Description
Technical field
The present invention relates to medical instruments fields, more particularly, to a kind of novel tissue sample sampler.
Background technique
Female mammary gland is made of skin, fibr tissue, corpus mamma and fat, and breast cancer is occurred on mammary gland gland
The malignant tumour of skin tissue is the major malignant tumor for endangering WomanHealth.Global breast cancer incidence is from the 1970s
End starts in rising trend always.8, U.S. women just has 1 people in life and suffers from breast cancer.Though China is not the height of breast cancer
Hair country, but still allow of no optimist, its disease incidence is in rise year by year trend, the growth rate of breast cancer incidence in recent years in China
It is higher by high-incidence national 1~2 percentage point, significantly higher with the death rate in coastal several cities, the death rate in city is higher than rural area.
It is shown according to National Cancer Center and prevention and control of diseases office, the Ministry of Public Health pathogenesis of breast carcinoma data in 2009 announced in 2012: the whole nation
Tumour registration area breast cancer incidence occupies the 1st of female malignant, and (rough and careless) whole nation of female mammary gland cancer morbidity is closed
42.55/10 ten thousand are calculated as, city is 51.91/10 ten thousand, and rural area is 23.12/10 ten thousand.
Treatment for breast cancer, doctor can use as one sees fit operation, put according to tumour by stages with the physical condition of patient
The multiple means such as treatment, chemotherapy, endocrine therapy, Biological target therapy and traditional Chinese medicine adjuvant treatment.In the past 20 years, it is with operation
The heart, chemotherapy, radiotherapy, the multidisciplinary synthesis treatment mode that endocrine therapy is auxiliary obtain significant progress, make answering for breast cancer
Hair and the death rate significantly reduce.Although clinical research has been achieved for biggish progress, recurrence and metastasis rate is still very
It is high.Patient is after treating and restoring a period of time, it is also necessary to be checked, to determine patients surgery therapeutic effect.It is existing
Check mode be usually: cut the mammary gland of patient and --- cut portion of tissue sample --- titanium pinching blood --- graticule and determine sampling
Position --- line suture opening, but this sampling mode sample time is more long, and needs multiple people's compounding practices.In addition, existing
Sampling be mostly the sample for once taking a position, the selection representativeness of sample may not enough, testing result inaccuracy, to more
Sub-sampling, then process is relatively complicated and time-consuming long.
Summary of the invention
The present invention is directed to overcome at least one defect of the above-mentioned prior art, a kind of novel tissue sample dress is provided
It sets, for solving, existing mammary gland check sampling mode is inconvenient, the operating time is relatively long and can not take multiple samples simultaneously
Problem.
The technical solution adopted by the present invention is that:
A kind of novel tissue sample sampler is sampled including mounting disc, several tissue samples being mounted in mounting disc
Device and for pulling the pull rod of tissue sample sampler simultaneously, the single tissue sample sampler include shell,
For accommodating the cavity of tissue sample, the sliding block being arranged on shell, the tracheae communicated with cavity, being equipped in the sliding block can hold
Receive the cavity of blade and needle, the blade and needle pass through spring and the top of sliding block connects, and are additionally provided with the first opening on shell
With the second opening, the tissue sample sampler is additionally provided with titanium folder at port, and the titanium folder is located in titanium clamp pincers, the titanium
Clamp is connect by connecting rod with sliding block, the block for tightening cavity port is additionally provided on the shell, the connecting rod is passed through
The first opening is worn, the blade and needle pass sequentially through the second opening in the motion process of sliding block and enter cavity；Tissue sample takes
Mounting disc is run through in one end that sampling device is equipped with titanium folder；The sliding block is connect with pull rod.
Novel tissue sample sampler of the present invention can be used in extracting multiple tissue samples simultaneously, wherein tissue
Sample sampler is for taking tissue sample, and mounting disc is for installing several tissue sample samplers.In operation,
Tracheae be connected to extraneous air extractor first, by the port of novel tissue sample sampler titanium folder side be aligned to
Tissue site is sampled, pumping is inhaled into tissue sample in cavity by suction function, pulls pull rod, and sliding block sliding is located at and slides
Needle inside block passes through the second opening when reaching the second aperture position under the action of the spring and enters cavity, and needle can then inject sample
It is interior.In continuing sliding process, the blade inside sliding block can also arrive in succession up to the second aperture position, equally in spring sliding block
Under the action of enter cavity in, since tissue sample one end is worn by needle, one end is connected with human body or animal body, and there are one at both ends
Determine pulling force, blade can cut off rapidly tissue sample after entering cavity.Meanwhile titanium during sliding block sliding, at port
Clamp can then follow the sliding of sliding block and move, gradually close to for tightening cavity end due to being connected by connecting rod with sliding block
The block of mouth, titanium clamp pincers and titanium folder tightening, titanium clamp tissue sample, play anastalsis under the action of block.Sliding block after
In continuous sliding process, titanium clamp pincers are due to moving away from block again, and pliers is again gradually in the case where not by block squeezing action power
It opens, and titanium folder is not moved due to grip tissue sample followed by titanium clamp pincers, after blade cuts off tissue sample, tissue
Sample a part rests on needle, and a part returns back in human body or animal body, and titanium folder is with returning back to human body or animal body
Tissue sample rests in human body or animal body.Novel tissue sample sampler of the present invention can by a doctor or
Person nurse individually completes tissue sample sampling, only by an operator can be completed at the same time multiple tissue samples extract, shearing,
Hemostasis, sampling operation is easy, continuous quick.
In one of the embodiments, the pull rod include for blocking the fixture block of sliding block, the gripping for pulling fixture block
Portion and the interconnecting piece for connecting grip part and fixture block.Since fixture block is seized sliding block, fixture block is connect by interconnecting piece with grip part,
In actually behaviour, operator, which holds grip part, can pull sliding block, realize to the extraction of tissue sample, shearing, stop blooding and take
Sample operation.Since sliding block is connect with pull rod, by pulling a pull rod that can pull all sliding blocks simultaneously, tissue sample is completed
Sampling.
