Description

Technical Field

[0001] The utility model relates to the technical field of cranial head frame accessories, in particular to a damping transfer cushion block structure for a cranial head frame. Background Art

[0002] In the prior art, during craniotomy in neurosurgery, a cranial surgery head frame is often needed to fix the patient's skull. If the skull is not firmly fixed during the operation, it will affect the doctor's surgical operation and treatment effect. During the operation, the patient's comfort and good posture are also important conditions for anesthesia and surgery. Therefore, the quality of the head frame fixing device for cranial surgery affects the progress of the operation to a great extent. During the installation process of the cranial surgery head frame in the prior art, the doctor needs to carefully observe and fix the patient's head, which is prone to offset or error, resulting in the patient's head not being in a completely balanced state. The fundamental reason is that the connection relationship between the existing cranial head frame and the matching pad is a plug-in and sliding fit. The two are installed and adjusted in position through the plug-in and sliding of the wedge-shaped slide groove and the slider, and are fixed by bolts. After the head frame is fixed clinically, the state of the head frame and the installation pad is generally inclined, so the sliding of the pad and the head frame usually requires a certain gap to be left in order to be successfully inserted. However, the existence of this gap makes the sliding of the two too easy. Once the screws are loosened, it is easy to move a large distance, which is very dangerous for the patient. It also requires caution and care in operation, which has to occupy more of the doctor's energy and two-handed operation, making the clamping difficulty of other components increased.

[0003] The Chinese utility model patent with application number: 202222752782.7 discloses a directional head frame for cranial puncture, comprising: a positioning frame, which is a semi-circular bow-shaped structure; a fixed base, two of which are fixedly installed at both ends of the positioning frame; a skull fixing frame, which is installed on the fixed bases on both sides; a sliding seat, a sliding through hole is opened through the middle of the sliding seat, and the sliding seat is slidably connected to the positioning frame through the sliding through hole, a locking bolt is fixedly installed on the top of the sliding seat, a right side plate is installed on the right side of the sliding seat, the right side plate and the sliding seat form an accommodating space, and an anti-slip pressure plate is movably provided inside the accommodating space. However, the positioning of this type of directional head frame for cranial puncture is achieved by bolts, and the patient's head is fixed by a traditional pad structure to a bracket structure. If the bolts are loose, the positioning frame will be offset. Even if it has a spring structure, the patient's head will still be insufficiently supported and displaced over a large distance. That is, the spring structure has a poor blocking ability and cannot provide effective support for the head frame structure, which affects the surgical effect and increases the difficulty of operation, posing certain safety hazards to patients.
