[0029] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0030] like Figures 1 to 6 As shown, this embodiment designs an operation auxiliary device for surgical wound dilation, including components such as a mounting seat, a support assembly, and a wound dilation assembly.

[0031] The mounting base is a ground support base 1 or a U-shaped clamp 2, so that the mounting base can be fixed to the ground or to the edge of the bed.

[0032] When the mounting base is a ground support base 1, the ground support base 1 includes a vertical pole and a chassis. The lower end of the vertical pole is vertically fixed to the chassis (welded), and the upper end of the vertical pole is used to be inserted into the pipe section 33 of the supporting column 3, and is tightened by the screws on the side wall of the pipe section 33, thereby realizing the connection between the mounting base and the supporting assembly.

[0033] When the mounting seat is a U-shaped clamp 2, the U-shaped clamp 2 includes components such as a U-shaped seat, a tightening block and a tightening screw; the U-shaped seat can be fixed to the outer tube wall of the pipe section 33 by bolts, and the U-shaped mouth of the U-shaped seat is arranged forward to facilitate clamping on the edge of the bed. The tightening screw is threadedly connected to the side wall of the U-shaped seat and is rotatably connected to the tightening block. When the tightening screw is rotated, the lifting and lowering movement of the tightening block can be controlled. The tightening block is arranged in the U-shaped seat. When the tightening block rises, the tightening block can cooperate with the U-shaped seat to clamp the edge of the bed.

[0034] The support assembly includes components such as a transverse arm 4 , an extending rotating arm 5 , and a support column 3 .

[0035] The support column 3 is arranged vertically, and includes a slot section 32 and a pipe section 33. The slot section 32 is connected to the top of the pipe section 33, and the pipe section 33 at the lower end of the support column 3 is fixedly connected to the mounting seat. A lifting screw 31 and a lifting slider 34 are arranged in the slot section 32. The lifting screw 31 is threadedly matched with the lifting slider 34; the pipe section 33 is plugged into the mounting seat, and the upper end of the lifting screw 31 extends out of the slot section 32. When the lifting screw 31 is manually rotated, the height position of the lifting slider 34 can be adjusted. The horizontal arm 4 is arranged horizontally and can be lifted and lowered to the front side of the support column 3; the rear end of the horizontal arm 4 is fixedly connected to the lifting slider 34 by screws, so that when the lifting slider 34 is lifted and lowered vertically, the horizontal arm 4 can also be lifted and lowered vertically.

[0036] The extending rotating arm 5 is connected to the transverse arm 4 in a forward and backward sliding manner. The transverse arm 4 is in a groove shape. A forward and backward adjusting screw rod 41 and a forward and backward sliding block 42 are arranged in the groove of the transverse arm 4. The rear end of the transverse arm 4 is fixedly connected to the lifting sliding block 34 by screws. The front end of the forward and backward adjusting screw rod 41 extends from the front end of the transverse arm 4. When the forward and backward adjusting screw rod 41 rotates, the forward and backward sliding block 42 can change its forward and backward position under the adjustment of the forward and backward adjusting screw rod 41, thereby realizing the adjustment of the forward and backward position of the extending rotating arm 5.

[0037] The extending rotating arm 5 comprises a front connecting seat 51, a front rotating arm 52, a locking nail, a middle rotating arm 54, a rear arm seat 55, a rear connecting seat 57 and a tensioning nail 56. The front end of the front connecting seat 51 is provided with a connecting ear, so as to fix the front end of the front connecting seat 51 with the opening frame rod 6 of the wound opening assembly. The rear end of the front connecting seat 51 is rotatably connected with the front rotating arm 52, and the rotating shaft between the two is arranged along the left and right direction. The rear end of the front connecting seat 51 is U-shaped, and the front end of the front rotating arm 52 is inserted into the U-shaped notch and passed through by the rotating shaft; a rotatable locking bolt 53 is arranged at the center of the rotating shaft, and a nut is connected to the end of the locking bolt 53 away from the nut, and the nut is embedded in the front rotating seat. When the locking bolt 53 is tightened, the rear end of the front connecting seat 51 can be pulled closer and the front end of the front rotating arm 52 can be clamped to achieve the fixing of the relative rotation position of the front connecting seat 51 and the front rotating arm 52. The rear end of the front rotating arm 52 is rotatably connected to the middle rotating arm 54, and the rotating shaft between the two is arranged in the up-down direction, so that the rotating shaft between the front connecting seat 51 and the front rotating arm 52 is perpendicular to the rotating shaft between the front rotating arm 52 and the middle rotating arm 54, and the rear end of the front rotating arm 52 is U-shaped, and the front end of the middle rotating arm 54 is inserted into the notch of the U-shaped and passed through by another rotating shaft; a rotatable locking bolt 53 is also arranged at the center of the rotating shaft, and a nut is connected to the end of the locking bolt 53 away from the nut, and the nut is embedded in the front rotating arm 52. When the locking bolt 53 is tightened, the rear end of the front rotating arm 52 can be pulled closer and the front end of the middle rotating arm 54 can be clamped to achieve the fixing of the relative rotation position of the front rotating arm 52 and the middle rotating arm 54. Both rotating shafts are locked by the locking bolt 53. The rear end of the middle rotating arm 54 is rotatably plugged with the rear arm seat 55. The front end of the rear arm seat 55 is provided with a circular plug hole. The circular plug joint of the middle rotating arm 54 can be inserted into the circular plug hole and rotated around the axis of the middle rotating arm 54. The tightening nail 56 passes through the rear arm seat 55 and is threadedly connected with the middle rotating arm 54. When the tightening nail 56 is tightened, the friction between the rear arm seat 55 and the bracket of the middle rotating arm 54 can be increased, thereby achieving relative fixation of the positions of the two. The rear arm seat 55 is fixedly connected to the front and rear sliders 42 through the rear connecting seat 57. The rear connecting seat 57 adopts an I-shaped structure so as to be connected to the rear arm seat 55 and the front and rear sliders 42 by screws.

The pull claw 9 and the push claw 10 are disposable plastic parts supported by non-toxic plastic, which are convenient for replacement and wound protection.

[0040] The pulling claw 9 is L-shaped, and the hook end at the lower end of the vertical part of the pulling claw 9 is bent backward to improve the pulling stability of the wound. The horizontal part of the pulling claw 9 is tubular and plugged with the middle bracket 8. A locking claw screw 11 for pressing against the side bracket 7 is arranged on the tube wall of the horizontal part of the pulling claw 9. After the front and rear positions of the pulling claw 9 are adjusted, the locking claw screw 11 can be used to fix it, so as to ensure that the pulling claw 9 pulls the wound backward. The pushing claw 10 is L-shaped, and the hook end at the lower end of the vertical part of the pushing claw 10 is bent forward to improve the stability of pushing the wound. The horizontal part of the pushing claw 10 is tubular and plugged with the side bracket 7. A locking claw screw 11 for pressing against the side bracket 7 is arranged on the tube wall of the horizontal part of the pushing claw 10. After the front and rear positions of the pushing claw 10 are adjusted, the locking claw screw 11 can be used to fix it, so as to ensure that the pushing claw 10 pushes the wound forward. When using the pulling claw 9 and the pushing claw 10, the hook ends of the pulling claw 9 and the pushing claw 10 are inserted into the wound, and then the front and rear positions of the pulling claw 9 and the pushing claw 10 are adjusted, and then locked with the locking claw screw 11. The pulling claw 9 and the two pushing claws 10 form a three-point support for the wound, which is beneficial to increase the width of the wound and facilitates the doctor to treat the affected area in the wound.

[0041] A T-slot is provided on the front side of the support rod 6, and the rear ends of the side bracket 7 and the middle bracket 8 are slidably connected in the T-slot to facilitate adjustment of the positions of the side bracket 7 and the middle bracket 8; the rear ends of the side bracket 7 and the middle bracket 8 are threadedly connected with a locking screw, which can lock the bottom of the T-slot to achieve positioning of the side bracket 7 and the middle bracket 8.

[0042] The front part of the middle bracket 8 is rod-shaped and arranged along the front-back direction, and the rear part of the middle bracket 8 is slidably connected in the T-shaped groove and is provided with a tightening screw.

[0043] The side bracket 7 includes a claw arm 71, an adjustment pin 72, a rotation shaft 73, a side bracket seat 74 and an adjustment seat 75; the side bracket seat 74 is slidably connected in the T-slot and is provided with a tightening screw; the claw arm 71 is a straight rod arranged in the front-back direction, a rotatable rotation shaft 73 is arranged in the middle of the claw arm 71, the rear end of the claw arm 71 is rotationally connected to one side of the side bracket seat 74, and the front end of the claw arm 71 is used to connect the push claw 10; the adjustment seat 75 is rotationally connected to the other side of the side bracket seat 74, the adjustment pin 72 vertically passes through the middle of the rotation shaft 73 and is rotationally connected to the adjustment seat 75, and the adjustment pin 72 is threadedly connected to the rotation shaft 73. When the adjustment pin 72 is manually rotated, the swing of the claw arm 71 in the left and right directions can be controlled, so as to realize the control of the position of the push claw 10. During the operation, when treating different positions in the wound, the shape of the wound opened by the wound opening assembly can be changed by adjusting the position of the push claw 10, so as to facilitate the treatment of the wound.

[0044] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
