Description
Technical field
The invention belongs to technical field of medical instruments, particularly a kind of tooth chair head holder.
Background technology
Tooth chair is necessary equipment in dental diagnostic process, but in the daily diagnosis and treatment process of doctor, patient is teenager colony especially, often owing to worrying or fearing pain in diagnosis and treatment process, cause head to have unconsciously displacement by a relatively large margin, and this is existing very frequent, it is too much that this causes head to depart from diagnosis and treatment position, cause oral cavity doctor to carry out position adjustment to viewfinder continually, this process expends time in very much, greatly limit oral cavity doctor's diagnosis and treatment efficiency, cause that patient's queuing time is long below, this is also to cause the major reason that consulting room is too crowded and quarrel.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of tooth chair head holder is provided, it can effectively stop head in patient's diagnosis and treatment process and significantly be shifted after being fixed on the headrest of tooth chair, improves oral cavity doctor's diagnosis and treatment efficiency.
To achieve these goals, technical scheme of the present invention is as follows: a kind of tooth chair head holder, comprise fixed bar, on fixed bar, be provided with for the fixing connecting portion of tooth chair head headrest, the two ends of fixed bar are connected with crank, the surface that the end of crank is provided with is provided with flanged supporting disk, in the middle of flange, have internal thread hole, the arranged outside of supporting disk has adjustment plate, the inner side of supporting disk is provided with chuck, adjustment plate has first double-screw bolt that is positioned at flange internal thread hole, in the first double-screw bolt, offer internal thread hole, chuck has second double-screw bolt that is positioned at the first double-screw bolt internal thread hole, flange, the first double-screw bolt, the second double-screw bolt three realizes the secondary spacing adjustment of chuck.
As further technical scheme; described fixed bar comprises sleeve and the rotating shaft through sleeve; the shaft shoulder is arranged at the two ends of sleeve; sheathed inner side protective disc, the rotating disk with latch, rubbery friction ring on the shaft shoulder; crank is connected to the end of rotating shaft, and the side that crank is connected with rotating shaft is provided with the crank chute coordinating with the latch of rotating disk, and the arranged outside of the end of rotating shaft has protective plate; the edge of protective plate offers 120 ° of chutes, and crank can rotate as the center of circle along 120 ° of chutes taking rotating shaft.
The invention has the beneficial effects as follows: when use, make the chuck of crank both sides prop up patient's chin both sides, patient opens after face just double swerve more not of patient's head.In diagnosis and treatment process, needs of patients is spitting ptysis continually, and chuck only props up patient's chin, and the non-gear of chuck is at patient's forehead place, and patient comes back slightly and just can turn round spitting ptysis.Between supporting disk and adjustment plate, realize the lateral displacement adjustment of one-level, between adjustment plate and chuck, realize the lateral displacement adjustment of secondary.Chuck props up after patient's chin, can effectively prevent that in patient's diagnosis and treatment process, head moves, and doctor need not adjust the position of viewfinder continually, has increased substantially doctor's diagnosis and treatment efficiency.
