Embodiment 1

[0040] Such as Figure 1 to 3 As shown, a smoke-free ultrasonic knife includes a control device, a suction device 1 and an ultrasonic knife 2. The control device includes a switch 3, a power device, and a transmission device 4. The power device is connected to the transmission device 4, so The switch 3 is electrically connected to the power device and the negative pressure generator. The suction device 1 includes a negative pressure generator and a suction component 11. The negative pressure generator is electrically connected to the control device. The suction component 11 coincides with the shaft center of the ultrasonic knife 2, the inner diameter of the tube of the suction component 11 is greater than the maximum diameter of the outer tube of the ultrasonic knife 2, and the suction component 11 is in sealed communication with the negative pressure generator; One end of the suction component 11 is in transmission connection with the transmission device 4 and forms a seal, and...

Embodiment 2

[0050] Smoke-free ultrasonic knife as described above, such as Figure 5 As shown in the schematic structural diagram of the cross section of the suction part and the housing of the smoke-free ultrasonic knife provided by the present invention, the suction part 11 is provided with a first protrusion 16 at one end close to the housing 12, and the housing 12 is close to the housing 12. A second protrusion 19 is provided inside one end of the attracting member 11. When the attracting member 11 and the housing 12 are close to each other, the first protrusion 16 and the second protrusion 19 form a transmission connection, and A sealing member 14 is provided at the contact between the attracting member 11 and the housing 12. The transmission connection here is specifically a gear transmission connection. The first protrusion 16 and the second protrusion 19 are complementary nested, and when the attraction member 11 rotates, the housing 12 is driven to rotate synchronously. The sealin...

Embodiment 3

[0052] Such as Figure 3 to 7 As shown, a tubular sealed connection device 6 is provided between the housing 12 and the negative pressure generator, the housing 12 is provided with a fence-shaped second communication member 15, and the sealed connection device 6 is provided on the first Outside the two communicating parts 15, the inner wall of the sealing connection device 6 is provided with a soft material, and the inner diameter of the sealing connection device 6 is equal to the outer wall diameter of the housing 12. The soft material is preferably rubber. The second connecting member 15 is a fence-shaped gap and is arranged on the housing 12. The sealed connection device 6 includes a first member 61 and a second member 62, and the first member 61 and the second member 62 pass through The detachable fixed connection forms the sealed connection device 6, the sealed connection device 6 completely covers the second communication member 15, so that the entire suction device 1 is...

Abstract

The invention discloses a smog-free ultrasound knife. The smog-free ultrasound knife comprises a control device, a suction device, a housing and an ultrasonic knife body. The control device comprises a switch, a power unit and a transmission unit, the power unit is connected with the transmission unit, the switch is electrically connected with the power unit and a negative pressure generator, the suction device comprises the negative pressure generator and a suction part, the negative pressure generator is electrically connected with the control device, the suction device coincides with the axis of the knife bar of the ultrasonic knife body, the inner diameter of the pipe of the suction device is larger than the largest diameter of the outer pipe of the ultrasonic knife body, the suction device is communicated with the negative pressure generator in a sealing manner, one end of the suction device is in transmission connection with the transmission unit to form the seal, the other end of the suction device is in transmission connection with the housing to form the seal, and the suction device is arranged in the housing. During the cutting process of the ultrasonic knife body, the suction device can play a role in cleaning the operation visual field, and the safety and fluency of operations can be improved.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, and in particular to a smoke-free ultrasonic knife. Background technique [0002] The application of ultrasound is usually to transform or transfer ultrasound energy into biological tissues through terminal effects or surgical equipment, which produces some physiological effects, especially the use of the generated heat to cauterize and cut tissues. In the surgical instrument ultrasonic knife, the generator generates high-frequency electric energy, and the transducer uses piezoelectric materials or electromagnetically induced compression materials to convert the high-frequency electric energy into mechanical vibration, and the vibration is amplified and transmitted to the end effector. [0003] The shortcomings of the ultrasonic knives currently on the market are: 1. When the cutter head mechanically oscillates at the ultrasonic frequency to cut the tissue, it will generate high heat at the cu...
