Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device technology, specifically relating to an organ hemostasis suture device and an organ hemostasis suture apparatus. Background Technology
[0002] In surgical procedures, especially minimally invasive surgery (such as laparoscopy and thoracoscopy), organ hemostatic suture devices are commonly used to suture organs. These devices, often simply referred to as surgical staplers or cutting staplers, are mechanical devices that simultaneously perform tissue cutting, vascular closure (hemostasis), and wound closure. They create a reliable B-type or H-type closure on both sides of the tissue by firing two or three rows of staggered titanium alloy or absorbable staples (similar to "staples"), and then cut the tissue in one go using an internal blade.
[0003] The organ hemostatic suture device can push the sutures of the staple row outward one by one, thereby tightening the wound on both sides of the organ and preventing the wound from opening and continuing to bleed.
[0004] However, in the use of existing organ hemostasis suture devices, it is usually necessary to first rotate the suture cartridge 90° to change the orientation of the suture row so that the opening of the suture staples faces forward, or directly set the suture cartridge to be perpendicular to the outer tube and then push the suture staples forward. After the suture cartridge is rotated, it will greatly affect the surgical field of vision and also take up a lot of space. Summary of the Invention

Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0035] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0036] Example 1: Please refer to Figures 1-6 As shown, Embodiment 1 of the present invention provides an organ hemostasis and suturing device 100, which is used to suture and stop bleeding in a patient's organs, thereby tightening the wound on both sides towards the middle to prevent continuous exposure and bleeding. The organ hemostasis and suturing device 100 can be used to stop bleeding and suture organs in open wounds as well as organs in closed wounds. For example, medical personnel can insert the organ hemostasis and suturing device 100 into place using a minimally invasive method.
[0037] Of course, in other embodiments, the organ hemostasis suturing device 100 can not only suture organs, but also non-organs such as skin. The application of the organ hemostasis suturing device 100 can be flexibly selected according to needs.
[0038] The organ hemostasis and suturing device 100 mainly consists of an organ hemostasis and suturing device 10 and a staple row 20, with the staple row 20 installed inside the organ hemostasis and suturing device 10.
[0039] It should be noted that the organ hemostasis suture device 10 can be produced, manufactured, and sold independently, and does not depend on the staple row 20. The staple row 20 can be pre-installed in the organ hemostasis suture device 10 during the production process, or the staple row 20 can be installed in the organ hemostasis suture device 10 during subsequent use.
[0040] The staple row 20 includes several staples. The number of staples can be set as needed, such as one, two, ten, twenty, etc. Adjacent staples are connected, and the connection method can refer to the staple row 20 of the stapler in the prior art.
[0041] The material of the suture staples is not limited, such as metal, non-metal, absorbable, and non-absorbable materials, but it must be made of medical-grade material.
[0042] The suture staple includes a base staple and two side staples. The two side staples are located at both ends of the base staple. The side staples can be perpendicular to the base staple or not, and the two side staples can be parallel or not. In this embodiment, it is preferable that the side staples are perpendicular to the base staple and the two side staples are parallel to each other.
[0043] The sutures in the suture row 20 are arranged at an angle, meaning that the length direction of the suture row 20 forms an angle with the opening direction of the sutures. The length direction of the suture row 20 refers to the arrangement direction of the multiple sutures. Assuming that the side sutures are perpendicular to the bottom sutures, the extension direction of the side sutures forms an angle with the arrangement direction of the multiple sutures.
[0044] The included angle is not limited and can be set as needed. Generally speaking, the included angle between the length direction of the staple row 20 and the opening direction of the suture staple needs to be set in conjunction with the organ hemostasis suture device 10, which will be discussed later.
[0045] The organ hemostatic suture device 10 is mainly used to tilt and push out the suture staples in the staple row 20 one by one, and suture the suture staples to the wound of the organ.
[0046] The organ hemostasis suture device 10 mainly consists of an outer tube 11, a suture mechanism 13, and a handle assembly 12. The following is a detailed discussion of each component.
[0047] The outer tube 11 mainly serves as a support and connection, so that the front end of the organ hemostasis suture device 10 can be inserted into the patient's body for operation.
[0048] The outer tube 11 has a tubular structure, such as a square tube, a round tube, an elliptical tube, an irregularly shaped tube, or other various styles. In this embodiment, the outer tube 11 is preferably a round tube. The outer tube 11 can be a straight tube or a bent tube, or the front end of the outer tube 11 can be bent while the rest is a straight tube.
[0049] The length of the outer tube 11 is unlimited and can be set as needed, such as 5cm, 10cm, 20cm, etc.; the diameter of the outer tube 11 is unlimited, such as 5mm, 10mm, 22mm, etc.
[0050] For ease of description, the following definitions are made: In this embodiment, "front" and "back" are defined by their distance from the lesion site during use. The part closer to the lesion site is "front," and the part farther from the lesion site is "back." The front-back direction is the same as or substantially the same as the axis of the outer tube 11. Of course, "front" and "back" are only used to indicate relative positional relationships and are not absolute. They can be freely defined as needed.
[0051] The suturing mechanism 13 is located inside the front end of the outer tube 11. The front end of the suturing mechanism 13 can be exposed from the front end of the outer tube 11 or it can be completely located inside the outer tube 11. The suturing mechanism 13 is mainly used to hold the staple row 20 and push out the staples one by one in the first direction to suture the wound.
[0052] After the staple row 20 is placed inside the sewing mechanism 13, the length direction of the staple row 20 is consistent with or substantially consistent with the axial direction of the outer tube 11, that is, multiple staples are distributed along the front-back direction, and the opening direction of each staple is consistent with or substantially consistent with the first direction.
[0053] When the sewing mechanism 13 pushes out the suture staple, the suture staple will be pushed out along a first direction, which is set at an angle to the axis of the outer tube 11, that is, the first direction is inclined relative to the axis of the outer tube 11. It should be emphasized that the axis of the outer tube 11 does not require the outer tube 11 to be a straight or round tube. The axis of the outer tube 11 is defined as if the outer tube 11 were a straight or round tube. If the front end of the outer tube 11 is bent, then the axis of the outer tube 11 refers to the axis of the part of the outer tube 11 that is fitted with the sewing mechanism 13, that is, the front end of the outer tube 11. If the outer tube 11 is a square tube or an irregularly shaped tube, then the axis of the outer tube 11 is the direction of the centerline of the outer tube 11.
[0054] The angle between the first direction and the axis of the outer tube 11 is not limited, as long as it is greater than 0° and less than 90°, preferably 15°-60°, such as 30°, 40°, 52°, 60°, etc. During the testing process, the R&D personnel found that the effect was best when the angle was around 30°. This setting can satisfy the need to push out the suture staples without affecting the operator's field of vision.
[0055] The structure of the sewing mechanism 13 is not limited. In this embodiment, the following solutions can be adopted, but are not limited to: Please refer to... Figures 7-11 As shown, the suturing mechanism 13 includes a staple cartridge, a slide 140, a pressure tongue 150, and a staple presser 160.
[0056] The staple magazine is mainly used to hold the staple row 20 and gradually advance the staple row 20 forward. That is, when the suture staple at the front end of the staple row 20 sutures the organ wound and detaches from the staple row 20, the staple row 20 can move forward one unit.
[0057] The structure of the staple cartridge is not limited and can refer to the technical solutions in the prior art or the technical solutions of staplers. In this embodiment, the structure of the staple cartridge is as follows: the staple cartridge includes a staple cartridge seat 130, a staple pusher slider 131 and a staple pusher spring 132.
[0058] Please combine Figure 12 , Figure 13 As shown, the staple holder 130 is provided with a staple groove 133, which is used to hold the staple row 20. The style of the staple groove 133 is not limited, as long as it can allow the staple row 20 to be embedded in it.
[0059] The pusher slider 131 slides in conjunction with the staple cartridge seat 130. When the pusher slider 131 slides forward along the staple cartridge seat 130, it can push the staple row 20 forward along the axial direction of the outer tube 11. The front end of the pusher slider 131 is provided with a bevel, which matches the inclined suture staple at the rear end of the staple row 20.
[0060] The shape or structure of the pusher slider 131 is not limited. For example, it can be block-shaped, plate-shaped, or in various other styles, as long as it can push the nail row 20 forward.
[0061] The pusher spring 132 gives the pusher slider 131 a tendency to move forward. That is, without the action of external force, the pusher spring 132 can push the pusher slider 131 forward, thereby causing the nail row 20 to move forward.
[0062] The push pin spring 132 can be of various types, such as a tension spring, a compression spring, or a leaf spring. In this embodiment, the push pin spring 132 is a compression spring, with its front end abutting against the push pin slider 131 and its rear end abutting against the pin cartridge seat 130. To prevent the push pin spring 132 from detaching abnormally, in some embodiments, a guide rod can be provided at the rear end of the push pin slider 131 and / or the pin cartridge seat 130, and the guide rod can be inserted into the push pin spring 132.
[0063] The front end of the staple row 20 is limited by the staple cartridge seat 130 and / or the slide seat 140. That is, when the suture staple at the front end of the staple row 20 is not bent, deformed and dislodged, the staple cartridge seat 130 and / or the slide seat 140 will block the suture staple from moving forward.
[0064] The slide 140 corresponds to the front end of the staple cartridge. The slide 140 can be located above, below, or on both sides of the staple cartridge. The slide 140 is fixedly connected to the staple cartridge or to the outer tube 11. The connection method between the slide 140 and the staple cartridge or between the slide 140 and the outer tube 11 is not limited, such as bonding, pin fixing, snap-fit, etc.
[0065] Please combine Figure 14 As shown, the shape and structure of the slide 140 are not limited, such as block, frame structure, plate, etc. The slide 140 is provided with a push pin channel 141, which extends along the first direction. The direction of the push pin channel 141 is consistent with or substantially consistent with the inclination direction of the suture pin, and the two can be the same or approximately the same. The opening of the push pin channel 141 faces the suture pin at the foremost end of the suture pin row 20.
[0066] The pressure tongue 150 is slidably disposed within the pusher channel 141, and the pressure tongue 150 can move within the pusher channel 141 along a first direction. When the pressure tongue 150 moves toward the staple row 20, the pressure tongue 150 can push the suture staple located at the foremost end of the staple row 20 along the first direction; when the pressure tongue 150 moves away from the staple row 20, the pressure tongue 150 can disengage from the staple row 20, thereby allowing the staple row 20 to move forward under the action of the pusher spring 132.
[0067] The structure of the tongue depressor 150 is not limited; it can be plate-shaped, block-shaped, or in various other forms. In this embodiment, the following solutions can be adopted, but are not limited to: Please refer to... Figure 15 As shown, the depressor 150 is plate-shaped, and the front end of the depressor 150 is C-shaped or rectangular with an open front end, etc. The depressor 150 has two push blocks 152, which can abut against the two ends of the suture staple, i.e., the two ends of the bottom staple.
[0068] In existing technology, after the depressor 150 pushes out the suture staples, the shape of the staples does not change; that is, the angle between the side staples and the bottom staples does not change. This requires medical staff to manually or with instruments close and press the two sides of the wound together during suturing before pressing the suture staples in. Otherwise, it may result in a larger gap in the sutured wound and poor hemostasis. Of course, even with this procedure, the wound may still separate to both sides after suturing.
[0069] In this embodiment, the improvement can be achieved through the following technical solution: a first stop 134 is provided at the center of the front end of the staple cartridge 130, and second stops 142 are respectively provided on both sides of the front end of the slide 140. A staple removal notch 143 is formed between the two second stops 142, and the first stop 134 extends into the staple removal notch 143. The first stop 134 cannot completely close the staple removal notch 143. The first stop 134 is used to abut against the middle of the staple, and the two second stops 142 are used to abut against both ends of the staple, thereby preventing the staple from detaching from the staple row 20.
[0070] In the first direction, the first stop 134 is located directly in front of the push pin channel 141, so that when the suture pin is pushed in the first direction, the bottom pin of the suture pin will be blocked by the first stop 134.
[0071] When the depressor 150 tilts and pushes the two ends of the foremost suture staple, the base of the suture staple begins to bend and deform under the obstruction of the first stop 134. The base of the suture staple gradually bends into an arc shape, the side staples tilt towards the center, and the two side staples gradually move closer to each other until the two ends of the suture staple are no longer obstructed by the second stop 142 and enter the staple release notch 143. The bent suture staple can then detach from the staple row 20 through the staple release notch 143. Because the base of the foremost suture staple bends and the side staples move towards the center, while the shape of the other suture staples in the staple row 20 remains unchanged, the foremost suture staple will detach from the second suture staple or only have a very small connection. Generally speaking, the side staples of the foremost suture staple will completely detach from the side staples of the suture staples behind it, and the base of the foremost suture staple will completely detach from the base of the suture staples behind it or only have a very small connection. Even if the base of the foremost suture staple is only partially connected to the base of the rear suture staple, the two can be separated by shaking the organ hemostasis suture device 100.
[0072] Please combine Figure 16 As shown, the pin clamping member 160 is used to control the movement of the pin clamping tongue 150 within the pin pusher channel 141. The shape and structure of the pin clamping member 160 are not limited, such as semi-cylindrical, rectangular block, irregular shape, etc.
[0073] The pin clamping member 160 can slide along the axial direction of the outer tube 11. The sliding arrangement of the pin clamping member 160 is not limited. For example, the pin cartridge seat 130 or the outer tube 11 is provided with a slide, or the pin cartridge seat 130 and the outer tube 11 together form a slide, and the pin clamping member 160 is embedded in the slide.
[0074] The front end of the staple clamp 160 is provided with an inclined slide 161. The extension direction of the inclined slide 161 is not limited. For example, in the direction from front to back, the inclined slide 161 gradually approaches or moves away from the staple cartridge. In this embodiment, in the direction from front to back, the inclined slide 161 gradually approaches the staple cartridge.
[0075] The tongue 150 is provided with a sliding part 151. The style and position of the sliding part 151 are not limited. The sliding part 151 is embedded in the inclined slide 161. When the pressing pin 160 moves back and forth, the sliding part 151 can slide in the inclined slide 161, so that the tongue 150 slides in the slide block 140 along the first direction.
[0076] Furthermore, to facilitate the insertion of the organ hemostatic suture device 10 into the patient's body and to increase the surgical field of vision for medical personnel, in some embodiments, the front end face of the outer tube 11 can be configured as L-shaped, that is, the cross-section of the front end face is L-shaped, with the middle of the L-shape protruding forward relative to the sides, and the front end of the slide 140 and the front end of the staple cartridge can be flush with the front end face of the outer tube 11. Of course, in other embodiments, the front end face of the outer tube 11 can also be flat.
[0077] Since the organ hemostasis suturing device 100 needs to be inserted into the patient's body for operation, medical staff can grasp and operate it through the handle assembly 12 at the rear of the outer tube 11. The handle assembly 12 is mainly used to control the suturing mechanism 13 to push out the suture staples, that is, the handle assembly 12 is used to control the staple pressing member 160 to slide back and forth inside the outer tube 11.
[0078] The structure of the handle assembly 12 is not limited, as long as it can control the back-and-forth sliding of the pressure pin 160. Referring to existing technology, in this embodiment, the following solutions can be adopted, but are not limited to: Please refer to... Figure 17 , Figure 18 As shown, the handle assembly 12 includes a handle and a push rod 125.
[0079] The structure of the handle is not limited. For example, the handle includes a main body 120, a first handle 121 and a second handle 122. The first handle 121 is fixedly connected to the main body 120 or integrally formed. The second handle 122 is hinged to the main body 120 or the first handle 121. One end of the second handle 122 extends into the main body 120.
[0080] The structure of the push rod 125 is not limited; it can be rod-shaped, tubular, rope-shaped, etc., but rod-shaped is preferred. The front end of the push rod 125 is connected to the pressure pin 160, and the connection method is not limited. The rear end of the push rod 125 is connected to the handle, that is, the push rod 125 is connected to one end of the second handle 122, and the connection method is not limited, such as hinged connection. In this embodiment, one end of the second handle 122 is provided with a groove 123, and one side of the groove 123 is provided with a U-shaped notch. The rear end of the push rod 125 is provided with a T-shaped head 124, which is embedded in the U-shaped notch and partially located within the groove 123. When the second handle 122 rotates relative to the first handle 121, the groove 123 can pull the T-shaped head 124 forward or backward, thereby pulling the push rod 125 forward or backward. In some embodiments, the handle may also be provided with a return spring, which gives the second handle 122 a tendency to rotate and return to its original position. Generally, if a return spring is provided, the return spring needs to give the push rod 125 a tendency to move backward.
[0081] The method of using the organ hemostasis suture device 10 provided in this embodiment is as follows: The staple row 20 or a single sewing staple is inserted into the staple groove 133. Of course, the staple row 20 can also be pre-installed into the staple groove 133 during production. Medical staff insert the organ hemostasis and suturing device 100 into the patient's body, so that the front end is close to or in contact with the wound of the organ. Squeeze the handle to rotate the second handle 122 relative to the main body 120 or the first handle 121, and the second handle 122 will drive the push rod 125 to move forward; The push rod 125 drives the nail clamping member 160 to move forward, thereby pushing the pressure tongue 150 to slide towards the nail row 20 in the nail pusher channel 141; The pusher 152 of the depressor 150 abuts against the two ends of the bottom pin of the suture pin located at the front end of the pin row 20 and pushes the suture pin along the first direction; The bottom of the suture staple is blocked by the first stop 134, causing the bottom staple to gradually bend. During this process, the side staples gradually move towards the center. As the distance between the two ends of the bottom staple gradually decreases, the suture staple will squeeze the two sides of the organ wound towards the center, making the two sides of the wound fit more tightly. At this time, the second stop 142 can prevent the suture staple from flipping. Release the handle and the return spring will cause the second handle 122 to rotate in the opposite direction relative to the main body 120, or manually rotate the second handle 122 in the opposite direction relative to the main body 120, and the second handle 122 will pull the push rod 125 backward. The push rod 125 pulls the nail clamp 160 backward, thereby causing the pressure tongue 150 to slide away from the nail row 20 in the nail push channel 141; Medical staff gently shake the front end of the organ hemostatic suture device 10 to disengage the bent suture staple from the staple row 20 and from the staple disengagement notch 143. Repeat the above steps to insert several suture staples along the direction of the organ wound. Retrieve the organ hemostasis and suturing device 100.
[0082] The above steps can be added, removed, modified, or their order adjusted as needed. For example, if the first block 134 is not present, the relevant steps can be omitted.
[0083] In addition, please combine Figure 19 As shown, in some embodiments, additional stapling windows can be provided on one or both sides of the outer tube 11. The inner and outer sides of the outer tube 11 are connected by the additional stapling windows. The additional stapling windows can be through holes, and the shape of the additional stapling windows is not limited, such as circular, elongated, or oblong holes. The width and length of the additional stapling windows can be set as needed.
[0084] The staple insertion window is adjacent to the staple cartridge and can be located on one side of the staple slot 133. Medical staff can insert the staples into the outer tube 11 through the staple insertion window and embed the staples into the staple slot 133.
[0085] Accordingly, in order to insert the suture staple into the staple slot 133, a structure must be provided so that the staple pusher slider 131 is pulled back before the suture staple is inserted.
[0086] The structure for moving the pusher slider 131 backward is not limited. For example, sliders can be provided on one or both sides of the pusher slider 131, with the sliders passing through the outer tube 11, or the pusher slider 131 can be pushed backward by inserting an instrument into the staple cartridge seat 130.
[0087] In this embodiment, the following technical solution can be provided: the outer tube 11 and the staple cartridge seat 130 are respectively provided with staple insertion through holes 111. The shape of the staple insertion through holes 111 is not limited, such as square holes, round holes, irregular holes, etc. The diameter of the staple insertion through holes 111 is not limited and can be set as needed. A needle-like object can be inserted into the staple insertion through hole 111. The front end of the staple pusher slider 131 can move on both sides of the extension line of the staple insertion through hole 111. That is, when the staple pusher slider 131 slides back and forth, it can reach both the front and rear of the extension line of the staple insertion through hole 111. With this configuration, after the needle-like object is inserted into the staple insertion through hole 111, it can prevent the staple pusher slider 131 from sliding forward, thereby exposing the staple groove 133 in front of the staple pusher slider 131, which can be used to insert suture staples or staple rows 20.
[0088] If suture staples are required, the steps are as follows: Insert a sheet-like instrument, such as a metal sheet, into the staple cartridge 130 and push the staple pusher slider 131 backward. At this time, the staple pusher spring 132 is compressed. Insert a needle-like piece into the nail-attaching through-hole 111 and press it against the front end of the nail-attaching slider 131 to prevent the nail-attaching slider 131 from sliding forward. Use tweezers or manually to insert several suture staples into the outer tube 11 through the staple insertion window 110. At this time, the opening of the suture staple is roughly aligned with the axis of the outer tube 11. During this process, the suture staples can be inserted one by one, or a whole containing multiple suture staples can be inserted. It should be noted that if multiple suture staples are inserted as a whole, the number of suture staples should not be too many, such as two, three, four, etc. After the suture staple is inserted into place, rotate the suture staple at a certain angle so that the opening of the suture staple faces the first direction; When the needle-like component is released, the pusher spring 132 pushes the pusher slider 131 forward, and the pusher slider 131 pushes the suture nail forward and presses the suture nail against the first stop 134 of the suture cartridge seat 130 and the second stop 142 of the slide 140.
[0089] The above steps can be added, removed, modified, or their order adjusted as needed.
[0090] Example 2: Please refer to Figures 20-24 As shown, an embodiment of the present invention provides an organ hemostasis suture device 10, which is a further improvement on the first embodiment. The improvement is the addition of a staple removal component, which is used to push the bent and deformed staples away from the staple row 20. Other parts of the organ hemostasis suture device 10 not mentioned can be referred to, but are not limited to, the first embodiment or the prior art.
[0091] For specific details, please refer to... Figures 25-28 As shown, the nail removal assembly includes a nail removal component 170 and a pressing component 180.
[0092] The staple ejector 170 is slidably disposed in the staple cartridge, and the staple ejector 170 can slide back and forth relative to the staple cartridge seat 130. The sliding engagement method between the two is not limited.
[0093] The front end of the nail release component 170 is located inside the nail row 20, and the front end of the nail release component 170 is attached to or adjacent to the bottom of the nail row 20, i.e., the bottom nail.
[0094] The distance between the front end of the staple remover 170 and the bottom staple needs to meet the following conditions: when the staple is not bent, even if the staple remover 170 moves forward, it cannot stop the staple and push it forward; when the staple is bent under the obstruction of the first stop 134, the staple remover 170 can stop the staple when it moves forward.
[0095] The style of the nail release component 170 is not limited; it can be in the form of a sheet, a block, etc., but a sheet is preferred.
[0096] In this embodiment, please refer to Figure 29 As shown, the front end of the staple remover 170 is provided with two push heads 171. The front end of the staple remover 170, i.e., the push head 171, is adjacent to the bottom of the staple, and the push head 171 is either in contact with the staple or has a certain gap. The two push heads 171 are located on both sides of the first stop 134 and are configured to push away the bent staple. Of course, in other embodiments, the number of push heads 171 may also be one.
[0097] The pressing member 180 is configured to drive the nail-removing member 170 to move forward. The control method is not limited; for example, a handle can be added to the handle, and the pressing member 180 can adopt a push-pull rod structure. By controlling the rotation or sliding of the handle, the push-pull rod can move back and forth, thereby causing the nail-removing member 170 to move back and forth. In this embodiment, the following solutions can also be used, but are not limited to: Please refer to... Figure 30 As shown, the extruder 180 is configured to slide radially along the outer tube 11, and the stud 160 is provided with a radial groove 135 that extends approximately radially along the outer tube 11. The extruder 180 is slidably embedded in the radial groove 135.
[0098] Please combine Figure 31 As shown, the front end of the pressing member 180 is provided with a nail-removing ramp 182. The nail-removing ramp is inclined and forms an angle with the axial direction of the outer tube 11, with the angle between them being less than 90°. The nail-removing ramp abuts against the rear end of the nail-removing member 170. When the pressing member 160 moves forward, the nail-removing member 170 can retract; when the pressing member 160 moves backward, the nail-removing ramp can push the nail-removing member 170 forward.
[0099] The lower half or all of the transverse section of the extruded part 180 is in the shape of a straight line, a T-shape, or a cross shape. Preferably, please refer to... Figure 32 As shown, the lower half of the extruder 180 has a T-shaped transverse cross-section. Correspondingly, the transverse interface of the radial groove 135 is also T-shaped and matches the extruder 180. The radial groove 135 can penetrate the stud cartridge seat 130 and the outer tube 11. Under normal conditions, the bottom end of the extruder 180 can be flush with the outer surface of the outer tube 11 or slightly lower than the outer surface of the outer tube 11. When the extruder 180 slides radially along the outer tube 11, it can extend out of the outer tube 11. This design ensures that the extruder 180 is less likely to jam due to tilting under force during movement.
[0100] The retraction method of the ejector 170 is not limited and can be controlled by the extrusion member 180. That is, the rear end of the ejector 170 and the release slope of the extrusion member 180 are respectively provided with a sliding groove and a slider. The sliding groove and the slider cooperate so that the extrusion member 180 can move radially relative to the ejector 170 along the outer tube 11, and can also pull the ejector 170 to move back and forth.
[0101] In this embodiment, the retraction of the nail release member 170 can also be controlled by the nail pusher spring 132. That is, if the nail pusher spring 132 is a compression spring, the rear end of the nail pusher spring 132 abuts against the pressing member 180, causing the pressing member 180 to tend to move backward. The rear end of the pressing member 180 is provided with a J-shaped portion 172, that is, the rear end of the pressing member 180 is J-shaped and inclined, so as to better cooperate with the nail release slope 182 and the nail pusher spring 132.
[0102] The pressing component 160 moves back and forth, driving the pressure component to move radially along the outer tube 11. Its mechanism can refer to, but is not limited to, the following schemes: Please combine... Figure 33 As shown, the nail clamping member 160 is provided with an inclined nail removal groove 162, which gradually approaches the nail cartridge in the direction from front to back; the pressing member 180 is provided with a pressing slider 181, which is slidably embedded in the nail removal groove 162.
[0103] The working method of the organ hemostasis suture device 10 provided in this embodiment is as follows: When the pressing member 160 moves forward, the pressing slider 181 on the pressing member 180 moves along the nail removal groove 162, the pressing member 180 descends radially along the outer tube 11, and the rear end of the nail removal member 170 retracts under the action of the nail pusher spring 132. When the pressing member 160 moves forward, the pressing slider 181 on the pressing member 180 moves along the nail removal groove 162, the pressing member 180 descends radially along the outer tube 11, the nail removal slope 182 pushes the nail removal member 170 forward, the push head 171 abuts against the bent stitch and pushes it away from the nail row 20.
[0104] For other parts not mentioned, please refer to Embodiment 1 or the prior art.
[0105] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention.
