Description

Technical Field

[0001] The utility model embodiment relates to the technical field of medical devices, and in particular to a thermal setting tool for a marker. Background Art

[0002] Currently, for small lung nodules larger than 1 cm in size, doctors can determine the location of the small lung nodules through naked eye observation and finger palpation. However, when the size of the small lung nodules is less than 1 cm, the failure rate of positioning methods through naked eye observation and finger palpation is greatly increased, and there is a risk of excessive surgical resection and increased patient trauma.

[0003] Therefore, when the lung nodule is small, the marker is delivered to the diseased site of the lung nodule through the airway via a transporter, and the marker expands and is fixed at the diseased site, making it easier for subsequent surgery.

[0004] However, the current markers are prone to uneven expansion during pre-forming, and sharp angles in the middle can easily damage the human body wall. In addition, the deformation size of the markers cannot be controlled, resulting in insufficient rebound force after release, thus affecting the accuracy of finger palpation. Utility Model Content

[0038] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0042] As described in the background technology of this application, currently when the lung nodules are small, the markers are delivered to the diseased site of the lung nodules through the airway via a conveyor, and the markers are expanded and fixed at the diseased site to facilitate subsequent surgery.

[0043] The inventors of the present application have discovered that, with current markers, the transverse diameter and radial length cannot be precisely controlled and determined during processing and shaping, resulting in significant differences in the markers after molding; and sharp angles are easily created during pre-molding due to uneven expansion, thereby causing damage to the walls of human tubes; and the expansion force at both ends of the marker is insufficient, resulting in reduced elasticity and insufficient resilience.

[0044] In order to solve the above problems, the inventor of the present application proposed the technical solution of the present application, and the specific embodiments are as follows:

[0045] Figure 1 It is a schematic diagram of the marker in the utility model after being formed, Figure 2 Schematic diagram of a heat setting tool for a marker in an embodiment of the present utility model, Figure 3 Schematic diagram of the connection between the chuck and the marker in the embodiment of the utility model. Figure 4 This is a schematic diagram of the assembly of the core rod and the marker in the embodiment of the utility model. Figure 5 is a schematic diagram of a chuck in an embodiment of the utility model, Figure 6 In the embodiment of the utility model Figure 5 Magnified view of point A in .

[0046] like Figure 1 As shown, the lung surgery marker in the utility model is made of nickel-titanium alloy, which has shape memory properties. The marker 10 is made by processing the nickel-titanium alloy tube. First, the nickel-titanium alloy tube is cut as required, and then the alloy tube is squeezed from the upper and lower ends to deform and expand the middle part of the alloy tube to preform a lantern-shaped marker ( Figure 1 When in use, the marker is shrunk into a tubular shape and placed in the outer sheath of the conveyor. When the marker is delivered to the pulmonary nodule lesion through the airway through the conveyor, the inner tube of the conveyor pushes the marker out, and the marker expands into a predetermined lantern shape and is positioned at the pulmonary nodule.

[0047] like Figures 2 to 6 As shown, the heat setting tooling of the marker of this embodiment includes: a mounting seat 1, a pushing assembly and a chuck 5. The pushing assembly is arranged on the mounting seat 1; the pushing assembly is used to clamp the two ends of the marker 10, and can squeeze and pull the marker 10 to deform the marker 10; the chuck 5 is arranged in the pushing assembly, and is used to restrict the lateral deformation of the marker 10; the chuck 5 is provided with a hook 51, and the hook 51 is used to hang with the marker 10.

[0048] It is understandable that in the heat setting tooling of the marker provided by the present application, during the heat setting process of the marker 10, the push assembly squeezes or pulls the marker, causing the marker 10 to deform and expand, and the hook 51 of the chuck 5 is used to hang with the marker. When the heat setting tooling of the marker of the utility model is used, the marker 10 is placed in the push assembly, and the chuck 5 is located in the push assembly and is hung with the marker 10 through the hook 51, so as to achieve the positioning function of the marker 10 and the function of limiting the deformation size of the marker 10. Through the chuck structure, the transverse size of the deformation of the marker 10 is precisely controllable, and the longitudinal size is constrained by the determined transverse size, so that the shaping size of the marker is precisely controllable, and the chuck 10 assists in positioning the marker during the marker forming process, so that the marker 10 is uniformly formed, and the product quality of the marker 10 is significantly improved.

[0049] In one embodiment, the pushing assembly includes: a first pressing plate 2, a second pressing plate 3 and a pushing rod 4; the first pressing plate 2 and the second pressing plate 3 are relatively arranged on the mounting seat 1, and respectively clamp the two ends of the marker; wherein the first pressing plate 2 and / or the second pressing plate 3 are slidably arranged relative to the mounting seat 4; the pushing rod 4 is slidably arranged on the mounting seat 1, and is used to drive the first pressing plate 2 and the second pressing plate 3 to move relative to each other, so as to squeeze and pull the marker 10 in the longitudinal direction.

[0050] In this embodiment, the first pressing plate 2 is fixedly arranged on the mounting seat 1. The second pressing plate 3 is slidably arranged on the mounting seat 1, and the second pressing plate 3 is located above the first pressing plate 2, and the second pressing plate 3 cooperates with the first pressing plate 2 to clamp the marker 10, and the push rod 4 is located above the second pressing plate 3, and the bottom of the push rod 4 is against the second pressing plate 3.

[0051] Exemplarily, the chuck 5 is in a circular ring shape, and a plurality of hooks 51 are provided on the inner wall of the chuck 5 .

[0052] In this embodiment, when the heat setting tool is used, the marker 10 is placed between the first pressing plate 2 and the second pressing plate 3, and the marker 10 is inserted into the chuck 5. The first pressing plate 2 and the second pressing plate 3 clamp the marker 10, and the second pressing plate 4 is pushed downward by the push rod 4. The second pressing plate 4 presses the marker 10 downward, so that the marker is deformed by force, and the middle part of the marker expands outward. When the marker 10 is slightly larger than the size of the hook 51 of the chuck 5, the chuck 5 is rotated to make the hook 51 clamped into the middle waist position of the marker 51, and then the marker 10 clamped into the chuck 5 is placed in a high-temperature furnace for quenching at 500°C for 1 minute, and then placed in ice water for tempering for 10s to 30s after quenching, that is, the heat setting of the marker 10 is completed. And multiple chucks 5 of different diameters are used, which are clamped in the waist of the marker 10 in turn for multiple high-temperature setting, to prevent the nickel-titanium wire of the marker from being directly broken due to excessive stress deformation.

[0053] It is not difficult to find from the above content that when the heat setting tooling of the marker of this embodiment is used, the marker is placed between the first pressing plate and the second pressing plate and is inserted into the chuck. The second pressing plate is pushed downward by the push rod, and the second pressing plate presses the marker downward, so that the marker is deformed by force, and the middle part of the marker expands outward. When the marker is slightly larger than the hook size of the inner diameter of the chuck, the chuck is rotated to make the hook of the chuck clamp into the middle waist position of the marker, and then the marker is heat-set. The transverse dimension of the marker deformation after molding is precisely controllable. By determining the transverse dimension to constrain the longitudinal dimension, the fixed dimension of the marker is precisely controllable, and the molding is uniform, and the quality of the marker product is significantly improved.

[0054] In one embodiment, the chuck is hollow in the middle, and the hook is arranged on the inner side wall of the chuck. When in use, the chuck is sleeved outside the marker, and the size of the transverse deformation of the marker is controlled by the inner diameter of the chuck. Specifically, the two ends of the marker are squeezed by the pushing assembly, so that the radial size of the marker is larger than the size of the hook of the inner diameter of the chuck, and the chuck is rotated so that the hook of the chuck is inserted into the middle waist position of the marker, and then the marker is heat-formed, and the transverse size of the marker after molding can be precisely controlled. Through the cooperation of the pushing assembly, the marker will no longer be squeezed after the transverse size is determined, so the longitudinal size can be constrained after the transverse size is determined, so that the precise control of the molding size of the marker is achieved.

[0055] Of course, in other embodiments, the hook may also be disposed on the outer side wall of the chuck, so that the lateral dimension of the chuck is guided and constrained by the outer side wall of the chuck.

[0056] Optional, such as Figure 2 As shown, the heat setting tooling for the marker in this embodiment further includes: an upper cover 6.

[0057] The mounting seat 1 is provided with a U-shaped groove, and the first pressing plate 2 is arranged at the bottom of the U-shaped groove of the mounting seat 1; the upper cover 6 is covered on the notch of the U-shaped groove and connected to the mounting seat, and one end of the push rod passes through the upper cover 6 and abuts against the second pressing plate 3.

[0058] The upper cover 6 is arranged on the mounting base 1, and is located at the top of the U-shaped groove of the mounting base 1, and the upper cover 6 closes the opening of the U-shaped groove. The mounting base 1 is provided with two guide structures 11 in the U-shaped groove, and the upper and lower ends of the guide structure 11 are respectively arranged on the upper cover 6 and the first pressing plate 2.

[0059] The second pressing plate 3 is slidably disposed on the guide structure 11 through the guide hole. In other embodiments, the first pressing plate 2 may also be slidably disposed on the guide structure 11 through the guide hole.

[0060] A threaded hole is provided at the center of the upper cover 6 .

[0061] The push rod 4 is provided with an external thread, and the push rod 4 is engaged with the threaded hole of the upper cover 3 through the external thread. The lower end of the push rod is abutted against the second pressing plate 3. When the push rod 4 rotates, it pushes the second pressing plate 3 to move downward.

[0062] Furthermore, in the heat setting tooling of the marker in this embodiment, both ends of the upper cover 6 are fixed to the side walls of the U-shaped groove of the mounting base 1 by connecting bolts, and the first pressing plate 2 is fixed to the bottom wall of the U-shaped groove of the mounting base 1 by connecting bolts.

[0063] Furthermore, in the heat setting tooling of the marker in this embodiment, a limiting groove 31 is provided on the top surface of the second pressing plate 3, and the limiting groove 31 of the second pressing plate 3 is adapted to the push rod 4, and the bottom end of the push rod 4 is embedded in the limiting groove 31 of the second pressing plate 3, so as to facilitate the pushing of the second pressing plate 3.

[0064] Further, such as Figure 3 , Figure 5 As shown, in the heat setting tooling of the marker in this embodiment, the chuck 5 is provided with seven hooks 51, which are evenly arranged on the inner wall of the circular ring of the chuck 5, and the hooks 51 extend toward the center of the chuck 5 to hang the marker 10. It should be noted that in other possible embodiments, the design of the hooks can also be other numbers, not limited to seven, and the design of seven hooks is only a preferred solution. For example, the number of hooks can also be four, six, etc., which will not be repeated in this embodiment.

[0065] Furthermore, in the heat setting tooling of the marker in this embodiment, the inner side surfaces of the multiple hooks 51 of the chuck 5 are arc-shaped, and the inner side surfaces of the multiple hooks 51 are on the same circular ring, so that the hooks of the chuck are conveniently connected with the marker when the chuck rotates.

[0066] In one embodiment, the hook 5 has a shaping portion 511, which has a certain width. The straight design in the middle of the shaping portion 511 ensures that the waist position of the marker 10 is also straight, avoiding the generation of uneven sharp parts; and the edge 512 on the shaping portion 511 that contacts the marker is arranged in an arc surface, so that the straight part of the waist of the marker is smoothly curved along both ends during molding, avoiding sharp angles caused by uneven molding of the marker 10, thereby causing damage to the tube wall.

[0067] Further, such as Figure 5 , Figure 6 As shown, in the heat setting tooling of the marker in this embodiment, the chuck 5 is provided with a baffle 52 on the outer side of the hook 51, and the baffle 52 blocks the marker 10 to prevent the marker from sliding off the hook.

[0068] Further, such as Figure 3 , Figure 4 As shown, the heat setting tooling for the marker in this embodiment further includes: a core rod 7, and both ends of the core rod 7 are chamfered to form an arc shape.

[0069] When in use, the core rod 7 is inserted into the marker 10, and the two ends of the core rod 7 abut against the two ends of the marker 10 to expand the marker 10, so as to evenly expand the two end sizes of the marker 10 and prevent the marker from being unevenly formed and producing sharp corners.

[0070] Further, such as Figure 2 As shown, the heat setting tooling for the marker in this embodiment further includes: a positioning rod 8. The positioning rod 8 in this embodiment is a stainless steel round rod 8.

[0071] The stainless steel round rod 8 is sequentially passed through along the axial direction of the push rod 4. Specifically, corresponding positions of the push rod 4, the second pressure plate 3, the core rod 7, the first pressure plate 2 and the mounting seat 1 are provided with through holes. The stainless steel round rod 8 sequentially passes through the push rod 4, the second pressure plate 3, the core rod 7, the first pressure plate 2 and the mounting seat 1 from top to bottom, and passes through the through hole of the marker 10, so that the marker remains vertical and does not deviate.

[0072] The heat setting tooling of the marker of the utility model and the processing technology of the marker are as follows:

[0073] The marker is heat-set in multiple steps to prevent the marker from cracking and deforming due to excessive stress deformation, and to better reduce its hardness and obtain good support strength. Each step of heat setting has a heat setting tooling corresponding to its size, that is, replacing the heat setting tooling with a chuck of the corresponding size. The chuck can better control the deformation of the marker and obtain the ideal product size during the heat setting process.

[0074] Before the final step of heat setting, the core rod is inserted into the marker, so that the length and diameter of the marker can be more accurately controlled. At the same time, the entire heat setting process of the marker does not exceed 10 minutes.

[0075] The heat setting processing method of the marker is:

[0076] The first step is to place the processed marker and waist chuck between the second pressure plate 3 and the first pressure plate 2, insert a positioning rod 8 in the middle, insert it from the through hole of the push rod 4, and pass through the second pressure plate 2, the marker, the chuck, the first pressure plate 2 and the mounting seat 1 in the middle.

[0077] The second step is to twist the push rod 4 downward to squeeze the marker to a size slightly larger than the chuck, and rotate the chuck 5 to clamp the marker in the middle waist position. Then put the marker clamped in the chuck 5 into a high-temperature furnace for quenching at 500℃ for 1 minute, and after quenching, put it into ice water for tempering for 10 to 30 seconds.

[0078] The third step is to continue to squeeze the marker downwards, replace the chuck 5 with a slightly larger diameter than that in the second step and clamp it into the waist of the marker, then put the marker clamped in the chuck into a high-temperature furnace for quenching at 500°C for 3 minutes, and after quenching, put it into ice water for tempering for 10 to 30 seconds.

[0079] In the fourth step, insert the upper and lower mandrels 7 into the two ends of the tempered marker 10. Then put the marker 10 and the chuck 5 inserted with the mandrel 7 between the second pressing plate 3 and the first pressing plate 2, and then use a positioning rod 8 to penetrate through the through hole of the push rod 4, pass through the second pressing plate 3, the marker, the chuck 5 and the first pressing plate 2, and then pass through the through hole of the mounting seat 1, so that the marker remains vertical and does not deviate.

[0080] The fifth step is to twist the push rod 4 downward to squeeze the marker to a size slightly larger than the chuck, rotate the chuck 5 to clamp the marker 10 in the middle waist position, and then put the marker inserted into the core rod 7 and the chuck 5 into a high-temperature furnace for quenching at 500°C for 5 minutes. After completion, put it into ice water for tempering for 10 to 30 seconds.

[0081] Step 6: Put the marker 10 into the heat setting tooling, turn the push rod 4 downward to squeeze the marker to a size slightly larger than the chuck 5, remove the chuck 5, and then take out the core rod 7.
