Preferably, the pulling-open mechanism 5 is composed of hydraulic cylinders 501 at two sides of the middle of the pulling-open mechanism 5, piston rods 502 at the front and the back of the hydraulic cylinders 501, a connecting column 504 at the front of the piston rod 502, a lapping plate 503 at one side of the hydraulic cylinders 501, a control circuit board 505 inside the connecting column 504, a pulling hook plate 507 at the bottom end of the connecting column 504 and a bolt 508 in the middle of the pulling hook plate 507, when a user aligns the pulling-open mechanism 5 with the wound of the user, the user hooks the two pulling hook plates 507 to two ends of the wound respectively, and then presses a button on the right side of the front of the pulling-open mechanism 5 (after releasing, the piston rod 502 stops extending, and the piston rod 502 can be retracted by the button on the left side of the front), so that the hydraulic cylinders 501 at two sides controlled by the control circuit board 505 extend the piston rods 502 at the front and back ends, and the piston rods 502 are fixed with the connecting column 504, so that the fixed connecting column 504 can be extended together when the piston rods 502 are extended, when the corresponding connecting column 504 extends out, the pulling hook plate 507 at the bottom end is driven to move together, the wound is pulled back and forth by the two pulling hook plates 507, so that the wound is exposed, the middle of the pulling mechanism 5 is hollow, a user can operate the exposed wound through the pulling mechanism 5, when the pulling mechanism 5 is used up, the user can unscrew the pulling mechanism 5 through the clamping pins at the lapping plate 503 and the inner column 402, when the clamping pins of the lapping plates 503 at the two sides are unscrewed, the user can take the pulling mechanism 5 out of the telescopic rod 4 for cleaning, meanwhile, the user can rotate the bolt 508 anticlockwise, so that the pulling hook plate 507 is taken out from the connecting column 504 under the driving of the bolt 508, then the user can also independently clean and sterilize the pulling hook plate 507, and the pulling setting of the pulling mechanism 5 is controlled by the control circuit board 505, therefore, the pulled wound can be kept in a size for a long time under the control circuit board 505, and the situation that the wound is easy to retract due to manual pulling by using the draw hook is avoided, so that the practicability of the whole surgical instrument 1 is greatly improved.

The working principle is as follows:

firstly, because the bottom and the top of the supporting cylinder 2 are consistent in size, the bottom of the supporting cylinder 2 can be in small contact area when being attached to the ground, and the supporting cylinder cannot be supported, the supporting cylinder 2 is provided with the bottom plate 6 and the anti-skid grains 7, the bottom plate 6 is larger than the bottom of the supporting cylinder 2, so that the contact area between the bottom of the supporting cylinder 2 and the ground is increased, meanwhile, the bottom plate 6 is also provided with the uneven anti-skid grains 7, and the anti-skid grains 7 can increase the friction and the anti-skid performance between the bottom plate 6 and the ground, so that the bottom plate 6 can better support the supporting cylinder 2;

then, when the user wants to use the whole surgical instrument 1, the user firstly aligns the pulling-open mechanism 5 with the surgical position, so the user can firstly drive the telescopic rod 4 to move upwards from the supporting cylinder 2 by the supporting rod 3, the bottom of the telescopic rod 4 is directly close to the top of a patient on the bed, then the supporting rod 3 is screwed clockwise by the bayonet lock penetrating through the hole of the supporting cylinder 2, when the heights of the supporting rods 3 on the two sides are consistent, the user then releases the bayonet lock of the telescopic rod 4 anticlockwise, then pulls open the two sides of the supporting rod 3, so that the inner column 402 and the sleeve 405 of the telescopic rod 4 are both taken out, then holds the supporting cylinder 2 to be respectively placed on the empty space on the two sides of the wound of the patient, then holds the pulling-open mechanism 5 to move to the top of the wound of the patient, and then holds the bayonet lock by the user to fix the lengths of the telescopic rod 4 adjusted on the two sides, then, the user can use the pulling-opening mechanism 5, so that the setting of the adjusting mechanism is convenient for the user to position and align the wound of the pulling-opening mechanism 5 better, and the pulling-opening mechanism 5 can position and support for a long time due to the support of the supporting cylinder 2, and meanwhile, the position of the pulling-opening mechanism 5 can be adjusted, so that the user can use the pulling-opening mechanism 5 through the wounds of different parts of the patient conveniently by adjusting the position of the pulling-opening mechanism 5, and the use range of the whole surgical instrument 1 is greatly improved;

then, the support rods 3 on both sides are provided with the scales 8, and the positions of the scales 8 arranged on the support rods 3 on both sides are opposite, so that when a user adjusts the height of the support rods 3 moving upwards from the support cylinder 2, the user can know the adjusted height through the scales 8, and the user can conveniently move the support rods 3 on both sides to the same height through the scales 8, thereby avoiding the condition that the heights of the support rods 3 on both sides are uneven due to the fact that the user moves along with the user;

next, the telescopic rod 4 is composed of a telescopic cylinder 401, two sleeves 405 and an inner column 402, and the same positions of the tops of the telescopic cylinder 401, the sleeves 405 and the inner column 402 are all provided with fixing holes 404, the fixing holes 404 facilitate users to screw the bayonet lock clockwise to fix, if only the inner column 402 moves out, the bayonet lock can pass through the fixing holes 404 of the telescopic cylinder 401 and the sleeves 405 to screw and fix the inner column 402, if the sleeve 405 similar to the inner column 402 is also taken out, the bayonet lock can be screwed to the inner column 402 through the fixing hole 404 of the sleeve 405, and then another bayonet lock is penetrated through the fixing holes 404 of the telescopic cylinder 401 and the other sleeve 405 to screw and fix the sleeve 405, so that the setting of the fixing holes 404 is convenient for the telescopic rod 4 to be fixed under different lengths, and the situation that the telescopic rod 4 is displaced due to no fixing place is provided;

finally, after the user aligns the opening mechanism 5 with the wound of the user, the user hooks the two hook plates 507 to the two ends of the wound respectively, and then presses the right button on the front side of the opening mechanism 5 (after the piston rod 502 stops extending, the piston rod 502 can be retracted by the left button on the front side), so that the hydraulic cylinders 501 on the two sides are controlled by the control circuit board 505 to extend the piston rods 502 on the front and rear ends, and the piston rods 502 are fixed with the connecting columns 504, so that the fixed connecting columns 504 can be driven to extend together when the piston rods 502 extend, the hook plates 507 at the bottom end can be driven to move together when the corresponding connecting columns 504 extend, the wound can be pulled back and forth by the two hook plates 507, so that the wound is exposed, and the middle of the opening mechanism 5 is hollow, so that the user can operate the exposed wound through the opening mechanism 5, when the pull-off mechanism 5 is used up, the user may unscrew the pull-off mechanism 5 by the lap plate 503 and the detent at the inner post 402, when the clamping pins of the lapping plates 503 on the two sides are loosened by rotation, the user can take the pulling-open mechanism 5 out of the telescopic rod 4 for cleaning, meanwhile, a user can rotate the bolt 508 anticlockwise to enable the pull hook plate 507 to be taken down from the connecting column 504 under the driving of the bolt 508, and then the user can carry out independent cleaning and disinfection on the pull hook plate 507, the pulling arrangement of the pulling-open mechanism 5 is controlled by the control circuit board 505, so that the pulled wound can be kept in a size for a long time under the control circuit board 505, the situation that the wound is easy to retract due to manual pulling by using a pulling hook is avoided, thereby greatly improving the practicability of the whole surgical instrument 1, which is the working principle of the improved orthopedic clinical surgical instrument.
