Abstract

The present invention, relating to the field of medical treatment, discloses a cranial clamp wherein the upper clamp head is in a thick and square shape with a round hole at the front end for the purpose of locating the drilling position, and the lower clamp head is in a wide and flat shape. In order to make it convenient to fix the drilling position, the round hole needs to have a certain depth which is the thickness of the upper clamp head, so the upper clamp head is made to be thick and square to better stabilize the position of drilling, which is convenient for the operations of the medical staff. On the other hand, the lower clamp head is mainly used to coordinate with the upper clamp head to clinch the skull, so by designing it in the wide and flat shape, the possibility of injuries to the brain tissue in the vicinity of the skull can be reduced to the lowest extent, and when a drilling head is passing through the skull, it can effectively withstand the drill head to protect the brain tissues under the skull.

In neurosurgery, the greatly ratio that occupied craniocerebral operations.In craniocerebral operations, run into situation about need on skull, hole through regular meeting, just need carry out stationary positioned to the position of need boring by cranium brain pincers this moment.

At present, cranium brain pincers commonly used are made up of upper grip head 1, lower pliers head 2, pincers handle 3 and lever 4 as shown in Figure 1.Front end at upper grip head 1 is provided with a circular hole 5, as shown in Figure 2.The concrete operation method of these cranium brain pincers is as follows:

Utilize the skull that upper grip head 1 and lower pliers head 2 vise needs boring, 5 aligned positions of circular hole are the position that need hole.By the screens of pincers tooth, pin the degree of engagement of upper grip head 1 and lower pliers head 2.At this moment, can utilize drill bit to hole in 5 aligned positions of circular hole.

Yet the present inventor finds, the thickness of the lower pliers head 2 of existing cranium brain pincers is with the consistency of thickness of upper grip head 1, but owing to all be cerebral tissue near the skull, if lower pliers head is blocked up, with the unnecessary cerebral tissue that is damaged to.And the pincers tooth 6 of existing cranium brain pincers is also less,, needs to use bigger strength, thereby the skull that is vised has been caused bigger pressure when pinning the degree of engagement of upper grip head 1 and lower pliers head 2 at engaging pincers tooth.

Summary of the invention

The object of the present invention is to provide a kind of cranium brain pincers,, avoid as much as possible near the brain tissue injury the skull using cranium brain pincers fixedly during the bore position of skull.

For solving the problems of the technologies described above, embodiments of the present invention provide a kind of cranium brain pincers, are made up of upper grip head 1, lower pliers head 2, pincers handle 3 and lever 4, and it is thick square that upper grip head 1 is, and is provided with a circular hole 5 at upper grip head 1 front end;

Lower pliers head 2 is wide flat, by with the interlock of upper grip head 1, vise the skull that need hole, the position of circular hole 5 aligned positions for holing;

The drill bit that is used to punch is holed at circular hole 5 places.

Embodiment of the present invention compared with prior art, the main distinction and effect thereof are:

Upper grip head is the thick quadrate while, and lower pliers head is wide flat.Because the position of boring is after vising the skull that need hole, fixed by the circular hole institute that the upper grip head front end is provided with, position for ease of the fixed drill bit punching, need circular hole that certain degree of depth is arranged, and the degree of depth of circular hole is the thickness of upper grip head, therefore upper grip head is set to the thick square position that can fix bit bore preferably, is convenient to medical worker's operation.And lower pliers head mainly is to be used to cooperate upper grip head to vise skull; therefore by lower pliers head being designed to wide flat, can avoid as much as possible near the brain tissue injury the skull, and can be effectively when drill bit drills skull; withstand drill bit, the cerebral tissue under the skull is played a protective role.

Further, the pincers tooth on the pincers handle will be more than the pincers tooth of general cranium brain pincers.Because the pincers tooth of pincers on the handle is the degree of engagement that is used to regulate binding clip, the pincers tooth is many more, regulates with regard to the easy more degree of engagement to binding clip.That is to say that the pincers tooth is many more, when regulating the tightness of cranium brain pincers, just more little to the pressure of skull.Therefore, by the more pincers of design tooth on the pincers handle, can reduce pressure to skull.
