Abstract
The invention discloses a kind of operation on oral cavity far-end operation crown scissors, belong to area of medical devices, and the crown scissors can be applied in operation on oral cavity by remote control.
Description
Technical field
The present invention relates to field of medical products, the crown scissors in specifically a kind of oral cavity.
Background technology
Crown scissors is the surgical instrument often to be used in oral surgery ligation, and its object is to go to cut to ligature
Silk.
Existing crown scissors is mainly the structure similar to scissors, and people holds scissors with a firm grip part, passes through the effect of cylinder lever
Lower control cutter head cuts ligature in turn, but due to sometimes for larger power, and according to lever principle, and scissors will be will do
It is very big, at oral cavity operation just unusual not aspect in the case of being made big, need to block light sometimes, especially influence
The progress of operation.
Invention content
It is an object of the invention to：A kind of operation on oral cavity far-end operation crown scissors, the crown scissors by remote control,
It specifically includes：
Cutter head, the cutter head include the first cutter head, the second cutter head, mounting base, first cutter head and the second cutter head
It is hinged and is hinged in mounting base at articulated shaft, the mounting base is equipped with a pair of opposite conduit, the first cutter head
It is connected separately with pull rod with the end of the second cutter head, pull rod is hinged on drive link, under the power of the offer of drive link, first
Cutter head and the second cutter head move in conduit；
Pincers pipe, the one end for clamping pipe are fixedly connected with cutter head, and connection, pincers pipe is internally provided with scissors handle for the other end and scissors
Movement pass to the drive link of cutter head；
Scissors handle, the scissors is including handle, and handle is two, and the fixing end of handle is hinged on rotation seat, is cut
Hilt includes connecting rod, and the both ends of connecting rod are connected with handle with the end of drive link respectively；
Drive link, the connecting rod of the both ends of drive link respectively with the pull rod of cutter head and scissors handle are hinged.
Scissors by drive link control cutter head, in the present invention, scissors by connecting rod control drive link movement,
Drive link further controls two cutter heads by hinged pull rod.In some embodiments, the end of two cutter heads is that can have
A shifting chute, if there are one pins to be stuck in this shifting chute simultaneously, the opening and closing of control cutter head is pulled by drive link, still
Find that this design, the opening and closing of cutter head be not smooth in an experiment, it is difficult to used in operation on oral cavity, so the present invention carried out into
The improvement of one step is connected with the end of cutter head respectively by two pull rods, this is equivalent to the movement of scissors handle to carry out inverse
To design, in order to reverse-engineer, present invention employs following schemes：First, it is provided with conduit at the position of mounting base,
The end of cutter head would not be mounted seat and block this when, can move freely；Simultaneously in motion transmission, clamp is in thick stick
Bar, the length of connecting rod are less than the length of pull rod, in this way scissors it is bigger in the case of, can be larger with clamp to cutter head
Pressure, and pull rod can be designed to shorter, shorter, the increase leverage of connecting rod design.The side that the present invention uses
Case can not block light, improve the operating space in oral cavity, further increase surgical effect in distal end memory precise manipulation.
But the operation of lever of the present invention also brings disadvantage while bringing advantage, lever drive is in the present invention
One big disadvantage is that human hand is not easy to experience the grip force of cutter head, and to solve the above-mentioned problems, drive link of the invention includes
The third drive link and the second drive link being connect with cutter head, the third drive link are equipped with protrusion, the phase of the second drive link
Position is answered to be equipped with the second recess portion, the depth of the second recess portion is more than protrusion, and the bottom end of the end of protrusion and the second recess portion passes through connection
Spring connects, and when protrusion is stuck in completely in the second recess portion, connecting spring is in tension.In the process used, third
The protrusion of drive link is stuck in the recess portion of the second drive link, and at this time spring is in tension, in a smaller power range
It is interior, rotating bar is drawn, third drive link and the second drive link will not relatively move, when the chucking power of binding clip is very big, the drawing of drive link
In the case of power is prodigious, third drive link and the second drive link have relative movement, can reduce the clamping of cutter head this when
Power, for example when cutter head accidentally clamps bone tooth, prevent the damage to tooth.
As an improvement, the drive link further includes with scissors the first drive link connecting, the first drive link and second
Drive link connects, and the first drive link and the second drive link can be rotated perpendicular to pincers pipe axial direction, and the end for clamping pipe is equipped with position
The inner wall of bulge loop in pincers pipe periphery, rotation seat is equipped with and the concave ring groove of bulge loop cooperation, and concave ring groove and bulge loop cooperation are so that rotation
Seat can be around pincers pipe axial rotation.Above-mentioned rotary device greatly facilitates the flexible operating of doctor, and in this hair
In bright, need to rotate rotation of the scissors drive link to be considered, that is, drive link and the small of the stock need Simultaneous Stabilization to rotate, and are
These are solved, drive link is divided into multistage by the present invention, can mutually be rotated between multistage, and is equipped on the outer wall of pincers pipe
Can be relative to the rotation seat of pincers pipe rotation, rotation seat and scissors being hinged, for the use of, control pincers pipe is motionless, rotation turn
Dynamic seat, entire scissors are operated that can turn to accurate position with the drive link being connected.
As an improvement, the end of second drive link makes first equipped with the clamping portion for going deep into first drive link
Drive link and the second drive link can relatively rotate, and the first drive link is equipped with and the first recess portion of clamping portion cooperation
As an improvement, set on the second drive link there are one fixed seat and being socketed with resetting spring, one end of resetting spring and
Fixed seat connects, and the other end is connected with pincers pipe, and resetting spring enables under no outer force effect, and cutter head resets to opening shape
State.Using above-mentioned resetting spring, when unclamping the external force of scissors handle, binding clip is then restored to deployed position, aspect surgical staff
Operation.
