Multifunctional visual prevertebral soft tissue separation bone knife

Abstract

The invention relates to a multifunctional visual prevertebral soft tissue separation bone knife. The multifunctional visual prevertebral soft tissue separation bone knife is provided with a knife body, a handle, a composite catheter, an illumination light source, a visual system and a negative pressure suction device; the knife body is arranged on the front portion of the knife handle, and the composite catheter is arranged in the knife body and the knife handle; the illumination light source, the visual system and the negative pressure suction device are connected with the composite catheter separately. The separation bone knife has the advantages that the bone knife is integrated with an endoscope and a suction tube, the illumination light source and the visual system are utilized, the advancing direction of the bone knife can be observed in real time, important blood vessels, nerves and organs in front of the vertebral body are prevented from being accidentally injured in the advancing process of the bone knife, and the operation risk is reduced; the bone knife is designed in a flat type, prevertebral soft tissue can be blocked behind the bone knife, the prevertebral soft tissue, the organs, the important blood vessels and the nerves are protected, and the bone knife is matched with a bone chisel in use so that the safety coefficient of the vertebral body removal operation can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional visible prevertebral soft tissue separation osteotome. Background technique [0002] In clinical practice, kyphoscoliosis, old vertebral fractures, tumors, and congenital hemivertebrae deformities often require en-bloc en bloc resection or block resection of the vertebral body. For viscera and soft tissues bonded side by side, at present, operators often cannot separate prevertebral soft tissues under direct vision during posterior surgery. How to minimize the damage to prevertebral soft tissues and viscera and intraoperative bleeding on the The technique and experience of the surgeon put forward extremely high requirements. The surgeon needs to be very familiar with the anatomical structure of the front, be able to control the use of force well, and have a high hemostasis technique. However, this kind of operation is often easy to damage the intern...

AI Technical Summary

Problems solved by technology

However, the bone knife can only illuminate the operation area, and cannot further observe the internal state, so that nerves, blood vessels or organs are injured during the operation.

[0006] Therefore, there is an urgent need for a soft tissue separation osteotome that can look directly at the operation area, facilitate separation and push away soft tissues such as prevertebral viscera, important blood vessels, and nerves, and find bleeding points in time and assist hemostasis. The knife has not been reported yet
