Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a telescoping device of drag hook.
Background
The drag hook can be used in surgical operation often, and skin muscle cuts the back tissue and can contract and be unfavorable for the operation during the operation, just so need hold skin muscle to both sides respectively with the drag hook, and the operation field of vision in the middle of so just can expose, makes things convenient for doctor's operation. The existing drag hook has various types, the camera lens is arranged on the visual drag hook, and the functions of displaying, amplifying and the like of the drag hook position in real time can be realized by connecting the display, so that the drag hook brings convenience to the surgical operation of doctors to a great extent, and the success rate of the surgical operation is also improved.
However, the existing visual draw hook has some defects, and due to the difference of body types of people, the general draw hook with the rod length which cannot be adjusted has the problems of overlong or overlong length sometimes, which is not beneficial to the operation of a doctor and reduces the operation efficiency.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a telescoping device of drag hook, technical scheme is as follows:
the utility model provides a telescoping device of drag hook, includes outer tube, interior sleeve pipe and camera lens pole, interior sleeve pipe slide and inlay in the inner wall of outer tube, the camera lens pole with outer tube connection, the outer tube still be equipped with motor, screw rod and screw rod cover, the motor locate in the outer tube, the output and the screw rod of motor are connected, the screw rod with screw rod cover threaded connection, the screw rod cover with interior tube connection.
Furthermore, the inner sleeve is provided with an elastic convex bead, the outer sleeve is provided with a limiting hole, and the elastic convex bead and the hole are mutually inserted.
Furthermore, an organ pipe is arranged on the lens rod.
Has the advantages that:
the utility model discloses can make the drag hook reach the extension and the effect that shortens, this technical scheme effect can satisfy the people of different height physiques and use in the in-service use, reaches better universality, and economic benefits is good, and this structure is convenient to be operated simultaneously, can improve the operating efficiency that the doctor performed the operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged schematic view of the telescopic structure in the embodiment of the present invention.
In the figure, 1-outer sleeve, 2-inner sleeve, 3-lens rod, 4-motor, 5-screw, 6-screw sleeve and 7-organ tube.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the use, through motor 4 positive and negative rotation, its output drives screw rod 5 and rotates, and screw rod cover 6 with 5 threaded connection of screw rod is at screw rod 5 reciprocating motion to drive interior sleeve pipe 2 that is connected with screw rod cover 6 and displace from top to bottom, reach interior sleeve pipe 2's flexible effect with this, consequently locate the terminal drag hook of interior sleeve pipe 2 and can stretch out and draw back the adjustment according to the demand, supply the better operation of doctor. This embodiment reaches the effect of extension and shortening through the extending structure who installs above-mentioned function, and this technical scheme effect can reach better universality in the in-service use, and economic benefits is good, and this convenient operation of structure can improve the operating efficiency that the doctor was operated simultaneously.
Preferably, the inner sleeve 2 is provided with an elastic convex bead, the outer sleeve 1 is provided with a limiting hole, and the elastic convex bead and the hole are mutually inserted. The mutual insertion of the elastic convex beads and the holes plays a role in limiting, and the structure can effectively prevent the excessive displacement or shaking of the inner sleeve 2, so that the operation of a doctor is prevented from being influenced, and the operation efficiency of the doctor can be improved.
Preferably, the lens rod 3 is provided with an organ pipe 7. For the flexible of better cooperation drag hook of camera lens pole, the flexible section of drag hook in outer tube and interior sleeve pipe outside is located to phoenix's harp tube 7 preferred on it, and when the drag hook extension, organ pipe 7 has certain extensibility, the extension effect of cooperation drag hook that can be fine to do not influence the normal use of drag hook, vice versa in the same way, because of organ pipe 7 has certain compressibility, effect when the adaptation drag hook pole that also can be fine shortens.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
