Abstract

The utility model discloses a pair of bladder forceps which comprises a forceps head composed of a curved upper forceps head (1) and a curved lower forceps head (2), and a forceps handle composed of an upper forceps handle (4) and a lower forceps handle (5), wherein the curved upper forceps head (1) is fixedly connected with the lower forceps handle (5), the curved lower forceps head (2) is fixedly connected with the upper forceps handle (4), the upper forceps handle (4) is rotationally connected with the lower forceps handle (5), upper locking teeth (6) are formed on the upper forceps handle (4), lower locking teeth (7) are formed on the lower forceps handle (5) and engaged with the upper locking teeth (6), a curved upper rack (11) is arranged on the inner surface of the curved upper forceps head (1), and a curved upper rack (21) is arranged on the inner surface of the curved lower forceps head (2) and engaged with the curved upper rack (11). The bladder forceps can ensure that the neck of a bladder is effectively clamped on the premise of not increasing the cross-sectional area of the forceps head.

Description

Bladder forceps

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of bladder forceps.

Background technology

Bladder forceps is a kind of medical apparatus and instruments commonly used in the operation, and the clamp neck of bladder base of a fruit is used when supplying cystectomy.

Present existing bladder forceps; Comprise binding clip of forming by shaped form upper grip head and shaped form lower pliers head and the pincers handle of forming by upper plier handle and lower plier handle; Shaped form upper grip head and lower plier handle are fixedly linked, and shaped form lower pliers head and upper plier handle are fixedly linked, and upper plier handle and lower plier handle are rotatedly connected; Be provided with sealed tooth on the upper plier handle, be provided with on the lower plier handle with on the following sealed tooth that matches of sealed tooth; The inner surface (promptly facing the face of shaped form upper grip head) of inner surface of shaped form upper grip head (promptly facing the face of shaped form lower pliers head) and shaped form lower pliers head is shiny surface.Exist following defective during the actual use of above-mentioned bladder forceps: the contact area of shaped form upper grip head and shaped form lower pliers head and the neck of bladder base of a fruit is little, therefore is easy to take place slip phenomenon; Owing to receive the restriction of human abdominal cavity internal volume, can not increase the chucking power of whole binding clip through the cross section that increases shaped form upper grip head and shaped form lower pliers head again to the neck of bladder base of a fruit.

Summary of the invention

The technical problem that this utility model will solve provides a kind of bladder forceps that under the prerequisite that does not increase the binding clip cross section, can guarantee the neck of bladder base of a fruit is carried out effective clamping.

In order to solve the problems of the technologies described above; This utility model provides a kind of bladder forceps, comprises binding clip of being made up of shaped form upper grip head and shaped form lower pliers head and the pincers handle of being made up of upper plier handle and lower plier handle, and shaped form upper grip head and lower plier handle are fixedly linked; Shaped form lower pliers head and upper plier handle are fixedly linked; Upper plier handle and lower plier handle are rotatedly connected, and are being provided with sealed tooth on the upper plier handle, be provided with on the lower plier handle with on the following sealed tooth that matches of sealed tooth; Inner surface at the shaped form upper grip head is provided with the shaped form upper rack, tooth bar under the shaped form that the inner surface setting and the shaped form upper rack of shaped form lower pliers head matches.

Improvement as the bladder forceps of this utility model: the tooth under tooth on the shaped form upper rack and the shaped form on the tooth bar is the round end tooth.

The bladder forceps of this utility model, owing to the shaped form upper rack is set at the inner surface of shaped form upper grip head, tooth bar under the shaped form that the inner surface setting and the shaped form upper rack of shaped form lower pliers head matches; Therefore can increase the chucking power of whole binding clip to the neck of bladder base of a fruit.Because tooth under the shaped form on the tooth bar and the tooth on the shaped form upper rack are the round end tooth, therefore can not cause damage to the neck of bladder base of a fruit.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of this utility model is done further explain.

Fig. 1 is the main TV structure sketch map of the bladder forceps of this utility model;

Fig. 2 is that Fig. 1 removes and looks up the amplification partial schematic diagram behind shaped form lower pliers head 2 and the upper plier handle 4;

Fig. 3 is that Fig. 1 removes and overlooks the amplification partial schematic diagram behind shaped form upper grip head 1 and the lower plier handle 5.

The specific embodiment

Fig. 1～Fig. 3 combines to have provided a kind of bladder forceps; Comprise binding clip of forming by shaped form upper grip head 1 and shaped form lower pliers head 2 and the pincers handle of forming by upper plier handle 4 and lower plier handle 5; Shaped form upper grip head 1 is fixedly linked with lower plier handle 5, and shaped form lower pliers head 2 is fixedly linked with upper plier handle 4, and upper plier handle 4 is rotatedly connected through pincers arbor pin 3 with lower plier handle 5; Be provided with sealed tooth 6 on the upper plier handle 4, be provided with on the lower plier handle 5 with on the following sealed tooth 7 that matches of sealed tooth 6; The same prior art of said structure, the also same prior art of its method for using.

Inner surface (promptly facing the face of shaped form lower pliers head 2) at shaped form upper grip head 1 is provided with shaped form upper rack 11, tooth bar 21 under the shaped form that inner surface (promptly facing the face of shaped form upper grip head 1) is provided with and shaped form upper rack 11 matches of shaped form lower pliers head 2.Tooth under tooth on the shaped form upper rack 11 and the shaped form on the tooth bar 21 is the round end tooth.

During the actual use of this bladder forceps; Through handling upper plier handle 4 and lower plier handle 5; Thereby control shaped form upper grip head 1 is opened with shaped form lower pliers head 2 relatively; Make the neck of bladder base of a fruit between shaped form upper grip head 1 and shaped form lower pliers head 2, it is closed relatively with shaped form lower pliers head 2 to control shaped form upper grip head 1 again, the relative position relation between the last sealed tooth 6 that cooperatively interacts and down sealed tooth 7 locked shaped form upper grip heaies 1 of ability and the shaped form lower pliers head 2.At this moment, under the cooperation of tooth bar 21, shaped form upper grip head 1 can grasp the neck of bladder base of a fruit firmly with shaped form lower pliers head 2 under shaped form upper rack 11 and shaped form, thereby avoids the slippage from the bladder forceps of the neck of bladder base of a fruit.

At last, it is also to be noted that what more than enumerate only is a specific embodiment of this 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 the protection domain of this utility model.
