Head protecting frame used for prone position operations and capable of preventing pressure ulcers

Abstract

A head protecting frame used for prone position operations and capable of preventing pressure ulcers comprises a head support frame, a mirror surface base, a face gel combined support pillow and a lifting adjusting device, wherein a pillow interior storage cavity is defined by a head top limiting flange, face limiting flanges, a lower jaw limiting flange and the bottom of the head support frame; a lower jaw avoiding notch is formed in the center of the lower jaw limiting flange, a five-sense-organ part avoiding opening is formed in the bottom of the pillow interior storage cavity, and an inner limiting flange is arranged on the periphery of the five-sense-organ part avoiding opening; the face gel combined support pillow comprises a sponge support die support and a gel face contact layer, and a five-sense-organ avoiding notch is formed in the face gel combined support pillow; the face gel combined support pillow is mounted in the pillow interior storage cavity, the mirror surface base is arranged below the head support frame, and the head support frame and the bottom mirror surface are integrally connected through the lifting adjusting device. The head protecting frame not only can protect the face of a patient from extrusion to facilitate observation of a doctor, but also can be adjusted freely in height, and the best operation position of the patient is guaranteed.

Description

technical field [0001] The invention relates to a medical device used in clinical operations, in particular to a head operation protection frame for a patient who needs to operate in a prone position. Background technique [0002] When the prone position is required for cervical spine surgery, etc., the placement of the head and face in the prone position is the key and difficult point. When the patient lies down with the face facing down, it is necessary to ensure that the patient's cervical spine is in a normal physiological curve. Avoid hyperextension and bending of the neck, and forehead compression will not cause optic nerve damage. During the operation, the head and face must be seated in the head surgical protection frame. The head and face must be stable and firm, and the eyes, nose and mouth of the person must not be oppressed. Changes during the anesthesia process. During the operation, the patient's face was pressed down for a long time. After the patient was ane...

Problems solved by technology

Due to the use of the sponge support block 2 as the support body of the patient's face, everyone knows that the sponge is a chemical thermal insulation material with good elasticity and soft texture, but when the patient's face is pressed by it for a long time The ventilation and heat dissipation performance of the skin will continue to deteriorate, and the water vapor produced by the human body's metabolism cannot be smoothly discharged through the skin, which can easily cause facial overheating and swelling, and in severe cases, pressure sores and ulcers

Due to the weak constitution and low resistance of patients, many patients are allergic to chemical sponges, so sponges are not suitable as support pads 2

In addition, the height of the head protection frame described in this patent is fixed and cannot be adjusted, because different patients have different body shapes, fat, thin, and tall. The cervical spine is in a normal physiological curve, which makes the patient's neck hyperextended or hyperflexed, which cannot meet the doctor's optimal surgical posture requirements

[0005] At present, people begin to use gel as a head pad for prone position surgery. Because the gel has excellent flexibility, air permeability and thermal conductivity, the flexibility of the gel is similar to people's flesh, and its air permeability and thermal conductivity are very similar to people's skin. Therefore, it is very suitable to use gel as the head pad for prone position operation, but the molding strength of the gel is too low, it is easy to deform, and the stable curing performance is too poor. Therefore, the existing gel prone position operation head protection frame pad It is designed as a V-shaped gel support block with a solidified bottom plate at the bottom to ensure the bottom support area of ​​the gel block. In order to overcome the shortcomings of the flexible gel block that is not easy to solidify and form, and the rigidity is low, people put the V-shaped gel support block on the outside Vacuum wrapping and fixation with medical film is used to improve the rigidity of the head protection frame in the gel prone position operation. Even so, the support rigidity of the V-shaped gel support block is still not ideal. During the operation, the head cannot be accurately limited, and the human body After being stressed, it is easy to shake in the length direction of the human body, so that the accuracy of the operation cannot be precisely controlled, and the size of the surgical incision will be affected in the slightest, and accidental damage to the non-surgical parts will occur in severe cases, such as accidentally cutting off the patient's nerves, human arteries or blood vessels. Serious surgical errors in other important parts will directly threaten the life of the patient and cause medical disputes which cannot be dealt with. The gel support block is vacuum wrapped and fixed, and the patient's face is in contact with the medical film. The air permeability and thermal conductivity of the medical film are extremely poor, so that the air permeability and thermal conductivity of the gel cannot be utilized, and its use effect is not as good as that of the sponge support block. In addition, the bottom of the existing gel protective frame for prone position surgery cannot be equipped with an observation mirror, and the medical staff cannot observe the changes of the patient's face during the operation, which cannot meet the doctor's requirements

[0006] To sum up, none of the existing head protection frames for prone position surgery can ideally meet the position requirements of the patient for prone position surgery
