Problems solved by technology

Most of the existing B-ultrasound-guided puncture positioning devices are composed of brackets with dials, angle scales, needle insertion length scales, shafts, puncture guide grooves, adjustment devices, etc. (patents: CN87208523, CN87211208). Very inconvenient, flexible, and the puncture angle is limited, so it has not been widely used

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0010] According to Fig. 1 and Fig. 2 as can be known, the feature of the present invention is on the B-ultrasonic probe 1 fixed retractable pointing needle 4 by the fixed seat 3, and the fixed seat 3 is fixed on the B-ultrasonic probe 1 lower end by the fixed ring 2 (B-ultrasonic probe The end without mark on the top is the lower part), and the retractable pointing needle 4 is installed on the fixed seat 3, so that the retractable pointing needle 4 is connected with the B-ultrasound probe 1. The retractable pointing needle 4 on the fixed seat 3 is perpendicular to the longitudinal section of the B-ultrasound probe 1, and the length of the retractable pointing needle 4 can be adjusted arbitrarily. Carry out B-ultrasound exploration in a conventional method to determine the location of the uterine fibroids. On this basis, after further determining the central part of t...

Abstract

The present invention discloses a telescopic ultrasonic positioning director, comprising the probe of the B model ultrasonic monitoring instrument, the telescopic fingerpost and the fixed seat. The fixed seat is mounted by fixed ring, and the telescopic pointer on the seat is connected with the probe. When longitudinal scan is done, the telescopic pointer can be pulled out along horizontal direction, and collinear with the longitudinal section of probe to direct puncturing. The telescopic pointer can be retracted back and folded upwards to vertical direction when it is not used to position. The invention is simple in structure and convenient to operate, in particular to tiny wound therapeutic puncture position in gynaecologic uterus guided by ultrasonic. It is effective to prevent penetration of normal histiocyte by mistake, decrease the difficulty of puncture, increase the accuracy of puncture and save the puncture time.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically relates to a retractable ultrasonic positioning guide, which is especially suitable for puncture positioning in transvaginal intrauterine minimally invasive surgical treatment under the guidance of gynecological ultrasound. Background technique [0002] At present, the development of minimally invasive surgery is very rapid, and B-ultrasound-guided puncture therapy is widely used in clinical practice. The positioning device for B-ultrasound-guided puncture also emerged as the times require. Most of the existing B-ultrasound-guided puncture positioning devices are composed of brackets with dials, angle scales, needle insertion length scales, shafts, puncture guide grooves, adjustment devices, etc. (patents: CN87208523, CN87211208). It is inconvenient and flexible, and the puncture angle is limited, so it has not been widely used. After sear...
