Description

Technical Field

[0001] The present invention belongs to the technical field of ultrasonic scalpels, and in particular relates to an ultrasonic scalpel protection mechanism. Background Art

[0002] Ultrasonic cutting hemostatic knife is a kind of knife used in surgical operation. Its working principle is: the driving handle converts electrical energy into ultrasonic mechanical vibration and outputs it to the knife head. The knife head chuck clamps the tissue to make the tissue tense. Under the action of ultrasonic mechanical vibration, the hydrogen bonds of cell proteins in the tissue break and the cells disintegrate, thereby achieving the purpose of cutting tissue and stopping bleeding. It has the characteristics of less bleeding, less damage to surrounding tissues, and fast postoperative recovery. It acts on human tissue to cut and coagulate, and will not cause side effects such as tissue drying and burns. When the knife head is working, no current passes through the human body. It is widely used in operating rooms and is known as a bloodless scalpel.

[0003] At present, the blade head of an ultrasonic scalpel can be sterilized when it is reused. However, the handle at the rear end of the blade head is expensive and is easily damaged if it is frequently sterilized.

[0023] In the description of the present invention, it is necessary to understand that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Working principle: The ultrasonic knife protection mechanism, after the ultrasonic knife is used, moves the push plate 29 upward by the push rod 28, and cooperates with the connecting rod 30 to push the two guide blocks 25 to move in opposite directions, and the guide blocks 25 squeeze the support spring 27, so that the two clamps 26 are separated from each other. After the two clamps 26 are adjusted to a suitable position, the blade head and the handle of the ultrasonic knife are inserted into the protective cover 2. At this time, the handle of the ultrasonic knife is located between the two clamps 26, and the push rod 28 is released. The support spring 27 is reset, and the two guide blocks 25 and the clamps 26 are pushed to move toward each other. The two support springs 27 support the two guide blocks 25 respectively, so that the two clamps 26 are tightly attached to the two sides of the ultrasonic knife handle, thereby fixing the position of the ultrasonic knife, avoiding the handle of the ultrasonic knife from tilting due to external force, causing the ultrasonic knife to fall, thereby causing damage to the ultrasonic knife, and at the same time, cooperate with the support box 1 and the support frame 23 to stably support the ultrasonic knife, and then the blade head and the handle of the ultrasonic knife are fully protected by the protective cover 2; After the ultrasonic scalpel is fixed in position, the rotating motor 4 and the water suction pump 6 are started, the water suction pump 6 extracts the disinfectant in the liquid storage tank 3 through the water suction pipe 7, and injects the disinfectant into the guide plate 11 through the guide pipe 8, and then sprays the disinfectant on the blade head and handle of the ultrasonic scalpel through the nozzle 12. At the same time, the rotating motor 4 drives the driven gear 9 and the guide pipe 8 to rotate through the driving gear 5, and the guide pipe 8 drives the guide plate 11 and the nozzle 12 to rotate, and the disinfectant is fully sprayed on the blade head and handle of the ultrasonic scalpel. While fully protecting the blade head and handle of the ultrasonic scalpel, they are also fully disinfected, ensuring that the ultrasonic scalpel is safer during subsequent use; The waste liquid generated by disinfection is quickly discharged into the waste liquid tank 16 through the drain pipe 14, and the waste liquid is collected through the waste liquid tank 16 to facilitate subsequent centralized treatment of the waste liquid. After the ultrasonic scalpel is disinfected, the rotating motor 4 and the water suction pump 6 are turned off, and multiple heating tubes 13 are started at the same time to heat the space inside the protective cover 2. After the blade head and handle of the ultrasonic scalpel are disinfected, the disinfectant on the surface is quickly dried to avoid water stains remaining on the blade head and handle of the ultrasonic scalpel, and the high temperature can further sterilize the blade head and handle of the ultrasonic scalpel. After drying, the heating tube 13 is turned off. When the ultrasonic scalpel needs to be taken out, the push plate 29 is moved upward by the push rod 28, and the connecting rod 30 is used to push the two guide blocks 25 to move in opposite directions, so that the two splints 26 are separated from the handle of the ultrasonic scalpel, and then the ultrasonic scalpel is taken out from the protective mechanism.
