[0002] The vertebral lamina biting forceps are mainly used for biting off or trimming the vertebral lamina bone and skull. When using the currently used vertebral lamina biting forceps, hold the right forceps handle and move the left forceps handle closer to the right forceps handle, so that the upper forceps rod moves forward to bit off or trim the vertebral lamina bone or skull.
[0003] When the vertebral laminae bite forceps are actually used, since the upper clamp rod and the lower clamp rod can only move relative to each other and cannot be separated, blood or other contaminants will remain in the gap between the upper clamp rod and the lower clamp rod after use. Due to the obstruction of the upper clamp rod and the lower clamp rod, the contaminants in the gap are difficult to remove. Therefore, in the process of cleaning and disinfecting after using the vertebral laminae bite forceps, even if the entire vertebral laminae bite forceps are cleaned and disinfected, the contaminants remaining in the gap are still difficult to be completely removed, which can easily cause cross infection and bring hidden dangers to patients. Therefore, the present application provides a vertebral laminae bite forceps to meet the needs. Utility Model Content

[0032] like Figures 1 to 5 As shown, the utility model provides a vertebral plate biting forceps, including a lower clamp rod 1, and also including an upper clamp rod 2, which is slidably assembled on the lower clamp rod 1; a movable clamp rod 3, which is movably mounted on the upper clamp rod 2; a movable mechanism 4, which is movably mounted inside the upper clamp rod 2; a positioning component 5, which is movably assembled inside the movable mechanism 4; the movable mechanism 4 includes a cavity 401, the cavity 401 is opened inside the upper clamp rod 2, the right end of the movable clamp rod 3 is fixedly connected to a connecting block 402, the connecting block 402 is hinged with a movable block 403, the right end of the movable block 403 is fixedly connected to a limiting block 404, and the limiting block 404 is slidably assembled on the upper clamp rod 2, when the connecting block 402 moves to the inside of the cavity 401, the movable clamp rod 3 will not be able to rotate, so it can move with the upper clamp rod 2, so as to bite dead bone or trim bone stumps, and the movable block 403 and the limit block 404 can move as a whole, so that the left end of the movable block 403 moves to the outside of the cavity 401. At this time, the connecting block 402 will also be located outside the cavity 401, so the movable clamp rod 3 can rotate around the hinged portion of the connecting block 402 and the movable block 403, so as to separate the lower clamp rod 1 from the movable clamp rod 3, thereby facilitating the cleaning of impurities in the gap.
[0033] like Figure 4As shown, the positioning assembly 5 includes a fixing pin 501 and a block 502. The fixing pin 501 is slidably installed inside the limit block 404. The fixing pin 501 and the block 502 are fixedly connected. The block 502 is slidably assembled inside the limit block 404. Through the design of the fixing pin 501, the fixing pin 501 can be clamped on the upper clamp rod 2, thereby fixing the limit block 404, making the limit block 404 unable to move, so that the connecting block 402 and the movable block 403 cannot move to the outside of the cavity 401, thereby making the movable clamp rod 3 unable to rotate, which is convenient for biting dead bone or trimming bone stumps through the lower clamp rod 1 and the movable clamp rod 3.
[0034] like Figure 4 As shown, the positioning assembly 5 also includes a push spring 503, which is arranged inside the limit block 404, and the two ends of the push spring 503 are respectively fixed to the limit block 404 and the block 502, and the push spring 503 is in a compressed state, so the push spring 503 will push the block 502, and when the fixing pin 501 shrinks toward the inside of the limit block 404, the limit block 404 can move, and when the limit block 404 moves to the right end inside the cavity 401, the push spring 503 can push the block 502, so that the fixing pin 501 moves away from the end of the block 502 to the outside of the upper clamp rod 2, thereby re-fixing the limit block 404.
[0035] like Figure 2 As shown, a slot 601 is provided inside the lower clamp rod 1, and a moving block 602 is slidably installed inside the slot 601. The moving block 602 is fixedly connected to the upper clamp rod 2, and the moving block 602 can only move inside the slot 601. Therefore, the slot 601 and the moving block 602 can limit the upper clamp rod 2, so that the upper clamp rod 2 can only move along the length direction of the lower clamp rod 1. When the upper clamp rod 2 moves, the lower clamp rod 1 and the movable clamp rod 3 can bite dead bone or trim bone stumps by pushing the movable clamp rod 3.
[0036] like Figure 1 As shown, the lower clamp rod 1 is internally hingedly equipped with a handle 7, and a support spring 8 is fixedly installed between the lower clamp rod 1 and the handle 7. The support spring 8 has an elastic recovery effect. When the medical staff holds the lower clamp rod 1 and presses the handle 7, the handle 7 will rotate around the hinged portion between it and the lower clamp rod 1, thereby squeezing the support spring 8, so that the support spring 8 is in a compressed state. When the medical staff releases the handle 7, the support spring 8 will reset, thereby pushing the handle 7 to move and reset it, thereby making it convenient for the medical staff to use.
[0037] like Figure 2As shown, a hollow groove 901 is provided inside the handle 7, and a round rod 902 is movably installed inside the hollow groove 901. The round rod 902 is fixed to the inside of the upper clamp rod 2. When the handle 7 rotates around the hinged portion between it and the lower clamp rod 1, the hollow groove 901 will move, so the round rod 902 will move inside the hollow groove 901. At the same time, the upper clamp rod 2 can be moved through the round rod 902, so that the lower clamp rod 1 and the movable clamp rod 3 can bite dead bones or trim bone stumps.
[0038] like Figure 4 As shown, one end of the fixing pin 501 away from the block 502 extends to the outside of the upper clamp rod 2, and the end of the fixing pin 501 away from the block 502 is hemispherical. Through the design of the fixing pin 501, when the fixing pin 501 is pressed, it will shrink toward the inside of the limit block 404, and the hemispherical end of the fixing pin 501 will be located between the upper clamp rod 2 and the limit block 404. At this time, the movement of the movable clamp rod 3 will pull the limit block 404 to move through the connecting block 402 and the movable block 403, so that the fixing pin 501 continues to shrink toward the inside of the limit block 404, thereby achieving the effect of releasing the fixation.
[0039] like Figure 1 As shown, the left end of the lower clamp rod 1 is upwardly tilted and has a certain inclination, and the left end of the movable clamp rod 3 is inclined and can be matched with the left end of the lower clamp rod 1. Through the design of the lower clamp rod 1 and the movable clamp rod 3, a clamp mouth part can be formed, and the left end of the lower clamp rod 1 can be completely fitted with the left end of the movable clamp rod 3, so that misalignment, deviation, bone residue impaction and the like will not occur.
[0040] like Figure 2 and Figure 5 As shown, the movable distance of the movable block 602 is greater than the spacing between the lower clamp rod 1 and the movable clamp rod 3, the width of the slot 601 and the bottom of the movable block 602 are greater than the width of the top, and the movable block 602 can only move along the length direction of the slot 601, so it can limit the upper clamp rod 2, and at the same time make the left end of the lower clamp rod 1 completely fit with the left end of the movable clamp rod 3.
[0041] like Figure 1 As shown, the handle 7 is arc-shaped, and the value of the surface roughness parameter Ra of the handle 7 is less than 0.4 μm. When used by medical staff, the shape of the handle 7 is more convenient for the medical staff to hold with four fingers, thereby making it more convenient for the medical staff to use.
[0042] According to the working principle of the utility model, when the medical staff needs to use it, they can press the handle 7, and the handle 7 will rotate around the hinged part between it and the lower clamp rod 1. At this time, the empty slot 901 will move, so the round rod 902 will move inside the empty slot 901, thereby pushing the upper clamp rod 2 to move through the round rod 902, so that the lower clamp rod 1 and the movable clamp rod 3 can bite dead bone or trim bone stumps, and the support spring 8 will be squeezed. When the medical staff releases the handle 7, the support spring 8 will reset, thereby pushing the handle 7 to move and reset it, and at the same time, the upper clamp rod 2 and the movable clamp rod 3 can be pulled to reset through the round rod 902.
[0043] Then, when cleaning and disinfecting, the medical staff needs to press the fixing pin 501, and the fixing pin 501 will shrink toward the inside of the limit block 404, so that the hemispherical end of the fixing pin 501 will be located between the upper clamp rod 2 and the limit block 404. Then the medical staff can pull the movable clamp rod 3, and the fixing pin 501 will continue to shrink toward the inside of the limit block 404, and the connecting block 402 and the movable block 403 will move toward the outside of the cavity 401. After that, the medical staff can rotate the movable clamp rod 3 to rotate it around the hinged part of the connecting block 402 and the movable block 403, thereby separating the lower clamp rod 1 and the movable clamp rod 3, which is convenient for subsequent cleaning and disinfection.
[0044] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
