[0119] Embodiment 1

[0120] like Figure 3 As shown, the present invention provides an ultra-thin rod laparoscope assembly, including an adapter sleeve assembly 101, an intermediate sleeve assembly 102 installed on the adapter sleeve assembly 101, a nail support assembly 103 and a nail magazine assembly 105 movably installed on the intermediate sleeve assembly 102 through a clamp head seat assembly 104.

[0121] Among them, the pushing component and the steering hook pass through the connecting sleeve component 101 and the middle sleeve component 102. The pushing component can push the cutting knife component 1021 forward and backward, and the steering hook can drive the nail support assembly 103 to turn; the pushing component can drive the nail support assembly 103 to close to the nail magazine assembly 105 to press the nails, and at the same time the cutting knife climbs the slope to cut the tissue.

[0122] The prior art discloses a laparoscope assembly with an 8mm diameter. However, since the laparoscope assembly is too thin, the internal actuators are prone to displacement or distortion during use, which causes errors in the operation of the laparoscope assembly and easily leads to errors in surgical operations. In order to avoid the above errors, the present device adjusts the internal structure of the laparoscope assembly to better adapt to the movement or rotation of the thin components, thereby avoiding errors caused by instrument errors during surgery.

[0123] Please focus on Figure 4-5 The adapter sleeve assembly 101 includes a sleeve, and an outer sleeve 1011 sleeved outside the sleeve, a transmission rod 1017 and a secondary safety assembly 1018 placed in the sleeve, a steering hook 1016 and a pressure strip 1019 placed on the sleeve, a safety 1012 sleeved outside the sleeve, the safety 1012 is used to lock the secondary safety assembly 1018 to avoid accidental activation of the secondary safety assembly 1018, and a connecting rod joint 1013 installed at one end of the sleeve, wherein the transmission rod 1017 is installed on the secondary safety assembly 1018.

[0124] When the pushing component needs to be opened, the safety 1012 needs to be turned off first, and then the secondary safety component 1018 is pushed, and the movement range of the pushing component is limited by the secondary safety component 1018.

[0125] The sleeve includes a connecting rod 1014 and a cover plate 1015. Please refer to Figure 8 and Fig.17 , the steering hook 1016 and the pressure strip 1019 are placed on the connecting rod 1014. Please refer to Figure 6 The connecting rod 1014 is provided with a buckle position 10143 and a plurality of bosses 3 10144, one end of the cover plate 1015 fits the buckle position 10143, and the cover plate 1015 is provided with a groove 5 that fits the bosses 3 10144. The cover plate 1015 is mounted on the connecting rod 1014.

[0126] Please focus on Figure 7-9 The connecting rod joint 1013 is symmetrically provided with buckles 10131, and a notch 10132 is provided on one side of the connecting rod joint 1013, and a side convex seat 10133 is provided on the other side of the connecting rod joint 1013. A clamping hole 10141 is provided at a position corresponding to the buckle 10131 on the connecting rod 1014, and a track 10145 is provided at a position corresponding to the side convex seat 10133 on the connecting rod 1014. The buckle 10131 is clamped in the clamping hole 10141, the steering hook 1016 is placed in the notch 10132, and the side convex seat 10133 is placed in the track 10145.

[0127] In order to match the overall slimness of the device, the steering hook 1016 tends to be slimmer. When the steering dowel assembly 103 needs to be turned, the steering hook 1016 will be pulled, so that the steering hook 1016 needs to be prevented from being offset or twisted when moving.

[0128] The connecting rod joint 1013 is made of elastic material, such as nylon; when the buckle 10131 of the connecting rod joint 1013 is installed in the clamping hole 10141, the notch 10132 is reduced, thereby clamping the steering hook 1016 placed in the notch 10132, thereby preventing the notch 10132 from being too large and the steering hook 1016 from being too thin, which causes the steering hook 1016 to shake back and forth in the notch 10132 when moving; at the same time, since the steering hook 1016 on one side is pulled when the steering hook is started, and the existing steering hook 1016 is too thin, there will be an imbalance on the other side, causing the connecting rod joint 1013 to deviate, thereby driving the steering hook 1016 to deviate, so the side boss 10133 is designed to avoid the shaking of the connecting rod joint 1013, thereby avoiding the deviation of the steering hook 1016.

[0129] Please focus on Figure 10-12 A block 10121 is provided on the inner wall of the safety 1012, and a slot 10181 is provided at the position of the secondary safety assembly 1018 corresponding to the block 10121. At the same time, a slide slot 10142 is provided on the connecting rod 1014, and the block 10121 passes through the slide slot 10142 and is placed in the slot 10181. When installing, the block 10121 is located in the slot 10181, so as to prevent the staff from starting the device by mistake. When the safety 1012 is rotated, the block 10121 moves along the slide slot 10142 to stagger the slot 10181, so as to start pushing the secondary safety assembly 1018.

[0130] Please focus on Figure 13-15 The secondary safety assembly 1018 includes a connecting base 10182, a connecting sleeve 10183 clamped in the connecting base 10182, a secondary safety 10184 placed in the connecting base 10182 and hinged on the connecting sleeve 10183 through a hinge shaft 10186, and the secondary safety 10184 is connected to the hinge shaft 10186 through a torsion spring 10185, and the torsion spring 10185 gives the secondary safety 10184 a downward force, and a boss 10152 is symmetrically provided on the inner wall of the cover plate 1015, and a limiting groove 10151 is provided on the bottom of the cover plate 1015.

[0131] During installation, the secondary fuse 10184 is placed on the boss 10152. When the secondary fuse assembly 1018 is pushed, the secondary fuse 10184 moves along the boss 10152. Please pay attention to Fig.16When the movement exceeds the position of the boss 10152, the secondary insurance component 1018 is reset, and the secondary insurance component 1018 is pulled back, and one end of the secondary insurance 10184 will fall into the limit groove 10151, thereby limiting the entire movement of the secondary insurance 10184 to move only within the limited range of the limit groove 10151 to prevent subsequent mis-activation. The limit groove 10151 is the safe distance for the secondary insurance component 1018 to move. Please also pay special attention to Fig.17 The pressure strip 1019 is located directly above the secondary safety component 1018 and can provide thrust when the secondary safety component 1018 is reset, further assisting the secondary safety component 1018 in resetting.

[0132] The device is provided with two safety devices. The first one is the design of safety device 1012. Safety device 1012 needs to be opened before starting the operation. The second one is the design of secondary safety component 1018. A safety distance is designed for the whole operation, which avoids surgical errors caused by instruments to the greatest extent.

[0133] Please focus on Figure 18-19 A second buckle position 101711 is symmetrically provided at one end of the transmission rod 1017, and the second buckle position 10171 is L-shaped, and a low-position slot 10172 is provided at the end of the second buckle position 10171 away from the end face of the transmission rod 1017, and the end face of the low-position slot 10172 is lower than the end face of the second buckle position 10171, and the block end connected to the base 10182 moves along the second buckle position 10171, and then the transmission rod 1017 is rotated, and the block end is inserted into the low-position slot 10172, and at this time, the transmission rod 1017 is fixed on the secondary insurance component 1018.

[0134] Since the transmission rod 1017 is long enough and too thin, in order to avoid the transmission rod 1017 from being offset or twisted when pushing the secondary safety component 1018, a low-level slot 10172 is designed. Since the low-level slot 10172 is lower than the second buckle position 10171, the transmission rod 1017 will be completely and firmly connected to the secondary safety component 1018, thereby preventing the transmission rod 1017 from falling off the secondary safety component 1018.

[0154] Please focus on Fig.38 In the prior art, a relatively large gap is reserved between the staple holder assembly and the staple cartridge assembly in consideration of the conventional components having a certain thickness, and this area is the triangular area 107; however, during operation, the tissue in the triangular area 107 cannot be effectively squeezed, and excessive tissue tension is likely to exist. When the tissue is to be cut, the tissue will slip, causing the cutter to move to the middle position of the staple holder assembly, resulting in tissue accumulation, which is likely to cause tearing and pulling in subsequent operations, resulting in rupture of the staple holes and leading to surgical accidents.

[0155] Please focus on Fig.39 In order to overcome the problem of the triangular area 107, the end surface of the staple cartridge assembly 105 in the present device is set to be flat, without a slope, to avoid the formation of the triangular area 107; however, the above design is prone to excessive squeezing of tissues during the operation, especially at the end of the entire assembly. In order to avoid the above excessive squeezing, please focus on Fig.42 A protrusion 1055 is provided on the end surface of the nail magazine assembly 105, so as to ensure that there is always a gap when the pushing assembly drives the nail support assembly 103 to be pressed against the nail magazine assembly 105.

[0156] Please focus on Figure 40-41 The anvil assembly 103 includes an anvil 1032, an eagle hook 1034 installed at one end of the anvil 1032, a slot 1035 is provided inside the anvil 1032, one end of the cutting knife assembly 1021 passes through the anvil 1032 and is located in the slot 1035, and an anvil cover 1033 is covered above the slide slot.

[0157] Please focus on Figure 42-43 The nail magazine assembly 105 includes a nail magazine 1051 and a nail magazine bracket 1052, a nail pushing piece 1054 and an oblique pushing block 1053 disposed inside the nail magazine 1051, and the other end of the cutting knife assembly 1021 passes through the second slot 10516 provided on the nail magazine 1051 and the third slot 10525 provided on the nail magazine bracket 1052 in sequence.

[0158] Please focus on Fig.44 and Fig.49Since the overall component design is more slender, the parts containing the notches are easily squeezed. When the cutting knife moves along the notches, the other parts of the notches are easily subjected to inward pressure, i.e., squeezing force is generated, thereby causing the parts containing the notches to twist and deform, i.e., the nail groove 10515 on the nail support 1032 is not aligned with the nail magazine hole on the nail magazine 1051, thereby affecting the forming of the anastomotic staples; wherein the notches include notch one 1035, notch two 10516 and notch three 10525.

[0159] Please focus on Fig.45 and 46 In order to solve the above problems, the nail magazine 1051 is provided with a front buckle 10511, a middle buckle 10512, an inner groove and a rear buckle 10513, and the nail magazine bracket 1052 is provided with a hole position 10522, a groove position 6 10521, a protrusion 3 10524 and a hole position 2 10523; wherein the front buckle 10511 is snapped into the hole position 10522, the rear buckle 10513 is snapped into the hole position 2 10523, the middle buckle 10512 is snapped into the groove 6 10521, and the protrusion 3 10524 is snapped into the inner groove; the purpose of the front buckle 10522 and the rear buckle 10513 is to prevent the nail magazine 1051 from moving upward during operation; the purpose of the middle buckle 10512 and the protrusion 3 10524 is to prevent the nail magazine 1051 from deforming and twisting due to the extrusion force.

[0160] At the same time, in order to position the tissue when the cutting knife 1021 is working and prevent the tissue from sliding, the nail magazine 1051 is evenly provided with a plurality of protrusions 10514 along the position of the second groove 10516.

[0161] Please focus on Fig.50 In order to prevent the nail magazine bracket 1052 from twisting and deforming due to the slot three 10525, a protrusion six 1056 is provided at the bottom of the oblique push block 1053. When the cutting knife assembly 1021 moves along the slot, the cutting knife assembly 1021 pushes the oblique push block 1053 forward, and the protrusion six 1056 serves as an extension of the cutting knife assembly 1021 in the slot three 10525, thereby increasing the force area at the slot three 10525 and reducing the deformation of the nail magazine bracket 1052.

[0162] Please focus on Fig.34 and 35 In order to prevent the nail seat 1032 from being twisted and deformed due to the slot 1035, an extension portion 10218 is provided at one end of the cutting knife 10217 in the slot 1035. The function of the extension portion 10218 is similar to that of the protrusion 1056, which increases the force area at the slot 1035 and reduces the deformation of the nail seat 1032.

[0163] At the same time, the nail magazine 1051 of the present device is symmetrically provided with three rows of nail grooves 10515, while the nail magazine in the prior art is only provided with two rows of nail grooves 10515. Since the present device is more slender, if the design of the nail grooves 10515 in the prior art is followed, please refer to the following. Fig.47 The nail magazine in the figure is the first improvement, which will cause the middle part of the nail slot 10515 to be easily twisted and deformed during operation; please refer to Fig.48 In order to solve the above problem, the groove wall on one side of the nail groove 10515 needs to be connected, so as to improve the structural strength of the nail magazine 1051 and prevent the nail groove 10515 from being deformed.

[0164] When the pushing assembly is working, the cutting knife assembly 1021 drives the nail support assembly 103 to close to the nail magazine assembly 105, and at the same time pushes the oblique pushing block 1053, and the oblique pushing block 1053 pushes the nail pushing piece 1054 to move upward, thereby stapling the tissue, and then the cutting knife 10217 cuts the tissue.

[0165] The design of the present device is to adapt to slimmer laparoscope components, to prevent the internal components of the laparoscope components from twisting or shifting due to their slim structure when operating, thereby avoiding surgical problems caused by instruments; secondly, in order to prevent misoperation, the present device is designed with two insurances for the push component, and a safe distance is designed for the entire operation, thus avoiding surgical errors caused by instruments to the greatest extent, and insurance is also designed for the steering retractor; finally, the present device is designed with an observation window 10110, which can observe at any time whether the instrument is activated, and can effectively solve the instrument activation problem.
