Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a coagulator. Background Technology

[0002] Bone wax, as a key material for controlling bone bleeding during surgery, plays an irreplaceable role in orthopedics, neurosurgery, and thoracic surgery. Its basic principle is to achieve hemostasis by physically sealing capillary leakage from the bone surface. Traditional bone wax is mainly composed of a mixture of beeswax and petrolatum, and its rapid hemostasis and ease of use make it widely used.

[0003] Specialized bone wax coagulators allow for the application of bone wax to the wound in a more precise and controlled manner. Current bone wax coagulators use a fixed nozzle design, which is not well-suited to the complex surgical environment.

[0004] Current nozzles cannot achieve comprehensive coverage from multiple angles, requiring users to repeatedly adjust instrument positions or apply the coating multiple times, significantly slowing down the surgical process. Furthermore, fixed nozzles perform poorly in traversing tissue fluid environments. Surgical wounds typically contain varying levels of tissue fluid and blood, creating a complex fluid environment that significantly interferes with the adhesion of bone wax. Bone wax sprayed from fixed nozzles experiences hydrodynamic resistance and dilution effects as it traverses fluids, causing the bone wax material to change its properties or partially leak away before reaching the bone surface. Existing fixed nozzles lack adaptive adjustment mechanisms for fluid environments, failing to dynamically adjust spray parameters based on real-time conditions, resulting in insufficient adhesion between the bone wax and the bone surface, easily leading to postoperative detachment. Because the nozzle angle is not adjustable, a single operation can only cover a small area of ​​the wound. For larger areas of bone surface bleeding, users must repeat the operation multiple times, which not only prolongs surgical time but also increases the risk of uneven bone wax application. Summary of the Invention

[0005] The purpose of this invention is to provide a coagulator for forming a multi-angle comprehensive coverage of the wound, avoiding the need for the user to repeatedly adjust the instrument position or apply multiple coats, thus improving operational efficiency. At the same time, it eliminates liquid interference and uses an impact spray effect to allow the reagent to pass smoothly through the liquid and quickly adhere to the wound surface, effectively ensuring the adhesion strength between the reagent and the wound surface, improving the efficiency and success rate of reagent adhesion to the wound surface, increasing surgical efficiency, and reducing surgical risks.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A blood clotting device, comprising:

[0008] The first module includes a container, one end of which has a working end. The container is used to contain reagents, and the working end is used to receive the reagents flowing through the container and discharge them to the bone wound. The working end includes a nozzle and a connector. The container is provided with a squeezing component for squeezing the reagents.

[0009] The second module is detachably connected to the first module. The second module is equipped with a drive component, which is driven by the connector to drive the connector to reciprocate so that the nozzle swings. The drive component is also driven by the extruder and impacts the extruder to increase the spray speed of the reagent and discharge it from the nozzle.

[0010] As an alternative to a coagulation device, the first module includes a housing, the container is located inside the housing, and the working end is extendable within the housing. When the working end is inside the housing, the extension direction of the working end is consistent with the extension direction of the housing; when the working end extends out of the housing, the extension direction of the working end forms a preset bending angle with the extension direction of the housing.

[0011] As an alternative to a coagulation device, the specific angle value of the preset bending angle is determined by the length of the working end extending out of the housing.

[0012] As an alternative to a coagulation device, the drive assembly includes a drive member and a camshaft and a lever that are pulverizedly connected to the drive member. The camshaft has a circumferentially provided limiting groove, and the lever is partially slidably connected to the limiting groove. The camshaft rotates to cause the lever to reciprocate axially, and the lever is pulverizedly connected to the connecting member.

[0013] As an alternative to the coagulation device, the container is provided with two elastic buttons, the two connecting parts are arranged side by side, one end of the two connecting parts is connected to both ends of the nozzle, the other end of the two connecting parts is connected to the two elastic buttons, and the lever is kinetically connected to one of the elastic buttons.

[0014] As an alternative to a coagulation device, the resilient button includes a button element and a first resilient element sleeved on the button element. When the lever presses the button element, it can compress the first resilient element. When the lever releases the button element, the first resilient element causes the button element to reset.

[0015] As an alternative to a coagulation device, the container includes a heating tube and a first sleeve fitted over the heating tube, the first sleeve containing a flowable reagent, and the heating tube being used to heat the reagent.

[0016] As an alternative to a coagulation device, the first cannula is covered with a second cannula.

[0017] As an alternative to the coagulation device, the end of the container away from the working end forms a connecting end, the connecting end including a fixing frame and a heating cylinder, the heating cylinder containing reagents, and the extruder disposed inside the heating cylinder to extrude the reagents inside the heating cylinder into the first sleeve.

[0018] As an alternative to a coagulator, the drive assembly includes a camshaft, an elastic assembly, and an impact block. The camshaft is rotatably connected to the impact block. The camshaft rotates to compress the elastic assembly to store energy. After being compressed to a preset position length, the camshaft releases the energy and drives the impact block axially. The impact block is used to impact the extruder.

[0019] As an alternative to a coagulator, the elastic assembly includes a ratchet, a second elastic element, and a nut. The two ends of the second elastic element are respectively connected to the ratchet and the nut. The nut is threadedly connected to the camshaft. The ratchet is located inside the impact block. The impact block cooperates with the ratchet to allow the second elastic element to store and release energy.

[0020] Beneficial effects:

[0021] In the solution provided by this invention, the first module and the second module are connected in a detachable manner, which facilitates quick connection and disassembly by the user. Furthermore, the drive assembly uses a push-pull connector to pull the nozzle to oscillate relative to the stator within a first angular range. Simultaneously, the push-pull action of the connector enables its reciprocating oscillation. Thus, during reagent spraying, the reciprocating oscillation of the nozzle achieves multi-angle comprehensive coverage of the wound, avoiding the need for repeated instrument adjustments or multiple applications, thereby improving operational efficiency. Further, the drive assembly can apply impact force to the extruder during its interaction with the extruder, increasing the spray speed as the extruder pushes the reagent out of the nozzle. The coagulator allows the reagent to adhere to the wound in a sprayed state, enabling the entire nozzle to operate in a liquid environment, eliminating liquid interference. The impact spray action allows the reagent to smoothly pass through the liquid and quickly adhere to the wound, effectively ensuring the adhesion strength between the reagent and the wound surface, improving the efficiency and success rate of reagent adhesion, increasing surgical efficiency, and reducing surgical risks.

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0042] Please see the appendix Figure 1 - Appendix Figure 5 This embodiment relates to a coagulator. The coagulator includes a first module 1 and a second module 2. The first module 1 includes a container 11, one end of which has a working end 12. The container 11 is used to contain reagents, and the working end 12 is used to receive the flowing reagents and discharge them to the bone wound. The working end 12 includes a nozzle 121 and a connector 122. A squeezing member 133 is provided inside the container 11 for squeezing the reagents. The second module 2 is detachably connected to the first module 1. The second module 2 includes a drive assembly 21, which is driven to the connector 122 to reciprocate, causing the nozzle 121 to swing. The drive assembly 21 is also driven to the squeezing member 133 and impacts the squeezing member 133 to increase the spray speed of the reagents and discharge them from the nozzle 121.

[0043] It should be noted that this coagulator is particularly suitable for intraoperative and postoperative coagulation procedures in orthopedics, thoracic surgery, and neurosurgery to control wound bleeding. This embodiment uses bone wax as an example for detailed description, but bone wax is only a commonly used hemostatic agent. This coagulator can also be used to replace bone wax with other agents, such as gels. This coagulator is not limited to hemostatic applications with coagulating drugs; it can also be used for spraying or applying other medications. Specifically, this coagulator adopts a modular structure. The first module 1 is used to contain and release the reagent, allowing it to be accurately applied to the bleeding site on the bone wound for rapid hemostasis. The second module 2 has a handle-type configuration for easy handling by medical personnel and to align the first module 1 with the wound. Simultaneously, the second module 2 integrates a control structure, a power structure, and a power supply structure 24. The power supply structure 24 provides power to enable the first module 1 to perform various adjustment actions. The control structure faces the user, receiving the user's action commands to enable the first module 1 to complete the corresponding operation. The power structure receives electrical energy to drive the first module 1 to perform actions.

[0044] In this embodiment, the first module 1 is a disposable structure, while the second module 2 is a reusable structure that can be sterilized by high temperature. The first module 1 and the second module 2 are connected by a detachable connection method, such as plug-in, snap-fit, or conventional threaded fasteners, to facilitate users to quickly connect and disconnect the two.

[0045] Please see the appendix Figure 6 The container 11 includes a second sleeve 112 located on the outermost layer, and a first sleeve 111 located inside the second sleeve 112. The reagent can flow inside the first sleeve 111. The working end 12 includes a stator 123 and a nozzle 121. The stator 123 is connected to the end of the first sleeve 111 and is also a hollow structure. The nozzle 121 cooperates with the stator 123 and can swing relative to the stator 123. The stator 123 is used to support the nozzle 121 and, by cooperating with the nozzle 121, limits the swing trajectory of the nozzle 121. The second module 2 has a drive assembly 21, which can be electrically driven. The connector 122 is made of incompressible metal wire. The drive assembly 21 pulls the nozzle 121 to swing relative to the stator 123 within a certain angular range by pushing and pulling the connector 122. At the same time, the pushing and pulling action of the connector 122 enables the nozzle 121 to reciprocate. During the spraying process, the reciprocating oscillation of the nozzle 121 forms a comprehensive multi-angle coverage of the wound, avoiding the need for the user to repeatedly adjust the instrument position or apply multiple times, thus improving operational efficiency.

[0046] It should be noted that the fit between the nozzle 121 and the stator 123 can be achieved by machining a limiting groove on the stator 123, and rotatably connecting a portion of the nozzle 121 to the limiting groove. Under the traction of the connector 122, the nozzle 121 reciprocates relative to the stator 123, thereby enabling the nozzle 121 to swing within a certain angle range. Furthermore, in some applications, the nozzle 121 and the stator 123 can be fixed together. That is, in this embodiment, the swing transmission to the nozzle 121 can be cut off manually or automatically. For example, the transmission link between the drive assembly 21 and the connector 122 can be selectively cut off, allowing the nozzle 121 to remain fixed relative to the stator 123, thus concentrating the reagent sprayed by the nozzle 121 onto the designated area. Of course, when the nozzle 121 needs to swing for coating, the drive assembly 21 can still be selectively connected to the connector 122 manually or automatically to allow the nozzle 121 to swing.

[0047] Furthermore, the drive assembly 21 can also apply an impact force to the extruder 133 during its interaction with the extruder 133, thereby increasing the spray speed of the reagent through the nozzle 121 as the extruder 133 pushes the reagent. Many transmission mechanisms can achieve reciprocating impact force on the extruder 133. This embodiment will be described later using an elastic transmission mechanism as an example. By using a coagulator to allow the reagent to adhere to the wound surface in a sprayed state, the entire nozzle 121 can adapt to working in a liquid environment, eliminating liquid interference. Utilizing the impact spray action, the reagent smoothly passes through the liquid and quickly adheres to the wound surface, effectively ensuring the adhesion strength between the reagent and the wound surface, improving the efficiency and success rate of reagent adhesion to the wound surface, increasing surgical efficiency, and reducing surgical risks.

[0048] Optionally, the container 11 includes a heating tube 113, a first sleeve 111 is sleeved on the outside of the heating tube 113, and a flowable reagent is between the first sleeve 111 and the heating tube 113. The heating tube 113 is used to heat the reagent.

[0049] Specifically, the heating tube 113 is located inside the first sleeve 111, forming a gap between the heating tube 113 and the first sleeve 111 for reagent flow. The heating tube 113 heats the reagent using a central heating method to maintain good fluidity of the reagent within the long, straight tube through continuous heating. The heating tube 113 operates on a resistance heating principle, meaning that the inner wall of the heating tube 113 is provided with conductive lines extending axially. The container 11 has an interface 114 on the other side relative to the working end 12, which is used to electrically connect with the power supply structure 24 of the second module 2. After the first module 1 and the second module 2 are installed, the conductive lines simultaneously connect to the power supply module via interface 114. The heating start / stop and heating output power of the heating tube 113 can be controlled by a control unit integrated inside the second module 2. The specific control method is conventional technology and will not be described in detail in this embodiment.

[0050] In other embodiments, the heating function of the heating tube 113 can be adjusted according to the actual state of the reagent. The heating of the heating tube 113 can be controlled by a control unit, such as by controlling the heating curve and the heat preservation curve, to implement different heating and heat preservation states for different types of reagents, thereby improving adaptability. Even for some reagents, such as gels which are already flowable liquids at room temperature, the heating function can be adaptively turned off, meaning the user can directly and manually turn off the heating function of the heating tube 113, thus saving energy.

[0051] Furthermore, the first tube 111 can also be used as a heating tube, utilizing the thermal effect of resistance to circumferentially heat the reagent, thereby improving heating efficiency and ensuring heating uniformity.

[0052] In this embodiment, a heating tube 113 is integrated inside the container 11, and the reagent is continuously heated through the heating tube 113. This ensures that the reagent maintains continuous liquid flow during continuous use and avoids the problem of solidification and blockage.

[0053] Optionally, the first sleeve 111 is provided with a strip groove and / or a strip hole 1111 at the bend.

[0054] In this embodiment, the strip groove or strip hole 1111 allows the bent portion of the first sleeve 111 to bend and deform more quickly under unrestrained conditions.

[0055] In this embodiment, the second sleeve 112, which is sleeved outside the first sleeve 111, can also provide a heat preservation environment for the reagent between the first sleeve 111 and the heating tube 113, and the second sleeve 112 has a certain heat preservation effect.

[0056] Please see the appendix Figure 6 and attached Figure 7 Optionally, the end of container 11 away from working end 12 forms a connecting end 13. The connecting end 13 includes a fixing frame 131 and a heating cylinder 132. The heating cylinder 132 contains a reagent, and a squeezing element 133 is disposed in the heating cylinder 132 to squeeze the reagent in the heating cylinder 132 into the first sleeve 111.

[0057] Specifically, the fixing frame 131 has a shell-like structure and an open structure. At the same time, a heating cylinder 132 is provided inside the fixing frame 131. The outer wall of the heating cylinder 132 is provided or the interior is embedded with a resistance wire, thereby realizing the heating function of the heating cylinder 132. Solid reagents can be placed inside the heating cylinder 132 and melted by the heating action of the heating cylinder 132. The reagents in the heating cylinder 132 can flow into the first sleeve 111. Meanwhile, a movable extruder 133 is provided at the open end of the heating cylinder 132. The extruder 133 can be in the form of a sealed piston to prevent the reagent from overflowing. Through the extrusion and impact action of the extruder 133, the reagent can only be sprayed out at high speed from the nozzle 121.

[0058] Please see the appendix Figure 8 - Appendix Figure 10 Optionally, the first module 1 includes a housing 14, a container 11 located inside the housing 14, and a working end 12 extendable within the housing 14. When the working end 12 is located inside the housing 14, the extension direction of the working end 12 is consistent with the extension direction of the housing 14. When the working end 12 extends out of the housing 14, the extension direction of the working end 12 forms a preset bending angle with the extension direction of the housing 14, and the preset bending angle is not 0.

[0059] Specifically, the shell 14 encloses the container 11 inside. A portion of the shell 14 forms a guide steel pipe 141, and another portion forms a support 142. The guide steel pipe 141 is used to fit onto the second sleeve 112 of the container 11, and the support 142 is mounted on the fixing frame 131. The shell 14 provides support and protection for the container 11. The aforementioned interface 114 for electrical connection of the heating pipe 113 can be arranged inside the support 142.

[0060] The working end 12 of container 11 can extend and retract within the housing 14. A guide platform 1311 is provided on the outer wall of the fixing frame 131, and a guide groove 1421 is provided on the support 142. The guide platform 1311 is slidably connected to the guide groove 1421, allowing the fixing frame 131 to slide within the inner cavity of the support 142, thereby enabling the working end 12 located on one side to extend and retract within the housing 14. When the working end 12 extends beyond the housing 14, its extension direction forms a preset bending angle with the extension direction of the housing 14; this preset bending angle is not 0. After the working end 12 extends beyond the housing 14 to a preset distance, it bends according to the preset bending angle, thus giving the working end 12 a bending function. During the operation, the nozzle 121 is controlled to spray reagents at different angles and directions, further increasing the hemostasis range and operational flexibility.

[0061] It should be noted that the bending of the working end 12 is determined by the material properties of the working end 12 itself. That is, the first sleeve 111 and the second sleeve 112, which are made of elastic metal, are formed into a bent structure in a free state. When entering the housing 14, the working end 12 forms a straight state due to the constraint and restriction of the housing 14; when the working end 12 is outside the housing 14, the constraint and restriction of the housing 14 are released, and the working end 12 recovers to the preset bending angle through its own elasticity.

[0062] In some embodiments, the specific angle value of the preset bending angle is determined by the length value of the working end 12 extending out of the housing 14.

[0063] Specifically, the preset bending angle is positively correlated with the length of the working end 12 extending out of the housing 14. That is, the longer the working end 12 extends out of the housing 14, the larger the preset bending angle. This allows the working end 12 to be adjustable within a sufficient angle range. The adjustment method is simple and the adjustment range is larger, making it more practical.

[0064] Please see the appendix Figure 11 - Appendix Figure 14Optionally, the drive assembly 21 includes a drive member 211 and a camshaft 212 and a lever 213 that are pulverizedly connected to the drive member 211. The camshaft 212 is provided with a limiting groove 2121 in the circumferential direction. The lever 213 is partially slidably connected to the limiting groove 2121. The camshaft 212 rotates to make the lever 213 reciprocate along the axial direction. The lever 213 is pulverizedly connected to the connector 122.

[0065] Specifically, the drive component 211 can be a rotary motor capable of outputting rotational motion. The camshaft 212 is driven and connected to the drive component 211, which drives the camshaft 212 to rotate. A cam is provided on the camshaft 212, and the cam forms a limiting groove 2121 along the circumferential direction. The lever 213 is L-shaped and can be an integral or separate structure. In this embodiment, the lever 213 is limited in the circumferential direction and can only move axially. One end of the lever 213 is fixed in the limiting groove 2121, which has a sinusoidal or cosine extension path so that the lever 213 can reciprocate axially when the cam rotates. Thus, the rotational motion output of the drive component 211 forms a transmission form for the reciprocating movement of the lever 213, and further drives the connecting component 122 to reciprocate axially through the lever 213. The overall structure is simple and compact.

[0066] Optionally, the container 11 is provided with two elastic buttons 15 and two connectors 122 arranged side by side. One end of each connector 122 is connected to both ends of the nozzle 121, and the other end of each connector 122 is connected to the two elastic buttons 15. The lever 213 is connected to one of the elastic buttons 15 in a transmission connection.

[0067] Specifically, there are two elastic buttons 15, both of which are mounted on the fixing frame 131. The two elastic buttons 15 are located at the top and bottom of the fixing frame 131 respectively. Each elastic button 15 includes a button component 151 and a first elastic component 152 sleeved on the button. The lever 213 presses the button component 151 and compresses the first elastic component 152. The lever 213 releases the button component 151, and the first elastic component 152 drives the button component 151 to reset. Button 151 is slidably connected to the fixed frame 131. When the lever 213 presses the button 151, the button 151 will move toward the working end 12 and compress the first elastic element 152. At this time, the connector 122 that cooperates with the elastic button 15 pushes the nozzle 121 to rotate a certain angle. The other connector 122 adaptably compresses the other elastic button 15 in the opposite direction, so that the first elastic element 152 of the other elastic button 15 is compressed. When the lever 213 returns, the first elastic element 152 of the two elastic buttons 15 recovers its elasticity and drives the connector 122 to reset, so that the nozzle 121 rotates in the opposite direction by a certain angle. As the lever 213 moves axially back and forth, the nozzle 121 can be continuously oscillating.

[0068] In this embodiment, the stiffness of the first elastic element 152 of the two elastic buttons 15 can be the same or different, which can be determined according to the initial setting position of the nozzle 121.

[0069] Optionally, the drive assembly 21 also includes an elastic assembly 215 and an impact block 214. The camshaft 212 is rotatably connected to the impact block 214. The camshaft 212 rotates to compress the elastic assembly 215 to store energy. After being compressed to a preset position length, the energy is released and the impact block 214 is driven along the axial direction. The impact block 214 is used to impact the extruder 133.

[0070] Specifically, the drive assembly 21 includes a support member 216, the outer wall of which is provided with a protruding shaft 217. The second module 2 includes a housing 22 and a handle 23. The handle 23 is operably connected to the housing 22, and one end of the handle 23 located inside the housing 22 is hinged to the protruding shaft 217. By pressing the handle 23, the handle 23 pulls the protruding shaft 217, thereby moving the entire drive assembly 21 forward so that the working end 12 of the container 11 extends out of the guide tube 141. When the handle 23 is released, the handle 23 can be elastically reset, and the handle 23 pulls the protruding shaft 217 in the opposite direction, thereby moving the entire drive assembly 21 backward so that the working end 12 of the container 11 retracts into the guide tube 141.

[0071] Furthermore, the support member 216 internally houses a camshaft 212, an elastic assembly 215, and an impact block 214. The portion of the lever 213 that engages with the camshaft 212 is located within the support member 216, while the remaining portion of the lever 213 is located outside the support member 216. The drive member 211 is partially located outside the support member 216, with its drive end located within the support member 216 and rotatably connected to the camshaft 212. The integral drive assembly 21 is housed within the support member 216.

[0072] Optionally, the elastic assembly 215 includes a ratchet 2151, a second elastic element 2152, and a nut 2153. The two ends of the second elastic element 2152 are respectively connected to the ratchet 2151 and the nut 2153. The nut 2153 is threadedly connected to the camshaft 212. The ratchet 2151 is located inside the impact block 214. The impact block 214 cooperates with the ratchet 2151 to enable the energy storage and release of the second elastic element 2152.

[0073] In this embodiment, the impact block 214 is a cylindrical block, and the ratchet 2151 forms an annular structure at one end facing the second elastic member 2152. The ratchet 2151 is disposed inside the impact block 214, and the impact block 214 is in transmission cooperation with the annular structure and rotates according to the surface path of the annular structure. The impact block 214, ratchet 2151, second elastic member 2152, and nut 2153 are all sleeved on the camshaft 212. The camshaft 212 has an external thread of a certain length, and the nut 2153 is screwed to the camshaft 212. At the same time, the circumferential direction of the nut 2153 is constrained by the inner wall of the support member 216, thereby restricting the rotation of the nut 2153. Under the rotation of the camshaft 212, the nut 2153 can only move axially to compress the second elastic member 2152. The impact block 214 is sleeved on the camshaft 212, and the camshaft 212 and the impact block 214 are connected by a key. Therefore, the impact block 214 can rotate synchronously with the camshaft 212.

[0074] In this embodiment, the adjustment of the reagent impact amount can be achieved by changing the pre-deformation of the second elastic element 2152 and the output rotation speed of the drive element 211. For example, when it is necessary to increase the reagent impact amount, this can be achieved by manually increasing the pre-deformation of the second elastic element 2152—the initial compression—and / or by automatically controlling the rotation speed of the drive element 211. For adjusting the impact amount, one can choose from the above two options or adjust using a combination of the above two options based on the convenience of the adjustment scheme and the range of the adjusted impact amount.

[0075] In this embodiment, the camshaft 212 rotates to drive the nut 2153 to compress the second elastic element 2152. At the same time, the camshaft 212 drives the impact block 214 to rotate along the annular structure of the ratchet 2151. The annular structure includes a gently sloping rising portion 2151a and a steeply sloping descending portion 2151b. In the rising portion 2151a, the second elastic element 2152 is continuously compressed and stores energy. When it passes the rising portion 2151a and reaches the descending portion 2151b, the elasticity of the second elastic element 2152 is released instantaneously, providing the impact block 214 with a large impact acceleration and impact force. The impact block 214 then impacts the extruder 133, enabling the extruder 133 to quickly impact the reagent and increase the spray speed of the reagent. Since the impact block 214 is relatively short, in order to accommodate the distance between the impact block 214 and the extrusion member 133, a linkage block 218 can be set between the impact block 214 and the extrusion member 133. The two ends of the linkage block 218 abut against the impact block 214 and the extrusion member 133 respectively, and are used to transmit the impact force.

[0076] It should be noted that by adjusting and optimizing the rotational engagement shape between the ratchet 2151 and the impact block 214, intermittent spraying of the nozzle 121 can be achieved. Furthermore, by adjusting the structure and quantity of the rising part 2151a and the falling part 2151b, the number of impacts per revolution of the camshaft 212 can be easily adjusted, thereby achieving intermittent adjustment of the spraying of the nozzle 121.
