Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a special cutting tray for intraoperative autologous parathyroid gland implantation. Background Art

[0002] The workflow for intraoperative parathyroid tissue testing is as follows: draw 0.2~0.3 ml of normal saline with a 1 ml syringe and drop it onto the parathyroid gland; after pinching the parathyroid gland twice with toothed forceps, draw the mixed solution of normal saline and parathyroid tissue fluid, and drop it onto parathyroid test paper to detect whether the tissue is parathyroid gland. If it is confirmed as parathyroid gland, the parathyroid tissue needs to be chopped with a knife before implantation. Currently, there is no special cutting tray available for intraoperative detection of parathyroid tissue. Medical staff usually use the curved tray in the sterile pack to hold and cut the tissue. Since the curved tray is a container with an open top, it is inconvenient to pour the tissue from the curved tray into the muscle during implantation, making the operation time-consuming and labor-intensive. In addition, the bottom surface of the curved tray is flat, and the tissue mixed solution spreads flat in the curved tray, resulting in a very low liquid level of the mixed solution, which is also inconvenient for a syringe to directly draw the solution and delays the treatment efficiency. Summary of Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a special cutting tray for intraoperative autologous parathyroid gland implantation, which is used to solve the problem of time-consuming and labor-consuming operation caused by the lack of a special cutting tray during traditional parathyroid tissue implantation.
