Abstract
The invention relates to an operation utensil, in particular to a pair of temporal-mandibular joint opening pliers used for opening temporal-mandibular joints. The pliers have convenient operation and wide operation view, and can be fixed and locked. The temporal-mandibular joint opening pliers are composed of a handle one, a handle two, a groove clamp spring, a projection clamp spring, a locking convex plate one, a locking convex plate two, a connection pin shaft and a lock making device; the head part of the opening pliers is inserted into a joint space when in use; a cylinder table arranged on the lock making device is rotated after the joint is opened to lead the lock making device to be tightly clamped on the locking convex plate one and on the locking convex plate two; V-shaped clamp grooves on the locking convex plate one and the locking convex plate two are meshed mutually; pretightening force is generated on the V-shaped clamp grooves by the undrawn groove clamp spring and the projection clamp spring, so as to lead the V-shaped clamp grooves to be meshed stably, thus ensuring fixed locking use condition of the temporal-mandibular joint opening pliers in operation.
Description
Technical field
The present invention relates to a kind of operational tool, particularly a kind ofly be used to strut temporomandibular joint, easy to operate and surgical field of view is open, but and the temporal-mandibular joint opening pliers of fixing and locking.
Background technology
Performing an operation, when running into the situation that need strut temporomandibular joint, the most frequently used method that struts temporomandibular joint peels off that son struts method, mosquito forceps struts method and the tip reduction forceps struts method, the drawback of these three kinds of methods is to skid easily when strutting the joint, strut poor effect, slippage also can damage other tissue, causes unnecessary damage; After strutting temporomandibular joint, surgical field of view is very narrow and small, is inconvenient to observe the state of an illness and operation technique; Can't the fixing operation instrument under softened state, need an assistant to assist toward contact, fixedly softened state often because the inharmonic operation of two people cooperates, causes surgical wound damage expansion.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, and is easy to use, especially is easy to fixedly strut the temporomandibular joint state, is difficult for skidding and temporal-mandibular joint opening pliers that surgical field of view is open.
For solving the problems of the technologies described above, the present invention realizes as follows: temporal-mandibular joint opening pliers of the present invention is made up of handle one, handle two, groove jump ring, protruding jump ring, locking boss one, locking boss two, connection bearing pin and locking device; The end wedgewise shape of handle one and handle two, outer surface is evenly equipped with anti-slip tank, and handle one and handle two rely on the connection bearing pin fixedly connected, and handle one and handle two can rotate around connecting bearing pin, and the angle that struts fully between back handle one and the handle two is 120 degree; One end of groove jump ring has a groove, and the other end relies on steady pin to be fixedly connected on the medial surface of handle one; One end of projection jump ring has a projection, and the other end relies on steady pin to be fixedly connected on the medial surface of handle two; The projection of projection jump ring is connected in the groove of groove jump ring, and can slide along groove; Locking boss one is fixedly connected on the medial surface of handle one, and vertical with handle one medial surface, is evenly equipped with " V " type draw-in groove on the locking boss one, is provided with a circular arc concave surface in the end of locking boss one; Locking boss two is fixedly connected on the medial surface of handle two, and vertical with handle two medial surface, is evenly equipped with " V " type draw-in groove on the locking boss two; " V " type draw-in groove on locking boss one and the locking boss two can be meshing with each other; Locking device is fixedly connected on the locking boss one, is two cylinder tables, and first cylinder table is fixedly connected on the locking boss one, and another cylinder table is fixedlyed connected with first cylinder table by bolt.
The cervical region of described temporal-mandibular joint opening pliers can be straight neck structure or has the curved strength structure of curved neck.
The end sides of described temporal-mandibular joint opening pliers can be even surface or has the cambered surface of indent.
Good effect of the present invention: temporal-mandibular joint opening pliers of the present invention, temporal-mandibular joint opening pliers head one is flat-sided flat, and a side intermediate projections meets the dissect physiology structure at human body remporomandibular joint position, struts fixing-stable in the process, can be to each side's slippage; The temporal-mandibular joint opening pliers head end is wedge shape, is convenient to insert in the joint space; The temporal-mandibular joint opening pliers connecting portion has 120 ° range of activity, struts in the process fully to expose surgical field of view, makes things convenient for the patient to operate; After temporal-mandibular joint opening pliers strutted the joint space, manpower was saved in the operation that can undergo surgery behind the locking locking device.
