The invention discloses a using method of a breast lesion catgut embedding positioning needle, which comprises the following steps:

theneedle core 3 extends into theouter needle tube 2, so that thecrochet hook 4 is positioned in the inclined needle point and does not exceed the inclined plane of the inclined needle point;

one end of thepositioning wire 6 is pulled out from the inclined needle tip, and thesoft rubber ball 7 is kept in thecrochet needle 4;

under the coordination of an ultrasonic instrument, theouter needle tube 2 is pushed to enable the inclined needle tip to be positioned at the focus;

the pushingscrew rod 5 is rotated to further position the focus of thecrochet hook 4, after the position is positioned, thepositioning wire 6 is pulled to enable thesoft rubber ball 7 to enter the focus of thecrochet hook 4 from the opening, then theouter needle tube 2 is withdrawn, the pushingscrew rod 5 drives thepuncture needle 1, theneedle core 3 and thecrochet hook 4 to withdraw from the focus, thesoft rubber ball 7 is left at the focus of the disease, and the positioning of the focus (or the position of the tumor) is realized.

In the process of mammary gland surgery, the position of thesoft rubber ball 7 is found to be the position of the tumor along thepositioning line 6, so that the positioning is more accurate, in the prior method, the hard ball or the adaptive dye is used for positioning, and because a certain time is left between the operations after the positioning, the hard ball and the dye can easily cause inaccurate positioning in the time, the positioning needle of the invention can send thesoft rubber ball 7 to the position of the tumor, and thesoft rubber ball 7 can accurately position the position of the tumor by matching with the material of thesoft rubber ball 7.

Because the initial positioning is already close to the focus position, the micro distance is adjusted by pushing the screw rod, so that the positioning is more accurate, and the pain to the patient is less in the process due to the short distance. And because the crochet hook is in a cone structure, the round smooth surface of the outer surface of the crochet hook causes less pain to a patient in the rotating advancing process.

The invention selects thesoft rubber ball 7 as the positioning ball, and the material of thesoft rubber ball 7 is silica gel, latex or polyurethane. The diameter and material of the breast implant determine that the breast implant can be fixed at a certain fixed position in the breast tissue for a long time. Thesoft rubber ball 7 is a solid elastic ball body, the solid elastic ball body can be prevented from being extruded and deformed by mammary tissue, a certain counterforce is formed, and the position of thesoft rubber ball 7 can be kept unchanged under the interaction of the counterforce and the counterforce. The rubber ball and the positioning line are made of X-ray-proof materials and can be detected through X-rays.

The existing positioning balls are all made of hard materials, and as described in the background art, the existing positioning balls are generally metal balls, which are beneficial to delivering to a target position, but the existing positioning balls cannot stably exist at a fixed position due to the influence of the hard materials and the stress condition of mammary tissue; according to the invention, the opening is formed in the delivered needle tube, thesoft rubber ball 7 can be slightly dragged by the positioning line and can extend out of the opening to enter a specified position, the existing hard balls are delivered to a fixed position, and the delivery can not be carried out through the opening of the crochet hook by using the method disclosed by the invention, so that the position of the positioning ball is more accurate and precise.

Thesoft rubber ball 7 selected by the invention is safe and harmless to human body, the process of feeding thesoft rubber ball 7 into human tissue through the needle tube is a common human tissue puncture method, the soft rubber ball can be carried out through the process of surgical operation and is harmless to human body, the diameter of thesoft rubber ball 7 can meet the requirement, the soft rubber ball can not affect mammary tissue, and thesoft rubber ball 7 can be taken out in the process of carrying out mammary operation and only stays in the mammary tissue for a short time, so that the soft rubber ball can not adversely affect the mammary tissue.

As shown in FIG. 1, theouter needle tube 2 is a hollow tube body, one end of which is connected to the tail of thepuncture needle 1, and is internally provided with an internal thread, and thepuncture needle 1 is inserted into the body to feed thecrochet needle 4 portion of thecore needle 3 into the vicinity of the tissue portion in the body. Scales are marked on the outer side of the outer needle tube, and the depth of a focus can be accurately read through the scales, so that an operator can know the position of the focus more.

Theouter needle tube 2 is made of a rigid tube body. Can be stainless steel material,outer needle pipe 2 has certain intensity, and inside sets up the internal thread, can pass through threaded connection withpromotion screw rod 5, through the wrong income of screw thread with screw out, realizes reciprocating ofnook closing member 3.

Thepuncture needle 1 is made of a rigid tube, generally stainless steel, or a nickel-titanium alloy tube. Has a structure of an inclined needle point, which is beneficial to penetrating into the human body.

As shown in fig. 2, the structure of theneedle core 3 is a hollow tubular structure, the head part is acrochet needle 4, and the sharp end of thecrochet needle 4 has the function of penetrating into tissues.

Theneedle core 3 enters from the tail end of theouter needle tube 2 and extends into thepuncture needle 1, and theneedle core 3 and thepuncture needle 1 are coaxially arranged. Thepush screw rod 5 is contacted with theouter needle tube 2 and is in threaded connection, so that the positions of theneedle core 3 and thepuncture needle 1 are fixed.

Thecrochet hook 4 is positioned inside the inclined needlepoint part and does not exceed the inclined plane of the inclined needlepoint, and the vertex of thecrochet hook 4 can be parallel to the inclined plane. Because thebearded needle 4 has a smaller diameter than the oblique needle tip, the lesion tissue can be positioned better.

The inclined needle point is of a cylindrical tubular structure, thecrochet hook 4 is located inside the inclined needle point, when the inclined needle point enters a human body, thecrochet hook 4 is brought into the human body by the inclined needle point, at the moment, the inclined needle point is not moved, and thecrochet hook 4 is driven by the pushingscrew rod 5 to carry out accurate position positioning.

The fine distance adjustment can be realized by the threaded matching of the pushingscrew rod 5 and theouter needle tube 2.

The shape of thecrochet hook 4 is such that the tip may be more advantageous for moving in the tissue. And the space inside can be used for enclosing thesoft rubber ball 7.

The function of thecrochet hook 4 is similar to pitching, thecrochet hook 4 bringing thesoft rubber ball 7 to a more precise position.

The lateral wall ofcrochet hook 4 sets up the opening, and the one end oflocation line 6 is located the opening outside, and the other end oflocation line 6 is located the opening inboard, and when the in-process that crochethook 4 upwards or moved down,soft rubber ball 7 can not move out from the opening voluntarily owing to being blocked by the opening, after the position location ofcrochet hook 4 is accurate, dragslocation line 6 with the hand, extractssoft rubber ball 7, leavessoft rubber ball 7 in the location department.

In some embodiments, thecrochet hook 4 is in a triangular cone structure, and thesoft rubber ball 7 is clamped by the top of the triangular cone and is not easy to float out of the opening in the process of moving up or down.

The width of the opening is slightly smaller than the diameter of thesoft rubber ball 7, and since thesoft rubber ball 7 has a certain elasticity, the soft rubber ball can be pulled out when thepositioning wire 6 is pulled.

Thesoft rubber ball 7 selected by the invention is made of silica gel, latex or polyurethane. The material is softer, is favorable for fixing in the mammary tissue, is easy to keep in a fixed position under the extrusion action of the tissue, and is easy to shift under the extrusion and pushing action of the mammary tissue if the material is harder, so that the positioning is inaccurate.

Because theouter needle tube 2 is in threaded connection with the pushingscrew rod 5, when the outer needle tube is pulled or the screw rod is pushed, the outer needle tube and the pushing screw rod can be pulled out of a body at the same time, and thesoft rubber ball 7 is positioned on the outer side of the crochet needle and is left in the body.

In order to avoid that thepositioning thread 6 located inside the crochet hook is pulled by the crochet hook to influence the position of thesoft rubber ball 7, thepositioning thread 6 is not located inside the crochet hook but outside thecrochet hook 4. When thesoft rubber ball 7 is pulled out from thecrochet hook 4, the position of thesoft rubber ball 7 is not influenced after thecrochet hook 4 is withdrawn from the body.

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