Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a ligation clip with a continuous-fire applicator. Background Technology

[0002] In minimally invasive surgical procedures such as laparoscopic surgery, efficient and reliable handling of blood vessels and tissue bundles is crucial. The clip ligator with continuous firing function is a key instrument that has emerged in this context. It can preload multiple ligation clips during the operation and fire them through continuous mechanical action, which significantly reduces the frequency of instrument changes and surgical interruption time, thereby improving the overall smoothness and efficiency of the operation. It is especially suitable for complex surgical scenarios that require rapid and multiple ligation.

[0003] Traditional repeating clip applicators have a significant drawback: they lack a visual means of managing the number of remaining clips during surgery. Doctors cannot intuitively understand the remaining amount of clips in the magazine during the operation and can only estimate it based on personal experience and feel. This uncertainty not only disrupts the continuity of the operation but also brings additional psychological pressure and operational burden to the surgeon.

[0004] This lack of visibility directly leads to many inconveniences and waste of resources in clinical use. In order to avoid running out of clips in critical surgical steps, doctors tend to replace instruments in advance or discard clip applicators that may still have clips. This conservative strategy results in a large waste of unused ligation clips. At the same time, frequent instrument replacements also increase surgical time and costs and may bring potential infection risks. Therefore, a device that can display the remaining amount of ligation clips in real time has a clear clinical need and improvement value. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a ligation clip with a rapid-fire applicator to solve the problem of waste caused by traditional rapid-fire applicators mentioned in the background art.

The instrument body serves as the core support structure of the entire device, providing a mounting base for other components and ensuring overall stability. The handle fixed to the lower end of the body facilitates the operator's grip and control. The anti-slip pad wraps around the outer ring of the handle to increase frictional resistance and prevent slippage. The adjustable wrench, located at the lower end of the handle, drives the internal mechanism to complete loading and firing preparation through its reciprocating motion. The outer tube, fixed to one side of the body, serves as a clip delivery channel and a protective shell.

[0009] Preferably, the visual component includes a rapid-fire sleeve, which is movably disposed inside the outer tube. The rapid-fire sleeve is made of transparent material. A clamp head is fixedly disposed at the end of the outer tube away from the instrument body. The visual component is integrated into the outer tube to provide observation function. The rapid-fire sleeve is movably disposed inside the outer tube to accommodate and sequentially push multiple ligation clips. Its transparent material allows direct viewing of the clip status. The clamp head is fixed at the distal end of the outer tube to guide the clips to close and compress the target tissue.

[0010] Preferably, the outer tube has a groove, and an adhesive layer is fixedly disposed around the outer ring of the groove. The groove is formed on the wall of the outer tube to create an observation window, and the adhesive layer surrounds the edge of the groove to fix the viewing strip.

[0011] Preferably, a visible strip is pasted on the outer layer of the adhesive layer. The visible strip is made of transparent material, and a scale is fixedly provided on the lower side of the slot. The visible strip is pasted on the adhesive layer, and its transparency allows the surgeon to intuitively see the number of remaining clips inside.

[0015] 1. This ligation clip with a rapid-fire applicator features an anti-slip pad on the outer ring of the handle, significantly enhancing grip stability and handling feel, effectively preventing slippage during surgery. The reciprocating motion design of the adjustable wrench makes loading and firing smooth and effortless, greatly simplifying surgical procedures and improving overall operational efficiency. At the same time, the transparent rapid-fire sleeve of the visual component and the transparent visual strip on the slot together form a clear and intuitive visual window, allowing the surgeon to directly observe the number of remaining clips in the internal clip compartment. Combined with the scale markings on the side, the surgeon can quickly calculate and plan subsequent operations, greatly enhancing the predictability and control during the surgical process.

[0016] 2. This ligation clip with a continuous-fire applicator, through its ingenious internal continuous-fire sleeve structure and the coordinated work of the pusher plate, enables the pre-loading and sequential automatic supply of multiple ligation clips, avoiding the cumbersome process of frequently changing single-shot instruments, significantly shortening the operation time. It is especially suitable for intensive operation scenarios that require rapid and continuous clipping. At the same time, the groove design of the clamp head can perfectly match the ligation clip, ensuring that the clip moves smoothly and gradually closes during the advancement process, ultimately firmly pressing and locking the target tissue, providing a stable and reliable ligation effect and ensuring the safety of the operation.

[0017] 3. This ligation clip with a continuous-fire applicator connects the main body of the instrument to the outer tube via a unique rotating head and screw. This connection method is robust and precise, ensuring the stability of the internal transmission components. At the same time, installation or separation can be quickly completed with a simple rotation operation. This design greatly facilitates postoperative cleaning, disinfection, and replacement and maintenance of parts, effectively extending the service life of the instrument and reducing long-term usage costs.

A groove 7 is formed on the outer tube 4, and an adhesive layer 8 is fixedly mounted on the outer ring of the groove 7. A transparent visual strip 9 is attached to the outer layer of the adhesive layer 8. A scale 10 is fixedly mounted on the lower side of the groove 7. The visual component is installed on the outer tube 4 for observing the internal state. The rapid-fire sleeve 5 is movably mounted... The outer tube 4 is used to accommodate multiple ligation clips and push them sequentially. Its transparent material allows direct observation of the clip status. The forceps head 6 is fixed to the far end of the outer tube 4 to guide and close the ligation clips. The slot 7 is opened on the wall of the outer tube 4 to form an observation window. The adhesive layer 8 is set on the outer ring of the slot 7 to fix the visual strip 9. The visual strip 9 is pasted on the adhesive layer 8. Its transparency allows the surgeon to intuitively see the number of clips inside. The scale 10 is set on the lower side of the slot 7 to provide a quantitative reference for easy calculation of the remaining clips.

[0026] A rotating head 11 is fixedly installed at the end of the outer tube 4 away from the clamp head 6. A screw 12 is fixedly installed at the end of the rotating head 11 away from the outer tube 4. A threaded hole 13 is opened at the end of the instrument body 1 near the rotating head 11.

[0027] Working principle: Before surgery, the operator securely inserts the magazine, pre-loaded with multiple ligation clips, into the instrument body 1. Then, by repeatedly turning the adjustable wrench 3, the internal transmission mechanism is activated, driving the automatic firing sleeve 5 to load the first ligation clip, smoothly pushing it to the forceps head 6 and keeping it ready for firing. During surgery, the operator manipulates the instrument body 1 by holding the handle 2, accurately positioning the target tissue to be ligated between the two clamping arms of the forceps head 6. Then, by firmly gripping the handle 2, the internal precision linkage mechanism activates, pushing the pusher plate forward, thereby steadily pushing the ligation clip, located in the automatic firing sleeve 5, into the groove at the front end of the forceps head 6 along the track. During this process, the two arms of the ligation clip are guided by the groove shape to gradually close and finally firmly press and lock the target tissue, thereby achieving reliable ligation. Throughout the operation, the doctor can observe the internal situation through the slot 7 opened on the outer tube 4. The adhesive layer 8 covering the outer ring of the slot 7 firmly attaches the transparent viewing strip 9. Through the viewing strip 9, the number of remaining ligation clips in the continuous firing sleeve 5 can be clearly seen. The scale 10 next to it further provides a quantitative reference, which is convenient for quickly calculating the remaining clips and planning subsequent operations. In addition, the rotating head 11 located at the end of the outer tube 4 can be manually rotated, driving the screw 12 at its front end to screw into or out of the threaded hole 13 at the end of the instrument body 1.
