Adjustable electrotome smoke-absorbing device for surgical operation

Abstract

An adjustable electrotome smoke-absorbing device for surgical operation comprises a handle, an adjustable smoke-absorbing pipe and an electrotome. The adjustable smoke-absorbing pipe, which is an integrated through pipe, comprises a front pipe section and an adjustable pipe section. An opening of the front pipe section is adjacent to the front end of the electrotome. The front pipe section is extended or contracted to link the wall of the adjustable pipe section to be extended and lengthened or contracted and shortened, so as to change the distance of the opening from the adjacent front end of the electrotome. The aperture of the opening of the front pipe section is smaller than the diameter of the integrated pipe. The adjustable pipe section is extended beyond the rear end of the handle by more than one centimeter in the rearward direction.

Description

technical field [0001] The present invention relates to an adjustable electric knife smoking device for medical operation, especially for the ventilation and smoking during electrocautery operation. The pipe wall of an adjustable smoking pipe is stretched and stretched to change the position of the mouth of the pipe, and the diameter of the pipe mouth is smaller than its diameter. An integrally connected pipe diameter and a medical operation adjustable electric knife smoking device extending backward. Background technique [0002] Traditionally known electrocautery knives will generate a lot of burning smoke in the process of surgical treatment of body diseases. The reason is that when the electric cautery knife touches body tissue, whether it is electric current or heat, it is used for hemostasis or cutting Tissues will produce carbonization reaction when the electric knife touches the tissue, and this is the visible smoke. [0003] This kind of smoke has been proven to be...

Problems solved by technology

However, during this kind of electrosurgical surgery, in addition to the burning and cutting that will cause smoke and blurred vision, the thick smoking pipe above the electrosurgical unit will also block the doctor's line of sight from paying attention to the location of the lesion during the operation, especially if When performing minimally invasive surgery, the surgical incision is small. Once the electric knife penetrates into the body, the smoking pipe is on top and the electric knife is below. From the line of sight, the thick smoking pipe almost completely covers the electric knife. , if it causes adverse results such as cutting errors, or wrong positions for bleeding and hemostasis, the patient may cause irreversible results

[0007] And the design of the smoking pipe in this case, as shown in Figure 4, Figure 5, and Figure 8, it can be clearly seen that it is a double sleeve pipe, and the rear end is simply directly connected to a tail pipe, and there is no other design

In this way, the problem with the design of a double cannula is that there will be gaps between the layered tubes of the cannula. When performing electrosurgical surgery, not only smoke will be sucked, but blood will also be sucked up. If there is a gap in the cannula, blood and water will leak through it

And if the rear end is simply directly connected to a tailpipe, there will also be blood and smoke back seepage problems, especially after the operation is over and the back end suction machine is turned off, the blood water back seepage problem will be more obvious, causing contamination of the surgical site , infection and other serious problems
