Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a uterine incision auxiliary suturing device. Background Art

[0002] Modern people have irregular lifestyles and eating habits, and their body resistance is poor. The incidence of tumors is increasing, and the trend of tumor onset at a younger age is also strengthening. Uterine fibroids are a common gynecological disease. They are benign tumors formed by the proliferation of uterine smooth muscle tissue. Once discovered during a physical examination and assessed as requiring surgery, the tumor needs to be completely removed. After the tumor is removed, an incision is usually left on the uterus. In order to speed up healing and recovery, the incision needs to be sutured after the tumor is removed. The suturing of the uterine incision has its own particularity. To avoid infection, the skin section of the uterine incision needs to be folded over to the inside of the uterus for suturing.

[0003] The existing suturing method is to insert a long-handled surgical forceps holding a suture needle into the human abdominal cavity from the abdominal surgical incision site, use the long-handled instrument to clamp the suture needle, and perform the needle threading operation inside the human abdominal cavity and outside the uterus. Since the skin section of the uterine incision must be folded over to the inside of the uterus for suturing, the suturing operation is difficult, requires high standards from the doctor, and takes a long time.

[0004] Therefore, how to reduce the difficulty and improve the efficiency when suturing the uterine incision is a technical problem that has not yet been solved by existing technologies. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned technology and provide a uterine incision auxiliary suturing device to solve the technical problems of low suturing efficiency and great difficulty in operation of uterine incision suturing in the prior art.

[0006] To this end, the present invention provides a uterine incision auxiliary suturing device, comprising: an auxiliary expansion member, the auxiliary expansion member comprising a first sleeve with openings at both ends and at least three expansion pieces provided at one end of the first sleeve, the expansion pieces having an inward-retracted state and an outward-retracted state; when the expansion pieces are in the inward-retracted state, they can enter the human body through a surgical sleeve; the expansion pieces are integrally formed on one end of the first sleeve; an auxiliary ring, the outer wall of the auxiliary ring can be detachably connected to the expansion piece, and the inner wall of the auxiliary ring is used to connect to the uterus; a sterile sleeve, the sterile sleeve comprising a plastic sleeve with openings at both ends, and a first elastic ring and a second elastic ring respectively provided at both ends of the plastic sleeve; the plastic sleeve is made of transparent plastic material;

[0007] Under the action of external force, the sterile sleeve can pass through the auxiliary expansion piece and enter the uterus through the auxiliary ring, and the opening after the first elastic ring and the second elastic ring are naturally opened is larger than the natural opening of the uterus. Both the first elastic ring and the second elastic ring can pass through the natural opening of the uterus under the action of external force.

[0008] Preferably, the expansion piece is a metal spring sheet, which is fixedly connected to one end of the first sleeve. In the natural state, the expansion piece is in an outward expansion state; when an external force is applied, the expansion piece can overcome its own elastic force and bend inward to an inward expansion state.

[0009] Preferably, there are 3-5 expansion pieces.

[0010] Preferably, the expansion piece includes a connecting portion and a hook portion, one end of the connecting portion is fixedly connected to one end of the first sleeve, and the other end of the connecting portion is fixedly connected to the hook portion; the outer wall of the auxiliary ring can enter the interior of the hook portion and be squeezed and fixedly connected with the hook portions on at least 3 expansion pieces.

[0011] Preferably, the inner wall of the auxiliary ring is coated with bio-glue, and the outer side of the bio-glue is covered with easy-to-tear release paper.

[0012] Preferably, the uterine incision auxiliary suturing device also includes long-handled forceps, which can be extended from the first sleeve into the human body to clamp the auxiliary ring between the expansion pieces, or stick the outer wall of the human uterine incision to be sutured to the inner wall of the auxiliary ring.

[0013] Preferably, the uterine incision auxiliary suturing device further comprises a stapler for cooperating in suturing the uterine incision and removing the portion of uterine tissue to which the auxiliary ring is adhered.

[0014] The uterine incision auxiliary suturing device of the present invention establishes a sterile passage between the uterus and the outside of the human body through the vagina by using an auxiliary expansion piece, an auxiliary ring and a sterile sleeve. It passes through the vagina but isolates the bacteria in the vagina, so that they cannot cause infection to the uterine incision; then the uterine incision is pulled into the sterile passage through the natural opening of the uterus by the auxiliary ring, or inside the sterile passage, or pulled out of the human body through the sterile passage, and then sutured. At this time, the uterine incision has been turned outward, and suturing is simple and quick, which reduces the suturing difficulty and shortens the suturing time; after suturing is completed, the uterus can be restored.

[0023] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] This embodiment provides a uterine incision auxiliary suturing device, see Figures 1 to 3 As shown, it includes: an auxiliary expansion piece 1, an auxiliary ring 2 and a sterile sleeve 3.

[0025] Among them, the auxiliary expansion member 1 includes a first sleeve 11 with openings at both ends and at least three expansion pieces 12 arranged at one end of the first sleeve 11. The expansion pieces 12 have an inward-retracted state and an outward-supported state; when the expansion pieces 12 are in the inward-retracted state, they can enter the human body through the surgical sleeve.

[0026] The outer wall of the auxiliary ring 2 can be detachably connected to the expansion piece 12 (elastic extrusion connection in this embodiment), and the inner wall of the auxiliary ring 2 is used to be connected to the uterus.

[0027] The sterile sleeve 3 comprises a plastic sleeve 31 with two ends opened, and a first elastic ring 32 and a second elastic ring 33 respectively provided at two ends of the plastic sleeve 31; the plastic sleeve 31 is made of transparent plastic material.

[0028] Under the action of external force, the sterile sleeve 3 can pass through the auxiliary expansion piece 1 and enter the uterus through the auxiliary ring 2, and the opening after the first elastic ring 32 and the second elastic ring 33 are naturally opened is larger than the natural opening of the uterus. The first elastic ring 32 and the second elastic ring 33 can both pass through the natural opening of the uterus under the action of external force.

[0029] In the uterine incision auxiliary suturing device of this embodiment, the expansion piece 12 is a metal spring fixedly connected to one end of the first sleeve 11. In the natural state, the expansion piece 12 is in an outward expansion state; under the action of external force, the expansion piece 12 can overcome its own elastic force and bend inward to a retracted state.

[0030] Before entering the surgical cannula, the elastic expansion piece 12 needs to be squeezed inward by external force (such as human hands) to make it collapse inward, and then it can enter the surgical cannula. After entering the surgical cannula, it is pushed inward by the first cannula 11 until the expansion piece 12 passes through the surgical cannula and naturally bounces open, opposite to the surgical incision of the uterus.

[0031] In the uterine incision auxiliary suturing device of this embodiment, there are 3-5 expansion pieces 12. The expansion pieces 12 are evenly spaced along the opening of the first sleeve 11. In this embodiment, the number of the expansion pieces 12 is 4.

[0032] See Figure 2 In the uterine incision auxiliary suturing device of this embodiment, the expansion piece 12 includes a connecting portion 121 and a hook portion 122. One end of the connecting portion 121 is fixedly connected to one end of the first sleeve 11, and the other end of the connecting portion 121 is fixedly connected to the hook portion 122. The outer wall of the auxiliary ring 2 can enter the interior of the hook portion 122 and be squeezed and fixedly connected with the hook portions 122 on at least three expansion pieces 12. The hook portions 122 have an arcuate surface. The concave arcuate surface can clamp the upper and lower ends of the auxiliary ring 2, allowing the auxiliary ring 2 to be more securely mounted on the hook portion 122.

[0033] The inner wall of the auxiliary ring 2 is coated with bio-glue, and the outer surface of the bio-glue is covered with easy-to-tear release paper. When the auxiliary ring 2 is inserted into the human abdomen through the first sleeve 11, the release paper adheres to the inner wall of the auxiliary ring 2. After the auxiliary ring 2 is inserted into the human abdomen and installed inside the hook portions 122 of the multiple expansion pieces 12 using surgical forceps, the release paper is removed using surgical forceps. At this point, the outer wall of the uterine incision can be lifted with surgical forceps and adhered to the inner wall of the auxiliary ring 2. The bio-glue ensures a very strong adhesive connection between the auxiliary ring 2 and the uterine incision, facilitating subsequent operations.

[0034] The uterine incision auxiliary suturing device of this embodiment further includes long-handled forceps that can be extended from the first cannula 11 into the human body to engage the auxiliary ring 2 between the expansion pieces 12, or to adhere the outer wall of the human uterine incision to be sutured to the inner wall of the auxiliary ring 2. The long-handled forceps can not only grasp the auxiliary ring 2 and insert it into the human body through the first cannula 11, but also engage the outer wall of the auxiliary ring 2 between the multiple expansion pieces 12, and also grasp the outer wall of the uterine incision and adhere it to the inner wall of the auxiliary ring 2.

[0035] The uterine incision auxiliary suturing device of this embodiment further includes a stapler for cooperating in suturing the uterine incision and removing the portion of uterine tissue to which the auxiliary ring 2 is adhered.

[0036] Using the uterine incision auxiliary suturing device of this embodiment, the auxiliary ring 2 and the uterine incision connected to the inner wall of the auxiliary ring 2 are pulled out from the natural channel of the uterus to the inside of the sterile sleeve 3, or they can be pulled out of the human body through the sterile sleeve 3, and then the lower part of the auxiliary ring 2 is clamped with a stapler so that the auxiliary ring 2 is located on one side of the stapler and the rest of the uterus is located on the other side of the stapler. At this time, needle and thread are used to sew the part close to the stapler on the side facing the uterus. After suturing is completed, the auxiliary ring 2 and part of the uterine tissue adhered to the auxiliary ring 2 can be cut off from the side of the stapler facing the auxiliary ring 2.

[0037] The method of using the uterine incision auxiliary suturing device in this embodiment is as follows: Figure 3 The simulated uterus 4 shown is used to simulate the human uterus:

[0038] refer to Figure 3As shown, before using the uterine incision auxiliary suturing device of this embodiment, the location of the human abdominal surgical incision should be pre-inserted with a surgical cannula commonly used in minimally invasive surgery (tumor removal is generally performed through this surgical cannula). One end of the first cannula 11 connected to the expansion piece 12 is aligned with the external opening of the surgical cannula. External force is used to retract the expansion piece 12 inward. The retracted expansion piece 12 is then inserted into the surgical cannula, pushing the first cannula 11 inward so that the end connected to the expansion piece 12 passes through the surgical cannula and enters the human abdominal cavity. After passing through the surgical cannula, the expansion piece 12 naturally opens and is positioned opposite the location of the uterine incision.

[0039] Use long-handled tweezers or other tools to clamp the auxiliary ring 2, insert it into the first sleeve 11, and continue to push it through the first sleeve 11 into the human body; the auxiliary ring 2 is a ring-shaped structure. Use long-handled tweezers or other tools to place the auxiliary ring 2 between the multiple expansion pieces 12, so that the outer wall of the expansion piece 12 enters the position of the hook portion 122 of the expansion piece 12. The expansion piece 12 holds the auxiliary ring 2 tightly under the action of its own elastic force;

[0040] Use long-handled tweezers or other tools to tear off the release paper on the inner wall of the auxiliary ring 2, and remove the release paper from the body to expose the bio-glue applied on the inner wall of the auxiliary ring 2;

[0041] Use long-handled tweezers or other tools to pick up the human tissue at the uterine incision site, and fit the outer wall of the human tissue at the incision site to the inner wall of the auxiliary ring 2. Do this step by step until the outer wall of the human tissue at the uterine incision site is completely fitted to the inner wall of the auxiliary ring 2.

[0042] Use long-handled tweezers or other tools to hold the second elastic loop 33 of the sterile sheath 3, pass through the first cannula 11, and then enter the human abdomen, and then pass through the auxiliary loop 2 and the uterine incision to enter the uterus, and then further enter the vagina through the natural opening of the uterus; use long-handled tweezers or other tools to hold the first elastic loop 32 of the sterile sheath 3, and then enter the human abdomen, and then pass through the auxiliary loop 2 and the uterine incision to enter the uterus; the openings of the first elastic loop 32 and the second elastic loop 33 after they are naturally opened are larger than the natural opening of the uterus;

[0043] It should be noted that when one side of the second elastic ring 33 is gripped with long-handled tweezers or other tools, the portion can be delivered through the natural opening of the uterus. Without the aid of tools, the second elastic ring 33, like the first elastic ring 32, cannot be delivered through the natural opening of the uterus because the opening after natural opening is larger than the natural opening of the uterus.

[0044] Arrange the sterile sleeve 3 so that the first elastic ring 32 is located inside the uterus and the second elastic ring 33 is pulled out of the human body through the human vagina;

[0045] Then, use long-handled tweezers or other tools to push the auxiliary ring 2 away from the expansion piece 12, and continue to push the auxiliary ring 2 through the first elastic ring 32 into the sterile sleeve 3; depending on the patient's condition, the auxiliary ring 2 can be pushed into the sterile sleeve 3, or the auxiliary ring 2 can be pushed through the sterile sleeve 3, out of the vagina, and to the outside of the human body;

[0046] Then, use the stapler to clamp the lower part of the auxiliary ring 2, so that the auxiliary ring 2 is located on one side of the stapler and the rest of the uterus is located on the other side of the stapler. At this time, use needle and thread to sew the part close to the stapler on the side facing the uterus. After suturing, cut off the auxiliary ring 2 and the part of the uterine tissue adhered to the auxiliary ring 2 from the side of the stapler facing the auxiliary ring 2, and then push the uterus back into place.

[0047] Use long-handled tweezers or other tools to enter the uterus from one end of the second elastic ring 33 through the plastic cover of the sterile cover 3 and the natural opening of the uterus, clamp the first elastic ring 32, pull it out of the uterus, and pull the sterile cover 3 out of the human body.

[0048] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this innovative technical solution.
