Description

Anti-freezing forceps convenient for taking pipe

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an anti-freezing forceps convenient for taking a tube.

Background

Straws or cryopreservation tubes are containers mainly used for preserving biological samples such as animal and plant tissues or embryos, and are generally preserved in a low-temperature medium, for example, liquid nitrogen. Therefore, after the operator takes out the straw or the cryopreserved pipe from the low-temperature medium through a tool, the pipe cap of the cryopreserved pipe is generally removed by using forceps, so that the risk of frostbite of the operator can be avoided. Because the cryopreserved pipe is generally thinner relatively, and the material adopts soft materials to support simultaneously, for this reason operating personnel when adopting tweezers commonly used to carry out centre gripping pipe cap, the exposed core of tweezers takes place relative displacement with the pipe cap easily, leads to the clamping-force not enough and can't open the pipe cap.

In view of the above situation, chinese patent CN 201520222429.5-a pair of tweezers suitable for embryo freezing discloses a pair of tweezers including a tweezers handle and tweezers arms connected with the tweezers handle as a whole and symmetrically arranged, a tweezers head connected to an end of the tweezers arm, and a plastic foam arranged on an inner side of the tweezers head. Therefore, when the straw is taken by adopting the straw taking forceps, the contact area between the forceps and the straw is large, the stress of the unit area of the straw is small, the surface of the plastic foam is rough, the forceps are not easy to slip, and meanwhile, the plastic foam is soft, so that the straw is prevented from slipping or being pinched. However, in this patent the overall forceps holding force is primarily the force exerted by the operator's finger on the forceps arm, for which reason the force exerted by the forceps arm on the straw is directly equal to the force exerted by the operator's finger. In the actual use process, the fingers of an operator generally directly press the middle part of the forceps arm or one end close to the handle, so that one end of the forceps arm close to the forceps head can generate a deformation, when the deformation of the forceps arm is overlarge, the two forceps arms are positioned at the finger operation point and are jointed, at the moment, even if the operator increases the application force, the acting force of the forceps arm cannot be increased, and the actual operation effect is influenced. The deformation amount of the forceps arm is related to the acting force applied by an operator and the material of the forceps arm, so that the forceps head and the tube cap of the straw are easy to slide when the acting force is not high or the forceps arm is excessively deformed due to flexibility. Particularly, when the forceps arm is made of materials or is too long, the forceps head and the straw cap of the straw are easy to slide. Therefore, in some practical operations, if the pipe cap is connected with the straw too tightly, the operator needs to adjust the position of the finger closer to the forceps head to increase the acting force of the forceps head, increase the friction and reduce the problem that the applied force cannot be transmitted due to the deformation of the forceps arm. Although this increases the grip of the forceps head, frostbite is likely to occur due to the close proximity of the operator's fingers to the forceps head. And the operator needs to increase the application force when opening, which leads to increased operation difficulty and high labor intensity.
