Description
Technical field
The utility model relates to medical instruments fields, relate in particular to a kind of ultrasound guided puncture needle of single saccule.
Background technique
With the improvement of living standards, the progress of medical technology, wound is small, expense is low, recovery is fast because having for Minimally Invasive Surgery
The advantages of, it has also become the preferred modus operandi of many patients.Ultrasound guidance nerve block is around gradually rising in recent years
Nerve block technique, this technology anaesthetized both at home and abroad, the attention of pain, orthopedics circle.Its great advantage is to show in real time
Show the anatomical structure of target area.Correlative study show high frequency ultrasound can allow department of anesthesia and Pain Management doctor grasp in real time into
The distribution situation of pin position and local anesthetic can be improved the safety of retardance, improve blockage effect, improves the comfortable of patient
Property.
But development of the puncture needle in ultrasonic image is bad, is that sound guides lower nerve block to deposit one of FAQs.It wears
When the development of pricker point is bad, it is easy to accidentally injure blood vessel or nerve.For the ease of observing the position of needle tip, clinically often pass through note
A small amount of liquid medicine injection is penetrated, prompts tip position near low echo area domain.But pass through continuous liquid medicine injection, in fact it could happen that medicine
Liquid is excessive, or is strayed into blood vessel, and there are potential medical-risks.
Utility model content
The utility model compensates for the deficiencies in the prior art, provides a kind of ultrasound guided puncture needle of single saccule, passes through
The situation of change for observing sacculus when being conducive to ultrasonic guidance nerve block, observes needle tip position.
The technical solution of the utility model is：A kind of ultrasound guided puncture needle of single saccule, including external pressing sacculus, ball
Capsule presses handle, physiological saline, physiological saline duct, puncture needle needle body, puncture needle needle core, puncture needle needle core inner hole and built-in expansion
Sacculus is opened, the external pressing sacculus is made of silica gel, and two sides are arc shape, and the sacculus pressing handle is located at external by pressure ball
Outside capsule, in external pressing sacculus, the puncture needle needle body is made the physiological saline by stainless steel, is double layer hollow knot
Structure, the physiological saline duct is in puncture needle needle body double layer hollow inside configuration, and the puncture needle needle core is by stainless steel material system
Make, the puncture needle needle core inner hole is used for drug injection, and the built-in dilating sacculus is made of silica gel material, with puncture needle needle body
Outer surface is glued construction, and there is cellular structure at puncture needle needle body outer surface and built-in dilating sacculus gluing position.
In use, row nerve block under ultrasound guidance, holds the ultrasound guided puncture needle of single saccule, using being worn in plane
Path is pierced, in puncture process, if when needle body or bad needle point development, holding external pressing sacculus, two fingers squeeze external press
The sacculus of pressure ball capsule two sides presses handle, physiological saline is squeezed into the intracorporal physiological saline duct of puncture needle needle, physiological saline is logical
The cellular structure for crossing puncture needle needle body outer surface enters built-in dilating sacculus, and promoting built-in dilating sacculus expansion is sacculus shape, this
When ultrasonic development under oval or circle property the low echo area domain that occurs expanding, the as position of needle tip, after puncturing in place,
By puncture needle needle core liquid medicine injection, medical fluid is injected into target position by puncture needle needle core inner hole.
The utility model has the beneficial effects that：This kind of easy Needle localization patch, hinders suitable for ultrasound guidance nerve
Stagnant art can determine the position of needle tip by the situation of change of observation balloon expandable, and development is clear, highly-safe, more paste
Nearly clinical position needs, and low in cost, structure simplifies practical.
Detailed description of the invention
Fig. 1 is main view；
Fig. 2 is A-A the schematic diagram of the section structure；
Appended drawing reference is：The external pressing sacculus of 1-, 2- puncture needle needle body, 3- puncture needle needle core, 4- puncture needle needle core inner hole,
5- physiological saline, 6- sacculus press handle, 7- physiological saline duct, dilating sacculus built in 8-
Specific embodiment
As shown in Figure 1, a kind of ultrasound guided puncture needle of single saccule, including external pressing sacculus 1, sacculus pressing handle 6,
Physiological saline 5, physiological saline duct 7, puncture needle needle body 2, puncture needle needle core 3, puncture needle needle core inner hole 4 and built-in dilating sacculus
8, the external pressing sacculus 1 is made of silica gel, and two sides are arc shape, and the sacculus pressing handle 6 is located at external pressing sacculus 8
Outside, in external pressing sacculus 1, the puncture needle needle body 2 is made the physiological saline 5 by stainless steel, is double layer hollow knot
Structure, the physiological saline duct 7 is in 2 double layer hollow inside configuration of puncture needle needle body, and the puncture needle needle core 3 is by stainless steel material
Production, the puncture needle needle core inner hole 4 are used for drug injection, and the built-in dilating sacculus 8 is made of silica gel material, with puncture needle
2 outer surface of needle body is glued construction, and there is cellular structure at 2 outer surface of puncture needle needle body and the glued position of built-in dilating sacculus 8.
In use, row nerve block under ultrasound guidance, holds the ultrasound guided puncture needle of single saccule, using being worn in plane
Path is pierced, in puncture process, if when needle body or bad needle point development, holding external pressing sacculus 1, two fingers squeeze external press
The sacculus of 1 two sides of pressure ball capsule presses handle 6, and physiological saline 5 is squeezed into the physiological saline duct 7 in puncture needle needle body 2, physiology salt
Water 5 enters built-in dilating sacculus 8 by the cellular structure of 2 outer surface of puncture needle needle body, and promoting the built-in expansion of dilating sacculus 8 is ball
Cryptomere occurs oval or circle property the low echo area domain expanded, the as position of needle tip at this time, punctures under ultrasonic development
After in place, by 3 liquid medicine injection of puncture needle needle core, medical fluid is injected into target position by puncture needle needle core inner hole 4.
It should be understood that：For those skilled in the art, before not departing from the utility model principle
It puts, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the protection scope of the utility model.
