Abstract
The utility model relates to a lasso used for holding and locating the rectum. The lasso is characterized by comprising a cannula (3) and a handle (1). A connection rope (4) is arranged in the cannula (3) and penetrates through the cannula (3), and one end of the connection rope (4) is connected with a hook. The lasso has the advantages that the structure is simple, operation is convenient, locating is accurate, convenience is brought to operations by doctors, and damage to the intestinal canal during the operations is relieved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of for controlling the lasso trick of location rectum.
Background technology
At present in the auxiliary rectal cancer surgery of peritoneoscope, because cannot entering abdominal cavity with hands, operation Shi doctor touches intestinal tube, need to adopt special-purpose tonger to clamp free rectum, this not only will have suitable dynamics to guarantee can not damage intestinal tube, also to draw to patient, to create a good work space to all directions, so having relatively high expectations to doctor.
In the situation that tumor is less, needing to use the capable art of colonoscope location, be generally that a relevant position metal clip of folder at tumor place outside intestinal wall carrys out labelling, but after labelling, metal clip easily comes off and need to reorientate behind location, and this makes operation process complicated and loaded down with trivial details.
Under existing condition, free rectum may make tumor break, and tumor tissues is come off in enteric cavity.If halfway flushing easily makes tumor planting, and the existence due to ampulla of rectum, making needs 2 ~ 3 nail bins from disconnected closed intestinal tube after free end, not only makes medical expense increase also because closed line angle of cut place may become to follow closely the bad generation that causes anastomotic leakage.
Summary of the invention
The purpose of this utility model is to address the deficiencies of the prior art, and provides a kind of special equipment for controlling location rectum.
The purpose of this utility model is achieved by the following technical programs:
For controlling a lasso trick for location rectum, it is characterized in that comprising sleeve pipe and handle thereof, in sleeve pipe, be provided with connecting rope, connecting rope is through sleeve pipe, and its one end is connected with hook.
Described handle one side is provided with and the orthogonal clamping screw of its axis, and clamping screw is through handle, and its bottom is placed in sleeve pipe, and when clamping screw bottom is threaded on sleeve lining, clamping screw forms location with connecting rope and coordinates.
Described hook comprises plunger body, and plunger body one end is hemispherical, the other end is provided with and the close-fitting boss of internal surface of sleeve pipe, and plunger body one side is provided with pocket for the punch head.
Described pocket for the punch head comprises and the orthogonal open slot of plunger body axis, and open slot one side is provided with wedge-shaped slot, and wedge-shaped slot and open slot are interconnected.
Described connecting rope is steel wire rope, and sleeve pipe, hook all adopt stainless steel to make.
The problem existing for prior art, the beneficial effect that this utility model exists is:
1, can control safely and effectively and block enteric cavity in working order time, make the attention of surgical staff all concentrate on the free of rectum and expose above, and not worry because the position of clamping and dynamics be not to secondary damage occurs rectum;
2, in the situation that tumor is less, in art behind colonoscope location, lasso trick is moved under tumor to 2cm intestinal tube place again after locking, the position of marked tumor accurately and reliably, guarantee closed when disconnected incisxal edge feminine gender;
3, this lasso trick from disconnected rectum cause for having blocked enteric cavity, can guarantee to rinse far-end rectum thoroughly and effectively, reduced the danger of had postoperative recurrent tumor;
4, due to contraction and the blocking-up of lasso trick, the ampulla of rectum expanding is dwindled, the closed process of cutting of being expert at substantially 1 nail bin just can be completely from heartbroken pipe, has not only saved medical treatment cost but also has reduced the risk of anastomotic leakage.
In sum, this utility model is simple in structure, easy to operate, accurate positioning, and when facilitating doctor to perform the operation, the damage to intestinal tube while also having alleviated operation.
Just accompanying drawings and embodiment further illustrate this utility model below.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model deployed condition;
Fig. 2 is the structural representation that this utility model tightens up state;
Fig. 3 is using state structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, for this utility model provide a kind of for locating the lasso trick of rectum, comprise sleeve pipe 3, in sleeve pipe, be provided with steel wire rope 4, steel wire rope one end is connected with hook, described hook comprises plunger body 6, plunger body one end is hemispherical, the other end is provided with and the close-fitting boss 5 of internal surface of sleeve pipe, plunger body one side is provided with and the orthogonal open slot 6a of its axis, open slot one side is provided with wedge-shaped slot 6b, wedge-shaped slot and open slot are interconnected, described steel wire rope 4 is through sleeve pipe 3, sleeve pipe latter end is provided with handle 1, handle one side is provided with and the orthogonal clamping screw 2 of its axis, clamping screw is through hands handle, its bottom is placed in sleeve pipe, when clamping screw bottom is threaded on sleeve lining, clamping screw 2 forms location with steel wire rope 4 and coordinates.
Using method
First by steel wire rope 4 tensions, the hook 6 of its one end is closely connected with sleeve pipe 3 one end, then by screwing clamping screw 2 so that steel wire rope is located, thereby reach the state (as shown in Figure 2) tightening up; After rectum is suitably free, then this utility model having tightened up is imported in puncture outfit casing tube, then unscrew clamping screw, steel wire rope is pulled out, thereby reach the state (as shown in Figure 1) of expansion; Last again hook after one week, is hooked to steel wire rope around the rectum after free, make steel wire loop on rectum, thereby reach the state (as shown in Figure 3) of work.At steel wire loop, behind rectum appropriate location, then locking nut is screwed, with tense wire rope location, form lasso trick.
As long as operator when free is to all directions tractive lasso trick.After free end, can unscrew clamping screw, the position of adjusting lasso trick is positioned at the position of tumor lower edge 2cm, to guarantee that from intestinal external labeling knub position incisxal edge is negative exactly.Owing to blocking and having shunk enteric cavity, can rinse thoroughly safely enteric cavity, and make to cut the simple and convenient of closed intestinal tube simultaneously.After heartbroken pipe, untie lasso trick, by this utility model being adjusted into the state that tightens up, again it is taken out in puncture outfit casing tube.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, or else relevant staff can depart from the category of this utility model technological thought completely, carries out various change and modification.The technical category of this utility model is not limited to the content in description, must determine its technical scope according to claim scope.
