Abstract
The utility model relates to a medical device for enlarging visual field in rectum operations, and is composed of a suit of diskette slot-shaped enlargement device having diverse guide head bands in different sizes, and an optical fiber inner illumination device, while the utility model can also be without the optical fiber inner illumination. In the operation time of the rectum, the appropriate enlargement device is chose by only according to the size of the affection. The affection can be pulled and opened to expose the visual field of the affection as long as the utility model is inserted into the anus. The positioning can be realized by the personal adhesive force and the gravity of the device with no need of the manual drag and regulation, and the support of the hands is not needed. When required, the optical fiber inner illumination can be adopted to realize the shadowless illumination. The utility model is the novel, handy and convenient device in the rectum operations having clear and bright visual field, and convenient operation.
Description
This utility model is the medical operation apparatus.The anorectum surgical field of view displaying unit that specifically uses in the anal-surgery.
In the surgery directly view operative process, cutting, stop blooding, appear surgical field of view and stitching is the most basic step of performing the operation.Fully appearing surgical field of view, is again the key that ensures that operation is successful.At present, during per anum operation at home and abroad, or directly draw with drag hook by surgical staff, or perform an operation with being similar to the adjustable retractors such as breast support device that vaginal speculum that gynecological uses or similar division of chest disease use, but because the weight and volume of adjustable part, it is automatically fixing or put in place to make apparatus be difficult in operative site, still need the assistant with apparatus for a long time with the hand steered maintenance of holding, thereby do not have the carrying out that shortcoming influence such as intraoral illumination is performed the operation again.For overcoming above-mentioned defective, save the adjustable part of apparatus, make apparatus light and handy easily fixing, and the adjustability that operation needs is finished by the external member that varies in size, also be convenient to the stitching of performing the operation, when throwing light on, needs can add optical fiber, in view of the above, made this utility model.
Accompanying drawing is a sketch map of the present utility model.
This utility model is made up of guide head, flute profile device, limiting plate, fiber illumination device.1 is guide head among the figure, play the guiding role, and the 2nd, the flute profile device, three side sealing closes, and we opens one side, and affected part just reveals at this, the visual field is big especially, collapses too tightly for not making body, influence operation and stitching, three of flute profile are adopted the plane, and the 3rd, limiting plate plays position-limiting action, hander 4,5th is arranged on it, and fiber illumination device forms no shadow effect, bonder is tied optical fiber and cold light source, can make surgical field of view that enough illumination is arranged.This utility model uses simple, as long as according to the anus size; Select for use through suitable we of disinfectant and drive device, insert anus, affected part just reveals naturally.Must not hold simultaneously with hand steered, not manually tractive and adjusting, operator can be worked freely.
This utility model can be used routine disinfection, and fiber device also can be complementary with the cold light source luminaire of existing hospital, is a kind of simple to operate, the convenient and practical desirable apparatus that needn't lack in anal-surgery.
Embodiment:
Overall dimensions length L of the present utility model is 110mm; Wide B is a third gear, is 27,30 respectively, 33mm; High H also is that third gear 22,24,26mm are corresponding with B respectively, forms large, medium and small specification, and the above special-shaped of length 200mm also can be arranged.Dish type size 80mm, 60～100 * 30 ° of mm of hander size are trapezoidal.On fiber illumination device is arranged, but strip length 1500mm, inlet fibre diameter are the optical cable of 3mm, the light that is sent by cold light source throws light on by optical cable, and we drives device, makes whole visual field high-visible, also can not be with optical cable, outer light local lighting.
