Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, the direct handling type handle for hysteroscope operation of the utility model, including connector 3 and one end
It is hinged on the first control section 1 and second control section 2 of 3 the same end of connector, the first control section 1 and second control section 2 are equal
For staight shank type, the middle part of the connector 3 is equipped with active pull rod 4, and the end of active pull rod 4 is hingedly there are two connector 5, and two
The other end of connector 5 is hinged with first control section 1 and second control section 2 respectively, the first control section 1 and second control section
Spring is equipped between 2 to strut the two.In its natural state, first control section 1 and second control section 2 are under the action of the spring
Open shape, and the end of active pull rod 4 is also under the action of connector 5 near the position of connector 3, at this time with activity
The connected binding clip 8 of pull rod 4, which is in, opens shape；When applying pressure to first control section 1 and second control section 2 closes up the two,
Two connectors 5 also close up to middle part, so that the end for the pull rod 4 that innervates is mobile to the direction far from connector 3, thus band
Dynamic active pull rod 4 controls binding clip 8 and closes up.
In order to reach preferably holding and operating effect, the first control section 1 and second control section 2 are disposed as rolling over
Curved, the bending direction of two handle parts is consistent, i.e., two handle parts institute in the plane, one of them lateral bending into handle part
Folding, another bends on the outside of handle part, and bending point is located at the hinged of connector 5 and first control section 1 and second control section 2
Point, bending angle α are 0~15 °.Handle part with certain bending angle can be more suitable for the position of hysteroscope operation Shi doctor,
More meet ergonomics, to reduce doctor's labor intensity, increases operation safety.Research and practical application by analysis, hair
Existing bending angle α has optimal using effect when being 12 °.
In order to improve the comfort level of grip, cambered surface knot is set by the outside of the first control section 1 and second control section 2
Structure, and it is equipped with skid resistance strip on surface, the skid resistance strip can be used and directly be obtained to the handle punching press moulding of metal material,
It can also be realized by the sleeve with non-slip groove of one plastics of socket.
For the spring for strutting first control section 1 and second control section 2, two schemes provided herein:
The first scheme is: as shown in Fig. 2, the spring is the torque spring 6a that the end of active pull rod 4 is arranged in, institute
The both ends for stating torque spring 6a, which are stuck on two connectors 5, struts two connectors 5.The V of torque spring 6a, that is, common
Font spring, middle part are fixed on the end of active pull rod 4, and both ends are stuck on two connectors 5, in its natural state,
Two connectors 5 are strutted by torque spring 6a, to strut first control section 1 and second control section 2, and the pull rod that innervates
4 is mobile to 3 direction of connector；It then needs to overcome torque spring 6a when needing to close up first control section 1 and second control section 2
Torsion, the torsion and palm grip form equilibrant force, to realize the accurate control of handle opening-closing.
Second scheme is: as shown in figure 3, the spring is the tension spring 6b covered on active pull rod 4, tension spring
One end of 6b is connected with 4 end of active pull rod, and the other end and connector 3 are to even.In its natural state, body spring 6b is drawn to tense
Active pull rod 4 is in the end of active pull rod 4 near the position of connector 3, and under the action of connector 5, first is held
Portion 1 and second control section 2 are in open configuration.And when closing up first control section 1 and second control section 2, then it needs to overcome drawing
The pulling force of power spring 6b, the pulling force and palm grip form equilibrant force, to realize the accurate control of handle opening-closing.
The first control section 1 and second control section 2 are respectively equipped with mutually engageable activity far from one end of connector 3
Grab 11 and fixed grab 21, one end and first control section 1 of the activity grab 11 are hinged.Due in its natural state, hand
Handle and binding clip 8 not easily pass through mirror sheath and enter uterine cavity all under the action of the spring in shape is opened, not easily contained storage, setting activity
After grab 11 and fixed grab 21, when enter uterine cavity and do not need using when then first control section 1 and second control section 2 are closed
Hold together, is then stuck on fixed grab 21 with activity grab 11, handle and binding clip 8 is finally made to be in and close up shape under the action of the spring
State.
Further, it is hinged with spanner 12 close to one end of connector 3 in the first control section 1, the spanner 12
It pulls end and is located at 1 outside of first control section, the movable end positioned inside is hinged with connecting rod 13, the other end of the connecting rod 13
It is hinged with the middle part of movable grab 11.There is the structure that can pull spanner 12 by thumb or index finger, thus control activity
The clamping or disengaging of grab 11 and fixed grab 21.It takes in operation engineering sometimes for being pullled tissue or dragged, in list
Hand can also first pass through spanner 12 when operating to control after movable grab 11 carrys out grip tissue with fixed 21 clamping of grab and be rotated further by
Or handle is pullled, make to operate more laborsaving, conveniently.To realize different clamping dynamics, the fixed grab 21 can use spine
Rack gear is substituted.
Above-mentioned handle arrangement can be adapted for most hysteroscope operation instrument, and have the hand of above-mentioned direct handling type handle
Art instrument further includes claw beam 7 and binding clip 8, and one end of the claw beam 7 is fixedly connected with connector 3 far from one end of handle, binding clip
8 are arranged in the other end of claw beam 7, and the claw beam 7 is hollow structure, the active pull rod 4 pass through after connector 3 and claw beam 7 with
Binding clip 8 is hinged, passes through the opening and closing of the flexible realization binding clip 8 of active pull rod 4.Claw beam 7 is generally made of titanium alloy material, claw beam
7 outer diameter 3.5mm or so, length 350mm or so.Binding clip 8 can be scissor, scissors straight, elastic separating plier, wave pincers, rat-tooth forceps etc.,
Darkening process is preferably done on 8 surface of binding clip, is avoided light tone metal from occurring in hysteroscope reflective, is brought visual fatigue to doctor.
Traditional right-angle type handle is changed to direct handling type handle by the utility model, and doctor's arm can be made in hysteroscope operation
In more comfortable posture, slow down doctor's fatigue, and handle ratio is controlled merely with thumb control by the grip of entire palm
Handle processed is more easier to hold and exert a force, one-handed performance can easily rotational handle, be conducive to grasping tissue, and cooperate again
The equilibrant force that spring provides controls the opening and closing of binding clip, the opening and closing degree of binding clip can be preferably controlled, to improve grasping tissue
Precision, improve the safety of operation, have good practicability and application prospect.
