Tumour treatment intervention apparatus

Abstract

The invention discloses a tumour treatment intervention apparatus including a needle tubing and a support seat, the needle tubing is plugged into a circular hole left in the middle of the support seat, the pipe walls at the two sides of the needle tubing are provided with tooth bars, the inner cavities at the two sides of the support seat are provided with grooves, the walls of the grooves are connected with ratchet wheels and pawls through shafts, the pawls are arranged at the upper sides of the ratchet wheels, the pawls are engaged with one sides of the ratchet wheels, and the other sides of the ratchet wheels are engaged with the tooth bars, and the inner end parts of adjusting rods are hinged to the upper ends of the pawls. The intervention apparatus controls the distance of the syringe needle inserting into the human body through the ratchet wheel and tooth bar structure, so that the distance from the syringe needle to the pathological part is controlled in high precision. By means of the support leg structure, the use stability of the intervention apparatus is improved, and by means of the support leg telescoping structure, the intervention apparatus can make adjustment according to different body parts, so that the use scope of the apparatus is enlarged. In addition, the intervention apparatus has the advantages of simple use, high precision, and low cost.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an interventional device for tumor treatment. Background technique [0002] Interventional therapy has attracted widespread attention due to its characteristics of small trauma, fast recovery, and wide application range. It has a wide range of applications in the treatment of tumors. Interventional therapy needles are commonly used in interventional therapy. Interventional therapy needles can directly act on drugs. In the lesions, the treatment effect is good. Traditional interventional therapy needles need to rely on sophisticated control instruments for auxiliary use. The cost of equipment is relatively high, exceeding the cost budget of small hospitals, while traditional hand-held interventional therapy needles are poor in stability. The intervention distance is difficult to grasp, it is only suitable for experienced doctors, and it is difficult to promote. Therefore, we propose...
