Description
Technical field
The present invention relates to a kind of auxiliary surgical assistant piece of tubular binding strument, particularly relate to a kind of guiding device of tubular binding strument.
Background technology
Tubular binding strument is a kind of surgical instruments being widely used in surgery reconstruction of digestive tract, is made up of with percussion assembly the nail-head component of circle; The tubular type tissue coupled together by two sections of needs is placed between the nail anvil of nail-head component and nail bin, and the distance of adjustment nail anvil and nail bin carrys out grip tissue gradually, and then operation percussion assembly makes nail be shaped, and completes the connection of two sections of tissues.
In the operation technique of reality, having two kinds of tubular binding struments of performing the operation to enter pipeline more difficult, is low rectal operation and gastric bypass operation respectively.The first low rectal is performed the operation, and to be diameter the be tubular binding strument of 33 millimeters of employing, need per anum to perform the operation, because anus is a muscular opening, its diameter of normal condition is less, the apparatus of 33 millimeters is inserted into anus more difficult.The second gastric bypass operation, to be diameter the be tubular binding strument of 25 millimeters of employing, need enter small intestinal and perform the operation, small intestinal is the digester tube of human body, and inwall has a lot of mucosa, and tubular binding strument due to end face larger, and sufficiently oily, easily damage is caused to mucosa interior walking.
The prior art solved the problem at present is the assistive device of a kind of tubular binding strument that U.S. Patent application US20090204108 discloses, the nail bin groupware of the tubular Binding Instrument of aimming circle can enter human body and through intestinal, and this assistive device can be laid down from nail bin groupware after it arrives precalculated position, do not affect the subsequent operation of tubular binding strument.This assistive device can help doctor that nail bin groupware is successfully put into preposition, but this assistive device costly at present, can't be supplied to Chinese market widely.

Detailed description of the invention
A kind of guiding device of tubular binding strument, as shown in Figure 1 and Figure 2, tubular binding strument is consistent with prior art, comprise nail-anvil assembly (meaning not shown in the figures), nail bin groupware 11, be provided with graduation mark 14 and be fixed on the bend pipe 12 of nail bin groupware near-end, anvil pull rod 13 to be arranged in nail bin groupware 11 and movably for being connected with nail-anvil assembly.
Guiding device is that the body 2 of a tubular forms with the active segment 3 with far-end 31 and near-end 32, active segment 3 one-tenth hemispherical, a circular hole 33 is offered in the distalmost end of active segment 3, as shown in Figure 1, the body 2 of guiding device is coated on the periphery of nail bin groupware 11 and part bend pipe 12, only can certainly be coated on the periphery of nail bin groupware 11.
As shown in Figure 4, Figure 5, the active segment 3 of body 2 is by being ectonexine structure, outer 34 is body 2 itself, for fexible film material, and there is good elasticity, in order to strengthen the compressive strength of outer 34, be evenly fixedly installed 12 ribs 35 as internal layer at outer 34 inner surfacies, described reinforcement can be plastic cement material, with fexible film can adhesion or be injected into one.
Guiding device in the primary importance at nail bin groupware far-end and can move between the second position of nail bin groupware near-end.
Primary importance refers to the position of guiding device on tubular binding strument during original state; After the second position refers to that nail bin groupware 11 enters human body, when connecting operation between the tissue carrying out follow-up routine, the position residing for guiding device.
When nail bin groupware 11 enters human body, guiding device is positioned at primary importance, as shown in Figure 1, now, circular hole 33 diameter is more smaller than the maximum outside diameter of anvil pull rod 13, makes the remote card of anvil pull rod 13 in circular hole 33, provides support a little to ribs, harder ribs 35 makes active segment 3 can not concave when the pressure organized, and also can poke to be organized as subsequent procedures action and to prepare.
And after nail bin groupware 11 enters human body, guiding device is needed to pull out from bend pipe near-end, guiding device is made to reach second position when circular hole 33 struts, as shown in Figure 2, now, circular hole 33 struts, when nail bin groupware 11 stretches out from circular hole 33 due to shoring of nail bin groupware 11, due to the material of body 2, make the resilient periphery being coated on nail bin groupware 11 of circular hole 33.
Conveniently guiding device moves to bend pipe near-end by operator, the hollow taper guiding that the near-end of guiding device is arranged to disperse to periphery, along 4, meanwhile, leads along 4 surfaces and is also convexly equipped with four circle projections 41 to increase frictional force, thus more easily pull guiding device, as shown in Figures 1 to 6.During operation, hold guiding and pulled to operator direction by guiding device along 4, now the skin 34 of fexible film is owing to there being better elasticity, and the softened nail bin groupware 11 that enough makes of circular hole 33 passes through, until guiding device is moved to the graduation mark 14 place stopping action of bend pipe 12.And operation is afterwards usual way in prior art, do not repeat them here.
These are only preferred embodiment, sketch the second embodiment of the present invention respectively more below.
As shown in Figure 7, second embodiment is roughly the same with the guiding arrangement structure of most preferred embodiment, be that body 2 and the active segment 3 that is attached thereto of a tubular forms, the hollow taper guiding that the near-end of guiding device is arranged to disperse to periphery is along 4, simultaneously, guiding is also convexly equipped with four circle projections 41 to increase frictional force along 4 surfaces, and handled easily person uses.Unlike, active segment 3 is conical, and circular hole 33 is opened in the distalmost end of active segment 3.While being arranged on like this reduces costs, also well can play guiding function.
In addition, it should be noted that, the near-end that the application mentions refers to the one end near operator, on the contrary far-end.
The present invention compared with prior art has the following advantages:
(1) guiding device is due to its round and smooth appearance active segment, has not only helped operator more smoothly nail bin groupware to be put into tissue, and has protected tissue, can not due to the excessive and damaged of the end face of Binding Instrument.
(2) manufacture of this guiding device is simple, with low cost, is worth being applied widely.
The present invention still has multiple concrete embodiment, as in prior art by all technical schemes that pull bar replaces guiding to be formed along reaching the equivalent replacement of identical object and so on or equivalent transformation, all drop within the scope of protection of present invention.
