Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to an ultrasonic scalpel surgical smoking device. Background Technology

[0002] An ultrasonic scalpel is a high-frequency electrosurgical device primarily used for cutting biological tissues and closing blood vessels. It features minimal bleeding, less damage to surrounding tissues, and faster postoperative recovery. It cuts and coagulates human tissue without causing side effects such as tissue dryness or burns. No current passes through the body during operation, making it widely used in operating rooms and earning it the nickname "bloodless scalpel."

[0003] An ultrasonic scalpel consists of a handle, an ultrasonic scalpel head at the front end, and a pressure blade. According to clinical observations, when the ultrasonic scalpel is in operation, smoke is generated at the working position where the ultrasonic scalpel head and the pressure blade contact each other, which affects the surgical field of vision. Utility Model Content

[0004] To address the aforementioned shortcomings, this invention provides an ultrasonic scalpel surgery fumigation device that can extract the smoke between the ultrasonic scalpel head and the pressure blade, thus solving the problem of smoke affecting the field of vision.

[0005] An ultrasonic scalpel surgical fumigation device, fitted onto an ultrasonic scalpel, includes a pressure plate and an outer tube. The pressure plate is located at the front end of the outer tube and is used to engage with the pressure plate of the ultrasonic scalpel. The outer tube is hollow and fitted onto the shaft of the ultrasonic scalpel. The wall of the outer tube has a certain thickness and has independent suction and exhaust layers along the length of the ultrasonic scalpel, which are continuous in the length direction of the outer tube. The outer wall of the suction layer has suction holes that communicate with the suction layer, and the outer wall of the exhaust layer has exhaust holes that communicate with the exhaust layer.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4 As shown, an ultrasonic scalpel surgical fumigation device is used to attach to an ultrasonic scalpel. The ultrasonic scalpel includes a handle, a shaft, an ultrasonic scalpel head at the front end, and a pressure blade. The ultrasonic scalpel surgical fumigation device includes a pressure blade connecting plate 1 and an outer sleeve 7. The pressure blade connecting plate 1 is located at the front end of the outer sleeve 7 and is used to engage with the pressure blade; the outer sleeve 7 is used to connect to the shaft.

[0025] The outer tube 7 has a certain thickness. It has an independent suction jacket 5 and an exhaust jacket 6 along the length of the ultrasonic scalpel and they are connected in the direction of the length of the outer tube 7. The outer wall of the suction jacket 5 is provided with a suction hole 9, which is connected to the suction jacket 5. The outer wall of the exhaust jacket 6 is provided with an exhaust hole 8, which is connected to the exhaust jacket 6. The exhaust jacket 6 is connected to the smoke extraction component.

[0026] The pressure knife connecting plate 1 is generally elongated and fitted to the pressure knife, and connected to it. In this embodiment, it is a snap-fit ​​connection. Specifically, the middle of the pressure knife connecting plate 1 is hollowed out to form the pressure knife vent 82, which matches the heat dissipation hole of the ultrasonic scalpel clamping arm for heat dissipation of the clamping arm. Snap-fit ​​plates 3 extend from both sides of the pressure knife connecting plate 1 towards the pressure knife, and are used to snap-fit ​​and tighten the connection with the sides of the pressure knife.

[0027] The outer sleeve 7 is rotatably connected to the pressure blade connecting plate 1 to accommodate an ultrasonic scalpel with a rotatable blade head. In this embodiment, a rotating device 4 is provided at one end of the outer sleeve 7 near the pressure blade connecting plate 1. The pressure blade connecting plate 1 is hinged to the rotating device 4 to accommodate the swinging state during clamping and releasing of the pressure blade. Furthermore, the rotating device 4 is an integral ring shape, with a protrusion on the inner ring. A hinge device is provided on the protrusion, and a groove matching the protrusion is provided at the connection between the outer sleeve 7 and the rotating device 4, allowing the pressure blade connecting plate 1 to rotate on the outer sleeve 7.

[0028] It should be noted that the overall thickness of the rotating device 4 is less than the thickness of the air intake jacket 5 / air outlet jacket 6, and there is a ventilation groove between the two. The gas generated when the ultrasonic scalpel is working can enter the air intake jacket 5 through the ventilation groove without affecting the gas in and out.

[0029] Work style:

[0030] The outer sleeve 7 is fitted onto the ultrasonic scalpel shaft, and the pressure plate 1 is snapped and fixed onto the pressure plate. The pressure plate 1 has a pressure vent 82 for discharging the gas generated by the ultrasonic scalpel clamping arm. Inside the outer sleeve 7, along the ultrasonic scalpel direction, are independent suction jacket 5 and exhaust jacket 6, extending along the length of the outer sleeve 7. Suction jacket 5 draws out the smoke generated during ultrasonic scalpel operation, while exhaust jacket 6 introduces treated gas. Suction holes 9 and 8 are located on the wall of the outer sleeve 7 near the scalpel head. Suction hole 9 connects to suction jacket 5 for further smoke intake, while exhaust hole 8 connects to exhaust jacket 6, through which treated gas is output. In practice, if the smoke generated during ultrasonic scalpel operation is sucked out, it will cause a decrease in abdominal air pressure. If the air pressure is maintained by inflating the gas through another device while the smoke is being expelled, a large number of devices are needed, and an additional abdominal cavity inlet is required, which is quite cumbersome. Therefore, this application sets up a double-layer structure to absorb the smoke while simultaneously introducing clean gas through another double-layer structure. The clean gas introduced can be purified gas or an additional clean gas source; this embodiment does not impose any limitations.

[0031] During operation, the smoke extraction unit is turned on, and the device draws air into the tissue through the suction port 9 and suction jacket 5. After turning on the ultrasonic scalpel main switch, the scalpel head is controlled to cut the tissue. The smoke generated during this process can be effectively drawn in through multiple suction ports on the outer tube head. After gas treatment, a clean gas source is formed, or additional clean gas is output through the exhaust jacket 6 and exhaust port 8.

[0032] Based on clinical experience, this application identifies shortcomings in clinical practice and, through integrated analysis of these shortcomings, designs an ultrasonic scalpel fumigation device that is easy to apply and implement in clinical settings. It is suitable for most hospital operating rooms, can be mass-produced and used, and is expected to have good economic benefits.

[0033] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
