Drivable spiral progressive low-injury integrated bone puncture needle

Abstract

The invention discloses a drivable spiral progressive low-injury integrated bone puncture needle which comprises a bone puncture needle main body, one end of the main body is provided with a conical tip part, and the other end of the main body is provided with an assembly section with threads; an outer rod handle, a middle rod handle and an inner rod handle are sequentially connected to the assembling section in a screwed mode, and the inner rod handle is arranged to be in an opening type. A connecting mechanism is arranged on the main body and located between the tip part and the inner rod handle, the connecting mechanism comprises a detachable gear, a fixed locking part for limiting the gear and an adjustable clamping part connected to the gear, and the clamping part is used for clamping a sickbed. The percutaneous puncture needle is high in practicability and functionality and can be widely applied to the technical field of percutaneous puncture.

Description

technical field [0001] The invention relates to the field of percutaneous puncture, in particular to a drivable spiral progressive low-damage integrated bone puncture needle. Background technique [0002] Percutaneous puncture vertebroplasty is currently a common surgical method for the treatment of senile osteoporotic compression fractures. It has the characteristics of small trauma, fast recovery, and remarkable effect. However, the puncture system used in clinical surgery usually requires a fine puncture Needle puncture for positioning, then insert the secondary sleeve on the positioning needle, smash it into the bone with a bone hammer, then insert the third-level sleeve on the second-level sleeve, and use the bone hammer to smash again, and put the third-level sleeve into the bone. The tube is smashed into the bone to establish a working channel for bone cement delivery. Multiple punctures may easily cause bone damage on the surface of the puncture point. If a thick pun...

[0002] Percutaneous puncture vertebroplasty is currently a common surgical method for the treatment of senile osteoporotic compression fractures. It has the characteristics of small trauma, quick recovery, and remarkable effect. However, the puncture system used in clinical surgery usually requires a fine puncture Needle puncture for positioning, then insert the secondary sleeve on the positioning needle, smash it into the bone with a bone hammer, then insert the third-level sleeve on the second-level sleeve, and use the bone hammer again to smash the third-level sleeve. The tube is smashed into the bone to establish a working channel for bone cement delivery. Multiple punctures may easily cause bone damage on the surface of the puncture point. If a thick puncture needle is directly used for positioning, because the needle shaft is relatively thick, direct knocking into the bone may cause secondary fractures. Once the puncture is in, the direction is difficult to change, the success rate of puncture is reduced, and the risk of surgery is increased. At the same time, most of the puncture needles are violently smashed into the vertebral body by a bone hammer. Due to old age osteoporosis, it is easy to cause pedicle and vertebra damage to the body, thereby causing risks such as bone cement leakage and spontaneous bleeding
