Retraction type laparoscope puncture device

Abstract

The invention relates to a medical puncture device, in particular to a retraction type laparoscope puncture device capable of preventing an abdominal cavity or thoracic cavity visceral organ and a muscular tissue from being damaged. The puncture device comprises a sheath body (8) of which the cross section is circular and a core rod (9), wherein a cylindrical cavity (12) is formed close to the rear end of the sheath body (8). The puncture device is characterized in that: a core rod positioning mechanism (3) is arranged on one side of the cavity (12); a circular clamping hole groove (20) is formed at the rear end of the core rod (9); the clamping hole groove (20) is matched with a clamping rod (6) at the tail end of the core rod positioning mechanism; the tail end of the core rod (9) is horizontally connected with a second spring piece (11); the other end of the second spring piece (11) is horizontally and fixedly connected to a connecting seat (15); a T-shaped push rod (1) is matched with the connecting seat (15); and the connecting seat (5) is positioned between the push seat of the T-shaped push rod (1) and the cylindrical cavity (12). Due to the adoption of the technical scheme, the puncture device can completely prevent the abdominal cavity or thoracic cavity visceral organ and the muscular tissue from being damaged for a second time.

Description

technical field [0001] The invention relates to a medical puncture device, in particular to a retractable laparoscopic puncture device capable of avoiding damage to abdominal cavity or thoracic viscera and muscle tissue. Background technique [0002] The puncture device has been used as an auxiliary doctor to perform thoracic or intra-abdominal surgery, but the puncture device of the prior art has the following defects: [0003] First, during the whole operation process, the puncture device has been exposed in the abdominal cavity or thoracic cavity, which may cause damage to the viscera of the abdominal cavity or thoracic cavity; [0004] Second, there is a blade design in the middle of the puncture device of the prior art, and its sharpness makes the muscle fracture damage of abdominal wall or chest wall larger. [0005] In summary, it can be seen that the puncture device of the prior art cannot avoid secondary injury to the patient. Contents of the invention [0006] ...
