Description
Technical field
The present invention relates to a kind of auxiliary surgical assistant piece of tubular binding strument, relate in particular to a kind of guiding device of tubular binding strument.
Background technology
Tubular binding strument is a kind of surgical instruments that is widely used in surgery reconstruction of digestive tract, is comprised of the nail-head component of circle and percussion assembly; The tubular type tissue that two sections needs are coupled together is placed between the nail anvil and nail bin of nail-head component, adjusts the distance of nail anvil and nail bin and comes gradually grip tissue, and then operation percussion assembly is shaped nail, finishes the connection of two sections tissues.
In the operation technique of reality, there is the tubular binding strument of two kinds of operations to enter relatively difficulty of pipeline, be respectively low rectal operation and gastric bypass operation.The first low rectal operation, employing be that diameter is 33 millimeters tubular binding strument, need per anum to perform the operation because anus is a flesh opening, its diameter of normal condition is less, and 33 millimeters apparatuses are inserted into relatively difficulty of anus.The second gastric bypass operation, employing be that diameter is 25 millimeters tubular binding strument, need enter small intestinal and perform the operation, small intestinal is the digester tube of human body, and inwall has a lot of mucosas, and tubular binding strument is because end face is larger, and sufficiently oily, walk easily to the mucosa injury interior.
The prior art that addresses the above problem at present is the assistive device of a kind of tubular binding strument of U.S. Patent application US20090204108 announcement, nail bin groupware that can the tubular Binding Instrument of aimming circle enters human body and passes intestinal, and after it arrives the precalculated position, can lay down this assistive device from nail bin groupware, do not affect the subsequent operation of tubular binding strument.This assistive device can help the doctor that nail bin groupware is successfully put into preposition, but this assistive device is relatively more expensive at present, can't be offered widely Chinese market.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem, a kind of guiding device that is applicable to tubular binding strument simple in structure is provided.
Purpose of the present invention is achieved through the following technical solutions:

The specific embodiment
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 in the bend pipe 12 of nail bin groupware near-end that anvil pull rod 13 is arranged on movably in the nail bin groupware 11 and is used for being connected with nail-anvil assembly.
Guiding device is that the body 2 of a tubular and the active segment 3 with far-end 31 and near-end 32 form, 3 one-tenth hemisphericals of active segment, distal-most end at active segment 3 offers a circular hole 33, 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, can certainly only be coated on the periphery of nail bin groupware 11.
Such as Fig. 4, shown in Figure 5, the active segment 3 of body 2 is by being the ectonexine structure, outer 34 is that body 2 is own, be the fexible film material, and have good elasticity, in order to strengthen the compressive strength of skin 34, evenly be 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 can move in the primary importance of nail bin groupware far-end and between the second position of nail bin groupware near-end.
Primary importance refers to guiding device position during original state on tubular binding strument; After the second position refers to that nail bin groupware 11 enters human body, when carrying out connecting operation between the tissue of follow-up routine, the residing position of guiding device.
When nail bin groupware 11 enters human body, guiding device is positioned at primary importance, as shown in Figure 1, at this moment, circular hole 33 diameters are more smaller than the maximum outside diameter of anvil pull rod 13, so that the remote card of anvil pull rod 13 in circular hole 33, provides support a little to ribs, harder ribs 35 also can be poked and is organized as subsequent procedures action and prepares so that active segment 3 can not concave in the pressure of being organized.
And after nail bin groupware 11 enters human body, guiding device need to be pulled out from the bend pipe near-end, so that the second position that guiding device reaches circular hole 33 when strutting, as shown in Figure 2, at this moment, circular hole 33 is owing to shoring of nail bin groupware 11 struts, when nail bin groupware 11 stretches out from circular hole 33, because the material of body 2 is so that the circular hole 33 resilient peripheries that are coated on nail bin groupware 11.
For the handled easily person moves guiding device to the bend pipe near-end, the near-end of guiding device is arranged to lead along 4 to the hollow taper that periphery is dispersed, and simultaneously, guiding also convexes with four circle projections 41 to increase frictional force along 4 surfaces, thereby easier pulling guiding device is extremely shown in Figure 6 such as Fig. 1.During operation, holding guiding along 4 with guiding device to operator's direction pulling, this moment fexible film skin 34 because better elasticity is arranged, circular hole 33 is strutted enough makes nail bin groupware 11 pass through, until graduation mark 14 places that guiding device is moved to bend pipe 12 stop action.And operation afterwards is usual way in the prior art, does not repeat them here.
Below only for most preferred embodiment of the present invention, below sketch respectively again the second embodiment of the present invention.
As shown in Figure 7, the guiding arrangement structure of the second embodiment and most preferred embodiment is roughly the same, the body 2 that is a tubular forms with the active segment 3 that is attached thereto, the near-end of guiding device is arranged to lead along 4 to the hollow taper that periphery is dispersed, simultaneously, guiding also convexes with four circle projections 41 to increase frictional force along 4 surfaces, the handled easily person uses.Different is, active segment 3 is conical, and circular hole 33 is opened in the distal-most end of active segment 3.Being arranged on when reducing cost so also can well be played guiding function.
In addition, need to prove that the near-end that the application mentions refers to the end near the operator, on the contrary far-end.
The present invention compared with prior art has the following advantages:
(1) guiding device has not only helped the operator more smoothly nail bin groupware to be put into tissue, and has protected tissue because its round and smooth appearance active segment, can be owing to the excessive and damaged of the end face of Binding Instrument.
(2) manufacturing of this guiding device is simple, and is with low cost, is worth being applied widely.
The present invention still has multiple concrete embodiment, as replacing guiding along all technical schemes that replacement or equivalent transformation form that are equal to that reach identical purpose and so on by pull bar in the prior art, all drops within the scope of protection of present invention.
