Description

Technical Field

[0001] This invention belongs to the field of medical devices, specifically relating to a suture device, a suture mechanism, a suture apparatus, and an endoscopic suturing method. Background Technology

[0002] Gastrointestinal defects, especially perforations, are a common problem encountered during flexible endoscopic minimally invasive surgery. Currently, endoscopic suturing methods include endoscopic metal clip closure, purse-string sutures using nylon cords and endoscopic metal clips, and some advanced suturing devices reported abroad. The first two are commonly used methods; however, the opening angle and closure stability of endoscopic metal clips are limited, generally used for closing small defects. Purse-string sutures using nylon cords and metal clips can repair larger perforations, but their flexibility and stability are inferior, and the procedure is more complex. With the development of flexible endoscopic minimally invasive techniques, the above defect repair and suturing methods are no longer sufficient to meet the needs of surgery. Summary of the Invention

[0017] In one embodiment, a clamp is movably mounted on the base, the clamp being located between the first and second colliders, and the rear end of the clamp is connected to a control cable.

[0018] In one embodiment, a third linear guide portion is provided on the seat body, and a fourth linear guide portion is provided on the second collision member. The second collision member is movably mounted on the seat body and slides in cooperation with the third linear guide portion and the fourth linear guide portion.

At least one of the first or second opposing members is translated towards each other under external force. The tip of the delivery tube penetrates the human tissue under the action of the translating movement of the first and second opposing members, releasing the suture on both sides of the tissue, thus suturing the tissue. This plug-type suture device allows for rapid suturing of the human digestive tract, is very convenient to use, and can be combined with endoscopy to achieve a minimally invasive effect. In this invention, since the first opposing member is guided by the first and second linear guides, and moves by translation during suturing, it reduces tissue displacement during suturing, resulting in high suturing accuracy and reliability, and ensuring the effectiveness of the suturing.

[0080] Example 1

[0081] like Figures 1 to 13 As shown, the plug-type suture device, as described in this embodiment, is mainly used for suturing the digestive tract. It includes: a guide tube 210, clamps 410, an endoscope 350, a first operating component 510, a second operating component 520, a third operating component 530, and a plug-type suture device.

[0082] The guide tube 210 has a first guide cavity 211, a second guide cavity 212, and a third guide cavity 213. A first push-pull member 312 is disposed in the second guide cavity 212. In this embodiment, the first push-pull member 312 is made of a guide steel wire with a certain degree of elasticity and rigidity, and its function will be described later. An endoscope 350 is disposed in the third guide cavity 213, and an endoscope cavity 351 is disposed in the endoscope cavity 351. A control cable 313 is disposed in the endoscope cavity 351. The guide tube 210 is elastic, can be bent, and is not easily deformed. It can be integrally formed from a highly elastic material, or a pipe with an embedded spring, or other pipe components that meet the requirements of elastic performance. The guide cavity plays a guiding and limiting role. Its arrangement allows the first push-pull member 312 to bend adaptively in a bent state, effectively transmitting the pushing and pulling force.

[0083] The tip of the endoscope 350 is inserted into the fixing hole 113 on the seat 110 of the suture device, and can be connected to the seat 110 of the suture device by interference fit or by other connectors. Other cavities can also be provided inside the endoscope 350 as needed, such as for image transmission or for gas or liquid delivery. The clamp 410 can pass through the working channel of the endoscope 350 and exit from the fixing hole 113 of the seat 110 of the suture device, and is controlled by the operating cable 313.

[0084] The rear end of the suture device is provided with a first operating member 510, a second operating member 520 and a third operating member 530. The first operating member 510 can push, pull and lock the conveying control member 311. The second operating member 520 can push and pull the first push-pull member 312 to control the first collision member 120 of the suture device (the specific structure and principle of the suture device will be described below). The third operating member 530 acts on the control cable 313 to control the clamp 410.

[0085] The following is a detailed description of the plug-type suture device:

[0086] Please also focus on combining Figures 3 to 6 , Figure 13As shown, the suture device includes a base 110 and a first opposing member 120. A first linear guide portion 111 is provided on the base 110, and a second linear guide portion 121 is provided on the first opposing member 120. The first opposing member 120 is movably mounted on the base 110 and slides with the second linear guide portion 121 through the first linear guide portion 111. A second opposing member 130 is also provided on the base 110. The first opposing member 120 and the second opposing member 130 are opposite to each other. A conveying pipe 125 for placing the suture 600 is provided on the first opposing member 120, and a suture part 132 is provided on the opposite side of the other one. The front end of the conveying pipe 125 has a pipe tip 1251. A hollow conveying channel 1251 is provided inside the conveying pipe 125, and a conveying control member 311 is also provided inside the conveying channel 1251.

[0087] The conveying pipe 125 is divided into a fixed section, a flexible section and an extension section. The fixed section is located between the first collision member 120 and the second collision member 130. The rear end of the fixed section is the flexible section. When the first collision member 120 moves, the flexible section will bend and deform accordingly to adapt to the movement of the first collision member 120. In particular, the flexible section can bend and must ensure that its conveying channel 1251 does not deform. The remaining part is the extension section, which is located in the guide cavity 210.

[0088] During suturing, the plug-type suture device is placed at the site of the human tissue to be sutured, with the tissue positioned between the first impactor 120 and the second impactor 130. At least one of the first impactor 120 or the second impactor 130 is translated towards each other under external force. The plug-type suture portion 132 on the second impactor 130 includes two side stops 133, with an insertion port 134134 between the two side stops 133. The tip 1251 of the delivery pipe 125 penetrates the human tissue to be sutured under the action of the translating movement of the first impactor 120 and the second impactor 130. Then, the first plug portion 610 and the second plug portion 620 of the suture device 600 are released on both sides of the tissue to be sutured, thereby suturing the human tissue. This plug-type suture device allows for rapid suturing of the human digestive tract, is very convenient to use, and can be used in conjunction with an endoscope 350 to achieve a minimally invasive effect. In this invention, since the first collision member 120 is guided by the first linear guide part 111 and the second linear guide part 121, the first collision member 120 moves by translation, which can reduce the displacement of human tissue during suturing, resulting in high suturing accuracy and reliability, and also ensuring the suturing effect.

[0089] In this embodiment, the function of the first linear guide portion 111 and the second linear guide portion 121 is to achieve linear translational guidance between the first collider 120 and the seat 110. This can be achieved by using a linear guide groove and a linear guide rail, or by using a linear guide rod or other methods for guidance. To improve the guidance accuracy, multiple linear guide grooves and linear guide rails can also be used in combination. In this embodiment, the first collider 120 includes an end plate 123 and side arms 124 located on both sides of the end plate 123. The second linear guide portion 121 is located on the outer side of the two side arms 124.

[0090] The translation of the first collision member 120 is controlled by the first push-pull member 312. In this embodiment, a first rotating part 161 is provided on the seat 110, and a first transmission member 163 is movably mounted on the first rotating part 161. The first transmission member 163 is an L-shaped rod with a closed slot at one end and a round hole at the other end. A force-applying part 166 (i.e., a first groove) is provided at the rear end of the first transmission member 163, and a force-transmitting part 167 is provided at the front end. The first rotating part... 161 is a first pin on the seat 110. The first transmission member 163 is movably mounted on the seat 110 through the first rotating part 161. The front end of the first push-pull member 312 is provided with a fifth pin 335, which is slidably engaged with the first sliding groove. A second pin 332 is provided on the first collision member 120. A non-enclosed guide groove 1231 is provided on the first collision member 120, and the second pin 332 is slidably engaged with the guide groove 1231.

[0091] In this embodiment, by operating the second operating member 520 and driving the first transmission member 163 to rotate through the first push-pull member 312, the longitudinal translational movement of the first push-pull member 312 along the endoscope body direction of the endoscope 350 is transformed into the lateral translational movement of the first collision member 120, so that the suture member 600 can accurately puncture the tissue to be sutured and realize the suturing of human tissue.

[0092] To reduce the swaying of the first push-pull member 312 and improve the accuracy of the stitching, a limiting member 340 is connected to the seat 110. A limiting hole 341 is provided on the limiting member 340. The front end of the first guide tube 216 is limited by the limiting hole 341, which reduces the lateral swaying of the first push-pull member 312.

[0093] In this embodiment, when the first collision member 120 is in the open state, it needs to have a certain mating distance with the seat 110. In the sewn state, in order to avoid interference between the front end of the first collision member 120 and the seat 110, a clearance portion 117 is provided on the seat 110. The clearance portion 117 is located in the longitudinal extension direction of the second straight guide portion 121.

[0094] In this embodiment, the guide tube 210 is processed separately and used in conjunction with the endoscope 350. Alternatively, a first guide cavity 211 and a second guide cavity 212 can be provided inside the endoscope 350. It can also be understood that the guide tube 210 and the endoscope 350 can be fixed together by means of straps or other structures.

[0095] It should be noted that:

[0096] In this invention, when the first collider 120 is translated by the second operating member 520, its transmission structure is not limited to the aforementioned method. In the following embodiments, possible transmission methods will be described. It can be understood that the translation of the first collider 120 relative to the second collider 130 can also be achieved by other similar structures, and the human tissue can be sutured by the suture member 600. All of these are within the scope of protection of this application.

[0097] Please focus on combining Figures 7 to 9 As shown, the steps for suturing human tissue are as follows:

[0098] like Figure 7 As shown, by operating the second operating member 520, the first collision member 120 is positioned flush with the longitudinal direction of the seat body 110. At this time, the suture 600 is located in the delivery channel. This state is the insertion state of the plug-type suture. The lateral dimension of the plug-type suture is small to facilitate its insertion and avoid the plug-type suture from abrading the mucosal tissue of the digestive tract lumen.

[0099] like Figure 8 As shown, by operating the second operating member 520, the first collision member 120 is placed in the outer position. This state is the open state of the suture device. The suture device has a large lateral dimension, which makes it convenient for the clamp 410 to clamp the human tissue to be sutured. It also leaves enough space for the translation of the first collision member 120. The clamp 410 clamps and pulls the human tissue to be sutured into the area between the first collision member 120 and the second collision member 130.

[0100] like Figure 9 As shown, this state is the suturing state of the suture device. By operating the second operating member 520, the first collision member 120 is quickly moved inward and the suture 600 is driven to collide with the second collision member 130. During the translation, the suture 600 penetrates the tissue to be sutured. By operating the first operating member 510, the conveying control member 311 pushes the suture 600 and releases it on both sides of the tissue to be sutured, thus achieving the effect of suturing human tissue. In order to make the push of the suture 600 smoother, before the suturing state, the suture 600 avoids the bend at the front end of the conveying pipe 125 as much as possible. This is because before the suturing state, the bend curvature of the flexible section of the conveying pipe 125 is large, which will hinder the smooth movement of the suture 600 in the conveying pipe 125.

[0101] The aforementioned three states are not necessarily the states in which the stapling device described in this embodiment is used. For example, in the insertion state, the first colliding member 120 can be positioned slightly inside the seat 110. To reduce damage to human tissue from the outer surface of the stapling device, each component of the stapling device is designed with smooth rounded corners or transitional curved surfaces as much as possible.

[0102] Please focus on combining Figures 10 to 13 As shown, in this embodiment, the suture 600 includes a first plug 610, a second plug 620, and a locking member 630 connecting the first plug 610 and the second plug 620. In this embodiment, the locking member 630 is a tether, and a buckle 640 is also provided at the end of the locking member 630. The conveying control member 311 includes at least a pushing outer tube 3111 and a traction member 3112. The traction member 3112 is located inside the pushing outer tube 3111, and the outer end of the traction member 3112 is an elastic and flexible guide wire. The traction member 3112 passes through both the first plug 610 and the second plug 620 of the suture 600. The pushing outer tube 3111 is located on the rear side of the suture 600, and the rear end of the pushing outer tube 3111 passes through the first guide cavity 211.

[0103] The first plug 610 and the second plug 620 are sequentially threaded onto the traction member 3112, with the first plug 610 located at the distal end of the traction member 3112. The traction member 3112 can be made of shape memory material. During suturing, the push tube 3111 pushes the first plug 610 and the second plug 620 forward. During this forward movement, the push tube 3111 and the traction member 3112 work together. When releasing the first plug 610 or the second plug 620, the push tube 3111 is pushed outward and the traction member 3112 is pulled backward, thereby releasing the first plug 610 and the second plug 620 to both sides of the tissue to be sutured. Furthermore, after the first bolt 610 and the distal end of the traction member 3112 are pushed out of the delivery pipe 125 by the pusher tube 3111, the distal end of the traction member 3112 bends to the side of the delivery pipe 125 in the axial direction, thereby causing the first bolt 610 to also be in a lateral position. When the traction member 3112 is pulled back, the first bolt 610 that was pushed out can be prevented from being pulled back into the delivery pipe 125. At the same time, in order to improve the sewing effect, at least two locking members 630 are provided between the first bolt 610 and the second bolt 620. After the first bolt 610 and the second bolt 620 are released into place, the pusher tube 3111 can be used to press against the rear end of the first bolt 610 and the second bolt 620. By pulling the fastener 640 of the sewing piece 600, the first bolt 610 and the second bolt 620 can be tightened to achieve reliable sewing and tightening of the device to be sewn.

[0104] It should be noted that when at least one of the first collider 120 and the second collider 130 undergoes lateral translation, the impact can be a direct force between the two or an indirect force between them. In this embodiment, the first collider 120 and the second collider 130 indirectly impact each other through a suture staple. It can be understood that the first collider 120 and the second collider 130 may also not generate direct or indirect impact forces, but rather act on human tissue through the motion of mutual impact.

[0105] It should be noted that the structure of the first transmission member 163 shown in the subsequent embodiments is also applicable to the transmission connection structure between the second push-pull member 314 and the second collision member 130; for the sake of simplicity, the following description will only focus on the transmission connection between the first push-pull member 312 and the first collision member 120.

[0106] Example 2

[0107] like Figure 14 As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, a closed guide groove 1231 is provided on the first colliding member 120, and the closed guide groove 1231 is in sliding engagement with the second pin 332. The principle is the same as in Embodiment 1, and will not be repeated here.

[0108] Example 3

[0109] like Figure 15 , Figure 16 As shown, in this embodiment, both ends of the first transmission member 163 are slotted structures, that is, the force-applying part 166 and the force-transmitting part 167 of the first transmission member 163 are the first slide groove and the second slide groove, respectively. The front end of the first push-pull member 312 is provided with a fifth pin 335, which slides with the first slide groove. A second pin 332 is provided on the first collision member 120, which cooperates with the second slide groove.

[0110] Example 4

[0111] like Figure 17 As shown, the difference between this embodiment and embodiment three is that in this embodiment, the first push-pull member 312 and the first transmission member 163 are directly connected by a hinge. The first push-pull member 312 can be made of an elastic guide wire. When it is pushed and pulled in the axial direction, it can adapt to the slight lateral swing of the first transmission member 163 due to its elastic structure. Compared with embodiment three, the structure of this embodiment is simpler.

[0112] Example 5

[0113] like Figure 18As shown, in this embodiment, the first transmission member 163 includes two transmission links 168, which are hinged together. The rotation hole 165 of the first transmission link 168 is hinged to the first rotating part 161, the other rotation hole 165 is hinged to the first push-pull member 312, and the rotation hole 165 of the second transmission link 168 is hinged to the second pin 332. Figure 18 The first transmission component 163 shown realizes the transmission connection between the first push-pull component 312 and the first collision component 120. Other components in this embodiment are not shown, and their principles can be referred to in Embodiment 1, which will not be repeated here.

[0114] It should be noted that: Figure 18 The structure of the first transmission member 163 shown can also be applied to the transmission connection structure of the second push-pull member 314 and the second collision member 130. Please refer to Embodiment Six below for the structure of the second push-pull member 314 and the second collision member 130.

[0115] Example 6

[0116] like Figure 19 As shown, in this embodiment, the first transmission member 163 adopts an "L"-shaped structure, and its force-applying part 166 is a rotating hole 165. The first push-pull member 312 and the first transmission member 163 are directly connected by a hinge. The first push-pull member 312 can be an elastic guide wire. When it is pushed and pulled axially, it can adapt to the slight lateral swing of the first transmission member 163 due to its elastic structure. The force-transmitting part 167 of the first transmission member 163 can be a non-closed slot.

[0117] Example 7

[0118] like Figure 20 As shown, in this embodiment, the first transmission component 163 adopts a straight rod structure. The only difference in this embodiment is the shape of the first transmission component 163. Its principle is similar to that of embodiment four.

[0119] Example 8

[0120] like Figure 21 , Figure 22 As shown, in this embodiment, the second collision member 130 also adopts a sliding structure similar to that of the first collision member 120, that is: a third linear guide portion 112 is provided on the seat 110, and a fourth linear guide portion 131 is provided on the second collision member 130. The second collision member 130 is movably installed on the seat 110 and slides in cooperation with the third linear guide portion 112 and the fourth linear guide portion 131.

[0121] Correspondingly:

[0122] A fourth guide cavity 214 is also provided within the guide tube 210. A second conduit 217 is provided within the fourth guide cavity 214, and a second push-pull member 314 is provided within the second conduit 217. The second push-pull member 314 is controlled by a fourth operating member 540. A second rotating part 162 is provided on the seat 110, and a second transmission member 164 is movably mounted on the second rotating part 162. The second transmission member 164 is provided with a force-applying part 166 and a force-transmitting part 167. The force-applying part 166 of the second transmission member 164 is in transmission cooperation with the second push-pull member 314 through a sixth pin 336, and the force-transmitting part 167 cooperates with the second collision member 130. The second push-pull member 314 drives the second collision member 130 to produce a translational movement.

[0123] In this embodiment, the force-applying part 166 is a first sliding groove, the force-transmitting part 167 is a second sliding groove, the front end of the second push-pull member 314 is slidably engaged with the first sliding groove, the second rotating part 162 is a third pin provided on the seat 110, and a fourth pin 334 is provided on the second collision member 130, which is slidably engaged with the second sliding groove.

[0124] Similarly, in order to reduce the lateral swing of the first push-pull member 312 and the second push-pull member 314, two limiting members 340 are provided on the seat 110 to limit the first push-pull member 312 and the second push-pull member 314 respectively.

[0125] In this embodiment, a first linear guide portion 111 and a third linear guide portion 112 need to be provided on the seat 110. Preferably, the first linear guide portion 111 and the third linear guide portion 112 can be arranged vertically overlapping each other. In this embodiment, the third linear guide portion 112 is located above the first linear guide portion 111, and the longitudinal length of the third linear guide portion 112 is less than the longitudinal length of the first linear guide portion 111. During sewing, this ensures that the sewn piece 600 has a longer translational distance. The second pair... The translation of the impactor 130 is only auxiliary; at the same time, a partition 114 is provided between the first linear guide 111 and the third linear guide 112. The partition 114 can prevent the first pair of impactors 120 and the second pair of impactors 130 from interfering with each other, and can also provide support for the second pair of impactors 130; during suturing, in order to limit the translation position of the first pair of impactors 120 and the second pair of impactors 130 and avoid excessive displacement that could damage human tissue, a baffle 115 is provided on the inner side of the third linear guide 112.

[0126] Example 9

[0127] like Figure 23 , Figure 24 and Figure 25As shown, in this embodiment, the position where the force transmission part 167 of the first transmission member 163 cooperates with the first collision member 120 is close to the second linear guide part 121 in the height direction. Preferably, the force application part 166 is a second sliding groove. A second pin 332 is provided on the first collision member 120. The second pin 332 is flush with the second linear guide part 121 in the height direction. When the first collision member 120 is pushed to translate by the force application part 166, the bending moment can be reduced, and the translation of the first collision member 120 can be made smoother. To facilitate the setting of the second pin 332, in this embodiment, the first linear guide part 111 is located on two opposite outer surfaces of the seat 110, and the second linear guide part 121 is located on two opposite inner surfaces of the first collision member 120.

[0128] It should be noted that, in various embodiments of this application, in order to realize the transmission connection structure between the first push-pull member 310 and the first collision member 120, various structures of the first transmission member 163, the connection and cooperation structure between the first transmission member 163 and the first push-pull member 310, and the connection and cooperation structure between the first transmission member 163 and the first collision member 120 can be combined in different ways according to each embodiment; similarly, the connection and transmission structure between the second push-pull member 320 and the second collision member 130 can also be combined in different ways.

[0129] The purpose of the above embodiments is to reproduce and derive the technical solution of the present invention by way of example, and to fully describe the technical solution, purpose and effect of the present invention. The purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosure of the present invention, and not to limit the scope of protection of the present invention.

[0130] The above embodiments are not an exhaustive list based on the present invention, and there may be many other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
