Abstract

The invention relates to a medical appliance, in particular to a parallel surgical spreader which comprises parallel handles, pulleys, sliding chutes, stretching handles, a rotating shaft, an annular holder and clamp handles, wherein the two parallel handles which are parallel to each other are positioned at the left and right sides of an X-shaped frame formed by the two stretching handles, and the pulleys at the end parts of the two stretching handles are respectively positioned in the sliding chute of the parallel handle on the same side and can freely slide along the sliding chute. The pulleys at the lower ends of the two stretching handles are respectively connected with one end of the two clamp handles and are in rotating movable fit, the shaft is arranged at the intersection of the two clamp handles, and the two clamp handles are connected with the shaft and are in rotating movable fit with the shaft. The invention realizes that the incision can be pulled under the condition that the parallel handles are parallel to each other, thereby greatly widening the surgical field and improving the surgical quality compared with the prior art.

Description

Run-in index operation dilator

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of run-in index operation dilator.

Background technology

In the operation, one exposes good surgical field of view all is vital to any one operation process.The exposure apparatus hands formula drag hook that is used at present performing the operation is the most frequently used, and when using the drag hook tractive, because drag hook and operative incision edge mostly are and contact, therefore, usually each drag hook can only go out a leg-of-mutton surgical field of view by tractive, reach openr surgical field of view, need many handss a plurality of points of operation notching edge to be carried out tractive simultaneously with a plurality of drag hooks, and such operation be waste time and energy, unusual inconvenience.

Summary of the invention

The present invention is the solution the deficiencies in the prior art, the run-in index operation dilator that provides a kind of one-handed performance just can obtain open surgical field of view.

The scheme that solves the technology of the present invention problem is: run-in index operation dilator is by parallel shank, pulley, chute, Telescopic handle, rotating shaft, ring is constituting with the pincers handle, wherein, the mid point of the Telescopic handle of two vertical bar shapeds all is connected with rotating shaft and becomes rotation to concern movingly with rotating shaft, the two ends of each bar Telescopic handle have one to become the rotation pulley of relation movingly with Telescopic handle respectively, parallel shank is the bar shape that has a chute, article two, the parallel shank that is parallel to each other is in the left and right sides of the X-shaped framework that two Telescopic handles constitute, and the pulley of two Telescopic handle ends is in the chute of the parallel shank of homonymy with it respectively and can be free to slide along chute.The pulley of two Telescopic handle lower ends is connected with an end of two pincers handles respectively and becomes rotation to concern movingly, it is holistic semiorbicular ring handle that the other end of two pincers handles has with clamping handle respectively, there is a rotating shaft at place, two pincers handle cross points, and two pincers handles all are connected with rotating shaft and become rotation to concern movingly with rotating shaft.

Earlier singlehanded when strutting the visual field in operation two pincers handles are closed up, insert incision, separately, because two pincers handles and two rings are a parallelogram that constitutes, therefore, two parallel shank remain the state that is parallel to each other in separation process with two rings for reuse thumb and cross.

Adopt such scheme, can reach following effect:

Because the present invention can make parallel shank under situation about being parallel to each other otch be carried out tractive, compared with prior art, has enlarged surgical field of view greatly, improved the quality of operation.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Among the figure: 1. parallel shank 2. pulleys 3. chutes 4. Telescopic handles 5. rotating shafts 6. rings are 7. pincers handles

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

Run-in index operation dilator is by parallel shank 1, pulley 2, chute 3, Telescopic handle 4, rotating shaft 5, ring constitutes 6 with pincers handle 7, wherein, the mid point of the Telescopic handle 4 of two vertical bar shapeds all is connected with rotating shaft 5 and concerns movingly with 5 one-tenth rotations of rotating shaft, the two ends of each bar Telescopic handle 4 have respectively one with 4 one-tenth of the Telescopic handles rotation pulley 2 of relation movingly, parallel shank 1 is the bar shape that has a chute 3, article two, the parallel shank 1 that is parallel to each other is in the left and right sides of the X-shaped framework that two Telescopic handles 4 constitute, and the pulley 2 of two Telescopic handles, 4 ends is in the chute 3 of the parallel shank 1 of homonymy with it respectively and can be free to slide along chute 3.The pulley 2 of two Telescopic handles, 4 lower ends is connected with an end of two pincers handles 7 respectively and becomes rotation to concern movingly, it is that holistic semiorbicular ring is 6 that the other end of two pincers handles 7 has with clamping handle 7 respectively, place, two pincers handle 7 cross points has a rotating shaft 5, two pincers handles 7 all to be connected with rotating shaft 5 and concerns movingly with 5 one-tenth rotations of rotating shaft.

Elder generation is singlehanded when strutting the visual field in operation closes up two pincers handles 7, insert incision, reuse thumb and cross separate two rings to 6, because two pincers handles 7 and two rings are 6 parallelogrames that constitute, therefore, two parallel shank 1 remain the state that is parallel to each other in separation process.

Claims

1. run-in index operation dilator, by parallel shank, pulley, chute, Telescopic handle, rotating shaft, ring is constituting with the pincers handle, it is characterized in that: the mid point of the Telescopic handle of two vertical bar shapeds all is connected with rotating shaft and becomes rotation to concern movingly with rotating shaft, the two ends of each bar Telescopic handle have one to become the rotation pulley of relation movingly with Telescopic handle respectively, parallel shank is the bar shape that has a chute, article two, the parallel shank that is parallel to each other is in the left and right sides of the X-shaped framework of two Telescopic handles formation, the pulley of two Telescopic handle ends is in the chute of the parallel shank of homonymy with it respectively and can be free to slide along chute, the pulley of two Telescopic handle lower ends is connected with an end of two pincers handles respectively and becomes rotation to concern movingly, it is holistic semiorbicular ring handle that the other end of two pincers handles has with clamping handle respectively, there is a rotating shaft at place, two pincers handle cross points, and two pincers handles all are connected with rotating shaft and become rotation to concern movingly with rotating shaft.
