Embodiment 1

[0027] Such as figure 1 , figure 2 Shown, a human necrotic tissue remover for debridement of pancreatitis. This human necrotic tissue remover comprises a tube body 1, a controller 2 and an internal pressure external monitor 7, the tube body 1 is provided with an air inlet 3 and an outlet 4, and the tube body 1 is provided with a partition plate 16 Separated flushing chamber 5 and absorption chamber 6, the air inlet 3 communicates with the flushing chamber 5 and is connected to the positive pressure air source through the trachea, the positive pressure air source is a carbon dioxide insufflation machine 18, and the outlet 4 is connected to the absorption chamber The channel 6 communicates with and is connected to the negative pressure gas source through the air pipe, the negative pressure gas source is an air pump 19, and the gas valve 21 is respectively arranged on the air inlet 3 and the discharge port 4, and the gas valve 21 is a gas on-off valve, and the gas valve 21 is ...

Embodiment 2

[0030] The cross-sectional area of ​​the absorption channel 6 is three times that of the flushing channel 5 . The gas valve 21 is a pressure reducing valve. All the other are with embodiment 1. When the internal pressure external monitor 7 detects that the internal pressure of the human body is too high, the controller 2 controls the air valve on the air inlet 3 to switch to a decompression state, and the pressure-reducing gas continues to be input, while the air valve on the outlet 4 remains normal When the internal pressure of the human body returns to normal, the controller 2 controls the air valve on the air inlet 3 to resume normal conduction; when the internal pressure monitor 7 detects that the internal pressure of the human body is too small, the controller 2 controls the air The air valve on 3 remains in normal conduction, and the pressure gas continues to be input, while the air valve on outlet 4 is switched to a decompression state. When the internal pressure of th...

Embodiment 3

[0032] Such as image 3 , Figure 4 As shown, the end of the absorption cavity 6 is provided with a large tissue blocking net 20 . A radial support rod 14 is fixed near the end of the absorption cavity 6, and a cutter 15 is rotatably connected to the radial support rod 14. The cutter 15 includes a rotating shaft and twisted fan blades, and the twisted fan blades are evenly distributed on the rotating shaft. The partition 16 in front of 15 is provided with a communication hole 17 connecting the flushing channel 5 and the absorption channel 6 , and the communication hole 17 is obliquely directed to the cutter 15 .

[0033] The intake air flow in the flushing chamber 5 is diverted from the communication hole 17 to impact the front of the twisted fan blade of the cutter 15, and the exhaust air flow in the absorption chamber 6 also acts on the front of the twisted fan blade, thereby driving the cutter The rotating shaft of 15 rotates directionally, and the twisted fan blade also ...

Abstract

The invention discloses a human necrotic tissue remover, including a tube body and a controller, wherein the tube body is provided with an air inlet and an air outlet; the tube body is provided with aflushing cavity passage and an absorption cavity passage separated by a partition plate; the air inlet is communicated with the flushing cavity passage and is connected with a positive pressure air source; the air outlet is communicated with the absorption cavity passage and is connected with a negative pressure air source; and the air inlet and the air outlet are respectively provided with an air valve; and the air valve is electrically connected with a controller. The invention utilizes the gentle impact of the airflow to wash and clean the necrotic tissue, reduces the hard contact injury of the instrument to the human body, on the other hand, the air inlet and exhaust rate can maintain the dynamic balance, maintain the stability of the internal pressure of the human body, avoid the adverse consequences to the human body, improve the safety of the debridement operation, and improve the debridement operation efficiency at the same time.

Description

technical field [0001] The present invention relates to a kind of medical equipment, more specifically, it relates to a kind of necrotic tissue remover of human body. Background technique [0002] Some visceral inflammations and abscesses are critical diseases that seriously endanger human health, such as pancreatitis, renal abscess, etc. These diseases usually require surgical treatment, and endoscopic surgery is gradually becoming the mainstream treatment method for such diseases. For example, the treatment of severe acute pancreatitis and peripancreatic infection mostly uses percutaneous nephroscopic transperitoneal surgery. The stripped necrotic tissue and pus generated during the operation need to be removed and discharged in time. The existing necrotic tissue removal equipment and removal methods have limitations and risks, and it is easy to cause adverse consequences such as bleeding and iatrogenic organ damage. The fundamental reason is that the instrument is diffic...
