Abstract

The utility model discloses an adjustable surgical retractor which comprises a left and a right half retractors (1, 2); the left and the right half retractors (1, 2) are adjustably connected at the position of a retractor handle (3), wherein, a retractor head (4) of the half retractor at one side is in a spiny structure. The length of the adjustable surgical retractor can be adjusted according to the body width of the patient or the surgical need; the spiny structure provided can be taken as a traction supporting point; and the adjustable surgical retractor is characterized by simple design, convenient operation, etc.

Description

A kind of adjustable surgery tractor

One, technical field

This utility model relates to a kind of surgical operation medical apparatus and instruments---drag hook, is specially a kind of adjustable surgery tractor.

Two, background technology

Existing posterior spinal operation is generally taked lateral position, can avoid the chest compressing because of it, improves breath state, alleviates abdominal pressure, reduces intraoperative hemorrhage, can significantly improve the corrective surgery safety.But during the lateral position operation, operator is in the face of surgical field of view, and reduce in the assistant space, and inconvenience exposes surgical field of view for the patient, particularly Wicresoft's semi-vertebral plate operation, self-retaining retractor commonly used is not because of resisting the effect that tissue can not play the tractive tissue, expose the visual field.Now generally adopt goitre retractor to draw back tissue, because different patient body width differs bigger, and goitre retractor length is fixing unadjustable, the goitre retractor that when the tractive tissue exposes surgical field of view, needs different length, increased the cost of the apparatus that makes arrangements for surgery, and in operation process, need the assistant to continue the tractive drag hook, increased assistant's the amount of labour, waste time and energy to expose the art open country.

Three, summary of the invention

This utility model is at above weak point, provide a kind of easy to operate, length can be regulated and can do the adjustable surgery tractor that the strong point draws.

For achieving the above object, the technical solution adopted in the utility model is: a kind of adjustable surgery tractor, include left and right two half hooks, and left and right two halves drag hook is adjustable connection at drag hook handle place, wherein the drag hook head of half drag hook is the thorn-like structure.

Above-mentioned adjustable surgery tractor, the face that matches on the two halves drag hook are provided with a plurality of grooves that match, and wherein half drag hook is provided with bolt on the drag hook handle, and second half drag hook is provided with slotted hole on the drag hook handle, and bolt passes slotted hole and fastening by clamp nut.

Effect intentionally of the present utility model is:

The adjustable connection of two halves drag hook can be adjusted drag hook length according to patient body width and operation needs, and the groove structure that half hook mating surface is provided with fastens mutually and joint bolt, clamp nut can make the cooperation of left and right sides half hook reach very stable status.

The thorn-like structure that is provided with on the top of drag hook can be inserted spatium interosseum, makes drag hook have the strong point when tractive is organized, and plays leverage, has more stability when organizing retracting.

During the operation of spinal column lateral position, surgical field of view top lay routinely holds the aseptic pallet of operating theater instruments temporarily, one end tractive tissue of drag hook is exposed the visual field, the other end can be hung on the aseptic pallet as countering force, do not need manpower tractive always, liberate assistant's labour force, improved the efficient of operation.

Fig. 2 is the main TV structure sketch map of the right half hook of this utility model;

Fig. 3 is the structural representation of looking up of the right half hook of this utility model;

Structural representation when Fig. 4 cooperates for drag hook.

Five, the specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of adjustable surgery tractor includes left half hook 1 and right half hook 2, and the drag hook head 4 of left half hook 1 is the thorn-like structure.

The face that matches on the two halves drag hook 1,2 is provided with a plurality of grooves that match 5, left side half hook 1 is provided with two bolts 6 on drag hook handle 3, right half hook 2 is provided with slotted hole 7 on drag hook handle 3, when the two halves drag hook cooperated, bolt 6 passed slotted hole 7 and undertaken the two halves drag hook fastening by clamp nut 8.

During use, patient's lateral position is behind the aseptic list in conventional shop, drag hook is adjusted apart from the distance at patient body edge according to otch, unscrew clamp nut 8 back pulling half hooks 1,2, adjust both to suitable length, to adapt to patient's body width or operation needs length; Tightening clamp nut 8 then fixes drag hook length; The thorn-like structure of drag hook is inserted the prominent or vertebral plate gap of joint of vertebral column appear surgical field of view as strong point tractive paravertebral muscles and soft tissue;

The other end of drag hook is hung on the aseptic pallet of surgical field of view top, and as the counteracting force of traction force, the assistant obtains liberation, can the assisting operation person carry out meticulousr operation technique, has improved operation efficient and operation quality.
