This kind of supersound bone saw's working head, including work portion and with the perpendicular connecting rod that links to each other of work portion, still include the cylinder body of rod continuous with the connecting rod, work portion side edge be equipped with the sawtooth, this work portion includes head end and tail end, head end to tail end is under the narrow width, a head end side be the inclined plane. The utility model discloses a supersound bone saw working head simple structure, the flexible operation reduces bone tissue lesion degree when improving deep efficiency, and the practicality is strong.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of ultrasonic bone saw, specifically relates to a kind of working head of ultrasonic bone saw.
Background technology
In dental care process, according to circumstances need to carry out Extended lift to alveolar bone hole, because oral cavity space is narrow, special-purpose surgical knife performance difficulty in operation process that odontologist uses, ultrasonic bone saw is that one utilizes vibration of ultrasonic wave cutting, and existing ultrasonic bone saw is low by structural limitations cutting efficiency.
For solving the problem, Authorization Notice No. CN200942107Y discloses a kind of ultrasonic bone saw cutter head, and comprise knife bar and blade, blade is positioned at knife bar front end, and blade front end, with sawtooth, is characterized in that: on blade the flank of tooth of sawtooth and knife bar centrage perpendicular.Though the ultrasonic bone saw cutter head of this utility model can reach cutting effect but easy damaged osseous tissue and malfunction.
Utility model content
For overcoming deficiency of the prior art, this utility model provides a kind of structure simple, and the cutting output controlling bone block during ring cutting bone hole reduces the degree of injury of osseous tissue simultaneously.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of working head of ultrasonic bone saw, comprise operate portions and the connecting rod that be connected vertical with operate portions, also comprise the cylinder body of rod be connected with connecting rod, described operate portions side edge is provided with sawtooth, this operate portions comprises head end and tail end, head end to tail end is up-narrow and down-wide, and described head end one side is inclined-plane.
Further, described operate portions cross section is greater than the cross section of connecting rod.
Further, described operate portions tail end arc length is 3.0mm, head end arc length≤3.0mm, and thickness is 0.5 ~ 1.0mm.
Further, the thickness of described connecting rod is 1.5 ~ 2.0mm, and width is 1.5 ~ 3.0mm.
Further, described ultrasonic bone saw working head is made up of medical rigid abrasion-proof stainless steel.
Further, the flexibility of described ultrasonic bone saw working head operate portions head end, the head of connecting rod, tail end is identical and be greater than corresponding bone hole edge flexibility.
From above-mentioned to description of the present utility model, compared with prior art, the ultrasonic bone saw working head structure of one of the present utility model is simple, flexible operation, reduces osseous tissue degree of injury while improving deep efficiency, practical.

Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
Shown in Fig. 3, a kind of working head of ultrasonic bone saw, comprise operate portions 1, with the vertical connecting rod 2 be connected of operate portions and the cylinder body of rod 3 be connected with connecting rod 2, right angle is formed between described operate portions 1 and connecting rod 2, described operate portions 1 cross section is greater than the cross section of connecting rod 2, the thickness of described connecting rod 2 is 1.5 ~ 2.0mm, and width is 1.5 ~ 3.0mm; Described operate portions 1 side edge is provided with sawtooth 11, and this operate portions comprises head end 12 and tail end 13, and head end 12 to tail end 13 is in up-narrow and down-wide, described operate portions tail end arc length is 3.0mm, head end arc length is≤3.0mm, and thickness is 0.5 ~ 1.0mm, and described head end one side is inclined-plane 14; The head of ultrasonic bone saw working head operate portions 1 head end 12, connecting rod 2, the flexibility of tail end are identical, and are greater than hole, corresponding bone hole edge flexibility;
The working head of described ultrasonic bone saw is hard, wear-resistant medical stainless steel.
Specific embodiment 1: shown in Fig. 2, the using method of this ultrasonic bone saw working head is: screwed with tooth-cleaning machine tube expander head by the ultrasonic bone saw cylinder body of rod 3, be connected with tooth cleaner handgrip again and be tightened, ultrasonic bone saw working head stretches at the bottom of hole, bone hole and is less than the thick annular hole of 1.0mm by piezoelectric ultrasonic vibration toward hole edge trepan, and in trepan process, working head can back exiting adjustment direction carries out trepan upper jaw bone for several times.
Specific embodiment 2: with reference to shown in Fig. 1 and Fig. 3, use operate portions connecting rod when the ultrasonic bone saw of hole edge breach, first entered being positioned at hole edge indentation, there the position of connecting rod 2, then carry out trepan, in trepan process, working head can back exiting adjustment direction carries out trepan upper jaw bone for several times.
Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design this utility model to be carried out to unsubstantiality, all should belong to the behavior of invading this utility model protection domain.
