Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of an adaptive smoking high frequency electrode according to an embodiment of the present utility model. Fig. 2 shows a partial axial cross-sectional structural view of the structure shown in fig. 1. Fig. 3 shows an enlarged schematic view of the structure of fig. 2 at a. An embodiment of the present utility model provides an adaptive smoking high-frequency electrode, including: handle 10, cutter head 20, smoke tube 30 and elastic member 40. The handle 10 is provided with a passage 11, a smoke discharge portion 12 communicating with the passage 11, and a through hole 13 provided on a side wall of the handle 10 and communicating with the passage 11. The fume extractor 12 is intended to be connected to an external suction device (not shown in the figures). A cutter head 20 is attached to the distal end of the handle 10. The smoke suction pipe 30 is slidably sleeved on the handle 10 along the axial direction of the handle 10 (as shown by arrow S in fig. 1), and the cutter head 20 is at least partially exposed outside the smoke suction pipe 30. The inner wall of the smoke suction pipe 30 and the outer wall of the handle 10 are enclosed to form a smoke suction flow passage which is communicated with the through hole 13. The elastic members 40 are respectively connected to the smoking pipe 30 and the handle 10, and provide elastic force to the smoking pipe 30 in the axial direction of the handle 10.

The distal end refers to the end of the handle 10 that is closer to the surgical site during the surgical operation, whereas the proximal end refers to the end of the handle 10 that is closer to the doctor.

In the above-mentioned self-adaptive smoking high-frequency electrode, in the course of operation, the cutter head 20 exposed outside the smoke tube 30 can act on the tissue to make various treatments, the smoke tube 30 can be kept close or tightly attached to the tissue at any time, when the cutter is contacted with the tissue, the smoke produced by the cutter can be instantaneously sucked into the smoke tube 30, can not escape, and can be introduced into the smoke channel, and can be introduced into the channel 11 through the through hole 13, and can be outwards extracted by the smoking portion 12. In addition, since the smoke tube 30 is connected to the handle 10 by the elastic member 40 and slidably disposed in the axial direction of the handle 10, the greater the cutting depth of the cutter head 20, the greater the degree of compression of the smoke tube 30 by the tissue and the more the cutter head 20 is exposed, whereas the lesser the cutting depth of the cutter head 20, the less the degree of compression of the smoke tube 30 is; in any event, however, the tube 30 automatically adapts to and closes against the tissue and is immediately drawn away when smoke is generated by the tissue. Therefore, the self-adaptive smoking function can be realized, the smoking is strong, the smoke is not escaped, the visual field is clear, and the operation convenience is greatly improved.

Referring to fig. 1 to 3, in one embodiment, the smoke tube 30 is coaxially disposed with the handle 10, so that the sliding effect of the smoke tube 30 is smoother. It should be noted that the coaxial arrangement is not strictly coaxial above mathematics, but allows for corresponding process errors due to insufficient precision of the machining process and the assembly process, which may be set according to practical requirements, e.g. controlled within 5 °.

The first and second connection portions 311 and 14 are arranged at opposite intervals in the axial direction of the handle 10, and the elastic member 40 is connected between the first and second connection portions 311 and 14. Thus, when the depth of the cut tissue of the cutter head 20 increases, the smoking pipe 30 moves in the axial direction accordingly, the distance between the first connecting portion 311 and the second connecting portion 14 decreases so that the elastic member 40 is further compressed, or the distance between the first connecting portion 311 and the second connecting portion 14 increases so that the elastic member 40 is further elongated. In addition, when the cutter head 20 is gradually withdrawn from the tissue, the smoking pipe 30 is simultaneously restored by the elastic force of the elastic member 40.

In one embodiment, the handle 10 includes a tube 17 connected to the distal end of the second connection portion 14. The through hole 13 is opened on the pipe 17.

Alternatively, the smoke exhaust 12 may be flexibly disposed on the handle 10 according to actual requirements, and may be disposed at the proximal end of the handle 10 as shown in fig. 1, so as to facilitate the whole of the sucked smoke to be drawn out, and not interfere with the tissue when disposed at the distal end of the handle 10; of course, the smoke discharging portion 12 may be disposed at a middle portion or a distal portion of the handle 10, which is not limited thereto.
