Description

Technical Field

[0001] This utility model relates to an auxiliary device for use in ophthalmic operating rooms. More specifically, this utility model relates to an ophthalmic surgical head frame. Background Technology

[0002] During ophthalmic surgery, to ensure sterility in the surgical area, sterile drapes are laid during preoperative preparation. These drapes must adequately expose the surgical incision while minimizing the exposure of surrounding skin. Therefore, sterile drapes are placed under the patient's eyes and secured to the head and face with tape to prevent movement or falling. During surgery, when the sterile drape covers the patient's mouth and nose, the patient can easily experience breathing difficulties or even a feeling of suffocation, making the surgery impossible. To address this issue, existing patent (CN213430635U) provides a simple head frame for ophthalmic surgery, comprising a fixed sub-rod and a fixed main rod. A telescopic rod is fixedly connected to the top left side of the fixed sub-rod, and a connecting rod is bolted to the top of the telescopic rod. A sterile drape support rod is bolted to the end of the connecting rod away from the telescopic rod. The sterile drape support rod supports the sterile drape covering the patient's mouth and nose, allowing for unobstructed breathing. However, clinical application has shown that this head frame installation method is cumbersome and cannot guarantee the stability of the sterile drape during surgery. The suffocation sensation was not significantly relieved in most patients. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0024] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0025] like Figure 1 , Figure 2 As shown, this utility model provides an ophthalmic surgical head frame, which includes:

[0026] A facial support cover 100 includes a cover body 101 extending from the patient's neck to the mouth and a nasal wing portion 102 extending from the cover body 101. The cover body 101 supports the surgical drape over the patient's mouth and nose, providing a breathing space and reducing the patient's feeling of suffocation. The nasal wing portion 102 extends to the patient's nose, not only providing breathing space but also fully exposing the surgical field.

[0027] A bottom support 200 is disposed on the bottom edges of both sides of the cover 101; the bottom support 200 is placed on both sides of the patient's head to support the cover 101; the bottom support 200 is, for example, composed of a telescopic rod; for easy storage;

[0028] And a shoulder fixation member 300, which is rotatably connected to the tail end of the bottom support 200, is placed under the patient's shoulder. The shoulder fixation member 300 is rotatably connected to the bottom support 200, for example, by a pin 301, so that when stored, the shoulder fixation member 300 can be rotated inward into the mask to reduce the space occupied.

[0029] like Figure 1 As shown, in one embodiment, the face support cover 100 further includes an arched bracket 103 configured to support at least one arched rod 1031 of the cover body 101. The arched rods 1031 may be multiple, evenly spaced on the cover body 101, for expanding the cover body 101. Alternatively, there may be two arched rods 1031, respectively positioned at both ends of the cover body 101. When the middle section of the cover body 101 is corrugated, the arched rods 1031 only need to support the two ends of the cover body 101 to expand it. The arched bracket 103, when in use, expands the cover body 101 and places it above the patient's mouth and nose, providing a breathing space for the patient. The arched bracket 103 can enhance the support force of the cover body 101 and increase the stability of the face mask.

[0030] like Figure 1 and Figure 2As shown, in one embodiment, the cover 101 includes a telescopic section 1011, which is constructed as a corrugated structure. The telescopic section includes multiple foldable corrugated sheets connected end to end. Constructing the telescopic section 1011 as a corrugated tube reduces the number of components in the support structure and lowers manufacturing costs. Simultaneously, it allows for convenient and rapid folding or unfolding without compromising its supporting strength, improving surgical preparation efficiency.

[0031] like Figure 1 As shown, in one embodiment, the arched rod 1031 includes at least one hollow rod 1032, which is connected to a vent pipe 104, the vent pipe 104 being used to connect to an oxygen supply device.

[0032] The hollow rod 1032 is provided with a plurality of ventilation holes 1033. For example... Figure 1 As shown, the arched rod 1031 includes three hollow rods 1032 arranged along the bend of the telescopic section 1011. Each of these hollow rods 1032 has multiple ventilation holes 1033; the ventilation pipes 1033 are all connected to an oxygen supply device. Therefore, not only can sufficient breathing space be provided for the patient during surgery, but also air circulation within the cover 101 can be increased, improving patient comfort and facilitating a smooth surgical procedure.

[0033] like Figure 1 As shown, in one embodiment, the arched rods 1031 of the arched support 103 are disposed at the bends of each of the foldable corrugated sheets of the cover 101. Thus, the cover 101 provides strong support when unfolded, and does not affect its storage when closed.

[0034] like Figure 2 As shown, in one embodiment, the bottom support 200 is configured as a telescopic tube, which includes a tail tube 201 connected to the shoulder fixing member, a plurality of intermediate tubes connected end to end, and a head tube; the inner sidewall of the telescopic tube has a plurality of vent holes.

[0035] A vent pipe 104 is connected to the tail end pipe 201, and the vent pipe 104 is connected to an oxygen supply device. The bottom support 200 can also be a hollow pipe, and ventilation holes can be opened on it to increase air circulation and oxygen supply inside the cover 101. Therefore, the telescopic section 1011 of the cover 101 does not need to be equipped with an arched rod for support, making it easier to store.

[0036] like Figure 1As shown, in one embodiment, the cover 101 is made of silicone material; preferably, the cover 101 is made of transparent silicone material to facilitate observation of the patient's condition at any time. The arched rod 103 is made of polyvinyl chloride tubing.

[0037] like Figure 2 As shown, in one embodiment, the shoulder fastener 300 is constructed as a long strip of sheet, one end of which is rotatably connected to the tail tube 201. The shoulder fastener 300 is provided with an insert, one end of which is rotatably connected to the tail end of the bottom bracket 200 via a pin.

[0038] like Figure 1 As shown, in one embodiment, the nasal wing portion 102 is made of rigid plastic and is connected to the arched rod 103 at the head end of the mask 101. The nasal wing portion 102 not only supports the drape at the patient's nasal wing but also prevents the ophthalmic microscope from contacting the support, thus avoiding damage to the surgical area and the microscope.

[0039] In use, first open the shoulder fixation piece 300 and insert it into the patient's shoulder and neck area, pressing the patient's shoulder against the shoulder fixation piece 300. Then, open the face support cover 100 and fasten it to the patient's mouth and nose. Pull the bottom bracket 200 according to the patient's nose position so that the nasal wing part 102 is directly above the nose. During the operation, if the patient feels suffocated or as needed, the oxygen supply device can be turned on, delivering oxygen through the ventilation hole 1033. This also increases air circulation within the cover 101, improving patient comfort.

[0040] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
