Description
Technical field
It is specially a kind of to spray with sampling the gear shifting type cervical biopsy being combined the present invention relates to technical field of medical instruments
Pincers.
Background technology
Biopsy is also known as biopsy, refers to the demand that should be diagnosed, treat, and takes or wears from patient's body to cut, clamp
The modes such as thorn take out pathological tissues, carry out the technology of pathological examination.It is various types of especially for what is formed in body
, it is necessary to identify the type of tumour by cytoscopy when tumour carries out Precise Diagnosis treatment, to determine to implement the medicine for the treatment of
Thing and method.
Cervical carcinoma is most common gynecologic malignant tumor, with people's living environment and the change of habits and customs, in recent years
It, which is fallen ill, the trend of rejuvenation, cervical cytology examination it is commonly used, enable cervical carcinoma and precancerous lesion early detection
And treatment, the morbidity and mortality of cervical carcinoma have been decreased obviously.Cervical cell screening needs to carry out biopsy sampling.Uterine neck is lived
Inspection pincers can cause sample point bleeding when clamping tissue sample, and traditional way is will be after sampling tissue taking-up, then to blutpunkte
Hemostasis processing is carried out, efficiency is low, and effect is poor.
Notification number disclosed in 9 days March in 2016 is the U of CN 205072916 patent of invention, discloses a kind of band spray work(
The Cerver biopsy tongs of energy, it is provided with decoction conveyor chamber by being embedded in atomizer in the front end of binding clip inside the bottom wall of claw beam
Room, the rear end of claw beam are connected by syringe interface with syringe.Although bleeding part is carried out immediately when can realize biopsy
Spray hemostasis, but inconvenience is operated, after clamping tissue, a direction needs to stablize biopsy forceps, on the other hand needs to operate note again
Emitter is sprayed, a hand-hold pincers, is injected on the other hand, easily causes biopsy forceps shakiness, in addition, the decoction of spray blood hemostasis is easily to taking
Sample pollutes, and reduces the accuracy of inspection.
Therefore, it is necessary to which one kind is easy to operate, stability is good, is stopped blooding while can realizing sampling, and can prevents from taking
Sample tissue is by the Cerver biopsy tongs of liquid medicine contamination.
The content of the invention
It is an object of the invention to provide a kind of gear shifting type Cerver biopsy tongs, can effectively realize while sampling, to taking
Sample position sprinkling decoction carry out disinfection sterilizing or hemostasis processing, and avoid sample tissue by liquid medicine contamination.
To achieve the above object, the present invention provides following technical scheme：A kind of gear shifting type Cerver biopsy tongs, including driving hand
Handle, grip part and claw beam, the claw beam include the channel bar of bottom and the mast on top, and the mast front end is connected with storage tube,

Not to it is corresponding when realize mast and piston rod simultaneously advanced, when through hole and mast to it is corresponding when realize to piston rod propulsion administration,
When through hole and piston rod to it is corresponding when realize that the propulsion to mast samples.
2nd, driving handle realizes driving gear shift thumb wheel anterior-posterior translation in grip part by drive rod axis, and then by changing
Shelves thumb wheel promotes mast and/or piston rod to travel forward, and the tubular structure of channel bar front end is engaged with the storage tube of mast front end,
Shear action is formed using its marginal portion, by sampling tissue shearing, and under the continuation progradation of mast, tissue will be sampled
It is pressed into storage tube, after sampling tissue enters storage tube, in the presence of valve is closed, closure closing, effectively reduces and avoid
When spraying decoction anti-inflammation hemostasia to sampling point, liquid medicine contamination bending tissue.When sampling tissue enters storage tube, gear shift thumb wheel pushes away
Piston bar releases the decoction in piston cylinder, and reaches outlet injection along circulation duct, and carry out disinfection sterilizing to sampling point
Or hemostasis processing.Or mast or piston rod are individually promoted, realize individually sampling and individually sprinkling medicine.
3rd, mast front end is flexibly connected storage tube, is convenient for changing, and storage tube is disposable, safe and healthy, and to taking
Sample tissue is effectively protected, and also avoids causing other pollutants to adhere to when biopsy forceps takes out from patient's body.
4th, spring is connected between fixed handle and the finger ring of flexible handle lower end, conveniently after sampling, in the effect of spring
Under, gear shift thumb wheel automatic returning, mast and/or piston rod are withdrawn in the presence of the spring each set, simplicity, are saved trouble.
5th, the present invention is simple in construction, easy to operate, and sampling, spray are carried out or individually carried out simultaneously, both hands behaviour
Make, hold grip part on the other hand, operate driving handle on the other hand, stability is good.
