Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, and particularly discloses a dripping forceps. BACKGROUND

[0002] In medical operations or laboratory operations, dripping forceps are a commonly used tool, mainly used for accurately dripping liquid to a specified position. Dripping forceps play an important role in various application scenarios, such as being used for accurately dripping reagents in microsurgical operations, being used for adding culture medium in cell culture experiments, etc. However, traditional dripping forceps have some problems in the process of use, which not only affect the accuracy and efficiency of dripping, but also may cause inconvenience in operation and even failure.

[0003] Problems in the Prior Art

[0004] Thermal damage and "mushroom effect":

[0005] When used in a high-temperature environment, the tip of the traditional dripping forceps is prone to thermal damage, resulting in the so-called "mushroom effect". The so-called "mushroom effect" refers to the expansion and deformation of the tip due to heat, which not only affects the accuracy of the tip, but also may cause the liquid to be unable to be accurately dripped to the specified position when dripping.

[0006] The "mushroom effect" also shortens the service life of the tip, increasing the maintenance cost.

[0007] Uneven dripping:

[0008] The traditional dripping forceps are prone to uneven dripping when dripping liquid, especially in the case of needing to accurately control the amount of liquid, such unevenness will cause deviation of experimental results.

[0009] The problem of uneven dripping may be caused by unreasonable design of the dripping hole or instability of the liquid delivery system.

[0010] Unsuitable position of the dripping hole:

[0011] Unreasonable design of the position of the dripping hole will directly affect the accuracy of dripping. If the position of the dripping hole is not appropriate, it may cause the liquid to be dripped to the wrong position, thereby affecting the results of the operation or experiment.

[0012] Unsuitable position of the dripping hole may also cause the liquid to splash during the dripping process, causing waste or pollution.

[0013] Inconvenient operation:

[0014] The traditional dripping forceps may have certain limitations in design, causing inconvenience in the process of use. For example, the design of the handle may not be humanized enough, and it is not comfortable to hold, and it is easy to be tired after a long time of use.

[0015] If the connecting part of the tweezers head and the tweezers tip is unstable, dislocation may occur during use, affecting the accuracy of operation. Content of the utility model

[0092] Water pipe 6 and cavity design:

[0093] Water pipe 6 setting:

[0094] The tweezers head 3 is provided with a water pipe 6, which is used for transporting liquid.

[0095] The design of the water pipe 6 makes the liquid enter the tweezers head 3 from the outside and be transmitted to the water outlet hole 5 through the internal cavity system.

[0096] Cavity system:

[0097] The tweezers handle 1, the positioning column 2 and the tweezers tip 4 are all provided with cavities, which cooperate with each other to transport liquid to the dripping hole.
