Description

Technical Field

[0001] This utility model relates to the field of bioscience research technology, and in particular to a special cage-changing forceps for laboratory mice. Background Technology

[0002] In life science research, laboratory animals are indispensable experimental subjects, and laboratory mice, as the most basic type of laboratory animal, constitute the vast majority in number. One of the most fundamental operations in the breeding and raising of laboratory mice is the handling and transfer of them. According to the safety operating procedures for laboratory animals, operators are not allowed to directly touch the animals with their bare hands during the handling and transfer process; therefore, general-purpose laboratory forceps are typically used to transfer the animals.

[0003] Existing cage-changing forceps have a relatively rigid structure and a smooth surface. Laboratory mice move quickly and are quite agile within their enclosures, making it difficult to grasp their tails during cage changes. Excessive force can damage the animal's tail, while insufficient force may cause the rigid tail and the forceps tip to slip. Grabbing the mouse's torso can easily damage its skin and soft tissues. Furthermore, simply grasping the tail may allow the mouse to use its tail to curl its body up and contact the top of the forceps; larger mice may even come into contact with the operator's hand, posing a risk of biting or scratching. In addition, some cage-changing forceps use glued silicone sheets to increase friction. However, during alternating alcohol disinfection and soaking, both the silicone sheets and the glue age rapidly. After a short period of use, the silicone sheets will fall off, indicating structural instability and preventing reuse. Utility Model Content

[0004] This invention provides a special cage-changing forceps for laboratory mice to solve the technical problems mentioned in the background section.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a special cage-changing forceps for laboratory mice. The special cage-changing forceps includes: a forceps body, with a triangular fixing bracket at each of the two ends of the forceps body, and a silicone component mounted on the triangular fixing bracket;

[0007] The silicone components at the two ends of the tweezers body have anti-slip textures on their opposite inner surfaces.

[0008] Preferably, the silicone component is a trapezoidal silicone component.

[0009] Preferably, the anti-slip texture is a wave pattern with alternating horizontal and vertical directions.

[0010] Preferably, the silicone component is fixedly installed at both ends of the tweezers body using a hot-melt process.

[0011] Preferably, the tweezers body is a stainless steel curved tweezers.

[0012] The significant advantages of this invention are as follows: This invention provides a dedicated cage-changing forceps for laboratory mice. Based on existing stainless steel curved forceps, this invention adds a triangular-shaped fixing bracket welded to the top of the forceps body. A silicone component is then installed and fixed to this bracket using a heat-fusion process, ensuring a secure connection between the silicone component and the forceps body and the triangular fixing bracket, preventing it from detaching due to soaking, disinfection, or repeated handling. The silicone component is made of a soft material, allowing it to be directly used to grip the torso of the laboratory mouse, preventing the mouse from rolling up its torso and injuring the operator, and also preventing damage to the mouse's skin and soft tissues. Furthermore, the inner surfaces of the silicone component at the two top ends of the forceps body are provided with anti-slip textures to prevent the mouse from struggling and accidentally escaping when gripping smooth parts of its body.

[0016] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0017] Example 1

[0018] like Figure 1As shown, this embodiment provides a special cage-changing forceps for laboratory mice. The special cage-changing forceps includes: a forceps body 1, a triangular fixing bracket 2, a silicone component 3, and anti-slip texture 4. The forceps body 1 has a triangular fixing bracket 2 at each of its two ends, and the silicone component 3 is mounted on the triangular fixing bracket 2. Anti-slip texture 4 is provided on the opposite inner sides of the silicone components 3 at the two ends of the forceps body 1. The forceps body 1 is a stainless steel curved-tip forceps. This embodiment of the special cage-changing forceps, based on existing stainless steel curved-tip forceps, has a silicone component 3 fixed at the top of the forceps body 1. This allows for direct gripping of the laboratory mouse's torso with a soft material, preventing the laboratory mouse from rolling up its torso and injuring the operator, and also preventing damage to the laboratory mouse's skin and soft tissue. Furthermore, the anti-slip texture 4 on the inner surface of the silicone component 3 prevents the laboratory mouse from struggling and accidentally escaping when gripping a smooth part of its body.

[0019] In this embodiment, the silicone component 3 is a trapezoidal silicone component, and the anti-slip texture 4 is a wave pattern with alternating horizontal and vertical directions. The trapezoidal silicone component can be used to distinguish between gripping puppies and adult mice. Specifically, the triangular fixing bracket 2 is made of the same stainless steel material as the tweezers body 1. With the combined action of the trapezoidal silicone component and the triangular fixing bracket 2, the side of the trapezoidal silicone component closer to the triangular fixing bracket 2 can be used to grip large, heavy adult mice, providing greater holding force; the other side of the trapezoidal silicone component closer to the triangular fixing bracket 2 is soft enough to protect the puppies during gripping, preventing injury. The anti-slip texture 4, with alternating horizontal and vertical directions, is set on the opposite inner surfaces of the two top silicone components of the tweezers body 1, effectively increasing the friction with the animal contact surface and preventing the mice from escaping.

[0020] In this embodiment, the silicone component 3 is fixedly installed at both ends of the tweezers body 1 using a hot-melt processing technology. Fixing the silicone component 3 to the top of the triangular support 2 and the tweezers body 1 using a hot-melt forming process greatly enhances the structural strength of the silicone component 3, while also ensuring that the silicone component 3 is firmly fixed to the top of the tweezers body 1 and is not easily detached. This makes the special cage-changing tweezers of this embodiment less prone to loosening or falling off during repeated sterilization, gripping, and other experiments.

[0021] This embodiment provides a dedicated cage-changing forceps for laboratory mice. Based on existing stainless steel curved forceps, this dedicated forceps has a triangular-shaped fixing bracket welded to the top of the forceps body. A silicone component is then installed and fixed to the triangular fixing bracket using a heat-fusion process, ensuring a secure connection between the silicone component and the forceps body and the triangular fixing bracket, preventing it from falling off due to soaking, disinfection, or repeated handling. The silicone component is made of a soft material and can be directly used to grip the torso of the laboratory mouse, preventing the mouse from rolling up its torso and injuring the operator, and also preventing damage to the mouse's skin and soft tissue. Furthermore, the inner surfaces of the silicone component at the two top ends of the forceps body have anti-slip textures to prevent the mouse from struggling and accidentally escaping when gripping smooth parts of its body.

[0022] The working principle of this utility model is as follows: a triangular fixing bracket 2 is welded onto the main body 1 of the tweezers, and a silicone component 3 is fixedly installed on the triangular fixing bracket 2 by hot melting process. The inner surface of the silicone component 3 is provided with anti-slip texture 4, thereby making a complete special cage changing tweezers for laboratory mice. This special cage changing tweezers can be used for laboratory mice in different growth stages, can firmly hold the laboratory mice, and will not cause harm to the operator or damage to the epidermis and soft tissue of the laboratory mice.

[0023] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
