Description

Inflatable double-leaf protected thoracoscopic trocar

technical field

The invention relates to a medical device, in particular to an inflatable double-leaf protective thoracoscopic trocar.

Background technique

The trocar (Trocar) is a necessary auxiliary surgical instrument in laparoscopic surgery. It helps the laparoscope not to be polluted when it enters and exits the incision, and reduces the incision damage caused by the lens repeatedly entering and exiting the incision.

However, the Trocars used in the existing thoracoscopic surgery are all laparoscopic Trocars, so that there is a large damage to the intercostal blood vessels and nerves. In addition, the existing Trocars all have the problem that once the incision bleeds, the blood will stay along the Trocar wall. Pollution of the lens down will slow down the operation process; at the same time, when the distal end or close to the chest wall is observed during the operation, the endoscope is upwardly warped and compresses the chest wall tissue (especially when using a 0-degree endoscope), resulting in damage or bleeding that is difficult to observe and handle during the operation , resulting in an increased risk of secondary surgery and postoperative pain aggravation.

Contents of the invention

The technical problem to be solved by the present invention is to provide an inflatable double-leaf protective thoracoscopic puncture device, which can well drain the bleeding of the incision and reduce the pollution of the thoracoscopic lens. While the intervascular nerves are protected from damage, there is a certain compression and hemostasis effect on the incision itself; secondly, the airbags inside the double-opening flaps will form a protective cushion to cushion the upturn of the laparoscopic lens and avoid damage to the inner chest wall. .

To achieve the above object, the technical scheme of the present invention is as follows:

An inflatable double-leaf protective trocar for thoracoscopy, including a hollow tube, the end of the hollow tube is provided with a pair of clamping arms that rotate around a fixed axis and an air bag that drives the clamping arms to clamp the lens of the thoracoscope mechanism.

Preferably, the clamp arm is composed of a long flap and a short flap, and an air cavity is provided on the inner side of the long flap and the short flap and the end surface of the hollow tube body. When the air cavity is filled with gas, The long flap and the short flap rotate around the fixed shaft to a relaxed state until they are tightly connected with the thoracoscopic lens arranged at the bottom of the hollow tube body.

Preferably, when the long and short flaps are in a relaxed state, colloid is provided on the surface closely connected with the thoracoscopic lens.

Preferably, the ends of the long and short flaps are each provided with a groove for placing a control wire, and the control wire controls the contraction and relaxation of the long and short flaps.

Preferably, when the short flap is in a relaxed state, it forms an angle of 45 degrees with the thoracoscopic lens.

Preferably, when the long flap is in a relaxed state, it forms an angle of 30 degrees with the thoracoscopic lens.

Preferably, a gas opening and closing port is provided on one side of the air cavity, and a control device for controlling the flow of gas and a pressure detection device are connected through a soft tube.

Preferably, the hollow tube body is provided with a notch for passing the soft tube and the control wire near the operating side of the handle.

Preferably, a knob-type cap is provided on the top of the hollow tube.

Preferably, the double flaps and the body of the present invention are made of stainless steel, and the air cavity is made of general medical rubber.

Through above-mentioned technical scheme, beneficial effect of the present invention is:

1. The double-leaf design can well drain the bleeding from the incision, reduce the pollution of the thoracoscopic lens, and make the operation process smoother;

2. The integrated inflatable airbag design forms an all-round protection for the surgical incision under the support of the double leaf, that is, the Trocar body airbag design protects the intercostal blood vessels and nerves from damage, and at the same time, there is a certain pressure on the incision itself Hemostasis; secondly, the airbag inside the double leaf will form a protective pad to cushion the upturn of the laparoscopic lens and avoid damage;

3. According to the characteristics of thoracoscopic surgery, the double-leaf design with large front and small rear is reasonably designed, which effectively increases the protection area of the front; at the same time, the double-leaf design effectively prevents Trocar from protruding during the operation and avoids incision damage caused by repeated entry and exit ;

4. The inner diameter design of this patent is suitable for almost all endoscopic lenses in China, and can be fully applied to all parts of the country; in addition, the Trocar sleeve has a knob-type cap design, which makes the installation, disassembly and replacement of the airbag easy, without cumbersome training, and has conducive to universal access;

5. The front elevation angle of the double-leaf leaf included in this patent design is 30°. Compared with the current 30° thoracoscope, it can observe the front from a full angle and further avoid the compression of the chest wall by the lifting of the endoscope. In addition, the design of the rear elevation angle of 45° is sufficient for endoscopy. Watch below.

6. The double-leaf body of this patent design is made of stainless steel and can be used repeatedly; the airbag is designed as a general medical silicone, which only needs to be replaced every time it is used, which is significantly cheaper than the current disposable Trocar.
