[0001] This utility model relates to the field of visual ring saw technology, specifically a visual ring saw. Background Technology

[0002] A visual ring saw disclosed in CN220193107U solves the problem that the depth of the visual ring saw cannot be precisely adjusted in the prior art. The visual ring saw includes a tubular saw column, a rotating handle, a cylindrical barrel, a spiral groove, a positioning groove, a sliding ring, a positioning actuator, and a positioning switch. The rotating handle is fixed to the upper end of the tubular saw column, and the positioning actuator is fixed to the upper part of the tubular saw column. A sliding ring is slidably connected to the outer side of the tubular saw column, and a cylindrical barrel is fixed to the outer side of the sliding ring.

[0003] It makes the length of the visual ring saw extending into the working sleeve adjustable. The operator can adjust the depth of the visual ring saw by rotating the barrel to achieve the required depth for the surgery.

[0004] However, after adjusting the visual ring saw to the appropriate length, the positioning mechanism alone is not stable enough and can easily cause the visual ring saw to shake. This solution is not good for the positioning stability of the visual ring saw. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a visual ring saw that solves the problem that after adjusting the visual ring saw to a suitable length, the positioning mechanism alone is not stable enough, which can easily lead to the visual ring saw shaking.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a visual ring saw, including a ring saw body, with saw teeth fixedly installed at one end of the ring saw body, a scale provided on the surface of the ring saw body, a limiting component slidably connected to the surface of the ring saw body, a positioning block snapped into one side of the surface of the ring saw body, a through groove opened in the middle of the surface of the positioning block, snapping blocks fixedly installed at the four corners inside the through groove, and an installation block snapped into the surface of the positioning block;

[0007] The limiting component includes a positioning ring that is slidably connected to the surface of the ring saw body. The surface of the positioning ring has a threaded groove, and a threaded rod is threadedly connected inside the threaded groove. Support plates are fixedly installed at the four corners of the surface of the positioning ring.

[0008] In one specific embodiment, a baffle plate is fixedly installed at each of the four corners of the mounting block surface, and an embedding groove is provided at the bottom of the baffle plate, with a sterile pad provided inside the embedding groove.

[0009] In one specific embodiment, the mounting block has an internal mounting groove, the size of which is adapted to the size of the positioning block.

[0010] In one specific embodiment, the diameter of the positioning ring is larger than the diameter of the ring saw body, and the positioning ring slides up and down on the surface of the ring saw body.

[0011] In one specific embodiment, the ring saw body is made of sterile material, the ring saw body is 170mm long, the outer diameter of the ring saw body is 8mm, and the inner diameter is 7mm.

[0012] In one specific embodiment, the spacing between the scales is in millimeters, and the scales allow for observation of the insertion depth.

[0013] Compared with the prior art, this utility model provides a visual ring saw with the following advantages:

[0014] In the technical solution disclosed in this utility model, by using the setting of the limiting component and the ring saw body, during use, the personnel can insert the ring saw body into the patient's body, and then the personnel slide the limiting component up and down through the ring saw body. When the limiting component slides, it will limit the ring saw body, thereby improving the accuracy of inserting the ring saw body.

[0015] With the limiting components set by this utility model, during use, the operator will move the positioning ring through the ring saw body. When the positioning ring moves up and down, it will limit the insertion depth of the ring saw body. After the ring saw body is inserted into the appropriate position, the operator will rotate the threaded rod through the positioning ring. When the threaded rod rotates, it will position the positioning ring. The support plates at the four corners of the bottom of the positioning ring will support the positioning ring, improving the efficiency of positioning the ring saw body. Attached Figure Description

[0024] The specific problem addressed in this embodiment is the instability caused by the positioning mechanism alone after adjusting the visual ring saw to the appropriate length, which can easily lead to shaking of the ring saw. This invention utilizes the limiting component 4 and the ring saw body 1. During use, the operator can insert the ring saw body 1 into the patient's body, and then slide the limiting component 4 up and down through the ring saw body 1. As the limiting component 4 slides, it limits the movement of the ring saw body 1, improving the accuracy of insertion.

[0025] The limiting component 4 includes a positioning ring 41 slidably connected to the surface of the ring saw body 1. The surface of the positioning ring 41 has a threaded groove, and a threaded rod 42 is threadedly connected inside the threaded groove. Support plates 43 are fixedly installed at the four corners of the surface of the positioning ring 41. The diameter of the positioning ring 41 is larger than the diameter of the ring saw body 1. The positioning ring 41 slides up and down on the surface of the ring saw body 1. In this specific embodiment, during use, the operator will move the positioning ring 41 through the ring saw body 1. When the positioning ring 41 moves up and down, it will limit the insertion depth of the ring saw body 1. After the ring saw body 1 is inserted into the appropriate position, the operator will rotate the threaded rod 42 through the positioning ring 41. When the threaded rod 42 rotates, it will position the positioning ring 41. The support plates 43 at the four corners of the bottom of the positioning ring 41 will support the positioning ring 41, improving the efficiency of positioning the ring saw body 1.

[0026] In this specific embodiment, a baffle plate is fixedly installed at each of the four corners of the surface of the mounting block 7. The bottom of the baffle plate is provided with an embedding groove, and a sterile pad is provided inside the embedding groove. The mounting block 7 is provided with an installation groove, the size of which is adapted to the size of the positioning block 5. The ring saw body 1 is made of sterile material, the length of the ring saw body 1 is 170mm, the outer diameter of the ring saw body 1 is 8mm, the inner diameter is 7mm, the spacing between the scales 3 is millimeters, and the scales 3 can be used to observe the insertion depth.

[0027] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
