Abstract
The utility model discloses a direct-view intestinal grasping forceps, which comprises a handle, an outer tube (4), wheel components (3) and a forceps, etc. The forceps comprises an upper clamp (6) and a lower clamp (7) which is connected by rotation and mutual corresponded to each other. Root of the upper clamp (6) and root of the lower clamp (7) are respectively connected with the head end of a push rod component. Upper teeth (61) are installed on the inner-surface of the upper clamp (6). Lower teeth (71) meshed with the upper teeth (61) are installed on the inner surface of the lower clamp (7). Both the upper teeth (61) and the lower teeth (71) are of round head teeth. Both the top of the upper clamp (6) and the top of the lower clamp (7) are spherical. The aspect ratio of the inner-surface of the upper clamp (6) and the inner surface of the lower clamp (7) are 6.5 to 7.5:1. The direct-view intestinal grasping forceps are especially fit for grasping small and large intestines in surgeries.
Description
Technical field
This utility model relates to a kind of nipper, particularly a kind of direct-view intestinal nipper.
Background technology
Nipper is a kind of apparatus commonly used in the operation, and it is used to grasp Intraabdominal tissue (for example liver, stomach, intestinal etc.), is convenient to the doctor effectively observe in operation, looks operations such as whether the practical situation decision needs to excise accordingly then.Present existing nipper comprises the handle of being made up of pull end that is rotatedly connected and back handle, outer tube is rotatedly connected by wheel set assembly and pull end, top at outer tube is provided with caliper, in outer tube, be provided with the push-rod assembly that is used to control the caliper switch, the tail end of push-rod assembly links to each other with the back handle, caliper comprises and being rotatedly connected and mutually corresponding upper grip head and lower pliers head, the root of upper grip head links to each other with the head end of push-rod assembly respectively with the root of lower pliers head, at the inner surface of upper grip head tooth is set, the lower tooth that is meshed with last tooth in the inner surface setting of lower pliers head; On wheel set assembly, be provided with the bath joint that is connected with outer tube bore.During the actual use of this nipper, adjust the proper angle of caliper by the rotating wheel assembly, by the closed grasping tissue of upper grip head and lower pliers head.Above-mentioned existing nipper exists following defective: go up tooth and lower tooth and be conventional tip tooth, easily crawled tissue is caused damage.Because the top of upper grip head is a planar shaped, therefore the sidewall with upper grip head forms sharp right angle; Equally, the top of lower pliers head is a planar shaped, and therefore the sidewall with lower pliers head forms sharp right angle; The nipper of said structure hurts Intraabdominal tissue easily when intraperitoneal moves; Thereby cause injury to the patient.And above-mentioned nipper is to be common to grasp Intraabdominal tissue, so the length-width ratio of caliper is 3 ~ 4:1; Therefore and be not suitable for grasping large intestine and small intestinal.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of direct-view intestinal nipper that can not accidentally injure the intraperitoneal tissue and be particularly suitable for grasping large intestine or small intestinal.
In order to solve the problems of the technologies described above, this utility model provides a kind of direct-view intestinal nipper, comprise the handle of forming by pull end that is rotatedly connected and back handle, outer tube is rotatedly connected by wheel set assembly and pull end, top at outer tube is provided with caliper, in outer tube, be provided with the push-rod assembly that is used to control the caliper switch, the tail end of push-rod assembly links to each other with the back handle, caliper comprises and being rotatedly connected and mutually corresponding upper grip head and lower pliers head, the root of upper grip head links to each other with the head end of push-rod assembly respectively with the root of lower pliers head, at the inner surface of upper grip head tooth is set, the lower tooth that is meshed with last tooth in the inner surface setting of lower pliers head; On wheel set assembly, be provided with the bath joint that is connected with outer tube bore; Last tooth and lower tooth are the round end tooth; The top of upper grip head and the top of lower pliers head are sphere shape; The length-width ratio of the length-width ratio of upper grip head inner surface and lower pliers head inner surface is 6.5 ~ 7.5:1.
Direct-view intestinal nipper of the present utility model, the engagement of tooth and lower tooth grasping tissue firmly in the dependence, and because last tooth and lower tooth are round end tooth (being that crown is a circular arc), therefore the tissue surface that is held can not cause because of the damage of crown bleeding.Because the top of upper grip head and the top of lower pliers head are sphere shape, do not have sharp corner, therefore this direct-view intestinal nipper is touched in operation process or the roof pressure intraperitoneal just can not cause damage to it when organizing yet.Because the length-width ratio of caliper is that the length-width ratio of 6.5 ~ 7.5:1(upper grip head inner surface and the length-width ratio of lower pliers head inner surface are 6.5 ~ 7.5:1),, has increased the caliper length of existing nipper greatly that is, therefore be particularly suitable for grasping Intraabdominal large intestine or small intestinal.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the main TV structure sketch map of direct-view intestinal nipper of the present utility model;
Fig. 2 be among Fig. 1 A to amplification after partial schematic diagram;
Fig. 3 is the partial schematic diagram after the amplification of the caliper among Fig. 1 when being in closure state.
The specific embodiment
Fig. 1 ~ Fig. 3 comprises handle in conjunction with having provided a kind of direct-view intestinal nipper, and this handle is made up of pull end 11 that is rotatedly connected by screw of handle 13 and back handle 12, refers to circle 14 before the tail end of pull end 11 is provided with, and refers to enclose 15 after the tail end of back handle 12 is provided with.Outer tube 4 is rotatedly connected by wheel set assembly 3 and pull end 11, at the top of outer tube 4 caliper is set, and is provided with the push-rod assembly 5 that is used to control the caliper switch in outer tube 4; The tail end of push-rod assembly 5 links to each other with back handle 12, caliper comprises and being rotatedly connected and mutually corresponding upper grip head 6 and lower pliers head 7, the root of upper grip head 6 links to each other with the head end of push-rod assembly 5 respectively with the root of lower pliers head 7, is provided with the bath joint 2 with outer tube 4 intracavity inter-connections on wheel set assembly 3.At the inner surface of upper grip head 6 tooth 61 is set, the lower tooth 71 that is meshed with last tooth 61 in the inner surface setting of lower pliers head 7; The all same prior art of said structure, the also same prior art of its occupation mode.
Upward tooth 61 and lower tooth 71 are round end tooth (being that crown is a circular arc); The top of the top of upper grip head 6 and lower pliers head 7 is sphere shape, and after upper grip head 6 and lower pliers head 7 closures, the top of the top of upper grip head 6 and lower pliers head 7 is combined to form a hemispherical.The length-width ratio of the length-width ratio of upper grip head 6 inner surfacies and lower pliers head 7 inner surfacies is 6.5 ~ 7.5:1.
During the actual use of this direct-view intestinal nipper, adjust the proper angle of caliper indirectly by rotating wheel assembly 3, the closure by upper grip head 6 and lower pliers head 7 grasps large intestine or small intestinal.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, this utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of this utility model all should be thought protection domain of the present utility model.
