Description
Technical field
This utility model belongs to field of medical equipment technology, particularly relates to a kind of tumor extraction forceps.
Background technology
Tumor (Tumor) be body under various carcinogenic factor effect, some cells of local organization lose the normal regulation to its growth on gene level, cause its clonal abnormality hypertrophy and the abnormality that formed.Tumor is generally divided into optimum and pernicious two large classes by educational circles.The tissue of ocal resection and diffusion thereof is one of effective means for the treatment of tumor.
Tumor extraction forceps is apparatus the most frequently used in current tumor resection, is mainly used in gripping or excision deep tumor.Tumor extraction forceps head is rounded or oval generally, and gripping area is residual greatly few, and surface is round and smooth, can not cause peripheral tissue injury.Existing tumor extraction forceps is all adopt held by both hands clamp handle to carry out gripping tumor, and like this during lift tumor tumor body, the bad grasp of dynamics and very easily extrude tumor body and cause tumor ulceration, adds the probability of tumor diffusion transfer.Meanwhile, because the tumorous size of tumor is different, the tumor body that existing extraction pincers can not be applicable to different size is won.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of tumor extraction forceps that can adjust jaw folding size, avoid tumor ulceration.
The purpose of this utility model is achieved through the following technical solutions.
A kind of tumor extraction forceps, comprise jaw and tong arm, also comprise the first pincers cheek, the second pincers cheek and hands handle, the rear end of described handle is connected with extension rod by bending axle, described bending axle is provided with latch, the front end of the described first pincers cheek and the described second pincers cheek is provided with tong arm, the front end of tong arm described in each is all connected with a jaw, the inner side of the described first pincers cheek is provided with notch board, the inner side of the described second pincers cheek is provided with the gusset plate matched with described notch board, described gusset plate is connected by jointed shaft with described notch board, the rear end of the described first pincers cheek is provided with spin axis, the front end of described spin axis is positioned at the inner side of the first pincers cheek, the top of described handle is fixed in described spin axis, this handle is provided with screw thread, described screw thread is provided with transfer block, described transfer block clamps the cheek by screw and described second and is connected.
Further, described screw is manual adjustment screw.
The beneficial effect that this utility model produces owing to taking above-mentioned technological means is: tumor extraction forceps of the present utility model, by rotary screw and handle, can adjust the folding size of jaw, thus the tumor of the different size of gripping.Meanwhile, after rotary screw and handle put in place, jaw and tong arm can keep constant for the chucking power of tumor tumor body, avoid and cause tumor body ulceration to the excessive compression of tumor body.In addition, connect extension rod in the rear end of handle by bending axle, so just shape between handle and extension rod can be had a certain degree by bending axle, be convenient to and other operating theater instruments compounding practice, be also convenient to appearing surgical field of view.By arranging latch, stable by using after handle and extension rod bending.
Accompanying drawing explanation
Fig. 1 is the structural representation of tumor extraction forceps of the present utility model.
In figure, 1-handle, 2-spin axis, 3-screw thread, 4-first clamps the cheek, and 5-second clamps the cheek, 6-notch board, 7-gusset plate, 8-jointed shaft, and 9-transfers block, 10-screw, 11-jaw, 12-tong arm, 13-extension rod, 14-bending axle, 15-latch.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Tumor extraction forceps of the present utility model as shown in Figure 1, comprise jaw 11 and tong arm 12, also comprise the first pincers cheek 4, the second pincers cheek 5 and handle 1, the rear end of handle 1 is connected with extension rod 13 by bending axle 14, bending axle 14 is provided with latch 15, the front end of the first pincers cheek 4 and the second pincers cheek 5 is provided with tong arm 12, the front end of each tong arm 12 is all connected with a jaw 11, the inner side of the first pincers cheek 4 is provided with notch board 6, the inner side of the second pincers cheek 5 is provided with the gusset plate 7 matched with notch board 6, gusset plate 7 is connected by jointed shaft 8 with notch board 6, the rear end of the first pincers cheek 4 is provided with spin axis 2, the front end of spin axis 2 is positioned at the inner side of the first pincers cheek 4, the top of handle 1 is fixed in spin axis 2, this handle 1 is provided with screw thread 3, screw thread 3 is provided with and transfers block 9, transfer block 9 clamps the cheek 5 by screw 10 and second and is connected.As preferably, screw 10 is manual adjustment screw.
The operation principle of tumor extraction forceps of the present utility model is as follows: before use, be rotated counterclockwise handle 1 and screw 10, jaw 11 is opened, after jaw 11 and tong arm 12 being fastened on tumor tumor body, turn clockwise handle 1, transfers block 9 and drive second is clamped the cheek 5 and draw close to the first pincers cheek 4, when surface contact with tumor tumor body of jaw 11 and tong arm 12, micrometer adjusting screw 10, makes jaw 11 and tong arm 12 fastening tumor tumor body.If when needing appear surgical field of view fully or be convenient to coordinate with other operating theater instruments, by bending axle 14, handle 1 and extension rod 13 shape are had a certain degree, angle can be made to fix by latch 15.
