Description

Vertebra scope hemostatic forceps

Technical Field

The utility model belongs to the field of medical equipment, specifically a vertebra scope hemostatic forceps.

Background

With the development of the scientific and technological level and endoscopic instruments in the 80 s of the 20 th century, orthopedists began to use endoscopic techniques for spinal surgery, and after the 90 s of the 20 th century, the endoscopic spinal surgery techniques were developed in great length, and techniques having practical value in clinical practice at present include endoscopic-assisted lumbar posterior or lateral posterior artificial intervertebral disc discectomy, laparoscopic-assisted lumbar lesion removal, and thoracoscopic-assisted thoracic lesion removal.

When carrying out the orthopedics of wicresoft or painful branch of academic or vocational study operation, the condition that patient's bone portion bleeded occasionally can appear, medical personnel are when carrying out minimal access surgery's hemostasis among the prior art, generally adopt following technique, when appearing blood in the endoscope field (more than 2 ml), medical personnel can utilize medical cotton earlier to carry out the hemostasis operation to patient's bleeding position, stop the operation at once this moment, use hemostatic cotton hemostasis by compression 20-30 minutes, when patient's hemorrhage volume reduces in the endoscope field, medical personnel utilize the hand to carry out moulding to bone wax (because bone wax needs moulding and conveying, so can't fill in bone wax hemostasis in time according to the information of bleeding that obtains earlier stage at once when the field of vision disappears), fill in patient's position along the tube sheath passageway of endoscope afterwards and stanch.

The utility model discloses the people is as painful branch of academic or vocational study chief doctor, in-process discovery prior art in the patient of long-time treatment has following drawback, when the patient bleeds, the endoscope field of vision is fuzzy can't carry out bone wax hemostasis so must utilize medical cotton earlier to stanch, the patient crouches in the operation table for a long time this moment, can make patient local infection rate increase, nerve oppression increases, more serious leads to postoperative nerve dysfunction or even leads to the incomplete misery that has prolonged patient's operation even, if the patient can't effectively stanch after 30 minutes, can turn into open operation with minimal access surgery (local anesthesia becomes general anesthesia this moment), the while is increaseed the patient injury, these injuries are difficult to heal even. Even if the amount of bleeding of a patient is reduced by the medical cotton and the medical staff obtains the visual field again, the bone wax needs to be kneaded and shaped by the medical staff, and the endoscope is usually stuck during transmission of the bone wax, so that the obtained visual field is lost again.
