Problems solved by technology
[0003] When medical personnel perform puncture on tumor patients, they need to determine the location of the lesion through CT scan first, and then use the puncture needle to perform puncture work. During the process of tumor puncture, the puncture needle may deviate from the original track due to uneven application of force. Phenomena, when the deviation angle is too large, the medical staff may need to pull out the puncture needle to perform the puncture work again, which will increase the physical pain of the patient, and also reflects the difficulty of tumor puncture

The invention discloses a tumor puncture guiding device which comprises two mounting seats and an auxiliary mechanism, the auxiliary mechanism comprises an arc-shaped sliding rail, the outer wall of the arc-shaped sliding rail is slidably sleeved with a movable block, a mounting plate is arranged at the bottom of the movable block, a rectangular hole is formed in one side of the top of the mounting plate, and an inner cavity of the rectangular hole is slidably sleeved with a lifting rod; a puncture needle is arranged at the bottom of the lifting rod, a first T-shaped sliding groove is formed in one side of the lifting rod, a first T-shaped sliding block is arranged on one side of the inner wall of the rectangular hole, a first reset spring is arranged on the top of the first T-shaped sliding block, and a calibration mechanism is arranged on the other side of the top of the mounting plate. According to the tumor puncture device, the arc-shaped sliding rail, the movable block, the mounting plate and the lifting rod are arranged, the puncture needle is supported through a supporting frame composed of the arc-shaped sliding rail, the movable block, the mounting plate and the lifting rod, meanwhile, the movement track of the puncture needle is limited, the phenomenon that the puncture needle deviates from an original track due to uneven force application is avoided, and the difficulty of tumor puncture is reduced.
Description
technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a tumor puncture guide device. Background technique [0002] Tumors refer to new organisms formed by the proliferation of local tissue cells under the action of various tumorigenic factors, because these new organisms are mostly space-occupying massive protrusions, also known as neoplasms. Tumor biopsy is a very important method for diagnosing benign and malignant tumors. Tumor biopsy is usually carried out under the guidance of CT or ultrasound. When the location of the tumor is determined, a biopsy needle is used to puncture the tumor tissue to take out the appropriate tumor tissue and send it for pathological examination to determine whether it is a benign tumor or a malignant tumor. [0003] When medical staff puncture a tumor patient, they need to use CT scan to determine the location of the lesion before using the puncture needle for puncture work. Phe...
