Claw-shaped sternum fixator

Abstract

The invention discloses a claw-shaped sternum fixator. The claw-shaped sternum fixator comprises an inner claw gripping plate and an outer claw gripping plate, the outer claw gripping plate is provided with a socket with a tooth socket portion, the inner claw gripping plate is provided with a tooth inserting portion which is matched with the tooth socket portion through insertion, the inner claw gripping plate achieves insertion connection through the matching of the tooth inserting portion and the tooth socket portion, first saw teeth are arranged inside the tooth socket portion, the tooth inserting portion is provided with second saw teeth matched with the first saw teeth, the inner claw gripping plate is further provided with a lock loosening fastener and a lock loosening hole, the lock loosening fastener and the lock loosening hole are matched with each other, and the lock loosening fastener is hinged to the inner claw gripping plate; when the lock loosening fastener moves relative to the inner claw gripping plate to enter into the lock loosening hole in a matching mode, the first saw teeth of the tooth socket portion are engaged with the second saw teeth of the tooth inserting portion to facilitate the tight fit of the inner claw gripping plate and the outer claw gripping plate. The claw-shaped sternum fixator can be locked, fixed and opened without any auxiliary tools, reduces operation time, wins precious time for rescue of patients, improves achievement ratios of operation, can be used for conveniently adjusting folding width of thoracotomy, is convenient and stable in fixation.

Description

technical field [0001] The invention relates to a claw-shaped sternum fixer, which belongs to the field of medical equipment and is used for fixing the sternum after thoracotomy in cardiothoracic surgery. Background technique [0002] At present, in the treatment that requires thoracotomy, the operation of the sternal closure fixer used in the chest closure operation is still not ideal, and the second thoracotomy cannot be performed immediately on any occasion without special equipment.

[0002] At present, in the treatment that requires thoracotomy, the operation of the sternal closure fixer used in the chest closure operation is still not ideal, and the second thoracotomy cannot be performed immediately on any occasion without special equipment. After being used in the hospital, when the patient has arrived in the ICU of the ward, the thoracotomy is required immediately due to a sudden illness. If the patient is moved to the operating room, the time is not allowed, and the thoracotomy must be taken immediately for rescue. The opened instruments are in the operating room, and they have not even been sterilized. If there is a claw-shaped sternum fixer that can be opened without any tools, it will win valuable time for rescuing patients.

Cardiac surgery is generally carried out in large specialized hospitals with high technical level. When the patient is discharged from the hospital and returns to the local area, if there is an emergency, it is too late to go to the original hospital for treatment.
