Description
Technical field
The utility model belongs to the field of medical instrument technology, is related to one kind hip arthroscopy simple in structure, easy to use and enters
Road extension fixture.
Background technology
Arthroscope is a kind of rodlike optical instrument of the diameter 4mm or so of observation intra articular structure, is closed for diagnosis and treatment
Save the endoscope of illness.The instrument was promoted and applied since 1970.Arthroscope is filled in the end of a tubule there are one lens,
Tubule is inserted into intra articular, the structure of intra articular will be shown on a monitor.Therefore, pass can be observed directly
Structure inside section.Arthroscope is applied not only to the diagnosis of disease, and is widely used for the treatment of joint disease.Arthroscope hand
Art is a kind of Minimally Invasive Surgery, starts to be mainly used in knee joint, rear sequential use is in hip joint, shoulder joint, ankle-joint, elbow joint
And Minor articulus such as finger etc..When applied to hip joint, due to the tough and tensile plumpness of the capsular ligament of hip joint, when gram with 2mm
After family name's needle is positioned into articular cavity, joint sheath can not enter along the hole that Kirschner wire is beaten, and need with other work
Tool is gradually expanded along the hole that Kirschner wire is squeezed into, and by the bore expansion of 2mm to after a certain size, joint sheath can enter,
To which arthroscope could be placed in into carry out diagnosis and treatment, but since expansion tool at present on the market is complicated, and price is high
It is expensive, therefore the extensive development application of this technology is hindered, for this purpose, developing a kind of expansion simple in structure, cheap
Tool, can be effectively promoted the application of hip arthroscopy technology is necessary.
Utility model content
The purpose of this utility model is to provide a kind of hip arthroscopy approach extension fixtures simple in structure, the operation is stable.
The purpose of this utility model is achieved in that including handle, expanding bar, guide head and pilot hole, the handle
It is arranged in the tail portion of expanding bar, guide head is arranged in the working front edge of the expanding bar, and the setting dextrorotation of 3 outer surface of the guide head is led
To screw thread, the guide head, expanding bar and the axially disposed pilot hole of handle inner.
The utility model combination expanding bar and guide head can carry out size expansion, to meet arthroscope to kirschner pin hole
Joint structure is carried out in the deep enough articular cavity of energy to detect, guide head is set as taper, and right-handed thread, side is arranged on its surface
Just expanding bar is gradually introduced, not only laborsaving, but also reduces the injury to cartilage, the pilot hole of the inside setting of the present apparatus in an axial direction,
When in use, pilot hole is sleeved on Kirschner wire, just can be gradually introduced along Kirschner wire, easy to operate, and guide head and expanding bar are all provided with
It is set to stainless steel, has not only prevented damage of the human liquid substance to device in the course of work, but also damage of the anti-locking apparatus to cartilage.This
Utility model is simple in structure, easy to operate, has very strong practical value in the course of surgery.
Description of the drawings
Fig. 1 is the utility model overall structure diagram；
In figure：1- handles, 2- expanding bars, 3- guide heads, 4- pilot holes.
Specific implementation mode
The utility model will be further described below with reference to the accompanying drawings, but must not add in any way to the utility model
With limitation the scope of protection of the utility model is belonged to based on any changes and modifications made by the utility model introduction.
As shown in Figure 1, the utility model includes handle 1, expanding bar 2, guide head 3 and pilot hole 4, the handle 1 is arranged
In the tail portion of expanding bar 2, the working front edge of the expanding bar 2 is arranged guide head 3, in the guide head 3, expanding bar 2 and handle 1
The axially disposed pilot hole in portion 4.
The guide head 3 is set as conical head, and the small end outer diameter of conical head is set as 2mm, and big end outer diameter is set as 4 ~
5mm。
The taper of the guide head 3 is set as 1：0.5~1.
The diameter of the pilot hole 4 is set as >=2mm.
Dextrorotation guide thread is arranged in 3 outer surface of the guide head.
The guide head 3 is set as stainless steel guide head.
The expanding bar 2 is set as stainless steel expanding bar.
The handle 1 is set as plastic handle, axially disposed anti-slip tank on the handle 1.
Utility model works principle and the course of work：
The utility model structure setting be include expanding bar and guide head, size expansion can be carried out to kirschner pin hole, with
Meet progress joint structure in the deep enough articular cavity of arthroscope energy to detect, guide head is set as taper, and on its surface is arranged
Right-handed thread facilitates being gradually introduced for expanding bar, not only laborsaving, but also reduces the injury to cartilage, and the inside of the present apparatus is arranged along axis
To pilot hole, when in use, pilot hole is sleeved on Kirschner wire, just can be gradually introduced along Kirschner wire, easy to operate, guide head and
Expanding bar, which is all provided with, is set to stainless steel, has not only prevented damage of the human liquid substance to device in the course of work, but also anti-locking apparatus to soft
The damage of bone.The utility model is simple in structure, easy to operate, has very strong practical value in the course of surgery.
It when work, after carrying out hip joint localised puncture with Kirschner wire, is gradually introduced, is expanded along Kirschner wire using this tool
Kirschner pin hole extracts the present apparatus, is placed in joint sheath, arthroscope is put into, to be smoothed out follow-up arthroscopic procedures.
