Description
Technical field
The utility model relates to a kind of Screw and holds and get device, belongs to medical instruments field, is particularly useful in bone surgery.
Background technology
Screw is held and is got device and belong to a kind of general apparatus at medical device industry, when being usually applicable to twist nail, nutting, Screw hold get device be usually shaped with in the one or both ends of shank clamp holder portion apply external force, during use, threadingly direction of rotation applies power at shank, just can twist bolt or nut.Have plenty of one end and be fixedly connected with design with handle, be commonly called as integral type; Have plenty of with hydraulic quick coupler with the use of, be commonly called as quick-changing type.
Medical device industry field screw installation and removal instrument is varied, has fork spanner, box spanner, combination wrenches, double offset ring spanner etc., double offset ring spanner two ends have the working end of band hexagon ring or 12 corner apertures, be applicable to working space narrow and small, the occasion of common wrench can not be suitable for.Current our company has gone out a kind of novel Screw through research and development department's development and design and has held and get device.
Summary of the invention
The purpose of this utility model is: for prior art Problems existing, the invention provides a kind of Screw and holds and get device, more convenient and quicker installation and removal are carried out to Screw, improve procedure efficiency, reduce the misery of performing the operation and bringing to patient.
The technical solution of the utility model is as follows:
The utility model is made up of cross like spanner bar 1, internal jacket 2, external jacket 3, pin 4, lining 5 and little perpendicular handle 6, and little perpendicular handle 6 is made up of bakelite bar 7, inner core 8, pin 9 and spill spin block 10.
Cross like spanner bar 1: left end is cross head, in order to twist screw, rear is Step Shaft immediately, the position of Step Shaft and internal jacket 2 close contact ensure that the axiality of cross like spanner bar 1 and internal jacket 2, and the position of Step Shaft and the non-close contact of internal jacket 2 makes cross like spanner bar 1 more easily load internal jacket 2.
Internal jacket 2: left end outside is that the axle of a band tapering is connected with circular shaft, the inner hole in ladder shaft-like, and both sides are with the opening of symmetry, are used for left end shaft is extended out, and facilitate the installation and use in later stage, right-hand member is the axle having groove.
External jacket 3: the inner hole for band tapering is connected with stepped axis hole, and outside right-hand member has four symmetrical grooves, the plate-like place design of low order end is to conveniently hold movement when adjusting assembly.
Lining 5: cylinder axis left end inside has the hole of matching with cross like spanner bar 1, and right-hand member opens a pin hole, is used for fixing on little perpendicular handle 6.
The utility model has the following advantages:
The test of the utility model finished product after our company's processing, fully show that the utility model structural design is practical, use simple to operate, good hand touch, outward appearance is simple, has the feature of practicality, creativeness and novelty, is applicable to the use in bone surgery.
