A kind of tumor biopsy puncture outfitTechnical field
The present invention relates to medical instruments field, is specifically related to a kind of tumor biopsy puncture outfit.
Background technology
Biopsy referred to as " biopsy ", is also known as surgical pathology inspection, referred to as " looking into outside "；Refer to diagnose, treatNeeds, cut from patient's body, clamp to take or puncture etc. and take out pathological tissues, carry out the technology of pathological examination.This is diagnosisMost censorship cases can be made clear and definite histopathological diagnosis by most important part in pathology, by as facingThe final diagnosis of bed.
Nowadays, the incidence of tumour is higher and higher, makes the treatment of tumour more urgent.Tumor biopsy is to make a definite diagnosis tumprigenicityA kind of method, biopsy have being of great significance to matter in diagnosing tumor.Existing tumour is livedProcuratorial organ's formula generally all cuts one piece of tumour to carry out biopsy using biopsy forceps, this biopsy mode later stage need to notch intoThe careful processing of row, prevents malignant tumour from spreading, there are certain risk.Existing tumor biopsy mainly has pin type biopsy and openBiopsy, pin type biopsy usually can not obtain clear and definite pathological examination because tumor tissues are few, and the diagnosis of tumour only needs a small amount ofTumor tissues, the wound that abdominal produces are larger.Endoscope-assistant surgery can reduce wound, and resume speed is fast, for onlyIt is very useful to need for the situation of clear and definite tumour property.But it is not adapted to use in endoscope-assistant surgery at this stage swollenKnurl biopsy device.Existing tumor biopsy device in relatively exposed body overall situation, is unfavorable for preventing from swelling in application processOncocyte is spread and cross-infection；Processing to tumour notch is not proper enough, may cause damage to healthy cell.
The content of the invention
1. technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of tumor biopsy puncture outfit, it can be that tumor biopsy process carryFor the space of relative closure, tumour cell diffusion is can effectively prevent, prevents cross-infection；Processing to tumour notch is more properAnd safety, it will not cause damage to healthy cell, and realize medicine interventional treatment.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that：

In the present embodiment, the side of crotch knife 8 towards the bar hole 1 is provided with camera device 35, and described takes the photographAs being shrouded outside device 35 equipped with transparent protective cover 36.Camera device 35 can realize the visualization of biopsy sampling process, convenient behaviourMake, and protective cover 36 can prevent that camera device 35 from being stain.
The concrete application process of above-mentioned tumor biopsy puncture outfit is：
Under original state, outer knife cylinder 20 is located in liquid cylinder 10, and the cutter accommodating groove 11 of interior knife cylinder 30 is just externalThe bar hole 1 of knife cylinder 20, cutter 14 is in receiving state, and cutter 14 is got lodged on bar hole 2 17；Using puncturing 1 band of bodyDynamic liquid cylinder 10, which punctures, enters tumour region, is at this time moved to spacing ring 6 and attaches the position of human body surface and screwTrip bolt 7；Then Handheld Division 3 21 is promoted, because there is gag lever post 29 to exist so that Handheld Division 2 19 is also promoted, interior knife cylinderBody 30 and outer knife cylinder 20 keep relative position to be pushed out liquid cylinder 10, at this time, if crotch knife 8 turns not in contact with to tumourDynamic 10 global facility of liquid cylinder, after crotch knife 8 stretches into tumour, post-tensioning Handheld Division 2 19, Handheld Division 3 21 moves, interiorKnife cylinder 30 and outer knife cylinder 20 keep relative position to be pulled liquid cylinder 10, and crotch knife 8 is by a part of tumor tissues bandLiquid cylinder 10 is entered, which is located at one 9 region of bar hole, at this time to airbag aeration, makes liquid cylinder10 directions puncture one end relative closure of body 1；Then by handle rotating wheel 31, tense wire rope 15,14 cutter head of cutter toUpper rotation, opens bar hole 2 17, then unclamps steel wire rope 15, and cutter 14, which resets, to be rotated, cutout tumor group in rotation processKnit as tumor sample, when cutter 14 replys receiving state, tumor sample is fallen into sampling cavity 12, and bar hole 2 17 again byCutter 14 blocks；Then post-tensioning Handheld Division 3 21, can extract interior knife cylinder 30 out, take out tumor sample send to inspection afterwards.After taking out tumor sample, interior knife cylinder 30 is turned back in outer knife cylinder 20, it is anti-to the filling of medicinal liquid cavity 4 by medicine-pouring port 241The liquid of tumour, liquid can be pushed to one 9 region of bar hole by injecting bar 23, and tumour notch is carried out at suppressionReason, meanwhile, energization interface 271 is connected into power supply, electric energy is transmitted through conduct piece 28 arrive at tumour where position, to tumour notch intoRow permanent hair styling, auxiliary hemostasis, can so prevent tumour cell from spreading.Then the gas in air bag is released, and promotes promotion handPortion 3 21 is held, Handheld Division 2 19 moves, and interior knife cylinder 30 and outer knife cylinder 20 keep relative position to be pushed out liquid cylinder10, the tumor tissues after processing are put back to, then post-tensioning Handheld Division 2 19, Handheld Division 3 21 moves, interior 30 He of knife cylinderOuter knife cylinder 20 keeps relative position to be pulled liquid cylinder 10, finally extracts liquid cylinder 10 out.
It can be seen from the above, the present invention can carry out tumour isolation cutting, and under isolation notch is carried out permanent hair styling andDrug-treated, security during permanent hair styling is higher, will not cause damage to healthy cell, and realizes medicine interventional treatment, can be effectivePrevent tumour cell from spreading；And the sampling cavity for containing tumor sample can be closed in time, be conducive to prevent cross-infection.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described aboveChange, modification will all fall in scope of the presently claimed invention.
