Description

Technical Field

[0001] The invention relates to the technical field of bone grafting devices, in particular to a bone grafting device for orthopedics. Background Art

[0002] With the continuous development of social economy and the continuous advancement of modern science and technology, bone grafting devices, as an emerging medical device, are specially designed for repairing bone defects in orthopedic surgery. Their appearance not only improves the accuracy and safety of surgery, but also greatly shortens the patient's recovery time.

[0003] However, when traditional bone grafts are used in deeper surgical sites or those with poor lighting conditions, such as spinal surgery or deep bone defect repair, doctors can only rely on the overall lighting of the operating room, which may cause shadows in the surgical area and affect the doctor's observation of the details of the bone graft site. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides an orthopedic bone grafting device, which solves the problem of insufficient or uneven illumination of the traditional bone grafting device.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A bone grafting device for orthopedics, comprising a bone grafting tube body, a connecting tube is arranged in the middle of the front end of the outer wall of the bone grafting tube body, a feeding tube is arranged at the front end of the upper part of the outer wall of the connecting tube, a connecting cover is arranged at the upper end of the feeding tube, a connecting valve is connected through the upper end of the connecting cover, a piston is arranged inside the bone grafting tube body, and a push rod is fixedly connected to the upper end of the piston;

[0009] The upper end of the push rod is fixedly connected with a push handle, the upper parts of the front end and rear end outer walls of the bone grafting tube body are fixedly connected with a fixing plate, one side of the fixing plate at the rear end is engaged with a snap-on cover, four micro LED lamp beads are arranged around the lower end of the bone grafting tube body, the inner wall of the connecting tube is rotatably connected with a screw dragon, and a rotating disk is arranged at the front end of the connecting tube;

[0010] Through the above technical solution, some granular, powdered or viscous bone grafting materials are prone to blockage during transportation, and the spiral structure of the auger can effectively break up these materials and make them evenly distributed in the connecting tube and the bone grafting tube body, thereby keeping the transportation channel unobstructed.

[0011] Preferably, the rear end of the connecting tube is connected to the middle part of the front end of the bone grafting tube body, and the lower end of the feeding tube is connected to the upper part of the front end of the connecting tube;

[0012] Through the above technical solution, this connection method allows the bone graft material to smoothly pass through the feeding pipe and the connecting pipe from the connecting valve into the bone graft tube body in sequence, thereby ensuring the continuity and stability of material transportation.

[0013] Preferably, the edge of the outer wall of the piston is tightly slidably fitted with the inner wall of the bone graft tube body, and the outer wall of the push handle is provided with textures;

[0014] Through the above technical solution, the close fit between the piston and the inner wall of the bone graft tube body ensures that when the piston is pushed, the bone graft material can be effectively pushed out without leakage or backflow. The texture on the outer wall of the push handle increases the friction, so that the doctor can hold the push handle more stably during operation.

[0015] Preferably, the outer wall of the bone graft tube body is provided with scale lines;

[0016] Through the above technical solution, the setting of the scale lines provides an intuitive reference for doctors, so that doctors can accurately understand the remaining amount of bone graft material in the bone graft tube body and the pushing depth.

[0017] Preferably, a battery panel is provided on one side of the inner wall of the rear fixing plate, and a button is provided on the other side of the rear fixing plate;

[0018] Through the above technical solution, the battery panel provides power support for the micro LED lamp beads, allowing the lighting device to work independently without being restricted by the power lines of other equipment in the operating room.

[0019] Preferably, the front end of the auger penetrates the connecting pipe to the outside of the connecting pipe and is fixedly connected to the rear end of the rotating disk, and the upper part of the front end of the outer wall of the rotating disk is fixedly connected with a grip rod;

[0020] Through the above technical solution, the connection method between the auger and the rotating disk enables the auger to rotate stably in the connecting tube by rotating the grip. The position and design of the grip conform to the ergonomic principle, and the doctor can easily hold the grip and rotate it during operation, thereby effectively controlling the rotation speed of the auger.

[0021] Preferably, the diameter of the four micro LED lamp beads is 1-3 mm, the light emitting angle is between 60-120 degrees, and the outer walls of the four micro LED lamp beads are provided with an anti-reflective coating;

[0022] Through the above technical solution, micro LED lamp beads with appropriate diameters can ensure the lighting effect without causing excessive impact on the overall structure and operation of the bone grafter. The 60-120 degree light-emitting angle can provide a relatively wide and uniform lighting range to meet the lighting needs of the bone grafting site during surgery. The setting of the anti-reflective coating can effectively reduce the reflection of light in the surgical area, avoid interference with the doctor's vision due to reflection, and enable the doctor to observe the details of the surgical site more clearly.

[0023] (III) Beneficial effects

[0024] The present invention provides an orthopedic bone implant, which has the following beneficial effects:

[0025] 1. The present invention provides an orthopedic bone grafting device, which transmits the material needed for bone grafting through a connecting valve, causing it to fall into a feeding tube. Since the feeding tube and the connecting tube are connected, the material needed for bone grafting enters the connecting tube. The user rotates the handle to drive the rotating disk to rotate, thereby moving the auger, thereby transporting the material needed for bone grafting to the inside of the bone grafting tube body. For some granular, powdered or viscous bone grafting materials (such as some artificial bone materials), blockage is very likely to occur during the transportation process, and the spiral structure of the auger can effectively break up these materials, so that they are evenly distributed in the connecting tube and the bone grafting tube body, keeping the transportation channel unobstructed. At the same time, this transportation method also reduces the contact between the material needed for bone grafting and the air, and can control the amount of the material needed for bone grafting.

[0026] 2. The present invention provides an orthopedic bone grafting device, in which the user turns on micro LED lamp beads by pressing a button. Four micro LED lamp beads are installed at equal distances. These lamp beads usually have good biocompatibility and waterproof performance. Their diameter is 1-3 mm and the light-emitting angle is between 60-120 degrees. This can provide relatively uniform annular lighting. In some deep surgical sites or those with poor lighting conditions, such as spinal surgery or deep bone defect repair, this lighting device can provide clear local lighting, which can reduce operational errors caused by shadows and allow doctors to more accurately see the details of the bone grafting site, such as the boundaries of the bone defect, the location of surrounding blood vessels and nerves, etc., so as to perform bone grafting operations more accurately.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-8 As shown, the embodiments of the present invention provide;

[0039] A bone grafting device for orthopedics, comprising a bone grafting tube body 1, a connecting tube 2 is arranged in the middle of the front end of the outer wall of the bone grafting tube body 1, a feeding tube 3 is arranged at the front end of the upper part of the outer wall of the connecting tube 2, a connecting cover 8 is arranged at the upper end of the feeding tube 3, a connecting valve 9 is connected through the upper end of the connecting cover 8, a piston 7 is arranged inside the bone grafting tube body 1, and a push rod 5 is fixedly connected to the upper end of the piston 7;

[0040] The upper end of the push rod 5 is fixedly connected with a push handle 6, the upper parts of the front and rear outer walls of the bone grafting tube body 1 are fixedly connected with a fixing plate 4, one side of the rear fixing plate 4 is clamped with a clamping cover 13, four micro LED lamp beads 16 are arranged around the lower end of the bone grafting tube body 1, the inner wall of the connecting tube 2 is rotatably connected with a screw dragon 11, and the front end of the connecting tube 2 is provided with a rotating disk 10;

[0041] Some granular, powdery or viscous bone grafting materials are prone to blockage during transportation. The spiral structure of the auger 11 can effectively break up these materials and evenly distribute them in the connecting tube 2 and the bone grafting tube body 1, thereby keeping the transportation channel unobstructed.

[0042] The rear end of the connecting tube 2 is connected to the middle part of the front end of the bone grafting tube main body 1, and the lower end of the feeding tube 3 is connected to the upper part of the front end of the connecting tube 2. This connection method allows the bone grafting material to smoothly pass through the feeding tube 3 and the connecting tube 2 from the connecting valve 9 into the bone grafting tube main body 1 in sequence, ensuring the continuity and stability of material transportation.

[0043] The edge of the outer wall of the piston 7 is tightly slidably fitted with the inner wall of the bone graft tube body 1, and the outer wall of the push handle 6 is provided with texture. The tight fit between the piston 7 and the inner wall of the bone graft tube body 1 ensures that when the piston 7 is pushed, the bone graft material can be effectively pushed out without leakage or backflow. The texture on the outer wall of the push handle 6 increases the friction force, and the doctor can hold the push handle 6 more stably during operation. The outer wall of the bone graft tube body 1 is provided with scale lines 15. The setting of the scale lines 15 provides an intuitive reference for the doctor, so that the doctor can accurately understand the remaining amount of bone graft material in the bone graft tube body 1 and the pushing depth.

[0044] A battery panel 12 is provided on one side of the inner wall of the rear fixing plate 4, and a button 14 is provided on the other side of the rear fixing plate 4. The battery panel 12 provides power support for the micro LED lamp beads, so that the lighting device can work independently and is not restricted by the power lines of other equipment in the operating room. The front end of the auger 11 passes through the connecting tube 2 to the outside of the connecting tube 2 and is fixedly connected to the rear end of the rotating disk 10. The upper part of the front end of the outer wall of the rotating disk 10 is fixedly connected with a grip 17. The connection method between the auger 11 and the rotating disk 10 allows the auger 11 to rotate stably in the connecting tube 2 by rotating the grip 17. The position and design of the grip 17 conform to the principle of ergonomics. The doctor can easily hold the grip 17 and rotate it during operation, thereby effectively controlling the rotation speed of the auger 11.

[0045] The diameter of the four micro LED lamp beads 16 is 1-3 mm, and the luminous angle is between 60-120 degrees. The outer walls of the four micro LED lamp beads 16 are provided with an anti-reflective coating. The micro LED lamp beads with appropriate diameters will not cause excessive impact on the overall structure and operation of the bone grafter while ensuring the lighting effect. The luminous angle of 60-120 degrees can provide a relatively wide and uniform lighting range to meet the lighting requirements of the bone grafting site during surgery. The setting of the anti-reflective coating can effectively reduce the reflection of light in the surgical area, avoid interference with the doctor's vision due to reflection, and enable the doctor to observe the details of the surgical site more clearly.

[0046] Working principle: The doctor first connects the connecting valve 9 with the storage container containing the bone graft material, and then controls the speed of the bone graft material entering the feeding tube 3 from the storage container by adjusting the opening of the connecting valve 9 according to the needs of the operation. The bone graft material flows downward along the feeding tube 3 under the action of gravity. Since the feeding tube 3 is connected with the connecting tube 2, the material smoothly enters the connecting tube 2. The user holds the grip 17 and drives the rotating disk 10 to rotate by rotating the grip 17. The rotation of the rotating disk 10 drives the auger 11 connected thereto to rotate in the connecting tube 2. During the rotation process, the spiral blades of the auger 11 generate a forward thrust and stirring effect on the bone graft material entering the connecting tube 2. On the one hand, the granular, powdery or viscous bone graft material that may be accumulated or agglomerated is broken up and evenly distributed in the connecting tube 2. On the other hand, the bone graft material is pushed forward so that it smoothly passes through the connecting tube 2 and enters the inside of the bone graft tube body 1. In this process, the doctor can adjust the rotation speed of the auger 11 by controlling the rotation speed of the grip 17, thereby controlling the input of the bone graft material. The delivery speed and amount are improved. At the same time, since the spiral structure of the auger 11 can effectively fill the space in the connecting tube 2, the contact area between the bone graft material and the air is reduced, thereby reducing the risk of material contamination. When the button 14 is pressed, the circuit is connected, and the battery panel 12 provides power for the micro LED lamp beads. The current output by the battery panel 12 is transmitted to the LED lamp beads at the lower end of the bone graft tube body 1 through the wire. Since the LED lamp beads are installed equidistantly around the lower end of the bone graft tube body 1, the light they emit forms an annular lighting area. In some deeper or poorly illuminated surgical sites, such as spinal surgery or deep bone defect repair, this annular lighting area can provide doctors with clear local lighting, illuminating the details of the bone graft site, including the boundaries of the bone defect, the location of surrounding blood vessels and nerves, etc. Doctors can perform bone grafting operations more accurately and reduce operational errors caused by shadows. At the same time, the LED lamp beads have good biocompatibility and waterproof properties, can work safely and reliably in a surgical environment, and will not cause additional risks to patients.
