Description

Technical Field

[0001] This invention relates to a high-speed stapler mounting device for medical staplers, applicable to the field of stapler manufacturing technology. Background Technology

[0002] Medical staplers are medical devices used in medicine to replace traditional manual suturing. Their principle is similar to a stapler, using titanium staples to quickly and conveniently sever or anastomose tissue. There are many types of medical staplers available, but most consist of an activation handle, a rod connected to the activation handle at one end, and a staple cartridge at the other end of the rod. Currently, some staplers on the market have detachable staple cartridges, such as linear cutting staplers. In these cases, the pre-loaded staple cartridge needs to be installed into the front end of the stapler. However, for some circular staplers, such as disposable circular staplers suitable for rectal or esophageal anastomosis, the staple cartridge is cylindrical with several evenly distributed staple grooves around its axis on the front face. The staple cartridge is fixed to the other end of the rod. Therefore, these types of staplers usually require the titanium staples to be installed in the staple grooves during manufacturing so that users can use them immediately after unpacking. However, most current methods for installing titanium staples involve manual installation, which is not only inefficient, but also prone to contamination due to the fact that the stapler is a medical device that needs to be kept sterile and dust-free. In addition, since the staple cartridge usually needs to hold a dozen or so titanium staples, and the staples are small, manual installation is prone to omissions or misinstallation due to inattention or mistakes, which can affect the normal use of the stapler in the later stages. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes a high-speed stapler device for medical staplers.

[0004] The technical solution adopted in this invention is: a high-speed stapler for medical staplers, comprising: The feeding mechanism is used to transport titanium nails. The feeding mechanism includes a first feeding section and a second feeding section.

[0005] A positioning mechanism for fixing the stapler and transferring it to the processing position. The positioning mechanism includes a fixing seat for fixing the stapler in a staple cartridge-up orientation, a first drive unit connected below the fixing seat for driving the fixing seat to rotate about the axis of the staple cartridge, and a second drive unit for driving the fixing seat to move in the front-back direction and in the left-right direction.

[0006] A nailing mechanism is used to load titanium nails conveyed by a feeding mechanism into a nail magazine. The nailing mechanism includes a rotary joint that is rotatably disposed between a first feeding section and a second feeding section about a vertically arranged first rotating shaft; a third driving section for driving the rotary joint to rotate; a first swing arm and a second swing arm, one end of which are respectively fixedly connected to the rotary joint; and a first clamping section and a second clamping section respectively disposed at the other end of the first swing arm and the second swing arm for clamping and installing titanium nails. The nailing mechanism has at least two working states. When it is in the first working state, the first swing arm rotates to the discharge position of the first feeding section, and the first clamping section clamps the titanium nail located at the discharge position; the second swing arm rotates to the processing position, and the second clamping section loads the clamped titanium nail into the nail magazine. When the nailing mechanism is in the second working state, the first swing arm rotates to the processing position, and the first clamping section loads the clamped titanium nail into the nail magazine; the second swing arm rotates to the discharge position of the second feeding section, and the second clamping section clamps the titanium nail located at the discharge position. During production, the operator first fixes the stapler to be installed into the mounting base. Then, the second drive unit moves the stapler to the processing position. Subsequently, the titanium staples are simultaneously fed by the first and second feeding units. When the titanium staples are delivered to the discharge point, the third drive unit drives the rotary joint to rotate, causing the first and second swing arms to swing back and forth. This first puts the staple installation mechanism into the first working state, in which the first swing arm performs a clamping action to facilitate material removal, while the second swing arm performs an installation action to install the titanium staples. Then, the staple installation mechanism enters the second working state, in which the first swing arm performs the installation action, and the second swing arm simultaneously performs... The clamping action; during the switching of the working state of the stapler mechanism, the first drive unit will synchronously drive the fixed seat to rotate so that the empty staple slot on the staple cartridge always corresponds to the first clamping part or the second clamping part. By repeatedly switching the stapler mechanism between the first working state and the second working state, and cooperating with the first drive unit to rotate the fixed seat, the automatic stapler processing of the stapler is realized. This avoids the problems of low efficiency, easy contamination and easy error caused by manual stapler. Moreover, through the two feeding parts and the corresponding two swing arms and clamping parts, the time occupied by the processing gap is greatly reduced, which greatly improves the stapler processing speed and thus greatly improves the processing efficiency.

[0007] Furthermore, the fixing base is cylindrical, and the top of the fixing base has a fixing groove for the staple cartridge of the stapler to be engaged therein. The positioning mechanism also includes at least one limiting member for limiting the position of the stapler when it is engaged in the fixing groove. By engaging the stapler in the fixing groove and limiting and fixing its position by the limiting member, the fixing base can move the stapler to the processing position and control its rotation to facilitate staple loading.

[0008] Furthermore, the first driving unit includes a turntable fixedly connected to the bottom of the fixed base, and a first driver connected below the turntable for driving the turntable to rotate. The second driving unit includes a first slide rail arranged in the front-back direction, a first slide block slidably connected to the first slide rail, a second driver for driving the first slide block to slide, a second slide rail arranged in the left-right direction on the first slide block, a second slide block slidably connected to the second slide rail, and a third driver for driving the second slide block to slide. The first driver is fixedly connected to the second slide block. By driving the first slide block and the second slide block with the second driver and the third driver respectively, the fixed base can move in the front-back direction and the left-right direction. By driving the turntable with the first driver, the fixed base can rotate.

[0009] Furthermore, the first clamping part includes a third slide rail vertically disposed at the end of the first swing arm, a third slide block slidably connected to the third slide rail, and a pair of first grippers disposed at the lower end of the third slide block and capable of opening or clamping relative to each other. The second clamping part includes a fourth slide rail vertically disposed at the end of the second swing arm, a fourth slide block slidably connected to the fourth slide rail, and a pair of second grippers disposed at the lower end of the fourth slide block and capable of opening or clamping relative to each other. When the first swing arm and the second swing arm swing to the discharge position or processing position of the loading part, respectively, the first grippers and the second grippers move down synchronously along the third slide rail and the fourth slide rail, respectively, to facilitate the operation of clamping or installing titanium nails. After the operation is completed, the first grippers and the second grippers move up synchronously to switch working states.

[0010] Furthermore, the first clamping part also includes a first pressing component fixedly disposed on the third slide and used to press the titanium nail into the nail magazine, and the second clamping part also includes a second pressing component fixedly disposed on the fourth slide and used to press the titanium nail into the nail magazine. When the nailing mechanism is in the first working state, the position of the second gripper corresponds to the first nail groove, and the position of the second pressing component corresponds to the second nail groove located on one side of the first nail groove and adjacent to the first nail groove. When the nailing mechanism is in the second working state, the position of the first gripper corresponds to the third nail groove located on the other side of the first nail groove and adjacent to the first nail groove, and the position of the first pressing component corresponds to the first nail groove. It should be noted that the terms "first nail slot," "second nail slot," and "third nail slot" are used for ease of description and do not refer to any specific nail slot. In actual processing, nail slots are usually evenly distributed around the axis of the nail magazine. By setting the relative positions of the first and second pressing components, when the first or second gripper corresponds to the position of a nail slot for nailing, the first or second pressing component corresponds to the position of the adjacent nail slot. Furthermore, the first and second pressing components are set to move up and down synchronously with the first and second grippers, thereby facilitating the pressing of the titanium nail after it has been installed by the grippers, ensuring that the titanium nail can be installed in place and improving the nailing effect.

[0011] Furthermore, the first feeding section includes a first vibrating disc, a first feeding trough connected at one end to the first vibrating disc, and a first distributing disc rotatably disposed at the other end of the first feeding trough around a rotating shaft arranged along the traveling direction of the titanium nails in the first feeding trough. The side of the first distributing disc is evenly provided with a plurality of first receiving slots for accommodating titanium nails along its circumference. Each first receiving slot has a first position and a second position due to the rotation of the first distributing disc. When it is in the first position, the first receiving slot is connected to the other end of the first feeding trough. When the first receiving slot is in the second position, the first receiving slot is located at the discharge point of the first feeding section. When one first receiving slot is in the second position, the other first receiving slot is in the first position. The scattered titanium nails are conveyed one by one into the first feeding trough in the same and specific posture by the first vibrating plate. Then, by rotating the first distributing plate, the first receiving grooves opened on it are connected to the other end of the first feeding trough in sequence, so that the titanium nails conveyed to the other end of the first feeding trough are respectively included into several first receiving grooves, thereby separating the titanium nails individually, so that the first gripper can pick up the titanium nails from the first receiving groove.

[0012] Furthermore, the first feeding section also includes a first pneumatic pusher disposed on the side of the first feeding trough and used to push titanium nails into the first receiving trough. Each first receiving trough also has a third position located between the first position and the second position due to the rotation of the first distributing plate. When it is in the third position, the first receiving trough corresponds to the output end of the first pneumatic pusher. When one first receiving trough is in the second position, two other first receiving troughs are in the third position and the first position, respectively. Each first receiving trough will sequentially pass through the first position, the third position, and the second position as the first distributing plate rotates. In the first position, the first receiving trough receives the titanium nails conveyed from the first feeding trough, and then rotates to the third position so that the first pneumatic pusher can push the titanium nails to ensure that the titanium nails are completely in the first receiving trough. This avoids adverse effects on the gripping and installation of the first gripper due to the positional deviation of the titanium nails, and ensures the stability of the nailing process. After being pushed into place, the first receiving trough rotates to the second position so that the first gripper can grip the titanium nails from this position, thereby realizing the feeding of titanium nails.

[0013] Furthermore, the second feeding section includes a second vibrating disc, a second feeding trough connected at one end to the second vibrating disc, and a second distributing disc rotatably disposed at the other end of the second feeding trough around a rotating shaft arranged along the traveling direction of the titanium nails in the second feeding trough. The side of the second distributing disc is evenly provided with a plurality of second receiving slots for accommodating titanium nails along its circumference. Each second receiving slot has a first position and a second position due to the rotation of the second distributing disc. When it is in the first position, the second receiving slot is connected to the other end of the second feeding trough. When the second receiving slot is in the second position, the second receiving slot is located at the discharge point of the second feeding section. When one second receiving slot is in the second position, the other second receiving slot is in the first position. The scattered titanium nails are conveyed one by one into the second feeding trough in the same and specific posture by the second vibrating plate. Then, by rotating the second distributing plate, the second receiving slots opened on it are connected to the other end of the second feeding trough in sequence, so that the titanium nails conveyed to the other end of the second feeding trough are respectively included into several second receiving slots, thereby separating the titanium nails individually, so that the second gripper can pick up the titanium nails from the second receiving slots.

[0014] Furthermore, the second feeding section also includes a second pneumatic pusher disposed on the side of the second feeding trough and used to push titanium nails into the second receiving trough. Each second receiving trough also has a third position located between the first position and the second position due to the rotation of the second distributing plate. When it is in the third position, the output end of the second pneumatic pusher corresponds to the second receiving trough being in the second position, while the other two second receiving troughs are in the third position and the first position, respectively. Each second receiving trough will sequentially pass through the first position, the third position, and the second position as the second distributing plate rotates. In the first position, the second receiving trough receives the titanium nails conveyed from the second feeding trough, and then rotates to the third position so that the second pneumatic pusher can push the titanium nails, ensuring that the titanium nails are completely within the second receiving trough. This avoids adverse effects on the gripping and installation of the second clamping jaws due to titanium nail position deviation, ensuring the stability of the nailing process. After being pushed into place, the second receiving trough rotates back to the second position so that the second clamping jaws can grip the titanium nails from this position, thereby realizing the feeding of titanium nails.

[0015] Furthermore, the high-speed stapler also includes a visual inspection mechanism for detecting the position of the fixing seat. The visual inspection mechanism includes a bracket fixedly mounted above the stapler mechanism and a camera connected to the front end of the bracket for capturing images of the staple cartridge position and rotation. Specifically, the visual inspection mechanism also includes a light source located at the front end of the camera. After the fixing seat moves the stapler to the processing position, the camera captures images of the staple cartridge to check its position and whether the rotation angle is within acceptable limits, preventing stapler misalignment that could lead to stapler failure. Furthermore, capturing the stapler process allows for real-time adjustment of the stapler position, ensuring smooth stapler processing.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The high-speed stapler for medical staplers in this invention, through a first feeding section, a second feeding section, and corresponding first swing arm, first clamping section, second swing arm, and second clamping section, enables the stapler to simultaneously load staples on one side and unload staples on the other side. In conjunction with a rotating fixing seat, it achieves automatic and rapid staple loading, which not only avoids the problems of low efficiency, easy contamination, and easy error caused by manual staple loading, but also greatly reduces the time occupied by processing gaps, thus greatly improving the staple loading rate and significantly increasing processing efficiency.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be noted that the directional terms "front," "back," "left," and "right" are defined according to the feeding direction of the stapler. Specifically, when the person places the stapler on the fixing seat, the direction the person is facing is "front," and vice versa. When the person is facing forward, the person's left side is "left," and vice versa. The terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Reference Appendix Figure 1-6 The high-speed stapler device for medical staplers in this embodiment includes: The feeding mechanism 1 is used to convey titanium nails. The feeding mechanism 1 includes a first feeding part 11 and a second feeding part 12.

[0021] Positioning mechanism 2, used to fix the stapler and transfer it to the processing position, includes a tool for positioning the stapler in a staple cartridge (as shown in the attached document). Figure 2, Figure 5 (As shown in the middle label a) The fixed seat 21 is fixed in an upward orientation, the first drive unit 22 is connected below the fixed seat 21 and is used to drive the fixed seat 21 to rotate around the axis of the staple cartridge, and the second drive unit 23 is used to drive the fixed seat 21 to move in the front-back direction and in the left-right direction.

[0022] The nailing mechanism 3 is used to load titanium nails conveyed by the feeding mechanism 1 into the nail magazine. The nailing mechanism 3 includes a rotary joint 31 that is rotatably disposed between the first feeding section 11 and the second feeding section 12 about a vertically arranged first rotating shaft 311; a third driving section 32 for driving the rotary joint 31 to rotate; a first swing arm 33 and a second swing arm 34, one end of which is fixedly connected to the rotary joint 31; and a first clamping section 35 and a second clamping section 36 disposed at the other end of the first swing arm 33 and the second swing arm 34 for clamping and installing titanium nails. The nailing mechanism 3 has The device has at least two operating states. In the first operating state, the first swing arm 33 rotates to the discharge position of the first feeding section 11, and the first clamping part 35 clamps the titanium nail located at the discharge position. The second swing arm 34 rotates to the processing position, and the second clamping part 36 loads the clamped titanium nail into the nail magazine. In the second operating state, the first swing arm 33 rotates to the processing position, and the first clamping part 35 loads the clamped titanium nail into the nail magazine. The second swing arm 34 rotates to the discharge position of the second feeding section 12, and the second clamping part 36 clamps the titanium nail located at the discharge position. During production, the operator first fixes the stapler to be installed into the mounting base 21. Then, the second drive unit 23 moves the stapler to the processing position. Subsequently, the titanium staples are simultaneously fed by the first feeding unit 11 and the second feeding unit 12. When the titanium staples are fed to the discharge point, the third drive unit 32 drives the rotary joint to rotate, causing the first swing arm 33 and the second swing arm 34 to swing back and forth. First, the stapler mechanism enters the first working state. In this state, the first swing arm 33 performs a clamping action to facilitate material removal, while the second swing arm 34 performs an installation action to install the titanium staples. Then, the stapler mechanism enters the second working state. In this state, the first swing arm 33 performs the installation action, while the second swing arm 34 simultaneously performs the clamping action. During the switching of the working states of the stapler mechanism 3, the first drive unit 22 synchronously drives the mounting base 21 to rotate. Specifically... Each time the stapler mechanism 3 switches its working state, the first drive unit 22 drives the fixed base 21 to rotate one notch around the staple cartridge axis. The rotation angle of this one notch corresponds to the angle between the two adjacent staple slots at the front end of the staple cartridge and the staple cartridge axis. This ensures that after any staple slot is installed, the adjacent empty staple slot is aligned with the first clamping part 35 or the second clamping part 36, facilitating the continued installation of titanium staples. By repeatedly switching between the first and second working states, and cooperating with the first drive unit 22 to rotate the fixed base 21, the stapler can be automatically stapled. This avoids the problems of low efficiency, easy contamination, and easy errors caused by manual stapler. Furthermore, the two feeding parts and the corresponding two swing arms and clamping parts greatly reduce the time occupied by the processing gap, thus greatly improving the stapler processing speed and significantly increasing the processing efficiency.

[0023] In a more preferred embodiment, the fixing seat 21 is cylindrical and has a fixing groove 211 at the top for the staple cartridge of the stapler to be engaged therein. The positioning mechanism 2 also includes at least one limiting member 24 for limiting the position of the stapler when it is engaged in the fixing groove 211. By engaging the stapler in the fixing groove 211 and limiting and fixing its position by the limiting member 24, the fixing seat 21 can move the stapler to the processing position and control its rotation to facilitate staple loading.

[0024] In a more preferred embodiment, the first drive unit 22 includes a turntable 221 fixedly connected to the bottom of the fixed base 21, and a first driver 222 connected below the turntable 221 for driving the turntable 221 to rotate. The second drive unit 23 includes a first slide rail 231 arranged in the front-back direction, a first slide block 232 slidably connected to the first slide rail 231, a second driver 233 for driving the first slide block 232 to slide, a second slide rail 234 arranged in the left-right direction on the first slide block 232, a second slide block 235 slidably connected to the second slide rail 234, and a third driver 236 for driving the second slide block 235 to slide. The first driver 222 is fixedly connected to the second slide block 235. The first slide block 232 and the second slide block 235 are driven by the second driver 233 and the third driver 236 respectively, realizing the movement of the fixed base in the front-back direction and the left-right direction. The turntable is driven by the first driver, realizing the rotation of the fixed base.

[0025] In a more preferred embodiment, the first clamping part 35 includes a third slide rail 351 vertically disposed at the end of the first swing arm 33, a third slide block 352 slidably connected to the third slide rail 351, and a pair of first grippers 353 disposed at the lower end of the third slide block 352 and capable of opening or clamping relative to each other. The second clamping part 36 includes a fourth slide rail 361 vertically disposed at the end of the second swing arm 34, a fourth slide block 362 slidably connected to the fourth slide rail 361, and a pair of second grippers 363 disposed at the lower end of the fourth slide block 362 and capable of opening or clamping relative to each other. When the first swing arm 33 and the second swing arm 34 swing to the discharge point or processing position of the loading part, the first grippers 353 and the second grippers 363 move down synchronously along the third slide rail 351 and the fourth slide rail 361, respectively, to facilitate the operation of clamping or installing titanium nails. After the operation is completed, the first grippers and the second grippers move up synchronously to switch working states.

[0026] In a more preferred embodiment, the first clamping part 35 further includes a first pressing member 354 fixedly disposed on the third slide 352 and used to press the titanium nail into the nail magazine, and the second clamping part 36 further includes a second pressing member 364 fixedly disposed on the fourth slide 362 and used to press the titanium nail into the nail magazine. When the nailing mechanism 3 is in the first working state, the position of the second gripper 363 corresponds to the first nail groove, and the position of the second pressing member 364 corresponds to the second nail groove located on one side of the first nail groove and adjacent to the first nail groove. When the nailing mechanism 3 is in the second working state, the position of the first gripper 353 corresponds to the third nail groove located on the other side of the first nail groove and adjacent to the first nail groove, and the position of the first pressing member 354 corresponds to the first nail groove. It should be noted that the terms "first nail slot," "second nail slot," and "third nail slot" are used for ease of description and do not refer to any specific nail slot. In actual processing, nail slots are usually evenly distributed around the axis of the nail magazine. By setting the relative positions of the first and second pressing components, when the first or second gripper corresponds to the position of a nail slot for nailing, the first or second pressing component corresponds to the position of the adjacent nail slot. Furthermore, the first and second pressing components are set to move up and down synchronously with the first and second grippers, thereby facilitating the pressing of the titanium nail after it has been installed by the grippers, ensuring that the titanium nail can be installed in place and improving the nailing effect.

[0027] In a more preferred embodiment, the first feeding section 11 includes a first vibrating disc 111, a first feeding trough 112 connected at one end to the first vibrating disc 111, and a first distributing disc 113 rotatably disposed at the other end of the first feeding trough 112 about a rotating shaft arranged along the traveling direction of the titanium nails in the first feeding trough 112. The side of the first distributing disc 113 is evenly provided with a plurality of first receiving grooves 114 for accommodating titanium nails along its circumference. Each first receiving groove 114 has a first position and a second position due to the rotation of the first distributing disc 113. When it is in the first position, the first receiving groove 114 is connected to the other end of the first feeding trough 112. When the first receiving groove 114 is in the second position, the first receiving groove 114 is located at the discharge point of the first feeding section 11. When one first receiving groove 114 is in the second position, the other first receiving groove 114 is in the first position. The scattered titanium nails are conveyed one by one into the first feeding trough in the same and specific posture by the first vibrating plate. Then, by rotating the first distributing plate, the first receiving grooves opened on it are connected to the other end of the first feeding trough in sequence, so that the titanium nails conveyed to the other end of the first feeding trough are respectively included into several first receiving grooves, thereby separating the titanium nails individually, so that the first gripper can pick up the titanium nails from the first receiving groove.

[0028] In a more preferred embodiment, the first feeding part 11 further includes a first pneumatic push rod 115 disposed on the side of the first feeding groove 112 and used to push the titanium nail into the first receiving groove 114. Each first receiving groove 114 also has a third position between the first position and the second position due to the rotation of the first distributing plate 113. When it is in the third position, the first receiving groove 114 corresponds to the output end of the first pneumatic push rod 115. When one first receiving groove 114 is in the second position, the other two first receiving grooves 114 are in the third position and the first position, respectively. Each first receiving slot will sequentially pass through a first position, a third position, and a second position as the first dispensing tray rotates. In the first position, the first receiving slot receives the titanium nails conveyed from the first feeding slot. Then it rotates to the third position so that the first pneumatic push rod can push the titanium nails to ensure that the titanium nails are completely in the first receiving slot. This avoids adverse effects on the gripping and installation of the first clamping jaws due to the positional deviation of the titanium nails, and ensures the stability of the nail loading process. After being pushed into place, the first receiving slot rotates to the second position so that the first clamping jaws can pick up the titanium nails from here, thereby realizing the feeding of titanium nails.

[0029] In a more preferred embodiment, the second feeding section 12 includes a second vibrating disc 121, a second feeding trough 122 connected at one end to the second vibrating disc 121, and a second distributing disc 123 rotatably disposed at the other end of the second feeding trough 122 about a rotating shaft arranged along the traveling direction of the titanium nails in the second feeding trough 122. The side of the second distributing disc 123 is evenly provided with a plurality of second receiving grooves 124 for accommodating titanium nails along its circumference. Each second receiving groove 124 has a first position and a second position due to the rotation of the second distributing disc 123. When it is in the first position, the second receiving groove 124 is in contact with the other end of the second feeding trough 122. When the second receiving groove 124 is in the second position, the second receiving groove 124 is located at the discharge point of the second feeding section 12. When one second receiving groove 124 is in the second position, the other second receiving groove 124 is in the first position. The scattered titanium nails are conveyed one by one into the second feeding trough in the same and specific posture by the second vibrating plate. Then, by rotating the second distributing plate, the second receiving slots opened on it are connected to the other end of the second feeding trough in sequence, so that the titanium nails conveyed to the other end of the second feeding trough are respectively included into several second receiving slots, thereby separating the titanium nails individually, so that the second gripper can pick up the titanium nails from the second receiving slots.

[0030] In a more preferred embodiment, the second feeding section 12 further includes a second pneumatic push rod 125 disposed on the side of the second feeding groove 122 and used to push the titanium nails into the second receiving groove 124. Each second receiving groove 124 also has a third position between the first position and the second position due to the rotation of the second distributing plate 123. When it is in the third position, the output end of the second receiving groove 124 and the second pneumatic push rod 125 correspond to the second receiving groove 124 being in the second position, while the other two second receiving grooves 124 are in the third position and the first position, respectively. Each second receiving slot passes through a first position, a third position, and a second position sequentially as the second dispensing disc rotates. In the first position, the second receiving slot receives the titanium nails conveyed from the second feeding slot. It then rotates to the third position so that the second pneumatic push rod can push the titanium nails, ensuring that the titanium nails are completely within the second receiving slot. This avoids adverse effects on the gripping and installation of the second clamping jaws due to titanium nail position deviation, ensuring the stability of the nail loading process. After being pushed into position, the second receiving slot rotates to the second position so that the second clamping jaws can pick up the titanium nails from this position, thereby realizing the feeding of titanium nails.

[0031] In a more preferred embodiment, the high-speed stapler also includes a visual inspection mechanism 4 for detecting the position of the fixing seat 21. The visual inspection mechanism 4 includes a bracket 41 fixedly mounted above the stapler mechanism 3 and a photographing device 42 connected to the front end of the bracket 41 for photographing the position and rotation of the staple cartridge of the stapler. Specifically, the visual inspection mechanism also includes a light source located at the front end of the photographing device. After the fixing seat moves the stapler to the processing position, the photographing device takes a picture of the staple cartridge to detect its position and whether the rotation angle is qualified, so as to avoid stapler failure due to stapler misalignment. Furthermore, by photographing the stapler process, the position of the stapler can be adjusted in real time to ensure the smooth progress of the stapler processing.

[0032] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The high-speed stapler for medical staplers in this invention, through a first feeding section, a second feeding section, and corresponding first swing arm, first clamping section, second swing arm, and second clamping section, enables the stapler to simultaneously load staples on one side and unload staples on the other side. In conjunction with a rotating fixing seat, it achieves automatic and rapid staple loading, which not only avoids the problems of low efficiency, easy contamination, and easy error caused by manual staple loading, but also greatly reduces the time occupied by processing gaps, thus greatly improving the staple loading rate and significantly increasing processing efficiency.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
