Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an eagle beak installer and the eagle beak assembly thereof. Background Technology

[0002] The beak-like component at the tip of the electric stapler protects tissue in the blind spot of the operation area. Inserting the beak component helps the instrument navigate narrow spaces more effectively, especially safely when entering the posterior part of a blood vessel. Furthermore, the beak component better secures vascular tissue within the jaws. Current electric staplers are available with and without beaks. Detachable beaks mostly use clips for connection, but these clips present difficulties in installation and removal.

[0003] Existing technology CN202321453562.2 discloses a pluggable hawk-beak staple cartridge assembly for an electric stapler, relating to the field of medical device technology. It includes: a staple seat support, a staple seat, a hawk beak, and a staple cartridge support. One end of the staple seat is hinged to the staple seat support, and the other end has a insertion hole extending along the length of the staple seat, with a groove on the side wall of the insertion hole. One end of the hawk beak has a mounting hole for the end of the staple seat away from the staple seat support to be inserted into. A mounting post is provided in the mounting hole that can be inserted into the insertion hole, and a buckle that can be inserted into the groove is connected to the mounting post. The staple cartridge support is fixedly connected to the staple seat support, and a staple cartridge is installed on the staple cartridge support. Although this solution allows for quick assembly and disassembly of the hawk beak, the following problems still exist: 1. This solution improves the hook and loop mechanism to facilitate disassembly and assembly. However, the hook and loop still require medical staff to operate the clips manually. They need to accurately align the clips with the stapler and press to operate. Medical staff need to wear latex gloves to operate, which makes it difficult to apply force and requires repeated adjustments to the grip to complete the installation of the hook and loop. Furthermore, during surgery, due to the moist environment of blood and other substances, and the need to apply vertical pressure to unlock the clips, the small size of the hook and loop makes it easy for the surgeon's fingers to slip. Medical staff need to repeatedly adjust the grip to press the clips, which affects the progress of the surgery.

[0004] 2. Existing technologies improve the ease of assembly and disassembly by modifying the structure of the eagle beak body, but they do not solve the problem of relying on manual operation. Manual operation cannot meet the requirements of precision, safety and ergonomics of medical devices. In addition, manual operation lacks the necessary mechanical amplification or guiding structure and relies entirely on the operator's own strength control. It cannot adapt to the different operating habits and strength differences of different medical staff, and has obvious human-computer interaction design defects, making it difficult to meet the development needs of modern medical devices for precise and intelligent operation. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an eagle beak installer and the eagle beak assembly thereof. By using the eagle beak installer to assist medical staff in quickly installing the eagle beak, the problem of difficulty in applying force and slippery fingers when medical staff are wearing latex gloves is effectively solved, and the convenience and efficiency of eagle beak installation and removal are significantly improved.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A beak installer and a beak assembly thereof are provided, comprising: a housing and a limiting cavity for receiving the beak; The front end of the limiting cavity is symmetrically provided with guide limiting blocks on both inner walls. The guide limiting blocks can guide the beak into the limiting cavity and limit the upper surface of the beak connection. The rear end of the limiting cavity is provided with a limiting member, which can limit the distance of the beak into the limiting cavity. The shell is wrapped around the outside of the limiting cavity, and one end face of the shell is flush with the front end face of the limiting cavity.

[0007] It should be noted that the limiting cavity is formed by a bottom plate whose bottom shape corresponds to the bottom of the beak connector and side plates on both sides, allowing the beak to be placed inside the limiting cavity. Guide limiting blocks are symmetrically arranged on the inner walls of the front two sides of the limiting cavity, and their shape matches the contour of the beak connector. When the beak is inserted into the limiting cavity, the guide limiting blocks and the bottom of the limiting cavity cooperate to constrain the upper and lower surfaces of the beak connector, while the inner walls on both sides of the limiting cavity constrain the sides of the connector. This geometric constraint reduces the offset of the beak during insertion, allowing it to quickly align with the center of the limiting cavity along a preset path. The limiting components (such as arc-shaped limiting plates, protruding structures, etc.) are located at the rear end of the limiting cavity. When the nozzle is inserted to the preset position, the limiting components contact the tip or connecting part of the nozzle, and prevent the nozzle from going further in through mechanical stops, thereby precisely controlling the longitudinal position of the nozzle in the limiting cavity. The housing, as an external support structure, forms a rigid whole by wrapping the limiting cavity, ensuring that the positions of the guide limiting block and the limiting components remain fixed. Moreover, one end of the housing is flush with the front end face of the limiting cavity, so that the front end of the nozzle can be directly aligned with the stapler interface during installation, which facilitates the precise alignment and quick installation of the nozzle.

[0008] Preferably, the limiting member is an arc-shaped limiting plate corresponding to the tip of the eagle's beak, which can support and limit the tip of the eagle's beak; and the two ends of the arc-shaped limiting plate are respectively connected to the rear end of the limiting cavity and the inner wall of the shell.

[0009] It should be noted that the curved contour of the arc-shaped limiting plate precisely matches the outer contour of the tip of the eagle beak (such as an arc or a cone), forming a surface contact support. When the eagle beak is inserted into the limiting cavity, the tip gradually approaches the arc-shaped limiting plate until the two are completely in contact. This physical contact restricts the longitudinal movement (insertion depth) of the eagle beak, eliminating the need for medical personnel to manually adjust its position. They only need to insert it until it contacts the arc-shaped limiting plate to complete the positioning, simplifying the operation process. Furthermore, one end of the arc-shaped limiting plate is fixed to the rear end of the limiting cavity (such as by welding or snap-fit ​​connection), while the other end is connected to the inner wall of the shell, forming a cantilever support structure. This design allows the limiting plate to withstand the pressure of the eagle beak tip, with the rigid support of the shell offsetting the reaction force, preventing the limiting plate itself from shifting or deforming, and ensuring the limiting accuracy.

[0010] Preferably, the housing has at least one pressing part corresponding to the buckle position of the eagle beak, and the pressing part can apply pressure to the buckle of the eagle beak to realize the assembly and disassembly of the eagle beak.

[0011] It should be noted that the pressing part is set at the corresponding buckle position. However, the buckle position and number of existing staplers vary (e.g., buckles are located on both sides of the stapler). Therefore, the number of pressing parts must be at least consistent with the number of buckles. The pressing part is located on the surface of the housing and aligned with the buckle position of the stapler. When the operator presses this part, the applied force is transmitted to the buckle through the mechanical structure. The buckle is usually an elastic locking structure (such as a spring plate or plastic latch). The vertical pressure applied by the pressing part forces the buckle to deform or displace, releasing its locked state with the stapler, thereby realizing the disassembly or installation of the stapler. At the same time, by amplifying or concentrating the operating force through the pressing part, the buckle can still be effectively triggered even when wearing latex gloves or with wet hands, solving the problem of difficulty in applying force in traditional manual operation.

[0012] Preferably, the pressing part includes a pressing plate and a pin. The pressing plate is disposed on the housing corresponding to the buckle of the eagle's beak. The pin is fixedly disposed on the pressing plate and located between the buckle and the pressing plate. The pin can move axially and transmit pressure to the buckle when the pressing plate is subjected to force.

[0013] It should be noted that the pressure plate, as the operator's direct point of force, is displaced by external pressure (such as finger pressure), and its surface area is larger than that of the force-bearing end of the ejector pin. By increasing the contact area with the fingers, the operating pressure is reduced, allowing medical staff to unlock the buckle with less force. The ejector pin is rigidly connected to the pressure plate and moves synchronously with the pressure plate, accurately transmitting the applied force axially to the buckle, so that the end of the ejector pin contacts the buckle (such as an elastic latch or spring plate). The vertical pressure forces the buckle to deform or displace, releasing its locked state with the stapler and completing the disassembly or installation of the eagle beak.

[0014] Preferably, pressing parts are provided on both the upper and lower sides of the housing, and a through hole is provided at the bottom of the limiting cavity corresponding to the lower ejector pin for it to pass through, so that the ejector pin can pass through the through hole to apply pressure to the buckle of the eagle beak after being pressed by the pressing part.

[0015] It should be noted that the pressing parts on the upper and lower sides of the housing correspond to the upper and lower positions of the eagle beak buckle, respectively. The operator can press both sides simultaneously or apply force to one side to apply pressure to the corresponding buckle position, so that the installer can be used for the disassembly and assembly of two types of eagle beaks with buckle positions at the upper and lower ends of the eagle beak connection. The diameter of the through hole at the bottom of the limiting cavity is slightly larger than the outer diameter of the ejector pin, ensuring that the lower ejector pin is not blocked by the limiting cavity when moving. At the same time, the guiding effect of the through hole edge maintains the verticality of the ejector pin's movement trajectory, avoiding deformation of the ejector pin due to tilting force, and ensuring that the pressure is accurately transmitted to the buckle.

[0016] Preferably, the guide limiting block includes a guide part and a limiting part, the guide part and the limiting part are integrally formed, the guide part is located at the front end of the limiting part and is arc-shaped as a whole, and the arc surface of the guide part matches the sliding path of the beak connecting part.

[0017] It should be noted that the curved surface of the guide part is highly matched with the sliding trajectory of the beak connecting part. Through geometric fit, the beak is guided to slide into the limiting cavity along the preset path. The curved design reduces the frictional resistance during the sliding process, allowing the beak to enter smoothly and avoiding jamming or misalignment caused by path deviation. The limiting part is located at the rear end of the guide part. When the beak slides to the limiting part, the lower surface of the limiting part abuts tightly with the upper surface of the beak connecting part. By cooperating with the bottom of the limiting cavity, the upper and lower surfaces of the beak connecting part are limited. The one-piece molding structure makes the guide part and the limiting part seamlessly connected, eliminating the assembly gap in the traditional split design and improving positioning accuracy.

[0018] Preferably, the surface of the housing is provided with an anti-slip portion, which is arranged along the axial direction of the housing on the outer surface of the housing and extends to the outer surface of the pressing portion.

[0019] It should be noted that the anti-slip part breaks the continuity of the smooth surface by increasing the roughness of the shell surface or physical protrusions (such as strip-shaped or granular structures), thereby increasing the static friction coefficient between the hand and the shell during operation. In addition, the anti-slip part extends along the long axis of the shell, which is consistent with the natural grip direction of the fingers, ensuring that the hand can effectively grip at different grip angles and avoid slipping. The anti-slip part covers the outer surface of the pressing part, so that the operator can still maintain stable force when pressing, preventing pressing deviation or accidental touch due to finger slippage.

[0020] Preferably, the anti-slip part is a strip-shaped protrusion arranged in an array along the axial direction of the housing. The strip-shaped protrusion is arranged laterally on the upper and lower surfaces of the housing and arrayed on the outer surface of the pressing part.

[0021] It should be noted that the horizontally arranged strip-shaped protrusions increase the contact area and roughness between the hand and the shell surface, forming a micro-uneven structure that significantly improves the static friction coefficient. The direction of the strip-shaped protrusions is perpendicular to the shell axis and consistent with the direction of lateral force applied when the fingers are naturally gripping, providing stronger anti-slip capability during push-pull or rotation operations. The protrusions extend to the outer surface of the pressing part. When the fingers press the pressing plate, the fingertips contact the horizontal ridges of the protrusions, and the vertical force of the pressing action is converted into compressive stress on the protrusions, further enhancing the friction and preventing the fingers from slipping off the surface of the pressing plate during pressing.

[0022] Preferably, the side of the housing is provided with an arc-shaped groove, the curvature of which matches the grip curve of human fingers.

[0023] It should be noted that the curvature of the arc-shaped groove is designed based on the natural physiological curve of the human finger, allowing the operator's main gripping fingers, such as the index and middle fingers, to naturally fit into the groove, reducing muscle tension and fatigue during gripping. When wet or wearing gloves, the curvature of the groove fits the fingers even more closely, reducing instrument displacement caused by hand slippage. The stable grip reduces hand tremors, ensuring precise docking of the eagle beak installer and the stapler, and reducing surgical risks caused by misoperation.

[0024] An eagle beak assembly includes an eagle beak installer and an eagle beak as described in any one of the above claims. The eagle beak includes a connecting portion, a tip portion, and a snap fastener. The eagle beak is placed in the limiting cavity of the installer. The lower surface of the guide limiting block abuts against the upper surface of the eagle beak connecting portion. The arc-shaped limiting plate abuts against the tip portion of the eagle beak. The snap fastener position of the eagle beak corresponds to the position of the ejector pin, and the ejector pin can be moved toward the snap fastener by a pressing portion.

[0025] It should be noted that the eagle beak structure is relatively small, and its installation relies on manual alignment by medical staff, which is easily affected by hand tremors or obstructed vision. This solution transforms the traditionally separate instrument components into a cohesive whole by placing the eagle beak inside the installer in advance. Medical staff no longer need to manually grasp the eagle beak during surgery; they can directly hold the installer as a whole for docking operations, thus solving the problems of low efficiency, poor precision, and easy contamination associated with traditional manual operation.

[0026] The beneficial effects of this utility model are: This utility model provides an eagle beak installer and its constituent eagle beak assembly. Through symmetrically arranged guide blocks at the front end of the limiting cavity, the eagle beak can be precisely guided into the limiting cavity quickly and accurately, limiting the upper surface of the eagle beak connection. Combined with the rear arc-shaped limiting plate, which supports and limits the tip of the eagle beak and restricts the insertion depth, stable positioning of the eagle beak is achieved within the installer, solving the problem of repeated adjustments required for manual installation in existing technologies. The pressing plate and ejector pin structure of the pressing part can transmit pressure to the eagle beak latch through axial movement of the ejector pin, avoiding direct manual operation of the tiny latches by medical personnel. This effectively solves the problems of difficulty in applying force and slippage when operating with latex gloves, significantly improving the convenience and efficiency of eagle beak assembly and disassembly. The arc-shaped outer side of the shell... The groove is designed to match the curve of the human finger grip, and the anti-slip surface (such as strip-shaped protrusions) extends to the outer surface of the pressing part, optimizing the human-computer interaction experience. It provides a stable grip even in the moist surgical environment, meeting the ergonomic requirements of medical devices. In addition, the combination structure of the installer and the eagle beak forms a standardized mechanical fit through the abutment of the guide limit block and the eagle beak connection part, and the precise correspondence between the ejector pin and the buckle position. This not only reduces operational errors but also adapts to the differences in strength among different medical personnel, avoiding the mechanical control defects of manual operation, improving the accuracy and safety of medical device operation, effectively making up for the human-computer interaction gap in existing technologies that rely on manual operation, and meeting the development needs of modern medical devices for intelligent and precise operation.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1 like Figure 1 and Figure 2 As shown, an eagle beak installer includes: a housing 1 and a limiting cavity 2 for accommodating an eagle beak 7; The front end of the limiting cavity 2 is provided with symmetrical guide limiting blocks 3 on both inner walls. The guide limiting blocks 3 can guide the beak 7 into the limiting cavity 2 and limit the upper surface of the connecting part 71 of the beak 7. The rear end of the limiting cavity 2 is provided with a limiting member 4. The limiting member 4 can limit the distance of the beak 7 into the limiting cavity 2. The shell 1 is wrapped around the outside of the limiting cavity 2, and one end face of the shell 1 is flush with the front end face of the limiting cavity 2.

[0040] The limiting member 4 is an arc-shaped limiting plate 41 corresponding to the tip 72 of the beak 7. The arc-shaped limiting plate 41 can support and limit the tip 72 of the beak 7. The two ends of the arc-shaped limiting plate 41 are respectively connected to the rear end of the limiting cavity 2 and the inner wall of the shell 1.

[0041] The guide limiting block 3 includes a guide part 31 and a limiting part 32. The guide part 31 and the limiting part 32 are integrally formed. The guide part 31 is located at the front end of the limiting part 32 and is arc-shaped as a whole. The arc surface of the guide part 31 matches the sliding path of the eagle beak 7 connecting part 71.

[0042] The side of the housing 1 is provided with an arc-shaped groove 11, the curvature of which matches the grip curve of human fingers.

[0043] The working principle and usage method of an eagle beak installer in this embodiment are as follows: This embodiment provides an eagle beak installer. The positioning space for the eagle beak 7 is constructed by the limiting cavity 2 enclosed by the housing 1. The guide limiting blocks 3 on both sides of the front end of the limiting cavity 2 use an integrally formed arc-shaped guide part 31 and a rear limiting part 32 to guide the eagle beak 7 to slide in along a preset path when it is inserted. After it is in place, the limiting part 32 and the bottom of the limiting cavity 2 cooperate to constrain the upper and lower surfaces of the connecting part 71 of the eagle beak 7, thereby achieving lateral positioning. The arc-shaped limiting plate 41 at the rear end of the limiting cavity 2 fits with the tip 72 of the eagle beak 7 through its curved surface to form a longitudinal stop, limiting the insertion depth and ensuring that the eagle beak 7 buckle 73 is accurately aligned with the external operating structure. The arc-shaped groove 11 on the side of the housing 1 fits the finger grip curve and provides stable grip support, allowing medical staff to easily align the front end of the eagle beak 7 with the stapler interface by holding the housing 1, thereby completing the rapid installation of the eagle beak 7.

[0044] In use, first align the eagle beak 7 with the front end of the limiting cavity 2, and gently push it in along the arc-shaped guide part 31 of the guide limiting block 3. Use the curved surface of the guide part 31 to guide the eagle beak 7 to slide into the limiting cavity 2 until the tip 72 of the eagle beak 7 abuts against the arc-shaped limiting plate 41 at the rear end, completing the lateral and longitudinal positioning. Then, hold the arc-shaped groove 11 on the side of the housing 1, and use the groove that fits the curve of your fingers to hold it stably. Align the front end of the installer with the interface of the stapler, and then push the housing 1 towards the stapler so that the eagle beak 7 buckle 73 is aligned with the stapler slot and gently pressed into place to complete the installation of the eagle beak 7.

[0045] Example 2 like Figure 3 and Figure 4 As shown, an eagle beak installer of this embodiment includes: a housing 1 and a limiting cavity 2 for accommodating an eagle beak 7; The front end of the limiting cavity 2 is provided with symmetrical guide limiting blocks 3 on both inner walls. The guide limiting blocks 3 can guide the beak 7 into the limiting cavity 2 and limit the upper surface of the connecting part 71 of the beak 7. The rear end of the limiting cavity 2 is provided with a limiting member 4. The limiting member 4 can limit the distance of the beak 7 into the limiting cavity 2. The shell 1 is wrapped around the outside of the limiting cavity 2, and one end face of the shell 1 is flush with the front end face of the limiting cavity 2.

[0046] The limiting member 4 is an arc-shaped limiting plate 41 corresponding to the tip 72 of the beak 7. The arc-shaped limiting plate 41 can support and limit the tip 72 of the beak 7. The two ends of the arc-shaped limiting plate 41 are respectively connected to the rear end of the limiting cavity 2 and the inner wall of the shell 1.

[0047] The housing 1 is provided with a pressing part 5 at the position of the buckle 73 corresponding to the beak 7. The pressing part 5 can apply pressure to the buckle 73 of the beak 7 to realize the assembly and disassembly of the beak 7.

[0048] The pressing part 5 includes a pressing plate 51 and a pin 52. The pressing plate 51 is disposed on the housing 1 corresponding to the buckle 73 of the beak 7. The pin 52 is fixedly disposed on the pressing plate 51 and located between the buckle 73 and the pressing plate 51. The pin 52 can move axially and transmit pressure to the buckle 73 when the pressing plate 51 is subjected to force.

[0049] The guide limiting block 3 includes a guide part 31 and a limiting part 32. The guide part 31 and the limiting part 32 are integrally formed. The guide part 31 is located at the front end of the limiting part 32 and is arc-shaped as a whole. The arc surface of the guide part 31 matches the sliding path of the eagle beak 7 connecting part 71.

[0050] The surface of the housing 1 is provided with an anti-slip part 6, which is arranged along the axial direction of the housing 1 on the outer surface of the housing 1 and extends to the outer surface of the pressing part 5.

[0051] The anti-slip part 6 is a strip-shaped protrusion 61 arranged in an array along the axial direction of the housing 1. The strip-shaped protrusion 61 is arranged laterally on the upper and lower surfaces of the housing 1 and arrayed on the outer surface of the pressing part 5.

[0052] The side of the housing 1 is provided with an arc-shaped groove 11, the curvature of which matches the grip curve of human fingers.

[0053] The working principle and usage method of an eagle beak installer in this embodiment are as follows: This embodiment provides an eagle beak installer. The eagle beak 7 slides into the cavity through the arc-shaped guide limiting blocks 3 on both sides of the front end of the limiting cavity 2. The arc surface of the guide part 31 matches the sliding path of the connecting part 71 of the eagle beak 7, guiding it to enter accurately along a preset trajectory. When inserted to the rear end, the tip 72 of the eagle beak 7 fits against the arc-shaped limiting plate 41, and the insertion depth is limited by the physical stop to ensure consistent positioning. The single pressing part 5 on the housing 1 corresponds to the position of the eagle beak 7 buckle 73. When pressed, the pressing plate 51 drives the ejector pin 52 to move axially. The end of the ejector pin 52 accurately acts on the unlocking point of the buckle 73. By applying vertical pressure, the buckle 73 is elastically deformed, which can quickly release the locking state between the eagle beak 7 and the stapler. The transverse strip protrusion 61 of the anti-slip part 6 and the arc groove 11 on the side of the housing 1 provide a stable grip. Even with one-handed operation, the pressing direction can be ensured to be vertical, avoiding the ejector pin 52 from getting stuck or the buckle 73 from being damaged due to force deviation. The simplified operation of disassembly and assembly can be completed by a single point press.

[0054] When using, align the connecting part 71 of the eagle beak 7 with the front end of the limiting cavity 2, and slide it into the limiting cavity 2 along the arc surface of the guide limiting blocks 3 on both sides until the tip 72 of the eagle beak 7 is completely in contact with the arc limiting plate 41 at the rear end, thus completing the insertion depth positioning; when holding, place your fingers on the arc groove 11 on the side of the housing 1, and use the horizontal strip protrusion 61 of the anti-slip part 6 to grip it stably, align the front end of the installer with the anastomosis device interface, and gently push the installer to accurately insert and lock the eagle beak 7, thus completing the installation of the eagle beak 7; when disassembling, similarly, put the installer on the eagle beak 7, and then press the pressing part 5 on the housing 1, which drives the pin 52 to act vertically on the eagle beak 7 buckle 73 through the pressing plate 51, forcing the buckle 73 to elastically deform and unlock, and then gently pull in the opposite direction to remove the eagle beak 7.

[0055] Example 3 like Figure 5 and Figure 6 As shown, an eagle beak installer of this embodiment includes: a housing 1 and a limiting cavity 2 for accommodating an eagle beak 7; The front end of the limiting cavity 2 is provided with symmetrical guide limiting blocks 3 on both inner walls. The guide limiting blocks 3 can guide the beak 7 into the limiting cavity 2 and limit the upper surface of the connecting part 71 of the beak 7. The rear end of the limiting cavity 2 is provided with a limiting member 4. The limiting member 4 can limit the distance of the beak 7 into the limiting cavity 2. The shell 1 is wrapped around the outside of the limiting cavity 2, and one end face of the shell 1 is flush with the front end face of the limiting cavity 2.

[0056] The limiting member 4 is an arc-shaped limiting plate 41 corresponding to the tip 72 of the beak 7. The arc-shaped limiting plate 41 can support and limit the tip 72 of the beak 7. The two ends of the arc-shaped limiting plate 41 are respectively connected to the rear end of the limiting cavity 2 and the inner wall of the shell 1.

[0057] The upper and lower sides of the housing 1 are respectively provided with pressing parts 5, which can apply pressure to the buckle 73 of the beak 7 to realize the assembly and disassembly of the beak 7.

[0058] The pressing part 5 includes a pressing plate 51 and a pin 52. The pressing plate 51 is disposed on the housing 1 corresponding to the buckle 73 of the beak 7. The pin 52 is fixedly disposed on the pressing plate 51 and located between the buckle 73 and the pressing plate 51. The pin 52 can move axially and transmit pressure to the buckle 73 when the pressing plate 51 is subjected to force.

[0059] The bottom of the limiting cavity 2 has a through hole 21 for the lower ejector pin 52 to pass through, so that the ejector pin 52 can apply pressure to the buckle 73 of the beak 7 after the pressing part 5 is pressed through the through hole 21.

[0060] The guide limiting block 3 includes a guide part 31 and a limiting part 32. The guide part 31 and the limiting part 32 are integrally formed. The guide part 31 is located at the front end of the limiting part 32 and is arc-shaped as a whole. The arc surface of the guide part 31 matches the sliding path of the eagle beak 7 connecting part 71.

[0061] The surface of the housing 1 is provided with an anti-slip part 6, which is arranged along the axial direction of the housing 1 on the outer surface of the housing 1 and extends to the outer surface of the pressing part 5.

[0062] The anti-slip part 6 is a strip-shaped protrusion 61 arranged in an array along the axial direction of the housing 1. The strip-shaped protrusion 61 is arranged laterally on the upper and lower surfaces of the housing 1 and arrayed on the outer surface of the pressing part 5.

[0063] The side of the housing 1 is provided with an arc-shaped groove 11, the curvature of which matches the grip curve of human fingers.

[0064] Compared with Example 2: This embodiment provides an eagle beak installer with pressing parts 5 on both the upper and lower sides of the housing 1, and a through hole 21 corresponding to the lower ejector pin 52 at the bottom of the limiting cavity 2, which can apply pressure to the buckles 73 on both the upper and lower sides of the eagle beak 7. It can not only be used for the disassembly and assembly of eagle beak 7 with buckle 73 positions at the upper or lower end of the connecting part 71 of the eagle beak 7, but also for eagle beak 7 with double buckle 73 structure (i.e., the connecting part 71 of the eagle beak 7 has buckle 73 structure on both the upper and lower sides), which significantly improves the operating efficiency and expands the applicability of the installer.

[0065] It should be noted that the existing eagle beak 7 has a structure with buckles 73 set on both sides, so the pressing part 5 can be set on both sides of the housing 1. It is only necessary to open through holes 21 on the side walls of the limiting cavity 2 so that the ejector pin 52 can pass through.

[0066] Example 4 like Figures 7-9 As shown, an eagle beak assembly includes: the eagle beak 7 installer described in Embodiment 3 and the eagle beak 7, wherein the eagle beak 7 includes a connecting portion 71, a tip portion 72, and a snap fastener 73. The beak 7 is placed inside the limiting cavity 2 of the installer; the lower surface of the guide limiting block 3 abuts against the upper surface of the connecting part 71 of the beak 7, the arc-shaped limiting plate 41 abuts against the tip 72 of the beak 7, the position of the buckle 73 of the beak 7 corresponds to the position of the ejector pin 52, and the ejector pin 52 can be moved toward the buckle 73 by pressing part 5. The working principle and usage method of an eagle beak component in this embodiment are as follows: This embodiment provides a beak assembly. By pre-positioning the beak 7 within the beak 7 installer limiting cavity 2 of Embodiment 3, the beak 7 is positioned, reducing the difficulty for medical staff to manually grasp the beak 7 during surgery, avoiding alignment deviations caused by hand tremors, and reducing positioning errors caused by obstructed vision or narrow space in traditional manual operations. At the same time, the closed positioning of the beak 7 within the limiting cavity 2 prevents medical staff from directly contacting sterile areas (such as the tip 72), conforming to aseptic operation standards. The anti-slip part 6 and arc-shaped groove 11 design of the installer housing 1 allow the operator to directly push or press the installer with a stable grip to quickly connect the beak 7 to the stapler.

[0067] When using, first remove the pre-installed eagle beak 7 installer from the aseptic packaging, confirm that the required eagle beak 7 is pre-installed in the installer, then hold the arc-shaped groove 11 on the side of the housing 1, and use the anti-slip part 6 of the strip protrusion 61 to hold it firmly, align the front end of the installer with the interface of the stapler, so that the axis of the eagle beak 7 is consistent with the axis of the interface; then, depending on the type of buckle 73, press the pressing part 5 on the housing 1 to drive the ejector pin 52 to move axially, and act on the eagle beak 7 buckle 73 through the bottom through hole 21 until the locking (installation) or unlocking (disassembly) with the stapler is completed.

[0068] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is used only to illustrate the technical solution of this utility model, and is not intended to limit the protection scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the protection scope of this utility model.

[0069] In the description of this utility model, it should be understood that the terms "upper", "lower", "upper end", "lower end", "upper surface", "lower surface", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0070] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
