Description
Technical field
This utility model belongs to the medical apparatus field, and particularly a kind of bone tumor biopsy pin in the human body bone tumour therapy, adopts less invasive techniques to extract the biopsy needle of biopsy samples for a kind of.
Background technology
In treatment bone tumor disease, taking biopsy samples to do pathological diagnosis is primary treatment link.The domestic less invasive techniques that generally all adopts is gathered sample with piercing method at present, and still, existing puncture instrument performance is all not very good, and bone tumor biopsy pin commonly used after the boring of bone wall, also needs the puncture nook closing member is replaced by tubular sampler.This puncture needle is complex operation not only, and sampler to get the rate of obtaining lower.For this reason, another kind of method is namely at first bored the bone wall saturating with marrow puncture needle also by wide selection, pass the bone cinclides that become with the soft tissue biopsy needle again, extract the tumor biopsy sample in the bone, though this method has improved the rate of obtaining of adopting of sample, operation is difficulty relatively.
The utility model content
This utility model provides a kind of bone tumor biopsy pin, and the technical problem that solve is, needn't change other utensils and just can finish whole operations continuously, and sample to get the rate of obtaining very high.This biopsy needle structural design is rationally exquisite, operates convenience ease in use, and sample is got and obtained the rate height.
The technical scheme that adopts is:
A kind of bone tumor biopsy pin comprises pricker, pricker handle, needle tubing and needle tubing handle.
Its technical essential is:
Pricker one end is provided with rhizoma sparganic taper needle point, is positioned at triangular pyramid shape needle point one side on the pricker and offers the sampling groove.
The upper face center of pricker handle is provided with the cylinder boss of integrative-structure, and the other end of pricker is fixed in the cylinder boss.The lateral symmetry that is positioned at cylinder boss at the pricker handle is provided with the alignment pin of integrative-structure.
Needle tubing one end is provided with three arc milling swords, and needle tubing is matched in clearance with the pricker that is installed in the axial hole of needle tubing, and rhizoma sparganic taper needle point is positioned at the outside of three arc milling swords.
The needle tubing handle comprises first cylinder, round platform, second cylinder and rectangular handle.
First cylinder, round platform, second cylinder and rectangular handle are for being fixedly connected successively and a coaxial overall structure.
The other end of needle tubing is fixed in first cylinder and the round platform.
Be provided with blind hole in the round platform, establish notch in second cylinder and the rectangular handle.Blind hole and notch are interconnected.
Offer the alignment pin borehole jack respectively in the rectangular handle of notch both sides, the corresponding assembling with the alignment pin borehole jack of alignment pin.Needle tubing handle lower surface matches with the shape of pricker handle upper surface.
The needle tubing outer wall is provided with length scales.
Described sampling groove is the sampling groove of long and narrow vertical disappearance, and the sampling groove bottom has tangent connection of side curved surface than larger radius of curvature with it, with the rigidity requirement of assurance pricker.
The height of cylinder boss reply pricker produces enough bond stress with the moment of torsion that satisfies pricker and the burden requirement of normal pressure.
Its advantage is:
This biopsy needle structural design is rationally exquisite, operates convenience ease in use, and sample is got and obtained the rate height.

The specific embodiment
A kind of bone tumor biopsy pin comprises pricker 2, pricker handle 11, needle tubing 4 and needle tubing handle 14.
Pricker 2 one ends are provided with rhizoma sparganic taper needle point 1, are positioned at triangular pyramid shape needle point 1 one sides on the pricker 2 and offer sampling groove 15.
The material of pricker 2 is carefully rod of solid rustless steel, and the material of needle tubing 4 is the stainless steel thin-wall tubule.Needle tubing handle 14 and pricker handle 11 all melt pressure injection with polypropylene thermal and form.
The other end of needle tubing 4 is fixed in first cylinder 16 and the round platform 17.
Be provided with in the round platform 17 in blind hole 6, the second cylinders 8 and the rectangular handle 13 and establish notch 7.Rectangular handle 13 is cancelled structure, and blind hole 6 and notch 7 are interconnected.
Offer alignment pin borehole jack 9 respectively in the rectangular handle 13 of notch 7 both sides, the corresponding assembling of endoporus of alignment pin 10 and alignment pin borehole jack 9.Needle tubing handle 14 lower surfaces match with the shape of pricker handle 11 upper surfaces.
The function of alignment pin 10 is: needle tubing handle 14 is assembled the globality of locating and strengthening notch 7 on the needle tubing handle 14 with pricker handle 11.
Moving down pricker handle 11 is separated alignment pin 10 and alignment pin borehole jack 9, pricker handle 11 half-twists, pricker handle 11 upwards advances in the notch 7 of wideer needle tubing handle 14, the sampling groove 15 that pricker handle 11 drives on the pricker 2 exposes needle tubing 4, is the assembled state (as shown in Figure 2) of sampling in the bone.
Notch 7 on the needle tubing 4 and blind hole 6 degree of depth all satisfy the requirement of sampling groove 15 exposure length.Needle tubing 4 outer walls are provided with the length scales 5 of annular black spraying resin.
Operational approach:
1, this biopsy needle is assembled into bore state.
2. the one hand handle of holding with a firm grip makes needle tubing 4 vertically be bored the bone wall, and firmly spinning needle tubing 4 upwards relies on the sense that falls through of hands, judges whether to penetrate the bone wall, and determines needle tubings 4 stops or upwards be advanced into predetermined depth again according to length scales 5.
3, moving down pricker handle 11 breaks away from needle tubing handle 14, pricker handle 11 half-twists, notch 7 related prickers 2 on needle tubing handle 14 are together boosted, sampling groove 15 above the pricker 2 exposes in needle tubing 4 gradually, tumor body in the rhizoma sparganic taper needle point 1 of pricker 2 stings to the marrow, the sampling depth that reaches design stops to advance, and stops the original place.
4, by needle tubing handle 14 needle tubing 4 of slowly boosting, just will the sample bone tumor tissue of groove 15 peripheries of three arc milling swords 3 of needle tubing 4 upper ends is sheared and is included in the space of sampling groove 15 and needle tubing 4 inwalls, stops to advance, and stops the original place.
5, to moving down pricker handle 11 half-twists, with 14 combinations of needle tubing handle, extract needle tubing 4 and pricker 2 synchronously.
6, the live body sample in the collection pricker 2 up-sampling grooves 15.
