[0039] See also Figures 1 to 5The utility model discloses a soft tissue retractor with pressure feedback function for oral implant surgery, comprising a mounting shell 1, the mounting shell 1 is provided with a scale 11, the interior of the mounting shell 1 is connected with a tension spring 2, the other end of the tension spring 2 is connected with a sliding limit block 3, the side of the sliding limit block 3 away from the tension spring 2 is connected with a mounting column 4, the end of the mounting column 4 is connected with a pulling hook 15; the side of the mounting shell 1 away from the mounting column 4 is fixedly connected with a pull ring 13; for the convenience of warning and observation, the color of the sliding limit block 3 is preferably red.

[0040] See also Figure 3 The mounting column 4 is connected to the pull hook 15 through a connecting mechanism 14. The connecting mechanism 14 includes a connecting plate 1401 connected to the pull hook 15. A return spring 1402 is connected to the interior of the connecting plate 1401. A sliding cylinder 1403 is connected to the free end of the return spring 1402. The sliding cylinder 1403 can slide along the elastic direction of the return spring 1402. A clamp 1404 is fixedly connected to the side of the sliding cylinder 1403 away from the return spring 1402. Figure 4 A connecting groove 1405 is provided inside the mounting column 4, and a clamping hole 1046 is provided on the connecting groove 1045; when the mounting column 4 is connected to the pulling hook 15, the connecting plate 1401 is inserted into the connecting groove 1405, and the clamping hole 1406 is engaged with the clamping head 1404.

[0041] See also Figure 5 A sliding plate 5 is slidably connected to the inside of the mounting shell 1, and the sliding plate 5 longitudinally penetrates the two ends of the mounting shell 1 and slides freely along the longitudinal direction of the mounting shell 1. A fixed plate 6 is provided on the sliding plate 5, and a rotating plate 7 is hinged on the fixed plate 6. The top of the rotating plate 7 is provided with anti-slip grooves, and a clamping plate 8 is provided on the side of the rotating plate 7 close to the mounting column 4. A spring plate 9 is provided between the fixed plate 6 and the rotating plate 7, and the spring plate 9 is fixedly connected to the bottom of the rotating plate 7. A limiting hole is provided on the mounting shell 1 at a position corresponding to the rotating plate 7, and a plurality of latch teeth 10 are provided on both sides of the limiting hole, and the clamping plate 8 is engaged with the latch teeth 10; an observation hole 12 is provided on the sliding plate 5.

[0042] Working principle: When in use, first adjust the force threshold, press the side of the rotating plate 7 close to the spring plate 9, so that the rotating plate 7 can rotate. After the rotating plate 7 rotates, it can drive the card plate 8 to lift up and release the card tooth 10. At this time, push the rotating plate 7 in the direction of the pulling hook 15, so as to drive the fixed plate 6 to move in the direction of the pulling hook 15, and then drive the sliding plate 5 to move in the direction of the pulling hook 15. After the sliding plate 5 moves in the direction of the pulling hook 15, it can drive the observation hole 12 to move in the direction of the pulling hook 15. The required force can be seen through the scale 11 When the observation hole 12 reaches the force threshold, the rotating plate 7 is released, and the rotating plate 7 is reset under the action of the spring plate 9, thereby driving the clamping plate 8 to reset, so that the clamping plate 8 and the clamping tooth 10 are re-engaged, and the threshold setting is completed; when in use, the user pulls the pull ring 13, hangs the pulling hook 15 on the soft tissue, and pulls it with force. When pulling, the mounting column 4 will move outward, thereby driving the sliding limit block 3 to move in the direction of the mounting column 4. When the red sliding limit block 3 is seen through the observation hole 12, it means that the force threshold has been reached. At this time, the pulling force should be reduced to avoid straining the soft tissue.

[0043] When replacing the pulling hook 15, first push the clamp head 1404 toward the inside of the connecting plate 1401, so as to drive the sliding cylinder 1403 to move toward the inside of the connecting plate 1401, and then compress the reset spring 1402, and the pulling hook 15 can drive the connecting plate 1401 to move to the side away from the mounting column 4, and then the clamp head 1404 can be squeezed to move toward the inside of the connecting plate 1401 under the action of pressure, and then the connecting plate 1401 can be pulled out of the connecting groove 1405, so that the pulling hook 15 can be removed; when installing, press the clamp head 1404 toward the inside of the connecting plate 1401, and insert the clamp head 1404 into the inside of the connecting groove 1405, so it is convenient to install and disassemble.

[0044] In summary, the utility model provides a soft tissue retractor with a pressure feedback function for oral implant surgery, which can fix the position of the sliding plate through the cooperation of the retractor clamping plate and the clamping teeth, and then control the position of the observation hole, so that the force threshold can be set, and when pulling, the sliding limit plate can be moved to the position of the observation hole, so that the user can be reminded to reduce the force, thereby preventing excessive pulling of the soft tissue, and then protecting the patient's soft tissue from damage.
