Description
Technical field
This utility model relates to technical field of medical instruments, especially modified model fine-needle aspiration of thyroid nodules pin.
Background technology
Thyroid fine needle aspiration biopsy has been defined as the very high diagnostic method of accuracy now, the conventional first step being used for Tubercle thyroid diagnostic procedure.Epidemiological study display Tubercle thyroid is clinical very common, and investigation display, the overwhelming majority's (96%) patient in patient looks into diagnosis of thyroid nodules with fine needle aspiration cell biopsy.Therefore, fine needle aspiration cell biopsy is looked into the importance had in thyroid inspection and is had some idea of.
Still there are many shortcomings and deficiencies in current paracentesis, is mainly manifested in:
(1) puncture needle and empty needle contact position are direct-connected, when puncturing sometimes because angle problem causes inconvenience.
(2) when aspirating empty needle, operation place and puncture place, at a distance of too far away, not easily fixed and are easily caused error.
(3) puncture needle only has needle point to have space, and during suction, cell quantity is few; Tuberosity edge cytologic diagnosis rate is high, but easily misses during puncture.
(4) if smear puncture thing is very few when puncturing, not easily release when empty needle is released.
Described in upper, we have done a series of improvement to make up above-mentioned defect and deficiency to paracentetic apparatus.
Utility model content
The purpose of this utility model provides modified model fine-needle aspiration of thyroid nodules pin to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: modified model fine-needle aspiration of thyroid nodules pin, comprise piercing needle and suction shell, described piercing needle is provided with linking flexible pipe, described linking flexible pipe is linked together by movable linking axle and suction shell, described suction shell is provided with and takes out pressure handle, described taking out bottom pressure handle is provided with and takes out depression bar, described in take out pressure handle and link together with suction shell by taking out depression bar, be provided with gear handle bottom described suction shell.
Be provided with suction capsule in described suction shell, described suction capsule one end is provided with fixing linking axle, and the suction capsule other end is provided with sucker rod, and described suction capsule is linked together by sucker rod and suction handle.
Described piercing needle end is provided with nook closing member, and described piercing needle is provided with pin hole, and described piercing needle top is provided with and is connected flexible pipe and nook closing member shell, and described nook closing member shell is provided with pull handle.
The beneficial effect that this utility model has is:
This utility model reasonable in design, be easy to grasp, suction is convenient, and little to tissue injury during puncture, the cell of extraction comprises in extensive range, ensure that the correctness of puncture diagnosis, improves the efficiency of medical care precess.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of this utility model piercing needle.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-2, this utility model is described below.
As shown in Figure 1-2, this utility model comprises piercing needle 5 and suction shell 1, described piercing needle 5 is provided with and is connected flexible pipe 10, described linking flexible pipe 10 is linked together by movable linking axle 15 and suction shell 1, described suction shell 1 is provided with and takes out pressure handle 4, described taking out bottom pressure handle 4 is provided with and takes out depression bar 3, described in take out pressure handle 4 and link together with suction shell 1 by taking out depression bar 3, be provided with gear handle 7 bottom described suction shell 1; Be provided with suction capsule 2 in described suction shell 1, described suction capsule 2 one end is provided with fixing linking axle 6, and suction capsule 2 other end is provided with sucker rod 9, and described suction capsule 2 is linked together by sucker rod 9 and suction handle 8; Described piercing needle 5 end is provided with nook closing member 11, and described piercing needle 5 is provided with pin hole 12, and described piercing needle 5 top is provided with and is connected flexible pipe 10 and nook closing member shell 13, and described nook closing member shell 13 is provided with pull handle 14.
When carrying out thyroid fine needle aspiration biopsy, piercing needle 5 can rotate by being connected flexible pipe 10 with suction shell 1, ensure that suction is convenient, the nook closing member 11 that piercing needle 5 end is arranged, the damage to tissue can be alleviated when puncturing, when piercing needle 5 puncture puts in place, extract nook closing member 11 out, it is more when the pin hole 12 that piercing needle 5 is arranged makes suction of cells, tuberosity edge omits chance and reduces, and the suction capsule 2 that can hold 20ml in suction shell 1 can take out pressure handle 4 by pressing, suction capsule 2 is in and takes out pressure condition, suction is larger, is easy to grasp.
