Embodiment

[0019] figure 1 It is a schematic diagram of the structure of the tracheal stapler in the embodiment of the present invention. Such as figure 1 As shown, the tracheal stapler provided by this embodiment includes a plurality of staples 1 and a bending part 2. Specifically, a plurality of staples 1 are distributed in a circular array around the trachea 10, and each staple 1 extends from the outside to the inside. Puncture the trachea 10. The bending component 2 can be axially inserted into the trachea 10 to bend the staple legs 12 (such as image 3 Shown).

[0020] In this embodiment, the bending component 2 has a sleeve tube 21 and a ball head core rod 22; the ball head core rod 22 is composed of a ball head 221 and a rod body 222, the rod body 222 axially penetrates the sleeve 21, and the rod body 222 There is a clearance fit with the sleeve 21.

[0021] In this embodiment, in order to enable the bending component 2 to be smoothly inserted into the patient's trachea 10 and reduce...

Abstract

The invention discloses trachea anastomat.The trachea anastomat comprises multiple anastomotic nails and a bending part; the anastomotic nails are distributed around a trachea in an annular array mode, and each anastomotic nail punctures the trachea from outside to inside; the bending part can be inserted into the trachea in the axial direction and used for bending the nail legs, extending into an anastomotic tube, of the anastomotic nails.According to the trachea anastomat, the bending part is adopted to conveniently bend the nail legs, extending into the anastomotic tube, of the anastomotic nails inside the trachea, the operation difficulty of trachea anastomosis is greatly reduced, medical personnel can complete the trachea anastomosis easily, efficiently and conveniently, an anastomotic leakage risk is effectively prevented, and therefore the success rate of trachea sleeve-type anastomosis is increased.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a tracheal stapler. Background technique [0002] The growth of tumor tissue in the trachea can compress or block the trachea, which will cause the trachea to collapse or become narrow, causing difficulty in breathing, seriously affecting the quality of life of the patient, and even death from suffocation. In order to perform radical resection of the tumor, prevent tumor recurrence, eliminate tracheal obstruction and improve ventilation function, circular tracheal resection and sleeve anastomosis are usually adopted in clinical practice. In the tracheal sleeve anastomosis, the trachea at both ends of the trachea should be sutured intermittently from back to front with sutures. At present, the operation of tracheal sleeve anastomosis is difficult and the complication rate is high, so it is difficult to promote this type of operation in China. Summary of the invention [0003] ...
