Description
Technical field
The present invention relates to a kind of auxiliary surgical assistant piece of circular-pipe anastomat, particularly relate to a kind of guiding device of circular-pipe anastomat.
Background technology
Circular-pipe anastomat 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, have 2 kinds of operations, it is more difficult that circular-pipe anastomat enters operative site, is low rectal operation and gastric bypass operation respectively.To be diameter the be circular-pipe anastomat of 33 millimeters that the operation of the first low rectal adopts, 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 injected anus more difficult.To be diameter the be circular-pipe anastomat of 25 millimeters that the second gastric bypass operation adopts, small intestinal need be entered perform the operation, small intestinal is the digester tube of human body, inwall has a lot of mucosa, and circular-pipe anastomat due to end face larger, and owing to manufacturing, assembling reason, outer surface is not complete shiny surface, walks easily cause damage to mucosa at enteral.
The prior art solved the problem at present is the assistive device of a kind of circular-pipe anastomat that U.S. Patent application US20090204108 discloses, the nail bin groupware of aimming circle tubular anastomat 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 circular-pipe anastomat.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.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem, a kind of guiding device being applicable to circular-pipe anastomat is provided.
Object of the present invention is achieved through the following technical solutions:
The guiding device of circular-pipe anastomat, described circular-pipe anastomat comprises nail-anvil assembly, nail bin groupware, is fixed on the bend pipe of described nail bin groupware near-end, and to be arranged on movably in nail bin groupware and anvil pull rod for being connected with nail-anvil assembly, described guiding device is the body of a tubular, the far-end of described body is wedge shape, described body is movably coated on the periphery of described nail bin groupware, described guiding device can move between the primary importance of described nail bin groupware and the second position of described nail bin groupware
When described guiding device is positioned at primary importance, described nail bin groupware end face is covered by the most proximal end of body wedge-like portion,
When described guiding device is positioned at the second position, described nail bin groupware end face exceeds the end face of described body.
Further, the end face periphery of described body is that fillet is arranged.
Further, described guiding device is the tubular body of a rubber mass or plastics matter.
Further, the body of described guiding device is coated on the periphery of described nail bin groupware and part bend pipe movably.
Further, the near-end of described body becomes a hollow taper guiding edge to periphery diverging.
Further, described guiding is convexly equipped with at least one circle for anti-skidding projection along surface.
Further, described bend pipe is provided with the graduation mark for determining guiding device position.
Beneficial effect of the present invention is mainly reflected in: batter post face is arranged in the cross section due to guiding device far-end, makes operator successfully nail bin groupware is inserted into tissue, protects tissue, can not due to the excessive and damaged of the end face of nail bin groupware.The manufacture of this guiding device is simple, with low cost, is worth being greatly expanded.

Detailed description of the invention
A kind of guiding device of circular-pipe anastomat, as shown in Figure 1 and Figure 2, circular-pipe anastomat is consistent with of the prior art, the bend pipe 12 comprise nail-anvil assembly (meaning not shown in the figures), linking with nail bin groupware 11 is provided with graduation mark 14, and anvil pull rod 13 is arranged in nail bin groupware 11 movably.
Guiding device is the tubular body 2 comprising far-end and near-end of a rubber mass or plastics matter, as shown in Figure 1, the body 2 of guiding device is movably coated on the periphery of nail bin groupware 11 and part bend pipe 12, and certainly, body 2 also only can be coated on the periphery of nail bin groupware 11.Because nail bin groupware end face 110 end face is larger, not easily enter anus or other tubular openings, so the end face 20 of body 2 is arranged to there is certain angle between the parallel surface of nail bin groupware end face 110, body 2 far-end of guiding device is made to form wedge shape and more easily enter anus or other tubular openings, simultaneously, can not be stabbed when entering human body to make guiding device tissue, and fillet or lubricated or bag flexible glue are done in the end face of body 2 20 and the pipe pipe shaft junction of body 2.
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, and primary importance refers to the position of guiding device on circular-pipe anastomat during original state; After the second position refers to that nail bin groupware 11 enters anus or other tubular openings, when connecting operation between the tissue carrying out follow-up routine, the position residing for guiding device.
When guiding device is positioned at primary importance, as shown in Figure 1, now, the sidewall distal of nail bin groupware 11 is covered by guiding device completely, and after nail bin groupware 11 enters human body, guiding device is needed to pull out from bend pipe near-end, make the guiding device arrival second position as shown in Figure 2, guiding device is stopped when bend pipe near-end is drawn to graduation mark 14 position, now, the nail bin groupware 11 complete end face 20 from body 2 passes, afterwards, just can carry out conventional follow-up bookbinding operation, not repeat at this.
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 3, meanwhile, leads along 3 surfaces and is also convexly equipped with five circle projections 31 to increase frictional force, be convenient to grasp, more easily pull guiding device.Certainly, also can as shown in Figure 3, when with the body 2 of end face 20 and the guiding device of most preferred embodiment and other structures all identical, lead along being provided with some projections 31 on 3.Fig. 4, Fig. 5 then show respectively top view and the left view of Fig. 3.
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.
