Description

Technical Field

[0001] This utility model relates to the field of surgical instruments, and in particular to a surgical clamp device and a surgical stapler. Background Technology

[0002] Anastomosing devices are commonly used in endoscopic surgery to replace traditional open surgical devices because smaller incisions often shorten postoperative recovery time and reduce complications. Therefore, a series of endoscopic surgical instruments have been developed to accurately place distal actuators at the surgical site through a cannula. These distal actuators have been introduced into the tissue in several ways to achieve diagnostic or therapeutic effects.

[0003] When using a stapler, the angle of the jaw assembly needs to be adjusted to suit different surgical sites. Therefore, existing staplers typically hinge the jaw assembly to the main body. To ensure the stability of the jaw assembly during use, a locking structure is required, such as the stapler described in Chinese Utility Model Patent CN101327141B, which uses a gear mechanism for locking. However, existing locking structures usually employ gear locking, which has a poor locking effect, making the jaw assembly prone to wobbling during use. Utility Model Content

[0004] The purpose of this invention is to provide a surgical clamp device and a surgical stapler to solve the above-mentioned technical problems.

[0005] In a first aspect, this utility model provides a surgical jaw device, comprising: a connecting sleeve, a mounting rod, an adjusting rod, a driving assembly, a jaw pull rod, and a jaw assembly. The jaw assembly is rotatably disposed at one end of the mounting rod, and the other end of the mounting rod is connected to the connecting sleeve. One end of the jaw pull rod is hinged to the jaw assembly, and the other end of the jaw pull rod is hinged to the adjusting rod. The end of the adjusting rod away from the jaw pull rod is driven to engage with the driving assembly. The driving assembly is used to drive the adjusting rod to move along the length direction and drive the jaw assembly to deflect via the jaw pull rod. After the jaw assembly deflects, the jaw assembly, the jaw pull rod, and the mounting rod form a triangular support structure.

[0006] Furthermore, the jaw assembly includes a rotating connecting block and an operating jaw. One end of the rotating connecting block is hinged to the mounting rod, and the operating jaw is located at the other end of the rotating connecting block, and the operating jaw rotates synchronously with the rotating connecting block.

[0007] Furthermore, the rotating connecting block is detachably connected to the operating jaws.

[0008] Furthermore, the angle between the jaw assembly after deflection and the extension direction of the mounting rod is the adjustment angle, which ranges from 0 to 60 degrees.

[0009] Furthermore, the hinge position between the mounting rod and the jaw assembly is the first hinge point, and the hinge position between the jaw lever and the adjusting rod is the second hinge point. When the adjustment angle of the jaw assembly is 60 degrees, the distance between the first hinge point and the second hinge point is equal to the length of the jaw lever.

[0010] Furthermore, a transverse limiting groove is provided on the mounting rod, and the adjusting rod is slidably set in the transverse limiting groove.

[0011] Furthermore, a travel limit component is provided on the mounting rod, which is used to limit the movement distance of the adjusting rod along the transverse limit groove.

[0012] Furthermore, the rotating connecting block is designed with an L-shaped structure.

[0013] Furthermore, the jaw assembly is equipped with anti-slip components.

[0014] On the other hand, this utility model also provides a surgical stapler, which includes: an operating handle and a surgical jaw device as described in any of the above, wherein the connecting sleeve of the surgical jaw device is rotatably connected to the operating handle.

[0028] Example 1

[0029] This embodiment provides a surgical jaw device, which includes: a connecting sleeve 100, a mounting rod 200, an adjusting rod 600, a driving assembly 300, a jaw pull rod 400, and a jaw assembly 500. The jaw assembly 500 is rotatably mounted on one end of the mounting rod 200, and the other end of the mounting rod 200 is connected to the connecting sleeve 100. One end of the jaw pull rod 400 is hinged to the jaw assembly 500, and the other end of the jaw pull rod 400 is hinged to the adjusting rod 600. The end of the adjusting rod 600 away from the jaw pull rod 400 is driven to engage with the driving assembly 300. The driving assembly 300 is used to drive the adjusting rod 600 to move along its length, and drives the jaw assembly 500 to deflect via the jaw pull rod 400. After the jaw assembly 500 deflects, the jaw assembly 500, the jaw pull rod 400, and the mounting rod 200 form a triangular support structure.

[0030] Please refer to Figure 1 As shown, in this embodiment, the mounting rod 200 is a hollow tubular structure, and a cable or controller for operating the jaw assembly 500 can be installed inside the mounting rod 200. One end of the mounting rod 200 is rotatably connected to the jaw assembly 500, and the other end of the mounting rod 200 is connected to the connecting sleeve 100. The connecting sleeve 100 can be connected to an external operating handle 700 or other medical devices, thereby connecting the surgical jaw device with other devices for surgical operations. A drive assembly 300 is provided on the connecting sleeve 100, and the drive assembly 300 is driven to cooperate with the adjusting rod 600, thereby adjusting the rotation angle of the jaw assembly 500. Specifically, a jaw pull rod 400 is provided at the connection between the jaw assembly 500 and the mounting rod 200. One end of the jaw pull rod 400 is hinged to the jaw assembly 500, and the rotation axis of the jaw assembly 500 and the jaw pull rod 400 is spaced apart from the rotation axis of the jaw assembly 500 and the mounting rod 200. The other end of the jaw lever 400 is connected to the adjusting rod 600, which engages with the drive assembly 300. The drive assembly 300 drives the adjusting rod 600 to move along its length. During this movement, the adjusting rod 600 pulls the jaw lever 400, causing the jaw assembly 500 to swing, forming an angle between the jaw assembly 500 and the mounting rod 200. In use, the rotation angle of the jaw assembly 500 can be adjusted to adapt to different operational needs in various environments, improving the overall practicality of the device. Please refer to... Figure 2 and Figure 3As shown, during the adjustment of the jaw assembly 500 angle, the jaw assembly 500, jaw lever 400, and mounting rod 200 form a triangular support structure. Under the action of the rotating connecting block 501 and the jaw lever 400, the stability of the jaw assembly 500 during use is ensured, preventing shaking or deflection during operation. It can be understood that the jaw lever 400 forms a relatively long support arm, which can fully support the rotating connecting block 501, preventing it from shaking. After the jaw assembly 500 is adjusted to a suitable angle, the support structure formed by the jaw lever 400 ensures that the jaw assembly 500 is maintained at the required angle, improving stability and safety during operation.

[0031] Optionally, in this embodiment, the drive assembly 300 can adopt an existing manual or electric drive structure to enable the adjustment rod 600 to move laterally, and the specific structure is not limited.

[0032] Optionally, in some embodiments of this example, the jaw assembly 500 includes a rotating connecting block 501 and an operating jaw 502. One end of the rotating connecting block 501 is hinged to the mounting rod 200, and the operating jaw 502 is disposed at the other end of the rotating connecting block 501, and the operating jaw 502 rotates synchronously with the rotating connecting block 501.

[0033] Please refer to Figure 1 As shown, in this embodiment, the operating jaws 502 are existing clamping jaws, and are rotatably connected to the mounting rod 200 via a rotating connecting block 501. One end of the rotating connecting block 501 is rotatably connected to the mounting rod 200, and the other end is hinged to the jaw pull rod 400. When the adjusting rod 600 moves, it drives the jaw pull rod 400 to move, thereby driving the rotating connecting block 501 to rotate. Since the operating jaws 502 are mounted on the rotating connecting block 501 and rotate synchronously with it, the operating angle of the operating jaws 502 can be adjusted, improving the convenience of operation. The driving assembly 300 can be located at the connecting sleeve 100. Under the linkage of the adjusting rod 600 and the jaw pull rod 400, the operator can adjust the angle of the operating jaws 502 at the connecting sleeve 100, making operation convenient and quick, and improving safety during operation. It is understood that the operating jaws 502 usually need to come into contact with wounds, and it is necessary to ensure the hygiene of the operating jaws 502. In this embodiment, adjusting the angle of the operating jaws 502 does not require contact with the jaws 502, maximizing safety. Since the angle can be adjusted without contact with the jaws 502, it can be adjusted in real-time during operation, ensuring smooth operation.

[0034] Optionally, in some embodiments of this invention, the rotating connecting block 501 and the operating jaw 502 are detachably connected via a connecting mechanism.

[0035] In this embodiment, the operating jaws 502 can be detachably connected to the rotating connecting block 501 using bolts, pins, snap-fits, or other methods. On one hand, the detachable design reduces manufacturing difficulty, thereby lowering production costs. On the other hand, different models of the operating jaws 502 can be replaced according to actual operational needs, improving the overall practicality of the device.

[0036] Optionally, in some embodiments of this example, the angle between the jaw assembly 500 after deflection and the extending direction of the mounting rod 200 is an adjustment angle, and the range of the adjustment angle is 0-60 degrees.

[0037] Please refer to Figure 4 As shown, in this embodiment, the jaw assembly 500 is driven to adjust its angle via the jaw lever 400. When the jaw assembly 500 swings too much, it will affect the driving effect of the jaw lever 400, causing it to fail to reset or fail to reach the predetermined support strength, thus affecting the usability of the jaw assembly 500. Therefore, in this embodiment, the adjustment angle of the jaw assembly 500 is 0-60 degrees, which can meet the operational requirements and ensure the stability of the entire jaw assembly 500.

[0038] Optionally, in some embodiments of this example, the hinge position between the mounting rod 200 and the jaw assembly 500 is the first hinge point, and the hinge position between the jaw pull rod 400 and the adjusting rod 600 is the second hinge point. When the adjustment angle of the jaw assembly 500 is 60 degrees, the distance between the first hinge point and the second hinge point is equal to the length of the jaw pull rod 400.

[0039] Please refer to Figure 3 As shown, in this embodiment, when adjusting the angle of the jaw assembly 500, the position of the second hinge point moves along the mounting rod 200, and the distance between the first hinge point and the second hinge point changes. When the adjustment angle of the jaw assembly 500 reaches 60 degrees, the distance between the first hinge point and the second hinge point is equal to the length of the jaw lever 400, making the jaw assembly 500, jaw lever 400, and mounting rod 200 form an isosceles triangle structure. At this time, the forces on the jaw lever 400 and the mounting rod 200 are more balanced, further improving stability.

[0040] Optionally, in some embodiments of this example, the mounting rod 200 is provided with a transverse limiting groove, and the adjusting rod 600 is slidably disposed in the transverse limiting groove.

[0041] In this embodiment, the mounting rod 200 has a transverse limiting groove along its length, and the adjusting rod 600 is slidably disposed in the transverse limiting groove. The transverse limiting groove is used to fix the adjusting rod 600 and prevent it from slipping out. At the same time, the transverse limiting groove also acts as a limit, ensuring that the adjusting rod 600 moves only along the transverse limiting groove, preventing the adjusting rod 600 from rotating or shaking, which would affect the angle adjustment effect of the jaw assembly 500 and improve the stability of the jaw assembly 500 during adjustment.

[0042] Optionally, in some embodiments of this example, the mounting rod 200 is provided with a travel limit component, which is used to limit the movement distance of the adjusting rod 600.

[0043] In this embodiment, the swing angle of the jaw assembly 500 is related to the moving distance of the adjusting rod 600. Therefore, to ensure that the swing angle of the jaw assembly 500 exceeds a preset value, a travel limit component is provided on the mounting rod 200. The travel limit component can be a limit block or a limit slot. When the adjusting rod 600 moves to its maximum position, the travel limit component acts as a limit, preventing the adjusting rod 600 from moving further, thereby ensuring the safety of the entire device.

[0044] Optionally, in some embodiments of this example, the rotating connecting block 501 is configured as an L-shaped structure.

[0045] Please refer to Figure 1 As shown, in this embodiment, the rotating connecting block 501 has an L-shaped structure, and two mounting parts are formed on both sides of the rotating connecting block 501, which are used to connect the mounting rod 200 and the operating jaw 502 respectively, thereby improving the stability during installation.

[0046] Optionally, in some embodiments of this example, the jaw assembly 500 is provided with an anti-slip component.

[0047] In this embodiment, the anti-slip component is an anti-slip protrusion or anti-slip stripe, which is used to increase the friction of the jaw assembly 500, ensure the clamping effect of the jaw assembly 500, and prevent slippage during operation.

[0049] This embodiment provides a surgical stapler, which includes: an operating handle 700 and a surgical jaw device provided in the above embodiment, wherein the connecting sleeve 100 of the surgical jaw device is rotatably connected to the operating handle 700.

[0050] Please refer to Figure 5As shown, in this embodiment, the operating handle 700 is rotatably connected to the connecting sleeve 100 of the surgical jaw device. The connecting sleeve 100 can rotate along the axis of the mounting rod 200, thereby rotating the entire surgical jaw device. The surgical stapler provided in this embodiment uses the above-mentioned surgical jaw device. The jaw assembly 500 is oscillated by the jaw pull rod 400 to achieve angle adjustment. The jaw assembly 500, the jaw pull rod 400, and the mounting rod 200 form a triangular support structure, which has high support strength and good stability.

[0051] In summary, this utility model provides a surgical jaw device, comprising: a connecting sleeve 100, a mounting rod 200, an adjusting rod 600, a driving assembly 300, a jaw pull rod 400, and a jaw assembly 500. The jaw assembly 500 is rotatably mounted on one end of the mounting rod 200, and the other end of the mounting rod 200 is connected to the connecting sleeve 100. One end of the jaw pull rod 400 is hinged to the jaw assembly 500, and the other end of the jaw pull rod 400 is hinged to the adjusting rod 600. The end of the adjusting rod 600 away from the jaw pull rod 400 is driven to cooperate with the driving assembly 300. The driving assembly 300 is used to drive the adjusting rod 600 to move along the length direction, and drives the jaw assembly 500 to deflect via the jaw pull rod 400. During the adjustment of the angle of the jaw assembly 500, the jaw assembly 500, the jaw pull rod 400, and the mounting rod 200 form a triangular support structure. The rotation connecting block 501 and the jaw lever 400 improve the stability of the jaw assembly 500 during use, preventing shaking or deflection during operation.
