Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provides a kind of bone cement injector for micro-wound surgical operation.During use, the head of syringe is aimed at injury place, then promote push button backward forward and can complete injection, whole process is convenient and swift stable, substantially reduce behaviour's institute's time, avoid because bone cement injects not in time, the problem of injury place poor mechanical property after the treatment that new dirt enters injury and causes.
The technical solution adopted in the utility model is: provide a kind of bone cement injector for micro-wound surgical operation, comprise sacculus, cylinder body; Cylinder body comprises A chamber, B chamber, double-head piston, and with the slip push button of double-head piston concrete mutually, the top in B chamber is provided with aperture, is sealed with sealing-plug in aperture; The upper end of sacculus is communicated with outer tube, and outer tube is connected with the A chamber of cylinder body by airway; Through outer tube and sacculus, with the coaxial direction of outer tube on be provided with syringe, syringe is provided with Anti-stop cover in the lower end of sacculus, and the other end of syringe is connected with B chamber.
Further optimization the technical program, the outer surface for the sacculus of the round tray of the bone cement injector of micro-wound surgical operation is provided with the projection along outer tube axis direction.
Further optimization the technical program, the top for the outer tube of the bracing piece of the bone cement injector of micro-wound surgical operation is provided with sleeve, and the inclined upward of sleeve is provided with handle.
Further optimization the technical program, is provided with heat exchanger, heat exchanger is provided with water inlet and outlet on the syringe of the bone cement injector of micro-wound surgical operation.
This utility model is compared with traditional bone cement injection tool, and its beneficial effect is: when 1, using, and the head of syringe is aimed at injury place, opens the aperture above B chamber, promote push button backward, airbag aeration is expanded, thus got rid of by the bloodstain dirt at injury place; Bone cement is injected from aperture, cover the sealing-plug of aperture, promote push button forward, air bag shrinks, bone cement is injected into injury place by syringe simultaneously, sacculus one end of syringe is provided with Anti-stop cover, bone cement is flowed out from the edge of Anti-stop cover, prevents it to be plugged in injection process, whole process is convenient and swift stable, substantially reduce behaviour's institute's time, avoid because bone cement injects not in time, the problem of injury place poor mechanical property after the treatment that new dirt enters injury and causes; 2, the outer surface of sacculus is provided with the projection along outer tube axis direction, facilitates bloodstain dirt to flow out from projection; 3, the top of outer tube is provided with sleeve, and the inclined upward of sleeve is provided with handle, conveniently gives paraprofessional personnel by the work of fixture and completes, and surgical staff controls speed and the amount of bone cement injection by all means, greatly must reduce the difficulty of operation; 4, syringe is provided with heat exchanger, heat exchanger is provided with water inlet and outlet, heat exchanger can make bone cement just have certain temperature before injection injury place, makes it must merge with injury place faster, shortens the time of operation.
