Rapid blood vessel blocking device for free flap transplantation operation and use method of rapid blood vessel blocking device

Abstract

The invention relates to a rapid blood vessel blocking device for free flap transplantation operation. The rapid blood vessel blocking device comprises a blood vessel clamp, a blood vessel clamp sheath and a blood vessel clamp closing handle. The tail end is a circular ring, the center is in a trapezoidal bent shape sunken in the same direction, and the tip is provided with a fastener structure; a vascular clamp catch is fixed at the open end of the vascular clamp sheath and hinged with a vascular clamp button, and a vascular clamp push piece is arranged in the vascular clamp sheath; the vascular clamp rings are inwards placed on the vascular clamp sheath, and the vascular clamp closing handle is assembled on the side wall of the vascular clamp sheath; the vascular clamp closing handle comprises a connecting rod, a pressing rod and a closing rod; the connecting rod includes two symmetrical rectangular sheets, and the pressing rod is n-shaped and is erected on the vascular clamping sheath; the closing rod includes two rectangular pieces, one end of the closing rod is fixedly connected with the head end of the connecting rod, the other end of the closing rod obliquely extends to the upper side edge of the vascular clamp pressing piece, the two rectangular pieces are connected through a small cylinder, and the inclination direction of the closing rod is opposite to the connecting rod. The rapid blood vessel blocking device is used for rapidly blocking blood vessels in a flap transplantation operation, the blood vessels are conveniently cut off by an electric hook, and the operation time is shortened.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for rapidly blocking blood vessels in free skin flap transplantation and a method for using the same. Background technique [0002] A skin flap broadly refers to a living tissue mass with its own blood supply that contains skin tissue, and can be divided into pedicled flaps and free flaps. A pedicled flap means that during the formation and transfer of the flap, a part must be connected to the main body (flap donor area). This connected part is called the pedicle to maintain the blood supply of the flap. After being transferred to cover the wound (recipient area of ​​the flap), the blood supply of the pedicle still supplies nutrition in the early stage, and blood vessels around the wound surface of the flap recipient area grow into the flap in the late stage to strengthen the blood supply of the flap. [0003] The free flap is an axial flap, which means that the donor are...

Problems solved by technology

[0005] Manual ligation of a large number of branch vessels of the axial cardiovascular system during free flap transplantation takes a long time and is inconvenient to operate
