Description

Technical Field

[0001] This utility model relates to the field of surgical knife processing technology, specifically a surgical knife blade drilling and positioning device. Background Technology

[0002] In the 2018 edition of the Medical Device Classification Catalog, a scalpel is defined as a specialized cutting tool consisting of a blade and a handle, primarily used for cutting human or animal tissues. The earliest known surgical tool, a stone sickle unearthed in 1973 at the Shang Dynasty site in Taixi Village, Gaocheng, Hebei Province, dates back approximately 3400 years. The main components of a surgical scalpel include the handle, the blade, and the tip. The handle provides a comfortable grip and operational stability; the blade connects the handle and the tip and possesses high strength and corrosion resistance; and the tip is used for cutting tissue and performing surgical procedures. These components work together to ensure that surgeons can perform precise and safe surgical procedures. Through continuous technological advancements and innovations, the components of surgical scalpels are constantly being updated and improved to meet the requirements of different surgical needs.

[0003] Existing scalpels typically attach the blade to the handle by drilling holes in the blade itself. However, as a precision tool, a scalpel requires precision machining. Therefore, the drilling of holes in the scalpel blade needs to be precisely positioned to prevent installation errors that could affect its use. Thus, a scalpel blade drilling and positioning device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a surgical scalpel blade drilling and positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scalpel blade drilling and positioning device, comprising a base and a slide rail 1. Slide rods are slidably connected to the left and right sides inside the base. The slide rail 1 is installed above the base, and a fixed clamp is installed on the upper left side of the slide rail 1. A movable clamp is slidably connected to the upper right side of the slide rail 1, and a fastening knob 1 is threadedly connected to the front end of the movable clamp. By sliding the movable clamp to the left via the slide rail 1, the other end of the scalpel blade enters the movable clamp and clamping plate. Rotating the wing nut causes the clamping plate to descend and clamp the scalpel blade, thereby fixing the other end of the scalpel blade. Rotating the fastening knob 1 fixes the position of the movable clamp on the slide rail 1.

[0006] Furthermore, a clamping assembly is installed inside the upper part of the movable clamping seat, and a clamping plate is installed on the upper periphery of the clamping assembly. The fixed clamping seat has the same structure as the upper part of the movable clamping seat.

[0007] Furthermore, the clamping assembly includes a spring, a screw, and a wing nut. The screw is installed inside the spring, and the wing nut is slidably connected to the upper part of the screw. When the wing nut is rotated upward, the spring pushes the clamping plate to slide on the screw and always abut against the lower part of the wing nut, thereby opening the clamping plate and the fixed clamping seat. One end of the scalpel blade is placed between the clamping plate and the fixed clamping seat, and the wing nut is rotated to lower the clamping plate and clamp the scalpel blade.

[0008] Furthermore, a second fastening knob is installed on the left end of the base, and the second fastening knob is threadedly connected to the base. Rotating the second fastening knob fixes the position of the base on the sliding rod.

[0009] Furthermore, a base plate is installed below the slide rod, and the base plate is welded to the slide rod. The sliding base changes the front and back position of the base on the slide rod, thereby adjusting the front and back position of the scalpel blade on the horizontal plane.

[0010] Furthermore, a slider is installed below the substrate, and the slider is welded to the substrate. Sliding the slider changes the left and right position of the substrate on the second slide rail, thereby adjusting the left and right position of the scalpel blade on the horizontal plane.

[0011] Furthermore, a fastening knob three is installed at the front end of the slider, and the fastening knob three is threadedly connected to the slider. Rotating the fastening knob three fixes the position of the slider on the slide rail two.

[0012] Furthermore, a second slide rail is slidably connected to the lower interior of the slider, and a base is installed below the second slide rail. The base is placed on the drilling platform, and the base is kept horizontal with the drilling platform surface to ensure that the drill bit is perpendicular to the processing surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After placing the base on the drill table, rotate the wing nut upwards. The spring drives the clamping plate to slide along the screw and always abut against the bottom of the wing nut, so that the clamping plate and the fixed clamping seat are opened; place one end of the scalpel blade between the clamping plate and the fixed clamping seat, rotate the wing nut to make the clamping plate descend and clamp the blade; slide the movable clamping seat to the left through the slide rail one, so that the other end of the blade enters between the movable clamping seat and the clamping plate, rotate the wing nut again to make the clamping plate descend and clamp the blade, thereby fixing the other end of the blade; rotate the fastening knob one to lock the position of the movable clamping seat on the slide rail one. The spring can prevent the wing nut from loosening during drilling and causing the blade to shift, ensuring a stable fixation; adjust the front and rear position of the sliding base on the slide rod and fix it through the fastening knob two, then slide the slider to adjust the left and right position of the base plate on the slide rail two and fix it through the fastening knob three, thereby adjusting the position of the scalpel blade on the water surface, accurately positioning the drilling position below the drill bit, completing the precise positioning of the scalpel blade, which is convenient for subsequent fine processing;

[0014] 1. This utility model places the base on the drilling platform, rotates the wing nut upwards, and the spring pushes the clamping plate to slide on the screw, always abutting against the bottom of the wing nut, thereby opening the gap between the clamping plate and the fixed clamping seat. One end of the scalpel blade is placed between the clamping plate and the fixed clamping seat. Rotating the wing nut causes the clamping plate to descend and clamp the scalpel blade. The movable clamping seat is slid to the left through the slide rail, so that the other end of the scalpel blade enters the movable clamping seat and the clamping plate. Rotating the wing nut causes the clamping plate to descend and clamp the scalpel blade, thereby fixing the other end of the scalpel blade. Rotating the fastening knob fixes the position of the movable clamping seat on the slide rail. The spring prevents the wing nut from loosening during drilling, which would cause the scalpel blade to loosen, ensuring a stable fixation.

[0015] 2. The sliding base of this utility model changes the front-to-back position of the base on the slide rod and fixes the position by fastening knob two. The sliding slider changes the left-to-right position of the base plate on the slide rail two and fixes it by fastening knob three, thereby adjusting the position of the scalpel blade on the water surface and adjusting the drilling position to be positioned below the drill bit, thereby completing the precise positioning of the scalpel blade and facilitating fine processing.

[0020] like Figure 1-3As shown, a surgical scalpel blade drilling positioning device includes a base 1 and a slide rail 2. Slide rods 8 are slidably connected to the left and right sides inside the base 1. The slide rail 2 is installed above the base 1, and a fixed clamping seat 3 is installed on the upper left side of the slide rail 2. A movable clamping seat 4 is slidably connected to the upper right side of the slide rail 2, and a fastening knob 5 is threaded to the front end of the movable clamping seat 4. A clamping assembly 6 is installed inside the movable clamping seat 4, and a clamping plate 7 is installed on the upper periphery of the clamping assembly 6. The clamping assembly 6 includes a spring 601, a screw 602, and a wing nut 603. The screw 602 is installed inside the spring 601, and the wing nut 603 is slidably connected to the upper part of the screw 602. When the base 14 is placed stably on the drilling platform, the wing nut 603 is rotated upwards, and the spring 601... Then, push the clamping plate 7 to slide along the screw 602, keeping it firmly against the bottom of the wing nut 603, thus creating an open state between the clamping plate 7 and the fixed clamping seat 3; then, accurately place one end of the scalpel blade between the clamping plate 7 and the fixed clamping seat 3, and rotate the wing nut 603 in the opposite direction to lower the clamping plate 7 and clamp the blade; next, slide the movable clamping seat 4 to the left through the slide rail 2 to ensure that the other end of the scalpel blade smoothly enters between the movable clamping seat 4 and the clamping plate 7, and rotate the wing nut 603 again to lower the clamping plate 7 and clamp the blade, thus firmly fixing the other end of the scalpel blade; then rotate the fastening knob 5 to lock the position of the movable clamping seat 4 on the slide rail 2, while the spring 601 can effectively prevent the wing nut 603 from loosening during drilling, which would cause the scalpel blade to loosen, ensuring a stable and reliable fixation.

[0021] like Figure 1-3 As shown, a second fastening knob 9 is installed on the left end of the base 1, and the second fastening knob 9 is threadedly connected to the base 1. A base plate 10 is installed below the slide rod 8, and the base plate 10 is welded to the slide rod 8. A slider 11 is installed below the base plate 10, and the slider 11 is welded to the base plate 10. A third fastening knob 12 is installed at the front end of the slider 11, and the third fastening knob 12 is threadedly connected to the slider 11. A second slide rail 13 is slidably connected to the lower part of the slider 11, and a base 14 is installed below the slide rail 13. The front and rear positions of the base plate 1 on the slide rod 8 are adjusted by sliding the base 1, and the position is locked by the second fastening knob 9. At the same time, the slider 11 is slid to change the left and right positions of the base plate 10 on the slide rail 13, and then it is firmly fixed by the third fastening knob 12. This allows for precise control of the position of the scalpel blade on the water surface, adjusting and positioning the drilling position directly below the drill bit, thereby completing the precise positioning of the scalpel blade and providing strong support for subsequent fine processing operations.

[0022] Working Principle: When using this scalpel blade drilling and positioning device, firstly, the base 14 is firmly placed on the drill table. Then, the wing nut 603 is rotated upwards. At this time, the spring 601 pushes the clamping plate 7 to slide smoothly on the screw 602, ensuring that the clamping plate 7 is always tightly pressed against the bottom of the wing nut 603, thereby forming a certain opening angle between the clamping plate 7 and the fixed clamping seat 3. Next, one end of the scalpel blade is accurately placed into the gap between the clamping plate 7 and the fixed clamping seat 3. Then, the wing nut 603 is rotated in the opposite direction, causing the clamping plate 7 to descend and firmly clamp the scalpel blade. Afterwards, the movable clamping seat 4 is slid to the left through the slide rail 2, allowing the other end of the scalpel blade to smoothly enter the area between the movable clamping seat 4 and the clamping plate 7. The wing nut 603 is rotated again to lower the clamping plate 7 and clamp the scalpel blade, thereby achieving a stable fixation of the other end of the scalpel blade. Subsequently, the fastening knob 5 is rotated to lock the position of the movable clamp 4 on the slide rail 2. The spring 601 effectively prevents the scalpel blade from loosening due to the loosening of the wing nut 603 during drilling, ensuring a stable and reliable fixing process. Next, the base 1 is slidable to adjust its front-to-back position on the slide rod 8, and the position is fixed by the fastening knob 9. At the same time, the slider 11 is slidable to change the left-to-right position of the base plate 10 on the slide rail 13, and the position is fixed by the fastening knob 12. In this way, the position of the scalpel blade on the water surface can be precisely adjusted, and the drilling position is accurately positioned below the drill bit, thus completing the precise positioning of the scalpel blade and providing a strong guarantee for subsequent fine processing operations.
