[0046] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0047] Example 1

[0048] A specific embodiment of the present invention discloses a rotatable suture staple for endoscope, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, it includes: a clamping cylinder 101, a fixed column 102, a threading ring 103 and a spiral connecting portion 104; specifically, the clamping cylinder 101 and the spiral connecting portion 104 are respectively fixedly arranged at the upper and lower ends of the fixed column 102; the threading ring 103 is rotatably sleeved on the outer side of the fixed column 102, and the side of the threading ring 103 is provided with an arc-shaped threading hole 105 passing through the front and back, and the suture thread can be inserted from one end of the arc-shaped threading hole 105 and passed out from the other end of the arc-shaped threading hole 105.

[0049] Specifically, the clamping tube 101 can be snapped and detachably mounted on the end of the introduction structure; the introduction structure can be inserted into the endoscope channel and, after engaging with the clamping tube 101, can drive the suture staple 1 to rotate. For example, the introduction structure can adopt the introduction structure of an existing releasable metal clip (the portion without the clip is the introduction structure). In this embodiment, the introduction structure of an existing disposable metal clip is a snap-on connection that is drag-released and can serve as the introduction structure for the suture staple 1 of this embodiment.

[0050] Furthermore, in order to achieve a good clamping effect between the clamping cylinder 101 and the introduction structure, a plurality of circular clamping holes 106 are provided on the circumferential side of the clamping cylinder 101; and the clamping holes 106 can be engaged with the spherical clamping beads 205 of the introduction structure.

[0051] Furthermore, when the suture staple 1 is rotated as a whole, the spiral connection portion 104 can be screwed into the tissue surrounding the wound surface.

[0052] Furthermore, if Figure 3 、 Figure 4 As shown, an arc-shaped threading hole 105 is provided on the side of the threading ring 103, and the threading ring 103 is rotatably connected to the fixing column 102. When the suture thread is passed through the arc-shaped threading hole 105 and connected to the threading ring 103, the rotation of the suture nail 1 body will not cause the threading ring 103 and the suture thread to rotate, which can effectively prevent the thread from being entangled.

[0053] In this embodiment, Figure 2 、 Figure 3 、 Figure 4 As shown, a circular annular groove 107 is provided on the outer side of the fixed column 102, and correspondingly, a circular annular rotating convex ring 108 is provided on the inner side of the threading ring 103. The rotating convex ring 108 has the same shape and size as the annular groove 107. The rotating convex ring 108 is inserted into the annular groove 107, so that the threading ring 103 can be rotatably installed on the outer side of the fixed column 102.

[0054] Alternatively, the threading ring 103 is rotatably sleeved on the outside of the fixing column 102 via a micro bearing.

[0055] Furthermore, if Figure 5 As shown, the arc-shaped threading hole 105 is provided on one side of the threading ring 103 and passes through the threading ring 103. Preferably, the central angle of the arc of the arc-shaped threading hole 105 is not less than 45°.

[0056] During implementation, after a single rotatable suture staple is screwed into human tissue (tissue beside the wound in the digestive tract), the suture is tightened, and the arc-shaped threading hole 105 plays a certain role in tightening the suture and preventing it from retracting after tightening. Then, multiple rotatable suture staples are screwed in and installed to tighten the wound tissue. After the suture staples are completely tightened, the spacing between the multiple suture staples is shortened to a minimum, completing the tightening of the large wound. Then, a wire clip is placed at the end of the suture staples or the end suture staples are tied to achieve the positioning of the multiple suture staples. Once the wound (circular, elliptical or irregular wound) is tightened to a near-linear wound, the wound is completely closed by inserting a common metal clip into the endoscope clamp channel, thereby achieving simple, efficient and safe wound suture.

[0057] The release method of the rotatable suture staple for endoscope in this embodiment can adopt the same release method as the existing disposable releasable metal clip to realize the release of a single suture staple. The suture staple of the utility model is disposable. After installing and releasing a suture staple in human tissue, a new suture staple is immediately used to penetrate the suture thread (the same thread) to continue suturing. After at least one new suture staple is screwed into the human tissue again, the suture thread is tightened to shrink the large wound. The operation is convenient, and there is no need to worry about the loading problem of multiple suture staples when using it.

[0058] Example 2

[0059] In a specific embodiment of the present invention, a rotatable suturing device for an endoscope is provided, which is used to implement the installation and release of the rotatable suturing staple for an endoscope in Example 1.

[0060] In this embodiment, Figure 6 、 Figure 7 、 Figure 10As shown, in this embodiment, the endoscopic rotatable suturing device includes: a suturing staple 1 and an introduction structure. The suturing staple 1 is the rotatable suturing staple for endoscope in Example 1; the introduction structure includes: an introduction sleeve 2 and a push rod 3.

[0061] Specifically, if Figure 7 、 Figure 8 、 Figure 9 As shown, a locking boss 202 is provided at the end of the introduction sleeve 2, and an operating handle 201 is provided at the other end of the introduction sleeve 2. The operating handle 201 and the locking boss 202 are integrally formed with the main structure of the introduction sleeve 2.

[0062] Preferably, the main body of the introduction sleeve 2 is a bendable and non-twistable guide wire structure; the engaging boss 202 is a hard plastic or metal structure; and the operating handle 201 is made of hard plastic.

[0063] Preferably, the push rod 3 is made of bendable hard plastic or soft alloy.

[0064] Specifically, if Figure 8 As shown, the engaging boss 202 is used to engage with the engaging cylinder 101 of the suture staple 1; during implementation, the engaging cylinder 101 is sleeved on the outside of the engaging boss 202, and the two are engaged with each other, and then rotating the operating handle 201 can realize the rotation of the suture staple 1; and the suture staple 1 can rotate forward or reverse.

[0065] Furthermore, in order to achieve a better engagement effect between the engaging boss 202 and the engaging cylinder 101, in this embodiment, as shown in FIG. Figure 8 As shown, a plurality of spherical beads 205 are provided in the circumferential direction of the outer side of the engaging boss 202 ; specifically, the spherical beads 205 protrude from the outer surface of the engaging boss 202 , and the spherical beads 205 can be engaged with the engaging holes 106 on the side of the engaging cylinder 101 .

[0066] Preferably, the spherical card bead 205 is made of metal or hard plastic.

[0067] Furthermore, a portion of the spherical card bead 205 is embedded in the interior of the engaging boss 202 ; the spherical card bead 205 is fixedly connected to the engaging boss 202 , or the spherical card bead 205 is rotatably installed in the card bead installation groove of the engaging boss 202 .

[0068] When implementing, if Figure 12As shown, when the clamping cylinder 101 is sleeved on the outside of the clamping boss 202, the spherical clamping bead 205 is clamped into the clamping hole 106. During the process of the spherical clamping bead 205 being clamped into the clamping cylinder 101, the spherical clamping bead 205 or the clamping cylinder 101 undergoes a slight elastic deformation. As a result, when the spherical clamping bead 205 is engaged with the clamping hole 106, when no external force is applied, the spherical clamping bead 205 will not be separated from the clamping cylinder 101 of the suture staple 1. As a result, the suture staple 1 can be driven to rotate synchronously through the introduction sleeve 2, thereby achieving the screwing in or screwing out of the digestive tract cavity tissue.

[0069] like Figure 8 As shown, a push-out hole 204 is provided inside the engaging boss 202 ; further, the diameter of the push-out hole 204 is smaller than the inner diameter of the introduction sleeve 2 .

[0070] Furthermore, if Figure 6 、 Figure 13 As shown, a push rod 3 is sleeved and installed inside the introduction sleeve 2.

[0071] In this embodiment, Figure 10 As shown, the push rod 3 includes: a push rod body 301, a release handle 303 and a cylindrical push platform 304; specifically, the release handle 303 and the cylindrical push platform 304 are fixedly installed at both ends of the push rod body 301; the push rod body 301 can penetrate into the interior of the introduction sleeve 2, and the cylindrical push platform 304 can penetrate into the interior of the push platform outlet hole 204.

[0072] Furthermore, the length of the cylindrical push platform 304 is greater than the length of the push platform outlet hole 204; when the cylindrical push platform 304 extends out of the push platform outlet hole 204, it can push the suture nail 1 to separate from the introduction sleeve 2, that is, the thrust of the cylindrical push platform 304 of the push rod 3 pushes the solid fixed column 102, thereby driving the clamping tube 101 and the spherical clamping bead 205 out of the clamping state, thereby releasing the suture nail 1. Figure 13 shown.

[0073] Furthermore, in order to facilitate the cylindrical pusher 304 to apply thrust to the fixed column 102 of the suture staple 1, in this embodiment, a threaded section 302 is provided on the outside of the push rod body 301, and the diameter of the threaded section 302 is larger than that of the push rod body 301; correspondingly, a threaded hole 203 is provided at the handle end of the introduction sleeve 2, and the diameter of the threaded hole 203 is larger than the inner diameter of the introduction sleeve 2; the threaded section 302 can be screwed together with the threaded hole 203, and during the process of the two gradually screwing together, the push rod 3 is displaced from the handle end of the introduction sleeve 2 to the engaging end, and then the cylindrical pusher 304 gradually extends out of the pusher exit hole 204.

[0074] Specifically, the release handle 303 is arranged perpendicular to the push rod body 301, which can increase the lever arm of the rotational torque, thereby facilitating the rotation of the push rod 3 and reducing the operating force required to separate the suture staple 1 from the introduction sleeve 2.

[0075] Furthermore, in order to facilitate operation, a push rod through hole 206 is provided at the outer end of the operating handle 201. The diameter of the push rod through hole 206 is larger than the diameter of the threaded section 302, so that the push rod body 301 and the threaded section 302 of the push rod 3 can pass through the push rod through hole 206 and then penetrate into the interior of the introduction sleeve 2.

[0076] In this embodiment, Figure 11 As shown, before the suture staple 1 is engaged with the introduction sleeve 2, the cylindrical pusher 304 of the push rod 3 retracts into the inside of the pusher exit hole 204, thereby enabling the connection between the clamping tube 101 of the suture staple 1 and the introduction sleeve 2.

[0077] When implementing, if Figure 12 、 Figure 13 As shown, when the suture staple 1 is connected to the introduction sleeve 2, the suture staple 1 can be sent into the digestive tract cavity through the introduction sleeve 2 and the clamp channel of the endoscope and screwed with the tissue around the wound surface of the digestive tract cavity; after the suture staple 1 is installed in place, by pushing or rotating the release handle 303 of the push rod 3, the cylindrical push platform 304 at the end of the push rod 3 is extended from the push platform outlet hole 204, thereby pushing the suture staple 1 to separate from the introduction sleeve 2, completing the release and installation of the suture staple 1.

[0078] After the rotatable suture staple for endoscope of the present invention is engaged with the introduction sleeve 2, the rotation of the suture staple 1 can be realized by rotating the operating handle 201, and the function of forward and reverse bidirectional rotation of the suture staple 1 can be realized. Forward rotation can completely screw the suture staple 1 into the tissue to be sutured. Once there is a deviation in the position or the position needs to be adjusted, the suture staple 1 can be completely screwed out by reverse rotation. When the suture staple 1 is driven into the tissue and the position and depth are appropriate, the release handle 303 is operated to release the suture staple 1. After release, the introduction structure can be taken out. The above process can be repeated to continuously install multiple suture staples 1, so that the suture staple 1 and the suture thread maintain a continuous tightening effect on the large wound, and the large wound can be clamped with a metal clip.

[0079] The rotatable suturing device for endoscope of the utility model has the functions of being "disposable, rotatable, and easy to use", and can realize simple, efficient and safe wound suturing, so as to further improve the effectiveness and safety of digestive endoscopic surgery.

[0080] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
