Description

Technical Field

[0001] This invention belongs to the field of medical technology, and in particular relates to a head restraint device for detecting cranial lesions. Background Technology

[0002] In pediatric emergency care, head injuries are among the most serious. For children with head injuries, non-cooperation during medical examinations and treatment can significantly increase the difficulty for medical staff. This non-cooperation is mainly manifested in children grabbing at their upper limbs, easily touching the head wound. Traditionally, this problem has been addressed primarily with the assistance of family members or medical staff. CT scans utilize precisely collimated X-ray beams, gamma rays, and ultrasound waves, along with a detector, to perform continuous cross-sectional scans around a specific part of the body. They are characterized by fast scanning time and clear images, and can be used to examine various diseases. During the examination, the patient lies flat on the examination table with their head positioned in the head-support position, and then the examination is performed.

[0003] According to a published head protection device for testing (Publication No.: CN206507364U), it includes a housing, an observation device, a protective device, and a tightening device. The protective device is installed at the front end of the housing, the observation device is installed at the upper part of the housing, and the tightening device is installed inside the housing. The observation device includes a first rotating rod and a first positioning pin. The two ends of the first rotating rod are fixed to the housing by the first positioning pin. Two rotating axes are symmetrically welded on the first rotating rod. Compared with the prior art, the advantages of this utility model are: the protective device is installed at the front end of the housing, which protects the user's head from injury; the tightening device is installed at the front end of the housing, which protects the user's head from injury. Inside the device, a tensioning mechanism secures the user's head within the housing. A first rotating rod is mounted on the housing via positioning pins on both sides, allowing the rod to rotate. However, the combined use of the observation device, protective device, and tensioning mechanism makes it difficult to effectively fix and limit the patient's head. This compromises the stability and fixation of the patient's head during the examination, hindering the doctor's ability to obtain clear and accurate lesion location information. Consequently, it impedes more precise diagnosis and treatment planning, reduces patient comfort during the examination, and increases the likelihood of examination failures or the need for repeat tests due to discomfort. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a head limiting device for detecting craniocerebral lesions. By rotating the handle, the force that drives the reciprocating screw to rotate, in conjunction with the components such as the fixed rod, moving rod, and rotating rod in the fixing device, achieves the function of moving the limiting block by the displacement of the mounting plate, thus solving the existing problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] The present invention is a head restraint device for detecting craniocerebral lesions, including a protective plate, wherein a neck brace is fixedly connected to the top of the protective plate;

[0007] The top of the protective plate is provided with a fixing device, which includes a fixing plate. The side of the fixing plate is fixedly connected to the side of the protective plate. A reciprocating screw passes through the side of the fixing plate. A moving rod is threaded to the circumferential surface of the reciprocating screw. A fixing block is fixedly connected to one end of the moving rod. A rotating rod is rotatably connected to the side of the fixing block. A positioning block is rotatably connected to the end of the rotating rod away from the fixing block. A mounting plate is fixedly connected to the side of the positioning block. A limit block is fixedly connected to the side of the mounting plate.

[0008] Furthermore, a fixed rod passes through the circumferential surface of the reciprocating lead screw, a positioning rod is fixedly connected to the side of the fixed rod, and a support rod is fixedly connected to the end of the positioning rod away from the fixed rod. The above design fixes the head in a specific position and angle step by step, ensuring that the patient's head remains stable and fixed during the testing process.

[0009] Furthermore, the number of fixing blocks is set to several, in pairs, and symmetrical to each other along the vertical central axis of the protective plate. The number of positioning rods is set to two, and symmetrical to each other along the vertical central axis of the support rod. The above design helps patients feel more relaxed and comfortable during the test, reducing the chance of test failure or needing to repeat the test due to discomfort.

[0010] Furthermore, a disinfection device is provided on the top of the protective plate. The disinfection device includes a squeezing rod, one end of which is fixedly connected to the top of a moving rod. A rectangular plate is fixedly connected to the side of the protective plate, and a spring pump is fixedly connected to the side of the rectangular plate. A connecting pipe is fixedly passed through the side of the spring pump, and a nozzle is fixedly passed through one end of the connecting pipe.

[0011] Furthermore, a push rod extends through the top of the spring pump, a partition is fixedly connected to the bottom of the push rod, and a positioning plate is fixedly connected to the inner wall of the spring pump. This design ensures that the appliance is clean and safe every time it is used, reducing the risk of cross-infection.

[0012] Furthermore, a spring is fixedly connected to the bottom of the partition, and the end of the spring away from the partition is fixedly connected to the inner wall of the spring pump. A limit rod passes through the top of the partition, and both ends of the limit rod are fixedly connected to the inner wall of the spring pump. The above design not only improves the hygiene standards of medical devices, but also reduces the chances for medical personnel to come into contact with surfaces that may contain pathogens.

[0013] Furthermore, a steering device is provided on the top of the protective plate. The steering device includes a rotating shaft, the bottom of which is rotatably connected to the top of the protective plate. A gear is fixedly connected to the circumferential surface of the rotating shaft. A rack is slidably connected to the top of the protective plate. A long rod is fixedly connected to one end of the rack, and a handle is fixedly connected to one end of the long rod. A headrest is fixedly connected to the top of the rotating shaft.

[0014] Furthermore, the side of the rack and pinion meshes with the side of the gear, the spring is initially in a relaxed state, and the top of the spring pump is fixedly connected to the feed pipe. The above design is very important when imaging or surgical operations are required at a specific angle to ensure that the head is accurately fixed in the required position and to avoid image blurring or surgical positioning deviation due to inaccurate angle.

[0015] Furthermore, the number of rotating rods is set to two, and they are symmetrical to each other along the vertical central axis of the protective plate. One end of the reciprocating screw is fixedly connected to a throttle. The above design allows for fine adjustment of the head angle to ensure the accuracy of the surgical or treatment target, which is crucial for minimizing the surgical risk for patients and improving the success rate of surgery.

[0016] The present invention has the following beneficial effects:

[0017] 1. This invention utilizes the force of rotating the handle to drive the reciprocating lead screw, which, in conjunction with components such as the fixed rod, moving rod, and rotating rod in the fixing device, achieves the effect of displacing the limiting block through the displacement of the mounting plate. This effectively fixes and limits the patient's head, ensuring that the patient's head remains stable and fixed during the examination. This is crucial for ensuring that doctors can obtain clear and accurate information about the location of lesions, which helps in more accurate diagnosis and treatment planning. It also helps patients feel more relaxed and comfortable during the examination, reducing the likelihood of examination failure or the need for repeated examinations due to discomfort.

[0018] 2. This invention utilizes the force of the moving rod resetting to drive the squeezing rod to shift, which, in conjunction with components such as the connecting pipe, rectangular plate, and positioning plate in the disinfection device, enables the disinfectant water at the top of the spring pump to flow through the notch to the bottom of the spring pump, and then be sprayed out through the nozzle. This achieves the effect of disinfecting the equipment, increases safety, reduces human contact and intervention, improves disinfection efficiency and consistency, ensures that the equipment is clean and safe for each use, reduces the risk of cross-infection, thereby reducing the possibility of human operation and errors, and improving the consistency and reliability of disinfection.

[0019] 3. This invention achieves the effect of rotating the headrest by rotating the rotating shaft through the interaction of the force of pushing the handle to move the long rod and the components such as the rotating shaft, rack and pinion and gear in the steering device. This achieves the effect of fine adjustment of the angle of the patient's head, ensuring that the head is accurately fixed in the required position, avoiding image blurring or surgical positioning deviation caused by inaccurate angle, helping patients feel more relaxed and comfortable during the examination or treatment process, and improving the overall medical experience.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A handle 401 is fixedly connected to one end of the long rod 402. A headrest 406 is fixedly connected to the top of the rotating shaft 404.

[0040] The side of the rack 403 meshes with the side of the gear 405. The spring 308 is initially in a relaxed state. The top of the spring pump 302 is fixedly connected to the feed pipe 303. The above design is very important for situations that require specific angles for imaging or surgical operations, ensuring that the head is accurately fixed in the required position and avoiding image blurring or surgical positioning deviation due to inaccurate angles.

[0041] The number of rotating rods 207 is set to two, and they are symmetrical to each other along the vertical central axis of the protective plate 101. One end of the reciprocating screw 202 is fixedly connected to the handle 203. The above design can finely adjust the head angle to ensure the accuracy of the surgical or treatment target, which is crucial for minimizing the surgical risk to the patient and improving the success rate of the surgery.

[0042] A specific application of this embodiment is as follows: The patient rests their neck on the neck brace 102 and their head on the headrest 406. Rotating the handle 203 causes the reciprocating screw 202 to rotate, which in turn moves the moving rod 205. This movement of the moving rod 205 then moves the fixing block 206, which in turn moves the rotating rod 207. This rotation of the rotating rod 207 then moves the positioning block 208, which in turn moves the mounting plate 209. Finally, this movement of the mounting plate 209 moves the limiting block 212. This effectively fixes and limits the patient's head, helping them feel more relaxed and comfortable during the examination. It reduces the likelihood of examination failures or the need for repeated examinations due to discomfort, and progressively fixes the head in a specific position and angle to ensure... During the testing process, the patient's head remains stable and fixed. After the test is completed, the moving rod 205 resets, causing the squeezing rod 301 to shift. The shifting squeezing rod 301 then compresses the push rod 304 at the top of the spring pump 302, causing the push rod 304 to move the partition 305 downwards. A notch appears on the side of the positioning plate 306, allowing the disinfectant at the top of the spring pump 302 to flow through the notch to the bottom of the spring pump 302 and then be sprayed out through the nozzle 310. This achieves the disinfection of the instrument, increases safety, ensures that the instrument is clean and safe for each use, and reduces the risk of cross-infection. This not only improves the hygiene standards of medical instruments but also reduces the opportunity for medical personnel to come into contact with surfaces that may contain pathogens. It ensures that medical instruments are effectively disinfected before each use, thereby reducing the possibility of human error and improving the consistency and reliability of disinfection.

[0043] By pushing the handle 401, the long rod 402 is displaced, which in turn causes the rack 403 to move. The rack 403 then rotates the gear 405, which in turn rotates the rotating shaft 404. The rotating shaft 404 then rotates the headrest 406, thus achieving a fine adjustment of the patient's head angle. This is crucial for situations requiring specific angles for imaging examinations or surgical procedures, ensuring the head is precisely fixed in the desired position and avoiding blurred images or surgical positioning deviations due to inaccurate angles. This ensures the precision of the surgical or treatment goals, allowing doctors to obtain clear and accurate images, which helps in the correct diagnosis and assessment of the patient's condition.
