Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to a retractor for assisting robot oral implantation. Background Art

[0002] In oral implant surgery, most cases involve flap incisions. At this time, soft tissue traction of the mucoperiosteum is a very necessary operation. It can pull away the gingival tissue covering the bone surface of the implant area, provide an adequate surgical field of view, and intuitively expose the bone in the implant area so that the surgeon can accurately assess the bone condition and implantation site to avoid inadvertent involvement during the preparation of the implant cavity and the placement of the implant, which may cause gingival tearing and affect the subsequent bone integration of the implant and the healing of the gingival incision.

[0003] The above process often requires the surgeon and other assistants to operate together. At this time, the long handle of the pulling instrument and the hands of the surgeon and assistant often block the direction of the implant drill. Especially in robotic surgery, it sometimes blocks the information points on the calibration plate captured by the robot camera, affecting the efficiency of the operation and the accuracy of the implant site. In addition, pulling the soft tissue for a long time may also bring discomfort to the patient, and even tear the gum tissue if the operation is not done properly.

[0004] Therefore, in order to solve the above problems, a retractor for assisting robotic oral implantation is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a retractor for assisting robot oral implantation, so as to solve the technical problems in the prior art that manual retraction or long-handled retraction instruments are prone to low efficiency of robot implantation surgery and the risk of implantation failure.

[0027] The utility model provides a retractor for assisting robot oral implantation, which improves operation efficiency and patient safety.

[0028] Combine the following Figure 1 to Figure 3 The technical solution provided by the utility model is described in more detail.

[0029] The utility model provides a retractor for assisting robot oral implantation, comprising a retractor body 1, wherein the retractor body 1 has at least two retracting parts 11, and the at least two retracting parts 11 can respectively open the soft tissue flaps on both sides of the implantation site in a direction away from the implantation site.

[0030] The utility model provides a retractor for assisting robot oral implantation, comprising a retractor body 1, wherein the retractor body 1 has at least two retracting parts 11, and the at least two retracting parts 11 can respectively stretch the soft tissue flaps on both sides of the implantation site in a direction away from the implantation site, so that the implantation area can be completely exposed, freeing the operator's hands to pull the mucoperiosteal flap, facilitating operation, especially when used in oral robot implantation surgery, it can avoid the phenomenon that the operator obstructs the calibration plate due to pulling the mucoperiosteum during the operation, resulting in inaccurate implantation, and prevent the reamer drill from rolling the mucosal soft tissue into the cavity, thereby reducing the risk of implantation failure. This method is safer and more reliable, and can improve the efficiency of robot implantation. When used specifically, after the flap is incised and turned over during oral implantation surgery, one retractor is placed at the mesial and distal ends of the implantation site, and at least two retracting parts 11 are inserted between the periosteum and the bone surface, so as to fully expose the surgical area, reduce the introduction of soft tissue during the cavity preparation / implantation process under non-direct vision, and reduce the risk of implantation failure.

[0031] In one embodiment of the present invention, the retractor body 1 includes a main body 12 and two pulling parts 11 connected at both ends of the main body 12. The main body 12 and the pulling parts 11 are flat plate structures, and the two pulling parts 11 are arranged at an angle of 45 degrees with the main body 12.

[0032] In this embodiment, the retractor body 1 includes a main body 12 and two retraction parts 11, and the two retraction parts 11 are arranged at both ends of the main body 12, and the two retraction parts 11 are arranged at a 45-degree angle with the main body 12, so that when the retraction part 11 is inserted between the periosteum and the bone surface, the main body 12 and the retraction part 11 can stretch the soft tissue flaps on both sides of the implantation site away from the implantation site, so that the implantation area can be completely exposed, freeing the operator's hands to retract the mucoperiosteal flap, facilitating operation, especially when used for oral robot implant surgery, it can better avoid the phenomenon that the operator during the operation blocks the calibration plate due to retraction of the mucoperiosteum, resulting in inaccurate implantation. This method is safer and more reliable.

[0033] It should be noted that the main body 12 has different lengths and widths to adapt to different widths of missing teeth and alveolar ridge shapes to ensure the best soft tissue pulling effect. The connection between the main body 12 and the two pulling parts 11 adopts an arc transition.

[0034] During specific use, after cutting the gums and fully turning over the mucoperiosteal flap, select a soft tissue retractor of appropriate width and length according to the width and shape of the alveolar ridge at different implant sites and the tooth spacing in the edentulous area, and insert the two retracting parts 11 between the mucoperiosteal flap and the bone surface on the mesial or distal side of the flap area, so that the retracting parts 11 stretch the soft tissue flap. Place a soft tissue retractor on the mesial and distal sides of the implant site respectively, so as to fully stretch the soft tissue and expose the bone surface of the implant area.

[0035] Optionally, the main body 12 and / or the pulling portion 11 is a rectangular frame structure; or the main body 12 and / or the pulling portion 11 is an arc-shaped plate structure.

[0036] Furthermore, the retractor body 1 is made of an elastic material, and when the two retracting parts 11 are driven to move away from each other, the retractor body 1 can apply an elastic clamping force to at least the two retracting parts 11 to move them closer to each other.

[0037] In this further improved solution, the retractor body 1 is made of elastic material, which can increase the clamping force between the two retracting parts 11 and the area to be implanted, ensuring a better connection effect and making it safer and more reliable.

[0038] More specifically, the pulling portion 11 has the same width as the main body 12 , the width of the main body 12 is 2-5 mm, and the length of the main body 12 is 7-20 mm; the width of the pulling portion 11 is 2-5 mm, and the length of the pulling portion 11 is 5-10 mm.

[0039] In one embodiment of the present invention, a positioning portion 13 is disposed at the end of the pulling portion 11 , and a bite structure 14 is disposed on the positioning portion 13 , and the bite structure 14 is a sawtooth structure.

[0040] In other embodiments of the present invention, the engaging structure 14 is a wave-shaped structure.

[0041] In the above optional embodiment, a positioning portion 13 is provided at the end of the pulling portion 11, and an engaging structure 14 is provided on the positioning portion 13. The engaging structure 14 is a serrated structure or a wavy structure so as to be inserted between the soft tissue flap and the bone surface to provide stable retention and support.

[0042] It is understandable that the positioning portion 13 may also be directly configured as a wave-shaped structure, and the positioning portion 13 is positioned between the soft tissue flap and the bone surface to provide stable retention and support.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
