Description
Technical Field
The utility model relates to a connective tissue centre gripping pincers technical field, more specifically relate to a special connective tissue pincers of orthopedics.
Background
Connective tissue is one of the basic tissues of humans and higher animals, and is composed of cells, fibers and extracellular matrix, with macrophages, fibroblasts, plasma cells, mast cells, etc. The fibers include collagen fibers, elastic fibers and reticular fibers, which mainly connect various tissues and organs, and the matrix is a slightly viscous liquid, which fills between cells and fibers, and serves as a medium for metabolism and exchange of substances. When the joint operation is performed, hyperplastic scar tissues and connective tissues such as hypertrophic joint capsules need to be cut off, so that special clamping forceps are needed for clamping.
In the prior art, mainly used clipping pliers for clamping connective tissues such as scar tissues and joint capsules comprise an upper plier arm and a lower plier arm, the upper plier arm and the lower plier arm are hinged through a pin shaft, the front end of the upper plier arm is connected with the upper clamping arm integrated with the upper plier arm, the front end of the lower plier arm is connected with the lower clamping arm integrated with the lower plier arm, and the opposite surfaces of the upper clamping arm and the lower clamping arm are provided with anti-skid stripes corresponding to each other. When the fastening forceps are used for clamping the connective tissues, the user clamps the connective tissues by the upper and lower forceps arms to respectively drive the upper and lower forceps arms like using a common forceps, so as to cut off the connective tissues.
However, the use of the above-described clip for holding connective tissue has the following problems: firstly, the anti-skid stripes are arranged on the opposite surfaces of the upper clamping arm and the lower clamping arm along the respective width directions, so that the contact area between the anti-skid stripes and the connective tissue is large, and the normal connective tissue is easily damaged; secondly, when clamping the connective tissue, the connective tissue can be clamped stably by increasing force, so that the clipping pliers are easy to deform and even fail to bend, the clamping slippage is caused, and the efficiency of the operation is reduced. Therefore, there is a pressing need for a connective tissue forceps for orthopedics department, which can reduce the damage to the normal connective tissue and is not easy to deform.
