[0032] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figures 1-8 As shown, this embodiment of the invention provides a limiting and dilating device for gynecological tumor surgical areas, including a telescopic shell 1. A telescopic rod 4 is slidably connected to the inner cavity of the telescopic shell 1. A first clamping plate 5 is fixedly installed on the right side of the telescopic shell 1, and a second clamping plate 6 is provided on the right side of the first clamping plate 5. Connecting bolts 7 are threadedly connected to the surfaces of the first clamping plate 5 and the second clamping plate 6, and nuts 8 are threadedly connected to the surfaces of the connecting bolts 7. Positioning holes 9 are provided on the top of the telescopic shell 1. A dilating assembly 2 is provided on the left side of the telescopic rod 4. The dilating assembly 2 includes a mounting bracket 201, which is fixedly installed on the telescopic rod 4. On the left side, a knob 202 is movably connected to the front side of the mounting bracket 201. A screw 203 is fixedly connected to the rear side of the knob 202. A screw block 204 is threaded onto the surface of the screw 203. A movable bracket 205 is fixedly installed on both the left and right sides of the screw block 204. A connecting rod 206 is movably connected to the outer side of the movable bracket 205. A movable block 207 is movably connected to the other end of the connecting rod 206. A mounting rod 208 is fixedly installed on the rear side of the movable block 207. A support plate 209 is fixedly installed on the other end of the mounting rod 208. A slot 210 is opened on both the left and right sides of the surface of the mounting bracket 201.

[0036] The top of the telescopic rod 4 is provided with a positioning component 3, which includes a housing 301. The housing 301 is fixedly installed on the top of the telescopic rod 4. Displacement blocks 302 are provided on both the front and rear sides of the inner cavity of the housing 301. A spring 303 is fixedly connected to the inner side of the displacement block 302. A pressing block 304 is fixedly installed on the top of the displacement block 302. A movable rod 305 is movably connected to the bottom of the displacement block 302. A lifting plate 306 is movably connected to the other end of the movable rod 305. Positioning inserts 307 are provided on both the front and rear sides of the bottom of the lifting plate 306.

[0037] By setting up the spreading component 2, the screw block 204 can be moved forward by rotating the knob 202. Then, through the cooperation of the connecting rod 206, the support plate 209 can spread the muscle tissue of the surgical area, thus facilitating the operator to perform subsequent surgical work on the surgical area. At the same time, the mounting frame 201 and the support plate 209 are not in the same vertical direction, so the observation of the surgical area will not be affected by the obstruction of the mounting frame 201. By setting up the positioning component 3, through the tension of the spring 303, the displacement block 302 can cooperate with the movable rod 305, so that the positioning insert 307 can be inserted into the positioning hole 9, and the telescopic rod 4 can extend from the inner cavity of the telescopic shell 1 to a suitable length. The telescopic shell 1 is fixedly installed in a suitable area next to the operating table through the cooperation of the first clamping plate 5, the second clamping plate 6, the connecting bolt 7 and the nut 8, saving the operator the step of holding the spreader, saving the physical strength of medical staff, and making it convenient for the operator to use.

[0038] Example 2

[0039] like Figures 2-8 As shown, in one embodiment, the surface of the support plate 209 is provided with several friction grooves 211, which are arranged equidistantly in a vertical direction. A guide rod 212 is fixedly installed in the inner cavity of the groove 210. The moving block 207 is slidably connected to the surface of the guide rod 212. The left and right sides of the mounting frame 201 are provided with moving grooves 213. The moving frame 205 passes through the moving grooves 213 and extends to the outside of the mounting frame 201. A limiting plate 214 is fixedly installed in the inner cavity of the mounting frame 201. The screw block 204 is slidably connected to the surface of the limiting plate 214. The front and rear sides of the bottom of the inner cavity of the housing 301 are provided with guide rods. The guide groove 308 and the positioning block 307 pass through the guide groove 308 and are inserted into the positioning hole 9. The front and rear sides of the inner cavity of the housing 301 are provided with sliding grooves 309. The front and rear sides of the lifting plate 306 are slidably connected in the sliding grooves 309. The slider 310 is fixedly installed in the inner cavity of the housing 301. The displacement block 302 is slidably connected to the surface of the slider 310. The top of the housing 301 is provided with a movable groove 311. The pressing block 304 passes through the movable groove 311 and extends to the top of the housing 301. The top of the telescopic shell 1 is provided with a displacement groove 10. The housing 301 passes through the displacement groove 10 and extends to the top of the telescopic shell 1.

[0040] By setting friction groove 211, the friction between the support plate 209 and muscle tissue can be increased compared to a smooth plate, preventing the support plate 209 from sliding out of the surgical area. By setting guide rod 212, the movement of moving block 207 can be limited to prevent it from deviating in direction during movement. By setting movement groove 213, the movement of moving frame 205 can be limited to ensure the accuracy of its movement direction. By setting limit plate 214, the movement of screw block 204 can be limited to prevent screw block 204 from rotating synchronously with screw 203. By setting guide groove 308, the positioning... The movement of the insert block 307 is guided to ensure the accuracy of its movement direction. The movement of the lifting plate 306 is guided by the slide groove 309 to prevent it from deviating in direction. The movement of the displacement block 302 is limited by the slider 310 to ensure the accuracy of its movement direction. The movement of the pressing block 304 is limited by the movable groove 311 to prevent it from deviating in direction. The movement of the housing 301 as a whole is guided by the displacement groove 10 to prevent the telescopic rod 4 from deviating when it drives the telescopic rod 4 to extend or retract.

[0041] In operation, the present invention works as follows: First, through the cooperation of the first clamping plate 5 and the second clamping plate 6, and the nut 8 and connecting bolt 7, the telescopic shell 1 is installed in a suitable area next to the operating table. Then, by squeezing the squeezing block 304, the displacement block 302 moves inward synchronously. At this time, the spring 303 is deformed due to the force. The displacement block 302, through its cooperation with the movable rod 305, causes the lifting plate 306 to drive the positioning insert 307 to move upward. Then, the shell 301 is pulled to the left, causing the telescopic rod 4 to extend out of the inner cavity of the telescopic shell 1. When the support plate 209 moves to the area that needs to be opened during surgery, the squeezing block 304 is released. At this time, the spring 303 loses the force and deforms again, through its own... Tension causes the displacement block 302 to move outward. At this time, the displacement block 302 cooperates with the movable rod 305. The movable rod 305 pushes the lifting plate 306 and the positioning block 307 downward. The positioning block 307 is inserted into the corresponding positioning hole 9 at its bottom, thus fixing the position of the telescopic rod 4 and the opening component 2. Then, by rotating the knob 202, the screw 203 rotates synchronously. The screw 203 drives the screw block 204 and the moving frame 205 to move backward. At this time, the moving frame 205 cooperates with the connecting rod 206. The connecting rod 206 pushes the moving block 207, the mounting rod 208 and the support plate 209 to move outward synchronously, so that the support plate 209 can open up the muscle tissue in the surgical area.

[0042] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
