Description

A kind of manual craniotomy drill
Technical field
The invention belongs to medical instruments field, more particularly to a kind of manual craniotomy drill.
Background technology
The Chinese invention patent of Patent No. 201520672450.5 discloses a kind of manual craniotomy drill external member, above-mentioned hand Dynamic craniotomy drill external member is made when opening cranium, manual craniotomy drill external member will not be skidded with respect to skull and energy due to the presence of pilot pin One man operation, but when drilling skull just, pilot pin may be pierced to encephalic, destroy internal brain tissue.
The content of the invention
The technical problems to be solved by the invention are：In view of the deficienciess of the prior art, provide a kind of simple in construction, energy It is enough easily to be punched on skull, and bored skull block is taken out, avoid too deep pierce inside skull.
To realize the purpose of the present invention, it 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；Manhole is offered on the positioning seat；Described positioning seat lower end is formed along institute State circumferentially equally distributed four pilot pins of through hole；The drilling pipe includes the drilling pipe portion of cylinder, is molded in the drilling pipe portion The knob for piercing distance adjustment and being molded over drilling pipe portion upper end at end；Described drilling pipe subordinate end forms brill Tooth；The described distance adjustment side wall upper part that pierces forms external screw thread；Described adjusting nut part includes and the outer spiral shell The nut of line threaded connection；Described nut inner wall forms internal 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 with the connecting rod Spring；Upper end offers the perforation coordinated with the connecting rod among described knob；Described positioning seat, drilling pipe, adjust spiral shell Parent part and fixed needle assemblies are respectively adopted stainless steel and are integrally formed.
Preferably：Described positioning seat outer wall forms two symmetrical handle portions.
Preferably：The described distance adjustment lower sidewall that pierces offers multiple necks；Described neck 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 inner side are connected with the elastic chuck with the cooperation of described neck, and described neck secures with elastic chuck Position of the adjusting nut part with respect to drilling pipe.
Preferably：Upper end offers the recess coordinated with the handle among described knob, avoids turning Drilling pipe is driven to rotate together during dynamic handle.
Compared with prior art, the beneficial effects of the invention are as follows：In use, first according to actual conditions, by adjusting nut Part is threaded in the correct position for piercing distance adjustment outer wall, and positioning seat then is fixed on into skull position to be punctured, will Drilling pipe after regulation is plugged in the through hole of positioning hole, by fixed pin modular connector in the perforation of drilling pipe；Pinch positioning on the other hand The handle portion in hole, is rotated down handle on the other hand, taper bit is entered skull appropriate depth, is integrally glided in fixed needle assemblies When, spring contraction；Now doctor pinches the handle portion of positioning hole on the other hand, proficiency turn knob portion, due to spring contraction, will bore tooth It is against on skull, when turn knob portion, bores tooth as drilling pipe rotates while moving down, when outside adjusting nut part When projection and the positioning seat of wall offset, it is meant that skull is just drilled to be opened, 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, now because spring extends, by the skull block on taper bit, position So as to being removed inside drilling pipe.

Embodiment
The embodiment of the present invention is made a detailed explanation below according to accompanying drawing.
According to Fig. 1 to Fig. 3, a kind of manual craniotomy drill described in the present embodiment, include positioning seat 1, be plugged on institute The drilling pipe 2 in positioning seat is stated, is threaded in the adjusting nut part 3 of the drilling pipe outer wall, and is slidably connected at the drilling pipe Interior fixation needle assemblies 4；Manhole 13 is offered on the positioning seat；Described positioning seat lower end is formed along the through hole Circumferential equally distributed four pilot pins 12；The drilling pipe includes the drilling pipe portion 21 of cylinder, is molded over drilling pipe portion upper end The knob 23 for piercing distance adjustment 22 and being molded over drilling pipe portion upper end；Described drilling pipe subordinate end forms brill Tooth 20；The described distance adjustment side wall upper part that pierces forms external screw thread 222；Described adjusting nut part include with it is described The nut 32 of external screw thread threaded connection；Described nut inner wall forms internal 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 with the connecting rod and handle The spring 5 that hand is fixedly connected；Upper end offers the perforation 232 coordinated with the connecting rod among described knob；Described Positioning seat outer wall forms two symmetrical handle portions 11；The described distance adjustment lower sidewall that pierces offers multiple necks 221；Described neck 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 the cooperation of described neck is connected with the inside of the clamp ring；Described card Collar inwall relative resilient dop position forms the cavity for accommodating elastic chuck；Described neck secures tune with elastic chuck Save position of the nut piece with respect to drilling pipe；Upper end offers the recess 231 coordinated with the handle among described knob, avoids Drilling pipe is driven to rotate together in swing handle.The part that the elastic chuck is located in cavity is foamed plastic, elastic chuck Outer end is rigid plastics.
In use, first according to actual conditions, adjusting nut part is threaded in and pierces the suitable of distance adjustment outer wall Position, positioning seat is then fixed on skull position to be punctured, the drilling pipe after regulation is plugged in the through hole of positioning hole, will be solid Determine needle assemblies to be plugged in the perforation of drilling pipe；The handle portion of positioning hole is pinched on the other hand, is rotated down handle on the other hand, is made taper bit Into skull appropriate depth, when fixed needle assemblies integrally glide, spring contraction；Now doctor pinches the handle of positioning hole on the other hand Portion, proficiency turn knob portion, due to spring contraction, tooth will be bored and be against on skull, when turn knob portion, bore tooth with brill Cylinder rotate while move down, when the raised and positioning seat of adjusting nut part outer wall offsets, it is meant that skull quilt just Brill is opened, because taper bit is fixed on the skull block after being drilled, so only the manual craniotomy drill external member need to be removed, now by Extended in spring, by the skull block on taper bit, so as to being removed inside drilling pipe.
