Description

Technical Field

[0001] The invention belongs to the technical field of surgical auxiliary equipment in medical instruments, and in particular relates to a head support device for prone position surgery. Background Art

[0002] At present, surgery has become a relatively common treatment method in clinical practice. During surgery, according to the surgical site and anesthesia plan, the patient needs to adopt a passive lying position such as supine, lateral, prone, lithotomy, etc. Among them, the prone surgery requires the patient to lie face down on the operating table. In order to keep the patient's head position fixed and comfortable, the head and the operating table need to be supported by a cushion. The existing technical solution is to support the head and face by a non-transparent flat base and 4 three-dimensional convex blocks fixed thereon, which are wrapped with leather on the outside and sponge on the inside. Disadvantages: The base of this device is a whole piece of opaque material. The face of the surgical patient in the prone position is embedded between the 4 sponge convex blocks. Medical staff cannot see the patient's complexion, lip color, consciousness, etc., especially patients with tubes (such as endotracheal intubation), which not only affects the observation of the condition, but also limits the direction of the tube. The existing technical solution is not conducive to viewing and observing the patient's face and the surrounding tube conditions, and blocks the smooth flow of the mouth and nose with the outside. The three-dimensional columnar support bumps have different skin comfort and pressure surfaces for different patients. If the operation time is long, the head and face that come into contact with the support device may easily become red, suffer pressure sores, and press on the eyes, which may not be detected in time and cause secondary injury. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a head support device for prone surgery, which solves the problem that it is difficult to observe the patient's facial condition and the surrounding pipeline conditions during prone surgery, and the long intraoperative time can easily cause facial and eye compression and secondary injuries.

[0004] The technical solution adopted by the present invention is: a prone surgical head support device includes a support seat, a head support assembly and a reflector, the support seat is a planar structure with two convex rods on one side, a through hole is processed at the center of the support seat, the contour and position of the through hole match the facial contour of the patient's head when the head is placed on the head support assembly, the convex rod of the support seat is connected to the front end of the operating bed so that the support seat can rotate 0 to 30 degrees around the connection axis and the support seat is fixedly connected to the operating bed at this angle, a slide is installed on the upper surface of the support seat, the head support assembly is installed on the slide, the head support assembly is composed of a top support, a left support and a right support to form an arc shape, the arc opening faces the patient's chin, the reflector is fixed to the lower part of the front end of the operating bed, and medical staff can observe the patient's face and the connection pipelines on the patient's face through the reflector.

[0005] Preferably, an alarm is installed on the edge of the through hole of the support base. The alarm is located at the top and left and right sides of the through hole. It identifies through facial scanning whether the patient's eye position is blocked by the head support assembly. When the eyes are blocked, an alarm is immediately sounded to prevent secondary injury to the face and eyes due to long pressure during surgery.

[0006] Preferably, the top support, left support and right support have the same structure, which are, from bottom to top, a connecting part, a sponge supporting part, an airbag part and a contact part. A slide groove is processed at the bottom of the connecting part, and the slide groove cooperates with the slide to make it move along the slide direction. A locking structure is also provided on the side of the connecting part. When it moves to a suitable position along the slide, the locking structure locks the connecting part and the slide position. The sponge supporting part is a three-dimensional sponge block. The airbag part is located on the upper part of the sponge supporting part. The airbag part includes an outer jacket, filling particles located in the outer jacket, and multiple air columns connected by an airbag tube. The top of the air column is an air hole, and the air column is made of silicone. The other end of the airbag tube is connected to an air supply device, and the air supply device is fixed to the bottom surface of the support seat. The filling particles are soft sponges or foam particles with a supporting function. The contact part is a cloth surface made of antibacterial material attached to the upper part of the outer jacket of the airbag part.

[0007] Preferably, the reflector is a three-fold mirror with upward-tilted magnifying glasses on both sides and a horizontal plane mirror in the middle, which is convenient for observing the patient's complexion, lip color, consciousness and the condition of the patient's surrounding pipes. The reflector is arranged directly below the patient's face and is positioned so as not to interfere with the medical staff's walking and surgical operations.

[0008] Preferably, the air columns of the airbag part are multiple and evenly distributed in the airbag part jacket, and the air is exhausted in sequence and at intervals according to the exhaust scheme set by the air supply device to achieve the function of massaging the face. Specifically, the air columns are grouped into a group and divided into square or circular areas with a side length or diameter of 2 cm according to the overall position. Each area is used as a unit for exhaust, and adjacent areas are cross-exhausted at intervals.

[0009] Preferably, the airbag portion is filled with a Chinese medicine powder package with the function of promoting blood circulation and removing blood stasis, which includes one portion each of angelica, fried pecan kernels, dried motherwort, lycopodii herb, eucommia bark, cyathula officinalis, angelica dahurica, ligusticum chuanxiong, millettia reticulata, and a trace amount of earthworm, which is used to promote blood circulation in the patient's face.

[0010] Preferably, a heating device is installed in the airbag portion, and the heating device is a heating pad for promoting blood circulation in the patient's face.

[0011] The beneficial effects of the present invention are: 1. The entire prone head support device extends out of the head of the operating bed, and the patient's head is supported by a support frame with an inclination and through holes so that the patient's mouth and nose can communicate with the outside world. It is especially more comfortable for patients with nasal catheters, endotracheal cannulas, etc. with tubes on the face and neck, and reduces the patient's pain.

[0012] 2. It is convenient for medical staff to observe the patient's complexion and consciousness as well as the condition of the facial and cervical tubes. Through the reflector, medical staff can directly observe the face and surrounding conditions of the patient in the prone position during surgery.

[0013] 3. For some surgeries performed in the prone position, the operation time is longer. The airbag part of the head support component effectively relieves the pressure on the patient's forehead, cheekbones, auricle and face. It inflates and deflates at intervals according to the operation time, changes the pressure points on the face, as well as the size and position of the pressure points, promotes blood circulation in the compressed part, and prevents the occurrence of redness, pressure sores, eye pressure, etc.

[0014] 4. Prevent the device from exerting pressure on the eyes through an alarm device, and avoid the device from exerting pressure on the eyes for a long time, thereby avoiding secondary injuries such as congestion, swelling, and blindness.

[0015] 5. Promote the patient's facial blood circulation through traditional Chinese medicine and heating devices. BRIEF DESCRIPTION OF THE DRAWINGS
