Description

Minimally invasive fracture reduction top rod

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a minimally invasive fracture reduction top rod.

Background

In the clinical orthopedics surgery, the fracture end shifts to enable the auxiliary reduction to be pushed through the reduction top rod, however, the reduction top rod in the prior art is not easy to carry out minimally invasive reduction, slipping is easy to occur during operation, and the operation is relatively inconvenient.

Disclosure of Invention

The utility model aims to provide a minimally invasive fracture reduction ejector rod to solve the problems in the background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a fracture minimal access reposition top stick, includes connecting rod and top stick head, top stick head fixed mounting is in the end of connecting rod, the front end of top stick head is crescent platykurtic, the other end head fixed mounting of connecting rod has the handle.

Preferably, the outer diameter of the top rod head is the same as the outer diameter of the joint of the connecting rod.

Preferably, both the front side and the rear side of the top rod head incline to the crescent.

Preferably, an arc-shaped reinforcing block is fixedly arranged between the connecting rod and the two ends of the top rod head.

Preferably, the side ends of the crescent concave part of the top rod head are close to the two end heads and are conical surfaces, and the two end heads of the top rod head are cambered surfaces.

Compared with the prior art, the utility model has the beneficial effects that: the utility model discloses a minimally invasive fracture reduction ejector rod, which is characterized in that the front end of an ejector rod head is set to be flat in a crescent shape, so that the crescent shape of the ejector rod head can be used for being matched with a bone body in use to facilitate reduction operation, different crescent shapes are arranged according to the shapes of different bone bodies to facilitate adaptation of different bone bodies, the outer diameters of the joints of the ejector rod head and a connecting rod are the same, the occurrence of edges and corners can be reduced, the connection stability can be improved, the two side ends of the ejector rod head are reinforced by an arc-shaped reinforcing block, the firm strength is improved, the ejector rod head is prevented from slipping or breaking when in use, the pain of a patient is increased, the workload of medical staff is further avoided, the minimally invasive fracture reduction ejector rod is convenient to use, the bone body reduction is assisted, the slipping phenomenon is avoided, the accuracy of operation is guaranteed, the safety of the patient is improved, and the working efficiency and practicability of a doctor are improved.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a fracture wicresoft resets top stick, includes connecting rod 1 and top stick head 2, top stick head 2 fixed mounting is in the end of connecting rod 1, the front end of top stick head 2 is crescent platykurtic, the other end head fixed mounting of connecting rod 1 has handle 3.

The handle 3 is a wood handle.

The front end of the top rod head 2 is in a crescent flat shape and is adapted according to the sizes of different bones, so that the crescent shape of the top rod head 2 can be matched with the bones in use, the resetting operation is convenient, and the slipping phenomenon is avoided.

Specifically, the outer diameter of the top rod head 2 is the same as the outer diameter of the joint of the connecting rod 1, the connection tightness of the top rod head 2 and the connecting rod 1 is increased, and the stability of the top rod head 2 can be increased.

Specifically, both front and back sides of the tip rod head 2 are inclined to the crescent, so that the tip rod head 2 can conveniently enter a patient from the minimally invasive opening.

Specifically, arc reinforcing blocks 4 are fixedly arranged between the connecting rod 1 and the two ends of the top rod head 2, so that the safety performance of the arc reinforcing blocks is improved, the two ends of the top rod head 2 are prevented from being broken, and secondary injury is caused to a patient.

Specifically, the crescent concave side ends of the top rod head 2 are close to the two end heads to form conical surfaces, and the two end heads of the top rod head 2 are cambered surfaces.

Working principle: when the bone body is reset in the minimally invasive surgery, the crescent radian of the head 2 which is the same as the cambered surface of the bone body to be reset is selected, then the handle 3 is held by hands, the head 2 is extended into the bone body from the minimally invasive opening, at the moment, the crescent flat shape of the head 2 is attached to the surface of the bone body, the force for pushing the handle 3 is applied, and then the head 2 pushes the bone body to reset, and the crescent flat shape of the head 2 is tightly attached to the surface of the bone body, so that the risk of slipping is avoided in the pushing process, the operation safety is improved, the damage to a patient caused by slipping is avoided, the operation accuracy is ensured, and the working efficiency of doctors is improved.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
