Description

Technical Field

[0001] The utility model relates to the technical field of medical care products, in particular to a simple buried guide needle. Background Art

[0002] In plastic surgery, for example, when performing plastic surgery on patients for aging lower eyelids, buried guide needles are often used to pull medical sutures to suspend and fix the subcutaneous fat of the patient's lower eyelids or the autologous fat tissue filled in to achieve eye bag removal and other operations. In this way, the surgical incision is omitted, and the medical sutures used can be buried under the skin of the patient's lower eyelids for traceless suture fixation. The buried guide needles used are mostly sickle-shaped, with suture threading holes in the middle. For their use, please refer to the relevant content of "68 cases of double eyelid surgery with buried guide needles by Feng Chunfu, Qu Ningrong, Li Peifu, and Zhou Xingliang" in the fourth issue of Volume 4 of the Chinese Journal of Medical Cosmetology in December 1998.

[0003] Regarding the buried guide needle used above, the inventor of this patent found during use that it still has certain defects and shortcomings in use.

[0004] Specifically, on the one hand, only the suture thread holes are opened in the middle, which is only suitable for lower eyelid aging surgery with a slightly larger suture fixation distance. For plastic surgery with a smaller suture fixation distance, such as when the bridge of the nose needs to be raised by transplanting flaps, the corresponding buried guide needle is not very suitable. This is because when the bridge of the nose is raised by implanting flaps after making incisions at the nasal grooves on both sides of the nose, the distance for suturing and fixing the transplanted flap at the bridge of the nose needs to be very small. On the other hand, the suture thread holes opened on it are located at very small locations and are easily broken if not handled with care. Once broken in the patient's skin, it is difficult to remove it and requires the use of a B-ultrasound machine through development technology to find it and slowly pull it out. It is very troublesome to remove it, resulting in poor reliability.

[0005] In this regard, the inventor of this patent combined clinical experience, thought about the problems encountered in clinical work, read a large amount of scientific research materials and literature, and conducted searches and novelties to gradually conceive and design this application to solve related technical problems.

[0013] According to an embodiment of the present invention, both end surfaces of the second flat clamping portion are perpendicular or approximately perpendicular to the axial direction of the second threading hole.

[0014] According to an embodiment of the present invention, the diameter of the first threading hole and the diameter of the second threading hole are both D, and D=0.20mm-0.40mm.

[0015] According to an embodiment of the utility model, the radius of the arc-shaped needle body is R, and R=15.0mm-20.0mm.

[0016] According to one embodiment of the utility model, a straight line L is drawn through the center O of the arc-shaped needle body to the tip of the second spike portion, and a perpendicular line P is drawn from the tip of the first spike portion to intersect with the straight line L to form an intersection A, and the distance between the intersection A and the tip of the second spike portion is H, and H=27.00mm-30.0mm.

[0043] The simple buried guide needle 1000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] Reference Figures 1 to 3 As shown, the simple buried guide needle 1000 provided according to the embodiment of the utility model includes a needle body 10, the outer shape of the needle body 10 is formed into an arc shape, a first threading hole 101 is opened in the middle of the outer wall of the arc-shaped needle body 10, and a second threading hole 102 is opened on the outer wall of the arc-shaped needle body 10 near its first end.

[0045] Based on the above, it can be clearly seen that the present application is mainly used as a simple buried guide needle 1000 during its specific implementation.

[0046] Specifically, when applying the present application, the principle of use of the conventional buried guide needle described in the background art is roughly the same.

[0047] For example, the control Figure 4As shown, when a patient needs to undergo lower eyelid aging surgery, a relatively long medical suture is inserted into the corresponding first threading hole 101 opened in the middle of the outer wall of the needle body 10, and multiple points a, b, c, d, e and f with relatively large spacing are marked from left to right on the skin surface of the patient's lower eyelid. The needle is first inserted at a suitable angle from point a on the skin surface of the patient's lower eyelid, so that the first end of the needle body 10 punctures the skin of the patient's lower eyelid and exits from point b on the skin surface of the patient's lower eyelid. At this time, the two ends of the medical suture thread are still retained outside the patient's lower eyelid skin surface point a. When the second end of the needle body 10 reaches the subcutaneous point b on the patient's lower eyelid skin surface, it is not pulled out, but the needle body 10 is rotated at a proper angle so that the second end of the needle body 10 punctures the skin of the patient's lower eyelid and comes out from the patient's lower eyelid skin surface point c. At this time, the two ends of the medical suture thread are still retained outside the patient's lower eyelid skin surface point a. The first end of the needle body 10 reaches When the needle is under the skin of point c on the patient's lower eyelid skin surface, the needle body 10 is not pulled out, but the needle body 10 is rotated at a suitable angle again so that the first end of the needle body 10 is protruded from point d on the patient's lower eyelid skin surface. This operation is repeated until the first end and the second end of the needle body 10 are both protruded from point f on the patient's lower eyelid skin surface. At this time, the part of the medical suture exposed at point a on the patient's lower eyelid skin surface can be knotted, and the part of the medical suture exposed at point f on the patient's lower eyelid skin surface can be knotted, and the thread ends can be cut off, leaving a length of 1.0 mm for cutting, and then the skin around point a and point f on the patient's lower eyelid is gently lifted to bury the thread knot under the skin. In this way, the patient's lower eyelid aging surgery is completed to achieve the suspension and fixation of the patient's lower eyelid subcutaneous fat or the filled autologous fat tissue to achieve operations such as removing eye bags. The related operations can save the need to open a surgical incision, and the medical suture used can be buried under the patient's lower eyelid skin for traceless suture fixation. During the operation, the needle body 10 does not need to completely penetrate the skin, and the operation is convenient, fast, and safe. It causes little damage to the patient's skin tissue, and the postoperative swelling is light and the recovery is fast. It avoids the steps of skin incision, bandaging, and suture removal, and the patient is easy to accept.

[0048] Similarly, comparison Figure 5As shown, when a patient needs to undergo a nose bridge heightening surgery, a longer medical suture is inserted into the corresponding second threading hole 102 opened on the outer wall of the needle body 10 near the first end thereof, and multiple points a, b, c, d, e and f with smaller spacing are marked in sequence from left to right on the skin surface of the patient's nose bridge, and the needle is first inserted at a suitable angle from point a on the skin surface of the patient's nose bridge, so that the first end of the needle body 10 punctures intradermally at the patient's nose bridge and comes out from point b on the skin surface of the patient's nose bridge. At this time, the two ends of the medical suture are still retained outside point a on the skin surface of the patient's nose bridge. When the second end of the needle body 10 reaches subcutaneously at point b on the skin surface of the patient's nose bridge, it is not pulled out, but the needle body 10 is rotated at a suitable angle so that the second end of the needle body 10 punctures intradermally at the patient's nose bridge and comes out from point c on the skin surface of the patient's nose bridge. At this time, the two ends of the medical suture are still retained outside point a on the skin surface of the patient's nose bridge. When it reaches the subcutaneous part of the skin surface of the patient's nose bridge at point c, the needle body 10 is not pulled out, but the needle body 10 is rotated at a proper angle again so that the first end of the needle body 10 comes out of the needle from the point d on the skin surface of the patient's nose bridge. This operation is repeated until the first end and the second end of the needle body 10 both come out of the needle from the point f on the skin surface of the patient's nose bridge. At this time, the part of the medical suture exposed at the point a on the skin surface of the patient's nose bridge can be knotted, and the part of the medical suture exposed at the point f on the skin surface of the patient's nose bridge can be knotted, and the thread ends can be cut to retain a length of 1.0 mm for cutting, and then the skin around the point a and the point f on the patient's nose bridge can be gently lifted to bury the thread knot under the skin. In this way, the patient's nose bridge heightening surgery is completed, so as to realize the suspension and fixation of the patient's nose bridge subcutaneous fat or the filled autologous fat tissue to realize the operation of nose bridge heightening, etc., and the related operations can save the need to open a surgical incision, and the medical suture used can be buried under the skin of the patient's nose bridge for traceless suture fixation. During the operation, the needle body 10 does not need to completely penetrate the skin, and the operation is convenient, fast, and safe. It also causes little damage to the patient's skin tissue, and the postoperative swelling is light and the recovery is also fast. It also avoids the steps of skin incision, bandaging, and suture removal, and the patient is also easy to accept.

[0049] The use of the above-mentioned application will obviously have the following technical effects:

[0050] Since the needle body 10 is formed in an arc shape, it is convenient to pass back and forth in the patient's skin, so that the operation is smooth. In addition, since a first threading hole 101 is opened in the middle of the outer wall of the arc-shaped needle body 10, and a second threading hole 102 is opened near the first end of the outer wall of the arc-shaped needle body 10, when the patient needs to undergo lower eyelid aging surgery, a medical suture can be passed through the first threading hole 101 to use the present invention. When the patient needs to undergo nose bridge heightening surgery, a medical suture can be passed through the second threading hole 102. The present application is used by threading a medical suture thread through the thread hole 102. At this time, since the second threading hole 102 is arranged on the outer wall of the arc-shaped needle body 10 and is close to its first end, the first end of the needle body 10 can make the passing gap small when passing through the skin of the patient's nose bridge, so that it is indeed suitable for operational requirements. Furthermore, by opening the first threading hole 101 and the second threading hole 102 at different positions, the present application has a wide range of applications, strong applicability and flexibility, and can be used according to actual usage requirements.

[0051] Therefore, through the above-mentioned optimized design, the whole structure of the present application is highly practical and has good use effect.

[0052] Furthermore, in the specific implementation, Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the first end of the needle body 10 is cut to form a first spike portion 103 , and the second end of the needle body 10 is cut to form a second spike portion 104 .

[0053] Therefore, by forming the first sharp thorn portion 103 and the second sharp thorn portion 104 , the needle body 10 of the present application can be facilitated to quickly puncture the patient's skin or the transplanted skin flap.

[0054] On this basis, in the specific implementation, according to one embodiment of the utility model, the middle part of the outer wall of the needle body 10 is die-cast to form a first flat clamping portion 105 whose width is slightly larger than the outer diameter of the needle body 10 , and the first threading hole 101 is located in the middle part of the first flat clamping portion 105 .

[0055] Therefore, when the medical staff holds the needle holder and clamps the first flat clamping part 105, since the first flat clamping part 105 is flat, it is not easy to rotate when clamped, which facilitates the stable operation of the present application, so that the needle body 10 described in the present application is not easy to rotate when penetrating into the patient's skin, making the present application stable and reliable to use.

[0056] Furthermore, since the widest width of the first flat clamping portion 105 is slightly larger than the outer diameter of the needle body 10, the structure of the portion where the first flat clamping portion 105 is located is stable and not easily broken, thereby extending the service life of the present application.

[0057] Furthermore, in a specific implementation, according to an embodiment of the present invention, both end surfaces of the first flat clamping portion 105 are perpendicular or approximately perpendicular to the axial direction of the first threading hole 101 .

[0058] In this way, it is convenient for medical personnel to manipulate the needle body 10 at a suitable angle and orientation, so as to stably clamp the first flat clamping portion 105 on the needle body 10 to facilitate the needle body 10 to be inserted into the patient's skin.

[0059] Furthermore, in the present technical solution, according to one embodiment of the utility model, the outer wall of the needle body 10 is die-cast near its first end to form a second flat clamping portion 106 whose width is slightly larger than the outer diameter of the needle body 10 , and the second threading hole 102 is located in the middle of the second flat clamping portion 106 .

[0060] Therefore, when the medical staff holds the needle holder and clamps the second flat clamping part 106, since the second flat clamping part 106 is flat, it is not easy to rotate when clamped, and it is also convenient to operate the present application stably, so that the needle body 10 described in the present application is still not easy to rotate when it is penetrated into the patient's skin, so that the present application still has good stability and reliability in use.

[0061] Furthermore, since the widest width of the second flat clamping portion 106 is slightly larger than the outer diameter of the needle body 10, the structure of the portion where the second flat clamping portion 106 is located is stable and not easily broken, so that the present application still has a long service life.

[0062] On this basis, in a specific implementation, according to an embodiment of the present invention, both end surfaces of the second flat clamping portion 106 are perpendicular or approximately perpendicular to the axial direction of the second threading hole 102 .

[0063] In this way, it is convenient for medical personnel to manipulate the needle body 10 at a suitable angle and orientation, so as to stably clamp the second flat clamping portion 106 on the needle body 10 to facilitate the needle body 10 to be inserted into the patient's skin.

[0064] In addition, in the specific implementation, Figure 3 As shown, according to an embodiment of the present invention, the diameter of the first threading hole 101 and the diameter of the second threading hole 102 are both D, and D=0.20mm-0.40mm.

[0065] Preferably, in the present technical solution, the aperture D of the first threading hole 101 and the aperture D of the second threading hole 102 can be set to three specifications of 0.20 mm, 0.30 mm and 0.40 mm according to actual use requirements.

[0066] Furthermore, in the specific implementation, continue to compare Figure 3 As shown, according to one embodiment of the present utility model, the radius of the arc-shaped needle body 10 is R, and R=15.0mm-20.0mm.

[0067] Preferably, in the present technical solution, the radius R of the arc-shaped needle body 10 can be set to three specifications of 15.0 mm, 17.0 mm and 20.0 mm according to actual use requirements.

[0068] It should be added that in the specific implementation, Figure 3 As shown, according to one embodiment of the utility model, a straight line L is drawn through the center O of the arc-shaped needle body 10 to the tip of the second spike portion 104, and a perpendicular line P is drawn from the tip of the first spike portion 103 to intersect with the straight line L to form an intersection A, and the distance between the intersection A and the tip of the second spike portion 104 is H, and H = 27.00mm-30.0mm.

[0069] Through continuous debugging and testing, as the optimal clinical design, when the present application is implemented, the aperture of the first threading hole 101 and the aperture D of the second threading hole 102 are both set to 0.30 mm, the radius R of the arc-shaped needle body 10 is set to 17.0 mm, and the H is set to 28.89 mm. In this way, the present application can be more convenient to use and can be adapted to most patients.

[0070] It is further necessary to add that, in a specific implementation, according to the simple buried guide needle 1000 provided in the embodiment of the utility model, the outer diameter of the needle body 10 is set to about 1.0 mm, so that the thickness thereof is neither too large nor too small.

[0071] Other embodiments and the like are not described here by way of example.

[0072] In summary, the simple buried guide needle 1000 provided by the present application, in specific implementation, because the outer shape of the needle body 10 is formed into an arc shape, it is convenient for it to be inserted back and forth in the patient's skin, so that the operation is smooth, and because the middle part of the outer wall of the arc-shaped needle body 10 is provided with a first threading hole 101, and the outer wall of the arc-shaped needle body 10 is provided with a second threading hole 102 near its first end, when the patient needs to undergo lower eyelid aging surgery, the medical suture can be inserted into the first threading hole 101 to use the present application, and when the patient needs to undergo nose bridge surgery, During height-increasing surgery, the present application can be used by threading a medical suture in the second threading hole 102. At this time, since the second threading hole 102 is arranged on the arc-shaped outer wall of the needle body 10 and is close to its first end, the first end of the needle body 10 can make the penetration gap small when passing through the skin of the patient's nose bridge, so that it is truly suitable for operational requirements. Furthermore, by opening the first threading hole 101 and the second threading hole 102 at different positions, the present application has a wide range of applications, strong applicability and flexibility, and can be used according to actual usage requirements.

[0073] Furthermore, when the medical staff holds the needle holder and clamps the first flat clamping part 105, since the first flat clamping part 105 is flat, it is not easy to rotate when clamped, which facilitates the stable operation of the present application, so that the needle body 10 of the present application is not easy to rotate when it is inserted into the patient's skin, making the present application stable and reliable in use. Since the widest width of the first flat clamping part 105 is slightly larger than the outer diameter of the needle body 10, the structure of the part where it is located is stable and not easy to be broken, so that the present application has a long service life.

[0074] Similarly, when the medical staff holds the needle holder and clamps the second flat clamping part 106, since the second flat clamping part 106 is flat, it is not easy to rotate when clamped, and it is also convenient to operate the present application stably, so that the needle body 10 of the present application is still not easy to rotate when it is inserted into the patient's skin, so that the present application is still stable and reliable in use. Since the widest width of the second flat clamping part 106 is also slightly larger than the outer diameter of the needle body 10, the structure of the part where it is located is stable and not easy to be broken, so that the present application still has a long service life.
