Problems solved by technology

The operation of blood vessel puncture or nerve block requires the cooperation of both hands. At this time, the fixing work of the B-ultrasound probe needs to be completed by other medical personnel, which is a great waste of medical human resources.
The utility model patent (an ultrasonic probe fixing bracket) with the application number of 201620114925.3 discloses an ultrasonic probe fixing bracket, which uses the large friction force of the metal hose itself to realize the free positioning function of the ultrasonic probe. Although the method can play a role in fixing the ultrasonic probe, it takes a lot of effort to adjust the metal hose, which is not conducive to the finer operations performed by doctors when using the ultrasonic probe to detect the internal conditions of patients.

Embodiment 1

[0047] Example 1, when performing ultrasound-guided puncture on a patient, the doctor first selects an appropriate fixer (7-1), connects the fixer (7-1) to the rotating arm VI (7), and then inserts the ultrasound probe Fastened to the holder (7-1). Then hold the ultrasound probe to find a suitable puncture position on the patient. When a suitable position is found, the doctor can depress the pedal assembly (8), and the end of the sliding plate (8-3) slides toward the side of the brake shaft I (8-6), so that the pedal spring (8-4) is compressed, and at the same time 6 brake lines (9) are tightened, and the brake lines (9) move toward the brake shaft I (8-6) side along with the end of the sliding plate (8-3). After the brake cable (9) is tightened, each brake cable (10-6) moves with the brake cable (9), so that each brake pad (10-3) is tightened inward and tightly attached to the friction surface (14), to play the role of rotating arm I (2), rotating arm II (3), rotating arm I...

Embodiment 2

[0048] Embodiment 2, when the photographer is taking pictures, first select a suitable holder (7-1), connect the holder (7-1) with the rotating arm VI (7), and then fix the camera on the holder (7-1) superior. At this time, the camera is not constrained, and the photographer can hold the camera, and adjust the position and angle of the camera in six degrees of freedom in space. When the proper position is reached, the photographer steps on the pedal assembly (8), and the camera will be completely Tethered, the photographer can press the shutter and take a stable picture.

[0049] The above-mentioned X, Y, and Z directions are only for expressing and distinguishing the rotation direction of each revolving pair more clearly, rather than the expression method of the Cartesian coordinate system. For example, the X and Y directions are perpendicular to the Z direction, but the X direction There is a possibility of being parallel to the Y direction.

Abstract

The present invention provides a temporary fixing adjustable support. The temporary fixing adjustable support mainly comprises a base, a rotary arm I, a rotary arm II, a rotary arm III, a rotary arm IV, a rotary arm V, a rotary arm VI, a pedal assembly, six brake lines, six brakes, N hoops and four universal wheels. The multiple rotary arms form a multi-connecting-rod mechanism, a revolute pair between every two rotary arms is rotationally provided with a brake, and the brakes can change friction force of the revolute pair to achieve the fixing effect. The support is simple in structure and relatively low in cost, and can be used for more occasions by changing the structure of a fixer.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a temporarily fixed and adjustable bracket. Background technique [0002] When doctors now perform vascular puncture or nerve block operations on patients, in order to improve the success rate of the operation, they often use B-ultrasound machines to assist them, so that the process of vascular puncture or nerve block operations can be visualized. The operation of blood vessel puncture or nerve block requires the cooperation of both hands. At this time, the fixing of the B-ultrasound probe needs to be completed by other medical personnel, which is a great waste of medical human resources. The utility model patent (an ultrasonic probe fixing bracket) with the application number of 201620114925.3 discloses an ultrasonic probe fixing bracket, which uses the large friction force of the metal hose itself to realize the free positioning function of the ultrasonic probe. Although the m...
