 16 is tightly attached to the special notch structure design of the poking card main body casing tube 3 in a buckling connection mode, and enters the thoracic cavity together with the poking card main body casing tube 3. After the puncture is made into the thoracic cavity, the flexible tail wire 11 is pulled to pull the poke main body casing 3 out of the integrated chest tube 16. The integrated chest tube 16 left on the chest cavity can be connected with a common water-sealed bottle or a drainage bag to complete the subsequent drainage work.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
