Technical Field
The utility model relates to the technical field of electrosurgical instruments, in particular to a spade-type cutter head plasma cutter applied to low-temperature operation.
Background
Numerous operation electrodes of electrosurgery are widely applied to various surgical operations, but a high-efficiency and convenient cutting tool is lacked in major tissue cutting and other professions, the shovel-shaped tool bit technology aims at solving the problem in the field, the original traditional shovel-shaped tool bit is directly bent and processed into a shovel-shaped shape, the tool bit does not have a cutting edge dip angle, the doctor operation is particularly laborious, the cutting efficiency is low, the temperature of the operation cutting is higher due to the fact that the tool bit does not have the cutting edge dip angle and lacks a cutting edge, and the operation feeling of the doctor is poor due to the low cutting efficiency.
Disclosure of Invention
In order to overcome the defects in the background art, the utility model discloses a shovel-shaped cutter head plasma cutter applied to low-temperature operation, which can effectively cut focus parts of patients, improve cutting efficiency, reduce operation time, ensure concentration of current density through a cutter head part on a cutter body, facilitate operation of staff, improve sharpness of the cutter body, facilitate operation of medical staff, avoid drag feeling during cutting, and reduce pain of the patients.
In order to achieve the aim of the utility model, the utility model adopts the following technical scheme:
the utility model provides a be applied to shovel shape tool bit plasma cutting knife of low temperature operation, includes the cutter body, and the one end of cutter body is equipped with the joint hole, the other end of cutter body is the tool bit portion, and the shape of tool bit portion is shovel shape.
The tool bit part consists of a main cutting surface, a main blade, an external cutting surface and an internal cutting surface.
And the intersection part of the main cutting surface and the external cutting surface is a main cutting edge.
The included angle alpha between the main cutting surface and the external cutting surface is 29-33 degrees.
The included angle beta between the external cutting surface and one side of the cutter body, which is positioned on the external cutting surface, is 19-22 degrees.
The included angle theta between the main cutting surface and the cutter body at one side of the inner cutting surface is 8-14 degrees.
Due to the adoption of the technical scheme, the utility model has the following beneficial effects:
the shovel-shaped cutter head plasma cutting knife applied to low-temperature operation can effectively cut focus parts of patients, improves cutting efficiency, reduces operation time, ensures concentration of current density through the cutter head part on the cutter body, facilitates operation of staff, improves sharpness of the cutter body, facilitates operation of medical staff, avoids pulling sense during cutting, and reduces pain of patients.

Detailed Description
The utility model will be explained in more detail by the following examples, the purpose of which is to protect all technical improvements within the scope of the utility model.
The spade-shaped cutter head plasma cutter for low-temperature operation comprises a cutter body 1, wherein a clamping hole 3 is formed in one end of the cutter body 1, the other end of the cutter body 1 is a cutter head 2, the cutter head 2 is spade-shaped, a ceramic coating is sprayed on the outer surface of the cutter head 2, the temperature of surgical cutting is reduced through the ceramic coating, and the operation is guaranteed to be performed in a low-temperature state.
The tool head 2 is composed of a main cutting surface 201, a main cutting edge 202, an external cutting surface 203 and an internal cutting surface 204, wherein the diameter of the external cutting surface 203 is D, the diameter of the internal cutting surface 204 is D, the diameter between the external cutting surface 203 and the internal cutting surface 204 is H, and the width of the cutting edge of the main cutting edge 202 is 20-35 mu m.
The intersection of the major cutting surface 201 and the outer cutting surface 203 is the major cutting edge 202.
The included angle α between the main cutting surface 201 and the outer cutting surface 203 is 29 ° to 33 °, and the included angle α is calculated by α=arctg 2H/(D-D).
The included angle beta between the external cutting surface 203 and the cutter body 1 at one side of the external cutting surface 203 is 19-22 degrees.
The included angle theta between the main cutting surface 201 and the cutter body 1 at one side of the inner cutting surface 204 is 8-14 degrees, and the included angle theta is an included angle alpha-included angle beta.
When the shovel-shaped cutter head plasma cutter applied to low-temperature operation is used, medical staff inserts one end, provided with the clamping hole 3, of the cutter body 1 into electrode surgical equipment, and supplies current to the cutter body 1 through the electrode surgical equipment, so that the cutter head 2 on the cutter body 1 is attached with the current, and the focus part of a patient is cut through the main cutter blade 202, the main cutting surface 201 and the external cutting surface 203 on the cutter head 2.
While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
