Description
Technical field
The present invention relates to oral cavity medical apparatus, be specifically related to a kind of dental handpiece.
Background technology
Dental handpiece is a kind of conventional oral cavity medical apparatus, different shape car pin is coordinated by high speed rotating, boring can be positioned to oral hard tissue, expand or even cut, dental handpiece (see figure 1) conventional at present, comprise handle 1, be positioned at the hand machine head 2 of handle one end, be positioned at the outer and car pin 3(outside appurtenances be connected with hand machine head 2 by dop of head 2, different shape length needs with the use of); But because the car pin 3 of dental handpiece is when existing doctor holes to patient in implant operation, being difficult to hold to the degree of depth drilled through, is the experience by doctor completely; Such as doctor needs to drill through 10 millimeters downwards to the tooth of patient, but in brill tooth process, it is how dark that doctor can only go judgement to bore with the scale on car pin 3, individual's sensation and experience, 8 millimeters may be just drilled through, but doctor but thinks and reaches predetermined 10 millimeters, because car pin 3 is in order to coordinate the implant hole drilling through different depth usually, have multiple scale, easily because sight equation produces error in operation process, or even drill through the degree of depth exceed expection thus injure neurocele or maxillary sinus, make operation process can not get ensure.
Summary of the invention
The object of the invention is to the deficiency overcoming the existence of above-mentioned prior art, and provide one can improve security performance, effectively prevent from accidentally injuring, and doctor can be helped to control to drill through the degree of depth, ensure the dental handpiece of surgical effect.
The present invention seeks to realize like this:
A kind of dental handpiece, comprise hand machine head, hand machine head bottom is provided with car pin, and described car pin outside is provided with safety sleeve, and safety sleeve is connected with hand machine head, and the lower end of car pin is stretched out outside safety sleeve.
Safety sleeve of the present invention is divided into two kinds, one is external screw thread safety sleeve, one is female thread safety sleeve, the external wall of upper portion of external screw thread safety sleeve is provided with screw thread, female thread safety sleeve is then that the upper inside wall of sleeve is provided with screw thread, the diameter of usual female thread safety sleeve is larger, be applicable to the dental operation of general position, the oral cavity of energy available protecting patient, prevent from accidentally injuring, the length difference of safety sleeve and car pin can also be utilized to help doctor to control to drill through the degree of depth simultaneously, and when the position running into patients need operative is comparatively narrow, when female thread safety sleeve can not enter, external screw thread safety sleeve will be used, usual external thread sleeve diameter is less, the oral cavity that narrower position is patient can be entered protection is provided.
Technique scheme also can be made to the following further improve.
Described hand machine head bottom is provided with sleeve connection mouth, sleeve connection mouth internal perisporium is provided with the first female thread, safety sleeve external wall of upper portion is provided with first external screw thread corresponding with the first female thread, and the first external screw thread and the first screw-internal thread fit, make safety sleeve be fixed on hand machine head.
Described hand machine head bottom is provided with sleeve connection mouth, sleeve connection mouth periphery wall is provided with the second external screw thread, safety sleeve upper inside wall is provided with second female thread corresponding with the second external screw thread, and the second female thread coordinates with the second external screw thread, and safety sleeve is fixed on hand machine head.
Described sleeve connection mouth can be provided with the first female thread and the second external screw thread simultaneously, to facilitate adaptive dissimilar safety sleeve.
The sidewall of described safety sleeve has Cooling Holes, can be cooled to car pin by Cooling Holes over the course for the treatment of.
Described safety sleeve has the length of multiple different size, to be applicable to different positions and disease.
Compared with prior art, beneficial effect of the present invention is as follows.
The present invention, by setting up safety sleeve in hand machine head bottom, reaches the security performance that effectively can improve dental handpiece, prevents the accidental injury produced in operation process; And by the safety sleeve at hand machine head bottom collocation different-diameter and length, can effectively control to drill through the degree of depth, effectively ensure the presupposed solution obtaining operative treatment, guarantee therapeutic effect; And safety sleeve can also with plantation guide plate with the use of, the position of the boring of implant in implant operation, angle and the degree of depth can be guaranteed, guarantee surgical effect to greatest extent.

Detailed description of the invention
Below in conjunction with drawings and Examples, many present invention are described further.
Composition graphs 2 to Fig. 4, is described in detail to embodiment 1.
A kind of dental handpiece, comprise hand machine head 2, hand machine head 2 bottom is provided with car pin 3, and the outside of car pin 3 is provided with external screw thread safety sleeve 5, and external screw thread safety sleeve 5 is connected with hand machine head 2, and the bottom of car pin 3 stretches out in outside external screw thread safety sleeve 5.
Described hand machine head 2 bottom is provided with sleeve connection mouth 4, sleeve connection mouth 4 internal perisporium is provided with the first female thread 41, external screw thread safety sleeve 5 external wall of upper portion is provided with first external screw thread 51 corresponding with the first female thread 41, first external screw thread 51 coordinates with the first female thread 41, and external screw thread safety sleeve 5 is fixed on hand machine head 2.
The sidewall of described external screw thread safety sleeve 5 has Cooling Holes 88, can be cooled, with the damage avoiding high temperature to produce sclerous tissues to because of car pin 3 heat that high-speed rotary transfers to produce in sclerous tissues by Cooling Holes 88 over the course for the treatment of.
