Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a bone wax push injection system and a push injection method. Background Art

[0002] Bone bleeding during open surgery is usually blocked and hemostatically blocked with 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] The common method of applying bone wax is manual application, but when it comes to minimally invasive surgery, such as unilateral dual-channel arthroscopic spinal endoscopic surgery (UBE) or transforaminal endoscopic surgery, due to the narrow aperture of the working channel, traditional delivery instruments and human hands cannot reach the bone affected area. Now it is common to use a nerve stripper to dip bone wax and insert it into the bleeding bone wound surface, but the bone wax may fall off during the insertion process.

[0004] At the same time, many bone wax push injection system design methods have been proposed in the prior art. The main scheme is to heat and melt the wax before injecting it, then suck it into the push injection system, and finally push it to the use site. However, since bone wax is composed of more than two components, the melting points of these components are different, resulting in uneven mixing of the components of the bone wax after heating and melting, which ultimately leads to poor sealing performance and poor hemostasis when using such push injection smearing systems to stop bleeding.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0050] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0051] The bone wax injection system and injection method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0052] Example 1

[0053] like Figures 1 to 8 As shown, an embodiment of the present application provides a bone wax injection system, including an injector, a connector 200 detachably disposed on the injector and having bone wax 300 pre-installed therein, or further including a heating unit for heating the bone wax 300 in the connector 200 .

[0054] A transition channel for accommodating the bone wax 300 is provided in the connector 200, and a coating head is provided at one end away from the injector, and a wax outlet communicated with the transition channel is provided on the coating head.

[0055] When the connector 200 and the injector are connected, the injector can squeeze the bone wax 300 preset in the transition channel to the outside of the connector 200 through the wax outlet.

[0056] In an embodiment of the present application, the above-mentioned bone wax injection system is adopted, the connector 200 is detachably connected to the injector, and the bone wax 300 is preset in the connector 200. During the operation, the connector 200 can be directly replaced on the injector, thereby ensuring the continuity of hemostasis. Since there is no need to replace the entire injector, not only the working efficiency of the bone wax injection system is improved, but also the treatment cost of the patient is greatly reduced.

[0057] In a preferred embodiment, Figure 1 , Figure 2 As shown, a coating surface is provided at one end of the coating head of the connector 200 away from the injector, and an angle between the central axis of the transition channel and the coating surface is set to 0° to 90°.

[0058] In a preferred embodiment, the bone wax 300 is composed of at least two degradable polymer materials, one of which has a melting point below 30°C, and the remaining materials have an overall melting point below 50°C after being mixed.

[0059] It is understandable that the heating method of polymer absorbable bone wax is different from the traditional heating method for complete melting and injection. After being heated to a temperature slightly higher than the human body temperature, the low-melting-point component material first melts slightly on the inner wall of the transition channel to act as a lubricant. The polymer absorbable bone wax is injected through two mechanisms: lubrication and softening, thereby greatly reducing the injection force.

[0060] In a preferred embodiment, Figure 1 , Figure 2 , Figure 5 As shown, the injector includes a mounting portion 110 and a push rod 120 disposed on the mounting portion 110 and capable of axially moving relative to the mounting portion 110 , and a connector 200 is detachably disposed on the mounting portion 110 .

[0061] When the connector 200 and the injector are connected, the push rod 120 can squeeze the bone wax 300 preset in the transition channel to the outside of the connector 200 through the wax outlet when it moves relative to the mounting portion 110 .

[0062] In a preferred embodiment, the connector 200 is detachably connected to the mounting portion 110 via threads or snaps.

[0063] In a preferred embodiment, the injector further includes a sleeve 130 fixedly mounted on the mounting portion 110 and coaxial with the push rod 120 , the push rod 120 is slidably mounted in the sleeve 130 , and the connector 200 is detachably mounted at one end of the sleeve 130 away from the mounting portion 110 .

[0064] When the connector 200 and the injector are connected, the push rod 120 can squeeze the bone wax 300 preset in the transition channel to the outside of the connector 200 through the wax outlet when the push rod 120 moves relative to the mounting portion 110 and the push rod 120 .

[0065] In an embodiment of the present application, the above-mentioned bone wax injection system is adopted, and the injector adopts a rod-shaped structure to transport bone wax, which is convenient for small-area application under laparoscopic surgery, avoids the bone wax from falling during the operation, and improves the overall reliability of bone wax delivery.

[0066] In a preferred embodiment, the connector 200 is detachably connected to the end of the sleeve 130 away from the mounting portion 110 via threads or snaps.

[0067] It is understandable that the detachable connection method between the connector 200 and the syringe is not limited to the above-mentioned embodiment. For example, a detachable connection structure such as a snap connection can also be adopted, as long as the connector 200 can be quickly disassembled from the syringe, which will not be elaborated here.

[0068] In a preferred embodiment, the push rod 120 is slidably connected or threadedly connected to the mounting portion 110 .

[0069] Among them, when the push rod 120 is set to be slidably connected with the mounting part 110, when the push rod 120 is pushed to slide relative to the mounting part 110, the bone wax 300 pre-installed in the joint part 200 can be pushed out to the application position; when the push rod 120 is set to be threadedly connected with the mounting part 110, rotating the push rod 120 can make it move axially along the mounting part 110, thereby pushing the bone wax 300 pre-installed in the joint part 200 to the application position.

[0070] It is understandable that when the push rod 120 is configured to be threadedly connected to the mounting portion 110, precise control of the axial movement distance of the push rod 120 can be achieved by rotating the push rod 120, thereby achieving quantitative discharge of the preset bone wax 300 in the joint 200 and improving the accuracy of the injection of the bone wax 300.

[0071] In a preferred embodiment, the bone wax 300 is loaded into the connector 200 by casting, filling, die-casting, filling, and injection molding.

[0072] In a preferred embodiment, the sleeve 130 and / or the connector 200 are made of medical metal with excellent thermal conductivity.

[0073] Example 2

[0074] like Figure 3 , Figure 4 As shown, an embodiment of the present application provides a bone wax injection system, wherein a heating unit includes a heating box 400 and a first display unit 410 and a control module arranged on the heating box 400 .

[0075] The heating box 400 includes a base 401 and a cover plate 403 hingedly disposed on the base 401 . At least one heating groove 402 matching the connector 200 is disposed on an end surface of the base 401 close to the cover plate 403 .

[0076] Among them, the connector 200 can be embedded in the heating groove 402, and the connector 200 in the heating groove 402 can be heated when the base 401 and the cover plate 403 are in a closed state. The first display unit 410 can display the heating temperature of the connector 200 by the heating box 400, and the control module is used to adjust the heating temperature of the connector 200 by the heating box 400.

[0077] It is understandable that the connector 200 can be placed in the heating box 400 for heating alone, or it can be installed on the injector and placed in the heating box 400 together with the injector for heating. As long as the heating effect of the pre-installed bone wax 300 in the connector 200 can be guaranteed, it will not be elaborated here.

[0078] In an embodiment of the present application, the above-mentioned bone wax injection system is adopted, and the heating of the joint component 200 can be achieved through the heating box 400. At the same time, the heating temperature of the joint component 200 can be accurately controlled through the control module, so that the bone wax 300 preset inside it can be accurately heated to a softened state without melting, which makes it easy for the injector to push out the bone wax 300 in the joint component 200, so that its components can be evenly and easily pushed to the hemostasis site.

[0079] It is understandable that the configuration of the heating box 400 is not limited to the above-mentioned one, as long as it can achieve heating of the connector 200, which will not be elaborated here.

[0080] In a preferred embodiment, the control module at least includes an on / off key, a temperature plus key, and a temperature minus key.

[0081] Example 3

[0082] like Figures 5 to 8 As shown, an embodiment of the present application provides a bone wax injection system, wherein the heating unit is specifically configured as an integrated heating module 420 that is fixedly mounted on the mounting portion 110 and can be coupled to the connector 200 .

[0083] The integrated heating module 420 includes a mounting base 421 fixedly arranged on the mounting portion 110, on which an energy storage unit 422, an input end 423, an output end 424, a control module 425, and a second display unit 426 are fixedly arranged. The input end 423 is used to supply energy to the energy storage unit 422, and the output end 424 is used to output the electric energy of the energy storage unit 422. The second display unit 426 can display the heating temperature of the docking joint component 200, and the control module 425 is used to adjust the heating temperature of the docking joint component 200.

[0084] A plurality of slave contacts 220 are fixedly arranged in a circular array on the end surface of the connector 200 close to the injector about the central axis of the transition channel. A heat conducting wire 210 is fixedly arranged on the slave contact 220 . The heat conducting wire 210 extends along the length direction of the connector 200 away from the injector.

[0085] When the connector 200 and the injector are connected, the output end 424 is coupled to the plurality of slave contacts 220 , respectively, and the bone wax 300 preset inside the connector 200 can be heated through the heat conducting wire 210 .

[0086] In an embodiment of the present application, the above-mentioned bone wax injection system is adopted, and the heating unit is directly arranged on the injector, which is convenient to operate and easy to use. After installing or replacing the connecting piece 200 on the injector, the heating unit on the injector can directly heat the pre-installed bone wax 300 inside the connecting piece 200, which improves the heating efficiency of the bone wax 300 on the one hand, and shortens the interval time between the heating of the bone wax 300 and its use in surgery on the other hand, so that the bone wax 300 can be softened and promptly used for injection and application, thereby improving its use effect.

[0087] In a preferred embodiment, Figure 7 As shown, a plurality of main contacts 428 matching the positions of the plurality of slave contacts 220 are provided on the end face of the sleeve 130 away from the mounting portion 110, and a fixed resistance wire 427 is fixed on the main contact 428. The resistance wire 427 extends along the length direction of the sleeve 130 toward the side away from the connector 200 and is electrically connected to the output terminal 424 (the electrical connection specifically means that the current output by the output terminal 424 can be transmitted to the resistance wire 427).

[0088] When the connector 200 and the injector are in a connected state, the plurality of main contacts 428 can respectively abut against the slave contacts 220 at corresponding positions.

[0089] It is understandable that when the connector 200 and the injector are not properly installed, the main contact 428 and the slave contact 220 are not aligned, and the heating unit cannot start heating at this time, thereby avoiding the connector 200 from falling off due to improper installation.

[0090] In a preferred embodiment, the sleeve 130 is composed of a multi-layer structure in the radial direction, wherein one layer is configured as a heat-conducting layer, and the resistance wire 427 is disposed in the heat-conducting layer of the sleeve 130 .

[0091] In a preferred embodiment, Figure 7 As shown, a temperature sensing unit 429 for monitoring the temperature of the connector 200 is disposed at one end of the sleeve 130 away from the mounting portion 110 .

[0092] It is understandable that when the connector 200 and the injector are connected, the temperature sensing unit 429 can visualize the temperature of the connector 200 through the second display unit 426, thereby facilitating the operator to accurately control the temperature of the heating component.

[0093] In a preferred embodiment, the connector 200 can be detachably mounted on the mounting portion 110, and a plurality of main contacts matching the positions of the plurality of slave contacts 220 are provided on an end face of the mounting portion 110 close to the connector 200, and a fixed resistance wire is fixed on the main contacts, which extends along the length direction of the mounting portion 110 away from the connector 200 and is electrically connected to the output terminal 424 (the electrical connection specifically means that the current output by the output terminal 424 can be conducted to the resistance wire).

[0094] When the connector 200 and the injector are in a connected state, the plurality of main contacts 428 can respectively abut against the slave contacts 220 at corresponding positions.

[0095] Example 4

[0096] The present application embodiment provides a bone wax push injection method, which is applicable to the bone wax push injection system in the above embodiments 1 to 3, including:

[0097] Step S1, presetting heating temperature parameters and heating time parameters on the heating unit;

[0098] Step S2: When the pusher and the connector 200 are connected, the heating unit heats the connector 200 based on preset heating temperature parameters and heating time parameters.

[0099] In an embodiment of the present application, the above-mentioned bone wax injection method is adopted, and precise temperature control of the bone wax 300 preset in the joint component 200 is achieved by presetting the heating temperature parameters and the heating time parameters, so that the bone wax 300 preset in the joint component 200 is heated to a softened state without melting, thereby solving the problems of uneven mixing of components of the bone wax 300 after melting and cooling, low hemostasis efficiency, and poor sealing performance.

[0100] In a preferred embodiment, in step S1, the heating temperature parameter is set to 38-41° C., and the heating time parameter is set to 20 s.

[0101] It is understandable that under different heating temperature parameter and heating time parameter settings, the bone wax 300 in the joint 200 will present different structural states, and when the structural states of the bone wax 300 are different (softened or melted), the force of the pusher to push it out of the joint 200 is also different. Therefore, before step S1, it is necessary to experimentally obtain the correlation between the heating temperature parameter, the heating time parameter, and the push force. The specific correlation between the heating temperature parameter, the heating time parameter, and the push force is shown in the following table:

[0102]

[0103] In actual use, a pushing force of the injector less than 20N is suitable for pushing, and less than 15N is the optimal pushing force.

[0104] The traditional push injection system requires heating the bone wax for 5 minutes to completely melt it, and then keeping it warm to wait for the bone wax to solidify, which takes a long time and affects the progress of the operation.

[0105] In an embodiment of the present application, the above-mentioned bone wax injection method is adopted to achieve numerical optimization in three dimensions of heating temperature, heating time and injection force of the injector while ensuring that the structural state of the bone wax 300 remains unchanged after heating. That is, the heating time is shortened under the optimal injection force, thereby greatly improving the injection efficiency.

[0106] In a preferred embodiment, in step S2, it also includes:

[0107] When the heating unit reaches the preset heating temperature parameters and heating time parameters, a warning signal is output.

[0108] It is understandable that the warning signal can be visually output by the first display unit 410 or the second display unit 426 on the heating unit.

[0109] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0110] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
