Description

Technical Field

[0001] This invention relates to the field of endoscopic suturing technology, and more particularly to an endoscopic stapler-type suture device. Background Technology

[0002] Following endoscopic resection of a digestive tract, safe and effective wound closure is crucial for preventing complications and directly impacts the patient's recovery. While metal clip closure is a relatively simple technique among current mainstream methods, directly clamping the wound edges with metal clips, the clamping area and strength of these clips are limited, making them ineffective for larger wounds and suitable only for small incisions.

[0003] Traditional suture techniques rely on curved needles combined with grasping forceps. Within the confined space of an endoscope, this requires extremely high precision from the surgeon, making it difficult and prone to damaging surrounding tissues with even slight errors. Existing technologies have limitations in handling larger wounds, ease of operation, safety, equipment compatibility, and learning curve. Therefore, there is an urgent clinical need to develop a novel, efficient, safe, easy-to-operate, and highly adaptable endoscopic wound suturing device to improve surgical safety and patient outcomes.

[0004] Based on this, the present invention designs an endoscopic stapler-type suture device to achieve rapid suturing of gastric cavity wounds. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide an endoscopic stapler-type suture device to solve the problem that existing endoscopic suture devices are unable to quickly suture large wounds inside the gastric cavity.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] An endoscopic stapler-type suture device includes: a suture device housing, a staple plate, suture staples, a staple disk, and a pneumatic drive module;

[0008] The suture staples are engaged in the suture staple mounting holes of the staple tray; the pneumatic drive module is used to eject the suture staples from the suture staple mounting holes;

[0009] The staple plate is fixedly installed at the end of the suture device housing and is arranged parallel to the staple disk; when the staple is driven by the pneumatic drive module and ejected from the staple mounting hole, the end of the staple can impact and deform with the staple plate; after the staple is deformed, it can fasten the wound to be sutured.

[0010] Furthermore, the suture pin includes: a tail pin ring, a pin post body, and pin head teeth; the diameter of the tail pin ring is larger than the diameter of the pin post body; at least two pin head teeth are provided, and the pin head teeth undergo lateral deformation when the suture pin is squeezed and impacted by the pin plate.

[0011] Furthermore, the nail plate is provided with an annular boss that is higher in the middle and lower at the edges; the annular boss is used to guide the deformation direction of the nail head teeth.

[0012] Furthermore, the nail disk has a cylindrical structure.

[0013] Furthermore, the nail disc is rotatably mounted on the nail disc mounting part at the end of the suture housing and is detachably connected.

[0014] Furthermore, the axis of the suture pin mounting hole is parallel to the axis of the pin disc.

[0015] Furthermore, the staple tray is provided with a plurality of staple mounting holes, and the plurality of staple mounting holes are equally spaced around the central axis of the staple tray.

[0016] Furthermore, it also includes a rotary drive assembly; the rotary drive assembly is used to drive the staple disk to rotate, thereby enabling the alignment of the staples in different staple mounting holes with the annular boss.

[0017] Furthermore, the rotary drive assembly includes: a drive gear, a gear shaft, a drive coil, and a rotary winding shaft; an external gear ring is provided on the outside of the stapler disc, and the external gear ring meshes with the drive gear; the drive gear is rotatably mounted inside the suturer housing via the gear shaft; the drive coil is a ring coil, one end of which is wound around the gear shaft, and the other end is wound around the rotary winding shaft; the rotary winding shaft is rotatably mounted on the operating end of the suturer housing; when the rotary winding shaft rotates, it can pull the gear shaft to rotate synchronously via the drive coil.

[0018] Furthermore, the drive coil is wound multiple times on both the gear shaft and the rotating winding shaft, and the middle part of the drive coil wound on the gear shaft and the rotating winding shaft is fixed to the gear shaft and the rotating winding shaft by bonding or welding.

[0019] Furthermore, the pneumatic drive module includes: a telescopic push rod, a drive air chamber, an inflation pump, and a deflation pump; the inflation pump is used to inflate the drive air chamber, thereby pushing the telescopic push rod to extend; the deflation pump is used to deflate the drive air chamber, thereby driving the telescopic push rod to retract.

[0020] Furthermore, the telescopic push rod is a two-stage push rod, comprising: a first push rod and a second push rod; the first push rod is slidably nested inside the driving air chamber and is sealed; the second push rod is slidably nested inside the first push rod and is sealed.

[0021] Furthermore, the inside of the sewing machine housing is provided with a circular traction wire mounting hole; a traction wire is installed in the traction wire mounting hole; one end of the traction wire is provided with a spiral traction part, and the other end is provided with a traction handle.

[0022] The technical solution of this invention can achieve at least one of the following effects:

[0023] 1. The endoscopic stapler-type suture device of the present invention uses a pneumatic drive module to eject the staples from the staple tray. After being ejected, the staples hit the opposite staple plate and bend and deform under the impact of the staple plate. After deformation, it can fix the tissues on both sides of the wound, realize rapid suturing, have high suturing efficiency, and can be applied to the suturing of larger wounds.

[0024] 2. The endoscopic stapler-type suture device of the present invention uses a ring-shaped drive coil to drive the drive gear to rotate, thereby driving the staple tray to rotate. This aligns the multiple staple mounting holes on the staple tray with the staple plate, and then the pneumatic drive module sequentially ejects multiple staples for continuous suturing of the wound. Furthermore, the staple tray and the suture device housing of the present invention are detachable. After a set of staples is used up, the suture device can be removed from the endoscope and the staple tray can be removed for staple refilling, so as to meet the need for continuous use of multiple sets of staples without replacing the suture device. This facilitates rapid suturing of gastric wounds while also taking into account hygiene and economics.

[0025] 3. In order to achieve the suturing effect on large wounds, the endoscopic stapler of the present invention is provided with a traction wire, and the end of the traction wire is provided with a spiral traction part. The spiral traction part can be screwed into the tissue to be sutured and pulled to place the tissue in an area that can be penetrated by the staple.

[0026] 4. The endoscopic stapler-type suture device of the present invention has the advantages of convenient operation, large closure area, firm fixation effect, and no need for sutures. It can fully meet the increasing clinical demand for endoscopic suturing devices in digestive endoscopy operations and further improve the safety of digestive endoscopy surgery.

[0027] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

Detailed Implementation

[0048] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0049] Example 1

[0050] One specific embodiment of the present invention discloses an endoscopic stapler-type suture device, such as... Figure 1 , Figure 2As shown, it includes: a suture device housing 1, a staple plate 2, suture staples 4, a staple tray 5, and a pneumatic drive module 6; the suture staples 4 are engaged in the suture staple mounting holes 501 of the staple tray 5; the pneumatic drive module 6 is used to eject the suture staples 4 from the suture staple mounting holes 501; the staple plate 2 is fixedly installed at the end of the suture device housing 1 and is arranged parallel to the staple tray 5; when the suture staples 4 are ejected from the suture staple mounting holes 501 under the drive of the pneumatic drive module 6, the end of the suture staples 4 can impact and deform with the staple plate 2; after deformation, the suture staples 4 can fasten the wound to be sutured.

[0051] In one specific embodiment of the present invention, such as Figure 13 , Figure 14 As shown, the suture nail 4 includes: a tail nail ring 401, a nail post body 402, and a nail head tooth 403; the diameter of the tail nail ring 401 is larger than the diameter of the nail post body 402; at least two nail head teeth 403 are provided, and the nail head teeth 403 undergo lateral deformation when the suture nail 4 is squeezed and impacted by the nail plate 2.

[0052] Preferably, three nail head teeth 403 are evenly spaced along the circumference of the nail post body 402; the nail head teeth 403 are thin sheet structures with pointed tips.

[0053] Furthermore, such as Figure 4 , Figure 7 As shown, the nail plate 2 is provided with an annular boss 201 that is high in the middle and low at the edges; the annular boss 201 is used to guide the deformation direction of the nail head tooth 403.

[0054] Specifically, such as Figure 7 As shown, the annular boss 201 has a mountain-shaped structure with a high center and low edges.

[0055] During implementation, after the suture staple 4 passes through the tissue to be sutured, the staple head teeth 403 at its end contacts the annular curved surface of the annular boss 201. The staple head teeth 403 will slide along the side of the annular boss 201 and then bend and deform. After deformation, it can restrict the human tissue, so that the tissue around the wound can be restricted between the deformed staple head teeth 403 and the tail staple ring 401, thereby achieving rapid suturing of the wound.

[0056] In this embodiment, the deformation of the staple head tooth plate 403 is guided by the annular boss 201, so that the staple 4 undergoes a certain and reliable deformation mode after impact with the staple plate 2, and finally ensures the staple 4's fastening effect on the wound tissue.

[0057] Furthermore, such as Figure 7As shown, the annular boss 201 has a staple ejection groove 202 on its upper side; after one staple 4 has finished suturing the wound, the retraction of the suture device can allow the staple 4 to slide out of the staple ejection groove 202, thereby releasing the staple 4.

[0058] Furthermore, such as Figure 8 , Figure 9 As shown, the staple tray 5 has a cylindrical structure; the staple tray 5 is rotatably mounted on the staple tray mounting part 101 at the end of the suture housing 1 and is detachably connected; the axis of the staple mounting hole 501 is parallel to the axis of the staple tray 5; the staple tray 5 is provided with a plurality of staple mounting holes 501, and the plurality of staple mounting holes 501 are equally spaced around the central axis of the staple tray 5.

[0059] like Figure 6 , Figure 9 As shown, the inner side of the nail tray mounting part 101 is provided with a circular concave nail tray mounting groove 107; the side of the nail tray 5 is provided with a protruding rotary positioning shaft 503; the rotary positioning shaft 503 is mounted in the nail tray mounting groove 107 by a bearing. Specifically, a bearing is provided in the nail tray mounting groove 107, and the outer ring of the bearing is fixed to the nail tray mounting groove 107 by bonding or welding; the inner ring of the bearing is inserted into the rotary positioning shaft 503 on the side of the nail tray 5.

[0060] In practice, the detachable connection of the staple tray 5 to the staple tray mounting part 101 allows for rotational connection or separation between the staple tray 5 and the suture device housing 1 by inserting or removing the rotating positioning shaft 503 from the inner ring of the bearing. This enables the addition of sutures 4 to the suture mounting holes 501 of the staple tray 5. By making the staple tray 5 and the suture device housing 1 detachably mounted, after one set of sutures 4 is used up, the suture device can be removed from the endoscope, and the staple tray 5 can be disassembled for refilling. This satisfies the need for continuous use of multiple sets of sutures without replacing the suture device, facilitating rapid and complete suturing of gastric wounds while also considering hygiene and economics.

[0061] In one specific embodiment of the present invention, a rotation drive assembly is further included; the rotation drive assembly is used to drive the nail disk 5 to rotate, thereby enabling the alignment of the suture nail 4 in different suture nail mounting holes 501 with the annular boss 201.

[0062] Furthermore, such as Figure 11 , Figure 12As shown, the rotary drive assembly includes: a drive gear 11, a gear shaft 13, a drive coil 12, and a rotary winding shaft 14; an external gear ring 502 is provided on the outside of the stapler disc 5, and the external gear ring 502 meshes with the drive gear 11; the drive gear 11 is rotatably mounted inside the suturer housing 1 via the gear shaft 13; the drive coil 12 is a ring coil, one end of the drive coil 12 is wound around the gear shaft 13, and the other end is wound around the rotary winding shaft 14; the rotary winding shaft 14 is rotatably mounted on the operating end of the suturer housing 1; when the rotary winding shaft 14 rotates, it can pull the gear shaft 13 to rotate synchronously via the drive coil 12.

[0063] Furthermore, such as Figure 12 As shown, the drive coil 12 is wound multiple times on both the gear shaft 13 and the rotating winding shaft 14, and the middle part of the drive coil 12 wound on the gear shaft 13 and the rotating winding shaft 14 is fixed to the gear shaft 13 and the rotating winding shaft 14 by bonding or welding.

[0064] Specifically, such as Figure 5 As shown, the operating end of the suture housing 1 is also provided with a rotating handle 7; the rotating handle 7 is rotatably mounted on the suture housing 1 and fixedly connected to the internal rotating winding shaft 14; when the rotating handle 7 rotates, it can drive the internal rotating winding shaft 14 to rotate, thereby driving the coil 12 on one side to wind around the rotating winding shaft 14, and the coil 12 on the other side to unwind from the rotating winding shaft 14, realizing the rotation of the driving coil 12; during the rotation of the rotating winding shaft 14, the driving coil 12 on one side wound around the rotating winding shaft 14 pulls the gear shaft 13 to rotate, while the driving coil 12 on the other side unwinding from the rotating winding shaft 14 gradually screws onto the gear shaft 13, realizing the synchronous rotation of the gear shaft 13, the driving gear 11, the rotating winding shaft 14, and the rotating handle 7.

[0065] In this embodiment, a ring-shaped drive coil 12 is used to drive the drive gear 11 to rotate, thereby driving the staple disk 5 to rotate, so that the multiple staple mounting holes 501 on the staple disk 5 are aligned with the staple plate 2, and then multiple staples can be ejected sequentially by the pneumatic drive module 6 to continuously suture the wound.

[0066] Preferably, four suture staples 4 are installed on the staple plate 5, and one suture staple 4 is switched to align with the annular boss 201 on the staple plate 2 every 90° rotation.

[0067] Preferably, the meshing transmission ratio between the drive gear 11 and the external gear ring 502 is set to 4:1; that is, for every rotation of the drive gear 11, it can drive the external gear ring 502 to rotate one-quarter of a rotation (90°).

[0068] In one specific embodiment of the present invention, such as Figure 16 As shown, the pneumatic drive module includes: a telescopic push rod 102, a drive air chamber 104, an inflation pump 601, and a de-inflation pump 602; the inflation pump 601 is used to inflate the drive air chamber 104, thereby pushing the telescopic push rod 102 to extend; the de-inflation pump 602 is used to de-inflate the drive air chamber 104, thereby driving the telescopic push rod 102 to retract.

[0069] like Figure 16 As shown, the driving air chamber 104 is connected to the inflation pump 601 via the air inlet duct 105, and simultaneously connected to the suction pump 602 via the air outlet duct 106. Further, an air inlet valve 603 is provided on the air inlet duct 105, and an air outlet valve 604 is provided on the air outlet duct 106; in practice,

[0070] Furthermore, the pneumatic drive module 6 integrates a pneumatic control circuit board, which controls the inflation pump 601 to inflate the drive air chamber 104, the de-inflation pump 602 to de-inflate the drive air chamber 104, and the opening and closing of the inlet valve 603 and the outlet valve 604.

[0071] like Figure 3 As shown, an inflation button 8 and an air extraction button 9 are provided at the operating end of the suture device housing 1. These buttons are used to control the inflation and deflation of the inflation pump 601 and the air extraction pump 602, as well as the opening and closing of the inlet valve 603 and the outlet valve 604. Specifically, when the inflation button 8 is pressed, the inlet valve 603 opens and the outlet valve 604 closes. At the same time, the inflation pump 601 rapidly inflates the drive air chamber 104, thereby driving the suture staples 4 to be ejected. When the air extraction button 9 is pressed, the outlet valve 604 opens and the inlet valve 603 closes. At the same time, the air extraction pump 602 rapidly extracts air from the drive air chamber 104, thereby driving the telescopic push rod 102 to retract under negative pressure, thus avoiding affecting the rotation of the staple disc 5.

[0072] Furthermore, such as Figure 17 As shown, the telescopic push rod 102 is a two-stage push rod, including: a first push rod 1021 and a second push rod 1022; the first push rod 1021 is slidably nested inside the driving air chamber 104 and in sealed contact; the second push rod 1022 is slidably nested inside the first push rod 1021 and in sealed contact.

[0073] Specifically, when the telescopic push rod 102 extends, it can eject the suture nail 4 from the suture nail mounting hole 501. When the telescopic push rod 102 retracts, the nail disc 5 can rotate relative to the nail disc mounting part 101, thereby enabling the switching of the next suture nail 4 for suturing.

[0074] In another specific embodiment of the present invention, a protruding annular sealing ring is provided on the outer side of the driving air chamber 104, and when the suture mounting hole 501 on the suture disc 5 is aligned with the driving air chamber 104, the driving air chamber 104 can be inflated by the air pump 601 to achieve pneumatic ejection of the suture 4. In this embodiment, only one air pump 601 is required and the telescopic push rod 102 is not required.

[0075] In one specific embodiment of the present invention, such as Figure 5 As shown, the inside of the suture housing 1 is provided with a traction wire mounting hole 103; a traction wire 3 is installed in the traction wire mounting hole 103.

[0076] Specifically, such as Figure 10 As shown, one end of the traction wire 3 is provided with a spiral traction part 15, and the other end is provided with a traction handle 10.

[0077] Furthermore, two traction wire mounting holes 103 are arranged side by side along the axis of the staple plate 5. When the wound is large, two traction wires 3 are needed to pull the tissue on both sides of the wound. Two traction wires 3 are installed in the two traction wire mounting holes 103 and screwed into the tissue, and the tissue structure on both sides of the wound is pulled between the staple plate 5 and the staple plate 2. The suture staples 4 are then ejected to achieve stapled closure of the tissue on both sides.

[0078] The process of using the endoscopic stapler-type suture device of the present invention is as follows:

[0079] First, multiple suture staples 4 are loaded into the staple tray 5; then the staple tray 5 is rotated and mounted onto the staple tray mounting part 101 at the end of the sewing machine housing 1.

[0080] Next, the suture device is inserted into the working channel of the digestive endoscope (hereinafter referred to as endoscope), and the suture device is then inserted into the stomach cavity to the location of the wound to be sutured through the endoscope.

[0081] Furthermore, the traction wire 3 is inserted into the traction wire mounting hole 103, and the traction wire 3 is rotated to screw the spiral traction part 15 at its end with the tissue on the side of the wound; one or two traction wires 3 can be inserted as needed.

[0082] Furthermore, by pulling the traction handle 10 at the operating end, the tissue near the wound is pulled between the staple plate 5 and the staple plate 2 of the suture device.

[0083] Furthermore, pressing the inflation button 8 inflates the drive air chamber 104 via the inflation pump 601, thereby pushing the telescopic push rod 102 to extend rapidly. The telescopic push rod 102 aligns with the suture nails 4 inside the nail tray 5, and pushes the suture nails 4 in the nail tray 5 out through the telescopic push rod 102 (pushed out by the telescopic push rod 102).

[0084] Furthermore, after the suture staple 4 is ejected, it impacts the staple plate 2, and the staple head teeth 403 at the end of the suture staple 4 bends and deforms outward under the guidance of the annular boss 201 on the staple plate 2. After deformation, the suture staple 4 can staple the wound tissue together; such as Figure 15 As shown.

[0085] Furthermore, the traction wire 3 is rotated to separate it from the wound tissue; and the suture device is dragged away from the wound, so that the suture staple 4, which is attached to the wound, separates from the main structure of the suture device.

[0086] Furthermore, the rotating handle 7 of the rotating operating end drives the rotating winding shaft 14 to rotate; then the drive coil 12 pulls the gear shaft 13 to rotate; the gear shaft 13 drives the drive gear 11 to rotate, and then the drive gear 11 and the outer gear ring 502 on the outside of the nail plate 5 drive the nail plate 5 to rotate, switching the next suture nail 4 to align with the annular boss 201 on the nail plate 2, and then repeating the above steps to perform the suturing operation of the next suture nail 4.

[0087] The suture device of this embodiment has the advantages of convenient operation, large closure area, firm fixation effect, and no need for sutures, which can fully meet the increasing clinical demand for endoscopic suturing devices in the practice of digestive endoscopy.

[0088] It is worth noting that:

[0089] The staple tray 5 of the endoscopic stapler of the present invention is detachably connected to the stapler housing 1. When a set of staples is used up, the stapler can be removed from the endoscope and the staple tray 5 can be removed to refill the staples 4, so as to meet the need for continuous use of multiple sets of staples 4 without replacing the stapler, which facilitates rapid suturing of gastric wounds, while also taking into account health and economics.

[0090] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
