Abstract
The utility model relates to the technical field of medical puncture technology, in particular to a multipurpose medical puncture needle, which comprises an opening needle seat (3), a needle body (3) and a needle tip (1), wherein the needle body (2) and the needle tip (1) are connected to the needle seat (3). The multipurpose medical puncture needle is characterized in that the end face of the needle tip is a closed structure or a through cavity structure or distributed with a plurality of multiform through holes (4), a plurality of multiform holes (5) are distributed on the peripheral wall of the end of the needle body (2) extending from the needle tip (1) to the needle seat (3), and the multiform through holes (4) and the multiform holes (5) are communicated with a needle cavity. The multipurpose medical puncture needle can avoid blocking the needle cavity when puncturing tissues such as skin and muscle, avoid multiple puncture and reduce suffering of patients. Besides, the puncture needle is simple in structure, large and uniform in medicine/liquid injection range and convenient in operation.
Description
Technical field
This utility model relates to medical apparatus and instruments puncture technique field, the many medical puncture needles of particularly a kind of multipotency.
Background technology
The puncture injection technology is widely used in clinical, but in fine and close muscle or tumor tissues, the puncture needle of general syringe needle single hole, the scope of injection is little, and resistance is big, and fluid injection is inhomogeneous.The thick puncture needle of needle body is when operation, and tissue can stop up the pin chamber, can influence injection and cause patient more painful.
Summary of the invention
The purpose of this utility model provides the many medical puncture needles of a kind of multipotency, and this puncture needle has solved that tissue can stop up pin chamber phenomenon in the clinical manipulation, the pathological tissues flushing in the puncture needle chamber easily, it is simple in structure, injection is even, and is easy to operate.
The purpose of this utility model is achieved through the following technical solutions, design the many medical puncture needles of a kind of multipotency, it comprises open needle stand and is connected the needle body and needle point on the needle stand, it is characterized in that: be full-closed structure or be cavity structure or be distributed with several multiform apertures at the needle point end face, be distributed with the multiform aperture at needle point on the needle body end perisporium that needle stand extends, several multiform apertures communicate with the pin chamber respectively.
Described several multiform apertures are the net distribution structure.
Long 5～the 30cm of described puncture needle pin.
Described needle body external diameter is 0.5～5mm.
Described needle body external form is shaped as circle, or oval, or prismatic, or square.
Described needle point 1 bevel angle is 15 °～45 °.
Described multiform hole shape is circular, or oval, or prismatic, or square, or rectangle.
Characteristics of the present utility model are: many medical puncture needles of multipotency needle point is totally-enclosed or is equipped with 1 macropore or be equipped with a plurality of multiform apertures slightly, can prevent that tissue stops up the pin chamber in the piercing process, avoids repeatedly puncturing, and alleviates patient's misery; Having a plurality of multiform apertures near on the needle body perisporium at needle point position, be the net distribution structure, when making water filling cleaning or drug-injection in treatment, flow direction is more even, and resistance is little, and scope is big; This utility model is simple in structure, and is easy to operate, by the rustless steel manufacturing, can use repeatedly after the sterilization, and cost is low.
Description of drawings
Below in conjunction with the embodiment accompanying drawing this utility model is described further.
Fig. 1 is the example structure sketch map.
Fig. 2 is that the A of Fig. 1 is to partial enlarged drawing.
Fig. 3 is that the B of Fig. 1 is to partial enlarged drawing.
Among the figure: 1, needle point; 2, the needle body; 3, needle stand; 4, multiform aperture; 5, multiform aperture.
The specific embodiment
Embodiment 1 as shown in Figure 1, this utility model passes skin, muscle etc. by needle point 1 and enters pleural space or abdominal cavity, connects needle stand 3 with asepsis injector and carries out drawing liquid, bleeds etc.The many puncture needles of multipotency comprise needle point 1, the needle body 2, needle stand 3.Many puncture needles of multipotency needle stand 3 is uncovered, needle point 1 is totally-enclosed or is distributed with several multiform small structures, near perforate or be distributed with several multiform apertures 5 relatively on the needle body perisporium at needle point 1 position, be network structure, multiform aperture 4 and multiform aperture 5 be shaped as circle, or oval, or prismatic, or square, or rectangle.Multiform aperture 4 and multiform aperture 5 communicate with the pin chamber respectively, and needle stand 3 can connect syringe and aspirate and inject.Long 5～the 30cm of many puncture needles of multipotency pin, the needle body 2 external diameters are 0.5～5mm, and the needle body 2 profiles are multiple shape, and the needle body 2 external forms are shaped as circle, or oval, or prismatic, or square.Needle point 1 bevel angle is 15 °～45 °.Present embodiment is by relatively perforate or be distributed with several multiform apertures 5 and communicate with the pin chamber on the needle body 2 front end circumferential wall, and needle stand 3 connection syringes aspirate.
The structure of embodiment 2 is substantially the same manner as Example 1, as architecture advances to embodiment 1, needle point 1 is the cavity structure, near perforate or be distributed with multiform aperture 5 relatively on the needle body perisporium at needle point 1 position, be the net distribution structure, multiform aperture 4 and multiform aperture 5 communicate with the pin chamber respectively, and needle stand 3 can connect syringe and aspirate.Present embodiment by the cavity body needle point 1 and the needle body 2 perisporiums on the multiform aperture 5 that distributes communicate with the pin chamber, needle stand 3 connects syringes and aspirates.The puncture needle cavity of this structure is big, more easy to operate.
Embodiment 3 is as the architecture advances to embodiment 1, be on the end face of needle point 1, to be equipped with a plurality of multiform apertures 4, near perforate or be distributed with multiform aperture 5 relatively on the needle body 2 walls at needle point 1 position, be network structure, multiform aperture 4 and multiform aperture 5 communicate with the pin chamber respectively, and needle stand 3 can connect syringe and aspirate.Present embodiment is by relative perforate on needle point 1 and the needle body 2 perisporiums or be distributed with multiform aperture 5 and communicate with the pin chamber, and needle stand 3 connects syringes and aspirates.The suction face of the puncture needle of this structure is network structure, is the optimum structure mode.It is easy to operate, makes the site of puncture flow direction of water filling cleaning or drug-injection in treatment more even.
During concrete operations, according to diseased region, character, get the suitable position of patient, the anesthesia of sterilization local skin checks whether the many puncture needles of multipotency are unimpeded, under the B ultrasonic guiding, left hand is site of puncture skin fixedly, and the right hand is held the many lancet puncture of multipotency, when determining to enter pleural space, abdominal cavity, or other is connected to base 3 positions with syringe when needing the position of puncture injection, aspirates or injects the medicinal liquid treatment, when puncture finishes the many puncture needles of multipotency are extracted, sterile gauze covers.
