Description

Technical Field

[0001] This application relates to the field of surgical instrument technology, and in particular to a device for applying bone wax under spinal endoscopy. Background Technology

[0002] Occasionally, patients experience bleeding in the bone area during minimally invasive spinal surgery. Currently, medical staff often use the following method to stop the bleeding: First, they use medical cotton to perform initial hemostasis at the bleeding site (at this point, the surgery is stopped); when the amount of bleeding in the endoscopic field of vision decreases (i.e., a large area of ​​blood has been wiped away with medical cotton), the medical staff use their hands to shape the bone wax (bone wax needs to be shaped and transferred, and it cannot be inserted immediately based on the previously obtained information on the amount of bleeding when the field of vision disappears), and then insert it into the patient's site through the endoscope sheath channel for secondary hemostasis.

[0003] Considering that bone wax hemostasis cannot be performed if the endoscopic view is blurred, medical cotton is used for initial hemostasis beforehand. However, even if the medical cotton reduces the patient's bleeding to the preset amount and provides medical staff with a clear view, blood will still stick to the endoscope again during the plasticization and transfer of the bone wax, causing the endoscopic view to become blurred again.

[0004] Therefore, there is an urgent need for a spinal endoscopy bone wax application device to address, to some extent, the technical problems existing in the current technology. Utility Model Content

[0026] The transmission rod is disposed inside the connecting plate, and one end of it is rotatably connected to the pull rod along the first direction, and the other end is rotatably connected to the guide rod.

[0027] The end of the pull rod opposite to the transmission rod is fixedly connected to the rotating disk; the guide rod is connected to the base, and the transmission rod is rotatably connected to the second rotating shaft.

[0028] In the above technical solution, further, the connecting plate is provided with a mounting groove extending along the first direction;

Detailed Implementation

[0053] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0054] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0055] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0056] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0057] This application addresses, to some extent, the inconvenience and operational difficulty of existing endoscopic methods for hemostasis of bone. The following section combines... Figures 1-12 This application provides a detailed description of a device for remembering endoscopic bone wax application.

[0058] Combination Figure 1 As shown, the spinal endoscopy bone wax application device includes an application component 1, a transmission component, and a gripping component 3.

[0059] Specifically, the application component 1 includes a fixing part 4 and an application part 5; the application part 5 is connected to the holding component 3 via a transmission component, and the holding component 3 has an elastic part 6.

[0060] In actual use, the fixing part 4 and the application part 5 are located on both sides of the spine. The application part 5 corresponds to the bleeding position and is used to place bone wax. When the elastic part 6 is compressed, the transmission component can move the application part 5 toward the fixing part 4 and close it at the bleeding position of the spine so that the bone wax can be applied to the spine. When the elastic part 6 is reset, the transmission component can move the application part 5 away from the spine.

[0061] In summary, this application utilizes the compression and repositioning of the elastic part 6 to drive the application part 5 to close at or away from the bleeding site. Compared with the complex operation of wiping with medical sterile cotton and then using bone wax for hemostasis in the prior art, this application has a simple structure and is easy to operate.

[0062] In this embodiment, further, combined with Figure 1 As shown, the grip assembly 3 includes a handle and a spring 8 that can serve as an elastic part 6.

[0063] Specifically, there are two handles, namely a first handle 7 and a second handle 9, and a spring 8 is provided between the first handle 7 and the second handle 9.

[0064] In actual use, when the first handle 7 and the second handle 9 are held and moved in opposite directions (i.e., when the first handle 7 and the second handle 9 are squeezed), the spring 8 will be compressed. At this time, the second handle 9 will pull the transmission component in the opposite direction. Figure 1 The right-side movement of the transmission component causes the application part 5 to move towards the fixing part 4 and close against the spine, thereby applying bone wax to the bleeding site. After applying the bone wax to the bleeding site, releasing the handle causes the spring 8 to return to its original position, at which point the transmission component will move towards the fixed part 4. Figure 1 The movement to the left side of the body causes the smeared part 5 to move away from the spine.

[0065] In this embodiment, further, combined with Figure 1 As shown, the application component 1 also includes a connecting plate 10.

[0066] Specifically, the connecting plate 10 extends along a first direction 11, where the first direction 11 is in Figure 1 As shown in the diagram, this refers to the left-right direction. One end of the connecting plate 10 is fixedly connected to the fixing part 4, and the other end of the connecting plate 10 is fixedly connected to the first handle 7 and rotatably connected to the second handle 9.

[0067] Specifically, the fixing part 4 has a recessed fixing cavity 12 on the side facing the application part 5, and the application part 5 has an application protrusion 13 that is adapted to the fixing cavity 12 protruding from the fixing part 4.

[0068] The fixing part 4 can prevent the bone wax from spreading to the surrounding area; in addition, the shape and size of the fixing cavity 12 and the coating protrusion 13 are not specifically limited, as long as they are compatible.

[0069] In this embodiment, further, combined with Figure 3 and Figure 4 As shown, the fixing part 4 includes a fixing housing 14, which is preferably cylindrical. The fixing housing 14 has a fixing cavity 12 on the side facing the application part 5, which is preferably hemispherical.

[0070] Furthermore, combined Figure 3 and Figure 4 As shown, the coating part 5 also includes a base 16; the coating protrusion 13 is disposed on the side of the base 16 facing the fixing part 4; the coating protrusion 13 is a hemispherical shape adapted to the hemispherical fixing cavity 12.

[0071] Furthermore, the application protrusion 13 is made of rubber, which has a certain degree of flexibility so it will not cause secondary damage to the bleeding site; in addition, the rubber material has a certain degree of elasticity, and when the application protrusion 13 is pressed onto the bleeding site, the elasticity allows the bone wax to be tightly applied to the bleeding site.

[0072] In this embodiment, further, combined with Figures 5-7 As shown, the transmission assembly includes a rotating disk 17, a pull rod 18, a transmission rod 19, and a guide rod 20.

[0073] Specifically, the rotating disk 17 is rotatably mounted on the end of the connecting plate 10 away from the coating part 5 via the first rotating shaft 21, and the second handle 9 is fixedly connected to the rotating disk 17.

[0074] Specifically, the connecting plate 10 has a lug 22 on the side facing the sidewall of the coating part 5 and close to the coating part 5, and a second rotating shaft 23 is provided on the lug 22.

[0075] Specifically, the transmission rod 19 is disposed inside the connecting plate 10, and one end of it is rotatably connected to the pull rod 18 along the first direction 11, and the other end is rotatably connected to the guide rod;

[0076] Specifically, the end of the pull rod 18 away from the transmission rod 19 is fixedly connected to the rotating disk 17; the guide rod is connected to the base 16, and the transmission rod 19 is rotatably connected to the second rotating shaft 23.

[0077] Preferably, the guide rod includes a first segment 26, a second segment 27, and a third segment 28 connected in sequence; the first segment 26 is connected to the transmission rod 19, the third segment 28 is connected to the base 16, the first segment 26 and the second segment 27 are at an angle of 135°, and the second segment 27 and the third segment 28 are at an angle of 175°.

[0078] In summary, during actual use, when the first handle 7 and the second handle 9 are squeezed, the spring 8 is compressed, and the second handle 9 rotates clockwise. At this time, the rotating disk 17 also rotates clockwise. When the rotating disk 17 rotates clockwise, it drives the pull rod 18 to rotate clockwise. Since the transmission rod 19 and the pull rod 18 are rotatably connected via the first rotating shaft 21, the transmission rod 19 will then move towards... Figure 1 The movement is to the right; when the transmission rod 19 moves to the right, since the transmission rod 19 and the first section 26 of the guide rod are rotatably connected, and since the guide rod is rotatably connected to the lug 22 through the second rotating shaft 23, the application protrusion 13 will be driven to move toward the fixed cavity 12. When the spring 8 returns to its original position, the movement process is reversed, and the application protrusion 13 will move out of the fixed cavity 12.

[0079] In this embodiment, further, combined with Figure 6 As shown, the connecting plate 10 has a mounting groove 24 extending along the first direction 11; the transmission rod 19 is disposed in the mounting groove 24 and can move within the mounting groove 24 along the first direction 11.

[0080] Furthermore, the mounting groove 24 has sliding grooves extending along the first direction 11 on opposite side walls; the transmission rod 19 has a slider that can slide in the sliding groove and protrudes towards the sliding groove at a position opposite to the sliding groove.

[0081] In summary, by using the slider to move within the groove, the transmission rod 19 is assisted in moving within the mounting groove 24, ensuring that the coating protrusion 13 can smoothly close into or move out of the fixed cavity 12, and preventing jamming when the coating protrusion 13 closes into or moves out of the fixed cavity 12.

[0082] In this embodiment, further, combined with Figure 1 As shown, the grip assembly 3 also includes a grip ring 25; the grip ring 25 is respectively disposed on the opposite side of the two handles; the grip ring 25 surrounds a grip space for the hand to reach into.

[0083] In summary, the grip component 3 is similar to the handle structure of scissors. When the hand is inserted into the grip space, it is convenient to grip the first handle 7 and the second handle 9 with force.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
