Technical Field
The utility model relates to a medical apparatus technical field of oncology, concretely relates to clinical puncture sampler that uses of oncology.
Background
The tumor is an abnormal lesion formed by clonal abnormal hyperplasia caused by that a certain cell of a local tissue loses normal regulation and control on the growth of the local tissue on the gene level under the action of various carcinogenic factors of an organism, but the tumor is divided into benign tumor and malignant tumor, and the pathological analysis of the tumor needs to sample and analyze the interior of the tumor.
At present, the tumor biopsy sampling is carried out on the patient clinically, the sampler is generally used for sampling, but the needle cavity of the traditional sampler is narrow, the sampling amount is small at one time, the requirement of detection can be met only by inserting the sampling in the patient body for multiple times, and the injury to the patient is large.
SUMMERY OF THE UTILITY MODEL
To the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a puncture sampler for clinical oncology, which effectively solves the problem of less sampling amount of the prior sampler.
The technical scheme of its solution is, the utility model discloses a from top to bottom axial and terminal surface are the cylinder on inclined plane, and the coaxial detachable fixed block that is equipped with in cylinder upper end, coaxial rotation are connected with the pivot that the lower extreme is located the cylinder in the fixed block, and the pivot lower extreme is coaxial to be equipped with the spiral sword, and the sample inlet that is located the spiral sword right side is seted up to the cylinder downside, and the side is equipped with the cutting knife of direction from top to bottom on the sample inlet.
Compared with the prior art, the beneficial effects of the utility model are that: set up spiral sword and introduction port and cutting knife cooperation, the knob drives the spiral sword through the pivot and constantly rotates, constantly cuts tumor tissue, can once only gather a large amount of tumor samples, avoids pricking patient's health many times, has reduced the injury to the patient, has reduced the sample degree of difficulty, has improved doctor's work efficiency, this simple structure, and convenient operation conceives the novelty, and the practicality is strong.

Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
By giving of fig. 1 to 4, including upper and lower axial and down the terminal surface for the cylinder 1 of inclined plane, the coaxial detachable fixed block 2 that is equipped with in 1 upper end of cylinder, the coaxial pivot 3 that is connected with the lower extreme and is located cylinder 1 of coaxial rotation in the fixed block 2, the coaxial spiral sword 4 that is equipped with of 3 lower extremes of pivot, the sample inlet 5 that is located spiral sword 4 right side is seted up to 1 downside of cylinder, the side is equipped with the cutting knife 6 of direction from top to bottom on the sample inlet 5.
In order to rotate the rotating shaft 3, a knob 7 is coaxially arranged at the upper end of the rotating shaft 3.
For the convenience of dismantling fixed block 2, 1 upside of cylinder seted up about the draw-in groove 8 that link up, seted up in fixed block 2 and lie in its right side and the fixed slot 9 of upper and lower direction, fixed slot 9 left surface is connected with the push pedal 11 of upper and lower direction through spring leaf 10, push pedal 11 right-hand member is equipped with stopper 12 that can insert in draw-in groove 8, fixed slot 9 right-hand member is equipped with and is located stopper 12 directly over and the right-hand member runs through ejector pad 13 of fixed block 2, ejector pad 13 and 2 sliding connection of fixed block.
In order to limit the limiting block 12, the upper end of the needle cylinder 1 is provided with a limiting groove 14 which is communicated with the clamping groove 8 and has a leftward opening.
In order to facilitate holding, a handle 15 which is positioned below the limit groove 14 and in the front-back direction is arranged on the outer edge surface of the needle cylinder 1.
In order to facilitate the observation of the depth of the device penetrating into the human body, the outer edge surface of the needle cylinder 1 is provided with a plurality of scales 16 which are uniformly distributed along the vertical direction.
When the utility model is used, the spiral knife 4 is inserted into the needle cylinder 1 by holding the fixing block 2, the push block 13 is pushed leftwards at the same time, the push block 13 drives the push plate 11 to move leftwards and extrude the spring leaf 10, the push plate 11 drives the stopper 12 to move leftwards, so that the right end face of the stopper 12 is contacted with the right side face of the limit groove 14, when the lower end face of the stopper 12 is contacted with the lower side face of the clamping groove 8, the push block 13 is loosened, the push plate 11 moves rightwards under the action of the spring leaf 10, the push plate 11 drives the stopper 12 to move rightwards and is inserted into the clamping groove 8, at the moment, the fixing block 2 is fixed in;
one hand grips the handle 15, the thumb, the index finger and the middle finger of the other hand pinch the upper side of the needle cylinder 1, and the device is in a vertical state according to the requirements of patients;
because the lower end surface of the needle cylinder 1 is an inclined surface, the needle cylinder 1 can be penetrated into a human body, the scale 16 which is parallel to the skin is observed when the needle cylinder 1 is penetrated into the human body, the reading of the scale 16 is the depth of the needle cylinder 1 penetrated into the human body, and when the reading of the scale 16 is consistent with the measured depth of the tumor according to the position of the tumor detected before sampling, the needle cylinder 1 is stopped being penetrated into the body of a patient;
the knob 7 is rotated anticlockwise, the knob 7 synchronously drives the spiral knife 4 to rotate anticlockwise through the rotating shaft 3, and as the tumor tissue is extruded into the needle cylinder 1 from the sample inlet 5, the tumor tissue in the needle cylinder 1 is divided by the cutting knife 6 while the spiral knife 4 rotates, and moves upwards along with the rotation of the spiral knife 4, the knob 7 is continuously rotated, and tumor samples can be continuously collected;
after sampling, extract this device from the patient internal, promote ejector pad 13 left, ejector pad 13 drives push pedal 11 and moves and extrude spring leaf 10 left, and push pedal 11 drives stopper 12 and moves left, and stopper 12 is taken out from draw-in groove 8, and upward movement fixed block 2, fixed block 2 drive spiral sword 4 upward movement and take out from cylinder 1 through pivot 3, put into the container with the sample on the spiral sword 4, and the sample is accomplished.
Compared with the prior art, the beneficial effects of the utility model are that: set up spiral sword and introduction port and cutting knife cooperation, the knob drives the spiral sword through the pivot and constantly rotates, constantly cuts tumor tissue, can once only gather a large amount of tumor samples, avoids pricking patient's health many times, has reduced the injury to the patient, has reduced the sample degree of difficulty, has improved doctor's work efficiency, this simple structure, and convenient operation conceives the novelty, and the practicality is strong.
