Abstract
The invention discloses a kind of cylindrical tenterhook that can regulate size, four and half curved stainless steel sheets are connected into cylinder-like structure mutually, the cohesive end that holds two inside piece in the hollow cohesive end of two lateral films respectively pushes away the size of regulating cylinder by inside piece taking out in the hollow cohesive end of lateral film.When the holding screw in two cohesive end outsides of lateral film pressed on inside piece, inside piece promptly no longer can be taken out and be pushed away and a fixation.The upper and lower of inside piece and lateral film ora terminalis respectively has pair of corresponding spacing little prominent, extracts out from the cohesive end of lateral film to prevent inside piece.Four cylinder-like structures that stainless steel substrates surrounds, its side-looking is the indent arc.
Description
The present invention relates to a kind of novel drag hook, the particularly a kind of cylindrical tenterhook that can regulate size.
Existing drag hook mainly is made up of drawing head and handle two parts, when operation is used, needs assistant's tractive to fix, the visual field that tractive appears is often undesirable, and because traction force is towards a direction, pulling force is not easy again to grasp, thereby is easy to cause the unnecessary damage of edge of wound.
Task of the present invention provides a kind of novel drag hook, it can be fixed on edge of wound comparatively easily, and the size that can regulate the art open country according to different requirements of operation, because its profile is cylindric, the traction force that can make the operative incision all directions is uniformity comparatively, has solved the firmly problem of the uneven injury of mouth of easily causing injury of manpower tractive.
The present invention is achieved in that by four and half arc high-quality stainless steel substrates and is connected into a cylindrical device mutually, the cohesive end of two lateral films is hollow for one section, the cohesive end that holds two inside piece respectively, by inside piece in the hollow cohesive end of lateral film extraction and advance the size regulate cylinder.Respectively there are two holding screws that are arranged above and below in the cohesive end of the lateral film outside, when pressing on inside piece by the silk hole on the lateral film, i.e. and fixing inside piece, making it can not be again by extracting out in the hollow cohesive end of lateral film or advancing.The upper and lower of inside piece ora terminalis respectively has square spacing little dashing forward, the ora terminalis upper and lower of lateral film also respectively has square spacing little dashing forward, when inside piece is evacuated to maximum position in the hollow cohesive end of lateral film, be that spacing little prominent on the inside piece is when getting close to spacing little prominent on the lateral film, just can not twitch (this moment cylinder reach maximum rating) again, avoid inside piece taking out fully in the hollow cohesive end of lateral film to take off.
Side-looking of the present invention is the indent arc, so that be fixed on the cutting edge.
Below in conjunction with accompanying drawing invention is described in further detail.
Fig. 1 is the transverse cross-sectional view of the present invention along the 7-7 line.
Fig. 2 is a perspective view of the present invention.
Fig. 3 is a side view outline of the present invention.
See figures.1.and.2, four and half curved stainless steel sheets are connected into a cylinder-like structure (1) mutually, the cohesive end (3) of two lateral films (2) is hollow, the cohesive end (5) that holds two inside piece (4) respectively, by inside piece (4) in the hollow cohesive end (3) of lateral film (2) extraction and advance the size regulate cylinder.Respectively there are two holding screws that are arranged above and below (7) in two cohesive end outsides of lateral film (2), when holding screw (7) presses cohesive end (5) in inside piece by the silk hole on the lateral film (2), inside piece (4) promptly no longer can be from the hollow cohesive end (3) of lateral film thus in take out and push away fixation.Upper and lower at (4) two ora terminalis of inside piece respectively has a difference square spacing little prominent (6) up and down, the upper and lower of lateral film (2) ora terminalis respectively has square spacing little prominent (8) that a difference is downward and make progress, when inside piece (4) is drawn to maximum position in the hollow cohesive end (3) of lateral film, be spacing little prominent (8) of spacing little prominent (6) and lateral film (2) of inside piece (4) when getting close to cylinder reach maximum rating, inside piece (4) promptly can not be extracted out again, thereby has avoided inside piece (4) from the interior extraction fully of the hollow cohesive end of lateral film (3).
With reference to Fig. 3.Cylinder-like structure (1) side-looking that four stainless steel substrates of the present invention surround is indent arc (9), can be fixed on the operative incision edge more conveniently.
Claims (2)
1, a cylindrical device (1) that is connected mutually by four and half curved stainless steel sheets is characterized in that:
The hollow cohesive end (3) of a, two lateral films (2) holds two inside piece (4) respectively, pushes away the size of regulating cylinder by inside piece (4) taking out in the hollow cohesive end of lateral film (2).
The upper and lower of b, inside piece (4) ora terminalis respectively has one square spacing little prominent (6), and the upper and lower of lateral film ora terminalis also respectively has one square spacing little prominent (8).
2, according to claim 1 device specifies, it is characterized in that the cylinder-like structure (1) that four stainless steel substrates surround, side-looking is indent arc (9).
