The specific embodiment
For further setting forth this utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of puncture needle for minimally invasive treatment, structure, using method, feature and the effect thereof that the utility model proposes, describe in detail as after.
Embodiment one
See also shown in Figure 1ly, this utility model puncture needle for minimally invasive treatment mainly is made up of metal nook closing member 1 and soft sleeve pipe 2.
Wherein, soft sleeve pipe 2 adopts the material medical, hypo-allergenic, that soft durometer is moderate, make as special molecular structure plastics (polyethylene), thermoplastic poly chloro-ethyl formate (TPU) etc., to lower damage to tissue, strengthen its safety, indwelling property, also can add coating, to alleviate adhesion to tissue at soft sleeve pipe 2 outer surfaces.
The a plurality of side perforations 21 of soft sleeve pipe 2 anterior cross-distribution, side perforation 21 can be designed to varying number, distribution and aperture specification according to telescopic internal diameter and length, carry out personalization at position, scope and the feature of focus and select, make therapeutic process individuation more.For example: metal nook closing member 1 long 150cm-200cm, side perforation 21 distribute spacings of soft sleeve pipe 2 are 8cm, 6cm, 4cm or 2cm, the external diameter of needle tubing is designated as 20G-16G according to general international standard Gauge (G).
The afterbody of soft sleeve pipe 2 is the syringe connecting portion, can be provided with folder and close device and shutoff medicated cap.The soft sleeve pipe 2 tube walls outside also can indicate scale, so that observe, control the injection dose.
The external diameter of metal nook closing member 1 is slightly less than the internal diameter of soft sleeve pipe 2, and it can be inserted in the soft sleeve pipe 2 just; But needle body surface indexing send the pin degree of depth so that observe; Screw thread also can be carved with in nearly needle point place, to strengthen ultrasonic reflection intensity.
Preferable, the tip portion of metal nook closing member 1 leans out soft sleeve pipe 2, the slightly thin also part syringe needle of coated metal nook closing member 1 of the little receipts of soft sleeve pipe 2 front end bores, thickness, thus puncture smoothly guaranteed, and soft sleeve pipe 2 can not be subjected to displacement with metal nook closing member 1 in sending the pin process.
During use, metal nook closing member 1 is inserted in the soft sleeve pipe 2, both be convenient to this utility model puncture needle for minimally invasive treatment is sent in patient's body, also be beneficial to sending the pin process to observe, monitor.After sending the pin end of operation, metal nook closing member 1 is extracted out, soft sleeve pipe 2 is kept somewhere in patient's body, can realize one-time puncture, repeat administration.
Embodiment two
See also shown in Figure 2ly, on the basis of embodiment one structure, also can be beneficial to the indwelling position of the soft sleeve pipe 2 of iconography monitoring observation at the fixedly connected metal needle point 22 of the front end of soft sleeve pipe 2.Metal needle point 22 can be selected the not metal material of frangibility of high resilience for use, casts the shape that rhombus, domatic, vertebral body shape etc. are sharp, penetration power is strong, and in the ultrasonic effect that has multiple radiation down, it is more clear that needle point is developed.Recessed convex, inclined-plane interlock or plane mode such as join is closely carved and is closed beyond the metal needle point 22 of metal nook closing member 1 and soft sleeve pipe 2, thereby is beneficial to the puncture inserting needle.
Preferable, the connected mode of metal needle point 22 and soft sleeve pipe 2 can be shown in Fig. 3 a, 3b, 3c, the connection end of metal needle point 22 is designed to double-decker, and is provided with projection between double-decker.During connection, the front end of the soft sleeve pipe 2 of double-decker clamping of metal needle point 22, projection embeds soft sleeve pipe 2 simultaneously, can guarantee that thus metal needle point 22 is connected firmly with soft sleeve pipe 2, transition is smooth.
Embodiment three
See also shown in Figure 4ly, soft sleeve pipe 2 of the present utility model also can be the major and minor tubular construction of Y font, and the looped pipeline bifurcation is apart from being responsible for the about 3cm of tail end, and the tail end design of looped pipeline is with being responsible for, and communicates with person in charge's inner chamber.This structure puncture needle for minimally invasive treatment send the pin mode identical with embodiment one, be about to the person in charge that metal nook closing member 1 inserts soft sleeve pipe 2, can realize sending pin to observe simultaneously and monitor easily, and be injectable drug and time treatment under the situation that metal nook closing member 1 is not extracted as yet fully.
Embodiment four
On the basis of embodiment three, soft sleeve pipe 2 of the present utility model also can be designed to the double channel catheter structure, conduit 1 and conduit 2 24 connect with the mouth of pipe of the person in charge, looped pipeline respectively, and its distribution can be shown in schematic cross-section Fig. 5 a around distribution, adopt that also half bag shown in Fig. 5 b distributes etc.Conduit one 23 front ends are open, the sidewall sealing, and metal nook closing member 1 can be finished puncture by this tube chamber, and colloid styptic is through this tube injection, and delivery routes is shown in Fig. 6 a.The even cross-distribution of conduit 2 24 anterior outer walls many places side perforation, front end is convenient to injection water dissolubility hemorrhage apart from the sealing of conduit one 23 most advanced and sophisticated 0.5-1.0cm places, and the drug delivery path is shown in Fig. 6 b.
This utility model puncture needle for minimally invasive treatment can be realized one-time puncture, multiple dosing, and is easy to monitoring and send the pin process, obviously alleviates the patient suffering and reduces the treatment difficulty, and many side perforations designs make medicine even action, efficient.Be applied to both can reach thorough hemostatic purpose in the on-the-spot treatment fast of abdominal part substantial viscera damage, also can be used as and send process to win the quality time after temporary transient hemostatic treatment is.In addition, range of application of the present utility model is not limited to abdominal part substantial viscera damage treatment, also can be applicable in the various wounds that are suitable for puncturing, the lesions treatment, solve prior art injection impact point and contained incomplete, the unbalanced problem of dosage control, reach and be beneficial to puncture, effectively injection, conveniently put the purpose of staying, overcome the defective of existing medical apparatus and instruments, fully met clinical needs.
The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, though this utility model discloses as above with preferred embodiment, any those skilled in the art, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents that can utilize above-mentioned announcement, all still belong in the scope of technical solutions of the utility model.
