Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically, particularly to an integrated surgical suture specifically for cervix. Background Art
[0002] Currently in the field of gynecology, wound suturing during cervical lesion surgery is performed with the support of a vaginal speculum. Due to the narrow vaginal space, cervical suturing requires a high level of practical experience from the doctor. Whether it is a U-shaped suture or an eight-shaped suture, it is difficult to expose the position of the needle insertion and removal in a narrow space. In addition, the traditional semi-arc needle holding position is within the arc. After holding the needle, the needle holder will further block part of the field of vision. If the needle is not removed properly, it may cause damage to the vaginal wall, or the needle tip may pierce into adjacent organs such as the bladder and rectum during the operation. In addition, due to factors such as the narrow space and the obstruction of the vaginal speculum, it is difficult for the surgeon to perform the knotting operation.
[0003] In the existing one-piece sutures, the size of the needle and the thickness of the suture are also fixed. For example, the 1-0 type suture has a larger needle and the suture is correspondingly thicker, while the 3-0 type suture has a smaller needle and the suture is correspondingly thinner. The cervical tissue is mainly muscular and has greater toughness. Therefore, in the suture of the cervical wound, if the 1-0 type suture is used, the needle is larger and it is difficult to insert and remove the needle in the narrow space of the vagina. If the 3-0 type suture is used, although the needle is smaller, it is convenient to adjust the direction and enter and exit in a small space, but the suture is too thin, and it is easy to break due to insufficient tension when suturing the muscular tissue of the cervix. Therefore, the existing one-piece suture is difficult to meet the requirements of cervical surgery. At present, there is no one-piece surgical suture specifically for cervical surgery.
[0004] How to solve the above problems has become a technical problem that needs to be solved urgently. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a special integrated surgical suture for cervix which can safely, reliably and quickly complete the suturing and knotting of cervical wound surface so as to effectively shorten the operation time.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A one-piece surgical suture specially designed for the cervix comprises a needle tip and a needle body connected to the needle tip; the needle body is in a concave arc shape, and a needle holder which is smoothly connected to the needle body and is in an upward convex arc shape is provided on the end of the needle body away from the needle tip to stagger the suturing angle and expand the field of vision for facilitating suturing operations in a narrow space; an absorbable suture for suturing cervical wounds is provided on the end of the needle holder away from the needle body.
[0008] Preferably, the absorbable suture comprises an absorbable suture body integrally connected to one end of the needle holder away from the needle body, and a knot-free tail is provided on one end of the absorbable suture body away from the needle holder.
[0009] Preferably, the absorbable suture body is an absorbable suture body with a diameter of 0.35 mm and a length of 25 cm and a predetermined tension.
[0010] Preferably, the knot-free thread tail is an octagon-shaped knot-free thread tail made of absorbable polyester material.
[0011] Preferably, the end of the needle tip away from the needle body is in the shape of a triangular prism to facilitate passing through the tough cervical muscle tissue when suturing the cervical wound, and the end of the needle tip connected to the needle body is in the shape of a cylinder to effectively reduce the suturing resistance during the process of suturing the cervical wound.
[0012] Due to the adoption of the above structure, the utility model has the following beneficial effects:
[0013] When the utility model is used, during a gynecological cervical surgery, after the surgeon uses a vaginal speculum to open the front and back walls of the patient's vagina to expose the cervical surgery site, during the process of suturing the cervical wound, the surgeon clamps the needle holding body with a long needle holding forceps, operates the needle holding body in a corresponding suturing manner, drives the needle body together with the needle tip and the absorbable suture to complete the suturing and knotting of the patient's cervical wound along a predetermined surgical path. When suturing a cervical wound, the arc-shaped design in which the needle holder and the needle body are staggered at different angles can be used to stagger the suturing angle during suturing, thereby expanding the surgeon's field of vision to facilitate observation of the needle insertion and removal positions, facilitating suturing operations in a narrow space, and effectively shortening the operation time. In addition, the use of thicker absorbable sutures with knot-free tails for suturing operations not only eliminates the need for deep knotting after suturing, but only requires knotting and fixing once, and the thicker absorbable sutures can provide better compression tension for the cervical muscle tissue to prevent the knot from breaking, further reducing the operation time, and can safely, reliably and quickly complete the suturing and knotting of the cervical wound, further shortening the operation time to reduce the occurrence of intraoperative complications and improving the safety of cervical surgery. Therefore, the utility model has the advantage of being able to safely, reliably and quickly complete the suturing and knotting of the cervical wound to effectively shorten the operation time.

[0019] like Figure 1As shown, the utility model provides an integrated surgical suture specifically for cervix, comprising a needle tip 1 and a needle body 2 connected to the needle tip 1; the needle body 2 is in a concave arc shape, and a needle holding body 3 which is smoothly connected to the needle body 2 and is in an upward convex arc shape is provided on the end of the needle body 2 away from the needle tip 1 to stagger the suturing angle and expand the field of vision for facilitating suturing operation in a small space; an absorbable suture 4 for suturing cervical wounds is provided on the end of the needle holding body 3 away from the needle body 2. During use, in gynecological cervical surgery, the surgeon uses a vaginal speculum to open the patient's anterior and posterior vaginal walls to expose the cervical surgical site. During the suturing of the cervical wound, the surgeon clamps the needle holder 3 with a long needle head forceps, and operates the needle holder 3 in a corresponding suturing manner to drive the needle body 2 together with the needle tip 1 and the absorbable suture 4 to work along a predetermined surgical path. The needle tip 1 punctures and penetrates the patient's cervical muscle tissue to drive the needle body 2 and the needle holder 3 to guide the absorbable suture 4 through the patient's cervical muscle tissue to achieve the suturing of the cervical wound, thereby completing the suturing and knotting of the patient's cervical wound. When suturing the cervical wound, the needle holder 3 and the needle body 2 are used to form a suture between each other. The staggered arc design can stagger the suture needle angle during suturing, expand the surgeon's field of view to facilitate observation of the needle tip 1's insertion and exit positions, and is beneficial for suturing in a narrow space to shorten the operation time. In addition, a thicker absorbable suture 4 with a knot-free tail is used for suturing operations. Not only does it not require deep knotting after suturing, but only requires one knot to be fixed. Moreover, the thicker absorbable suture 4 can provide better compression tension for the cervical muscle tissue to prevent the knot from breaking, which can further reduce the operation time and improve safety. Therefore, the suturing and knotting of the cervical wound can be completed quickly and safely, reliably, and the operation time can be shortened to reduce the occurrence of intraoperative complications and improve the safety of cervical surgery.
[0020] In this embodiment, the absorbable suture 4 includes an absorbable suture body 41 integrally connected to the end of the needle holder 3 away from the needle body 2, and a knot-free tail 42 is provided on the end of the absorbable suture body 41 away from the needle holder 3. The absorbable suture body 41 is an absorbable suture body with a diameter of 0.35 mm and a length of 25 cm with a predetermined tension. The knot-free tail 42 is an octagonal knot-free tail made of absorbable polyester material. During use, the needle holder 3 is clamped by a long needle holding forceps, and the needle holder 3 is operated in a corresponding suturing method to drive the needle body 2 together with the needle tip 1 and the absorbable suture body 41 and the knot-free tail 42 of the absorbable suture 4 to work along a predetermined surgical path, and the needle tip 1 punctures through the patient's cervical muscle tissue to drive the needle body 2 and the needle holder 3 to guide the absorbable suture body 41 and the knot-free tail 42 to pass through the patient's cervical muscle tissue to achieve the cervical wound suturing operation, thereby completing the suturing and knotting of the patient's cervical wound, and another In addition, when a thicker absorbable suture body 41 with a knot-free tail 42 is used for suturing operations, the knot-free tail 42 not only eliminates the need for deep knotting after suturing, but only requires one knot to fix the suture. In addition, the thicker absorbable suture body 41 can provide better compression tension for the cervical muscle tissue, preventing the knot from breaking, further reducing the operation time and improving safety. Therefore, the suturing and knotting of the cervical wound surface can be completed quickly and safely, reliably, and the operation time can be shortened to reduce the occurrence of intraoperative complications, thereby improving the safety of cervical surgery.
[0021] In this embodiment, the end of the needle tip 1 away from the needle body 2 is in a triangular prism shape to facilitate passing through the tough cervical muscle tissue when suturing the cervical wound, and the end of the needle tip 1 connected to the needle body 2 is in a cylindrical shape to effectively reduce the suturing resistance during the process of suturing the cervical wound.
[0022] When this embodiment is used specifically, first, in a gynecological cervical surgery, the surgeon uses a vaginal speculum to open the patient's anterior and posterior vaginal walls to expose the cervical surgical site; secondly, in the process of suturing the cervical wound, the long-needle holding forceps are used to clamp the needle holding body 3, and the needle holding body 3 is operated in a corresponding suturing manner to drive the needle body 2 together with the needle tip 1 and the absorbable suture 4 to work along a predetermined surgical path, and the needle tip 1 pierces the patient's cervical muscle tissue to drive the needle body 2 and the needle holding body 3 to guide the absorbable suture 4 to pass through the patient's cervical muscle tissue to achieve the cervical wound suturing operation, thereby completing the suturing and knotting of the patient's cervical wound; then, when suturing the cervical wound, the needle holding body 3 and the needle body 2 are staggered at an angle to each other. The arc-shaped design can stagger the suture needle angle during suturing, expand the surgeon's field of view to facilitate observation of the needle insertion and exit positions of the needle tip 1, and is beneficial for suturing in a narrow space to shorten the operation time; finally, when using a thicker absorbable suture body 41 with a knot-free tail 42 for suturing, the knot-free tail 42 not only eliminates the need for deep knotting after suturing, but only requires knotting and fixing once, and the thicker absorbable suture body 41 can provide better compression tension for the cervical muscle tissue to prevent the knot from breaking, which can further reduce the operation time and improve safety. Therefore, the suturing and knotting of the cervical wound surface can be completed safely, reliably and quickly, shortening the operation time to reduce the occurrence of intraoperative complications and improving the safety of cervical surgery.
[0023] In conclusion, the utility model adopts the above structure and has the advantage of being able to safely, reliably and quickly complete the suturing and knotting of the cervical wound surface to effectively shorten the operation time.
