One end of the smoking pipe 1322 passes through the outer sleeve 110 directly and is connected with one adapter tube 131, and one end of the drug delivery pipe 1323 passes through the outer sleeve 110 directly and is connected with the other adapter tube 131.

When the smoke at the wound needs to be sucked out, the smoke suction pipe 1322 is opened, the smoke at the wound enters the smoke suction pipe 1322 through the corresponding adapter pipe 131, and is discharged through the smoke suction pipe 1322, so that the clear operation visual field is ensured. When the medicine needs to be delivered to the wound, the medicine delivery pipe 1323 is opened, and the medicine enters the corresponding adapter pipe 131 through the medicine delivery pipe 1323 and then enters the wound through the adapter pipe 131 so as to treat the wound.

Optionally, the pipe diameters of the two adapter pipes 131 are the same or different. That is, the pipe diameter of the adapter pipe 131 corresponding to the drug delivery pipe 1323 may be the same as or different from the pipe diameter of the adapter pipe 131 corresponding to the smoking pipe 1322. The pipe diameter of the adapter pipe 131 is designed according to smoking and drug delivery performance, as long as the smoking and drug delivery functions can be satisfied.

In the above two embodiments, the smoking and drug delivery tubes 132 can both achieve smoking and drug delivery, but the number of the adapter tubes 131 that are matched with each other is different, and the embodiment in which the number of the adapter tubes 131 is one is shown in fig. 1 to 4, and the embodiment in which the number of the adapter tubes 131 is two is not shown.

Specifically, two first sealing members 140 are disposed at two axial ends of the outer sleeve 110, so that the two ends of the outer sleeve 110 are disposed in a closed manner, and the first sealing members 140 can allow the knife shaft assembly 120 to axially pass through. Moreover, the two first sealing members 140 can also serve to support the outer tube 123 after the outer tube 110 and the outer tube 123 are sealingly connected.

Optionally, the first seal 140 is a hermetic terminal. Optionally, the first seal 140 is a seal end cap. Of course, in other embodiments of the present invention, the first sealing element 140 may also be other components capable of supporting and sealing. Optionally, a sealing ring or the like may be further disposed at the contact position of the first sealing member 140 and the outer tube 123.

It should be noted that there is a slight difference between the two first sealing members 140 at the two ends of the outer sleeve 110, based on the direction shown in fig. 1, the first sealing member 140 on the left side has no hole for the adaptor 131 to pass through, as shown in fig. 2, and the first sealing member 140 on the right side has a hole for the adaptor 131 to pass through, as shown in fig. 3.

Referring to fig. 1 to 4, in an embodiment, the knife bar structure 100 further includes a second sealing member 150, and the second sealing member 150 is sealingly disposed at a connection position of the smoking and drug delivery tube 132 and the outer sleeve 110. The second seal 150 is used to ensure a seal between the smoking and drug delivery tube 132 and the outer sleeve 110.

When the number of the adapter tubes 131 is one, the second sealing member 150 is disposed on the connection tube 1321 and seals the connection tube 1321 and the outer sleeve 110. When the number of the adaptor tubes 131 is two, the number of the second sealing members 150 is two, wherein one second sealing member 150 is disposed at the connection between the smoking tube 1322 and the outer sleeve 110, and the other second sealing member 150 is disposed at the connection between the drug delivery tube 1323 and the outer sleeve 110.

It should be noted that the second sealing element 150 and the first sealing element 140 have substantially the same structure and principle, and the second sealing element 150 is modified on the basis of the first sealing element 140 to adapt to the connection between the connecting tube 1321 and the outer sleeve 110. The structure of the second connecting member will not be described herein.

In one embodiment, the adaptor tube 131 is a flexible tube. That is, the adaptor tube 131 is made of a flexible material and has a tubular structure. The flexible adapter tube 131 can facilitate installation of the adapter tube 131 into the outer sleeve 110.

In one embodiment, the outer sleeve 110 has a tube diameter ranging from 7.6mm to 8.8mm. Generally, the diameter of the outer tube 123 of the cutter shaft assembly 120 is 5.5mm, and after the cutter shaft assembly 120 is mounted on the outer sleeve 110, the space between the cutter shaft assembly 120 and the outer sleeve 110 can be penetrated by the adapter tube 131, so that the size of the outer sleeve 110 is reduced as much as possible while the smoking and medicine delivery performance is not affected, and further, the size of the cutter bar structure 100 is reduced.

It can be understood that, in order to reduce the wound surface of the patient to avoid the opening of the abdominal cavity operation from being too large, and further to limit the size of the opening of the abdominal cavity operation, at this time, the size of the whole instrument needs to be reduced as much as possible, so that the pipe diameter range of the outer sleeve 110 is limited to be within the range of 7.6mm to 8.8mm.

In an embodiment, after the cutter shaft assembly 120 abuts against the inner wall of the outer sleeve 110, the maximum dimension between the cutter shaft assembly 120 and the inner wall of the outer sleeve 110 is 1.5mm to 2.2mm. After the outer diameter of the outer sleeve 110 is within the above range, in fig. 2, the size range between the top of the outer tube 123 and the top of the outer sleeve 110 can allow the adapter tube 131 to be installed, so that the adapter tube 131 can smoothly smoke and deliver medicine.

Referring to fig. 1 to 4, the knife bar structure 100 of the ultrasonic scalpel of the present invention integrates detachable smoking and medicine delivery functions, and when smoking is needed, the smoking pipe 1322 can suck out the smoke generated in the operation process through the adapter tube 131 to ensure the clear operation field. When drug delivery is needed, the drug is delivered to the wound through the drug delivery tube 1323 and the adapter tube 131 so as to carry out drug administration treatment on the wound. The switching tube 131 is used as a smoke and medicine circulation channel, so that the smoke in the operation process can be sucked out, the operation visual field is clear, medicine treatment can be performed on the wound in an external medicine delivery mode, and the operation effect is improved to a great extent. The utility model discloses a guide arm structure unites two into one smoking and the structure of dosing, and simple structure is light, still can dismantle when not using.

The utility model provides an ultrasonic scalpel, including tool bit 200, hilt 300, ultrasonic transducer and above-mentioned embodiment cutter bar structure 100, cutter bar structure 100 reaches ultrasonic transducer install in hilt 300, and, cutter bar structure 100 with ultrasonic transducer connects, tool bit 200 install in cutter bar structure 100 is kept away from the tip of hilt 300. The utility model discloses an ultrasonic knife adopts the cutter arbor structure 100 back of above-mentioned embodiment, can also realize the function of smoking and defeated medicine in transmission ultrasonic vibration, guarantees that the operation field of vision is clear, improves operation treatment.
