Abstract

The utility model discloses a double-ended thyroid retractor, which comprises a first end part, a handle and a second end part, wherein one end of the handle is fixedly connected with the first end part; the handle is provided with a lightening hole; and the second end part is fixedly connected with the other end of the handle. The double-ended thyroid retractor consists of double retractor ends which can be randomly switched to use according to surgical requirements, so that convenience is brought to surgical operation; and by additionally arranging the lightening hole, the double-ended thyroid retractor has good tensile and lightening performance.

Description

The double end goitre retractor

Technical field

This utility model relates to technical field of medical instruments, be specifically related to a kind of for tracheotomy the double end goitre retractor of time traction otch or parathyroid tissue.

Background technology

Goitre retractor appears the necessary apparatus of operating field when being the thyroid surgical operation.At present the goitre retractor of using in operation single head structure normally namely has only a drag hook head, but need be according to the fat thickness of knife edge length and the edge of a knife to change the drag hook of different size when performing the operation, and the utensil of single ended retractor can make troubles to operation technique like this; In addition, goitre retractor bears certain pulling force and gravity when operation is used effect, the handle of goitre retractor is solid in the prior art, thereby effect is not good enough aspect tension and loss of weight.

The utility model content

For overcoming above-mentioned the deficiencies in the prior art, this utility model provides a kind of double end goitre retractor, and it is made of two drag hook heads, can arbitrarily use instead according to the operation demand, offers convenience to operation technique; Set up lightening hole simultaneously, made this double end goitre retractor possess good tension and loss of weight performance.

For realizing above-mentioned purpose of the present utility model, double end goitre retractor of the present utility model comprises: first head; The handle that one end is fixedlyed connected with first head which is provided with lightening hole; And second head of fixedlying connected with the handle other end.

Further, described first head and the vertical described Handle axis of described second head also are bent downwardly and have free end respectively, and described free end is to described handle inside bend.

Further, described handle mid portion both sides are curved, and the shape of described lightening hole is corresponding with described arc.

Preferably, the longitudinal length of described handle is 200mm～210mm, and the longitudinal length of described first head is 35mm～45mm, and the longitudinal length of described second head is 25mm～35mm.

Particularly, the longitudinal length of described handle is 202mm, and the longitudinal length of described first head is 39mm, and the longitudinal length of described second head is 29mm.

Preferably, being fixedly connected as to be fixed as one and being connected between described first head and described second head and the described handle.

Preferably, described first head, second head and handle are made by rustless steel.

Particularly, described rustless steel is 20Cr13 or 06Cr19Ni10 rustless steel.

Compared with prior art, the utlity model has following advantage:

1) double end goitre retractor of the present utility model makes and can arbitrarily use instead according to demand in operative treatment by the drag hook head of different size is set at the handle two ends, offers convenience to operation technique;

2) double end goitre retractor of the present utility model makes this double end goitre retractor possess good tension and loss of weight performance by setting up lightening hole at handle;

3) double end goitre retractor smooth surface of the present utility model, no cutting edge of a knife or a sword rib, no burr, no spot have good anti-corrosion.

Below in conjunction with accompanying drawing double end goitre retractor of the present utility model is described in further detail.

Description of drawings

Fig. 1 is the structural representation of this utility model double end goitre retractor;

Fig. 2 is the front view of double end goitre retractor shown in Figure 1;

Fig. 3 is the vertical view of double end goitre retractor shown in Figure 2.

Description of reference numerals: 11-first head; 12-second head; 111,121-free end; 2-hands handle; The 3-lightening hole.

The specific embodiment

As shown in Figure 1, double end goitre retractor of the present utility model comprises the handle 2 that first head, 11, one ends are fixedlyed connected with first head 11, second head 12 which is provided with lightening hole 3 and fixedly connected with handle 2 other ends.

Particularly,

first head

11 and 2 of second head, 12 vertical handles also are bent downwardly and have free end 111,121 respectively, and free end 111,121 is to handle 2 inside bend.Handle 2 mid portion both sides are curved, and the shape of lightening hole 3 is corresponding with described arc.Consider the actual therapeutic demand, the longitudinal length of handle 2 is preferably 200mm～210mm, preferably 202mm; The longitudinal length of first head 11 is preferably 35mm～45mm, preferably 39mm; The longitudinal length of second head 12 is preferably 25mm～35mm, preferably 29mm.Fixedlying connected between first head 11 and second head 12 and the handle 2 is preferably fixedly connected, and the connection that preferably is fixed as one is so that connecting portion is firm, indeformable.Consider whole tension and the loss of weight performance of this utility model double end goitre retractor, first head 11, second head 12 and handle 2 are preferably made by rustless steel, preferably 20Cr13 or 06Cr19Ni10 rustless steel.

As Fig. 2, shown in Figure 3, the specification of this utility model double end goitre retractor and parameter such as following table:

Unit: millimeter

						Goitre retractor	39×11	202	39	29	11

The occupation mode of double end goitre retractor and traditional drag hook is similar, and just two drag hook heads can switch use according to the treatment demand in operation, simple and convenient.

Double end goitre retractor of the present utility model makes and can arbitrarily use instead according to demand in operative treatment by the drag hook head of different size is set at the handle two ends, offers convenience to operation technique; The double end goitre retractor makes this double end goitre retractor possess good tension and loss of weight performance by setting up lightening hole at handle; In addition, double end goitre retractor smooth surface of the present utility model, no cutting edge of a knife or a sword rib, no burr, no spot have good anti-corrosion.

Although above this utility model has been done detailed description, be not limited thereto, those skilled in the art can realize by other embodiment that does not break away from its spirit or essential feature.Therefore, all various modifications of carrying out according to the interior perhaps principle of this utility model record all should be understood to fall into protection domain of the present utility model.
