Multifunctional tumor injector

Abstract

The invention discloses a multifunctional tumor injector. The multifunctional tumor injector comprises an injector body and a puncture needle body. An injector cylinder is arranged in the injector body. A puncture needle is arranged in the puncture needle body. A puncture needle sleeve is connected to the outer side of the puncture needle detachably. A first puncture needle barb is arranged on thelower portion of the puncture needle. A second puncture needle barb is arranged on the upper portion of the puncture needle. A puncture needle through hole is formed in the lower portion of the puncture needle. A puncture needle in-vitro marker is arranged at the top of the puncture needle. The multifunctional tumor injector has the advantages that the injector body and the puncture needle are arranged, and the puncture needle is connected with the injector body flexibly through a fastener, so that the position of a tumor of a patient can be marked and fastened by multiple angles; the markingbarb and the auxiliary fastening barb are arranged, so that the tumor can be marked and fastened efficiently; through the through hole and a flap capable of being opened in a unidirectional way, marking liquor can be supplemented at any time, so that the capability of efficient tumor marking is guaranteed.

Description

technical field [0001] The invention relates to the technical field of syringes, in particular to a multi-angle tumor syringe. Background technique [0002] Tumor tissue differs from the normal tissue from which it originates in varying degrees in terms of cell morphology and tissue structure, and this difference is called atypia. Atypia is the morphological manifestation of abnormal differentiation of tumors. A small atypia indicates a high degree of differentiation, and a large atypia indicates a low degree of differentiation. Distinguishing the size of this atypia is the main histological basis for diagnosing tumors and determining benign and malignant tumors. The atypia of benign tumor cells is not obvious and is generally similar to its source tissue. Malignant tumors often have obvious atypia. [0003] The tumor marker syringe is a syringe for lung tumor patients to determine the tumor location and lock the tumor. It is mainly composed of six parts: With the devel...

Problems solved by technology

[0004] However, the tumor marker syringes currently used still have some deficiencies. Breathing is a normal vital sign of the human body. Among them, the lungs will continue to expand and contract with respiration, so the position of the tumor in the lungs can not be determined whether it is in the lungs or relative to the inside of the human body, which directly leads to the No existing radiography equipment can locate the tumor in the lung for preoperative radiography. The current practice is to use active dyes such as gentian violet to mark the lungs before surgery. The marking time of this method is short, and the marked dye is metabolized by the human body in a very short time, resulting in poor marking effect during the actual operation, and it is difficult to find the location of the tumor, which cannot meet the needs of use. During the process, the angle of the needle punctured by the syringe is relatively fixed, so the tumor position cannot be fixed and marked from different angles, which reduces the effect of tumor injection marking and fixation. In addition, there may be a period of time between marking and actual surgery. , but the labeling solution is easily metabolized, and it is difficult to replenish the labeling solution later
