Simulation device for mammary gland rotary cutting needle or puncture needle training under ultrasound

Abstract

The invention discloses a simulation device for mammary gland rotary cutting needle or puncture needle training under ultrasound, and relates to interventional instruments such as rotary cutting needles and puncture needles, the simulation device comprises an outer skin, a filler, a simulation lump, a bottom plate and an anti-skid module, the outer skin is arranged on the upper surface of the bottom plate, the filler is arranged in the outer skin, the simulation lump is arranged in the filler, and anti-skid modules are symmetrically mounted on the lower surface of the bottom plate. According to the invention, the tissue texture can be simulated under the ultrasonic image, and under the observation of the ultrasonic image, the tumor implantation can realistically simulate the ultrasonic image of the breast benign mass. A rotary cutting needle or a puncture needle can be used for excision, no obvious needle passage or cavity is left in an ultrasonic image when the rotary cutting needle or the puncture needle is pulled out, the real simulation of training is improved, the hardness of the simulated lump is controlled to show a water-containing solid under ultrasound, and the simulated lump can be cut off by the rotary cutting needle or the puncture needle and pulled out through a negative pressure pipeline.

Description

technical field [0001] The invention relates to interventional instruments such as rotary cutting needles and puncture needles, in particular to a simulation device for ultrasonic mammary gland rotary cutting or puncture training. Background technique [0002] At present, there is no device specially used for breast surgery training. It is generally used for observation under ultrasound images. Existing devices are mainly simulated from the aspects of appearance, feel, and ultrasound images. Usually, soft materials such as silica gel and latex are used for breast surgery. The main filling body, a hard material is built into the filling main body to simulate a mass, so that these hard objects can be clearly identified under ultrasound. Usually, the device is made of silicone or latex material, in order to obtain a similar feel to human breasts , to help users train the gestures, etc., the soft filler is placed on a fixed base so that it cannot be moved during use.

[0003] Breast models with simulated masses, which are usually used for ultrasound observation, cannot be used for destruction. Once the needle probe is inserted into the model and pulled out, it will leave an obvious needle track under ultrasound, which will affect subsequent use and observation. In addition, the model device commonly used for image observation cannot simulate the ultrasonic image of the tissue, and some ultrasonic models that can simulate the tissue image cannot be destroyed by puncture, and there is no implant for simulating the mass.
