Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an electric push injection structure for bone wax. Background Art

[0002] Bone bleeding during open surgery is usually blocked and stopped by applying bone wax. Bone wax can be used to stop bleeding from bone marrow capillaries caused by bone fractures, drilling or fragmentation at different ages, locations and for different reasons.

[0003] Bone wax is commonly applied manually. However, during minimally invasive procedures such as unilateral dual-port arthroscopic spinal endoscopic surgery (UBE) or transforaminal endoscopic spinal surgery, the narrow working channel prevents traditional delivery instruments and manual intervention from reaching the affected bone. Currently, a nerve dissector is commonly used to apply bone wax to the bleeding bone wound surface, but this process can cause the wax to fall off.

[0004] Many bone wax injection system design methods have been proposed in the prior art. The main solution is manual injection by the operator. However, this solution requires high operating skills of the operator and it is difficult to accurately control the amount of wax output. Excessive wax output will increase the risk of bone wax falling off, while too little wax output will not achieve the expected surgical effect. Summary of the Invention

In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0040] The electric push injection structure for bone wax provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0041] like Figures 1 to 3 As shown, an embodiment of the present application provides an electric push injection structure for bone wax, including a mounting portion 100, a delivery tube fixedly arranged on the mounting portion 100, a push rod 400 slidably arranged in the delivery tube, and an electric drive unit fixedly arranged on the mounting portion 100 and used to drive the push rod 400 to slide relative to the delivery tube.

[0042] A transition channel for accommodating bone wax is provided in the conveying tube, and a wax outlet communicating with the outside is provided at one end of the transition channel away from the mounting portion 100 .

[0043] The push rod 400 is slidably connected to the transition channel, and when sliding relative to the delivery tube, it can squeeze the bone wax in the transition channel to the outside of the delivery tube through the wax outlet.

[0044] In an embodiment of the present application, the above-mentioned electric pushing structure for bone wax is adopted, and the bone wax in the delivery tube is pushed by an electric drive unit. Not only is the pushing efficiency high, but the wax output can also be controlled more accurately to ensure the bone wax coating effect. At the same time, a rod-shaped structure is used to deliver bone wax, which is convenient for small-scale application under laparoscopic surgery, avoiding the falling of bone wax during the operation, and improving the overall reliability of bone wax delivery.

[0045] In a preferred embodiment, as Figures 1 to 3 As shown, the electric drive unit includes a power unit and a transmission assembly connected to the power unit.

[0046] It is understandable that the power unit is mainly used to supply energy to the transmission assembly. Under the energy supply of the power unit, the transmission assembly can drive the push rod 400 to slide relative to the conveying tube, thereby realizing the push injection of bone wax in the conveying tube.

[0047] In a preferred embodiment, as Figures 1 to 3 As shown, the power unit includes a driving motor 210 fixedly disposed on the mounting portion 100 and a control unit 220 coupled to the driving motor 210 .

[0048] Among them, the power input end of the transmission component is connected to the power output end of the drive motor 210, and the control unit 220 is used to control the working state of the drive motor 210, thereby adjusting the sliding direction, sliding speed and other parameters of the push rod 400 in the conveying pipe.

[0049] It is understandable that the control unit 220 can be set as a switch component fixedly installed on the mounting portion 100, or can be set as a remote control module communicated with the electric push injection structure. As long as it can achieve control of the working state of the drive motor 210, it will not be elaborated here.

[0050] In a preferred embodiment, as Figures 1 to 3 As shown, the power unit further includes a battery unit 230 connected to the drive motor 210 and the control unit 220 .

[0051] It is understandable that the battery unit 230 is mainly used to power the drive motor 210 and the control unit 220 . The battery unit 230 can be set on the mounting portion 100 or as an external power source outside the mounting portion 100 .

[0052] In a preferred embodiment, as Figure 1 As shown, the transmission assembly includes a screw rod 320 rotatably connected to the mounting portion 100 , and a screw block 330 fixedly disposed on one end of the push rod 400 close to the mounting portion 100 and threadedly connected to the screw rod 320 .

[0053] Among them, the end of the screw 320 away from the conveying pipe is connected to the power output end of the drive motor 210 through the coupling 310. The screw 320 is parallel to the central axis of the conveying pipe and can drive the push rod 400 to slide in the conveying pipe when rotating.

[0054] In a preferred embodiment, as Figure 1 As shown, the transmission assembly further includes a guide rail 340 fixedly disposed on the mounting portion 100 and slidably connected to the screw block 330 , and the length direction of the guide rail 340 is parallel to the axial direction of the screw rod 320 .

[0055] It is understandable that when the screw rod 320 rotates to drive the screw block 330 to move, the guide rail 340 guides the screw block 330, thereby improving the movement stability of the push rod 400.

[0056] In a preferred embodiment, as Figure 2 、 Figure 3 As shown, the transmission assembly includes a guide seat 620 fixedly set on the mounting portion 100, a slider 630 linearly slidingly set on the guide seat 620 and fixedly connected to the push rod 400, and also includes a connecting rod assembly connected to the slider 630 and the power unit.

[0057] The connecting rod assembly can drive the slider 630 to slide linearly relative to the guide seat 620 under the drive of the power unit, and the linear sliding direction of the slider 630 is parallel to the axial direction of the push rod 400.

[0058] It is understandable that when the connecting rod assembly drives the slider 630 to slide relative to the guide seat 620, it can simultaneously drive the pushing rod 400 to slide relative to the delivery tube, thereby achieving the push injection of bone wax in the delivery tube.

[0059] In an embodiment of the present application, the above-mentioned electric push-in structure for bone wax is adopted, and the power unit drives the connecting rod assembly to realize the sliding of the slider 630 relative to the guide seat 620, thereby realizing the pushing of the bone wax in the conveying tube by the pushing rod 400. Compared with the threaded screw drive structure, the connecting rod assembly has a faster response speed, a smaller size and a longer driving control stroke of the pushing rod, which further improves the bone wax pushing efficiency.

[0060] In a preferred embodiment, as Figure 2 、 Figure 3 As shown, the connecting rod assembly includes a driven rod 640 and an active rod 650 . The first end of the driven rod 640 is hinged to the first end of the active rod 650 , and the second end is hinged to the slider 630 . The second end of the active rod 650 is rotatably connected to the mounting portion 100 .

[0061] The power unit can drive the second end of the active rod 650 to rotate relative to the mounting portion 100 .

[0062] It can be understood that when the power unit drives the active rod 650 to rotate relative to the mounting portion 100, the driven rod 640 swings synchronously driven by the active rod 650. Since the first end of the driven rod 640 is hinged to the slider 630, when the angle between the driven rod 640 and the active rod 650 changes, the slider 630 can be pushed to slide linearly relative to the guide seat 620, thereby realizing the push rod 400 to push the bone wax into the conveying tube.

[0063] In a preferred embodiment, as Figure 2 、 Figure 3 As shown, a driven bevel gear 670 is fixedly provided at the second end of the active rod 650 , and an active bevel gear 660 meshing with the driven bevel gear 670 is fixedly provided at the power output end of the drive motor 210 .

[0064] The driven bevel gear 670 is coaxial with the rotation axis of the second end of the active rod 650 .

[0065] It is understandable that when the driving motor 210 drives the active bevel gear 660 to rotate, the active bevel gear 660 can drive the driven bevel gear 670 to rotate, thereby achieving the swing of the second end of the active rod 650 relative to the mounting portion 100 .

[0066] In a preferred embodiment, as Figure 2 、 Figure 3 As shown, a guide groove 610 is provided on the guide seat 620 , and a slider 630 is slidably disposed in the guide groove 610 .

[0067] In a preferred embodiment, as Figure 1 As shown, the conveying pipe includes a sleeve 510 fixedly arranged on the mounting portion 100 and a joint 520 detachably fixedly arranged at an end of the sleeve 510 away from the mounting portion 100 .

[0068] The connector 520 is used for pre-filling bone wax, and includes a docking portion detachably connected to the sleeve 510 and an applicator head fixedly arranged at one end of the docking portion away from the sleeve 510 .

[0069] In an embodiment of the present application, the above-mentioned electric push-in structure for bone wax is adopted. Since the connector 520 and the sleeve 510 are detachable, bone wax can be pre-filled in the connector 520. The operator can replace the connector 520 multiple times when performing work, which solves the problem that the inner cavity of the traditional conveyor is difficult to clean and the cleaning is not thorough, and there is no need to heat the bone wax additionally.

[0070] In a preferred embodiment, as Figure 2 、 Figure 3 As shown, the delivery pipe is configured as a wax storage pipe 530 fixedly mounted on the mounting portion 100 .

[0071] It is understandable that when the above structure is adopted, the bone wax needs to be heated and melted and then sucked into the transition channel in the wax storage tube 530.

[0072] In a preferred embodiment, as Figure 2 、 Figure 3 As shown, a bracket 110 is fixed on the mounting portion 100 , and the driving motor 210 is fixed on the bracket 110 .

[0074] In a preferred embodiment, the mounting portion 100 is made of PVC or ABS material, and is connected to the conveying pipe by bonding, threading, welding, or the like.

[0075] In a preferred embodiment, the conveying pipe and / or the pushing rod 400 are made of stainless steel 304 / 316 or the like.

[0076] It is understandable that the driving form of the push rod 400 is not limited to the above embodiment. For example, a cylinder or electric push rod structure can also be set on the mounting part 100. As long as the sliding control of the push rod 400 in the conveying pipe can be achieved, it will not be elaborated here.
