Abstract

The utility model discloses a bone object is bored to high accuracy, including motor, drill bit, lance pipe, infra -red transmitter, the lance pipe be hollow structure and through the shaft coupling with the output shaft of motor, the rear end cartridge of drill bit is in in the lance pipe and through the nut fastening, the the central axis of drill bit goes up to open there is the through -hole, be equipped with transparent head in the front end through -hole of drill bit, infra -red transmitter installs on the rear end of drill bit, and place in in the lance pipe, be carved with length flag on the drill bit. The utility model discloses a bone object is bored to high accuracy has drilling locate function and bore depth measurement function, and the doctor of being convenient for holds the accurate of the drilling position and drilling depth when boring the bone.

Description

A kind of high-precision drilling bone object

Technical field

This utility model relates to a kind of medical apparatus and instruments, is specifically related to the high-precision drilling bone object of a kind of orthopaedics.

Background technology

In clinical medicine, fracture is common bone wound disease, and it is real for treating fracture most common method Execute internal fixation operation, i.e. with blade plate and steel nail, skeleton is coupled together.When implementing internal fixation just Need to use brill bone object to hole on skeleton with fixing steel nail.

Boring bone object is the medical apparatus and instruments that a kind of orthopaedics is conventional, and existing brill bone object structure is relatively easy, no Possess drilling-hole positioning device and hole depth measurement device, when operation entirely with doctors experience to bore position and Drilling depth is control.Once there is deviation in boring, must carry out boring and repair or secondary drilling, not only Add operating difficulty, also extend operating time, easily cause subjects bones's secondary damage simultaneously, Shortcomings.

Utility model content

For above-mentioned deficiency, this utility model provides a kind of high-precision drilling bone object, has boring location merit Energy and hole depth measure function, it is simple to bore position and the accurate of drilling depth are held by doctor when boring bone.

The technical solution of the utility model is:

A kind of high-precision drilling bone object, including motor, drill bit, drilling pipe, infrared transmitter；Described drilling pipe It is connected for hollow structure and by shaft coupling with the output shaft of described motor；The rear end plug-in mounting of described drill bit Fasten in described drilling pipe and by nut, the central axis of described drill bit has through hole, described brill It is provided with transparent end socket in the front end through hole of head；Described infrared transmitter is arranged on the rear end of described drill bit, It is placed in described drilling pipe；It is carved with length mark on described drill bit.

The utility model has the advantages that: high-precision drilling bone object of the present utility model passes through infrared transmitter pair Bore position positions, the most precisely；By scribing length mark on drill bit, it is simple to intuitively sentence Breaking of rod hole depth；This utility model uses very convenient, and Bone drill hole precision is high, reduces doctor's work Make difficulty, saved operating time, decrease patient suffering.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As it is shown in figure 1, a kind of high-precision drilling bone object, including motor (1), drill bit (2), drilling pipe (3), Infrared transmitter (4)；Described drilling pipe (3) is hollow structure and passes through shaft coupling (5) and described electricity The output shaft of machine (1) connects；The rear end of described drill bit (2) is inserted in described drilling pipe (3) and leads to Cross nut (6) fastening, the central axis of described drill bit (2) has through hole (7), described drill bit (2) transparent end socket (8) it is provided with in front end through hole；Described infrared transmitter (4) is arranged on described On the rear end of drill bit (2), it is placed in described drilling pipe (3)；Described drill bit is carved with length on (2) Labelling (not shown).

The above is preferred implementation of the present utility model, it is noted that for the art Those of ordinary skill for, on the premise of without departing from this utility model principle, it is also possible to if making Dry improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.

Claims

1. a high-precision drilling bone object, it is characterised in that: described brill bone object include motor, drill bit, drilling pipe, Infrared transmitter；Described drilling pipe is hollow structure and is connected with the output shaft of described motor by shaft coupling； The rear end of described drill bit is inserted in described drilling pipe and is fastened by nut, the central axis of described drill bit On have through hole, be provided with transparent end socket in the front end through hole of described drill bit；Described infrared transmitter is installed On the rear end of described drill bit, it is placed in described drilling pipe；It is carved with length mark on described drill bit.
