Description
Technical Field
The invention relates to the field of medical surgical instruments, in particular to a cyst wall tissue biopsy device.
Background
There are various types of cysts in the clinic, for example: renal cyst, hepatic cyst, and the like. Taking renal cyst as an example, most of renal cysts are benign lesions in clinical practice. However, when the CT examination shows that the wall of the sac is thick (thin-walled cysts are basically benign), there are bleeding in the sac, and there are floccules in the sac, there is a possibility of malignant cystic lesions. Clinically, the current traditional operation mode for cystic lesions on the kidney is cyst topping operation, which can cause cyst fluid to flow out in the operation process, and if the cyst is malignant, artificial cancer cells can be planted and transferred in vivo. If it is malignant, the operation of renal resection should be performed clinically. However, at present, no device for biopsy of cyst wall and no outflow of cyst fluid exists clinically, so that the excised cyst wall is usually subjected to quick frozen biopsy in the process of clinical ascending cyst topping-off, and if the biopsy is malignant and then the nephrectomy is performed, the method has the risk of artificial cancer cell planting and transfer. Even if the similar biopsy device exists, a small opening is cut in the tissue of the capsule wall, then the ordinary aspirator head is inserted into the capsule cavity to suck out the capsule liquid and then cut off, a part of the capsule liquid is extracted by a thick needle head, the needle eye is enlarged after the internal pressure of the capsule is reduced, the ordinary aspirator head is put in to suck the capsule liquid and then the capsule wall is cut off, the operation of the method brings huge wound of the incision to a patient, and the problems that the internal liquid of the capsule leaks out to pollute the abdominal cavity, the capsule liquid is difficult to extract and the like exist.
Therefore, there is a need for a biopsy device for renal capsule wall tissue to facilitate the sampling of renal capsule wall specimens and reduce the risk of cancer cell implantation metastasis.
