Description

Multi-angle knee joint dipperstick under arthroscope

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a multi-angle knee joint measuring ruler under an arthroscope.

Background

The arthroscope operation is a minimally invasive operation, has two functions of diagnosis and treatment, inserts an arthroscope with the diameter of about 5mm into a joint cavity through a small incision, enlarges the internal structure of the joint cavity on a monitor, observes pathological changes and positions in the joint cavity, and simultaneously comprehensively inspects and cleans the pathological changes and positions under the monitoring of a display screen.

The operation under the mirror is required to be observed and measured all the time in the arthroscopic surgery process, but the scope of the measurement under the mirror is limited due to the fact that the arthroscope is inconvenient to operate due to small wounds. The existing under-mirror measuring scales are all 90-degree angles, the measuring heads are 5mm, no scale is provided, the under-mirror measuring scales can be estimated only by naked eyes, the requirements of complex structures in joints cannot be met, and the size and the length are not suitable for the body structures of people.

Disclosure of Invention

The utility model aims to solve the defects in the prior art, and provides the arthroscope multi-angle knee joint measuring ruler which is convenient to use and is beneficial to measuring the size of an intra-articular structure under an arthroscope.

In order to achieve the above purpose, the technical scheme adopted is as follows:

the utility model provides a multi-angle knee joint dipperstick under arthroscope, includes handle, extension rod and measurement head, the handle is connected with the extension rod, extension rod and measurement head integrated into one piece, the angle scope between the two is 0 ~ 150, satisfies the various demands of measuring different parts of different structures under the arthroscope, measurement head is provided with 360 hoop scales, compares with the tradition adopts naked eye to estimate, measurement size that can be more accurate.

As another preferable mode of the utility model, the length of the measuring head is 2-6 mm, so that different parts and measuring sizes can be used.

As another preferable aspect of the present utility model, the angle between the extension rod and the measurement head is one of 0 °, 15 °, 30 °,45 °, 60 °, 75 °,90 °,120 °, 150 °.

As another preferable scheme of the utility model, the handle is provided with an angle mark for marking the angle between the extension rod and the measuring head, so that different angle measuring scales can be conveniently selected.

As another preferable scheme of the utility model, the front end of the extension rod is provided with an auxiliary circumferential scale of 360 degrees, so that the depth of a measuring part can be measured in an auxiliary manner.

Compared with the prior art, the arthroscope multi-angle knee joint measuring ruler provided by the utility model is convenient to use, adopts multi-angle design, accords with national knee joint anatomy and structural characteristics, is beneficial to arthroscope measurement of the size of an intra-articular structure, optimizes an operation scheme and provides a beneficial basis for postoperative personalized rehabilitation.

Detailed Description

For a better understanding of the present utility model, specific embodiments of the utility model are described in further detail below with reference to the drawings.

As shown in fig. 1-5, the multi-angle knee joint measuring ruler under the arthroscope comprises a handle 1, an extension rod 2 and a measuring head 3, wherein the handle 1 is connected with the extension rod 2, and the handle 1 is provided with an angle mark for marking between the extension rod 2 and the measuring head 3; the extension rod 2 and the measuring head 3 are integrally formed, the angle ranges between the extension rod 2 and the measuring head 3 are respectively 0 degree, 45 degrees, 90 degrees and 120 degrees, the extension rod accords with the anatomy and structural characteristics of the knee joint of the national man, and the front end of the extension rod 2 is provided with an auxiliary circumferential scale 21 of 360 degrees; the measuring head 3 has a length of 5mm and is provided with a 360 ° circumferential scale 31.

When the measuring instrument is used, a measuring ruler with a proper angle is selected according to the structure and the size of a measuring position under an arthroscope, the measuring head 3 is more accurately measured to be deep and attached to a measuring position, and the size is read according to the circumferential scale 31 on the measuring head 3; at the same time, the auxiliary circumferential graduations 21 on the extension rod 2 can also read the depth of the measuring position. Through the multi-angle design between extension rod 2 and the measurement head 3, can satisfy the demand of measuring different positions in the joint, make put convenient laminating measurement position, it is more accurate to measure.

The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
