Description
[technical field]
The present invention relates to technical field of medical instruments, specifically one kind scrapes grinder and its operating method.
[background technology]
Current bone and joint diseases are blue or green strong old common frdquently encountered diseases, it is necessary to the patient of operation is very more, and tuberculous osteoarthropathy
It is common frdquently encountered disease therein, operative treatment is needed mostly, treatment gets up very intractable, and intractable major reason is postoperative complications
Formation, and mostly the formation of complication such as otch disunion, second operation, recur to fail with lesion in art to remove mostly and do
It is net relevant.
Operating theater instruments currently used for tuberculous osteoarthropathy is a lot, such as curet, bone drill etc., but is a lack of one kind and goes smoothly " profit
Device ", Micro trauma removing is carried out to lesion.Normal bone tissues destruction of the modus operandi of the past to lesion periphery is heavier.Because of bone knot
The lesion of core is hidden, and position is deep, it is seen that degree is poor, and patient removes lesion to preferably expose lesion sometimes, has cut off excessively
Tissue, finally having to, it is interior fixed that backbone is carried out, and causes iatrogenic injury.
The lesion species of tuberculous osteoarthropathy is varied, and fester is easy to remove, but tuberculosis granulation tissue, cheese mass
And other sphacelus matter, the synovial membrane thickened, pleura fiberboard, it is close to abscess wall of normal structure etc. and is difficult to clean off, operating time
Extension, easily make one to produce fatigue, think and removed clean, the lesion actually hidden is remained.Accordingly, it would be desirable to which one kind exists
The apparatus of Micro trauma processing (grind, scrape, inhaling, rubbing) is carried out under lighting condition to tuberculosis.

The above-mentioned operating method for scraping grinder, it is characterised in that
In use, rotating clockwise base, base drives rotation sliding sleeve to rotate in same direction, and the external screw thread of bone drill head is slided with rotating
The internal thread of set is incorgruous to be rotated against, bone drill head with rotating sliding sleeve reversely from, bone drill head via being produced at the top of bone drill chamber, by
Micromachine control is rotated；
It is outside dentation sphere, 1/3rd using 1/3rd outside wall surfaces of bone bit upper end when bone drill head stops operating
Wall is smooth sphere, and remaining 1/3rd outside wall surfaces are stepped lug, nib sphere, implements grind, scrape, rubbing operation respectively；
Using finishing, base is rotated counterclockwise, base drives rotation sliding sleeve to rotate in same direction, the external screw thread of bone drill head and rotation
The internal thread of sliding sleeve is incorgruous to be rotated against, and bone drill head is retracted in opposite directions with rotating sliding sleeve, and bone drill head is retracted via the top of bone drill chamber.
There is another toroidal cavity between bone drill chamber and inner walls, grinding, scrape, rub in operating process, can be via annular
The suction tube set in cavity carries out residual cavity and attracts operation, and attraction is attracted in the negative pressure device outside housing via suction tube.
During attraction, light is carried out via the optical fiber and illuminating device in the illumination passage by suction tube side
According to the end of the optical fiber and illuminating device is connected via illumination passage with the display outside housing, can be via display
Device image is exported.
When using finishing, after bone drill head is retracted via the top of bone drill chamber, still the outside wall surface ring of upper shell can be used to set
The stepped annular protrusion having continues grind, scrape, rubbing operation.
The present invention has following technique effect：
1. an apparatus such as can be ground, scrape, inhale, rubbing at the operation to bone tuberculosis lesion, Micro trauma purpose is reached；
2. attract and illumination simultaneously, be conducive to appearing lesion；
3. external-connection displayer can amplify lesion, and retain operation video；
4. key aspect lesion can accurately be handled, such as Epidural cavity, the backbone rear foot, articular surface；
5. lung cavity, pyothorax can be handled and intraperitoneal complete resection of lesion is difficult.
