The invention provides a positioning bracket applied to head treatment, which comprises a fixed frame, wherein the fixed frame comprises at least two vertical branches, and the upper ends of the vertical branches are connected with two transverse branches and two slide way rods;

a moving frame is arranged above the fixed frame and comprises two vertical moving rods and a transverse moving rod connected to the upper ends of the two vertical moving rods; the two vertical moving rods are perpendicular to the slide way rod;

the transverse moving rod is provided with a notch;

and a scale rod is vertically arranged above the transverse moving rod, and scales are marked on the scale rod.

Further, the lower end of the vertical moving rod is connected with a sleeve ring, the slideway rod is sleeved in the slideway rod in a penetrating mode, and the vertical moving rod moves back and forth along the slideway rod.

Further, a telescopic rod is connected between the transverse moving rod and at least one transverse branch.

Further, the slideway rod is provided with an ear clamping piece towards the inner side direction; scales are arranged on the slide way rod.

Furthermore, a positioning part which moves up and down is sleeved on the scale rod.

Furthermore, the lower end of the vertical branch is provided with a height adjusting accessory.

The positioning bracket comprises a fixed bracket and a movable bracket, wherein two slideway rods are arranged on the fixed bracket; a scale rod is arranged above the movable frame, and scales are marked on the scale rod; in the use process, after a target point in the head of a human body is determined, the distance between the target point and the center point of the head of the human body is obtained, then the distance between the center point of the head and the support of the moving frame is calculated, and then the position on the scale rod can be determined, and when the cannula is needed, the tube can simultaneously penetrate through the scale and the notch on the moving rod at the position on the scale rod, and then the tube can be accurately inserted into the position of the target point of the head; therefore, the positioning frame is simple to operate, accurate in positioning and high in practicability.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic structural view of a positioning bracket for head treatment according to the present invention; fig. 2 is a schematic diagram of a blasting structure of a positioning bracket for head treatment according to the present invention; the positioning bracket comprises a fixed frame, wherein the fixed frame comprises at least two vertical branches 11, preferably four vertical branches, and the upper ends of the vertical branches 11 are connected with two transverse branches 13 and two slide way rods 12; forming a shelf similar to a table structure.

A moving frame is arranged above the fixed frame and comprises two vertical moving rods 21 and a transverse moving rod 22 connected to the upper ends of the two vertical moving rods 21; the two vertical moving rods 21 are perpendicular to the slideway rod 12;

the transverse moving rod 22 is provided with a notch 221; a scale rod 24 is vertically arranged above the transverse moving rod 22, and scales are marked on the scale rod 24.

FIG. 3 is a schematic view of the present invention in various positions during use; FIG. 4 is a schematic diagram showing the distance between the positions of the present invention during use; when the positioning frame is used, the head of a human body is placed above the fixing frame; illustratively, the slideway rod is provided with an ear fastener 25 towards the inner side; simultaneously, after for human head installation, the ear of the human both sides of being convenient for is aimed at, be equipped with the scale on the slide pole.

A in FIG. 3 is the forehead of the human head; b is a tube needing to be intubated; the position A1 is a human head target point determined by CT scanning, and the position A2 is the center point of the head on the horizontal plane where the human head target point is located; when the target point is determined, it is necessary to insert tube B from above the forehead surface A of the head to point A1.

In the invention, the head or the support is moved, so that the vertical plane where the head target point A1 is located coincides with the vertical plane of the moving frame. Since A2 is at the level of the target point on the head of the human body, the center point of the head, which is also aligned with the center point of the lateral travel bar 22.

Denoted by a, the distance between a2 and the transverse bar 22 is denoted by b, and the distance between the transverse bar 22 and the notch is denoted by c; the distance between the point of the graduated rod where the tube is inserted downwards and the transverse displacement rod 22 is indicated by x.

Since the distance a between a1 and a2 is known from CT scan and known after a2 point scan, the distance a2 to the frontal plane of the head is known and measured by CT from the center point between the frontal plane of the head and the transverse travel bar 22, i.e., b is also known; the distance b from the center point A2 of the head to the center point of the transverse moving rod 22 can be directly measured by an instrument; the distance between the transverse travel bar 22 and the gap is measurable as c, known; therefore, the value of x can be calculated according to a, b and c; the positioning point of the required cannula on the scale rod can be obtained.

In order to facilitate adjustment, a vertical plane where the target point of the head of the a1 is located is made to coincide with a plane of the moving frame in the vertical direction, in the invention, the coincidence can be adjusted by moving the head, or can be adjusted by adjusting the moving frame, illustratively, the lower end of the vertical moving rod 21 is connected with a lantern ring, the chute rod is sleeved in the chute rod 12, and the vertical moving rod 21 moves back and forth along the chute rod 12; by moving the two vertical movement bars 21, the adjustment is preferably carried out,

an expansion link 23 is connected between the transverse moving rod 22 and at least one transverse branch 13 for supporting the moving frame.

In the invention, the positioning part 3 which moves up and down is sleeved on the scale rod 24. After the value of x is calculated, the positioning member 3 is moved to the scale of the value, namely the positioning position, the pipe passes through the positioning position and the notch on the transverse moving rod simultaneously, two points determine a line, and the pipe can be positioned to the target point A1.

In order to adjust the height of the positioning frame, the lower end of the vertical branch 11 is provided with a height adjusting fitting 111, for example, a screw is mounted at the lower end of the vertical branch 11, and the height can be adjusted by screwing the screw.

The above description is only exemplary of the present invention and should not be taken as limiting the invention, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
