Description

Technical Field

[0001] This invention belongs to the field of medical devices, specifically relating to a staple suture device, a staple suture mechanism, a staple suture apparatus, and an endoscopic suture 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

[0101] Example 1

[0102] like Figures 1 to 15 As shown, the staple suture device 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, and a staple suturer.

[0103] The guide tube 210 has a first guide cavity 211 and a third guide cavity 215. A first push-pull member 310 is disposed in the first guide cavity 211. In this embodiment, the first push-pull member 310 is made of a guide steel wire with a certain degree of elasticity and rigidity. An endoscope 350 is disposed in the third guide cavity 215, and a fourth guide cavity 351 is disposed in the endoscope 350. A control cable 530 is disposed in the fourth guide 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 310 to bend adaptively in a bent state, effectively transmitting the pushing and pulling force.

[0104] The tip of the endoscope 350 is inserted into the fixing hole 113 on the base 110 of the stapler, and can be connected to the base 110 of the stapler 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 base 110 of the stapler, and is controlled by the control cable 530.

[0105] The rear end of the nail-shaped suture device is provided with a first operating member 510 and a second operating member 520. The first operating member 510 can push and pull the first push-pull member 310 to control the nail-shaped suture device (the specific structure and principle of the nail-shaped suture device will be described below). The second operating member 520 acts on the control cable 530 to control the clamp 410.

[0106] The following is a detailed description of the stapled stapler:

[0107] Please also focus on combining Figures 3 to 7 As shown, the staple-shaped stapler includes a base 110 and a first counteractor 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 counteractor 120. The first counteractor 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 counteractor 130 is also provided on the base 110. The first counteractor 120 and the second counteractor 130 are opposite to each other. One of the opposite sides of the first counteractor 120 and the second counteractor 130 is provided with a staple mounting position 125 for mounting the staple 600, and the other opposite side is provided with a staple stitching portion 132.

[0108] During suturing, the staple-shaped stapler is placed at the site of the human tissue to be sutured, with the tissue positioned between the first pair of impactors 120 and the second pair of impactors 130. The first pair of impactors 120 translate towards each other under external force. The staple 600, under the impact of the first and second pair of impactors 120 and the second pair of impactors 130, penetrates the human tissue to be sutured, bends, and then sutures the tissue. This staple-shaped stapler 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 embodiment, since the first pair of impactors 120 is guided by the first linear guide 111 and the second linear guide 121, and moves by translation during movement, it reduces tissue displacement, resulting in high suturing precision and reliability. The effect is similar to that of open abdominal surgery and rigid endoscopy, where metal staples quickly and firmly close the defect, ensuring the effectiveness of the suturing.

[0109] 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 base 110. This can be achieved by using a combination of linear guide grooves and linear guide rails, or by using linear guide rods 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 linear guide portion 111 is located on two opposite outer surfaces of the base 110. The first collider 120 includes an end plate 123 and side arms 124 located on both sides of the end plate. The second linear guide portion 121 is disposed on the outer surfaces of the two side arms 124.

[0110] The translation of the first collision member 120 is controlled by the first push-pull member 310. In this embodiment, a first rotating part 161 is provided on the seat 110, and a first transmission member 163 is movably installed on the first rotating part 161. The first transmission member 163 adopts an "L"-shaped rod with closed slots at both ends. A force-applying part 166 (i.e., a first sliding groove) is provided at the rear end of the first transmission member 163, and a force-transmitting part 167 (i.e., a second sliding groove) 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 installed on the seat 110 through the first rotating part 161. A fifth pin 335 is provided at the front end of the first push-pull member 310. The fifth pin 335 slides with the first sliding groove. A second pin 332 is provided on the first collision member 120. The second pin 332 slides with the second sliding groove. In this embodiment, by operating the first operating member 510 and driving the first transmission member 163 to rotate through the first push-pull member 310, the longitudinal translational movement of the first push-pull member 310 along the direction of the endoscope 350 is transformed into the lateral translational movement of the first collision member 120, so that the suture staple 600 can accurately puncture the tissue to be sutured and realize the suturing of human tissue.

[0111] To reduce the swaying of the first push-pull member 310 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 213 is limited by the limiting hole 341, which reduces the lateral swaying of the first push-pull member 310.

[0112] 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.

[0113] In this embodiment, the guide tube 210 is manufactured separately and used in conjunction with the endoscope 350. Alternatively, a corresponding first guide cavity 211 can be provided within the endoscope 350. It is understood that the guide tube 210 and the endoscope 350 can also be fixed together using straps or other structures. Depending on the application scenario, the guide tube 210 may also be used directly with a stapler to perform suturing without needing to be used with the endoscope 350.

[0114] It should be noted that:

[0115] In this invention, when the first collider 120 is translated by the first operating member 510, 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 staples 600. All of these are within the scope of protection of this application.

[0116] Please focus on combining Figure 14 , Figure 15 As shown, in this embodiment, the suture staple 600 adopts an approximate "∩" shape, which includes a staple plate 620 and two staple bodies 610 installed on one side of the staple plate 620. The tips 611 of the two staple bodies 610 are both facing forward. During suturing, the first collision member 120 drives the suture staple 600 to collide with the second collision member 130, and causes the staple body 610 of the suture staple 600 to bend. After bending, the tips 611 return and face the staple plate 620. The staple plate 620 can block the tip 611, preventing the tip 611 from causing further damage to human tissue. To facilitate the installation of the suture staple 600 and prevent it from shifting, tilting, or falling off during the sewing process, a staple fixing member 140 is provided at the staple mounting position 125. The staple fixing member 140 is elastic and slightly smaller than the size of the suture staple 600. Furthermore, the staple fixing member 140 is C-shaped, including a connecting edge 141 and two limiting edges 142. The two limiting edges 142 are located at both ends of the connecting edge 141 and are integrally formed. The two sides of the suture staple 600 are limited by the two limiting edges 142 to prevent it from falling off. After sewing, due to the elasticity of the two limiting edges 142, the staple plate 620 can break through the limiting edges 142 under external force, thereby separating the suture staple 600 from the staple fixing member 140.

[0117] Please focus on combining Figures 8 to 13 As shown, the steps for suturing human tissue are as follows:

[0118] like Figure 8 , Figure 9 As shown, by operating the first operating member 510, the first colliding member 120 is positioned flush with the longitudinal direction of the seat body 110. This state is the insertion state of the nail-shaped suture device. The lateral dimension of the nail-shaped suture device is small to facilitate its insertion and avoid the nail-shaped suture device from abrading the mucosal tissue of the digestive tract lumen.

[0119] like Figure 10 , Figure 11As shown, by operating the first operating member 510, the first collision member 120 is positioned on the outside, and the suture staple 600 is placed flat. This state is the open state of the staple-shaped suture device. The lateral dimension of the staple-shaped suture device is relatively large, 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.

[0120] like Figure 12 , Figure 13 As shown, this state is the suturing state of the stapled stapler. By operating the first operating member 510, the first collision member 120 is quickly moved inward and the staple 600 is driven to collide with the second collision member 130. During the translation process, the staple 600 penetrates the tissue to be sutured. Then, at the staple suture part 132, the staple tip 611 of the staple 600 is bent to achieve the effect of suturing human tissue.

[0121] The aforementioned three states are not necessarily the states in which the nail-shaped sewing device described in this embodiment is used. For example, in the insertion state, the first collision member 120 can be located slightly inside the seat 110.

[0122] like Figure 4 As shown, during suturing, in order to ensure the effective bending of the nail tip 611 of the suture staple 600, an inward concave arc 133 and an outward convex arc 134 are provided on the inner side of the second collision member 130, which can guide the bending direction of the nail tip 611. Preferably, there are two inward concave arcs 133, which are located on both sides of the outward convex arc 134. The two inward concave arcs 133 guide the nail tips 611 of the two nail bodies 610 of the suture staple 600 to bend towards the center.

[0123] Example 2

[0124] like Figure 16 As shown, the difference between this embodiment and embodiment one is that the force-applying part 166 of the first transmission member 163 does not have a first sliding groove, but is directly hinged to the front end of the first push-pull member 310 through the fifth pin 335. When the first transmission member 163 rotates, the elasticity of the first push-pull member 310 realizes the lateral swing of its front end. This structure is simpler and easier to process than embodiment one.

[0125] Example 3

[0126] like Figure 17As 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 310, and the rotation hole 165 of the second transmission link 168 is hinged to the second pin 332. Figure 17 The first transmission component 163 shown realizes the transmission connection between the first push-pull component 310 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.

[0127] It should be noted that: Figure 17 The structure of the first transmission member 163 shown can also be applied to the transmission connection structure of the second push-pull member 320 and the second collision member 130. Please refer to Embodiment Nine below for the structure of the second push-pull member 320 and the second collision member 130.

[0128] 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 320 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 310 and the first collision member 120.

[0129] Example 4

[0130] like Figure 18 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 310 and the first transmission member 163 are directly connected by a hinge. The first push-pull member 310 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.

[0131] Example 5

[0132] like Figure 19 As shown, in this embodiment, the first transmission component 163 adopts a straight rod structure, and its principle is similar to that of Embodiment 4.

[0133] Examples 2, 3, 4, and 5 describe the transmission structure or relationship between the first push-pull member 310 and the first collision member 120 from the perspective of the first transmission member 163. Subsequent examples will be described from the perspective of the first collision member 120.

[0134] Example 6

[0135] like Figures 20 to 26As shown, the difference between this embodiment and Embodiment 1 is that the structure of the suture staple 600 used in this embodiment is different. In this embodiment, the suture staple 600 includes a clamp 630, which is installed on the second collision member 130 and fixed by the staple clamp 140. The staple body 610 of the suture staple 600 is fixed on the staple plate 620. The front part of the staple body 610 has a staple tip 611, and the rear side of the staple tip 611 gradually expands to form a limiting structure. The clamp 630 has two elastic lateral arms 631, which are bent inward to form two elastic locking arms 632. The staple tip 611 faces between the two elastic locking arms 632. When the staple body 610 moves towards the second collision member 130 under the action of the first collision member 120, the staple tip 611 is inserted between the two elastic locking arms 632 and cannot come out, so as to achieve the effect of the suture staple 600 clamping and suturing human tissue. The chuck 630 is not limited to two elastic lateral arms 631; there can also be multiple lateral arms 631. The chuck 630 can also employ other structures that achieve the same effect.

[0136] It should be noted that there can be one or more staples 610. Correspondingly, the structure and size of the clamp 630 are matched with one or more staples 610. Multiple staples 610 can suture a wider range of tissues at one time, which improves the efficiency of suturing.

[0137] It is understood that the structure of the suture staple is not limited to the structure described in Embodiment 1 and this embodiment. The structure of the suture staple can be further modified according to clinical needs and the patient's physical characteristics.

[0138] Another difference in this embodiment is that, in this embodiment, the first transmission member 163 is L-shaped, its force-applying part 166 forms a first sliding groove, its force-transmitting part 167 is a round hole, the second pin 332 is fixed in the round hole, and the first collision member 120 is provided with an open guide groove 1231. The second pin 332 connected to the first transmission member 163 is inserted into the guide groove 1231 and cooperates with the guide groove 1231.

[0139] 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, in subsequent embodiments, 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.

[0140] It should be noted that, in this embodiment, there may be two or more nails 610 mounted on the nail plate 620, and each nail 610 faces the clamp 630 and corresponds to the clamp 630. During sewing, the tips 611 of the two nails 610 are simultaneously engaged in the elastic clamping arms 632 of the clamp 630.

[0141] Example 7

[0142] like Figure 27 As shown, in this embodiment, an open guide hole is provided only on one side of the first colliding member 120. A second pin 332 is provided in the guide hole. To prevent the second pin 332 from coming out, an end cap 3321 is provided at the inner end of the second pin 332 for limiting. Other components in this embodiment are not shown, and their principles can be referred to in other embodiments, which will not be repeated here.

[0143] Example 8

[0144] like Figure 28 , Figure 29 As shown, in this embodiment, the first transmission member 163 is L-shaped, with its force-applying part 166 forming a first sliding groove and its force-transmitting part 167 being a round hole. The second pin 332 is fixed in the round hole. A closed guide groove 1231 is provided on the first collision member 120. The second pin 332, which is connected to the first transmission member 163, is inserted into the guide groove 1231 and cooperates with the guide groove 1231. The principle can be referred to in Embodiment Six, which will not be repeated here.

[0145] In the foregoing embodiments, the suture staple 600 (or its main body) is mounted on the first collision member 120, and the suturing of human tissue is achieved by the translation of the first collision member 120. It can be understood that in the foregoing embodiments, the suture staple 600 (or its main body) can also be mounted on the fixed second collision member 130, and the suture staple tip 611 of the suture staple 600 is subjected to force by the translation of the first collision member 120, thereby achieving the suturing of human tissue.

[0146] Example 9

[0147] like Figures 30 to 34 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.

[0148] Correspondingly:

[0149] A second guide cavity 212 is also provided within the guide cavity tube 210, and a second conduit 214 is provided within the second guide cavity 212. A second push-pull member 320 is provided within the second conduit 214. A second rotating part 162 is provided on the seat body 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 of the second transmission member 164 is in transmission cooperation with the second push-pull member 320 through a sixth pin 336, and the force-transmitting part 167 cooperates with the second collision member 130. The second push-pull member 320 drives the second collision member 130 to produce a translational movement.

[0150] 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 320 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.

[0151] Similarly, in order to reduce the lateral swing of the first push-pull member 310 and the second push-pull member 320, two limiting members 340 are provided on the seat 110 to limit the first push-pull member 310 and the second push-pull member 320 respectively.

[0152] 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 suture staples 600 have 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.

[0153] The three working states of the nail-shaped suture device described in this embodiment are as follows: Figures 32 to 34 The images show the three states of the nail suture during entry, opening, and suturing.

[0154] It is understandable that when both the first collider 120 and the second collider 130 adopt a translational structure, the positions of the nail mounting position 125 and the nail sewing part 132 can be interchanged. That is, the nail mounting position 125 can be set on the second collider 130, while the nail sewing part 132 can be set on the first collider 120.

[0155] Example 10

[0156] like Figures 35 to 45 As shown, in this embodiment, the first colliding member 120 is provided with a staple receiving groove 150 for storing the suture staples 600. The staple receiving groove 150 includes a groove body 152 and an elastic member 155 located below the groove body 152. The groove body 152 includes a staple body 610 receiving portion 153 and a staple plate 620 receiving portion 154. Two mounting holes 151 are provided below the staple plate 620 receiving portion 154. The elastic member 155 is a coil spring or other elastic member with the same effect and is installed in the mounting holes 151.

[0157] During the suturing process, the first suture pin 600 is removed from the pin receiving groove 150 after suturing. The second suture pin 600 moves upward relative to the pin receiving groove 150 under the action of the elastic member 155 for the second suturing, and so on.

[0158] Multiple suture staples 600 can be pre-placed in the staple receiving groove 150. By inserting the staple-shaped suture device described in this embodiment into the human body at one time, multiple human tissue suturings can be performed continuously, reducing the frequency of the staple-shaped suture device repeatedly entering and exiting the human body to install suture staples, thereby improving suturing efficiency and reducing damage to human tissues when the staple-shaped suture device repeatedly enters and exits the human body.

[0159] The staple receiving slot 150 is provided to facilitate the installation of multiple suture staples 600. However, the staple receiving slot 150 is not a necessary structure for installing multiple suture staples 600. If the size of the staple mounting position 125 is sufficient, multiple suture staples 600 can also be installed on the staple mounting position 125.

[0160] Correspondingly, to facilitate the placement of the nail receiving groove 150 into the first collision member 120, a retaining edge 129 is provided on the inner side of the first collision member 120 to prevent the nail receiving groove 150 from falling out. A slot 127 is also provided on the first collision member 120, and a cover plate 128 is provided in the slot 127. After the nail receiving groove 150 is placed into the first collision member 120, the cover plate 128 is inserted into the slot 127 to fix the nail receiving groove 150. During sewing, the nail receiving groove 150 and the first collision member 120 move synchronously. To avoid interference, a nail groove outlet 116 is provided on the base 110.

[0161] In this embodiment, the force transmission part 167 of the first transmission member 163 is positioned to cooperate with the first collision member 120 at a height close to the second linear guide part 121. Preferably, the force transmission part 167 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 transmission part 167, 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.

[0162] 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.

[0163] 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.
