Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of micro tweezers, and more specifically, it relates to a micro tweezer for preventing jitter and clamping injury of mouse bone marrow. Background Art
[0002] Micro tweezers are one of the commonly used microsurgical instruments, which can be used to extract, separate fine tissues and pick up and tie sutures. The tip of the micro tweezers is sharp but not too sharp, the edges have no sharp corners, and they fit well, and can firmly hold fine objects. In animal experiments, it is often necessary to use micro tweezers to hold the mouse spinal cord. However, such micro tweezers have the following problems: If you want to firmly hold the spinal cord, etc., you need to continuously use the index finger and thumb together for a long time, which is easy to fatigue. After fatigue, hand tremors are likely to occur, and the clamping is unstable, which will cause different degrees of damage to the spinal cord and affect the results of animal experiments. In view of this, the inventor of the present invention proposes a micro tweezer for preventing jitter and clamping injury of mouse bone marrow. Content of the Utility Model
[0003] The purpose of the utility model is to provide a micro tweezer for preventing jitter and clamping injury of mouse bone marrow to solve the above problems.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions: A micro tweezer for preventing jitter and clamping injury of mouse bone marrow, including a tweezer clip and a tweezer head, the tweezer clip is fixedly connected to the tweezer head, a chute is opened inside the tweezer clip, a pulley is slidably connected to the chute, and a spring is fixedly connected to one end of the pulley close to the inside.
[0005] The utility model is further provided as: Scale lines are provided on the outer surface of the tweezer clip at the corresponding positions of the chute.
[0006] In summary, the utility model has the following beneficial effects: The utility model uses fingers to control and fix the pulley, and uses the elastic force and tensile force of the spring to control the bending degree of the two tweezer clips, preventing the mouse spinal cord from being damaged to different degrees due to hand tremors during clamping, and avoiding affecting the experimental results.

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0012] Embodiment:
[0013] A micro forceps for clamping mouse bone marrow with anti-shaking, as Figure 1 、 Figure 2 and Figure 3 shown, includes a forceps clip 1 and a forceps tip 2. The forceps clip 1 is fixedly connected to the forceps tip 2. A chute 6 is opened inside the forceps clip 1. A pulley 3 is slidably connected to the chute 6. One end of the pulley 3 close to the inner side is fixedly connected to a spring 4.
[0014] In this embodiment, scale lines 5 are provided on the outer surface of the forceps clip 1 at the corresponding positions of the chute 6.
[0015] Working principle and usage process:
[0016] During use, first adjust the pulley 3 to a suitable position according to the scale lines 5. Then fix the pulley 3 with the thumb and index finger. Subsequently, the thumb and index finger are used to forcefully squeeze the forceps clip 1 inward. The forceps clip 1 is fixedly connected to the forceps tip 2, and the forceps tip 2 moves closer inward to clamp the mouse spinal cord. During this process, the elasticity and tensile force of the spring 4 are utilized to control the bending degree of the two forceps clips 1, preventing the mouse spinal cord from being damaged to varying degrees due to hand shaking during clamping and avoiding affecting the experimental results.
[0017] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
