In addition, the retractor for brain surgery according to the above embodiment of the present invention may have the following additional technical features:

in the utility model, a fixer crank handle 12 is arranged on the movable arm of the retractor for brain surgery, a U-shaped clamping groove 3 is arranged on the inner sides of the fixed arm and the movable arm, the movable arm slides on the rack plate of the fixed arm by shaking the fixer crank handle 12, and the U-shaped clamping groove fixes the whole instrument on the skull;

the utility model discloses in, still be provided with slidable on the arm that pulls off of brain surgery operation retractor and open board 11 that contracts, still be provided with on the arm fixed plate that pulls off and pull off arm crank 10, through rocking pull off arm crank 10, make the board 11 that contracts slide, can make the brain clamp plate on the arm that pulls off contract or open.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Drawings

The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:

fig. 1 shows a schematic structural view of a retractor for brain surgery according to the present invention; wherein the numbering represents: 1. brain compression plate; 2. a retracting arm; 3. a U-shaped clamping groove; 4. a fixed arm; 5. a horizontal sliding plate; 6. a horizontal fixing bolt; 7. a vertical fixing bolt; 8. a retracting arm fixing plate; 9. a retracting arm rack plate; 10. a hand crank of the arm is pulled open; 11. a retractable plate; 12. a fixer crank; 13. a retainer rack plate; 14. a sliding arm.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention is described with reference to fig. 1:

according to the utility model discloses a specific embodiment, brain surgery operation retractor is earlier when using on the skull reason that exposes after the patient opens the cranium at the card of "U" type draw-in groove 3 on fixed arm 4, then through waveing fixer crank 12, makes sliding arm 14 slide on fixer rack plate 13, treats that "U" type draw-in groove 3 card is fixed firmly with fixer and skull when on the skull reason of the contraposition on sliding arm 14. The retraction plate 11 is then slid by rocking the retraction arm handle 10 to retract the retraction arm 2 to the maximum possible extent.
