Description
The present invention relates to a kind of medically for obtaining in the human or animal body biopsy sampling method and Protractor than the deep regional biological tissue.
Medically, for determining the character of human body or animal in-vivo tumour, to carry out direct sample to the biological tissue of tumor locus usually, and then it is carried out biopsy.In sampling process, also inequality according to the different sampling methods that adopt in the position at tumor place.As can directly adopt the mode of surgical cutting operation for the tumor sampling of human body surface, this sampling is comparatively simple.And take a sample for the hollow organ that communicates with the surface, to directly cut by means of endoscope and relevant appliance usually, so this sampling method relative complex, the utensil of use is more.
Yet, in the prior art, for in the body surface particularly the tumor than deep regional take a sample, because these position staff can not directly touch, so be forced to directly adopt surgical operation to take a sample in some occasions, this kind mode will have big wound on one's body the uke, brings very big misery not only for its body and mind, and the time also will be subjected to executing the restriction of art condition, and then increase the sampling expense in operation.
In order to solve a series of problems that surgical operation brings, but occur the utensil of the direct sample of multiple structure on the market, be referred to as puncture needle.Its structure of one type puncture needle is basic identical with existing entry needle, when sampling operation, this pin is being suffered from the biological tissue of tumor by the human body surface thorn, do circumference formula cutting among a small circle at this tissue then, the negative pressure that is produced when utilizing needle tubing outwards to spur is at last taken out the cell tissue suction that described roundlet middle part cuts down on needle point.The puncture needle of another kind of structure is that needle point is made thread-shaped, when its with the biological tissue of needle point thorn in tumor on the time, continue again to screw, make it have portion of tissue to enter in the screw thread, and then this part tissue taken out.As can be seen, though described puncture needle structure is simple, it is comparatively convenient to use, less with the biological tissue that this kind pin is taken out, and makes its pathologic finding accuracy rate in biopsy relatively low, easily causes false negative result; In addition, adopt this kind pin biopsy sampling, because this pin cuts in sampling process or screws in the process, the cell that breaks away from tissue also is detained in vivo, and the stroke of in body, extracting pin, because human body has certain contractility, cell tissue on the needle point is freely come off in motor process, so the generation of above-mentioned situation causes the malignant cell implantation metastasis probably, brings adverse consequences to the operation receiveing person.
Task of the present invention provides a kind of biopsy sampling method and Protractor, this method and apparatus only need adopt very little wound just can be easily safely predetermined amounts take out the active somatic cell sample of deep regional in the human or animal body.
For finishing above-mentioned task, biopsy sampling method proposed by the invention may further comprise the steps substantially:
At first the need sampling point is carried out disinfection and local anesthesia, form the open passage that diameter is as far as possible little to the body between the biological tissue at skin surface again;
Next adopts the gripping parts directly to obtain the biopsy cell of scheduled volume through described passage, and then this cell is carried out biopsy.
So-called open passage promptly is with sharp thing wound of break-through between surface and tumor, with supporter this wound is supported formed passage then.
Protractor proposed by the invention has one and has the conduit of guiding syringe needle and the clamp that can extend into pre-determined amount biological tissue in taking-up human body in this conduit or the animal body when the guiding syringe needle takes off once more.Conduit is two discrete parts with the guiding syringe needle, two unit constructions can be used as puncture needle together the time and use, when this acupuncture promptly feels hard to the precalculated position, to guide syringe needle takes off, and conduit stayed put, and then clamp is sent in the conduit, and tumor cell tissue's predetermined amounts is taken out by clamp.
Described conduit comprises the rod member of a hollow, and an end of this rod member is provided with socket piece; Described guiding syringe needle has a long pole that can extend in the described conduit, and an end of this rod member is tapered rib dimension shape, and the other end is provided with the bellmouth spare that is complementary with the conduit socket piece.
Described supravasal socket piece has female thread, and the bellmouth spare on the guiding syringe needle is provided with the external screw thread that is complementary with described female thread.
Described clamp far-end is provided with the pivoted jaw by axis limit, and near-end is provided with the control member that can make this jaw make opening and closing movement.
Control member on the described clamp has one and has the handheld component of axial groove and can put into the stick of hollow rod member and described axial groove, and is arranged on the clutch that the makes described jaw action stick front end and that be controlled by this stick.This clutch has a trace that is used to limit the pivot of described jaw and is installed in another extended end of jaw.
Biopsy sampling method proposed by the invention is to make a little open passage earlier, utilize this passage to carry out sampling operation then, in operating process because of with tumor beyond human body do not contact, so, do not revealing under the wound situation of wanting big, just can take out the cell tissue of scheduled volume, also can avoid adverse consequencess such as transplantation metastasis simultaneously; In addition, this Protractor has adopted one the clamp that can extend in the conduit, and the anterior jaw of this clamp can be measured out tumor cell tissue on demand almost closedly, so, this installs compared with prior art structure and uncomplicated, operates also very convenient, and safe and reliable.
