Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture with a colored coating on the tail of a lung positioning needle. Background Technology
[0002] Lung positioning needles play a crucial role in marking and locating patients during percutaneous interventional procedures. Their ends are often connected to a suture, which is colored to distinguish product models, specifications, or corresponding surgical areas. Therefore, the accuracy, uniformity, and efficiency of the suture coloring process directly affect the safety and efficiency of clinical use. Currently, in production practice in this field, suture coloring mainly faces the following technical challenges: First, there is the issue of fixing and positioning the tail wire. The tail wire itself is a flexible and slender structure with a tiny positioning hook at one end. Traditional clamping methods (such as purely mechanical clamping plates or manual positioning) are difficult to achieve fast, accurate, and damage-free product fixing. Mechanical positioning requires high precision in parts machining and is prone to wear, leading to inaccurate positioning; manual operation suffers from poor consistency, low efficiency, and is prone to breaking the tail wire or damaging the positioning hook during operation.
[0003] Secondly, there is the challenge of achieving uniform coloring on both sides. To ensure that color markings are clearly visible from any angle, the tail line often requires full-circumferential coloring. Existing tooling typically only coats one side (usually the top) of the tail line. To achieve double-sided dyeing, operators must perform a secondary operation by flipping the tail line midway through the process. This not only significantly reduces production efficiency and increases operational complexity, but also makes it extremely easy for the already coated, undried pigment to be smudged or contaminated during the flipping process, resulting in product defects. Furthermore, it is difficult to ensure that the coloring position on the other side after flipping precisely corresponds to that on the first side. Utility Model Content
[0004] The purpose of this utility model is to disclose a lung positioning needle tail line color coating fixture, which can achieve rapid and accurate positioning and complete the coating of both sides uniformly in one go.
[0005] To achieve the above objectives, this utility model discloses a tooling fixture for color coating of a lung positioning needle tail thread, comprising: a fixture base, one end of which is provided with a sleeve assembly for mounting the tail thread, the sleeve assembly including a mounting rod arranged parallel to the top surface of the fixture base, the mounting rod being arranged along the width direction of the fixture base, the mounting rod being used to connect with the positioning hook of the tail thread; a cover, the cover being magnetically connected to the fixture base, the cover being provided with at least one hollow coating area; wherein, the top surface of the fixture base is provided with a dyeing area corresponding to each of the coating areas, the dyeing area being used to dye the bottom surface of the tail thread, and the coating area being used to dye the top surface of the tail thread.
[0006] By adopting the above solution, a mounting rod parallel to the width of the clamp base is specifically used to engage with the positioning hook at the end of the tail wire, achieving rapid and precise positioning of one end of the tail wire. Combined with the magnetic connection between the cover and the clamp base, the middle and other ends of the tail wire are smoothly pressed and fixed by magnetic force. The entire clamping process requires no complex mechanical alignment, avoids the instability of manual operation, is quick, and greatly reduces the risk of physical damage to the tail wire and positioning hook. A design combining a perforated coating area and a dyeing area on the base is employed. The perforated coating area on the cover allows operators to directly color the top surface of the tail wire. The key innovation lies in the dyeing area corresponding to the top of the clamp base, which can accumulate excess pigment seeping from the coating area. When the tail wire is pressed onto the dyeing area by the cover, its bottom surface comes into contact with the accumulated pigment, automatically completing the back-side dyeing. This achieves the effect of simultaneous double-sided coloring with a single clamping, completely eliminating the need for flipping, thoroughly avoiding the scratches caused by flipping, and ensuring precise alignment of the double-sided coloring areas, significantly improving production efficiency and product quality. The pigment stockpiled in the dyeing area forms a visual cue. Before starting to color the next tail thread, the operator can clearly see the color of the pigment stockpiled in the dyeing area, allowing for a direct comparison with the color needed. If there is a discrepancy, it can be immediately detected and corrected, effectively preventing batch color errors caused by using the wrong pigment, thus serving as a built-in error prevention and quality warning mechanism.
[0007] Furthermore, a partition beam is provided in the center of the coating area to separate it. The partition beam is arranged parallel to the mounting rod, and the bottom surface of the partition beam is aligned with the bottom surface of the cover to press the tail line so that it fits into the dyeing area.
[0008] By adopting the above scheme, the dividing beam acts as a physical barrier, effectively preventing the accidental flow or splashing of pigment of one color into an adjacent coating area during the coating operation. This strictly distinguishes different color areas, avoids cross-contamination and color mixing, and ensures the purity and accuracy of color identification. It also serves to press the tail line within the coating area, ensuring full and tight contact between the back of the tail line and the pigment accumulated in the dyeing area on the fixture base. This guarantees the uniformity, integrity, and consistency of dyeing on the back of the tail line, avoiding problems such as missed dyeing or light color due to localized lifting or poor adhesion of the tail line.
[0009] Furthermore, the dyeing area is provided with a liquid-absorbing plate for storing coating pigment. When coating is applied to the front of the tail line in the coating area, the liquid-absorbing plate absorbs the coating pigment, and at the same time, the liquid-absorbing plate dyes the bottom surface of the tail line.
[0010] By adopting the above scheme, the suction plate can effectively store and coat pigment, providing a stable and continuous source of pigment for dyeing the bottom surface of the tail line. It prevents pigment from flowing randomly within the dyeing area and from spreading to non-dyeing areas, maintaining a clean environment in the dyeing area, reducing pigment waste, and preventing the mixing and contamination between different colors of pigment, ensuring the purity and accuracy of the dyeing color on the bottom surface of each tail line. The relatively flat surface of the suction plate allows for full and uniform contact between the bottom surface of the tail line and the pigment. When the tail line is pressed against the suction plate, the suction plate ensures that all parts of the bottom surface of the tail line come into contact with the same amount of pigment, thereby achieving uniform dyeing and avoiding inconsistent dyeing depth caused by uneven pigment distribution, thus improving the quality of dyeing the bottom surface of the tail line.
[0011] Furthermore, the socket assembly also includes a support platform. The side of the support platform includes a first surface parallel to the length direction of the clamp base and a second surface parallel to the width direction of the clamp base. One end of the cover abuts against the second surface. The top surface of the support platform is aligned with the top surface of the cover. One end of the mounting rod is perpendicularly connected to the first surface, so that the tail line sleeved on the mounting rod is parallel to the length direction of the clamp base.
[0012] By adopting the above scheme, the tail wire sleeved on the mounting rod can be naturally and accurately parallel to the length direction of the fixture base, providing clear guidance for the installation of the tail wire on the tooling fixture, ensuring the consistency and accuracy of the tail wire installation position, and facilitating subsequent uniform and standardized coloring operations. The support platform provides a stable support structure for the mounting rod, enhancing its stability. The second side of the support platform abuts against the cover, providing quick and accurate positioning for the cover's installation on the fixture base, ensuring a tight fit between the cover and the support platform. Then, it is connected to the fixture base via magnetic attraction or other methods, simplifying the cover installation process and improving operational efficiency.
[0013] Furthermore, the clamp base is provided with a first notch corresponding to the other end of the mounting rod, and the orthographic projection of the mounting rod on the clamp base extends at least partially into the first notch.
[0014] By adopting the above solution, the presence of the first notch allows the end of the mounting rod to protrude from the edge of the clamp base, providing clearance space for the positioning hook of the tail line, so that the clearance hook can be easily fitted onto the mounting rod.
[0015] Furthermore, the edge of the clamp base is recessed inward to form at least one second notch, and the orthographic projection of the cover on the clamp base covers the second notch.
[0016] By adopting the above solution, the cover can be quickly grasped through the second notch, and the cover can be separated from the clamp base.
[0017] Furthermore, at least one alignment structure is provided between the fixture base and the cover. Accurate alignment ensures that the coating area on the cover perfectly corresponds to the dyeing area on the fixture base. During the coating process, the pigment can be evenly applied to the top and bottom surfaces of the tail line, avoiding the problem of over- or under-coating in some areas due to cover installation deviations.
[0018] By adopting the above scheme, the alignment structure provides clear guidance for the installation of the cover on the fixture base.
[0019] Furthermore, the alignment structure includes an alignment groove and an alignment block, one of which is located on the bottom surface of the cover and the other is located on the top surface of the fixture base.
[0020] By adopting the above solution, when the cover is placed on the fixture base, the alignment block can naturally embed into the alignment groove, achieving rapid and accurate positioning. Operators no longer need to make repeated adjustments and calibrations by visual inspection, greatly shortening installation time and improving production efficiency.
[0021] Furthermore, the top of the partition beam protrudes from the top surface of the cover to separate the coating area.
[0022] By adopting the above scheme, the raised portion of the separator beam increases the local thickness and strength of the cover, improving its compressive strength during the coating process. The raised structure also makes the boundaries between coating areas clearer.
[0023] Furthermore, the cover is provided with a first magnet assembly slot, and the clamp base is provided with a second magnet assembly slot. Magnetic suction components that attract each other are assembled in the first magnet assembly slot and the second magnet assembly slot.
[0024] By adopting the above solution, the mutual attraction between the magnetic components provides a natural guiding effect for the installation of the cover and the clamp base. When the cover approaches the clamp base, the magnetic components automatically attract it, guiding the cover to the correct position quickly and accurately, achieving precise alignment. Operators do not need to spend a lot of time and effort on detailed adjustments, greatly shortening the installation time and improving production efficiency.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting an installation rod that engages with the positioning hook at the end of the tail wire, one end of the tail wire can be quickly and accurately fixed to the installation rod, improving the speed and accuracy of positioning and reducing production errors and scrap rates caused by inaccurate positioning. The cover and the fixture base are magnetically connected, using magnetic force to smoothly press and fix the middle and other ends of the tail wire. This fixing method eliminates the need for complex mechanical alignment, avoids the instability of manual operation, is quick to operate, and greatly reduces the risk of physical damage to the tail wire and positioning hook, ensuring the stability of the tail wire during the coating process. 2. The cover has a perforated coating area, allowing operators to directly color the top surface of the tail wire, making operation convenient and intuitive. Simultaneously, the dyeing area on the top of the clamp base can collect excess pigment seeping from the coating area. When the tail wire is pressed against the dyeing area by the cover, its bottom surface comes into contact with the collected pigment, automatically completing the back-side dyeing. No additional complex operations are required, enabling simultaneous double-sided coloring with a single clamping of the tail wire. This completely eliminates the secondary operation step of flipping the tail wire required in traditional methods. Simply fix the tail wire to the mounting rod and close the cover to complete the top and bottom surface coloring in one go, greatly simplifying the operation process and reducing its complexity. 3. The simplified operation process and the design of clamping and coloring both sides at once significantly shorten the coloring time for each tail thread. In mass production, this can greatly increase production speed, increase output, and meet market demand; 4. The pigment stockpiled in the dyeing area itself forms a visual cue. Before starting to dye the next tail line, operators can clearly see the color of the pigment stockpiled in the dyeing area, allowing for a direct comparison with the color needed. If there is a discrepancy, it can be immediately detected and corrected, effectively preventing batch color errors caused by using the wrong pigment. This effectively reminds operators to strictly follow operating procedures during production, ensuring the consistency and stability of product quality. Attached Figure Description

[0034] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0035] Please refer to Embodiment 1 of this utility model. Figures 1 to 3 As shown, a tooling fixture for color coating of the tail line of a lung positioning needle is provided, comprising a fixture base 1 and a cover 3. The two are quickly closed and separated by magnetic adsorption. Through ingenious structural design, the rapid and accurate positioning of the tail line 5 of the lung positioning needle and the uniform coloring of both sides in one go are achieved. This effectively solves the pain points of the prior art, such as the difficulty in fixing the tail line 5, the complexity of coloring both sides and the easy occurrence of quality problems, and improves production efficiency and product quality.
[0036] Specifically, the clamp base 1 is a rectangular plate structure made of rigid plastic or metal, possessing good flatness and stability. One end of the clamp base 1 is provided with a socket assembly 2 for mounting the tail wire 5. In this embodiment 1, the socket assembly 2 includes a support platform 22 and a mounting rod 21. The side of the support platform 22 includes a section perpendicular to the length direction of the clamp base 1. Figure 1 , 2 The first surface 221 is parallel to the X direction and the surface is parallel to the width direction of the base. Figure 1 , 2 The second surface 222 is parallel to the Y-direction. The mounting rod 21 is preferably a metal round rod, one end of which is perpendicularly connected to and fixed to the first surface 221 of the support platform 22. The mounting rod 21 is parallel to and above the top surface of the clamp base 1, and is used to hook with the positioning hook 51 at the end of the tail line 5.
[0037] In some embodiments, in order to facilitate the assembly and attachment of the positioning hook 51 of the tail line 5, a first notch 13 is formed by recessing the other end edge of the fixture base 1 corresponding to the free end of the mounting rod 21. The orthographic projection of the mounting rod 21 at this end extends into the first notch 13, providing clearance space for the positioning hook 51 of the tail line 5 to be inserted.
[0038] On the top surface of the fixture base 1, a dyeing area 11 is provided corresponding to the dyeing station of the tail line 5. In this embodiment 1, two dyeing areas 11 are provided to meet the needs of two-color coating. Each dyeing area 11 can be fitted with a liquid absorption plate 111, which includes, but is not limited to, porous materials such as sponge and non-woven fabric, for absorbing and storing liquid pigment.
[0039] The cover 3 is also a rectangular plate structure, and its dimensions match those of the clamp base 1. The cover 3 is closed by magnetic attraction between its bottom surface and magnetic attraction within the clamp base 1. Specifically, a first magnet mounting slot 32 can be formed on the top surface of the cover 3, and a second magnet mounting slot 15 can be formed on the top surface of the clamp base 1. Each slot contains a permanent magnet that attracts the other, such as a neodymium iron boron magnet or a combination of a magnet and a magnetically conductive sheet. In other embodiments, the first magnet mounting slot 32 can also be located on the bottom surface of the cover 3, and similarly, the second magnet mounting slot 15 can also be located on the bottom surface of the clamp base 1, as long as the attraction between the two is achieved.
[0040] The cover 3 has coating areas 31 corresponding to the positions and number of dyeing areas 11 on the base. Each coating area 31 is a completely open window, allowing operators to directly apply color to the top surface of the tail line 5 below. A dividing beam 12 is located in the center of each coating area 31. This dividing beam 12 is parallel to the mounting rod 21 (i.e., along the Y direction), with its top protruding from the top surface of the cover 3, clearly dividing the coating area 31 into two parts and effectively preventing color mixing when different colors are applied. The bottom surface of the dividing beam 12 is aligned with the bottom surface of the cover 3, ensuring that the tail line 5 is pressed tightly when the cover 3 is closed, allowing its back side to fully adhere to the absorbent plate 111 of the dyeing area 11.
[0041] In some embodiments, to ensure the alignment accuracy of the cover 3 and the clamp base 1 when closed, an alignment structure 4 is provided between them. In this embodiment 1, the alignment structure 4 includes an alignment groove 41 on the bottom surface of the cover 3 and an alignment block 42 on the top surface of the clamp base 1. The alignment block 42 may be a cylindrical pin, and the alignment groove 41 is a matching circular hole. When closed, the alignment block 42 is inserted into the alignment groove 41 to ensure precise alignment between the coating area 31 on the cover 3 and the dyeing area 11 on the base. In other embodiments, the positions of the alignment block 42 and the alignment groove 41 can be interchanged.
[0042] Furthermore, in some embodiments, to facilitate the operator in opening the cover 3, at least one second notch 14 is recessed inward at the edge of the clamp base 1. When the cover 3 is closed, its orthographic projection precisely covers the second notch 14, allowing the operator to insert their fingers into this notch and easily apply force to overcome the magnetic force and open the cover 3.
[0043] The working steps and principle of this utility model are as follows: The operator inserts the positioning hook 51 at the end of the lung positioning needle tail line 5 onto the mounting rod 21 through the first notch 13. Due to the guiding and limiting effect of the mounting rod 21, the tail line 5 naturally lies flat and parallel to the length direction of the clamp base 1. The cover 3 is placed on the clamp base 1. The alignment block 42 and the alignment groove 41 guide the cover 3 to accurately fall into place, and the magnets attract each other to make them tightly closed. The partition beam 12 of the cover 3 presses the tail line 5 firmly onto the dyeing area 11 of the base. For coloring, the operator uses a coating tool such as a brush to color the top surface of the tail line 5 through the perforated coating area 31 on the cover 3. Excess pigment drips through the perforations onto the absorbent plate 111 of the dyeing area 11 below and is absorbed and accumulated. The pigment accumulated in the absorbent plate 111, under the continuous pressure of the cover 3, fully contacts the back of the tail line 5, thus simultaneously completing the dyeing of the back of the tail line 5. After coating is completed, simply lift the cover 3 by hand from the second notch 14 to remove the tail line 5 that has been evenly colored on both sides. At this time, the pigment color accumulated on the absorbent plate 111 in the dyeing area 11 can serve as a visual check mark before coloring the next tail line 5.
[0044] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
