Description

Technical Field

[0001] This disclosure generally relates to the field of sampling instruments, and more particularly to a standardized muscle cutting tool. Background Technology

[0002] When conducting poultry muscle quality testing or scientific research experiments, it is necessary to obtain muscle strip samples with uniform specifications and good activity, especially poultry breast meat. Due to the differences in fiber direction and tissue density, higher requirements are placed on the accuracy of slicing and the efficiency of operation.

[0003] Currently, the industry mostly uses scalpels or scissors to cut poultry muscles. This method relies on the operator's visual inspection, which makes it difficult to ensure that the cut strips are of consistent size, easily leading to errors that affect the test results. Furthermore, it requires repeated cutting and trimming, which can damage the original shape of the muscle and interfere with the final test results. Utility Model Content

[0004] To address the aforementioned problems in related technologies, this disclosure provides a standardized muscle cutting tool.

[0005] According to some embodiments of this disclosure, a standardized muscle cutting tool is provided, comprising:

[0006] The handheld part has a semi-circular structure, and its two ends are connecting ends;

[0007] Multiple cutting tools, each having two ends connected to one of the two connecting ends.

[0008] The plurality of cutting tools are spaced apart, and the extension directions of the plurality of cutting tools are parallel to each other.

[0009] In some embodiments, the handheld portion includes a plurality of walls, the intersecting portions of which are chamfered planes or curved surfaces.

[0010] In some embodiments, the end of the handheld part is provided with a connecting groove, the end of the blade is located in the connecting groove, the connecting groove includes two opposing first sidewalls, the two first sidewalls are respectively disposed on both sides of the blade, and restrict the blade from displacing relative to the handheld part in a direction perpendicular to the extension of the blade.

[0011] In some embodiments, the connecting groove includes a second sidewall that abuts against the end of the blade to prevent the blade from displacing relative to the handle along the extension direction of the blade.

[0012] In some embodiments, the end of the cutting tool is detachably connected to the connecting end.

[0013] In some embodiments, the cutting tool and the connecting end can be one or more of the following: snap-fit ​​connection, magnetic connection, screw connection, interference fit connection, and adhesive connection.

[0014] In some embodiments, the standardized muscle cutting tool further includes fasteners;

[0018] In some embodiments, the end of the fastener is flush with the port face of the first through hole, or

[0019] The end of the fastener is embedded in the first through hole.

[0020] In some embodiments, the cutting tool includes a blade that protrudes from the edge of the handle portion, such that the blade is spaced at a predetermined distance from the connecting end.

[0021] In some embodiments, the standardized muscle cutting tool further includes a pad that is detachably connected to the connecting end to change the preset distance.

[0022] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: By designing the handheld part as a semi-circular structure and setting two parallel blades at the two connecting parts of the handheld part to form a closed structure, this disclosure improves the torque resistance and structural strength, while making the point of force exerted by the user when holding the handheld part close to the vertical line of the center of gravity of the cutting tool, so that the user can exert force to cut muscle tissue, thereby achieving equal width cutting sampling of muscle tissue.

[0023] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0030] The principles and spirit of this disclosure will now be described with reference to several exemplary embodiments. It should be understood that these embodiments are given merely to enable those skilled in the art to better understand and implement this disclosure, and are not intended to limit the scope of this disclosure in any way.

[0031] It should be noted that although the terms "first," "second," etc., are used herein to describe different modules, steps, and data in the embodiments of this disclosure, these terms are only for distinguishing between different modules, steps, and data, and do not indicate a specific order or degree of importance. In fact, the terms "first," "second," etc., can be used interchangeably.

[0032] The standardized muscle cutting tool provided in this disclosure is a cutting tool for cutting and sampling muscle tissue. It is particularly suitable for the preparation of strip muscle samples in poultry muscle quality testing or scientific research experiments. It can cut poultry muscles such as chicken breast into strips to obtain muscle strip samples with uniform specifications and good activity, so as to meet the requirements of subsequent testing or experiments for sample accuracy and quality.

[0033] In related technologies, the operation of cutting poultry muscle strips mostly relies on ordinary scissors. Although scissors can achieve basic cutting functions, this method of cutting strips depends on the operator's visual inspection, which makes it difficult to ensure that the strip specifications are consistent and prone to errors, thus affecting the test results. Furthermore, a complete muscle strip often requires the operator to trim it multiple times, which can easily damage the original shape of the muscle and interfere with the final test results.

[0034] Figure 1This is a front view of a standardized muscle cutting tool according to an exemplary embodiment. Figure 2 This is a side view of a standardized muscle cutting tool according to an exemplary embodiment.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, the standardized muscle cutting tool includes a handle 10 and multiple blades 20. The handle 10 serves as the part for the user to hold the cutting tool and also provides a mounting base for the blades 20. The blades 20 are cutting components that directly contact the object being cut. Multiple blades 20 can be used. The multiple blades 20 extend in parallel directions and are spaced apart. By fixing the spacing between the blades 20, the width of the cut muscle strips can be made the same as the spacing between the blades 20, thereby improving the consistency of the width of chicken strips cut multiple times.

[0036] The handle 10 has a semi-circular structure, which better fits the hand's grip posture, distributes the force on the hand, and avoids hand fatigue caused by prolonged operation. The two ends of the semi-circular structure of the handle 10 are connecting ends 11, which are connected to the two ends of the blade 20. The semi-circular structure and the blade 20 together form a closed structure. The closed structure provides rigidity and torsional resistance, thereby improving torque resistance and structural strength. At the same time, it makes the force point of the user pressing down on the handle 10 close to the vertical line of the cutting tool's center of gravity, so that the user can press down to cut muscle tissue and achieve equal-width cutting sampling of muscle tissue.

[0037] Furthermore, when the user is holding the cutting tool, the handle is located above the blade 20, and the force exerted by the hand is in the same direction as the cutting direction of the blade, which can reduce wrist torque and improve the user's force exertion efficiency.

[0038] In some embodiments, such as Figure 1 As shown, the handheld part 10 can be combined with the blade 20 to form a hollow part 15. The hollow part 15 can reduce the weight and make it easier for gloved fingers to enter and grip, so that the user can grip the cutting tool, reduce user hand fatigue, improve user operating comfort, and compared with other long-handled cutting tools, it can prevent fingers from sliding up and touching the blade edge 21, thus improving the operating safety of the cutting tool.

[0039] In some embodiments, the handle 10 may include multiple walls, the intersecting portions of which are chamfered planes or curved surfaces. The walls can be any of the outer planes or curved surfaces of the handle 10. By chamfering the intersecting portions of the outer walls of the handle 10, the pressure and pain on the user's hand caused by sharp edges can be avoided. Furthermore, the chamfered structure prevents small, hard-to-clean corners from appearing in the handle 10, reducing cleaning dead zones and facilitating cleaning of the cutting tool.

[0040] In some embodiments, the inner corners of the cutout portion 15 can be designed as arc-shaped structures and have reserved drainage channels to reduce the presence of recessed structures and clean dead corners, so as to facilitate the cleaning and drying of the cutting device and prevent debris or liquid from accumulating in the recessed structures or corners.

[0041] In some embodiments, the material of the handheld part 10 may be polypropylene (PP), glass fiber reinforced polyamide (GF+PA), polyether ether ketone (PEEK), and medical photosensitive resin. The handheld part 10 made of the above materials can withstand alcohol disinfection, hydrogen peroxide disinfection and steam sterilization, meet the cleaning and disinfection requirements of the tool in the testing or experimental scenario, and avoid the deterioration of material performance due to the disinfection process.

[0042] In some embodiments, the wall surface of the handgrip 10 may be provided with anti-slip textures or anti-slip dot matrix to reduce slippage when the user holds the handgrip 10, so that the user can hold the cutting tool stably when wearing gloves or when it is contaminated with liquid or grease.

[0043] In some embodiments, such as Figure 1 As shown, the handheld part 10 has an axisymmetric structure in both the extension direction of the blade 20 and the extension direction perpendicular to the blade 20, so that the user can choose to hold the cutting tool with either the left or right hand, and there is no need to distinguish between the front and back directions when holding it, which makes it convenient for the user to operate.

[0044] In some embodiments, the side of the handheld part 10 away from the blade 20 can be a flat surface to provide the user with a larger area for applying force and pressing, thereby improving the efficiency of the user pressing and cutting muscles.

[0045] In some embodiments, the handle 10 may have a hollow structure inside, and reinforcing ribs may be provided in the hollow structure. This reduces the weight of the handle 10 and increases its torsional stiffness, ensuring that the handle 10 does not deform when the user applies force to cut, and that the position of the blade 20 does not twist or shift, thereby ensuring that the cut muscle strips are regular in shape and consistent in size.

[0046] In some embodiments, the end plane of the connecting end 11 may be parallel to the thickness direction of the cutting tool 20, thereby providing a reference for the user, helping to keep the conductor perpendicular to the muscle tissue, and improving the parallelism of the cut.

[0047] Figure 3 This is a bottom view of a standardized muscle cutting tool according to an exemplary embodiment.

[0048] In some embodiments, such as Figure 3 As shown, the end of the handheld part 10 may be provided with a connecting groove 12, and the end of the blade 20 may be located in the connecting groove 12. The connecting groove 12 may include two opposing first sidewalls 13. The two first sidewalls 13 may be respectively provided on both sides of the blade 20 and abut against the side of the blade 20 to limit the displacement of the blade 20 relative to the handheld part 10 in the direction perpendicular to the extension of the blade 20. This reduces the displacement of the blade 20 due to the lateral force perpendicular to the length direction of the blade 20, which may cause deviation in the cutting spacing, thereby ensuring that the muscle strip specifications are consistent.

[0049] In some embodiments, such as Figure 3 As shown, the connecting groove 12 may also include a second sidewall 14, which may abut against the end of the blade 20 to prevent the blade 20 from displacing relative to the hand-held part 10 along the extension direction of the blade 20. This can reduce the back-and-forth sliding of the blade 20 relative to the hand-held part 10 when the user performs back-and-forth dragging cutting operations, thereby improving the sliding cutting performance of the cutting tool.

[0050] In some embodiments, the end of the cutting tool 20 is detachably connected to the connecting end 11. This detachable connection allows for complete separation of the cutting tool 20 and the connecting end 11, enabling separate and thorough high-temperature sterilization of the connection point. This effectively eliminates sterilization dead zones created by the connection structure, ensuring the cleanliness of the cutting tool during repeated use and meeting the stringent sterilization requirements of experimental or testing scenarios. Furthermore, the handle 10 can be reused by disassembling and replacing the cutting tool 20.

[0051] In some embodiments, the blade 20 and the connecting end 11 can be one or more of the following: snap-fit ​​connection, magnetic connection, screw connection, interference fit connection, and adhesive connection.

[0052] When using a snap-fit ​​connection, the blade 20 can be quickly engaged or disengaged from the connecting end 11 via the snap-fit ​​structure, enabling convenient assembly and disassembly of the blade 20 and improving operational efficiency.

[0053] When using magnetic connection, the magnetic attraction force is used to position and fit the cutting tool 20 with the connecting end 11, which can not only ensure assembly stability, but also reduce mechanical wear during disassembly and assembly, and extend the service life of the parts.

[0054] When using screw 31 for connection, the screw 31 locks the blade 20 to the connection end 11 through the thread fastening action. The fastening force can be adjusted as needed to ensure that the blade 20 does not loosen during the cutting process, thereby improving the structural reliability.

[0055] When using an interference fit, a tight connection is achieved by means of the interference fit between the end of the cutting tool 20 and the mating surface of the connecting end 11, eliminating the need for additional fasteners 30. This simplifies the structure while ensuring a tight connection and reducing cleaning dead zones.

[0056] When adhesive bonding is used, the cutting tool 20 is fixed to the connecting end 11 by using a suitable adhesive, which can improve the integrity of the connecting part, avoid gaps, and adapt to the miniaturized structural design to meet the needs of compact tool layout.

[0057] Figure 4 This is a perspective view of a standardized muscle cutting tool according to an exemplary embodiment.

[0058] In some embodiments, such as Figures 1 to 4 As shown, the cutting tool may also include a fastener 30. The connecting end 11 may be provided with a first through hole, and the end of the blade 20 may be provided with a second through hole. The fastener 30 can pass through the first through hole and the second through hole, and fix the connecting end 11 and the end of the blade 20 through its own fastening action, thereby realizing a stable assembly between the blade 20 and the hand-held part 10. Moreover, this structure facilitates the separation of the blade 20 from the connecting end 11 by disassembling the fastener 30, providing convenience for subsequent disinfection, replacement of the blade 20 and other operations.

[0059] In some embodiments, such as Figure 4 As shown, the fastener 30 includes a screw 31 and a nut 32. The screw 31 can pass through the first through hole from one side of the connecting end 11, and then through the second through hole at the end of the cutting tool 20 to the other side of the connecting end 11. The nut 32 is then screwed into the protruding end of the screw 31. Through the thread engagement force of the screw 31 and the nut 32, the connecting end 11 and the end of the cutting tool 20 are tightly fixed. Both connecting sections are provided with fasteners 30 for fixation, and the connection stability between the cutting tool 20 and the connecting end 11 is ensured by two-point fixation.

[0060] The self-locking property of the thread ensures the stability of the connection between the blade 20 and the handle 10, preventing the blade 20 from shifting due to force during cutting. It also avoids the need to install threads on the relatively soft handle 10, preventing the threads inside the handle 10 from being worn down and causing the fastener 30 to fail.

[0061] In some embodiments, such as Figure 4 As shown, the end of the fastener 30 is flush with the port surface of the first through hole, or the end of the fastener 30 is embedded in the first through hole, thereby preventing the end of the fastener 30 from protruding from the surface of the connecting end 11 to form a protruding structure, preventing the operator from being scratched by the protruding fastener 30 when holding the hand grip 10, and improving the safety and grip comfort.

[0062] In some embodiments, such as Figure 1 As shown, the cutting tool 20 includes a blade 21 that protrudes from the edge of the handle 10, such that the blade 21 is spaced at a preset distance from the connecting end 11. This preset distance can be the target thickness of the muscle tissue after cutting. By fixing the relative position of the blade 21 and the connecting end 11, this distance is locked, ensuring that each time the cutting tool cuts muscle, only muscle tissue with a thickness not exceeding this distance is allowed to be cut and separated. This allows for precise control of the cutting thickness of the muscle tissue, avoiding differences in muscle strip thickness due to variations in operating techniques, and further ensuring the consistency of muscle sample specifications.

[0063] In some embodiments, the cutting tool further includes a shim, which is detachably connected to the connecting end 11. By replacing shims of different thicknesses, the preset distance between the cutting edge 21 of the blade 20 and the connecting end 11 can be adjusted. When the shim is installed on the connecting end 11, its thickness is directly added to the connecting segment, reducing the original preset distance and thus decreasing the distance between the cutting edge 21 and the connecting end 11. Conversely, when the shim is removed or replaced with a shim of smaller thickness, the distance between the cutting edge 21 and the connecting end 11 increases accordingly. By adjusting the preset distance by replacing shims of different thicknesses, different muscle tissue cutting thickness requirements can be met, improving the tool's versatility and flexibility of use. Multiple sizes of muscle tissue can be cut without replacing the entire blade 20.

[0064] In some embodiments, the multiple blades 20 of the cutting tool are designed to enter in the same direction, and the cutting edges 21 of each blade 20 are set at the same height. Simultaneously, the force direction line of the handle 10 is coaxially arranged with the cutting direction line of the blades 20. This design significantly reduces fluid leakage caused by stretching or compression of muscle fibers during cutting, ensuring that the muscle samples remain in a consistent physiological state before measurement, and reducing the interference of sample state differences on the test results.

[0065] In some embodiments, the cutting tool 20 may be provided with a forward tilt angle relative to the connecting section. For example, the value of the forward tilt angle may be in the range of 1° to 3°. This small forward tilt angle structure allows only a portion of the blade 21 of the cutting tool 20 to contact the muscle tissue when it first comes into contact with the muscle tissue, thereby improving the pressing and cutting effect of the cutting tool, reducing the cutting force requirement in the initial stage of cutting, avoiding sample deformation due to excessive initial force, and further ensuring the integrity of the muscle sample.

[0066] In some embodiments, the standardized muscle cutting tool may include a sliding shoe or a height-limiting pad, which may be disposed on the outside of the blade 20 or on the lower edge of the support strip of the blade 20, and both the sliding shoe and the height-limiting pad are detachable and replaceable structures. When the user performs a cutting operation, the sliding shoe or height-limiting pad can slide on the surface of the cutting board on which the muscle sample is placed, and through its cooperation with the cutting board, it limits the depth of the blade 20, thereby ensuring that the cut muscle strip has an approximately uniform thickness.

[0067] The height-limiting structure, which consists of a sliding shoe or a height-limiting pad, allows different operators to obtain muscle samples of consistent thickness when using the tool, effectively improving the repeatability of sample preparation and adapting to the requirements of sample specification uniformity in experimental or testing scenarios.

[0068] In some embodiments, the handle 10, blade 20, and other components of the cutting tool can all be made of food-grade materials, and the fasteners 30 can be made of stainless steel. Both food-grade materials and stainless steel are resistant to disinfectant corrosion and can withstand the erosion of common disinfection methods such as alcohol, hydrogen peroxide, and steam, meeting the requirements for tool hygiene and corrosion resistance in laboratory sample collection and food factory production operation specifications.

[0069] In some embodiments, the outer side of the cutting tool 20 is provided with a straight bearing edge, which can be used as an external guide edge. During the cutting operation, the guide edge can cooperate with the guiding structure of the cutting board surface on which the muscle sample is placed or the external sample clamp. Through the limiting effect of the guide edge, the cutting trajectory of the cutting tool 20 can be kept straight, thereby making the edge of the cut muscle strip neat and avoiding irregular strip shape caused by cutting deviation, further improving the dimensional accuracy of the sample.

[0070] In some embodiments, the handle 10 or the blade 20 support strip of the cutting tool is provided with raised lettering indicating the size. For example, the raised lettering could be "10mm," and different sizes of tools can be distinguished by different colors. For instance, a purple handle 10 corresponds to a 10mm cutting tool. This visual design facilitates quick zoning and management of tools of different sizes in meat processing workshops or laboratories. Operators can intuitively identify tool sizes through the raised lettering and color coding. This can reduce errors in muscle strip specifications caused by misuse of tools and lower the risk of deviations in testing or experimental results.
