Description

Technical Field

[0001] This utility model belongs to the field of medical devices and is used for suturing the trocar hole after laparoscopic surgery. Background Technology

[0002] Laparoscopic surgery is a newly developed minimally invasive technique and an inevitable trend in the future development of surgery. Many open surgeries of the past have now been replaced by laparoscopic surgery. The general method of laparoscopic surgery is to make three small incisions of about 1 cm in the patient's abdomen, and insert a tube called a "trocar" into each one. All subsequent operations are performed through these three tubes.

[0003] Postoperatively, it is routine to suture the large-diameter trocar orifice to prevent trocar orifice hernia. However, due to the depth of the trocar orifice, especially in patients with thick abdominal walls, suturing the trocar orifice from the bottom is extremely difficult; this remains an unresolved operational challenge in clinical practice. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a cannula hole suturing device, which allows for the selection of different needle channels and adjustment of the puncture angle, making it suitable for patients of different body types.

[0005] The sleeve hole suturing device provided by this utility model includes a sleeve and a needle-threading platform.

[0006] Unlike traditional sleeves, this sleeve has 2-3 pairs of windows on its wall, which are sealed with silicone film.

[0007] The needle-threading platform includes a left platform and a right platform; the left platform and the right platform are detachably clamped at the upper end of the sleeve; and both the left platform and the right platform are provided with a left needle-threading channel and a right needle-threading channel;

[0008] During suturing, the puncture needle is first inserted through the left puncture path and through the window to bring the suture into the abdominal cavity; the puncture needle is then withdrawn along the original path and inserted into the abdominal cavity through the right puncture path, bringing the suture out of the abdominal cavity.

[0009] The specific design involves a threaded groove on the side wall of the sleeve. When the lower end of the sleeve is inserted into the abdominal cavity, the threaded groove is used to contact the abdominal wall, thereby fixing the abdominal wall in the sleeve position.

[0010] The specific solution involves installing a film around the window to seal it, thus keeping the abdominal cavity airtight.

[0011] The specific design includes a shallow needle insertion channel and a deep needle insertion channel on both the left and right platforms.

[0012] Specifically, on the left and right platforms, the areas closer to the sleeve are designated as deep needle insertion channels, while those farther from the sleeve are designated as shallow needle insertion channels.

[0013] The specific design includes shallow and deep windows, with the deep window being closer to the lower end of the sleeve.

[0014] In the specific design, the end of the needle-threading platform that contacts the abdominal wall is the bottom end, and the end opposite the bottom end is the top end; the area of ​​the bottom end of the needle-threading platform is larger than the area of ​​the top end.

[0015] Features of this utility model:

[0016] 1. The sleeve does not need to be removed when suturing the trocar hole. The needle insertion platform is clamped at its upper end to form a triangular fixation structure. The sleeve is always close to the abdominal wall, the puncture needle path is not easy to deviate, and the suturing effect is accurate.

[0017] 2. The shallow and deep needle channels of this practical design can be used for patients of different body types. Ordinary people can choose to insert the needle through the shallow needle channel for suturing; those with thicker abdominal walls can choose to suture through the deep needle channel; ensure that the needle is inserted into the bottom of the abdominal wall.

[0018] 3. The area at the bottom of the needle insertion platform is larger than that at the top, forming a stable support structure on the abdominal wall; this facilitates the insertion and exit of the puncture needle along the needle tract. Attached Figure Description

[0030] As described in the background art: due to the depth of the trocar opening, especially in patients with thick abdominal walls, it is very difficult to suture the trocar opening from the bottom. Figure 1 A-1 is a schematic diagram of suturing a typical patient. Figure 1 A-2 is a schematic diagram of suturing a patient with a thick abdominal wall. When the patient's abdominal wall is thick, the puncture needle 8 will be inserted to the bottom of the abdominal wall and will be significantly deviated horizontally from the trocar orifice, making it difficult to suture the wound tightly.

[0031] See Figure 2 This utility model provides a trocar hole suturing device, including a sleeve 1 and a needle platform 2; the lower end of the sleeve 1 is used to insert into the abdominal cavity through the trocar hole. During suturing, the needle platform 2 is clamped at the upper end of the sleeve 1 to form a triangular fixing structure; and the needle platform 2 has at least one shallow needle channel 32 and one deep needle channel 31. When encountering ordinary patients, the puncture needle 8 is inserted from the shallow needle channel 32; when the patient's abdominal wall is thick, the puncture needle 8 is inserted from the deep needle channel 31; ensuring that the puncture needle penetrates to the bottom of the abdominal wall.

[0032] The suturing process is as follows:

[0033] See Figure 7 and Figure 8 During suturing, the needle platform 2 is first clamped around the sleeve 1, with the bottom of the needle platform 2 resting on the abdominal wall to form a stable trapezoidal platform. The puncture needle 8 is inserted through the needle passage on the left platform 21, and the puncture needle 8, carrying the suture 5, passes through the window of the sleeve 1 and enters the abdominal cavity. The doctor observes the position of the puncture needle 8 and the suture 5 through the laparoscope 7 and uses clamps 6 to hold the suture. The puncture needle 8 is then withdrawn from the abdominal cavity along the same route and inserted into the abdominal cavity through the needle passage on the right platform 22. The doctor observes the position of the puncture needle 8 through the laparoscope 7 and uses clamps 6 to hook the suture 5 onto the hook at the tip of the puncture needle 8, allowing the suture 5 to follow the puncture needle 8 out of the body. Finally, the sleeve 1 is removed from the trocar opening, and the two ends of the suture 5 are tightened and knotted, thus closing the trocar opening from the bottom of the abdominal wall.

[0034] In this embodiment, both the left platform 21 and the right platform 22 are provided with a shallow needle channel 32 and a deep needle channel 31; when encountering a patient with thickened abdominal wall, the puncture needle 8 is inserted from the deep needle channel 31; when encountering an ordinary patient, the puncture needle 8 is inserted from the shallow needle channel 32.

[0035] In this embodiment, the structure of hooking the suture on the puncture needle 8 to insert it into the abdominal cavity and bringing the suture out of the abdominal cavity is existing clinical technology and will not be described in detail here.

[0036] In this embodiment, the needle-threading platform 2 has a deep needle-threading channel 31 that is closer to the sleeve 1 and a shallow needle-threading channel 32 that is farther from the sleeve 1. The lower end of the sleeve 1 is also provided with a shallow window 11 and a deep window 12, wherein the shallow window 11 is closer to the upper end of the sleeve 1 and the deep window 12 is farther from the upper end of the sleeve 1.

[0037] See Figure 3 The sleeve 1 has a threaded groove 13 on its side wall. When the lower end of the sleeve 1 is inserted into the abdominal cavity, the threaded groove 13 is used to contact the abdominal wall, so that the abdominal wall is fixed in the position of the sleeve 1.

[0038] See Figures 4-6 The needle-threading platform 2 includes a left platform 21 and a right platform 22, which can be separated or clamped together; when the left platform 21 and the right platform 22 are clamped together, they form a ring structure and are sleeved on the upper end of the sleeve 1.

[0039] In this embodiment, the end of the needle platform 2 that contacts the abdominal cavity is the bottom end, and the end opposite to the bottom end is the top end; the area of ​​the bottom end of the needle platform 2 is larger than the area of ​​the top end; the needle platform 2 rests on the abdominal wall to form a stable support structure; which is conducive to the puncture needle entering and exiting along the needle tract.

[0040] The above are embodiments of this utility model. All other designs based on the concept of this patent are included within the scope of protection of this patent.
