The sphere 12 A pressure plate 13 is fixedly installed on the outside, a mounting block 14 is fixedly installed on the front of another connecting block 7, a sliding rod 15 is slidably installed on the front of the mounting block 14 near the bottom, and a stop plate is fixedly installed on one end of the sliding rod 15. A tooth groove 16 is opened on one side of one of the fixed blocks 4, and the tooth groove 16 is adaptively matched with the stop block. A screw rod 17 is rotatably installed on the other connecting block 7 and the positioning block 9, and a rotating seat 18 is rotatably installed on the outside of the screw rod 17 and the round rod 8. A connecting plate 19 is fixedly installed between the two rotating seats 18, and an arc plate 20 is fixedly installed at the bottom center of the connecting plate 19.

[0025] In this embodiment, a fixing spring is disposed outside the sliding rod 15 , one end of the fixing spring is fixedly mounted on the abutment plate, and the other end of the fixing spring is fixedly mounted on the mounting block 14 .

[0026] The elastic force of the fixing spring can make the abutment plate and the tooth groove 16 mesh with each other, thereby fixing the position of the slider 6.

[0027] In this embodiment, the pressing plate 13 is arc-shaped, and the top surface of the supporting platform 2 is arc-shaped.

[0028] The top surface of the support platform 2 is arc-shaped, which can better fit the patient's head and improve the comfort of treatment.

[0029] In this embodiment, a quick-release hot compress structure 21 is provided at the bottom of the arc plate 20, and the quick-release hot compress structure 21 includes a mounting plate 22 and a mounting plate 23. The mounting plate 22 is slidably installed on the bottom of the arc plate 20 through positioning piles on both sides, and the mounting plate 23 is fixedly installed at the rear of the mounting plate 22 near the top position. A plug block 24 is fixedly installed at the front of the mounting plate 23, and the plug block 24 is adaptably matched with the arc plate 20. A fixing seat 25 is fixedly installed at the front of the arc plate 20 near the top position, and a cavity is opened inside the fixing seat 25. A limit block 26 is clamped inside the cavity, and a metal rod 27 is fixedly installed at the top center position of the limit block 26. A water bag 28 is fixedly installed at the bottom of the mounting plate 22.

[0030] By injecting hot water into the water bag 28, the patient's head can be restrained while hot compress treatment is performed on the patient to reduce the patient's discomfort during the imaging process.

[0031] In this embodiment, one end of the limiting block 26 is triangular, and a limiting groove is provided at the top of the inserting block 24 near one end, and the limiting groove is adaptively matched with the limiting block 26 .

[0032] Through the contact between the insert block 24 and the limiting block 26 , the limiting block 26 can be inserted into the limiting groove to fix the position of the mounting piece 22 .

[0033] In this embodiment, a limit spring is disposed outside the metal rod 27 , one end of the limit spring is fixedly mounted inside the cavity, and the other end of the limit spring is fixedly mounted on the top of the limit block 26 .

[0034] Through the elastic force of the limit spring, when the insert block 24 squeezes the limit block 26, the limit spring is compressed inside the cavity, and when the limit block 26 contacts the limit groove, it is ejected under the elastic force of the limit spring.

[0035] In this embodiment, a water inlet and a water outlet are fixedly installed at both sides of the front of the water bag 28, and one end of the top of the insert block 24 is in an arc shape.

[0036] One end of the top of the insert block 24 is in an arc shape, and when it contacts the triangular surface of the limit block 26, it can squeeze the limit block 26 to compress the limit spring and retract it into the cavity.

[0037] It should be noted that the utility model is a head fixing device for cerebral angiography. When in use, the operator first lets the patient lie flat on the mounting table 1, and places the patient's head on the supporting table 2. By pulling the sliding rod 15, the stop block is disengaged from the tooth groove 16, so as to adjust the slider 6 to a suitable position, and ensure that the arc plate 20 is located near the upper position of the patient's face. The operator rotates the threaded rod 10 so that the threaded rod 10 drives the pressing plate 13 forward, and adjusts the position of the pressing plate 13 through the ball table 12 so that the pressing plate 13 contacts and is fixed with the patient's shoulder.

[0038] Inject hot water of appropriate temperature into the water bag 28, and fix the installation piece 22 to the bottom of the arc plate 20 through the insert block 24 and the positioning pile. When the insert block 24 moves forward, it will squeeze the triangular surface of the limit block 26 and make the limit block 26 compress the limit spring and retract into the cavity. When the limit block 26 contacts the limit groove, it will pop out under the elastic force of the limit spring, so that the position of the insert block 24 is fixed, thereby fixing the position of the installation piece 22;

[0039] Rotate the screw rod 17 to make the arc plate 20 descend under the action of the rotating seat 18, so that the water bag 28 can contact the patient's eyes to perform hot compress massage and reduce the patient's discomfort during cerebral angiography;

[0040] After completing the angiography, the metal rod 27 is pulled to retract the limit block 26 into the cavity. At this time, the insert block 24 is no longer limited by the limit block 26. The operator removes the entire quick-release hot compress structure 21 by pulling the mounting plate 22 to facilitate disinfection and avoid cross infection.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
