[0001] The present disclosure claims priority from Chinese patent application No. 202421299970.1, which was filed with the Chinese Patent Office on June 7, 2024 and is entitled “Stapler magazine assembly and stapling device”, and the entire contents of which are incorporated into the present disclosure by reference. Technical field

[0002] The present disclosure relates to the technical field of surgical instruments and in particular to a stapling magazine assembly and a stapling device. Background technology

[0003] A stapling device is a medical device commonly used for tissue anastomosis and suturing during surgical procedures. The stapling device comprises, among other things, a staple magazine holder, a staple magazine assembly, and a staple holder. The staple magazine assembly is typically detachably connected to the staple magazine holder, for example, by being inserted into a groove-shaped structure within the staple magazine holder. During the operation, a staple propulsion element is set in motion by a sliding structure, such as a cutting blade. The movement of the propulsion element fires the staple, which then comes into contact with a staple forming groove on the staple holder and deforms, for example, into a B-shape, thus completing the anastomosis.

[0004] It has proven that there is a risk that the staples in the staple magazine assembly will be fired and reloaded into the staple magazine holder, which at best can delay treatment and at worst can cause medical accidents. Contents of the Revelation

[0023] Optionally, the anvil is provided with a first forming groove, and the released clamps meet the first forming groove and deform.

[0024] In combination with the above-mentioned technical solutions, the embodiments of the present disclosure offer, for example, the following advantageous effects: In the stapler magazine assembly of the present disclosure, a mounting opening is provided on the stapler magazine, and an elastic limiting unit is mounted in the mounting opening to enable the mounting of the elastic limiting unit in the stapler magazine. The elastic limiting unit comprises an elastic force transmission structure, as well as a release section and a limiting section at both ends of the elastic force transmission structure, wherein the release section and the limiting section are arranged near the inner and outer ends of the mounting opening, respectively.When the staple magazine assembly is mounted in the staple magazine holder of the stapling device, the limiting section is positioned according to an adjustment area of ​​the staple magazine's outer surface. This adjustment area is a region of the staple magazine's outer surface opposite the staple magazine holder, for example, opposite the inner wall of the first groove-shaped structure of the staple magazine holder used to mount the staple magazine assembly. When the staple pusher moves in a staple-pushing direction, for example, from back to front, and comes into contact with the release section, at least some of the staples in the staple magazine are released.The release section is moved outwards relative to the staple magazine by interaction with the staple sliding element, and the elastic force transmission structure is driven by the release section to move the limiting section outwards relative to the staple magazine so that the limiting section rests against the inner wall of the first groove-shaped structure of the staple magazine holder. At this point, the potential energy of the elastic force transmission structure is relatively high. However, the normal use of the staple magazine assembly with the staple magazine holder is not affected, and the staple magazine assembly can be removed from the staple magazine holder normally.When the staple magazine assembly is removed from the staple magazine holder, the staple magazine holder no longer rests against the limiting section. Under the influence of the potential energy of the elastic force transmission structure, the limiting section moves towards the outside of the staple magazine. This results in the staple magazine assembly being relatively large at the limiting section, effectively forming a stop. Specifically, a blockage occurs when the staple magazine assembly is reinserted into the staple magazine holder in this state. This significantly increases the difficulty of inserting the staple magazine assembly with at least some staples already deployed, thus preventing, to a certain extent, incorrect assembly of the staple magazine assembly with at least some staples already deployed.

[0025] The stapling device of the present disclosure comprises the stapling magazine assembly described above and exhibits all the advantageous effects of the stapling magazine assembly. Figures

[0033] As in the Fig. Figures 1 to 6 show that the embodiments of the present disclosure provide a staple magazine assembly 1 comprising a staple magazine 11 and an elastic limiting unit 12, wherein the staple magazine 11 is provided with a mounting opening 111, on the mounting opening 111 the elastic limiting unit 12 is mounted.The elastic limiting unit 12 comprises an elastic force transmission structure 123, as well as a release section 121 and a limiting section 122, which are located at both ends of the elastic force transmission structure 123, wherein the release section 121 is located near the inner end of the mounting opening 111 and the limiting section 122 is located near the outer end of the mounting opening 111, wherein the release section 121 is arranged on the path of movement of a staple pushing element 13 moving in a staple pushing direction, and the limiting section 122 is arranged in an adjustment area 114, wherein the adjustment area 114 is an area of ​​the staple magazine 11 which is spaced apart from the staple magazine holder 2 and is located on the outside of the staple magazine 11.

[0034] In the present disclosure, the staple magazine assembly 1 is usable in a stapling device, wherein the stapling device has a staple magazine holder 2 at the front and an anvil 3. The anvil 3 and the staple magazine holder 2 are movable relative to each other, thereby enabling opening and closing.

[0035] The staple magazine assembly 1 can be mounted in the staple magazine holder 2. For example, the staple magazine holder 2 has a first groove-shaped structure 21. The staple magazine assembly 1 is mounted in the first groove-shaped structure 21, with at least the upper part of the staple magazine assembly 1 protruding from the first groove-shaped structure 21, so that the staples can subsequently be pushed out from the top of the staple magazine assembly 1 to come into contact with the anvil 3.

[0036] The staple pushing element 13 advances the staple from back to front. In practical use, when the stapling tool reaches into a predetermined insertion point, the anvil 3 and the staple magazine holder 2 close and press down on the fabric to be sewn. The staple pushing element 13 moves from back to front, for example, under the action of a cutting blade, and the staples are released sequentially from back to front, for example, upwards. The released staples encounter a first forming groove on the anvil 3 (not shown) and deform to sew the fabric. For example, the staples can deform into the shape of the letter "B".

[0037] It should be noted that the original maximum end position of the staple sliding element 13 is located at the rear end of the staple magazine 11. The staple sliding element 13 is spaced away from the release section 121, the limiting section 122 remains in its original state and does not move out of the staple magazine 11, thus the limiting section 122 is spaced away from the staple magazine holder 2. The staple magazine assembly 1 can therefore be easily inserted into the first groove-shaped structure 21 of the staple magazine holder 2.

[0038] In the present disclosure, the mounting opening 111 can be arranged on the first side wall 112 of the staple magazine 11, and the mounting opening 111 can also be arranged on the base plate of the staple magazine 11. There is no restriction in this regard.

[0039] The release section 121 of the elastic limiting unit 12 is located near the inner end of the mounting opening 111. For example, the release section 121 lies within the mounting opening 111 and away from the outer end of the mounting opening 111. The release section 121 is located on the clamp-sliding movement path of the clamp sliding element 13. The limiting section 122 of the elastic limiting unit 12 is located near the outer end of the mounting opening 111. For example, the limiting section 122 is arranged in the adjustment area 114.

[0040] The specific structure of the elastic limiting unit 12 is not restricted as long as it has an elastic force transmission structure 123, a release section 121, and a limiting section 122 at both ends of the elastic force transmission structure 123. The elastic force transmission structure 123 connects the release section 121 to the limiting section 122 and is designed to transmit the acting force between the release section 121 and the limiting section 122.For example, if the limiting section 122 is not blocked in the left and right directions and the triggering section 121 is pushed in the left and right directions, the elastic force transmission structure 123 is able to transmit the pressure to the limiting section 122 and move the limiting section 122; or if the limiting section 122 is blocked in the left and right directions and the triggering section 121 is pushed in the left and right directions, the elastic force transmission structure 123 deforms to accumulate energy as potential energy, and the distance between the limiting section 122 and the triggering section 121 in the left and right directions decreases.

[0041] When the staple sliding element 13 is pushed and moves along the staple-pushing path, for example from back to front, to come into contact with the release section 121, at least part of the staple in the staple magazine 11 is released, and the release section 121 moves outward relative to the staple magazine 11 under the sliding action of the staple sliding element 13. The elastic force transmission structure 123 drives the limiting section 122 to move outward relative to the staple magazine 11, and the limiting section 122 rests against the inner wall of the first groove structure 21. At this point, the staple magazine assembly 1 can be properly disassembled from the staple magazine holder 2.

[0042] When the staple magazine assembly 1 is removed from the staple magazine holder 2, the staple magazine holder 2 no longer blocks the limiting section 122. Under the potential energy of the elastic force transmission structure 123, the limiting section 122 moves outwards relative to the staple magazine 11, thereby enlarging the staple magazine assembly 1 and creating a stop state. In particular, the staple magazine assembly 1 cannot be reinserted into the staple magazine holder 2 in the stop state, thus preventing incorrect assembly of the staple magazine assembly 1.

[0043] Optionally, a release section 121 is provided at the end limit position of the clamp sliding element 13, which moves along its clamp sliding direction.

[0044] The clamp magazine assembly 1 of the present embodiment comprises only one elastic limiting unit 12, wherein the elastic limiting unit 12 comprises only one release section 121 and one limiting section 122 and the position of the mounting opening 111 corresponds to the end limit position of the clamp sliding element 13.

[0045] It is understood, however, that a plurality of mounting openings 111 can be provided, and accordingly, a plurality of elastic limiting units 12 can also be provided. Alternatively, the elastic limiting unit 12 can comprise several release sections 121, several elastic force transmission structures 123, and several limiting sections 122. The clamp sliding element 13 releases a varying number of clamps, and the clamps are located at different positions. The release sections 121 at the corresponding positions can each be triggered to move the corresponding limiting sections 122 and thus prevent incorrect assembly of the disassembled clamp magazine assembly 1.

[0046] It is understood that the end-limit position of the staple sliding element 13 is the position at which the staple sliding element 13 is located at the leading end of the staple magazine 11. When the staple sliding element 13 is in the end-limit position, all staples in the staple magazine 11 are released, i.e., the staple magazine 11 is empty.

[0047] After the staple magazine assembly 1 has been removed from the staple magazine holder 2, the limiting section 122 of the elastic limiting unit 12 protrudes from the mounting opening 111 to prevent incorrect assembly of the empty staple magazine assembly 1 and to avoid assembly of the empty staple magazine assembly 1 into the staple magazine holder 2, which would have adverse effects.

[0048] Optionally, the staple magazine assembly 1 further comprises a staple magazine housing 14, wherein the staple magazine housing 14 is detachably connected to the staple magazine 11 and the staple magazine housing 14 is connected to the staple magazine holder 2. A through-opening 141 is provided in the staple magazine housing 14, wherein the through-opening 141 is connected to the mounting opening 111 and the limiting section 122 can pass through the through-opening 141.

[0049] The releasable connection between the stapler housing 14 and the stapler magazine 11 can be designed as a snap-fit ​​connection, and the stapler magazine assembly 1 is connected via the stapler housing 14 to the first groove-shaped structure 21 of the stapler magazine holder 2, for example by a snap-fit ​​connection. The connection method of the two can use related technologies, such as those of the applicant of the present disclosure prior to the filing date, which are not further explained here.

[0050] The staple magazine housing 14 protects the base of the staple magazine 11 and the limiting section 122 can easily move outwards relative to the staple magazine 11, for example to the left or right, and rest against the inner wall of the first groove-shaped structure 21 of the staple magazine holder 2.

[0051] Optionally, the elastic limiting unit 12 is designed as a spring-sheet structure, wherein the mounting end of the elastic limiting unit is attached to the mounting opening 111 and the spring-sheet structure further comprises the limiting section 122, the elastic force transmission structure 123 and the release section 121, which are connected sequentially, with the limiting section 122 being arranged in the mounting opening 111. The elastic limiting unit 12 has a simple design and high reliability.

[0052] The spring sheet structure can consist of either a single spring sheet or several interconnected spring sheets, which is not a limitation as long as the application requirements can be met.

[0053] As in Fig. As shown in Figure 2, the spring sheet structure is optionally bent and forms a first section 12a, a second section 12b and a third section 12c, which are connected one after the other, wherein the first section 12a is fixedly connected to the clamp magazine 11 at the circumferential side of the mounting opening 111 to form a fastening end of the spring sheet structure, the second section 12b and the third section 12c are each arranged obliquely to the first section 12a and at an angle, and the angle formed by the second section 12b and the third section 12c is open towards the mounting opening 111, wherein the third section 12c forms the elastic force transmission structure 123.

[0054] As in Fig. As shown in Figure 2, the spring-sheet structure optionally rests against the clamp magazine 11 at the first section 12a, so that the mounting end of the spring-sheet structure is attached to the clamp magazine 11. The limiting section 122 is arranged at one end of the third section 12c near the outside of the mounting opening 111, the release section 121 is arranged at one end of the third section 12c near the inside relative to the mounting opening 111, and the second section 12b is arranged at an angle to the first section 12a.

[0055] The elastic limiting unit 12 can be manufactured by bending a single spring sheet, eliminating the need for multiple components. The elastic limiting unit has a simple design, allowing the third section 12c to move as a whole relative to the first section 12a, and enabling the position of the third section 12c to be reset via the second section 12b. For example, the end of the third section 12c near the second section 12b can be moved relative to the first section 12a in the depth direction of the mounting opening 111, i.e., to the left or right, to reset its position.The third section 12c is arranged at an angle relative to the first section 12a, so that the trigger section 121 and the limiting section 122 of the third section 12c can move relative to each other and, through the deformation of the third section 12c, can accumulate potential energy, whereby the relative positions of the trigger section 121 and the limiting section 122 can be reset by the deformation of the third section 12c itself, which demonstrates a simple design and strong practicality.

[0056] Optionally, the first section 12a is connected to the plug-in section 12d and a plug-in slot 113 is arranged on the clamp magazine 11, wherein the plug-in section 12d is inserted into the plug-in slot 113.

[0057] Optionally, the first section 12a is bent at an end furthest from the second section 12b to form the plug-in section, and the depth direction of the plug slot 113 can coincide with the depth direction of the mounting opening 111. As shown in the Fig. 1, Fig. 2 and Fig. As shown in Figure 5, the first section 12a lies against the outside of the mounting opening 111 and against the clamp magazine 11. The end of the first section 12a furthest from the second section 12b is bent inwards into the clamp magazine 11 to form the plug-in section.

[0058] The plug connection between the plug section 12d and the plug slot 113 improves the reliability of the connection between the fastening end of the spring sheet structure and the clamp magazine 11.

[0059] It is understood that one or more of the trigger sections 121 and the limiting sections 122 may be provided with a guide surface for contact guidance if required.For example, one or more of the trigger sections 121 and the limiting sections 122 can be provided with a spherical, convex structure, so that it is possible to avoid damage to the contact surface by scratching between the staple sliding element 13 and the trigger section 121 when the staple sliding element 13 comes into contact with the trigger section 121, and it is possible to avoid damage to the contact surface by scratching between the limiting section 122 and the staple magazine holder 2 when the limiting section 122 comes into contact with the staple magazine holder 2, thereby extending the service life of the staple sliding element 13 and the elastic limiting unit 12 and reducing the probability of unwanted noise and abrasion due to scratching.

[0060] In the present embodiment, a first groove-shaped structure 21 is arranged on the staple magazine holder 2. The staple magazine assembly 1 can be inserted into the first groove-shaped structure 21 along a defined direction, and the first section 12a, the second section 12b and the third section 12c are connected sequentially along the defined direction.

[0061] The specified direction is from front to back. Specifically, the clamp magazine assembly 1 is moved from front to back and placed into the first groove-shaped structure 21, and the first section 12a, the second section 12b, and the third section 12c are distributed sequentially from front to back. As shown in Fig. 2 and Fig. As shown in Figure 6, one end of the third section 12c forms the limiting section 122 and the other end the release section 121. When the staple magazine assembly 1 needs to be pushed from front to back into the first groove structure 21, the limiting section 122 at the end of the third section 12c protrudes from the outer surface of the staple magazine assembly 1 in the left and right directions, for example from the outer surface of the staple magazine housing 14, and the front end face of the first groove-shaped structure 21 of the staple magazine seat 2 rests against the limiting section 122.While the staple magazine assembly 1 is pushed from front to back, the limiting section 122 tends to move forward under force and, at least in the initial stage, tends to expand outwards, making it more difficult to push the staple magazine assembly 1 from front to back into the first groove-shaped structure 21 to achieve a better protective effect against misassembly.

[0062] In the present embodiment, the clamp magazine housing 14 optionally presses the fastening end of the spring sheet structure tightly against the end face of the outer end of the mounting opening 111.

[0063] As in Fig.As shown in Figure 2, the inner surface of the staple magazine housing 14 presses the first section 12a tightly onto the end face of the outer end of the mounting opening 111 in the left and right directions and holds the plug section 12d inserted in the plug slot 113, thereby ensuring a reliable connection between the spring sheet structure and the staple magazine 11.

[0064] It is understood that the clamp magazine 11 may have a receiving groove on the end face of the outer end of the mounting opening 111, wherein the receiving groove is able to receive the spring sheet structure, for example a receiving groove for receiving the first section 12a.

[0065] Optionally, the inner surface of the mounting opening 111 can be designed as an inclined surface along the arrangement direction of the first section 12a, the second section 12b, and the third section 12c. This inclined surface comes into contact with the second section 12b or the third section 12c to define their end positions.

[0066] In the present embodiment, the first side walls 112 of the staple magazine 11 are optionally each provided with a mounting opening 111 along the width direction. For example, the two mounting openings 111 are arranged symmetrically in the left and right directions. To prevent incorrect assembly, the left and right sides of the staple magazine assembly 1 can each be blocked by one of the two limit sections 122, thus balancing the force distribution and preventing uneven force application on the left and right sides that could damage the staple magazine assembly 1, thereby ensuring high reliability.

[0067] It is understood that the structure of the elastic boundary unit 12 described above is merely exemplary, but is not limited to it.

[0068] Optionally, in the design of the spring sheet structure, the end of the second section 12b furthest from the first section 12a can be connected between the two ends of the third section 12c.

[0069] Optionally, both the release section 121 and the limiting section 122 can be designed as sliding elements, with the sliding elements sliding along the depth direction of the mounting opening 111 (e.g., in the left and right directions) to be attached to the clamp magazine 11.
