A head frame for craniocerebral surgery

Abstract

This utility model discloses a head frame for craniocerebral surgery, including a fixation component and an adjustment component connected to one side of the fixation component. By setting the adjustment component, the position can be locked while allowing surgeons to make fine adjustments to the head frame from multiple angles and directions according to actual needs. The design of the curved arm and rotating seat further increases the adjustability of the head frame, enabling it to meet various positioning requirements in complex surgical environments. In particular, the ingenious combination of the force applicator, the jack, and the movable seat provides gentle yet stable support for the patient's head, reducing discomfort that may be caused to the patient during long-term surgery. More importantly, the adjustment component ensures smoothness during the adjustment process, and the fixation component ensures that the head frame can maintain a stable fixation even after long-term use, avoiding potential shaking problems caused by aging or wear.

Description

Technical Field

[0001] This utility model relates to the field of surgical head frame technology, specifically to a head frame for fixing craniocerebral surgery. Background Technology

[0002] Head frames used in craniocerebral surgery, often referred to as head braces or skull clamps, are essential tools for stabilizing a patient's head during neurosurgical procedures. The primary purpose of these devices is to ensure the patient's head remains immobile during surgery, thereby improving surgical precision, reducing surgical risks, and protecting patient safety.

[0003] In current craniocerebral surgery, the head fixation frame used is crucial for ensuring head stability during the procedure. However, existing head fixation frames have some limitations, such as the need for further improvement in stability. Especially after long-term use, the limiting structure ages or wears down over time, causing unnecessary displacement of the fixation and adjustment components when there is slight shaking during surgery. This displacement not only affects the precision of the surgery but may also pose potential risks to the patient. In addition, the fixation arms of existing craniocerebral surgery head fixation frames are usually fixed, lacking sufficient flexibility to adapt to different head shapes and sizes of patients, making it difficult for surgeons to achieve the best fixation effect according to each patient's specific situation. Utility Model Content

A sixth limit bolt is provided on one side of the fixed arm, and a movable seat is provided on one side of the sixth limit bolt. Multiple double-ended bolts are provided on one side of the movable seat, and a movable plate is fixedly installed on the double-ended bolts.

[0038] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to fix the head frame on the operating table, the second fixing seat 109 is placed on both sides of the operating table, and then the second mounting bolt 110 and the second limiting plate 111 are tightened together to fix it on both sides of the operating table. Then, the first mounting bolt 108 and the mounting slide rail 107 are connected to the second fixing seat 109. Then, the first fixing bolt 112, the limiting hole 103 and the adjusting column 102 cooperate to adjust according to the width of the operating table. Then, the second fixing bolt 105, the first limiting plate 106 and the first fixing seat 104 cooperate to fix the first fixing seat 104 on the mounting slide rail 107. This can facilitate installation and fixation according to different operating tables, thereby better adapting to different specifications of operating tables and ensuring the installation and fixation effect of the head frame.

[0039] When the headframe needs adjustment and positioning, the adjusting seat 201 can slide along the outer wall of the adjusting cylinder 101 and be fixed in position by the first limiting bolt 202. This allows the entire adjusting assembly 2 to be adjusted in position along the length of the adjusting cylinder 101 as needed. By rotating the adjusting arm 204 on the second limiting bolt 203, the angle position of the crank arm 206 can be changed. The third limiting bolt 205 is used to fix the position of the adjusting arm 204. The fourth limiting bolt 207 connects to the rotating seat 208, facilitating its rotation or angle adjustment within a certain range relative to the crank arm 206. Rod 210 can slide inside rotating seat 208 and its position is limited by contact with positioning bolt 209. The relative position of fixed arm 211 and sliding arm 213 is adjusted by fifth limiting bolt 212. Sliding arm 213 can slide in adjustment groove 4 to adapt to different working requirements. Force application mechanism: Force applicator 214 applies pressure or force to target through ejector pin 215. At the same time, sixth limiting bolt 216 controls the position of movable seat 217. Ejector pin 220 on movable plate 219 can be finely adjusted by positioning bolt 221 to ensure the accuracy of force application.

[0040] When the angle needs to be adjusted and then the limit is set again, when the adjustment handle 226 is rotated, the bidirectional screw 222 drives the moving seat 223 to move along the screw axis, thereby driving the movable plate 224 and the positioning plate 225 to move within the positioning port 6, so as to achieve precise adjustment of each component. The ratchet self-locking structure 227 ensures that the adjusted state will not be loosened due to external vibration or other factors, ensuring the stability and reliability of the adjustment result, and thus avoiding the shaking problem caused by the aging or wear of the limit structure over time.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
