The chisel head of bone tumour excision sword designs into Y type branch, when the bone face arch such as excision osteoma, can operate according to the bellied characteristics of bone face, synthesizes multiple osteotome chisel head and simplifies surgical instruments, reduces the operation misery.

Description

Bone tumor resection knife
Technical Field
The utility model belongs to the technical field of medical instrument and specifically relates to a bone tumour excision sword.
Background
An osteotome is a medical instrument frequently used in general bone surgery and mainly used for removing a bulge or a spur generated on the surface of a patient's bone, and is a surgical instrument used for trimming and chiseling a bone when performing bone surgery. The osteotome is divided into a flat osteotome, a round osteotome, an empty shell chisel and other composition forms, and the main technical index is that the cutting edge of the osteotome is sharp and has no phenomena of edge breakage and edge rolling; the connection part of the osteotome is firmly fixed and cannot loosen or fall off during working; because traditional osteotome area of contact is undersize, the osteotome drops easily during the collision to chisel head has weakened the power of exerting to the difficult control of action body application of force direction and osteotome atress direction, and the same effort need exert bigger power, pollutes the operation region easily moreover and leads to the infection.
Disclosure of Invention
An object of the utility model is to provide a bone tumour excision sword can be protruding with the bone face such as multiple angle cutting osteoma, synthesizes multiple osteotome chisel head and simplifies surgical instruments, reduces the operation misery.
In order to achieve the purpose, the bone tumor resection knife of the utility model comprises a handle and a chisel head connected with one end of the handle, wherein the end part of the chisel head is provided with a cutting edge; the chisel head is Y-shaped branch, the Y-shaped branch of the chisel head is a first branch and a second branch, the first branch and the second branch are connected through a groove, a first convex blade is arranged at the tail end of the first branch, a second convex blade is arranged at the tail end of the second branch, a concave blade is arranged at the tail end of the groove, and the first convex blade, the concave blade and the second convex blade are connected smoothly.
The bottom of the chisel head is in an upward convex arc shape.
An inclined connecting rod is arranged between the handle and the chisel head.
The included angle between the handle and the inclined connecting rod is 120-165 degrees, and the included angle between the chisel head and the inclined connecting rod is 120-165 degrees.
The handle is parallel to the chisel head.
The end of the handle is provided with a stress support which is of a circular cake-shaped structure, and a connecting handle is arranged between the handle and the stress support.
The length of the first branch and the length of the second branch of the chisel head are the same, the length of the groove is shorter than the length of the first branch and the length of the second branch, and the first branch, the groove and the second branch are chisel heads with two ends protruding and middle depressed.
The included angle between the first branch and the second branch of the chisel head is 30-45 degrees.
The included angle between the first branch and the bottom of the groove is 100-125 degrees, and the included angle between the second branch and the bottom of the groove is 100-125 degrees.
The utility model relates to a bone tumour excision sword, its beneficial effect lies in: the chisel head of the osteotome is designed into a Y-shaped branch, when the bone surface such as osteoma is removed and the like is convex, the operation can be carried out according to the convex characteristics of the bone surface, the surgical instruments are simplified by integrating various osteotome chisel heads, and the pain of the operation is reduced.

Detailed Description
Example 1
As shown in fig. 1-3, the bone tumor resection knife of the present invention comprises a handle 4 and a chisel head 3 connected to one end of the handle 4, wherein the end of the chisel head 3 is provided with a blade 1; the chisel head 3 is Y-shaped branch, the Y-shaped branch of the chisel head 3 is a first branch and a second branch, the first branch and the second branch are connected through a groove 2, a first convex blade is arranged at the tail end of the first branch, a second convex blade is arranged at the tail end of the second branch, a concave blade 7 is arranged at the tail end of the groove 2, and the first convex blade, the concave blade 7 and the second convex blade are connected smoothly.
The bottom of chisel head 3 is the epirelief arc shape, as shown in fig. 2, in a bone tumor excision sword right side view, the bottom of chisel head 3 is the arc structure of epirelief.
An inclined connecting rod 6 is arranged between the handle 4 and the chisel head 3.
The included angle between the handle 4 and the inclined connecting rod 6 is 120 degrees, and the included angle between the chisel head 3 and the inclined connecting rod 6 is 145 degrees.
The handle 4 is parallel to the chisel head 3.
The end of the handle 4 is provided with a stress support 5, the stress support 5 is of a circular cake-shaped structure, and a connecting handle is arranged between the handle 4 and the stress support 5.
The lengths of the first branch and the second branch of the chisel head 3 are the same, the length of the groove 2 is shorter than the lengths of the first branch and the second branch, and the first branch, the groove 2 and the second branch are chisel heads with two convex ends and a concave middle.
