[0002] In the field of medical device packaging, as a precision and commonly used medical device, the packaging process of a surgical electrocautery knife not only requires high efficiency and automation, but also needs to ensure sterility, safety and good protection to prevent contamination or damage during transportation, storage and use. Traditional packaging methods for surgical electrocautery knives often rely on manual operation, which is not only inefficient, but also difficult to ensure the consistency and sterility standards of packaging, increasing medical risks.

[0003] With the rapid development of automation technology, especially its extensive application in the fields of industrial automation and intelligent manufacturing, it is particularly important to develop a mechanism that can automatically, efficiently and safely complete the packaging task of surgical electrocautery knives. Although traditional packaging machinery has improved packaging efficiency to a certain extent, it is often designed for products with specific shapes and sizes, and its adaptability and packaging effect for medical devices such as surgical electrocautery knives with specific shapes and sensitivities are limited. Summary of the Utility Model

[0004] The utility model provides a packaging mechanism for a surgical electrocautery knife to solve the problem that traditional packaging equipment is not suitable for packaging surgical electrocautery knives.

[0005] To alleviate the above technical problems, the technical solution provided by the utility model lies in:

[0006] A packaging mechanism for a surgical electrocautery knife includes a conveying assembly. The conveying assembly includes a workbench and a conveyor belt arranged on the upper part of the workbench. A plurality of rotatably arranged toothed rings are arrayedly connected to the conveying surface of the conveyor belt, and the surgical electrocautery knife is installed in the middle of the toothed ring.

[0007] A mold is arranged on the workbench. The mold is composed of two movable molds. A groove matching with the surgical electrocautery knife is commonly opened on the two movable molds. An encapsulation film is arranged between the two movable molds. When the surgical electrocautery knife moves to the middle position between the two movable molds, the conveyor belt stops running, and the two movable molds approach each other to press and cut the two encapsulation films, so that the encapsulation film packages the surgical electrocautery knife.

[0008] Furthermore, two fixing frames are symmetrically connected to both sides of the workbench, hydraulic rods are connected to both fixing frames, and the two movable molds are respectively connected to the output ends of the two hydraulic rods.

[0009] Furthermore, a storage roller and a release roller are respectively connected to the upper and lower parts of the fixing frame, and the packaging film is driven between the storage roller and the release roller;

[0010] Two guiding rollers are also respectively connected to the upper and lower parts of the fixing frame. The packaging film bypasses the two guiding rollers and is driven between the storage roller and the release roller. When the hydraulic rod shortens, the moving die is located between the two guiding rollers, the storage roller, and the release roller.

[0011] Furthermore, hot melt strips are arranged at the edges of the grooves on the two moving dies. After the two moving dies approach each other, the hot melt strips are activated so that the packaging film is cut and bonded.

[0012] Furthermore, air inlets are formed on the two moving dies. After the two moving dies approach each other, air is injected into the grooves of the moving dies so that the packaging film closely adheres to the surgical electrotome.

[0013] Furthermore, ultrasonic welding heads are arranged at the edges of the grooves on the two moving dies. A blade is arranged outside the ultrasonic welding head. A storage groove cooperating with the blade is formed on the moving die. The blade slides in the storage groove, and a spring is connected between the blade and the storage groove.

[0014] Furthermore, a cutting mark is arranged on the packaging film.

[0015] Furthermore, a through groove is formed on the packaging film, and the cutting mark is connected to the through groove.

[0016] Furthermore, the conveying assembly further includes two rotating seats symmetrically connected to both sides of the workbench surface. Rotating rollers are connected to the two rotating seats, and the conveyor belt is drivingly connected between the two rotating rollers.

[0017] Furthermore, a motor is connected to the workbench, and one of the rotating rollers is connected to the output end of the motor.

[0018] The beneficial effects of the present utility model are analyzed as follows:

A mold is arranged on the workbench. The mold is composed of two movable molds. A groove matching with the surgical electrotome is jointly opened on the two movable molds. An encapsulation film is arranged between the two movable molds. When the surgical electrotome moves to the middle position between the two movable molds, the conveyor belt stops running, and the two movable molds approach each other to press and cut the two encapsulation films together, so that the encapsulation film packages the surgical electrotome.

[0020] When the surgical electrotome is at the groove position corresponding to the two movable molds, it stops moving and maintains its position. Then the two movable molds approach each other. When the two movable molds approach each other, they can synchronously push the two encapsulation films located on both sides of the surgical electrotome, so that both encapsulation films contact the surgical electrotome. Then the hydraulic rod continues to extend, so that the two encapsulation films contact each other. As the pressure increases with the extension of the hydraulic rod, the encapsulation film packages the surgical electrotome. Brief Description of the Drawings

[0032] Example 1, as Figures 1 - 5As shown in the figure, a packaging mechanism for a surgical electrotome includes a conveying assembly 100. The conveying assembly 100 includes a workbench 110 and a conveyor belt 140 arranged on the upper part of the workbench 110. A plurality of rotatably arranged toothed rings 160 are array - connected on the conveying surface of the conveyor belt 140, and the surgical electrotome is installed in the middle of the toothed ring 160. A mold 230 is arranged on the workbench 110. The mold 230 is composed of two movable molds 232. A groove matching with the surgical electrotome is commonly opened on the two movable molds 232. A packaging film 240 is arranged between the two movable molds 232. When the surgical electrotome moves to the middle position between the two movable molds 232, the conveyor belt 140 stops running, and the two movable molds 232 approach each other to press and cut the two packaging films 240, so that the packaging film 240 packages the surgical electrotome.

[0033] The working mechanism of the packaging mechanism provided in this embodiment:

[0034] The encapsulation assembly 200 is used to encapsulate the surgical electrotome and is composed of a fixed frame 210, a hydraulic rod 220, a mold 230, an air inlet 231, a movable mold 232, a packaging film 240, a through - slot 241, a cutting mark 242, a cutting hole 243, a storage roller 250, a release roller 260, and a guiding roller 270. When the surgical electrotome is at the groove position corresponding to the two movable molds 232, it stops moving and maintains its position. Then the two movable molds 232 approach each other. When the two movable molds 232 approach each other, they can synchronously push the two packaging films 240 located on both sides of the surgical electrotome, so that the two packaging films 240 both contact the surgical electrotome. Then the hydraulic rod 220 continues to extend, so that the two packaging films 240 contact each other. As the pressure increases with the extension of the hydraulic rod 220, the packaging film 240 packages the surgical electrotome.

[0035] In an alternative embodiment of this example, a more preferred way is:

[0036] Two fixed frames 210 are symmetrically connected to both sides of the workbench 110. Hydraulic rods 220 are connected to both fixed frames 210, and the two movable molds 232 are respectively connected to the output ends of the two hydraulic rods 220.

[0037] The setting of the fixed frame 210 enables the installation of the hydraulic rod 220. At the same time, the fixed frame 210 supports the two movable molds 232. When the two hydraulic rods 220 extend synchronously, the two movable molds 232 can approach each other synchronously.

[0038] In an alternative embodiment of this example, a more preferred way is:

[0039] The upper and lower parts of the fixing frame 210 are respectively connected with a storage roller 250 and a release roller 260, and the encapsulation film 240 is driven between the storage roller 250 and the release roller 260; the upper and lower parts of the fixing frame 210 are also respectively connected with two guiding rollers 270, the encapsulation film 240 bypasses the two guiding rollers 270 and is driven between the storage roller 250 and the release roller 260. When the hydraulic rod 220 shortens, the moving die 232 is located between the two guiding rollers 270, the storage roller 250 and the release roller 260.

[0040] When the surgical electrotome is encapsulated, a cutting hole 243 is formed on the encapsulated encapsulation film 240, and at this time the encapsulation film 240 is not disconnected. Therefore, when the storage roller 250 rotates, it can re-tract the uncut encapsulation film 240 on the release roller 260 to the middle position of the grooves of the two moving dies 232 to prepare for the next encapsulation. The rotation timing of the storage roller 250 and the release roller 260 is within the time interval of the contraction and extension of the two hydraulic rods 220, and the encapsulated surgical electrotome can be removed from the toothed ring 160.

[0041] In an alternative embodiment of the present embodiment, preferably:

[0042] Hot melt strips are arranged at the edges of the grooves on the two moving dies 232. After the two moving dies 232 approach each other, the hot melt strips are activated so that the encapsulation film 240 is cut and adhered.

[0043] The encapsulation film 240 completely adheres to the range of the blade head of the surgical electrotome. Subsequently, the hot melt strips on the moving die 232 are activated, so that the two encapsulation films 240 are mutually adhered, and at the same time, the heat generated by the hot melt strips disconnects the encapsulation film 240 at the cutting mark 242.

[0044] In an alternative embodiment of the present embodiment, preferably:

[0045] Air inlets 231 are formed on both of the two moving dies 232. After the two moving dies 232 approach each other, air is injected into the grooves of the moving dies 232 through the air inlets 231 so that the encapsulation film 240 closely adheres to the surgical electrotome.

[0046] When the two moving dies 232 approach each other, they can synchronously push the two encapsulation films 240 located on both sides of the surgical electrotome, so that both of the two encapsulation films 240 contact the surgical electrotome. Subsequently, the hydraulic rod 220 continues to extend, so that the two encapsulation films 240 contact each other. At this time, the two moving dies 232 are mutually pressed. Subsequently, an external air pump injects air into the grooves of the moving dies 232 through the air inlets 231, so that the encapsulation film 240 is closely adhered to the surgical electrotome after being extruded by the gas. After injecting air for a period of time, the encapsulation film 240 completely adheres to the range of the blade head of the surgical electrotome.

[0047] In an alternative embodiment of the present embodiment, preferably:

[0048] A cutting mark 242 is provided on the encapsulation film 240, a through groove 241 is formed on the encapsulation film 240, and the cutting mark 242 is connected to the through groove 241.

[0049] When the surgical electrotome is encapsulated, a cutting hole 243 is formed on the encapsulated encapsulation film 240. At this time, the encapsulation film 240 is not disconnected. Therefore, when the storage roller 250 rotates, the uncut encapsulation film 240 on the release roller 260 can be re-tracted to the middle position of the grooves of the two movable molds 232 to prepare for the next encapsulation.

[0050] In an optional manner of this embodiment, preferably:

[0051] The conveying assembly 100 further includes two turntables 120, the two turntables 120 are symmetrically connected to both sides of the tabletop of the workbench 110, a roller 130 is connected to each of the two turntables 120, the conveyor belt 140 is drivingly connected between the two rollers 130, and a motor 150 is connected to the workbench 110. One of the rollers 130 is connected to the output end of the motor 150.

[0052] An induction switch for controlling the second motor 150 is provided on the fixed frame 210. When the induction switch senses that the surgical electrotome moves to the middle position between the two movable molds 232 of the mold 230, it controls the motor 150 to stop running, so that the surgical electrotome stops between the two movable molds 232.

[0053] In Embodiment 2, the difference from Embodiment 1 is that ultrasonic welding heads are provided at the edges of the grooves on the two movable molds 232, blades are provided outside the ultrasonic welding heads, receiving grooves matching the blades are formed on the movable molds 232, the blades slide in the receiving grooves, and a spring is connected between the blades and the receiving grooves.

[0054] The hot melt strips on the movable molds 232 can also be replaced by ultrasonic welding heads. When using the ultrasonic welding heads, the ultrasonic welding heads should be arranged inside the positions of the corresponding movable molds 232 of the cutting marks 242. Blades are arranged on one or two of the movable molds 232 corresponding to the cutting marks 242. The blades are connected to the movable molds 232 through springs, and receiving grooves matching the blades are formed on the movable molds 232, so that when the two movable molds 232 are pressed against each other, the blades can retract into the receiving grooves without affecting the welding of the ultrasonic welding heads. And the springs between the blades and the movable molds 232 should have sufficient elasticity so that the blades can provide sufficient cutting force for the encapsulation film 240 and at the same time do not affect the retraction of the blades.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.
