[0001] The utility model relates to the technical field of medical surgery, in particular to a head fixing device for lateral position surgery. Background Art

[0002] With the precision of medical treatment, the use of lateral position in medical treatment and surgery has become very common. For example, in kidney, adrenal gland, ureter, chest, lung and other surgeries, lateral position is a routine position. When in lateral position, the patient's head and cervical spine need to be kept at the same level, while conforming to the physiological curvature of the cervical spine, so that the patient's lateral position is stable, safe and comfortable, to ensure the smooth progress of the operation, and at the same time reduce the discomfort caused by the patient's postoperative position. However, the existing operating bed is flat, and it is impossible to directly raise the patient's head. In order to keep the patient's head and cervical spine at the same level during lateral surgery, the current practice is for medical staff to use a combination of folded cloth, sponge pads, gel pads and other position pillows to raise the patient's head before surgery.

[0003] Obviously, the above adjustment method requires a lot of cloth and other body position pillows to be assembled manually, which brings inconvenience to the work of medical staff. The body position pillows are randomly made and matched, which is not only troublesome, but also unstable and prone to unplanned movement, resulting in cervical spine injury, which poses a serious safety hazard. In addition, the head and neck fixation is not standardized, which leads to head and neck discomfort in patients in the side-lying position after surgery. Summary of the invention

[0004] The utility model provides a head fixing device for lateral-lying surgery in view of the problems of the prior art, which can effectively improve the work efficiency of lateral-lying surgery, reduce the workload of medical staff, and provide protection for the patient's body position safety.

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation manner are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0020] like Figure 1 and Figure 2As shown, the utility model provides a head fixation device for lateral position surgery, including a coat 1 and an airbag 2. The top of the coat 1 is provided with a support portion 3 for supporting the patient's head, and the support portion 3 is made of a skin-friendly hard material; the side wall of the coat 1 is provided with an inflation hole, and the airbag 2 has an inflation tube 4. When the airbag 2 is installed on the coat 1, the inflation tube 4 protrudes to the outside through the inflation hole; the inflation tube 4 is connected to a three-way piece 9, and the three-way piece 9 is used to control the obstruction state of the inflation tube 4.

[0021] In actual production, the length of the jacket 1 is 50-55cm, the width is 20-30cm, and the total height of the jacket 1 is not higher than 18cm when the airbag 2 is filled with air and props up the jacket 1; in addition, the skin-friendly hard material described in the utility model only needs to ensure that the patient's head will not sink too much into the support part 3, for example, it can be thicker polyester cotton, polyester, spandex, etc. When the utility model is needed, the medical staff first puts the utility model on the operating table and pads it under the patient's head, and then inputs gas to the airbag 2 through the three-way piece 9, so that the airbag 2 gradually expands and is too high for the patient's head; when the patient's head is lifted to the patient's cervical spine in a horizontal state, no more gas is input to the airbag 2, so that the airbag 2 maintains this state until the operation is completed; and when the support part 3 holds the patient's head, since the support part 3 has a certain hardness, it will not be deformed, and it can be ensured that the expansion and contraction of the airbag 2 drives the patient's head to rise and fall slowly, thereby protecting the patient's safety.

[0022] The jacket 1 of the utility model is preferably made of cloth, and the support part 3 can be made of a material with a certain hardness and a buffering function such as rubber to ensure that the patient's head will not be subjected to a rigid collision. Through the use of the utility model, medical staff can adjust the patient's head posture by only using the utility model instead of constantly adding / reducing cloth and rubber balloons, which can be used to adjust the patient's head posture in any posture, thereby reducing the burden on medical staff.

[0023] In this embodiment, an inflation device 5 is also included. The first end of the three-way piece 9 is connected to the inflation tube 4, the second end is connected to the inflation device 5, and the third end is connected to the atmosphere. The inflation device 5 is provided with a sensing device for sensing the internal air pressure of the airbag 2.

[0024] That is, the three ends of the three-way piece 9 are respectively connected to the atmosphere, the airbag 2 and the inflator 5. The three-way piece 9 is preferably a push-type three-way piece 9 or a knob-type three-way piece 9, which is a conventional structure, for example, the scheme disclosed in the utility model with patent numbers 202021876172.2 and 201320459097.3, or the valve core and valve body structure disclosed in the utility model with patent number 202020124142.X can be adopted.

[0025] The working mode of the three-way piece 9 is as follows: when inflation is required, the airbag 2 is controlled to be connected with the inflation device 5 and the airbag 2 is cut off from the outside atmosphere, so that the inflation device 5 can slowly inflate the airbag 2; when the inflation is completed, the airbag 2 is controlled to be cut off, for example, the inflation device 5 of the three-way piece 9 is connected with the external atmosphere and the inflation device 5 is closed; and when the airbag 2 needs to be deflated, the airbag 2 is controlled to be connected with the outside atmosphere, and the high-pressure gas in the airbag 2 will be actively discharged to the outside.

[0026] The inflation device 5 adopted by the present invention can be a conventional air pump, and the sensing device provided therein is arranged at the output end, and can be inserted into the airbag 2 to monitor the air pressure change of the airbag 2 during inflation: when the air pressure of the airbag 2 reaches a certain value, it can be ensured that the airbag 2 has sufficient supporting force to ensure the head posture; and when the inflation is completed, the inflation device 5 can be closed and wait for a certain period of time. When the air pressure inside the airbag 2 does not change, it proves that the airbag 2 is not damaged, and it can continue to be used at this time, thereby ensuring that the airbag 2 supports the patient's head stably during surgery.

[0027] In this embodiment, a zipper 6 is provided on one side of the jacket 1, and the airbag 2 is detachably installed in the jacket 1; the inflation hole is provided on the back side / the other side of the jacket 1. That is, the inflation tube 4 is not on the same side as the zipper 6 nor on the front side, because the front side is blocked by the patient's upper body and is difficult to operate.

[0028] As another embodiment of the utility model, the number of the inflation holes is 1-3, the number of the airbags 2 is 1-3, the inflation holes are assembled with the inflation tubes 4 in one-to-one correspondence; the inflation tubes 4 and the three-way piece 9 are detachably arranged.

[0029] That is, by having multiple airbags 2, the height adjustment accuracy can be made more precise. When the airbag 2 at the bottom has not yet reached the required height, the upper airbag 2 can continue to be inflated, so that the height adjustment of the utility model is stable and precise. When an airbag 2 is found to be damaged during surgery, other airbags 2 can be inflated and used to avoid delaying the progress of the surgery.

[0030] In addition, the inflation tube 4 and the three-way piece 9 are detachable so that when the airbag 2 is damaged and needs to be replaced, the inflation tube 4 can be separated from the three-way piece 9 and the inflation tube 4 can be retracted from the inflation hole and the airbag 2 and the inflation tube 4 can be taken out from the zipper 6 end of the jacket 1 for easy replacement.

[0031] In this embodiment, the middle of the top of the support portion 3 is recessed inward to accommodate the patient's head and prevent the patient's head from moving. The maximum height difference of the top of the support portion 3 is 3-6 cm, so that the patient's head can be reliably maintained on the support portion 3 to avoid sliding and affecting the safety of the operation.

[0032] Specifically, the position where the support part 3 is recessed inwardly is the limiting part 8 in the figure, and its shape is preferably arc-shaped. Alternatively, a neck pillow (not shown in the figure) can be provided and installed on the support part 3 for the patient to use.

[0033] In this embodiment, a pneumatic control valve 7 is provided at the third end of the three-way piece 9, and the pneumatic control valve 7 is used to control the flow rate when the airbag 2 is exhausted. When exhausting, it is necessary to exhaust slowly to ensure that the height of the jacket 1 is slowly lowered, so as to protect the patient's head and cervical spine from being injured in a large drop.

[0034] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
