Abstract
The utility model relates to the technological improvement of a percutaneous puncturing biopsy needle, particularly a multipurpose coaxial trocar for skin puncture, biopsy and treatment. The utility model is composed of a trocar and a main body; the trocar is a hollow drum-shaped body; one end of the trocar is connected with a needle holder; two symmetrical denticles are arranged on the wall of the other end of the trocar; the main body is composed of a needle suction device, a needle core, etc. The utility model which can relieve the labour intensity and the X irradiation of doctors has the advantages of simple structure, low cost, rapid operation, less pain of patients and less complication. Once puncture operation can achieve tissue biopsy, liquid pumping, medicine injection and needle holes plugging.
Description
This utility model is the technological transformation to the percutaneous transthoracic needle biopsy needle set, and its name is called the percutaneous transthoracic needle biopsy treatment and uses coaxial trocar more.
In existing percutaneous puncture biopsy technology, if once getting puncture unsuccessful can the repetition more once of drawing materials, no matter success or not is not punctured for the third time, the diagnosis of can only drawing materials like this, can not treat simultaneously,, not only increase patient's misery and financial burden because treatment just means puncture again, also increased doctor's work frequency and be subjected to the number of times of x-ray bombardment, patient is led to complications.
The purpose of this utility model design is to avoid above-mentioned the deficiencies in the prior art and provides a kind of percutaneous transthoracic needle biopsy treatment to use coaxial trocar more, this pin is easy to manufacture, novel structure, easy and simple to handle, can repeatedly draw materials behind this pin one-time puncture, can treat again, but also the thromboembolism pin hole prevents that medicine is excessive and prevents to lead to complications.
To achieve these goals, this utility model can adopt following measure to realize: described percutaneous transthoracic needle biopsy is treated coaxial trocar and is made up of trocar and main body, trocar is a hollow cylindrical body, one end of trocar links to each other with needle stand, two symmetric little teeth are arranged on another end wall, main body is to be formed by connecting by pin and aspirator, and aspirator is made up of aspirator tube, aspirator handle, aspirator core, and pin is the inner chamber that inserts trocar in the needle stand of trocar.When operation, trocar can be maintained static, play channeling and change trocar, reach the purpose that reduces patient's misery.
To achieve these goals, this utility model can also adopt following measure to realize: described pin is a hollow body, and needle point is taper, and the needle point sidewall has the aperture of plural diameter at 0.1-0.3mm.Coaxial trocar is used in the treatment of this kind percutaneous transthoracic needle biopsy more, insert diseased tissues and extract capsule liquid out, suitable medicine reinjects, also can draw the gelatin foam suspension, or other suppositories, on one side the dial sleeve pin injects gelatin foam on one side, prevents the excessive damage normal structure of medicine and prevents the generation of complication such as hemorrhage, pneumothorax.
To achieve these goals, this utility model can also adopt following measure to realize: described needle point is three forked, also can be inclined point shape, also can assume diamond in shape, aspirator core bottom center links to each other with a nook closing member, needle core tip inserts the inner chamber of pin, under the drive of aspirator handle, can in the inner chamber of pin, move up and down, two symmetric spill grooves are arranged on the nook closing member sidewall, needle core tip assumes diamond in shape, also can be tapered.
To achieve these goals, this utility model can also adopt following measure to realize: described trocar wall approaches the 9-11 silk, diameter has three kinds of 1.0mm, 1.5mm, 2.0mm, the trocar of every kind of diameter all has three kinds of length 100mm, 150mm, 180mm respectively, the wall of the pin corresponding with trocar is thin also to be the 9-11 silk, diameter is respectively 0.8mm, 1.0mm, every kind of diameter of three kinds of specifications of 1.1mm all has three kinds of pins that length is different, the length of pin is respectively three kinds of 115mm, 165mm, 195mm, and the length of every kind of nook closing member is all than the long 2-4mm of length of corresponding pin.
In order to be illustrated more clearly in this utility model, below in conjunction with accompanying drawing this utility model is done to illustrate further.
Accompanying drawing 1 is a structural representation of the present utility model, is embodiment 1 of the present utility model.
How embodiment 1 described percutaneous transthoracic needle biopsy treatment is made up of trocar 7 and main body with coaxial trocar, trocar 7 is hollow cylindrical body, one end of trocar 7 links to each other with needle stand 4, two symmetric little teeth 8 are arranged on another end wall, main body is to be formed by connecting by pin 5 and aspirator, aspirator is by aspirator tube 1, aspirator handle 2, aspirator core 3 is formed, pin 5 is to insert in the inner chamber of trocar 7 from 4 li of needle stands, it is three forked that needle point 9 is, aspirator core 3 bottom center link to each other with a nook closing member 6, needle core tip 10 inserts the inner chamber of pin 5, under the drive of aspirator handle 2, can in the inner chamber of pin 5, move up and down, two symmetric spill grooves are arranged on nook closing member 6 sidewalls, needle core tip 10 is tapered, thin 10 of trocar 7 walls, diameter has 1.0mm, 1.5mm, 2.0mm three kinds, the trocar 7 of every kind of diameter all has three kinds of length 100mm respectively, 150mm, 180mm, the wall of pin 5 is thin also to be 10, diameter is respectively 0.8mm, 1.0mm, 1.1mm three kinds of specifications, every kind of diameter all has three kinds of pins 5 that length is different, and the length of pin 5 is respectively 115mm, 165mm, the length of three kinds of every kind of nook closing members of 195mm is all than the long 2-4mm of length of corresponding pin.
Accompanying drawing 2 is another structural representation of the present utility model, is embodiment 2 of the present utility model.
The many differences with coaxial trocar and embodiment 1 of embodiment 2 described percutaneous transthoracic needle biopsy treatments are that pin 5 does not all have nook closing member 6, pin 5 is a hollow body, needle point 9 is taper, sidewall has the aperture 13 of two above diameters at 0.1-0.3mm, there are two symmetrical handles 12 aspirator tube 1 outer wall upper end, aspirator handle 2 is umbrella, and umbrella handle links to each other with the aspirator core, and the umbrella crown diameter is smaller or equal to the diameter of aspirator tube.
