Description

Technical Field

[0001] The utility model relates to the technical field of medical headrests, and particularly relates to a headrest for limiting the head of a patient during interventional surgery. Background Technique

[0002] Neurology is a secondary discipline related to nerves, mainly admitting patients with head diseases such as cerebrovascular diseases (cerebral infarction, cerebral hemorrhage, migraine, encephalitis, etc.). Patients with craniocerebral injuries need to have surgery on the skull. When operating on the head, it is necessary to fix the head to achieve the optimal surgical effect. At this time, a headrest for limiting position is required.

[0003] Most of the current headrests for limiting position have a single structure and rely on driving two splints to clamp both sides of the head. When the patient needs to have surgery in the lateral position, the clamping position of the splints is not adjustable, which is likely to cause adverse conditions such as squeezing injury to the face and poor breathing, and the practicability is poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a headrest for limiting the head of a patient during interventional surgery to solve the above problems, as described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A headrest for limiting the head of a patient during interventional surgery provided by the utility model includes a base. An activity groove is opened in the middle of the base along the width direction thereof. C-shaped frames are provided on both sides of the base. And an adjusting component one for driving the two C-shaped frames to approach or move away from each other is arranged in the activity groove. Docking blocks are fixedly connected to the upper ends of the two C-shaped frames. C-shaped bottom plates are arranged on the opposite sides of the two docking blocks. And a plugging component for adjusting the height position of the C-shaped bottom plates is arranged on the docking blocks. Ring-shaped plates are slidably connected to the opposite sides of the two C-shaped bottom plates. And an adjusting component two for adjusting the position of the ring-shaped plates is arranged at the end of the ring-shaped plates.

[0007] When using the above headrest for limiting the head of a patient during interventional surgery, fix the base to the head of the operating bed, then let the patient take the supine or lateral position. Adjust the height of the C-shaped bottom plates and the ring-shaped plates through the plugging component. Then drive the ring-shaped plates to horizontally move at the ends of the C-shaped bottom plates through the adjusting component two. After moving to the appropriate position, the adjusting component one drives the two C-shaped frames to approach each other, so that the two ring-shaped plates clamp both sides of the head, which not only avoids damage to the face during clamping but also ensures smooth breathing.

[0008] Preferably, the surface of the base is wrapped with a high-density sponge pad, and one end of the high-density sponge pad is higher than the other end. A ring-shaped pad is fixedly connected to the surface of the ring-shaped plate.

[0009] Preferably, the first adjusting component includes a mounting block fixedly connected to the middle of the movable groove. A bidirectional screw rod is rotatably connected to the middle of the mounting block. Square nuts are threadedly connected to both sides of the bidirectional screw rod, and the square nuts are in clearance fit with the inner wall of the movable groove. The lower ends of the two U-shaped frames are respectively fixedly connected to the two square nuts.

[0010] Preferably, the plugging component includes a plug rod fixedly connected to the middle of the U-shaped bottom plate. A number of positioning holes adapted to the plug rod are formed in the docking block.

[0011] Preferably, the cross-sections of the plug rod and the positioning holes are both designed as regular hexagons. A magnetic block is fixedly connected to the end of the plug rod, and the magnetic block is magnetically connected to the iron docking block.

[0012] Preferably, T-shaped sliding grooves are formed on both sides of the surface of the annular plate. T-shaped sliding blocks slidably connected to the T-shaped sliding grooves are fixedly connected to both ends of the U-shaped bottom plate.

[0013] Preferably, the second adjusting component includes two ear plates fixedly connected to both ends of the annular plate. A threaded rod is rotatably connected between the two ear plates. A threaded sleeve threadedly connected to the threaded rod is fixedly connected to the middle of the U-shaped bottom plate.

[0014] The beneficial effects are as follows:

[0015] The height of the U-shaped bottom plate and the annular plate is adjusted through the plugging component. Then, the second adjusting component drives the annular plate to horizontally move at the end of the U-shaped bottom plate. After moving to a suitable position, the first adjusting component drives the two U-shaped frames to approach each other, so that the two annular plates clamp both sides of the head, which not only avoids damaging the face during clamping, but also ensures smooth breathing. The adjustment position is flexible and changeable, which can better adapt to different patients and improves the practicability. Description of the Drawings

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0023] Refer to Figure 1-Figure 3 As shown, the present utility model provides a headrest for limiting the head of a patient during an intervention operation, which includes a base 1. A movable groove 2 is formed in the middle of the base 1 and runs through along the width direction thereof. C-shaped frames 6 are provided on both sides of the base 1, and a first adjusting component 3 for driving the two C-shaped frames 6 to approach or separate from each other is arranged in the movable groove 2. Docking blocks 7 are fixedly connected to the upper ends of the two C-shaped frames 6. C-shaped bottom plates 8 are arranged on the opposite sides of the two docking blocks 7, and an insertion component 4 for adjusting the height position of the C-shaped bottom plate 8 is arranged on the docking block 7. Ring plates 11 are slidably connected to the opposite sides of the two C-shaped bottom plates 8, and a second adjusting component 5 for adjusting the position of the ring plate 11 is arranged at the end of the ring plate 11.

[0024] As an optional implementation manner, the surface of the base 1 is wrapped with a high-density sponge pad 13, and one end of the high-density sponge pad 13 is higher than the other end. A ring gasket 12 is fixedly connected to the surface of the ring plate 11, which can make the contact between the head and the base 1 more comfortable. At the same time, a leather outer cover can be arranged on the surfaces of the high-density sponge pad 13 and the ring gasket 12 to avoid contamination caused by dirt. The high-density sponge pad 13 with a high-low setting can effectively support the neck for different positions such as supine and lateral lying, making it more comfortable.

[0025] Refer to Figure 2As shown in the figure, the first adjusting component 3 includes a mounting block 3c fixedly connected to the middle of the movable slot 2. A bidirectional screw 3a is rotatably connected to the middle of the mounting block 3c. Square nuts 3b are threadedly connected to both sides of the bidirectional screw 3a, and the square nuts 3b are in clearance fit with the inner wall of the movable slot 2. The lower ends of the two U-shaped frames 6 are respectively fixedly connected to the two square nuts 3b. By rotating the bidirectional screw 3a, the two square nuts 3b can be driven to approach or move away from each other at the same time, so as to drive the two annular plates 11 through the U-shaped frames 6 to complete the clamping of the head.

[0026] Referring to Figure 3 As shown in the figure, the plugging component 4 includes a plug rod 4a fixedly connected to the middle of the U-shaped bottom plate 8. A plurality of positioning holes 4b adapted to the plug rod 4a are formed in the docking block 7. The cross-sections of the plug rod 4a and the positioning holes 4b are both designed as regular hexagons. A magnetic block 4c is fixedly connected to the end of the plug rod 4a, and the magnetic block 4c is magnetically connected to the iron docking block 7. By inserting the plug rod 4a into the positioning holes 4b at a suitable height, the height adjustment of the U-shaped bottom plate 8 can be completed. At the same time, the edges of the hexagon can prevent the U-shaped bottom plate 8 from rotating, and the magnetic block 4c can prevent the plug rod 4a from falling off by magnetic force, and the adjustment process is quick and convenient.

[0027] Furthermore, T-shaped chutes 9 are formed on both sides of the surface of the annular plate 11. T-shaped sliders 10 slidably connected to the T-shaped chutes 9 are fixedly connected to both ends of the U-shaped bottom plate 8, which can make the relative movement between the annular plate 11 and the U-shaped bottom plate 8 more stable and smooth.

[0028] As an optional implementation manner, the second adjusting component 5 includes two ear plates 5a fixedly connected to both ends of the annular plate 11. A threaded rod 5b is rotatably connected between the two ear plates 5a. A threaded sleeve 5c threadedly connected to the threaded rod 5b is fixedly connected to the middle of the U-shaped bottom plate 8. By rotating the threaded rod 5b, the threaded sleeve 5c and the U-shaped bottom plate 8 threadedly connected thereto are driven to move horizontally. Since the U-shaped bottom plate 8 is relatively fixed, the horizontal movement effect of the annular plate 11 can be achieved.

[0029] With the above structure, when in use, the base 1 is fixed to the head of the operating bed, and then the patient lies on the back or side. The height of the U-shaped bottom plate 8 and the annular plate 11 is adjusted through the plugging component 4, and then the annular plate 11 is driven to move horizontally at the end of the U-shaped bottom plate 8 through the second adjusting component 5. After moving to a suitable position, the first adjusting component 3 drives the two U-shaped frames 6 to approach each other, so that the two annular plates 11 clamp both sides of the head, which not only avoids damaging the face during clamping, but also ensures smooth breathing.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
