Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a suturing device. Background Art

[0002] Suturing is the process of reconnecting or reconstructing tissues and organs that have been cut or ruptured by trauma to restore their function. It is essential for proper healing and is one of the most important basic surgical techniques. Different methods and approaches are used for suturing tissues and organs in different locations.

[0003] Conventional staplers include an outer sleeve, a housing coaxially connected to the outer sleeve, a puncture needle axially movable within the outer sleeve, and a drive mechanism connected to the puncture needle for driving the puncture needle. The drive mechanism, located within the housing, drives the puncture needle in an axial reciprocating motion, advancing and retracting the needle. However, using a power mechanism such as a cylinder or a screw motor not only complicates the structure of the stapler and significantly increases its cost, but also results in a larger housing. Summary of the Invention

[0004] Based on this, the purpose of the present application is to provide a stapler that can simplify the structure, reduce costs, and at the same time has a smaller shell size.

[0005] A stapler comprising: an outer sleeve, a housing connected to the outer sleeve, and a puncture needle movably disposed axially within the outer sleeve; the stapler further comprising a drive mechanism for driving the puncture needle forward and backward axially, the drive mechanism comprising:

[0006] a pushing member connected to the puncture needle and axially movably disposed inside the housing;

[0007] a gripping handle, the gripping handle being located outside the shell and having a hinged end and a free end, the hinged end being rotatably connected to the shell, and the free end adaptively moving closer to or farther from the shell according to changes in gripping force; and

[0008] A connecting rod, one end of which is rotatably connected to the holding handle, and the other end of which is rotatably connected to the pushing member. When the free end approaches or moves away from the shell, the holding handle causes the connecting rod to drive the pushing member to move in the direction of needle insertion or withdrawal, thereby causing the pushing member to drive the puncture needle to advance or withdraw the needle.

[0009] In one embodiment, a movable groove is formed on the shell, and the connecting rod can be movably inserted into the movable groove.

[0010] In one embodiment, the suturing device further includes a reset member, which is connected to the pushing member and the housing, respectively, and is used to reset the pushing member from the needle insertion position to the needle withdrawal position.

[0011] In one embodiment, there are two gripping handles and two connecting rods, which are provided in one-to-one correspondence, and the two gripping handles are respectively arranged on opposite sides of the shell.

[0012] In one embodiment, each of the gripping handles is formed with a receiving groove for receiving the shell;

[0013] When the two gripping handles are pressed and the free ends of the corresponding two gripping handles are moved to the extreme position close to the shell, the two gripping handles reach the closed position respectively, and the opposite sides of the shell are respectively accommodated in the two accommodating grooves.

[0014] In one embodiment, grooves are formed on the sides of the two gripping handles facing each other.

[0015] In one embodiment, one end of the gripping handle is provided with a first axial hole and a first connecting member rotatably inserted into the first axial hole, and the first connecting member is connected to the shell; and / or a mounting groove is formed on the inner wall of the gripping handle, and one end of the connecting rod extends into the mounting groove and is rotatably arranged in the mounting groove.

[0016] In one embodiment, the mounting groove extends in an axial direction parallel to the gripping handle; a second axial hole and a second connecting member rotatably inserted into the second axial hole are provided on one end of the connecting rod, and the opposite ends of the second connecting member are respectively connected to the opposite side walls of the mounting groove.

[0017] In one embodiment, an anti-slip structure is provided on the outer wall of the gripping handle; the anti-slip structure includes anti-slip protrusions and / or anti-slip lines.

[0018] In one embodiment, a gripping area and a protrusion protruding from the gripping area are formed on an outer wall of the gripping handle, and the protrusion is arranged at a proximal end of the gripping area.

[0019] When using the above-mentioned suturing device, by pressing the gripping handle to move the free end of the gripping handle toward the direction close to the housing, the gripping handle drives the connecting rod to move, and the connecting rod drives the pusher to move toward the distal end of the outer sleeve, thereby enabling the puncture needle to be inserted in the axial direction. It can be seen that there is no need to use a power mechanism such as a cylinder or a motor screw disposed inside the housing to achieve the axial movement of the pusher. Using the gripping handle and the connecting rod as the power mechanism to drive the axial movement of the pusher can simplify the structure and reduce costs. At the same time, by gripping the gripping handle to achieve needle insertion, the operation is convenient, the user can intuitively feel the needle insertion situation, and it is more conducive to the control of the suturing process.

[0028] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it is still necessary to explain that the proximal end refers to the end of the instrument or component close to the operator, and the distal end refers to the end of the instrument or component away from the operator; the axial direction refers to the direction parallel to the line connecting the distal and proximal ends of the instrument or component, the radial direction refers to the direction perpendicular to the axial direction, and the circumferential direction refers to the direction surrounding the axial direction.

[0030] It should also be noted that the related technologies in the background technology of this application are only for the convenience of explaining the technical problems to be solved by this application, and the related technologies do not necessarily belong to the existing technology.

[0031] See Figures 1 to 3 , Figure 1 and Figure 2 The structural diagrams respectively show the gripping handle 30 of the stapler according to one embodiment of the present application in a loosened state and a gripping state. Figure 3 An exploded structural diagram of a stapler according to one embodiment of the present application is shown. One embodiment of the present application provides a stapler comprising an outer sleeve 10, a housing 20 connected to the outer sleeve 10, and a puncture needle axially movably disposed within the outer sleeve 10. The stapler also includes a drive mechanism for driving the puncture needle axially forward and backward. The drive mechanism comprises a pusher, a gripping handle 30, and a connecting rod 40. The pusher is connected to the puncture needle and axially movably disposed within the housing 20. The gripping handle 30 is located outside the housing 20 and has a hinged end and a free end. The hinged end is rotatably connected to the housing 20. The free end adaptively moves closer to or further away from the housing 20 based on changes in gripping force. One end of the connecting rod 40 is rotatably connected to the gripping handle 30, and the other end is rotatably connected to the pusher. When the free end moves closer to or further away from the housing, the gripping handle 30 causes the connecting rod 40 to drive the pusher in the needle advancement or withdrawal direction, thereby causing the pusher to advance or withdraw the puncture needle.

[0032] Specifically, a movable groove 21 is formed on the housing 20, and the connecting rod 40 is movably inserted into the movable groove 21. When the gripping handle 30 is pressed to move the free end of the gripping handle 30 toward the housing 20, the connecting rod 40 is moved. Figure 1 The state shown moves to Figure 2 Status shown, or from Figure 4 The state shown moves to Figure 5In the state shown, the gripping handle 30 drives the connecting rod 40 to move, and the connecting rod 40 drives the pushing member to move toward the distal end of the outer sleeve 10, and the pushing member can drive the puncture needle to advance along the axial direction.

[0033] It should be noted that the axial direction in this embodiment refers to Figure 1 or Figure 4 The direction shown is Z.

[0034] When using the above-mentioned suturing device, by pressing the gripping handle 30 so that the free end of the gripping handle 30 moves in a direction close to the housing 20, the gripping handle 30 drives the connecting rod 40 to move, and the connecting rod 40 drives the pusher to move toward the distal end of the outer sleeve 10, thereby enabling the puncture needle to be inserted in the axial direction. As can be seen from this, it is not necessary to use a power mechanism such as a cylinder or a motor screw disposed inside the housing 20 to achieve the axial movement of the driving member. Using the gripping handle 30 and the connecting rod 40 as the power mechanism for driving the axial movement of the pushing member can simplify the structure and reduce costs. At the same time, by gripping the gripping handle to achieve needle insertion, the operation is convenient, the user can more intuitively feel the needle insertion situation, and is more conducive to the control of the suturing process.

[0035] It should be noted that the gripping handle 30 may or may not have a finger-passing area, and this is not limited here. In some optional solutions, the gripping handle 30 may have a finger-passing area, that is, the gripping handle 30 may be configured similarly to a scissor handle, which facilitates tightening or loosening of the grip.

[0036] In one embodiment, the suturing device further includes a reset member. The reset member is connected to the push member and the housing 20 respectively, and the reset member is used to reset the push member from the needle insertion position to the needle withdrawal position. Specifically, the reset member includes but is not limited to an elastic reset member, such as a spring, an elastic strip or an elastic rope, etc., as long as the push member can be reset from the needle insertion position to the needle withdrawal position. In this way, on the one hand, by pressing the gripping handle 30 to the closed state, the gripping handle 30 moves the push member from the needle withdrawal position to the needle insertion position through the connecting rod 40, and the reset member can be deformed to store elastic potential energy at the same time; on the other hand, after releasing the gripping handle 30, the reset force of the reset member can reset the push member from the needle insertion position to the needle withdrawal position, and at the same time, the gripping handle 30 is reset to the open state, that is, from Figure 2 The state shown moves to Figure 1 Status shown, or from Figure 5 The state shown moves to Figure 4 Status shown.

[0037] In some specific embodiments, the movable groove 21 extends axially, thereby providing axial movement space for the connecting rod 40. Specifically, the movable groove 21 can also slide with the connecting rod 40, guiding the rotation of the connecting rod 40. This prevents the connecting rod 40 from shifting to either side when the gripping handle 30 is pressed, making the pressing action more stable and reliable. In addition, the distal end of the gripping handle 30 is rotatably connected to the housing 20, and the proximal end of the gripping handle 30 is rotatably connected to the proximal end of the connecting rod 40. The gripping handle 30 and the connecting rod 40 are arranged at an acute angle, and the distal end of the connecting rod 40 is rotatably connected to the pusher and arranged at an angle. When the gripping handle 30 is pressed, the gripping handle 30 drives the proximal end of the connecting rod 40 to move, so that the distal end of the connecting rod 40 drives the pushing member to move along the axial direction toward the distal end of the outer sleeve 10, thereby driving the puncture needle to advance; conversely, when the gripping handle 30 is released, under the action of the resetting force of the resetting member, the puncture needle, the pushing member and the gripping handle 30 are reset.

[0038] In some embodiments, the number of gripping handles 30 is at least one, including but not limited to one, two, three, four, or more, which can be flexibly adjusted and configured based on actual needs. When there are multiple gripping handles 30, all gripping handles 30 are evenly spaced around the circumference of the housing 20, and multiple connecting rods 40 are correspondingly provided, each corresponding to a gripping handle 30. This allows for synchronous and balanced force application across all parts of the pusher during gripping, resulting in more stable and reliable axial movement.

[0039] See also Figures 1 to 3 In one embodiment, two gripping handles 30 and two connecting rods 40 are provided in a one-to-one correspondence, with the two gripping handles 30 being disposed on opposite sides of the housing 20. This not only provides an appropriate number of gripping handles 30, but also facilitates the gripping operation. Furthermore, during gripping, the various parts of the pusher are simultaneously stressed, resulting in a more balanced force and more stable and reliable axial movement.

[0040] See also Figure 3 and Figure 7In one embodiment, each gripping handle 30 is formed with a receiving groove 31 for receiving the shell 20. When the two gripping handles 30 are pressed and the free ends of the corresponding two gripping handles 30 are moved to the extreme position close to the shell, the two gripping handles 30 reach the closed position respectively, and the opposite sides of the shell 20 are respectively received in the two receiving grooves 31. Specifically, when the two gripping handles 30 are in the closed position, the two gripping handles 30 include but are not limited to directly abutting each other, and both free ends abut against each other, for example, with the shell 20. In this embodiment, when the two gripping handles 30 are in the closed position, the two gripping handles 30 abut against each other are used as an example for expansion. Since the two gripping handles 30 abut against each other, it is impossible to continue pressing, which means that the pressing action is completed, and the puncture needle is inserted once. In addition, since the opposite sides of the shell 20 are received in the two receiving grooves 31, the overall structure is compact and the overall volume size can be reduced.

[0041] In addition, when the two gripping handles 30 are released, the pusher can be reset from the needle insertion position to the needle withdrawal position under the action of the reset force of the reset member, and the gripping handles 30 can be reset to the open position at the same time, that is, the free ends of the two gripping handles 30 move to the extreme position away from the housing 20. For details, see Figure 2 The state shown moves to Figure 1 Status shown, or from Figure 5 The state shown moves to Figure 4 Status shown.

[0042] See also Figure 2 、 Figure 5 and Figure 6 In some embodiments, when the two gripping handles 30 are moved to the closed position, the cross-sectional profile of the integral structure formed by the two gripping handles 30 along the axial direction includes but is not limited to a flat square (such as Figure 6 As shown in the figure), waist-shaped, oval or round and other regular shapes and other irregular shapes. In this way, the outer contour of the overall structure does not hurt the hand during holding, and it is easy to hold and operate.

[0043] See also Figure 3 In some embodiments, the receiving groove 31 of each gripping handle 30 is adapted to the shape of the outer side wall of the shell 20, thereby facilitating a reduction in the overall volume size.

[0044] See also Figure 1 and Figure 2In one embodiment, grooves 32 are formed on the sides of the two gripping handles 30 facing each other. Specifically, the grooves 32 include, but are not limited to, the middle portion of the sides of the gripping handles 30. Thus, when the two gripping handles 30 are moved to the closed position and a jam occurs, the grooves 32 of the two gripping handles 30 can serve as a force application point. For example, a finger can be inserted into the grooves 32 to facilitate the prying of the two gripping handles 30, thereby facilitating the opening of the two gripping handles 30 and forcing the needle out.

[0045] See also Figure 3 and Figure 7 In one embodiment, one end of the gripping handle 30 is provided with a first shaft hole 33 and a first connecting member 34 rotatably inserted into the first shaft hole 33, and the first connecting member 34 is connected to the housing 20. In this way, one end of the gripping handle 30 can be rotatably connected to the housing 20.

[0046] Specifically, the housing 20 is provided with a first mounting hole 22 corresponding to the position of the first shaft hole 33. The first connecting member 34 is also passed through the first mounting hole 22 and connected to the housing 20.

[0047] Optionally, the first connecting member 34 includes but is not limited to a pin, a rivet, a connecting shaft, etc.

[0048] In some embodiments, the handle 30 is provided with two first axial holes 33, which are located on opposite sides of the handle 30 and are symmetrically arranged about the axis of the handle 30. There are two first connecting members 34, which are correspondingly arranged to the two first axial holes 33 of the handle 30.

[0049] In some embodiments, the distal end of the handle 30 is rotatably connected to the outer wall of the housing 20 using, but not limited to, a pin or a connecting shaft. Specifically, opposite sides of the distal end of the handle 30 are each rotatably connected to the outer wall of the housing 20 using a pin or a connecting shaft. Similarly, the handle 30 is rotatably connected to the end of the connecting rod 40 using, but not limited to, a pin or a connecting shaft.

[0050] In one embodiment, a mounting groove 35 is formed on the inner wall of the handle 30, into which one end of the connecting rod 40 extends and is rotatably mounted. Specifically, the mounting groove 35 is formed on the bottom wall of the receiving groove 31. This ensures a more stable rotational connection between the end of the connecting rod 40 and the handle 30.

[0051] In one embodiment, the mounting groove 35 extends in an axial direction parallel to the handle 30. A second axial hole 41 is defined at one end of the connecting rod 40, and a second connecting member 42 is rotatably inserted into the second axial hole 41. The opposite ends of the second connecting member 42 are respectively connected to the opposite side walls of the mounting groove 35.

[0052] Specifically, opposite second mounting holes 351 are formed on two opposite side walls of the mounting slot 35 , and opposite ends of the second connecting member 42 are correspondingly mounted in the two second mounting holes 351 .

[0053] In some embodiments, the second connecting member 42 includes but is not limited to a pin or a connecting shaft, and can be flexibly adjusted and set according to actual needs.

[0054] In one embodiment, the outer wall of the grip 30 is provided with an anti-slip structure 36. Specifically, the anti-slip structure 36 includes, but is not limited to, at least one of anti-slip protrusions and anti-slip lines. This provides a good anti-slip effect when gripping the grip 30, preventing the grip from slipping during the pressing operation.

[0055] In some embodiments, the outer wall of the housing 20 is provided with axially extending reinforcing ribs or protrusions to strengthen the structure of the housing 20. A clearance groove 37 corresponding to the position of the reinforcing ribs or protrusions is formed on the handle 30. When the handle 30 is pressed to the closed position, the clearance groove 37 clears the reinforcing ribs or protrusions, preventing them from interfering with the handle 30.

[0056] In one embodiment, the outer wall of the grip 30 is formed with a gripping area and a protrusion 38 that protrudes from the gripping area. The protrusion 38 is located proximal to the gripping area. This protrusion 38 restricts the operator's gripping area and prevents the operator's hand from slipping off the grip. Furthermore, the proximal end of the housing 20 is provided with a knob 23, and the protrusion 38 is located on the side of the knob 23 that is closer to the distal end of the outer sleeve 10. Thus, when gripping the grip 30, the protrusion 38 acts as a limiter, preventing the palm from extending beyond the gripping area and accidentally touching the knob 23.

[0057] In some embodiments, the housing 20 or the handle 30 is provided with an indicator 24 for indicating the front and back sides of the stapler. Thus, during use, the indicator 24 can facilitate the user to distinguish the front and back sides of the stapler.

[0058] In some embodiments, the indicator portion 24 includes but is not limited to one or more combinations of patterns, numbers, convex dots, and concave portions, and may also be set to other marks according to actual needs, which is not limited here.

[0059] As an example, a window 11 is formed on the side wall of the distal end of the outer sleeve 10 , and the direction of the window 11 can be distinguished according to the indicator portion 24 , thereby facilitating surgical operations.

[0060] It should be noted that the "anti-slip structure 36" can be "a part of the gripping handle 30", that is, the "anti-slip structure 36" and the "other parts of the gripping handle 30" are integrally molded; it can also be an independent component that can be separated from the "other parts of the gripping handle 30", that is, the "anti-slip structure 36" can be manufactured independently and then combined with the "other parts of the gripping handle 30" into a whole.
