Abstract
The invention discloses a kind of medical guiding wire auxiliary holding devices.The present invention includes holder and spanner, holder forms stepped cylinder shape by the clamping cylindrical body and handle cylindrical body of coaxial line, it clamps cylindrical body and handle cylindrical body is connected by transition cambered surface, the side wall of clamping cylindrical body is provided with spanner placing groove, the second through-hole and tapped through hole is respectively set in spanner placing groove two side walls, through slot is arranged in the side wall for clamping cylindrical body and handle cylindrical body, and the outer peripheral surface of handle cylindrical body is provided with striped；One end of spanner is circular arc camber, and protrusion is provided at the top of the other end, and wrench body is provided with first through hole, and bolt passes through second through-hole, first through hole and tapped through hole and is attached by screw thread.The present invention effectively reduces during rotating seal wire since the seal wire caused by seal wire surface is smooth slips situation, and can at any time remove seal wire from clamping device, reduce the operating time of doctor.
Description
Technical field
The present invention relates to minimally-invasive vascular interventional technique fields, and in particular to a kind of medical guiding wire auxiliary holding device.
Background technique
Most of cardiovascular and cerebrovascular disease is to be treated by intervening operation, and intervene operation and need using seal wire.Doctor
It is general slowly to be promoted seal wire in blood vessel by rotation seal wire when using seal wire.Since seal wire diameter is less than 1 millimeter, seal wire
Surface is hard smooth, and doctor needs spiritual high concentration in use, and existing seal wire auxiliary holding device structure is multiple
Miscellaneous, small part is more, and volume is big, and is not easy to remove seal wire from clamping device.
Summary of the invention
The technical problem to be solved by the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of medical
The auxiliary holding device of seal wire.
Technical scheme is as follows:
A kind of auxiliary holding device of medical guiding wire, including holder and spanner, holder by coaxial line clamping cylindrical body and
Handle cylindrical body forms stepped cylinder shape, and clamping cylindrical body connects handle cylindrical body by transition cambered surface, clamps cylindrical body
Side wall is provided with spanner placing groove, and the second through-hole and tapped through hole is respectively set in spanner placing groove two side walls, clamps cylindrical body
Through slot is set with the side wall of handle cylindrical body, for the placement of seal wire, the outer peripheral surface of handle cylindrical body is provided with striped；Spanner
One end is circular arc camber, and protrusion is provided at the top of the other end, and wrench body is provided with first through hole, and it is logical that bolt passes through described second
Hole, first through hole and tapped through hole are attached by screw thread.
Respectively there are a circular pit, spanner pair in the medical guiding wire auxiliary holding device, spanner placing groove inner wall two sides
Position is answered to have round boss.When spanner pushes down seal wire, the thin boss of circle on spanner is stuck in spanner placing groove inner wall two sides
In round thin pit, prevent spanner from loosening.The through slot width of holder is 1 millimeter, and the inside circular arc camber radius of through slot is 0.5 milli
Rice.
The present invention is a kind of medical guiding wire auxiliary holding device, and material used in pedestal is organic material, passes through holder
Seal wire is clamped with spanner.Seal wire can be rotated by the handle of rotating clamp base, effectively reduce because seal wire surface it is smooth caused by
Seal wire slips situation, can at any time remove seal wire from clamping device, reduce the operating time of doctor.
The configuration of the present invention is simple, it is easy to operate, it is highly reliable when clamping seal wire, it at any time can be by seal wire from clamping device
It removes or installs；The holder of clamping device is manufactured using organic material, has certain flexibility, reduces the shearing force to seal wire, folder
The handle portion of device is held with striped, the frictional force of seal wire and hand is increased, facilitates the surgical procedure of doctor
Detailed description of the invention
Fig. 1 medical guiding wire auxiliary holding device explosive view；
Fig. 2 medical guiding wire auxiliary holding device installation diagram.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
The present invention includes holder 1 and spanner 2, holder by coaxial line clamping cylindrical body and handle cylindrical body group into a ladder
Cylindric, clamping cylindrical body connects handle cylindrical body by transition cambered surface, and the side wall for clamping cylindrical body is provided with spanner placing groove
6, the second through-hole 10 and tapped through hole 7 is respectively set in spanner placing groove two side walls, clamps the side of cylindrical body and handle cylindrical body
Through slot 8 is arranged in wall, and for the placement of seal wire, the outer peripheral surface of handle cylindrical body 9 is provided with striped；One end of spanner is circular arc camber
11, other end top is provided with protrusion 12, and wrench body is provided with first through hole 5, and bolt 3 passes through second through-hole, first
Through-hole and tapped through hole are attached by screw thread.
As shown in Figure 1, the first through hole 5 on spanner 2 is directed at the threaded hole 7 on holder 1 when installation, then bolt 3 is worn
It crosses the second through-hole 10 on holder 1, in the threaded hole 7 of precession holder 1, completes the installation of fixture.
As shown in Fig. 2, spanner 2 is unclamped in use, up move the protrusion 12 on spanner 2.Put seal wire into holder again
1 through slot 8 most the inside, closes spanner 2, and seal wire is stuck in the most the inside circular arc camber of through slot 8.To guarantee that spanner 2 does not loosen, pull
Round boss 13 on hand 2 is stuck in the circular pit 14 of 8 two sides of sipes.Can slowly it be turned by the handle 9 in rotating clamp base 1
Dynamic seal wire.
