Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic scalpels, and in particular to a smoking type ultrasonic scalpel. Background Art

[0002] Ultrasonic scalpel is a high-frequency electrosurgical device, mainly used for cutting biological tissues and closing blood vessels. It has the characteristics of less bleeding, less damage to surrounding tissues, and fast recovery after surgery. It acts on human tissues to cut and coagulate, and will not cause side effects such as tissue drying and burns. No current passes through the human body when the blade is working. It is widely used in operating rooms and is known as a bloodless scalpel. When the ultrasonic scalpel oscillates and cuts coagulated tissue, it will generate a lot of heat to vaporize the operating site and surrounding fluids, seriously obscuring the endoscope lens and affecting the efficiency of the operation. During the operation, there will still be a lot of tissue fluid in the operating site, and blood and other liquids need to be sucked out. An integrated smoking device is used to enter the abdominal cavity and other operating sites, which is not easy to clean and replace. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] (Example 1)

[0024] See Figure 1 and Figure 2 The present invention provides a smoking type ultrasonic surgical knife, which has a housing 1, and the housing 1 is rotatably connected with a universal wheel 2, and the housing 1 is penetrated and fixedly connected with a first tracheal joint 11 and a second tracheal joint 12, and the first tracheal joint 11 and the second tracheal joint 12 are sealed and connected, and the universal wheel 2 is connected with a sleeve assembly through a pin shaft 345, and the sleeve assembly has an inner sleeve 3, an outer sleeve 4, and a knife rod 5, and a universal wheel sealed inner cavity 21 is provided inside the universal wheel 2, and the first tracheal joint 11 is connected to the universal wheel sealed inner cavity 21, and one end of the outer sleeve 4 is provided with an outer sleeve air inlet 31, and the other end of the outer sleeve 4 is provided with an outer sleeve air outlet 32, and the outer sleeve air outlet 32 ​​is connected to the universal wheel sealed inner cavity 21. The universal wheel 2 is clamped with a torque wrench 8. The outer sleeve air outlet 32 ​​is connected to the universal wheel sealed inner cavity 21 through a first hose 71; the first tracheal joint 11 and the second tracheal joint 12 are sealed and connected through a second hose 72. The smoking type ultrasonic scalpel is also provided with a tongue-shaped piece 91 that matches the blade head of the shank 5, a bracket sleeve 92 that connects the inner sleeve 3 and the shank 5, a scalpel wrench 93 for triggering, and other parts, which are regarded as existing conventional technologies and will not be elaborated here, and should not affect the understanding of those skilled in the art. There is a gap between the inner sleeve 3 and the outer sleeve 4. In order to allow the gas and liquid to enter the universal wheel seal cavity 21 smoothly after entering from the outer sleeve air inlet 31, and then be discharged from the universal wheel seal cavity 21 through the second hose 72 and the second air pipe joint 12, the diameter of the outer sleeve 4 is larger than the diameter of the outer sleeve in the prior art, thereby increasing the gap space between the inner sleeve 3 and the outer sleeve 4. The second air pipe joint 12 is located at the upper part of the housing 1, and the second air pipe joint 12 pipeline is externally connected to other mechanisms (such as a negative pressure generator, etc.).

[0025] (Example 2)

[0026] The difference between this embodiment and embodiment 1 is that the universal wheel 2 is provided with a universal wheel outer ring 2a and a universal wheel inner ring 2b, and a universal wheel annular hole 22 corresponding to the first air pipe joint 11 is provided between the universal wheel outer ring 2a and the universal wheel inner ring 2b. This design is to ensure that the normal use and rotation of the universal wheel 2 will not be affected by the obstruction of the first air pipe joint 11.

[0027] In order to match the universal wheel annular hole 22, the universal wheel 2 is provided with a sealing rotation structure corresponding to the first air pipe joint 11, and the sealing rotation structure includes a first sealing plate 61, a ball 62, and a sealing ring 63. The first sealing plate 61 is sealed and connected to the first air pipe joint 11, and the ball 62 is located between the first sealing plate 61 and the sealing ring 63. The sealing ring 63 is sealed and connected to the upper and lower sides of the universal wheel annular hole 22.

Therefore, when the universal wheel 2 rotates, the universal wheel outer ring 2a and the universal wheel inner ring 2b rotate synchronously along the first air pipe joint 11 connected to the first sealing plate 61 through the universal wheel annular hole 22.

[0028] In order to make the universal wheel outer ring 2a and the universal wheel inner ring 2b rotate synchronously, the universal wheel outer ring 2a and the universal wheel inner ring 2b on the universal wheel 2 are also bolted to a second sealing plate 64, and the second sealing plate 64 is located on the left side of the first sealing plate 61. The bolt connection here is not specifically limited, and can be as follows Figure 2 In the embodiment, the second sealing plate 64 is directly bolted to the universal wheel inner ring 2b, a corresponding bolt protrusion ring 2a1 is provided on the universal wheel outer ring 2a, and the second sealing plate 64 is bolted to the bolt protrusion ring 2a1.

[0029] The first sealing plate 61 is a rubber sealing plate, and the sealing ring 63 is a silicone ring. The specific material can be adjusted according to the needs, and no excessive restrictions are made here.

[0030] The length of the second hose 72 is longer than the linear distance between the first tracheal connector 11 and the second tracheal connector 12. The second hose 72 has a reserved portion of length for easy use.

[0031] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. 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.
