Abstract

The utility model belongs to the field of medical instruments, and particularly relates to a medical minimally invasive osteotome which comprises a handle, wherein an osteotome is installed at one end of the handle, a cutting edge is arranged at one end, away from the handle, of the osteotome, the cutting edge is flat, two ends of the cutting edge are arranged in an obtuse angle mode, an osteotome end handle is fixedly installed at one end, away from the osteotome, of the handle, and the flat end is arranged at one end, away from the handle, of the osteotome end handle. The utility model relates to a special osteotome for minimally invasive surgery, which can be used for minimally invasive surgeries of bones and cartilages in orthopedics, neurosurgery, otorhinolaryngology, stomatology and the like, is convenient to hold by hands, and is convenient to exert force when holding a pen type operation, meanwhile, the osteotomy is convenient to exert force to cut into sclerotin, hammering is convenient when necessary, and the purpose of minimally invasive surgery can be achieved by lighter hammering force.

Description

Medical minimally invasive osteotome

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a medical minimally invasive osteotome.

Background

Modern surgical operations have become progressively minimally invasive and precise, with operative wounds and procedures involving increasingly smaller sites, in which operations involving some local, minimal bone removal are involved. The existing osteotome has a wider cutting edge, the handle is square, and the osteotome is required to be matched with a bone hammer for knocking, so that an instrument which can carry out accurate bone repair by only depending on finger force and wrist force is clinically needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides a medical minimally invasive osteotome.

In order to achieve the purpose, the utility model adopts the following technical scheme:

medical wicresoft osteotome, including the handle, the osteotome is installed to the one end of handle, and the one end that the handle was kept away from to the osteotome is provided with the blade, and the blade is the flat mouthful, and the both ends of blade are the obtuse angle setting, the one end fixed mounting that the osteotome was kept away from to the handle has osteotome end handle, the one end that the handle was kept away from to osteotome end handle is the flat mouthful setting.

Preferably, the osteotome is fixedly provided with an end block, one side of the end block, which is close to the handle, is provided with a thread groove, one end of the handle, which is far away from the handle of the osteotome, is provided with an external thread, and the handle thread is arranged in the thread groove.

Preferably, the handle is sleeved with bakelite.

The medical minimally invasive osteotome is a special osteotome for minimally invasive surgery, can be used for minimally invasive surgeries of bones and cartilages, such as orthopedics, neurosurgery, otorhinolaryngology, stomatology and the like, is convenient to hold by hand, and is convenient to apply force when a pen is held for operation, and simultaneously, the medical minimally invasive osteotome is convenient to forcibly cut into bone, is convenient to hammer when necessary, and can achieve the purpose of minimally invasive surgery by using light hammering force.

Drawings

Fig. 1 is a schematic structural view of a medical minimally invasive osteotome according to the present invention;

fig. 2 is a schematic cross-sectional structure view of a handle of the medical minimally invasive osteotome provided by the utility model.

In the figure: 1 handle, 2 osteotomes, 21 cutting edges and 3 osteotome end handles.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, medical minimally invasive osteotome includes handle 1, and the cross-section of handle 1 is hexagonal structure, and osteotome 2 is installed to the one end of handle 1, and the one end that osteotome 2 kept away from handle 1 is provided with blade 21, and blade 21 is the flat mouth, and the both ends of blade 21 are the obtuse angle setting, and the one end fixed mounting that handle 1 kept away from osteotome 2 has osteotome end handle 3, and the one end that handle 1 was kept away from to osteotome end handle 3 is the flat mouth setting.

In the utility model, an end block is fixedly arranged on a osteotome 2, a thread groove is formed in one side of the end block close to a handle 1, an external thread is arranged at one end of the handle 1 far away from an osteotome end handle 3, and the handle 1 is arranged in the thread groove in a threaded manner.

In the utility model, bakelite is sleeved on the handle 1.

In the utility model, the handle 1 is a hexagonal section, bakelite is arranged on the surface of the handle, the handle is convenient to hold by hands, force is applied when a pen is held for operation, the cutting edge 21 is a flat opening, two ends of the cutting edge are sharp corners, the bone can be cut into sclerotin conveniently, the end handle 3 of the osteotome is a flat opening, hammering is convenient when necessary, and the minimally invasive purpose can be achieved by light hammering force due to the narrow cutting edge.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
