Description

Technical Field

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

[0002] When assembling the ultrasonic scalpel tip assembly, the rubber-coated scalpel rod, sleeve, trigger, and other accessories must first be assembled. The assembled components are then placed into the handle housing to be pressed, and the handle housing is then pressed to complete the assembly of the ultrasonic scalpel tip assembly. However, the existing pressing assembly process mainly relies on the assembler manually pressing the handle housing and then using a rubber mallet to tap the handle housing to achieve tightness. This not only easily leads to deformation of the handle housing due to uneven force on various parts of the handle housing, causing damage to its internal structure, thus reducing the assembly pass rate and assembly quality, but also makes the assembly quality overly dependent on the assembler's operating experience, making it difficult to ensure assembly quality and efficiency. Utility Model Content

[0031] 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.

[0032] 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.

[0033] like Figure 1 and Figure 2 As shown, this utility model relates to a tooling mechanism for assembling an ultrasonic scalpel tip assembly. The ultrasonic scalpel tip assembly includes a handle housing 10; a trigger 20, a sleeve 30, and a rubber-coated scalpel bar 50 assembled within the handle housing 10; and a clamp 40 mounted on the sleeve 30 at one end away from the handle housing 10. The tooling mechanism includes a fixed bracket 1; a contoured mounting base 2, which is disposed on the fixed bracket 1 for placing the ultrasonic scalpel tip assembly to be assembled; a power component 3, which is disposed on the fixed bracket 1 and located above the contoured mounting base 2; and a pressing cover plate 4, which is connected to the power component 3 and can press the handle housing 10 on the ultrasonic scalpel tip assembly on the contoured mounting base 2 under the drive of the power component 3.

[0034] This invention places and confines the ultrasonic scalpel head assembly to be assembled within a contour-following mounting base. A power component drives a pressing cover plate to press down on the contour-following mounting base, ensuring that the pressing force of the pressing cover plate is evenly transmitted to the handle housing of the ultrasonic scalpel head assembly. This not only avoids the risk of deformation of the handle housing due to uneven force during the pressing process, which could damage the internal structure of the handle housing, but also reduces the reliance on the operator's experience, thereby improving assembly quality and efficiency.

[0035] As a preferred embodiment, such as Figure 1 and Figure 2 As shown, the contour mounting base 2 includes a contour base 21 fixedly mounted on the fixed bracket 1; and a contour cover 22 overlapping the contour base 21, wherein a cavity for accommodating the handle housing 10 on the ultrasonic scalpel head assembly is formed between the contour base 21 and the contour cover 22.

[0036] As another preferred implementation, such as Figures 2 to 5As shown, the contoured base 21 has a first groove 211 for placing the first housing 101 of the handle housing 10, and the contoured top cover 22 has a second groove 221 for placing the second housing 102 of the handle housing 10. The first groove 211 and the second groove 221 cooperate to form a cavity for accommodating the handle housing 10 on the ultrasonic scalpel head assembly to be assembled. Specifically, the outer contours of the first groove 211 and the second groove 221 are adapted to the corresponding outer contours of the first housing 101 and the second housing 102, so that the first housing 101 and the second housing 102 can fit together with the first groove 211 and the second groove 221, ensuring that the handle housing 10 is subjected to uniform force during the pressing process and will not shift. This further avoids the risk of damage to the internal structure of the handle housing. The contoured base 21 is provided with multiple platforms. The contoured top cover 22 has multiple protrusions 222 that are adapted to each step 212. Each protrusion 222 overlaps the corresponding step 212. Specifically, the number of steps 212 and protrusions 222 is the same, which can be at least two or more, preferably four. Each step 212 has a first wedge-shaped surface 2121, and each protrusion 222 has a second wedge-shaped surface 2221 that fits against the first wedge-shaped surface 2121. Specifically, the first wedge-shaped surface 2121 and the second wedge-shaped surface 2221 are inclined surfaces with complementary inclination angles. The first wedge-shaped surface 2121 is used to guide the second wedge-shaped surface 2221 to move downward along the mating surface of the first wedge-shaped surface 2121 and the second wedge-shaped surface 2221 when the contoured top cover 22 is subjected to force and moves downward, further ensuring that the handle housing 10 is subjected to uniform and stable force during the pressing process and avoiding the risk of displacement.

[0037] It should be noted that by installing the first housing 101 of the handle housing 10 on the ultrasonic scalpel head assembly into the first groove 211 of the contour base 21, and then pre-assembling the second housing 102 of the handle housing 10 with the first housing 101, the internal structures of the second housing 102 and the first housing 101 are aligned. Specifically, the internal structures of the second housing 102 and the first housing 101 are provided with corresponding holes and shafts. The second housing 102 and the first housing 101 are pre-assembled by using a hole-shaft connection. Then, the second groove 221 of the contour cover 22 is placed on the second housing 102 and fits against it. At the same time, the four protrusions 222 on the contour cover 22 overlap with the corresponding four steps 212 on the contour base 21, and the first wedge surface 2121 fits against the second wedge surface 2221. In order to reserve space The pressing space ensures assembly quality. Therefore, when the second groove 221 of the contoured top cover 22 is placed on the second housing 102 and fitted therewith, the first wedge surface 2121 and the second wedge surface 2221 are partially fitted together, that is, the tip of the protrusion 222 away from the contoured top cover 22 does not contact the bottom surface on the step 212, so there is still a certain distance between them. That is, the contoured base 21 and the contoured top cover 22 are not completely closed. As the pressing cover plate 4 is driven by the power component 3 to press down on the contoured top cover 22, it continues to move down along the fitting surface of the second wedge surface 2221 and the first wedge surface 2121 until the second wedge surface 2221 and the first wedge surface 2121 are completely fitted together, that is, the tip of the protrusion 222 away from the contoured top cover 22 contacts the bottom surface on the step 212, the pressing of the handle housing 10 is completed.

[0038] As another alternative implementation method.

[0039] Preferably, such as Figures 1 to 3 As shown, the contour-following mounting base 2 is also provided with a support assembly for supporting the sleeve 30 on the ultrasonic scalpel head assembly. The support assembly includes a fixed base 23 connected to the contour-following base 21 on the contour-following mounting base 2; and a slider 24 slidably disposed on the fixed base 23 for supporting the sleeve 30. Specifically, the slider 24 is provided with a long groove 241 adapted to the shape of the sleeve 30. Preferably, the slider 24 is made of an elastic material. The elastic properties of the slider 24 allow the sleeve 30 to be engaged in the long groove 241 on the slider 24, which facilitates further securing the handle shell of the ultrasonic scalpel head assembly before pressing, avoiding the risk of damage to the sleeve and the rubber-coated scalpel rod during the pressing process, thereby affecting the assembly quality of the ultrasonic scalpel head assembly.

[0040] Preferably, as shown in Figure 2 and Figure 3As shown, the fixed base 23 is provided with a sliding groove 231, and at least one slider 24 is provided on the sliding groove 231. Specifically, two sliders 24 are slidably mounted on the sliding groove 231. By adjusting the position of any one slider 24 or adjusting both sliders 24 simultaneously on the sliding groove 231, the distance between the two sliders 24 can be changed, so as to be able to adapt to support ultrasonic scalpel heads of different specifications, i.e. ultrasonic scalpel heads of different lengths, such as 14mm, 23mm, 36mm and 45mm.

[0041] Preferably, such as Figure 1 As shown, the fixed bracket 1 includes a base plate 11 on which a contoured fixed mounting base 2 is fixedly installed; a top plate 12 on which a power assembly 3 is fixedly installed; and a column 13 disposed between the base plate 11 and the top plate 12 and connected to the base plate 11 and the top plate 12 at both ends respectively. The pressing cover plate 4 is disposed between the top plate 12 and the base plate 11. Specifically, the space between the top plate 11 and the base plate 12 is formed for installing the contoured fixed mounting base 2 and accommodating the pressing cover plate 4.

[0042] Preferably, such as Figure 1 As shown, the power assembly 3 includes a cylinder 31, the fixed end 311 of which is mounted on the top plate 12, and its telescopic end (not shown) is fixedly connected to the pressing cover plate 4. Specifically, the cylinder 31 penetrates the top plate 12, and the fixed end 311 of the cylinder 31 extends away from the bottom plate 11, while the telescopic end of the cylinder extends towards the bottom plate 11; and a guide sleeve 32 fixedly mounted on the top plate 12. Specifically, there are multiple guide sleeves 32, preferably four, which are evenly arranged on the top plate 12 along the circumference of the cylinder 31; and A guide rod 33 passes through the guide sleeve 32 and is slidably disposed within the guide sleeve 32. One end of the guide rod 33 near the bottom plate 11 is fixedly connected to the pressing cover plate 4, and the other end of the guide rod 33 away from the bottom plate 11 extends away from the top plate 12. Specifically, there are multiple guide rods 33, the number of which is the same as the number of guide sleeves 32. By using the guide sleeve 32 to limit and guide the guide rod 33, the pressing cover plate 4 can be prevented from moving and deviating under the drive of the extension end of the cylinder 31, thereby improving the stability and quality of pressing the handle housing 10.
