Description

Technical Field

[0001] This utility model relates to the field of assembly and processing technology, and in particular to a tooling mechanism for assembling ultrasonic scalpel clamp components. Background Technology

[0002] like Figure 1 As shown, the clamping assembly in the ultrasonic scalpel head consists of a clamp 10 and a tissue pad 20. The clamp and tissue pad are assembled by the guide block 201 on the tissue pad 20 engaging with the guide groove 102 on the clamp 10, and then fixed by pressing the locking block 101 on the clamp 10 against the end face 202 of the guide block 201. However, the quality of the assembly between the clamp and the tissue pad directly affects the risk level of the ultrasonic scalpel head during clinical surgery. In the existing technology, the assembly between the clamp and the tissue pad is done manually by the operator using clamping tools such as tweezers. This not only easily causes damage to the clamp, affecting the assembly qualification rate and quality of the clamping assembly, but also makes the assembly process overly dependent on the operator's experience, making it difficult to ensure the consistency of assembly quality and assembly efficiency. Utility Model Content

[0003] Technical problems to be solved

[0004] This utility model provides a tooling mechanism for assembling ultrasonic scalpel clamp components. It can not only avoid the risk of low assembly pass rate and low assembly quality caused by damage to the clamp, but also solve the shortcomings of poor assembly quality consistency and low assembly efficiency.

[0005] Technical solution

[0006] An embodiment of this utility model provides a tooling mechanism for assembling an ultrasonic scalpel clamp assembly. The clamp assembly includes clamps and a tissue pad. The tooling mechanism includes a support platform; a fixing seat disposed on the support platform for mounting the ultrasonic scalpel clamp assembly to be assembled and restricting the movement of the ultrasonic scalpel clamp assembly along its width direction; and a pressing component disposed on the support platform and located above the fixing seat. The pressing component includes a cylinder fixedly disposed on the support platform and a pressure rod driven and connected to the cylinder. The pressure rod is located directly above a locking block on the clamp, and the pressure rod, driven by the cylinder, can press the tissue pad tightly onto the clamp.

[0007] Furthermore, the pressing assembly also includes a connecting rod connected to the drive end of the cylinder; and an adjusting bolt, one end of which is threaded to the connecting rod and the other end of which is threaded to the pressure rod, wherein the adjusting bolt is capable of adjusting the vertical distance between the pressure rod and the ultrasonic scalpel clamp assembly to be assembled.

[0008] Furthermore, the fixing base is provided with a first limiting groove for mounting the front end of the ultrasonic scalpel clamp assembly to be assembled and restricting the ultrasonic scalpel clamp assembly from moving along its width direction; a second limiting groove for mounting the middle end of the ultrasonic scalpel clamp assembly to be assembled and restricting the ultrasonic scalpel clamp assembly from moving along its width direction; and a first groove for accommodating the tail end of the ultrasonic scalpel clamp assembly to be assembled.

[0009] Furthermore, the first groove is provided with an L-shaped support block for supporting the tail end of the ultrasonic scalpel clamp assembly to be assembled.

[0010] Furthermore, the first groove is connected to the second limiting groove, and the bottom surface of the second limiting groove is flush with the top surface of the L-shaped support block.

[0011] Furthermore, the mounting base is also provided with a fine-tuning component for adjusting the movement of the ultrasonic scalpel clamp assembly to be assembled along its length direction.

[0012] Furthermore, the fine-tuning component includes an adjusting screw disposed on the fixed base and at one end away from the front end of the ultrasonic scalpel clamp assembly to be assembled.

[0013] Furthermore, the support platform includes a base plate on which the fixed seat is slidably disposed; a top plate on which the cylinder is fixedly installed; and a column disposed between the base plate and the top plate, with both ends connected to the base plate and the top plate respectively.

[0014] Furthermore, the base plate is provided with a slide rail, and the fixed seat is provided with a slide groove that is slidably connected to the slide rail.

[0015] Beneficial effects: In summary, by fixing the ultrasonic scalpel clamp assembly on the fixed base and positioning the pressure rod directly above the locking block on the clamp, and then using a cylinder to drive the pressure rod to press down on the locking block, the tissue pad and the clamp are forced to press and fasten together. This not only avoids the risk of damage to the clamp, resulting in low assembly qualification rate and low assembly quality, but also solves the shortcomings of poor assembly quality consistency and low assembly efficiency.

[0016] This invention adjusts the vertical distance between the pressure rod and the locking block on the clamp by changing the distance the adjusting bolt is screwed in and out of the threaded hole of the connecting rod. This not only avoids the tissue pad from not being able to be pressed and fastened to the clamp due to insufficient pressure depth of the pressure rod, thus affecting the assembly quality, but also avoids the clamp from being easily deformed and damaged due to excessive pressure depth of the pressure rod.

[0017] This invention adjusts the displacement of the ultrasonic scalpel clamp assembly along its length direction S by changing the movement distance of the adjusting screw in the first groove, which facilitates precise adjustment of the locking block on the clamp so that it is located directly below the pressure rod.

[0029] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to exemplarily illustrate the principle of this utility model, but should not be used to limit the scope of this utility model. That is, this utility model is not limited to the described embodiments, and covers any modifications, substitutions and improvements to the parts, components and connection methods without departing from the spirit of this utility model.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 3 As shown, this utility model relates to a tooling mechanism for assembling an ultrasonic scalpel clamp assembly. The clamp assembly includes a clamp 10 and a tissue pad 20. The tooling mechanism includes a support platform 1 and a fixing seat 2. The fixing seat 2 is disposed on the support platform 1 and is used to install the ultrasonic scalpel clamp assembly to be assembled and to restrict the movement of the ultrasonic scalpel clamp assembly along its width direction. Specifically, the ultrasonic scalpel clamp assembly to be assembled is characterized by a guide block 201 of the tissue pad 20 being disposed in a guide groove 102 on the clamp 10, and the locking block 101 on the clamp 10 not being pressed against the locking end face 202 of the guide block 201. The width direction refers to the horizontal direction perpendicular to the length direction S of the clamp 10 or the tissue pad 20; and the pressing component 3, which is disposed on the support platform 1 and located above the fixing seat 2, and the pressing component 3 includes a cylinder 31 fixedly disposed on the support platform 1 and a pressure rod 34 drivenly connected to the cylinder 31. Specifically, the fixed end of the cylinder 31 is fixedly disposed on the support platform 1, and the telescopic end of the cylinder 31 is drivenly connected to the pressure rod 34. The pressure rod 34 is located directly above the locking block 101 on the clamp 10, and the pressure rod 34 can press the tissue pad 20 tightly onto the clamp 10 under the drive of the cylinder 31.

[0032] This invention fixes the ultrasonic scalpel clamp assembly on the fixing base 2, with the pressure rod 34 positioned directly above the locking block 101 on the clamp 10. Then, the cylinder 31 drives the pressure rod 34 to press down on the locking block 101, forcing the tissue pad 20 and the clamp 10 to press and engage with each other. This not only avoids the risk of damage to the clamp, resulting in low assembly qualification rate and assembly quality of the clamp assembly, but also solves the problems of poor assembly quality consistency and low assembly efficiency.

[0033] As a preferred embodiment, such as Figures 1 to 3As shown, the pressing assembly 3 also includes a connecting rod 32 connected to the drive end of the cylinder 31; and an adjusting bolt 33, one end of which is threaded to the connecting rod 32, and the other end of which is threaded to the pressure rod 34. The adjusting bolt 33 can adjust the vertical distance between the pressure rod 34 and the ultrasonic scalpel clamp assembly to be assembled. Specifically, the connecting rod 32 has a first threaded hole (not shown in the figure) at the end away from the cylinder 31, and the pressure rod 34 has a second threaded hole (not shown in the figure) at the end near the adjusting bolt 33. Both ends of the adjusting bolt 33 have threaded sections, each threaded section being threaded into the corresponding first and second threaded holes. The distance the adjusting bolt 33 rotates in and out of the threaded hole of the connecting rod 32 can be adjusted to change the vertical distance between the pressure rod 34 and the clamp assembly. To ensure that the pressure rod 34 does not loosen during the pressing process, thread-locking adhesive is used to glue and fix the threaded connection between the adjusting bolt 33 and the pressure rod 34, as well as the threaded connection between the adjusting bolt 33 and the connecting rod 32. When it is necessary to readjust the screwing distance of the adjusting bolt 33 in the threaded hole of the connecting rod 32, it is only necessary to remove the thread-locking adhesive, adjust to the target distance, and then glue it again with thread-locking adhesive. Therefore, by changing the screwing distance of the adjusting bolt in the threaded hole of the connecting rod, the vertical height (i.e., the vertical distance) between the pressure rod and the locking block on the clamp can be adjusted. This not only avoids the tissue pad from not being able to be pressed and fastened with the clamp due to insufficient pressing depth, thus affecting the assembly quality, but also avoids the clamp from being easily deformed and damaged due to excessive pressing depth.

[0034] As another preferred implementation, such as Figure 4 and Figure 5As shown, the fixing base 2 is provided with a first limiting groove 21. The first limiting groove 21 is used to install the front end 200 of the ultrasonic scalpel clamp assembly to be assembled and to restrict the movement of the ultrasonic scalpel clamp assembly along its width direction. Specifically, the front end 200 of the ultrasonic scalpel clamp assembly to be assembled is engaged in the first limiting groove 21, and the first limiting groove 21 reserves space for the front end 200 of the ultrasonic scalpel clamp assembly to be assembled to move along its length direction S, that is, the end of the front end 200 of the ultrasonic scalpel clamp assembly (i.e., the end away from the tail end) and the first limiting groove 21. The inner wall of the first limiting groove 21 (i.e., the surface formed by inward concavity away from the tail end) does not contact the first limiting groove 21, and at least a portion of the contour edge of the first limiting groove 21 is adapted to the contour edge of the end of the front end 200 of the ultrasonic scalpel clamp assembly, so as to limit the displacement of the ultrasonic scalpel clamp assembly along its width direction; and a second limiting groove 22, which is used to install the middle end 300 of the ultrasonic scalpel clamp assembly to be assembled and to limit the movement of the ultrasonic scalpel clamp assembly along its width direction. Specifically, the middle end of the ultrasonic scalpel clamp assembly to be assembled... The side edge surface of the 300 is at least partially in contact with or abuts against the inner wall of the second limiting groove 22, so that the middle end 300 of the ultrasonic scalpel clamp assembly to be assembled can be placed or locked in the second limiting groove 22, so as to limit the displacement of the ultrasonic scalpel clamp assembly along its width direction; and the first groove 23 is used to receive the tail end 100 of the ultrasonic scalpel clamp assembly to be assembled. Specifically, since the overall external contour of the ultrasonic scalpel clamp assembly to be assembled is irregular in shape, and its bottom contour is... Since the curved surfaces are not on the same plane, in order to ensure that the ultrasonic scalpel clamp assembly to be assembled can be installed on the fixed base and to restrict the movement of the ultrasonic scalpel clamp assembly to be assembled along its width direction so that it does not move (such as tilting or shifting) during the pressing of the pressure rod 34, so as to achieve the mutual pressing and fastening of the tissue pad 20 and the clamp 10, the first limiting groove 21, the second limiting groove 22 and the first groove 23 are used to limit and support different positions on the ultrasonic scalpel clamp assembly to be assembled, thereby further ensuring the assembly quality.

[0035] As another alternative implementation method.

[0036] Preferably, such as Figure 4As shown, the first groove 23 is provided with an L-shaped support block 24 for supporting the tail end 100 of the ultrasonic scalpel clamp assembly to be assembled. The first groove 23 is connected to the second limiting groove 22, and the bottom surface of the second limiting groove 22 is flush with the top surface 241 of the L-shaped support block 24. Specifically, the stepped structure of the L-shaped support block 24 can be adapted to the outer contour of the tail end 100 of the ultrasonic scalpel clamp assembly to be assembled, so that the top surface of the clamp 10 can be kept basically parallel to the top surface of the fixing seat 2. This satisfies the requirement that the locking block 101 on the clamp 10 does not move (such as tilting or swaying) during the pressing of the pressure rod 34, so that the tissue pad 20 and the clamp 10 are pressed and fastened together.

[0037] Preferably, as shown in Figure 4 and Figure 5 As shown, the fixed base 2 is also provided with a fine-tuning component for adjusting the movement of the ultrasonic scalpel clamp assembly to be assembled along its length direction S. The fine-tuning component includes an adjusting screw 4 disposed on the fixed base 2 and away from the front end 200 of the ultrasonic scalpel clamp assembly to be assembled. Specifically, the fixed base 2 has a threaded hole at the end away from the first limiting groove 21. The adjusting screw 4 is threadedly connected to the fixed base 2 through the threaded hole and extends through the threaded hole into the first groove 23 of the fixed base 2. By screwing in and out the adjusting screw 4, the movement distance of the adjusting screw 4 in the first groove 23 can be changed. By pressing the tail end 100 of the ultrasonic scalpel clamp assembly to be assembled with the end of the adjusting screw 4, the displacement of the ultrasonic scalpel clamp assembly to be assembled along its length direction S is finely adjusted, so that the locking block 101 on the clamp 10 can be located directly below the pressure rod 34.

[0038] Preferably, such as Figure 2 As shown, the support platform 1 includes a base plate 11 with a fixed seat 2 slidably mounted on it; and a top plate 12 with a cylinder 31 fixedly mounted on it. Specifically, the fixed end of the cylinder 31 is fixed to the top plate 12. The top plate 12 is located between the base plate 11 and the top plate 12, and both ends are connected to the base plate 11 and the top plate 12 respectively. The adjusting bolt 33 and the pressure rod 34 are located between the top plate 12 and the base plate 11. The base plate 11 is provided with a slide rail 111. The fixed seat 2 is provided with a slide groove that is slidably connected to the slide rail 111. Specifically, the bottom of the fixed seat 2 is provided with a slide groove (not shown in the figure). By changing the sliding stroke of the fixed seat 2 on the base plate 11, the position of the fixed seat 2 on the base plate 11 can be adjusted, thereby adjusting the position of the ultrasonic scalpel clamp assembly on the support platform 1, and thus adjusting the position of the locking block 101 on the clamp 10 to be directly below the pressure rod 34.

Each embodiment focuses on describing the differences from other embodiments. This utility model is not limited to the specific steps and structures described above and shown in the figures. Furthermore, for the sake of brevity, detailed descriptions of known methods and techniques are omitted here.

Various modifications and variations can be made to this application by those skilled in the art without departing from the scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
