Abstract

The utility model provides a novel tumor cutting knife, and relates to the technical field of medical equipment of the oncology department. The novel tumor cutting knife comprises a sharp knife head (1), a blunt knife head (2), a knife handle (3), a suction tube (4), a stainless steel connecting chain (5) and an expansion arm (6), wherein the sharp knife head (1) is arranged at the front end of the knife handle (3), the blunt knife head (2) is arranged on one side of the sharp knife head (1), the suction tube (4) is arranged on the outer side of the sharp knife head (1) and the outer side of the knife handle (3), and the tail end of the knife handle (3) is connected with the expansion arm (6) through the stainless steel connecting chain (5). The novel tumor cutting knife is simple in structure, novel and reasonable in design, and various in function, can not only carry out tumor blunt separation, but also carry out tumor sharp separation, can also carry out incision traction and hydrops attraction in an operation process, and not only reduces workload of medical workers, but also improves working efficiency of the medical workers.

Description

A kind of Novel tumor cutting knife

Technical field:

This utility model relates to the oncology technical field of medical instruments, is specifically related to a kind of Novel tumor cutting knife.

Background technology:

At present clinically when cutting tumor to patient, great majority all are to adopt drag hook tractive operative incision, then adopt scalpel to excise, also to adopt suction catheter that the hydrops in the operation process is drawn to open up the visual field in the excision process, waste time and energy like this, and the meeting that has in the excision process uses the method that passivity and sharp property combine and separates contacting between lump and the surrounding health tissue, therefore in operation process, usually need take the separately object of passivity of surgical staff to carry out lump and separate, increase workload to the healthcare givers, reduced healthcare givers's medical efficiency.

The utility model content:

The purpose of this utility model provides a kind of Novel tumor cutting knife, it is simple in structure, rationally novel in design, function is varied, both can carry out blunt separation to tumor, also can carry out the cutting of sharp property to tumor, and can also in the process of operation, carry out the tractive otch and attract hydrops, not only reduce the workload of medical worker, also improved the work efficiency of medical worker simultaneously.

In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises sharp property cutter head 1, passivity cutter head 2, handle of a knife 3, suction catheter 4, rustless steel connection chain 5 and expansion arm 6, the front end of handle of a knife 3 is provided with sharp property cutter head 1, one side of sharp property cutter head 1 is provided with passivity cutter head 2, the arranged outside of sharp property cutter head 1 and handle of a knife 3 has suction catheter 4, and the end of handle of a knife 3 is connected with expansion arm 6 by rustless steel connection chain 5.

Described expansion arm 6 adopts elastic plastic material to make.

The end of described suction catheter 4 is connected with effusion aspirator.

When this utility model uses, adopt expansion arm 6 with the visual field that operative incision carries out tractive expansion operation, the hydrops that then cuts in the process adopts suction catheter 4 to blot only, adopts sharp property cutter head 1 and passivity cutter head 2 to be used alternatingly and carries out the tumor cutting.

The utlity model has following beneficial effect: it is simple in structure, rationally novel in design, function is varied, both can carry out blunt separation to tumor, also can carry out the cutting of sharp property to tumor, and can also in the process of operation, carry out the tractive otch and attract hydrops, not only reduce the workload of medical worker, also improve the work efficiency of medical worker simultaneously.

Description of drawings:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of expansion arm.

The specific embodiment:

With reference to Fig. 1-2, this specific embodiment is taked following technical scheme: it comprises sharp property cutter head 1, passivity cutter head 2, handle of a knife 3, suction catheter 4, rustless steel connection chain 5 and expansion arm 6, the front end of handle of a knife 3 is provided with sharp property cutter head 1, one side of sharp property cutter head 1 is provided with passivity cutter head 2, the arranged outside of sharp property cutter head 1 and handle of a knife 3 has suction catheter 4, and the end of handle of a knife 3 is connected with expansion arm 6 by rustless steel connection chain 5.

Described expansion arm 6 adopts elastic plastic material to make.

The end of described suction catheter 4 is connected with effusion aspirator.

When this specific embodiment is used, adopt expansion arm 6 with the visual field that operative incision carries out tractive expansion operation, the hydrops that then cuts in the process adopts suction catheter 4 to blot only, adopts sharp property cutter head 1 and passivity cutter head 2 to be used alternatingly and carries out the tumor cutting.

This specific embodiment has following beneficial effect: it is simple in structure, rationally novel in design, function is varied, both can carry out blunt separation to tumor, also can carry out the cutting of sharp property to tumor, and can also in the process of operation, carry out the tractive otch and attract hydrops, not only reduce the workload of medical worker, also improve the work efficiency of medical worker simultaneously.
