Description

A kind of manual craniotomy drill
Technical field
The invention belongs to medical instruments field more particularly to a kind of manual craniotomy drills.
Background technique
The Chinese invention patent of Patent No. 201520672450.5 discloses a kind of manual craniotomy drill external member, above-mentioned hand Craniotomy drill external member is moved due to the presence of pilot pin, is made when opening cranium, manual craniotomy drill external member will not skid with respect to skull and energy One man operation, but when drilling skull just, pilot pin may be pierced to encephalic, destroy internal brain tissue.
Summary of the invention
The technical problems to be solved by the present invention are: in view of the deficienciess of the prior art, a kind of simple, the energy that provides structure It is enough easily to be punched on skull, and bored skull block is taken out, avoid too deep pierce inside skull.
Purpose to realize the present invention, is achieved using following technical scheme: a kind of manual craniotomy drill, includes positioning Seat, the drilling pipe being plugged in the positioning seat is threaded in the adjusting nut part of the drilling pipe outer wall, and is slidably connected at Fixation needle assemblies in the drilling pipe；Circular through hole is offered on the positioning seat；The positioning seat lower end is formed along institute State circumferentially equally distributed four pilot pins of through-hole；The drilling pipe includes cylindrical drilling pipe portion, is molded in the drilling pipe portion The knob for piercing distance adjustment and being molded over drilling pipe portion upper end at end；The drilling pipe subordinate end forms brill Tooth；The distance adjustment side wall upper part that pierces forms external screw thread；The adjusting nut part includes and the outer spiral shell The nut that line is threadedly coupled；The nut inner wall forms internal screw thread；The fixed needle assemblies include taper bit and Handle；Connecting rod is formed between the taper bit and handle；The bullet being fixedly connected with handle is socketed in the connecting rod Spring；Upper end offers the perforation with connecting rod cooperation among the knob；The positioning seat, drilling pipe adjust spiral shell Stainless steel integrated molding is respectively adopted in parent part and fixed needle assemblies.
As a preferred solution: there are two symmetrical handle portions for the positioning seat outer wall molding.
As a preferred solution: the distance adjustment lower sidewall that pierces offers multiple card slots；The card slot edge Pierce the circumferentially equidistant from distribution of distance adjustment；The nut lower end forms the clamping being plugged in the through-hole of positioning seat Circle, the clamp ring inside are connected with the elastic chuck with card slot cooperation, and the card slot is secured with elastic chuck Position of the adjusting nut part with respect to drilling pipe.
As a preferred solution: upper end offers the recess with handle cooperation among the knob, avoid turning Drilling pipe is driven to rotate together when dynamic handle.
Compared with prior art, the beneficial effects of the present invention are: in use, first according to the actual situation, by adjusting nut Part is threaded in the suitable position for piercing distance adjustment outer wall, and positioning seat is then fixed on skull position to be punctured, will Drilling pipe after adjusting is plugged in the through-hole of location hole, by fixed pin modular connector in the perforation of drilling pipe；Positioning is pinched on the other hand The handle portion in hole, is rotated down handle on the other hand, and taper bit is made to enter skull appropriate depth, integrally glides in fixed needle assemblies When, spring contraction；Doctor pinches the handle portion of location hole on the other hand at this time, and tooth will be bored by rotating knob on the other hand due to spring contraction It is against on skull, when rotating knob, bores tooth as drilling pipe moves down while rotating, when outside adjusting nut part When protrusion and the positioning seat of wall offset, it is meant that skull is drilled open just, and the skull block after being drilled is fixed on due to taper bit On, so only the manual craniotomy drill external member need to be removed, at this time since spring extends, by the skull block on taper bit, position To be removed inside drilling pipe.

Specific embodiment
A specific embodiment of the invention is made a detailed explanation below according to attached drawing.
According to Fig. 1 to Fig. 3, a kind of manual craniotomy drill described in the present embodiment includes positioning seat 1, is plugged on institute The drilling pipe 2 in positioning seat is stated, the adjusting nut part 3 of the drilling pipe outer wall is threaded in, and is slidably connected at the drilling pipe Interior fixation needle assemblies 4；Circular through hole 13 is offered on the positioning seat；The positioning seat lower end is formed along the through-hole Circumferential equally distributed four pilot pins 12；The drilling pipe includes cylindrical drilling pipe portion 21, is molded over drilling pipe portion upper end The knob 23 for piercing distance adjustment 22 and be molded over drilling pipe portion upper end；The drilling pipe subordinate end forms brill Tooth 20；The distance adjustment side wall upper part that pierces forms external screw thread 222；The adjusting nut part include with it is described The nut 32 that external screw thread is threadedly coupled；The nut inner wall forms internal screw thread 321；The fixed needle assemblies include taper Drill bit 41 and handle 43；Connecting rod 42 is formed between the taper bit and handle；It is socketed in the connecting rod and handle The spring 5 that hand is fixedly connected；Upper end offers the perforation 232 with connecting rod cooperation among the knob；Described There are two symmetrical handle portions 11 for the molding of positioning seat outer wall；The distance adjustment lower sidewall that pierces offers multiple card slots 221；The card slot edge pierces the circumferentially equidistant from distribution of distance adjustment；The nut lower end, which forms, is plugged on positioning seat Through-hole in clamp ring 31, the elastic chuck 311 with card slot cooperation is connected on the inside of the clamp ring；The card Collar inner wall relative resilient clamp position forms the cavity for accommodating elastic chuck；The card slot and elastic chuck secures tune Save position of the nut piece with respect to drilling pipe；Upper end offers the recess 231 with handle cooperation among the knob, avoids Drilling pipe is driven to rotate together in swing handle.It is foamed plastic, elastic chuck that the elastic chuck, which is located at the part in cavity, Outer end is rigid plastics.
In use, first according to the actual situation, adjusting nut part being threaded in and pierces the suitable of distance adjustment outer wall Then positioning seat is fixed on skull position to be punctured, the drilling pipe after adjusting is plugged in the through-hole of location hole, will consolidated by position Determine needle assemblies to be plugged in the perforation of drilling pipe；The handle portion for pinching location hole on the other hand, is rotated down handle on the other hand, makes taper bit Into skull appropriate depth, when fixed needle assemblies integrally glide, spring contraction；Doctor pinches the handle of location hole on the other hand at this time Portion rotates knob on the other hand, due to spring contraction, will bore tooth and is against on skull, when rotating knob, bores tooth with brill Cylinder moves down while rotating, when the protrusion of adjusting nut part outer wall offsets with positioning seat, it is meant that skull quilt just Brill is opened, since taper bit is fixed on the skull block after being drilled, so only the manual craniotomy drill external member need to be removed, at this time by It is extended in spring, the skull block on taper bit is removed inside drilling pipe.
