4. DESCRIPTION.

Technical field of invention:

The present invention in general relates to surgical tool and more particular relates to medial osteotomy forceps for the surgical operation of nose.

Prior art:

The Rhinoplasty done by breaking the middle part of the nasal bone is generally called as medial Osteotomy of the nose. For this osteotomy in India, a chisel and hammer is used. During the Osteotomy, the surgeon inserts the chisel into subject’s nose, positions it and hits the chisel with the hammer to break the nasal bone.

The current practice is not very user-friendly and comfortable for surgeons. The surgery is often conducted internally with little or complete obstruction of view during operation. There is excessive tissue damage due to crude nature of operation, leading to post operation trauma and internal swelling, in a biological reaction process known as oedema. The fracture line is very unclean, with abrupt cracks all along because of impact and rubbing action of surgical tools.

However, while performing surgery a surgeon faces various problems like limited space, post-operation bleeding and abrupt fracture line. There is a lack of confidence among many ENT surgeons who hesitate from performing the surgery. This forceps will help in performing the surgery effectively giving clean cut and less impact on nose tissues.

Therefore many invention are made to design an efficient surgical tool are as discussed below.

US RE38268 discloses rhinoplasty instruments. Instruments including a pair of scissors for removing the bump from an aquiline nose, wherein the scissors have cutting blades, with mutually facing concave cutting edges matching the shape of the bump, as well as a clamp with two cutting blades each having a double curvature in two perpendicular planes so that the clamp fits the lateral bones of the nose. The clamp enables lateral osteotomy of the nose once the bump has been removed by means of the scissors, whereby the surgeon can reconstruct the shape and profile of the nose. The number of instruments needed may thus be reduced considerably relative to the prior art, while the reliability, accuracy and safety of the operation may be substantially enhanced.

JPH10137253A Osteotomy Saw Guiding Tool. A fixing member to be fixed to the bone is provided with a forward/backward moving member who is freely movably back and forth. A ball screw is provided while being supported at the rear end part of the fixing member and screwed at the rear end part of the forward/backward moving member. A scale is provided for confirming the forward/backward moving amount of the forward/backward moving member to the fixing member. At the top end of the forward/backward moving member, a osteotomy saw guiding plane is provided. The osteotomy saw guiding plane is a flat face along the cutting direction of bone to which the fixing member is fixed, when the forward/backward moving member is moved forward, the osteotomy saw is guided to a bone cutting position and when the forward/ backward moving member is moved back, the osteotomy saw is guided along a bone expecting position.

US 20120130384 A1 discloses Apparatus for Osteotomy and Graft Preparation. Surgical tools that increase surgical accuracy for orthopedic procedures involving long bone osteotomy with or without supplementation with allograft or auto graft. Two clamps on the operative side are rigidly interconnected to one another with an adjustable rod that is locked into place, preserving length and rotation of the bone. A graft preparation device is used on the operative table. It enables alignment of the graft to preserve the desired mechanical and anatomic axes and to provide rigid fixation of the graft for cutting. Adjustable jigs ensure exact cuts.

US 20080294170 A1 discloses self-supporting osteotomy guide and retraction device and method of use. An improved osteotomy guide and retraction device for use during the performance of bunionectomies, whereby the improved device provides a self-supporting instrument that does not require independent fastening means to secure the device in the desired position at the surgical site, and a method of use of the device.

Although the existing method has some drawbacks as-
• Non uniform cutting of nasal bone
• Probability of damaging eyes and brain
• Only an expert hand can do the job
• The surgery is very traumatic

Thus to overcome the drawbacks of the conventional technique there is need to design and develop an efficient tool for the surgery of nose. Hence the present invention designs medial osteotomy forceps for the nose surgery which will ease the operation by reducing surgeon’s efforts and reduction in time giving clean and smooth cut.

Object:

1. Primary object of the present invention is to provide medial osteotomy forceps for the surgical operation of nose.

2. Another object of the present invention is to design the forceps which facilitates ease in performing medial osteotomy as class 1 lever.
3. Yet another object of the present invention is to design a surgical tool that facilitates to cut the nasal bone efficiently.

Other objects, features and advantages will become apparent from detail description and appended claims to those skilled in art.

STATEMENT:

Accordingly following invention relates to a medial osteotomy forceps for the nose surgery which facilitates to cut the nasal bone efficiently. The forceps is an assembly of two pieces with a joint. The curvature of the blade is designed to facilitate easier flow of tip of the forceps while performing surgery. The length of the blade is selected such that required force is enough for cutting. The forceps have very smooth edges so as to help in having proper handgrip. The material used is medical grade Stainless steel. Heat treatment is given to make it hard and durable. Blade of the forceps is to be cladded with surgical grade Tungsten Carbide to ensure smooth edges throughout its life.

BRIEF DESCRIPTION OF DRAWING:
This invention is described by way of example with reference to the following drawing where,

Figure 1 of sheet 1 shows assembled view of nasal bone cutting forceps.
Where,
A denotes right hand side of blade,
B denotes left hand side of blade,
C denotes screw joint,
D denotes blades of forceps.

In order that the manner in which the above-cited and other advantages and objects of the invention are obtained, a more particular description of the invention briefly described above will be referred, which are illustrated in the appended drawing. Understanding that these drawing depict only typical embodiment of the invention and therefore not to be considered limiting on its scope, the invention will be described with additional specificity and details through the use of the accompanying drawing.

Detailed description:

The present invention relates to a design and development of a surgical instrument for doing the medial osteotomy. The main aim of the invention is to develop an instrument to overcome the limitations of existing method and provide comfort to surgeon.

The design process of the proposed invention is initiated by studying the basic lever 1 mechanism, i.e. scissor. The blade is designed so as to fit correctly within the limited space. Shape of the front part of the blade has been so selected such that it occupies minimum space.

The material used is medical grade Stainless steel. Heat treatment is given to make it hard and durable. Blade of the forceps is to be cladded with surgical grade Tungsten Carbide to ensure smooth edges throughout its life.

The surgeon is required to give entry to the forceps from above the skin of the nose. The cutting would be such that it would cut 1 to 2mm of the nasal bone step by step till the forehead is reached in one go.

The forceps is an assembly of two pieces with a joint. The curvature of the blade is designed to facilitate easier flow of tip of the forceps while performing surgery. The length of the blade is selected such that required force is enough for cutting. The forceps have very smooth edges so as to help in having proper handgrip. Use of forceps will reduce extra efforts and frustration a surgeon gets while operating. Also with the use of forceps, the surgery time will be reduced.

As shown in figure 1 of sheet 1, the forceps contain right hand side (A) and left hand side (B) of the blade. A screw joint (C) is used to hold both levers of forceps. The blades of forceps (D) coated with surgical grade of Tungsten carbide.

Additional advantages and modification will readily occur to those skilled in art. Therefore, the invention in its broader aspect is not limited to specific details and representative embodiments shown and described herein. Accordingly various modifications may be made without departing from the spirit or scope of the general invention concept as defined by the appended claims and their equivalents.
