Abstract
The utility model provides a tumour biopsy pjncture needle, it contains cavity puncture needle 1, tumor tissue thief hatch 2, tumor tissue sampling device 3, needle tubing cover arm 4, pushes away medicine push rod 5 and drug injection mouth 6, lower extreme one side of duty cavity puncture needle 1 is provided with tumor tissue thief hatch 2, and its inside is provided with 3, cavity puncture needle 1 of tumor tissue sampling device cover has 4, cavity puncture needle 1's on the needle tubing cover arm top to be provided with drug injection mouth 6, medicine push rod 5 and the cooperation of cavity puncture needle 1 piston. Its simple structure has combined to intervene and has alternated the needle, has realized that the tumour is inside to gather, and the wound is little, and the danger coefficient is little, can also pour into the medicine simultaneously into and realize the treatment of intervention formula, inhibition of tumor cells diffusion.
Description
Technical field:
This utility model relates to technical field of medical instruments, is specifically related to a kind of tumor biopsy puncture needle.
Background technology:
Biopsy is called for short " biopsy ", also known as surgical pathology inspection, is called for short " examining outward "; Refer to the needs should diagnosed, treat, cut in patient body, clamp and to get or pathological tissues is taken out in puncture etc., carry out the technology of pathological examination.This is most important part in Diagnosis pathology, can make clear and definite histopathologic diagnosis to most censorship case, by as clinical final diagnosis.
Biopsy tool in diagnosing tumor is of great significance, existing tumor biopsy mode, generally biopsy forceps is all adopted to cut one piece of tumor to carry out biopsy, but this biopsy sample mode later stage needs to carry out careful process to otch, prevent malignant tumor from spreading, cumbersome, there is certain risk.
Utility model content:
The purpose of this utility model is to provide a kind of tumor biopsy puncture needle, and its structure is simple, and combine and get involved interspersed pin, achieve inside tumor collection, wound is little, and danger coefficient is little, and can also realize insertion type treatment by injection of medicine, inhibition tumor cell spreads simultaneously.
In order to solve the problem existing for background technology, this utility model is by the following technical solutions: it comprises hollow puncture needle tubing 1, tumor tissues thief hatch 2, tumor tissues sampling apparatus 3, needle tubing cover arm 4, pushes away medicine push rod 5 and infusion of medicine mouth 6, report hollow puncture needle tubing 1 side, lower end be provided with tumor tissues thief hatch 2, its inside is provided with tumor tissues sampling apparatus 3, hollow puncture needle tubing 1 cover has needle tubing to overlap arm 4, the top of hollow puncture needle tubing 1 is provided with infusion of medicine mouth 6, and medicine push rod 5 and hollow needle tubing 1 piston that punctures coordinates.
Described tumor tissues sampler 3 is cylindrical structural, and its arranged outside has several tumor tissues scraper 7, and the inner side of tumor tissues scraper 7 is provided with tumor tissues collecting tank 8.
This utility model operational approach: first tumor biopsy puncture needle is inserted in tumor, then rotating puncture needle by hand-held cover arm drives tumor tissues sampler to rotate, tumor tissues sampler is scraped by tumor tissues scraper and is collected in tumor tissues collecting tank from some cell tissue, then tumor tissues sampler is extracted out, by infusion of medicine mouth, drug injection is carried out to tumor cell as required.
This utility model has following beneficial effect: its structure is simple, and combine and get involved interspersed pin, achieve inside tumor collection, wound is little, and danger coefficient is little, can also effectively prevent cross infection simultaneously, alleviate the work difficulty of medical worker.
Accompanying drawing illustrates:
Fig. 1 is this utility model structural representation;
Fig. 2 is the end view drawing of this utility model tumor tissues sampler 3.
Detailed description of the invention:
Referring to Fig. 1-2, this detailed description of the invention is by the following technical solutions: it comprises hollow puncture needle tubing 1, tumor tissues thief hatch 2, tumor tissues sampling apparatus 3, needle tubing cover arm 4, pushes away medicine push rod 5 and infusion of medicine mouth 6, report hollow puncture needle tubing 1 side, lower end be provided with tumor tissues thief hatch 2, its inside is provided with tumor tissues sampling apparatus 3, hollow puncture needle tubing 1 cover has needle tubing to overlap arm 4, the top of hollow puncture needle tubing 1 is provided with infusion of medicine mouth 6, and medicine push rod 5 and hollow needle tubing 1 piston that punctures coordinates.
Described tumor tissues sampler 3 is cylindrical structural, and its arranged outside has several tumor tissues scraper 7, and the inner side of tumor tissues scraper 7 is provided with tumor tissues collecting tank 8.
This utility model operational approach: first tumor biopsy puncture needle is inserted in tumor, then rotating puncture needle by hand-held cover arm drives tumor tissues sampler to rotate, tumor tissues sampler is scraped by tumor tissues scraper and is collected in tumor tissues collecting tank from some cell tissue, then tumor tissues sampler is extracted out, by infusion of medicine mouth, drug injection is carried out to tumor cell as required.
This utility model has following beneficial effect: its structure is simple, and combine and get involved interspersed pin, achieve inside tumor collection, wound is little, and danger coefficient is little, can also effectively prevent cross infection simultaneously, alleviate the work difficulty of medical worker.
