Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a handheld operating room smoke extraction device and a medical device. Background Technology

[0002] Utility Model Patent Application No. CN202122473114.6 discloses a smoke absorption device for laparoscopic surgery, including a negative pressure tube. A negative pressure suction machine is connected to the end of the negative pressure tube. A suction port is provided on the negative pressure tube, and a suction tube is connected to it via the suction port. A control valve and a filter mechanism are provided on the suction tube, and a suction end is provided at the end of the suction tube. This utility model uses a suction tube with a control valve, which is controlled by the surgeon to regulate the flow rate of the released gas. The smoke generated during surgery is concentrated and absorbed by the negative pressure suction machine, preventing smoke from spreading in the operating room and protecting the health of medical staff. The flow rate can be adjusted to suit different situations, avoiding the suction of carbon dioxide pneumoperitoneum formed in the abdominal cavity, ensuring a clear field of vision during surgery, and guaranteeing surgical safety. It provides excellent protection for both patients and medical staff and is worthy of promotion.

[0003] The aforementioned patent controls the absorption rate by adjusting the angle of the control valve plate through a handle on the control valve, thereby controlling the gas flow rate within the control valve body. However, since the handle is fixed and released through the cooperation of a limiting groove and a limiting spring, medical personnel need to bend down to operate the handle and control its rotation angle in order to adjust the absorption rate, which is inconvenient for medical personnel to operate.

[0004] Therefore, we have made improvements to this by proposing a handheld operating room smoke extraction device and medical instruments. Utility Model Content

[0005] The purpose of this invention is to address the issue that the handle is fixed and released through the cooperation of a limiting groove and a limiting spring, requiring medical personnel to bend down to operate the handle and control its rotation angle in order to adjust the absorption rate, which is inconvenient for medical personnel to operate.

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

[0007] A handheld operating room smoke extraction device to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] The device includes a negative pressure suction machine, which has a connection port on its side. A connector is installed on the inner wall of the connection port. A suction pipe is installed at the smoke inlet of the connector. A suction end is installed at the end of the suction pipe. A suction assembly is provided on the suction end. The suction assembly includes suction heads that are rotatably fitted on both sides of the suction end.

[0010] By setting rotating suction heads on both sides of the suction end, the suction rate can be quickly adjusted. Simply rotate the suction head to adjust the suction rate precisely and quickly, which greatly improves the smoothness of operation during the operation. This allows medical staff to focus more on the operation itself, eliminating the need for them to look down to find and operate the handle, and avoiding the inconvenience caused by shifting their gaze and the risk of possible misoperation.

[0017] A medical device comprising a handheld operating room smoke extraction device as described in any of the preceding claims.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting rotating suction heads on both sides of the suction end, the suction rate can be quickly adjusted. Simply rotate the direction of the suction head to adjust the suction rate accurately and quickly, which greatly improves the smoothness of operation during the operation. This allows medical staff to concentrate more on the operation itself, and eliminates the need for medical staff to look down to find and operate the handle, avoiding the inconvenience of operation caused by shifting their gaze and the risk of possible misoperation.

[0035] Example 1

[0036] Please refer to Figure 1-6A handheld operating room smoke extraction device includes: a negative pressure suction machine 1, a connection port 2 on the side of the negative pressure suction machine 1, a connector 3 installed on the inner wall of the connection port 2, a suction tube 4 installed at the smoke inlet of the connector 3, a suction end 5 installed at the end of the suction tube 4, and a suction assembly 6 provided on the suction end 5. The suction assembly 6 includes suction heads 601 rotatably fitted on both sides of the suction end 5. A connecting cylinder 602 connected to the end of the suction head 601 is installed, and a connecting pipe 603 connected to both sides of the suction end 5 is installed. The connecting cylinder 602 is rotatably fitted on the connecting pipe 603, and the outer wall of both sides of the connecting pipe 603 has through holes 604 that cooperate with the suction heads 601. The inner wall of both sides of the connecting cylinder 602 is equipped with a limiting ring 605, and the outer wall of both sides of the connecting pipe 603 has a limiting groove 606 that rotatably cooperates with the limiting ring 605. Both sides of the bottom of the suction end 5 are equipped with fixing plates 607, and both sides of the two fixing plates 607 are equipped with clamps 608. The suction head 601 cooperates with the clamps 608.

[0037] Implementation process: When the smoke is drawn through the suction head 601 of the suction assembly 6, it first enters the connecting tube 602 through the suction heads 601 on both sides of the suction end 5, and then converges into the suction tube 4 through the connecting pipe 603. The connecting tube 602 and the connecting pipe 603 are designed to rotate and cooperate. When the suction head 601 and the smoke inlet of the suction end 5 are in the same direction, the through hole 604 is connected to the suction head 601, and the suction head 601 is in the open state. When the suction head 601 and the smoke inlet of the suction end 5 are in opposite directions (e.g., ...), the smoke is drawn through the tube 604. Figure 6 With the suction head 601 in a closed state, the clamp 608 on the fixing plate 607 fixes and limits the suction head 601, so that medical staff do not need to bend down to find and operate the handle, avoiding the inconvenience of operation caused by shifting the line of sight and the risk of possible misoperation. By simply rotating the direction of the suction head 601, the suction rate can be adjusted accurately and quickly, which greatly improves the smoothness of operation during the operation and allows medical staff to concentrate more on the operation itself.

[0038] Benefits of implementation: The aspiration rate can be quickly adjusted by setting the rotating aspiration head 601, which improves the smoothness of operation during the operation.

[0039] Example 2

[0040] A filter frame 7 is installed inside the connector 3, and a carbon fiber filter element 8 is installed inside the filter frame 7. Fiber filter cotton 9 is installed near the inner bottom of the filter frame 7 close to the connector 3. Both ends of the suction tube 4 are equipped with internal threaded connectors 10, and both the suction end 5 and the end of the connector 3 inlet are equipped with external threaded connectors 11. The internal threaded connectors 10 and external threaded connectors 11 are threadedly engaged.

[0041] Implementation process: The smoke drawn in from the suction tube 4 first reaches the filter frame 7 inside the connector 3. The carbon fiber filter element 8 uses its fine pore structure to initially adsorb and filter the tiny particles and harmful chemicals in the smoke. Then, the fiber filter cotton 9 further intercepts the remaining impurities, ensuring that the discharged gas is relatively clean and reducing pollution to the operating room environment. The suction tube 4 can be replaced by threading the internal thread connector 10 at both ends and the external thread connector 11 at the inlet of the connector 3 with the suction end 5.

[0042] Benefits of implementation: The dual filtration system composed of carbon fiber filter element 8 and fiber filter cotton 9 in filter frame 7 effectively intercepts harmful substances in surgical smoke.
