Description
Technical field
The utility model relates to care implement technical fields more particularly to a kind of biopsy to be set with.
Background technique
Referred to as " biopsy ", also known as surgical pathology inspection referred to as " is examined " outside for biopsy (biopsy)；Refer to and sees patients
Disconnected, treatment needs cut from patient's body, clamp to take or puncture etc. and take out pathological tissues, carry out the technology of pathological examination.It
It is most important part in Diagnosis pathology, specific histopathological diagnosis, quilt can be made to most inspection cases
As clinical final diagnosis.Application range include: puncture extract tissue, as liver, kidney, lymph node puncturing tissue；From lesion
The fritter tissues that position is cut, including the pathological tissues etc. taken with endoscopic forceps such as gastrofiberscope, branchofiberoscopes.
For convenience of tissue is pierced into, existing biopsy tool generally includes needle core and sleeve, and needle core front end is sharp, is longer than set
Cylinder；When puncture, stylophore is pierced into tissue together with needle core, when reaching predetermined lesions position, takes out needle core, is continued rotation and is pierced into set
Cylinder makes the hollow structure of sleeve cut lesion tissue.After completing sampling, extract sleeve, be deposited in lesion tissue in sleeve with
Sleeve takes out.But it is few that this mode leaves and takes the lesion tissue amount in sleeve, it usually needs is pierced into repeatedly；In addition, being covered taking out
Biopsy when cylinder in sleeve is easy abjection, easily causes tumour cell to fall off and sends out.
Utility model content
The utility model is intended to provide biopsy suit, facilitates piercing, and biopsy success rate can be improved.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows:
A kind of biopsy suit, including sleeve, guide wire and the crawl structure being arranged on sleeve, axially sets in the sleeve
There is the guide hole being adapted to guide wire；Guide wire length is greater than the length of sleeve, and guide wire front end is rotary knife shape.
Further, crawl structure includes at least three long-hilt bread-swords, is equipped in the sleeve lateral wall and to be adapted to long-hilt bread-sword
Pilot hole, pilot hole are axially arranged, and guide hole is through-hole, and for long-hilt bread-sword in pilot hole, the length of long-hilt bread-sword is greater than sleeve
Length, the long-hilt bread-sword are arranged around bushing core interval；Long-hilt bread-sword includes handle and arc shape blade, handle front end and arc
The connection of shape blade, arc shape blade end have blade, and inwardly, arc shape blade is elastic blade to arc shape blade end.
Preferably, the rear end of handle is stretched out sleeve and is connect with the same connection ring.
Further, arc shape blade outer rim is blade.
Further, there is serrated face in barrel forward end face.
Compared with prior art, the utility model has the following beneficial effects:
1. guide wire front end is rotary knife shape in the utility model, plays the role of tapping, be inserted into reason convenient for being entirely set with
That thinks takes biopsy site, and sleeve is avoided to be embedded in the shallow normal tissue etc. of table, improves the accuracy for taking biopsy；
2. equipped with crawl structure on sleeve, materials amount is big；And the biopsy in sleeve can be taken out completely, it can also prevent
Biopsy in sleeve falls off when taking out sleeve, improves biopsy success rate；
3. there is serrated face in barrel forward end face, enough depth desireds are inserted into convenient for sleeve.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is outline drawing when grabbing folding structures；
Fig. 3 is the cross-sectional view of Fig. 2；
In figure: 1- sleeve, 2- guide wire, 3- handle, 4- arc shape blade, 5- rotary knife shape, 6- connection ring, 7- serrated face.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Figure 1, 2, 3, biopsy suit disclosed by the utility model, including sleeve 1, guide wire 2 and long-hilt bread-sword, sleeve
The guide hole being adapted to guide wire 2 is axially arranged in 1,1 side wall of sleeve is equipped with the pilot hole being adapted to long-hilt bread-sword, and pilot hole is axial
Setting, guide hole and pilot hole are through-hole；Long-hilt bread-sword can be moved forward and backward in pilot hole along pilot hole.As shown in Figure 2,3,
Long-hilt bread-sword is equipped at least three around 1 center of sleeve；Long-hilt bread-sword includes handle 3 and arc shape blade 4,3 front end of handle and arc shape
Blade 4 connects, and there is a blade at least 4 end of arc shape blade, and inwardly, multiple arcs shape blade 4 is to centre for 4 end of arc shape blade
Close up holding, preferably, 4 outer rim of arc shape blade is blade.
Arc shape blade 4 is elastic blade.As shown in Figure 1, under normal circumstances, arc shape blade 4 is to be hidden in 1 wall of sleeve
Interior.The length of long-hilt bread-sword is greater than the length of sleeve 1, and the rear end of long-hilt bread-sword is stretched out sleeve 1 and connect with the same connection ring 6, even
Connecing ring 6 can hold, and play the role of rotating and be pressed onto bottom, to control stretching and the retraction of arc shape blade 4.Arc shape blade 4
It is hidden in 1 wall of sleeve and puncture is facilitated to enter, the stretching of arc shape blade 4 is encircled, and crawl cutting tissue is facilitated.
2 length of guide wire is greater than the length of sleeve 1, and 2 front end of guide wire is rotary knife shape 5, plays the role of similar tapping, just
It is inserted into entire suit and preferably takes biopsy site, and sleeve is avoided to be embedded in the shallow normal tissue etc. of table, raising takes biopsy
Accuracy.1 front end face of sleeve has serrated face 7, is inserted into enough depth desireds convenient for sleeve 1.
In use, guide wire 2 is inserted into the guide hole of sleeve 1, sleeve 1 is stretched out in 2 front end of guide wire, is inserted to takes work forward
Position is examined, after reaching the depth for taking biopsy, turnbarrel 1, soft tissue enters in sleeve 1, press connection ring 6 forward at this time,
Long-hilt bread-sword moves forward, and loses the limitation of sleeve 1, arc shape blade 4 reverts to arc shape, the arc shape blade 4 of 3 long-hilt bread-swords
It stretches out and encircles, most of " base of a fruit ", then turnbarrel 1 can be cut off, that is, whole bases of a fruit can be cut off, long-hilt bread-sword front end encircles, can hinder
Only the biopsy in sleeve 1 falls off when taking out sleeve 1；Also prevented also from sleeve when materials measure Datong District in can guarantee
Tumour cell, which falls off, sends out, and tumour is avoided to spread.
Certainly, the utility model can also have other numerous embodiments, without departing substantially from the spirit of the present invention and its essence
In the case where, those skilled in the art can make various corresponding changes and modifications, but these according to the utility model
