Abstract

The invention discloses a medical bone 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, far away from the handle, of the osteotome, the cutting edge is a flat opening, two ends of the cutting edge are arranged in a sharp angle mode, an osteotome end handle is fixedly installed at one end, far away from the osteotome, of the handle, and the flat opening is arranged at one end, far away from the handle, of the osteotome end handle. The invention relates to a special osteotome for minimally invasive surgery, which can be used for bone and cartilage minimally invasive surgery and medical teaching in orthopedics, neurosurgery, otorhinolaryngology, stomatology and the like, is convenient to hold by hand, and is convenient to exert force when holding a pen type operation, and simultaneously, the bone can be conveniently and forcefully cut into bone, hammering can be conveniently carried out when necessary, and the purpose of minimally invasive surgery can be achieved by lighter hammering force.

Description

Medical sclerotin minimally invasive osteotome

Technical Field

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

Background

The osteotome is often needed in the orthopedic surgery, the integrated osteotome used clinically at present can use a plurality of osteotomes when a complex surgery is performed, inconvenience is brought to the preparation work of the surgery, and infection risks can be increased when doctors frequently replace the osteotome. Some integrated osteotomes with larger or profiled blades cannot pass through the endoscope channel during minimally invasive orthopedic surgery. It is impossible to perform such a task as imaging and treating osteophytes and calcified portions of the nerve root head. But also can not exert force well and slip easily when in use, and the orthopedic surgery often needs larger force to achieve the surgery effect.

The osteotome works by using a hammer to strike the tail to generate force to chisel the bone. Bones with different parts and shapes of an osteotome handle and an osteotome cutter separated type osteotome used clinically require different shapes and specifications of the osteotome cutter, and the osteotome cutter must be frequently replaced. And the osteotome handle and the osteotome cutter separated osteotome are connected through screw threads, and the screw threads are easy to deform under the knocking of a hammer, so that the connection between the handle and the osteotome cutter is easy to lose efficacy. A split-type, under-the-mirror osteotome such as CN201410213683.9 does not allow for bit replacement. The CN201410287439.7 osteotome special for the sagittal split osteotomy of the mandible cannot adapt to the orthopedic shaping in different scenes. CN10396355A "a split type endoscopic osteotome" technical solution it is only suitable for endoscopic operation.

Furthermore, the cutting edge of the osteotome in the prior art is wide, and the osteotome must be used together with the osteotome during the use process, so that the risk of osteotomy, etc. may occur during the operation, therefore, a clinical need exists for a medical osteotome which can precisely repair the bone by means of the finger force and wrist force of medical personnel.

Disclosure of Invention

The invention aims to provide a medical bone minimally invasive osteotome, which aims to solve the problems that the osteotome in the prior art needs to be matched with an osteotome when in use and the osteotome is applicable to different occasions.

In order to achieve the above purpose, the invention provides the following technical scheme:

the utility model provides a medical sclerotin wicresoft osteotome, includes the handle, handle left side and osteotome fixed connection, handle right side and osteotome end handle fixed connection, one side that the handle was kept away from to the osteotome is provided with the blade, the blade is the parallel cut, and both ends are the closed angle, one side that the handle was kept away from to osteotome end handle is the parallel cut.

Preferably, the cross section of the handle is in a hexagonal structure.

Preferably, the handle left side is provided with the external screw thread, fixed mounting has the installation piece on the osteotome, and one side that the installation piece is close to the handle is provided with the thread groove, the handle screw thread is installed in the thread groove.

Preferably, the handle is sleeved with an anti-slip rubber sleeve.

Compared with the prior art, the invention has the beneficial effects that:

according to the medical minimally invasive osteotome, the osteotome is mounted on the left side of the handle, and the osteotome is provided with the flat cutting edge with the sharp corners at two ends, so that medical personnel can cut into bone flexibly in the operation process; the bone groove end handle is fixedly arranged on the right side of the handle, so that when the minimally invasive purpose is achieved by slight force due to the thin and narrow cutting edge, the bone groove end handle can be knocked by the light force; the handle is sleeved with the anti-slip rubber sleeve, so that the medical care personnel can hold the handle conveniently, the force is applied conveniently, and the handle is not easy to slide.

Drawings

Fig. 1 is a schematic structural view of a medical bone minimally invasive osteotome provided by the invention;

fig. 2 is a schematic structural view of a cross section of a handle of the medical bone minimally invasive osteotome provided by the invention.

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.

The first embodiment is as follows: the invention relates to a medical bone minimally invasive osteotome

Referring to fig. 1-2, a medical bone minimally invasive osteotome comprises a handle 1 with a hexagonal section and a surface sleeved with an anti-slip rubber sleeve, which is convenient for medical care personnel to hold, and is hard to slide when holding a pen type operation; the left side of the handle 1 is provided with external threads, the osteotome 2 is fixedly provided with an installation block, one side of the installation block close to the handle 1 is provided with a thread groove, the handle 1 is installed in the thread groove in a threaded manner, one side of the osteotome 2 far away from the handle 1 is provided with a cutting edge 21, the cutting edge 21 is a flat mouth, and two ends are sharp corners, so that medical personnel can flexibly cut into an estimated value in the operation process; the right side of the handle 1 is fixedly connected with the osteotome end handle 3, and one side of the osteotome end handle 3, which is far away from the handle 1, is a flat opening, so that the osteotome end handle can be conveniently knocked by light force when the minimally invasive purpose is achieved by light force due to the thin and narrow cutting edge 21.

Example two: clinical application experiment of medical bone minimally invasive osteotome

Doctors using the osteotome of the application and the osteotome with the replaceable head in the prior art twice in a certain hospital in Shaanxi obtain the evaluation description of the doctors on the products.

Through use, doctors think that the osteotome has a simple structure, the disassembly and disinfection time can be shortened by 5-10min, and the osteotome is smooth in use, does not slide off and can flexibly cut into sclerotin; and the right side of the handle is fixedly provided with the bone groove end handle, so that the bone groove end handle can be conveniently knocked by light force when the minimally invasive purpose is achieved by light force due to the thin and narrow cutting edge.
