Soft Tissue Grasper MIM Parts

Product Introduction

The utility model, Soft tissue grasper MIM Parts, belongs to the technical field of medical equipment, and in particular relates to a spinal endoscopic medical grasping forceps with the function of adjusting the angle of the forceps head. 

Background technique
With the development of modern spinal surgery technology, minimally invasive, intelligent, digital and precise surgical technology has become the main development direction in the future, and the development of minimally invasive spinal endoscopic technology plays a pivotal role. Minimally invasive spinal endoscopic visualization Compared with traditional open surgery in the treatment of lumbar degenerative diseases, lumbar fusion has significant advantages such as smaller incision, less bleeding, less damage to lumbar structures, faster postoperative recovery, and fewer complications.
In the process of processing the intervertebral space to establish a bone graft bed, there will be some intervertebral disc soft tissue connected to the bone to be cleaned. The tools for cleaning are generally grasping forceps, which are extended from the forceps rod into the intervertebral space to remove the remaining tough soft tissue. Clamping out, in order to improve a wider field of vision, the current minimally invasive spinal endoscopic lenses use wide-angle lenses, which means that the field of view seen through the endoscope is not just in front of the forceps rod, because the grasping forceps can only be along the direction of the forceps. The axial direction of the rod advances or retreats. Therefore, not all of the intervertebral disc soft tissue to be cleaned under the wide-angle lens field of view can be grasped by the grasper. Changing the angle or enlarging the bony tissue channel and destroying the intervertebral bony tissue to allow the clamps to capture all the remaining intervertebral disc tissue to be cleaned will undoubtedly cause damage to the normal bone and soft tissue around the patient's channel.

Technical Realization Elements
1、The purpose of this utility model of Soft tissue grasper MIM Parts is to provide a kind of spinal endoscopic medical grasping forceps with the function of adjusting the angle of the forceps head, so as to solve the problem of the existing grasping forceps proposed in the above background technology during use. Since the grasping forceps can only advance or retreat along the axial direction of the forceps rod, not all the intervertebral disc soft tissues to be cleaned under the wide-angle lens field of view can be grasped by the grasping forceps. The cylinder rod changes the angle to a certain extent in the human body or expands the bony tissue channel and destroys the intervertebral bony tissue so that the clamp can capture all the residual intervertebral disc tissue to be cleaned, so that the normal bone and bone around the patient's channel will be treated. Problems with damage to soft tissue.
In order to achieve the above purpose, the utility model provides the following technical solutions: a spinal endoscopic medical grasping forceps with the function of adjusting the angle of the forceps head, including a fixed handle and a forceps rod, and the front and back of the fixed handle are fixedly installed with a second A hinged block, the outer side of the first hinged block is hinged with a movable handle, the top of the movable handle is fixedly mounted with a second fixed block, the top of the fixed handle is fixedly mounted with a first fixed block, and the fixed handle is away from One end of the handle is fixedly mounted with a connecting pipe, the inner thread of the connecting pipe is hinged with a sleeve rod, one end of the clamp rod is fixedly mounted with a second hinge block, and the outer side of the second hinge block is hinged with a pliers head. The inside of the pliers head is fixedly equipped with pliers teeth, the top outside the pliers head is fixedly installed with a fixing ring, and the inside of the fixing ring is installed with a pulling wire.
Preferably, a first limiting block is fixedly installed on opposite sides of the fixed handle and the movable handle, and a torsion spring is fixedly installed inside the first limiting block.
Preferably, a second limit block is fixedly installed inside the fixed handle.
Preferably, a second fixed block is fixedly installed on the top of the movable handle, and the inner thread of the second fixed block is hinged with a first bolt.

Preferably, the pliers rod is located inside the sleeve rod, and the end of the pliers rod away from the pliers head passes through the connecting pipe and the fixed handle, and is movably installed inside the second fixed block.

2. Compared with the prior art, the beneficial effects of the utility model are:
(1) Adjust the overall angle of the pliers head by setting the pulling wire to pull the pliers head, which solves the problem that the pliers can only advance or retreat along the axial direction of the pliers rod. The pliers head can change the angle to a certain extent or expand the clamping range in the human body, so that the pliers head can capture all the residual intervertebral disc tissue to be cleaned, so as not to cause damage to the normal bone and soft tissue around the passageway of the patient.
(2) By setting multiple teeth inside the pliers head, it is convenient to grab and take out the intervertebral disc tissue to be cleaned, so it will not cause inconvenience to the medical staff due to the problem of grabbing, thus effectively improving the work efficiency. In addition A torsion spring is installed on the opposite side of the fixed handle and the movable handle, and the fixed handle is separated from the movable handle without the need for grip force, so as to avoid the need for medical staff to separate the fixed handle from the movable handle when using it.
