Problems solved by technology

Since surgical instruments such as electric knife are often used in thoracoscopic surgery to resect tissue, it is very easy to generate smoke during the resection process.
The smog produced during this operation interferes with the visual effect of the thoracoscope, which not only affects the surgical field of view, but also causes harm to the medical staff; therefore, the applicant has improved the existing incision protector so that it also has Smoke extraction function

Embodiment 1

[0040] Embodiment 1: The incision protector with smoke exhaust function of the present invention

[0041] refer to Figure 1 to Figure 3-1 , In this embodiment, medical materials such as medical plastic, medical silica gel, or medical polyurethane, or medical polyethylene (PE) are used to manufacture the incision protector with smoke exhaust function of the present invention.

[0042] The incision protector 100 with smoke exhaust function includes an upper positioning ring 1 , a lower positioning ring 2 , a protective film 3 and a smoke exhaust system 4 .

[0043] The upper positioning ring 1 and the lower positioning ring 2 are connected together through the protective film 3; the protective film 3 supports the surgical incision under the expansion of the upper positioning ring 1 and the lower positioning ring 2. Open to form the operation channel 31.

[0044] The smoke exhaust system 4 includes a smoke inlet 41, a smoke exhaust channel 42 and a negative pressure connection...

Embodiment 2

[0060] Example 2: Incision protector with smoke exhaust function of the present invention containing 2 sets of smoke exhaust systems

[0061] refer to Figure 4 to Figure 6 The difference between this embodiment and Embodiment 1 is that, in this embodiment, the incision protector 100 with smoke exhaust function includes two sets of the smoke exhaust system 4 .

[0062] According to needs, the smoke exhaust passages 42 of the two sets of the smoke exhaust system 4 can be designed into different smoke intake methods, thereby increasing the suction capacity of the smoke and other gases generated during the operation, and achieving the purpose of reducing the smoke generated during the operation. Better suction effect of other gases.

[0063] refer to Figure 4 to Figure 4-2 , the smoke inlet 41 of one set of the smoke exhaust system 4 can be designed as a porous smoke inlet on the side of the lower positioning ring 2, and the smoke inlet of the other set of the smoke exhaust sy...

Abstract

The invention discloses an incision protector having a smoke discharge function. The incision protector comprises an upper locating ring, a lower locating ring, a protecting membrane and a smoke discharge system. The smoke discharge system comprises a smoke inlet, a smoke discharge passage and a negative-pressure connecting port. The smoke discharge passage of the smoke discharge system moves downwards along the edge of the upper locating ring, fits to the edge of the protecting membrane and reaches the lower locating ring; and the smoke inlet is arranged on or nearby the lower locating ring.Smoke, which is generated from operations, enters the smoke discharge system via the smoke inlet and is sucked out of a body from the negative-pressure connecting port along the smoke discharge passage, so that interference of smoke to a thoracoscope is avoided and a clear operative field is guaranteed in an operating process; and a good protecting effect can be achieved on patients and doctors, so that the operating process becomes more convenient and safer.

Description

technical field [0001] The invention relates to an incision protector, in particular to an incision protector with smoke exhaust function used in surgical operations. Background technique [0002] Thoracoscopic surgery is a representative operation of thoracic minimally invasive surgery. It uses modern TV camera technology and high-tech surgical equipment to complete the minimally invasive surgical technique of thoracic and dorsal surgery under the chest wall cannula or tiny incision. During the operation, under the guidance of the camera system, the doctor accurately locates and treats the lesion, and resects the tissue that needs to be removed directly under the display of the camera system. Thoracoscopic surgery has been widely used in the surgical treatment of pleural diseases, lung diseases, esophageal diseases, mediastinal diseases and other diseases. [0003] The incision protector is an important auxiliary device used in thoracoscopic surgery. It can play a variety ...
