Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a single-polar flushing device. Background Technology

[0002] In the field of modern surgery, monopolar irrigators, as surgical devices integrating monopolar electrosurgery (electrosurgical cutting / electrocoagulation) and irrigation functions, are mainly used in surgical procedures to simultaneously perform cutting, hemostasis, and wound irrigation, thereby improving surgical efficiency and visual clarity. However, the working parts of monopolar irrigators are reusable consumables due to cost considerations. Furthermore, tissue scabs and residues inevitably form after cutting, and the replacement of working parts in existing monopolar irrigators is inconvenient, leading to difficulties in cleaning the working parts. Utility Model Content

[0003] The purpose of this utility model is to provide a single-pole flushing device that enables quick installation and disassembly of the working parts of the single-pole flushing device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a single-stage flushing device, including a working component, an installation structure, and a fixing structure. The installation structure is connected to the end of the single-stage flushing device through the fixing structure, and the working component is connected to the installation structure through a detachable connection structure.

[0006] Preferably, the detachable connection structure is a threaded connection structure, including an internal thread on the working part and an external thread on the mounting structure, wherein the internal thread and the external thread are screwed together.

[0007] Preferably, the detachable connection structure is a snap-fit ​​connection structure, including an elastic snap-fit ​​part on the working part and a snap-fit ​​groove on the mounting structure. When the working part is assembled into the mounting structure, the elastic snap-fit ​​part undergoes elastic deformation and is embedded in the snap-fit ​​groove to form a locking fit.

[0008] Preferably, the elastic buckle portion has an inwardly extending spherical protrusion, and the snap-fit ​​groove is a hemispherical groove that matches the shape of the spherical protrusion.

[0009] Preferably, the assembly end of the mounting structure is provided with a guide surface, which is an arc surface or an inclined surface.

[0010] Preferably, the mounting structure includes: a base connected to the working part and a limiting structure connected to the fixing structure, wherein the base and the limiting structure are fixedly connected.

[0011] Preferably, the base and the limiting structure are fixedly connected by riveting.

[0012] Preferably, the limiting structure is provided with a limiting boss extending radially along the limiting structure, and the base has an abutting surface that abuts and engages with the limiting boss.

[0013] Compared with the prior art, this utility model has significant progress:

[0014] The monopolar irrigator of this invention has a detachable connection between the working part and the mounting structure. When the working part is damaged or worn, only the working part needs to be replaced instead of the entire monopolar irrigator, thereby reducing the cost of using the device and reducing the waste of medical resources. At the same time, the disassembled working part can be more conveniently cleaned and disinfected, which helps to maintain the cleanliness and hygiene of the device and reduce the risk of surgical infection.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0024] Example 1

[0025] like Figures 1 to 3 The image shown is a first embodiment of the single-stage flushing device provided by this utility model.

[0026] The single-pole flusher of this embodiment includes a working component 1, an installation structure 2, and a fixing structure 3. The installation structure 2 is connected to the end of the single-pole flusher through the fixing structure 3, and the working component 1 is connected to the installation structure 2 through a detachable connection structure.

[0027] The working component 1 is the functional part of the single-stage irrigation device. Working component 1 is assembled with the mounting structure 2 via a detachable connection, allowing for quick replacement according to the needs of the actual surgery. For example, when working component 1 becomes worn, damaged, or requires a different type of working component 1, it can be disassembled and replaced to meet different surgical requirements. Furthermore, the disassembled working component 1 allows for easier cleaning and disinfection during cleaning and maintenance.

[0028] Mounting structure 2 effectively connects working part 1 and other parts of the single-stage flusher, making the single-stage flusher a whole, ensuring the normal assembly and use of the single-stage flusher. At the same time, mounting structure 2 also provides a stable installation position and connection relationship for working part 1, ensuring that working part 1 can function stably during use.

[0029] The fixing structure 3 fixes the mounting structure 2 to the end of the single-stage flusher, providing a solid support and positioning for the mounting structure 2, so that the mounting structure 2 can be stably connected to the single-stage flusher, thereby ensuring the stability of the installation and use of the working part 1.

[0030] Therefore, the working part 1 and the mounting structure 2 are assembled through a detachable connection structure. When the working part 1 is damaged or worn, only the working part 1 needs to be replaced instead of the entire monopolar irrigator, thereby reducing the cost of using the instrument and reducing the waste of medical resources. At the same time, the disassembled working part 1 can be more conveniently cleaned and disinfected, which helps to keep the instrument clean and hygienic and reduce the risk of surgical infection.

[0031] See Figure 3In this first embodiment, preferably, the detachable connection structure is a threaded connection structure, including an internal thread on the working part 1 and an external thread on the mounting structure 2, with the internal and external threads screwed together. When the working part 1 needs to be installed on the mounting structure 2, first align the central axes of the working part 1 and the mounting structure 2, and then screw the working part 1 onto the mounting structure 2 in the same direction, so that the internal and external threads fit tightly to complete the connection; when the working part 1 needs to be disassembled, rotate the working part 1 in the opposite direction to unscrew it from the mounting structure 2, thereby achieving detachability. The use of a threaded detachable structure allows the working part 1 to be quickly and easily connected and disassembled with the mounting structure 2, improving the flexibility of use and ease of maintenance of the single-stage flusher.

[0032] See Figure 3 In this first embodiment, preferably, the mounting structure 2 includes a base 23 connected to the working part 1 and a limiting structure 24 connected to the fixing structure 3. The base 23 and the limiting structure 24 are fixedly connected. One end of the base 23 connected to the working part 1 has an external thread, which tightly engages with the internal thread of the working part 1, ensuring the working part 1 is securely mounted on the base 23. The other end of the base 23 is fixedly connected to the limiting structure 24, preventing axial and radial movement of the base 23. This ensures the mounting structure 2 forms a stable whole, guaranteeing the stability and reliability of the working part 1 during use. Simultaneously, the mounting structure 2, connected to the fixing structure 3 via the limiting structure 24, restricts its position on the single-stage flusher, improving the overall integrity of the single-stage flusher.

[0033] See Figure 3 In this first embodiment, preferably, the base 23 and the limiting structure 24 are fixedly connected by a riveting fit. Specifically, a riveting hole is formed through the side wall of the limiting structure 24 along the radial direction of the limiting structure 24. A rivet is inserted into the riveting hole and then riveted, thereby tightly fixing the base 23 and the limiting structure 24 together. The stability of the riveting fit ensures that the connection between the base 23 and the limiting structure 24 will not loosen due to long-term use or vibration, thereby improving the reliability of the entire mounting structure 2.

[0034] See Figure 3In this first embodiment, preferably, the limiting structure 24 is provided with a limiting boss 241 extending radially along the limiting structure 24, and the base 23 has an abutment surface 231 that abuts against the limiting boss 241. The limiting boss 241 and the abutment surface 231 abut against each other, thereby restricting the relative movement between the base 23 and the limiting structure 24, and limiting the base 23 axially, so that the base 23 and the limiting structure 24 are stably connected. At the same time, the cooperation between the limiting boss 241 and the abutment surface 231 provides a clear positioning for the base 23 and the limiting structure 24 during assembly, ensuring that the two can be accurately aligned during installation, which facilitates assembly.

[0035] Example 2

[0036] like Figures 4 to 6 The image shows a second embodiment of the single-stage flushing device provided by this utility model. Embodiment two is basically the same as embodiment one, and the similarities will not be repeated. The difference lies in that, in this embodiment two, the detachable connection structure is a snap-fit ​​connection structure, including an elastic snap-fit ​​part 11 provided on the working part 1 and a snap-fit ​​groove 21 provided on the mounting structure 2. When the working part 1 is assembled onto the mounting structure 2, the elastic snap-fit ​​part 11 undergoes elastic deformation and embeds into the snap-fit ​​groove 21 to form a locking fit. The snap-fit ​​connection structure relies on the elastic deformation of the elastic snap-fit ​​part 11 to achieve connection and locking. When the workpiece 1 is assembled onto the base 23, the elastic latching part 11 presses against the side wall of the base 23, and the elastic latching part 11 deforms outward under the action of the side wall of the base 23. As the base 23 is further assembled, the elastic latching part 11 moves to the position corresponding to the locking groove 21. Then, the elastic latching part 11 returns to its original shape and embeds into the locking groove 21, forming a locking fit to prevent the workpiece 1 from detaching from the base 23. During disassembly, by applying appropriate external force (such as pulling or rotating the workpiece 1), the elastic latching part 11 undergoes elastic deformation again, allowing it to disengage from the locking groove 21, thus achieving rapid separation of the workpiece 1 from the base 23. The elastic latching part 11 is made of a material with a certain degree of elasticity, and the elastic deformation and recovery process of the elastic latching part 11 is reversible, providing a basis for disassembly. The latching connection structure allows for rapid assembly and disassembly between the workpiece 1 and the base 23 without tools; only appropriate force is needed to complete the connection or separation, improving operational convenience.

[0037] See Figure 4 and Figure 6In this second embodiment, preferably, the elastic buckle 11 has an inwardly extending spherical protrusion 111, and the locking groove 21 is a hemispherical groove adapted to the shape of the spherical protrusion 111. When the workpiece 1 is assembled onto the base 23, the spherical protrusion 111 on the elastic buckle 11 presses against the side wall of the base 23. The elastic buckle 11 deforms outward during this pressing action. As the base 23 is assembled further, the spherical protrusion 111 on the elastic buckle 11 moves to a position corresponding to the locking groove 21. Since the shape of the spherical protrusion 111 is adapted to the hemispherical locking groove 21, the spherical protrusion 111 is embedded in the locking groove 21 and springs back. The elastic buckle 11 returns to its original shape, thus forming a locking fit. When it is necessary to disassemble the working part 1, pull or rotate the working part 1. Since the mating surface between the spherical protrusion 111 and the locking groove 21 is an arc surface, under the action of appropriate external force, the spherical protrusion 111 disengages from the locking groove 21 along the arc surface. Then, the mutual compression between the spherical protrusion 111 and the side wall of the base 23 causes the elastic buckle 11 to deform outward and continue to pull the working part 1 away from the base 23, thereby realizing the rapid separation of the working part 1 from the base 23.

[0038] See Figure 4 and Figure 6 In this second embodiment, preferably, the assembly end of the mounting structure 2 is provided with a guide surface 22, which is an arc surface or an inclined surface. The guide surface 22 is located on the base 23 of the mounting structure 2. When the workpiece 1 is assembled onto the base 23, the spherical protrusion 111 on the elastic latching part 11 first contacts the guide surface 22. As the workpiece 1 continues to be assembled towards the base 23, the elastic latching part 11 undergoes elastic deformation under the interaction of the spherical protrusion 111 and the guide surface 22, gradually tilting towards the outer periphery. The arc or inclined surface design of the guide surface 22 allows the elastic latching part 11 and the spherical protrusion 111 to smoothly transition to contact and press against the outer wall of the base 23.

[0039] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
