Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to a support device for jejunostomy. Background Technology

[0002] Jejunoileostomy is a surgical procedure used to directly connect the jejunum and ileum, typically to bypass diseased segments of the intestine or to restore the continuity of the digestive tract. It is primarily indicated for conditions such as intestinal obstruction, Crohn's disease, intestinal ischemia, or necrosis.

[0003] Surgical techniques for jejunostomy include end-to-end anastomosis, where the two ends are directly anastomosed, conforming to the anatomical structure, but ensuring that the diameters of the two ends are similar. End-to-side anastomosis is also included, where one end is anastomosed to the side wall of another intestinal segment, used when there is a significant difference in diameter. Lateral-to-lateral anastomosis is further included, where the side walls of the two intestinal segments are anastomosed to create a larger anastomosis, reducing the risk of stenosis.

[0004] Currently, some surgical procedures use staplers for anastomosis. However, sometimes the anastomosis angle is too tricky, so medical personnel need to manually suture with needles and sutures. When suturing manually, medical personnel usually rely on experience to determine the needle placement, which can lead to significant deviations between needles. Furthermore, due to the lack of support and clamping devices during the suturing process, medical personnel need to constantly adjust the position of the intestinal segment to ensure the accuracy of the suturing. This undoubtedly makes the suturing process more complicated and troublesome. Utility Model Content

[0005] To address the aforementioned problem of the lack of support and clamping devices in manual suturing, which complicates the suturing process, this invention proposes a support device for jejunostomy, comprising a clamping body with two intersecting arms rotatably connected. An arc-shaped clamping element is mounted at the top of each intersecting arm to clamp and support the suture site of the two intestinal segments.

[0006] A further feature of this invention is that the clamping member has a needle-threading groove, one end of which is open and the other end is closed. The needle-threading groove is also arc-shaped and has the same curvature as the clamping member.

[0007] The beneficial effects of this utility model are as follows:

[0008] The two clamping devices provide support and clamping for the sutured sections of the two intestinal segments, making the suture more stable. The suture needle passes through the needle groove, ensuring accurate needle placement. Since the intestinal tissue within the needle groove is clamped on both sides, it will not shift during suturing, thus avoiding the need for medical personnel to repeatedly adjust the position of the intestinal segments during suturing. This further simplifies the suturing process and speeds up the suturing process. Attached Figure Description

[0012] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0013] This utility model proposes a support device for jejunostomy, including a clamping body 1, which is configured as a scissor shape. The clamping body 1 includes two cross arms 11 arranged in a cross configuration, and the two cross arms 11 are rotatably connected by a rotating shaft.

[0014] The lower end of the cross arm 11 is integrated with a finger ring for easy hand operation. The top of the cross arm 11 is welded with a clamping member 2. The two clamping members 2 work together. The clamping member 2 is set as a quarter circle arc. The two clamping members 2 can achieve the clamping effect of the two intestinal segments. That is, the inner arc of the clamping member 2 abuts against the outer surface of the intestinal segment and squeezes inward for a while, and then clamps tightly, so that some tissue of the two intestinal segments is jointly clamped between the two clamping members 2.

[0015] The clamping member 2 is also provided with a needle-threading groove 21, which is coaxially arranged with the clamping member 2. That is, the needle-threading groove 21 is also set to be arc-shaped, and its arc is the same as that of the clamping member 2. The needle-threading groove 21 is closed at one end and open at the other end.

[0016] During suturing, the suture needle is passed through the needle groove 21, so that the needle landing point is always located on the intestinal tissue within the needle groove 21. This allows for accurate determination of the suturing position. Furthermore, due to the clamping and support of the clamping member 2, the intestinal segment will not deviate, further eliminating the need to adjust the position of the intestinal segment and making the suturing process simpler and more convenient.

[0017] It should be noted that since a full cycle of sewing is required, and each clamping operation can only complete a quarter of the sewing work, the position of the clamping body 1 needs to be adjusted after each sewing operation, and the sewing is repeated until a full cycle of sewing is completed. The needle groove 21 is set open at one end, so that the clamping part 2 can be better removed after the sewing is completed and the knot is tied.

[0018] In summary, this invention uses two clamping members 2 to clamp and support the sutured sections of the two intestinal segments, thereby making the sutured sections more stable. Furthermore, the suture needle passes through the needle groove 21, ensuring accurate needle placement. Since the intestinal tissue within the needle groove 21 is clamped on both sides by the clamping members 2, it will not shift during suturing, thus avoiding the need for medical personnel to repeatedly adjust the position of the intestinal segments during suturing. This further simplifies the suturing process and speeds up the suturing process.

In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
