Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fascia suturing device. Background Art

[0002] Laparoscopic surgery is an application of laparoscopic surgery in general surgery. It has been applied to various general surgery modalities and is gradually reaching or exceeding the therapeutic effects of open surgery. Laparoscopic surgery uses a trocar to enter the abdominal cavity, resulting in a small incision. Abdominal organs are not touched, and organs are not exposed to air. The surgery minimally disrupts the patient's physiological functions. Postoperative scars are small and aesthetically pleasing, pain is minimal, and recovery is rapid. Patients and their families experience minimal postoperative complications, leading to an increasing number of patients accepting laparoscopic surgery. Simultaneously, an increasing number of surgeons are learning to use laparoscopy, and the technique is becoming increasingly sophisticated.

[0003] An abdominal wall trocar is a passageway for laparoscopic surgical instruments to enter the abdominal cavity from the outside. After the trocar is removed at the end of the procedure, a "well-shaped" defect is created in the abdominal wall. Trocars vary in size, and they can be 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, or even larger. Each trocar leaves a different size defect in the abdominal wall. Closing the puncture hole is challenging, and the smaller the hole, the greater the difficulty. Clinically, myofascial defects are rarely closed with a 5 mm puncture hole, while full-thickness myofascial defects are difficult to close with a 10 or 12 mm puncture hole. Therefore, myofascial defects in the abdominal wall are a common cause of puncture hole incisional hernias after laparoscopic surgery.

[0004] Prior to 2014, numerous reports indicated that the incidence of transthoracic incisional hernias was approximately 0.5-5%. These cases primarily involve incarceration of the jejunum or greater omentum into the myofascial defect, often presenting as acute abdomens. If incarcerated, these cases can lead to serious complications such as intestinal obstruction, intestinal perforation, and omental necrosis, necessitating further surgical intervention. Clinically, factors such as unclosed or incomplete closure of the transthoracic defect, morbid obesity, transthoracic infection, intraoperative enlargement of the transthoracic defect or forced specimen removal, and diabetes are all contributing factors to transthoracic incisional hernias. Trocars of all sizes are associated with the risk of transthoracic incisional hernias. Recent studies have shown that, despite minimal postoperative discomfort at the transthoracic site, the incidence of umbilical transthoracic hernias, as detected by physical examination or ultrasound, is 26% after laparoscopic cholecystectomy and 35% after laparoscopic gastric bypass surgery. Transthoracic incisional hernias are often underestimated or undiagnosed. If a perforation hernia occurs within one month after surgery, suture closure of the myofascial defect at the perforation effectively prevents a perforation incisional hernia. Hernias that occur after one month are called degenerative perforation incisional hernias. Even with the use of a hernia repair mesh, there is still a 29% recurrence rate. Therefore, perforations 8 mm or larger, perforations enlarged during surgery, those with a high body mass index, and perforations with a smaller outer diameter (<5 mm) require suture closure.

[0005] The minimally invasive fascia closure device, with application number 201611024846.4, includes an operating rod, a pair of rotating arms at the lower end of the operating rod that are controlled by a drive mechanism to open or close, and a wire feed needle. The rotating arms are provided with a wire feed channel through which the wire feed needle passes, and a protective mechanism is provided at the outlet of the wire feed channel to prevent the needle from puncturing tissue. This minimally invasive fascia closure device has the following shortcomings:

[0006] 1) The connection between the operating rod and the rotating arm is fixed and cannot be rotated to adjust the angle, making it difficult to suture wounds of different sizes after surgery. The wound suture range is small, the operation is difficult to operate, and the operation time is long;

[0007] 2) The operating lever is an integrated structure, making it difficult to install internal components. Utility Model Content

[0008] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a fascia suturing device with increased wound suturing range, good surgical operability and high efficiency.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A fascia suturing device includes an operating handle, a movable rod and a steering head. The operating handle is provided with a guide channel extending to both ends. The movable rod is movably sleeved in the guide channel. One end of the operating handle is rotatably connected to one end of the operating handle. A connecting channel connected to the guide channel is provided in the steering head. Outlets are respectively provided on both sides of the other end of the steering head. The outlets connect the connecting channel and the external space of the steering head. Two flexible rings are provided at one end of the movable rod extending into the guide channel. The flexible rings are passed through the connecting channel and can be extended from the two outlets respectively. A handle is provided at the other end of the movable rod.

[0011] As a further improvement of the above technical solution:

[0012] The flexible ring is in the shape of an elongated strip.

[0013] The flexible ring is a silicone ring.

[0014] An oblique groove for the thread hooking needle to pass through is provided on the outer side of the operating handle.

[0015] The operating handle is composed of two half-handle bodies, the guide channel is formed between the two half-handle bodies, the steering head is composed of two half-turning heads, and the connecting channel is formed between the two half-turning heads.

[0016] The two half handle bodies are engaged with each other through a tenon and a mortise.

[0017] A half-side column is respectively provided on both sides of the half-handle body, and the half-side columns of the two half-handle bodies are spliced ​​together to form a whole column. The opposite sides of the two half-rotating heads are respectively provided with connecting holes, and the connecting holes are rotatably sleeved on the corresponding whole columns.

[0018] A guide block is sandwiched between the two half-rotating heads, and guide surfaces are respectively provided on both sides of the guide block, and the guide surfaces are connected to the corresponding outlets and the connecting channels.

[0019] An angle limiting structure for limiting the angle between the operating handle and the movable rod is provided between the operating handle and the movable rod.

[0020] The angle limiting structure includes flexible limiting teeth and multiple limiting grooves. Each limiting groove is provided on the operating handle and is spaced apart around the rotation center of the operating handle. The flexible limiting teeth are provided on the movable rod and are clamped in any limiting groove.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] The fascia suturing device of the present invention is used as follows: first, the fascia suturing device is inserted through the puncture hole into the abdominal cavity, then the movable rod is pushed into the guide channel by the handle, so that two flexible rings extend from two outlets respectively; a hook needle (also called a thread feed needle) is inserted to drive the suture to obliquely penetrate the abdominal wall muscle fascia and peritoneum through the puncture hole, and then the hook needle is pulled out through one flexible ring; at the same time, the other end of the suture is inserted into the other flexible ring; then, the movable rod is pulled out of the guide channel by the handle to bring the two flexible rings together into the connecting channel, and the operating handle is pulled out, bringing out the two ends of the suture; then, the two ends of the suture are tightened and knotted to close the fascia defect of the puncture hole. Because the steering head is rotatably connected to the operating handle, the angle can be adjusted relative to the operating handle. Thus, under the guidance of the steering head at different angles, suturing of different sizes of wounds after surgery can be achieved, thereby increasing the range of wound suturing, improving surgical operability, and increasing efficiency.

In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0031] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] Figures 1 to 3An embodiment of the fascia suturing device of the present invention is shown. The fascia suturing device of this embodiment includes an operating handle 1, a movable rod 2 and a steering head 3. The operating handle 1 is provided with a guide channel 4 running through both ends. The movable rod 2 is movably sleeved in the guide channel 4. One end of the operating handle 1 is rotatably connected to one end of the operating handle 1. A connecting channel 5 communicating with the guide channel 4 is provided in the steering head 3. Outlets 6 are respectively provided on both sides of the other end of the steering head 3. The outlets 6 connect the connecting channel 5 with the external space of the steering head 3. Two flexible rings 7 are provided at one end of the movable rod 2 extending into the guide channel 4. The flexible ring 7 is passed through the connecting channel 5 and can be extended from the two outlets 6 respectively. A handle 8 is provided at the other end of the movable rod 2.

[0033] The fascia suturing device is first inserted through the puncture hole into the abdominal cavity. The movable rod 2 is then pushed into the guide channel 4 via the handle 8, causing the two flexible rings 7 to extend from the two outlets 6. The hook needle (also called a thread feed needle) is inserted, driving the suture to obliquely penetrate the abdominal wall muscle fascia and peritoneum through the puncture hole. The hook needle is then pulled out through one flexible ring 7. Simultaneously, the other end of the suture is inserted into the other flexible ring 7. The movable rod 2 is then pulled out of the guide channel 4 via the handle 8, bringing the two flexible rings 7 together into the connecting channel 5. The operating handle 1 is then pulled out, bringing out the two ends of the suture. The two ends of the suture are then tightened and knotted to close the fascia defect in the puncture hole. Since the steering head 3 is rotatably connected to the operating handle 1, the angle can be adjusted relative to the operating handle 1. Thus, under the guidance of the steering head 3 at different angles, different sizes of wounds after surgery can be sutured, which increases the range of wound suture, improves surgical operability, and increases efficiency.

[0034] Furthermore, in this embodiment, the flexible ring 7 is in the shape of an elongated strip, which is convenient for extending from the outlet 6 and retracting into the connecting channel 5. The flexible ring 7 is in the shape of an annular ring, which refers to a structure connected end to end, and does not specifically refer to a circle.

[0035] Furthermore, in this embodiment, the flexible ring 7 is a silicone ring. On the one hand, it is easy to bend and extend from the outlet 6 and retract into the connecting channel 5, and on the other hand, it reduces collision damage to the body.

[0036] Furthermore, in this embodiment, an oblique groove 101 for the thread hooking needle to pass through is provided on the outside of the operating handle 1, so as to facilitate the insertion of the thread hooking needle into the abdominal cavity.

[0037] Furthermore, if Figure 2 As shown, in this embodiment, the operating handle 1 is composed of two half handle bodies 11, with the guide channel 4 formed between the two half handle bodies 11. The steering head 3 is composed of two half rotating heads 31, with the connecting channel 5 formed between the two half rotating heads 31. Compared with the integrated structure, when installing internal components, the internal components can be directly clamped between the two half handle bodies 11, making the installation of internal components easy.

[0038] Furthermore, in this embodiment, the two half handle bodies 11 are engaged with each other through the tenon 12 and the mortise 13, so as to facilitate the assembly of the operating handle 1.

[0039] Furthermore, in this embodiment, a half-side column 14 is provided on each side of the half-handle body 11, and the half-side columns 14 of the two half-handle bodies 11 are spliced ​​together to form a whole column. The opposite sides of the two half-turning heads 31 are respectively provided with connecting holes 311, and the connecting holes 311 are rotatably sleeved on the corresponding whole columns. In this way, the two half-handle bodies 11 are first spliced ​​together to form the operating handle 1, and then the two half-turning heads 31 are respectively rotatably sleeved on the corresponding whole columns through the connecting holes 311, and spliced ​​together to form the steering head 3, which is convenient for overall installation. In other embodiments, in order to improve the stability of the overall structure, the spliced ​​two half-handle bodies 11 and the two half-turning heads 31 can be welded or glued together to fix them.

[0040] Furthermore, in this embodiment, guide blocks 32 are sandwiched between the two half-rotating heads 31. Guide surfaces 321 are provided on either side of the guide blocks 32. The guide surfaces 321 connect the corresponding outlets 6 to the connecting passages 5. Guided by the guide surfaces 321, the flexible ring 7 can be extended from the outlet 6 and retracted into the connecting passage 5 more smoothly.

[0041] Furthermore, in this embodiment, an angle limiting structure 9 is provided between the operating handle 1 and the movable rod 2 to limit the angle between the two. Thus, the angle limiting structure 9 can limit the operating handle 1 and the movable rod 2 to different relative angles, thereby expanding the range of wound suturing and saving surgical time.

[0042] Furthermore, in this embodiment, the angle limiting structure 9 includes a flexible limiting tooth 91 and a plurality of limiting grooves 92. Each limiting groove 92 is provided on the operating handle 1 and is spaced apart around the rotation center of the operating handle 1. The flexible limiting tooth 91 is provided on the movable rod 2 and is locked in any limiting groove 92. The flexible limiting tooth 91 can be a rubber body or an elastic hard body. It can be locked in the limiting groove 92 to limit the angle between the operating handle 1 and the movable rod 2, and can also rotate the movable rod 2 relative to the operating handle 1 under a certain external force to adjust the relative angle. In other words, the angle limiting structure 9 can have an angle limiting effect on the operating handle 1 and the movable rod 2, but it does not limit them rigidly, so that they can also be rotated relative to each other to adjust the angle.

[0043] The oblique groove 101 accurately aligns the incision wound surface and sutures the peritoneum and fascia, facilitating incision closure and achieving optimal fascia contraction, thereby reducing the incidence of puncture hole complications such as hernia and bleeding. Using an inside-out suturing method, the needle notch can be retracted without assistance, reducing incision closure time and difficulty.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the scope of protection of the present invention.
