Abstract
The invention discloses a hollow trephine provided with a push rod. The hollow trephine comprises a hollow trephine body and a push rod; the hollow trephine body comprises a trephine head, a connecting rod and a cross rod, the trephine head is cylindrical, one end of the trephine head is fixedly connected with the cross rod through the connecting rod, the cross rod is vertical to the trephine head and the connecting rod, a round hole is formed in the other end of the trephine head, axis of the round hole is coincided with axis of the trephine head in position, a strip-shaped hole in the axis direction of the trephine head is formed in the outer wall of the trephine head, and sawteeth are formed at the end where the round hole is located on the trephine head; the push rod is cylindrical, the push rod is slidably arranged in the round hole; and a pushing block is arranged at one end, close to the cross rod, on the outer wall of the push rod, a clamping slot is formed in one end, close to the cross rod, on the long side wall of a strip-shaped slot, and the pushing block can be clamped on the clamping slot. By virtue of the way, the hollow trephine disclosed by the invention has the advantages that a bone column clamped in the hollow trephine can be conveniently taken out, so that operation time is shortened and anesthesia risk is reduced; and the bone column can be clamped at the upper part of the hollow trephine when being not used, so that normal use of the hollow trephine is not influenced.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of hollow trepan with push rod.
Background technology
Fracture patient clinically, especially with Cranial defect patient, it usually needs bone grafting, the bone object tool that takes clinically is mainly osteotome and hollow trepan at present.Osteotome needs bigger otch in taking bone process, mainly takes cortical bone, destroys for district's profile.Hollow trepan can drill through spongy bone, and required otch is little, and wound is less, the spongy bone taken out is more beneficial for bone resorption and utilizes, but often bone post is stuck in hollow trepan in taking bone process, it is difficult to take out bone post in hollow trepan, cause operating time to extend, increase anesthetic risks.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of hollow trepan with push rod, the bone post being stuck in hollow trepan can be taken out conveniently, to shorten operating time, to reduce anesthetic risks, it is also possible to be fastened on the top of hollow trepan in the not used time, do not affect the normal use of hollow trepan；Its simple in construction, easy to use.
For solving above-mentioned technical problem, the technical scheme that the present invention adopts is: provide a kind of hollow trepan with push rod, including hollow trepan body and push rod；Described hollow trepan body includes trepan head, connecting rod and cross bar, trepan head is column type, one end of trepan head is connected by connecting rod and cross bar are fixing, cross bar is perpendicular to trepan head and connecting rod, the other end of trepan head has circular hole, the axis of circular hole overlaps with the axial location of trepan head, and the outer wall of trepan head has the bar hole of trepan head axis direction, and on trepan head, circular hole place end is provided with sawtooth；It is characterized in that: described push rod is column type, and push rod is slidably disposed in circular hole；On described push rod outer wall, the one end near cross bar is provided with pushing block, and on the long sidewall of described bar-shaped trough, the one end near cross bar has draw-in groove, and pushing block may be stuck on draw-in groove.
Preferably, described pushing block includes fixture block and contiguous block, and fixture block is fixed on described push rod by contiguous block, and contiguous block may be stuck in described draw-in groove.
Preferably, described push rod and pushing block are stainless steel material.
The invention has the beneficial effects as follows: the present invention can be taken out conveniently the bone post being stuck in hollow trepan, to shorten operating time, to reduce anesthetic risks, it is also possible to be fastened on the top of hollow trepan in the not used time, do not affect the normal use of hollow trepan.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of hollow trepan one preferred embodiment with push rod of the present invention；
Fig. 2 is the perspective view that a kind of hollow trepan one with push rod of the present invention uses state.
In accompanying drawing, the labelling of each parts is as follows: 1, drill bit；2, connecting rod；3, cross bar；4, push rod；5, pushing block.
Detailed description of the invention
Below in conjunction with accompanying drawing, presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
Referring to Fig. 1 and Fig. 2, the embodiment of the present invention includes:
A kind of hollow trepan with push rod, including hollow trepan body and push rod 4；Described hollow trepan body includes trepan head 1, connecting rod 2 and cross bar 3, trepan head 1 is in column type, one end of trepan head 1 is connected by connecting rod 2 is fixing with cross bar 3, cross bar 3 is perpendicular to trepan head 1 and connecting rod 2, the other end of trepan head 1 has circular hole, the axis of circular hole overlaps with the axial location of trepan head 1, and the outer wall of trepan head 1 has the bar hole of trepan head 1 axis direction, and on trepan head 1, circular hole place end is provided with sawtooth；It is characterized in that: described push rod 4 is in column type, and push rod 4 is slidably disposed in circular hole；On described push rod 4 outer wall, the one end near cross bar 3 is provided with pushing block 5, and on the long sidewall of described bar-shaped trough, the one end near cross bar 3 has draw-in groove, and pushing block 5 may be stuck on draw-in groove.Described push rod 4 and pushing block 5 are stainless steel material, it is possible to rinse easily, do not worry getting rusty, and impact uses.Described pushing block 4 includes fixture block and contiguous block, fixture block is fixed on described push rod 4 by contiguous block, and contiguous block may be stuck in described draw-in groove, is limited in draw-in groove by fixture block and push rod 4 by contiguous block, to realize blocking push rod 4, push rod 4 is made to be fixed on the top of trepan head.During use, rotating pushing block 5 and make pushing block 5 no longer be stuck on draw-in groove, and promote pushing block 5, push rod 4 moves along the axis direction of trepan head 1, is released by the bone post being stuck in trepan head 1；During without using, promote pushing block 5 to trepan head top and rotate pushing block 5, pushing block 5 being stuck on draw-in groove, by pushing block 5, push rod 4 is fixed on the top of trepan head 1.
The present invention can be taken out conveniently the bone post being stuck in hollow trepan, to shorten operating time, to reduce anesthetic risks, it is also possible to be fastened on the top of hollow trepan in the not used time, does not affect the normal use of hollow trepan；Its simple in construction, easy to use.
