Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument related technical field, more accurate to say under the thoracoscope gas pipe sutures device. BACKGROUND

[0002] The thoracoscope under lung sleeve type resection is the key means of treating specific position lung tumor, and the tracheal anastomosis operation is extremely important and difficult, and the traditional suture mode and instrument have many defects. The existing tracheal suture mode process is more cumbersome, and the anastomosis time is long, and the tracheal stump is repeatedly pulled during the anastomosis process, the tension of each anastomosis point is uneven, which can increase the risk of anastomosis leakage and other related complications. The existing suture instrument mainly has 3-0 prolene suture and bidirectional barbed line, but there are certain limitations in the use process. The anchoring effect of 3-0 prolene suture is poor, if the suture line is tightened together after suture, it is difficult to avoid the influence of loose suture line on the suture process. The size of the needle of the existing 3-0 prolene suture is only 17mm and 26mm. When suture the front wall of trachea, it is particularly difficult to pull out the 17mm needle from the two tracheal stumps which are gradually tightened together. When suture the back wall of trachea, the direction of the suture needle is from the outside to the inside of the bronchus, and due to the small bronchus cavity and insufficient operation space, the 26mm needle is not convenient to operate and may damage the blood vessels under the back wall.

[0003] The bidirectional barbed line can avoid the influence of loose suture line on the suture process, has good anchoring effect, and can tighten the anastomosis port while suture, but the midpoint of the barb in different directions of the existing bidirectional barbed suture is difficult to distinguish in the chest cavity, which will lead to the uncertainty of the line distance, greatly increase the risk of anastomosis failure, and may cause irreversible damage to the tracheal wall.

[0004] In summary, the existing thoracoscope tracheal suture instrument and suture mode have significant limitations in operation, suture quality and safety, and need to be improved to improve the quality and safety of the operation and improve the prognosis of the patient. UTILITY MODEL CONTENT

Based on the embodiment in the utility model, all other embodiments that the ordinary skilled person in the art obtains without making creative labor all belong to the range of protection of the utility model.

[0025] As Figure 1The thoracoscope tracheal suturing device comprises a suture 1, a first suture needle 2 and a second suture needle 3 connected to the two ends of the suture 1 respectively, the first suture needle 2 and the second suture needle 3 are both circular needles with an arc of 1 / 2 circle, and the length of the first suture needle 2 is smaller than that of the second suture needle 3. The suture 1 has a first section 12 and a second section 13 which are butted at the end, the first section 12 is connected to the first suture needle 2 in an embedded manner, the second section 13 is connected to the second suture needle 3 in an embedded manner, and the first section 12 and the second section 13 are both provided with a plurality of barbs, and the barbs on the first section 12 and the second section 13 are in opposite directions. Preferably, the first section 12 and the second section 13 have different colors, which facilitates the identification during the operation; preferably, the first section 12 is blue and the second section 13 is yellow.

[0026] Specifically, the length of the suture 1 is 50 cm, the length of the first suture needle 2 is 17 mm, and the length of the second suture needle 3 is 26 mm.

[0027] Referring to Figure 2 , the first section 12 is provided with a plurality of first barbs 121 arranged in a 360° spiral along the axis direction of the first section 12, the barb heads of the first barbs 121 extend away from the first suture needle 2, and the first barbs 121 are preferably fishbone-shaped barbs.

[0028] Referring to Figure 3 , the second section 13 is provided with a plurality of second barbs 131 arranged in a 360° spiral along the axis direction of the second section 13, the barb heads of the second barbs 131 extend away from the second suture needle 3, and the second barbs 131 are preferably fishbone-shaped barbs.

[0029] Referring to Figures 5 to 8 , the steps of using the thoracoscope tracheal suturing device to suture the trachea comprise:

[0030] (1) using the first suture needle 2 to start suturing the posterior wall of the trachea;

[0031] (2) operating the first suture needle 2 to pull the suture 1 to the junction of the first section 12 and the second section 13 to the incision position of the trachea, pulling the first suture needle 2 out of the incision of the trachea, and making the trachea anastomosis at the junction of the different colors of the suture;

[0032] (3) operating the first suture needle 2 to complete the suture of the posterior wall of the trachea using the first section 12;

[0033] (4) using the second suture needle 3 to start suturing the anterior wall of the trachea;

[0034] (5) operating the second suture needle 3 to complete the suture of the anterior wall of the trachea using the second section 13, and tightening the suture 1 and knotting after the first suture needle 2 and the second suture needle 3 meet, to complete the tracheal suture.

[0035] In step (1), the small first suture needle 2 can be used to suture the posterior wall of the trachea in a narrow space, and reduce the risk of injury to the surrounding blood vessels. In step (2), the first suture needle 2 is pulled out of the incision of the trachea, and the anastomosis of the trachea is located at the junction of different colors of the suture, which can prevent the knots from being entangled with each other and provide a certain tension, and can avoid the reverse barb from damaging the trachea and causing anastomosis failure due to the suture being too long or too short. In step (4), the larger second suture needle 3 is used to continuously suture the anterior wall, and the larger needle is convenient to rotate into the trachea and allows suture of both sides by a single movement. The 360° spiral fishbone-shaped barb on the suture 1 can produce excellent anchoring effect, reduce the shearing force of the barb on the tissue in the same plane, solve the problem of the suture from being loose in the tissue, and eliminate the influence of the cutting barb suture on the tensile strength of the suture, and provide more reliable tissue gripping and smaller tissue damage.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
