Description

Technical Field

[0001] This utility model relates to the field of pathogen inoculation technology, specifically to a pathogen inoculation puncture device. Background Technology

[0002] Inoculation with pathogenic fungal cakes through wounds is an important experimental technique in plant pathology research for verifying pathogenicity. Its core lies in artificially simulating natural infection conditions to observe the pathogen's ability to infect host tissues. During the procedure, a penetrating wound with a diameter of 3-5 mm is created on the surface of host tissues such as fruits and leaves using a sterile needle or punch, reaching the tissue layer below the epidermis, simulating natural insect infestation or mechanical damage. Then, a fungal cake prepared under sterile conditions is tightly adhered to the host wound and secured with sterile cotton balls or sealing film to prevent the fungal cake from falling off and to maintain local humidity.

[0003] The above operations require the use of a needle to perform punctures on the host. In practice, it has been found that when using a single needle to perform punctures, it is often necessary to repeatedly puncture multiple locations on the host with the same needle to create the required number of wounds. During the repeated punctures at multiple points, it is difficult to maintain consistent pressure, and it is also impossible to ensure that the depth and spacing of each puncture are consistent. This results in varying puncture depths and spacing, which affects the effective invasion of pathogens at the wound sites.

[0004] Therefore, a pathogen inoculation puncture device that is simple in structure, easy to operate, and capable of creating multiple puncture wounds on the host in one go with consistent wound depth and regular spacing, and that allows for needle replacement according to the shape of the host, along with a multi-needle structure suitable for acupuncture, effectively improves the acupuncture effect and ensures that pathogens can effectively invade the wound site in the later stage, has broad market prospects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a pathogen inoculation puncture device that is simple in structure, easy to operate, capable of creating multiple puncture wounds on the host in one go, with consistent wound depth and regular spacing, and allows for needle replacement according to the shape of the host. It is equipped with a multi-needle structure suitable for acupuncture, effectively improving the acupuncture effect and ensuring that pathogens can effectively invade the wound site in the later stage. This invention overcomes the defects in existing technologies.

[0006] The technical solution of this utility model is implemented as follows: a pathogen inoculation puncture device includes a needle handle, an external threaded plug is fixedly installed at the bottom end of the needle handle, a replaceable needle mounting seat is movably installed on the external threaded plug, and a plurality of puncture needles arranged in an array are fixedly installed at the bottom of the replaceable needle mounting seat.

[0007] The top of the needle handle has an arc-shaped structure, and an anti-slip layer is provided in the middle of the needle handle.

[0008] The length of the external threaded plug shall not exceed the length of the replaceable needle mounting base.

[0009] The needle handle is cylindrical, and the replaceable needle mounting base is also cylindrical. The diameter of the replaceable needle mounting base is no greater than the diameter of the needle handle.

[0010] The top of the replaceable needle mounting base is provided with a cover close-fitting ring, and a cover is movably installed on the cover close-fitting ring. The cover is a cylindrical structure with a top diameter that matches the diameter of the needle handle, and the inner diameter of the cover matches the outer diameter of the cover close-fitting ring.

[0011] The top of the replaceable needle mounting base is provided with a cylindrical slot, and an internal thread layer that mates with the outer wall of the external threaded plug is provided in the cylindrical slot.

[0012] The cover and the fitting ring are cylindrical in shape. The diameter of the cover and the fitting ring is not greater than the diameter of the needle handle. The diameter of the cover and the fitting ring is not less than the diameter of the replaceable needle mounting base. The lower part of the replaceable needle mounting base is a sloping structure. The puncture needles are evenly distributed on the bottom surface of the replaceable needle mounting base.

[0013] The number of puncture needles is 5-10.

[0014] This utility model has the following positive effects:

[0015] 1. This product utilizes a replaceable needle holder that integrates multiple puncture needles for connection with the needle handle. The connection method is a threaded connection. There are multiple replaceable needle holders, which can be replaced according to specific usage needs. Different replaceable needle holders have different numbers and lengths of puncture needles, which are used for different puncture operations on flat or curved host surfaces. During use, multiple wounds on the host surface can be created with a single puncture action, eliminating the need for repeated punctures and ensuring the spacing between wounds. Especially when performing puncture operations on flat host surfaces, it not only ensures the spacing of puncture wounds but also ensures that the depth of multiple wounds is consistent, improving work and operation efficiency.

[0016] 2. This product features an anti-slip layer to ensure stability when holding the needle handle. The replaceable needle holder has a cylindrical structure with a diameter smaller than the needle handle diameter, improving accuracy during puncture and allowing for precise needle insertion at preset locations. The cover is securely fastened to the fitting ring, providing external protection for the needle when not in use. The top of the replaceable needle holder has an internal thread cavity that mates with the external thread layer on the outer wall of the external threaded plug, enabling a threaded connection. The lower part of the replaceable needle holder has a sloped structure, improving visual observation during puncture and increasing needle insertion efficiency. The number of needle insertions varies depending on the replaceable needle holder, allowing for selection based on specific needs. Attached Figure Description

[0025] Specifically, this product integrates several puncture needles 7 evenly distributed below the replaceable needle mounting base 5. The puncture needles 7 are set at the bottom of the needle handle 1 by means of a threaded connection between the replaceable needle mounting base 5 and the external threaded bolt 4. An anti-slip layer 2 is provided to enhance the stability when holding the needle handle. The whole product adopts a movable installation method, and multiple replaceable needle mounting bases 5 are connected and installed. Different replaceable needle mounting bases 5 are installed according to the needs, and different numbers of puncture needles 7 are selected for use.
