Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a tumor detection sampling device. Background Art

[0002] Tumor detection is a key means of early detection and diagnosis of tumors, which can significantly improve the success rate of treatment and patient survival rate. Before performing tumor detection, a sampling device is required to sample the tumor.

[0003] After searching, the Chinese patent application number is "CN202310000594.5", which is specifically a tumor detection sampling device and method, including a horizontal connecting block, the outer side of the guide block is provided with a locking clamp connector, the bottom of the fixed column is connected to a cutting blade through a horizontal cutting piece, and the bottom of the positioning rod is connected to a disposable sampling clamp through a replacement lock card. The present invention sets a shock-absorbing and buffering member. When the guide block is restored under the action of the reset spring, the air push plate can discharge the gas drawn into the air connecting cavity through the second air connecting hole. In this process, since the diameter of the air connecting cavity is larger than the diameter of the second air connecting hole, the gas in the air connecting cavity will be slowly squeezed out, so that the movement of the guide block can be decelerated.
