Problems solved by technology

However, although the compression deformation of the polyurethane elastomer gel prepared by this invention is small, the compressive strength is low, and the antibacterial ability is very low, so it is not suitable for making materials that are in direct contact with human tissues.

Embodiment 1

[0038] refer to Figure 1~Figure 5 , the present invention is a kind of combined surgical position pad, comprising: a head fixing part, a cervical support and a shoulder pad, and the head fixing part 1, the cervical support 2 and the shoulder pad 3 are all polyurethane gel products, and the head The internal fixing part 1 is in the shape of a ring, and its hollow part 1-1 corresponds to the cranial occipital part; the bottom 2-1 of the cervical support 2 is a plane, and the top 2-2 is arc-shaped, and the center of the top is provided with a concave support surface 4; the shoulder pad 3 is columnar. The outsides of the head fixing part 1, the cervical support 2 and the shoulder pad 3 are all provided with sterile covers.

[0039] The setting of the sterile cover is convenient for postoperative disinfection, and it can be directly scrubbed and disinfected with alcohol, etc., and only need to replace the sterile cover when it is used again, which can effectively avoid the occurr...

Embodiment 2

[0045] refer to Figure 1~Figure 6 , the operation combination type body position pad described in the present embodiment 2 is different from the embodiment 1 in that:

[0046] The bottom of the cervical spine support 2 is evenly provided with circular bumps or linear strips to increase the friction between the cervical spine support 2 and the placement surface.

[0047] refer to Figure 6 , the bottom of the head holder 1 is connected to a flat plate 5, and the flat plate 5 is provided with a through hole 6 corresponding to the hollow part of the head holder 1, so that the force can be effectively dispersed and the stability of the head holder 1 can be increased. , The setting of the through hole 6 is convenient for the ventilation of the cranial occipital part.

[0048] The method of using the combined anterior cervical position pad in the present invention is as follows: after wrapping the outer layer of the position pad with a sterile sleeve, place the shoulder pad on th...

Embodiment 3

[0050] The preparation method of polyurethane gel of the present invention comprises the following steps:

[0051] 1) Dissolve 40 parts by weight of polyether polyol in 4 parts by weight of foaming agent, then add 0.12 parts by weight of carboxymethyl chitosan, 80 parts by weight of isocyanate and 0.6 parts by weight of catalyst, and stir for 18 minutes at 25°C;

[0052] Described whipping agent is acetone, and described catalyzer is dibutyltin dilaurate;

[0053] 2) Add 18 parts by weight of triethylamine, 35~40°C, under nitrogen protection, stir for 45 minutes; add 20 parts by weight of bacterial cellulose solution, the content of bacterial cellulose in the bacterial cellulose solution is 2.5wt%, 50~ Stir at 60°C for 105 minutes, let stand, and freeze-dry to obtain the product.

[0054] In this embodiment, the polyether polyol is a hydrophilic polyether polyol.

[0055] In this embodiment, the purification method of the bacterial cellulose is as follows: mechanically pulve...

Abstract

The invention provides a combined type body posture pad for operation, and belongs to a body posture fixing device. The combined type body posture pad for operation comprises a head fixing member, a cervical vertebra holder and a shoulder pad, wherein the head fixing member, the cervical vertebra holder and the shoulder pad are made of polyurethane gel, the head fixing member if of a circular shape, the hollow part of the head fixing member corresponds to a cranium occipitalia, the bottom of the cervical vertebra holder is planer, the top of the cervical vertebra holder is of a cambered surface, a concave holding surface is arranged on the top center of the cervical vertebra holder, and the shoulder pad is cylindrical. An aseptic cover is arranged on the external of each of the head fixing member, the cervical vertebra holder and the shoulder pad. The combined type body posture pad, when used in a body posture placing process for an anterior cervical operation, has the advantages of being convenient for use, being firm for fixing a neck portion and being light in skin compression. The comfort level and operation convenience for a surgeon are improved.

Description

technical field [0001] The invention belongs to the technical field of body position fixing devices, and in particular relates to a surgical combined body position cushion. Background technique [0002] The placement of the surgical position is one of the keys to the success of a surgery. The surgical position should not only ensure that the position is well fixed, fully expose the surgical field, but also avoid complications caused by pressure on the skin and tissues. Anterior cervical surgery is an effective surgical method for the treatment of cervical spondylotic myelopathy. The cervical vertebral body is adjacent to the esophagus and trachea, the peripheral blood vessels and nerves are abundant, and the tissue structure is complex. higher requirements. For the positioning of anterior cervical surgery, sponge cushions, sandbags, and head rings are traditionally used for fixation. The sponge cushions are relatively soft and have poor fixation performance. Sandbags placed...
