Description

Cranial-bone-flap reset drill protector

Technical field

This utility model relates to a kind of Cranial-bone-flap reset drill protector, belongs to medical instruments field.

Background technology

In clinical, many Craniotomies Cranial-bone-flap that need reset, now conventional two kinds of ways: a kind of way is by using brace and screw or skull lock (being titanium or absorbable material), Cranial-bone-flap being fixed on to part lack of skull; Another way is in Cranial-bone-flap and the punching of defect of skull area edge, by hole, with suture, both is fixed together.First method need increase thousands of first Master Costs, and immobilization material is foreign body, increases infection chance.Second method just saves medical expense and foreign residues in intracranial, but need to be in Cranial-bone-flap and the punching of defect of skull area edge, and all existence damage patient's cerebral dura mater and cerebral tissue may to use dynamical system to punch.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art; a kind of Cranial-bone-flap reset drill protector is provided; it can avoid apparatus damage patient's cerebral dura mater and cerebral tissue when punching; not only can save medical expense; foreign residues in intracranial, and reduced and infected possibility, and also easy and simple to handle; easily by patient, accepted, clinic is promoted.

In order to solve the problems of the technologies described above; technical solution adopted in the utility model is: a kind of Cranial-bone-flap reset drill protector; it comprises support limit frame and drill jig; the centre of drill jig is provided with the boring matching with drill bit; support limit frame is mainly made into integration by drill jig gripper shoe, side banking stop and bottom surface screening glass; drill jig is fixedly mounted in drill jig gripper shoe, and the both sides of the relative position of holing on the banking stop of side are respectively arranged with side guardrail.

Further, support limit frame left side has handle, and handle is connected with drill jig gripper shoe.

During use, with left hand, arrest handle; the right hand is held dynamical system and through drill hole, on skull, is drilled with and connects bundle inclined hole; bottom surface screening glass reaches the below of skull through the edge in skull operation hole; and side guardrail is close to surgical hole edge; owing to there being the protection of bottom surface screening glass and side guardrail; so just can avoid damaging patient's cerebral dura mater and cerebral tissue when punching, and due to gapped existence between both sides side guardrail and defect of skull edge, during punching, just can make hole connect.Not only can save medical expense, foreign residues in intracranial, and reduced and infected possibility, and also easy and simple to handle, easily by patient, to be accepted, clinic is promoted.

The specific embodiment

For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail below.

As Figure 1-Figure 11; a kind of Cranial-bone-flap reset drill protector; it comprises support limit frame (1) and drill jig (1-3); the centre of drill jig 1-3 is provided with the boring 1-3-1 matching with drill bit 3; support limit frame 1 is mainly made into integration by drill jig gripper shoe 1-5, side banking stop 1-6 and bottom surface screening glass 1-4; it is upper that drill jig 3 is fixedly mounted on drill jig gripper shoe 1-5, and the both sides of the relative position of holing on the banking stop of side are respectively arranged with side guardrail.

As shown in Figure 1, support limit frame 1 left side has handle 1-1, and handle 1-1 is connected with drill jig gripper shoe 1-5.

During use, with left hand, arrest handle 1-1, the right hand is held dynamical system and is on skull 2 and is drilled with and meets bundle inclined hole 2-2 through boring 1-3-1, bottom surface screening glass 1-4 reaches the below of skull 2 through the edge of skull 2 surgical hole 2-1, and side guardrail 1-2 is close to surgical hole 1-2 edge, owing to there being the protection of bottom surface screening glass 1-4 and side guardrail 1-2, so just can avoid damaging patient's cerebral dura mater and cerebral tissue when punching, not only can save medical expense, foreign residues in intracranial, reduced and infected possibility, and easy and simple to handle, easily by patient, accepted, clinic is promoted.

Above-described specific embodiment; technical problem, technical scheme and beneficial effect that this utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
