Description

Interventional therapy device for tumors Technical Field The invention relates to the technical field of medical equipment, in particular to an interventional therapy device for tumors. Background Tumor interventional puncture drainage is one of non-vascular interventional techniques, and is especially used in treating tumor via percutaneous puncture to drain or aspirate tumor relevant focus, such as abscess, cyst, effusion or necrotic tissue, under image guidance, such as ultrasonic, CT or MRI, to relieve symptoms, control infection or assist treatment. It has wide application in tumor therapy, especially for malignant tumor patients with effusion, abscess or obstruction. When the tumor is involved in puncture drainage, in order to prevent the drainage tube from accidentally slipping, shifting or twisting so as to ensure the drainage effect, the drainage tube needs to be fixed on a human body, and the fixing process of the drainage tube usually needs to be combined with an internal structural design and external fixing measures. The internal structural design generally comprises a pigtail type drainage tube, a mushroom-shaped head or petal type drainage tube, a balloon type drainage tube and the like, and the external fixing measures generally comprise skin suturing and fixing, drainage tube fixing and sticking and fixing, adhesive tape fixing, dressing covering and fixing and the like. The current common drainage tube fixing mode has the defects that firstly, a drainage hole on a drainage tube is easy to block to influence the puncture drainage process, secondly, external fixing measures are easy to cause uncomfortable feeling to a patient, for example, a suture can cause pain to the patient, and a fixing patch can cause discomfort and anaphylactic reaction to the skin of the patient. The information disclosed in the background section of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art. Disclosure of Invention Based on this, it is necessary to provide a tumor interventional therapy device in order to solve the problems of the conventional interventional therapy device. The above purpose is achieved by the following technical scheme: The interventional therapy device for tumors comprises a drainage tube and a grabbing plate arranged on the drainage tube, wherein a plurality of drainage holes are formed in the side wall of the drainage tube, the drainage tube is used for conducting drainage through the drainage holes after penetrating into a human body, when the drainage holes are blocked, the drainage tube can deform so as to expand the drainage holes, the grabbing plate is provided with a plurality of grabbing teeth arranged at intervals, and when the grabbing plate is attached to the skin of the human body, the grabbing teeth are mutually close to each other so as to grab the skin of the human body. Further, the drainage tube is provided with an internal end and an external end after penetrating into a human body, a lead is arranged from the internal end to the external end on the drainage tube, and the drainage tube deforms when the lead is pulled from the external end. Further, a plurality of drainage holes are formed at intervals along the length direction of the drainage tube, and the lead wire penetrates through the drainage tube and is positioned on the opposite side of the drainage hole. Further, two adjacent drainage holes are respectively positioned at two sides of the drainage tube. Further, the grabbing plate is annular and sleeved at the outer end, the inner side of the grabbing plate is fixed with the outer end, and the grabbing plate can deform along the radial direction of the grabbing plate, so that the grabbing teeth are close to or far away from each other. Further, a winding plate is arranged on the outer side of the grabbing plate, and the lead is wound on the winding plate after being led out from the inner end to the outer end of the body. Further, a sliding cylinder is arranged in the drainage tube, the lead is led out after passing through a gap between the drainage tube and the sliding cylinder, and the sliding cylinder can pull the lead when sliding far away from the inner end of the body. Further, a sealing cylinder is fixedly sleeved on the sliding cylinder, and when the sliding cylinder slides along the drainage tube, the sealing cylinder can pull the lead. Further, a reset structure is arranged between the sliding cylinder and the drainage tube, so that the sliding cylinder has a tendency of sliding towards the inner end of the body. The drainage tube has the advantages that after the drainage tube is punctured into a human body and is placed in a tumor related focus, drainage is carried out through the drainage hole, when the drainage tube is blocked, the drainage tube
