Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0047] In the related art, staplers can staple tissues with staples while cutting, and are widely used for cutting, suturing or anastomosis of organs such as intestines, stomach, lungs, and pancreas. However, due to the differences in soft tissue properties in different regions, some soft tissues, such as lungs, have low strength and may be at risk of tearing at the anastomosis. In this regard, a conveyor is needed to transport the clamp to the anastomosis and clamp it to avoid leakage and bleeding at the anastomosis.

[0048] In view of this, the present disclosure provides a conveyor, comprising: a clamp assembly having a natural state and a clamped state; a conveyor body, configured to control the rotation of the clamp assembly or switch between the natural state and the clamped state; a conveying rod assembly, wherein both ends of the conveying rod assembly are respectively connected to the conveyor body and the clamp assembly, and configured to respond to the transmission of the conveyor body to control the movement of the clamp assembly.

[0049] The conveyor provided by the present invention can convey the clamp to the anastomosis, and use the clamp assembly to close the anastomosis. The clamp assembly is controlled to rotate by the conveyor body so that the clamp is facing the anastomosis, thereby achieving accurate clamping of the clamp and the anastomosis to avoid leakage and bleeding of the anastomosis.

[0050] The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0051] The embodiment of the present disclosure provides a conveyor 1000, which comprises: a clamp assembly 100, a conveyor body 300 and a conveyor rod assembly 200. Figure 1 As shown, the clamp assembly 100 is connected to the conveyor body 300 through the conveyor rod assembly 200. The conveyor body 300 is configured to control the rotation or clamping of the clamp assembly 100. The clamp assembly 100 has a natural state and a clamping state, and is configured to assist in the clamping of the anastomosis.

[0052] In order to more clearly describe the operation of the conveyor 1000, the following directions are defined based on the conveyor 1000: the front-rear axis X, the transverse axis Y and the vertical axis Z. The direction opposite to the arrow along the front-rear axis X, i.e., the forward moving direction of the conveyor 1000 in normal operation, is marked as "forward", and the direction along the arrow direction of the front-rear axis X, i.e., the backward direction of the conveyor 1000 in normal operation, is marked as "backward", wherein the direction of the front-rear axis X is the first direction. The transverse axis Y is substantially along the width of the conveyor 1000, the direction opposite to the arrow along the transverse axis Y is marked as "left", and the direction along the arrow direction of the transverse axis Y is marked as "right", wherein the direction of the transverse axis Y is the second direction. The vertical axis Z extends along the vertical direction of the conveyor 1000, the direction opposite to the arrow along the straight axis Z is marked as "downward", and the direction along the arrow direction of the straight axis Z is marked as "upward", wherein the direction of the vertical axis Z is the third direction.

[0053] like Figure 1 As shown, the conveying rod assembly 200 extends along a first direction, and two ends of the conveying rod assembly 200 are respectively connected to the clamp assembly 100 and the conveyor body 300 , and the conveyor body 300 is configured to control the rotation or clamping of the clamp assembly 100 .

[0054] In some embodiments, the conveyor 1000 also includes a rotating assembly 210, which is rotatably disposed on the conveying rod assembly 200 and is configured to enable the conveying rod assembly 200 to drive the clamp assembly 100 to rotate around the first direction, thereby changing the orientation of the clamp assembly 100 relative to the anastomosis, so that the orientation of the clamp assembly 100 is easier to clamp the anastomosis.

[0055] In some embodiments, the clamp assembly 100 includes: a support module 110 and a first dial wheel module 121. The support module 110 includes a support base plate 111 and a support frame 112. Figure 2 As shown, the support frame 112 is arranged in pairs on the support base plate 111, and is configured to be connected to the first dial wheel 121 module 120. The first dial wheel 121 module 120 includes a first dial wheel 121 and a support plate 122. The first dial wheel 121 is rotatably connected to the support frame 112, and is configured to make the free end of the support plate 122 approach or move away from the support base plate 111. The surface of the first dial wheel 121 is provided with a first through hole 101, and the first through hole 101 penetrates the first dial wheel 121 along the second direction, and is configured to connect the first dial wheel 121 with other components to achieve transmission.

[0056] In some embodiments, Figure 3 As shown, the conveyor 1000 further includes a first sleeve rod 130, which passes through the first through hole 101 and connects the first thumbwheel 121 to at least part of the conveyor rod assembly 200. In response to the conveyor rod assembly 200 moving backward in the first direction, the first thumbwheel 121 rotates clockwise around the second direction to move the support plate 122 away from the support base plate 111; in response to the conveyor rod assembly 200 moving forward in the first direction, the first thumbwheel 121 rotates counterclockwise around the second direction to move the support plate 122 closer to the support base plate 111. The clamp assembly 100 has a natural state in which the support plate 122 is away from the support base plate 111 and a clamping state in which the support plate 122 is close to the support base plate 111. When the clamp assembly 100 is in the clamping state, the support plate 122 is close to the support base plate 111 to assist in the clamping of the anastomosis.

[0057] In some embodiments, Figure 3As shown, the clamp assembly 100 further includes a mounting member 140, and a mounting portion 143 is provided on the surface of the mounting member 140. In response to the first thumbwheel 121 and the module 120 being parallel to the support base plate 111, the two mounting members 140 are positioned opposite each other. The mounting members 140 are arranged in pairs, including a first mounting member 141 and a second mounting member 142. The two mounting members 140 are fixedly connected to the support plate 122 and the support base plate 111, respectively. In response to the support plate 122 approaching or moving away from the support base plate 111 under the action of an external force, the first mounting member 141 approaches or moves away from the second mounting member 142, so that the clamp assembly 100 switches between the natural state and the clamping state, thereby achieving the clamping or releasing of the anastomosis.

[0058] In some embodiments, the mounting member 140 is rotatably connected to the supporting base plate 111 via a shaft. Specifically, the shaft passes through the connecting base plate and is fixedly connected to the mounting member 140. External force can be applied to the shaft or directly to the mounting member 140 to achieve the rotation of the mounting member 140. Further, the conveyor 1000 further includes a connecting rod assembly 150, and the connecting rod assembly 150 includes a first connecting rod 151 and a second connecting rod 152. The first connecting rod 151 and the second connecting rod 152 are rotatably connected. Figure 3 As shown, one end of the first connecting rod 151 is fixedly connected to the shaft of the mounting member 140, and the other end of the first connecting rod 151 is rotatably connected to the second connecting rod 152; the two ends of the second connecting rod 152 are respectively connected to the first connecting rod 151 and at least part of the conveying rod assembly 200. In response to the conveying rod assembly 200 moving in the first direction, the mounting member 140 rotates around the third direction.

[0059] In some embodiments, Figure 4 , Figure 5As shown, the conveyor body 300 includes a handle assembly 400, at least part of which is connected to the conveyor rod assembly 200, and is configured to control at least part of the clamp assembly 100 to move in the third direction. The handle assembly 400 includes: a pressing member 410 and a linkage member 420. The pressing member 410 is arranged inside the conveyor body 300, connected to at least part of the conveyor rod assembly 200, and is configured to drive the conveyor rod assembly 200 to move. At least part of the pressing member 410 is arranged outside the conveyor body and is movably connected to the linkage member 420, and is configured to control the linkage member 420 to move in the first direction. Among them, the conveyor body 300 is provided with an elastic member 310, and the two ends of the elastic member 310 are respectively stopped against the inner wall of the conveyor body 300 and the linkage member 420, so that the linkage member 420 has a tendency to move forward in the first direction. When no external force acts on the linkage member 420, the linkage member 420 will move forward along the first direction under the action of the elastic member 310 to drive the delivery rod assembly 200 to move forward along the first direction. Further, driven by the delivery rod assembly 200, the first thumbwheel 121 rotates counterclockwise around the second direction, and the clamp assembly 100 switches from a natural state to a clamped state. When the clamp assembly 100 is in the clamped state, the support plate 122 is close to the support base plate 111 to assist in the clamping of the anastomosis.

[0060] In some embodiments, the pressing member 410 includes a pressing handle 411, a stop portion 412, and a connecting portion 413. Figure 5 As shown, the pressing handle 411 is disposed outside the conveyor body 300 and is configured to drive the pressing member 410 to move along the first direction under the action of an external force. In response to the pressing handle 411 being free from the action of an external force, the abutment portion 412 abuts against at least part of the linkage member 420 to limit the linkage member 420 from moving in the first direction. The connecting portion 413 is configured to movably connect the pressing member 410 with the linkage member 420, and in response to the pressing member 410 moving backward, the linkage member 420 moves forward. Specifically, when an external force acts on the pressing handle 411 to cause the pressing member 410 to move backward, the pressing member 410 rotates counterclockwise around the second direction with the connecting portion 413 as an axis. At this time, the stop portion 412 is separated from the linkage member 420, and the linkage member 420 moves forward along the first direction under the elastic action of the elastic member 310, that is, under the action of the external force, the pressing member 410 moves in opposite directions to the linkage member 420. Further, the clamp assembly 100 is switched from the natural state to the clamped state. The process of switching the clamp assembly 100 from the natural state to the clamped state has been described in detail above and will not be repeated here.

[0061] In some embodiments, Figure 5 , Figure 6 As shown, the conveying rod assembly 200 includes an axis core 220 and a first sleeve 221, and the axis core 220 is connected to the clamp assembly 100 and configured to keep the clamp assembly 100 stable relative to the conveyor body 300. The first sleeve 221 is sleeved on the axis core 220, and the two ends are respectively connected to the first sleeve rod 130 and the handle assembly 400. In response to the movement of the handle assembly 400 under the action of an external force, the first sleeve rod 130 moves synchronously with the linkage member 420 of the handle assembly 400, and is configured to drive the first impeller assembly to move so that the clamp assembly 100 switches between the natural state and the clamping state.

[0062] Specifically, the first sleeve rod 130 connects the first dial 121 with the first sleeve 221. In response to the first sleeve 221 moving backward in the first direction, the first dial 121 rotates clockwise around the second direction to move the support plate 122 away from the support base 111. In response to the first sleeve 221 moving forward in the first direction, the first dial 121 rotates counterclockwise around the second direction to move the support plate 122 closer to the support base 111. Further, in response to the external force acting on the pressing handle 411 to move the pressing member 410 backward, the pressing member 410 rotates counterclockwise around the second direction with the connecting portion 413 as the axis. At this time, the stop portion 412 is disengaged from the linkage member 420, and the linkage member 420 moves forward along the first direction under the elastic action of the elastic member 310. At this time, the first sleeve 221 moves forward along the first direction driven by the linkage member 420, so that the support plate 122 is close to the support base plate 111, so that the clamp assembly 100 is switched from the natural state to the clamping state.

[0063] In some embodiments, the conveyor 1000 further includes a second thumbwheel 321 module 320, which is movably disposed on the conveyor body 300 and configured to drive at least a portion of the rotation of the clamp assembly 100. The second thumbwheel 321 module 320 includes a second thumbwheel 321 and a second lever 322, the second lever 322 is connected to the second thumbwheel 321, and at least partially extends to the outside of the conveyor body 300, and is configured to drive the second thumbwheel 321 to rotate under the action of an external force. The second thumbwheel 321 is disposed inside the conveyor body 300, and rotates synchronously with the second lever 322, and a second through hole 302 is provided on the thumbwheel surface, and the second through hole 302 extends along the second direction.

[0064] In some embodiments, Figure 5 As shown, the conveyor body 300 further includes a second sleeve rod 330, which passes through the second through hole 302, connects the second thumbwheel 321 with the conveyor rod assembly 200, and is configured to make the conveyor rod assembly 200 rotate synchronously with the second thumbwheel 321. In response to the counterclockwise rotation of the second thumbwheel 321 around the second direction, at least a portion of the conveyor rod assembly 200 moves backward in the first direction, driving the connecting rod assembly 150 to move so that the mounting member 140 rotates counterclockwise around the third direction, thereby achieving the change in the rotation of the mounting member 140 to change the installation direction of the clamping member 500 on the mounting member 140.

[0065] In some embodiments, the delivery rod assembly 200 further includes a second sleeve 222, the second sleeve 222 is sleeved outside the first sleeve 221, and the second sleeve 222 and the first sleeve 221 can move relative to each other in the first direction. Both ends of the second sleeve 222 are respectively connected to the connecting rod assembly 150 and the second sleeve rod 330, and are configured to move synchronously with the second sleeve rod 330 to control at least a portion of the clamp assembly 100 to rotate around the third direction.

[0066] Specifically, a limited space 301 is provided inside the conveyor body 300, and a limited block 230 is provided at one end of the second sleeve 222 away from the clamp assembly 100, and the limited block 230 is slidably provided in the limited space 301. The two ends of the second sleeve rod 330 are respectively movably connected with the limited block 230 and the second thumbwheel 321. In response to the second thumbwheel 321 rotating clockwise around the second direction under the action of an external force, the limited block 230 drives the second sleeve 222 to move backward along the first direction. Since the end of the second sleeve 222 away from the second thumbwheel 321 module 320 is connected to the connecting rod assembly 150, in response to the second thumbwheel 321 rotating counterclockwise around the second direction, the second sleeve 222 moves backward in the first direction, driving the connecting rod assembly 150 to move so that the mounting member 140 rotates counterclockwise around the third direction, thereby achieving the change of the clamping direction of the mounting member 140 on the anastomotic opening.

[0067] In some embodiments, the conveyor 1000 further includes a clamping member 500, such as Figure 7As shown, the clamping member 500 is detachably disposed on the mounting portion 143 of the mounting member 140, and is configured to clamp the anastomosis under the clamping action of the clamp assembly 100. The projection size of the clamping member 500 in the third direction matches the mounting size of the mounting portion 143, so that the clamping member 500 can be installed in the mounting portions 143 of the first mounting member 141 and the second mounting member 142. Furthermore, the clamping member 500 moves synchronously with the mounting member 140.

[0068] The clamping member 500 includes: a clamping arm 510 and a fastener 520. The clamping arms 510 are arranged in pairs and are used to clamp the anastomosis. The fastener 520 is arranged in the middle of the clamping arm 510 and is perpendicular to the clamping arm 510 so that the two ends of the clamping arm 510 are evenly stressed. The fastener 520 is configured to adjust the spacing between the clamping arms 510. When an external force acts on the fastener 520, the two clamping arms 510 are close to each other to clamp the anastomosis.

[0069] It should be noted that the present disclosure does not specifically limit the shape structure of the clamp 500 . Regardless of the shape structure of the clamp 500 , the mounting portion 143 of the mounting member 140 matches the shape structure of the clamp 500 , so that the clamp 500 rotates synchronously with the mounting member 140 .

[0070] In some embodiments, the fastener 520 undergoes plastic deformation under the action of external force. In response to the clamp assembly 100 switching from the natural state to the clamped state, the fastener 520 undergoes plastic deformation, that is, the two clamping arms 510 work together to clamp the anastomosis to prevent leakage and bleeding of the anastomosis.

[0071] In some embodiments, the conveyor 1000 further includes a patch, which is disposed on the clamping arm 510 and is used to contact human tissue. In practical applications, leakage and bleeding of anastomotic tissue may not be completely avoided simply by clamping the clamp 500. This is because the clamp 500 is a rigid structure and cannot fully match the flexibility of soft tissue, resulting in leakage and bleeding in the nail hole. In addition, due to differences in soft tissue properties in different regions, some soft tissues, such as lungs, have lower strength and may be at risk of anastomotic tearing. To solve the above problems, the patch can be used in conjunction with the clamp 500, so that the clamp 500 clamps the anastomosis while the patch is fixed to the wound surface, thereby improving the clamping strength of the anastomosis and avoiding leakage and bleeding of the anastomosis.

[0072] In some embodiments, the clamp 500 may be a titanium metal element, which has a small rejection reaction with the human body and is similar to the elastic modulus of natural human bone, which can reduce the stress shielding effect, has better biocompatibility, and is more conducive to the growth and healing of human bones. On the other hand, the density of general titanium alloys is only slightly lower than that of stainless steel, which greatly reduces the load on the human body after being implanted into the human body.

[0073] The specific structure, working principle, and beneficial effects of the conveyor provided in the embodiments of the present disclosure may refer to the conveyor described in any of the above embodiments, and will not be elaborated here.
