Description

Technical Field

[0001] This utility model relates to the field of medical tool technology, and in particular to a malleable head fixation device. Background Technology

[0002] Medical snow packs are medical devices primarily used to immobilize patients during surgery. The snow packs are filled with thousands of resin particles. Due to their malleability, medical staff use negative pressure to remove air from the snow packs, shaping them to the desired form and thus immobilizing the patient according to the shape of their head and neck. However, the use of snow packs to immobilize the patient's head presents the following significant problems, which to some extent affect the smooth progress of the surgery:

[0003] 1. Snow pads are often placed directly on the surgical mattress during use. The snow pads themselves lack a fixing mechanism, making it difficult for them to remain stable on the surgical mattress. Moreover, the surgical mattress has a certain degree of elasticity. When the head is placed on the snow pad, the snow pad will sink and cannot provide sufficient support for the head.

[0004] 2. The shape of the existing snow pack pad can easily obscure the patient's face during the process of fixing the patient's head, causing surgical interference. Utility Model Content

[0005] This application provides a malleable head fixation device. When the human head is placed on the snow pack for head wrapping and fixation, the rigidity of the base plate provides sufficient support to stably maintain the head position and prevent the snow pack from sinking due to an overly soft surgical mattress, thus avoiding head displacement. At the same time, the protruding design of the snow pack can better shape and fix the patient's head and neck, avoiding obstruction of the patient's face and affecting the surgical area, thus facilitating surgical operations for medical staff.

[0006] This application provides a malleable head fixation device, including a base plate made of acrylic sheet with a certain rigidity to provide sufficient support for the patient's head. A snow pad is detachably connected to the upper side of the base plate. The snow pad is mainly made of polyurethane that is X-ray transparent and is filled with thousands of resin particles. The snow pad is designed in a protruding shape. When the patient's head is placed on the snow pad, the protruding part on the front can leave space for facial operation while supporting the patient's neck, so as to facilitate the medical staff to perform surgical operations. A connecting tube is connected to the rear side of the snow pad, and a valve is installed on the connecting tube.

[0007] The upper surface of the base plate is glued with Velcro A, and the lower surface of the snow pack pad is glued with Velcro B. Velcro A and Velcro B are glued together, which makes it easy to adjust the position of the snow pack pad on the base plate and to remove and install it later.

[0008] Further, straps are attached to both sides of the base plate.

[0009] A head support pad, which is arranged in a ring shape, is fixedly connected to the bottom surface of the inner side of the snow pad.

[0010] Further head support pads are made of silicone pads with a certain degree of hardness and elasticity.

[0011] One or more technical solutions provided in this application embodiment have at least the following technical effects or advantages: The base plate is placed on the operating table, and the stability of the base plate on the operating table is ensured by tying the straps to the operating table frame. After the snow pad is shaped according to the size of the patient's head (generally an arc shape that wraps around the head), it is fixed to the base plate by Velcro (at this time, the snow pad is in an air-filled state). The patient's head is placed on the upper surface of the snow pad, with the occiput above the head support pad and the neck at the protruding position on the front side of the snow pad. The valve on the connecting pipe is opened and a vacuum pump is used to extract the air from the snow pad, thereby achieving the shaping of the snow pad to firmly wrap and fix the patient's head. The base plate provides sufficient support when the patient's head is placed on the snow pack for wrapping and fixation. This stability helps maintain the head's position and prevents the snow pack from sinking due to a soft surgical mattress, thus avoiding head displacement. The added straps ensure the base plate remains stable on the operating table. Furthermore, the raised bumps on the snow pack help to shape and fix the patient's head and neck, preventing obstruction of the face and ensuring sufficient space for surgical procedures.

[0022] Example 1

[0023] Please see Figure 1-6 A malleable head fixing device includes a base plate 10.

[0024] The upper side of the base plate 10 is detachably connected to a snow pad 20, the main component of which is polyurethane that is X-ray transparent, and the interior is filled with thousands of resin particles. The snow pad 20 is designed in a protruding shape. When the patient's head is placed on the snow pad 20, the protruding part on the front can leave space for facial operation while supporting the patient's neck, so as to facilitate the medical staff to perform surgical operations.

[0025] The upper surface of the base plate 10 is glued with Velcro A side 11, and the lower surface of the snow pad 20 is glued with Velcro B side 21. Velcro A side 11 and Velcro B side 21 are glued to each other, which facilitates the adjustment of the position of the snow pad 20 on the base plate 10 and its subsequent disassembly and assembly.

[0026] The base plate 10 is made of acrylic sheet with a certain degree of hardness. When the human head is placed on the snow pad 20 for head wrapping and fixation, the hardness of the base plate 10 provides sufficient support to stably maintain the position of the head, prevent the snow pad 20 from sinking due to the softness of the surgical mattress, avoid head displacement, and effectively improve the stability of the snow pad 20 when wrapping the head.

[0027] The base plate 10 is secured with straps 12 on both sides. By attaching the straps 12 to the operating table frame, the base plate 10 is placed stably on the operating table, preventing it from shifting.

[0028] A head support pad 23 is fixedly connected to the bottom surface of the snow pad 20. It is designed in a ring shape to support the patient's occipital area, so that the head can be placed stably on the snow pad 20.

[0029] The head support pad 23 is made of silicone with a certain degree of hardness and elasticity. When the air inside the snow pack pad 20 is extracted, the head support pad 23 can help keep the patient's head stable and prevent unnecessary head movement.

[0030] The rear side of the snow pad 20 is connected to a connecting pipe 30, and a valve is installed on the connecting pipe 30. The inflation and deflation of the snow pad 20 are achieved by controlling the valve.

[0031] In actual operation of this embodiment, the base plate 10 is placed on the operating table. The base plate 10 is secured to the operating table frame by the straps 12, thus ensuring its stability on the operating table. The snow pad 20 is shaped according to the size of the patient's head (generally an arc shape that wraps around the head) and fixed to the base plate 10 by Velcro (at this time, the snow pad 20 is in an air-filled state). The patient's head is placed on the snow pad 20, with the occiput above the head support pad 23 and the neck at the protruding position on the front side of the snow pad 20. The valve on the connecting pipe 30 is opened and a vacuum pump is used to extract the air from the snow pad 20, thereby achieving the shaping of the snow pad 20 to securely wrap and fix the patient's head.

[0032] The technical solutions described in the above embodiments of this application have at least the following technical effects or advantages: When the human head is placed on the snow pack pad for head wrapping and fixation, the hardness of the base plate provides sufficient support to stably maintain the head position and prevent the snow pack pad from sinking due to the softness of the surgical mattress, thus avoiding head displacement; the addition of straps ensures the stability of the base plate on the operating table; at the same time, the protruding design of the snow pack pad can better shape and fix the patient's head and neck, avoiding obstruction of the patient's face and affecting the surgical area, leaving facial space to facilitate surgical operations by medical staff.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
