UBE surgical tools-UBE bone hammer

Structural features and advantages
Size adapted to UBE surgery
The size of the UBE bone hammer is designed to adapt to the operating environment of UBE surgery. It usually has a small shape and can easily enter the spinal surgical area through the UBE surgical channel. This size design will not cause excessive pressure on the surrounding tissues, and it is convenient to operate in a relatively narrow spinal space. For example, when used in the intervertebral foramen and interlaminar space of the cervical, thoracic or lumbar spine, it can flexibly cooperate with other surgical instruments to complete the task.
Appropriate weight and material
The weight of the bone hammer is moderate, which can provide sufficient percussion force for bone processing, but it will not be difficult to control due to excessive weight. Its material is generally made of high-quality medical metal materials with good strength and corrosion resistance. This allows the bone hammer to maintain its performance after multiple uses, and will not be easily damaged due to stress during the percussion process. At the same time, it also ensures safety during the operation and avoids harm to patients due to instrument quality problems.
Ergonomic handle design
The handle part often adopts an ergonomic design, which is more comfortable for doctors to hold. During long surgical procedures, a good handle design can reduce hand fatigue and enable doctors to more accurately control the direction and force of the tapping. For example, the shape of the handle may fit the curvature of the palm, and the surface may have a non-slip texture to ensure that there will be no accidents such as slipping during use.
Application scenarios in UBE surgery
Vertebral treatment application
Laminectomy assistance: When performing laminectomy in UBE surgery, the UBE bone hammer can be used in conjunction with the osteotome. After the osteotome is placed on the edge of the lamina to be removed, the osteotome is gently tapped with a bone hammer so that the osteotome can gradually chisel open the lamina. For example, in surgery for lumbar spinal stenosis, the osteotome and bone hammer are introduced through the UBE channel to perform segmented resection of the lumbar lamina to expand the volume of the spinal canal and reduce pressure on the nerves.
Facet joint treatment: When treating the facet joints of the spine, the bone hammer can be used to assist in adjusting the position of the facet joints or removing some bone. For some patients who require spinal fusion surgery, proper treatment of the facet joints is necessary. The bone hammer and the bone chisel can accurately remove part of the bone in the facet joint, create suitable conditions for the implantation of the fusion device, and ensure stability and safety during the operation.
Application of fracture reduction
In the UBE surgical treatment of spinal fractures, the bone hammer plays a key auxiliary role. If the fracture fragment is displaced, the doctor can use the bone hammer in conjunction with other reduction instruments, such as the top rod, to gently tap and reduce the fracture fragment. For example, in thoracic fracture surgery, the reduction instrument and the bone hammer are placed through the UBE channel. According to the specific situation of the fracture, the fracture fragment is tapped in a targeted manner to restore it to its normal anatomical position, creating a good foundation for subsequent fixation and healing.
Operation precautions and skills
Operation precautions
Precise positioning is essential: Before using the UBE bone hammer, the exact position of the tapping target must be determined through endoscopic observation. Because there are important tissues such as nerves and blood vessels around the spine, once the tapping position is deviated, serious damage may occur. Therefore, it is necessary to ensure that the osteotome or other instruments that cooperate with it are placed in the correct bone position, and always pay attention to the relative position of the instrument and the surrounding tissue during the tapping process.
Control the force of the tapping: The force of the tapping should be reasonably controlled according to the hardness, thickness of the bone and the purpose of the operation. Excessive force may cause bone fragmentation, damage to surrounding tissues or damage to surgical instruments. When approaching sensitive areas such as nerves and blood vessels, it is even more important to use a gentle tapping method to avoid indirect damage to these tissues caused by vibration waves.
Pay attention to the coordination of instruments: Bone hammers usually need to be used in conjunction with other surgical instruments (such as osteotome), and it is necessary to ensure that the connection between these instruments is firm and the cooperation is tacit. Before the operation, check whether the connection part of the instrument is normal to avoid loosening or falling off of the instrument during the tapping process.
Operation skills
Selection of tapping angle: According to the anatomical structure of the surgical site and the direction of the bone to be treated, choose a suitable tapping angle. For example, during laminectomy, the angle of tapping the osteotome should be as perpendicular to the surface of the lamina as possible, so that the osteotome can cut into the bone more effectively and reduce the dispersion of force. At the same time, combined with endoscopic observation, the tapping angle should be adjusted in time according to the reaction of the bone and the progress of the instrument.
Increase force gradually: When you start to tap, use a light force and observe the bone's reaction and the instrument's penetration. If the bone is hard and you need to increase the force, you can use a gradual approach, increasing the force slightly each time while paying close attention to the surrounding tissue. This gradual tapping method can effectively avoid unexpected situations caused by sudden excessive force.
