After clamping, slide the first trapezoidal block 109, slide the first trapezoidal block 109 into the tooth groove of the first rack plate 107, and limit the first trapezoidal block 109 through the limiting component. The first trapezoidal block 109 limits the first rack plate 107 to prevent the first rack plate 107 from sliding in the arc opening 108, which is convenient for the staff to continue to clamp the aneurysm clip without maintaining the clamping force all the time, avoiding the loosening of the aneurysm clip due to maintaining the clamping force for a long time or other accidents.

[0043] like Figure 4 As shown, the limiting component includes a rectangular block 201, which is fixedly connected to the top end of one of the arc-shaped rods 104, a rectangular groove 202 is opened in the middle of the rectangular block 201, a sliding block 203 is slidably connected to the inner wall of the rectangular groove 202, a first spring 204 is fixedly connected between the inner wall of the rectangular groove 202 and the sliding block 203, a pull block 205 is fixedly connected to the front end of the sliding block 203, the pull block 205 slides through the front end of the rectangular block 201, the bottom end of the sliding block 203 is fixedly connected to an insertion rod 206, the insertion rod 206 slides through the lower end of the rectangular block 201 and the upper end of the arc-shaped rod 104, and a socket 207 cooperating with the insertion rod 206 is opened on the round block 209.

[0045] like Figure 5 As shown, a limiting rod 208 is arranged between the two arc plates 105, and the two arc plates 105 are both slidably connected to the outer surface of the limiting rod 208. The front and rear of the limiting rod 208 are symmetrically fixedly connected with round blocks 209, and the outer surface of the limiting rod 208 is rotatably connected with an arc plate 210, and the arc plate 210 is located on the outside of the arc plate 105. The limiting rod 208 slides through the two arc plates 105 and the arc plate 210, and the round block 209 is provided with a locking component for locking the arc plate 210.

[0046] When the angle of the device needs to be adjusted, the arc plate 210 is rotated, and the arc plate 210 is rotated on the limit rod 208 to adjust the angle of the device. When it is adjusted to a suitable angle, the arc plate 210 is locked by the locking assembly, which makes it easier for staff to clamp aneurysms in different positions.

[0048] When the arc plate 210 needs to be locked, first turn the knob 212 to screw the knob 212 out of the threaded hole 213, then rotate the arc plate 210 to adjust the angle of the device. After the adjustment is completed, turn the knob 212, the knob 212 drives the threaded rod 211 to rotate, and screw the threaded rod 211 into the threaded hole 213 on the arc plate 210 to restrict the arc plate 210.

A second spring 221 is fixedly connected between the inner wall of the rectangular sleeve 217 and the hollow rod 101, and the second spring 221 is sleeved on the outside of the push rod 220. A fixing component for fixing the push rod 220 is provided on the hollow rod 101.

[0050] When the length of the chuck 103 needs to be adjusted, the handle 219 is pressed downward, and the handle 219 drives the moving block 218 to slide in the rectangular sleeve 217, and the rectangular sleeve 217 drives the push rod 220 to slide, and the second spring 221 is stretched. When the push rod 220 contacts the inclined surface of the second trapezoidal block 216, the push rod 220 can push the second trapezoidal block 216 to slide in the moving groove 215, and the second trapezoidal block 216 drives the connecting rod 214 to slide outward, and the connecting rod 214 drives the chuck 103 to extend. When it is adjusted to the appropriate length, the push rod 220 is fixed by the fixing assembly to facilitate adaptation to aneurysm clips of different sizes.

[0051] like Figure 8 As shown, the fixing assembly includes a fixing frame 222, and the fixing frame 222 is fixedly connected to one side of the rectangular sleeve 217.

[0052] When it is necessary to fix the length of the chuck 103, the push block 224 is pushed, and the push block 224 drives the limiting rod 223 and the first magnet 225 to slide in the fixing frame 222, and the limiting rod 223 and the first magnet 225 are slid through the circular hole 226 into the U-shaped shell 227. When the limiting rod 223 contacts the second magnet 228 in the U-shaped shell 227, the limiting rod 223 is restricted by the mutual attraction between the second magnet 228 and the first magnet 225 to prevent the push rod 220 from sliding freely.

The worm 235 cooperates with the worm wheel 234, and the top of the worm 235 is fixedly connected with a screw block 236.

[0056] When the length of the hollow rod 101 needs to be adjusted, the screw block 236 is turned, and the screw block 236 drives the worm 235 to rotate, the worm 235 drives the worm wheel 234 to rotate, the worm wheel 234 drives the connecting column 232 to rotate, the connecting column 232 drives the gear 233 to rotate, the gear 233 drives the second rack plate 230 and the connecting plate 229 to slide in the arc rod 104, and the connecting plate 229 drives the hollow rod 101 to move outward to adjust the length of the hollow rod 101.

[0063] Then, the handle 219 is pressed downward, and the handle 219 drives the moving block 218 to slide in the rectangular sleeve 217, and the rectangular sleeve 217 drives the push rod 220 to slide, and the second spring 221 is stretched. When the push rod 220 contacts the inclined surface of the second trapezoidal block 216, the push rod 220 can push the second trapezoidal block 216 to slide in the moving groove 215, and the second trapezoidal block 216 drives the connecting rod 214 to slide outward, and the connecting rod 214 drives the chuck 103 to extend. When it is adjusted to a suitable length, then, the push block 224 is pushed, and the push block 224 drives the limiting rod 223 and the first magnet 225 to slide in the fixing frame 222, and the limiting rod 223 and the first magnet 225 are slid through the circular hole 226 into the U-shaped shell 227. When the limiting rod 223 When it contacts the second magnet 228 in the U-shaped shell 227, the limiting rod 223 is restricted by the mutual attraction between the second magnet 228 and the first magnet 225 to prevent the push rod 220 from sliding freely. Then, the knob 212 is turned to screw the knob 212 out of the threaded hole 213, and the arc plate 210 is rotated. The arc plate 210 rotates on the limiting rod 208 to adjust the angle of the device. When it is adjusted to a suitable angle, the knob 212 is turned to drive the threaded rod 211 to rotate, and the threaded rod 211 is screwed into the threaded hole 213 on the arc plate 210 to restrict the arc plate 210. The arc rubber pad 237 can generate friction between the staff's hand and the arc plate 210.

[0064] Subsequently, the pull block 205 is pulled, and the pull block 205 drives the sliding block 203 to slide in the rectangular groove 202, the first spring 204 is compressed, and the sliding block 203 drives the insertion rod 206 to leave the insertion hole 207 on the first trapezoidal block 109, and then the first trapezoidal block 109 is slid to release the first trapezoidal block 109 from limiting the first rack plate 107. Subsequently, the staff controls the two arc plates 105 to move closer to the inside, and the arc plates 105 drive the arc rod 104 and the hollow rod 101 to move closer to each other, and the hollow rod 101 drives the clamp 103 to close the aneurysm. The clamp is clamped. After clamping is completed, the first trapezoidal block 109 is slid into the tooth groove of the first rack plate 107, and then the pull block 205 is released, the first spring 204 rebounds, the pull block 205 drives the sliding block 203 to slide, and the sliding block 203 drives the insertion rod 206 to be inserted into the insertion hole 207 to restrict the first trapezoidal block 109. The first trapezoidal block 109 limits the first rack plate 107 to prevent the first rack plate 107 from sliding in the arc opening 108, so as to facilitate the staff to continue to clamp the aneurysm clip.
