Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. However, it should not be understood that the scope of the above-mentioned subject matter is limited to the following embodiments, and all the technologies realized based on the present invention are within the scope of the present invention.

Example 1

As shown in fig. 1-2, a peritoneoscope does not have wound separation pincers, contain handle, transfer line and binding clip, the handle contains fixed handle 11 and movable handle 12, the binding clip contains two articulated pincers pieces 2, the transfer line is used for driving two pincers pieces 2 are close to or separate, 2 articulated connecting rod 4 that are connected with of pincers piece, preferred, pincers piece 2 is connected with connecting rod 4 through torsional spring 3, pass through promptly torsional spring 3 realizes rotating the connection, connecting rod 4 can for pincers piece 2 rotates, just the restoring force of torsional spring 3 can be convenient for pincers piece 2 is kept away from or is drawn in, two connecting rod 4 articulates the connection, connecting rod 4 is the stainless steel member, the last tong tooth that has of pincers piece 2.

The distance between the first hinge shaft 51 of the two connecting rods 4 and the second hinge shaft 52 of the two forceps pieces 2 is smaller than the length of the forceps pieces 2, namely, the first hinge shaft 51 is positioned at the inner side of the forceps head, the torsion spring 3 is arranged at one end of the forceps pieces 2, which is far away from the second hinge shaft 52, namely, the free ends of the forceps pieces 2 are beneficial to ensuring the size of the region enclosed by the forceps head, so that the sufficient exposure of the operative field is further ensured, the distance between the torsion spring 3 and the free ends corresponding to the forceps pieces 2 is 0.3-1cm, so that the tip of the forceps head is conveniently reserved for forceps holder tissues, and meanwhile, the observation is facilitated by means of the region enclosed by the connecting rods 4 and the forceps pieces 2.

When the fixed handle 11 and the movable handle 12 are far away, the two forceps sheets 2 are far away, as shown in fig. 2, when the handles are not stressed, the two forceps sheets 2 are far away, the two forceps heads are not acted by the torsion spring 3 and do not reach the maximum opening angle, when the fixed handle 11 and the movable handle 12 are operated to be far away, the included angle between the two connecting rods 4 facing to the outer side (the right direction in fig. 2) is 170-180 degrees, at this time, the forceps heads are opened to the maximum, the forceps sheets 2 and the connecting rods 4 enclose a triangular or approximately triangular area for presenting an operation visual field, and when the handles are loosened, the two forceps sheets 2 can be folded under the restoring force action of the torsion spring 3, so that the forceps heads are convenient to operate and clamp to avoid being blocked; when the binding clip reaches the maximum opening angle, a limiting part is adopted for limiting, so that the included angle between the two connecting rods 4 is prevented from exceeding 180 degrees, and the first hinge shaft 51 exceeds the binding clip when the two binding clips 2 are folded; when the handles are operated to make the fixed handle 11 and the movable handle 12 close, as shown in fig. 3-4, the two forceps sheets 2 can be closed, so that the forceps head can clamp tissues.

Adopt a peritoneoscope does not have wound separation pincers, compare in prior art, this application is two be equipped with two articulated connecting rods 4 between the pincers piece 2, every connecting rod 4 is connected through torsional spring 3 and is corresponding pincers piece 2, consequently, work as two when pincers piece 2 separates, can drive two connecting rod 4 separation makes binding clip department has one and passes through the region that pincers piece 2 and connecting rod 4 enclose makes the area of contact greatly increased of binding clip and tissue is favorable to fully exposing in the operation field of vision, and the one-hand operation during the operation of being convenient for, the security and the efficiency of operation can effectively improve to do not increase the size of separation pincers, also do not increase the operation complexity of separation pincers, can not additionally increase patient's economic burden.

Of course, it can be arranged that when the fixed handle 11 and the movable handle 12 are close, the two forceps blades 2 are far away.

Example 2

A peritoneoscope does not have wound separation pincers, its structure is roughly the same with embodiment 1, its difference lies in, pincers piece 2 has well kenozooecium 6, promptly pincers piece 2 is hollow out construction, as shown in figure 5, 2 pincers positions of pincers piece and offside link up the setting well kenozooecium 6 sets up well kenozooecium 6 is favorable to stablizing the pincers tissue, connecting rod 4 corresponds the connection torsional spring 3 is connected in corresponding the lateral wall of well kenozooecium 6 of pincers piece 2 is convenient for two when pincers piece 2 draws in, connecting rod 4 can be accomodate well kenozooecium 6 is favorable to reducing the width of binding clip can also avoid connecting rod 4 appears crooked leading to the binding clip is opened and shut the difficulty.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
