Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated, wherein, direction of the present invention is taking Fig. 1 as standard.
As depicted in figs. 1 and 2, vacuum extractor of the present invention comprises suction catheter 1, negative pressure source 2 and guard 3, the centre of suction catheter 1 is formed with runner 11 along its length, the two ends up and down of runner 11 are all opening setting, one end (bottom) of the runner 11 of suction catheter connects negative pressure source 2, guard 3 is arranged on the other end of suction catheter, and guard 3 covers the opening of the runner 11 of suction catheter completely.Wherein, employing following proposal is paid the utmost attention in the installation of guard 3: guard 3 is arranged on mount pad 4, the intermediate formation of mount pad 4 has slide opening 41, suction catheter 1 is inserted in slide opening 41, suction catheter 1 can slide up and down along slide opening 41, can also between guard 3 and the suction side of suction catheter 1, be provided with soft connection strap 5, to avoid suction catheter 1 to come off in slide opening 41.
In carrying out the eliminating of wound hydrops, can make guard 3 in closure state (receipts net state) by mount pad 4, then the suction side of suction catheter 1 is extend in wound, then utilize mount pad 4 to make guard 3 in open configuration, in the time having bulk sludged blood and pus piece in discovery wound, utilize guard 3 to crush relatively large sludged blood and the pus piece in wound, restart negative pressure source.Like this, sludged blood after crushing and pus piece can see through guard 3 and enter in runner 11, so that sludged blood, pus piece and hydrops get rid of along runner, and, in drain process, the guard 3 opening makes to have certain distance between suction port and histoorgan wall, thereby avoid suction port negative pressure to cause histoorgan mechanical damage, before drain or after drain completes, guard 3 tightens up, can make suction catheter 1 smoothly by less wound or breach, be convenient to carrying out of Minimally Invasive Surgery.
Further, as shown in Figure 3 and Figure 4, the exterior contour of runner 11 of the present invention (inwall of suction catheter 1) is horn-like, and its small end is towards negative pressure source 2 one end (lower end), and the inwall of suction catheter 1 is provided with the first helix projection 12.Like this, in removing drain, the suction port of suction catheter 1 (top) is extend in wound, open negative pressure source 2, drain (sludged blood, pus piece and hydrops) just can flow downward along runner 11, because runner 11 is horn-like, and the inwall of suction catheter 1 can also arrange the first helix projection 12, drain can rotate along runner 11 in mobile process, the sludged blood that some are relatively large and pus piece in the process of drain by moulding, facilitate its drain eliminating by runner 11 completely, avoid sludged blood and the pus piece of bulk to stop up runner 11.
Further again, as shown in Figure 5 and Figure 6, the suction catheter 1 of vacuum extractor of the present invention can also adopt following proposal to realize: the exterior contour (inwall of suction catheter 1) of the runner 11 of suction catheter 1 of the present invention is horn-like, its small end is towards negative pressure source 2 one end (lower end), a tube core 6 is set the runner 11 of suction catheter 1 is interior, tube core 6 adopts porous film material to make, the exterior contour of tube core 6 is arranged to stepped, its small end is towards the suction port of suction catheter 1, the inwall of the outer wall of tube core 6 or suction catheter 1 arranges the second helix projection 63, the intermediate formation of tube core 6 has another runner 61, top (suction port end) sealing of another runner 61, its bottom is opening setting, runner 11 and another runner 61 adopt same axis core structure, the sidewall of tube core 6 upper ends is formed with at least one liquid drain hole 62 communicating with another runner 61, the bottom of another runner 61 connects negative pressure source 2 or directly connects another negative pressure source 21, between guard 3 and tube core 6, be provided with connection strap 5.Like this, in removing drain, the suction port of suction catheter 1 (top) is extend in wound, open negative pressure source 2 (or simultaneously opening negative pressure source 2 and another negative pressure source 21), drain just can flow downward along runner 11, because the inwall (or outer wall of tube core 6) of suction catheter 1 is horn-like, and the outer wall of tube core 6 is provided with the second helix projection 63, in mobile process, drain can rotate along runner 11, attraction is in the process of rotating between the inwall of suction catheter 1 and the outer wall of tube core 6, sludged blood and pus piece are got rid of along runner 11, hydrops removes along another runner 61 separation panels of tube core 6, and, when sludged blood and pus piece excessive and stop up when runner 11, can hydrops be removed along another runner 61 separation panels of tube core 6 by the liquid drain hole of perforated membrane tube core 6 62, to reach the object of abundant removing hydrops.
The foregoing is only preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, in implementation process, may there is local small structural modification, if various changes of the present invention or modification are not departed to the spirit and scope of the present invention, and within belonging to claim of the present invention and equivalent technologies scope, the present invention is also intended to comprise these changes and modification.
