Description

Technical Field

[0001] This utility model relates to the technical field of equipment related to craniocerebral surgery, and in particular to a head support for craniocerebral surgery. Background Technology

[0002] Neurosurgery, a branch of surgery, is a highly specialized and sophisticated discipline that, while relying primarily on surgery for treatment, applies unique neurosurgical research methods to study the human nervous system—including the brain, spinal cord, and peripheral nervous system—and related appendages such as the skull, scalp, cerebral blood vessels, and meninges. It investigates injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or functional disturbances, such as epilepsy, Parkinson's disease, and neuralgia. Neurosurgery also explores new diagnostic, treatment, and preventative technologies. During craniotomy in neurosurgery, a craniosurgery head frame is often used to stabilize the patient's skull. Insecure head fixation during surgery can negatively impact surgical procedures and treatment outcomes. Patient comfort and proper positioning are also crucial for anesthesia and surgical execution; therefore, the quality of the craniosurgery head frame significantly influences the success of the surgery.

[0003] During the installation of a head brace for craniocerebral surgery, doctors need to carefully observe and fix the patient's head. However, existing head braces for craniocerebral surgery are basically directly fixed without the possibility of fine-tuning. This forces the patient to be rigidly fixed in a fixed position, which greatly affects the patient's comfort and may cause the patient to be in an incorrect posture, thus affecting the progress of the surgery. Utility Model Content

[0004] To overcome at least one of the defects described in the prior art, this utility model provides a head support for craniocerebral surgery. This solves the problems of rigid fixation of the head support, which affects patient comfort and the progress of the surgery.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A head support for craniocerebral surgery includes a fixed L-shaped support and a movable L-shaped support. One end of the movable L-shaped support is movably connected to the fixed L-shaped support. A first fixing block is provided at the end opposite to the connection between the fixed L-shaped support and the movable L-shaped support. A first U-shaped fixing member is slidably connected to the first fixing block. A first adjusting mechanism is threadedly connected to the first fixing block. The output end of the first adjusting mechanism is connected to the first U-shaped fixing member. A second fixing block is provided at the end opposite to the connection between the movable L-shaped support and the fixed L-shaped support. A second U-shaped fixing member is slidably connected to the second fixing block. A second adjusting mechanism is rotatably connected to the second fixing block. The output end of the second adjusting mechanism is connected to the second U-shaped fixing member. A bracket is provided at the connection between the fixed L-shaped support and the movable L-shaped support. A support plate is movably connected to the bracket via a supporting mechanism.

[0007] The above solution uses a fixed L-shaped support frame with a first U-shaped fixing member and a movable L-shaped support frame with a second U-shaped fixing member to fix both sides of the patient's head. The first and second adjustment mechanisms can be used to fine-tune the first and second U-shaped fixing members respectively, so that while fixing the patient's head, the first and second U-shaped fixing members can improve the patient's comfort. The surgeon can also make fine adjustments during the operation to better perform the operation. The support mechanism can adjust the support plate so that the patient's face is positioned on the support plate in a more comfortable state.

[0008] Furthermore, the first fixing block is provided with a first sliding groove, and the first U-shaped fixing member is provided with a first sliding frame on one side. The first sliding frame is slidably connected in the first sliding groove, and the first sliding frame is provided with a first long slot.

[0009] The above-mentioned further solution enables the first U-shaped fastener to slide up and down and move left and right on the first fixed block without affecting the tilt of the first U-shaped fastener. The stability of the first U-shaped fastener is ensured during the fine adjustment process through the cooperation of the first sliding groove and the first sliding frame.

[0010] Furthermore, the first adjusting mechanism includes a first adjusting screw and a first fastening screw. The first fixing block is provided with a first screw hole, which penetrates the first fixing block. One end of the first screw hole is located in the first sliding groove. The first adjusting screw is threadedly connected to the first screw hole. One end of the first adjusting screw passes through the first long slot and is located in the first sliding frame with a first limiting plate. The other end is provided with a first handle. The middle of the first adjusting screw is provided with a second screw hole. The first fastening screw is threadedly connected to the second screw hole. One end of the first fastening screw passes through the first limiting plate and is located in the first sliding frame with a second limiting plate. The other end passes through the first handle to the outside with a second handle.

[0011] With the above-mentioned further solution, when the first limiting plate moves to the bottom of the first slide groove by rotating the first handle, the first limiting plate can clamp the first slide frame through the bottom of the first slide groove. When it is necessary to extend or adjust the first U-shaped fixing member, the first limiting plate moves to the opening of the first slide groove by rotating the first handle. When it moves to the distance that needs to be extended, the height of the first U-shaped fixing member is adjusted. The second handle is rotated so that the first limiting plate abuts against the inner side of the first slide frame and the second limiting plate abuts against the first U-shaped fixing member, thereby locking the first slide frame and preventing the first slide frame from moving downward.

[0012] Furthermore, the second fixing block is provided with a second sliding groove, and the second U-shaped fixing member is provided with a second sliding frame on one side. The second sliding frame is slidably connected in the second sliding groove, and the second sliding frame is provided with a second long slot.

[0013] The above-mentioned further solution enables the second U-shaped fastener to slide up and down and move left and right on the second fixed block without affecting the tilt of the second U-shaped fastener. The cooperation of the second sliding groove and the second sliding frame ensures the stability of the second U-shaped fastener during fine adjustment.

[0014] Furthermore, the second adjusting mechanism includes a second adjusting rod, a second adjusting screw, and a second fastening screw. The second fixing block has a through groove, one end of which is located within a second sliding groove. One end of the second adjusting rod is rotatably connected to the through groove, and the other end has an operating disc. The second adjusting rod has a third screw hole in its middle section, and the second adjusting screw is threaded into the third screw hole. One end of the second adjusting screw passes through a second long slot and is located within a second sliding frame, with a limiting block. The other end passes through the operating disc and has a third limiting disc. The second adjusting screw has a fourth screw hole in its middle section, and the second fastening screw is threaded into the fourth screw hole. One end of the second fastening screw passes through the limiting block and is located within a second sliding frame, with a fourth limiting disc. The other end passes through the third limiting disc and has a third handle. The limiting block is rectangular and is used to prevent the second adjusting screw from rotating.

[0015] Through the above further solution, rotating the second adjusting rod via the operating panel can drive the second adjusting screw to move. When the limiting block on the second adjusting screw moves towards the bottom of the second slide groove, the limiting block, in conjunction with the bottom of the second slide groove, can clamp the second slide frame. When it is necessary to adjust the second U-shaped fixing member, the limiting block on the second adjusting screw moves towards the opening of the second slide groove. When it moves to the required distance, rotating the third handle drives the fourth limiting plate to move via the second fastening screw. When it is necessary to adjust the height of the second U-shaped fixing member, the fourth limiting plate moves towards the limiting block, thereby adjusting the height of the second U-shaped fixing member. When fixing the second U-shaped fixing member, the fourth limiting plate moves away from the limiting block, so that the limiting block abuts against the inner side of the second slide frame and the fourth limiting plate abuts against the second U-shaped fixing member, thereby locking the second slide frame and preventing the second slide frame from moving downward.

[0016] Furthermore, a through hole is provided at the connection end between the fixed L-shaped support and the movable L-shaped support. One end of the movable L-shaped support is slidably connected in the through hole. Track grooves are provided on both opposite sides of the movable L-shaped support. A boss that matches the track groove is provided in the through hole. The boss is slidably connected to the track groove. A first fixing knob for fixing the movable L-shaped support is threadedly connected to the side of the fixed L-shaped support with the through hole.

[0017] Through the above-mentioned further solutions, the cooperation between the rail groove and the boss ensures that the movable L-shaped support can move accurately along a straight path. The movable L-shaped support can be easily locked or released by rotating the first fixing knob, making the adjustment of the position of the movable L-shaped support very convenient and quick.

[0018] Furthermore, the support mechanism includes a strut, a connecting plate, and fasteners. The bracket has a connecting hole, and the strut is slidably connected in the connecting hole. The upper end of the strut has a threaded groove. One end of the connecting plate has a long sliding groove, and the other end is fixedly connected to a support plate. The fastener has a screw, which passes through the long sliding groove and is threadedly connected to the threaded groove. The width of the long sliding groove is smaller than the diameter of the strut, and the diameter of the fastener is the same as the diameter of the strut. The bracket has a second fixing knob threadedly connected to it for fixing the strut.

[0019] Through the above-mentioned further solutions, the support plate can be flexibly adjusted in the vertical and horizontal directions by sliding the support rod in the connecting hole and moving the connecting plate on the support rod through the long sliding groove, so as to adapt to the needs of different patients and the requirements of surgical positions.

[0020] Furthermore, it also includes a connecting mechanism, on which the fixed L-shaped support is fixedly installed.

[0021] With the above further solution, the fixed end of the connecting mechanism is fixedly connected to the hospital bed, so that the fixed L-shaped support can be connected to the hospital bed.

[0022] In summary, the head support for craniocerebral surgery provided by this utility model has the following technical effects:

[0023] The patient's head can be fixed on both sides by fixing the first U-shaped fixation piece on the fixed L-shaped support and moving the second U-shaped fixation piece on the movable L-shaped support. The first adjustment mechanism and the second adjustment mechanism can be used to fine-tune the first U-shaped fixation piece and the second U-shaped fixation piece respectively, so that the first U-shaped fixation piece and the second U-shaped fixation piece can fix the patient's head while improving the patient's comfort, and can enable the doctor to better perform the operation by fine-tuning during the operation.
