[0002] Posterior fossa surgery is an important procedure in neurosurgery, involving the anatomical structure of the posterior fossa and related diseases. Located at the back of the skull, the posterior fossa contains important structures such as the brainstem, cerebellum, and hypocranial nerves. Its complex anatomy makes surgery challenging and high-risk. Postoperatively, the surgical area must be kept free of pressure to prevent adverse effects on recovery.

[0003] Chinese patent document CN219579295U discloses a decompression pillow for posterior fossa surgery. This decompression pillow aims to solve the technical problem in existing technologies that make it difficult to prevent pressure on the surgical site and drainage tubes during bed rest after posterior fossa surgery, easily increasing the occurrence of pressure ulcers and affecting wound healing. It includes a decompression pillow body with a posterior fossa suspension section at the center of its top. Lateral depressions are provided on both sides of the top of the decompression pillow body, located in front of the posterior fossa suspension section. A neck support section is located between the neck support section and the posterior fossa suspension section. Three sets of placement grooves are symmetrically formed inside the left and right sides of the decompression pillow body. This utility model solves the technical problem of pressure on the surgical site and drainage tubes during bed rest after posterior fossa surgery, preventing pressure ulcers and facilitating wound healing.

[0004] The existing technology has the following problems: This pressure-reducing pillow only provides neck support, leaving the patient's head unsupported. This lack of head support results in significant pressure on the neck, affecting the patient's rest. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-5 As shown, a device for decompression of the surgical area after neurosurgical posterior fossa surgery includes a base plate 1, a pillow pad 2 fixedly connected to the upper side of the base plate 1, a suspended notch 3 opened on the front side of the pillow pad 2, and two sliding tubes 4 distributed on the left and right sides fixedly connected to the upper side of the base plate 1. A neck support mechanism 5 is movably sleeved on the inner side of the sliding tubes 4. The neck support mechanism 5 includes a base plate 51, a plurality of horizontally distributed airbags 52 are fixedly connected to the upper side of the base plate 51, an elastic pad 53 is fixedly connected to the upper side of the base plate 51, and the airbags 52 are located inside the elastic pad 53. Two electrically controlled valves 54 are fixedly connected to the upper side of the base plate 51.

[0019] It should be noted that the upper side of the base plate 1 is wavy with a concave middle. The suspended notch 3 is used to place the surgical incision site for the posterior cranial fossa. Since the posterior cranial fossa is located on the lower side of the back of the head, a pillow pad 2 can be used to support the back of the patient's head. The electrically controlled valve 54 is connected to the airbag 52 through a hose. The electrically controlled valve 54 is connected to an external air pump to inflate the airbag 52, thereby adjusting the height of the upper side of the elastic pad 53 so that the elastic pad 53 supports the patient's neck.

[0020] like Figure 3 As shown, the two outermost airbags 52 are interconnected, and the several inner airbags 52 are interconnected.

[0021] It should be noted that the middle airbag 52 is not connected to the outer airbag 52, so that the outer airbag 52 can be slightly higher than the middle airbag 52 after ventilation, thereby adapting to the patient's neck curve.

[0022] like Figure 2 , Figure 3 As shown, a mounting tube 55 is fixedly connected to the upper middle part of the base plate 1, and a telescopic rod 56 is movably sleeved on the inner side of the mounting tube 55. The front side of the telescopic rod 56 is fixedly connected to the rear side of the base plate 51.

[0023] It should be noted that the telescopic rod 56 is an electric push rod that can drive the base plate 51 to move back and forth.

[0024] like Figure 3 As shown, a telescopic sleeve 57 is fixedly sleeved on the outer side of the telescopic rod 56 near the front side.

[0025] It should be noted that the telescopic sleeve 57 is used to protect the moving parts on the telescopic rod 56 and the parts exposed on the outside of the placement tube 55, so as to prevent the patient's dandruff, hair, medicine and other debris from falling on the telescopic rod 56 and being difficult to clean.

[0026] like Figure 3 As shown, the outer side of the telescopic sleeve 57 is coated with Teflon.

[0027] It should be noted that the Teflon coating improves the wear resistance of the telescopic sleeve 57, and at the same time, it has oil-transfer properties, making it easy to clean the telescopic sleeve 57.

[0028] like Figure 4 As shown, a fixing pipe 58 is fixedly connected to the upper side of the base plate 1 near the rear side, and a fixing column 59 is fixedly connected to the rear side of the telescopic rod 56. The outer side of the fixing column 59 is movably sleeved on the inner side of the fixing pipe 58.

[0029] It should be noted that both the fixing post 59 and the fixing tube 58 are provided with fixing holes, which can be used to fix the fixing post 59 and the fixing tube 58 with screws or pins. The telescopic rod 56 is provided with a tapered rubber sleeve on the outside, which not only avoids the gap between the telescopic rod 56 and the mounting tube 55, but also reduces the wear of the parts caused by the movement of the telescopic rod 56 and the mounting tube 55.

[0030] like Figure 5 As shown, two limiting rods 510 distributed on the left and right are fixedly connected to the upper side of the substrate 51, and the outer side of the limiting rod 510 is movably sleeved on the inner side of the slide tube 4.

[0031] It should be noted that the limiting rod 510 is used to stabilize the movement of the substrate 51, so that the substrate 51 can only move back and forth, while preventing the connection between the substrate 51 and the telescopic rod 56 from breaking due to lateral torsion.

[0032] The working principle of this utility model is as follows: First, the upper side of the base plate 1 is wavy with a concave middle. The suspended notch 3 is used to place the surgical incision position for the posterior cranial fossa. Since the posterior cranial fossa is located on the lower side of the back of the head, a pillow pad 2 can be used to support the back of the patient's head. The electrically controlled valve 54 is connected to the airbag 52 via a flexible hose. The electrically controlled valve 54 is connected to an external air pump to inflate the airbag 52, thereby adjusting the height of the upper side of the elastic pad 53 so that the elastic pad 53 supports the patient's neck. The middle airbag 52 is not connected to the outer airbag 52, so that the outer airbag 52 can be slightly higher than the middle airbag 52 after inflation, thus adapting to the patient's neck curve. The telescopic rod 56 is an electric push rod that can drive the base plate 51 to move back and forth. By moving the base plate 51 back and forth through the telescopic rod 56, the distance between the elastic pad 53 and the pillow pad 2 can be adjusted to accommodate patients with different neck lengths, so that the pillow pad 2 and the elastic pad 53 jointly support the patient's head and neck, avoiding support only for the neck. This design avoids excessive pressure on the patient's neck, is easy to operate and adjust. Finally, the telescopic sleeve 57 protects the moving parts on the telescopic rod 56 and the exposed parts on the outside of the placement tube 55, preventing various debris such as dandruff, hair, and medication from falling onto the telescopic rod 56 and being difficult to clean. Both the fixing post 59 and the fixing tube 58 are provided with fixing holes, which can be fixed between the fixing post 59 and the fixing tube 58 by screws or pins. The outside of the telescopic rod 56 is provided with a conical rubber sleeve, which not only avoids gaps between the telescopic rod 56 and the placement tube 55, but also reduces wear on the parts caused by movement. The telescopic sleeve 57 protects the telescopic rod 56, preventing possible debris such as dandruff and medication from falling onto the telescopic rod 56 and being difficult to clean. By fixing the fixing tube 58 and the fixing post 59 with screws or pins, the base plate 1 and the neck support mechanism 5 can be quickly separated, thus facilitating the maintenance of the pillow 2 and the neck support mechanism 5.
