AI Technical Summary
The risk of deep anastomosis leakage is high, especially in patients with hypertrophy or pelvic stenosis. The existing suture technology is difficult to effectively expose and operate, resulting in an increased risk of anastomosis tear.
A cyclic deep anastomosis perimeter reinforcement device is adopted, including a 17mm 1/2c stitching needle, a first thread body and a second thread body. The horizontal rotation of the anastomosis port reveals the operation field of the aastomosis port, reduces the operating range of the aastomosis port, and avoids tearing of the anastomosis caused by vertical pulling.
It effectively reduces the amplitude of the needle operation, avoids tearing caused by vertical pulling of the anastomosis, and improves the stability and convenience of the anastomosis.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of circumferential reinforcement of deep anastomotic stomas, and particularly relates to a rotary deep anastomotic stoma circumferential reinforcement device. Background Art
[0002] Anastomotic leakage is a serious complication after digestive tract reconstruction. Especially in recent years, with the widespread development of neoadjuvant therapy, its adverse effects on anastomotic healing have become an increasingly difficult challenge for surgeons to face.
[0003] For deep anastomotic stomas, such as low anterior resection of the rectum (the anastomotic stoma is 5 cm from the anal verge), the risk of anastomotic leakage is higher. Therefore, most doctors will choose to perform a protective ileostomy, but in fact, it cannot promote anastomotic healing and reduce the occurrence of leakage. Even more, after the protective stoma is reversed, late anastomotic leakage (more than half a year) still occurs from time to time. This may be related to the formation of abscesses and ulcers caused by micro-leakage of the anastomotic stoma, which can seriously lead to septicemia and endanger life. Therefore, it is worthy of attention to study anastomotic techniques that can prevent micro-leakage of the anastomotic stoma.
[0004] Research shows that it is still very difficult to achieve completely no leakage in the anastomotic stoma after instrument anastomosis. Additional reinforcement of the anastomotic stoma to prevent micro-leakage is a coping strategy. In fact, many doctors at home and abroad have successively reported anastomotic stoma reinforcement techniques, including interrupted suture, continuous suture, etc.
[0005] However, since the anastomotic stoma of low anterior resection is located deep in the pelvis, in patients with large body size and preoperative radiotherapy, the pelvis is often narrow, resulting in difficult exposure of the operating field near the anastomotic stoma and very difficult suture. Using the continuous suture with the EB403 barbed suture of Johnson & Johnson is a technique worthy of promotion, but the posterior wall suture is often very difficult, mainly because it requires very high exposure skills for the assistant and cannot use too much force to tear the anastomotic stoma.
[0006] After many attempts at posterior wall suture, a technique - rotary circumferential continuous reinforcement suture - was developed. The core point is to use a modified suture. By pulling the two ends of the suture and horizontally rotating the anastomotic stoma, the needle insertion site is fully exposed within the operating field of the sewing needle. This not only reduces the amplitude of the sewing needle operation but also avoids tearing of the anastomotic stoma caused by vertical pulling. Summary of the Invention
[0007] The present invention aims to provide a rotary deep anastomotic stoma circumferential reinforcement device to solve the problems raised in the above background art.
[0008] To achieve the above object, the present invention provides the following technical solutions:
[0009] A rotary deep anastomotic stoma circumferential reinforcement device, the reinforcement device includes a sewing needle, a first thread body, a locking ring, and a second thread body;
[0010] The suture needle is a 17mm 1 / 2c type suture needle, and its tail end is butt - jointed with the first wire body. The tail end of the first wire body is butt - jointed with a locking ring, and the other end of the locking ring is connected to the second wire body.
[0011] Preferably, the first wire body is a barbed wire with a length of 20 cm.
[0012] Preferably, the second wire body is a non - barbed wire with a length of 10 cm.
[0013] Furthermore, a suture needle can also be butt - jointed at the end of the second wire body far from the locking ring; the second wire body is a barbed wire with a length of 20 cm.
[0014] Preferably, the first wire body and the second wire body are in colors different from human body tissues.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] By adopting the improved suture, the present invention makes the anastomotic stoma rotate horizontally by pulling the sutures at both ends, so that the needle - inserting part is fully exposed in the operation field of the suture needle. This not only reduces the amplitude of suture needle operation, but also avoids the anastomotic stoma from being torn due to vertical pulling. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further describes the present invention in detail with reference to the drawings and embodiments:
[0022] As Figure 1 shown, a rotary deep anastomotic stoma circumferential reinforcement device, the reinforcement device includes a suture needle 1, a first wire body 2, a locking ring 3 and a second wire body 4;
[0023] The suture needle 1 is a 17mm 1 / 2c type suture needle 1, and its tail end is butt - jointed with the first wire body 2. The tail end of the first wire body 2 is butt - jointed with the locking ring 3, and the other end of the locking ring 3 is connected to the second wire body 4.
[0024] The first wire body 2 is a barbed wire with a length of 20 cm.
[0025] The second suture 4 is a barbless suture with a length of 10 cm.
[0026] Furthermore, a sewing needle 1 can be docked at one end of the second suture 4 far from the locking ring 3; the second suture 4 is a barbed suture with a length of 20 cm.
[0027] The first suture 2 and the second suture 4 are in colors different from human flesh tissues, which further facilitates the suture work for medical staff.
[0028] The specific implementation process is as follows:
[0029] Example 1: Using a single - needle suture
[0030] 1. The laparoscopic needle holder first passes through the locking ring and then "vertically" clamps the sewing needle so that the locking ring does not need to be searched for in subsequent operations.
[0031] 2. The first stitch is very important. Start suturing as far as possible from the 6 - 9 o'clock position (at least 3 o'clock). Insert the needle from the tissue on the distal side of the anastomosis and exit from the proximal side, ensuring vertical suturing, with a marginal distance of 3 - 5 mm and a stitch distance of 3 - 5 mm. Suture as much tissue as possible and apply appropriate force when tightening the suture.
[0032] 3. Starting from the second stitch, when inserting the needle, the left - hand forceps clamp the suture at an appropriate position and pull the suture to expose the anastomosis within the best operating field of the sewing needle, and suture counter - clockwise stitch by stitch. The assistant only needs to pick open the overlying tissue above to expose part of the anastomosis.
[0033] 4. Continuously suture as far as possible to 9 o'clock, then the barbed suture self - locks once and turns to suture the posterior wall.
[0034] 5. Suturing the posterior wall is a difficult point: Place the intestinal tube on the left side of the pelvic cavity to expose the right side of the anastomosis (basically in the same position as the first stitch). The assistant uses the right - hand forceps to push aside the proximal intestinal tube, and the left - hand forceps clamp the extension line of the locking ring and pull it counter - clockwise; the surgeon uses the left - hand forceps to clamp the barbed suture at an appropriate position and also pull it counter - clockwise. The effect is that the posterior - wall anastomosis (for example, within the range of 4 - 9 o'clock) rotates to the 3 - 6 o'clock position, facilitating needle insertion and suturing.
[0035] 6. Finally, converge at the locking - ring position, tie a knot between the barbed suture and the extension line to end the suture.
[0036] Example 2: When using a double - needle suture
[0037] 1. The laparoscopic needle holder first passes through the locking ring and then "vertically" clamps the sewing needle so that the locking ring does not need to be searched for in subsequent operations.
[0038] 2. The first stitch is crucial. Start suturing as close as possible to the 6 - 9 o'clock position (at least 3 o'clock). Insert the needle from the tissue distal to the anastomosis and exit from the proximal side, ensuring vertical suturing. The marginal distance should be 3 - 5 mm and the stitch distance should be 3 - 5 mm. Suture as much tissue as possible and apply appropriate force when tightening the suture thread.
[0039] 3. From the second stitch onwards, when inserting the needle, hold the suture thread at an appropriate position with the left - hand forceps and tug on the suture thread to expose the anastomosis within the optimal operating field of the needle. Suture counter - clockwise stitch by stitch. The assistant only needs to lift the overlying tissue to expose part of the anastomosis.
[0040] 4. Suture continuously as close as possible to 9 o'clock and then turn to suture the posterior wall.
[0041] 5. Place the intestine on the left side of the pelvic cavity to expose the right side of the anastomosis (basically in the same position as the first stitch). The assistant uses the right - hand forceps to push aside the proximal intestine and holds the barbed suture sewn to 9 o'clock with the left - hand forceps, pulling it counter - clockwise, and can deviate slightly towards the cephalad direction; the surgeon holds the other end of the barbed suture at an appropriate position and also pulls it counter - clockwise in the plane of the anastomosis. The effect is to flatten the posterior - wall anastomosis (for example, within the range of 4 - 9 o'clock) and rotate it to the 3 - 6 o'clock position, and then use another segment of barbed suture to suture continuously clockwise.
[0042] 6. Finally, converge at 9 o'clock with the previous suture and tie them together to complete the suturing.
[0043] The above - mentioned are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well - known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
