[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] like Figures 1 to 6 As shown, the utility model provides a facial protection pad for patients undergoing da Vinci surgery, including an upper transparent mask 1 and a lower plastic mask 2, the sides of which are away from a guide mechanism 5 and two movable ends of a hinge 8 are fixed by screws. When closed, the upper transparent mask 1 and the lower plastic mask 2 can fit completely together. The upper transparent mask 1 is made of PVC and PMMA, preferably PMMA, which is transparent, sterile and has high strength. The lower plastic mask 2 is made of PP or PE, which has high strength.
[0029] Both ends of the upper transparent mask 1 and the lower plastic mask 2 are set to be flat. The flat surface of the lower plastic mask 2 is convenient for fitting with the bed, and the upper end surface of the upper transparent mask 1 is a flat surface to reduce the volume, so that the da Vinci robot has more surgical space.
[0030] The two sides of one end of the lower plastic mask 2 can abut against the upper transparent mask 1 to form a cavity for accommodating the head 4. The upper transparent mask 1 is longer than the lower plastic mask 2 and extends to the patient's neck. A through placement groove 7 for placing the back of the head is provided in the middle of the lower end of the lower plastic mask 2. The placement groove 7 is rectangular and has an arc that fits the head 4.
[0031] The guide mechanism 5 includes a guide plate 53 disposed below the inner surface of the upper transparent mask 1 and used to constrain the conduit. A plurality of guide grooves 54 for guiding the conduit are provided at the lower end of the guide plate 53. Figure 6 As shown, it also includes a fixing sleeve 51 welded to the lower part of the inner surface of the upper transparent mask 1, a slider 52 is provided in the inner cavity of the fixing sleeve 51 for longitudinal sliding, and buffer springs 56 are provided between the upper ends of the sliders 52 and the top of the inner cavity of the fixing sleeve 51. The elastic force of the spring 56 should not be too large, and it can be pushed with normal force. Guide seats 6 are fixedly provided at positions corresponding to the guide plates 53 on both sides of the inner surface of the upper transparent mask 1, and grooves for accommodating pipes are provided at opposite ends of the two guide seats 6.
[0032] It should be noted that, except for the flexible pad 9, the hinge 8 and the spring 56 structure, all other parts of the device are made of hard plastic material.
[0033] In order to increase the stability of the connection between the lower plastic mask 2 and the upper transparent mask 1, a fixing component may also be added, such as a quick-release screw fixing, a snap button and the like, which are not shown in the figure and are not provided in this embodiment of the device because closure can be achieved under the action of its own gravity.
[0034] Ear-receiving grooves 3 for placing the patient's ears are provided on both sides of the surface of the lower plastic mask 2. The shape and size of the ear-receiving grooves 3 can be set larger to accommodate patients with different head shapes.
[0035] Specifically, the inner surface of the lower plastic mask 2 and the inner surfaces of the corresponding positions of the upper transparent mask 1 and the lower plastic mask 2 are glued with a flexible pad 9, and the flexible pad 9 is made of memory foam, latex, cloth, and fluff, preferably latex, which is more flexible and comfortable.
[0036] Principle and process of this utility model:
[0037] The doctor first inserts the endotracheal tube into the patient's oral cavity. After completion, the patient is then made to lie flat on the operating table. The doctor lifts the patient's head 4 and inserts one end of the lower plastic mask 2 under the patient's head 4, so that the top of the patient's head is pressed tightly against one end surface of the lower plastic mask 2. The upper transparent mask 1 is then covered to close it with the lower plastic mask 2, so that the patient's head 4 is wrapped in the cavity formed by the upper transparent mask 1 and the lower plastic mask 2, thereby achieving a protective effect. The patient's ears can leak out through the ear slots 3. In order to make the guide mechanism 5 located on the patient's neck, the user needs to adjust the position of the patient's head 4 and the device;
[0038] The doctor needs to install the tracheal tube according to the direction of the guide groove 54 at the lower end of the guide plate 53, so that the tracheal tube can be bent. It should be noted that the bending angle of the guide groove 54 cannot cause the tracheal tube to have poor air supply due to bending. Therefore, the bending part needs to be set to a large angle to make the tracheal tube change direction, and then the tracheal tube is clamped into the guide seat 6 to be fixed, so that the tracheal tube is extended to the patient's side, at a lower position, so as to protect the tracheal tube.
[0039] Because the slider 52 is always located at the lowest point of the fixing sleeve 51 under the action of the spring 56, the tracheal tube can be pressed downward to prevent the tracheal tube from tilting and interfering with the robot. When the resistance is too large, the slider 52 will also slide in the side slide groove 55.
[0040] The device can protect the face and the endotracheal tube to prevent adverse events, and at the same time, it will not squeeze the patient's face and is easy to adjust and move.
[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
