Description

Multi-functional bushing type cranium awl

Technical field

This utility model relates to a kind of people's body multifunctional bushing type cranium awl, belongs to clinical treatment apparatus manufacturing technology field.

Background technology

The cranium awl is a kind of medical apparatus and instruments commonly used clinically, is mainly used in through scalp skull taper hole, so that insert conduit in intracranial through the bone hole, and treatment intracranial hemorrhage and other diseases.The at present domestic clinical used cranium awl stainless steel materials that adopt more, cone is round bar shape, and is terminal tapered, because the human body scalp is thicker, elasticity is strong, in the operation after the saturating skull of awl is extracted cranium and is bored, displacement is shunk and not corresponding with the bone hole by scalp ceasma place, makes the bone hole appear unclear, causes and puts the pipe difficulty; Because cone is round bar shape, also be unfavorable for the eliminating of bone bits in the cone simultaneously; The exposure in bone hole is unclear, causes and puts the pipe difficulty; Because cone is round bar shape, also be unfavorable for the eliminating of bone bits in the taper hole simultaneously; The exposure in bone hole is unclear, also influences cleaning and other operations of art open country.

Summary of the invention

Technical problem to be solved in the utility model: design a kind of multi-functional bushing type cranium awl, have functions such as depth localization, chip removal, guiding, auxiliary flushing and electricity coagulate, can be used for the taper hole drainage of ventricular puncture and intracranial hematoma.Solved cranium awl depth localization problem; Chip removal problem in the operation of awl cranium; The bone hole exposes problem and flushing of bone hole and hemostasis problem.

Design of the present utility model: a kind of multi-functional bushing type cranium awl, comprise taper shank (1), stop (2), cone (3) is spiral bit and the front end that is fixed on taper shank (1); In addition, be shaped on external screw thread on the leading section outer wall of taper shank (1), stop (2) is a cavity structure, and its front end is shaped on detent (4), is shaped on female thread on the inwall, and stop (2) spinning is at the leading section of taper shank (1); Taper sleeve pipe (5) is sleeved on the cone (3), and its rear end is shaped on positioning boss (6), is shaped on external screw thread on the outer wall at taper position, and positioning boss (6) is arranged in detent (4).

Advantage of the present utility model and effect:

1, the utlity model has functions such as depth localization, chip removal, guiding, auxiliary flushing and electricity coagulate, can be used for the taper hole drainage of ventricular puncture and intracranial hematoma.

2, this utility model depth localization is accurate, adjusts arbitrarily; Spiral cranium awl helps the bone bits and gets rid of, and reduces intracranial and pollutes, and the taper sleeve pipe enters scalp and skull, and it is clear that the bone hole is exposed, and conduit is inserted smoothly convenient; Through sleeve pipe the bone hole is washed, can be kept the wild cleaning of art; Coagulate dura mater through bone hole electricity, can reduce hemorrhage and help puncture; Need not cut scalp and bore cranium, simple and quick, damage little.

The specific embodiment

A kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.

A kind of multi-functional bushing type cranium awl comprises taper shank (1), stop (2), and cone (3) is spiral bit and the front end that is fixed on taper shank (1); In addition, be shaped on external screw thread on the leading section outer wall of taper shank (1), stop (2) is a cavity structure, and its front end is shaped on detent (4), is shaped on female thread on the inwall, and stop (2) spinning is at the leading section of taper shank (1); Taper sleeve pipe (5) is sleeved on the cone (3), and its rear end is shaped on positioning boss (6), is shaped on external screw thread on the outer wall at taper position, and positioning boss (6) is arranged in detent (4).

Wherein, taper shank: be pole shape metallic object, endcapped, the other end is connected and fixed cone, is shaped on external screw thread in the nearly cone segments of taper shank and is used to connect stop.Cone: select the long steel spiral bit of diameter 5mm for use, end closely is embedded in the taper shank.Stop: be a hollow shape metallic object, two ends are not sealed, and are shaped on female thread in the nearly taper shank end and are used for being connected with taper shank is supporting, are shaped on groove on the cross section of nearly cone segments and are connected with the taper sleeve pipe.Stop rotates on taper shank and relies on the required degree of depth of threaded adjusting cranium awl.The taper sleeve pipe: match for coniform sleeve pipe and with cone, on its taper outer wall, be shaped on external screw thread, after the sleeve pipe tip enters scalp with the cranium awl during operation, the enterprising skull of screw thread; The sleeve pipe rear portion is shaped on projection, and matching with groove on the stop front end face fuses, and can arbitrary combination or decomposition.

Using method: before the art cranium is bored each parts decomposition and be soaked in 75% ethanol (or other sterile pack fluid), assembling is standby only to take out examination after 30 minutes.After being ready to complete before patient's art, measure scalp and the skull thickness of intending the taper hole position according to head CT, tentatively make the required taper hole degree of depth and debug stop, install the taper sleeve pipe (cannula tip is continuous to keep about 2mm distance with the cranium awl is most advanced and sophisticated, be equivalent to approximately this place's skull thickness 1/2); After the local infiltration anesthesia, in drafting the vertical inserting needle of scalp point of puncture, firmly rotate taper shank in the direction of the clock, cranium awl and sleeve pipe promptly slowly enter scalp and skull.When the cranium awl penetrated skull, sleeve pipe was fixed on the lamina externa cranii by the external screw thread on its outer wall, and can slowly take off stop from sleeve pipe this moment, withdrawed from the cranium awl gently, and sleeve pipe is promptly stayed on scalp and the skull, and this moment, the bone hole was high-visible.Whether penetrate (if the not saturating available Kirschner wire of cerebral dura mater scratches gently through collar aperture spy and skull and cerebral dura mater with probe, carry out if operate in operating room, also can after coagulating cerebral dura mater, electrosurgical trocar puncture again), after confirming that skull and cerebral dura mater all penetrate, the latex tubing that can will have the diameter 3mm of nook closing member is sent in the brain to haematoma cavity, take off sleeve pipe after arriving target spot, fixedly drainage tube gets final product in scalp.

Claims

A kind of multi-functional bushing type cranium awl comprises taper shank (1), stop (2), it is characterized in that: cone (3) is spiral bit and the front end that is fixed on taper shank (1).In addition, be shaped on external screw thread on the leading section outer wall of taper shank (1), stop (2) is a cavity structure, and its front end is shaped on detent (4), is shaped on female thread on the inwall, and stop (2) spinning is at the leading section of taper shank (1); Taper sleeve pipe (5) is sleeved on the cone (3), and its rear end is shaped on positioning boss (6), is shaped on external screw thread on the outer wall at taper position, and positioning boss (6) is arranged in detent (4).
