Description
Technical field
The present invention relates to medicine technology fields, and in particular to a kind of laparoscopic surgery drawing hook.
Background technique
Laparoscopic surgery is the invasive methods that a new development is got up, and is that one of the following operation method development necessarily becomes
Gesture.With advancing by leaps and bounds for industrial manufacturing technology, be fused to carry out new technology, the new method of related discipline have established firm base
Plinth, in addition the operation that doctor is more and more consummate, so that many past open operations have been replaced by intracavity operation now,
Considerably increase surgical selection chance.Retroperitoneoscopictechnique conventional method is to make three 1 centimetre of small notch in patient's waist, respectively
The pipe-like service aisle that insertion one is called " trocar ", later every operation, which passes through these three pipelines, to carry out, then with special
The lengthening surgical instrument of system completes the step same as open surgery under television monitoring, reaches same surgical effect.With
Has there are the operation invasive methods such as two holes or even single hole at present in the progress of surgical technic.
Draw hook is a kind of instrument being widely used in laparoscopic surgery, and its role is to pull tissue, exposure visual area is
Laparoscopic surgery goes on smoothly offer convenience.Traditional drawing hook generally comprises a bracing wire and is fixed at bracing wire both ends
Coupler body, a coupler body protrude into it is intraperitoneal catch on tissue, another coupler body hook on other instruments realize fix.But this mode
Have the defects that certain: 1, for traditional approach in order to adapt to the drawings of various tissues, coupler body generally will not be too small, so to
Drawing hook is put into intraperitoneal, a biggish art hole must be needed.2, since the bracing wire length of conventional drawing hook is fixed, nothing
Method carries out the adjusting of length, causes the coupler body of fixing end to need to select different fixed points, use is extremely inconvenient.
Summary of the invention
Fixed laparoscopic surgery is facilitated to pull hook the purpose of the present invention is to provide a kind of.
For achieving the above object, the technical scheme adopted by the invention is that: a kind of laparoscopic surgery pulls hook, including
Traction chain and the first coupler body and the second coupler body for being fixed at traction chain both ends, the traction chain is by several interconnected
Annulus is constituted.
Preferably, the length of the traction chain is 20cm.
Preferably, first coupler body is made of memory alloy material, and the first coupler body is in hook when being higher than transition temperature
Shape is lower than linearly when transition temperature.
Preferably, the transition temperature is 35 DEG C.
Preferably, for first coupler body when being higher than transition temperature, end crimps in the shape of a spiral constitutes round end.
Preferably, be arranged with silica gel isolated tube outside first coupler body, the thickness of the silica gel isolated tube 0.5-1mm it
Between.
Beneficial effects of the present invention embody a concentrated reflection of, and the adjustment of drawing length can be carried out easily and fast, using extremely
It is convenient.Specifically, the present invention in use, the one end for being provided with the first coupler body is protruded into intraperitoneal, and catches on tissue；
One end of the second coupler body is provided with around after fixed point, the second coupler body catches on annulus and can be pulled.With traditional mode phase
Than, the second coupler body selectivity of the invention catches on different annulus, actually it is achieved that the adjustment of traction chain folded length, into
And the adjustment of entire length of the present invention is realized, to adapt to different drawing demands.Meanwhile the first coupler body of the invention is preferred
It is made up of memorial alloy, it is linearly when being lower than transition temperature, that is, be linear, therefore art under normal temperature state
Normal use of the invention is nor affected in the lesser situation in hole, is suitble to be applied in invasive surgery.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is structural schematic diagram of the structure shown in Fig. 1 when being lower than transition temperature；
Fig. 3 is the scheme of installation of silica gel isolated tube.
Specific embodiment
A kind of laparoscopic surgery in conjunction with shown in Fig. 1-3 pulls hook, including traction chain 3 and is fixed at traction chain 3
First coupler body 1 and the second coupler body 2 at both ends, the traction chain 3 are made of several annulus interconnected.Usual first coupler body 1
It is directly fixed on the annulus at 3 both ends of traction chain with the second coupler body 2, traction chain 3 is typically chosen the stainless steel of medical grade
Material is made, and the length of traction chain 3 is usually 20cm, it is of course also possible to specifically designed according to actual needs, such as: 30cm,
10cm etc..
The present invention in use, the one end for being provided with the first coupler body 1 is protruded into intraperitoneal, and catches on tissue；Setting
There is one end of the second coupler body 2 around after fixed point, the second coupler body 2 catches on annulus and can be pulled.That is the present invention is solid
The fixed form of fixed end is that traction chain 3 is realized fixation around fixed point, this is directly caught on using the second coupler body 2 with traditional
Fixed point has apparent difference.The selection of fixed point can be on small operating table or other instruments, and traction chain 3 is consolidated around rod-shaped
Fixed point.Compared with the traditional way, what the second coupler body 2 of the invention was selective catches on different annulus, actually just realizes
The adjustment of 3 folded length of traction chain, and then the adjustment of entire length of the present invention is realized, so that adapting to different drawings needs
It asks.
Furthermore it is also possible to be further improved, first coupler body 1 is made of memory alloy material, and the first coupler body 1 is in height
In hook-shaped when transition temperature, it is lower than linearly when transition temperature.The transition temperature is to adapt to body temperature to need, generally
Selection is lower than body temperature 2-3 degree, about 35 DEG C.In other words, that is, when being higher than 35 DEG C, the first coupler body 1 is lower than 35 in hook-shaped
DEG C when, the first coupler body 1 is linearly.Setting in this way, the present invention is in use, under normal temperature state, that is, does not extend into abdomen
When intracavitary, the first coupler body 1 is linear, can be protruded into the first coupler body 1 by minimum art hole intraperitoneal；First coupler body 1
Into after abdominal cavity, as temperature increases, becomes hook-shaped, tissue can be pulled at this time.Therefore, even if in the lesser situation in art hole
Under nor affect on normal use of the invention, be suitble to be applied in invasive surgery.
In addition, the end injury tissue of the first coupler body 1, better way are also possible that as shown in body 1 in order to prevent, institute
The first coupler body 1 is stated when being higher than transition temperature, end crimps in the shape of a spiral constitutes round end 4.On the one hand round end 4 can prevent tissue de-
Hook avoids damage to tissue on the other hand it is also possible that the end of the first coupler body 1 is more smooth.
Further, silica gel isolated tube 5, the thickness of the silica gel isolated tube 5 are arranged with outside the first coupler body 1 of the present invention
Between 0.5-1mm.By the setting of silica gel isolated tube 5, it can reduce the first coupler body 1 to the sensibility of temperature, make the first hook
The deformation of body 1 has certain buffer time, prevents maloperation.Such as: the first coupler body 1 when touching wound stomach wall, due to
The presence of silica gel isolated tube 5 will not immediately begin to deformation, and need certain buffer time.Or operator's hand is being taken
When taking the present invention, the short time hold the first coupler body 1 will not cause the present invention deformation occurs.Certainly, it is needed quickly for some
For being performed the operation, it can also be not provided with silica gel isolated tube 5, but this prevent the skilled operation degree requirement to doctor higher.
