DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] It should be understood that the terms "proximal" and "distal" used herein are relative to the clinician who manipulates the handle of the stapler. The term "proximal" refers to the part close to the clinician, and the term "distal" refers to the part away from the clinician. That is, the handle is the proximal side, and the jaw assembly is the distal side. For example, the proximal end of a component represents the end relatively close to the handle, and the distal end represents the end relatively close to the jaw assembly. The terms "upper" and "lower" are based on the relative positions of the anvil and the staple magazine seat of the jaw assembly. Specifically, the anvil is at the "upper" and the staple magazine seat is at the "lower". However, the stapler can be used in many directions and positions, so these terms expressing relative positional relationships are not restrictive and absolute.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms such as "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movable connection, or an integral body, or a transmission connection; it can be directly connected, or indirectly connected or transmitted through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements such as abutment. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. It should be noted that when there are qualifiers before "connected" and "connection", they have the meaning defined by the corresponding qualifiers, and only exclude situations that obviously need to be excluded, and do not exclude other possible situations. For example, "detachably connected" refers to a detachable connection, not including integration, but movable connection, etc. are not excluded. Example 1

[0029] This embodiment discloses a stapler assembly, such as Figure 1 and Figure 2 As shown, the stapler assembly is contained in the packaging box 200, including the stapler 100, accessories and the connector 300, the connector 300 is connected to the accessories, and the connector 300 is connected to the stapler 100, so that the accessories are connected to the stapler 100. The stapler assembly connects the accessories to the stapler 100 through the connector 300, and the medical staff takes out the stapler assembly from the packaging box 200, that is, takes out the stapler 100 and the accessories at the same time, so as to avoid the accessories being left out in the packaging box 200, and prompts the medical staff to use the accessories, and the medical staff can use the accessories in time when they need to use the accessories. After the stapler assembly is taken out, in response to the user's operation, the accessories are separated from the stapler 100, so that the accessories are removed from the stapler 100, the stapler 100 can be used independently, and the medical staff can use the accessories at any time.

[0030] The stapler 100 includes an operating assembly 130, a sleeve assembly 120 and a jaw assembly 110. One end of the sleeve assembly 120 is connected to the operating assembly 130, and the other end is connected to the jaw assembly 110. Figure 3 and Figure 4 As shown, the jaw assembly 110 includes a staple cartridge seat 111 and an anvil seat 112. The jaw assembly 110 in the packaging box 200 is in an open state, and the anvil seat 112 is arranged at an angle to the staple cartridge seat 111. The stapler 100 includes a mating portion 150, and a connector is connected to the mating portion 150 to achieve connection with the stapler 100, wherein the mating portion 150 includes one of the sleeve assembly 120, the staple cartridge seat 111, and the anvil seat 112.

[0031] Among them Figure 1 and Figure 3As shown, the connector 300 includes a connecting sleeve 310, a receiving space 330 is formed in the connecting sleeve 310, the connecting sleeve 310 is movably sleeved on the matching portion 150, at least a portion of the matching portion 150 is located in the receiving space 330, and at least a portion of the accessory is located in the receiving space 330, the matching portion 150 and the accessory are both abutted against the inner wall of the connecting sleeve 310, and the accessory is abutted against the matching portion 150. It can be seen that the accessory is abutted against the connecting sleeve 310 and the matching portion 150, and can be stably accommodated in the receiving space 330, and the accessory will not move relative to the connecting sleeve 310 and the matching portion 150, so that the accessory is connected to the stapler 100 through the connecting sleeve 310. The connecting sleeve 310 is movably mounted on the matching portion 150 so that the connecting sleeve 310 and the matching portion 150 can slide relative to each other. When disassembling the accessories, the user moves the connecting sleeve 310 distally (towards the side away from the operating portion), and the connecting sleeve 310 is separated from the matching portion 150, thereby separating the connecting piece 300 from the anastomosis device 100, so that the connecting piece 300 is removed, and the accessories are also removed for use by medical staff.

[0032] In a preferred embodiment, the matching portion 150 includes a nail magazine seat 111, and the nail magazine seat 111 has a first side facing the nail support seat 112 and a second side away from the nail support seat 112, the first side is attached to the inner wall of the connecting sleeve 310, and the second side is in contact with the accessory. The second side of the nail magazine seat 111 is generally flat, and the contact area between the accessory and the second side is large, so that the positions of the nail magazine seat 111 and the accessory in the receiving space 330 are relatively stable, and the connecting sleeve 310 only accommodates part of the nail magazine seat 111 and part of the accessories, so that the connecting sleeve 310 is small in size, and the connecting sleeve 310 is easier to slide relative to the nail magazine seat 111 to be removed.

[0033] Further, such as Figure 3 and Figure 5 As shown, the connecting member 300 further includes a baffle 320, which is connected to the connecting sleeve 310. The baffle 320 is disposed on the proximal side of the connecting sleeve 310 and abuts against the anvil 112. The anvil 112 includes an anvil 1121 and stoppers 1122 disposed on both sides of the anvil 1121. The stoppers 1122 are disposed on the proximal side of the anvil 1121. The nail magazine seat 111 includes a mating surface 1111, and the stoppers 1122 are located outside the mating surface 1111.

[0034] When the jaw assembly 110 is in the open state, there may be a first gap 140 between the stopper 1122 and the mating surface 1111. When the connecting sleeve 310 is installed, the side of the connecting member 300 with the baffle 320 is located on the proximal side of the connecting sleeve 310. The connecting sleeve 310 is sleeved outside the staple cartridge seat 111 and moved proximally. When the baffle 320 is close to the stopper 1122, it abuts against the staple cartridge seat 112. Specifically, the lower edge of the baffle 320 (the edge of one side away from the staple cartridge seat 111) abuts against the nail anvil 1121 to prevent the connecting sleeve 310 from continuing to move proximally. At this time, the connecting sleeve 310 is installed. The setting of the baffle 320 prevents the connecting sleeve 310 from excessively moving proximally, so that the wall of the connecting sleeve 310 enters the first gap 140, resulting in damage to the connecting sleeve 310 or difficulty in removal, or even the connecting sleeve 310 is broken, and part of it remains in the first gap 140, affecting the normal use of the stapler 100.

[0035] In this embodiment, the accessory is a nail magazine clamp 400, which includes a main body 410, a protrusion 420, a clamping structure and a holding structure. The main body 410 has a first area and a second area. The clamping structure is located in the first area, and the holding structure is located in the second area. The clamping structure is used to clamp the front end of the nail magazine assembly to lock the nail magazine assembly. The holding structure is used to work with the clamping structure when operated to remove the nail magazine assembly locked by the clamping structure from the nail magazine frame. The specific structure and operation method of the nail magazine clamp 400 can be found in the applicant's prior application CN202210455468.4, which will not be repeated in this application.

[0036] After the operation is completed, the medical staff needs to remove the staple cartridge assembly from the staple cartridge seat 111. The medical staff can quickly and safely remove the staple cartridge assembly from the staple cartridge seat 111 through the staple cartridge clip 400. When the medical staff takes out the stapler assembly, the stapler clip 400 is detachably connected to the stapler 100 through the connecting piece 300, that is, the medical staff takes out the stapler 100, the stapler clip 400 and the connecting piece 300 at the same time, so as to avoid leaving the stapler clip 400 in the packaging box 200, and remind the medical staff to use the stapler clip 400, so as to avoid the risk of the medical staff directly disassembling the staple cartridge assembly by hand.

[0037] The stapler 100 in the present application includes a knife pusher assembly (not shown in the figure), which includes a knife rod and a pusher connected to the knife rod. The pusher is used to push the knife pusher plate of the stapler assembly, that is, the stapler assembly used in the stapler 100 in the present application is a knife pusher assembly, and the knife pusher plate includes a nail pusher plate body and a cutting knife movably connected to the nail pusher plate body. When the pusher is separated from the knife pusher plate, the cutting knife is hidden in the nail pusher plate body. When the knife pusher assembly moves distally to cooperate with the knife pusher plate, the pusher acts on the cutting knife to move the cutting knife and expose it from the nail pusher plate body, so that the tissue can be cut. During the knife feeding process, the pusher pushes the knife pusher plate to move distally of the stapler assembly. When the knife feeding is completed, the knife pusher plate is located at the distal side of the stapler assembly. The knife retraction assembly moves proximally, and the pusher is separated from the knife pusher plate and retracts proximally to the initial position. The knife pusher plate remains at the distal side of the stapler assembly. At this time, the nail pushing plate with a knife is separated from the pusher, and the cutting knife is retracted and hidden in the nail pushing plate body. If the cutting knife is stuck and still exposed outside the nail pushing plate body, the cutting knife is exposed at the far side of the nail magazine assembly. If the nail magazine clamp 400 is not used to disassemble the nail magazine assembly, there may be a risk of injury to medical staff. In the stapler assembly of the present application, the medical staff takes out the stapler clamp 400 at the same time when taking out the stapler 100, prompting the medical staff to use the stapler clamp 400 to avoid the risk of medical staff directly disassembling the stapler assembly by hand.

[0038] The protrusion 420 is specifically a locking control member 421, which is movably disposed on the body 410. After the staple cartridge assembly is removed, the locking control member 421 is still clamped and locked by the body 410. When the locking control member 421 is operated, the body 410 releases the staple cartridge assembly. When the connector 300 is connected to the staple cartridge gripper 400, at least a portion of the body 410 is located in the receiving space 330 to abut against the mating portion 150.

[0039] The connecting sleeve 310 is provided with a through hole 311, and the protrusion 420 passes through the through hole 311 and is located outside the connecting sleeve 310. The side wall of the through hole 311 surrounds the protrusion 420 to prevent the staple cartridge clip 400 from moving relative to the connecting sleeve 310, and prevents the staple cartridge clip 400 from being separated from the connecting sleeve 310. Preferably, the through hole 311 is provided on the upper side of the connecting sleeve 310, and the protrusion 420 is located on the upper side of the main body 410 and passes through the through hole 311. The staple cartridge seat 111 abuts against the main body 410, so that the protrusion 420 is located outside the connecting sleeve 310. The side wall of the through hole 311 surrounds the bottom of the protrusion 420 to limit the lateral movement of the staple cartridge clip 400; the staple cartridge seat 111 abuts against the main body 410 to limit the longitudinal movement of the staple cartridge clip 400, so that the staple cartridge clip 400 is stably connected to the connecting sleeve 310.

[0040] When installing the connecting sleeve 310, Figure 6As shown, first, the protrusion 420 of the nail magazine gripper 400 is passed through the through hole 311 to connect the nail magazine gripper 400 with the connecting sleeve 310, and then the connecting sleeve 310 is sleeved on the nail magazine seat 111 and moved proximally until the baffle 320 abuts against the nail anvil 1121, so that the nail magazine gripper 400 is connected to the nail magazine seat 111. When removing the connecting sleeve 310 and the accessories, the connecting sleeve 310 is held and moved away from the sleeve assembly 120. Since the protrusion 420 is located in the through hole 311, the proximal side wall of the through hole 311 abuts against the protrusion 420, so that the connecting sleeve 310 moves distally with the nail magazine gripper 400. After the connecting sleeve 310 is separated from the nail magazine seat 111, the lower side of the main body 410 is no longer supported by the nail magazine seat 111, the nail magazine clamp 400 falls in the connecting sleeve 310, and the protrusion 420 enters the connecting sleeve 310, and the medical staff can take the nail magazine clamp 400 out of the connecting sleeve 310.

[0041] In another embodiment, Figure 7 and Figure 8 As shown, the accessories include a knife-retracting tool 500. The stapler 100 has a transmission assembly, and the transmission assembly is used to drive the propeller to retract the knife. When the transmission assembly is stuck, the knife retraction cannot be completed normally. The medical staff can use the knife-retracting tool 500 to manually drive the transmission assembly to retract the knife. The knife-retracting tool 500 is detachably connected to the stapler 100 through the connecting piece 300. The medical staff takes out the knife-retracting tool 500 at the same time when taking out the stapler assembly, so as to avoid the medical staff from forgetting the knife-retracting tool 500 in the packaging box 200, and remind the medical staff to use the knife-retracting tool 500.

[0042] In this embodiment, the knife-returning tool 500 includes a handle 510, a driving rod 530 and a nail-removing structure, the handle 510 has a first end and a second end opposite to the first end, the driving rod 530 is connected to the first end, the driving rod 530 cooperates with the transmission assembly of the stapler 100 to drive the transmission assembly to retreat, the nail-removing structure is connected to the second end, and the knife-returning tool 500 has both a nail-removing function and a knife-returning function. The specific structure of the knife-returning tool 500 can be found in the applicant's prior application CN2023106537993. The handle 510 of the knife-returning tool 500 is long and strip-shaped, and the driving rod 530 is rotatably connected to the first end of the handle 510 and is accommodated in the handle 510. When the driving rod 530 needs to be used, the medical staff can rotate the driving rod 530 relative to the handle 510 to expose the driving rod 530. When the connecting piece 300 is connected to the knife-returning tool 500, the driving rod 530 is accommodated in the handle 510, and at least a part of the handle 510 of the knife-returning tool 500 is located in the accommodating space 330 to abut against the matching part 150, so that the knife-returning tool 500 can be detachably connected to the stapler 100.

[0043] Furthermore, the nail removal structure includes a protective protrusion 520 protruding from the handle 510. The protective protrusion 520 is the part for the operator to apply force with his fingers. When the operator applies force, the thumb presses the protective protrusion 520, thereby completely avoiding the nail magazine assembly, thereby avoiding finger injuries and improving the safety of the knife return tool 500. The connection method of the knife return tool 500 and the connecting sleeve 310 is roughly the same as the connection method of the nail magazine clamp 400 and the connecting sleeve 310. The connecting sleeve 310 is provided with a through hole 311, and the protective protrusion 520 passes through and is located outside the connecting sleeve 310. The side wall of the connecting hole 311 surrounds the protective protrusion 520, blocking the knife return tool 500 from moving relative to the connecting sleeve 310, and preventing the knife return tool 500 from detaching from the connecting sleeve 310. Preferably, the through hole 311 is opened on the upper side of the connecting sleeve 310 , the protective protrusion 520 is located on the upper side of the handle 510 and passes through the through hole 311 , and the nail magazine seat 111 abuts against the handle 510 so that the protective protrusion 520 is located outside the connecting sleeve 310 .

[0044] When installing the connecting sleeve 310, firstly, the protective protrusion 520 of the knife-returning tool 500 is passed through the through hole 311, the knife-returning tool 500 is connected to the connecting sleeve 310, and then the connecting sleeve 310 is sleeved on the nail magazine seat 111, and the connecting sleeve 310 is moved proximally until the baffle 320 abuts against the nail anvil 1121, so that the knife-returning tool 500 is connected to the nail magazine seat 111. When removing the connecting sleeve 310 and the accessories, hold the connecting sleeve 310 and move the connecting sleeve 310 away from the sleeve assembly 120. Since the protective protrusion 520 is located in the through hole 311, the connecting sleeve 310 will move the knife-returning tool 500 to the distal side. After the connecting sleeve 310 is separated from the nail magazine seat 111, the handle 510 of the knife-returning tool 500 no longer abuts against the nail magazine seat 111, the knife-returning tool 500 falls in the connecting sleeve 310, and the protective protrusion 520 enters the connecting sleeve 310, and the medical staff can take the knife-returning tool 500 out of the connecting sleeve 310. Example 2

[0045] The second embodiment of the present application discloses a stapler assembly, which is substantially the same as the first embodiment, except that: Fig. 9 and Fig.10As shown, the connector 300 includes a double-headed connector 340, and the double-headed connector 340 has a first part 341 and a second part 342. The first part 341 is detachably connected to the matching part 150, and the second part 342 is detachably connected to the accessory. The double-headed connector 340 is detachably connected to the accessory and the matching part 150 at the same time, so that the accessory is detachably connected to the stapler 100. When the stapler assembly is taken out, the stapler 100 and the accessory can be taken out at the same time to avoid the accessory being omitted, and the user is prompted to use the accessory. In response to the user's operation, the double-headed connector 340 is removed from the stapler 100, and the accessory is removed from the double-headed connector 340, so that the accessory is separated from the stapler 100, the stapler 100 can be used independently, and the medical staff can use the accessory at any time.

[0046] The accessories in this embodiment include a nail magazine clamp 400 or a knife return tool 500. Preferably, the mating portion 150 includes a sleeve assembly 120. The first portion 341 of the double-headed connector 340 is provided with a snap ring 3411, and the snap ring 3411 is snapped with the sleeve assembly 120. The sleeve assembly 120 is arranged in a cylindrical shape. The snap ring 3411 is a cylindrical clamping arm with an opening at one end. The cross section of the snap ring 3411 is an arc with an opening. The central angle of the arc is greater than 180°. The opening width of the snap ring 3411 is smaller than the outer diameter of the sleeve assembly 120, and the snap ring 3411 has a certain elastic force. When installing the snap ring 3411 to the sleeve assembly 120, align the opening of the snap ring 3411 with the sleeve assembly 120 and install it in the radial direction. In the radial direction, the width of the sleeve assembly 120 increases first and then decreases. The maximum width of the sleeve assembly 120 is equal to its outer diameter. Since the opening width of the clamp ring 3411 is smaller than the outer diameter of the sleeve assembly 120, the clamp ring 3411 is blocked by the maximum width portion of the sleeve assembly 120. The double-headed connector 340 is pressed hard to cause the clamp ring 3411 to undergo elastic deformation, increase the opening width, and allow the maximum width portion of the sleeve assembly 120 to enter the opening and enter the clamp ring 3411. After passing through the maximum width portion of the sleeve assembly 120, the clamp ring 3411 returns to its original shape or maintains a certain degree of elastic deformation under its own elastic force, covering most of the sleeve assembly 120 to achieve clamping with the sleeve assembly 120. Only when the user applies a certain amount of force to the clamp ring 3411 can the clamp ring 3411 be separated from the sleeve assembly 120, and the double-headed connector 340 can be removed from the stapler 100.

[0047] The second part 342 of the double-headed connector 340 is provided with a fixing sleeve 3421, which is sleeved on the accessory, and the accessory abuts against the inner wall of the fixing sleeve 3421 to be fixed in the fixing sleeve 3421. The fixing sleeve 3421 is connected to the snap ring 3411. Preferably, the fixing sleeve 3421 and the snap ring 3411 in this embodiment are integrally formed. The fixing sleeve 3421 is set in a sleeve shape, and its cross section is generally square. When the nail magazine clamp 400 cooperates with the fixing sleeve 3421, its body 410 is inserted into the fixing sleeve 3421, specifically, the gripping structure is inserted into the fixing sleeve 3421, and the height of the gripping structure gradually increases in the direction close to the gripping structure, that is, during the process of inserting the gripping structure into the fixing sleeve 3421, the height of the gripping structure is smaller than the height of the fixing sleeve 3421 at the beginning, and as the insertion proceeds, the height of the part of the gripping structure located in the fixing sleeve 3421 increases until both sides of the gripping structure in the height direction abut against the fixing sleeve 3421, thereby fixing the nail magazine clamp 400 in the fixing sleeve 3421. Similarly, the handle 510 of the knife return tool 500 is generally the same in structure as the body 410 of the nail magazine clamp 400, and the method of fixing it in the fixing sleeve 3421 is the same, which will not be repeated in this embodiment.

[0048] When installing the stapler clip 400 or the knife return tool 500 on the stapler 100 through the double-headed connector 340, first insert the stapler clip 400 or the knife return tool 500 into the fixing sleeve 3421 to achieve a detachable connection between the stapler clip 400 or the knife return tool 500 and the double-headed connector 340; then, the clamp ring 3411 is clamped to the sleeve assembly 120 to achieve a detachable connection between the double-headed connector 340 and the stapler 100, thereby achieving a detachable connection between the stapler clip 400 or the knife return tool 500 and the stapler 100. When taking out the stapler 100 assembly, the stapler 100 and the accessories can be taken out at the same time.

[0049] In response to the user's operation, the accessory is separated from the stapler 100. The user's operation is: pull the clamping ring 3411 with a certain force to deform the clamping arm 3412. The opening of the clamping arm 3412 is larger than the outer diameter of the sleeve assembly 120, and the clamping ring 3411 can be separated from the sleeve assembly 120; then hold the fixing sleeve 3421 with one hand and the stapler magazine clamp 400 or the knife return tool 500 with the other hand, pull the stapler magazine clamp 400 or the knife return tool 500, and the pulling direction is opposite to the installation direction, so that the accessory is removed from the fixing sleeve 3421, completing the separation of the accessory from the stapler 100, and the stapler 100 and the accessory can be used independently. Example 3

[0050] The third embodiment of the present application discloses a stapler assembly, which is substantially the same as the first embodiment, except that: Fig.11 and Fig.12As shown, the connector 300 includes a connecting line 350, which is connected to the accessory and connected to the mating part. The connecting line 350 connects the accessory to the stapler 100. When the stapler assembly is taken out, the stapler 100 and the accessory can be taken out at the same time to avoid the accessory being missed, and the user is prompted to use the accessory. In response to the user's operation, the accessory is separated from the stapler 100, the stapler 100 can be used independently, and the medical staff can use the accessory at any time. The connecting line 350 can stably connect the stapler 100 and the accessory. When removing the accessory from the stapler 100, the user's operation is to destroy the connecting line 350, such as cutting the connecting line 350, so that the stapler 100 is separated from the accessory.

[0051] In a preferred embodiment, the connecting wire 350 is formed into a ring, the accessory is provided with a threading hole 440, the matching part includes a staple cartridge seat 111, and the bottom 3512 of the staple cartridge seat 111 is provided with a knife feed groove 1112, and the connecting wire 350 passes through the knife feed groove 1112 of the staple cartridge seat 111 and the threading hole 440 of the accessory, so that the accessory is connected to the staple cartridge seat 111. The accessory may be a staple cartridge clamp 400 or a knife return tool 500, and when the accessory is a staple cartridge clamp 400, the threading hole 440 is provided in the body 410; when the accessory is a knife return tool 500, the threading hole 440 is provided in the handle 510, and the connecting wire 350 formed into a ring sequentially connects the accessory and the stapler 100, so that the accessory and the stapler 100 are connected.

[0052] The connecting line 350 has a plug connector 351 at one end and a plug connector 352 at the other end. Fig.12As shown, the plug connector 351 can be plugged and connected with the plug part 352, so that the connecting wire 350 is surrounded by a ring. When the accessory is installed on the stapler 100, the plug connector 351 and the plug part 352 are separated, and one end of the connecting wire 350 is held and passed through the knife feed groove 1112 of the stapler seat 111 and the threading hole 440 of the accessory in sequence, and then the plug connector 351 is plugged with the plug part 352, and the connecting wire 350 is surrounded by a ring, so that the accessory is connected to the stapler 100. The plug connector 351 is conical in shape, having a tip portion 3511 and a bottom portion 3512, wherein the width of the bottom portion 3512 is greater than that of the tip portion 3511; the plug connector 352 includes a plug hole 3521, wherein a blocking portion (not shown in the figure) is disposed in the plug hole 3521, wherein the blocking portion extends radially along the plug hole 3521 and has a certain elasticity, and is used to block the bottom portion 3512 of the plug connector 351; when the plug connector 351 is mated with the plug connector 352, the tip portion 3511 is firstly passed into the plug hole 3521, and the blocking portion is deformed through the conical side wall of the plug connector 351 so that the entire plug connector 351 passes through the blocking portion, thereby completing the plug-in connection between the plug connector 351 and the plug connector 352. When the plug connector 351 tends to be separated from the plug hole 3521, the blocking portion abuts against the bottom 3512 of the plug connector 351, preventing the plug connector 351 from being separated from the plug portion 352, so that the two ends of the connecting line 350 cannot be separated, and the connecting line 350 can be stably maintained in a ring state.
