DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a disposable LEEP knife containing a smoking device, comprising a shell 1 and two tooth seats 3, a slider 4 is fixedly connected to the right side of the right tooth seat 3, a connecting block 6 is fixedly connected to the left side of the left tooth seat 3, an extraction tube 7 is fixedly connected to the left side of the connecting block 6, a gear 5 is rotatably installed on the middle part of the inner wall of the shell 1, and the adjacent sides of the two tooth seats 3 are respectively meshed and connected with the gear 5, a rotating wheel 8 is rotatably connected to the left side of the bottom of the inner wall of the shell 1, a blade 9 is fixedly connected to the bottom wall of the shell 1, a top shell 10 is provided on the top wall of the shell 1, and a disassembly mechanism 2 is provided on the left and right top walls of the shell 1;
[0030] Specifically, the wall suction device is connected to the top of the extraction tube 7, ensuring that efficient extraction work can be carried out smoothly. This design cleverly utilizes the interaction between the slider 4 and the tooth seat 3. When the slider 4 slides upward along the predetermined track, a tight meshing connection is formed with the gear 5 through the two tooth seats 3, so that the two tooth seats 3 are displaced in opposite directions. When the slider 4 slides to the specified position, the left tooth seat 3 is tightly connected to the extraction tube 7 through the connecting block 6, thereby driving the displacement of the extraction tube 7. This design ensures that the extraction tube 7 can accurately and quickly slide out from the right bottom of the housing 1 so that the wall suction device can perform smoke extraction work. The efficient operation of the wall suction device enables the extraction tube 7 to quickly and effectively extract the smoke generated during the operation. This not only greatly reduces the impact of smoke on medical staff and patients, but also significantly improves the clarity of the surgical field of view. This improvement not only improves the efficiency and accuracy of the operation, but also helps to reduce the occurrence of surgical complications, thereby ensuring the safety and health of patients.
[0031] Reference Figure 1 and Figure 3 The disassembly mechanism 2 includes two rotating plates 201, and the adjacent sides of the two rotating plates 201 are respectively rotatably connected to the left and right top walls of the housing 1. The top rear sides of the two rotating plates 201 are provided with locking grooves 202, and the left and right sides of the top shell 10 are provided with engaging grooves 203. The tops of the two rotating plates 201 are respectively engaged with the corresponding engaging grooves 203. The left and right ends of the rear side of the top shell 10 are fixedly installed with spring locking members 204, and the front ends of the two spring locking members 204 are respectively engaged with the corresponding locking grooves 202; the rear sides of the two spring locking members 204 are fixedly connected with handles 205;
[0032] Specifically, by pulling the two spring locking members 204, their front ends are separated from the locking grooves 202 provided on the rear sides of the two rotating plates 201. The key to this process lies in the interaction between the spring locking members 204 and the locking grooves 202. The design of the spring locking members 204 allows them to have a certain elasticity and locking force. When they are tightly combined with the locking grooves 202, they can effectively fix the position of the rotating plates 201, thereby ensuring the stability and safety of the outer shell 1 and the top shell 10. Next, we rotate the two rotating plates 201 so that their top ends are separated from the engaging grooves 203 provided on the left and right sides of the top shell 10. When the rotating plates 201 are successfully rotated and separated from the engaging grooves 203, the connection between the top shell 10 and the outer shell 1 is released, thereby achieving the purpose of disassembly, making it easy to disassemble and replace, and avoiding repeated disinfection.
[0033] Reference Figure 1, the left and right sides of the housing 1 are both provided with arc surfaces, and the left and right sides of the housing 1 are both fixedly connected with protection pads 12; the front bottom of the housing 1 is fixedly connected with an indicating protrusion 13; the right side of the slider 4 is provided with a protective shell 15, and the left side of the protective shell 15 is rotatably connected to the right side of the housing 1 through a hinge;
[0034] Specifically, the two curved surfaces and the protective pad 12 make it more comfortable to hold, the indicating protrusion 13 makes it easier to identify the direction, and the protective shell 15 allows the slider 4 to be protected and fixed.
[0035] Reference Figure 2 , a plurality of anti-slip bumps 14 are fixedly connected to the right side of the slider 4 at equal intervals; a rubber ring 11 is fixedly installed on the top of the outer wall of the extraction tube 7, and the outer wall of the rubber ring 11 is fixedly connected to the inner wall of the top shell 10;
[0036] Specifically, the static friction of the slider 4 is increased by a plurality of anti-skid protrusions 14, thereby reducing the possibility of hand slippage, and the rubber ring 11 can protect the connection between the extraction tube 7 and the top shell 10, thereby reducing wear.
[0037] Working principle: When starting to use, the top of the extraction tube 7 is connected to the wall suction device so that the extraction work can be carried out. By sliding the slider 4 upward, the two tooth seats 3 are displaced in opposite directions, and then the two tooth seats 3 are meshed and connected with the gear 5, so that the left tooth seat 3 drives the extraction tube 7 to move through the connecting block 6, so that under the rotation of the rotating wheel 8, the extraction tube 7 can slide out from the right bottom of the shell 1, and then the wall suction device is turned on so that the extraction tube 7 can extract smoke, thereby reducing the impact of smoke on doctors and patients. The clarity of the surgical field of view is improved, so as to achieve the purpose of improving surgical efficiency and reducing complications, and by pulling the two spring locking pieces 204, the front ends of the two spring locking pieces 204 are separated from the locking grooves 202 provided on the rear sides of the two rotating plates 201, and by rotating the two rotating plates 201, the top ends of the two rotating plates 201 are separated from the engaging grooves 203 provided on the left and right sides of the top shell 10, thereby completing the purpose of disassembling the top shell 10 and the outer shell 1, thereby facilitating the disassembly and replacement of the outer shell 1, avoiding repeated disinfection, and reducing the material and manpower for repeated disinfection.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
