Guiding and positioning operation tool for nucleus insertion of seawater pearl shell

Abstract

The invention discloses a guiding and positioning operation tool for nucleus insertion of a seawater pearl shell. The guiding and positioning operation tool comprises a diamond-shaped handle, a guider, a positioner, a positioner bracket and a guider bracket, wherein the guider is an elliptic body; the positioner is a round body; and one end of the diamond-shaped handle is connected with the guider through the guider bracket, and the other end of the diamond-shaped handle is connected with the positioner through the ladder-shaped positioner bracket. The guiding and positioning operation tool is adopted to perform nucleus insertion for pearl culture, so that injured soft tissues and surface tissues of an implanted nucleus can be reduced, a wound of an operated mother shell is quickly healed, the physical ability of the operated mother shell is satisfactorily recovered, the survival rate is increased, and the nucleus split rate is reduced; and after small cell pieces and the nucleus are transplanted into a host shell body for culture, a nacrum is formed, the nacrum secreting speed is accelerated, the quality of pearls is improved, and the yield of the pearls is increased, so that the key technical problem of nucleus insertion for pearl culture is effectively solved.

Description

technical field [0001] The invention relates to a surgical tool for guiding and positioning seawater pearl oyster insertion. Background technique [0002] The surgical tools for seawater pearl oyster insertion and nucleation mainly include opener, slicing knife, tweezers, incision knife, channel guide pin, flat needle, nuclei feeder and slicer needle, and nuclei insertion platform, etc. The insertion nucleus of the pearl oyster is on both sides of the constrictor muscle on the soft body. Before inserting the core, put the female oyster with the plug mouth, the right shell upward, and the left shell downward on the core inserting platform, gently wipe off the sticky substances near the core and shell mouth with cotton, and then black and white on the muscle of the foot. Use an open knife to make an incision at the junction, the size is just enough to feed the bead nucleus, and the depth is just enough to cut the epidermis. Then use the channel needle to insert the direction...

AI Technical Summary

Problems solved by technology

When inserting the nucleus, directly insert the channel needle into the epidermis at the incision in the direction of the nucleus to make a channel, and then use the nucleus feeder to send the bead nucleus along the channel to the nucleus position. When the channel needle is directly inserted into the epidermis When the channel is opened, the tissue in the epidermis has been damaged. At the same time, the channel guide needle held by the operator in the wrong direction will cause the channel to be opened to pierce the epidermis and the operation will fail. Even if the epidermis of the channel is intact, insert The bead nucleus will aggravate the trauma of the tissue in the epidermis, especially when the inserted bead nucleus does not reach the nucleus position, the bead nucleus is easy to prolapse and the small pieces of cells flow out; and when the inserted bead nucleus enters the nucleus position deeply, the bead nucleus The nucleus will severely squeeze the organs of the soft body and cause the death of the operated mother oyster

Therefore, when the above operation tools are used to insert the nucleus, not only the epidermal tissue will be damaged or ruptured, but also the internal tissue of the soft body will be injured, resulting in inflammation or slow wound healing of the operated mother oyster, resulting in a high rate of nuclear spit and increased mortality.
