[0048] As Figure 5 shown, the elastic protective sleeve 40 comprises an inner layer 41 and an outer layer 42, the inner layer 41 is made of waterproof material (in this embodiment, nitrile or latex is specifically selected), and the outer layer 42 is made of water-absorbing material (in this embodiment, a textile with good water-absorbing and elastic properties is specifically selected).

[0049] Figure 6 is Figure 1 an enlarged view of the A area in FIG. 4.

[0050] As Figure 6 shown, the liquid collecting part 50 comprises a water supporting tray 51 and a mounting plate 52.

[0051] Figure 7 is Figure 2 an enlarged view of the B area in FIG. 4; Figure 8 is Figure 3 a corresponding perspective view from another angle.

[0052] As Figure 1 , 2 , 3, 6, 7 and 8, the upper surface of the water supporting tray 51 is an inclined mirror surface, and the width of the water supporting tray 51 is not less than the length of the extension direction of the protective pad 30, and the length of the water supporting tray 51 is not less than the maximum value of the adjustable interval between two protective pads 30.

[0053] The water supporting tray 51 is provided with a through hole 51a reaching the bottom surface at the deepest part of the inclined surface of the inclined upper surface.

[0054] The mounting plate 52 is integrally extended on one side of the water supporting tray 51 having the through hole 51a, and the mounting plate 52 is perpendicular to the plane on which the water supporting tray 51 is located.

[0055] The support plate 10 is provided with a plurality of insertion holes 10a; the mounting plate 52 is provided with a plurality of matching holes 52a corresponding to the plurality of insertion holes 10a. The two mounting plates 52 are arranged on both sides of the support plate 10 and are clamped on the support plate 10 by rotating a plurality of bolts 4 and nuts 5 inserted through the insertion holes 10a and the matching holes 52a, so that the liquid collecting part 50 is detachably arranged on the support plate 10.

[0056] As Figures 1 to 8 shown:

[0057] The conduit 60 is a silica gel hose, one end of which is connected and communicated with the through hole 51a.

[0058] The liquid storage part 70 is connected and communicated with the end of the conduit 60 away from the through hole 51a, specifically, the liquid storage part 70 in this embodiment is a negative pressure suction bottle.

[0059] In a variant of the embodiment, the head support 100 for brain surgery does not have the conduit 60 and the liquid storage part 70, and the liquid collecting part 50 of the head support 100 for brain surgery is a bag-shaped structure of a plastic material with a parabolic shape, and the opening of the bag-shaped liquid collecting part 50 is attached and adsorbed to the peripheral side of the two elastic protective sleeves 40, so as to ensure that the blood and / or disinfectant liquid of the patient's head during the brain surgery falls into the bag-shaped liquid collecting part 50, and does not fall to the ground.

[0060] Use of the head support 100 for brain surgery:

[0061] S10, before the brain surgery, adjust the angles between the first rotating arm 1, the second rotating arm 2, the third rotating arm 3 and the support plate 10, and then adjust the distance between the two brackets 20, so that the distance between the two corresponding protective pads 30 matched to the two brackets 20 matches the patient's head.

[0062] S20, after the elastic constriction opening 40a of the elastic protective sleeve 40 is opened, the elastic protective sleeve 40 is sleeved on the protective pad 30, and then the hand is released, and the elastic constriction opening 40a is tightly contracted on the support plate 10.

[0063] S30, place the patient's head on the two protective pads 30.

[0064] S40, perform brain surgery, and during the surgery, the disinfectant liquid used by the surgeon and / or medical staff on the patient's head and the blood flowing from the head during the surgery are absorbed by the water-absorbing material outer layer 42 of the elastic protective sleeve 40 sleeved outside the protective pad 30.

[0065] During the surgery, the waterproof material inner layer 41 of the elastic protective sleeve 40 and the elastic constriction opening 40a effectively prevent the disinfectant liquid and / or blood from penetrating into the silica gel material protective pad 30.

[0066] If the patient is in a prone position on the operating table and the head is supported by the protective pad 30 during the brain surgery, the surgeon and / or medical staff can observe whether the patient's head and face are pressed by reflecting the mirror surface upper surface of the water tray 51 during the surgery.

[0067] During the surgery, if the amount of blood and / or disinfectant liquid is slightly more and cannot be immediately absorbed by the water-absorbing material outer layer 42 of the elastic protective sleeve 40, it will flow into the water tray 51 and gather in the inner bottom along the inclined surface, and be absorbed and stored by the liquid storage part 70 through the through hole 51a and the conduit 60.

[0068] S50, after the surgery is completed, remove the elastic protective sleeve 40, dispose of the disinfectant liquid and blood in the liquid storage part 70, and perform the corresponding surgery finishing work.

[0069] Effects of the embodiment

[0070] The head support for craniocerebral surgery provided by the embodiment comprises a support plate, a bracket and a protective pad, two brackets are adjustably arranged on the support plate, and two protective pads made of silica gel are correspondingly sleeved on the brackets and cooperated with each other to support the head of a patient during craniocerebral surgery. The protective pad is sleeved with an elastic protective sleeve of secondary polishing type, the shape of the elastic protective sleeve matches that of the protective pad, the elastic protective sleeve has an inner layer and an outer layer, the inner layer of the elastic protective sleeve is made of waterproof material, and the outer layer of the elastic protective sleeve is made of water-absorbing material.

[0071] Therefore, the head support for craniocerebral surgery has the following beneficial effects compared with the prior art:

[0072] (1) The elastic protective sleeve can be sleeved on the protective pad made of silica gel to protect the protective pad, thereby preventing the protective pad from being polluted by blood and / or disinfectant liquid during surgery and accelerating the aging of the protective pad.

[0073] (2) The elastic protective sleeve of secondary polishing type is disposable, which can isolate the contact between the head of the patient and the protective pad to reduce the risk of infection and effectively protect the protective pad.

[0074] (3) The inner layer of the elastic protective sleeve is made of waterproof material to prevent the protective pad from being penetrated by blood and / or disinfectant liquid, and the outer layer is made of water-absorbing material to effectively absorb blood and / or disinfectant liquid during surgery, thereby reducing the risk of blood and / or disinfectant liquid dropping to the ground and eliminating the need to lay plastic cloth on the ground under the head support in the prior art.

[0075] Further, one end side of the elastic protective sleeve has a convex elastic constriction. In this way, when the elastic protective sleeve is sleeved on the protective pad, blood and / or disinfectant liquid on the head of the patient during craniocerebral surgery cannot penetrate into the protective pad.

[0076] Further, the head support for craniocerebral surgery further comprises a liquid collecting part, the liquid collecting part is in a disc-shaped structure, and is arranged on the support plate and below the protective pad. In this way, even if the blood and / or disinfectant liquid on the head of the patient during craniocerebral surgery cannot be absorbed by the outer layer of the water-absorbing material of the elastic protective sleeve, the blood and / or disinfectant liquid will drop on the liquid collecting part and will not drop on the ground.

[0077] Further, a plurality of insertion holes are arranged on the support plate, the side surface of the disc-shaped liquid collecting part extends two installation plates perpendicular to the plane of the disc-shaped liquid collecting part, the installation plates have matching holes corresponding to the plurality of insertion holes, the two installation plates are arranged on the two sides of the support plate, and are clamped on the support plate by rotating and connecting a plurality of bolts and nuts inserted through the insertion holes and the matching holes. In this way, the liquid collecting part is detachably arranged on the support plate, and the whole head support for craniocerebral surgery is modularized.

[0078] Further, the upper surface of the liquid collecting part of the disc-shaped structure is a mirror surface. In this way, when the patient lies on the operating table in a prone position and the head is supported by the headrest, the surgeon and / or medical staff can observe whether the head and face of the patient are pressed through the reflection of the mirror surface of the upper surface of the liquid collecting part.

[0079] Further, the upper surface of the liquid collecting part of the disc-shaped structure is inclined towards the direction of the support plate. In this way, the blood and / or disinfectant liquid that drips into the liquid collecting part can be gathered on the inner side of the liquid collecting part, and the force receiving position (the area where the blood and / or disinfectant liquid accumulates) of the liquid collecting part is close to the support plate, so that the liquid collecting part is more stable when arranged on the support plate.

[0080] Further, the width of the liquid collecting part is not less than the length of the extension direction of the headrest, and the length of the liquid collecting part is not less than the maximum value of the adjustable distance between two headrests. In this way, when the distance between the two headrests is adjusted to adapt to the size of the head of different patients, the liquid collecting part can well collect the blood and / or disinfectant liquid that drips down.

[0081] Further, the liquid collecting part has a through hole, and the headrest for craniocerebral surgery further comprises a catheter connected and communicated with the through hole, used for draining the blood and / or disinfectant liquid in the liquid collecting part; and a liquid storage part connected and communicated with the end of the catheter away from the liquid collecting part, used for storing the blood and / or disinfectant liquid drained by the catheter. In this way, the following beneficial effects are achieved: (1) The blood and / or disinfectant liquid in the liquid collecting part can be quickly drained and prevented from accumulating, and if the patient lies on the operating table in a prone position and the head is supported by the headrest during the craniocerebral surgery, it is more convenient for the surgeon and / or medical staff to observe whether the head and face of the patient are pressed through the reflection of the mirror surface of the upper surface of the liquid collecting part. (2) Generally, the amount of blood and / or disinfectant liquid during the craniocerebral surgery is not large, but if the liquid amount increases suddenly, the blood and / or disinfectant liquid in the liquid collecting part can still be quickly drained to prevent accumulation.

[0082] Further, the liquid storage part is a negative pressure suction bottle. In this way, the blood and / or disinfectant liquid in the liquid collecting part can be drained more quickly.

[0083] Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
