Description

Technical Field

[0001] This invention relates to the field of neurosurgical technology, specifically to a neurosurgical brain surgery aid device. Background Technology

[0002] Neurosurgery is a branch of surgery that, based on surgery as the primary treatment method, applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related accessory structures such as the skull, scalp, cerebral blood vessels, and meninges, for injuries, inflammation, tumors, deformities, and certain genetic metabolic disorders or functional disorders. It is a highly specialized and sophisticated discipline that primarily treats diseases of the brain, spinal cord, and other nervous systems caused by trauma, such as life-threatening cerebral hemorrhage, brain injuries caused by car accidents, or brain tumors requiring surgical treatment.

[0003] In neurosurgical brain surgery, to maintain the stability of the surgical area, the patient's head needs to be reliably supported and fixed. Usually, a special head fixation device is needed to achieve precise positioning. However, most existing devices cannot synchronously stabilize the patient's torso. If the patient experiences sudden body movement such as coughing during local anesthesia or when the general anesthesia is light, it may cause the body to shift vertically. At this time, the head, as the main support point, will bear significant abnormal stress, which may affect the safety and precision of the operation. Summary of the Invention

The lifting guide column 206 is fixedly installed inside the lifting guide groove 203. The surface of the shoulder width adjustment slide 302 is slidably connected to the inner wall of the shoulder width adjustment slide 302 to support and guide the shoulder width adjustment slide 302. The rotating shaft 207 is rotatably connected to the inside of the shoulder block 202 via a bearing to connect the locking ring 208 and the anti-dislodgement plate 210. The locking ring 208 is fixedly sleeved on the surface of the rotating shaft 207, and the surface of the locking ring 208 has a locking groove to cooperate with the electromagnetic lock 209 for locking. The electromagnetic lock 209 is fixedly installed on the surface of the shoulder block 202 to lock the locking ring 208.

The shoulder width adjustment slide 302 is slidably connected inside the lifting guide seat 201, and there are two shoulder width adjustment slides 302. Adjustable slides 302 are located on both sides of the support base 301 to drive the lifting guide 201 to adjust the shoulder width position according to the patient. A guide seat 303 is fixedly connected to the bottom of the support bed board 101. The support base 301 is located inside the guide seat 303 to support the shoulder width adjusting slide 302. A guide strip 304 is integrally set inside the guide base 303, and guide rails 305 are integrally set on both sides of the shoulder width adjusting slide 302. The inner wall of the guide rail 305 is slidably connected to the surface of the guide strip 304 to ensure that the shoulder width adjusting slide 302 can move along the guide strip 304. 4. A sliding electric telescopic rod 306 is rotatably connected between the support base 301 and the shoulder width adjusting slide 302, so that the extension and retraction of the electric telescopic rod 306 drives the shoulder width adjusting slide 302 to move. The shoulder width adjusting guide post 307 is fixedly inserted into the inside of the support base 301, and the guide post groove 308 is opened in the inside of the shoulder width adjusting slide 302.

[0027] The axillary limiting mechanism includes: an axillary-shoulder distance adjustment seat 401, an axillary support column 402, a buffer sleeve 403, a corrugated tube 404, an axillary-shoulder distance adjustment screw hole 405, an axillary-shoulder distance adjustment motor 406, and an axillary-shoulder distance adjustment screw 407. The axillary-shoulder distance adjustment seat 401 is slidably connected inside the lifting guide seat 201 to support the axillary support column 402. The axillary support column 402 is fixedly inserted into the top of the axillary-shoulder distance adjustment seat 401 to limit the patient's axillary position. The buffer sleeve... 403 is fixedly sleeved onto the surface of the underarm support column 402 to cushion the surface of the underarm support column 402. A bellows 404 is fixedly connected between the underarm / shoulder distance adjusting seat 401 and the lifting guide seat 201 to ensure relative sliding between them while forming a seal. An underarm / shoulder distance adjusting screw hole 405 is opened inside the underarm / shoulder distance adjusting seat 401. The underarm / shoulder distance adjusting motor 4... 06 is fixedly installed inside the lifting guide seat 201 to drive the axillary-shoulder distance adjustment screw 407. The axillary-shoulder distance adjustment screw 407 is fixedly installed at the output end of the axillary-shoulder distance adjustment motor 406 through a coupling, and the surface of the axillary-shoulder distance adjustment screw 407 is threadedly connected to the internal thread of the axillary-shoulder distance adjustment screw hole 405. The rotation of the axillary-shoulder distance adjustment screw 407 drives the relative movement between the axillary-shoulder distance adjustment seat 401 and the lifting guide seat 201. Through the axillary-shoulder distance adjustment seat 401, the axillary support column 402, the buffer sleeve 403, the corrugated pipe 404, the axillary-shoulder distance adjustment screw hole 405, the axillary-shoulder distance adjustment motor 406, and the axillary-shoulder distance adjustment screw 407, the axillary-shoulder distance adjustment motor 406 can drive the distance between the axillary-shoulder distance adjustment seat 401 and the shoulder block 202 during use, so that the axillary-shoulder distance of the two patients is matched, and the axillary-shoulder distance is limited under the patient's armpit by the axillary-shoulder distance support column 402 to prevent the patient from sliding down on the irregular mattress 102.

[0028] Working principle: When in use, open the electromagnetic lock 209 to unlock the locking ring 208, rotate the anti-slip plate 210 to unfold it, then place the patient's shoulder between the shoulder block 202 and the axillary support column 402, then close the anti-slip plate 210 and lock the electromagnetic lock 209 to lock the position of the anti-slip plate 210. Then, adjust the distance between the two lifting guide seats 201 to match the patient's shoulder width. During adjustment, simultaneously activate the two electric telescopic rods 306. When the electric telescopic rods 306 extend, push the shoulder width adjusting slide 302 outward away from the support seat 301, thus increasing the distance between the two lifting guide seats 201. When the electric telescopic rods 306 retract, pull the shoulder width adjusting slide 302 inward towards the support seat 301, thus shortening the distance between the two lifting guide seats 201. This allows the distance between the two lifting guide seats 201 to be matched with the patient's shoulder width by controlling the distance between them. Then, adjust the distance between the shoulder block 202 and the axillary support column 402 to match the patient's axillary-shoulder distance. During adjustment, start the axillary-shoulder distance adjustment motor 406. The axillary-shoulder distance adjustment motor 406 drives the axillary-shoulder distance adjustment screw 407 to rotate. When the axillary-shoulder distance adjustment screw 407 rotates, it pushes the axillary-shoulder distance adjustment seat 401 to slide along the inside of the lifting guide seat 201. This causes the axillary support column 402 to move through the axillary-shoulder distance adjustment seat 401, thereby adjusting the relative distance between the axillary support column 402 and the shoulder block 202. This makes the buffer sleeve 403 close to the patient's armpit, and the buffer pad 211 on the surface of the shoulder block 202 close to the patient's upper shoulder, thereby compressing the patient's movement space. Then, adjust the distance between the anti-slip pad 210 and the irregularly shaped mattress 102 to match the patient's shoulder thickness. During adjustment, start the lifting drive motor 204, which drives the lifting screw 205 to rotate. When the lifting screw 205 rotates, it pushes the shoulder width adjustment slide 302 to slide along the lifting guide column 206. Since the height of the shoulder width adjustment slide 302 remains relatively constant, the lifting drive motor 204 and the lifting screw 205 drive the lifting guide 201 to descend, so that the cushioning pad 211 inside the anti-slip pad 210 comes into contact with the front of the patient's shoulder, thereby limiting the patient's shoulder position.
