Background technique
Since hysteroscope technology in 1988 for the first time human body application since, hysteroscope instrument cooperate hysteroscope technology development walked
A year more than 20 are spent.It is original from hysteroscope instrument, the improvement of instrument is never stopped.The three of two class instruments are big to improve aspect point
Not are as follows: instrument binding clip interface, man-machine interface, movement mapping relations.Researcher is made that perhaps hysteroscope instrument in terms of these three
Improve, among these, major Instruments, Inc is made that different improvement in man-machine interface, and many research achievements are finally put into more
Clinical use simultaneously obtains good reflection.However, since simple transmission system is limited, and the huge amount of labour clinically,
Surgeon still feels existing instrument, and there are rooms for improvement.Existing instrument fixed angle brings following problems: due to work
Plane and wrist joint plane have difference in height, cause endoscope-assistant surgery doctor's wrist joint ruler partially/oar is inclined；Incorrect wrist joint height is also
It will increase the burden of elbow joint and shoulder joint；Wrist joint also needs the weight of burden instrument itself.
Surgeon is in the case where long-time uses hysteroscope instrument, due to working face and wrist joint when finding many
Plane has difference in height, cause endoscope-assistant surgery doctor's wrist joint ruler partially/oar is inclined, especially certain extreme positions, and due to not just
True wrist joint height also will increase the burden of elbow joint and shoulder joint, and the fatigue in each joint of upper limb easily occurs for surgeon.
The moiety by weight of burden instrument itself is also needed when along with wrist joint major part, discomfort, the pain of wrist joint and hand are one
A universal phenomenon.The WOLF company of Germany appreciates this problem, improves handle contours and designs and increase one kind and holds
Mode is held, but does not touch the basic of problem, is only used as a kind of optional alternative solution.

Specific embodiment
The utility model is described in further details below with reference to Figure of description and specific embodiment.
Fig. 1 to Fig. 4 shows a kind of embodiment of the utility model hysteroscope instrument handle rotation adjustment device, including shaft
1 and a pair of of handle 2 for being sleeved in shaft 1 and it is a pair of adjust turntable 3, one of turntable 3 that adjusts is located at 1 end of shaft,
Another adjusts turntable 3 and is located between a pair of of handle 2 and is installed with casing connecting rod 4 on the adjusting turntable 3, adjusts turntable 3 and its
Handle 2 with side direction is in circumferential tooth socket disengaging type connection.In use, first by handle 2 and adjust turntable 3 and separate, then basis
The grip and angular turn a pair of handle 2 of operator makes angle between a pair of of handle 2 and a pair of of handle 2 in
Between the angle that adjusts between turntable 3 adjust to required angle, then turntable 3 will be adjusted and it is matched with 2 tooth socket of handle of side direction
Locking to be closed, endoscope-assistant surgery can be finally carried out, the rotation of a pair of of handle 2 in operation will drive the rotation of intermediate regulations turntable 3,
To be converted into moving forward and backward for casing connecting rod 4.For more traditional hysteroscope instrument handle structure, the utility model is turned by adjusting
Disk 3 and its with the handle 2 of side direction be in that circumferential tooth socket disengaging type connects, on the one hand make angle between a pair of of handle 2 and
Angle between a pair of of handle 2 and intermediate regulations turntable 3 has adjustability, improves the flexibility used；On the other hand, tooth socket
Cooperation, so that overall structure is simple and compact, is connected firmly, substantially increases the reliability used.
In the present embodiment, turntable 3 is adjusted in the side that disengaging type connects and is equipped with circumferentially spaced double wedge 31, handle 2
It is equipped with circumferentially spaced groove 21 in the side of disengaging type connection, double wedge 31 is connect with 21 disengaging type of groove.In the structure,
Double wedge 31 adjusts 3 side of turntable in circumferentially-spaced be arranged in, and groove 21 is then arranged in 2 side of handle in circumferentially-spaced, needs
When adjustment angle, then double wedge 31 is separated with groove 21, then rotates a pair of of handle 2 to required angle, when operated, then double wedge 31
It is positioned with both groove 21 cooperations, it is simple and practical in structure.
In other embodiments, double wedge 31 and groove 21 are alternatively positioned in handle 2 and adjust on turntable 3, equally can be real
Existing double wedge 31 is connect with 21 disengaging type of groove.
In the present embodiment, adjusts and be installed with spring 5 between the handle 2 adjacent with side direction with it of turntable 3.The spring 5 rises
To separation adjusting turntable 3 and handle 2 effect, i.e. lock state when, spring 5 is compressed configuration, when eliminating coupling mechanism force, spring 5
Restoring deformation drives adjusting turntable 3 to separate with handle 2.
In the present embodiment, the both ends of shaft 1 are equipped with for set lever 2 and adjust the locking member 6 of turntable 3.The lock
Tight component 6 carries out compression locking to the adjusting turntable 3 and handle 2 at 1 both ends of shaft, compresses spring 5, and guarantee a pair of of handle
2 are closely contacted with each other with a pair of turntable 3 that adjusts.
In the present embodiment, locking member 6 includes cam operating switch 61 and locking closure 62, cam operating switch 61 and locking closure 62
The both ends of shaft 1 are divided in, cam operating switch 61 and shaft 1 are movably hinged.In the structure, cam operating switch 61 and lock
Lid 62 plays limit effect to the adjusting turntable 3 and handle 2 at both ends first, when locked, pulls cam operating switch 61, makes it
Cam pushing tow adjusts turntable 3, adjusts turntable 3 and is successively transmitted power by spring 5, finally realizes a pair of of handle 2 and a pair of of adjusting
Turntable 3 is closely contacted with each other, and when disengaged, is pulled cam operating switch 61, so that its cam is turned to another side, at this time jacking force
It disappears, spring 5, which restores deformation, drives adjusting turntable 3 to separate with handle 2.
In the present embodiment, a pair of of handle 2 is in front and back angled relationships.In this way, guaranteeing the feasibility of operation.
In the present embodiment, the interval angles section between each double wedge 31 is set as 5 ° to 90 °.In the structure, Primary regulation
Interval angles just equilateral shape formed by each double wedge 31 determine.When composition is regular quadrangle, interval angles are 90 degree；Composition
When for regular hexagon, interval angles are 60 degree；When composition is octagon, interval angles are 45 degree；When composition is regualr decagon,
Interval angles are 36 degree；When composition is dodecagon, interval angles are 30 degree.The composition of each double wedge 31 of the present embodiment is positive ten
Two side shapes, the i.e. interval angles of Primary regulation are 30 degree, and so on, to guarantee the density of adjustment.
Although the utility model is disclosed as above with preferred embodiment, it is not intended to limit the utility model.It is any
Those skilled in the art, in the case where not departing from technical solutions of the utility model range, all using the disclosure above
Technology contents many possible changes and modifications are made to technical solutions of the utility model, or be revised as the equivalent of equivalent variations
Embodiment.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model technical spirit to the above reality
Any simple modifications, equivalents, and modifications that example is done are applied, should all be fallen in the range of technical solutions of the utility model protection.
