Abstract

The utility model relates to an operation auxiliary appliance, in particular to a retractor used in the orthopedic operation, mainly consisting of a fixing frame, a set of retractors and a plurality of fixing pins. The peripheral of the fixing frame is provided with pin ports with equal interval. The retractor has a row of pin holes thereon, and the retractor is fixed on the fixing frame by the fixing pin. The number of the retractor used can be selected according to the operation need or can also according to the different depth of the tissue. The utility model can avoid the tissue operation trauma effectively, increase the operation wild exposure and shorten the operation time, and also can reduce the operation trauma, avoid the operation incision infection. The utility model is easy to operate and be extended.

Description

The bone surgery retractor

This utility model relates to a kind of operation appurtenance, the retractor that especially a kind of bone surgery is used.

Bone surgery particularly position such as hip joint, thigh muscle is abundant, and operation appears, operates difficulty, needs several assistant's tractives, or use other retractor, it is many that the former participates in surgical staff, relative just increased the pollution in the operation, increased operating time; The latter's direction of draw and the degree of depth are single, the traction force quantity not sufficient, and it is insufficient that operating field appears, and influences surgical field of view and operation.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and provide a kind of tractive degree of depth, direction can adjust, reduce the operation number, operating field appears sufficient bone surgery retractor.

For achieving the above object, this utility model is to realize like this, a kind of bone surgery retractor, be characterized in, mainly form by a fixed frame, a cover tractive hook and a cover steady pin, outer placing has equally spaced semicircle lock-joint around the fixed frame, and the tractive hook is provided with row's pin-and-hole, and the tractive hook is to be fixed on the fixed frame by pin-and-hole and lock-joint with steady pin; The fixed number of tractive hook and position are not unalterable according to operative site and operation needs and fixed on the fixed frame; In addition, existing bone sled can be united use with this retractor, further to appear osseous tissue.

Above-mentioned fixed frame is generally rectangle, and the tractive hook is " 7 " shape, and steady pin then is designed to tower, and top is a tower ball, and the bottom is a tower pin that two up big and down small cylinders constitute, so that it is simple to operate, easily grasps.

Compared with the prior art this utility model can reduce the operation number of participating in, and labor savings has reduced the pollution in the operation; Can select suitable tractive hook for use according to differences such as organizing thickness, direction, tractive strength, direction etc. can be adjusted at any time, avoid pulling repeatedly or the excessive infringement that causes tissue of retractor strength in the past, strengthen operating field and appear; Shorten operating time, reduced operation wound, avoided operative incision to infect; Retractor described in the utility model is simple to operate, and is easy to use, is easy to promote.

Below in conjunction with drawings and Examples this utility model is described in further detail.

Fig. 1 is equipped with a tractive hook for this utility model and with the structural representation of broken section.

Fig. 2 is the structural representation of tractive hook.

Fig. 3 is the vertical view of Fig. 2.

Fig. 4 is the structural representation of steady pin.

As shown in Figure 1, bone surgery retractor described in the utility model, form by a rectangle fixed frame 1, tractive hook 2 and steady pin 3,10 in tractive hook 2 one covers, 4 in steady pin 3 one covers, outer placing has equally spaced semicircle lock-joint 4 around the fixed frame 1, and tractive hook 2 is to be fixed on the fixed frame 1 by pin-and-hole 5 and lock-joint 4 with steady pin 3.

Above-mentioned tractive hook 2 is " 7 " shapes, which is provided with row's pin-and-hole 5, as Fig. 2, shown in Figure 3; The tower structure form that steady pin 3 is made up of tower ball 6 and the tower pin 7 that is made of up big and down small two-layer cylinder that is connected as a single entity with it, as shown in Figure 4.

During operation, be chosen in the number of assembling tractive hook 2 on the fixed frame 1 according to position of performing the operation and the wild degree that appears, the degree of depth of its tractive, direction, strength etc. also are to adjust at any time according to practical situation, simple to operate, easy to use, have great use value, be convenient to generally promote the use of.
