The existing guide needle is a traditional solid needle with a small hole at the needle point. The guide needle with the thread is passed through the aponeurosis, then one end of the thread is left at the needle entry point, the other end is pulled out from the needle exit point and the thread is pulled until the central section is positioned at the subcutaneous aponeurosis layer, and finally the guide needle is pulled out. At this in-process of pulling wire, half barb line can pass through the cap aponeurosis fixed point, not only can increase the damage of tissue and bleed, causes the postoperative swelling, still can harm the barb on wire rod surface, influences the stability of hanging the tissue.

Accordingly, to solve the above-described problems, as shown in fig. 1 to 5, an embodiment of the present application provides a galena anchoring trocar, including: a needle body 1 and a needle core; wherein the content of the first and second substances,

the needle body 1 is arranged in an arc shape, a wire inlet hole 4 and a wire outlet hole 5 are formed in the needle body 1 along the bending direction of the needle body 1, the wire inlet hole 4 is communicated with the wire outlet hole 5, and a wire channel (not shown in the figure) is formed;

when the needle body 1 penetrates through the aponeurosis, the wire inlet hole 4 and the wire outlet hole 5 are both positioned on the outer side of the aponeurosis;

a needle core (not shown) is inserted into the wire passage and can be pulled out of the wire passage.

In this embodiment, the trocar for anchoring the aponeurosis mainly comprises a needle body 1 and a needle core, wherein the needle body 1 is a main structure of the trocar, and the trocar is a guide needle for a wire 6, and needs to penetrate into the aponeurosis and then penetrate out of the aponeurosis, so that in order to facilitate puncturing, the needle body 1 is of an arc-shaped structure, and the needle body 1 can more easily penetrate out of the aponeurosis by using the curved radian of the needle body 1. A wire inlet hole 4 and a wire outlet hole 5 are formed in the needle body 1 along the bending direction of the needle body 1, and the wire inlet hole 4 is communicated with the wire outlet hole 5 to form a wire channel. Before use, the needle core is arranged in the wire channel in a penetrating way, the wire inlet hole 4 and the wire outlet hole 5 are in a closed state, and the needle core can pass through the aponeurosis of the hat shape along with the needle body 1. As shown in fig. 6, after the needle body 1 passes through the aponeurosis, whether the passing position is accurate or not is determined, if so, the needle core can be pulled out from the wire channel, the needle core can be pulled out from the direction of the wire inlet 4, and the needle core can also be pulled out from the direction of the wire outlet 5. To facilitate the extraction of the core and the subsequent threading of the wire 6, the wire inlet hole 4 and the wire outlet hole 5 are both located outside the aponeurosis when the needle body 1 is threaded through the aponeurosis.

As shown in fig. 7 to 9, after the withdrawal of the needle core, the needle body 1 forms a hollow needle, the hollow part of which is the wire channel formed by the wire inlet hole 4 and the wire outlet hole 5. Because the wire inlet hole 4 and the wire outlet hole 5 are both located on the outer side of the aponeurosis, an operator can penetrate the wire 6 into the needle body 1 from the wire inlet hole 4 and then pull out the wire 6 from the needle body 1 from the wire outlet hole 5. In the process, the needle body 1 is fixed on the aponeurosis, the wire 6 is penetrated by the wire channel on the needle body 1, and the wire 6 is not in direct contact with subcutaneous tissues, so that subcutaneous bleeding is reduced, and the postoperative swelling recovery period is shortened. Moreover, because the wire 6 does not directly contact subcutaneous tissues, the wire 6 cannot be lost in the process of penetrating, and the damage to the wire 6 caused by the error of the first puncture part and the need of re-puncture is avoided.

As shown in fig. 9, the movement of the wire 6 is stopped when the wire 6 is moved to its centered position under the skin, at which point the wire 6 is already in the set position. The operator can then pull the needle 1 out of the aponeurosis and completely disengage the needle 1 and the wire 6, thus completing the anchoring of the wire 6 to the aponeurosis.

This embodiment has changed the mode that the needle was worn to the tape thread in the past through this cap aponeurosis anchoring trocar, can assist the art person in-process of carving the operation on line, the 6 accurate anchoring of wire rod that will have the barb on the cap aponeurosis to can reduce the tissue damage, alleviate the subcutaneous hemorrhage, alleviate the postoperative swelling, shorten the postoperative convalescence, and reduce the damage to wire rod 6. Therefore, the problems that when the guide needle is used for threading the wire 6 in the related technology, the damage of tissues is easily increased to bleed, the postoperative swelling is caused, the barb on the surface of the wire 6 is damaged, and the stability of suspended tissues is influenced are solved.

The wire entry hole 4 and the wire exit hole 5 should have a diameter slightly larger than the diameter of the wire 6 to be used, in order to facilitate the passage of the wire 6 through the wire passage. To further facilitate threading of the wire 6 into the wire channel, the linearity of the wire channel matches the linearity of the needle 1.

Further, wire rod inlet hole 4 and wire rod exit hole 5 all set up to the round hole, are convenient for the wire rod 6 from wire rod inlet hole 4 from the leisurely to penetrate out from wire rod exit hole 5. Of course, the wire inlet hole 4 and the wire outlet hole 5 may be provided in other shapes, such as an oval shape, in practical use.

Furthermore, the bending radius of the needle body 1 is 2-10 mm. In a preferred embodiment, the needle body 1 has a bending radius of 4mm or 6mm or 8mm, corresponding to the thickness of the human scalp to the aponeurosis. The operator can accurately puncture the aponeurosis layer by selecting the corresponding specification according to different people.

In a general threading process with a wire, an operator can use forceps to hold the guide needle for puncturing, and since the trocar in the embodiment also involves a step of threading the wire 6 from the needle body 1, the operation of holding with the forceps is inconvenient. For this reason, the structure of the needle body 1 is further improved in this embodiment, that is, the first end of the needle body 1 is set as the needle tip portion 101, the second end is set as the connecting portion 102, and the needle bar 2 is connected to the connecting portion 102. The operator can hold the needle bar 2 to operate, and the stability of the trocar in use is improved through the arrangement of the needle bar 2. To further facilitate the puncturing operation, the needle shaft 2 has an arc-shaped section bent toward the needle tip 101.

For the convenience of manufacture, the needle rod 2 and the needle body 1 are manufactured in an integrated molding mode, so that the diameter of the needle rod 2 is close to that of the needle body 1, namely the diameter of the needle rod 2 is small, and the needle rod is inconvenient to hold in a hand in practical use. Therefore, in the implementation, the handheld part 3 is arranged at one end, far away from the connecting part 102, of the needle rod 2, the diameter of the handheld part 3 is far larger than that of the needle rod 2, an operator can hold the handheld part 3 of the trocar for operation, and the convenience of operation is improved. The needle bar 2 and the hand-held part 3 are fixedly connected, and specifically, one end of the needle bar 2 far away from the connecting part 102 is inserted into the end of the hand-held part 3 and fixed.

The handheld part 3 can be arranged in a cylindrical shape, so that the handheld part is more attached to the palm, and the needle body 1 can be selected as a 17G puncture needle.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
