Description

A kind of tractive distraction forcep

Technical field

This utility model relates to and belongs to medical instruments field, is exactly a kind of tractive distraction forcep.

Background technology

In surgical procedure, sometimes skin drawing is exposed；Often use tweezers or pliers that skin carries out clamp tractive to open so that observing or performing the operation.At present, using the pliers with fixing tooth when tractive struts, owing to pliers tip lengths is fixed, when needing when deeper skin is internal or tissue struts, pliers end is difficult to touch, and operating process is complicated, easily touches normal skin or tissue, damages.Strut mouth bigger time, owing to end development distance is limited, operation inconvenience, even cannot use.

Utility model content

For solving the problems referred to above, the purpose of this utility model is to provide a kind of tractive distraction forcep.

This utility model for achieving the above object, is achieved through the following technical solutions:

A kind of tractive distraction forcep, including two clamp handles, clamp handle is made up of left clamp handle and right clamp handle, in the middle part of left clamp handle and right clamp handle hinged, fixing tooth is set in left clamp handle, right clamp handle arranges fixing groove, fixing tooth and fixing slot fit, the end of clamp handle is the expansion link of at least two joints, and the end of every pole of expansion link arranges tractive hook or drawing plate.

For realizing the purpose of this utility model further, it is also possible to by the following technical solutions: the cross section of every pole of described expansion link is annular, oblate annular or C font.Arranging locking device on described expansion link, locking device is become by spring, set of balls, and groove is offered in the bottom of movable every pole of expansion link, and spring is arranged in groove, and ball is positioned at the notch of groove, and ball is fixing with groove to be connected.Arranging at least one cannelure in the every pole of described expansion link, ball coordinates with cannelure.Arranging at least one ball-type hole in the every pole of described expansion link, ball coordinates with ball-type hole.At least one tractive hook is set on described drawing plate.

The utility model has the advantage of: the end of tractive distraction forcep described in the utility model is Telescopic rod structure, expansion link can stretch out corresponding length as required, tractive hook or drawing plate on expansion link can coordinate with skin or tissue, strutted by opening, it is simple to observe and perform the operation.During for the operation of the deeper part in skin inside or tissue, can directly go deep into contact, it is to avoid touch other normal segments, it is to avoid the injury in operation process, simple operation.During for needing to strut bigger mouth, end development distance under taking out open state is relatively big, big mouth can be carried out tractive and strut.This utility model also has advantage compact, cheap for manufacturing cost and easy to use simple for structure.

Detailed description of the invention

A kind of tractive distraction forcep, as depicted in figs. 1 and 2, including two clamp handles, clamp handle is made up of left clamp handle 1 and right clamp handle 2, hinged in the middle part of left clamp handle 1 and right clamp handle 2, and left clamp handle 1 arranges fixing tooth 4, fixing groove 7 is set in right clamp handle 2, fixing tooth 4 and fixing groove 7 coordinate, and the end of clamp handle is the expansion link 9 of at least two joints, and the end of every pole of expansion link 9 arranges tractive hook 3 or drawing plate 11.Often at least one, the tractive hook 3 on joint.The end of holding of clamp handle arranges finger ring 8.The end of tractive distraction forcep described in the utility model is Telescopic rod structure, and expansion link can stretch out corresponding length as required, and tractive hook 3 or drawing plate 11 on expansion link can coordinate with skin or tissue, strutted by opening, it is simple to observe and perform the operation.During for the operation of the deeper part in skin inside or tissue, can directly go deep into contact, it is to avoid touch other normal segments, it is to avoid the injury in operation process, simple operation.During for needing to strut bigger mouth, end development distance under taking out open state is relatively big, big mouth can be carried out tractive and strut.

The cross section of every pole of described expansion link 9 is annular, oblate annular or C font.As shown in Figure 4, cirque structure is simple, produces from making conveniently.As it is shown in figure 5, contact area when tractive struts can be increased at the flat horizontal surface of oblate annular, it is adaptable to the operation of big opening.As shown in Figure 6, in the cross section of C font, tractive hook 3 or drawing plate 11 are recoverable to the notch of C font, and under retracted mode, length is less, it is simple to carry.

As it is shown in fig. 7, use interference fit between expansion link 9, extension elongation can be spacing by frictional force each other, but during interference fit, pull requires that dynamics is relatively big, uses inconvenience.In order to overcome the problems referred to above, as shown in Figure 8, described expansion link 9 arranges locking device, locking device is made up of spring 10, ball 6, and groove 5 is offered in the bottom of movable every pole of expansion link 9, and spring 10 is arranged in groove 5, ball 6 is positioned at the notch of groove 5, and ball 6 is fixing with groove 5 to be connected.After the motion bar of expansion link 9 pulls out, when exceeding the port fixing bar of ball 6, ball 6 coordinates with port, it is to avoid motion bar is retracted；During retraction operation, ball 6 is pressed inward against, expansion link 9 can be retracted.

As it is shown in figure 9, arrange at least one cannelure 12 in the described every pole of expansion link 9, ball 6 coordinates with cannelure 12, and in cannelure 12 facilitates expansion link, bar rotates, convenient fine setting.The motion bar extension elongation of expansion link 9 is controlled, can need to pull out the motion bar of different length according to operation, and every section of extension elongation can be fixed, it is to avoid retracts or excessively elongates.When taking out or retract, ball 6 the most firmly can be made to retract, complete draw process.Arranging at least one ball-type hole in the described every pole of expansion link 9, ball 6 coordinates with ball-type hole.Each ball-type hole is for be vertically arranged in order.

Drawing plate 11 skin-friction force is less, easily occurs landing situation during use, in order to overcome the problems referred to above, as it is shown on figure 3, arrange at least one tractive hook 3 on described drawing plate 11.

The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.The technology contents of the most detailed description of this utility model is known technology.
