In order to ensure that the draw hook 8 extends into the vagina, the second motor 18 of the pitching angle adjusting mechanism is started, the second motor 18 drives the screw rod 15 to rotate, the screw rod 15 rotates to drive the nut 16 to move relative to the screw rod 15, and the nut 16 moves to drive the supporting rod 17 to push the supporting plate 14 to rotate relative to the base 13. In order to ensure that the draw hook 8 is attached to the interior of the vagina, the first motor 11 is started, the first motor 11 pulls the draw hook 8 to rotate relative to the cylinder 7 through the rope body 12, and the draw hook 8 rotates to the interior of the vagina to be attached to the vagina.
At the moment, the third motor 24 of the first sliding mechanism is started reversely, the first sliding mechanism drives the pulling mechanisms to move outwards along the center, at the moment, the third motor 24 is started reversely, the third motor 24 drives the gear 22 to rotate through the second rotating shaft 23, the gear 22 rotates to drive the rack 21 and the sliding rod 4 to synchronously slide relative to the loop bar 3, at the moment, the hook assemblies of the pulling mechanisms move inwards along the center, the hooks of the pulling mechanisms synchronously pull the private parts of patients to move along all directions, the pressure sensor 5 is used for monitoring the pressure during pulling, when the pressure is different, numerical values are fed back to the microprocessor 6, and the microprocessor 6 controls and independently adjusts each pulling mechanism.
When the middle operation space of the main doctor is insufficient, the relative movement mechanism is started to drive the two semi-annular plate bodies to move relatively, namely, the fourth motor 31 is started, the fourth motor 31 drives the left-handed screw 25 and the right-handed screw 26 to rotate synchronously, the left-handed screw 25 drives the left-handed nut 27 and the first connecting rod 29 to move synchronously, the right-handed screw 26 drives the right-handed nut 28 and the second connecting rod 30 to move through movement, namely, the two semi-annular plate bodies 21 are driven to move relatively, the opening in the middle of the private part of the patient is enlarged, and a larger operation space is provided for the main doctor.
The height of the invention can be adjusted, the supporting seat 1 can be adjusted to a proper height according to different conditions of each person, when the height is adjusted, the telescopic piece 34 is started, the telescopic end of the telescopic piece 34 extends upwards and retracts to drive the supporting seat 1 and a plurality of pulling mechanisms fixed on the supporting seat 1 to lift synchronously, and the second sliding block 35 and the second sliding groove 36 can be used for guiding in a matching way in the lifting process.
In summary, the invention provides a surgical retractor for gynecological surgery, which can utilize a plurality of pulling mechanisms to pull the private parts of patients from all directions, so as to ensure that all positions of the private parts are uniformly stressed, and the problem that the local injury of the patients due to uneven stress on one side can not occur.
