Abstract
This utility model relates to a kind of protection slide bar for puncture needle, and it is mainly applicable in the laparoscopic surgery of human body.Of the present utility modelly to be characterised in that: it comprise be fixed together the body of rod, circumference positive stop lug boss, up and down positive stop lug boss, slide anteroposterior boss and spring eye, be fixed with circumference positive stop lug boss, up and down positive stop lug boss and slide anteroposterior boss respectively on the top of the described body of rod, spring eye opens the top at the body of rod; Described slide anteroposterior boss is adjacent with upper and lower positive stop lug boss, and the outer surface of slide anteroposterior boss and the horizontal center line of spring eye vertical.Structural design of the present utility model is more reasonable; when after the broken stomach wall of puncture; the protected slide block of protection slide bar 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.
Description
Technical field
This utility model relates to a kind of protection slide bar for 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 protection slide bar 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 a kind of reasonable in design is provided, coordinate with puncture needle after there is the protection slide bar for puncture needle of safeguard protection effect.
The technical scheme in the invention for solving the above technical problem is: this protection slide bar being used for puncture needle is characterized in that: it comprise be fixed together the body of rod, circumference positive stop lug boss, up and down positive stop lug boss, slide anteroposterior boss and spring eye, be fixed with circumference positive stop lug boss, up and down positive stop lug boss and slide anteroposterior boss respectively on the top of the described body of rod, spring eye opens the top at the body of rod; Described slide anteroposterior boss is adjacent with upper and lower positive stop lug boss, and the outer surface of slide anteroposterior boss and the horizontal center line of spring eye vertical.After making this utility model coordinate with puncture needle thus, after the broken stomach wall of puncture, the protected slide block of this utility model is spacing up and down, and when front end is again by external force, also again can not expose piercing blade, blade is in guard mode, safe and reliable.
Body of rod bottom described in the utility model has hole clipping, makes the connection of the body of rod and puncture needle cutter window more convenient.
Slide anteroposterior boss described in the utility model is designed with inclined-plane, so as with the fixture block in puncture needle and protect slide block to coordinate.
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; the protected slide block of protection slide bar 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.

Detailed description of the invention
See Fig. 1-Fig. 5, this utility model mainly comprises the body of rod 11, circumference positive stop lug boss 12, up and down positive stop lug boss 14, slide anteroposterior boss 13 and spring eye 16, be fixed with circumference positive stop lug boss 12, up and down positive stop lug boss 14 and slide anteroposterior boss 13 respectively on the top of the body of rod 11, spring eye 16 opens the top at the body of rod 11; Slide anteroposterior boss 13 is adjacent with upper and lower positive stop lug boss 14, and the outer surface 131 of slide anteroposterior boss 13 and the horizontal center line 17 of spring eye 16 vertical; The body of rod 11 bottom has hole clipping 15, when this hole clipping 15 uses and cutter window 2 clamping of puncture needle; Slide anteroposterior boss 13 is designed with inclined-plane 132.
This utility model is made of plastic.
During use, anterior cutter window 2 clamping with puncture needle of the body of rod 221 of the present utility model, rear portion and needle guard main body 3 are socketed; Circumference positive stop lug boss 12 limits the circular-rotation of this utility model in puncture needle; upper and lower positive stop lug boss 14 limits this utility model moving up and down in puncture needle; slide anteroposterior boss 13 makes the protection slide block slide anteroposterior in puncture needle, mounting spring in spring eye 15.
Puncture needle described in literary composition, fixture block 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.
