Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to an adjustable multi-angle swing clamp applicator. Background Technology

[0002] Hemostasis is a crucial aspect of many surgical procedures, playing a vital role in minimizing blood loss, maintaining a clear surgical field, preventing damage to important tissues, ensuring surgical safety, and promoting postoperative wound healing. Existing hemostasis techniques include compression, ligation, electrocoagulation, suturing, and medication. In surgery, the use of ligation clips, also known as hemostatic clips / closure clips, to ligate blood vessels and thus block blood flow is a common and practical method, allowing for rapid and accurate hemostasis of visible bleeding points.

[0003] While traditional single-operation clip applicators have undergone many structural improvements, their single-operation nature inevitably leads to the following drawbacks: Firstly, when multiple blood vessels need to be stopped simultaneously, multiple operations are required, inevitably prolonging the surgical time. Since every second counts in surgery, current medical devices prioritize saving surgeons' time. Longer procedures increase surgeon fatigue and have a greater impact on the patient's health. Secondly, frequent insertion and removal of the clip significantly increases surgical risks and the probability of infection. Furthermore, during hemostasis, surgeons often encounter the problem of multiple bleeding vessels. Often, when inserting the clip a second time, the original vessels become blurred due to bleeding, making them difficult to locate. Sometimes, further cleaning is needed to find the vessels requiring hemostasis, which is more time-consuming. This can also lead to excessive bleeding for the patient, causing exhaustion and hindering recovery. Therefore, the use of pre-loaded multi-clip applicators with multiple ligation clips in surgical procedures has increased dramatically.

[0004] Traditional clamp-on clamp applicators, while capable of rotating 360° along the axial direction of the cannula to achieve clamping and release functions, have a fixed clamping angle and a fixed ligation clip model for each applicator. In actual use, such as during surgery, it is impossible to adjust the swing angle of the clamp perpendicular to the axial direction of the cannula according to actual needs, which is not conducive to practical use. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable multi-angle swing clamp applicator that can swing the clamp head, thereby improving the flexibility of the operation.

[0006] The present invention is achieved through the following technical solution: an adjustable multi-angle swing clamp applicator, the main body of which is the applicator, characterized in that: the applicator includes a handle 5, a connecting tube 2 and a magazine assembly 1, the connecting tube 2 is rotatably connected to the front end of the handle 5, the front end of the magazine assembly 1 is provided with a clamp head 8, and the clamp head 8 is linked with the firing handle 23 of the handle 5 through a push rod 21 to control the closing of the clamp head 8;

[0007] The magazine assembly 1 is further divided into a sleeve assembly 7 and an adjusting tube 22. The sleeve assembly 7 and the adjusting tube 22 are hinged to each other, so that the sleeve assembly 7 can swing according to the hinge point.

[0008] The regulating pipe 22 is also provided with a connector that extends backward through the connecting pipe 2. The front end of the connector is hinged to the sleeve assembly 7, so that the forward and backward movement of the connector can drive the sleeve assembly 7 to swing.

[0009] The push rod 21 is an elastic structure that can be bent and deformed at one end in the section between the sleeve assembly 7 and the adjusting tube 22. A reset structure is provided in the adjusting tube 22 to make the elastic structure return to a straight position.

[0010] Compared with previous technologies, the beneficial effects of the present invention are as follows:

[0011] 1. Here, the connecting tube 2 and the magazine assembly 1 are made into a hinged structure. Subsequently, the magazine assembly, i.e. the forceps head, is driven by the connecting parts to swing, which improves the flexibility of the operation.

[0012] 2. One section of the push rod 21 is designed as an elastic structure that can bend and deform, ensuring that the closure of the clamp head is not affected when the sleeve assembly 7 swings.

[0013] 3. The connecting tube 2 and the magazine assembly 1 are detachable and reassembled for easy replacement of the pliers head. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings:

[0025] In the description of this invention, it should be understood that the terms "front" and "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention 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, and therefore should not be construed as a limitation of this invention.

[0026] like Figure 1-9 As shown: An adjustable multi-angle swing clamp applicator, the main body of which is the applicator, the applicator includes a handle 5, a connecting tube 2 and a magazine assembly 1. The connecting tube 2 is rotatably connected to the front end of the handle 5. The front end of the magazine assembly 1 is provided with a clamp head 8. The clamp head 8 is linked with the firing handle 23 of the handle 5 through a push rod 21 to control the closing of the clamp head 8.

[0027] The magazine assembly 1 is further divided into a sleeve assembly 7 and an adjusting tube 22. The sleeve assembly 7 and the adjusting tube 22 are hinged to each other, so that the sleeve assembly 7 can swing according to the hinge point.

[0028] The regulating pipe 22 is also provided with a connector that extends backward through the connecting pipe 2. The front end of the connector is hinged to the sleeve assembly 7, so that the forward and backward movement of the connector can drive the sleeve assembly 7 to swing.

[0029] The push rod 21 is an elastic structure that can be bent and deformed at one end in the section between the sleeve assembly 7 and the adjusting tube 22. A reset structure is provided in the adjusting tube 22 to make the elastic structure return to a straight position.

[0030] Here, the forward and backward movement of the connector drives the oscillation of the sleeve assembly 7, with an oscillation amplitude of ±60°. The closing of the clamp head 8 in the clamp applicator via the push rod 21 is existing technology; the specific principle will not be elaborated here. The key point is that, due to the angular change between the sleeve assembly 7 and the adjusting tube 22, if the push rod 21 were a rigid rod, the angular change between the sleeve assembly 7 and the adjusting tube 22 would be impossible. Therefore, the push rod 21 in this area is replaced with a flexible structure capable of bending and deformation. This ensures that while maintaining the angular change between the sleeve assembly 7 and the adjusting tube 22, the push rod 21 can still trigger the opening and closing of the clamp head.

[0031] The sleeve assembly 7 has a fixed seat 12 at its rear end and a connecting piece 10 at its front end. The connecting piece 10 and the fixed seat 12 are hinged together by a first fixing pin 6.

[0032] The elastic structure is a pull rod spring 16 disposed in the adjusting tube 22, and the pull rod spring 16 is composed of several overlapping metal sheets;

[0033] The front end of the pull rod spring 16 extends into the sleeve assembly 7 and the front end of the pull rod spring 16 is connected to the push block 19, so that the sleeve 9 in the sleeve assembly 7 is pushed forward by the push block 19 to close the pliers 8.

[0034] The rear end of the pull rod spring 16 is provided with a connecting block 20, which is used to connect with the push rod 21 inside the connecting tube 2;

[0035] The reset structure consists of a first reset spring 14 and a second reset spring 15 located inside the adjusting tube 22 and closely attached to both sides of the pull rod spring 16.

[0036] Here, the first reset spring 14 and the second reset spring 15 are used to reset the pull rod spring 16. That is, the part of the pull rod spring 16 located in front of the first reset spring 14 and the second reset spring 15 can be bent. The bent pull rod spring 16 will be pulled through the first reset spring 14 and the second reset spring 15 and returned to a flat state by the clamping of the two.

[0037] As the lever spring 16 moves forward, the push block 19 moves forward to complete the automatic clamping on the magazine assembly 1. Continuing to press the firing handle 23 pushes the push block 19 forward, causing the sleeve 9 to move forward and complete the closing and clamping action of the jaws 8. Once the clamping is complete, releasing the firing handle causes the push rod 21 to reset and move backward, causing the push block 19 to move backward. The sleeve 9 also moves backward under the restoring force of the jaws 8, and the magazine assembly 1 resets, completing the opening action of the jaws 8.

[0038] Multiple ligature clips are pre-installed in the magazine assembly 1. Repeating the above actions enables continuous clamping and locking of the product.

[0039] The connector includes a push-pull rod 13 and a push-pull connecting rod 17 connected to each other. The push-pull rod 13 is installed inside the adjusting tube 22 and can slide back and forth within the adjusting tube 22. The front end of the push-pull rod 13 is hinged to the fixing seat 12 via a second fixing pin 11. The push-pull connecting rod 17 is located inside the connecting tube 2, and a rotating member 3 is rotatably provided at the rear of the connecting tube 2. The rotating member 3 and the push-pull connecting rod 17 are geared, so that when the rotating member 3 is rotated, the push-pull connecting rod 17 can move back and forth. (Instruction manual required) Figure 5 , 6 There are two second fixing pins 11. Only the lower second fixing pin 11 is used to realize the structure of the push-pull rod 13 and the fixing seat 12 being hinged to each other, while the upper second fixing pin 11 is simply used for fixing.

[0040] The rotating component here is subsequently mounted on the rotating sleeve 3. Alternatively, a mounting base can be added to the connecting pipe 2 to mount the rotating sleeve 3. Since the rotating sleeve 3 and the push-pull connecting rod 17 are geared, when the rotating sleeve 3 is rotated, the push-pull connecting rod 17 can be driven to move back and forth.

[0041] A rotating sleeve 3 is located on the rear outer wall of the connecting tube 2. The rotating sleeve 3 is fitted onto the front end of the handle 5, so that the rotation of the rotating sleeve 3 can drive the rotation of the connecting tube 2. Specifically, the annular rib with protrusions on the rotating sleeve 3 is in movable engagement with the annular rib on the handle 5. When the rotating sleeve 3 is rotated 360° along the axial direction of the device body, it can drive the entire magazine assembly and the connecting tube to rotate 360° axially.

[0042] The connecting pipe 2 and the magazine assembly 1 are detachable and detachable. The rear end of the adjusting pipe 22 of the magazine assembly 1 is provided with a connector, and the front end of the connecting pipe 2 is provided with a connecting sleeve corresponding to the connector. Since the two are detachable and detachable, the push-pull rod 13 and the push-pull connecting rod 17 are also detachable and detachable. Here, a horizontal limiting groove is provided at the front end of the push-pull connecting rod 17, and a protrusion is provided at the rear end of the push-pull rod 13. The two are connected by rotating the protrusion into the limiting groove.

[0043] This invention can be used as a clip-on rapid-fire applicator. Compared with the traditional clip-on rapid-fire applicator, its rapid-fire structure is installed in the magazine assembly 1. The principle and structure of the rapid-fire structure are existing technologies, so this invention will not elaborate further.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
