Description
Technical Field
The utility model belongs to the technical field of surgical instruments, and particularly relates to an orthopaedics limiter.
Background
Hip replacement involves resecting the patient's damaged femoral head, exposing the femoral head. After exposing the hip joint, the joint capsule of the hip joint is cut off, then the hip joint is dislocated, and after exposing the femoral head, the femoral head is sawed off at the femoral neck. When the pendulum saw is used for cutting bones, a limit protection device is not arranged around the pendulum saw, the bounce of the pendulum saw blade can cause iatrogenic damage, and the bounce of the pendulum saw blade can cause more bone burrs at the saw bones due to the lack of the limit protection device around the pendulum saw, so that the follow-up treatment is inconvenient.
Disclosure of Invention
In view of the above problems, an object of the present utility model is to: provides an orthopaedics limiter which solves the problems that the periphery of a pendulum saw lacks a limiting protection device when the hip joint replacement saw cuts the femoral head, the bounce of the pendulum saw blade can cause iatrogenic injury and bone burrs at the saw bone are more.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides an orthopedics stopper, includes stalk portion and head, the head sets up at the front end of stalk portion and with stalk portion integrated into one piece, the head comprises last plate body, lower plate body, link up on the head and seted up the spacing groove, the bottom shaping of lower plate body has broken face tooth.
The beneficial effects of the utility model are as follows: the head accessible bottom sets up lower plate body and broken face tooth convenient wedge in the femur, when operating personnel held the stalk portion, carries out spacingly to the pendulum saw piece through the spacing groove is stable.
In order to enable the head to be wedged in the femur with less effort;
as a further improvement of the above technical scheme: the lower plate body is an isosceles trapezoid plate structure with a wide upper part and a narrow lower part.
The beneficial effects of this improvement are: the head can be wedged into the femur through the bottom end of the lower plate body in a more labor-saving manner.
In order to enable the head to be wedged in the femur with less effort;
as a further improvement of the above technical scheme: the broken surface teeth are of triangular tooth-shaped structures.
The beneficial effects of this improvement are: the broken face teeth can reduce the contact area between the bottom end of the lower plate body and the femur, so that the head can be wedged into the femur in a relatively labor-saving manner.
In order to enable the head to be wedged in the femur with less effort;
as a further improvement of the above technical scheme: the bottom of the inner wall of the lower plate body is provided with a chamfering structure.
The beneficial effects of this improvement are: the chamfer structure of seting up of lower plate body bottom can reduce the area of contact of lower plate body bottom and femur, and then makes the head can be comparatively laborsaving wedge in the femur.
In order to effectively increase the cutting length of the swinging saw blade while ensuring the limiting effect of the limiting groove;
as a further improvement of the above technical scheme: the vertical projection shape of the limiting groove is a slender rectangle, and the limiting groove penetrates through the side surfaces of the two waists of the lower plate body.
The beneficial effects of this improvement are: the bottom of the swinging saw blade can swing in the directions of two waists of the lower plate body, so that the cutting length of the swinging saw blade is effectively increased.
For stable gripping of the handle;
as a further improvement of the above technical scheme: an anti-skid groove is formed in the side face of the handle.
The beneficial effects of this improvement are: the friction between the palm of an operator and the handle is increased due to the anti-skid grooves.
For stable gripping of the handle;
as a further improvement of the above technical scheme: thumb grooves are formed in the lateral sides of the two sides of the handle part between the anti-slip grooves and the head part.
The beneficial effects of this improvement are: the provision of the thumb grooves increases friction with the operator's thumb and handle.
None of the parts of the device are the same as or can be implemented using prior art.

Detailed Description
In order that those skilled in the art may better understand the technical solutions of the present utility model, the following detailed description of the present utility model with reference to the accompanying drawings is provided for exemplary and explanatory purposes only and should not be construed as limiting the scope of the present utility model.
Example 1:
as shown in fig. 1-4: the utility model provides an orthopedics stopper, includes stalk portion 1 and head 2, head 2 sets up at the front end of stalk portion 1 and with stalk portion 1 integrated into one piece, head 2 comprises last plate body 21, lower plate body 22, link up on the head 2 and seted up spacing groove 3, broken face tooth 23 has been formed to the bottom of lower plate body 22, the convenient wedge of lower plate body 22 and broken face tooth 23 that head 2 accessible bottom set up is in the femur, when operating personnel holds stalk portion 1, carries out the spacing to the pendulum saw blade through spacing groove 3 stability, lower plate body 22 is wide isosceles trapezoid board structure down, and the comparatively laborsaving wedge femur of bottom of head 2 accessible lower plate body 22, broken face tooth 23 is triangular tooth structure, and broken face tooth 23 can reduce the area of contact of lower plate body 22 bottom and femur, and the chamfer structure that the chamfer structure of seting up of lower plate body 22 bottom can reduce the area of contact of lower plate body 22 and femur, and then makes the side of lower plate body 22 wedge groove 2 have been set up for the side face groove 11 on the side face groove 11 of the operator between the side face 1 is enlarged, and the side face groove 11 is cut down in the side face groove 11 of the side face groove 1 is formed in the side face groove 11 of the side face groove 1 of the side face of the operator that the side face of the side face 1 is more than the side face of the palm of the driver, and the side face of the palm of the driver's 11.
The working principle of the technical scheme is as follows: after the femoral head is exposed, the device is wedged into the cut part of the femoral neck, and the difficulty of wedging the device into the femur is reduced by the lower plate body 22, the broken face teeth 23 and the chamfer structures arranged at the bottom end of the lower plate body 22; the swing saw blade is inserted into the limit groove 3, and the swing saw blade swings at a high speed in a reciprocating manner in the limit groove 3 formed in the head 2 to cut the femur; the arrangement of the lower plate body 22 improves the swinging, namely cutting angle of the swing saw blade in the limit groove 3; in order to ensure the stability of the device, an operator can hold the handle 1, the thumb is buckled on the thumb groove 12, and the anti-slip groove 11 is matched with the handle to play an effective anti-slip role.
