Technical Field

[0001] This utility model relates to the technical field of ultrasonic scalpel rods, and more particularly to a device for improving adhesive overflow in ultrasonic scalpel rods. Background Technology

[0002] Due to its advantages such as less bleeding and less damage to surrounding tissues, ultrasonic scalpels are widely used in clinical surgery. Currently, ultrasonic scalpels have become routine equipment for many surgeries, including ophthalmic surgery, neurosurgery, urological surgery, and plastic and cosmetic surgery. With the continuous development of technology, the performance and functions of ultrasonic scalpels are also constantly improving, such as adding more surgical modes and improving cutting efficiency. However, the structure of the mold parts does not meet the sealing requirements, resulting in excessive glue overflow.

[0003] In addition, existing molds lack a cooling system, cannot cool the molds quickly, and have high thermal stress. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an ultrasonic scalpel blade overflow improvement device. It has a simple structure and is easy to operate. It uses the closed structure of the mold parts to prevent overflow. By accelerating the cooling of the mold, the production cycle can be shortened, thereby improving production efficiency. The faster cooling of the mold can reduce the thermal stress of the mold.

[0005] To achieve the above objectives, this utility model provides a device for improving the overflow of adhesive when using an ultrasonic scalpel shaft, comprising: a cooling shell, a first water tank fixedly connected to the outer surface of the cooling shell, a water pipe fixedly connected to the outer surface of the first water tank, the outer surface of the water pipe fixedly connected to the cooling shell, a second water tank fixedly connected to one end of the water pipe, a temperature equalization shell detachably connected to the inner surface of the cooling shell, a mold installed on the inner wall of the temperature equalization shell, the mold comprising a first half-mold, a second half-mold detachably connected to the inner surface of the first half-mold, and the working surfaces of the first half-mold and the second half-mold fitting together to form a sealed cavity.

[0006] Furthermore, a hydraulic rod is fixedly connected to the lower bottom wall of the temperature equalization shell, and an ejector plate is fixedly connected to the output end of the hydraulic rod. The mold is ejected through the ejector plate, making it convenient for people to remove the mold.

[0007] Furthermore, the upper surface of the ejector plate abuts against the mold, and the outer surface of the mold is movably connected to the temperature equalization shell. The mold cools down uniformly within the temperature equalization shell, thus accelerating the cooling of the mold.

[0008] Furthermore, the outer surface of the second water tank is fixedly connected to the cooling shell, and both the second and first water tanks are equipped with water pumps to cool the mold by circulating water, thereby improving cooling efficiency.

[0009] Furthermore, the cooling shell has through holes inside, and the inner wall of the through holes is fixedly connected to the water pipes, making the overall structure more stable.

[0010] Furthermore, the outer surfaces of the first and second half molds are movably connected to the temperature-equalizing shell, and the lower surfaces of the first and second half molds are in contact with the ejector plate, which can more stably fix the mold.

[0011] Furthermore, the cooling shell, the heat spreader shell, and the mold are all made of brass, and the water pipes are heat dissipation copper pipes, making the cooling effect more uniform.

[0012] Furthermore, the ejector plate is installed inside the temperature-equalizing shell, and the outer surface of the ejector plate is slidably connected to the temperature-equalizing shell, which can more stably fix the mold and make it easier to remove the mold.

[0013] In summary, compared with the prior art, the ultrasonic scalpel handle adhesive overflow improvement device of this utility model has at least the following beneficial effects:

[0014] 1. After the first half mold and the second half mold of this utility model are placed into the temperature equalization shell, it can ensure that the first half mold and the second half mold are tightly attached together, so that the working surfaces of the first half mold and the second half mold are in contact to form a closed cavity. The use of mold parts structure to close the cavity prevents glue overflow, reduces the glue peeling process, and saves labor costs.

[0015] 2. By accelerating the cooling of the mold, the production cycle can be shortened, thereby improving production efficiency. Faster mold cooling can reduce the thermal stress of the mold. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See below. Figures 1-4 This invention provides a detailed description of the ultrasonic scalpel shaft adhesive overflow improvement device.

[0024] like Figure 1-4 As shown, the ultrasonic scalpel barrel adhesive overflow improvement device of this utility model includes: a cooling shell 1, which serves a cooling function to accelerate the cooling of the mold 5; a first water tank 2 is fixedly connected to the outer surface of the cooling shell 1 for storing cooling water, which is circulated to the cooling shell 1 by a water pump for cooling effect; a water pipe 6 is fixedly connected to the outer surface of the first water tank 2 for connecting the cooling shell 1, the first water tank 2, and the second water tank 3 for transporting cooling water; the outer surface of the water pipe 6 is fixedly connected to the cooling shell 1, and one end of the water pipe 6 is fixedly connected to the second water tank 3 for storing cooling water, which is circulated to the cooling shell 1 by a water pump. The cooling shell 1 has a detachable heat exchange shell 4 connected to its inner surface to maintain a uniform temperature of the mold 5. The mold 5 is installed on the inner wall of the heat exchange shell 4. The mold 5 is made of rubber-coated ultrasonic scalpel rod. The mold 5 includes a first half mold 501, which together with the second half mold 502 forms part of the mold 5. The inner surface of the first half mold 501 is detachably connected to the second half mold 502, which together with the first half mold 501 forms part of the mold 5. The bottom wall of the heat exchange shell 4 is fixedly connected to a hydraulic rod 8 to control the extension and retraction of the ejector plate 7. The output end of the hydraulic rod 8 is fixedly connected to the ejector plate 7. After the mold 5 has cooled down, the mold 5 is ejected.

[0025] The upper surface of the ejector plate 7 abuts against the mold 5. The outer surface of the mold 5 is movably connected to the heat spreader shell 4. The outer surface of the second water tank 3 is fixedly connected to the cooling shell 1. Water pumps are installed inside both the second water tank 3 and the first water tank 2. A through hole is provided inside the cooling shell 1, and the inner wall of the through hole is fixedly connected to the water pipe 6. The outer surfaces of the first half mold 501 and the second half mold 502 are movably connected to the heat spreader shell 4. The lower surfaces of the first half mold 501 and the second half mold 502 are in contact with the ejector plate 7. The working surfaces of the first half mold 501 and the second half mold 502 are in contact to form a sealed cavity. Each of the first half mold 501 and the second half mold 502 is provided with a half connecting channel for forming the connecting flow channel 10. The colloid fills the sealed cavity through the connecting flow channel 10. Overflow grooves 9 are also provided on both sides of the second half mold 502. After the first half mold 501 and the second half mold 502 are placed into the temperature equalization shell 4, it is ensured that the first half mold 501 and the second half mold 502 are tightly attached together, so that the working surfaces of the first half mold 501 and the second half mold 502 are in contact to form a sealed cavity. The ejector plate 7 is controlled by the hydraulic rod 8 to extend and retract to eject the mold 5, making mold removal convenient.

[0026] The cooling shell 1, the heat spreader shell 4, and the mold 5 are all made of brass. The water pipe 6 is a heat dissipation copper pipe. The ejector plate 7 is installed inside the heat spreader shell 4, and the outer surface of the ejector plate 7 is slidably connected to the heat spreader shell 4.

[0027] Below, refer to Figures 1 to 4 Based on the above description of structural features, the working principle of the ultrasonic scalpel handle adhesive overflow improvement device of this utility model is described as follows:

[0028] After the mold is placed in the temperature-equalizing shell 4 and closed, the working surfaces of the first half mold 501 and the second half mold 502 fit together to form a sealed cavity. The colloid is injected into the conveying channel through the fluid injection gun. The colloid is then transported to the connecting channel 10 through the conveying channel and filled into the sealed cavity (fluid forming cavity) through the connecting channel 10. By adjusting the amount and pressure of the injected colloid, the colloid fills the sealed cavity and the overflow groove 9 to achieve the overmolding. When the ultrasonic scalpel bar is removed, the thickness of the colloid in the overflow groove 9 (0.4 mm) is greater than the thickness of the burr (0.015 mm), which allows the burr to separate at the overflow groove 9, achieving the improvement goal and realizing the overmolding of the scalpel bar.

[0029] When mold 5 needs cooling, a water pump in the first water tank 2 injects cooling water into the water pipe 6. The water in the water pipe 6 is then fed into the second water tank 3. As it is fed into the second water tank 3, it carries away heat from the cooling shell 1. Because the cooling shell 1, the heat spreader shell 4, and the mold 5 are all made of brass, the temperature of the mold 5 will also decrease. The above description is merely a specific embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any modifications or substitutions that can be understood by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of this utility model.
