Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a pathological material collection knife handle. Background Art
[0002] Pathology is a medical science that uses natural science methods to study the causes, pathogenesis, morphological structure, function and metabolism of diseases, reveal the laws of disease occurrence and development, and thus clarify the nature of diseases. Pathology is not only a basic medical discipline, but also a highly practical and clinical discipline. In the process of pathology research, it is often necessary to use a sampling knife to cut pathological tissues and extract samples.
[0003] There are many types of knife handles for tissue pathology sampling. However, the existing tissue pathology sampling knife handles basically rely on an elastic element between two iron sheets to clamp the blade. This leads to two problems: (1) The blade is difficult to install and may fly out and injure others if not installed. It is especially easy to accidentally injure the face and cause disfigurement; (2) This type of knife handle will become loose after a short period of use and cannot be restored or maintained, resulting in the blade constantly falling off during the sampling process, affecting the sampling speed and accuracy.
[0004] The utility model aims at solving the above problems and provides a pathological specimen collection knife handle. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The utility model can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0033] like Figure 1-7The pathological specimen collection handle shown includes a first clamping arm 2, a second clamping arm 3 and a limiting structure 4; the first clamping arm 2 and the second clamping arm 3 are crossed in a clamp-like manner, and the first clamping arm 2 and the second clamping arm 3 are rotatably connected via a rotating shaft 24; one end of the limiting structure 4 is adapted to the first clamping arm 2, and the other end is detachably connected to the second clamping arm 3.
[0034] The first clamping arm 2 and the second clamping arm 3 of the clamp type are opened to facilitate blade replacement. The first clamping arm 2 and the second clamping arm 3 of the clamp type can firmly clamp the blade after closing, and the limiting structure 4 limits the state of the first clamping arm 2 and the second clamping arm 3 after closing, preventing the blade from loosening due to the opening of the first clamping arm 2 and the second clamping arm 3. The problem of the existing material collection handle being difficult to install the blade and the blade being easy to fall off after loosening is solved.
[0035] Furthermore, a handle 1 is provided on the side wall of the first clamping arm 2, and the handle 1 is fixedly connected to the first clamping arm 2. When the blade is clamped between the first clamping arm 2 and the second clamping arm 3, the handle 1 can be held to drive the blade to cut the pathological tissue to extract the sample.
[0036] The first clamping arm 2 includes a first clamping end 21 and a first limiting end 22; there is an angle less than 180° between the first clamping end 21 and the first limiting end 22; a first through hole adapted to the rotating shaft 24 is provided between the first clamping end 21 and the first limiting end 22. The first clamping end 21 contacts the blade and presses the blade against the side wall of the second clamping arm 3, and the friction force is used to limit the position of the blade.
[0037] Furthermore, a first anti-slip structure is provided on one side of the first clamping end 21 facing the second clamping arm 3 to increase the friction between the first clamping end 21 and the blade to prevent the blade from falling off.
[0038] Preferably, the first anti-slip structure is a first rubber dot matrix, which is composed of a plurality of rubber dots arranged in a matrix.
[0039] Alternatively, the first anti-slip structure is a first anti-slip pattern.
[0040] In some embodiments of the present application, a scale is provided on a side of the first clamping end 21 away from the second clamping arm 3 .
[0041] like Figure 3-4 As shown, a limiting groove 23 is provided inside the first limiting end 22. Figure 1-2 It can be seen that the limiting groove 23 is adapted to the limiting structure 4. When in use, the limiting structure 4 is used to limit the positional relationship between the first limiting end 22 and the second clamping arm 3, thereby locking the positional relationship between the first clamping end 21 and the second clamping arm 3 to prevent the blade from falling off between the first clamping end 21 and the second clamping arm 3.
[0042] Preferably, more than two limiting grooves 23 are provided inside the first limiting end 22; the limiting grooves 23 are evenly arrayed inside the first limiting end 22. Multiple limiting grooves 23 can be installed with multiple limiting structures 4 to enhance the stability between the first clamping arm 2 and the second clamping arm 3.
[0043] In some embodiments of the present application, a reinforcing structure is provided around the limiting groove 23 to enhance the strength of the limiting groove 23 and prevent the limiting groove 23 from deforming under the pulling of the limiting structure 4, thereby reducing the limiting effect of the limiting structure 4.
[0044] like Figure 1-6 As shown, the second clamping arm 3 includes a second clamping end 31 and a second limiting end 32; there is an angle less than 180° between the second clamping end 31 and the second limiting end 32; a second through hole adapted to the rotating shaft 24 is provided between the second clamping end 31 and the second limiting end 32. The second clamping end 31 contacts the blade and presses the blade against the side wall of the first clamping end 21, and the friction force is applied to limit the position of the blade.
[0045] Furthermore, a second anti-slip structure is provided on a side of the second clamping end 31 facing the second clamping arm 3 to increase the friction between the second clamping end 31 and the blade to prevent the blade from falling off.
[0046] Preferably, the second anti-slip structure is a second rubber dot matrix, which is composed of a plurality of rubber dots arranged in a matrix.
[0047] Alternatively, the second anti-slip structure is a second anti-slip pattern.
[0048] A limiting hole 33 is provided inside the second limiting end 32; the limiting hole 33 is adapted to the limiting structure 4. The limiting hole 33 is adapted to the limiting structure 4. When in use, the limiting structure 4 is used to limit the positional relationship between the first limiting end 22 and the second limiting end 32, thereby locking the positional relationship between the first clamping end 21 and the second clamping end 31, and preventing the blade from falling off between the first clamping end 21 and the second clamping end 31.
[0049] The second limiting end 32 is provided with more than two limiting holes 33 inside; the limiting holes 33 are evenly arrayed inside the second limiting end 32. The number of the limiting holes 33 is the same as the limiting grooves 23, and the positions of the limiting holes 33 correspond to the limiting grooves 23 one by one.
[0050] like Figure 1-7As shown, the limiting structure 4 includes a control end 41, an adjustment column 42 and a limiting block 43; the control end 41 and the limiting block 43 are respectively located at the two ends of the adjustment column 42; the cross-sectional areas of the control end 41 and the limiting block 43 are both larger than the cross-sectional area of the adjustment column 42. During use, one end of the adjustment column 42 passes through the limiting hole 33 and is connected to the control end 41, and the other end passes through the limiting groove 23 and is connected to the limiting block 43. The control end 41 and the limiting block 43 are firmly clamped on both sides of the first limiting end 22 and the second limiting end 32, and the first limiting end 22 and the second limiting end 32 are squeezed inwardly. Since the first clamping arm 2 and the second clamping arm 3 are clamp-type structures, when the first limiting end 22 and the second limiting end 32 are squeezed inwardly, the first clamping end 21 and the second clamping end 31 will squeeze the blade inwardly, and the friction force is used to limit the position of the blade.
[0051] The width of the limiting block 43 is greater than the width of the limiting groove 23 , and the limiting block 43 cannot pass through the limiting groove 23 .
[0052] Specifically, the outer wall of the adjusting column 42 is provided with threads; the limiting hole 33 is a threaded hole. The adjusting column 42 is threadedly connected to the limiting hole 33. The adjusting column 42 is threadedly connected to the limiting hole 33 and the limiting block 43 is used to squeeze the first limiting end 22 and the second limiting end 32 inward, thereby increasing the applicable scope of the limiting structure 4. Even if the first limiting end 22 or the second limiting end 32 is slightly deformed, the limiting structure 4 can continue to be used for limiting.
[0053] The clamping principle of this embodiment is as follows: the first clamping arm 2 and the second clamping arm 3 are mutually crossed clamp-type structures. When the first limit end 22 and the second limit end 32 are squeezed inward, the first clamping end 21 and the second clamping end 31 will squeeze the blade inward, and the friction force is used to limit the position of the blade.
[0054] The limit block 43 cannot pass through the limit groove 23. During the continuous rotation of the adjustment column 42, the limit block 43 gradually moves toward the second limit end 32, driving the first clamping end 21 and the second clamping end 31 to gradually tighten until the blade is firmly fixed between the first clamping end 21 and the second clamping end 31.

Those skilled in the art can easily understand other advantages and effects of the utility model from the contents disclosed in this specification. The utility model can also be implemented or applied through other different specific implementation methods.
