Description

A non-slip out female channel

technical field

The utility model relates to the technical field of medical devices, in particular to a non-slip-out female channel.

Background technique

When performing vaginal surgery, the natural channel is usually used to insert the surgical instruments into the patient's vagina for surgery. At the same time, it is used in conjunction with the surgical channel. The surgical channel is placed in the patient's cavity, and the operating platform is connected to the surgical channel. The operation platform is provided with surgical instruments, so that the surgical instruments can be extended into the body of the patient through the surgical channel to perform surgery.

Although using the surgical channel for vaginal surgery can reduce the trauma to the patient's body, be more minimally invasive, and have better surgical results, the inventor found that the current surgical channel still has shortcomings, specifically:

The surgical channels currently used are mostly straight cylindrical structures. After the surgical channel is extended into the human body cavity, under the contraction of the muscles in the human body cavity, the muscles squeeze the surgical channel, which will cause the surgical channel to be squeezed. Risk of slipping out of the lumen.

Therefore, based on the above problems, there is an urgent need to design a non-slip out female channel, so that when the female channel is placed in the cavity, the female channel can be prevented from slipping out under the contraction and extrusion of the muscles.

SUMMARY OF THE INVENTION

The purpose of the present utility model is: aiming at the above-mentioned deficiencies existing in the use of the current surgical channel, a non-slip-out female channel is provided, so that when the female channel is placed in the cavity, the female channel can be prevented from being damaged by the muscle. Shrink and squeeze slide out.

In order to achieve the above-mentioned purpose of the invention, the utility model provides the following technical solutions:

An anti-slip type female channel, comprising a channel body, the channel body comprising a protruding part and a connecting part, the protruding part is used to protrude into a patient's cavity, the connecting part is used to connect with an operating platform, so the The outer wall of the connecting portion is provided with a concave arc-shaped area, and the arc-shaped area is used to cooperate with the cavity tissue and can prevent the channel body from slipping out of the cavity.

As a preferred technical solution of the present application, the arc-shaped region is an annular structure surrounding the axis of the channel body.

As a preferred technical solution of the present application, the arc-shaped area is provided on the protruding portion near the connecting portion, and the arc-shaped area is used to cooperate with the tissue of the orifice.

As a preferred technical solution of the present application, on the portion of the extending portion where the arcuate region is not provided, the diameter of the outer wall of the region on the extending portion away from the connecting portion is larger than that of the extending portion The diameter of the outer wall of the area close to the connecting part.

As a preferred technical solution of the present application, on the portion of the extending portion where the arcuate region is not provided, and along the direction from the extending portion to the connecting portion, the portion of the extending portion is The diameter of the outer wall gradually decreases.

As a preferred technical solution of the present application, the connecting portion is provided with a plurality of holes, and the holes are used for sutures to penetrate, so that the connecting portion and the tissue of the orifice are sutured.

As a preferred technical solution of the present application, the holes are arranged along the circumferential direction of the connecting portion.

As a preferred technical solution of the present application, the hole is arc-shaped, and the hole includes an inlet hole end and an outlet hole end, and the inlet hole end and the outlet hole end are both arranged on the outer wall of the connecting portion, and The hole does not penetrate the connecting portion.

As a preferred technical solution of the present application, the hole is disposed near the end of the connecting portion that is far away from the protruding portion.

As a preferred technical solution of the present application, the outer wall of the protruding portion has a smooth transition.

Compared with the prior art, the beneficial effects of the present utility model:

In the solution of the present application, the female channel includes a channel body, and the channel body includes a protruding portion and a connecting portion. When using the female channel, extending the protruding portion of the female channel into the patient's vagina can make The operation platform is connected with the connecting part to facilitate vaginal surgery. At the same time, a concave arc area is arranged on the outer wall of the connecting part, so that the cavity tissue fits with the outer wall of the connecting part and is in contact with the concave arc area. The matching cavity tissue can limit the vaginal channel, so that when the muscles in the vagina contract and squeeze the vaginal channel, the concave arc area can prevent the vaginal channel from slipping out of the vagina, thereby improving the performance of the vaginal channel. The stability of the vaginal channel into the patient's vagina;

The arc-shaped area is set as a ring-shaped structure surrounding the axis of the channel body, so that after the connecting part on the female channel is put into the vagina, the vaginal tissue corresponding to the arc-shaped area can also be an annular structure, thereby improving the performance of the vagina. The area where the tissue limits the female channel further improves the stability of the female channel being placed in the patient's vagina;

The arc-shaped area is arranged on the protruding part near the connecting part. When the connecting part is put into the vagina, the arc-shaped area can be matched with the tissue of the orifice, because the cross-section of the female channel corresponding to the arc-shaped area The surface connection is small, so that the space on the vaginal channel close to the inside of the vagina is larger, which is convenient for the passage and movement of medical instruments in the subsequent vaginal surgery. It provides convenience for performing surgery;

When the medical staff sutures the connecting part and the tissue exiting from the vaginal opening, an arc-shaped suture needle is usually used. In the present application, by setting the hole in an arc shape, the degree of fit between the hole and the suture needle is improved. At the same time, the hole includes an inlet end and an outlet end, and both the inlet end and the outlet end are arranged on the outer wall of the connecting part, and the hole does not penetrate the connecting part, so that the hole is a complete channel, and the suture needle passes through the hole. The inner wall of the hole can play a guiding role, which is convenient for the suture needle to pass through the hole from the same side and then out of the hole from the same side for suture, which improves the convenience of suture for medical staff;

The hole is arranged near the end of the connecting part that is far away from the protruding part. When the female channel is put into the vagina of the patient, the connecting part is exposed to the vagina and is at the position of the vaginal opening. When the tissue of the vaginal opening is sutured, since the hole is located on the connecting part near the end of the connecting part far from the protruding part, the connected part after suture has a tendency to be pulled toward the vagina by the tissue of the vaginal opening. , which can further prevent the female channel from slipping out of the vagina, and improve the stability of the female channel when it is fixed.
