Medical clinical tumor sampling device

Abstract

The invention discloses a medical clinical tumor sampling device. The medical clinical tumor sampling device comprises an installing plate; a PLC controller and an electric stretchable rod are arranged on the upper surface of the installing plate respectively, the input end of the PLC controller is electrically connected with the output end of an externally-arranged power source, the input end of the electric stretchable rod is electrically connected with the output end of the PLC controller, a fixing plate is arranged on the side surface of the stretchable end of the electric stretchable rod, a connecting plate is arranged on the lower surface of the fixing plate, and a stepper motor is installed on the side surface of the connecting plate. According to the medical clinical tumor sampling device, a manual-sucking sample collecting mode is replaced with the electric mode, the sucking force is easy to grasp, and harm to patients is not prone to occurrence; as controlling is carried out through the PLC controller, controlling is concentrated and capable of saving force, and operation is easy; movement of a sampling pipe and movement of a sampling needle head are controlled by the stepper motor, the internal inserting depth of the patients can be determined, the accuracy is high, and secondary damage to the patients is avoided; meanwhile, a distance measuring sensor is arranged and used for measuring the inserting depth of the sampling needle head, and the accuracy is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical clinical tumor sampler. Background technique [0002] At present, tumors, as a high-incidence disease, are attracting more and more attention; after doctors discover tumors, they need to take samples to test whether the tumors are malignant or benign, which is convenient for doctors to treat symptoms. Tumor sampling can be achieved by a scalpel, but this method The wound is large, causing great harm to the patient. However, most of the existing medical clinical tumor samplers use manual suction to collect samples. The suction force is not easy to control, and it is easy to cause harm to the patient. To be sure, it can only be estimated by medical staff, and the accuracy is low, which may cause secondary harm to the patient. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and pr...

[0002] At present, tumor, as a high-incidence disease, is attracting more and more attention; after a doctor finds a tumor, he needs to take a sample to test whether the tumor is malignant or benign, so as to facilitate the doctor's symptomatic treatment. Tumor sampling can be achieved by a scalpel, but this method The wound is large, which causes great harm to the patient. However, most of the existing medical clinical tumor samplers use manual suction to collect samples. Definitely, it can only be estimated by medical staff, the accuracy is low, and it may cause secondary harm to patients
