Improved embedded guide needle

Abstract

The utility model discloses an improved embedded guide needle, and relates to the technical field of medical instruments. Comprising a needle body, the needle body is of an arc-shaped structure, needle tips are symmetrically arranged at the two ends of the needle body, a lead hole is formed in the midpoint of the needle body in a penetrating mode, and a warning coating is arranged at the end, close to the needle tips, of the needle body; the problems that a needle body accidentally and completely penetrates out due to misoperation, skin depression or displacement deformity is caused by the fact that dermis is sutured through in-situ needle insertion, or tissue damage of a needle insertion part can be caused by repeated in-situ needle insertion are solved, after the needle insertion direction is changed, the needle continues to penetrate in the direction of a pre-sutured or suspended part, then the needle is completely withdrawn, and a subline is led out; the suture can be completed by completely separating and pulling out the needle body and knotting and fixing the suture line, so that the suture process can be more accurate, the situation that the suture effect is affected and a patient is hurt due to the fact that the needle body completely penetrates out is avoided, potential damage to tissue can be reduced, operation is faster, and operation time can be shortened.

Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially, relates to a kind of improved buried guide needle. BACKGROUND

[0002] Buried guide needle is widely used in plastic surgery operation, its feature is that both ends of needle body are needle tip, and the skin is guided and sutured by buried guide needle, which can achieve good surgical results, especially in the part where skin incision is not allowed, the suture and fixation of deep tissue and other tissues can be realized, and the no-dead-space suture of deep wound surface can be completed, so as to achieve the purpose of beauty or correction of deformity.

[0003] However, the traditional buried guide needle has some shortcomings, for example, after the first needle insertion, the needle is slowly withdrawn, improper operation can cause the needle to be completely withdrawn unexpectedly, and the rear needle tip is not retained under the skin, the needle insertion in situ can cause the skin to be depressed or displaced due to suture to the dermis, or repeated needle insertion in situ can cause tissue damage at the needle insertion site.

[0004] Therefore, the utility model provides an improved buried guide needle to solve the above problems. UTILITY MODEL CONTENT

[0005] The utility model aims at providing an improved buried guide needle, which solves the above-mentioned technical problems.

[0006] To achieve the above object, the utility model provides the following technical scheme: an improved buried guide needle, comprising a needle body, the needle body is in circular arc structure, two ends of the needle body are symmetrically provided with needle tip, a lead hole is formed through the midpoint of the needle body, and a warning coating is formed on one end of the needle body close to the needle tip.

[0007] Preferably, the warning coating is symmetrically arranged around the lead hole.

[0008] Preferably, the needle tip includes but is not limited to a circular shape, a triangular shape, and a two-blade shape.

[0009] Preferably, the needle body is made of stainless steel material.

[0010] Preferably, a limiting piece is fixedly sleeved on one end of the needle body close to the needle tip, the maximum width of the limiting piece is the same as the diameter of the needle body, and the limiting piece is in overall elliptical structure.

[0011] Compared with the related art, the improved buried guide needle provided by the utility model has the following beneficial effects:

[0012] The utility model provides a kind of improved buried guide needle, using needle body is sutured to the incision of patient, after passing through lead hole, the needle tip of one end of needle body is inserted into the direction of pre-suture or suspension site from incision or skin fixed point, then the needle tip of other end is retained in the subcutaneous of needle exit site, the warning coating located in the vicinity of needle tip plays a good prompting effect to medical staff in the process, when medical staff finds that warning coating is exposed to the part of skin, stop continuing to exit needle, avoid that needle body is accidentally completely penetrated due to improper operation, in situ insertion may be sutured to dermis and cause skin depression or displacement deformity, or repeated in situ insertion can cause tissue damage in insertion site etc. Problem occurs, after changing insertion direction, continue to run in the direction of pre-suture or suspension site and then completely exit needle, lead secondary line, completely separate needle body and pull out, suture knot fixation can be completed suture, to make suture process can be more accurate, avoid the situation that needle body is completely penetrated and influence suture effect and cause harm to patient, it is beneficial to reduce potential damage to tissue, more fast operation, help to shorten operation time.

[0015] In the drawing: 1, needle body, 2, lead hole, 3, warning coating, 4, limit piece. DETAILED DESCRIPTION

[0016] Example one

[0017] Please refer to Figure 1 The utility model provides a kind of technical scheme, including needle body 1, needle body 1 is round arc structure, the both ends of needle body 1 are symmetrically provided with needle tip, the midpoint of needle body 1 is provided with lead hole 2, and the end of needle body 1 close to needle tip is provided with warning coating 3;Warning coating 3 is symmetric structure with lead hole 2 as center;

[0018] The needle body 1 is used for suturing a patient incision, after the suture thread is passed through the lead hole 2, the needle tip of one end of the needle body 1 is inserted into the skin at the incision or a fixed point and is passed out of the skin at the pre-suturing or suspension position in the direction of the pre-suturing or suspension position, then the needle tip of the other end is retained in the skin at the position where the needle is passed out, in the process, the warning coating 3 located near the needle tip provides a good prompt to the medical staff, when the medical staff find that the warning coating 3 is exposed to the skin, the needle is stopped from being continuously passed out, so that the needle body 1 is not completely passed out due to improper operation, the needle is inserted into the skin at the original position and the skin is sutured, so that the skin is concave or displaced, or the tissue at the position where the needle is inserted is damaged due to repeated insertion of the needle, the direction of the needle is changed, the needle is completely passed out in the direction of the pre-suturing or suspension position, the secondary thread is led out, the needle body 1 is completely pulled out, the suture thread is knotted and fixed, and then the suturing is completed, so that the suturing process is more accurate, the needle body 1 is not completely passed out, the suturing effect is not affected, and the patient is not hurt, potential damage to the tissue is reduced, the operation is faster, and the operation time is shortened.

[0019] The needle tip includes but is not limited to a circular shape, a triangular shape and a double-blade shape;

[0020] Different shapes of the needle tip can adapt to the suturing requirements of different tissues, and the needle tip is more convenient to use.

[0021] The needle body 1 is made of stainless steel material;

[0022] The needle body 1 can have sufficient strength and toughness, so that the needle body 1 is not broken during the suturing process.

[0023] Embodiment two

[0024] Please refer to Figure 2 On the basis of the embodiment one, the utility model provides a technical scheme: the needle body 1 is fixed with the limiting piece 4 at one end close to the needle tip, the maximum width of the limiting piece 4 is same with the diameter of the needle body 1, and the limiting piece 4 is in the whole oval structure.

[0025] Through the design of the oval limiting piece 4, when the medical staff uses the needle body 1 to suture and pass the needle, the needle body 1 can be prevented from being completely passed out, and the needle body 1 can be completely passed out after the suturing is completed, and the smooth surface of the limiting piece 4 and the maximum width less than the diameter of the needle body 1 can further reduce the situation that the needle body 1 is completely passed out, and the tissue at the puncture position is not damaged.
