Abstract
The invention discloses a cervical vertebra expander which comprises a connecting pipe. The connecting pipe is provided with a working mechanism, a stop motion mechanism and a drive mechanism. The cervical vertebra expander is characterized in that the working mechanism comprises a fixed expanding arm and a movable expanding arm, the fixed expanding arm is arranged at the front end of the connecting pipe, the movable expanding arm is movably arranged on the connecting pipe through a connecting rod, and the connecting rod is movably connected with the drive mechanism. As an improvement, the drive mechanism comprises a transmission mechanism which is arranged on the connecting pipe. One end of the transmission mechanism is connected with the connecting rod, and the other end of the transmission mechanism is connected with a spanner which is arranged on the connecting pipe. The transmission mechanism is a gear component. Two ends of the gear component are respectively connected with the spanner and the connecting rod in a transmitted mode. The stop motion mechanism comprises a stop slice which is arranged on the connecting pipe, and the stop slice is connected with the gear component in a transmitted mode. The cervical vertebra expander is reasonable in design and simple in structure, is capable of achieving entering from two sides, and meanwhile the cervical vertebra expander can effectively protect a jaw portion and guarantees effects of a surgery.
Description
Technical field
The invention belongs to medical instruments field, specifically, relate to a kind of cervical vertebra dilator.
Background technology
At present, serious situation in eye very when cervical vertebra is injured, and also cervical vertebra is one of skeleton of wanting of body weight for humans, the quality of its operation has directly determined the human body ability to act.Instantly in cervical operation, the cervical vertebra dilator is a kind of apparatus commonly used, has played good effect in operation.But existing dilator is to be undertaken by a side of human body mostly.This one-sided mode that enters causes unnecessary trouble to operation technique sometimes, and one-sided entering can cause to a certain degree injury to jaw section, even can cause irreversible injury to jaw section.
Summary of the invention
The technical problem to be solved in the present invention is to overcome defects, provide a kind of reasonable in design, simple in structure, can realize that bilateral enters and protect the cervical vertebra dilator of jaw section.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of cervical vertebra dilator, comprise connection tube, the front end of connection tube is provided with operating mechanism, the rear portion is provided with stop mechanism and driving mechanism, it is characterized in that: described operating mechanism comprises and fixedly struts arm and activity struts arm, fixedly strut the front end that arm is arranged on connection tube, activity struts arm and is movably arranged on connection tube by connecting rod, and connecting rod is flexibly connected driving mechanism.
As a kind of improvement, described driving mechanism comprises the drive mechanism that is arranged on connection tube; One end of described drive mechanism connects connecting rod, and the other end is connected with spanner, and spanner is arranged on connection tube.
As a kind of improvement, described drive mechanism is gear assembly, the two ends of gear assembly be in transmission connection respectively spanner and connecting rod.
As a kind of improvement, described connecting rod is the body of rod of being made by titanium alloy material.
As a kind of improvement, described stop mechanism comprises the retaining sheet that is arranged on connection tube, the retaining sheet gear assembly that is in transmission connection.
As a kind of improvement, be provided with elastic connecting device between described retaining sheet and connection tube.
As a kind of improvement, described elastic connecting device is spring, and spring is the spring of being made by stainless steel material.
As a kind of improvement, describedly fixedly strut arm and the movable arm that struts is all to strut arm by what titanium alloy material was made.
As a kind of improvement, the diameter of described connection tube is 1-2cm, and connection tube is the body of being made by titanium alloy material.
Owing to having adopted technique scheme, compared with prior art, be provided with one in the present invention and fixedly strut arm and an activity struts arm, activity struts between arm and connection tube and is provided with connecting rod, and connecting rod is flexibly connected spanner, utilizes spanner to control the distraction angle that struts between arm.Such design has realized that dilator in operation is entered by left side or the right side of human body, has realized the variation that enters, has avoided the one-sided injury that enters jaw section.The present invention is reasonable in design, and is simple in structure, can realize that bilateral enters, and simultaneously the present invention can effectively protect jaw section, guaranteed the effect of operation.
The invention will be further described below in conjunction with the drawings and specific embodiments simultaneously.
