Document Type and Number:
WIPO Patent Application WO/2021/179208
Kind Code:
A1
Abstract:
Disclosed are a needle groove plate (5), a puncture support (100), and a biopsy device. The puncture support (100) comprises a main body (1), a rod (4), and a needle groove plate (5), wherein the main body (1) can be connected to an ultrasonic probe (200) and is provided with a channel (13), and the length of the channel (13) is less than the length of the rod (4); the rod (4) can enter the channel (13) from a first end of the rod and can slide back and forth in the channel (13) in a first direction, and the first direction is parallel to an extension direction of the rod (4); and the needle groove plate (5) is fixed to a second end of the rod (4), and the needle groove plate (5) is provided with at least one needle penetration hole (513) parallel to the first direction. In the device, not only is the structure of the puncture support (100) optimized and the size of the puncture support reduced, but also the manufacturing cost is reduced; the rod (4) and the main body (1) can be flexibly and telescopically operated, such that the position of the needle groove plate (5) is adjustable, thereby preventing the needle groove plate (5) from pressing the perineum of a patient, and reducing discomfort in a puncture process; furthermore, a puncture needle can be separated from the puncture support (100) and the ultrasonic probe (200) during surgery, thereby facilitating flexible operation by a doctor.
