How much do you know about gel positioning pads?

Gel Surgical Positioning Pad A necessary surgical aid in the operating room, placed under the patient to alleviate pressure sores (bedsores) caused by prolonged surgery. Made of polymer gel and film, it has good softness and pressure-reducing shock absorption, maximizing pressure dispersion and minimizing the occurrence of bedsores and nerve compression injuries. It is X-ray permeable, waterproof, and electrically insulating. The material is latex-free and plasticizer-free, resistant to bacterial growth and non-allergenic. It can withstand temperatures from -18°C to +55°C. It is easy to clean and can be disinfected with operating room-specific non-corrosive disinfectants. Steam sterilization and high-temperature high-pressure sterilization are strictly prohibited. The polymer gel positioning pad is designed and manufactured using special medical materials according to human body shape and surgical angles, allowing for more complete fixation of the patient's position and achieving ideal surgical results. The gel material effectively relieves pressure pain, disperses pressure points, reduces compression injuries to muscles and nerves, and prevents bedsores. Using imported raw materials, the gel has undergone non-toxic, non-irritating, and non-allergenic testing and will not cause any harm to the patient's skin; the injection molding production technology (i.e., the gel is injected through a 1-2cm injection port) results in a small sealing area, making it less prone to bursting or splitting, extending its service life and offering high cost-effectiveness. Contraindications: 1) Not for use on body surface injuries requiring breathability; 2) Not for use on patients with contact allergies to polyurethane materials; 3) Not for use on extremely obese patients requiring prone position surgery. Supine Position Surgical Solutions Mainly divided into horizontal supine, lateral head supine, and head-down supine positions. The horizontal supine position is commonly used in surgeries of the anterior chest wall and abdomen; the lateral head supine position is commonly used in unilateral head and neck surgeries, such as unilateral neck or submandibular gland surgeries; the head-down supine position is commonly used in thyroid and tracheotomy surgeries. This surgical positioning pad mainly has two combination schemes: the first is a circular head ring, upper limb concave positioning pad, shoulder pad, semicircular pad, and heel pad; the second is a sandbag, circular pillow, shoulder pad, buttock pad, semicircular pad, and heel pad. Prone Position Surgical Solutions Commonly used in surgeries such as vertebral fracture fixation and back and spinal deformity correction. This surgical positioning pad mainly has three combination schemes: the first is a high-bowl head ring, chest pad, iliac crest pad, concave positioning pad, and prone leg pad; the second is a high-bowl head ring, chest pad, iliac crest pad, and improved leg pad; the third is a high-bowl head ring, adjustable prone pad, and improved leg pad. Lateral Position Surgical Solutions Commonly used in craniotomy and thoracic surgery. This surgical positioning pad mainly has two combination schemes: the first is a high-bowl head ring, shoulder pad, upper limb concave positioning pad, and tunnel pad; the second is a high-bowl head ring, shoulder pad, upper limb concave positioning pad, leg pad, forearm fixation strap, and hip joint fixation strap. The lateral position is commonly used in craniotomy and thoracic surgery. Lateral Position Surgical Solutions Commonly used in craniotomy and thoracic surgery. This surgical positioning pad mainly has two combination schemes: the first is a high-bowl head ring, shoulder pad, upper limb concave positioning pad, and tunnel pad; the second is a high-bowl head ring, shoulder pad, upper limb concave positioning pad, leg pad, forearm fixation strap, and hip joint fixation strap. The lateral position is commonly used in craniotomy and thoracic surgery. Lithotomy Position Surgical Solutions Usually used in surgeries of the rectum, perineum, and vagina. This surgical positioning pad has only one combination scheme: a high-bowl head ring, upper limb concave positioning pad, buttock pad, and memory foam square pad.

How much do you know about the automatic protection of mobile cylinders?

Electric surgical beds are now widely used because they are convenient for doctors and ensure patient comfort. Below, I will introduce its automatic protection function of the moving cylinder. At present, the shortcomings of the existing technology of electric surgical beds are proposed. A hinge mechanism for the bed pad translation component is used, which uses a hydraulic cylinder and an electromechanical hydraulic surgical table device. In an electric hydraulic surgical table translation device, through a shift cylinder, hip plate seat and connecting mechanism, it is characterized in that the shift cylinder is a double-acting telescopic two cylinders, and the cylinder base is connected to the connecting rod end cylinder front end through a universal joint and connected to the hip plate seat. The translation is generated by the hydraulic cylinder piston chamber, piston rod, and piston rod end connected to the driven disc seat hip to generate displacement parallel to the surgical table to achieve parallel hip plate movement; when the pressure oil chamber of the piston of the connecting rod cylinder, the piston rod retracts, conversely, the hip plate controls the translation piston chamber and the piston rod cylinder pressure oil chamber through the starting position of this sequence, and the parallel movement of the hip plate position can be realized, eliminating human labor, improving the level of mechanization and automation, and being conducive to the control system of the automatic protection function. In a specific implementation scheme, an electric hydraulic surgical table translation device, a shift cylinder, a hip plate seat, and a connecting mechanism are characterized in that the shift cylinder is a double-acting hydraulic cylinder that can be extended and retracted. The cylinder is connected to the front end of the hip plate seat through the piston rod end. The translation is generated by the hydraulic cylinder piston chamber, piston rod, and piston rod end connected to the driven disc seat hip to generate displacement parallel to the surgical table to achieve parallel hip plate movement; when the pressure oil chamber of the piston of the connecting rod cylinder, the piston rod retracts, conversely, the hip plate controls the translation piston chamber and the piston rod cylinder pressure oil chamber through the starting position of this sequence, and the parallel movement of the hip plate position can be realized.
