[0002] General surgery is a surgical discipline involving various organs of the human body, covering a variety of diseases and surgical treatment methods. In the development history of general surgery, with the continuous advancement of medical technology, the scope and methods of general surgery have also been continuously expanded and improved. The development of general surgery can be traced back to ancient times. At that time, doctors mainly performed surgical operations to treat trauma and trauma. With the development of anatomy and in-depth understanding of the structure of the human body, surgery has gradually become a more systematic and scientific treatment method. The development of general surgery has made great progress in the 20th century, especially in anesthesia technology, disinfection measures and surgical instruments. Advances have provided a solid foundation for the safety and effectiveness of general surgery. General surgery involves multiple organs and systems, including the digestive system, internal system, thoracic cardiovascular system and urogenital system. The types and purposes of surgery vary, and can be diagnostic surgery, disease treatment surgery, functional surgery and reconstructive surgery. When general surgery is water-treated, it will need to use many surgical instruments according to different surgical needs, such as retractor-type components, which are needed to assist the normal operation of the surgery.
[0003] Most of the elliptical hook devices currently on the market have the following problems when in use:
[0004] When a traditional elliptical hook device is actually used, the hook device is adjusted according to the size of the pull, and the hook device itself does not have a limiting structure, which causes the hook device to shake left and right when adjusted, and the hook head shakes at the same time, resulting in instability during adjustment, which increases the difficulty of adjustment; when a traditional elliptical hook device is actually used, the hook head and the hook device are usually installed and fixed by direct welding. As the use time continues to increase, it is difficult to remove the hook head, and the hook head is cleaned or replaced, which increases the difficulty of installation and disassembly.

[0027] When the hook housing 3 needs to be pulled and adjusted, the slider 15 can slide inside the slide groove 7, and the limit plates 6 on both sides can achieve the limiting function, thereby avoiding the situation where the hook device itself does not have a limiting structure, resulting in the hook device shaking left and right when adjusting. After the adjustment is completed, the limit column 9 is inserted into the limit hole 11 to fix the adjusted position, which can improve stability during adjustment and reduce the difficulty of adjustment.
[0028] The top of the retractor shell 3 is fixedly connected to the fixing block 12, and the handle 2 is docked on the outside of the retractor shell 3. The fixing block 12 is clamped at the top and bottom of the handle 2. Medical staff can operate and use the retractor shell 3. As the use time increases, the fixing rod 14 can be pulled out to separate the fixing rod 14 from the fixing socket 16, and the fixing block 12 from the handle 2. The handle 2 shell can be removed separately for cleaning or replacement. During installation, the fixing block 12 is attached to the top and bottom of the handle 2, and the fixing rod 14 is inserted into the inside of the fixing socket 16, thereby reducing the difficulty of installation and disassembly.
[0029] A slide groove 7 is provided inside the limiting plate 6, and sliders 15 are connected to both sides of the outer wall of the handle 2. The sliders 15 are movably connected to the inside of the slide groove 7. When the hook housing 3 is adjusted, the sliders 15 simultaneously slide inside the slide groove 7, thereby playing a limiting role.
[0030] The fixing block 12 and the handle 2 both have fixing sockets 16, the fixing sockets 16 are connected to the fixing rods 14 by insertion, the top of the fixing rods 14 are connected to the limiting rings 13, and the limiting rings 13 are attached to the top of the fixing block 12. When the handle 2 and the hook housing 3 are docked together, the fixing rods 14 are inserted into the fixing sockets 16, so that the handle 2 and the hook housing 3 can be installed and fixed together.
[0031] The limiting holes 11 are evenly distributed, and the limiting holes 11 and the limiting columns 9 are both circular. The top of the telescopic frame 5 is fixedly connected to the handle 10. When the limiting column 9 is pulled away, the medical staff can hold the handle 10 to facilitate pulling out or fixing the limiting column 9.
[0032] The handle 2 and the hook housing 3 are both located at the top of the device ring 1 , and the fixing blocks 12 are symmetrically distributed. The fixing blocks 12 are square in shape, and the bidirectional fixing blocks 12 are attached to the top and bottom of the handle 2 , which can limit the handle 2 .

The limit plates 6 on both sides can achieve the limiting function, avoiding the hook device itself not having a limiting structure, resulting in the hook device shaking left and right when adjusting. After the adjustment is completed, the limit column 9 is inserted into the limit hole 11 to fix the adjusted position. As the use time continues to increase, the fixed rod 14 can be pulled out, so that the fixed rod 14 is separated from the fixed socket 16, and the fixed block 12 is separated from the handle 2, so that the handle 2 shell can be removed separately for cleaning or replacement. When installing, the fixed block 12 is attached to the top and bottom of the handle 2, and the fixed rod 14 is inserted into the fixed socket 16, thereby reducing the difficulty of installation and disassembly.
[0034] The utility model comprises: 1. a device ring; 2. a handle; 3. a hook housing; 4. a support block; 5. a telescopic frame; 6. a limit plate; 7. a slide groove; 8. a support rod; 9. a limit column; 10. a handle; 11. a limit hole; 12. a fixing block; 13. a limit ring; 14. a fixing plug rod; 15. a slider; 16. a fixing plug hole. All the components are universal standard parts or components known to those skilled in the art. The structure and principle thereof can be known to those skilled in the art through technical manuals or conventional experimental methods. The utility model solves the problem that the traditional elliptical hook device is difficult to be used in practice. In actual use, the hook device is adjusted according to the required pulling size, but the hook device itself does not have a limiting structure, which causes the hook device to shake left and right when adjusting, and the hook head shakes at the same time, which makes it unstable during adjustment, increasing the difficulty of adjustment; in actual use of traditional elliptical hook devices, the hook head and the hook device are usually installed and fixed by direct welding. As the use time increases, it is difficult to disassemble the hook head, and clean or replace the hook head, which increases the difficulty of installation and disassembly. The utility model combines the above-mentioned components with each other, by providing a limit plate on the top of the device ring, a slider on the outside of the handle, and a slide groove inside the limit plate. When the hook shell needs to be pulled and adjusted, the slider can slide inside the slide groove, and the limit plates on both sides can achieve the limiting function, thereby avoiding the phenomenon that the hook device itself does not have a limiting structure, resulting in the hook device shaking left and right when adjusting. After the adjustment is completed, the limit column is inserted into the limit hole to fix the adjusted position, which can improve stability during adjustment and reduce the adjustment time. The hook shell is provided with a fixing block at the top and bottom, a fixing socket is opened inside the fixing block, and a fixing rod is connected inside the fixing socket. The medical staff can operate and use the hook shell. As the use time increases, the fixing rod can be pulled out to separate the fixing rod from the fixing socket, and the fixing block from the handle. The handle shell can be removed separately for cleaning or replacement. During installation, the fixing block is attached to the top and bottom of the handle, and the fixing rod is inserted into the fixing socket, thereby reducing the difficulty of installation and disassembly.
