Detailed Description

The technical solution of the present invention is clearly and completely explained below with reference to the accompanying drawings through the concrete implementation of the embodiments of the present invention.

Please refer to fig. 1-4, the present invention relates to a tumor clamping forceps capable of replacing the head type, the middle of the head 1 of the clamping forceps is provided with a hinge point 4, and is rotatably connected with the legs 7 of the clamping forceps through the hinge point 4, and the two ends of the head 1 are respectively provided with a straight claw 2 and a curved claw 5.

The curved jaws 5 are L-shaped with bent ends, so that the tumor can be grasped from the side. The two binding clip 1 are respectively hinged with the two binding clip legs 7, and the two binding clip 1 are both positioned between the two binding clip legs 7. Therefore, in the case that the two legs 7 are located on the horizontal plane, the hinge point 4 is located on the side of the legs 7, and the two binding clip 1 are connected to the side of the legs 7, and at this time, the rotation of the binding clip 1 also rotates in the vertical plane.

The jaw type of the utility model is equal to the type of the binding clip 1 in the name. The ordinary binding clip 1 that snatchs pincers only has a jaw shape, and the utility model discloses have two kinds of jaw shapes to the jaw of two kinds of shapes can the switched position use, makes one snatch the work that the pincers can accomplish two kinds of differences, consequently can reduce the quantity that snatchs pincers in the apparatus dish, thereby lets out more spaces for other apparatus.

When the clamping pincers are used, the stability of the clamping pincers needs to be ensured. Since the binding clip 1 is rotatable with respect to the leg 7, a fixed portion is provided between the binding clip 1 and the leg 7. The fixing part is used for fixing the clamp head 1 and the clamp legs 7. Under the action of the fixing part, the tong head 1 and the tong legs 7 cannot move relatively, so that the clamping tongs can stably play a role in clamping when in use.

Preferably, the fixing part comprises a positioning pin 8 arranged on the clamp leg 7 and a positioning hole 3 arranged on the clamp head 1. In the case of both legs 7 lying in a horizontal plane, the axis of the locating hole 3 also lies in the horizontal plane. Therefore, the bit 1 cannot rotate in the vertical plane due to the positioning action of the positioning pin 8 from the horizontal direction. The tong head 1 only has the freedom of rotating around the hinge point 4, so the tong head 1 is fixed.

Since the two ends of the binding clip 1 are two claws with different shapes, the two claws need to be fixed when used respectively. The binding clip 1 is provided with two positioning holes 3, and the distance between the two positioning holes 3 and the hinge point 4 is the same. When the straight claw 2 is needed to be used for clamping, the positioning pin 8 is matched with the positioning hole 3 at the end of the bent claw 5. On the contrary, when the bent claw 5 is needed to perform the clamping operation, the positioning pin 8 is matched with the positioning hole 3 at the end of the straight claw 2.

Since the shape of the bent jaw 5 is L-shaped, the main body portion is still straight, and only the end portion is bent laterally, the two positioning holes 3 are symmetrically arranged relative to the hinge point 4.

The positioning pin 8 needs to be able to be inserted into and withdrawn from the positioning hole 3, so as to facilitate the locking and unlocking of the binding clip 1. The clamp leg 7 is provided with a through hole, the through hole is used for the positioning pin 8 to pass through, and the positioning pin 8 is fixed on the outer side of the clamp leg 7 through a spring piece 9. That is to say, one end of the positioning pin 8 is fixedly connected with the spring piece 9, and the other end of the positioning pin passes through the through hole on the clamp leg 7 and then is matched with the positioning hole 3 on the clamp head 1. When the clamp head 1 needs to be rotated to replace the clamp claw, the positioning pin 8 needs to be withdrawn from the positioning hole 3. The spring plate 9 is bent during the process of the positioning pin 8 being withdrawn from the positioning hole 3. After the binding clip 1 is rotated away, the spring force of the spring leaf 9 causes the positioning pin 8 to spring back to the original position. When the other end of the binding clip 1 is turned over again, the positioning pin 8 needs to be pushed to move towards one side of the spring piece 9 again, and when the other positioning hole 3 of the binding clip 1 is coaxial with the through hole, the elastic force of the spring piece 9 can drive the positioning pin 8 to be inserted into the positioning hole 3. The elasticity of the spring piece 9 ensures the stability of the positioning pin 8, so that the positioning pin 8 cannot be separated from the positioning hole 3 at will.

One side surface of the spring piece 9 is connected with the side surface of the clamp leg 7 in a welding or screw fixing mode. In the above process, since the positioning pin 8 has no obvious stress point, it is difficult to directly push the positioning pin 8 to move. The spring plate 9 is provided with a raised structure at its edge. The spring plate 9 is in a vertical state with both legs 7 in a horizontal plane, and the raised structures are located on the upper and lower sides of the spring plate 9 and protrude from the upper and lower sides so that a person's fingers can press directly from the side against the raised structures. When the protruding structure is pressed by fingers, the spring piece 9 is deformed, so that the positioning pin 8 is driven to move.

Therefore, when the tong head 1 needs to be rotated, only one finger is needed to press the protruding structure of one spring piece 9, then the tong head 1 can be rotated by the other hand, the other end of the tong head 1 is rotated to the inner side surface of the tong leg 7, then the spring piece 9 is loosened, the tong head 1 swings back and forth, and therefore the positioning pin 8 under the action of the elastic force is inserted into the positioning hole 3, and the purpose of replacing the shape of the tong claw is achieved. After the position of one binding clip 1 is rotated, the other binding clip 1 can be replaced in the same way.

The raised formations are lateral extensions of the spring plate 9. The shape of the convex structure is semicircular or rectangular. When the shape of the protruding structure adopts a semi-circle shape, the hand or the tissue of a patient can be prevented from being punctured by the corners of the protruding structure. And the corners of the spring piece 9 are also rounded, so as to avoid the corners of the spring piece 9 from stabbing hands or patient tissues.

The spring plate 9 and the positioning pin 8 can be connected by welding.

The positioning pin 8 needs to penetrate through the through hole and then is matched with the positioning hole 3, so that the length of the positioning pin 8 is larger than the thickness of the clamp leg 7, and the end part of the positioning pin 8 is hemispherical. The end of the positioning pin 8 is formed in a hemispherical shape so that the end of the positioning pin 8 can slide smoothly when abutting against the side surface of the binding clip 1.

The pliers head 1 is provided with a sliding groove 6 for guiding, the sliding groove 6 is arc-shaped, the circle center of the sliding groove 6 is a hinge point 4, and the positioning hole 3 is overlapped with the sliding groove 6. After the sliding groove 6 is arranged, the positioning pin 8 can only slide along the direction of the sliding groove 6, and the sliding groove 6 can prevent the positioning pin 8 from being deformed and dislocated in use and being incapable of sliding into the positioning hole 3. Therefore, the sliding groove 6 is arranged to solve the problem that the positioning pin 8 and the positioning hole 3 cannot be quickly positioned. Only the positioning pin 8 is required to slide along the slide groove 6 and then inevitably passes through the positioning hole 3, and when the positioning pin 8 passes through the positioning hole 3, it inevitably slides into the positioning hole 3 by the elastic force of the spring piece 9. The positioning and fixing function of the binding clip 1 is realized.
