Embodiment Construction

[0008] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] In the accompanying drawings, 1 is a fixing frame, 2 is a fixing nail, 3 is a fixing screw, 4 is a connecting rod, 5 is a positioning frame, 6 is a directional rod, 7 is a cranial drill bit, and 8 is a multidirectional joint.

[0010] Such as figure 1 As shown, the present invention is a special device for intracranial hematoma orientation and cranial drilling, which mainly consists of two parts, a fixing frame 1 and a positioning frame 5, and the fixing frame 1 and the positioning frame 5 are connected at the bottom by a connecting rod 4. The fixed frame 1 is composed of two vertical rods and a horizontal rod to form an arc or U shape corresponding to the human skull, and one of the vertical rods is sleeved on the horizontal rod through a sleeve, so that the vertical rod can move along the horizontal rod to form a movable Type vertical pole to...

Abstract

The invention relates to an intracranial hematoma orientation skull-perforation instrument, belonging to medical appliance, which mainly comprises a fixed bracket with symmetrically fixed nails and screws. The invention is characterized in that the fixed bracket is connected with a positioning bracket which is provided with a positioning rod and a skull-perforation hole. The centre axles of the positioning rod and the skull-perforation hole are located at the same straight line. The skull-perforation hole together with a skull drill and a drainage tube are matched, to be used combined with CT sheet, thereby confirming the position and depth of the intracranial hematoma accurately as well as the puncture point, puncture direction and puncture depth of the perforation skull, with the effects of firm fixation, accurate position, simple operation, simple structure and convenient use.

Description

technical field [0001] The invention belongs to medical instruments, in particular to a directional drilling device for cranial surgery. Background technique [0002] Intracranial puncture has a wide range of applications, and can be used to treat hypertensive cerebral hemorrhage, intracranial hematoma and other diseases. Hematoma location and accurate selection of puncture point, puncture direction, and puncture depth are the keys to the success of puncture surgery. The positioning devices currently used at home and abroad, such as three-dimensional stereotaxic instruments, use the principle of stereotaxic positioning at a certain point, first find a structure with a relatively constant anatomical position in the brain as the origin of positioning, and then design three mutually perpendicular planes through this origin That is, the three-dimensional coordinate system, which measures the three-dimensional coordinate value of the target point in the brain in the three-dimens...
