Description

Nail type dura mater suspension hanger

Technical Field

The invention relates to a nail type dura mater suspension hanger, and belongs to the field of medical equipment.

Background

Clinically, in the craniotomy of neurosurgery, the dura mater in an operation area is suspended conventionally, and the purpose of suspension is to closely attach the dura mater to the edge of a skull bone window, so that secondary epidural hematoma is prevented from being formed, and a plurality of complications are reduced. However, in the actual operation of the operation, many doctors often face many problems when suspending the dura mater. The conventional way of hanging is to sew one end of the dura mater close to the edge of the window of the bone and the other end of the dura mater close to the edge of the window of the bone, but the periost is weaker, so the suture needle is easy to tear when hanging; or may be suspended at the time, but the suspended site becomes loose when the muscles are reset, resulting in local bleeding. Moreover, the periosteum of the temporal side of the skull is deficient, the periosteum of the part is often replaced by the muscle of the temporal part, and the suture cannot be fixed at all, which brings a lot of difficulties for an operator. In response to these problems, for many years, specialists have devised a number of solutions, for example, drilling holes at the edge of a bone window with a milling cutter or an abrasive drill in the operation to hang sutures, but this method often causes new bleeding while destroying exposed bones, and if the operation is not performed properly, the drill may penetrate into the brain to cause hospital injuries.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides the nail type dura mater suspension hanger which provides a stable fixing point for dura mater suspension on the premise of not damaging any tissue structure, and an operator can randomly select the suspension point according to the requirement of the operator so as to ensure that the dura mater is stably attached to the edge of the bone window.

In order to achieve the purpose, the invention adopts the technical scheme that: a nailed dural suspension hanger includes a hanger body; the hanger main body comprises a nail rod arranged transversely, a round hole in the middle of the nail rod and nail arms arranged on two sides of the nail rod; the lower end of the nail arm is provided with a nail tip with an inward end part; the nail tips on the two sides are oppositely arranged; the middle part of the nail arm is provided with a groove.

Furthermore, the nail rod, the nail arm and the nail tip are integrally connected.

Furthermore, the side surface of the groove is in a shape of an obliquely arranged U; the upper end of the groove, which is in contact connection with the nail arm, is consistent with the nail rod in direction, and the end line of the lower end is a certain angle protruding upwards in the middle.

Furthermore, the nail points on the two sides are oppositely arranged, the bottoms of the nail points are horizontal, and cambered surfaces are arranged at the joints of the two sides of the bottoms and the nail arms.

Furthermore, a cambered surface with a certain angle is arranged at the joint between the nail rod and the nail arm; the connecting angle between the nail rod and the nail arm is 105 degrees.

Furthermore, the whole body is made of titanium.

Furthermore, a round hole is designed in the middle of the nail rod for a suture to pass through.

The invention has the beneficial effects that: the cranial nail is made of nickel-titanium alloy material with good compatibility with human tissues, is corrosion-resistant and has a memory function, and a special process is adopted at the position of the suture line, so that the suture line is not damaged while being firmly fixed, and the long-term stability of fixation is ensured. When in use, the special groove cranial clamp with a proper type is matched to provide a convenient operation mode for an operator, and the user can complete the operation process within several seconds for several minutes or even longer.
