Description

PUNCTURE SUPPORT AND BIOPSY DEVICE

Technical Field

The present application relates to the technical field of medical supplies, in particular to a puncture support and a biopsy device.

Background Art

As people's way of living has changed in recent years, prostate disease in men is in the trend of rising, which seriously threatens people's health and quality of life Prostate disease is a common disease especially among older men At present, generally prostate biopsy is used to detect and troubleshoot prostate diseases. In ultrasound biopsy, a small amount of sample tissues needs to be taken out from different parts of the prostate for the purpose of definite diagnosis. Biopsy is less invasive and more accurate, and thus has been widely used in clinic applications. Common sampling ways of biopsy are by way of rectum and by way of perineum. There are some disadvantages by way of rectum, which are mainly as follows: L an ultrasonic probe and a puncture support reach the position of the prostate via the rectum entrance, and bacteria in the rectum easily lead to a high risk of being infected; and, 2. puncture positions are limited and there are some blind areas. Therefore, biopsy by way of perineum is the mainstream method of prostate biopsy at present, and has advantages of, e.g., aseptic operations, low risk of being infected and comprehensive sampling.

The puncture operation by way of perineum requires a cooperative use of the puncture support with the ultrasonic probe. Currently the puncture support by way of perineum used in hospitals mainly adopts a puncture support similar to a grid screen plate, and the puncture support can be used in puncture surgery only after being fixed by a dedicated stepper. There are the following disadvantages: 1. a dedicated stepper needs to be used, but the stepper is expensive, and its large size could easily interfering with a doctor operations' flexiblity; 2. the function of separating a needle from a support in the surgery cannot be realized; and 3. a screen plate puncture support has a large volume, and severely increases discomfort in a patient in the surgery when it is placed at the perineum.
