Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of biopsy needle.
Background technology
Thoracic cavity or seroperitoneum are clinically to see disease, regular incidence more, because of its cause of disease is various, is difficult to diagnosis fast and accurately, and then influences follow-up treatment, cause economic and healthy loss for patient and family members thereof, even cause delay, the deterioration of the state of an illness.At present routine clinical etiological diagnosis is mainly relied on through hydrothorax routine biochemistry, X line and CT, hydrothorax and phlegm cytology checking, fiberoptic bronchoscopy etc., can assist to make etiological diagnosis for most of patient, but still have the part patient not make a definite diagnosis, also often run into this type of patient clinically, be difficult to determine its cause of disease, according to the literature greatly about 10%～20%.
That biopsy of pleura has is easy, quick, the patient is easy to advantages such as acceptance, can effectively improve the diagnosis of the hydrothorax cause of disease.But existing biopsy of pleura also exists many shortcomings and limitation: during hydrothorax because the pleura pathological changes is not a uniformity; pathological changes is confined to a certain position of pleura or kitchen range distribution more; biopsy of pleura carries out under non-direct-view; blindness is big; clinical height suspects that pernicious hydrothorax is not to fill the air distribution on pleura; need sometimes different parts repeatedly biopsy just can obtain positive findings; once the amount of drawing materials is less for traditional biopsy of pleura pin; also limited accuracy; false negative rate can reach more than 40%; sometimes even need repeatedly draw materials, and causes health and economic loss to the patient.The tradition biopsy needle needs deeplyer because of inserting needle, and the hydrothorax amount may be damaged lung tissue after a little while, and the degree of depth of drawing materials can not control, and can only also cause damage easily by feel and patient's experience.
The method that present stage obtains the peritoneal tissues specimen has: laparotomy ventrotomy detect with peritoneoscope under draw materials, for these two technology, the patient all will bear the risk of anesthesia and operation, unsuitable popularization and application; Ascites cells is learned and is checked that positive rate is lower; Traditional hook-type pin peritoneal biopsy, the tissue of drawing materials is few, and blindness is big, and diagnostic accuracy is not high, complication such as damages, hemorrhage easily yet.On the other hand, the peritoneopathy thickening is thin to differ, and what have is very thin, and puncture easily penetrates; The peritoneopathy displacement that has is in the internal organs deep, puncture difficult through.So existing peritoneal biopsy pin is difficult to guarantee accurately to be punctured to peritoneal tissues safely, can not guarantee that the peritoneal tissues specimen amount is more than enough, the internal organs around not being damaged to again are as intestinal tube or the like.
At above-mentioned deficiency, need to explore a kind of new biopsy needle, make it on the basis that keeps original function, improve and overcome above-mentioned shortcoming.
Summary of the invention
In view of this, the invention provides a kind of biopsy needle, can find the accurate position of pathological tissues, increase the sampling amount of pathological tissues, the accidental injury to surrounding organ is also avoided in the damage that avoiding repeatedly punctures brings simultaneously, has guaranteed the safety of puncture.
The objective of the invention is to be achieved through the following technical solutions: a kind of biopsy needle comprises needle tubing, temperature sensing device and sampler;
Described needle tubing has through hole vertically near on the pin wall of needle point one end, along the circumferential direction also is provided with an annular groove near on the needle tubing wall of needle tip;
Described temperature sensing device comprises temperature inductor, temperature inductor control stick and is connected temperature inductor and the connecting rod of temperature inductor control stick, the middle part of temperature inductor is articulated on the needle tubing wall of via top and forms lever construction, temperature inductor one end is connected with the temperature sense probe, the other end is articulated in the upper end of connecting rod, the lower end of connecting rod is articulated in the upper end of temperature inductor control stick, and the lower end of temperature inductor control stick connects temperature indicator;
Described sampler comprises sampler barrel, sampling cutter and sampling cutter control stick, the sampler barrel vertical fixing is arranged on the temperature inductor, the open end of sampler barrel was concordant with annular groove when temperature inductor was unfolded, the sampling cutter is crescent and is positioned at annular groove, sampling cutter control stick is being arranged in the needle tubing around the mode single-degree-of-freedom that its axis rotates, sampling cutter control stick one end is fixedlyed connected with the handle of a knife of sampling cutter, and the other end is fixedly connected with rotary knob.
Further, described through hole, temperature sensing device and sampler are a plurality of and uniform distribution along the circumferential direction;
Further, described biopsy needle tail end is provided with the control stick fixed cap;
Further, the needle point of described biopsy needle is with can be along being placed in the needle tubing in the axially movable mode of needle tubing, also be provided with the needle point control stick in the needle tubing vertically, the needle point control stick is fixedlyed connected with needle point, the needle point control stick fixing hole of control stick fixed cap is provided with female thread, and the needle point control stick is provided with the external screw thread that matches with female thread.
The invention has the beneficial effects as follows: biopsy needle of the present invention is provided with temperature sensor, blood flow changes owing to can take place at the human lesion position, the temperature different with normal structure can appear, when the probe detection of temperature sensor behind pathological tissues, display by temperature sensor shows, to show lesion locations such as accurately having found tumor or inflammation, can accurately take a sample by the sampler of this biopsy needle; The present invention is provided with sampler specially, because adopting the sampler barrel of larger volume takes a sample, the tissue specimen amount that more traditional sampling method obtains is big, it is many to draw materials, and is convenient to obtain better positive findings, avoided because of the amount damage that causes to the patient of repeated puncture less; Biopsy needle of the present invention also is provided with the needle point of scalable adjusting, in the needle tubing of can immediately needle point being withdrawn after penetrating, has avoided may causing damage to internal organs such as intestinal tubes in sampling process, has improved the safety of puncture sampling greatly; Therefore biopsy needle of the present invention is easy to operate, and wound is little, draws materials more targetedly, improves diagnosis, has improved the safety of puncture sampling simultaneously greatly.
