This invention relates to an embedding guide that facilitates precise positioning and suturing, belonging to the field of medical devices. Each of the two arms has one end fixedly connected to a handle, and the other end of each arm has a needle hole penetrating through it. The other end of each arm also has a pointed tip. The advantages of this invention are: the two arms of the embedding guide can extend from a small incision to a deep location far from the incision, and are positioned on the skin surface by the two pointed tips to indicate the location for subsequent operations. The needle can then be inserted from the skin surface, with the needle hole used to determine the needle insertion position. As the needle passes through the two needle holes, the suture will sew up and catch the deep tissue. When the embedding guide is subsequently withdrawn from the incision, the suture on the skin surface is guided to the incision site for suturing, facilitating the suspension and lifting of deep tissue through the suture.

Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically to an embedded guide that facilitates positioning and suturing. Background Technology

[0002] In facial rejuvenation surgery, minimizing the incision size while simultaneously using a small incision to suspend and lift deep (sagging) tissues to achieve facial rejuvenation has always been a challenge. This is because the distance from the incision around the ear to the perioral area, malar fat pad, and buccal fat pad is approximately 8-12 cm, making it difficult to operate through a small incision. Current techniques lack specialized surgical instruments for suspending deep tissues through small incisions. Summary of the Invention

[0003] The technical problem to be solved by this invention is how to facilitate the suspension of deep tissues through small incisions.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an embedding guide that is beneficial for positioning and suturing includes a handle and two arms. One end of each of the two arms is fixedly connected to the handle. The other end of each arm has a needle hole that passes through the arm. The other end of each arm has a pointed tip.

[0005] The beneficial effects of this invention are as follows: the two arms of the implantation guide can extend from a small incision to a deep position far from the incision, and are positioned on the skin surface by two tips to indicate the location for subsequent operations. Then, a needle can be inserted from the skin surface, with needle holes used to determine the needle insertion position. As the needle passes through the two needle holes, sutures are used to secure the deep tissue. Subsequently, when the implantation guide is withdrawn from the incision, the sutures on the skin surface are guided to the incision site for suturing, facilitating the suspension and lifting of deep tissues through the sutures.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the tip has side blades on both sides.

[0008] The beneficial effect of adopting the above-mentioned further approach is that when the arm is inserted into the face through the incision, the sharp side blade at the tip can help the arm dissect the subcutaneous tissue, thereby smoothly extending to the position where suspension is required.

[0009] Furthermore, it also includes a screw and a first limiting nut, one end of which is fixedly connected to the middle of one of the support arms, and the other end passes through the middle of the other support arm and is threadedly connected to the first limiting nut.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the maximum angle of the two arms opening can be limited by adjusting the position of the first limiting nut on the screw, which facilitates the sewing operation.

[0011] Furthermore, it also includes a second limiting nut, which is threaded to the middle of the screw and located between the two support arms.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, by adjusting the position of the second limiting nut on the screw, when the support arm extends into the subcutaneous tissue from the incision, the first limiting nut and the second limiting screw are located on both sides of the other support arm, but do not clamp the support arm, thus limiting the range of motion of the support arm. Through the opening and closing action of the two support arms, the tips and side blades of the two support arms cut and peel the subcutaneous tissue. During needle insertion, the first limiting nut and the second limiting nut clamp the other support arm from both sides, which can fix the relative position of the two support arms, and the position of the two needle holes remains unchanged, increasing the accuracy of needle insertion.

[0013] Furthermore, the needle hole is a strip-shaped hole.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the needle hole is a strip-shaped hole, which has a slightly larger area than a round hole, making it easier to find the needle-threading position when threading the needle.

[0015] Furthermore, the length of the strip hole is 2cm-2.5cm.

[0016] The advantage of adopting the above-mentioned further solution is that the length of the strip hole is as large as possible to increase the error tolerance during needle movement.

[0017] Furthermore, the length of the support arm is 15-25cm.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the length of the arm is suitable for the distance from the preauricular incision to the corner of the mouth for most people, and meets the needs of deep tissue suspension operations in most cases.

[0019] Furthermore, the length of the handle is 10-12cm.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the length of the handle can meet the needs of fixed hand grip.

[0021] Furthermore, each of the two supporting arms has a clamping tooth on one side facing each other, and the clamping tooth is located at the other end of the corresponding supporting arm.

[0022] The beneficial effect of adopting the above-mentioned further solution is that it helps the arm clamp and pull up the deep tissue, so that the deep tissue is between the two needle holes, making it easier to pass through (suspend) the deep tissue when inserting the needle from the body surface.

[0023] Furthermore, the handle is cylindrical, the outer wall of the handle has a grid-like anti-slip grid, and the side wall of the handle near the support arm has a grip positioning part.

[0024] The beneficial effects of adopting the above-mentioned further solution are: the operator can firmly hold the handle with one hand and complete the needle insertion operation with the other hand, so that one person can complete the needle insertion operation, reducing personnel costs.

[0025] Furthermore, the two opposing sides of the two support arms have anti-slip textures.

[0026] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip texture reduces slippage during operation. Attached Figure Description

[0035] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0036] like Figures 1-6 As shown, this embodiment provides an embedding guide that facilitates positioning and suturing, including a handle 1 and two support arms 2. One end of each of the two support arms 2 is fixedly connected to the handle 1, and the other end of each support arm 2 has a needle hole 3 that passes through the support arm 2, and the other end of each support arm 2 has a tip 4.

[0037] Taking a deep facial tissue suspension procedure via a small incision as an example, the two arms 2 of the implanted guide can extend from a small incision around the ear to a deep position on the face. The two tips 4 are inserted into or exit the skin, thus positioning themselves on the skin surface to indicate the location for subsequent procedures. A needle can then be inserted from the skin surface, with a needle insertion hole 3 used to determine the needle insertion position. The needle sequentially passes through the skin, one of the needle insertion holes 3, the tissue within the skin (deep tissue), the other needle insertion hole 3, and the skin on the other side. Thus, while passing through both needle insertion holes 3, sutures are used to secure the deep tissue. When the implanted guide is subsequently withdrawn from the incision, the sutures on the skin surface are guided to the incision site for suturing. The sutures pull the deep tissue towards the incision, thereby suspending and lifting the deep tissue through the sutures.

[0038] The needle hole 3 can be circular, strip-shaped, or other geometric shapes.

[0039] Wherein, the support arm 2 can be as follows: Figure 1 As shown, the straight rod shape can be replaced by a bent rod shape with the other end curved.

[0040] Specifically, when the two arms 2 come close to each other (close), the other end of the two arms 2 can be used to clamp deep tissues.

[0041] The buried guide device of this embodiment, which facilitates positioning and suturing, is not only suitable for deep tissue suspension of the face, but can also be applied to deep tissue suspension procedures in other locations. Deep tissue refers to subcutaneous tissue far from the incision site.

[0042] Based on any of the above schemes, the tip 4 has side blades on both sides.

[0043] When the arm 2 is inserted into the face through the incision, the sharp side blade of the tip 4 can help the arm 2 dissect the subcutaneous tissue, so that it can be smoothly extended to the position where suspension is required.

[0044] Specifically, such as Figure 2 As shown, tip 4 needs to be sharpened, and sharp side edges need to be ground on both sides of tip 4. The two side edges and tip 4 form a shape as shown. Figure 2 The pointed angle of the triangle shown.

[0045] Based on any of the above schemes, it also includes a screw 5 and a first limiting nut 6. One end of the screw 5 is fixedly connected to the middle of one of the support arms 2, and the other end passes through the middle of the other support arm 2 and is threadedly connected to the first limiting nut 6.

[0046] The maximum angle at which the two arms 2 open can be limited by adjusting the position of the first limiting nut 6 on the screw 5, which facilitates sewing operations.

[0047] Specifically, the other support arm 2 can move relative to the screw 5, meaning that the screw 5 does not affect the opening and closing action of the two support arms 2.

[0048] Based on any of the above schemes, a second limiting nut 7 is also included. The second limiting nut 7 is threadedly connected to the middle part of the screw 5 and is located between the two support arms 2.

[0049] When the support arm 2 extends into the subcutaneous tissue through the incision, by adjusting the positions of the first limiting nut 6 and the second limiting nut 7 on the screw 5, the first limiting nut 6 and the second limiting nut 7 are located on both sides of the other support arm 2, but without clamping the support arm 2, thus limiting the relative range of motion of the two support arms 2. Through the opening and closing action of the two support arms 2, the tips and side blades of the two support arms 2 shear and dissect the subcutaneous tissue. Figure 3 As shown, when the two support arms 2 reach the predetermined position or clamp the deep tissue, the position of the second limiting nut 7 on the screw 5 is adjusted so that it abuts against the inside of the other support arm 2, and the position of the first limiting nut 6 on the screw 5 is adjusted so that it abuts against the outside of the other support arm 2. The first limiting nut 6 and the second limiting nut 7 clamp the other support arm 2 from both sides, thereby fixing the relative position of the two support arms 2, that is, restricting the opening and closing of the two support arms 2. The position of the two needle holes 3 remains unchanged, so as to increase the accuracy of needle movement and simplify the operation.

[0050] Based on any of the above schemes, the needle hole 3 is a strip-shaped hole.

[0051] The needle hole 3 is a strip-shaped hole. Compared to the round hole, the strip-shaped hole has a slightly larger area, making it easier to find the needle insertion position when threading the needle.

[0052] Specifically, such as Figure 2 As shown, the strip-shaped hole is arranged along the length direction of the support arm 2.

[0053] Based on any of the above schemes, the length of the strip hole is 2cm-2.5cm.

[0054] The length of the slot should be as large as possible to increase the margin of error when threading the needle. Furthermore, the width of the slot should also be as large as possible to provide sufficient space for threading the needle.

[0055] Based on any of the above schemes, the length of the support arm 2 is 15-25cm.

[0056] The length of arm 2 is suitable for the distance from the preauricular incision to the corner of the mouth for most people, meeting the needs of deep tissue suspension operations in most cases.

[0057] Based on any of the above schemes, the length of the handle 1 is 10-12cm.

[0058] The beneficial effect of adopting the above-mentioned further solution is that the length of the handle 1 can meet the needs of fixed hand grip.

[0059] Based on any of the above schemes, the two supporting arms 2 have clamping teeth 9 on their opposing sides, and the clamping teeth 9 are located at the other end of the corresponding supporting arm 2.

[0060] Clamping teeth 9 help the support arm 2 clamp and pull up deep tissue, so that the deep tissue is between the two needle holes, making it easier to pass through (suspend) the deep tissue when inserting the needle from the body surface.

[0061] Specifically, each support arm 2 is provided with two rows of clamping teeth 9, each row of clamping teeth 9 is arranged along the length direction of the strip hole, and the two rows of clamping teeth 9 are located on both sides of the width direction of the strip hole.

[0062] Furthermore, the handle 1 is cylindrical, the outer wall of the handle 1 has a grid-like anti-slip grid, and the side wall of the handle 1 near the support arm 2 has a grip positioning part.

[0063] Specifically, the gripping and positioning part is an arc-shaped depression. When inserting the needle, the operator can firmly hold the handle 1 with one hand, place the thumb in the arc-shaped depression, and complete the needle insertion operation with the other hand. One person can complete the needle insertion operation, reducing personnel costs.

[0064] Furthermore, the two opposing sides of the two support arms 2 have anti-slip textures 8.

[0065] When the support arm 2 is inserted into the subcutaneous tissue through the incision, it is necessary to operate the opening and closing of the two support arms 2 to dissect the subcutaneous tissue. The anti-slip texture 8 can reduce slippage during operation.

[0066] In one specific embodiment, taking the deep facial tissue suspension operation through a small incision as an example: the two arms 2 of the buried guide can be inserted from the small incision around the ear. At the same time, the sharp side blades on both sides of the tip 4 can help the arms 2 to smoothly dissect the subcutaneous tissue, so that the needle hole 3 can reach the deep tissue position.

[0067] Two pointed tips 4 are inserted into or protrude from the skin to locate the area on the skin surface, indicating the position for subsequent procedures.

[0068] like Figure 4 As shown, the ellipse between the two arms 2 represents deep tissue, and the thick solid line passing through the two needle holes 3 represents the suture. The needle is inserted from the skin surface, and the needle holes 3 are used to determine the needle insertion position. The needle sequentially passes through the skin, one of the needle holes 3, the tissue within the skin (deep tissue), the other needle hole 3, and the skin on the other side. Thus, while passing through the two needle holes 3, the suture catches on the deep tissue. Specifically, the deep tissue refers to the deep tissue of the face.

[0069] like Figure 5 As shown in the diagram, the dashed ellipse between the two supports 2 represents the original position of the deep tissue, the solid ellipse between the two supports 2 represents the suspended deep tissue, and the thick solid line passing through the two needle holes 3 represents the suture. When the buried guide is withdrawn from the incision, the suture on the skin surface is guided to the incision for suturing. The suture pulls the deep tissue towards the incision, thereby suspending and lifting the deep tissue through the suture.
