Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to a tail thread retracting and releasing device for double-needle suture threads in thoracoscopic surgery. Background Art

[0002] With the continuous development of thoracoscopic technology, some more complicated operations can also be completed under laparoscopy, such as tracheal and carinal resection and reconstruction, bronchial or pulmonary vascular sleeve resection, and other blood vessel and organ resection and reconstruction. These operations often require more complicated sutures. Completing the anastomosis of the trachea or blood vessels is the key to the success of the operation. Such sutures require "double-needle" sutures, that is, sutures with needles on both ends. The most commonly used is Johnson & Johnson's prolene suture. This complex suture is prone to failure. The most common reason is "winding" and "threading" during suture, resulting in unsuccessful anastomosis. When suturing, multiple coils are in a narrow space, and the tail end is the easiest to be wrapped, especially for single-port thoracoscopic technology, because the tail end must also be placed outside the incision, which is a great test for medical personnel performing the operation. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a tail thread retracting device for double-needle sutures in thoracoscopic surgery, comprising: a top, a spacer, a bottom, a side wall and a double-needle suture, the top being connected to the spacer through an upper column, the bottom being connected to the spacer through a lower column, protrusions being arranged on the upper end surface and the lower end surface of the side wall, slots being arranged on the top and the bottom and being connected to the protrusions of the side wall, a roller being arranged on the lower column, one end of the double-needle suture being arranged and connected to the upper column, the suture winding of the double-needle suture being arranged on the roller, and the other end of the double-needle suture being arranged outside the roller.

[0004] Furthermore, the spacer is provided with an opening slot for the double needle suture to pass through.

[0005] Furthermore, the side wall is detachable.

[0006] Furthermore, the double-needle stitching can be stored separately.

[0007] The advantages of the present invention are: the present invention is easy to use, avoids the looping of the tail thread during suturing, makes suturing convenient, improves the success probability of suturing, improves the operability of the operation, reduces the risk to the patient, and also reduces the risk of wound suturing for medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The drawings constituting a part of this application are used to provide a further understanding of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention. In the drawings:

[0009] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0010] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0011] like Figure 1 As shown, a tail thread collecting and releasing device for double-needle sutures in thoracoscopic surgery comprises a top 1, a spacer 2, a bottom 3, a side wall 7 and a double-needle suture 8, wherein the top 1 is connected to the spacer through an upper column 4, the spacer 2 is provided with an open groove 9 for the double-needle suture 8 to pass through, the bottom 3 is connected to the spacer 2 through a lower column 5, the upper end surface and the lower end surface of the side wall 7 are provided with protrusions, the top 1 and the bottom 3 are provided with a card slot 10 connected to the protrusion of the side wall 7, and the side wall is detachable, a rotatable drum 6 is provided on the lower column 5, one end of the double-needle suture 8 is provided and connected to the upper column 4, the suture winding of the double-needle suture 8 is arranged on the drum 6, the other end of the double-needle suture 8 is arranged outside the drum 6, and the double-needle suture 8 can be stored separately.

[0012] Before surgical suturing, the side wall 7 is first disassembled, and one end of the needle of the double-needle suture 8 is fixedly set on the upper column 4. The suture of the double-headed suture 8 is wound on the roller 6 through the open groove 9 on the spacer 2. After the suture is wound, the side wall 7 is installed on the top 1 and the bottom 3 through the protruding part of the side wall 7. Because the roller 6 is rotatable, during the suturing process, the present invention is placed in the chest cavity to avoid the tail thread being wrapped during suturing, making suturing convenient and the suture can be pulled out evenly.

[0013] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
