When examining the patient, it is generally necessary to examine the patient's joints, pupils, touch, etc., and then use tools such as percussion hammers, flashlights, styluses, etc.
[0003] After checking, the public (announcement) number: CN219048604U discloses a multifunctional nursing inspector for neurosurgery, "including a hammer body, a first hammer head and a second hammer head are respectively provided at both ends of the hammer body, the first hammer head is fixedly connected to the hammer body, a first cavity is provided in the hammer body, the second hammer head is provided in the first cavity, a second cavity is provided in the second hammer head, a third hammer head is provided in the second cavity, a slider is fixedly provided on the third hammer head, a slide groove matching the slider is provided on the hammer body and the second hammer head, the top of the slider passes through the slide groove and extends to the outside of the hammer body, a hammer handle is vertically provided at the bottom of the hammer body, and the three hammer heads are of different sizes through the arrangement of the first hammer head, the second hammer head and the third hammer head, etc., which is convenient for selection according to actual needs during use, and the first hammer head, the second hammer head and the third hammer head are all made of rubber, which play a buffering role during percussion to avoid harm to the human body and other protective effects";
[0004] In the above-mentioned comparative documents, when testing the patient's joints, different hammer heads are set to test the patient, but the percussion hammer is usually tested manually by the doctor, and the percussion force of the percussion hammer cannot be accurately controlled. When the percussion force is too small, the patient's joints cannot be effectively tested. When the percussion force is too large, the patient's joints are easily painful or damaged, so that the doctor needs to repeatedly test the patient's joints;
[0005] In order to solve the above-mentioned problems, the present application proposes a neurosurgery inspection device. Utility Model Content

It can be adjusted for people of different ages, so that the hammer head can better detect patients and avoid damage to patients caused by the hammer head during detection.
[0020] The hammer head is limited by a limiting ring to prevent the hammer head from escaping from the limiting frame during detection. The handle can be connected to the connecting rod to drive the hammer body to work. The anti-slip groove on the outer wall of the handle increases the friction between the hand and the handle to prevent the device from escaping from the hand. The searchlight installed on the handle can be used to detect the patient's eye nerves. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0027] Reference Figure 1-3The neurosurgery inspector comprises a hammer body 1, both sides of which are fixedly connected to a limit frame 2, a moving groove 3 is provided on the outer wall of the hammer body 1, and a limit groove 4 is provided on the hammer body 1 through the moving groove 3. A sliding plate 5 is slidably connected to the inner wall of the hammer body 1, and a spring 8 is fixedly connected to the sliding plate 5 on the side close to the limit frame 2, and an extrusion plate 9 is fixedly connected to the end of the spring 8 away from the sliding plate 5, and a hammer head 10 is attached to the side of the extrusion plate 9 away from the spring 8. By moving the sliding plate 5, the sliding plate 5 is squeezed on the spring 8, so that the spring 8 contracts inside the hammer body 1, and the squeezing force of the squeezing plate 9 driven by the spring 8 to the hammer head 10 can be increased, so that the force required for the hammer head 10 to rebound during detection can be adjusted, so as to adapt to patients of different ages and avoid excessive force to cause damage to the patient.
[0028] Reference Figure 2 The outer wall of the sliding plate 5 is fixedly connected with a fixed block 6, and the side of the fixed block 6 away from the sliding plate 5 is fixedly connected with a moving ball 7. The moving ball 7 drives the fixed block 6 to move inside the moving groove 3, so that the sliding plate 5 moves inside the hammer body 1 following the fixed block 6, so that the moving ball 7 can drive the fixed block 6 to be limited and fixed in different limit grooves 4, thereby avoiding displacement of the fixed block 6 and affecting the detection effect of the device.
[0029] Reference Figure 2 A contraction groove 11 is provided on the inner wall of the limit frame 2, and a limit ring 12 is fixedly connected to the outer wall of the hammer head 10. The inner wall of the contraction groove 11 is adapted to the outer wall of the limit ring 12, and the limit ring 12 is installed on the end of the hammer head 10 close to the limit frame 2, so that the hammer head 10 can move in the contraction groove 11 provided inside the limit frame 2 through the limit ring 12, and the hammer head 10 can be limited by the limit ring 12 to prevent the hammer head 10 from falling during the detection process.
[0030] Reference Figure 2-3 The limiting grooves 4 are arranged in a linear array on the outer wall of the movable groove 3. By opening a plurality of limiting grooves 4, the spring 8 can be adjusted to different degrees, so that the spring 8 drives the extrusion plate 9 to produce different extrusion forces on the hammer head 10, so that the force required for the hammer head 10 to rebound during detection is different, so that the device can be suitable for patients of different ages and can effectively protect the patients.
[0031] Reference Figure 1 and Figure 4 The outer wall of the hammer body 1 is fixedly connected with a connecting rod 13, and the end of the connecting rod 13 away from the hammer body 1 is fixedly connected with a handle 14. The handle 14 is connected to the hammer body 1 through the connecting rod 13. The connecting rod 13 is fixed to the center of the outer wall of the hammer body 1, so that the handle 14 can effectively drive the hammer body 1 to operate under the connection of the connecting rod 13, so that the device can detect patients with the hammer body 1.
[0032] Reference Figure 1 and Figure 4 A plurality of anti-skid grooves 15 are provided on the outer wall of the handle 14, and a searchlight 16 is provided on the end of the handle 14 away from the connecting rod 13. The plurality of anti-skid grooves 15 provided on the outer wall of the handle 14 can increase the friction between the doctor and the handle 14 through the anti-skid grooves 15 when the doctor holds the handle 14, which can effectively prevent the handle 14 from sliding during the detection process. The searchlight 16 installed at one end of the handle 14 can simultaneously detect the patient's ocular nerve response.
[0033] Working principle: The moving ball 7 drives the fixed block 6 to move along the moving groove 3. When the fixed block 6 moves to the specified position, the moving ball 7 is rotated to make the moving ball 7 enter the inside of the limiting groove 4 for limiting and fixing. When the fixed block 6 moves, it drives the sliding plate 5 to move inside the hammer body 1, so that the spring 8 can be squeezed by the sliding plate 5, so that the spring 8 shrinks inside the hammer body 1, thereby increasing the squeezing force of the squeezing plate 9 driven by the spring 8 on the hammer head 10, so that the rebound force of the hammer head 10 during detection is adjusted. When a child uses it, the spring 8 is stretched to reduce the squeezing of the hammer head 10 by the spring 8, so that the child's legs can be prevented from receiving excessive force during detection. The friction of the handle 14 is increased by the anti-slip groove 15 to prevent the device from falling off during detection. The installed searchlight 16 can be used to detect the patient's ocular nerves.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
