Abstract

The utility model relates to an electric grinding drill in a surgical operation for a vertebral column. The utility model is composed of an electric drill stand, a motor, a foot switch, a soft tail end shaft, a speed regulating switch, etc. The electric grinding drill can replace surgical instruments used in a surgical operation for a vertebral column, such as bone teeth, bone knives, bone hammers, bone rongeurs, etc. The utility model can grind a bone, can cut a bone, etc. The utility model overcomes the defects that the power parts of an existing pneumatic grinding drill and an existing electric grinding drill are positioned at handles, motors and pneumatic impeller blades are easily wetted when formaldehyde vapor is used for steaming and sterilization, partial electrical apparatus elements are rusted and corroded, circuit faults and mechanical faults occur, and usage is affected. The utility model has the advantages of low manufacturing cost, simple operation, and high safety.

Description

The abrasive drilling of orthopaedics electric power

This utility model belongs to medical instruments field, specifically, is a kind of orthopaedics electric power abrasive drilling of using in spinal surgery.

The electric drill that is exclusively used in spinal surgery at present is existing several, bore and home-made pneumatic, Electric grinding drill etc. as: StryyerShi, but the power section of above abrasive drilling is at the handle place, motor and air impeller blade make moist when the formaldehyde vapors fumigation easily, part electric elements metal is because of getting rusty, corroding, and causes circuit and mechanical breakdown and influences use.

To be that design is a kind of replace in the past operating theater instruments such as employed bone tooth, osteotome, bone hammer, rongeur in the spinal surgery to the purpose of this utility model, can carry out bone mill, cut, work such as cutting, low cost of manufacture, orthopaedics Electric grinding drill simple to operate, safe.

This utility model such as Fig. 1, shown in Figure 2, Electric grinding drill is mainly by electric drill stand 19, motor 10, foot switch 6 and end shaft of soft vehicle are formed, the rotating speed of motor 10 is 3000 rev/mins--adjustable between 10000 rev/mins, by crank arm 20 and regulating shaft 18 join with electric drill stand 19, one end of cranking arm is equipped with the tailing axle of changing trains or buses by steering spindle 12, end shaft of soft vehicle is made up of Great Wall Software's axle core 13 sheaths 14 and overcoat 15, sheath 14, overcoat 15 are the soft overcoat of steel, are provided with straight handpiece 16 in the end, limit of major axis core, guided bearing cover 4, supporting fixed screw 3 and straight handpiece headstock 1 in the outside of straight handpiece, are with sheath 21, the afterbody of sheath has gathering sill 5 and sheath fixed screw 2, round bur 17 is housed on straight handpiece headstock 1, is provided with driving-belt 11 between Great Wall Software's axle core and the motor 10, on electric drill stand, also be provided with to adjust and go back device 8 and power supply indicator 9, also be connected with foot switch 6 and attaching plug 7 by lead.

This utility model compared with prior art can replace with operating theater instruments such as the bone tooth of living the use in the spinal surgery, osteotome, bone hammer, rongeurs, can carry out bone mill, cut, work such as cutting.And motor or the air impeller blade having avoided fully existing in the pneumatic or Electric grinding drill in the prior art make moist when the formaldehyde vapors fumigation is sterilized easily, part electric elements metal is because of getting rusty, corroding, cause circuit and mechanical breakdown and influence the deficiency of use, low cost of manufacture, simple to operate, safe.
