Abstract
The utility model discloses tumor extracting pliers which comprise an external sleeve tube, a connecting rod and sealing blocks arranged at two ends of the external tube. A handle is fixedly arranged at one end of the connecting rod, two semicircle clamping arms are arranged at the other end of the connecting rod, end portions of the two clamping arms are shaft connected with the connecting rod, a spring is fixedly arranged between the two clamping arms, the sealing blocks are arranged inside the external sleeve tube, the sealing blocks are fixedly connected with the external sleeve tube, a finger ring sleeve is arranged on the external sleeve tube, and the finger ring sleeve is connected with the external sleeve tube in an inserting mode. One end of a return spring abuts against the handle, the other end of the return spring abuts against the finger ring sleeve, finger rings are arranged at two sides of the finger ring sleeve, and the finger rings and the finger ring sleeve are formed integrally during manufacturing. The external sleeve tube is cylindrical, and the diameter of a ring formed by the clamping arms is larger than the hole diameter of the external sleeve tube. The tumor extracting pliers are simple in structure, convenient to use, firm in clamping and not prone to falling, and capable of taking a cut tumor out of a cut portion quickly.
Description
Technical field:
This utility model relates to technical field of medical instruments, relates in particular to a kind of tumor extraction forceps.
Background technology:
After tumor resection, need to be with tumor from excision position taking-up, existing tumor removal equipment is tweezers, there are many drawbacks and take out tumor tissues with tweezers: as, tumor tissues is slided, is come off when causing gripping, in addition, tweezers gripping tumor tissues, it only has two stress points, firmly too little, can't clamp tumor tissues, firmly excessive, easily clip broken or be caught broken tumor tissues, if be caught broken, also need to use the suction pump sucking-off, increase operating time and program, can serve unnecessary difficulty to surgical band.
In view of above-mentioned Technology Need, a kind of simple in structure, easy to use in the urgent need to occurring, clamping does not firmly come off, a kind of tumor extraction forceps that the tumor of excision can be taken out from excising the position fast.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in prior art, provides a kind of simple in structure, easy to use, and clamping does not firmly come off, a kind of tumor extraction forceps that the tumor of excision can be taken out from excising the position fast.
for achieving the above object, this utility model provides a kind of tumor extraction forceps, comprise trocar sheath, connecting rod and the sealing block that is arranged on the trocar sheath two ends, wherein, one end of described connecting rod is fixedly installed the hands handle, the other end is provided with the clamping limb of two semicircle shapes, between the end of two clamping limbs and connecting rod, axle is connected, be fixedly installed spring between two clamping limbs, described sealing block is positioned at the inside of described trocar sheath, be fixedly connected with between described sealing block and described trocar sheath, be provided with the finger ring cover on described trocar sheath, described connecting rod and finger ring cover, plug together connection between sealing block.
Be socketed with return spring on one section connecting rod between described handle and described finger ring cover, plug together between described finger ring cover and described trocar sheath and be connected, one end of described return spring withstands on handle, the other end withstands on finger ring and puts, the both sides of described finger ring cover are provided with finger ring, and described finger ring and described finger ring cover are one-body molded during fabrication.
Described trocar sheath is cylindric, and the diameter of the annulus that clamping limb consists of is greater than the aperture of trocar sheath.
Advantage of the present utility model is that simple in structure, easy to use, clamping does not firmly come off, and the tumor of excision can be taken out from excising the position fast.Be specially:
This utility model selects the pipe of hollow as trocar sheath, the two ends of the inside of trocar sheath are provided with sealing block, one end of trocar sheath is plugged and connected with the finger ring cover, one end of connecting rod is connected with two clamping arm axles after running through finger ring cover, sealing block, the other end mounting handle of connecting rod, be socketed with return spring on the connecting rod of this end of mounting handle, two clamping limbs consist of annulus, are provided with spring between two clamping limbs.When this utility model uses, aim at the tumor tissues that needs extraction, press handle, the annulus of two clamping limb formations is pushed away trocar sheath by connecting rod, under the tension force effect of spring, two clamping limbs open, after the part that clamping limb opens faces toward tumor tissues, release handle, handle resets under the effect of return spring, clamping limb bounces back under the effect of connecting rod, because of the resistance of trocar sheath end, clamping limb consists of circular, and tumor tissues is picked up in clamping limb, at this moment, taking out fast tumor tissues gets final product.
