Detailed ways

Interventional surgery through the right radial artery requires good fixation of the right upper limb, keeping the overall curve of the right upper limb smooth without excessive bending, and in order to facilitate the puncture, the wrist needs to be raised. In this protocol, a fixation frame for interventional surgery through the right radial artery is proposed:

An arm fixation frame for interventional surgery through the right radial artery, including a fixed plate 13 for placing the right arm, the front end of the fixed plate 13 is retractable, and there is a wrist pad 10 for raising the wrist; the rear end of the fixed plate 13 is movable Type is installed on 9 mouths of a fixed card, and 9 mouths of fixed card are detachably installed on the edge of bed board 16 of operating bed.

As shown in Figures 1 and 3, the main structure of this solution includes a fixing plate 13, which is used to support and fix the patient's upper arm and part of the forearm. It can be seen from the figure that the longitudinal section of the fixing plate 13 is in the shape of an arc, and in fact, the degree of the central angle corresponding to the arc is 120°-150°. Then, after the patient puts the upper limb in the fixed plate 13, it cannot move relative to the left and right. The raised structure at the two ends of the fixed plate 13 limits the moving position of the right upper limb, and is also convenient for the placement of the patient's upper limb. For different patients, the lengths of their upper limbs are different, so the front end of the fixing plate 13 can be stretched to adapt to the different lengths of the upper limbs of the patients. The wrist pad 10 provided here is to elevate the patient's wrist to facilitate puncturing. As shown in Figure 3, the palm of the right palm of the patient faces upward during the puncture, exposing the inner side of the wrist, and the wrist pad 10 is placed at the intersection of the root of the patient's palm and the front of the forearm, that is, the back of the wrist, so that the front of the arm is raised , to facilitate the puncture process. In order to facilitate the installation of the fixing plate 13, the rear end of the fixing plate 13 is movably installed on a fixing device. The fixation device can be installed on the operating bed in various configurations, and is preferably installed on the edge of the operating bed to occupy as little space as possible on the operating bed.

As shown in Figure 2, a fixture structure is provided in this example, including a bottom plate 5 and a top plate 2 parallel to the bottom plate 5, a side edge provided between the side edge of the bottom plate 5 and the bottom of the top plate 2 through the vertical top plate 2 and the bottom plate 5 The plates 7 are connected, the upper surface of the top plate 2 is provided with a rotating shaft 15 , and the fixed plate 13 is installed on the rotating shaft 15 .

The structure of the fixing device is a bayonet structure, which is similar to a "匚" shape, "bites" on the edge of the operating bed, and is convenient for installing the fixing plate 13 . What side plate 7 connects is the bottom of the edge of bottom plate 5 and top plate 2, rather than the edge of top plate 2, and the edge of top plate 2 stretches out side plate 7 a part, and this part can carry out certain support to fixed plate 13 bottoms.

The specific fixing method is that a push plate 4 is arranged between the top plate 2 and the base plate 5, and a screw rod 6 with a knob passing through the base plate 5 is provided at the bottom of the push plate 4, and the screw rod 6 and the base plate 5 are threadedly fitted.

Turn the knob by hand, and the screw rod 6 rotates and advances, so that the push plate 4 moves close to the top plate 2 . After inserting between the top board 2 and the bottom board 5 to the edge of the operating bed, turn the knob so that the bed board 16 of the operating bed is clamped between the top board 2 and the push plate 4, so that the fixture is fixed on the bed board 16.

In order to realize the horizontal rotation function of the fixed plate 13, the rotating shaft 15 is covered with the mounting plate 3, and the rear end of the fixed plate 13 is mounted on the mounting plate 3 through a hinge.

As shown in the figure, after the fixing plate 13 is arranged on the mounting plate 3 , it has an integrated structure with the mounting plate 3 . Through the hinge installation, the fixing plate 13 can be at different angles relative to the mounting plate 3, so as to realize the function of lifting the arm as a whole, so as to facilitate the operation process. When the mounting plate 3 rotated around the rotating shaft 15, the mounting plate 13 also rotated with the mounting plate 3, so that the mounting plate 13 could be rotated in the horizontal plane, which was equivalent to the fixed plate 13 rotating with a certain point on the edge of the bed board 16 as the center of circle. , to adjust the distance between the wrist and the operating table.

The angle between the fixed plate 13 and the operating bed board 16 can be changed by the hinge, and after the angle is changed, it can be fixed by the pole 8 . The bottom of the fixed plate 13 is provided with a pole 8, one end of the pole 8 is hinged on the side plate 7, and the bottom of the fixed plate 13 is distributed with a plurality of fixed clips 9 cooperating with the pole 8 at intervals along the length direction of the fixed plate 13.
