Description

Tissue shielding type female channel

Technical Field

The invention relates to the technical field of medical instruments, in particular to a tissue shielding type female channel.

Background

The traditional gynecological laparoscope technology adopts a pneumoperitoneum method, fully exposes the operative field, has the advantages of clear images, small wound of the abdominal wall of a patient, quick recovery and the like, and is widely applied to gynecological operations. This approach still requires multiple small incisions in the abdominal wall, leaving scars.

The traditional vaginal surgery adopts a natural channel approach, the surgical channel extends into the body of a patient, the end part far away from the extending part on the surgical channel is connected with an operation platform, the operation platform comprises surgical instruments such as an inflating device, a laparoscope and operation forceps, the surgical instruments can extend into the deep part of the vagina of the patient along the surgical channel to perform the surgery, and the mode accords with the physiological characteristics of the human body, avoids abdominal wall trauma and is more minimally invasive, so the vaginal surgery is widely applied to the gynecological surgery.

Although the existing vaginal operation using the operation channel can avoid abdominal wall trauma and has a good operation effect, the inventor finds that the existing vaginal operation using the method has the defects that:

when the operation channel is used for carrying out a vaginal operation, the operation channel is usually stretched into the vaginal fornix in the vagina of a patient, the vaginal fornix is close to the parts of the bladder, the uterus, the rectum and the like, when the operation is carried out on the bladder, the uterus or the rectum, an operation instrument is required to be stretched into the operation parts of the bladder, the uterus, the rectum and the like from the operation channel, because the patient is usually in a lying state in the operation process, the bladder and the uterus naturally droop, the separation of human tissues is not facilitated, if the patient lies on an operation table when the operation is carried out on the uterus, the bladder is close to the area where the uterus is influenced by gravity, part of the bladder occupies part of the operation area, the bladder can possibly obstruct medical personnel to carry out the operation, and the operation difficulty of the medical personnel can be increased.

Therefore, in view of the above problems, there is a need to design a vaginal canal that facilitates the blocking of tissue outside of the surgical site when the surgical canal extends into the vagina of a patient.
