Description

Sterile protective sleeve for minimally invasive mammary gland rotary cutting needle

Technical Field

The utility model relates to the field of medical equipment, more specifically relates to an aseptic protective sheath that is used for mammary gland wicresoft to cut needle soon.

Background

The breast nodules are common benign diseases in breast diseases, are mainly treated clinically by means of surgical resection, have the advantages of less wound, short time and good aesthetic effect after operation in minimally invasive rotary-cut breast surgery, and are favored by patients.

However, in the current minimally invasive rotary cutting device for mammary gland widely used in clinic, the puncture needle is a disposable and individually packaged sterile product, and the driver handle is a reusable and non-sterile device, which need to be connected together for use. Therefore, in the preparation before the operation, the connected minimally invasive rotary cut device of the mammary gland needs to be sleeved with a sterile protective sleeve, and then the subsequent minimally invasive rotary cut operation of the mammary gland can be implemented. The conventional sterile protective sleeve used in clinical practice at present is generally a plastic sleeve, the shape and the structure of the conventional sterile protective sleeve are not suitable for a minimally invasive mammary gland rotary cutting needle, the matching performance is poor, the use is inconvenient, the loosening and the sliding are easy, the sleeving operation is complex, the operation time cost is increased, the isolation effect is poor, the pollution is easy, and the infection risk is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming at least one kind of defect of above-mentioned prior art, provide an aseptic protective sheath that is used for mammary gland wicresoft to cut needle soon for solve that conventional aseptic protective sheath uses inconvenient, the cover establishes the problem that the operation is complicated, easily pollutes.

The utility model provides an aseptic protective sheath for mammary gland wicresoft rotary cutting needle, including the syringe needle cover body and around the protective film sleeve that the syringe needle cover body entry set up, syringe needle cover body entrance is equipped with open structure, syringe needle cover body detachably connects in open structure one side, the telescopic head end of protective film is connected in the open structure opposite side. The needle head sleeve body is used for accommodating a puncture needle, the puncture needle is an aseptic part, and the puncture needle enters from the inlet of the needle head sleeve body; the protective film sleeve is used for wrapping a non-sterile part connected with the handle of the driver, and the opening structure is used for restraining the sterile protective sleeve on the puncture needle and closing the head end of the protective film sleeve so as to isolate the needle head sleeve body and the protective film sleeve from each other.

In the process of sleeving the sterile protective sleeve on the minimally invasive mammary gland rotary incision needle system, the puncture needle can directly enter from the inlet of the needle head sleeve body, so that the puncture needle is wrapped in the needle head sleeve body; the protective film sleeve is arranged around the inlet of the needle head sleeve body, so that the mounting of the minimally invasive mammary gland rotary cutting needle and the driver handle is not hindered, and the non-sterile part of the minimally invasive mammary gland rotary cutting needle can be wrapped; the opening structure enables the sterile protective sleeve to be bound on the puncture needle, and the sterile protective sleeve plays a role in fixation. The sterile protective sleeve is convenient to sleeve and simple to operate, the opening structure enables the sterile protective sleeve to be not easy to loosen and slip, and the safety is improved. The operating personnel will the syringe needle cover body is dismantled from open structure one side, can expose the pjncture needle and put into use, and convenient and fast simplifies the step, save time has improved the efficiency of preparation before the art greatly. The opening structure isolates the needle head sleeve body and the protective film sleeve from each other, plays a role in protecting the sterile puncture needle, prevents the sterile puncture needle from being polluted, isolates the sterile part from the non-sterile part, and reduces the pollution risk.

Specifically, the inner side surface of the protective film sleeve after the sheathing is finished is a non-sterile surface which is attached to a non-sterile part connecting the puncture needle and the driver handle; the outer side surface is a sterile surface which can be contacted by operators, and the requirement of sterile operation of the operation can be met.

Further, aseptic protective sheath is still including accomodating the structure, accomodate the structure and set up the side at the syringe needle cover body around the syringe needle cover body, the protection film sleeve piles up the setting and is accomodating in the structure.
