Abstract
The invention discloses a tip rapid bending device for a coronary artery guide wire. The device comprises a finger stall which can be sleeved on a finger. The front end of the finger stall is in a conical shape and the rear end is in a cylindrical shape. The outer peripheral surface of the finger stall is provided with threads. From the rear end of the finger stall, to the front end of the finger stall, the thread pitches of the threads reduce gradually. The tip rapid bending device for a coronary artery guide wire can accurately and rapidly bend tip angles of a coronary artery guide wire, and rationally controls bending angles of the guide wire tip according to differences of cardiovascular branch angles of a patient, so that the tip of the coronary artery guide wire can smoothly enter the specific branch blood vessel.
Description
Technical field
The present invention relates to a kind of medical instrument, particularly to a kind of device that can control coronary guide wire tip bending angle according to actual needs.
Background technology
In recent years coronary artery that is narrow and that entirely shut is implemented percutaneous transluminal coronary angioplasty, it has also become one of universally acknowledged maximally effective means for the treatment of coronary heart disease.Coronary guide wire is a kind of instrument must used in percutaneous transluminal coronary angioplasty, can support be delivered at lesion vessels by seal wire, if and want to enable seal wire correctly to select and enter branch vessel smoothly, it is necessary in advance the tip of seal wire is bent out certain angle.The bending of wire tips was all that doctor completes the most by hand in the past, lacked the special device that can quickly bend wire tips so that the angle that seal wire bends out is accurate not, and then operation risk is increased.
For above-mentioned deficiency, need to design a kind of device that can control coronary guide wire tip bending angle according to actual needs, to solve the problems referred to above.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of coronary guide wire tip quick bender, the tip angle of coronary guide wire accurately and quickly can be bent by this coronary guide wire tip quick bender, according to the Branch Angle difference of patient's heart blood vessel, the bending angle of wire tips reasonably can be controlled.
It is an object of the invention to be achieved through the following technical solutions:
The coronary guide wire tip quick bender of the present invention, including the fingerstall can being set in above finger, the front end of described fingerstall be conical aft be cylinder, the outer circumference surface of described fingerstall has screw thread, is sequentially reduced to the pitch of screw thread described in fingerstall front end from fingerstall rear end.
Further, also including the cylindrical shell that can be closely set on fingerstall, described fingerstall circumferentially rotates cooperation axial restraint and is connected with described housing, described housing has along the upwardly extending slotted opening of fingerstall axle.
Further, described housing is made of clear material.
Further, above described fingerstall, thread groove edge threadingly is identified with graduation mark.
Further, the edge of described opening both sides, the wherein bottom chamfer of a lateral edges, the top chamfer at opposite side edge.
Further, described housing rear end be coaxially arranged with gear.
The invention have the benefit that the coronary guide wire tip quick bender of the present invention, including the fingerstall can being set in above finger, the front end of described fingerstall be conical aft be cylinder, have screw thread on the outer circumference surface of described fingerstall, be sequentially reduced to the pitch of screw thread described in fingerstall front end from fingerstall rear end.The tip angle of coronary guide wire can accurately and quickly be bent by the coronary guide wire tip quick bender of the present invention, according to the Branch Angle difference of patient's heart blood vessel, the bending angle of wire tips can reasonably be controlled, and then enable the tip of coronary guide wire to enter into smoothly in the branch vessel specified.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the perspective view of fingerstall in the quick bender of coronary guide wire tip of the present invention；
Fig. 2 is the perspective view of coronary guide wire tip of the present invention quick bender middle shell；
Fig. 3 is the perspective view that coronary guide wire tip of the present invention quick bender is overall.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in Figures 1 to 3: the coronary guide wire tip quick bender in the present embodiment, including the fingerstall 1 can being set in above finger, the front end 1a of described fingerstall be conical aft 1b be cylinder, screw thread 1c is had on the outer circumference surface of described fingerstall 1, being sequentially reduced from fingerstall rear end to the pitch of screw thread described in fingerstall front end, specifically, the thread groove width of described screw thread 1c is corresponding to the external diameter of seal wire.During use, the lever of the present invention can be set on doctor's forefinger on the other hand, then with the thumb of this hands, the tip of seal wire is pressed against in the thread groove of screw thread, bending is moved towards with what other hands bending seal wire made seal wire threadingly groove, select to be pressed against the tip of seal wire the diverse location of thread groove, different bending angles can be obtained, and then achieve the accurate control of the tip angle to coronary guide wire.
Further improvement as technique scheme, also include the cylindrical shell 2 that can be closely set on fingerstall, described fingerstall 1 circumferentially rotates cooperation axial restraint and is connected with described housing 2, have along fingerstall 1 axle upwardly extending slotted opening 2a on described housing 2, specifically, seal wire is allowed to insert between inside and the thread groove of screw thread of described housing 2.Above-mentioned improvement makes when bending wire tips, thumb press wire tips need not be used, only need to go out to be inserted into thread groove from the opening of housing by seal wire, then rotating housing can bend the tip of seal wire, improves the operability of lever of the present invention.
As the further improvement of technique scheme, described housing 2 is made of clear material, in order to is able to observe that the length of seal wire bending place by housing, and then reaches the accurate control to seal wire bending length.
As the further improvement of technique scheme, the thread groove edge of described fingerstall 1 the most threadingly 1c is identified with graduation mark 1d, to improve the accurate control to seal wire bending length further.
As the further improvement of technique scheme, the edge of described opening 2a both sides, the wherein bottom chamfer of a lateral edges, the top chamfer at opposite side edge so that opening 2a both sides of the edge are rounder and more smooth, and then prevent edge of opening scratch seal wire.
As the further improvement of technique scheme, described housing rear end be coaxially arranged with gear 2b.During use, handsetting gear can be carried out by thumb and control housing rotation on fingerstall, to improve the operability of lever of the present invention further.
Finally illustrate is, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent, without deviating from objective and the scope of technical solution of the present invention, it all should be contained in the middle of scope of the presently claimed invention.
