CN2178097Y - Electric dissector - Google Patents

Abstract

The utility model relates to an electric dissector composed of a saw blade 1, a handle 14, a motor 13, a housing 12 and a switch 16. The utility model is characterized in that the front part of the housing 12 is connected with a spring 18 through two extension arms; a T-shaped element 10 is arranged on the top of the spring 18; a nut 17 arranged above the T-shaped element 10 is matched with a sleeve 7; the top and the bottom of the sleeve 7 as well as the T-shaped element are fixed to the inner side surface of a saw guard 2 with the middle position provided with an inverted V-shaped groove 20. The utility model has the advantages that the saw guard 2 is provided with a lifting adjustable spring, and the bottom of the saw guard always contacts surface of bone, accordingly, the utility model can avoid bone powder splashing and control cutting depth in order not to damage the organs.

Description

Electric dissector

This utility model belongs to the obduction technical field.

Legal medical expert worker does not also have special-purpose obduction instrument at present, and is not only time-consuming but also require great effort, very inconvenient when carrying out when dissected just by some apparatus of medical surgery, particularly opens cranium and dissects difficulty especially.

Order of the present utility model solves this long-standing practical problem exactly, invents out the special-purpose dissector of a kind of labour-saving legal medical expert simple in structure, practical and convenient, quick.

This utility model is achieved in that a kind of electronic dissector, by saw blade, handle, motor, shell, circumscripted power line and switch are formed, it is characterized in that: the front end at shell has two cantilever arms, saw cover medial surface has a pair of lifting spring, T type spare of the welded top of spring, a bottom welding round-meshed steel plate, steel plate is fixed on the cantilever arm of motor shaft, two T type spares are fixed on saw cover inboard up and down, following T type spare is connected and fixed with spring shaft, a sleeve pipe is arranged on the spring shaft, but tighten telescopic jackscrew restraining spring along the axle decline scope in the precalculated position.But saw cover medial surface has one to tighten telescopic jackscrew restraining spring along the axle decline scope.Saw cover medial surface has an inverted U-channel, and motor shaft is moved up and down to drive saw blade rotation cutting osseous tissue.

Advantage of the present utility model is: because the saw cover is equipped with the lifting adjustable spring, contacted the cover end all the time with surface of bone, can avoid the bone end to splash, also can grasp depth of cut, in order to avoid damage the stolen goods device.

Be described further below in conjunction with accompanying drawing.

Fig. 1 is a cutaway view of the present utility model;

Fig. 2 is the connection layout of saw cover with lifting spring;

Fig. 3 is the binding figure of shell and handle.

Referring to accompanying drawing, in motor 13 was fixed on by shell, motor shaft 5 was by the fixing saw blade 1 of nut 3 and pad 4, and saw blade 1 can cut osseous tissue.Be connected and fixed by cantilever arm 6 and the band circular hole steel plate 19 that is welded on the spring lower end in shell 12 front end both sides, spring 18 and quill 7 cooperate, a T shape part is fixed with nut in the quill lower end, and spring upper end welding one T shape part, two T shape parts are fixed on the saw cover medial surface.When saw blade 1 incision osseous tissue, spring 18 elongates like this, and saw cover 2 contacts surface of bone all the time, thereby avoids the bone end to splash.Fix one in the bottom of quill by screw 8 and highly control sleeve pipe 9,, saw blade can not endlessly down be cut, in order to avoid damage internal organs with the control spring falling head.Have U-lag 20 in the middle of the inner face of saw cover 2, motor shaft is achieved with relative the drawing back of saw cover together with saw blade.But motor power-supply wire 11 is drawn external power supply through the hole.On the top of shell 12 bowhandle 14 is arranged, a switch 16 is set on the handle.

Front portion at shell 12 links to each other in spring 18 by two cantilever arms, one T shape part 10 is arranged at the top of spring 18, on T shape part 10, there is a nut 17 to cooperate with quill 7, the top of quill 7, end T shape part are fixed on the medial surface of saw cover 2, position has a side adjustable spring in the middle of it, and the cover end contacts with surface of bone all the time.

Saw cover 2 is made by lucite or transparent offset plate.

Claims (3)

1, a kind of electronic dissector, by saw blade (1), handle (14), motor (13), shell (12) and switch (16), it is characterized in that: the front portion at shell (12) links to each other in spring (18) by two cantilever arms, one T shape part (10) is arranged at the top of spring (18), on T shape part (10), there is a nut (17) to cooperate with quill (7), the top of quill (7), end T shape part are fixed on the medial surface of saw cover (2), position has a side adjustable spring in the middle of it, and the cover end contacts with surface of bone all the time.

2, electronic dissector according to claim 1 is characterized in that: handle (14) is an arc;

3, electronic dissector according to claim 1 is characterized in that: saw cover (2) is made by lucite or transparent offset plate.
