Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a head fixation device for medical beach chair positions. Background Technology

[0002] During surgery, some patients require proper restraint with appropriate tightness (enough to accommodate one finger) to maintain stable positioning and prevent displacement or falls. During positioning, proper immobilization and warmth should be ensured, maintaining the patient's dignity and privacy while minimizing impact on physiological function and fully exposing the surgical field. Clinically, patients undergoing shoulder joint surgery for rotator cuff injuries are often positioned supine in a beach chair position, with their back at a 60-70° angle to the horizontal on the operating table. After general anesthesia, tape, bandages, skin films, or specialized head immobilization devices are used to stabilize the head and prevent neck movement. However, adhesive residue from traditional tape is difficult to remove, especially from the face and hair, which can cause allergies. Jaw immobilization is unstable, and rigid materials can cause pressure injuries. Post-anesthesia changes in surgical position affect the surgical field, necessitating position adjustments during surgery. Tape restraint for head immobilization is unstable and carries the risk of tracheal dislodgement and cervical spine injury. Utility Model Content

[0003] The purpose of this invention is to provide a head fixation device for medical beach chair positions, in order to solve the problems of the lack of a highly compatible fixation device during the above-mentioned treatment process, the non-standard positioning of the body, and the possibility of nerve and muscle damage when fixing the head, thereby shortening the operation time and improving work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a head fixation device for a medical beach chair, comprising a forehead restraint strap and a chin restraint strap, wherein the forehead restraint strap and the chin restraint strap are filled with cushioning material to prevent pressure injury to the patient, and the chin restraint strap and the forehead restraint strap are connected by two sets of sliding connection mechanisms, and the ends of the forehead restraint strap are provided with a first fixing mechanism, which allows the two ends of the forehead restraint strap to be detachably fixed to the beach chair, and the chin restraint strap is provided with a locking mechanism, which fixes it to the beach chair.

[0005] The mandibular restriction band has a mandibular opening in the middle for positioning and restriction at the patient's mandible.

[0006] The first fixing mechanism includes a first Velcro fastener fixed to one end of the forehead restraint and a second Velcro fastener fixed to the other end of the forehead restraint. The first and second Velcro fasteners are connected and fixed together. The locking mechanism includes two ends of the chin restraint, which are detachably fixed to the bottom of the beach chair.

[0007] The sliding connection mechanism includes two clips fixed on both sides of the middle of the forehead restriction band, with a gap between the clips and the forehead restriction band, and the two ends of the chin restriction band passing through the gap between the two clips and the forehead restriction band respectively.

The two ends of the chin restraint band 2 are fixed to the crossbar under the beach chair by a binding method. Example

[0037] like Figure 3 , Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the first fixing mechanism includes a fixing buckle fixed to one end of the forehead restriction band 1 and a fixing strap 105 fixed to the other end of the forehead restriction band 1. The fixing strap 105 is detachably fixed to the fixing buckle and is used to fix the forehead restriction band 1.

[0038] In this embodiment, the fixing buckle includes a retaining ring 104 fixed to one end of the forehead restraint band 1. A retaining pin 106 is provided in the middle of the retaining ring 104. One end of the retaining pin 106 is rotatably connected to the retaining ring 104, and the other end of the retaining pin 106 rests on the retaining ring 104. The middle of the fixing band 105 is provided with a plurality of holes 107 for passing through the retaining pin 106. The distance between two adjacent holes 107 is 1mm. The two ends of the forehead restraint band 1 are fixed by the retaining pin 106 and the holes 107, forming a structure similar to a belt buckle. Example

[0039] The difference between this embodiment and embodiment two is that there is a 5mm gap between two adjacent card holes 107, which is used to accommodate the head fixation of different patients. Example

[0040] like Figures 5-9 As shown, the difference between this embodiment and embodiment two is that the fixed buckle includes a slide groove 108 fixed to one end of the forehead restraint band 1. A rotating post 109 is rotatably provided on one side of the slide groove 108. One end of the rotating post 109 passes through the slide groove 108 and is fixed with a lever 112. A card 110 is fixed on the rotating post 109. A torsion spring 111 is sleeved on the rotating post 109. One end of the torsion spring 111 is locked at the upper end of the slide groove 108, and the other end is locked on the card 110, pressing the card downward.

[0041] The upper side of the fixing strap 105 is fixed with a row of evenly distributed inclined slots 113. The inclined slots 113 are right-angled triangular prisms with their inclined surfaces facing upwards and towards the ends. The fixing strap 105 passes through the slide groove 108. The end of the card 110 is pressed against the inclined slot 113 under the action of the torsion spring, thus forming a structure similar to a belt buckle, which is used to fix the forehead restraint strap 1. When loosened, by moving the lever 112, the card 110 is moved away from the inclined slot 113, thereby loosening the fixing strap 105 and removing the fixing strap 105 from the slide groove 108. Example
