Technical Field

The utility model relates to the technical field of medical equipment, especially a vaginal operation protection device of gynaecology.

Background

In gynecological surgery, when a vaginal hysteromyoma excision or a total hysterectomy is performed, the specimen is taken out from the vagina or the vaginal stump in the most common mode at present, but when the specimen is large, the specimen cannot be directly taken out through the vagina, and the specimen needs to be cut into small pieces to be taken out.

In the cutting process, cervical and vaginal tissues are easily damaged, scattered tissue specimens can cause the implantation and transfer of lesions, and the operation risk is increased.

SUMMERY OF THE UTILITY MODEL

The invention of the utility model aims to: in the operation of the vagina formula, in order to avoid surgical instruments to cause the injury to the vaginal tissue, avoid the scattered sample to cause the risk of planting the transfer, provide a vaginal operation protection device of gynaecology, the device can protect non-operative position such as vaginal wall effectively.

In order to realize the purpose, the utility model discloses a technical scheme be:

a gynecological vaginal operation protection device comprises a protection tube, a plurality of elastic sheets, a base and a protection film; the inner wall of the protection tube is radially provided with a plurality of clamping grooves, the elastic sheet is limited in the clamping grooves, and the elastic sheet can move along the axial direction of the protection tube; the length of the elastic sheet is greater than that of the protection tube; the rear end of the elastic sheet is fixed on the base; the protective film is arranged between the adjacent elastic sheets; promote the base is close to when the protection tube rear end, a plurality of shell fragment front ends stretch out the protection tube front end and to keeping away from protection tube axis direction expandes, the protection film is in the shell fragment pulling expandes down and is the horn mouth form.

When the protection tube is used, the protection tube supports the vaginal wall through the vagina, the front end of the protection tube extends into the abdominal cavity, the base is pushed to move towards the human body, the front end of the elastic sheet extends out of the front end of the protection tube, the original shape of the elastic sheet is recovered under the action of elastic deformation, the front end of the elastic sheet is unfolded around, the protection film connected between the adjacent elastic sheets is driven, a horn mouth-shaped opening is formed, and half-coating of tissues to be treated is achieved. When the front end of the elastic sheet extends to the maximum stroke, one side of the protective film far away from the front end of the elastic sheet is still in the protective tube. When a tissue sample is cut or the like, fragments fall into the bell-mouth-shaped opening and are discharged out of the body through the protective tube, and the fragments do not contact surrounding tissues. The surgical instruments are operated in the protective device, and the surrounding tissues are not easy to be damaged.

As the preferred scheme of the utility model, a plurality of shell fragments evenly distribute around the inner wall of protection tube.

As the preferred scheme of the utility model, the elastic sheet-shaped stainless steel sheet or elastic plastic sheet is preferred to the shell fragment.

As a preferable embodiment of the present invention, the protective film is an elastic film.

The protective film is an elastic film, so that the protective film can be conveniently put into the protective tube before and after use, and the occupied space is reduced. The elastic film is preferably an elastic rubber film.

As the preferred scheme of the utility model, the resilience force of shell fragment is greater than the resilience force of protection film.

Under the condition that the resilience force of the elastic sheet is greater than that of the protective film, the front end of the elastic sheet extends out of the front end of the protective tube and is easier to unfold into a horn mouth-shaped structure.

As the utility model discloses a preferred scheme still includes stop device, stop device connects the protection tube with the base can lock the protection tube with the interval distance of base.

The distance between the base and the protection tube is limited, the length of the elastic sheet extending out of the front end of the protection tube is further limited, and the formed horn mouth-shaped structure is more stable in the using process.

As the utility model discloses a preferred scheme still includes the locking rope, shell fragment front end tip is equipped with the aperture, locking rope one end is fixed at one of them shell fragment front end tip, and after the other end passed the aperture of other shell fragment front end tips earlier, then passed the protection tube stretches out the protection tube rear end.

When needing, the accessible is dragged locking rope rear end for the front end gathering of a plurality of shell fragments is in the same place, realizes the complete encirclement to the tissue sample.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model provides a gynaecology's cloudy formula operation protection device can realize when the cloudy formula operation, the separation of treating tissue specimen and other tissues, realizes the protection to healthy tissue.

2. The horn mouth-shaped structure is arranged, so that the specimen fragments fall into the device and are discharged out of the body, other healthy tissues are not easily contacted, and the planting transfer is avoided.

3. Under the protection of the device, when other surgical instruments are operated, the worry is less, the operation time is greatly reduced, and the burden of an operator is lightened.
