Description

It is a kind of to facilitate the singlehanded push button injection device used
Technical field
The invention belongs to injector technology fields, are related to a kind of push button injection device for facilitating one hand to use.
Background technique
Being injected and being aspirated with needle tubing is clinically common technical operation, is the daily diagnosis and treatment row that must all carry out daily For.The operation and the most basic technical ability that clinical each department is closely related and doctor, nurse must grasp.But it is existing Piston is in backshank, when being aspirated in syringe in technology, it is necessary to both hands operation, a hand hold injection needle tube, The other hand hold with a firm grip piston rod carry out injection or imbibition.
As medical technology develops, to the safeties of various operations, non-invasive made higher requirement;Even if having Wound, it is also necessary to accomplish that wound minimizes.Therefore, various endoscopic techniques come into being.Can have in the various operations of Microendoscopic The clearer visual field, it is further seen that be difficult to peep and dissection dead angle, which greatly improves the safeties of various technical operations. But endoscope is needed to be stablized with a hand and be held, every technology of originally both hands operation must all be changed to one-handed performance completion. For example ear-nose-throat department treatment is dashed forward the common injection of tympanum technology such as deaf, dizziness, secretory otitis media, Microendoscopic operation both can be with It sees the form of eardrum, and injection site can accurately be selected to prevent the fine structure of damage middle ear and inner ear, it can be with See that drug injection enters the dosage and effect of tympanum.But after a hand handle holds ear endoscope, needle tubing puncture injection must be singlehanded It completes, but syringe in the prior art is extremely unstable under one-handed performance, the shaking of needle tubing syringe needle may injure external ear The structure of phonophore and other slim structures, the even important phonosensitive and maintenance balance such as damage inner ear in road, tympanum.Together When, the operations such as anaesthetic injection, abscess puncture, Irrigation are required to one-handed performance needle tubing under scope, this with regard to an urgent demand I Invent it is a kind of can one-handed performance needle tubing, make medical personnel that will vary without hand position after needle injection to disease location It is injected and suction operation.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide it is a kind of facilitate it is singlehanded use by Button formula injection device.Of the invention facilitates the singlehanded push button injection device used to be not only suitable for endoscopic one-handed performance, right Any technical operation that need to use needle tubing, all because being not necessarily to the hand position for changing inserting needle, injecting or aspirating, and keeps operation simpler Single, syringe needle is more stable, to improve safety.
To achieve the above object, the present invention adopts the following technical scheme that:
A kind of to facilitate the singlehanded push button injection device used, the push button injection device for facilitating one hand to use includes syringe With flexible transmission core bar, the flexible transmission core bar includes piston and stretching drive mechanism, and the stretching drive mechanism includes more One end of link mechanism and button, the multi-connecting-rod mechanism is connected with piston, and the other end is connected with button;The flexible transmission core Bar is mounted on syringe, and button drives multi-connecting-rod mechanism to realize in the flexible of transverse direction by the linear motion in longitudinal direction Movement, and then the piston realization of the multi-connecting-rod mechanism other end is driven to be extracted out or promoted movement in syringe.
Further, the generally body of rod of the button, the right end that longitudinal direction is threaded through the syringe are equipped with through-hole;It is described Mounting plate is transversely provided in syringe on the left of button;The multi-connecting-rod mechanism is parallel with the mounting plate.
Further, the syringe includes conveyor front barrel and rear cylinder body;The multi-connecting-rod mechanism is mounted in conveyor front barrel;It is described Button is located in rear cylinder body, and two pieces of mounting plates being parallel to each other are equipped in the rear cylinder body, and the multi-connecting-rod mechanism is located at two pieces Between the mounting plate being parallel to each other.
Further, the multi-connecting-rod mechanism includes the flexible frame body being formed by connecting by multiple telescopic units, each flexible Unit includes two cross-shaped connection sheets.
Further, the multi-connecting-rod mechanism further includes link block, passes through link block between the flexible frame body and piston It is connected, the multi-connecting-rod mechanism is set in syringe, slide plate is additionally provided on the side wall of the button, the slide plate also is located at two pieces of phases It is mutually between parallel mounting plate and parallel with mounting plate;The end of a connecting piece in the telescopic unit of the flexible frame body left end Portion is connect with link block, and the end of another connection sheet is connect with the sliding block in the sliding slot for being installed on link block;The flexible frame body The end of a connecting piece in the telescopic unit of right end is connect with button, the mounting plate in the end and syringe of another connection sheet Connection;The end for the connection sheet being connected with sliding block with and the same side in syringe of the end of connection sheet that is connected of button.
Further, each telescopic unit includes two cross-shaped the first connection sheets and the second connection sheet;Each stretch It is parallel to each other between first connection sheet of contracting unit, is parallel to each other between the second connection sheet of each telescopic unit;It is described flexible The end of the first connection sheet in the telescopic unit of frame body left end is connect with link block, the end of the second connection sheet be installed on Sliding block connection in the sliding slot of link block;The end of the first connection sheet in the telescopic unit of the flexible frame body right end passes through Slide plate is connect with button, the mounting plate connection in the end and syringe of the second connection sheet.
Further, the both ends of the connection sheet have a connecting hole, and centre is provided with fixation hole, the telescopic unit it Between connection sheet carried out by connecting hole it is hinged;It is carried out hingedly between two connection sheets in each telescopic unit by fixation hole.
