It is lower to be detached from the histoorgan that clamps, and then the operative site that while sheltering from intracavity operation needs to appear.Optionally, described predetermined
Radian measure alpha can be adjusted according to the needs of different tissues.
The front end of the first part of first clamp arm 11 and the second clamp arm 12 is clamping face 15, for clamping tissue or device
Official.The clamping face 15 can be set to square planar, it is possible to reduce to tissue or organ clamping injury, while can also increase
Holding area, so that haulage clip 1 is stronger when clamping tissue or organ.The clamping face 15 can be and the first clamp arm 11
Or the integrally manufactured formation of the second clamp arm 12, it is also possible to be formed by way of welding or bonding.Optionally, the clamping face 15
It can be set to dentation engaging structure or be fixedly connected with rubber pad on the clamping face 15.Thus, it is possible to effectively prevent
Haulage clip 1 is detached from from tissue or organ, plays anti-skidding effect.
The second part of first clamp arm 11 and the second clamp arm 12 extends along the tail end of the first part respectively, the
When the first part of one clamp arm 11 and the second clamp arm 12 engages, predetermined angular β is formed, by external force by the first clamp arm 11 and second
The second part of clamp arm 12 is formed by predetermined angular β and gradually becomes smaller, so that the of the first clamp arm 11 and the second clamp arm 12
A part is opened.Optionally, the predetermined angular β can be configured according to different needs, with meet to different tissues into
Required opening angle when row clamping.It is clamped required for the haulage clip 1 is moved to after the first part opens
Tissue or organ at clamped, remove external force after, haulage clip 1 spring 14 itself elastic force effect under resetted, make
The first part for obtaining the first clamp arm 11 and the second clamp arm 12 is closed and then clamps histoorgan.First clamp arm 11 and second
The second part of clamp arm 12 is respectively arranged with handle hole 16, when for the haulage clip 1 to be placed in intracavitary, passes through surgical clamp etc.
Tool connect with handle hole 16 and then controls the opening or closure of haulage clip 1.
The intracavitary traction device further includes that long staight needle 3 or puncture needle 4 will be drawn for connecting with the draught line 2
Line 2 is pierced by be fixed in vitro.The tip portion of the puncture needle 4 is set as inclined plane shape, be provided on puncture needle 4 wire casing 41 or
Line hook 42, as shown in Figure 3 and Figure 4.Draught line 2 is placed on the wire casing 41 or line hook 42 of puncture needle 4, is pierced by external.Pass through length
Draught line 2 is pierced by body surface by staight needle 3 or puncture needle 4, is fixed in vitro.The position that is pierced by does not have scar, without suture, realizes
The convenience of operation is increased while noninvasive.
In another implementation, draught line 2 can be sewn on abdominal cavity by long staight needle 3 by tissue clamped by haulage clip 1
It is fixed on inner wall, and then appears operative site.
Schematic diagram when Fig. 5 is the intracavitary traction device progress intracavity operation of the embodiment of the present application.As shown in figure 5, into
When row intracavity operation, doctor opens a notch B in the body surface A of patient as required, then corresponding with size incision will wear
It pierces in cannula C (trocar) insertion notch B, forms the channel of surgical instrument disengaging, intracavitary traction device is then passed through into puncture
Cannula C is placed in intracavitary D；Then surgical clamp E is protruded into from cannula C to intracavitary D, under the guiding of hysteroscope, by the head of surgical clamp E
With 16 grafting of handle hole of first clamp arm 11 and the second clamp arm 12, surgical clamp E directly manipulates haulage clip 1 and clamps preset group
It knits；Surgical clamp E is withdrawn from, is connected with long staight needle 3 in the other end of draught line 2, the long staight needle 3 is pierced by stomach wall from intracavitary, or
Person is fixedly connected afterwards with draught line 2 from vitro wearing puncture needle 4 to intracavitary, draught line 2 is taken out of in vitro, in vitro by leading
Lead 2 pulls haulage clip 1 and makes fixed traction line 2 after the draw tissue to appropriate location, one may be implemented in doctor as a result,
Operation.If needing to adjust tissue clip position in art, haulage clip 1 can be adjusted with surgical clamp E and performed the operation again to suitable position.Hand
After the completion of art, draught line 2 can be cut in vitro finally, intracavitary traction device is taken out by cannula C, haulage clip 1 sterilizes
After can reuse.When necessary, can simultaneously by multiple intracavitary traction devices be placed in it is intracavitary clamp, preferably to show
Reveal operative site.The draught line 2 of the multiple intracavitary traction device can be pierced by external or seam by long staight needle 3 or puncture needle 4
System is fixed in internal abdominal wall.
