Description

Technical Field

[0001] The utility model relates to the technical field of skull traction devices, in particular to an adjustable skull traction device. Background Art

[0002] Cervical spine surgery usually has high risks and difficulty and requires delicate operations. During the operation, cervical spinal cord injury may cause quadriplegia or even life-threatening. To reduce these risks, doctors usually perform continuous skull traction during the operation, which helps maintain neck stability, makes the surgical site easier to expose and fix, and helps with joint reduction, thereby reducing surgical risks.

[0003] However, there are some inconveniences in the use of the existing traction devices. For example, the skull traction device with application number CN202221637410.3 is composed of a base and a traction unit arranged on the base. The traction unit includes a fixing part, a bracket, a force-applying part and a traction wire. The traction unit can be adjusted by the lateral position of the bracket on the base, but this can only change the tension of the fixing part. At the same time, the position of the support pillow supporting the head relative to the bed cannot be adjusted, which makes the device unable to adapt to patients of different body types, especially patients with long necks. Since the position of the support pillow relative to the bed cannot be adjusted, the patient cannot extend too much forward to maintain balance, but cannot extend too little to achieve a good traction effect. In addition, for patients with different fat and thin bodies, since the height of the support pillow cannot be adjusted, patients with fat bodies may need to lower their heads to support them on the support pillow, and patients with thin bodies may need to raise their heads to support them on the support pillow. Therefore, the support pillow needs to be adjusted to a suitable position according to the actual conditions of different patients. However, the device lacks such an adjustment function, which can easily cause the support pillow to compress the patient's eyes or cause other injuries to the patient. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an adjustable skull traction device.

[0016] In order to improve the durability and stability of the device, the main frame is made of stainless steel, and the main frame is composed of square tubes with the same cross-sectional specifications. The stainless steel material itself has extremely strong corrosion resistance, which means that even under the conditions of disinfection or contact with body fluids that may corrode other materials, the device can maintain its integrity and durability. The stainless steel square tube has a long service life and does not require frequent replacement, reducing long-term maintenance costs. In addition, due to its shape, the stainless steel square tube has good bending and torsional strength, which is crucial to maintaining the structural stability of the entire skull traction device. This stability ensures that the device can withstand various forces without deformation during use, thereby ensuring the safety of the patient and the treatment effect.

[0017] The beneficial effect of the adjustable skull traction device of the utility model is that: by arranging that the front-to-back position of the first supporting member relative to the first connecting member is adjustable and the upper-lower position of the second supporting member relative to the first supporting member is adjustable, the front-to-back position and the upper-lower position of the entire traction unit can be adjusted, that is, the position of the traction unit relative to the operating table is adjustable, and the height of the traction unit is adjustable, so that the device can be suitable for patients of different body shapes, and the support pillow can be adjusted to a suitable position according to the actual conditions of different patients, thereby avoiding unnecessary pressure or injury to the patient, especially preventing pressure on sensitive parts such as eyes, and significantly improving the safety and comfort of the patient during treatment.
