Description

Technical Field

[0001] This utility model belongs to the field of medical tool technology, specifically relating to disposable endoscopic assisted suturing and traction metal clips. Background Technology

[0002] Titanium clips are minimally invasive endoscopic surgical tools, mainly used for clamping intracavitary tissues during endoscopic ESD procedures. They are suitable for clamping ESD excision wounds and suturing perforated sites. Made of pure titanium wire or titanium alloy wire, each clip consists of at least a V-shaped clip body with transverse grooves on the inner side of the clamping section. The clip body is generally used to clamp and fix intracavitary tissues and is a commonly used medical tool.

[0003] The best way to prevent perforation is endoscopic wound suturing. Once perforation occurs, early endoscopic suturing can also avoid surgical treatment for the patient. Currently, the most commonly used tool for clamping wounds is metal clips. However, there are some problems in actual use. Specifically, when suturing and clamping large wounds, existing metal clips cannot stably clamp large wounds. The expansion range of the metal clip itself is limited by the length of the clip arm, which affects the clamping effect of the metal clip itself. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A disposable endoscopic-assisted suturing and traction metal clip includes a titanium clip releaser, a titanium clip body, and a clamping component. The titanium clip releaser is fitted with the titanium clip body at one end, and the titanium clip body is fitted with a clamping component for wound closure at one end. A connecting mechanism is fitted on the side of the clamping component to assist conventional titanium clips in clamping large wounds. The connecting mechanism includes a mounting side plate and a connecting collar. The mounting side plate is mounted on the side of the clamping component, and the connecting collar is mounted on the side of the mounting side plate.

[0007] As a preferred technical solution of this utility model, the connecting collar is made of a flexible, non-elastic ring, and the connecting collar itself remains open and ring-shaped after being subjected to external pressure, and the overall inner diameter of the connecting collar is larger than the clamp width of a conventional titanium clamp.

[0008] As a preferred technical solution of this utility model, the mounting side plate is composed of a rectangular fixing plate and a connecting arc plate. The clamping member has a mating groove inside, the rectangular fixing plate is installed in the mating groove, the connecting arc plate is installed on the side of the rectangular fixing plate, and the connecting arc plate is connected to the side of the connecting collar.

[0009] As a preferred embodiment of the present invention, the connecting mechanism further includes a clamping part, which is installed on the outer side of the connecting collar.

[0010] As a preferred technical solution of this utility model, the clamping member includes a clamping arm, a rotating end and a clamping seat. The clamping seat is installed at the end of the titanium clamp body, the rotating end is symmetrically rotated and installed in the clamping seat, and the clamping arm is installed on the side of the rotating end.

[0011] As a preferred embodiment of this utility model, the clamping arm and the rotating end are provided in two sets, and one set of the rotating end is connected to the connecting mechanism.

[0012] As a preferred embodiment of this utility model, the titanium clip releaser and the titanium clip body can be separated after the clamping component has closed the wound.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, by setting up a clamping component and a connecting mechanism, the clamping component clamps one side of the wound. Then, another set of conventional titanium clips is passed through the connecting collar. Pulling the conventional titanium clips pulls one side of the wound towards the other side, reducing the distance between the wounds. Then, the conventional titanium clips clamp the other side of the wound, completing the clamping closure of a large-area wound. This facilitates subsequent stable suturing and clamping operations, solving the problem of difficult suturing of large wounds and simplifying the suturing of such wounds. Compared with existing technologies, it reduces the technical difficulty, is easier to master and popularize, and the technical cost is easier to control, resulting in a high cost-performance ratio.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Depend on Figure 1 and Figure 2 As shown, it is a schematic diagram of the structure of the metal clip in this embodiment, including a titanium clip releaser 1, a titanium clip body 2 and a clamping member 3. The titanium clip releaser 1 is equipped with the titanium clip body 2 at one end, and the titanium clip body 2 is equipped with a clamping member 3 for clamping the wound at one end. The clamping member 3 is equipped with a connecting mechanism 4 on its side to assist conventional titanium clips in clamping large wounds.

[0026] When it is necessary to clamp a large area of ​​wound during use, the entire device is moved to the target position. Then, the operation of the titanium clip main body 2 and the titanium clip releaser 1 causes the clamping part 3 to clamp one side of the wound. After that, the second set of conventional titanium clips is moved to the target position, and one set of clamping arms of the conventional titanium clips is passed through the connecting mechanism 4. Then, the conventional titanium clips are pulled, causing the conventional titanium clips to move the device synchronously. This allows one side of the large area of ​​wound to move closer to the other side of the wound under the action of the conventional titanium clips. Then, the opening and closing of the conventional titanium clips is used to clamp the other side of the wound. In this way, the device clamps one side of the wound, the conventional titanium clips clamp the other side of the wound, and the connecting mechanism 4 work together to conduct and connect the wound, thus completing the clamping of the large area of ​​wound.

[0027] From the appendix Figure 3 As shown, it is a structural schematic diagram of the connecting mechanism 4 in this embodiment. The connecting mechanism 4 includes a mounting side plate 41 and a connecting collar 42. The mounting side plate 41 is mounted on the side of the clamping member 3, and the connecting collar 42 is mounted on the side of the mounting side plate 41.

[0028] In use, the conventional titanium clip is passed through the connecting collar 42, and then the conventional titanium clip is pulled. Driven by the connecting collar 42 and the mounting side plate 41, the clamping member 3 clamping one side of the wound moves to the other side of the wound. Then, in conjunction with the conventional titanium clip, the clamping of a large area of ​​wound is completed.

[0029] From the appendix Figure 4 As shown, the connecting collar 42 is a flexible, non-elastic ring. Even after being subjected to external pressure, the connecting collar 42 remains an open ring. Furthermore, the overall inner diameter of the connecting collar 42 is larger than the clamp width of a conventional titanium clamp.

[0030] In actual use, this device needs to move along the digestive tract lumen. The connecting collar 42 has a certain degree of flexibility, allowing it to pass through the endoscopic biopsy channel with the device. After the connecting collar 42 enters the digestive tract lumen through the biopsy channel, it remains open and ring-shaped due to its own characteristics, facilitating the subsequent connection and insertion of the titanium clip arms. Finally, considering the limitation of the overall inner diameter of the connecting collar 42, while ensuring that the traditional titanium clip arms can be inserted into the connecting collar 42, the diameter of the connecting collar 42 is minimized as much as possible to shorten the distance between the two wound surfaces after closing, facilitating subsequent clamping and suturing.

[0031] From the appendix Figure 4 As shown, the mounting side plate 41 is composed of a rectangular fixing plate and a connecting arc plate. The clamping member 3 has a mating groove inside. The rectangular fixing plate is installed in the mating groove, and the connecting arc plate is installed on the side of the rectangular fixing plate. The connecting arc plate is connected to the side of the connecting collar 42.

[0032] During use, the rectangular fixing plate is used to install the connecting mechanism 4 on the side of the clamping part 3. The shape of the rectangular fixing plate itself limits the position of the connecting mechanism 4, preventing the connecting mechanism 4 from being misaligned or deflected when the equipment passes through the digestive tract, which would affect the subsequent docking of conventional titanium clamps.

[0033] From the appendix Figure 4As shown, it is a structural schematic diagram of the connecting mechanism 4 in this embodiment. The connecting mechanism 4 also includes a clamping part 43, which is installed on the outside of the connecting collar 42. During use, the conventional titanium clamp arm contacts the clamping part 43, which enhances the stability of the connecting collar 42 itself. When the conventional titanium clamp pulls the device as a whole to move, the clamping part 43 can withstand a large amount of pulling force.

[0034] From the appendix Figure 5 As shown, it is a structural schematic diagram of the clamping member 3 in this embodiment. The clamping member 3 includes a clamping arm 31, a rotating end 32 and a clamping seat 33. The clamping seat 33 is installed at the end of the titanium clamping body 2. The rotating end 32 is symmetrically rotated and installed in the clamping seat 33. The clamping arm 31 is installed on the side of the rotating end 32.

[0035] During use, the titanium clamp body 2 and the clamping seat 33 cooperate to drive the rotating end 32 to rotate inside the clamping seat 33, thereby controlling the position, angle and spacing of the two sets of clamping arms 31, so that the clamping arms 31 clamp one side of the wound.

[0036] From the appendix Figure 2 As shown, the titanium clip releaser 1 and the titanium clip body 2 can be separated after the clamping member 3 completes the wound clamping. During use, after the device completes the wound clamping, the separation of the titanium clip releaser 1 and the titanium clip body 2 leaves the titanium clip body 2, clamping member 3 and connecting mechanism 4 inside the patient's body, which facilitates subsequent stable clamping of the wound. After the wound heals, the titanium clip body 2, clamping member 3 and connecting mechanism 4 will fall off from the healed cavity wall and be expelled from the body along with food and other substances.

[0037] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
