Preferably, described protective sleeve is provided with the easy-torn line of being convenient to tear vertically.
Preferably, the longitudinal size of described handle is 120mm~220mm, and the longitudinal size of described first head is 35mm~48mm, and the longitudinal size of described second head is 27mm~39mm.
Particularly, the longitudinal size of described handle is 120mm, 216mm or 220mm, and the longitudinal size of described first head is 35mm, 45mm or 48mm, and the longitudinal size of described second head is 27mm, 36mm or 39mm.
Preferably, the radial dimension of described handle end is 10mm~14mm.
Preferably, describedly be fixedly connected as the connection that is fixed as one.
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) this utility model double end goitre retractor makes drag hook not be subjected to outside contamination by sheathed protective sleeve, has avoided growing of pathogenic bacteria;
2) this utility model double end goitre retractor arranges the drag hook head of different size at the handle two ends, is convenient to using instead at any time in the operative treatment, offers convenience to operation technique;
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 and tensile strength.
Below in conjunction with accompanying drawing double end goitre retractor of the present utility model is described in further detail.

The specific embodiment
First embodiment
As Fig. 1 and Fig. 3~shown in Figure 5, double end goitre retractor of the present utility model comprises mid-handle 1, first head 21 and second head 22 of fixedlying connected respectively with mid-handle 1 two ends and be sleeved on first head 21 and second head 22 on protective sleeve 3.
Particularly, first head 21 and 1 of second head, 22 vertical handle also are bent downwardly and have free end respectively, and free end is to handle 1 inside bend.Protective sleeve 3 is made of two splits that are set in respectively on first head 21 and second head 22, each split one end sealing, the other end is sealedly connected on the handle 1 so that first head 21 and second head 22 of when operation contact otch and handle 1 two end portions keeps clean, totally; Remove protective sleeve 3 during for ease of operation, be axially arranged with the easy-torn line of being convenient to tear 31 along protective sleeve 3.Because of the demand difference, the dimensions of handle 1, first head 21 and second head 22 is also different during actual operation, and one of the present utility model preferably is made as 120mm~220mm with the longitudinal size of handle 1, preferably 120mm, 216mm or 220mm; The longitudinal size of first head 21 is made as 35mm~48mm, preferably 35mm, 45mm or 48mm; The longitudinal size of second head 22 is made as 27mm~39mm, preferably 27mm, 36mm or 39mm; In addition, the radial dimension of handle 1 end can be preferably 10mm~14mm.
A kind of preferred specification and the parameter of this utility model double end goitre retractor are as shown in the table:
Unit: millimeter
For making double end goitre retractor smooth surface, no cutting edge of a knife or a sword rib, no burr, no spot, mid-handle 1 and first head 21 and second head 22 fixedly connected is preferably to be fixed as one and is connected; Because of double end goitre retractor contact otch and parathyroid tissue when performing the operation, so drag hook also need have good anti-corrosion, a kind of preferably first head 21, second head 22 and handle 1 can be made by rustless steel, preferably 20Cr13 or 06Cr19Ni10 rustless steel.
The use of this utility model double end goitre retractor is fairly simple; choose the drag hook of different size; tear protective sleeve 3 and it is removed along easy backguy 31 usefulness on the protective sleeve 3 fingers or other sharp tools; because the seal protection of protective sleeve 3; handle 1 two end portions of first head 21 of double end goitre retractor, second head 22 and contact cutting part keeps clean, health, and can be directly used in operative treatment this moment with the double end goitre retractor.
Second embodiment
Fig. 2 shows the another kind of preferred structure of this utility model double end goitre retractor, and itself and the first embodiment difference are that protective sleeve 3 is as a whole, its closed at both ends and being set on first head 21, second head 22 and the handle 1.For ease of removing, protective sleeve 3 axially also is provided with easy-torn line 31 along it.Second embodiment can play the beneficial effect identical with first embodiment equally, namely guarantees cleaning, the health of first head 21 and second head 22 and handle 1.
This utility model double end goitre retractor makes drag hook not be subjected to outside contamination by sheathed protective sleeve 3, has avoided growing of pathogenic bacteria; First head 21 and second head 22 of different size are set at handle 1 two ends, are convenient to using instead at any time in the operative treatment, offer convenience to operation technique; In addition, this utility model double end goitre retractor smooth surface, no cutting edge of a knife or a sword rib, no burr, no spot have good anti-corrosion.
