Problems solved by technology

However, when the electric knife cuts the burned tissue, it also produces a lot of surgical smoke
These fumes not only block the surgeon's vision and affect the operation, but also contain chemical components such as hydrocarbons, nitriles, organic amines and aldehydes, which endanger the health of surgical personnel
At present, in clinical practice, surgical assistants are generally allowed to hold traditional suction devices to eliminate smoke, which wastes a certain amount of human resources and may cause certain interference to the operation.

Embodiment 1

[0014] see Figure 1-Figure 6 , a ring-shaped smoke aspirator on the incision protective cover, which is composed of a ring-shaped suction pipe 1, a ring-shaped slot 2, a connecting pipe 3 and an opening 4, and its material is medical elastic silicone. The annular suction tube 1 is an annular hollow tubular structure, and the openings 4 are evenly distributed on the inner wall of the annular suction tube 1, so that surgical smoke can be inhaled in all directions (such as figure 2 and Figure 5 shown). Said annular slot 2 is an annular semi-tubular structure, its size is slightly larger than the annular suction tube 1, located directly below the annular suction tube 1 and integrally connected (such as Figure 1-Figure 3 As shown), the annular slot 2 has elasticity, and rubber or silica gel can be selected for use. Press the annular card slot 2 on the elastic circular ring of the incision protective sleeve by hand, the annular card slot 2 is stretched, and after the elastic ...

Embodiment 2

[0016] During the operation, after the incision protective cover is fixed, you can choose the ring-shaped smoke aspirator of the corresponding specification according to the size of the incision protective cover, and buckle the annular card slot 2 of the annular smoke aspirator on the elastic circular ring of the incision protective cover fixed (see Figure 6 ), connect the suction tube at one end of the connecting tube 3 of the suction device, and connect the negative pressure suction device, and the assembly is completed. During the operation, due to the effect of the negative pressure suction device, a negative pressure will be formed around the surgical incision, and the surgical smoke generated by the electric knife will be sucked into the opening 4 on the annular suction tube 1, and pass through the annular suction tube 1, The connecting tube 3 and the external suction tube are recovered.

Abstract

The invention provides an annular smoke aspirator on a slit protection sleeve. The annular smoke aspirator is composed of an annular aspiration tube, an annular clamping groove, a connecting tube andholes. The annular aspiration tube is of an annular hollow tubular structure, and the holes are evenly distributed in the inner wall of the annular aspiration tube. The annular clamping groove is an annular semi-tubular structure, has the diameter larger than the that of the annular aspiration tube, is located directly below the annular aspiration tube and is integrally connected, and one end of the connecting tube is in communication with the annular aspiration tube. The smoke aspiration device is matched with slit protectors of various sizes, can be fixed to the incision protective sleeve, does not need to be supplemented by a surgical assistant during the operation, saves labor resources, does not occupy additional space, does not interfere with the operation, saves operation time and reduces the operation cost. The aspiration tube is in a ring shape and is externally connected with a vacuum aspiration device, smoke generated in an operation area can be effectively aspirated comprehensively, can be prevented from interfering with the operation and harming the health of operation personnel.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an annular smoke aspirator on a protective incision cover. Background technique [0002] High-frequency electric knife is an electrosurgical instrument that replaces traditional mechanical scalpel. It can cut tissue quickly and effectively stop bleeding, so it is more and more widely used in surgical operations. However, when the electric knife cuts the burned tissue, it also produces a lot of surgical smoke. These fumes not only block the surgeon's vision and affect the operation, but also contain chemical components such as hydrocarbons, nitriles, organic amines and aldehydes, which endanger the health of surgical personnel. At present, clinically, the surgical assistant is generally allowed to hold the traditional suction device to eliminate the smoke, which wastes a certain amount of human resources and may cause certain interference to the operation. The incisi...
