Head rest for operating table

Abstract

The invention provides a head rest for an operating table. The head rest for the operating table comprises a base and a head fixture, wherein the base is connected with an operating table; and the head fixture is connected with the base. The head fixture comprises a first supporting part, a second supporting part, a first clamping part and a second clamping part, wherein the first supporting part is used for supporting the frontal bone of a patient's head; the second supporting part rotatably connected with the first supporting part is used for supporting the cheekbone of the patient's head; the first clamping part which is connected with the first supporting part and capable of rotating in the vertical direction is used for clamping the occipital bone of the patient's head; and the second clamping part arranged on the second supporting part is used for clamping the mandibular angle of the patient's head. The base is provided with a hollow projection area corresponding to the portion just below the patient's neck. Traction of the patient's neck or accurate displacement of the patient's head in horizontal and vertical directions can be realized by moving the head rest during surgery.

Description

technical field [0001] The invention relates to a medical device, in particular to a head frame for an operating table. Background technique [0002] In surgery, especially in cervical spine surgery, patients often need to lie prone on the operating table. At this time, it is necessary to set up a head frame to carry the patient's head, so as to fix the patient's head during the operation and ensure the patient's stability during the operation. breathing easily. [0003] Figure 1a It is the front view of the human skull, and Fig. 1b is Figure 1a For a lateral view of the skull shown, see Figure 1a As shown in , 1b, currently commonly used surgical head frames, the parts that are in contact with the patient's head for support often adopt a U-shaped structure (such as the panel structure provided by Chinese patent CN201370724Y), which is in contact with the frontal bone 10 and cheekbones 11 of the human skull , so as to provide support for the patient's head and ensure tha...

AI Technical Summary

Problems solved by technology

This commonly used head frame with U-shaped structural support parts cannot fix the patient's head with the head frame, which means that the patient's head cannot be moved by moving the head frame. Therefore, during the operation, the head frame cannot be moved. Provides the function of traction on the patient's neck

[0004] At present, in cervical spine surgery, there is also an American Mayfield head fixation system that is often used. The part of the Mayfield head fixation system that fixes the patient's head is a three-nail system, and the positioning nails of the three-nail system need to be nailed into The parietal bone 13 or the temporal bone 14 of the human skull, so as to realize the firm fixation to the patient's head, but in this way, it is necessary to pull the patient's neck through the Mayfield head fixation system during the operation. damage to the patient's skull

[0005] The existing head frames are often manually adjusted in place by the hand strength of the operator before the operation, and the patient's head is supported after locking, but the precise fine-tuning of the position of the head frame cannot be realized, especially during the operation. Precise fine-tuning of the rack position to adjust the patient's head position

Chinese patents CN201370724Y and CN201295354Y provide two kinds of surgical headframes. Although these two kinds of surgical headframes solve the problem of fine-tuning the position of the headframe horizontally or vertically, they do not provide a connection between the headframe and the patient's head. Therefore, during the operation, these two kinds of headgears can not ensure the displacement of the patient's head due to the horizontal or vertical fine-tuning of the headgear positions. It is also inconvenient to provide the function of pulling the patient's neck during the operation. In addition, when the patient lies prone on the operating table and the head is placed on the head frame, the operation head frame is still the same as the existing head frame for these two days. There are structural parts of the head frame in the lower area facing the patient's neck, which is very unfavorable for X-ray shooting of the patient's neck during the operation
