Description

Scrape grinder

[technical field]

This utility model relates to technical field of medical instruments, and one scrapes grinder specifically.

[background technology]

Current joint disease is blue or green strong old common frdquently encountered disease, need the patient of operation very many, and tuberculosis of bone and joint is common frdquently encountered disease wherein, mostly need operative treatment, treatment is got up very thorny, thorny major reason is the formation of post-operative complication, and mostly formation such as otch disunion, second operation, the recurrence etc. of complication are failed to remove totally relevant mostly with pathological changes in art.

Operating theater instruments at present for tuberculosis of bone and joint is a lot, as curet, and bone drill etc., but lacking one goes smoothly " sharp weapon ", carries out Micro trauma removing to pathological changes.Modus operandi previously destroys heavier to the normal bone tissues of pathological changes periphery.Because the pathological changes of bone tuberculosis is hidden, position is dark, poor visibility, and patient is in order to expose pathological changes better sometimes, removes pathological changes, has excised too much tissue, finally had to carry out internal fixtion to spinal column, cause iatrogenic injury.

The pathological changes kind of tuberculosis of bone and joint is varied, pus is easy to remove, but tuberculosis granulation tissue, cheese mass and other sphacelus matter, the synovial membrane thickened, pleura fibre board, the abscess wall etc. being close to normal structure is difficult to remove, the prolongation of operating time, easily make people produce fatigue, think and remove totally, the pathological changes of in fact hiding remains.Therefore, a kind of apparatus tuberculosis being carried out to Micro trauma process (grind, scrape, inhale, rub) under lighting condition is needed.

[utility model content]

The purpose of this utility model is the defect overcoming prior art existence, and what provide a kind of new structure scrapes grinder.

For achieving the above object, design one scrapes grinder, comprise upper shell and base, bone drill chamber is provided with along inner walls in described upper shell, described bone drill intracavity is vertically provided with bone drill head, described bone drill head is by micromachine control connection, it is characterized in that, / 3rd outside wall surface of described bone bit upper end are dentation sphere, / 3rd outside wall surface are smooth sphere, residue 1/3rd outside wall surface are stepped lug, nib sphere, the lower end connection of rotating sliding sleeve of described bone drill head, the lower end outer wall face of described bone drill head is provided with external screw thread, the upper end internal face rotating sliding sleeve is provided with female thread, external screw thread and female thread suitable, fix with base bottom described rotation sliding sleeve, fix in axial rotation between described base and upper shell.

The outside wall surface hoop of described upper shell is provided with stepped annular protrusion.

Have another toroidal cavity between described bone drill chamber and inner walls, be provided with suction catheter in toroidal cavity, one end of suction catheter connects residual cavity, and the other end of suction catheter is connected with the negative pressure device outside housing via toroidal cavity.

In toroidal cavity, the side of suction catheter is other is provided with illumination channel, and run through optical fibers and illuminating device in described illumination channel, the end of described optical fibers and illuminating device is connected with the display outside housing via illumination channel.

This utility model has following technique effect:

1. this apparatus can grind bone tuberculosis pathological changes, scrapes, inhales, the operation such as rub, and reaches Micro trauma object;

2. attract and illumination simultaneously, be conducive to appearing pathological changes;

3. pathological changes can be amplified by external-connection displayer, and retains operation video;

4. accurately can process key aspect pathological changes, as epidural, the spinal column rear foot, articular surface etc.;

5. can process the pathological changes that pulmonary cavity, empyema and intraperitoneal not easily excise completely.

Description of symbols in figure

1 upper shell, 2 bases, 3 bone drill chambeies, 4 bone drill heads, 1/5th three dentation sphere, / 6th three smooth sphere, 1/7th three stepped lug, nib sphere, 8 rotate sliding sleeve, 9 external screw threads, 10 female threads, 11 stepped annular protrusions, 12 toroidal cavities, 13 suction catheters, 14 illumination channel.

[detailed description of the invention]

Now by reference to the accompanying drawings and embodiment the technical solution of the utility model is further elaborated, believe it is clearly for a person skilled in the art.

One scrapes grinder, comprises upper shell and base, and is provided with bone drill chamber along inner walls in described upper shell, described bone drill intracavity is vertically provided with bone drill head, described bone drill head by micromachine control connection, variable speed, wherein:

Bone drill head, as shown in Figure 2, / 3rd outside wall surface of its upper end are dentation sphere, and 1/3rd outside wall surface are smooth sphere, and residue 1/3rd outside wall surface are stepped lug, nib sphere, the lower end connection of rotating sliding sleeve of described bone drill head, the lower end outer wall face of described bone drill head is provided with external screw thread, rotates the upper end internal face of sliding sleeve and is provided with female thread, external screw thread and female thread suitable, fix with base bottom described rotation sliding sleeve, fix in axial rotation between described base and upper shell.Can be fixing between bone drill head and rotation sliding sleeve, also can be removable at any time.

The outside wall surface of upper shell, as shown in Figure 1, hoop is provided with stepped annular protrusion.

Have another toroidal cavity between bone drill chamber and inner walls, be provided with suction catheter in toroidal cavity, one end of suction catheter connects residual cavity, and the other end of suction catheter is connected with the negative pressure device outside housing via toroidal cavity.

Above-mentioned operational approach of scraping grinder, step is as follows:

During use, rotate clockwise base, base drives and rotates sliding sleeve rotating in same direction, external screw thread and the incorgruous relative rotation of female thread of rotating sliding sleeve of bone drill head, bone drill head and rotate sliding sleeve oppositely from, bone drill head produces via the top in bone drill chamber, controls rotation by micromachine;

When bone drill head stops operating, utilize 1/3rd outside wall surface of bone bit upper end to be dentation sphere, 1/3rd outside wall surface are smooth sphere, and residue 1/3rd outside wall surface are stepped lug, nib sphere, implement respectively to grind, scrape, rub operation;

Finish using, rotate counterclockwise base, base drives and rotates sliding sleeve rotating in same direction, the external screw thread of bone drill head and the incorgruous relative rotation of female thread of rotation sliding sleeve, and bone drill head and the indentation in opposite directions of rotation sliding sleeve, bone drill head is via the top indentation in bone drill chamber.

Have another toroidal cavity between bone drill chamber and inner walls, grinding, scrape, rubbing in operating process, can carry out residual cavity via the suction catheter established in toroidal cavity and attract operation, attraction is attracted to via suction catheter in the negative pressure device outside housing.

In attraction process, carry out illumination via the optical fibers in the illumination channel that suction catheter side is other and illuminating device, the end of described optical fibers and illuminating device is connected with the display outside housing via illumination channel, can derive via display image.

When finishing using, bone drill head is via after the top indentation in bone drill chamber, and the stepped annular protrusion continuation that the outside wall surface hoop of upper shell still can be used to be provided with is ground, scrapes, rubbed operation.
