Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a bone surface hemostasis device. Background Technology

[0002] During orthopedic surgery, bleeding may occur from the patient's bone wound. At this time, medical staff need to apply bone wax to the patient's bone wound so that the bone wax can physically seal the blood vessels in the patient's bone wound to achieve the purpose of stopping the bleeding.

[0003] During the application of bone wax, medical staff usually need to wear medical gloves and hold the bone wax to manually apply it to the patient's bone wound. Because the surface of bone wax is relatively smooth, it is difficult for medical staff to hold it steadily after wearing medical gloves, causing the bone wax to easily slip from their hands, making the application process inconvenient. In addition, the bone wax needs to be wrapped in the hand and heated to soften it before application, which further complicates the application process. Utility Model Content

[0004] This invention provides a bone surface hemostasis device, which solves the technical problems of existing technologies that require manual application to the patient's bone wound surface, causing the bone wax to easily slip from the hand, and requiring the bone wax to be wrapped in the hand and heated to soften it before application, making the application process inconvenient.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A bone surface hemostasis device includes an extrusion cylinder, a piston slidably disposed inside the extrusion cylinder, a threaded sleeve rotatably connected to the rear end of the extrusion cylinder, a set of screws threadedly connected to the threaded sleeve inside the extrusion cylinder, the ends of the screws being fixedly connected to the piston, a handle connected to the rear end of the extrusion cylinder, a power component for driving the threaded sleeve to rotate being disposed between the handle and the threaded sleeve, a heating sleeve nested at the front end of the extrusion cylinder, a heat-conducting layer disposed inside the heating sleeve, the inner surface of the heat-conducting layer extending into the interior of the extrusion cylinder, and an electric heating wire surrounding the heat-conducting layer disposed inside the heating sleeve.

[0006] Furthermore, the power assembly includes a motor installed inside the grip, a first bevel gear connected to one end of the motor output shaft, and a second bevel gear connected to the threaded sleeve and meshing with the first bevel gear.

[0007] Furthermore, a guide slide rod is fixedly connected to the piston, and a guide hole is provided on the rear side of the extrusion cylinder for the guide slide rod to pass through.

[0008] Furthermore, the bone surface hemostasis device also includes a set of caps that are threadedly engaged with the front end of the extrusion cylinder, and the caps are provided with extrusion holes.

[0009] Furthermore, a connecting strap is attached to the cover, and a dust cap is attached to the end of the connecting strap.

[0010] Furthermore, a lighting head is installed on the extrusion cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the combined action of piston, screw sleeve, screw and power component, bone wax can be automatically extruded from the front end of the extrusion cylinder. Therefore, medical staff only need to hold the handle and align the front end of the extrusion cylinder with the patient's bone wound. Moreover, the heating sleeve at the front end of the extrusion cylinder can heat the front end of the extrusion cylinder, so that the bone wax can be effectively heated and softened before extrusion, making it easier to apply to the patient's bone wound. This makes the bone wax application process more convenient and easier to operate. Attached Figure Description

[0017] Please see Figure 1-5A bone surface hemostasis device includes an extrusion cylinder 1, the interior of which is used to fill bone wax to be applied. A piston 2 is disposed inside the extrusion cylinder 1, and the piston 2 is in contact with the inner wall of the extrusion cylinder 1, allowing it to slide back and forth within the cylinder. The bone wax inside the extrusion cylinder 1 is positioned at the front end of the piston 2. When the piston 2 slides forward, it pushes the bone wax inside the extrusion cylinder 1 towards the front end of the piston 2. A threaded sleeve 3 is rotatably connected to the rear end of the extrusion cylinder 1. The extrusion cylinder 1 also has a... The threaded sleeve 3 is threadedly connected to a set of screws 4. The end of the screws 4 is fixedly connected to the piston 2. When the threaded sleeve 3 rotates relative to the screws 4, the threaded sleeve 3 drives the screws 4 to move back and forth inside the extrusion cylinder 1. At this time, the piston 2 slides back and forth inside the extrusion cylinder 1 under the drive of the screws 4. The rear end of the extrusion cylinder 1 is also connected to a handle 5 for easy gripping by medical personnel. A power assembly is provided between the handle 5 and the threaded sleeve 3. The power assembly includes a motor 6 installed inside the handle 5. A first bevel gear 7 is connected to one end of the output shaft of the motor 6, and a second bevel gear 8 is connected to the threaded sleeve 3 and meshes with the first bevel gear 7. After the motor 6 is started, the output shaft of the motor 6 will drive the first bevel gear 7 to rotate. At the same time, the rotation of the first bevel gear 7 will drive the second bevel gear 8 to rotate, thereby causing the threaded sleeve 3 to rotate under the drive of the second bevel gear 8. This drives the piston 2 inside the extrusion cylinder 1 to slide back and forth, extruding bone wax from the front end of the extrusion cylinder 1. The front end of the extrusion cylinder 1 is nested with a heating sleeve 9. The heating sleeve 9 has a heat-conducting layer 10 inside, and the inner surface of the heat-conducting layer 10 extends into the interior of the extrusion cylinder 1. The heating sleeve 9 also has an electric heating wire 11 surrounding the heat-conducting layer 10. When the electric heating wire 11 is energized, it can convert electrothermal energy into thermal energy to generate a certain amount of heat. The electric heating wire 11 can then transfer the heat through the heat-conducting layer 10 to the front end of the extrusion cylinder 1, thereby heating the bone wax at the front end of the extrusion cylinder 1. When the bone wax is extruded from the front end of the extrusion cylinder 1, it is easier to apply the softened bone wax to the patient's bone wound.

[0018] During use, medical staff hold handle 5, align the front end of extrusion cylinder 1 with and attach it to the patient's bone wound. Then, the drive assembly controls the rotation of the screw sleeve 3, causing it to drive the screw 4 forward. During this process, the screw 4 drives the piston 2 to slide forward inside the extrusion cylinder 1, automatically extruding the bone wax from its front end. Simultaneously, the heating wire 11 inside the heating sleeve 9 generates heat, which is transferred to the extrusion cylinder 1 through the heat-conducting layer 10. This heats the bone wax at the front end of the extrusion cylinder 1, allowing it to be extruded in a softened state and applied to the patient's bone wound. The heating sleeve 9 can also be set with a temperature control. A temperature sensor, connected to the power supply for 11, is used to control the temperature within 09 within the required range, thereby providing constant temperature heating for the bone wax. In summary, during the application of bone wax, the piston 2, screw sleeve 3, screw 4, and power assembly work together to automatically extrude the bone wax from the front end of the extrusion cylinder 1. Therefore, medical staff only need to hold the handle 5 and align the front end of the extrusion cylinder 1 with the patient's bone wound. Furthermore, the heating sleeve 9 at the front end of the extrusion cylinder 1 can heat the front end of the extrusion cylinder 1, effectively softening the bone wax before extrusion, making it easier to apply to the patient's bone wound. This makes the bone wax application process more convenient and easier to operate.

[0019] For further details, please refer to Figure 1-5 A guide slide rod 12 is fixedly connected to the piston 2. A guide hole 13 is provided on the rear side of the extrusion cylinder 1 for the guide slide rod 12 to pass through. When the piston 2 slides back and forth inside the extrusion cylinder 1, the guide slide rod 12 passing through the guide hole 13 can guide the sliding of the piston 2, so that the piston 2 will not deflect during the sliding process, thereby ensuring the stability of the piston 2 during the sliding process.

[0020] For further details, please refer to Figure 1-5The bone surface hemostasis device also includes a set of caps 14, which can be threadedly connected to the front end of the extrusion cylinder 1. The caps 14 are provided with extrusion holes 15. The caps 14 can be installed onto or removed from the front end of the extrusion cylinder 1 by rotation. Installing the caps 14 onto the front end of the extrusion cylinder 1 prevents the bone wax inside the extrusion cylinder 1 from slipping out. When the piston 2 slides forward, the bone wax at the front end of the extrusion cylinder 1 can be extruded from the extrusion holes 15. Removing the caps 14 prevents the bone wax from slipping out. After being removed from the front end of the extrusion cylinder 1, bone wax can be added to the inside of the extrusion cylinder 1. In addition, a connecting strip 16 is connected to the cap 14, and a dust cap 17 is connected to the end of the connecting strip 16. The dust cap 17 can cover the extrusion hole 15. When the device is not in use, it can prevent external dust or water from entering the extrusion cylinder 1 through the extrusion hole 15, thus avoiding contamination of the bone wax inside the extrusion cylinder 1. The dust cap 17 is connected to the cap 14 through the connecting strip 16 to prevent it from being lost.

[0021] For further details, please refer to Figure 1-5 The extrusion cylinder 1 is equipped with a lighting head 18. During the application of bone wax, the lighting head 18 can illuminate the bone wound, allowing medical staff to see the condition of the patient's bone wound more clearly and making the operation easier.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
