Problems solved by technology

The current sampling device is usually ordinary surgical tweezers. This kind of surgical tweezers does not have a blade, so sampling is very difficult, and it is easy to slip during the clamping process, resulting in loss of specimens, and it cannot be guaranteed that the volume of each sample is the same, which is not good for diagnosis. Therefore it is necessary to improve

Embodiment Construction

[0010] Attached below figure 1 An embodiment of the present invention is described.

[0011] The small tissue sampling knife device has a body 5, the body 5 is tubular, one end of the body 5 is formed with a cutter head, and the other end is inserted into a piston 6, and the cutter head is composed of a blade 1, a blade 2 and a blade 3, and the blade 1 and the blade 2 is a V-shaped included angle, the blade 3 is arc-shaped and is closed and connected with the blade 1 and the blade 2, the piston 6 is inserted into the cavity 4 of the body 5, and one end of the piston rod 7 is connected to the piston 6 and the other end is connected to the piston handle 8. The volume of the tissue block cut by the special-shaped cutter head is uniform, avoiding omissions in the transfer process, and easy to take out. Just push the piston handle 8 gently to the side with the blade, and the piston 6 can push out the specimen cut in the cavity 4. Simple and practical.

Abstract

A small tissue sampling knife device is provided. The pathological small tissue sampling knife has a body, the body is tubular, one end of the body is formed with a knife head, and the other end is inserted into a piston. The knife head is composed of three blades, two of which are It has a V-shaped angle and is connected to the third curved blade. The piston is inserted into the cavity of the body, and one end of the piston rod is connected to the piston and the other end is connected to the piston handle. The invention effectively cuts and holds pathological small tissues tightly to avoid tissue omission, ensures uniform volume of cut small tissues, and prepares for further diagnosis and treatment.

Description

technical field [0001] The invention belongs to the field of tissue sampling tools, and in particular relates to a small tissue sampling knife device. Background technique [0002] Sampling is a very important step in pathological tissue diagnosis. It is to select biopsies or surgical specimens submitted for inspection, and then put them in the specimen box for subsequent processing. The current sample collection device is usually an ordinary surgical forceps. This type of surgical forceps does not have a blade, so sampling is very difficult, and it is easy to slip during the clamping process, resulting in loss of specimens, and it cannot guarantee that the volume of each sample is the same, which is not good for diagnosis. Therefore it is necessary to improve. Contents of the invention [0003] The technical problem solved by the present invention is to provide a small tissue sampling knife device, which can effectively cut and hold small tissues tightly to avoid tissue ...
