Embodiment

[0019] figure 1 It is a schematic structural diagram of the tracheal anastomosis device provided in the embodiment of the present invention; figure 2 It is a structural diagram of the outer contour of the anastomotic tube in the embodiment of the present invention. Such as figure 1 and figure 2 As shown, the tracheal anastomosis device provided in this embodiment includes: an anastomosis tube 1 , several nail holders 2 , and a ball pusher 3 . Specifically, a plurality of nail holders 2 are distributed in an annular array around the axis of the anastomotic tube 1 inside the anastomotic tube 1, and the anastomotic tube 1 has a strip-shaped hole 11 at a position corresponding to each nail holder 2, and each nail holder An anastomotic staple 4 is placed in each of the 2.

[0020] In this embodiment, the bottom of each nail holder 2 is connected to the inner peripheral wall of the anastomotic tube 1 by a metal sheet 5 . The ball push rod 3 can move axially in the anastomotic...

Abstract

The invention discloses a tracheal anastomosis device. The tracheal anastomosis device comprises an anastomosis tube, a plurality of nail supporters and a bulb push rod, wherein the plurality of nail supporters are arranged in the anastomosis tube and distributed in a ring array around the axial line of the anastomosis tube, and the bottom of each nail supporter is connected to the inner peripheral wall of the anastomosis tube through a metal plate; the bulb push rod can move axially in the anastomosis tube; a strip-shape hole is formed at the position, corresponding to each nail supporter, of the anastomosis tube, and an anastomosis nail is placed in each nail supporter in a manner that the nail leg of the anastomosis nail faces the corresponding strip-shape hole. With the adoption of the tracheal anastomosis device, the operation difficulty of the sleeve tracheal anastomosis is greatly reduced, medical workers can easily and rapidly complete the tracheal anastomosis, meanwhile, the risk of anastomotic fistula can be effectively reduced, and further, the sleeve tracheal anastomosis can be conveniently popularized.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tracheal anastomosis device. Background technique [0002] The growth of tumor tissue in the trachea can compress or block the trachea, leading to collapse or stenosis of the trachea, causing difficulty in breathing, seriously affecting the quality of life of the patient, and even death by suffocation. In order to perform radical tumor resection, prevent tumor recurrence, eliminate tracheal obstruction, and improve ventilation function, circular tracheal resection and sleeve anastomosis are usually performed clinically. In the tracheal sleeve anastomosis, the trachea at both ends should be sutured intermittently from back to front with sutures. At present, tracheal sleeve anastomosis is difficult to operate and has a high incidence of complications, so it is difficult to fully promote this type of operation in China. Contents of the invention [0003] Aiming at ...
