Problems solved by technology

Chinese patents CN201320855790.2 and CN201320855796.X respectively disclose a pressurized forceps and spreader forceps, but these two tools are not suitable for minimally invasive surgery, and two tools are required to complete the spreader and pressurization
Chinese patent CN201420388096.9 discloses a minimally invasive percutaneous spinal distractor. The tool is inserted into the incision by two distractor blades to apply distraction to the pedicle screws to complete the distraction. However, the tool needs to be inserted into the human body In this case, the incision will be enlarged, and the tool can only complete parallel propping, which cannot well meet the requirements of minimally invasive surgery, minimal invasiveness, angular propping or pressurization

Abstract

The invention relates to a distraction compression clamp for minimally invasive spine surgery. The compression clamp comprises a left clamping handle, a right clamping handle, a fulcrum, a connecting device and a fixing device, wherein the left clamping handle and the right clamping handle are connected in an X-shape by virtue of the connecting device, and can rotate around the connecting device; a holding part is respectively arranged at the front end of the left clamping handle and the front end of the right clamping handle, and a grasp part is respectively arranged at the rear end of the left clamping handle and the rear end of the right clamping handle; one end of the fixing device is fixedly connected with the rear end part of the left clamping handle, and the other end of the fixing device is blocked to the rear end part of the right clamping handle. The distraction compression clamp can perform angular distraction and compression operations on the vertebral body with a minimally invasive pedicle screw under the condition of not enlarging an existing cut.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a distraction and compression forceps for spinal minimally invasive surgery. Background technique [0002] Minimally invasive spine surgery is more and more favored by patients and doctors because of its small surgical incision, small tissue trauma, less blood loss, and quick postoperative recovery. In minimally invasive spine surgery, the patient's spinal segment is often distracted or compressed. In open surgery, distraction or compression is accomplished by distracting or compressing the pedicle screw with distractor or compression forceps. Chinese patents CN201320855790.2 and CN201320855796.X respectively disclose a compression forceps and a spreader forceps, but these two tools are not suitable for minimally invasive surgery, and two tools are required for expansion and pressure. Chinese patent CN201420388096.9 discloses a minimally invasive percutaneous spinal...
