Intracerebral hematoma puncture guide apparatus capable of providing precise positioning

Abstract

The invention discloses an intracerebral hematoma puncture guide apparatus capable of providing precise positioning and relates to the field of medical instruments. The apparatus can adapt to different head sizes by adjuring relative distances between threaded holes in a single-fork slide rule and a double-fork base; the apparatus is reliably and fixedly connected to the head of a patient through tips of bone pegs being directly abutted to the head bone layer; puncture points and positioning points are spatially positionally adjusted through the combination of vertical side-to-side translation of a cross slider component in a spatial positioning device and rotational motion of a spherical hinge component, and it is ensured that the positioning points and the puncture points cover all surgical area for intracerebral hematoma puncture; collinear structural restraint of the positioning points and puncture points is maintained through the coaxial coplanar relationship of a guide tube seat component and a positioning seat component; through the guiding function of a guide tube seat, it is ensured that a puncture path is extended along two-point lines of the positioning points and puncture points; therefore, the apparatus provided by the embodiment of the invention can ensure surgical precision.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intracerebral hematoma puncture guide that can realize precise positioning. Background technique [0002] Hypertensive cerebral hemorrhage has become a common and frequently-occurring disease. The disease has three high characteristics of high morbidity, high mortality and high disability. In the past, in the clinical treatment of hypertensive cerebral hemorrhage, conventional bone flap craniotomy was often used to incise the cerebral cortex in a large range, causing damage to important nerve structures in the brain to varying degrees. Invasive surgical method, that is, intracerebral hematoma puncture, is to puncture one or two drainage tubes from outside the brain into the hematoma cavity in the brain to drain the intracerebral hematoma. This method is especially suitable for deep hematomas with a bleeding volume of about 20 ml. However, the hematoma compresses important nerv...

Problems solved by technology

Clinically, it is difficult to achieve the above-mentioned goals by relying on experience alone to puncture with bare hands.

Stereotaxic apparatus can achieve this goal, but its operation steps are cumbersome, and the price of 100 to 2 million makes many hospitals discouraged, especially not suitable for the development of precision surgical treatment of cerebral hemorrhage in grass-roots hospitals
