Description

Surgical scissors for cutting deep circular tissue

The technical field is as follows:

the utility model relates to the technical field of medical equipment, concretely relates to surgical scissors for excision of deep circular tissue.

Background art:

at present, various hyperplastic organisms or necrotic tissues such as lesions, tumors and the like in a human body cavity are generally cut off by adopting an operation mode, some hyperplastic organisms on the body surface can be cut off by using common operation scissors, but for the hyperplastic organisms or necrotic tissues at the esophagus, colon and other internal organs, the common operation scissors are difficult to cut off, the outer walls of some organs such as the intestinal wall are smooth, when a doctor cuts off the intestinal wall by using the operation scissors, the intestinal wall is easy to slide on the blade of the scissors and is not easy to cut off, and the operation of the doctor is inconvenient. Patent No. ZL201520242552.3 is through setting up by first handle and the second handle of the articulated mutually of the body of round pin, first handle and second handle head are equipped with first pincers beak and second pincers beak, first pincers beak and second pincers beak inboard all are equipped with the cutting edge, first pincers beak and second pincers beak inboard all establish the triangle-shaped cutting edge, can prevent when medical staff's scissors from cutting the intestinal wall, the intestinal wall slides on the scissors, all be equipped with the scale on first pincers beak and the second pincers beak, the accuracy is improved, but this kind of scissors is shearing the position dark, it is more difficult when the tissue in narrow and small space, especially shear the circular tissue that has certain toughness, it easily produces the slip to cut the point during shearing, be difficult to cut, and incised wound face is untidy.

The utility model has the following contents:

technical problem to be solved

The utility model aims at providing a surgical scissors for dark circular tissue excision for the tissue in the dark, narrow and small space of position is cut, solves current surgical scissors and when cutting the circular tissue that has certain toughness, cuts the point and easily produces and slide, is difficult for cutting, and cuts the uneven problem of face of creating.

The technical scheme is as follows:

in order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a surgical scissors for excision of deep circular tissue, cuts the handle including first handle and the second of cutting, first cut the handle with the second is cut the handle and is rotated the connection through rotating, first cut the handle with the tail end that the handle was cut to the second all is equipped with the ring, first cut the handle with the front end that the handle was cut to the second all is equipped with the cutting head, the cutting head for first cut the handle with the axis direction that the handle was cut to the second is the arc 90 degrees of buckling, be equipped with the shearing sword on the cutting head.

The first shearing handle and the second shearing handle rotate around the rotating piece, the shearing head bends 90 degrees in an arc shape relative to the axial direction of the first shearing handle and the second shearing handle, the shearing head is used for contacting with a round tissue with a deeper position, shearing force is generated by mutual sliding of the shearing blades to shear the round tissue, the shearing blades are vertically crossed with the tissue to be sheared, the tissue cannot slide along the tissue, the shearing effect is effectively guaranteed, and the surface of the cut wound is kept neat.

Furthermore, the top of cutting head is equipped with the arc and cuts the point, cut the arcuation structure that the sword is the indent, and with the arc is cut the point and is connected, the arc is cut point and arcuation structure cut the sword and can live and cut circular tissue circle, guarantee to cut the integrality of tissue, make things convenient for follow-up section to carry out external inspection to the tissue that comes down.

Furthermore, the outside of cutting head is equipped with semicircular hook, two on the cutting head semicircular hook mutually supports and forms the ring structure, can catch the circular tissue root that needs to be cut off, is convenient for the shearing sword is cut off, guarantees to cut thoroughly, cuts the face of creating neatly.

Further, be equipped with the silica gel cover in the ring, the silica gel cover is used for contacting with operator's finger, improves frictional force and comfort, prevents that the finger from sliding when operating and influencing the accuracy.

(III) the beneficial effects are as follows:

compared with the prior art, the utility model discloses the beneficial effect who produces is: the front end of cutting the handle through first handle and the second of cutting respectively sets up and is the arc 90 degrees of buckling's cutting head for the axis direction of first handle and the second is cut, sets up on the cutting head and cuts the sword, can be when shearing the darker circular tissue in position, make cut the sword and need cut the tissue that removes perpendicularly crossing, cut the sword and produce the shearing force through the mutual slip and cut circular tissue and remove, can not slide along the tissue, effectively guarantee the shearing effect, cut the surface of a wound simultaneously and keep neat.
