Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a biopsy needle.
Background
Biopsy, which is called "biopsy," also called surgical pathology examination for short, refers to a technique of taking out diseased tissue from a patient's body by cutting, clamping, puncturing, or the like, and performing pathology examination, as required for diagnosis and treatment. The morphological examination of living tissues is an important method for disease diagnosis, and the pathological examination of living tissues is mainly used for the identification of tumor and non-tumor diseases, benign and malignant tumors, the judgment of the degree and range of growth, invasion and metastasis of malignant tumors, the observation of the development degree or treatment response of diseases, and the like. According to different instruments and methods applied in the pathological examination of the living tissues, the pathological examination of the living tissues is cut, namely, a part of pathological changes and adjacent normal tissues are cut; the pathological examination of excised living tissues is to excise all lesions for inspection; the pathological examination of the living tissue of the endoscope is to take a little pathological tissue by an endoscope forceps; the needle aspiration biopsy for pathological examination is to aspirate a small amount of tissue with a puncture needle, scrape, drill, etc., then select the biopsy tissue to prepare paraffin sections, and perform histological examination under a microscope, if necessary, by means of an electron microscope or immunohistochemistry. It is the most important part of the diagnosis pathology, and it can make clear histopathological diagnosis for most of the examined cases, and it is used as the final diagnosis in clinic.
With the development of clinical diagnosis and treatment technology, histopathological diagnosis has become an important diagnostic tool. In the diagnosis of kidney diseases, kidney biopsy has become a routine examination item in nephrology, which can provide reliable pathological diagnosis basis for early diagnosis of kidney diseases and establishment of complete treatment plan, but for some difficult and rare cases, the diagnosis needs to be assisted by histochemistry, immunohistochemistry, electron microscopy or molecular biology and other technologies on the basis of the routine examination.
The conventional procedure for biopsy is: the patient takes the prone position, and the kidney is fixed relatively to the back side by a pillow with the thickness of about 10cm on the abdomen cushion. Generally, selecting right infrarenal essence as a puncture target, generally positioning, disinfecting skin conventionally, paving an aseptic towel, wearing aseptic gloves by an operator, disinfecting a puncture probe, using 75% ethanol as a lubricant, fixing a puncture point, performing local layer-by-layer anesthesia by using 2% lidocaine, puncturing the skin by a sharp knife, puncturing the subcutaneous part by the puncture needle, putting the puncture probe into a needle groove, measuring the distance from the skin to a renal capsule, and inserting the needle to the renal capsule. Under the ultrasonic monitoring, the depth of the needle insertion can be clearly observed, a patient is ordered to hold his breath, and the needle is quickly inserted into the kidney tissue and pulled out, so that the puncture process is completed.
The tissue biopsy needle that uses at present clinically all is the single groove, satisfy the demand of pathology detection and scientific research simultaneously for guaranteeing enough histocyte and full, need puncture twice at least, but the repeated location puncture can increase the damage and bleed the risk, and simultaneously, the repeated puncture also is difficult to the position of accurate positioning to last puncture, it is big easily to cause the pathology result difference, take place the needle track during tumor biopsy and plant, also can not satisfy the demand of scientific research simultaneously, consequently, need for one kind and need not the puncture of relocating, satisfy the scientific research demand simultaneously, the convenient double flute tissue biopsy needle of puncture.
Disclosure of Invention
In order to solve the problems that damage and bleeding risks are increased by repeated positioning puncture of the conventional clinical single-groove tissue biopsy needle, the difference of pathological results is large, and pathological detection and scientific research requirements cannot be met simultaneously, the invention provides the double-groove tissue biopsy needle.
The invention is realized by the following technical scheme:
the embodiment of the invention provides a double-groove tissue biopsy needle, which comprises a sheath tube, a sheath handle and a needle core, wherein the sheath tube is connected with the sheath handle, the needle core which is matched with the sheath tube is arranged in the sheath tube, a first groove and a second groove are arranged at the position of the needle core, which is close to a needle head, and the needle handle is arranged at one end, which is far away from the needle head, of the needle core.
In the invention, the first groove and the second groove are provided with cutting knives with opening directions opposite to the directions of the needle cores.
In the invention, the first groove and the second groove are arranged at two ends of the central axis of the needle core.
In the invention, one end of the sheath handle is provided with a cutting head according to the principle of the sheath tube.
In the invention, the outer side of the sheath tube is provided with scale marks.
The double-groove tissue biopsy needle provided by the invention has the following beneficial effects:
(1) adopt first groove and second groove double flute structure, can get two biopsy tissues simultaneously, satisfy pathological diagnosis and scientific research demand simultaneously, avoid the repeated location puncture to cause damage and the risk of bleeding.
(2) The first groove and the second groove are provided with cutting knives with opening directions opposite to the direction of the needle core, so that tissue cells of the biopsy part can be taken more quickly and accurately.
(3) The cutting head at the tail end of the sheath tube is matched with the needle core, so that the biopsy tissue can be taken out conveniently, and the risk of needle channel planting is reduced.
(4) The scale mark of sheath pipe outer wall can help accurate the control to pierce the degree of depth, and is more accurate high-efficient when surely getting the biopsy.
