Description
Technical Field
The invention relates to a uterine manipulator, in particular to a uterine manipulator with a rotatable uterine manipulator head and a cavity seal, belonging to the technical field of medical appliances.
Background
Uterine manipulator is an indispensable instrument for hysterectomy under laparoscopy, sub-hysterectomy and wide range of hysterectomy. When the hysterectomy is performed, the entire cervical part is required to be dissociated in a ring shape, and when the cervical part is dissociated, the existing uterine lifting head cannot rotate, so that in order to expose the cervical part of an operation part, an auxiliary operation doctor needs to cooperate with a doctor of a main knife, and holds the uterine lifting device to press down the handle of the uterine lifting device towards the direction of the operation part so as to expose the cervical side wall of the operation part. This method of exposing the cervical sidewall of the surgical site is poor: the doctor lifts the uterus and squats half and crouches and tired, cervical exposure condition is poor, and patient's perineum atress is great and probably leads to the damage.
Clinically, when the uterus lifting device with the rotatable uterus lifting head is needed to expose different parts of the cervix, the uterus lifting head is only required to rotate to an angle opposite to the operation part, and the uterus lifting head can draw the uterus towards the direction, so that the aim of exposing the side wall of the contralateral cervix can be fulfilled.
In addition, after hysterectomy, the cervix is opened, and carbon dioxide gas in the abdominal cavity is lost through the opened cervix, so that the space required by the operation is difficult to maintain in the abdominal cavity, and the operation progress is seriously affected. The current clinical solution is to pack sufficient gauze into the patient's vagina, and to plug the gas-loss orifice with gauze. The method is complicated to implement, and can cause insertion injury to the inner wall of the vagina of the patient, so that the effect is not satisfactory, and the gas loss speed is reduced.

To assist the surgical operation, a one-way film sleeve 26 can be placed in the tail end of the uterine tube 1, the one-way film sleeve 26 allows surgical instruments to be placed in the uterine tube 1, and the one-way film sleeve 26 can prevent carbon dioxide gas in the abdominal cavity from leaking through the uterine tube 1. That is, before surgical suturing, the operation cavity of the surgical instrument is provided by using the operation cavity of the uterine tube 1 to assist the operation. In the process of assisting the operation by using the uterine lifting tube 1, the sealing effect can be realized by using the uterine lifting sealing mechanism and the unidirectional film sleeve 26, the effect of carbon dioxide in the abdominal cavity can not be influenced, and the convenience and the reliability of the operation are improved.
