Tubular tissue suture device

Abstract

The invention relates to a tubular tissue suture device. The tubular tissue suture device includes a syringe needle, a catheter, an operating tube and a guide needle, wherein the syringe needle, the catheter and the operating tube are successively connected from front to back; the syringe needle is helical and hooked, and a hook body of the syringe needle can wind tubular tissue which need to be sutured for at least one circumference; the front part of the syringe needle is provided with a guide needle accommodating cavity; the catheter is provided with a guide needle outlet corresponding to the position of the guide needle accommodating cavity; one end of the guide needle is arranged in the operating tube, and is connected with a guide needle pushing mechanism which is also arranged in the operating tube; the other end of the guide needle is arranged in the catheter, the end part of the guide needle is provided with a detachable connection part, and the connection part is connected with a suture line; and the binding force between the guide needle and the connection part is less than that between the guide needle accommodating cavity and the connection part. The tubular tissue suture device is simple in structure, convenient to make and wide in application range; and meanwhile, compared with conventional equipment and means, the tubular tissue suture device has less surgical trauma, convenient implementation, less pain of patients, less possibility of error and less surgical risk.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tubular tissue suturing device. Background technique [0002] In the current operation, the procedure for ligation of human tubular tissues (such as great saphenous vein, fallopian tubes, vas deferens, etc.) is usually as follows: cut open the human tissue first, then clip out the tubular tissues that need to be ligated, and use sutures or ligature rings to close them. Ligation, and then put the sutured tissue back into the human body, and suture the wound of the human body; this step is not only cumbersome to operate, requires high requirements, and the ligation is not firm, but also has a large surgical trauma, which increases the pain of the patient; at the same time, because each patient is fat and thin Not all, the depth of incision tissue also varies from person to person, which increases the uncertainty of the operation and also increases the risk of the operation.
