Example 1

As shown in fig. 1 to 5, the present embodiment provides an abdominal retractor, which includes a retractor body 100, wherein the retractor body 100 includes a fixed retractor 110 and movable retractors 120 disposed at front and rear sides of the fixed retractor 110; the fixed drag hook 110 comprises a drag hook head 111, a drag hook tail 113 and a screw rod 112 arranged between the drag hook head 111 and the drag hook tail 113, and the movable drag hook 120 comprises a drag hook part 121 and a connecting part 122; all be equipped with connecting rod 130 between drag hook head 111 and the movable drag hook 120 that corresponds, the both ends of connecting rod 130 articulate respectively on drag hook head 111 and connecting portion 122, the right-hand member portion of connecting portion 122 all articulates on the front and back both ends of a movable block 140 correspondingly, lead screw 112 passes movable block 140 and sets up, be equipped with the cross-section on the right flank of movable block 140 with lead screw 112 coaxial and be the first spout 311 of T type and be the annular, the threaded sleeve is equipped with first rotating ring 150 on the lead screw 112, be equipped with the first slide rail 321 with first spout 311 matched with on the left end face of first rotating ring 150.

Through the structure in the embodiment, the abdominal cavity retractor is in the operation process, the drag hook tail part 113 is fixed on the frame around the operation table, so that the abdominal cavity retractor is fixed, manual pulling is not needed, the abdominal cavity drag hook is prevented from moving in the operation process, and the operation is safer and more convenient. The first slide rail 321 is installed in the first slide groove 311, so that the first rotating ring 150 is connected with the moving block 140, and meanwhile, the first rotating ring 150 can rotate, and due to the threaded fit between the first rotating ring 150 and the lead screw 112, the moving block 140 can be driven to move along the lead screw 112 when the first rotating ring 150 rotates; the right end of the movable draw hook 120 is hinged to the moving block 140, and two ends of the connecting rod 130 are hinged to the draw hook head 111 and the movable draw hook 120 respectively, so that when the moving block 140 moves along the lead screw 112, the angle between the movable draw hook 120 and the fixed draw hook 110 can be changed, the width of the abdominal cavity retractor can be adjusted, and the operation is convenient.

In this embodiment, a movable cavity 411 into which the screw rod 112 extends is disposed in the tail portion 113 of the retractor, a second sliding groove 421 having a T-shaped and circular cross section is disposed on the left side surface of the tail portion 113 of the retractor and coaxial with the screw rod 112, a second rotating ring 160 is screwed on the screw rod 112, and a second sliding rail 431 matched with the second sliding groove 421 is disposed on the right end surface of the second rotating ring 160.

Through the structure in this embodiment, the second slide rail 431 is installed in the second chute 421, so that the second rotating ring 160 can rotate while the second rotating ring 160 is connected with the tail 113 of the retractor, because the second rotating ring 160 is in threaded fit with the lead screw 112, the second rotating ring 160 can rotate to enable the lead screw 112 to stretch in the movable cavity 411, so that the second rotating ring 160 can be rotated to adjust the length of the lead screw 112 extending out of the movable cavity 411, the whole length of the abdominal cavity retractor can be adjusted, and the abdominal cavity retractor can be conveniently used in practice.

In this embodiment, the inner side wall of the movable cavity 411 is relatively provided with a limiting chute 412; the side of the screw rod 112 extending into the movable cavity 411 is provided with a limit post 441 corresponding to the limit sliding groove 412.

Through the arrangement of the limiting sliding groove 412 and the limiting column 441 in the embodiment, the limiting sliding groove 412 can limit the limiting column 441, so that the second rotating ring 160 is effectively prevented from rotating to drive the screw rod 112 to be separated from the drag hook tail 113, and the abdominal cavity retractor cannot work.

In this embodiment, the retractor head 111 and the retractor portion 121 are both provided with a movable chamber 511 with an opening facing downward, and a rotatable rotating rod 520 with one end extending above the retractor head 111 or the retractor portion 121 is arranged in the movable chamber 511; an extension plate 530 moving up and down is arranged in the moving cavity 511, and a threaded hole 531 for the rotating rod 520 to extend into and to be in threaded fit with the rotating rod 520 is arranged on the extension plate 530.

Through the above-mentioned structure in this embodiment, because dwang 520 and screw hole 531 screw-thread fit and dwang 520 can rotate, it can restrict the extension board 530 that is the square body form to remove the chamber 511 simultaneously, make extension board 530 can't be at the internal rotation of removal chamber 511, make dwang 520 rotate and to drive extension board 530 and go up and down in removing chamber 511, make drag hook head 111 and drag hook portion 121 and abdominal cavity incision lateral wall matched with length can adjust, the needs when satisfying different size patients and performing the operation are easy operation convenience simultaneously.

In this embodiment, the front and rear side walls of the moving chamber 511 are provided with sliding grooves 171 along the vertical direction, and the end surface of the extending plate 530 is provided with sliding posts 172 corresponding to the sliding grooves 171 and sliding in the sliding grooves 171.

Through the arrangement of the sliding groove 171 and the sliding column 172 in the embodiment, the sliding groove 171 limits the sliding column 172, so that the length of the hook head 111 and the hook portion 121 matched with the side wall of the abdominal incision can not be adjusted by effectively preventing the rotating rod 520 from rotating to drive the extending plate 530 to be separated from the moving cavity 511.

In this embodiment, the sides of the retractor head 111 corresponding to the connecting portion 122 are provided with hinge grooves 181 for the two ends of the connecting rod 130 to extend into, and the upper and lower sides of the hinge grooves 181 are provided with hinge holes 182; the side of the connecting rod 130 is provided with a hinge post 131 positioned in the corresponding hinge hole 182.

Through the arrangement of the hinge slot 181, the hinge hole 182 and the hinge column 131 in the embodiment, the hinge column 131 is located in the hinge hole 182, so that the connecting rod 130 can be preferably connected to the hook head 111 and the connecting part 121 in a hinged manner, and the structure of the abdominal cavity retractor is more compact.

When the abdominal cavity retractor is used specifically, the tail portions 113 of the hooks are fixed on the operating table frame, according to the needs of the surgery, the first rotating ring 150 is rotated to drive the moving block 140 to move along the screw rod 112 to adjust the angle between the movable hook 120 and the fixed hook 110, and the second rotating ring 160 is rotated to enable the screw rod 112 to be capable of stretching and adjusting the length of the whole abdominal cavity retractor in the movable cavity 411, so that the hooks are attached to the abdominal wall of the abdominal cavity incision, and the needs of the surgery are met; when the subcutaneous fat of the patient is more and the abdominal wall thickness is larger, the rotating rod 520 is rotated to extend the extending plate 530, so that each draw hook is preferably attached to the abdominal wall of the abdominal incision, and the operation is effectively ensured.

In short, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the scope of the present invention.
