Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically a laparoscopic free organ retractor. Background Technology
[0002] During laparoscopic procedures, when traction or exposure of surgical area tissues is inconvenient, a laparoscopic retractor is required. However, existing laparoscopic retractors cannot meet the needs. A search revealed a laparoscopic retractor disclosed in application number CN202123023239.5, which describes a device comprising a puncture tube, a hollow sealing ring on the outer surface of one end of the puncture tube, a blunt-tipped tube on the inner wall of the hollow sealing ring, a hollow blunt-tipped block on the outer surface of one end of the blunt-tipped tube, and a pull ring on the inner wall of the hollow blunt-tipped block. The device utilizes the puncture tube, hollow sealing ring, blunt-tipped tube, hollow blunt-tipped block, and pull ring for traction. The device, consisting of a rod, pull ring, and traction line, is used to puncture the puncture point through a puncture tube. Its simple operation avoids damage to the patient's internal organs. The conical shield, sliding ring, transparent shield, and contact ring protect the puncture wound and prevent secondary injury. However, in practical use, the device has the following drawbacks: it cannot perform multi-directional traction on target tissues within organs, and its operational flexibility and control precision are limited, failing to meet surgical requirements. Therefore, a more practical laparoscopic free organ traction device needs to be designed. Utility Model Content
