Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a smoke-filtering puncture device. Background Technology

[0002] An abdominal paracentesis device is a medical instrument primarily used to insert into the peritoneal cavity through the abdominal wall. In conjunction with minimally invasive equipment, it provides an instrument channel for minimally invasive abdominal and pelvic surgeries. An abdominal paracentesis device typically consists of a puncture needle and a sheath; some devices may also include a handle, connectors, and other components for easier handling and operation by the physician. Abdominal paracentesis devices are generally made of stainless steel and / or polymer materials to ensure durability and safety.

[0003] Although modern abdominal paracentesis devices can filter smoke, this requires an external smoke extraction and filtration system. If the connection between the external smoke extraction and filtration system and the paracentesis device is not tight, smoke leakage may occur.

[0004] Therefore, it is of great significance to provide a smoke-filtering puncture device to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a fume-filtering trocar to address the problem that while current abdominal trocars can achieve fume filtering, they rely on an external fume-filtering device. If the connection between the external fume-filtering device and the trocar is not tight, fume leakage may occur, and harmful fume gases within the abdominal cavity may not be filtered out. Simultaneously, it provides surgical personnel with a clearer surgical view.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0030] Please see Figure 1-4 The present invention provides a technical solution for a smoke-filtering puncture device: including a puncture rod head 1, a puncture rod base 2, an air inlet 3, an air inlet valve 4, an air outlet valve 5, a puncture device sleeve 6, and a puncture rod 7.

[0031] The puncture rod head 1 is installed at the top of the puncture rod 7, the puncture rod base 2 is installed at the top of the puncture device cannula 6, the air inlet 3 is installed on the side of the puncture rod base 2, and the air inlet valve 4 is installed on the air inlet 3.

[0032] The vent valve 5 is installed on the front of the puncture rod base 2;

[0033] The puncture cannula 6 is fitted onto the bottom end of the puncture rod 7.

[0034] The puncture rod base 2 has a cavity inside, which is connected to the top of the puncture tube 6. A sealing diaphragm 8 is installed inside the cavity.

[0035] The front of the puncture rod base 2 is provided with vent hole 2 12, vent hole 11 and air outlet 9, and vent hole 2 12, vent hole 11 and air outlet 9 are located below the sealing diaphragm 8.

[0036] A valve cavity is provided on the front of the puncture rod base 2. The air outlet valve 5 is slidably connected to the valve cavity, and the inner diameter of the valve cavity is larger than the outer diameter of the air outlet valve 5.

[0037] One end of each of the exhaust port 2 12, exhaust port 11, and air outlet 9 is connected to the cavity. A filter element 10 is installed on the side of the cavity near the exhaust port 2 12, exhaust port 11, and air outlet 9. The other end of each of the exhaust port 2 12, exhaust port 11, and air outlet 9 is connected to the valve cavity.

[0038] The top and bottom ends of the exhaust valve 5 are respectively provided with sealing block 13 and sealing block 2 14.

[0039] In practical use, first insert the puncture rod 7 from the top of the puncture rod base 2 into the trocar cannula 6, then insert the trocar into the abdominal cavity, and then pull out the puncture rod 7. After connecting the air inlet 3 to the air source, open the air inlet valve 4 to connect the pneumoperitoneum machine and inject gas into the patient's abdominal cavity. When expelling gas, open the air outlet valve 5 according to the amount of smoke. When the amount of smoke is small, pull the air outlet valve 5 outward by half a distance. At this time, the middle end face of the air outlet valve 5 is separated from the air outlet 9, and the smoke is discharged from the air outlet 9 after being filtered by the filter element 10. When the smoke... When the amount of mist is large, the vent valve 5 is fully opened. At this time, the sealing block 14 disengages from the vent 12, and the sealing block 13 disengages from the vent 11. The smoke is then filtered through the filter element 10 and discharged from the vent 12, the vent 11, and the vent 9. This solves the problem of harmful smoke and gas generated during laparoscopic surgery, giving medical staff a clearer surgical view, enabling them to perform surgery more accurately, reducing blind spots, and protecting the health of medical staff. At the same time, no external filter device is required, avoiding smoke leakage.
