Interventional needle fixing device for clinical tumor treatment

Abstract

The invention discloses an interventional needle fixing device for clinical tumor treatment. The interventional needle fixing device comprises a height adjusting unit and an angle adjusting unit. Theheight adjusting unit comprises a lifting rod rack limiting barrel, a mounting plate and a gear, the lower end of the limiting barrel is fixedly connected with the right side of the upper surface of abottom plate, the upper end of a lifting rod penetrates through a through hole in the right side of the lower surface of the bottom plate, the side surface of the lifting rod is in sliding connectionwith the side surface of the limiting barrel, a rack is arranged on the side surface of the lifting rod, a through groove corresponding to the rack is formed in the side surface of the limiting barrel, two mounting plates are arranged on the side surface of the upper end of the limiting barrel, the middles of the opposite side surface of the two mounting plates are rotationally connected with themiddles of the left side surface and the right side surface of the gear respectively, and the gear is meshed with the rack. According to the interventional needle fixing device for clinical tumor treatment, an interventional needle can be stably fixed, the injury to a patient due to shaking of the interventional needle during treatment is prevented, and the burden and the working difficulty of amedical staff are reduced.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an interventional needle fixation device for clinical tumor treatment. Background technique [0002] Like internal medicine, surgery, obstetrics and gynecology, and pediatrics, oncology is a second-level discipline of clinical medicine, which is divided into medical oncology, radiotherapy oncology, and surgery oncology. It has become one of the most important clinical treatment methods. The more commonly used method is to use a puncture needle to directly puncture the blood supply artery of the lesion through the body surface. The puncture needle is generally longer than ordinary needles, and most of the existing operations are performed by operators. Hand-held operation requires doctors to have rich experience and stable techniques, but it takes a long time for interventional treatment. Operators are prone to hand fatigue during long-term operations, and need...

[0002] Like internal medicine, surgery, obstetrics and gynecology, and pediatrics, oncology is a second-level discipline of clinical medicine, which is divided into medical oncology, radiotherapy oncology, and surgery oncology. It has become one of the most important clinical treatment methods. The more commonly used method is to use a puncture needle to directly puncture the blood supply artery of the lesion through the body surface. The puncture needle is generally longer than ordinary needles, and most of the existing operations are performed by operators. Hand-held operation requires doctors to have rich experience and stable techniques, but it takes a long time for interventional treatment. Operators are prone to hand fatigue during long-term operations, and needle holding may occur. In an unstable situation, if the puncture needle shakes, it will affect the effect of the treatment, and seriously cause secondary injury to the patient, increasing the burden on the medical staff and the difficulty of work
