AI Technical Summary
In the existing technology, the ulnar nerve at the olecranon of the patient's ulna is easily damaged due to prolonged pressure during surgery, which is more obvious in patients with thin bodies. In addition, ordinary cotton pads lack elasticity and standardized operations make it difficult to effectively prevent such injuries.
A rectangular pad made of soft material is designed with a slot and a fixing strap, which is used to cushion the ulna and humerus in front and behind the patient's olecranon. The slot and the fixing strap cooperate to ensure that the olecranon is separated from the handrest, thereby reducing nerve compression.
It effectively prevents ulnar nerve injury, has a simple structure, is easy to use, facilitates standardized operation and management, and improves surgical quality.

TECHNICAL FIELD
[0001] The utility model relates to a medical instrument, especially an auxiliary instrument suitable for surgical treatment, in particular to a pad block capable of preventing ulnar nerve injury. BACKGROUND
[0002] In surgical operation, more operations need patients to be in supine position, prone position, lithotomy position and the like. The arms of the patients in these positions need to be placed on the hand rest plate beside the operating bed. At this time, the ulnar process of the ulna of the patient's arm will be directly attached to the hand rest plate. Since the ulnar nerve at the ulnar process is relatively superficial and lacks muscle and fat protection, the ulnar nerve at this position is prone to injury due to long-term compression.
[0003] At present, in order to avoid the above-mentioned ulnar nerve injury, ordinary medical cotton pads are often used to pad the ulnar process of the patient. However, since the cotton pad lacks elasticity and cannot achieve sufficient decompression, the prevention effect of this method is poor, especially for patients with thin body type, since their own ulnar nerve protection ability is weak, they are more likely to cause ulnar nerve injury due to insufficient decompression. Moreover, this method is not easy to standardize operation, and is easy to affect the protection effect due to the improper operation of the operating room nurse.
[0004] Therefore, it is urgent to improve it in order to better meet the use requirement. CONTENT OF THE UTILITY MODEL

[0018] The utility model will be further explained in connection with the drawings and examples.
[0019] As Figure 1 Indicated.
[0020] A kind of prevent ulna nerve injury's cushion block, including body 1 etc.
[0021] The body 1 is rectangular block, is made of soft material such as silica gel, so that it has certain deformation ability.
[0022] The upper end surface of the body 1 is provided with recessed groove-shaped clamping groove 2.The cross section of the clamping groove 2 is shallow circular arc, and penetrates the body 1 along its axial direction, so as to play the indicating and limiting function, conveniently place the arm of patient near ulna eagle mouth in the clamping groove, ensure to place in place.The clamping groove 2 is located in the central position of the upper end surface of the body 1, for convenience.
[0023] The opposite sides of the body 1 are respectively provided with fixing belts 3. The fixing belts 3 are soft belts and can be curled, one end of which is connected with the body 1 and the other end is a free end. Meanwhile, the free end is provided with a fastening structure, so that the two free ends can be buckled with each other to form a ring structure with the body, so as to be sleeved on the hand rest plate and fix the body.
[0024] The fastening structure can be a double-loop buckle 4 arranged on the free end of one of the fixing belts 3 to form a double-loop buckle waistband structure. In use, the free end of the other fixing belt is wound around the double-loop buckle 4, so that the free ends of the two fixing belts 3 are firmly connected.
[0025] The body 1 is two and used in pairs to pad the ulna and humerus before and after the olecranon of the patient, so that the ulnar nerve at the olecranon is decompressed. Meanwhile, a connecting belt 5 is arranged between the two bodies. The connecting belt 5 is a thin belt with a length of 30-40 cm, and the two ends thereof are connected with the side walls of the bodies respectively, so as to ensure that the two bodies are placed and used in pairs and prevent the accidental scattering of one of the bodies in use.
