Abstract
The utility model discloses a manual craniotomy drill with a lighting device and belongs to the technical field of neurosurgery. The manual craniotomy drill comprises a drill rod, a handheld handle and a drill head, wherein the upper end of the drill rod is connected with the handheld handle, and the lower end of the drill rod is connected with the drill head through threads. The manual craniotomy drill is characterized in that a positioning ring with a positioning mechanism is connected at the middle of the drill rod in sleeved mode, a threaded through hole connected into a circle center hole is arranged on the lateral surface of the positioning ring, and the positioning mechanism is screwed into the threaded through hole of the positioning ring. An elbow is further arranged on the positioning ring, and a light emitting diode (LED) lamp is arranged on the elbow. Compared with the prior art, the manual craniotomy drill has the advantages of facilitating mastering of the depth of drilled holes; being slow in drill head rotating speed, generating a little heat and being capable of avoiding human tissue scorching; and being simple in structure, low in cost and convenient to popularize and use.
Description
Technical field
This utility model relates to a kind of drill for craniotomy, particularly a kind of manual drill for craniotomy with illuminator that is applicable to the neurosurgery special use.
Background technology
In the neurosurgery clinical operation, drill for craniotomy is one of the most frequently used instrument, the drill for craniotomy that uses at present comprises manual type, pneumatic type and electrodynamic type, using clinically the most common is that Manual type cranial drill and electrodynamic type cranium bore, but these two kinds of craniums are drilled in and all have many technological deficiencies in use procedure: 1. the electrodynamic type cranium bores that rotating speed is high, the drill bit quick heating, burns that the situation of tissue occurs near even burnt boring so often have; Complicated integral structure, expense are high; 2. there is no spacing or detent mechanism on Manual type cranial drill, the boring depth is difficult for grasping; There is no shoe on hand holding handle, slippage easily occurs in use, thereby cause malpractice; 3. when processing the crisis such as open-air rescue situation, owing to lacking the operating room shadowless lamp, the operation process mesocrany bores the shade that produces can cause interference to the enforcement of operation.
The utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of manual drill for craniotomy with illuminator of neurosurgery special use is provided.
The technical scheme in the invention for solving the technical problem is: comprise drilling rod, hand holding handle, drill bit, described drilling rod upper end connects hand holding handle, drilling rod lower end and is connected with drill bit by screw thread, it is characterized in that: be socketed with the locating ring with detent mechanism in the middle part of described drilling rod, the side of described locating ring has the tapped through hole that leads to circle center hole, and described detent mechanism is screwed in the locating ring tapped through hole; Also be provided with bend pipe on described locating ring, bend pipe is provided with the LED lamp.
Above-mentioned detent mechanism is that front end is opened threaded swing handle.
Above-mentioned drill bit is the Helical Twist Drill head.
Above-mentioned bend pipe is coil.
Overlap rubber sleeve on above-mentioned hand holding handle, described rubber sleeve is provided with a plurality of grooves.
Compared with prior art, the utlity model has following outstanding beneficial effect.
1, the drilling rod middle part is socketed with the locating ring with detent mechanism, can determine out the cranium degree of depth according to testing result when implementing operation, thereby avoid drill bit to injure cerebral tissue, is beneficial to carrying out smoothly of subsequent procedures.
2, also be provided with bend pipe on locating ring, bend pipe is provided with the LED lamp, can regulate the position of LED lamp according to the needs of practical situation, has avoided the operation process mesocrany to bore the shade that produces operation is caused interference.
3, overlap rubber sleeve on hand holding handle, described rubber sleeve is provided with a plurality of grooves, and cranium bores and is not easy slippage from operator's hands, thereby has avoided the generation of malpractice.
4, drill speed is slow, produces heat few, can avoid near the tissue of calcination boring; Simple in structure, with low cost, be convenient to promote and use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1, this utility model comprises drilling rod 1, hand holding handle 2, drill bit 3, and drilling rod 1 upper end connects hand holding handle 2, drilling rod 1 lower end and is connected with drill bit 3 by screw thread.
Described drilling rod 1 middle part is socketed with the locating ring 4 with detent mechanism, the side of described locating ring 4 has the tapped through hole that leads to circle center hole, described detent mechanism is screwed in the locating ring tapped through hole, described detent mechanism is that front end is opened threaded swing handle 5, swing handle 5 front ends are screwed in locating ring 4 side openings, by the unscrewing, screw of swing handle 5, can make locating ring 4 displacements or location.Thereby can determine out the cranium degree of depth according to testing result when implementing operation, thereby avoid drill bit 3 to injure cerebral tissue, be beneficial to carrying out smoothly of subsequent procedures.
Also be provided with bend pipe 6 on described locating ring 4, described bend pipe 6 is coil, and bend pipe 6 is provided with LED lamp 7, can need as the case may be when operation, regulates the position of LED lamp 7, has avoided the operation process mesocrany to bore the shade that produces operation is caused interference.
Comprise also in prioritization scheme that described drill bit 3 is Helical Twist Drill head 3, two spiralling grooves are arranged on described Helical Twist Drill head 3, be convenient to the tissues in small, broken bits such as bone bits that cut away by drill bit 3 up with the groove on spiral bit 3, make the boring on skull salubrious, in order to carrying out smoothly of subsequent procedures.
Cover rubber sleeve 8 on described hand holding handle 2, described rubber sleeve 8 is provided with a plurality of grooves 9, and cranium bores and is not easy slippage from operator's hands, thereby has avoided the generation of malpractice.
Need to prove; particular of the present utility model is described in detail this utility model; for a person skilled in the art, in the situation that do not deviate from various apparent change that spirit and scope of the present utility model carry out it all within protection domain of the present utility model.
