Description
Technical Field
[0001] The utility model relates to the technical field of surgical instruments, in particular to an abdominal fat expansion device used in an operating room. Background Art
[0002] Generally speaking, laparotomy is a traditional surgical method, which mainly involves making an incision in the abdomen to complete a series of surgical operations in the abdominal cavity. Laparotomy usually has a larger surgical opening, and the doctor has a better field of vision, which makes it easier to directly and clearly see the patient's symptoms. It can help complete surgical operations with a larger resection range and more complex plans. However, the disadvantages of laparotomy are that the wound is relatively large, the patient suffers obvious pain after the operation, and the recovery is relatively slow, which increases the risk of infection and may leave scars. At the same time, the risk during the operation is relatively large, the amount of bleeding is large, which may bring great pressure to the patient, and may also affect other organs, such as increasing the chance of intestinal adhesion. In order to ensure a good field of vision during the operation, the abdominal fat that has been cut is usually stably supported and fixed by a spreader during the operation to prevent the abdominal incision from affecting the doctor's operation during the operation due to unstable fixation. However, this type of instrument is generally supported by twisting the screw rod to drive the frame to open. In order to ensure the stability of the frame opening, after the adjustment is completed, the rotating end of the screw rod needs to be limited to prevent the incision from being loosened or enlarged during the operation, which may affect the normal operation.

The angle between the support frame 7 is adjusted by the rotational connection between the connecting seat 3 and the support frame 7, and the support hook 9 supports the incision.
[0031] The outer surface of the fixing frame 1 is penetrated by the slide bar 10, and the outer surface of the slide bar 10 is evenly provided with a limiting groove 11, and the end of the slide bar 10 facing the open frame 7 is fixedly provided with a connecting seat 3, the outer surface of the fixing frame 1 is penetrated by the lower end of the limiting plate 12, and the lower end of the limiting plate 12 is connected with the lower surface of the fixing frame 1. The limiting rod 14 is fixedly provided on the outer surface of the upper end of the limiting plate 12, and the limiting rod 14 is vertically arranged downward, and the limiting plate 12 is connected with the limiting groove 11 by the limiting rod 14, and the upper end of the limiting plate 12 is a cross The support block 15 is of a rotatable shape and is mounted on the upper surface of the fixed frame 1 on one side of the limiting plate 12. The thickness of the support block 15 is greater than the length of the limiting rod 14 inserted into the limiting groove 11, and one side of the support block 15 is set with a vertical section, the vertical section of the support block 15 is set toward the limiting plate 12, and the vertical section of the support block 15 is in contact with the outer surface of the limiting plate 12. The angle of the spread frame 7 is limited by engaging the limiting rod 14 with the limiting groove 11 after the spread frame 7 is rotated into place, so as to prevent the spread frame 7 from deforming during the operation and causing changes in the incision.
[0032] Working principle: when using the abdominal fat expansion device for the operating room, first fix the fixing frame 1 above the patient's abdominal incision through the clamp, and then rotate the toggle wheels 5 on both sides at the same time. The toggle wheels 5 rotate relative to the fixing frame 1 through the mounting frame 4 and the guide groove 6. At this time, the displacement rod 2 slides relative to the fixing frame 1 through the threaded connection with the toggle wheel 5, and the displacement rod 2 drives the expansion frame 7 to slide to both sides through the connecting seat 3. During the process, as the angle between the expansion frames 7 changes, the connecting seats 3 on the other two sides of the expansion frame 7 maintain stable sliding with the fixing frame 1 through the sliding rod 10, so that the expansion frame 7 can always be located in the middle of the fixing frame 1. As the expansion frame 7 is opened, the expansion frame 7 contacts the patient's abdominal incision fat through the support hook 9 installed at the lower end of the connecting block 8. The support hooks 9 at different positions rotate when contacting the patient's abdominal incision fat to maintain stable contact between the support hooks 9 and the patient's abdominal incision fat.
[0033] After the expansion frame 7 is moved into place, the support block 15 is rotated so that one end of the cross section of the support block 15 turns to the limit plate 12, and the limit plate 12 slides downward under the pull of the limit spring 13 between the fixed frame 1. At this time, the limit plate 12 is engaged with the limit groove 11 through the limit rod 14, so that the slide bar 10 cannot slide relative to the fixed frame 1. Even if the toggle wheel 5 is accidentally rotated during the operation, the opening degree of the expansion frame 7 will not change, thereby increasing the overall practicality.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
