Abstract
The utility model provides a novel hook is visited to bidentate for arthroscopic surgery, is applicable to hooking up of in arthroscopic surgery knee joint kern episome. The utility model discloses take by visit hook handle (1), divide tooth draw -in groove (2), divide tooth spanner (3), hasp (4), visit shank (5), connecting rod (6), divide tooth a (7), the hook was visited to the bidentate that divides tooth b (8) to constitute technical scheme, when arthroscopic surgery operate, be half -cylinder under the normal conditions and divide tooth a (7) and branch tooth b (8) to hold the monodentate state in minute tooth spanner (3) under controlling together. Among the actual operation technique, if there is special circumstances, will divides tooth spanner (3) to pull and be on a parallel with when visiting hook handle (1) direction, and divide tooth a (7), divide tooth b (8) separately to form the bidentate and visit the hook. The utility model discloses structural design is simple, and the practicality is strong, is showing to have increased to visit the application range of hook in arthroscopic surgery.
Description
Technical field
This utility model belongs to medical technical field of medical instruments, relates generally to a kind of knuckle videoendoscopic surgery bidentate finger pin.
Background technology
The osteoarthrosis Minimally Invasive Surgery of human body is different with the operation of well-known conventional open, for instance be necessary for standby many special operating theater instruments in the clinical manipulation of arthrocsopic surgery corresponding with it. As the arthrocsopic surgery special equipment such as tissue grasper, taker, basket pincers, this wherein finger pin be indispensable basic operation instrument, it is equivalent to the finger of doctor, for detecting the tension force of tissue, toughness or tractive tissue etc. in operation. But presently used finger pin is single briar tooth, practical operation still comes with some shortcomings, such as in the single episome operation of knee joint rear chamber, separately take rear chamber to enter dataway operation and then increase operation wound, front road mirror and removal equipment are difficult to again simultaneously enter rear chamber operation, and monodentate finger pin can not meet again the operation needs as this particular procedure.
Utility model content
For problem existing in prior art, this utility model devises a kind of knuckle videoendoscopic surgery bidentate finger pin. See in appearance and common finger pin no significant difference of the prior art from bidentate finger pin, time in operation such as special requirement, finger pin can be made to become bidentate finger pin by controlling organization, take out the needs of operation with the single episome of satisfied picture knee joint rear chamber, solve deficiency of the prior art. For achieving the above object, the concrete technical scheme that this utility model is taked is: a kind of knuckle videoendoscopic surgery bidentate finger pin, is made up of finger pin handle, point tooth draw-in groove, point tooth spanner, snap close, connecting rod, finger pin bar, point tooth a, a point tooth b; Wherein: the upper position processing of finger pin handle front end has a point tooth draw-in groove; Tubular finger pin bar is arranged on the top of finger pin handle; Tooth spanner and snap close is divided to be arranged in point tooth draw-in groove; Connecting rod is connected through tubular finger pin bar one end with a point tooth spanner, and the other end connects a point tooth a; Dividing tooth spanner to be vertically mounted at connecting rod one end, the switch location of point tooth spanner is controlled by the snap close on finger pin handle;Connecting rod can along horizontal axis left-right rotation in tubular finger pin bar; Point tooth a and a point tooth b in semi-cylindrical form are separately fixed at connecting rod and the front end of finger pin bar, and point tooth a and the inner plane on point tooth b are mutually corresponding.
A kind of knuckle videoendoscopic surgery bidentate finger pin described in the utility model, solves the unicity problem that in prior art, common finger pin uses in operation. Taking out in operation at the single episome of knee joint rear chamber, camera lens and finger pin can simultaneously enter rear chamber, adopt bidentate finger pin in art in time, and episome is easy to be gone out from rear chamber hook, and episome subsequently takes out operation will become very easy. This utility model simple in construction, easy to operate, hence it is evident that to add finger pin effect in arthrocsopic surgery and purposes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is point tooth b enlarged diagram of semicircle column type shape in this utility model.
In figure: 1, finger pin hands handle; 2, tooth draw-in groove is divided; 3, tooth spanner is divided; 4, snap close; 5, finger pin bar; 6, connecting rod; 7, tooth a is divided; 8, tooth b is divided.
Detailed description of the invention
Detailed description of the invention of the present utility model is provided as follows below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of knuckle videoendoscopic surgery bidentate finger pin described in the utility model, it is made up of finger pin handle 1, point tooth draw-in groove 2, point tooth spanner 3, snap close 4, finger pin bar 5, connecting rod 6, point tooth a7, a point tooth b8; Wherein: processing on the top of finger pin handle 1 front end and have a point tooth draw-in groove 2, tubular finger pin bar (5) is arranged on the top of finger pin handle (1); Tooth spanner 3 and snap close 4 is divided to be contained in point tooth draw-in groove 2; Connecting rod 6 connects a point tooth spanner 3 through tubular finger pin bar 5 one end, and the other end connects a point tooth a7, and three constitutes an overall structure; Dividing tooth spanner 3 to be vertically mounted at connecting rod 6 one end, the switch location of point tooth spanner 3 is controlled by the snap close 4 on finger pin handle 1; Connecting rod 6 can along horizontal axis left-right rotation in tubular finger pin bar 5; Point tooth a7 and a point tooth b8 in semi-cylindrical form are separately fixed at connecting rod 6 and the front end of finger pin bar 5, and the inner plane of point tooth a7 and point tooth b8 is mutually corresponding. When a point tooth spanner 3 is perpendicular to finger pin handle 1, a point tooth a7 and point tooth b8 is combined one cylinder of composition, forms single finger pin, can do finger pin in general surgery and use. When a point tooth spanner 3 is pulled and is parallel to finger pin handle 1, point tooth a7, a point tooth b8 are formed separately bidentate finger pin and can use in particular procedure; Snap close 4 plays the opening and closing to point tooth spanner 3 and plays fixing position-limiting action.
