Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The present invention will be further described with reference to the following examples.
Examples
A head fixing device for neurosurgery of the present embodiment, with reference to fig. 1 to 6: comprises a mounting plate 1 and a head fixer; the head fixer also comprises an arc-shaped sliding rail 6, three positioning rods and three sliding pieces 16; the arc-shaped sliding rail 6 is connected with the sliding part 16 in a sliding manner through the arc-shaped through groove 21 on the sliding part 16, so that the sliding part 16 can slide along the arc-shaped sliding rail 6 in the circumferential direction without hindrance, the sliding part 16 is provided with a radial thread groove 20 matched with the positioning rod, and the positioning rod passes through the radial thread groove 20 and is fixed on the sliding part 16; the bottom of the arc-shaped slide rail 6 is fixed on the mounting plate 1 through the substrate mounting part 18, so that the mounting plate 1 and the arc-shaped slide rail 6 are detachably mounted together, and medical staff can conveniently clean and disinfect the arc-shaped slide rail, a support holder 7 is further fixed on the arc-shaped slide rail 6 close to the inner side of the bottom, wherein the height of the support holder 7 is 1/3 of the radius of the arc-shaped slide rail 6, so that the head of a patient can keep a certain distance from the arc-shaped slide rail 6 when being fixed, and meanwhile, the observation and operation of a doctor in an operation are facilitated; the locating rod includes screw rod 13, runner 14 and splint, and runner 14 establishes at the top of screw rod 13 and rotates runner 14 and just can let screw rod 13 also rotate, and splint establish in the bottom of screw rod 13 and splint are used for supporting patient's head.
Because the neck of the patient is in a suspended state after the head of the patient is fixed, if the neck of the patient is suspended for a long time, the postoperative feeling of the patient is affected, the U-shaped neck support 4 matched with the head fixer is further arranged on the mounting plate 1 to support the suspended neck of the patient in the operation, and meanwhile, the U-shaped neck support 4 can also play an auxiliary role in fixing the head of the patient; the top of U type neck brace 4 is equipped with the inner groovy, is equipped with assorted gasbag 3 and gasbag 3 in the inner groovy and meets with aerifing handball 17 through air duct 2, thereby the reason of design like this is that every patient's size is not necessarily the same thereby causes the space also different between neck and mounting panel 1, inflates gasbag 3 through pressing and aerifing handball 17 and makes it swell to suitable size and support patient's neck.
The track of the arc-shaped slide rail 6 is an arc-shaped through sliding groove 9 formed in the middle of the arc-shaped side wall of the circular ring body, so that the arc-shaped slide rail 6 has double tracks, and compared with a single track, the double tracks can enable the sliding part 16 to have better stability after being installed; because the back head of the patient is the key part for fixing the whole head when the patient is in the supine position in the operation, the supporting bracket 7 for fixing and supporting the back head of the patient is larger than other splints, and the angle range of the arc through groove 21 is 180-280 degrees; support and hold in the palm 7 for the arc splint and support the top that holds in the palm 7 and be equipped with assorted flexible pad body 8, the flexible pad body 8 can make the skin tissue of its back brain spoon department can not receive the excessive extrusion injury of rigid splint when patient's head is fixed.
The screw 13 passes through the radial screw groove 20 and is fixed on the sliding part 16, so that the screw 13 can move on the sliding part 16 in a radial direction through clockwise or anticlockwise rotation; be equipped with spacing arch 22 and spread groove 25 near the bottom of screw rod 13, be equipped with ladder groove 23 on the splint, the bottom of screw rod 13 is through passing ladder groove 23, wherein spacing portion blocks into in the upper groove of ladder groove 23, the spread groove 25 and the mounting 19 of screw rod 13 bottom are connected and the mounting 19 blocks into the lower groove of ladder groove 23, make splint by the centre gripping between spacing arch 22 and the mounting 19 of screw rod 13 bottom, this is because when fixing patient's head with the locating lever, screw rod 13 is the screw propulsion formula motion in radial direction, in order not to make splint follow screw rod 13 and rotate and cause the injury to patient's head, just must guarantee that the rotation of screw rod 13 only has radial power and the power of rotation direction to the splint.
The splints include a first arc splint 11, a second rectangular splint 10 and a third rectangular splint 12, because the congenital shape of the skull of a person is roughly symmetrical arc-shaped for the forehead and the back of the brain, and the two sides of the cheek are horizontal, so when in installation, the first arc splint 11 is arranged between the second rectangular splint 10 and the third rectangular splint 12, and the head of a patient changes shape due to acquired reasons, and the splints can support and fix the head of the patient by moving the sliding part 16 to find a proper angle; meanwhile, the splint is made of hard metal or alloy, and the surface of the splint is glued with a layer of flexible pad body 8, so that the splint can protect the head tissue at the fixed position when fixing the head of a patient.
Both sides of the sliding part 16 are provided with brake grooves 24, and the matched brake parts 15 are screwed in through the brake grooves 24, so that the sliding part 16 is reliably fixed on the arc-shaped sliding rail 6, the sliding part 16 can slide to any proper position and be fixed, and the positioning rod can search for a proper angle to push the clamping plate to support and fix the head of a patient.
When the device is used, a doctor can mount the device on an operating table or matched equipment through the preformed groove 5 as required, so that a patient lies on the operating table in a supine posture, then the patient stretches the head into the head fixer, the back head of the patient is placed on the supporting support 7, and the inflatable ball is pressed to inflate the air bag 3 so as to well support the neck of the patient; according to the actual shape of the head of a patient, three sliding parts 16 are sequentially adjusted to reach proper positions on the arc-shaped sliding rail 6, the braking parts 15 on the two sides of each sliding part 16 are rotated to fix the sliding parts 16, then the rotating wheels 14 on the positioning rods are sequentially rotated to adjust the screw rods 13 to be pushed to the proper positions in the radial direction, and meanwhile, when the splint is in contact with the head of the patient, the other hand of a doctor needs to hold the splint, so that the splint is in good contact with the head of the patient; it is noted that when the doctor finds the proper position on the adjustment slider 16 and adjusts the amount of rotational advancement of the screw 13, the doctor can communicate with the patient in the non-anesthetized state, thereby quickly and accurately fixing the head of the patient.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
