Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a skin stapler suitable for steering suturing. Background Art

[0002] Widely used skin staplers in the prior art are monolithic, disposable devices that cannot accommodate all wounds. Doctors maintain a fixed position relative to the patient when suturing wounds, leading to difficulties with the suturing angle of some wounds. Furthermore, some wounds may fail due to the doctor's inability to monitor the suturing progress. To address this issue, skin staplers with rotatable staple cartridges relative to the body of the device have been developed. Specifically, the staple cartridge housing and the body of the device are no longer integral, but rather separate components.

[0003] For example, Publication No. CN212438725U discloses a skin stapler with a rotatable and countable staple cartridge assembly. The device generally comprises a gun body assembly, a rotating staple cartridge assembly, a counter, and a rotating dial. The rotating staple cartridge assembly is mounted to the gun body assembly via the rotating dial and can rotate 360 ​​degrees. This structure allows the user to adjust the field of view during suturing by rotating the staple cartridge assembly, thereby reducing the difficulty of the suturing procedure. While the staple cartridge assembly of this skin stapler can rotate relative to the gun body assembly, it requires a separate rotating dial structure between the gun body and staple cartridge assemblies. The rotating dial then engages with both the gun body and staple cartridge assemblies to achieve rotational engagement. This structure also complicates the assembly process. As a disposable medical device, its production cost directly impacts the cost of surgery for patients. Therefore, reducing the production cost of the device can directly reduce the cost of treatment for patients. Therefore, while ensuring that the staple cartridge assembly can rotate relative to the gun body assembly, it is also necessary to maintain structural simplicity to reduce production costs. Summary of the Invention

[0004] The object of the present invention is to provide a skin stapler suitable for steering suturing, so as to solve the technical problem of achieving rotational cooperation between a staple cartridge and a gun body of the skin stapler through a simplified structure.

[0005] The skin stapler suitable for steering suturing of the present invention is achieved as follows:

[0006] A skin stapler suitable for steering suturing comprises: an outer shell, a staple plate arranged in the outer shell, and a connecting rod transition assembly connected to the staple plate;

[0007] The outer shell includes a nail magazine shell and a device body shell that are rotatably matched; the nail forming plate is arranged in the nail magazine shell; a male connector is formed on the device body shell, and a female adapter groove for matching the male connector is provided in the nail magazine shell;

[0008] The connecting rod transition assembly includes a third connecting rod connected to the nail plate, a second connecting rod connected to the third connecting rod at one end, and a first connecting rod connected to the other end of the second connecting rod;

[0009] A portion of the third connecting rod is inserted into the nail magazine housing, and another portion of the third connecting rod is inserted into the device body housing; the third connecting rod is in sliding fit with both the nail magazine housing and the device body housing;

[0010] The first connecting rod and the second connecting rod are both built into the body shell, and the first connecting rod and the second connecting rod are respectively slidably matched with the body shell; and the end of the first connecting rod away from the second connecting rod is also connected to the firing handle provided on the body shell.

[0011] In an optional embodiment of the present invention, at least one matching concave-convex positioning structure for relative rotation is provided between the male connector and the female adapting groove.

[0012] In an optional embodiment of the present invention, the concave-convex positioning structure includes a circular ring-shaped limiting protrusion provided on the outer wall of the male connector and a circular limiting groove formed on the groove wall of the female adapter groove.

[0013] In an optional embodiment of the present invention, the male connector is a cylindrical structure; and a cylindrical hollow groove is formed in the female adapter groove.

[0014] In an optional embodiment of the present invention, a first elastic member is further provided between the end of the first connecting rod away from the second connecting rod and the body shell.

[0015] In an optional embodiment of the present invention, the nail forming plate and the third connecting rod are connected in an L-shape; and

[0016] A second elastic member is further provided between the end portion of the third connecting rod connected to the nail plate and the inner wall of the nail magazine shell.

[0017] In an optional embodiment of the present invention, the end of the first connecting rod away from the second connecting rod is provided with a connecting hole for connecting to the firing handle; and

[0018] The firing handle is provided with a shift block suitable for being inserted into the connecting hole.

[0019] In an optional embodiment of the present invention, the first connecting rod has one end connected to the second connecting rod and is provided with a first U-shaped connector, and the third connecting rod has one end connected to the second connecting rod and is provided with a second U-shaped connector; and

[0020] The second connecting rod is rotatably connected to the first U-shaped connecting head and the second U-shaped connecting head through a pin shaft respectively.

[0021] In an optional embodiment of the present invention, a first stopper assembly for limiting the two sides of the first U-shaped connector and a second stopper assembly for limiting the two sides of the second U-shaped connector are provided in the body shell.

[0022] In an optional embodiment of the present invention, the end of the staple plate away from the third connecting rod is provided with a staple groove for accommodating a suture staple.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects: the skin stapler suitable for steering suturing of the present invention, first, the body shell and the nail magazine shell itself are a split structure, and the two are achieved by the cooperation of the male connector and the female adapter groove to achieve rotational cooperation between the two, and then at least one matching concave-convex positioning structure with relative rotation is provided between the male connector and the female adapter groove to achieve rotational cooperation between the body shell and the nail magazine shell without the problem of mutual separation. Under such a structure, the male connector is directly integrally formed in the production process of the body shell, and the female adapter groove is directly integrally formed in the production process of the nail magazine shell, so that the rotational cooperation between the body shell and the nail magazine shell can be achieved. The outer shell structure under this structure is simple, and the production and assembly are extremely simple, so the production cost of the skin stapler can be greatly reduced. Therefore, the skin stapler suitable for steering suturing of the present invention can achieve rotational cooperation between the nail magazine and the gun body of the skin stapler through a simplified structure. Furthermore, by rotating the staple cartridge housing relative to the body housing, the skin stapler of the present invention can adapt to the shape of the wound, thereby improving the operating comfort of medical personnel and the safety of the suturing operation, while at the same time exposing the suturing field of view to the greatest extent, thereby improving the convenience of the suturing operation of medical personnel.

[0024] Furthermore, the connecting rod transition assembly is connected to the nail plate, and then the connecting rod transition assembly is fired through the firing handle. Based on this structure, the firing handle does not need to directly fire the nail plate to achieve the pushing operation of the suture nail. Under such a structure, on the one hand, based on the situation that the nail magazine shell and the body shell are split structures, the traditional method of directly firing the nail plate through the firing handle is not applicable. Therefore, the connecting rod transition assembly is used to transmit the force of the firing handle, which can achieve compatibility with the split outer shell. On the other hand, the firing handle and the nail plate can maintain a certain distance under the action of the connecting rod transition assembly, leaving operating space for medical staff to hold the firing handle, thereby avoiding the problem of blocking the surgical suture field caused by the medical staff's hand-held operation.

DETAILED DESCRIPTION

[0036] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 10 As shown, this embodiment provides a skin stapler suitable for steerable suturing, comprising an outer housing, a staple forming plate disposed within the outer housing, and a connecting rod transition assembly connected to the staple forming plate. The outer housing comprises a staple cartridge housing 200 and a device body housing 100 that are rotatably engaged; the staple forming plate 1 is disposed within the staple cartridge housing 200.

[0038] Specifically, in order to achieve the rotational fit between the cartridge housing 200 and the body housing 100, this embodiment has the following designs:

[0039] The body housing 100 is formed with a raised male connector 400, and the cartridge housing 200 is provided with a female adaptor slot 300 for receiving the male connector 400. Furthermore, at least one rotatable concave-convex positioning structure is provided between the male connector 400 and the female adaptor slot 300. This means that the body housing 100 and the cartridge housing 200 are rotationally engaged by the rotatable concave-convex positioning structure, preventing them from becoming detached.

[0040] Regarding the above structure, it should be noted that the male connector 400 can be directly integrally formed on the device body shell 100 . Similarly, the female adapter groove 300 can also be directly integrally formed in the nail magazine shell 200 .

[0041] To facilitate assembly of the male connector 400 with the female adapter groove 300, the gun body housing 100 in this embodiment includes a left half-gun body 101 and a right half-gun body 102. The left half-gun body 101 is provided with a left male connector, while the right half-gun body 102 is provided with a right male connector. The left and right male connectors are assembled to form the male connector 400. Similarly, the cartridge housing 200 includes a left half-gun body 201 and a right half-gun body 202. The left half-gun body 201 is provided with a left female adapter groove, while the right half-gun body 202 is provided with a right female adapter groove. The left and right female adapter grooves are assembled to form the female adapter groove 300. The female adapter groove 300 has an opening 303 on one side of the gun body housing 100 that communicates with the hollow groove 302. Based on this structure, the male connector 400 and the female adapter groove 300 can be assembled simultaneously during the process of assembling the left half gun body 101 and the right half gun body 102 and the left half nail magazine 201 and the right half nail magazine 202.

[0042] The left half nail magazine 201 and the right half nail magazine 202 in this embodiment can be fastened together by, for example, but not limited to, screws. Similarly, the left half gun body 101 and the right half gun body 102 in this embodiment can be fastened together by, for example, but not limited to, screws.

[0043] In an optional implementation, two concave-convex positioning structures are provided between the male connector 400 and the female adapter groove 300. The two concave-convex positioning structures can effectively ensure effective and stable cooperation between the male connector 400 and the female adapter groove 300.

[0044] Next, it will be explained that, in an optional implementation, the concave-convex positioning structure in this embodiment includes a circular-shaped limiting protrusion 401 provided on the outer wall of the male connector 400 and a circular-shaped limiting groove 301 formed on the groove wall of the female adapter groove 300. The drawings of this embodiment only take this case as an example. In another optional implementation, the concave-convex positioning structure includes a circular-shaped limiting groove 301 provided on the outer wall of the male connector 400 and a circular-shaped limiting protrusion 401 formed on the groove wall of the female adapter groove 300. Regardless of which of the above optional implementations is used, the groove wall of the limiting groove 301 in this embodiment is in sliding fit with the outer wall of the limiting protrusion 401.

[0045] In addition, it should be noted that the male connector 400 in this embodiment is a cylindrical structure; and a cylindrical hollow groove 302 is formed in the female adapter groove 300. The groove wall of the hollow groove 302 is in sliding fit with the outer wall of the male connector 400. The male connector 400 and the female adapter groove 300 in this shape can also realize the rotational support fit between the nail magazine shell 200 and the device body shell 100. On the basis of this structure, it is necessary to explain that in order to avoid the sliding contact between the male connector 400 and the female adapter groove 300 being too smooth, thereby causing unexpected rotation between the nail magazine shell 200 and the device body shell 100, this embodiment can set a certain friction resistance on the contact surface between the groove wall of the hollow groove 302 and the outer wall of the male connector 400, so as to reduce the occurrence of unexpected rotation.

[0046] That is to say, the rotational cooperation between the male connector 400 and the female adapter groove 300 is not only between the concave and convex positioning structures, but also between the male connector 400 itself and the hollow groove 302. In this way, the contact area for the rotational cooperation between the overall male connector 400 and the female adapter groove 300 is larger, which can effectively improve the stability of the nail magazine shell 200 and the device body shell 100 in the cooperation state, thereby improving the reliability of the skin stapler in use.

[0047] Next, let’s talk about the connecting rod transition assembly:

[0048] The connecting rod transition assembly includes a third connecting rod 6 connected to the nail plate 1 , a second connecting rod 5 connected to the third connecting rod 6 at one end, and a first connecting rod 4 connected to the other end of the second connecting rod 5 .

[0049] It should be noted that, in this embodiment, the first connecting rod 4 is provided with a first U-shaped connector 42 at one end for connecting to the second connecting rod 5, and the third connecting rod 6 is provided with a second U-shaped connector 61 at one end for connecting to the second connecting rod 5; and the second connecting rod 5 is rotatably connected to the first U-shaped connector 42 and the second U-shaped connector 61 through a pin shaft respectively.

[0050] In more detail, a portion of the third connecting rod 6 is inserted into the staple magazine housing 200 of the skin stapler, and another portion of the third connecting rod 6 is inserted into the body housing 100; the third connecting rod 6 is in sliding fit with both the staple magazine housing 200 and the body housing 100; the first connecting rod 4 and the second connecting rod 5 are both built into the body housing 100, and the first connecting rod 4 and the second connecting rod 5 are respectively in sliding fit with the body housing 100; and the end of the first connecting rod 4 away from the second connecting rod 5 is also connected to the firing handle 82 provided on the body housing 100. It should be noted that since a part of the third connecting rod 6 is inserted into the body shell 100 and the other part is inserted into the nail magazine shell 200, in order to ensure that the cooperation between the male connector 400 and the female adapter groove 300 does not affect the simultaneous connection of the third connecting rod 6 with the nail magazine shell 200 and the body shell 100, the male connector 400 in this embodiment is built with a through hole suitable for the third connecting rod 6 to pass through. The inner diameter of the through hole can be selected to be larger than the outer diameter of the third connecting rod 6, so that the male connector 400 will not affect the sliding of the third connecting rod 6 between the nail magazine shell 200 and the body shell 100, and when the female adapter groove 300 rotates relative to the male connector 400, it will not affect the third connecting rod 6.

[0051] The connecting rod transition assembly is used here to transmit the force acting on the firing handle 82. Under such a structure, that is, when the medical staff grasps the firing handle 82 with their hands, the firing handle 82 transmits the force acting on the nail plate 1 through the connecting rod transition assembly, thereby causing the nail plate 1 to have a pushing effect on the suture staples 9. Under such a structure, that is, by controlling the length of the first connecting rod 4 directly connected to the firing handle 82, the distance between the firing handle 82 and the nail plate 1 can be effectively controlled. In other words, the firing handle 82 and the nail plate 1 can maintain a certain distance under the action of the connecting rod transition assembly, leaving operating space for the medical staff to hold the firing handle 82, thereby avoiding the problem of the medical staff's hand-held operation blocking the surgical suturing field.

[0052] On the basis of the above structure, it is necessary to explain that, considering the reset problem of the nail plate 1 and the connecting rod transition assembly, this embodiment also has the following structural design:

[0053] First, a first elastic member 71 is provided between the end of the first connecting rod 4 away from the second connecting rod 5 and the body shell 100. One end of the first elastic member 71 is hooked to the inner wall of the body shell 100, and the other end is hooked to the first connecting rod 4. The first elastic member 71 here can be a spring.

[0054] Secondly, the nail plate 1 and the third connecting rod 6 are connected in an L-shaped manner, and a second elastic member 72 is provided between the end of the third connecting rod 6 connected to the nail plate 1 and the inner wall of the nail magazine housing 200. The second elastic member 72 here can be a spring.

[0055] For the above-mentioned first elastic member 71 and second elastic member 72, during the process of firing the suture nail 9, the first elastic member 71 is gradually stretched and deformed, while the second elastic member 72 is gradually compressed and deformed. Therefore, during the reset process after the firing is completed, the reset of the nail plate 1 and the connecting rod transition assembly is quickly achieved through the reset of the first elastic member 71 and the second elastic member 72, so as to perform the firing operation of the next suture nail 9.

[0056] In addition, in order to facilitate the limitation of the movement trajectory of the connecting rod transition assembly, this embodiment also makes the following design:

[0057] First, the housing 100 is further provided with at least one limiting bracket 31 for limiting the position of the first connecting rod 4, and each limiting bracket 31 is prefabricated with a limiting groove 32 that fits the first connecting rod 4. It should be noted that the limiting bracket 31 and limiting groove 32 are respectively formed in the left half of the gun body 101 and the right half of the gun body 102.

[0058] Secondly, the magazine housing 200 is also provided with at least one retaining seat 21 for retaining the third connecting rod 6. Each retaining seat 21 is prefabricated with a retaining hole 22 that mates with the third connecting rod 6. The retaining seat 21 and retaining hole 22 are formed in the left and right magazine halves 201 and 202, respectively. It should be noted that the retaining seat 21 can be provided independently within the magazine housing 200, or directly on a side wall of the female adapting groove 300, as shown in the accompanying drawings. Both arrangements meet the requirements of this embodiment. In this embodiment, the retaining seat 21 is formed directly on the side wall of the female adapting groove 300 facing away from the body housing 100. This allows the third connecting rod 6, which has passed through the through hole of the male connector 400, to pass directly through the retaining hole 22 of the retaining seat 21. This ensures that the connecting rod transition assembly, the male connector 400, and the female adapting groove 300 function seamlessly, each independently performing its respective functions without interfering with the other.

[0059] Furthermore, the housing 100 is provided with a first stopper assembly 33 for limiting the positions of both sides of the first U-shaped connector 42 and a second stopper assembly 34 for limiting the positions of both sides of the second U-shaped connector 61. In this embodiment, the first stopper assembly 33 and the second stopper assembly 34 each include a pair of stoppers that are arranged opposite to each other.

[0060] Next, we will explain the cooperation between the firing handle 82 and the first connecting rod 4:

[0061] First, the firing handle 82 is rotatably connected to the body shell 100 through the positioning column 81, so that the firing handle 82 can rotate around the positioning column 81.

[0062] Secondly, the end of the first connecting rod 4 away from the second connecting rod 5 is provided with a connecting hole 41 for connecting to the firing handle 82; and the firing handle 82 is provided with a shift block 83 suitable for inserting into the connecting hole 41. When the firing handle 82 is gripped by the hand, the shift block 83 can move in the connecting hole 41. When the shift block 83 moves to the hole wall of the connecting hole 41 facing the nail magazine housing 200, the firing handle 82 can generate a pushing effect on the first connecting rod 4, and the first connecting rod 4 then transmits the pushing effect to the nail plate 1 through the second connecting rod 5 and the third connecting rod 6.

[0063] Finally, the nail forming plate 1 to be described has a nail groove 16 for accommodating a suture nail 9 at its end away from the third connecting rod 6. Preferably, the nail groove 16 is a U-shaped groove.

[0064] More specifically, a deformation groove 11 is formed at the end of the nail plate 1 away from the third connecting rod 6, and the deformation groove 11 forms a left pressure nail tooth 12 and a right pressure nail tooth 13. A nail groove 16 is formed on the left pressure nail tooth 12 and the right pressure nail tooth 13, respectively. The bottom of the deformation groove 11 is provided with an inclined surface that can push the deformed suture staple 9 forward. When using this skin stapler, the firing handle 82 is pressed. Under the action of the connecting rod transition assembly, the suture staple 9 in the staple cartridge is squeezed by the left pressure nail tooth 12 and the right pressure nail tooth 13. During the squeezing process, the suture staple 9 continuously bends toward the interior of the deformation groove 11, and the two ends gradually converge. After the suture staple 9 is completely collapsed, the back side of the suture staple 9 contacts the inclined surface at the bottom of the deformation groove 11, thereby pushing the deformed suture staple 9 forward. Due to this design, when the suture staple 9 is squeezed to the point where the deformation is complete, it can slide forward smoothly along the inclined surface out of the track and out of the staple cartridge. This effectively avoids the feeling of stagnation caused by the pressure nail and makes the suture staple 9 eject more smoothly.

[0065] The above-mentioned inclined surface can be directly formed on the bottom of the deformed groove 11. Preferably, a wedge-shaped protrusion 14 is provided on the bottom of the deformed groove 11, and the end face of the wedge-shaped protrusion 14 forms an inclined surface, that is, the wedge-shaped protrusion 14 provides a thrust to push the suture nail 9 forward.

[0066] In an optional implementation, a structural groove 15 is opened in the middle of the groove bottom of the deformation groove 11 , and wedge-shaped protrusions 14 are provided on both sides of the structural groove 15 at the groove bottom of the deformation groove 11 .

[0067] The nail plate 1 can be formed of materials such as metal and composite materials. Preferably, the sheet 1 is formed of a rectangular sheet, and a deformation groove 11 is opened in the center of the end of the sheet 1, thereby forming symmetrically distributed left nail pressing teeth 12 and right nail pressing teeth 13 at the end of the sheet 1, which is convenient for aligning the suture nail 9.

[0068] In order to facilitate the deformation of the suture staple 9 , the corners of the left pressing staple tooth 12 and the right pressing staple tooth 13 are both rounded.

[0069] In summary, the skin stapler of this embodiment, which is suitable for steerable suturing, can achieve rotational coordination between the staple cartridge and the body of the skin stapler using a simplified structure. Furthermore, by rotating the staple cartridge housing relative to the body of the device, the skin stapler of the present invention can adapt to the shape of the wound, thereby improving the safety of the suturing operation and maximizing the exposure of the suturing field, thereby increasing the convenience of the suturing operation for medical personnel.

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0075] In the present invention, unless otherwise expressly specified or limited, a first feature being above or below a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being above, above, and above the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being below, below, and below the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
