[0030] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] See also Figure 1-Figure 4 A sheath tube for suturing includes a sheath tube body 1, a hose 2, an elastic membrane 3 and a silicone block 4. Specifically, a notch 5 is provided on both sides of the sheath tube body 1, and the two notches 5 are both inclined structures, and the top ends of the two notches 5 are respectively located on both sides of the sheath tube body 1, and the bottom ends of the two notches 5 are also respectively located on both sides of the two notches 5, so that the projections of the two notches 5 on the vertical plane are distributed in an X-shaped structure.

[0035] There are two hoses 2, which are respectively arranged corresponding to the two slots 5. The extension direction of the hose 2 is consistent with the extension direction of the slot 5, and the cross-section of the hose 2 is C-shaped. The opening side of the hose 2 is close to the slot 5, so that the inside of the hose 2 can be entered from the outside of the sheath body 1 through the slot 5.

[0036] An elastic membrane 3 is provided on both sides of each hose 2, one side of the elastic membrane 3 is tightly connected to the outer wall of the hose 2, and the other side of the elastic membrane 3 is tightly connected to the inner wall of the sheath body 1. During the stage of the sheath body 1 performing interventional treatment, the elastic membrane 3 can bind the hose 2 to the inner wall of the sheath body 1.

[0037] A silicone block 4 is disposed on both sides of the sheath tube body 1 , respectively. The two silicone blocks 4 are close to the bottom ends of the two notches 5 .

[0038] In this embodiment, first, an inclined slot 5 is opened on both sides of the sheath body 1, and a hose 2 is arranged in the slot 5. The outer wall of the hose 2 and the inner wall of the sheath body 1 are connected by an elastic mold, and a silicone block 4 is arranged at the end of the sheath body 1.

[0039] During the process of interventional treatment, the hose 2 is tightly attached to the inner wall of the sheath tube body 1 , so that the inner wall of the sheath tube body 1 is unobstructed.

[0040] During use, one end of the suture is passed through the opening at the end of the lead needle, and then the end of the lead needle with the opening is inserted from the top of the notch 5 and extends along the hose 2. The end of the lead needle squeezes the inside of the hose 2, the elastic membrane 3 widens, and the hose 2 becomes straight, so that the lead needle can smoothly pass through the notch 5 and the hose 2. After the lead needle passes through the bottom of the notch 5, it pierces the blood vessel wall, and the end of the lead needle is inserted into the silicone block 4, and then the lead needle is pulled out. The friction of the silicone block 4 on the suture makes the suture remain in the silicone block 4.

[0041] Then the other end of the suture is passed through the opening of the end of the guide needle again, and the guide needle is inserted from the top of another notch 5, and the above action is repeated.

[0042] After the two thread feeds of the guide needle are completed, the sheath is withdrawn from the blood vessel, so that the sheath pulls the two ends of the suture out of the wound and manually knots them, thereby completing the suturing.

[0043] This technical solution can directly utilize the sheath tube of interventional treatment to perform suturing work, and the operation is simple.

[0044] In addition, the guide needle involved in this embodiment is a prior art, and its structure is as shown in the guide needle in Chinese Patent: Fascia Suture Device (Application Number: CN201510316186.6).

[0045] In one specific embodiment:

[0046] The silicone block 4 is arranged on one end of a support plate 6, the other end of which is connected to the outer wall of the sheath body 1, and the support plate 6 has a certain elasticity, and the connection point between the support plate 6 and the sheath body 1 is far away from the bottom end of the slot 5 relative to the other end thereof.

[0047] A driving rod 7 is slidably disposed on the sheath body 1 . The length direction of the driving rod 7 is the same as that of the sheath body 1 , and one end of the driving rod 7 is disposed between the support plate 6 and the inner wall of the sheath body 1 .

[0048] In this embodiment, the silicone block 4 is set on the support plate 6. When in use, the driving rod 7 is pushed downward to move the end of the driving rod 7 toward the connection point between the support plate 6 and the sheath body 1, so that the support plate 6 is tilted on the sheath body 1, and the silicone block 4 is pushed away from the sheath body 1, so that the end of the lead needle can just penetrate into the silicone block 4.

[0049] When the sheath body 1 needs to be pulled out, the driving rod 7 is first moved outward so that the support plate 6 drives the silicone block 4 and the end of the suture to be close to the outer wall of the sheath body 1, so that the end of the suture can be smoothly brought out when the sheath body 1 moves outward.

[0050] In another specific embodiment:

[0051] A slide groove is arranged outside the sheath body 1, and the driving rod 7 is arranged in the slide groove, and the top and bottom ends of the same slide groove are respectively close to the ends of the two notches 5. The slide groove is arranged to prevent the outer diameter of the sheath from increasing.

[0052] A driving ring 8 is arranged on the end of the sheath body 1 away from the silicone block 4, and the end of the driving rod 7 away from the support plate 6 is fixedly arranged on the driving ring 8, and an annular groove is also arranged on the outside of the sheath body 1, and the driving ring 8 is slidably arranged in the annular groove.

[0053] In this embodiment, the driving ring 8 is provided to drive the two driving rods 7 to move at one time and to make the displacements of the two driving rods 7 equal. The annular groove and the sliding groove have the same function.

[0054] In another specific embodiment:

[0055] A U-shaped pressing piece 9 is provided at one end of the driving rod 7 away from the driving ring 8, and the support plate 6 passes through the pressing piece 9. In this embodiment, when the driving rod 7 moves downward, the support plate 6 can be tilted by the top end of the pressing piece 9, and when the driving rod 7 moves upward, the support plate 6 can be pressed against the outer wall of the sheath body 1 by the bottom end of the pressing piece 9.

[0056] In another specific embodiment:

[0057] The support plate 6 is L-shaped, one end of the support plate 6 is connected to the outer wall of the sheath body 1, and this end of the support plate 6 is arranged in the vertical direction, the other end of the support plate 6 is arranged in the horizontal direction, and a silicone block 4 is arranged on this end of the support plate 6, so that the silicone block 4 can be exactly located in the extension direction of the slot 5.

[0058] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
