Puncture Instrument Product Overview

The puncture instrument is a type of surgical tool primarily used in minimally invasive procedures (such as laparoscopic, thoracoscopic, arthroscopic, and other endoscopic surgeries). Its core function is to establish and maintain a surgical access pathway, facilitate the insertion of surgical instruments into the body cavity, and assist in the dissection of human tissues, thereby providing both visual and operational space for surgical procedures.

Based on differences in product design and usage scenarios, puncture devices can be classified into two categories: single-use puncture devices and reusable puncture devices; in current clinical practice, single-use sterile puncture devices are predominantly employed. Depending on their blade design, these devices can also be categorized into various types—such as puncture-type and cutting-type devices—to meet the operational requirements associated with different surgical sites and tissue thicknesses.

The puncture device typically consists of components such as a puncture needle, a cannula, a sealing assembly, and an air valve; some models are also equipped with auxiliary puncture positioning structures. The device must possess excellent sharpness, structural strength, and sealing performance to ensure stable intraoperative inflation pressure and smooth insertion and withdrawal of the instrument, thereby reducing the risk of surgical complications.

Absorbable sutures are a category of surgical suturing materials that are gradually degraded and absorbed within human tissues. They are primarily used for suturing and ligating soft tissues during surgical procedures, and are particularly suitable for suturing deep or subcutaneous tissues, as well as in scenarios where prolonged suture strength is not required. This approach eliminates the need for postoperative suture removal in patients and reduces the risk of infection associated with secondary surgical interventions.

Depending on their material composition, absorbable sutures are primarily classified into two categories: natural absorbable sutures and synthetic absorbable sutures. Natural absorbable sutures include materials such as catgut and collagen sutures; synthetic absorbable sutures encompass materials such as polylactic acid sutures, polylactic-co-hydroxyethylacrylic acid sutures, and polidioxanone sutures. The degradation and absorption timelines, as well as the duration of tensile strength retention, vary among these materials, enabling them to be tailored to the specific requirements of different surgical procedures.

Absorbable sutures must typically meet biocompatibility requirements, ensure that their degradation products are non-toxic, induce minimal tissue reaction during the absorption process, and maintain sufficient tensile strength during the critical wound healing phase to ensure optimal wound healing outcomes; they are currently widely used in surgical procedures across various clinical specialties, including general surgery, obstetrics and gynecology, orthopedics, and plastic surgery.
