Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices for endoscopic minimally invasive surgery, in particular to a simple closure clip release device and a suturing device. BACKGROUND

[0002] Soft endoscopic gastrointestinal tissue defect / wound closure technology is an important and commonly used technology. Existing technologies mainly include endoscopic clip closure technology and nylon rope / suture combined endoscopic clip purse string suture technology. These technologies are reliable and have low medical cost, and are popular and widely used. The existing endoscopic clip structure used under soft endoscopy includes a clip closing and locking two-part structure, which makes the endoscopic clip have a certain length space to arrange the two-part structure. The above structural characteristics make the endoscopic clip structure more complex and require more operating space; especially for the purse string suture technology, due to the certain height of the endoscopic clip, the endoscopic clip is prone to fall during the purse string suture process, which hinders the closing of the endoscopic clip, greatly affecting the operation efficiency, and even leading to operation failure.

[0069] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0070] For ease of understanding, the following will be based on... Figures 1 to 22 The stitcher shown illustrates the specific structure of the simple closure clamp release device.

[0071] like Figures 1 to 22 As shown, the simplified closure clamp release device 500 for releasing the closure clamp 200 provided in the first aspect of this application includes: a base 10, a mounting shell 20, a push clamp plate 30, and a control component 40.

[0072] The base 10 is configured to connect with the endoscope 100. Specifically, the base 10 is provided with a mounting channel 11, into which the endoscope 100 is inserted so that the base 10 is mounted on the endoscope 100.

[0073] The mounting shell 20 is disposed on the base 10, and the mounting shell 20 has an installation space and a clamping outlet. A one-way snap-fit ​​structure 21 is provided within the installation space, configured to engage unidirectionally with the closing clamp 200, allowing the closing clamp 200 to move unidirectionally. Specifically, the clamping outlet communicates with the installation space, which has a bottom wall and side walls arranged circumferentially along the bottom wall. The one-way snap-fit ​​structure 21 is provided on the side walls. The one-way snap-fit ​​structure 21 is a snap-fit ​​piece. In a specific embodiment of this application, the mounting shell 20 includes: an outer shell 25 and a cover plate 26. The outer shell 25 includes a bottom plate and a side plate. A push clamping plate 30 is disposed on the bottom plate, and the one-way snap-fit ​​structure 21 is disposed on the side plate. A first connecting structure 251 is provided on the side plate. A cover plate 26 is fitted onto the outer casing 25, forming an installation space. The cover plate 26 has a second connecting structure 261 that mates with the first connecting structure 251. One of the first connecting structure 251 and the second connecting structure 261 is a connecting groove, and the other is a guide rail. Specifically, the first connecting structure 251 can be either a connecting groove or a guide rail, and similarly, the second connecting structure 261 can also be either a connecting groove or a guide rail. Those skilled in the art can choose the configuration of the connecting groove and the guide rail as needed.

[0074] The push clamping plate 30 is located in the installation space and is arranged on the bottom wall of the installation shell 20. The push clamping plate 30 can move towards or away from the ejection opening. The push clamping plate 30 is provided with at least one mounting position 31 configured to fix the closure clip 200. In an embodiment of the present application, the mounting position 31 is provided with elastic limiting structures configured to cooperate with the closure clip 200 to enable the push clamping plate 30 to drive the closure clip 200 to move. The elastic limiting structures include a plurality of elastic pieces 311. The closure clip 200 is fixed to the push clamping plate 30 through the plurality of elastic pieces 311.

[0075] The control assembly 40 is connected with the push clamping plate 30. The control assembly 40 is configured to control the movement of the push clamping plate 30 relative to the installation shell 20.

[0076] The simple closure clip release device 500 provided by the present application fixes the closure clip 200 to the push clamping plate 30 through the mounting position 31 and controls the movement of the push clamping plate 30 relative to the installation shell 20 through the control assembly 40, so that the closure clip 200 arranged on the push clamping plate 30 is pushed out of the ejection opening and into the human tissue incision 400. During the movement of the push clamping plate 30, the closure clip 200 on the push clamping plate 30 can only move towards the ejection opening due to the limitation of the one-way clamping structure 21. During the above suturing process, a plurality of closure clips 200 can be installed and released one by one, thereby improving the operation efficiency.

[0077] In addition, the simple closure clip release device 500 has fewer components and a simple structure, and the components are not connected in a complex manner. On the one hand, the layout of the product is more concise, the occupied space is small, and the product is easy to install and maintain. At the same time, the product is suitable for more scene applications, especially in narrow operation spaces. On the other hand, the complexity and failure rate of the product are reduced, and the reliability and stability of the system are improved.

[0078] As shown in Figures 1 to 22 the specific operation process of the simple closure clip release device 500 is as follows:

[0079] Firstly, the closure clip 200 is installed on the mounting position 31 of the push clamping plate 30, and then the seat body 10 is connected with the front end of the endoscope 100. After that, the simple closure clip release device 500 is inserted into the human body together with the endoscope 100 to the operation site.

[0080] Secondly, the human tissue to be sutured is clamped or anchored by the existing endoscopic forceps or other endoscopic instruments, and then the human tissue is pulled to the ejection opening.

[0081] Thirdly, the pusher 30 is controlled by the control assembly 40 to move towards the ejection port until the partial closure clip 200 is ejected from the ejection port, and then the closure clip 200 is changed from the open state to the suture state to suture the human tissue wound 400 (after the partial closure clip 200 is separated from the pusher 30, the partial closure clip 200 is changed from the open state to the suture state under the action of the elasticity of the partial closure clip 200; or, under the action of the two clamping arms, the partial closure clip 200 is deformed by extrusion, and is changed from the open state to the suture state).

[0082] Fourthly, the pusher 30 is controlled by the control assembly 40 to move away from the ejection port, and in this process, the partial closure clip 200 is ejected from the mounting shell 20 due to the action of the one-way clamping structure 21, and at the same time, the next partial closure clip 200 is relatively moved forward on the pusher 30, so that the next partial closure clip 200 enters the mounting position 31 at the front end of the pusher 30, and prepares for the second suture.

[0083] As shown in Figures 1 to 7 , Figures 9 to 12 , in an embodiment of the present application, the bottom wall is provided with a first limiting structure 22, and the pusher 30 is provided with a second limiting structure 32 matched with the first limiting structure 22.

[0084] One of the first limiting structure 22 and the second limiting structure 32 is a limiting groove, and the other is a sliding piece. The limiting groove extends along the moving direction of the pusher 30, and the sliding piece can slide in the limiting groove. Specifically, the first limiting structure 22 can be a limiting groove, or can be a sliding piece. Correspondingly, the second limiting structure 22 can be a sliding piece, or can be a limiting groove. Those skilled in the art can select the setting of the limiting groove and the sliding piece according to the needs.

[0085] The cooperation of the sliding piece and the limiting groove limits the moving distance of the pusher 30, so that the moving distance of the pusher 30 is just enough to push out one partial closure clip from the ejection port, which avoids the situation that the pusher 30 moves too much and the partial closure clip 200 cannot effectively suture the human tissue wound 400, thereby reducing the probability of misoperation and ensuring the stability and reliability of the product.

[0086] As shown in Figures 1 to 7 , Figures 9 to 12 , in an embodiment of the present application, the mounting shell 20 is provided with a suture groove 23, the suture groove 23 is communicated with the ejection port, and the suture groove 23 is configured to accommodate the human tissue wound 400.

[0087] The pusher 30 is provided with an avoiding space 33 matched with the shape of the suture groove 23.

[0088] The suture groove 23 provides a suture space for human tissue. During the suture process, the human tissue only needs to be pulled into the suture space, and the closure clip 200 sutures the human tissue in the suture groove 23. The operator does not need to ensure that the closure clip 200 is aligned with the human tissue to be sutured in real time, thereby reducing the suture difficulty, ensuring the suture efficiency, and ensuring the suture precision of the closure clip 200 to the human tissue.

[0089] Several embodiments of the control assembly 40 will be described in detail below with reference to the accompanying drawings.

[0090] Embodiment one

[0091] As shown in Figures 1 to 7 , Figures 9 to 12 The control assembly 40 includes a first control rope 41, a fixed pulley 42, and a second control rope 43.

[0092] The first control rope 41 is connected to the push clip plate 30, and is configured to control the push clip plate 30 to move away from the ejection opening.

[0093] The fixed pulley 42 is arranged on the bottom wall or the seat body 10, and can rotate relative to the bottom wall or the seat body 10.

[0094] The second control rope 43 is connected to the push clip plate 30 after passing through the fixed pulley 42, and is configured to control the push clip plate 30 to move towards the ejection opening. When the fixed pulley 42 is arranged on the seat body 10, the seat body 10 is provided with a mounting groove 12 and a wire groove 13, the fixed pulley 42 is at least partially arranged in the mounting groove 12, the second control rope 43 is located in the wire groove 13, and part of the fixed pulley 42 passes through the bottom wall to ensure that the second control rope 43 is connected to the push clip plate 30.

[0095] The operation process of the above control assembly 40 is as follows:

[0096] The second control rope 43 is pulled to drive the push clip plate 30 to move towards the ejection opening until part of the closure clip 200 passes through the ejection opening, and then the closure clip 200 changes from an open state to a suture state to suture the human tissue wound 400 (after the closure clip 200 is separated from the push clip plate 30, the closure clip 200 changes from the open state to the suture state under the action of its own elasticity; or, under the action of the two clamping arms, the closure clip 200 is deformed by being pressed to change from the open state to the suture state); after the suture is completed, the first control rope 41 is pulled to drive the push clip plate 30 to move away from the ejection opening, so that the next closure clip 200 moves on the push clip plate 30 until the next closure clip 200 enters the mounting position 31 at the front end of the push clip plate 30 to prepare for the second suture.

[0097] The structure of the aforementioned control component 40 allows the movement of the push clamp 30 to be achieved by dragging the first control cable 41 and the second control cable 43. The structure is simple. In addition, the forward and backward movement of the push clamp 30 is driven by the two control cables, ensuring that there is sufficient driving force to drive the push clamp 30.

[0098] Example 2

[0099] like Figures 19 to 22 As shown, in one embodiment of this application, the control component 40 includes a push-pull cable 44 and an elastic element 45, the elastic element 45 being disposed between the push clamp plate 30 and the support surface 70. The support surface 70 may be disposed in the mounting housing 20, or a separate structure with a support surface 70 may be provided.

[0100] The push-pull cable 44 is configured to control the push clamp 30 to move toward or away from the outlet.

[0101] Pushing the push-pull cable 44 causes the push clamp plate 30 to move towards the exit clamp opening until part of the closing clamp 200 passes through the exit clamp opening. During this process, the elastic element 45 releases its elastic force to assist the movement of the push clamp plate 30, and then the closing clamp 200 changes from the open state to the suturing state to suture the human tissue wound 400 (after the closing clamp 200 separates from the push clamp plate 30, the closing clamp 200 changes from the open state to the suturing state under its own elastic force; or, under the action of the two clamping arms, the closing clamp 200 is squeezed and deformed, changing from the open state to the suturing state). After suturing is completed, dragging the push-pull cable 44 causes the push clamp plate 30 to move away from the exit clamp opening, so that the next closing clamp 200 moves on the push clamp plate 30 until the next closing clamp 200 enters the mounting position 31 at the front end of the push clamp plate 30, preparing for the second suturing. During this process, the elastic element 45 stores force.

[0102] The structure of the aforementioned control component 40 allows the push clamp 30 to move by dragging or pushing / pulling the push-pull cable 44. The structure is simple, reducing the complexity and failure rate of the product, making the product layout more concise, and improving the reliability and stability of the system.

[0103] The following describes several embodiments of controlling the closing clip 200 to change from an open state to a sewn state, with reference to the accompanying drawings.

[0104] Example 1

[0105] like Figures 1 to 7 , Figures 9 to 12As shown, in one embodiment of this application, a third limiting structure 24 is provided on the bottom wall of the mounting shell 20 and / or the push clamp 30; the third limiting structure 24 is configured to cooperate with a fourth limiting structure 201 on the closing clamp 200. The third limiting structure 24 includes symmetrically arranged guide grooves or symmetrically arranged slide rails, and the guide grooves or slide rails extend along the moving direction of the push clamp 30.

[0106] The elastic closure clip 200 is installed on the mounting position 31, and the fourth limiting structure cooperates with the third limiting structure 24 so that the closure clip 200 is opened and in the open state. When part of the closure clip 200 is pushed out of the clip opening, the push plate 30 is controlled to move away from the clip opening. Due to the limiting effect of the one-way snap-fit ​​structure 21, the closure clip 200 cannot move with the push plate 30, so that the closure clip 200 and the push plate 30 gradually separate. When the closure clip 200 is completely separated from the push plate 30 (at the same time, the fourth limiting structure and the third limiting structure 24 separate), the closure clip 200 closes under the elastic action and changes from the open state to the suture state, and the closure clip 200 is fixed on the human tissue.

[0107] Example 2

[0108] like Figures 14 to 17 As shown, in one embodiment of this application, the simple closing clamp release device 500 further includes: two clamping arms 50 and a push-pull member 60.

[0109] Two clamping arms 50 are hinged together and mounted on the mounting housing 20. The two clamping arms 50 are configured to control the closing clamp 200 to change from an open state to a sewn state.

[0110] The push-pull member 60 is connected to two clamping arms 50, and the push-pull member 60 is configured to control the rotation of the two clamping arms 50 relative to each other.

[0111] Specifically, the clamping arm 50 includes a connecting end and a clamping end that are arranged opposite to each other. The clamping end cooperates with the closing clamp 200, and the connecting end is connected to the push-pull member 60.

[0112] After the partial closing clip 200 is pushed out of the clamping opening, the partial closing clip 200 is located between the clamping ends of the two clamping arms 50. Then, the push-pull member 60 is dragged, and the push-pull member 60 drives the clamping arms 50 to rotate relative to the mounting shell 20, so that the clamping ends of the two clamping arms 50 are closed. The two clamping arms 50 deform the closing clip 200, so that the closing clip 200 changes from the open state to the suturing state, and the human tissue is sutured.

[0113] The structure for changing the state of the closing clamp 200 can change the closing clamp 200 from the open state to the suturing state by pushing and pulling the pushing and pulling piece 60 to close the two clamping arms 50, and has simple structure, reduces the complexity of the product, and does not need to be made of special elastic material to reduce the manufacturing difficulty and production cost of the product.

[0114] In an embodiment of the present application, the clamping arm 50 is provided with a clamping groove 51, and the two clamping grooves 51 form a clamping space, which is in communication with the mounting space through the clamping outlet, and is configured to accommodate the closing clamp 200.

[0115] Since the closing clamp 200 needs to be deformed by being squeezed by the clamping arm 50 to suture the human tissue, after the clamping ends of the two clamping arms 50 are closed, the suturing groove 23 between the two clamping arms 50 forms an accommodation space for accommodating the deformed closing clamp 200, thereby ensuring the shape of the deformed closing clamp 200 and avoiding the problem of poor suturing effect caused by excessive deformation of the closing clamp 200, i.e., ensuring the reliability of the closing clamp 200.

[0116] In an embodiment of the present application, the clamping groove 51 is provided with an anti-falling limiting structure on the groove wall, which is configured to cooperate with the closing clamp 200.

[0117] The anti-falling limiting structure, on the one hand, prevents the closing clamp 200 from falling out of the clamping groove 51, avoids the situation that the closing clamp 200 needs to be reinstalled due to falling out, thereby ensuring the suturing effect and efficiency of the product, and on the other hand, plays a limiting role on the closing clamp 200, avoids the situation that the closing clamp 200 moves or shakes during deformation, i.e., ensures the reliability of the deformation of the closing clamp 200.

[0118] Embodiment Three

[0119] In an embodiment of the present application, the bottom wall of the mounting shell 20 and / or the pushing and clamping plate 30 is provided with a third limiting structure 24; the third limiting structure 24 is configured to cooperate with a fourth limiting structure 201 on the closing clamp 200. The third limiting structure 24 is two side surfaces provided on the pushing and clamping plate 30 along the moving direction thereof.

[0120] The elastic closing clip 200 is installed on the installation site 31, and the fourth limiting structure is clamped on the side of the push clip plate 30, so that the closing clip 200 is opened in the open state; when part of the closing clip 200 is pushed out of the clip opening, the push clip plate 30 is controlled to move away from the clip opening, and the closing clip 200 cannot move together with the push clip plate 30 due to the limiting effect of the one-way clamping structure 21, so that the closing clip 200 gradually separates from the push clip plate 30, and when the closing clip 200 is completely separated from the push clip plate 30 (at the same time, the fourth limiting structure is separated from the third limiting structure 24), the closing clip 200 is closed from the open state to the suturing state under the elastic action, and the closing clip 200 is fixed on the human tissue.

[0121] Those skilled in the art should understand that the scheme of embodiment one and the scheme in embodiment three can exist at the same time, specifically, the third limiting structure can be arranged on the bottom wall of the installation shell 20, and the two sides of the push clip plate 30 arranged along the moving direction of the push clip plate 30 can also be the third limiting structure, so that the closing clip 200 is in the open state. The above arrangement can make the push clip plate 30 move smoothly, and the resistance received is smaller.

[0122] As shown in Figures 1 to 22 , the second aspect of the application provides a suturing device, which comprises the simple closing clip releasing device 500 and the closing clip 200.

[0123] The closing clip 200 is arranged on the installation site 31 of the push clip plate 30 of the simple closing clip releasing device 500, and the closing clip 200 is provided with a matching structure matched with the one-way clamping structure 21 of the installation space of the simple closing clip releasing device 500.

[0124] The application provides a suturing device, which can install multiple closing clips 200 and realize one-by-one multiple release, thereby improving the operation efficiency; the suturing is realized through self-elasticity or extrusion and puncture deformation, and the structure is simple and small in size. In the process of purse-string suture, there is no situation that the closing clip is down and hinders the suture, thereby improving the success rate and efficiency of suture.

[0125] As shown in Figure 4b and Figure 5 , in one embodiment of the application, the closing clip 200 is provided with a fourth limiting structure matching part 201, and the fourth limiting structure comprises two protrusions arranged symmetrically.

[0126] The two protrusions are respectively pressed on the two sides of the push clip plate 30 or inserted into the guide groove on the bottom wall of the installation shell 20 or the guide groove of the push clip plate 30.

[0127] In one embodiment of the application, the closing clip 200 is provided with a fourth limiting structure matching part 201, and the fourth limiting structure comprises two limiting grooves arranged symmetrically.

[0128] The two limiting grooves are respectively matched with the slide rails on the bottom wall of the mounting shell 20 or the slide rails on the push clamping plate 30.

[0129] The fourth limiting structure is simple in structure, and facilitates the installation and release of the closure clamp in the open state.

[0130] As shown in Figures 1 to 22 In one embodiment of the present application, two puncture parts 202 are symmetrically arranged on the closure clamp 200 and extend towards each other.

[0131] The puncture part 202 can be inserted into the human tissue, so that the closure clamp 200 is more firmly fixed on the human tissue, and the reliability of the closure clamp 200 in suturing is improved.

[0132] As shown in Figure 18 In one embodiment of the present application, the closure clamp 200 is provided with a barb limiting part 204.

[0133] When the closure clamp 200 is fixed on the human tissue, the barb limiting part 204 and the puncture part 202 penetrate into the human tissue at the same time, and the barb limiting part 204 can further stably fix the closure clamp 200 on the human tissue, thereby reducing the probability of the closure clamp 200 slipping off and effectively suturing the human tissue, especially for some parts with relatively large activity or wounds that need to bear relatively large tension.

[0134] As shown in Figures 9 to 13 In one embodiment of the present application, the suturing device further comprises a suture 300, and the suture 300 is connected with the closure clamp 200.

[0135] When the wound 400 on the human tissue is large, a plurality of closure clamps 200 are fixed on the human tissue along the circumference of the wound 400, and then the suture 300 is pulled, so that the suture 300 gathers the plurality of closure clamps 200, and the plurality of closure clamps 200 are gradually gathered to suture the wound 400.

[0136] As shown in Figures 9 to 13 In one embodiment of the present application, the closure clamp 200 is provided with a wire passing hole 203 for the suture 300 to pass through.

[0137] The wire passing hole 203 facilitates the connection between the suture 300 and the closure clamp 200, and in addition, the wire passing hole 203 can make the suture 300 be located at a specific position of the closure clamp 200, so that the suture 300 can effectively gather the plurality of closure clamps 200 in the process of pulling the suture 300, and the quality of suturing is higher.
