The present application relates to the technical field of cardiac pacing electrode, in particular to a telescopic cardiac pacing electrode, which comprises a pulse pacemaker and an electrode lead, the electrode lead comprises an insertion end, a connecting sleeve, a conductive core wire and an electrode end, the insertion end, the connecting sleeve and the electrode end are sequentially fixedly connected, the insertion end is insertedly matched with the pulse pacemaker, the connecting sleeve is internally provided with the conductive core wire, the two ends of the conductive core wire are respectively connected with the insertion end and the electrode end, and the pulse pacemaker generates a pulse electric signal which is transmitted to the inside of an organ through the electrode end; in the present application, the telescopic members and the fixing members are staggered in the subcutaneous section, the initial length is the shortest, the spacing of the fixing members anchored in the subcutaneous tissue is increased with the growth of the patient's trunk, the telescopic members are axially stretched, the length adjustment range covers the entire growth period from childhood to adulthood, the risk of electrode lead tightness, electrode displacement or breakage is fundamentally eliminated, and secondary surgery is avoided.

The application relates to a kind of integrated minimally invasive diagnosis and treatment devices applied to jaw cyst biopsy and window drainage, comprising biopsy assembly and positioning sleeve, wherein the biopsy assembly comprises sleeve, and the outside of sleeve is provided with blade.The positioning sleeve has an insertion section, which is provided with a self-tapping thread.The inside of the positioning sleeve has a through-type operating channel, which is provided for biopsy assembly insertion operation.Compared with the prior art, after the insertion of the positioning sleeve is completed and the biopsy operation is completed, the operating channel in the inside can become a shared channel for subsequent nursing operations, and medical staff can complete biopsy sampling and window drainage through the operating channel, thereby avoiding secondary puncture or secondary surgery on the patient, and significantly shortening the operation time and the postoperative recovery period of the patient.The device can realize simultaneous pathological sampling and self-tapping implantation, has the advantages of convenient operation and high overall practicability.

The application provides a neurosurgical suction tube with a sensing function, and belongs to the technical field of medical devices. The technical points are as follows: the neurosurgical suction tube body is a flexible bending structure with a rhombic cutting notch and a hollow tube with an externally-attached optical fiber transmission path; a multi-sensor fusion sensing device comprises: four groups of signal acquisition lines which are uniformly and spacedly arranged along the periphery of the neurosurgical suction tube body; each group of the signal acquisition lines comprises: an end electrode, two groups of Bragg grating nodes, an optical path transmission optical fiber and an electrical transmission copper wire; the first group of Bragg grating nodes is located in correspondence with the bending structure; the electrical signal and the optical signal are independent of each other in information acquisition and transmission, and do not affect each other. By using the technical scheme, the force in the operation process can be sensed, the surface reaction force distribution and the positioning depth information of the hard package body of the intraoperative tissue are reconstructed through force touch, and efficient electrode impedance spectrum detection and imaging are guided.
