Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of isolation film cutting, and particularly relates to a film cutter for silicone rubber impression. BACKGROUND

[0002] In the two-step method of taking a silicone rubber impression currently used in clinical practice, an equal amount of heavy impression material is mixed at the time required by the manufacturer, and then an isolation film is placed on the tray to adhere to the impression material and maintain the position of the isolation film, and then the tray is placed in the patient's mouth to complete the initial impression. In this operation, the original method uses scissors to cut the appropriate film. Since scissors are sharp tools, there may be a risk of hospital infection during use, and the integrity of the cut cannot be guaranteed when the scissors are cut, which can easily cause the cut to be unsightly. In addition, the isolation film is also likely to stick to the isolation film roll after being cut, and the operator needs to find the cut again during the next use, thereby increasing the time for cutting the isolation film. SUMMARY

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] like Figures 1-4 As shown, a film cutter for silicone rubber impression includes a storage cylinder 1, a release membrane 2 and a cutting blade 3. The inner cavity of the storage cylinder 1 is provided with a storage cavity 4 for placing the release membrane 2. The surface of the storage cylinder 1 is provided with a notch 5 communicating with the storage cavity 4 along its own length direction for the release membrane 2 to be pulled out. The cutting blade 3 is slidably connected to the storage cylinder 1 located on one side of the notch 5 to cut the release membrane 2 pulled out of the notch 5.

[0024] Among them, elastic extrusion members 6 are provided on both sides of the notch 5. The two elastic extrusion members 6 approach each other under their own elastic force and squeeze and clamp the isolation membrane 2 that is pulled out of the notch 5, so as to prevent the isolation membrane 2 from being recycled into the storage cavity 4 after being cut.

[0025] When using the device, the user needs to manually pull out the isolation membrane 2 protruding from the notch 5. After pulling out the isolation membrane 2, it is cut off by the built-in cutting blade 3. Since the isolation membrane 2 in the storage cavity 4 is placed in a roll and the isolation membrane roll needs to be used multiple times, in order to prevent the cutting blade 3 from cutting the isolation membrane 2 and then recycling it, because once recycled, the user will not be able to manually pull out the isolation membrane 2 again when using it next time, the elastic squeezing member 6 is set to squeeze and fix the isolation membrane after it is pulled out.

[0026] The device cuts the entire separator membrane with its own cutting blade, eliminating the need for scissors or other instruments, while ensuring the integrity of the separator membrane. At the same time, the cut separator membrane is prevented from being recycled into the inner cavity of the storage cylinder by the elastic extrusion component, so as to facilitate subsequent continuous use.

[0027] Specifically, such as Figure 1 and Figure 4As shown, the elastic extrusion piece 6 includes two mounting seats 61 and a roller shaft 62, the two mounting seats 61 are fixedly connected at the top and bottom of the notch 5 respectively, a sliding groove 63 is formed on the side wall of the side of the two mounting seats 61 close to each other, a sliding block 64 is slidably connected in the inner cavity of the two sliding grooves 63, the two ends of the roller shaft 62 are correspondingly rotatably connected on the two sliding blocks 64, a reset spring 65 is fixedly connected in the inner cavity of the two sliding grooves 63, and the end of the reset spring 65 away from the sliding groove 63 is fixedly connected with the sliding block 64. Under the elastic force of the reset spring 65, the roller shaft 62 is driven to move towards the middle position of the notch 5.

[0028] In the initial state of the two elastic extrusion pieces 6, the two roller shafts 62 can approach and contact each other under the elastic force of the reset spring 65, and the isolation film 2 can pass between the two roller shafts 62. Since the two roller shafts 62 are rotatable, the movement of the isolation film 2 will not be interfered.

[0029] Further, as shown in the drawings, Figures 1-3 The surface of the storage cylinder 1 on one side of the notch 5 is provided with a slot 7 for sliding of the cutting knife 3, and the surface of the storage cylinder 1 on the other side of the notch 5 is provided with a groove 8 for insertion of the cutting knife 3.

[0030] The width of the slot 7 is greater than the width of the cutting knife 3, that is, the cutting knife 3 can be completely accommodated in the slot 7, and when the cutting knife 3 covers the notch 5 and is inserted into the groove 8, a part of the cutting knife 3 still remains in the slot 7. This can ensure that the isolation film 2 is completely cut off, and the movable cutting knife 3 is not easy to hurt people.

[0031] Among them, the cutting knife 3 and the slot 7 can slide through the sliding rail or the sliding groove.

[0032] Since the isolation film 2 needs to be replaced in time after being used up, the entire storage cylinder 1 needs to be detachable.

[0033] Specifically, as shown in the drawings, Figures 1-2 The storage cylinder 1 includes a cylinder body 11 and cylinder covers 12 threadedly connected at the openings of both ends of the cylinder body 11, one of the cylinder covers 12 is fixedly connected with a fixed rod 13 extending into the inner cavity of the cylinder body 11, the other end of the fixed rod 13 away from the fixed point can abut against the other cylinder cover 12, and the isolation film 2 is rotatably sleeved on the fixed rod 13.

[0034] The notch 5 is distributed along the length direction of the cylinder body 11.

[0035] The detachable storage cylinder 1 can directly rotate down the cylinder cover 12 after the isolation film 2 is used up, and the new isolation film 2 can be inserted into the fixed rod 13.

[0036] Further, as shown in the drawings, Figures 1-2As shown, the length of the notch 5 is the same as the length of the barrel 11, so that the isolation film 2 is conveniently pulled out from the notch 5.

[0037] The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements should also be considered to fall within the protection scope of the present application.
