Problems solved by technology

[0004] The object of the present invention is to provide an ultrasonic scalpel used in pediatric surgery to solve the above-mentioned background technology. Although the ultrasonic scalpel has more functions than the traditional scalpel, it will still produce a certain amount of surgical waste gas, so it will cause problems. Exhaust gas is discharged by adopting the exhaust gas guiding structure, but in the prior art, the exhaust gas guiding structure is mostly a separate pipeline structure or set in the cutter bar. The former method will occupy a certain amount of surgical space, and the same as the latter method, the exhaust gas adsorption position cannot be convenient. Adjustment, resulting in different adsorption effects for different parts of the operation, and the actual exhaust gas guidance effect is poor

no. 1 example

[0030] see Figure 1-2 , an ultrasonic scalpel for pediatric surgery, including a shell 1 and a transducer 2, the transducer 2 is installed at the right end inside the shell 1, and the transducer 2 is connected to the knife bar 3, and the knife bar 3 is installed inside the shell 1 The left end of the housing 1 is fixed with a handle 4 on the lower end surface of the housing 1, and also includes a waste gas absorption device. The waste gas absorption device includes a smoke hole and a horizontal cylinder 5. The horizontal cylinder 5 is sleeved on the outside of the knife rod 3 and the two are coaxial. distribution, the horizontal cylinder 5 is horizontally slidingly connected to the left end of the housing 1 through the first cross bar 7 and the spring 6, and the right end of the first cross bar 7 extends through the left side wall of the housing 1 to the inside of the housing 1, and the two are slidingly connected , and the right end of the first crossbar 7 communicates with ...

[0034] see Figure 3-7 , the smoke hole in this embodiment is composed of a first air hole 16 and a first air cavity 17, the first air hole 16 is opened in the inner wall on the left side of the horizontal cylinder 5, and the first air cavity 17 is opened in the inside of the horizontal cylinder 5 , the first air cavity 17 communicates with the first air pipe 12 through the first cross bar 7, and the suction device sucks the waste gas from the inner side of the horizontal tube 5 through the first air cavity 17 and the first air hole 16, which is the same as that of the first embodiment The difference is that the position of the first air hole 16 is changed from the outside to the inside of the left end of the horizontal cylinder 5. Since the horizontal cylinder 5 may be very close to the operation area, when the operation area is relatively tight, the first air hole 16 is set at The way inside the horizontal cylinder 5 can effectively prevent the first air hole 16 in the negat...

Abstract

The ultrasonic scalpel comprises a shell and an energy converter, the energy converter is installed at the right end of the interior of the shell and connected with a scalpel rod, the scalpel rod is installed at the left end of the interior of the shell, and a grip is fixed to the lower end face of the shell; the right end of the first cross rod penetrates through the left side wall of the shell and extends into the shell, the interior of the first cross rod is of a hollow structure, the two ends of the hollow structure are connected with the smoke hole and the first air pipe correspondingly, the tail end of the first air pipe is connected with the air suction device, and the air suction device operates to suck out waste gas through the first air pipe and the smoke hole. According to the ultrasonic scalpel for pediatric surgery, a waste gas guide structure is redesigned, the position of a suction structure can be adjusted in real time according to the specific surgical position, the surgical operation requirement is better met, meanwhile, the same power source is utilized, energy is saved, environment is protected, and meanwhile the scalpel device has the wound cooling function and the energy converter cooling function.

Description

technical field [0001] The invention relates to the technical field of surgical equipment, in particular to an ultrasonic scalpel for pediatric surgery. Background technique [0002] In the process of pediatric surgery, for some tissues with high water content and low collagen content, ultrasonic scalpels can generally be used to replace the existing traditional stainless steel scalpels, and the ultrasonic scalpel transducers are used to convert ultrasonic energy into high-frequency The mechanical energy of the vibration, the mechanical energy acts on the cutter head or the cutter bar, thereby cutting the human tissue through the high-frequency vibration, but the existing similar ultrasonic scalpels still have the following problems in actual use: [0003] Although the ultrasonic scalpel has more functions than the traditional scalpel, it will still generate a certain amount of surgical exhaust gas, so the exhaust gas guide structure will be used to discharge the exhaust gas...
