The automatic thruster comprises a shell; a linear motor, a pushing rod, and a locking device capable of locking a needle bar to connect with the pushing rod, which are sequentially connected, are arranged in a hollow pipeline in the shell; a pressure sensor is further arranged on the pushing rod; and the pressure sensor is connected with a signal processing host with an alarm. According to the automatic thruster of the intelligent syringe needle, provided by the utility model, the needle bar is driven by the linear motor, the syringe needle is pushed to advance at a uniform speed to enter a muscular tissue of inner side of mandibular ramus, and the inferior alveolar nerve tissue is anaesthetized by injecting anesthetic, thereby painless inferior alveolar nerve block anesthetic injection is realized, particularly, when bone block happens, the pressure sensor can automatically sense the change of the advancing resistance, thereby, the in-time avoidance can be realized, and the purpose of safe and painless injection for the inferior alveolar nerve block anesthesia can be realized.
Description
Technical field:
This utility model belongs to medical instruments field, is specifically related to a kind of automatic propeller of intelligent injection syringe needle that can be used in block anesthesia of inferior alveolar nerve.
Background technology:
Pain is to cause the patient to feel frightened one of the main reasons for dental care, and it is particularly remarkable wherein to implement the pain that the local anesthesia injection caused.Report is arranged, surpass 25% adult at least and fear the pain that acupuncture causes and therefore do one's utmost to avoid or evade necessary dental care.Than emerging in an endless stream of local anesthetic and updating of pharmaceutical property; Since Charles Pravaz in 1853 and Alexander Wood invention and first Application hollow needle cartridge type hypodermic syringe; The injector designed of implementing the local anesthesia injection almost never has too about-face, and modern used local anesthesia set and pattern at that time still have surprising concordance.Traditional needle cylinder injection device causes acupuncture pain unavoidable, and for many years, how relevant expert scholar is for to alleviate and even avoid injectivity pain to carry out a series of unremitting efforts, and wherein slow injection is one of method wherein relatively more commonly used.But,, reach the purpose that reduces pain through the injection speed that slows down and be difficult to realize fully because the limitation of human body is implemented slow injection with conventional syringe and is difficult to accurate control rate.Present micro-processor controlled part painless anesthesia injection appearance can accurately be controlled injection speed through computer software programs and Mechatronic Systems, make its maintain a kind of low speed low pressure state, human body sensory is not obvious less than pain or pain during injection.The application of the local painless anesthesia injection appearance of microcomputer in infiltration anesthesia of mouth (comprising PDL anesthesia) is more, can significantly reduce injection pain, reduces the anaesthetic consumption, accurately controls the anesthesia scope and obtain the good anesthesia effect.But the scope that the part operation technique of oral cavity alveolus surgery relates to is wider, and especially the radicular cyst of lower jaw or impacted wisdom tooth etc. only rely on infiltration anesthesia or PDL anesthesia can not reach the purpose of painless surgical operation, must implement block anesthesia of inferior alveolar nerve.Existing painless anesthesia injection appearance only can be controlled the injection speed of medicinal liquid, generally is used for infiltration injecting under the oral mucosa, and needle point thrusts and promptly no longer continues under the mucosa to advance, and continues inserting needle if desired, just can only rely on people's hand control to advance.Because the block anesthesia of inferior alveolar nerve injection belongs to intramuscular injection, relates to the propelling in muscular tissue of injecting liquid drug and syringe needle simultaneously, according to the requirement of slow injection, need control injecting liquid drug speed and syringe needle fltting speed simultaneously.Because the restriction of the physiology of human body, people's hand control steadily advances syringe needle that certain difficulty is arranged at a slow speed and evenly, and if can not be steadily at the uniform velocity at a slow speed propelling syringe needle, only rely on automatically injection liquid at a slow speed, it is relatively more difficult thoroughly to control injectivity pain.Existing painless anesthesia injection appearance can't satisfy the needs of block anesthesia of inferior alveolar nerve, is also having improved necessity aspect the automatic propelling of syringe needle.
Summary of the invention:
The purpose of this utility model provides a kind ofly can control at the uniform velocity inserting needle of injection needle automatic steady;, syringe needle can give the alarm when running into sclerotin and stop; Stop the syringe needle motion; So that the doctor in time adjusts the syringe needle angle and avoids sclerotin continued inserting needle to the degree of depth that needs, finally realize the automatic propeller of intelligent injection syringe needle of block anesthesia of inferior alveolar nerve safety painless injection.
This utility model is achieved through following technical scheme:
The automatic propeller of intelligent injection syringe needle of this utility model; It is characterized in that; Comprise shell, be provided with linear electric motors, the pushing ram that connects successively in the pipeline of hollow in the enclosure and can lock shank, the locking device that it is connected with pushing ram; On pushing ram, also be provided with pressure transducer, described pressure transducer links to each other with the signal processing main frame that has siren.
Described pressure transducer preferably is located at the top of pushing ram.Pressure transducer is located at the top can put on the pressure on the shank by more sensitive perception pushing ram.
This utility model is operation like this: the shank that will have syringe needle is fixed on the pushing ram through locking device.Shank is disposable revocable interim accessory, is market general article on sale, during use handle portion is inserted in the locking device to get final product, and the flexible pipe with the syringe needle rear end links to each other with the medicament ampere again.The degree of depth of thrusting through engine control system control syringe needle; Linear electric motors running then drives pushing ram and advances, and the progressive pressure of pressure transducer perception pushing ram changes; Shank is under the propelling of pushing ram; Drive syringe needle and at the uniform velocity also finally arrive at desired depth in propelling entering mucosa, the muscular tissue automatically, the injection anaesthetic is anaesthetized the long nerve of cheek, nervus lingualis, inferior alveolar nerve tissue successively.When in syringe needle is not arriving at the way of desired depth, running into sclerotin; Progressive resistance increases; Resistance through syringe needle, shank, be transmitted to pressure transducer, the pressure of pressure transducer perception shank increases, and transfers signals to the signal processing main frame; The signal processing main frame sends instruction guiding siren warning and stops to continue the propelling syringe needle, and the doctor can in time adjust the angle or the degree of depth of syringe needle and avoid sclerotin continued inserting needle to the deeper injection anaesthetic that needs.
The automatic propeller of intelligent injection syringe needle of this utility model drives shank through linear electric motors, and the promotion syringe needle at the uniform velocity advances and gets in the inboard muscular tissue of mandibular ramus, and the injection anaesthetic; Anesthesia inferior alveolar nerve tissue, nervus lingualis and cheek are long neural; Thereby realize painless anesthesia injection, when running into sclerotin and stop, pressure transducer is the progressive change in resistance of perception automatically especially; Can in time avoid, realize the purpose of block anesthesia of inferior alveolar nerve safety painless injection.
