Laparoscope and common bile duct exploration T tube introducer

Abstract

The invention relates to a laparoscope and common bile duct exploration T tube introducer, which comprises a holding handle (1), a T tube control external sleeve (2), a T tube staff gauge (12) arranged at an introducing end, an inner half-tube-shaped support frame (3), a sliding sealing groove (4) at the side wall of the external sleeve, a T tube positioning support frame (10) and a sliding air-tight seal pad (11), wherein a T tube locking and unlocking clamp (5) and a T tube locking and unlocking key (6) are arranged on the inner half-tube-shaped support frame (3), a T tube release elastic key (7) controls and is connected with a release connecting rod (8), a T tube release spring (9) is positioned at the tail end of the release connecting rod (8), a T tube abdomen external drainage end is positioned and locked in the T tube locking and unlocking key (6), a T tube introducing drainage (in a common bile duct) section is positioned in the T tube positioning support frame (10), and the inner half-tube-shaped support frame (3) is locked and stored in the T tube control external sleeve (2). The T tube orientation and detection are completed in one step, a T tube is unlocked, released and introduced for drainage in real time, the operation time is shortened, and the pain of a patient is reduced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a "T-tube" inserter for laparoscopy and common bile duct exploration. Background technique [0002] In the prior art, the "T-tube" is placed only directly with laparoscopic surgical forceps or with a double-tubular inserter, which often makes it difficult to place the "T-tube", and the "T-tube" falls off prematurely. Difficulty in post-release or prolapse after insertion, prolonging the operation time, or changing the surgical method during the operation to enlarge the incision, bringing pain and injury to the patient. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a "T-tube" inserter for laparoscopy and common bile duct exploration; a "T-tube" inserter for laparoscopy and common bile duct exploration, which uses a grip and "T-tube" to control the overtube, There is a "T tube" scale at the insertion end, and a ...
