Embodiment Construction

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0024] Such as figure 1 As shown, the micro-instrument set used for intraoperative vascular anastomosis includes surgical operation scissors 1 and a blood vessel bifurcation angle measuring device 2 matched with the surgical operation scissors 1; the surgical operation scissors 1 includes a handle 10 and hinged on Hold the fixed cutting edge 11 and the adjustable cutting edge 12 on the handle 10. The adjustable cutting edge 12 includes a fixed part 120 hinged on the handle 10 and a cutting edge part 121 detachably connected to the fixed part 120. A cutting edge 122 is embedded in the cutting edge 11 and the cutting edge portion 121 of the adjustable cutting edge 12 .

[0025] The hinged way is to form a hinged stru...

Abstract

The invention discloses a microscopic instrument suite for intraoperative vascular anastomosis. The microscopic instrument suite comprises a pair of surgical operation scissors and a vascular bifurcation angle measurer matching the surgical operation scissors. The surgical operation scissors comprise a holding handle, a fixed scissor blade and an adjustable scissor blade, wherein the fixed scissorblade and the adjustable scissor blade are hinged to the holding handle respectively; the adjustable scissor blade comprises a fixed part hinged to the holding handle and a scissor blade part detachably connected to the fixed part, and blades are embedded in the fixed scissor blade and the scissor blade part of the adjustable scissor blade. On the basis of the special shear blade structure of thesurgical operating scissors, the angle or length of the shear blades can be adjusted or replaced according to different blood vessel bifurcation angles, blood vessels can be trimmed conveniently, thesurgical effect is improved, and the requirement for trimming blood vessel bifurcations of different lengths is met; the blood vessel bifurcation angle is reliably measured through the blood vessel bifurcation measurer, so that a reliable and accurate basis is provided for blood vessel trimming operation of the surgical operation scissors, and accurate trimming of blood vessels is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a microinstrument set for intraoperative blood vessel anastomosis. Background technique [0002] At present, free skin flap transplantation has become a routine technique for repair and reconstruction after radical surgery for malignant tumors. Compared with traditional techniques, free flaps can better restore the shape and function of the maxillofacial region. The key technique for free flap transplantation is to perform vascular anastomosis using microsurgical techniques. If the vascular intima is damaged or the anastomosis fails during the operation, the free flap transplantation will also fail, causing huge physical, psychological and economic burdens to the patient. [0003] There are many difficulties in intraoperative vascular anastomosis, and the mismatch between the diameter of the donor vessel and the recipient vessel is one of the key factors affecting t...
