Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a pair of specimen picking tweezers. Background Art

[0002] During the external sampling process in the pathology department, small biopsy specimens need to be processed. Such specimens usually appear as cylindrical tissues or shredded tissues with a length ranging from several millimeters to several centimeters and a diameter of 1-4 mm, soaked in sufficient protective fluid such as formalin.

[0003] In current practical working scenarios, most of the forceps used in operating rooms are universal forceps, and there is a lack of specially designed forceps. Since conventional forceps have narrow tips, the area that can be used to clamp specimens is very small. Specimens often flow through the gaps between the forceps as the liquid flows, making it difficult to clamp specimens, prolonging the time required to obtain specimens, and reducing the efficiency of obtaining specimens. At the same time, existing forceps are prone to causing small biopsy specimens to be squeezed, deformed, and damaged.

[0004] Therefore, there is an urgent need for a kind of specimen picking forceps with professional and targeted design, which can reduce the difficulty of picking up such specimens, reduce the sampling time, improve the sampling efficiency, and reduce the risk of squeezing tissue.

[0043] In order to enable those skilled in the art to use the contents of the present invention, the following exemplary embodiments may be given in combination with specific application scenarios, specific systems, parameters of devices and components, and specific connection methods. However, for those skilled in the art, these embodiments are only examples, and the general principles defined herein may be applied to other embodiments and application scenarios without departing from the spirit and scope of the present invention.

[0044] According to an exemplary embodiment of the present invention: Figure 1-9As shown, a specimen picking forceps includes: a left forceps arm 10 and a right forceps arm 20; the left forceps arm 10 includes: a left connecting section 11, a left clamping section 12, a left turning section 13 and a left head 14; the right forceps arm 20 includes: a right connecting section 21, a right clamping section 22, a right turning section 23 and a right head 24.

[0045] like Figure 1 As shown, the left connecting section 11 and the right connecting section 21 are fixedly connected together or integrally formed. Figure 1 The schematic left connecting section 11 and the right connecting section 21 are fixed together by two rivets. The left connecting section 11 and the right connecting section 21 can also be formed in one piece, that is, the left tweezer arm 10 and the right tweezer arm 20 are formed by bending the same metal plate. Schematically, the left tweezer arm 10 and the right tweezer arm 20 are both formed with anti-slip grooves.

[0046] like Figure 1 As shown in FIG. 2 , the left head 14 forms a left concave space, and the left head 14 is provided with a plurality of left through holes 17. Figure 3 , 4, the right head 24 forms a right concave space, and the right head 24 is provided with at least one right through hole 27;

[0047] The tweezers of the utility model can be switched between an open state and a closed state. When picking up a specimen, by pressing the left clamping section 12 and the right clamping section 22, the left head 14 and the right head 24 form a closed space for accommodating the specimen. After releasing the left clamping section 12 and the right clamping section 22, it returns to the loosened state.

[0048] like Figure 2 4, the left forceps arm 10 is formed by bending a metal plate, and the right forceps arm 20 is formed by bending a metal plate. The left head 14 and the right head 24 are both shovel-shaped structures, and the closed space is roughly a cone. Its maximum diameter is 1-3cm.

[0049] like Figure 1-9 As shown, the left connecting section 11 is roughly a plate-like structure, and the left connecting section 11 includes a left connecting surface, and the left connecting surface is roughly parallel to the left contact surface. The right connecting section 21 is roughly a plate-like structure, and the right connecting section 21 includes a right connecting surface, and the right connecting surface is roughly parallel to the right contact surface. The left head 14 includes a left contact surface, and the right head 24 includes a right contact surface, and the left contact surface is roughly parallel to the right contact surface. Through the above parallel arrangement, it is ensured that when the left head 14 and the right head 24 are closed, the left contact surface and the right contact surface are flatly matched to prevent the specimen from flowing out of the gap.

[0050] like Figure 1As shown in FIG. 3 , the left clamping section 12 is generally a plate-like structure, and a first angle is formed between the left connecting section 11 and the left clamping section 12; the left turning section 13 is used to shift the left head 14 toward the closed position of the forceps. The right clamping section 22 is generally a plate-like structure, and a second angle is formed between the right connecting section 21 and the right clamping section 22; the right turning section 23 is used to shift the right head 24 toward the closed position of the forceps. The above arrangement only requires the left clamping section 12 and the right clamping section 22 to return to an angle smaller than the first angle and the second angle, so as to complete the closure between the left head 14 and the right head 24, which is convenient for medical staff to operate with less effort.

[0051] like Figure 2 As shown in FIG. 4 , the left turning section 13 is formed with a left turning groove 15, which is connected to the left concave space; the right turning section 23 is formed with a right turning groove 25, which is connected to the right concave space. When clamping, the liquid can flow out quickly through the left turning groove 15 and the right turning groove 25.

[0052] like Figure 2 As shown in FIG. 4 , at least one left bottom groove 18 is formed at the bottom of the left concave space; at least one right bottom groove 28 is formed at the bottom of the right concave space. At least one left groove 19 is formed at the side of the left concave space; at least one right groove 29 is formed at the side of the right concave space. When clamping the specimen, the liquid such as formalin can be easily discharged from the surface through the left and right through holes 27, and at the same time, it can be easily discharged from the bottom through the left bottom groove 18 and the right bottom groove 28. And through the arrangement of the left groove 19 and the right groove 29, the liquid can be easily discharged even when the specimen is taken from an inclined direction. Preferably, when the left head 14 and the right head 24 are closed, the left bottom groove 18 and the right bottom groove 28 together form a bottom connecting groove, and the left groove 19 and the right groove 29 together form a side connecting groove.

[0053] like Figure 10-12 FIG. 2 is a perspective view of a right forceps arm 20 of another exemplary embodiment of the present invention. Since the right forceps arm 20 of the present invention has the same structure as the left forceps arm 10, only the structure of the right forceps arm 20 is shown. The difference between this embodiment and the previous embodiment is that: Fig.12 As shown, at least part of the left bottom groove 18 is connected to the left side groove 19, and at least part of the right bottom groove 28 is connected to the right side groove 29. Fig.12 As shown, there are 3 schematic left bottom grooves 18 and right bottom grooves 28, 3 left bottom grooves 19 and 3 right bottom grooves 29, wherein the left bottom grooves 18 on both sides of the lower part are connected to the left bottom groove 19; wherein the right bottom grooves 28 on both sides of the lower part are connected to the right bottom groove 29. The above connection enables the liquid to be removed quickly even when the tweezers are in a tilted state.

[0054] like Figure 1-12 As shown, in specific medical use, the specimen picking forceps of the utility model have a total length of 18-30 cm, and can be made of stainless steel, consisting of two connected stainless steel sheets. When the forceps are closed, they are hollow cones with a length of 1-1.5 cm.

[0055] When the utility model is clamped, the front view is a hollow cone, and the length of the left head 14 and the right head 24 in the vertical direction is 1-1.5 cm. When placed naturally, the left head 14 and the right head 24 are separated, and the picking part on each side is a shovel-shaped structure, and the widest part is about 1-2 cm, preferably 1 cm.

[0056] The left through hole 17 and the right through hole 27 are distributed on the arc surface of the left concave part 16 and the right concave part 26, which are small holes with a diameter of 0.05-0.2 cm, preferably 0.08 cm. The inner side of the lower tip of the left concave part 16 and the right concave part 26 is provided with a left bottom groove 18 and a right bottom groove 28 distributed along the vertical direction, so that the liquid in the cone-shaped structure can flow out when clamped. The left concave part 16 and the right concave part 26 are provided with a left groove 19 and a right groove 29 distributed along the horizontal direction on both sides, so that the liquid in the cone-shaped structure can flow out when clamped.

[0057] The specimen picking forceps of the utility model can form a hollow cone when clamped, and the small specimen is surrounded in the cone, which can avoid the slippage phenomenon that often occurs when ordinary forceps clamp small specimens, thereby reducing the difficulty of obtaining small biopsy specimens, reducing the time of obtaining specimens, and improving the efficiency of obtaining specimens. At the same time, the small holes on the arc surface are conducive to the outflow of formalin liquid in the cone when clamped, and the left bottom groove 18 and the right bottom groove 28 on the inner side of the cone tip and the left groove 19 and the right groove 29 on the side of the cone are all diversion structures, which can effectively reduce the amount of formalin liquid remaining in the cone after picking up.

[0058] The left and right in the present invention are only for distinction and do not represent limitation. In fact, the left and right references mentioned above can be interchangeable; the left and right appearing in the present invention can also be replaced by the first and the second respectively, all within the protection scope of the present invention.

[0059] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes and combinations of elements may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
