This utility model relates to a kind of scalp clip applying forceps, particularly a kind ofly does the semi-automatic scalp clip applying forceps that craniocerebral operation is used, and belongs to the medical apparatus and instruments of brain operation usefulness.

At present, the domestic apparatus of doing the craniocerebral operation use is a minute body structure, i.e. scalp clip and operating forceps.When performing an operation, the operator people takes scalp clip on the other hand, take operating forceps on the other hand, with forceps channel one by one in the slot of insert head leather wallet, and it is strutted, the scalp for the treatment of clamping is placed in the scalp clip mouth, unclamp pliers, scalp is promptly clamped when unloading pliers, and the operator people puts in forceps channel in the slot of scalp clip once more, struts, unloads.The weak point of this apparatus and operating process is: manipulating trouble wastes time and energy.Operating time is long slightly, is pressed from both sides the position edema takes place, and the scalp of edema can be full of whole spaces of scalp clip, during unloading clip, be difficult to pliers is put in the square hole, even put in reluctantly, when strutting scalp clip, often scalp is choked, tears, cause unnecessary damage.

External product is disposable product, and too high cost has increased surgery cost, is unexpectedly accepted by the patient.

The purpose of this utility model is to overcome many deficiencies of prior art and provides a kind of and can before art scalp clip be put in the scalp grip box in advance, when cutting scalp, clamps the scalp position continuously apace and undergos surgery.Outside with the semi-automatic scalp clip applying forceps that unloads the clamp unloading clip when needing unloading clip from scalp.

The purpose of this utility model is achieved in that and comprises lower house, and its afterbody has a square opening, and the scalp grip box is positioned at housing, and its structural feature is: the head of scalp grip box has a groove; Scalp clip is positioned at the scalp grip box, with the clamping mutually of scalp grip box, with its access section be a boss, boss matches with the groove size of scalp grip box head, porose on the arc surface up and down of scalp clip, the projection press fit that Kong Yuqi afterbody scalp clip stretches out makes the scalp clip bunchiness shape that overlaps in the scalp grip box; Projectile is positioned at the back of scalp clip, and its both sides are respectively equipped with spring leaf, and a slice and lower house are close, and another sheet and upper shell are close.

The purpose of this utility model can also realize by following technical measures:

Its upper shell is provided with slideway.Under the effect of slideway, the scalp grip box moves to the clamp afterbody.

The utlity model has following advantage compared to existing technology:

1, uses this utility model can shorten 2-3 times of operating times, obviously alleviated operator people's workload.

2, can thoroughly solve the difficulty that prior art lacks folder, the phenomenon of having stopped to tear scalp.

3, because this clamp can repeatedly use, compare with external product, cost saving is remarkable.Japanese product is every to be the pincers selling price 300 yuans, and every surgery cost need then increase surgery cost and be 1200-1500 yuans with 4-5.300 yuans, access times then increase by 24 yuan-30 yuans of surgery cost in 50 times to this utility model by every.Be 2%-2.5% of external product.

The explanation of accompanying drawing drawing:

Fig. 1 is this utility model structural representation.

Fig. 2 is that scalp clip is at the intravital location drawing of box.

Fig. 3 is that A-A of Fig. 1 is to profile.

Fig. 4 is that B-B of Fig. 1 is to profile.

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

This utility model is made up of parts such as scalp grip box 1, scalp clip 2, projectile 3, lower house 4, upper shell 5, leaf spring 6, extension springs 7.Its afterbody has a square opening, and scalp grip box 1 is positioned at lower house 4,5.The head of scalp grip box 1 has a groove; Scalp clip 2 is execution units, with the bigger material manufacture of elasticity.Be positioned at scalp grip box 1, with scalp grip box 1 clamping mutually, for increasing the contact surface of scalp clip 2 and scalp, its branch interface of dehiscing is made the C type.Make a boss with its access section, boss matches with the groove size of scalp grip box 1 head, projection 11 press fit porose on the arc surface up and down of scalp clip 2, that Kong Yuqi afterbody scalp clip 2 stretches out make scalp clip 2 overlap bunchiness shape such as Fig. 2 in scalp grip box 1.Projectile 3 is as Fig. 3, and it is a critical component of the present utility model, is positioned at the back of scalp clip 2, and its effect is to come directly towards leather wallet 2 forward, and its both sides are respectively equipped with spring leaf, and a slice and lower house 5 are close, and another sheet and upper shell 4 are close.Upper shell 4 is provided with leaf spring 6, and is provided with the slideway 8 of 53`.Lower house 5 is provided with extension spring 7.

Use operating process of the present utility model: scalp clip 2 and projectile 3 are packed into from the afterbody square hole of clamp in the scalp grip box 1 successively.Grip pincers with holding, groove 10 from scalp clip box 1 enters the slideway 8 of 53 ° of upper shells, under the effect of slideway 8, pusher head leather wallet box 1 moves to the afterbody of clamp, arrive spacing after, open openhanded, under the effect of leaf spring 6 and extension spring 7, last lower house 4,5 and scalp grip box 1 set back.This moment scalp clip 2 the position bunchiness shape that in scalp grip box 1, overlaps as shown in Figure 2.Slightly firmly hold clamp again, can clamp scalp.When the scalp clip box when move at the rear of clamp, it springs in its small square hole near reeds of lower house 5 one sides, and scalp clip 2 and lower house 5 are remained static, and waits for that the groove 9 of scalp grip box 1 head blocks the boss of scalp clip afterbody.Unclamp clamp, scalp grip box 1 is under the effect of extension spring 7, and when the clamp head moved, the opposite side reed of projectile sprang in the small square hole of scalp grip box, and two are synchronized with the movement, and scalp clip is advanced to gives allocation.

The handling method of scalp clip:

In order to reach the purpose of repeatedly using clamp, the afterbody of lower house on the clamp 5 is opened a square hole 9, will be linked to be and go here and there the scalp clip of shape and in this square hole, one push away and can finish clamping.During unloading clip, from the beginning the available clamp that unloads unloads clip and gets final product in the leather wallet outside.
