Abstract

The utility model discloses a drag hook, comprising a main drag hook and a secondary drag hook which is rotatable and is arranged on the main drag hook. A rotatable swivel block is also arranged on the main drag hook, and the secondary drag hook is arranged on the swivel block and is capable of sliding along the swivel block. Because the drag hook of the structure employs the combination structure of the main drag hook and the secondary hook, the secondary drag hook is capable of rotating, the usage of the utility model is convenient, the surgical field is widened, the duration of surgery is shortened and the number of assistants is reduced. The swivel block is arranged on the main drag hook, and the secondary drag hook is arranged on the swivel block and is capable of sliding along the swivel block, thereby enabling the secondary drag hook to have to functions of rotating and stretching.

Description

A kind of drag hook

Technical field

This utility model relates to technical field of medical instruments, is specifically related to a kind of operation drag hook.

Background technology

Drag hook is a medical apparatus and instruments commonly used in the surgical operation.When carrying out abdominal operation, need draw back stomach wall and other organ or tissue to both sides clinically, so that expose surgical field of view with drag hook.But the drag hook that now generally uses is the single drag hook of bar shaped, in use, especially when the more fat patient of the bodily form uses on one's body, its fatty tissue, bladder or intestinal tube etc. can be from two side inflow surgical field of view of drag hook, thereby the carrying out of influence operation, prolonged the time of operation, increased unnecessary misery to patient.When running into this kind situation, need increase drag hook again the organ that flows into the visual field is drawn back, also will increase paraprofessional personnel's number sometimes.

The utility model content

The technical problems to be solved in the utility model is that the drag hook at present use exists other organ to flow into surgical field of view easily and needs the more deficiency of assistant, provides a kind of and can make the drag hook that surgical field of view is open and can reduce assistant's number and can shorten operating time.

In order to solve the problems of the technologies described above, this utility model provides a kind of drag hook of following structure, and this drag hook comprises main drag hook, is provided with rotating secondary drag hook on main drag hook.

Adopt the drag hook of said structure, owing to adopt the combinative structure of major and minor drag hook, secondary drag hook can rotate, and is therefore easy to use, and the open surgical field of view of energy can shorten operating time and reduce assistant's number.

Convenient in order to use, on main drag hook, be provided with rotating spill spin block, spill spin block is provided with slidably secondary drag hook.Its secondary drag hook of the drag hook of this structure has rotation and flexible two kinds of functions.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a vertical structure sketch map of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 be Fig. 1 along the A-A line cutaway view;

Fig. 4 is the structural representation of a kind of user mode of this utility model.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, this utility model is made up of the secondary drag hook 3 of main drag hook 1 and its both sides.Main drag hook 1 is provided with rotating spill spin block 2, and spill spin block 2 is connected on the main drag hook 1 by bearing pin 4, and spill spin block 2 can rotate around bearing pin 4 also can be stable in arbitrarily angled maintenance; Spill spin block 2 is provided with chute, and secondary drag hook 3 is contained in the chute and can slides in chute, and spill spin block 2 is provided with the screw 5 of fastening secondary drag hook 3.Secondary drag hook 3 can be directly be contained on the main drag hook 1 by bearing pin, but preferably is contained on the main drag hook 1 by spill spin block 2, can make secondary drag hook have rotation and flexible two kinds of functions like this.

During use, can regulate the angle of secondary drag hook 3 arbitrarily as the case may be, also can elongate or shorten secondary drag hook 3.State when Fig. 4 has provided a kind of the use, its secondary drag hook that is positioned at main drag hook 1 front shortens and turns over certain angle clockwise, is positioned at the secondary drag hook elongation at main drag hook 1 back side and turns over certain angle counterclockwise.
