Abstract
Description
Technical Field
[0001] This utility model relates to a surgical aid, specifically a vaginal speculum used for suturing the soft birth canal after childbirth. Background Technology
[0002] Clinically, existing vaginal speculum devices can only meet the needs of routine gynecological examinations, such as observing vaginal and cervical lesions, assisting in the collection of secretions, and performing biopsies. However, soft tissue tears caused during childbirth can be deep, reaching the upper vagina or even tearing the cervix. These deep tears are difficult to suture due to the insufficient length of existing vaginal speculum devices, making it challenging to fully expose the wound. The small external opening of ordinary vaginal speculum devices also hinders the use of needle holders during suturing. Therefore, ordinary speculum devices are insufficient for suturing soft tissue tears after childbirth. Retractors are often used to suture deep vaginal and cervical wounds, but this provides limited exposure and can easily lead to excessive traction. Furthermore, the use of assistant retractors increases labor costs. Most existing suturing instruments are modifications and upgrades of ordinary vaginal speculum devices used in gynecology, such as adding light sources and auxiliary components, but they still cannot meet the suturing needs of deep soft tissue tears caused by childbirth. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this invention is to provide a vaginal speculum for suturing the soft birth canal after childbirth.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a vaginal speculum for suturing the soft birth canal after childbirth, comprising a left speculum and a right speculum that are symmetrically fixed to the same end of a scissor-shaped support rod. The scissor-shaped support rod has a large rivet through its scissor-shaped part, allowing the left and right parts of the scissor-shaped support rod to rotate around the scissor-shaped part of the large rivet. The right speculum and the left speculum are arc-shaped plate structures with their inner arc surfaces facing each other. The outer ends of the right speculum and the left speculum are provided with spherical blades, and the outer tips of the blades form an arc. The other end of the support rod is provided with a left handle and a right handle, respectively.
[0005] Furthermore, the support rod is rotatably connected to the left and right handles via small rivets, and the plane in which the left and right handles rotate is perpendicular to the plane of movement of the support rod.
[0006] Furthermore, the support rod is provided with a single hole J for the folding shaft at the connection points with the left and right handles, and the central axis of the single hole J for the folding shaft is parallel to the movable surface of the support rod. The connection points with the support rod at the left and right handles are provided with a U-shaped connection structure at the end, and the left and right side walls of the U-shaped connection structure are provided with double holes N for the folding shaft of the handle. The single hole J for the folding shaft of the support rod is located in the U-shaped connection structure. A small rivet passes through the single hole J for the folding shaft of the support rod and the double holes N for the folding shaft of the handle, so that the support rod is rotatably connected to the left and right handles, and the left and right handles rotate around the small rivet.
[0007] Furthermore, the support rod and the left and right handles are respectively provided with stepped limiting surfaces H, and when the limiting surfaces H of the left and right handles are in contact with the limiting surface H of the support rod, the left and right handles and the support rod are on the same plane.
[0008] Furthermore, the support rods connected to the left and right handles are respectively provided with fixed tooth plates that mesh with the limit teeth K.
[0009] Furthermore, elastic steel sheets are respectively provided on the inner arc surfaces of the right and left openers. The elastic steel sheets are bent and one end is fixedly connected to the inner arc surfaces of the right and left openers. The elastic movable opening of the elastic steel sheet faces the blade.
[0010] Furthermore, each side of the elastic steel sheet is provided with a side positioning plate that is perpendicularly connected to the inner arc surface of the right opener and the left opener.
[0011] Furthermore, the elastic steel sheets of the right and left openers respectively hold a lamp source G, with the lamp beads of the lamp source G facing the blade.
[0012] Furthermore, the left opener, right opener, support rod, left handle, right handle, and blade are made of medical-grade stainless steel, and the left opener and right opener are integrally formed with the blade.
[0013] With the above design, this invention can reach deep into the cervix and upper vagina, facilitating the suturing of deep vaginal and cervical lacerations; both the internal and external parts can be fully opened and rotated, effectively exposing the suturing field of view, facilitating the surgeon's observation, and also facilitating the needle holder suturing operation; the external handle is foldable, which can meet the suturing of vaginal walls of different lengths and locations, and the folding of the handle can also avoid touching the surgeon and contaminating the instruments, which is conducive to aseptic operation.
[0014] This invention facilitates the suturing of deep vaginal tears and cervical wounds caused by childbirth. It provides a wide field of vision during use, making it easy to hold the needle forceps for suturing. It solves the problem that existing methods of suturing wounds after childbirth only allow for the use of hands or hooks to expose the field of vision. It can be operated by one person, saving labor costs, suturing wounds in a timely manner, and reducing postpartum blood loss. Attached Figure Description

[0034] like Figure 1-18 As shown, a vaginal speculum for suturing the soft birth canal after childbirth includes a left speculum dilator 1 and a right speculum dilator 2, which are symmetrically fixed to the same end of a scissor-type support rod 3. The scissor-shaped portion of the support rod 3 is pierced by a large rivet 6, which also passes through the spindle hole L of both the right speculum dilator 2 and the left speculum dilator 1. The right speculum dilator 2 and the left speculum dilator 1 can rotate radially along the central axis of the large rivet 6, with a rotation angle range of 0-60°. The right speculum dilator 2 and the left speculum dilator 1 are arc-shaped plate structures with their inner arc surfaces facing each other. Spherical blades 8 are provided at the outer ends of both the right speculum dilator 2 and the left speculum dilator 1. Furthermore, the outer tip of the blade 8 forms an arc, and the left and right sides of the other end of the support rod 3 are respectively provided with a left handle 5 and a right handle 4. The support rod 3 connected to the left handle 5 and the right handle 4 is respectively provided with a fixed tooth plate 12 that meshes with the limiting tooth K. When the right opener 2 and the left opener 1 are opened to a certain angle, the limiting tooth K of the fixed tooth plate 12 is locked. Before the next operation, the right opener 1 and the left opener 2 will always maintain this opening angle. The left opener 1, the right opener 2, the support rod 3, the left handle 5, the right handle 4, and the blade 8 are made of medical stainless steel, and the left opener 1 and the right opener 2 are integrally formed with the blade 8.
[0035] The support rod 3 is rotatably connected to the left handle 5 and right handle 4 via small rivets 7, and the plane in which the left handle 5 and right handle 4 rotate is perpendicular to the movable plane of the support rod 3. Specifically, the connection points between the support rod 3 and the left handle 5 and right handle 4 are each provided with a single hole J for the support rod folding shaft. The central axis of the single hole J for the support rod folding shaft is parallel to the movable surface of the support rod 3. The connection points between the left handle 5 and right handle 4 and the support rod 3 are each provided with a U-shaped connection structure at the end, and the left and right side walls of the U-shaped connection structure are each provided with a double hole N for the handle folding shaft. The support rod 3 is provided with a single hole J for the support rod folding shaft. Located in the U-shaped connection structure, the small rivet 7 passes through the single hole J of the folding shaft of the support rod and the double hole N of the folding shaft of the handle, so that the support rod 3 is rotatably connected to the left handle 5 and the right handle 4, and the left handle 5 and the right handle 4 rotate around the small rivet 7. The rotatable connection parts of the support rod 3 and the left handle 5 and the right handle 4 are respectively provided with stepped limiting surfaces H. When the limiting surfaces H of the left handle 5 and the right handle 4 are in contact with the limiting surfaces H of the support rod 3, the left handle 5 and the right handle 4 are on the same plane as the support rod 3. Due to the structure of the limiting surface H, the left handle 4 and the right handle 5 can only rotate in the N direction, and the rotation angle range is 0-150°.
[0036] The inner arc surfaces of the right opener 2 and the left opener 1 are respectively provided with elastic steel sheets 9. The elastic steel sheets 9 are bent and one end is fixedly connected to the inner arc surfaces of the right opener 2 and the left opener 1. The elastic movable opening of the elastic steel sheet 9 faces the blade 8. A side positioning plate 10 is respectively provided on one side of the elastic steel sheet 9, which is perpendicularly connected to the inner arc surfaces of the right opener 2 and the left opener 1. The elastic steel sheets 9 of the right opener 2 and the left opener 1 respectively hold a lamp source G. The lamp beads of the lamp source G face the blade 8. The lamp source G is a disposable sterile lamp module.
[0037] The working principle of this invention is as follows: During childbirth, if there is a deep vaginal or cervical tear, the surgeon takes the suture device, turns on the light source G, closes the two flaps of the right dilator 2 and the left dilator 1, and inserts them into the vagina. Using the left handle 5 and the right handle 4 to abduct, the two flaps of the dilator open, supporting the vaginal wall and exposing the wound. After achieving a satisfactory angle, the opening angle is fixed by the fixing plate 12, freeing the surgeon's hands. Turning on the light source G earlier provides better illumination of the suture field. If the mother's vaginal wall is short or the tear is not particularly deep, the exposed handles... If the handle is too long, it can be folded using the 7 small rivets to prevent it from interfering with the suturing operation or contaminating the sterile handle due to facial contact. After suturing, loosen the fixing plate 12, close the left handle 5 and the right handle 4 to close the two pages of the right retractor 2 and the left retractor 1, and then withdraw the suture device from the vagina. The entire process can be fixed after the field of vision is exposed, without the need for continuous force, which facilitates subsequent operations by the surgeon. If the vaginal wall is short and the left handle 5 and the right handle 4 are relatively too long, the left handle 5 and the right handle 4 can also be folded to prevent contact with unsterilized areas and effectively avoid postpartum infection.
[0038] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
