Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present inventionIn accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment isThe a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the artThe every other embodiment obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
See Fig. 1, shown in 2, a kind of hepatopathy section abdominal paracentesis auxiliary device described in the embodiment of the present invention, including base 2And support, propping up and be set up on base 2, also include illuminating lamp 12, fixing device 9 and hold down gag, support includes the first expansion link 5With the second expansion link 7, the second expansion link 7 bottom is located at by illuminating lamp 12；First expansion link 5 is vertically located on base 2, and second stretchesBar 7 level is located at the top of the first expansion link 5；Hold down gag includes guide rod 13, spring 6, bearing 10 and pressing plate 8；Guide rod 13 erectsDirect puncture crosses the second expansion link 7, and is slidably connected with the second expansion link 7, and it is outside that spring 6 is sheathed on guide rod 13, and upper end is connected to theOn two expansion links 7, lower end is fixedly connected on the bottom of guide rod 13；Guide rod 13 and pressing plate 8 are connected by bearing 10；Fixing device 9Including clamping bar 905, connecting rod the 902, the 3rd expansion link the 11, the 4th expansion link 903 and fixing bar 904；3rd expansion link 11 is verticalIt is fixedly connected on the second expansion link 7 bottom；Fixing bar is fixedly connected on the 3rd expansion link 11；Clamping bar 905 has 2, and symmetricalIt is located at the both sides of the 4th expansion link 903；Clamping bar 905 is respectively hinged at the two ends of fixing bar 904；4th expansion link 903 is fixing evenIt is connected on fixing bar 904；Connecting rod 902 has 2, and is symmetrically set in the both sides of the 4th expansion link 903；Live in connecting rod 902 one endIt is automatically connected on the 4th expansion link 903；The other end is movably connected on clamping bar 905.
Two clamping bars 905 are provided with some notches 901 varied in size in symmetric position.Clamp different size of with thisPuncture needle.
Pressing plate 8 is the convex structure that Open Side Down.Can preferably adapt to human body, preferably human body be pushed down.
It is additionally provided with one on base 2 and punctures needle tray 4, be provided with one block of Magnet 3 puncturing bottom needle tray 4.Puncture for folding and unfoldingPin, Magnet 3 can adsorb puncture needle, prevent loss.
Illuminating lamp 12 is set to emergency light.
The bottom of base 2 is provided with roller 1, it is simple to the movement of whole device.
Operation principle: regulate the first expansion link 5 and length of the second expansion link 7, then pull-up pressure before puncture as requiredPlate 8, then rotates pressing plate 8 and is pressed on human body to suitable position, thus under the pressure of spring 6, fixing human, prevent peopleThe movement of body.After puncture terminates, regulate the 3rd expansion link 11 length, fixing device 9 is moved to the position of puncture needle, then rootSelect different notches 901 according to the size of puncture needle, then regulate the 4th expansion link 903 length, thus under the effect of clamping bar 905Compress puncture needle.
