Detailed Description
The specific structure of the present invention is described in detail with reference to fig. 1 to 5. The pneumoperitoneum-free laparoscopic abdominal retractor comprises a fixed support 1 consisting of vertical columns 2, wherein lifting cross beams 3 are movably arranged on the vertical columns 2 of the fixed support 1, and positioning slide blocks 4 are movably arranged on the lifting cross beams 3. The lower part of the position adjusting slide block 4 is provided with a hanging connecting rope 5 for hanging the traction support frame 7, and the lower end of the hanging connecting rope 5 is connected with a hanging ring 6 at the upper end of a gripping handle 8 of the traction support frame 7. And then utilize the lift on vertical stand 2 of lifting beam 3, adjust the height of pulling support frame 7 to through the lateral shifting and the location of positioning slider 4 on lifting beam 3, come the corresponding position of adjustment to pull support frame 7, make things convenient for the use of device.
The traction support frame 7 arranged below the positioning slide block 4 of the lifting beam 3 of the fixed support 1 is composed of a vertically arranged holding handle 8, and a rotating rod 10 capable of freely rotating is arranged in a through hole in the middle of the holding handle 8. The rotary rod 10 is positioned at the upper end of the outer side of the upper part of the holding handle 8, and a butterfly-shaped handle 9 for rotating the rotary rod 10 is arranged; the lower end of the rotating rod 10, which is located at the outer side of the lower portion of the grip handle 8, is provided with a lower bending claw 14. The lower bending claw 14 is composed of a horizontal section and a lower bending section, and the horizontal section of the lower bending claw 14 is fixedly connected with the lower end of the rotating rod 10. An upper bending claw 12 is arranged above the lower bending claw 14, the upper bending claw 12 is composed of a horizontal section and a lower bending section, and the horizontal section of the upper bending claw 12 is rotatably connected with the lower end of the rotating rod 10. And, four middle bending claws 13 are arranged between the upper bending claw 12 and the lower bending claw 14 in sequence along the vertical direction, the middle bending claw 13 is also composed of a horizontal section and a lower bending section, and the horizontal section of each middle bending claw 13 is respectively connected with the lower end of the rotating rod 10 in a rotating way.
The upper bending claw 12 of the traction support frame 7 is connected with the adjacent middle bending claw 13, the two adjacent middle bending claws 13 and the lower bending claw 14 is connected with the adjacent middle bending claw 13 through a limit pull rope 16. Therefore, the butterfly-shaped handle 9 is used for driving the rotating rod 10 and the lower bending claw 14 at the lower end of the rotating rod to rotate together, and the middle bending claws 13 are pulled to be sequentially unfolded through the limiting pull ropes 16, so that an umbrella-shaped unfolding structure of the traction support frame 7 is formed, and sufficient operation space and visual field are provided for laparoscopic surgery. In order to improve the use reliability of the device, a locking nut 11 for locking the position of the rotating rod 10 is arranged between the lower end of the holding handle 8 and the lower part of the rotating rod 10 rotatably arranged in the middle of the holding handle 8, so that the rotating rod 10 is locked by the locking nut 11 to prevent the bending claw from rotating.
A return baffle 15 which is vertically and upwards arranged is arranged at the side part of the horizontal section of the lower bending claw 14; therefore, in the process that the lower bending hook claws 14 rotate reversely along with the rotating rod 10, the return baffle plates 15 are used for withdrawing the middle bending hook claws 13, so that the umbrella-shaped structure of the traction support frame 7 is folded, and the traction support frame 7 can be conveniently put into or taken out of the abdominal wall incision of a patient. Meanwhile, an auxiliary positioning rod 17 which is vertically and upwardly arranged is further arranged on the horizontal section of the upper bending hook claw 12 and on the upper side close to one end of the rotating rod 10, so that the position of the upper bending hook claw 12 can be adjusted in an auxiliary manner in the process of unfolding and folding the umbrella-shaped structure of the traction support frame 7.
When the gasless laparoscope abdominal retractor is used, firstly, an incision is made in the middle of the upper abdomen on the umbilicus, and the length is about 2 cm; and the position of the traction support frame 7 is correspondingly adjusted by the transverse movement and the positioning of the positioning slide block 4 on the lifting beam 3 according to the specific position of the abdominal wall incision. Then, the traction support frame 7 with the bending hook claws folded (stacked) together is placed in the abdominal cavity, the holding handle 8 is held and lifted slightly, then the butterfly-shaped handle 9 is used for driving the rotating rod 10 and the lower bending hook claw 14 at the lower end of the rotating rod to rotate slowly, and the middle bending hook claws 13 are pulled by the limit pull ropes 16 to be unfolded sequentially to form an umbrella-shaped unfolding structure of the traction support frame 7; and, confirm that there is no clamping abdominal cavity content, expand to around a week completely, and then lock the rotating rod 10 by the lock nut 11, prevent the convolution of the bending hook claw; meanwhile, the height of the traction support frame 7 is adjusted by lifting the lifting cross beam 3 on the vertical upright post 2, so that sufficient operation space and visual field are provided for laparoscopic surgery. After the operation is finished, the rotating rod 10 is rotated reversely, and in the process that the lower bending claw 14 rotates reversely along with the rotating rod 10, the return baffle 15 is utilized to return each middle bending claw 13, so that the umbrella-shaped structure of the traction support frame 7 is folded; subsequently, the traction brace 7 is removed from the abdominal wall incision of the patient.
