A kind of tissue forceps for thyroid surgery

technical field

The utility model relates to the field of medical surgical instruments, in particular to a tissue forceps for thyroid surgery.

Background technique

In recent years, the incidence of thyroid tumors in my country has been increasing year by year, and the amount of thyroid surgery has also increased rapidly. At the same time, with the advancement of medicine, the clinical requirements for the quality of thyroid surgery are getting higher and higher, including smaller surgical incisions and less tissue damage. On the other hand, clinical thyroid surgery has more and more serious postoperative complications, including postoperative bleeding and compression of blood vessels, injury of recurrent laryngeal nerve or superior laryngeal nerve, etc. The main reasons for these complications are the narrow surgical field and the variation of the anatomical structure position. Even experienced doctors cannot avoid the occurrence of surgical complications. Therefore, surgical instruments more suitable for the development of specialties are needed to improve the operation quality of the operation, improve the level of medical technology, and reduce the complications caused by the operation.

Tissue forceps are a medical surgical instrument often used in surgical operations. They are often used to clamp and fix the target diseased tissue to be exposed in the surgical field, so as to facilitate the surgeon to cut the diseased tissue. At present, in clinical thyroid surgery, most of the thyroid tissues need to be clamped with tissue clamps, especially when separating and cutting the upper thyroid pole, it is often necessary to use tissue clamps to clamp the upper thyroid pole to fully expose the upper thyroid pole and surrounding tissues To avoid postoperative hoarseness caused by injury to the superior laryngeal nerve when the upper pole of the thyroid is removed.

There are only one type of traditional tissue forceps routinely used in clinical practice, and when the tissue forceps grips thyroid tissue, it is easy to cause tissue avulsion; or because the tissue forceps are not firmly fixed, the clamped tissue slips from the forceps head, thereby increasing the human body. The degree of anatomical tissue damage and the amount of surgical blood loss affect the smooth operation of the operation. Most of these surgical forceps are straight rods, and the surgeon is not easy to use force during the operation, which affects the work efficiency and increases the difficulty of the operation. On the other hand, the forceps heads of the traditional straight-bar tissue forceps are all flat rat rake teeth. When the forceps head is used for surgical operation, the grasping target is often not clear enough, and the target tissue cannot be directly grasped; secondly, the grasping force If it is not enough, the fixation is not firm, and the tissue is easily slipped from the forceps head or the tissue is torn.

Therefore, there is an urgent need in the field to develop a new type of surgical tissue forceps that is suitable for thyroid surgery and is easy to clamp. It is mainly aimed at thyroid surgery, and can more accurately reveal the surgical field of view of the upper pole of the thyroid in a narrow operating range, which is convenient for surgery. The doctor ligates the superior thyroid artery to avoid accidentally cutting the external branch of the superior laryngeal nerve during the operation.
