Technical Field

[0001] This invention relates to the field of nail surgical instruments, and more specifically, to an adjustable depth punching sampler and its method of use. Background Technology

[0002] In clinical surgeries involving the nails, such as those treating nail bed damage caused by trauma, decompression of subungual hematomas, and treatment of subungual hemangiomas, the surgical nail needs to be removed and a hole made for drainage. The current method is to use alcohol to burn a paperclip to make a hole. The disadvantages are that it is prone to infection (because the operating site needs to be changed), and the hole made by burning may not drain well, be uneven, damage the nail bed, and not grow well. Summary of the Invention

[0003] The main objective of this invention is to provide an adjustable depth punch sampler and its usage method to solve the problems in related technologies.

[0004] To achieve the above objectives, according to one aspect of the present invention, an adjustable depth drilling sampler and its method of use are provided, comprising a drill bit and a drive unit for driving the drill bit to rotate, wherein the outer surface of the drill bit is provided with scale lines, the drill bit is a hollow structure, and further comprising;

[0005] The drill bit is mounted on a negative pressure section, which is connected to the hollow area of ​​the drill bit. The negative pressure section is capable of generating negative pressure and sucking up drilling debris from the hollow area of ​​the drill bit.

[0006] Furthermore, the drive unit includes a drive head and a drill bit drive motor installed inside the drive head, the drill bit drive motor being connected to the drill bit for driving.

[0007] Furthermore, the interior of the drive head is hollow, and the drive head is connected to the air inlet of the negative pressure section to form a communicating area.

[0027] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0028] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, 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, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] An adjustable depth punch sampler, such as Figure 1-2 It includes a drill bit 2 and a drive unit that drives the drill bit 2 to rotate. The outer surface of the drill bit 2 is provided with scale lines. The drill bit 2 has a hollow structure and also includes a negative pressure unit. The drill bit 2 is mounted on the negative pressure unit. The negative pressure unit is connected to the hollow area of ​​the drill bit 2. The negative pressure unit can generate negative pressure and suck up drilling debris from the hollow area of ​​the drill bit 2.

[0032] See Figure 4 , Figure 5 , Figure 6The drive unit includes a drive head 3 and a drill drive motor 9 installed inside the drive head 3. Specifically, the drive head 3 is a hollow cylindrical structure with an annular support 301 inside. The drill drive motor 9 is fixed to the support 301 by bolts. The annular support is hollow all around to allow debris to pass through smoothly. The drill drive motor 9 is connected to the drill bit 2 for drive. The drive head 3 is connected to the air inlet 6 of the negative pressure unit to form a communication area. The middle of the end of the drill bit 2 near the drive head 3 is a solid area, and a keyway 202 connected to the output shaft of the drill drive motor 9 is provided in this solid area. Air holes 201 are provided at intervals around the solid area to communicate with the interior of the drive head 3. In this embodiment, as shown... Figure 4 As shown, the air vent 201 consists of several round holes arranged around the solid area, which can ensure basic communication function and ensure that the drilling debris enters the drive head 3 under negative pressure and thus enters the negative pressure section.

[0033] like Figure 3 As shown, the negative pressure unit includes a body 1. A handle 4 is located at the rear of the body 1, allowing the entire device to be held for drilling operations. The body 1 has a hollow structure, housing a fan 8, and a filter 7 is detachably installed near the air inlet 6. Specifically, the front and rear halves of the body 1 are snap-fitted together. The fan 8 is installed in the rear half, while the filter 7 is installed in the front half. The filter 7 can be removed for sampling or cleaning. The rear half contains a battery compartment, where a battery 5 is directly inserted for power. The battery 5 is a lithium battery, using a direct-plug power supply, making battery replacement very convenient and suitable for clinical use.

[0034] It should be noted that the drilling end of drill bit 2 has multiple helical grooves 203 spaced apart, which increases the friction between drill bit 2 and the fingernail, improving drilling efficiency. To prevent debris from flying outwards during drilling, the drilling end of drill bit 2 has a triangular cross-section, with an inclined inner surface and a straight outer surface. This causes the debris generated during drilling to gather inwards at the inward-sloping angle and be directly sucked away from the hollow part of drill bit 2, preventing contamination.

[0035] Example 2:

[0036] Based on Example 1, the inventors discovered a new problem: although the circular holes around the solid area of ​​drill bit 2 in Example 1 were densely distributed, nail clippings easily accumulated in the solid area connecting the holes when they entered. This caused them to clump together and gradually block the holes when the air was humid. Since the internal space of drill bit 2 was limited, cleaning was very inconvenient, requiring periodic replacement of the drill bit. Therefore, the inventors continued to improve the structure based on Example 1, such as... Figure 7 , 8As shown, the solid area in the middle of one end of the drill bit 2 is replaced with a connecting shaft 204, and the keyway 202 is opened on the back of the connecting shaft 204. The drill bit 2 and the connecting shaft 204 are then connected by several connecting ribs 205, forming a guide area that is larger in the drill bit 2 and smaller in the connecting shaft 204. The inner wall of the connecting ribs 205 is made into a smooth streamline shape, and the hollow part between each connecting rib 205 forms a vent 201. The front of the connecting shaft 204 is made into a round convex shape with a high center and low periphery, i.e., a protrusion 206, to ensure that the airflow is completely guided into the vent 201 area. In this way, compared with embodiment 1, the area of ​​the vent 201 is greatly increased, the airflow direction is changed, and the ventilation part no longer has a flat obstruction area, but is all curved streamline shape, which can effectively prevent the problem of nail clippings clogging.

[0037] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
