[0070] First, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0071] Secondly, it should be noted that in the description of the present invention, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0072] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0073] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0074] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0075] Due to the characteristics of its structure, the coil ligation device in the prior art has a limited length of elastic wire used. Therefore, during the operation, the coil ligation device needs to be replaced or the elastic wire needs to be reloaded multiple times, which increases the cost and prolongs the operation time. In order to solve the problem of high cost and long operation time of the coil ligation device in the prior art, the present invention provides an automatic elastic wire ligation stapler, which has a simple structure and can be operated with one hand; moreover, the automatic elastic wire ligation stapler is provided with at least one elastic wire mechanism, which can continuously operate on the target tissue without replacing the stapler or reloading the elastic wire, thereby reducing the operation cost and shortening the operation time.

[0076] Several optional implementations of the present disclosure are introduced below in conjunction with the accompanying drawings. Those skilled in the art should understand that the following implementations are only illustrative and not an exhaustive list. Based on these implementations, those skilled in the art may replace, splice or combine certain features or examples, which should still be regarded as the disclosed contents of the present disclosure.

[0077] like Figure 1 As shown, the automatic elastic thread ligation stapler 10 includes: a barrel 11, a handle 12, at least one elastic thread mechanism 13, a traction mechanism 14, a pushing mechanism 15 and a negative pressure mechanism 16, etc.

[0078] The gun barrel 11 has a first end and a second end, and a rotating member 111 is installed on the second end, and the handle 12 can be detachably connected through the rotating member 111. In this embodiment, there is no special restriction on the size and material of the gun barrel, and the size and material can be designed according to the target tissue, position and size of the target tissue. It can be understood that the diameter of the first end of the gun barrel 11 is not greater than the size of the target tissue.

[0079] Furthermore, a gun head is provided at the first end of the gun barrel 11, and the diameter of the gun head can be larger than the diameter of the gun barrel, but smaller than the size of the target tissue, so that the target tissue can be sucked into the gun head or the gun barrel 11 through the negative pressure mechanism 16, blocking the gun barrel 11, so that the gun barrel 11 maintains a negative pressure, and after the elastic line ligation is completed, the negative pressure can be released, and the target tissue is separated from the gun barrel after the ligation. The target tissue after the ligation cannot obtain blood to maintain the corresponding function, thereby causing the target tissue to necrotize and fall off.

[0080] like Figure 2 As shown, in some embodiments of the present invention, the handle 12 includes a first shell 121 and a second shell 122, and the first shell 121 and the second shell 122 cooperate with each other to form a chamber that can accommodate the traction mechanism 14, the pushing mechanism 15 and the negative pressure mechanism 16. In addition, the shape of the handle 12 is conducive to single-handed holding, thereby improving work efficiency.

[0081] As mentioned above, the handle 12 can be detachably connected to the second end of the barrel 11 through the rotating member 111. The detachable connection can facilitate the replacement of the barrel 11, and the detachable connection method is any detachable connection method known to those skilled in the art. In some embodiments of the present invention, the detachable connection method is a snap-on connection.

[0082] In the automatic elastic line ligation stapler provided by the present invention, the elastic line mechanism 13 includes an elastic line 131 and a pipe 133 for accommodating the elastic line, wherein the first end of the elastic line 131 has a slipknot coil 132, the coil 132 is sleeved on the first end of the barrel 11, and the second end of the elastic line 131 passes through the channel in the pipe 133 and is connected to the tail end of the pipe 133. During the operation, the coil 132 is sleeved on the target tissue under the traction of the traction mechanism 14. At this time, the pushing mechanism 15 pushes the pipe 133 from the rotating member 111, so that the pipe 133 is separated from the rotating member 111. For convenient operation, the barrel 11 and the handle 12 are moved out, and the inner diameter of the coil 132 is adjusted by tightening the elastic line 131 in the pipe 133 to achieve continuous tight pressure on the target tissue.

[0083] In the embodiments provided by the present invention, the number of elastic line mechanisms 13 can be adjusted according to the operation conditions. In some embodiments of the present invention, the automatic elastic line ligation stapler 10 includes three elastic line mechanisms 13, so that during the operation, there is no need to replace the stapler multiple times, which can further save the operation cost and shorten the operation time.

[0084] In order to be able to ligate the coil 132 on the target tissue, the automatic elastic thread ligation stapler of the present invention includes a traction mechanism 14, which is installed in the handle 12 and is used to pull the coil 132 away from the first end of the barrel 11 and ligate it on the target tissue.

[0085] Specifically, the traction mechanism 14 includes a driving wheel 141, a driven wheel 142, a conveyor belt 143, a rotating shaft 144, and a traction rope 145 located in the gun barrel 11. The driving wheel 142 is connected to the driven wheel 142 by transmission through the conveyor belt 143, and the rotating shaft 144 is connected to the driven wheel 142 to rotate with the driven wheel 142. The first end of the traction rope 145 is connected to the coil 132 along the length direction of the gun barrel 11, and the other end is wound around the rotating shaft 144. When the traction coil 132 is entangled with the target tissue, the driving wheel 141 is rotated to drive the driven wheel 142 and the rotating shaft 144 to rotate, thereby tightening the traction rope 145. During the tightening process, the traction rope 145 will pull the coil 132 away from the gun barrel 11. Since the target tissue is sucked into the gun barrel 11, the coil 132 that has been detached from the gun barrel 11 will be entangled with the target tissue, and the driving wheel 141 is stopped at this time.

[0086] Furthermore, the driving wheel 141 and the driven wheel 142 are provided with a plurality of gears, so that the friction between the driving wheel 141 and the conveyor belt 143 can be increased to drive the rotating shaft 144 to rotate, and the traction rope 145 wound on the rotating shaft 144 collects the traction rope 145 under the rotation of the rotating shaft 144. In order to prevent the traction rope 145 wound on the rotating shaft 144 from affecting the operation of other components or being affected by the operation of other components during the collection process, the traction mechanism 14 of the present invention further includes a wire box 146, through which the rotating shaft 144 passes to connect with the driven wheel 142, and the traction rope 145 passes through the wire box 146 and is wound around the rotating shaft 144 located in the wire box 146, so that the traction rope 145 can be prevented from being disturbed during the collection process.

[0087] In some embodiments of the invention, a wire box clamp 113 is installed on the barrel 11. When the automatic elastic thread ligation stapler 10 needs to be disassembled or assembled, the rotating shaft 144 passing through the wire box 146 can be clamped in the wire box clamp 113, thereby facilitating the assembly of the automatic elastic thread ligation stapler 10.

[0088] After the coil 132 is entrapped on the target tissue, when the inner diameter of the coil 132 needs to be adjusted, the pushing mechanism 15 installed in the handle 12 will push the pipe 133 containing the elastic wire 131 to separate from the rotating member 111. A certain force is applied to the separated pipe 133 so that the top of the pipe 133 presses against the slipknot of the coil 132, thereby reducing the inner diameter of the coil 132 and exerting continuous tight pressure on the target tissue.

[0089] In some embodiments of the present invention, the rotating member 111 includes a rotating tube 1111 and a mounting plate 1112, wherein the mounting plate 1112 is connected to the side wall of the rotating tube 1111. The pipe 133 mentioned above passes through the mounting plate 1112, and its tail protrudes from the mounting plate 1112, so that the pushing mechanism 15 can completely push the pipe 133 out of the mounting plate 1112, and the operator can adjust the inner diameter of the coil 132 through the pipe 133.

[0090] In some embodiments of the present invention, the pushing mechanism 15 includes a pushing member 151 and a driving member 152, wherein elastic members 153 are respectively provided on both sides of the pushing member 151, and the driving member 152 drives the pushing member 151 to act on the tail end of the pipe 133 to push the pipe 133 out of the mounting plate 1112, and then under the action of the elastic member 153, the pushing member 151 returns to the initial position.

[0091] Further, such as Figure 2 As shown, the push member 151 includes a first push member and a second push member, the first push member is vertically connected to the second push member, the first push member can contact the tail of the pipe 133, and the second push member is in contact with the driving member 152, wherein the driving member 152 can be a trigger and the elastic member 153 is a spring.

[0092] When ligating the target tissue, the target tissue needs to be sucked into the gun barrel 11 first. Therefore, the negative pressure mechanism 16 installed in the handle 12 and connected to the second end of the gun barrel 11 can achieve the above purpose, that is, the negative pressure mechanism 16 can form a negative pressure in the gun barrel 11 to suck the target tissue into the gun barrel 11.

[0093] Specifically, in some embodiments of the present invention, the negative pressure mechanism 16 includes: a first air pipe 161, a second air pipe 162 and a switch 163, wherein the first end of the first air pipe 161 is provided with a first air pipe joint, through which it can be communicated with the inner channel of the barrel 11, and the first end of the second air pipe 162 is connected to the second end of the first air pipe 161, and the second end thereof is provided with a negative pressure joint, through which a negative pressure device can be connected. The switch 163 can be provided on the first air pipe 161 or the second air pipe 162 to control the opening or closing of the negative pressure channel formed by the first air pipe 161 and the second air pipe 162. In some embodiments of the present invention, the switch 163 is provided on the second air pipe 162.

[0094] Furthermore, in order to facilitate the connection between the gun barrel 11 and the first air pipe 161, a gun barrel joint 112 is provided at the second end of the gun barrel 11, and the gun barrel 11 is connected to the first air pipe joint of the first air pipe 161 through the gun barrel joint 112 so that the gun barrel 11 is connected to the negative pressure mechanism 16. In addition, the traction rope 145 passes through the joint 112 and the silicone pad in sequence, and is wound around the rotating shaft 144.

[0095] During the operation on the target tissue, especially hemorrhoids, it is sometimes necessary to insert the ligation device into the anus of the patient. The ligation device in the prior art lacks a light source, which increases the difficulty of the operation. In some embodiments of the present invention, an LED light 17 is installed on the handle 12.

[0096] The following describes in detail the method of using the automatic elastic band ligation stapler provided by the present invention by performing a hemorrhoid surgery.

[0097] Aim the barrel of the automatic elastic thread ligation stapler at the hemorrhoids or the mucosa above the hemorrhoids, and after negative pressure is formed in the barrel, turn off the negative pressure switch, and the hemorrhoids or the mucosa above the hemorrhoids will be sucked into the barrel;

[0098] Rotate the rotating member so that the pipe containing the elastic wire is close to the edge of the clamping member of the wire box. At this time, the tail end of the pipe is aligned with the first pushing member.

[0099] The driving wheel is turned, and the driving wheel drives the driven wheel to rotate through the belt. Since the driven wheel is connected to the rotating shaft, the rotating shaft rotates with it, and then the traction rope is collected in the wire box. As the traction rope is tightened, it will drive the coil to move and take the coil away from the barrel, and finally be tied to the base of the hemorrhoids or the mucosa above the hemorrhoids;

[0100] When the trigger is clicked, the second pusher pushes the first pusher forward, thereby pushing the pipe containing the elastic wire out of the mounting plate of the rotating member. When the pipe is separated from the mounting plate, the negative pressure switch is turned on to keep the gun barrel consistent with the external pressure. At this time, the hemorrhoids or the mucosa above the hemorrhoids will leave the gun barrel.

[0101] Place the top of the tube against the hemorrhoids or the mucosa above the hemorrhoids, pinch the tail end of the tube and pull it backwards to reduce the inner diameter of the coil to apply tight pressure to the hemorrhoids or the mucosa above the hemorrhoids. After tightening, gently loosen the tail end of the tube and move the tube backwards;

[0102] Cut the elastic wire outside the slipknot of the coil, remove the excess elastic wire and pipe after cutting, and the operation of the first elastic wire is completed.

[0103] The operation steps for the second elastic line are the same as those for the first elastic line.

[0104] The operation steps of the third elastic line are the same as those of the first elastic line.

[0105] The steps for the fourth to sixth elastic lines are as follows:

[0106] Since the gun barrel in this embodiment is equipped with three elastic wires, when the fourth to sixth elastic wires are needed, the assembled gun barrel can be replaced. First, the handle is disassembled, the shaft and the wire box are pulled out, and the disassembled shaft is clamped in the wire box clamping part, and then the rotating tube is rotated counterclockwise to separate the gun barrel and the handle, and the gun barrel is taken out, and then the cylindrical pit in the gun barrel joint on the new gun barrel is aligned with the protruding cylinder of the first air pipe joint, and the anastomosis device is rotated clockwise by 5°, and the anastomosis device is slightly shaken. If the anastomosis device has no structural looseness, the gun barrel has been replaced. The fourth to sixth elastic wires are used in the same way as the first three.

[0107] Procedure for the seventh to ninth elastic cord: Replace the barrel the same way as for the fourth to sixth cords, and use it the same way as for the first to third cords.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
