Abstract
This utility model relates to a kind of fixture block for the protection of puncture needle, and it is mainly applicable in the laparoscopic surgery of human body.Of the present utility modelly to be characterised in that: comprise be fixed together fixture block body, spring lead, horizontally slip boss and fixture block lead, described spring lead and fixture block lead are positioned at the two ends of fixture block body, horizontally slip boss and fixture block body is fixed, and the boss that horizontally slips has an inclined-plane.This utility model structural design is more reasonable; when after the broken stomach wall of puncture; under cooperation of the present utility model; the protected slide block of protection slide bar of puncture needle is spacing up and down; when front end is again by external force, also again can not expose piercing blade, blade is in guard mode; ensure that patient can not be subject to unexpected injury because of puncture, use safety, reliable and convenient.
Description
Technical field
This utility model relates to a kind of fixture block for the protection of puncture needle, and it is parts in puncture needle, belongs to medical apparatus and instruments, is mainly applicable in the laparoscopic surgery of human body.
Background technology
In prior art, human abdominal cavity operation widely uses puncture needle, is particularly used in Minimally Invasive Surgery field and laparoscopic surgery.
Chinese utility model patent application number 022492445 discloses one " canula puncture needle "; this puncture needle comprises housing 1, nook closing member 3, sleeve pipe 4, knife bar 6, piercing blade 7, safe sleeve pipe 11, back-moving spring 12 and insurance thimble 24; but its structural design is still reasonable not, really can not play our said protective effect in operation process.Specifically see Fig. 5, when insurance thimble 24 is depressed, whole device is in the state of de-preservation, after wearing out stomach wall, because the cone-shaped nose of safe sleeve pipe 11 is no longer subject to resistance, under the effect of back-moving spring 12, safe sleeve pipe 11 ejects forward, piercing blade is again encased again; In this process, insurance thimble 24 is depressed, although piercing blade 7 encases again always; but when the cone-shaped nose of safe sleeve pipe 11 touches internal organs, front end is under pressure and to after-contraction, exposes again piercing blade 7; lose protective effect, operation use or dangerous.
Owing to not arranging fixture block in the prior art, cause total to design reasonable not, during puncture, there is no protective effect.
Utility model content
Technical problem to be solved in the utility model to overcome in prior art existing above-mentioned deficiency, and provide a kind of reasonable in design simple, coordinate with puncture needle after there is the fixture block for the protection of puncture needle of safeguard protection effect.
The technical scheme in the invention for solving the above technical problem is: should for the protection of fixture block of puncture needle comprise be fixed together fixture block body, spring lead, horizontally slip boss and fixture block lead; described spring lead and fixture block lead are positioned at the two ends of fixture block body; horizontally slip boss and fixture block body is fixed, and the boss that horizontally slips has an inclined-plane.After making this utility model coordinate with puncture needle thus, use more safe and reliable.
Described spring lead described in the utility model is cylindrical, and fixture block lead is tetragon, and fixture block body is one have a place to become the cylindrical of plane at circumferencial direction, and the described boss that horizontally slips is fixed in the plane of this fixture block body.Make this utility model better with the protection slide block of puncture needle with protect slide bar to match, whole puncturing operation can be completed safely and reliably.
The lower surface of the boss that horizontally slips described in the utility model and the lower surface of fixture block body at grade, better with the protection slide block of puncture needle with protect slide bar to match.
This utility model compared with prior art; have the following advantages and effect: structural design is more reasonable; when after the broken stomach wall of puncture; under cooperation of the present utility model, the protected slide block of protection slide bar of puncture needle is spacing up and down, when front end is again by external force; also again piercing blade can not be exposed; blade is in guard mode, ensures that patient can not be subject to unexpected injury because of puncture, use safety, reliable and convenient.

Detailed description of the invention
See Fig. 1-Fig. 4, this utility model forms primarily of fixture block body 11, spring lead 12, horizontally slip boss 13 and fixture block lead 14, spring lead 12 and fixture block lead 14 are positioned at the two ends of fixture block body 11, and the boss 13 that horizontally slips is fixed with fixture block body 11.
In the present embodiment, spring lead 12 is cylindrical, and fixture block lead 14 is tetragon, and fixture block body 11 is one have a place to become plane 111 cylindrical at circumferencial direction, and the boss 13 that horizontally slips is fixed in the plane 111 of this fixture block body 11; Horizontally slip boss 13 lower surface 131 and fixture block body 11 lower surface 112 at grade, and the boss 13 that horizontally slips has an inclined-plane 132.
This utility model is made of plastic.
See Fig. 5, comprise cutter window 2, protection slide bar 3, needle guard main body 4 and protection slide block 5 with protection knife bar mechanism of the present utility model; This utility model is arranged in needle guard main body 4, and spring lead 12 and fixture block lead 14 stretch out needle guard main body 4.
See Fig. 1-Fig. 5, during use, the boss 13 that horizontally slips makes this utility model can horizontally slip in puncture needle; Spring lead 12 can place spring, and fixture block lead 14 makes this utility model move up and down along fixture block lead 14 in puncture needle.
Puncture needle described in literary composition, protection slide bar and protection slide block SEPARATE APPLICATION patent all, no longer describe in detail.
Specific embodiment described in this description, the title that its part is got can be different.All equivalences of doing according to structure, feature and the principle described in this utility model inventional idea or simple change, be included in the protection domain of this utility model patent.
