Technical Field
[0001] This utility model relates to the field of clamping tool technology, and in particular to a cell slide forceps. Background Technology
[0002] Tweezers are a commonly used auxiliary tool that is widely used in the medical industry because it can accurately and conveniently grasp objects.
[0003] In existing technologies, tweezers generally consist of a handle and a head. Existing tweezers include a head and a corresponding fixed end. After long-term use, the head is the most easily damaged part. Once the head is damaged, the entire tweezers are scrapped, wasting materials. In addition, since cell slides with a diameter ≤15mm need to be taken from the bottom of a 24-well plate with a depth of 17-18mm, existing tweezers require a tool with a small hook at the tip to hook one side of the cell slide upwards before the tweezers can be used to pick it up. This is inconvenient and the force cannot be controlled properly, which can easily lead to the breakage of the cell slide.
[0004] To address the aforementioned problems, this invention provides a cell slab tweezers to solve the technical issues of inconvenient tweezers head replacement and complex cell slab handling in the prior art. Utility Model Content
[0005] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a cell slide forceps that effectively solves the technical problems of inconvenient forceps head replacement and complex cell slide handling operations.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] This utility model provides a cell slide forceps, including two elastic forceps handles, two forceps heads, and a connector. One end of the two elastic forceps handles is fixed together to form a fixed end, and the other end is spaced apart to form a free end. Each of the two forceps heads includes a forceps tip and a forceps tail end. The forceps tail end is detachably connected to the free end of the elastic forceps handle through the connector. The forceps tip bends along the force direction of either elastic forceps handle, and the bending direction of the two forceps tips is the same.
[0008] Furthermore, the free ends of the two elastic tweezer handles are provided with dovetail grooves, and the dovetail grooves extend from the free ends to the fixed ends. The tail ends of the two tweezer heads are provided with locking blocks corresponding to the dovetail grooves. The free ends of the elastic tweezer handles are also provided with threaded holes that penetrate the free ends. The connecting piece is a bolt with a corresponding threaded hole specification. After the locking blocks are installed in place, the locking blocks are locked to the dovetail grooves by changing the tightening torque of the bolts.
[0009] Furthermore, the two tweezers are forward-facing tweezers. After the tweezers are installed to the elastic tweezers handle via the connector, the tweezers close when the elastic tweezers handle is squeezed, and open when the elastic tweezers handle is released.
[0010] Furthermore, the two tweezers are reverse-oriented tweezers. After the tweezers are installed to the elastic tweezers handle via the connector, the tweezers open when the elastic tweezers handle is squeezed, and close when the elastic tweezers handle is released.
[0011] Furthermore, the elastic tweezers handle is also provided with a guiding device, which includes a guide plate disposed on the inner side of one of the elastic tweezers handles and a guide groove formed on the other elastic tweezers handle. The guide groove is used to insert the guide plate, and the extension direction of the guide plate is the same as the force direction of the elastic tweezers handle in which it is located.
[0012] Furthermore, two guide plates are provided along the length direction of the elastic tweezer handle, and the two guide plates are parallel to each other. The other elastic tweezer handle is provided with two guide grooves corresponding to the guide plates.
[0013] Furthermore, the guide plate is arc-shaped and bends towards the fixed end, and the arc angle is greater than the maximum opening angle of the elastic tweezer handle.
[0014] Furthermore, the opposing surfaces of the tweezers tip have textured surfaces.
[0015] Furthermore, the textured surfaces at the tips of the two tweezers can engage with each other.
[0016] Furthermore, the outer end faces of the two elastic tweezer handles are respectively formed with anti-slip textures.
[0017] Compared with the prior art, the cell smear forceps provided by this utility model have the following beneficial effects:
[0018] First, this utility model separates the elastic tweezer handle and the tweezer head, and uses a connector to connect the elastic tweezer handle and the tweezer head. When the tweezer head needs to be replaced, the tweezer head can be directly removed from the free end of the elastic tweezer handle, and a suitable tweezer head can be installed on the free end of the elastic tweezer handle. The operation is simple and quick, and the replacement is convenient.
[0019] Secondly, the tip of the tweezers of this invention bends along the direction of force on the elastic tweezers handle. Therefore, when picking up cell slabs located at the bottom of the well plate, the bent tip of the tweezers can be used to hook one side of the cell slab upwards and then pick it up directly without the need for auxiliary devices, making the operation simple.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] This embodiment relates to a cell smear forceps, with an exemplary structure as shown below. Figure 1 and Figure 2 As shown.
[0029] Overall, the cell smear forceps includes two flexible handles 1, two forceps heads 2, and a connector. One end of each flexible handle 1 is fixed together to form a fixed end, while the other ends are spaced apart to form free ends. Each forceps head 2 includes a tip and a tail end. The tail end of the forceps head is detachably connected to the free end of the flexible handle 1 via the connector. The tip of the forceps head bends along the direction of force applied to either flexible handle, and the bending direction of both tips is consistent. (See attached instruction manual.) Figure 1 For example, the bending direction of the tip of the tweezers is the same as the direction of force on the elastic tweezer handle below;
[0030] In this embodiment, by separating the elastic forceps handle 1 and the forceps head 2 and connecting them with a connector, when the forceps head 2 needs to be replaced, it can be directly removed from the free end of the elastic forceps handle 1, and a suitable forceps head 2 can be installed on the free end of the elastic forceps handle 1. The operation is simple, quick, and convenient. In addition, the tips of the two forceps heads 2 are bent along the force direction of one of the elastic forceps handles, so the bending direction of the tips of the two forceps heads is consistent. When picking up the cell spreader located at the bottom of the well plate, the bent tip of one of the forceps heads 2 is used to first hook one side of the cell spreader upward. Then the operator changes the orientation of the tip of the forceps head and places the tip of the other forceps head on the other side of the cell spreader. At this time, the cell spreader is located between the two forceps heads 2, and then the cell spreader is picked up to remove it from the bottom of the well plate. This process does not require the cooperation of auxiliary devices, making the operation simple and convenient. At the same time, the absence of auxiliary devices also reduces the risk of cell spreader contamination.
[0031] In this embodiment, the free ends of the two elastic tweezer handles 1 are provided with dovetail grooves, which extend from the free ends towards the fixed ends. The tail ends of the two tweezer heads are provided with locking blocks corresponding to the dovetail grooves. The free ends of the elastic tweezer handles are also provided with threaded holes penetrating the free ends. The connecting component is a bolt 3 with a corresponding threaded hole specification. After the locking blocks are installed in place, the locking blocks are locked to the dovetail grooves by changing the tightening torque of the bolts 3. When it is necessary to remove the tweezer head 2 from the free end, one of the bolts 3 is loosened first, and then the locking block at the tail end of the corresponding tweezer head 2 is removed from the dovetail groove. The other tweezers head 2 is removed in the same way, thus separating the tweezers head 2 from the elastic tweezers handle 1. When it is necessary to install the tweezers head 2 onto the elastic tweezers handle 1, first insert the locking block of one of the tweezers head 2 into the free end of the corresponding elastic tweezers handle 1. After the insertion distance is in place, install the bolt 3 into the threaded hole of the free end and tighten it until the tweezers head 2 cannot be detached by itself. After one tweezers head 2 is installed in place, install the other tweezers head 2 in the same way until both tweezers head 2 are installed, thus completing the installation of the tweezers head 2.
[0032] See attached document Figure 1 As shown, in this embodiment, the two forceps heads 2 are forward-facing forceps heads. After the forceps heads are installed to the elastic forceps handle 1 via the connector, the forceps heads 2 close when the elastic forceps handle 1 is squeezed; when the elastic forceps handle 1 is released, the forceps heads 2 open. Because the default state of forward-facing forceps is naturally open, it is suitable for scenarios that require frequent picking. When operators need to pick up multiple sets of cell slides in a short period of time, using cell slide forceps equipped with forward-facing forceps heads can effectively improve work efficiency.
[0033] See attached document Figure 2As shown, in this embodiment, the two forceps heads 2 are reverse forceps heads. After the forceps heads 2 are installed to the elastic forceps handle 1 through the connector, the forceps heads 2 open when the elastic forceps handle 1 is squeezed; the forceps heads 2 close when the elastic forceps handle 1 is released. Because the default state of the reverse forceps is naturally closed, it is suitable for scenarios that require stable fixation. When the operator needs to manually hold and transfer cell slides, using cell slide forceps with reverse forceps heads can reduce the muscle soreness caused by prolonged squeezing of the forceps and reduce the risk of cell slides falling off due to unstable clamping force.
[0034] In this embodiment, the elastic tweezer handle 1 is also provided with a guiding device. The guiding device includes a guide plate 4 disposed on the inner side of any elastic tweezer handle and a guide groove 5 opened on another elastic tweezer handle. The guide groove 5 is used to insert the guide plate 4. The extension direction of the guide plate 4 is the same as the force direction of the elastic tweezer handle 1 on which the guide plate 4 is located. The opening shape of the guide groove 5 matches the shape of the guide plate 4, and the extension direction of the guide plate 4 is the same as the force direction of the elastic tweezer handle 1 on which it is located. Therefore, during the process of pinching the elastic tweezer handle 1, the guide plate 4 can restrict the clamping or opening direction of the elastic tweezer handle 1, thereby stabilizing the path of the tweezer tip and reducing the risk of misalignment of the tweezer tip 2.
[0035] In this embodiment, two guide plates 4 are provided and are arranged in parallel and staggered. Two guide grooves 5 corresponding to the guide plates 4 are provided on another elastic tweezer handle 1. The guide plates 4 are arc-shaped and bend towards the fixed end. The arc angle is greater than the maximum opening angle of the elastic tweezer handle 1. The center of the arc-shaped guide plate 4 coincides with the fixed end of the elastic tweezer handle 1, and the arc angle of the guide plate 4, that is, the degree of the central angle corresponding to the arc, is greater than the maximum opening angle of the elastic tweezer handle 1. Therefore, during the guiding process, the lateral deviation problem of the elastic tweezer handle 1 can be completely reduced. At the same time, the method of setting two guide plates 4 and guide grooves 4 can further improve the guiding accuracy.
[0036] In this embodiment, the opposing surfaces of the tweezer tips have textured surfaces, and the textured surfaces of the two tweezer tips can mesh with each other; at the same time, the outer end faces of the two elastic tweezer handles 1 are respectively formed with anti-slip textures, which can not only improve the meshing friction of the tweezer tips and improve the clamping stability, but also reduce the risk of slipping out of the hand.
[0037] See attached document Figure 3 and attached Figure 4 As shown, the tip of the forceps can be flat to increase the applicability of the cell slide forceps.
[0038] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
