Description

Spacing formula arc osteotome

Technical Field

The utility model relates to an orthopedics apparatus technical field, concretely relates to spacing formula arc osteotome.

Background

A conventional osteotome generally consists of a blade handle and a handle, the distal end of which is sharp and the handle is located at the proximal end. At present, a common osteotome and an arc osteotome are available in the market, the common osteotome is used for conventional osteotomy and bone extraction, and the arc osteotome is used for pelvis osteotomy of hip joint dislocation, and the like; at present, no proper surgical instrument is available for bone extraction of ilium, so that the bone extraction is difficult and the surgical time is long; children patients need blood transfusion frequently, and the risk of infection diseases exists in blood transfusion; the operation time is long, and a plurality of operation complication risks also exist; the knife-edge limitless device of the common osteotome is easy to damage the internal plate of the ilium.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is, overcome the above-mentioned defect that prior art exists, provide one kind and solve the ilium deep and get bone difficulty problem, avoid damaging a spacing formula arc osteotome of ilium inner panel.

The utility model provides a technical scheme that its technical problem adopted is: a limit type arc osteotome is composed of a handle and a firmware which are connected with each other, wherein the upper part of the firmware is provided with a limit block; the handle and the tough body are integrally S-shaped, a tangent plane section is arranged on the upper portion of the tough body, a tough head is arranged on the top of the tangent plane section, limiting blocks are arranged on two sides of the tough head, and a tough opening is formed in the middle of the top end of the tough head.

Furthermore, the tough opening is a V-shaped opening or a flat opening,

furthermore, two sides of the tough opening are tips.

Furthermore, the section of the tangent plane comprises an upper tangent plane and a lower tangent plane, the upper tangent plane is arranged at the inner bending side, the lower tangent plane is arranged at the outer bending side corresponding to the upper tangent plane, and the length of the upper tangent plane is longer than that of the lower tangent plane.

Furthermore, the limiting block is triangular, and one side of the limiting block is perpendicular to two sides of the tough head.

Furthermore, the tough body is connected with the handle through the connecting section, and the bottom of handle is provided with the crown.

Further, the handle is hexagonal prism-shaped.

Furthermore, the tough opening is 5mm in length, 1mm in thickness and 5mm in width, and the limiting block is 11mm in length and 1.7mm in thickness.

Further, the handle length is 83mm, and the firmware length is 125mm, and the diameter is 6 mm.

The beneficial effects of the utility model are that, make things convenient for the ilium deep to get the bone, can shorten operation time, reduce the amount of bleeding when getting the bone. The osteotome is S-shaped, so that the osteotome can conveniently chisel the bottom edge of the external iliac plate, and the tip limiter is unique and can limit the depth of the tough opening entering the bone; does not damage the internal plate of the ilium and the internal organs of the pelvic cavity, and reduces the operation risk.
