This patent innovatively addresses the need for surgical wound exposure in thoracic surgery, achievingSingle-Hand Remote Control, Synchronous Retraction and Extension of Dual Retractors, Multi-Level Limit Fixation, addressing the pain points of traditional retractors, such as large space occupation, labor-intensive operation, and susceptibility to wound retraction. It offers clinical advantages of high efficiency, convenience, and stability, representing a practical medical device innovation well-suited to real-world operating room scenarios.

Thoracic SurgeryAs a core clinical specialty dedicated to the diagnosis and treatment of diseases affecting intrathoracic organs, it primarily focuses on the diagnostic evaluation and surgical management of benign and malignant conditions involving key structures such as the esophagus, lungs, and mediastinum. High-volume procedures routinely performed in thoracic surgery include cervical anastomosis for esophageal cancer and single-port laparoscopic surgery.

During the performance of such procedures,Apply stable and moderate traction to the surgical incision to achieve an adequate and clear operative field., is a key prerequisite for ensuring precise surgical manipulation, minimizing collateral tissue damage, and enhancing surgical safety and efficiency, an operation that relies heavily on basic medical devices such as surgical retractors.

In current clinical practice in China, the widely adopted approach remainsTraditional Stainless Steel Integrated Handheld Surgical Retractor,Such retractors feature a simple structure, fixed length, and an overall short design, leading to a series of unavoidable limitations and clinical pain points in practical use:

First,Limited Working Distance of Traditional Retractors, the assistant must operate manually in close proximity, with their arms and hands inevitably occupying the already constrained surgical field, which can easily cause spatial interference with the lead surgeon and the scrub nurse, thereby affecting the pace and fluidity of the procedure;

Secondly,Traditional retractors feature a unilateral retraction structure., to achieve symmetrical traction and expansion on both sides of the wound, two retractors must be used simultaneously with coordinated two-handed operation by an assistant; this approach is not only physically demanding and requires high operational coordination, but also makes it difficult to ensure uniform traction force and distance on both sides;

Third,Traditional retractors do not have a position-locking function., once retracted into position, the retraction state can only be maintained manually. Prolonged manipulation easily leads to fatigue-induced tremors, and the surrounding soft tissues tend to recoil due to elasticity, resulting in inadequate exposure of the surgical field and increasing the difficulty and risk of the procedure.

With the rapid development of surgery towards minimally invasive, refined, and efficient approaches, existing retractors are no longer able to meet the supporting requirements for high-quality thoracic surgeries, creating an urgent clinical need forA Novel Surgical Retractor Enabling Remote Operation, Bilateral Synchronous Retraction with Single-Hand Use by One Operator, Adjustable Retraction Range, and Stable Locking in the Expanded State, to address the design flaws of existing instruments and effectively enhance the quality of surgical coordination and clinical user experience.

Addressing the prominent issues associated with traditional surgical retractors in thoracic surgery clinical practice, such as excessive space occupation, labor-intensive operation, and unstable retraction, this patent leverages a novel structural layout and transmission mechanism to achieve functional upgrades and experiential innovation in surgical retraction instruments. It possesses multiple technological innovations and comprehensive advantages that significantly distinguish it from existing products.

In terms of operational mode, this device breaks the limitations of traditional close-range handheld use,Adopting a remote control structure that combines an "extended-length long shaft with an independent handle,"The operator can perform all retraction maneuvers from a position remote from the surgical incision, effectively preventing the hands and forearms from entering the core operative field and encroaching on the working space. This approach minimizes interference with the surgeon’s operational pathway and visual field at the source, making it particularly suitable for high-precision procedures in confined spaces, such as single-port laparoscopy and cervical anastomosis.

In terms of functional implementation,Innovatively adopts an integrated linkage system comprising a "handle sliding component, pull-cable transmission, internal slider within the long shaft, and return spring", a simple push-pull action at the handle drives the pull cord to move the hook at the front end of the long rod in a directed manner, forming bidirectional counter-traction with the fixedly set hook one, truly enabling single-person, single-hand synchronous retraction on both sides of the wound, significantly reducing operational complexity and physical exertion for medical staff, and enhancing the fluency and coordination of surgical assistance;

In terms of positioning stability，The device forms a multi-stage locking mechanism through the "multiple sets of evenly spaced limit blocks and secondary engageable limit block" at the slot of the handle., once retracted to the ideal wound width, it can be quickly locked and positioned, reliably maintaining the spacing between retractors and the wound retraction state. This prevents narrowing of the surgical field and inadequate exposure due to manual fatigue or tissue elastic recoil, significantly enhancing the safety and continuity of the surgical procedure;

On Structural Reliability, this patent employs a differentiated optimization design for the internal sliding components: the guide rail and slider within the handle adopt a circular structure to ensure smooth movement, while the guide rail and slider within the long rod adopt a square structure to restrict deflection and wobbling; meanwhile, Hook 1 and Hook 2 employ“Uniform specifications, symmetrical morphology”The standardized design ensures uniform force distribution and stable traction, while facilitating manufacturing, cleaning, and sterilization, thereby fully complying with clinical usage standards and safety requirements for medical devices.

Compared with traditional stainless steel handheld retractors, this patented technology inOperating Distance, Usage Efficiency, Locking Effect, Spatial Adaptabilityachieving comprehensive improvements in these areas, effectively meeting the development trends of minimally invasive, precise, and efficient practices in thoracic surgery, possessing outstanding clinical practical value and potential for large-scale promotion, and boasting broad prospects for practical application and market expansion in China’s surgical instrument market.
