DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0037] Embodiment one:

[0038] Please refer to Figures 1-5 ​​The present invention discloses a surgical smoke collection device, which specifically includes a negative pressure aspirator, a filter and a negative pressure tube 1 connected in sequence. The negative pressure aspirator and the filter are existing technologies in Changshu. The improvement of the present invention is mainly in the negative pressure tube 1.

[0039] like Figure 1 As shown, the end of the negative pressure pipe 1 is connected to the middle of the outer arc surface of the arc cabinet 3 through a connecting pipe 2 with a square cross section. Arc cabinets 4 are slidably fitted on both ends of the arc cabinet 3. One end of the cabinet 4 is closed, and the other end is fitted on the end of the arc cabinet 3 to achieve expansion and contraction along the arc direction.

[0040] In this embodiment, as Figure 3 and Figure 4 As shown, suction holes 5 are evenly distributed on the inner arc surface of the arc-shaped cabinet 3, and suction holes 6 are evenly distributed on the inner arc surface of the sliding cabinet 4. The opening size and arrangement interval of suction holes 6 correspond to the opening size and arrangement interval of suction holes 5 to ensure the continuity of hole density. Preferably, the hole spacing is 8-12mm.

[0041] Therefore, by adjusting the positions of the two sliding cabinets 4, the effective arc length of the entire suction end can be adjusted to adapt to different incisions and surgical field layouts. For example, the overall arc can be adjusted within the range of 180° to 270°, and the corresponding smoking coverage area expands synchronously with the arc length.

[0042] In this invention, a sealing gasket is fixedly installed at the port of the sliding cabinet 4, and the sealing gasket is in close contact with the curved cabinet 3, thereby ensuring the airtightness between the sliding cabinet 4 and the curved cabinet 3.

[0043] In addition, a protrusion is formed on the inner wall at the port of the sliding cabinet 4. The protrusion is movably locked in the slot. The slot is evenly opened on the outer arc surface of the arc cabinet 3. When the protrusion is locked in the slot, the first suction hole 5 and the second suction hole 6 are in an overlapping state. Thus, when the sliding cabinet 4 is adjusted, the number of "second suction holes 6" that can work effectively on the sliding cabinet 4 is adjusted to avoid sudden changes in hole density during the extension and contraction transition. As the extension of the sliding cabinet 4 increases, the number of second suction holes 6 that can participate in the work increases accordingly, thereby realizing the synchronous expansion of the negative pressure coverage area with the arc length.

[0044] When the overall arc length of the suction end increases, more suction holes 26 can be used; conversely, when the overall arc length of the suction end decreases, fewer suction holes 26 can be used.

[0045] To facilitate pressure equalization and current distribution, in this embodiment, as follows: Figure 1As shown, two side branch pipes 7 are communicated with the negative pressure pipe 1, and the side branch pipes 7 are communicated with the communicating ports 9 on the outer arc surface of the slide cabinet 4 through the hoses 8, so that the negative pressure in the negative pressure pipe 1 acts on the suction end head through the connecting pipe 2 (for the arc-shaped cabinet 3) and the two hoses 8 (for the two slide cabinets 4) together, thereby improving the pressure drop along the way and the left-right pressure balance under the wide arc working condition.

[0046] Preferably, the equivalent inner diameter of the side branch pipe 7 is Φ8-12 mm.

[0047] Embodiment Two:

[0048] Please refer to Figure 2 and Figure 5 On the basis of the embodiment one, this embodiment specifically proposes a mechanism for adjusting the position of the slide cabinet 4, as shown in Figure 5 .

[0049] The two sides of the connecting pipe 2 are fixedly installed with bearing frames 12, and the two bearing frames 12 are rotatably installed with adjusting gears 11, and the two adjusting gears 11 are respectively engaged with the outer arc surfaces of the two slide cabinets 4.

[0050] The two bearing frames 12 are fixedly connected with brackets 13, and the two brackets 13 are rotatably installed with driving gears 14, and the adjusting gears 11 and the driving gears 14 are coaxially installed with synchronous wheels 15, and the two synchronous wheels 15 are connected through a synchronous belt 16.

[0051] The U-shaped slide plate 10 is slidably installed on the connecting pipe 2, and the two sides of the U-shaped slide plate 10 are respectively engaged with the two driving gears 14, so that when the U-shaped slide plate 10 is linearly displaced, the two sides of the driving gears 14 can be rotated, and the synchronous wheels 15 and the synchronous belt 16 are transmitted to the two adjusting gears 11, thereby driving the two sides of the slide cabinets 4 to synchronously and equally extend or retract.

[0052] Therefore, by adjusting the position of the U-shaped slide plate 10, the extension and retraction of the slide cabinet 4 can be adjusted, the equal extension of the two slide cabinets 4 is ensured through mechanical synchronization, the left-right flow deviation is significantly reduced, the pressure balance consistency of multi-point parallel suction is improved, the arc length adjustment is simplified to a single linear action, and the intraoperative adjustment efficiency is improved.

[0053] Embodiment Three:

[0054] Please refer to Figure 6 On the basis of the embodiment one and the embodiment two, in this embodiment, the U-shaped slide plate 10 is fixedly connected with the sleeve 18 through the connecting rod 17, the sleeve 18 is slidably installed on the negative pressure pipe 1, and the other end is rotatably connected with the threaded sleeve 20 through the rotating ring 19, and the threaded sleeve 20 is screwed on the negative pressure pipe 1.

[0055] Thus, by rotating the threaded sleeve 20, the position of the threaded sleeve 20 on the negative pressure pipe 1 is adjusted, i.e. the position of the sleeve 18 is adjusted, and then the position of the U-shaped slide plate 10 is adjusted through the connecting rod 17, so as to finally realize the symmetrical extension and contraction of the two slide cabinets 4. Preferably, the lead of the threaded sleeve 20 can be 1.0-1.5 mm / turn, which is convenient for fine adjustment in the state of wearing gloves.

[0056] Further, as shown in Figure 6 the side air hole 22 is arranged on the negative pressure pipe 1, and the side groove 21 corresponding to the side air hole 22 is arranged on the sleeve 18.

[0057] When the sleeve 18 and the U-shaped slide plate 10 move forward, the arc length of the suction end head is increased, and the effective opening of the side air hole 22 is automatically reduced due to the shielding of the sleeve 18, so as to automatically reduce the side leakage and distribute more negative pressure to the end passage where the air suction hole one 5 and the air suction hole two 6 are located. Thus, even in the case that the number of working air holes increases with the increase of the arc length, the capture speed of the end single hole can basically remain constant, so as to avoid the decrease of suction force or the instability of negative pressure due to the increase of the number of holes, and it is not necessary to additionally adjust the negative pressure aspirator due to the increase of the number of holes.

[0058] Embodiment four:

[0059] The embodiment discloses a use method of a surgical smoke converging collection device, which is used for the surgical smoke converging collection device provided in the embodiments one and two, and specifically includes the following steps:

[0060] Step one, rotate the threaded sleeve 20 to drive the symmetrical extension and contraction of the two slide cabinets 4 through transmission, and adjust to the required arc;

[0061] Step two, hold the negative pressure pipe 1 to place the converging collection device composed of the arc-shaped cabinet 3 and the two slide cabinets 4 at the outer edge of the surgical incision;

[0062] Step three, start the negative pressure aspirator to perform the converging collection of surgical smoke.

[0063] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
