Thereby enabling the patient's head to remain stationary.

The utility model provides a technical scheme that its technical problem adopted is:

The utility model provides a head fixing device of embolectomy is got to blood vessel of brain, includes pillow support, fixed plate, clamp and horizontal straight line actuating mechanism and constitutes, set up the arc wall of placing patient's head on the pillow support, horizontal straight line actuating mechanism's cylinder body is fixed at the fixed plate side, and the fixed plate is fixed in pillow support bottom, is fixed with the clamp that is used for fixing a position patient's head on horizontal straight line actuating mechanism's the removal portion.

Specifically, horizontal linear drive mechanism comprises ball screw pair, cylinder body and slide, and the slide sliding fit is connected on the cylinder body, and ball screw pair's lead screw rotates to be connected in the cylinder body, and ball nut of ball screw pair fixes on the slide, and the slide passes through support fixed connection on the clamp.

Specifically, a rotating handle is fixed at the end of a screw rod of the ball screw pair.

Specifically, the clamp is formed by fixedly connecting an upper semicircular ring and a lower semicircular ring which are symmetrical through a bolt and a nut.

Specifically, be fixed with the elastic layer on the inner circle wall of clamp, evenly distributed has the arc arch on the elastic layer.

The utility model has the advantages that: the utility model provides a head fixing device of embolectomy is got to blood vessel of brain supports patient's head through the pillow support, fixes patient's head through the clamp that can adjust, adjusts the interval between clamp and the pillow support with the straight line actuating mechanism of water. Thereby enabling the patient's head to remain stationary.

In the figure, 1, a pillow support, 2, a fixing plate, 3, a hoop, 4, a horizontal linear driving mechanism, 5, an elastic layer, 41, a ball screw pair, 42, a cylinder body, 43, a sliding seat and 44, a rotating handle are arranged.

Detailed Description

the present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is a front view of the present invention, and fig. 2 is a right side view of the present invention.

The utility model provides a head fixing device of embolectomy is got to blood vessel of brain, includes pillow support 1, fixed plate 2, clamp 3 and horizontal linear drive mechanism 4 and constitutes, set up the arc wall of placing patient's head on the pillow support 1, the cylinder body of horizontal linear drive mechanism 4 is fixed at fixed plate 2 sides, and fixed plate 2 is fixed in pillow support 1 bottom, is fixed with clamp 3 that is used for fixing a position patient's head in horizontal linear drive mechanism 4's the removal portion. The horizontal linear driving mechanism 4 is composed of a ball screw pair 41, a cylinder 42 and a sliding seat 43, the sliding seat 43 is connected to the cylinder 42 in a sliding mode, a screw of the ball screw pair 41 is connected to the cylinder 42 in a rotating mode, a ball nut of the ball screw pair 41 is fixed to the sliding seat 43, and the sliding seat 43 is fixedly connected to the hoop 3 through a support. A rotating handle 44 is fixed at the end of the ball screw pair 41. The clamp 3 is formed by fixedly connecting an upper semicircular ring and a lower semicircular ring which are symmetrical through a bolt and a nut. An elastic layer 5 is fixed on the inner ring wall of the hoop 3, and arc-shaped bulges are uniformly distributed on the elastic layer.

The horizontal linear driving mechanism works in the following way as shown in the attached drawings 1 and 2: the rotating plate 44 is held to rotate, so that the screw of the ball screw pair 41 is driven to synchronously rotate in the cylinder 42. The screw rod can drive the ball nut in threaded connection with the screw rod while rotating, and the ball nut moves along the screw rod. The inner race of the ball nut is threaded onto the lead screw and the outer race of the ball nut is fixed to the slide carriage 43 so that when the lead screw is rotated, the slide carriage 43 is driven to move linearly along the cylinder 42.

Firstly, the fixing plate 2 is fixed on the bed, and then the part of the back of the patient, which is close to the neck, is padded in the arc-shaped groove of the pillow support 1. Then, after the clamp 3 is horizontally moved to a proper position by the horizontal linear driving mechanism 4, the part of the back head of the patient close to the top of the head is placed between the upper semicircular ring and the lower semicircular ring of the clamp 3. After the two semicircular rings are fixed on the head of a patient, the threaded holes at the two ends of the two semicircular rings are screwed in by using bolts, and then nuts are screwed in the bolts to realize the fixed connection of the two semicircular rings. Because the two semicircular rings are connected by the bolts, the two semicircular rings can be matched with different head circumferences and then fixed.

While the elastic layer 5 with the arc-shaped protrusions is directly attached to the head of the patient. The 5 materials of elastic layer are rubber or silica gel, so not only can avoid 3 scotch patients of clamp, and can improve the frictional force with patient's head, avoid the slippage.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
